[0005] A novel slurry filter device fixed bolster, comprising a fixed bolster bottom plate, two filter fixing blocks and two filter fixing block bases, wherein the filter fixing block bases are fixed on the fixed bolster bottom plate by bolts or screws, the filter fixing blocks are provided with sliding groove structures that are inserted and fixed with the filter fixing block bases, and the two filter fixing blocks are designed to be opened and mutually clamped.

[0006] Preferably, a first screw hole is arranged on the fixed bolster bottom plate, a second screw hole matched with the first screw hole is arranged on the filter fixing block base, and the second screw hole and the first screw hole are fixed by bolts or screws.

[0007] Preferably, a through clamping groove is arranged on the filter fixing block, and the filter fixing block base is inserted into the clamping groove to fix it.

[0008] Preferably, a bottom support plate is fixed at the lower end of the filter fixing block base to support and hold the bottom of the filter fixing block.

[0009] Preferably, a second protrusion is fixedly provided on one of the filter fixing clips, and two first protrusions are fixedly provided on the other, with a locking position formed between the first protrusions for the second protrusion to be engaged. The first protrusion has a through first pin hole, and the second protrusion has a through second pin hole. It also includes a fixing pin with a pin limiting block for being inserted into the second pin hole and the fixing pin for fixing.

[0010] Preferably, the upper ends of the pin limiting block and the first protrusion are magnetically fixed together.

[0011] The advantages and positive effects of this utility model are: the new filter bracket is simple to operate, easy to disassemble and assemble, and improves work efficiency. Attached Figure Description
