Abstract

Disclosed are various embodiments of a drum treatment assembly that is configured to remote waste fluid contained within a drum. In one example, among other, drum treatment assembly includes a drum lid with an aperture and a treatment assembly that is suspended from the aperture in the drum lid. The treatment assembly can include a motor enclosure for a motor and a motor coupler. The treatment assembly can also include a skimmer assembly that is attached to the motor coupler. The skimmer assembly can include a belt system for moving a belt along a longitudinal axis of a drum and a trough. The trough can comprise a belt scraper and a trough aperture, in which the belt scraper is configured to remove waste attached to the belt. The trough aperture is configured to connect to a drainage tube for draining the waste out of the drum.

First claim

Therefore, the following is claimed:

1 . A drum treatment assembly, comprising:
a drum; and a treatment assembly that is suspended within the drum, the treatment assembly comprising:
a skimmer assembly comprising:
a belt system for moving a belt along a longitudinal axis of the drum; and
a trough that includes a belt scraper and a trough aperture, wherein the belt scraper is configured to remove waste attached to the belt, and the trough aperture is configured to be connected to a drainage tube;

a heating element that extends along the longitudinal axis of the drum; and
a float system that extends the longitudinal axis of the drum, wherein the float system is configured to detect a fluid level in the drum.

2 . The drum treatment assembly of claim 1 , wherein the float system further comprises:
a first sensor that is positioned a first distance along a rod, wherein the first sensor is configured to detect the fluid level at the first distance; and a second sensor that is positioned a second distance along the rod, wherein the second sensor is configured to detect the fluid level at the second distance.

3 . The drum treatment assembly of claim 1 , wherein the treatment assembly further comprises a temperature sensor that is configured to measure a temperature of the fluid in the drum.

4 . The drum treatment assembly of claim 1 , wherein the trough comprises a side surface that includes the trough aperture, wherein the side surface is angled with respect to a bottom surface of the trough aperture.

5 . The drum treatment assembly of claim 1 , wherein the belt scraper is formed from an outer edge of the side surface of the trough.

6 . The drum treatment assembly of claim 1 , wherein the treatment assembly further comprises a motor enclosure that is attached to the skimmer assembly by way of a motor coupler.

7 . The drum treatment assembly of claim 1 , wherein the treatment assembly is suspended by a drum lid.

8 . A drum top assembly, comprising:
a drum; and a treatment assembly that is suspended within the drum, the treatment assembly comprising:
a motor enclosure that include a motor and a motor coupler; and
a skimmer assembly that is attached to the motor coupler, the skimmer assembly comprising:
a belt system for moving a belt along a longitudinal axis of the drum; and
a trough that includes a belt scraper and a trough aperture, wherein the belt scraper is configured to remove waste attached to the belt, wherein the trough aperture is configured to be connected to a drainage tube for draining the waste out of the drum.

9 . The drum top assembly of claim 8 , wherein the skimmer assembly further comprises a first pulley attached to the motor coupler and a second pulley spaced away from a drum lid along the longitudinal axis of the drum.

10 . The drum top assembly of claim 8 , wherein the trough aperture is situated in a bottom surface of the trough.

11 . The drum top assembly of claim 8 , wherein the belt scraper is an outer edge of a side surface.

12 . The drum top assembly of claim 11 , wherein the side surface is slanted with respect to a bottom surface of the trough.

13 . The drum top assembly of claim 8 , further comprising a controller that is data communication with the skimmer assembly, wherein the controller is configured to initiate operation of the skimmer assembly on a periodic interval.

14 . The drum top assembly of claim 8 , wherein the drainage tube connects to an inner fitting of the drum.

15 . The drum top assembly of claim 8 , wherein the treatment assembly is suspended by being situated on a recessed platform that extends along a perimeter of the aperture in the drum lid.

16 . The drum top assembly of claim 8 , wherein the belt scraper is positioned at a height that is between a first pulley and a second pulley of the belt system.

17 . A drum top assembly, comprising:
a drum; and a treatment assembly that is suspended within the drum, the treatment assembly comprising:
a float system that extends along a longitudinal axis of the drum, wherein the float system is configured to detect a fluid level in the drum, wherein the float system comprising:
a first sensor that is positioned at a first depth in the drum, wherein the first sensor is configured to detect the fluid level at the first depth; and
a second sensor that is positioned at a second depth in the drum, wherein the second sensor is configured to detect the fluid level at the second depth.

18 . The drum top assembly of claim 17 , wherein at least one of the first sensor or the second sensor comprises a magnetic switch that opens or closes based on a movement of a float component.

19 . The drum top assembly of claim 17 , further comprising a temperature sensor that is configured to detect a temperature of a fluid in the drum.

20 . The drum top assembly of claim 17 , wherein the float system is in data communication with a controller.

21 . The drum top assembly of claim 8 , further comprising a controller that is configured to at least:
determine a cycle time of operational use for the treatment assembly; and transmit a service notification to a remote computing device based at least in part on the cycle time meeting a service threshold.

22 . The drum top assembly of claim 8 , further comprising a controller that is configured to at least:
determine a cycle time of operational use for the treatment assembly; and detect a decline in the cycle time based at least in part on a history of cycle time; and transmit a decline notification to a remote computing in response to detecting the decline in the cycle time.
