## Abstract

A belt press filter belt changing assembly that includes two upright members, a wrap bar, a dowel rod, and a means of temporarily affixing the assembly to a belt press filter. The belt press filter changing assembly facilitates rapid, efficient, and safe changing of the belt press filter's continuous belts while requiring less personnel using less physical exertion than current solutions.

## Claims

### Claim 1

A belt changing assembly for a belt press filter comprising:
two upright members, each upright member including a wrap bar housing member, a dowel rod housing member, and a press-mating member that further includes a joining feature;
a wrap bar including a handle end, a distal end, and a cylindrical portion between the handle end and the distal end, the cylindrical portion including two embedded zipper mating members; and
a dowel rod.

### Claim 2 (depends on 1)

The belt changing assembly of claim 1, wherein the wrap bar is comprised of at least a first bar portion and a second bar portion, wherein the first bar portion and the second bar portion can be removeably coupled together, and wherein the dowel rod is comprised of at least a first dowel portion and a second dowel portion, wherein the first dowel portion and the second dowel portion are removeably coupled.

### Claim 3 (depends on 1)

The belt changing assembly of claim 1 wherein the handle end is hinged.

### Claim 4 (depends on 1)

The belt changing assembly of claim 1 wherein cylindrical portion includes two upright interface features, which are configured to rotationally interact with the wrap bar housing member of the respective upright member.

### Claim 5 (depends on 1)

The belt changing assembly of claim 1 wherein the dowel rod includes two upright interface features, which are configured to rotationally interact with the dowel rod housing member of the respective upright member.

### Claim 6 (depends on 1)

The belt changing assembly of claim 1 wherein the interface features are removeable from said cylindrical portion.

### Claim 7 (depends on 1)

The belt changing assembly of claim 1 wherein the handle end further comprises a removeable handle configured to couple to said handle end.

### Claim 8

A belt changing assembly, comprising:
at least one upright member, wherein said upright member has a wrap bar housing member, a dowel rod housing member, and a press mating member;
a wrap bar, wherein said wrap bar has a handle end, a distal end, and a cylindrical portion between said handle end and distal end; and a dowel rod.

### Claim 9 (depends on 6)

The belt changing assembly of claim 6, wherein said belt changing assembly comprises two upright members.

### Claim 10 (depends on 7)

The belt changing assembly of claim 7, wherein said press mating member further includes a joining feature configured to engage a portion of a belt press filter.

### Claim 11 (depends on 8)

The belt changing assembly of claim 8, wherein said handle end is coupled to said cylindrical portion by a hinged feature configured to allow said handle to have a low profile during operation of the assembly.

### Claim 12 (depends on 9)

The belt changing assembly of claim 9, wherein said cylindrical portion further comprises at least one embedded zipper mating members configured to interface with a belt.

### Claim 13 (depends on 10)

The belt changing assembly of claim 10, wherein the cylindrical portion of said wrap bar further includes an upright interface feature near said handle end and an upright interface feature near said distal end, wherein each upright interface features is configured to rotationally interact with the respective wrap bar housing member of said upright member.

### Claim 14 (depends on 11)

The belt changing assembly of claim 11, wherein said dowel bar further includes an upright interface feature near each end of said dowel bar.

### Claim 15 (depends on 11)

The belt changing assembly of claim 11, wherein said upright interface feature is removeable.

### Claim 16

A method for changing a belt of a belt filter press comprising:
providing a belt changing assembly having a mating member, a dowel rod having a replacement belt wherein the replacement belt has a first zipper member and a second zipper member, and a wrap bar;
locating a zipper portion of the belt on the belt filter press, wherein the belt has a first zipper member and a second zipper member;
removing a joining wire from the zipper portion rendering the belt discontinuous;
coupling the belt changing assembly to the belt press; coupling the first zipper member of the belt to the wrap bar and coupling the second zipper member of the belt to the first zipper member of the replacement belt;
rotating the wrap bar, thereby removing the belt onto the wrap bar and installing the replacement belt from the dowel rod;
decoupling the replacement belt from the belt;
joining the first and second zipper members of the replacement belt using a joining wire, thereby making the replacement belt continuous on the belt filter press; and
removing the belt changing assembly from the belt press.

### Claim 17 (depends on 16)

The method of claim 16, wherein said belt changing assembly comprises two upright members, each upright member including a wrap bar housing member, a dowel rod housing member, and a press-mating member having a joining feature.

### Claim 18 (depends on 17)

The method of claim 17, wherein the wrap bar includes a handle end, a distal end, and a cylindrical portion between the handle end and the distal end.

### Claim 19 (depends on 18)

The method of claim 18, wherein the cylindrical portion includes at least one embedded zipper mating members configured to be coupled to the belt zipper members.

### Claim 20 (depends on 16)

The method of claim 16, wherein the belt press filter changing assembly is removed prior to joining the first and second zipper members of the replacement belt.
