Abstract

A filtration dehydration apparatus, which comprises: a filter, composed of a filtration layer and an absorption layer while allowing the filtration layer that is orientated facing toward the absorption layer to be a first side, and allowing a surface of the absorption layer that is orientated facing toward the filtration layer to be a second side; a supporting structure, for supporting and fixedly securing the filter; a solid waste collector, for collecting solid object left on the first side; and an extrusion unit, for pressing the absorption layer to squeeze out water in the absorption layer; wherein the first side is provided for a solid-liquid mixture to be placed thereon so as to allow the liquid containing in the solid-liquid mixture to flow into the absorption layer through the filtration layer while enabling solid objects in the solid-liquid mixture to be filtered out and thus left on the first side.

First claim

What is claimed is:

1. A filtration dehydration apparatus, comprising:
a filter, composed of a filtration layer and an absorption layer while allowing a surface of the filtration layer that is orientated opposite to the absorption layer to be a first side of the filter, and allowing a surface of the absorption layer that is orientated opposite to the filtration layer to be a second side of the filter;
a supporting structure, for supporting and fixedly securing the filter;
a solid collector, for collecting any solid object left on the first side solid collector comprising:
at least one scraper, for scraping off solids left on the first side of the filter;
a driver, for driving the at least one scraper to move; and
a container, for storing the solids after being scrapped off the first side of the filter; and

an extrusion unit, for pressing the absorption layer so as to squeeze liquid containing in the absorption layer out of the same;
wherein, the first side is provided for a solid-liquid mixture to be placed thereon for allowing the liquid containing in the solid-liquid mixture to flow into the absorption layer through the filtration layer while enabling any solid object in the solid-liquid mixture to be filtered out and thus left on the first side.

2. The filtration dehydration apparatus of claim 1 , wherein the supporting structure is arranged piercing through the filter.

3. The filtration dehydration apparatus of claim 1 , wherein the filtration layer is formed with a plurality of first holes while allowing each first hole to be formed in a diameter smaller than the particle size of any solid existed in the solid-liquid mixture, and the absorption layer is formed with a plurality of second holes, while allowing each second hole to be formed in a diameter larger than that of the first hole.

4. The filtration dehydration apparatus of claim 1 , further comprising:
a feed hopper unit, configured with at least one hopper and a sensor in a manner that each hopper is arranged to move in synchronization with the scraper corresponding thereto, and the sensor is arranged for enabling the same to detect the position of each of the at least one scraper so as to activate the at least one hopper for feeding the solid-liquid mixture to the first side of the filter accordingly.

5. The filtration dehydration apparatus of claim 1 , wherein the at least one scraper is driven to move in a direction parallel to a first direction while allowing the hopper corresponding thereto to move rear to the at least one scraper also in a direction parallel to the first direction, and simultaneously being controlled to feed the solid-liquid mixture to the first side of the filter when the sensor detects the scrapping of the at least one scraper through the first side of the filter.

6. The filtration dehydration apparatus of claim 1 , wherein the extrusion unit is substantially a roller device that is arranged on the second side of the filter, and composed of a plurality of rollers and a driver in a manner that the plural rollers are arranged for allowing the same to be driven to rotate in synchronization by the driver while engaging to the second side of the filter for squeezing the absorption layer.

7. The filtration dehydration apparatus of claim 1 , wherein the supporting structure is further comprised of a movable pressure plate, and the extrusion unit is substantially a magnetic spring device that is composed of a plurality of magnetic springs and a driver in a manner that each magnetic spring is further configured with a disengaging height and an extrusion height, and the plural magnetic springs are arranged for allowing the same to be driven to raise/lower in synchronization by the driver while enabling each magnetic spring to engage and push the pressure plate to press on and squeeze the absorption layer when each magnetic spring is being driven to reach the extrusion height corresponding thereto.

8. The filtration dehydration apparatus of claim 1 , wherein the extrusion unit is substantially a first multi-stage extrusion unit, composed of a plurality of rollers; each of the plural rollers has a driving element that is eccentrically and pivotally mounted thereon, while allowing the plural driving elements to be mounted respectively to their corresponding rollers at different positions with respect to one another; each of the plural driving elements is coupled to a pressure plate by an end thereof that is opposite to an end thereof coupling to its corresponding roller; and the plural rollers are arranged for allowing the same to be driven to rotate by a driver so as to enable the plural pressure plates to be brought along to move asynchronously and reciprocatingly upward and downward between a disengaging height and an extrusion height, and thereby, enabling the pressure plates to press on and squeeze the absorption layer asynchronously and reciprocatingly when each pressure plate is being driven to reach the extrusion height corresponding thereto so as to achieve a multi-stage extrusion operation upon the absorption layer.

9. The filtration dehydration apparatus of claim 1 , wherein the extrusion unit is substantially a multi-stage extrusion unit, composed of at least one roller; the at least one roller has a plurality of driving elements that are eccentrically and pivotally mounted on the roller; each of the plural driving elements is coupled to an engaging part by an end thereof that is opposite to an end thereof coupling to the roller; the engaging part is further configured with a drive shaft that is further connected to a pressure plate; and the at least one roller is arranged for allowing the same to be driven to rotate by a driver so as to enable the plural driving elements to be brought along to rotate accordingly, and thereby, brought along their corresponding pressure plates to move asynchronously and reciprocatingly upward and downward between a disengaging height and an extrusion height so as to press on and squeeze the absorption layer asynchronously and reciprocatingly when each pressure plate is being driven to reach the extrusion height corresponding thereto for achieving a multi-stage extrusion operation upon the absorption layer.

10. The filtration dehydration apparatus of claim 9 , wherein the apparatus comprises two driving elements, being eccentrically arranged at two opposite sides of the roller.

11. A filtration dehydration apparatus, comprising:
a filter, composed of a filtration layer and an absorption layer while allowing a surface of the filtration layer that is orientated opposite to the absorption layer to be a first side of the filter, and allowing a surface of the absorption layer that is orientated opposite to the filtration layer to be a second side of the filter;
a supporting structure, for supporting and fixedly securing the filter;
a solid collector, for collecting any solid object left on the first side;
an extrusion unit, for pressing the absorption layer so as to squeeze liquid containing in the absorption layer out of the same; and
a feed hopper unit, configured with a plurality of hoppers that are electrically connected to a control switch to be used for controlling the activation of each of the plural hoppers for feeding the solid-liquid mixture to the first side of the filter accordingly;
wherein, the first side is provided for a solid-liquid mixture to be placed thereon for allowing the liquid containing in the solid-liquid mixture to flow into the absorption layer through the filtration layer while enabling any solid object in the solid-liquid mixture to be filtered out and thus left on the first side.
