Abstract

Improved filter vessel assemblies for filtering fluids in fluid systems (e.g., industrial and/or commercial systems) are provided. More particularly, the present disclosure provides for advantageous filter vessel assemblies that include a releasable locking assembly for a removable filter member (e.g., a filter bag). The present disclosure provides for improved systems/designs for easily securing and/or unsecuring removable filter members to or from a locking assembly of a filter vessel assembly. Improved, convenient, low-cost and/or effective systems and methods for easily securing and/or unsecuring removable filter members to or from a filter vessel assembly by utilizing advantageous locking assemblies associated with a supporting assembly or basket assembly of the filter vessel assembly are provided.

First claim

What is claimed is:

1. A filter vessel assembly comprising:
an elongated housing having an interior surface;
a supporting assembly disposed within the housing;
a removable filter member configured to be at least partially disposed within the supporting assembly;
a locking assembly including a first securing member, a second securing member and a locking member disposed within the housing;
wherein the locking member is movably secured to the first securing member, thereby allowing the locking member to be moved to a desired position;
wherein at least a portion of the first securing member is sized to rest upon at least a portion of the interior surface of the housing;
wherein the first securing member defines a central opening therethrough, the first securing member including a lower surface;
wherein at least a portion of the supporting assembly is configured to travel within the central opening of the first securing member to a position where an upper end of the supporting assembly mounts to at least a portion of the lower surface of the first securing member;
wherein at least a portion of the filter member is sized to rest upon at least a portion of the first securing member;
wherein at least a portion of the second securing member is configured to be positioned above at least a portion of the filter member resting upon the first securing member; and
wherein the movably secured locking member is configured to be moved to engage at least a portion of the locking member with at least a portion of at least one of the first and second securing member to releasably secure the filter member to the locking assembly.

2. The filter vessel assembly of claim 1 , wherein the housing includes an open end and at least one fluid inlet;
wherein the interior surface of the housing includes an intermediate interior surface that extends inwardly toward a center of the housing;
wherein at least the portion of the first securing member is sized to rest upon at least a portion of the intermediate interior surface of the housing; and
wherein the intermediate interior surface of the housing is positioned below the at least one fluid inlet relative to the open end of the housing.

3. The filter vessel assembly of claim 1 , wherein the housing includes an open end; and
further comprising a cover member removably mounted to the open end of the housing; and
wherein the cover member fluidically seals the open end of the housing when the cover member is removably mounted to the open end of the housing.

4. The filter vessel assembly of claim 3 , wherein the open end of the housing includes external threads, the external threads having a non-threaded section that is configured to allow fluid to escape from the housing via the non-threaded section when the cover member is mounted to the open end of the housing, and at least one of: (i) the housing is over-pressurized, (ii) attempt is made to remove the cover member from the open end of the housing without de-pressurizing the housing, and (iii) the cover member is not fully secured to the housing and attempt is made to pressurize the housing.

5. A filter vessel assembly comprising
an elongated housing having an interior surface;
a supporting assembly disposed within the housing;
a removable filter member configured to be at least partially disposed within the supporting assembly;
a locking assembly including a first securing member, a second securing member and a locking member disposed within the housing;
wherein the locking member is movably secured to the first securing member, thereby allowing the locking member to be moved to a desired position;
wherein at least a portion of the first securing member is sized to rest upon at least a portion of the interior surface of the housing;
wherein at least a portion of the supporting assembly is configured to mount to at least a portion of the first securing member;
wherein at least a portion of the filter member is sized to rest upon at least a portion of the first securing member;
wherein at least a portion of the second securing member is configured to be positioned above at least a portion of the filter member resting upon the first securing member;
wherein the movably secured locking member is configured to be moved to engage at least a portion of the locking member with at least a portion of at least one of the first and second securing member to releasably secure the filter member to the locking assembly;
wherein the housing includes an open end; and
further comprising a cover member removably mounted to the open end of the housing;
wherein the cover member fluidically seals the open end of the housing when the cover member is removably mounted to the open end of the housing;
wherein the open end of the housing includes a groove that extends around a perimeter of the open end of the housing, the groove defined by a lower wall, an outer wall and an inner wall, the inner wall including at least one slot configured to allow fluid to drain from the outer wall to a center of the housing;
wherein the lower wall extends from the outer wall to the inner wall at a downward angle between about 1° to about 10° toward the center of the housing.

6. The filter vessel assembly of claim 5 , wherein the groove is configured to house a gasketing material;
wherein the cover member is configured to create a sealing surface with the gasketing material housed in the groove of the open end of the housing when the cover member is mounted to the open end of the housing; and
wherein internal pressure forces the gasketing material toward the outer wall when the cover member is mounted to the open end of the housing.

7. The filter vessel assembly of claim 1 , wherein the housing includes first and second fluid inlets, first and second fluid outlets, at least one fluid inlet boss, and first and second fluid outlet bosses;
wherein the first fluid inlet includes a removable cap that fluidically seals the first fluid inlet and the first fluid outlet includes a removable cap that fluidically seals the first fluid outlet; and
wherein the second fluid inlet includes a hollow connector member and the second fluid outlet includes a hollow connector member.

8. The filter vessel assembly of claim 7 , wherein the first and second fluid inlets and the at least one fluid inlet boss are positioned at an upper end of the housing;
wherein the first and second fluid outlets and the first and second fluid outlet bosses are positioned at a lower end of the housing;
wherein the at least one fluid inlet boss is positioned about 90° from the first and second fluid inlets on the housing; and
wherein the first and second fluid outlet bosses are positioned about 90° from the first and second fluid outlets on the housing.

9. The filter vessel assembly of claim 1 , wherein the supporting assembly includes an open end having a collar member;
wherein the collar member is substantially annular and extends outwardly from and around a perimeter of the open end of the supporting assembly; and
wherein at least a portion of the collar member is configured to mount to at least a portion of the first securing member.

10. The filter vessel assembly of claim 1 , wherein the filter member is a removable filter bag that includes an open end and a sealing member;
wherein the sealing member of the filter member is positioned proximal the open end of the filter member; and
wherein at least a portion of the sealing member is sized to rest upon at least a portion of the first securing member.

11. The filter vessel assembly of claim 1 , wherein the interior surface of the housing includes at least one inner protrusion that is configured to guid
