Technical Field
[0001] This utility model relates to the field of pulp mill filter screens, and in particular to a detachable and easy-to-clean pulp mill filter screen. Background Technology
[0002] The grinding mill is a novel stainless steel wet grinding equipment used for the wet grinding of grains such as rice, soybeans, corn, and potatoes, as well as for the wet grinding of certain materials in the pharmaceutical, sugar, and food industries. After pretreatment such as cleaning and soaking, the material enters the mill through the hopper. Under centrifugal force, it enters between the relatively moving upper and lower grinding discs. Due to the combined effects of mutual impact and compression of the material, and the shearing and tearing action of the grinding discs, the material is ground from the inside out and from coarse to fine along the plane of the grinding discs, achieving the grinding purpose.
[0003] Traditional grinder filters require the grinding wheel and screen frame to be disassembled for installation and washing. However, disassembly and reinstallation can disrupt the dynamic balance of the machine, causing it to vibrate.
[0004] Therefore, it is necessary to propose a detachable and easy-to-clean grinder filter to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A detachable and easy-to-clean pulp mill filter screen includes a filter screen body. The top two sides of the filter screen body are symmetrically and movably connected with first steel wire strips, and the bottom two sides of the filter screen body are symmetrically and movably connected with second steel wire strips. The top and bottom sides of the first steel wire strips are symmetrically provided with locking holes, and the inner cavity of the locking holes is movably connected with a first quick-release block and a second quick-release block.
[0008] Preferably, a first shrinkage groove is symmetrically formed at the center of the opposite side of the inner cavity of the locking edge hole on both sides, and a second shrinkage groove is symmetrically formed at both ends of the inner cavity of the locking edge hole on both sides. The first quick-release block and the second quick-release block are both movably connected in the inner cavity of the locking edge hole. The first steel wire pressure strip and the second steel wire pressure strip are respectively connected to the second quick-release block at the top and bottom. The first steel wire pressure strip is movably connected to the top of the filter screen body, and the second steel wire pressure strip is movably connected to the bottom of the filter screen body. The diameter of the first steel wire pressure strip and the second steel wire pressure strip is larger than the diameter of the top and bottom of the inner cavity of the pulper where the filter screen body is installed.
[0009] Preferably, the side of the first quick-release block is a first inclined side, and the side of the second quick-release block is a second inclined side, and the first quick-release block and the second quick-release block are attached to each other through the first inclined side and the second inclined side.
[0010] Preferably, a first shrink block is installed on the side of the first quick-release block near the filter body, a first fixing rod is installed in the inner cavity of the first shrink groove, a first quick-release spring is wound around the outer wall of the first fixing rod, and the first shrink block is movably connected in the inner cavity of the first shrink groove and sleeved on the outer wall of the first fixing rod.
[0011] Preferably, the second quick-release block has second shrink blocks symmetrically installed at both ends, the second shrink groove has a second fixing rod installed in the inner cavity of the second shrink groove, the outer wall of the second fixing rod is wound with a second quick-release spring, and the second shrink block is movably connected in the inner cavity of the second shrink groove and sleeved on the outer wall of the second fixing rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. This detachable and easy-to-clean pulp refiner filter screen uses a first and second steel wire clamping strip, which are larger than the diameter of the pulp refiner, to hold the filter screen body in place within the pulp refiner's inner cavity after the filter screen body is installed. This improves the efficiency of disassembling and assembling the filter screen body and avoids the common step of removing the grinding wheel and screen frame together when disassembling the filter screen in a pulp refiner.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figures 1-4As shown, a detachable and easy-to-clean pulper filter screen includes a filter screen body 1. First steel wire strips 7 are symmetrically and movably connected to both sides of the top of the filter screen body 1, and second steel wire strips 8 are symmetrically and movably connected to both sides of the bottom of the filter screen body 1. Locking holes 2 are symmetrically opened at the top and bottom of both sides of the first steel wire strips 7. A first quick-release block 5 and a second quick-release block 6 are movably connected within the inner cavity of the locking holes 2. A first shrinkage groove 3 is symmetrically opened at the center of opposite sides of the inner cavity of the two locking holes 2. Second shrinkage grooves 4 are symmetrically opened at both ends of the inner cavity of the two locking holes 2. The first quick-release block 5 and the second quick-release block 6 are both movably connected within the inner cavity of the locking holes 2. The side of the first quick-release block 5 is a first inclined edge 9, and the side of the second quick-release block 6 is a second inclined edge 10. The first quick-release block 5 and the second quick-release block 6 are mutually fitted together through the first inclined edge 9 and the second inclined edge 10. A first shrinkage block 11 is installed on the side of the first quick-release block 5 closest to the filter screen body 1. A first fixing rod 1 is installed within the inner cavity of the first shrinkage groove 3. 2. A first quick-release spring 13 is wound around the outer wall of the first fixed rod 12. A first retractable block 11 is movably connected in the inner cavity of the first retractable groove 3 and sleeved on the outer wall of the first fixed rod 12. Second retractable blocks 14 are symmetrically installed at both ends of the second quick-release block 6. A second fixed rod 15 is installed in the inner cavity of the second retractable groove 4. A second quick-release spring 16 is wound around the outer wall of the second fixed rod 15. The second retractable block 14 is movably connected in the inner cavity of the second retractable groove 4 and sleeved on the outer wall of the second fixed rod 15. One end of the first quick-release spring 13 is installed in the inner cavity of the first retractable groove 3, and the other end of the first quick-release spring 13 is connected to the first retractable block 11. One end of the second quick-release spring 16 is connected to the second retractable block 14, and the other end of the second quick-release spring 16 is installed in the inner cavity of the second retractable groove 4. The second quick-release block 6 can only move laterally, and the first quick-release block 5 can only move vertically. The elastic force of the first quick-release spring 13 is at least twice the elastic force of the second quick-release spring 16.
[0024] By using a first steel wire clamping strip 7 and a second steel wire clamping strip 8, which are larger than the diameter of the pulper, after the filter body 1 is installed in its inner cavity, the first steel wire clamping strip 7 and the second steel wire clamping strip 8 can hold the filter body 1 in the inner cavity of the pulper. Based on this, the efficiency of disassembling and assembling the filter body 1 can be improved, avoiding the common step of removing the grinding wheel and screen frame together when removing the filter screen in a pulper. It can quickly disassemble and maintain the filter body 1 from the pulper. By using the first quick-release spring 13, the first quick-release block 5 can be lifted upward by the first contraction block 11, in conjunction with the first quick-release spring 13.

Through the second fixed rod 15 and the second shrink block 14, the second quick-release block 6 can only move laterally. Therefore, the first steel wire pressure strip 7 and the second steel wire pressure strip 8 can be expanded outward through the second quick-release block 6. Based on this, the filter screen body 1 can be stuck in the pulper. When the filter screen body 1 needs to be removed, press the first quick-release block 5. Through the second quick-release spring 16, the first steel wire pressure strip 7 and the second steel wire pressure strip 8 can be reset through the second quick-release block 6.
[0025] It should be noted that this utility model is a detachable and easy-to-clean pulp refiner filter. When in use, press the first quick-release block 5 so that the first wire pressure strip 7 and the second wire pressure strip 8 can retract inward. After placing the filter body 1 in a suitable position on the pulp refiner, release the first quick-release block 5. The first quick-release spring 13 drives the first quick-release block 5 to move through the first retraction block 11. The first quick-release block 5 contacts the second inclined side 10 on the side of the second quick-release block 6 through the first inclined side 9, so that the second quick-release block 6 can drive the first wire pressure strip 7 and the second wire pressure strip 8 to expand outward. At this time, the filter body 1 can be locked in the inner cavity of the pulp refiner.
