Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a detachable bar screen filter assembly for wastewater treatment. Background Technology
[0002] In the wastewater treatment process, bar screen filter components are key equipment for intercepting suspended impurities in water (such as plastic fragments, fibers, silt, and large particles), and can protect downstream treatment units (such as water pumps and reactors) from clogging or damage.
[0003] Based on the above, the inventors have discovered the following problems: Traditional grids are mostly fixed welded structures. When the grid surface is blocked or worn, it is necessary to disassemble it as a whole or stop the machine for cleaning, which is cumbersome and time-consuming.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a detachable bar filter assembly for wastewater treatment, in order to achieve a more practical value. Utility Model Content
[0005] The purpose of this utility model is to provide a detachable bar screen filter assembly for wastewater treatment, so as to solve the problem mentioned in the background art that traditional bar screens are mostly fixed welded structures, and when the bar screen surface is blocked or worn, the whole assembly needs to be disassembled or the machine needs to be stopped for cleaning.
[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0007] A detachable wastewater treatment bar filter assembly includes a main body and a filter mechanism. The main body includes a mounting frame with mounting bases fixedly installed at both ends. A U-shaped slot is provided inside the mounting frame. A fixing block is provided on the outer upper end of each mounting frame, and a stop block is installed at the upper end of each fixing block. A pair of L-shaped slots are mirror-imagely provided on the outer upper end of each mounting frame. A movable groove is provided on the inner side of each fixing block, and a pair of L-shaped inserts are slidably installed inside each movable groove. Each pair of L-shaped inserts is mirror-imagely arranged, and the L-shaped inserts are inserted into the L-shaped slots. The filter mechanism includes a fixed frame that is slidably inserted into the U-shaped slots. The bottom end of the stop block abuts against the top end of the fixed frame. Several fixed bar screens are fixedly installed on one side of the fixed frame.
[0008] Furthermore, a bidirectional screw is rotatably connected to the bottom of the fixed block, and both ends of the bidirectional screw are threaded with sliders, with each pair of sliders being fixedly connected to each pair of L-shaped inserts.
[0009] The beneficial effect of adopting the above-mentioned further solution is that the rotation of the bidirectional screw drives the slider to move in opposite directions, so that the L-shaped plug can extend and retract synchronously, realize the quick insertion or separation with the L-shaped slot, control the fixing block to fix the fixing frame, and make the operation highly efficient.
[0010] Furthermore, each of the bidirectional screws is fitted with a worm gear at its center, and each of the fixed blocks is rotatably connected to a worm, with the worm and the worm gear meshing with each other.
[0011] The beneficial effect of adopting the above-mentioned further solution is that the meshing transmission between the worm and the worm wheel converts the rotational motion of the worm into the rotation of the bidirectional screw. By utilizing the self-locking property of the worm and the worm wheel, the L-shaped plug and the L-shaped slot are stably connected, preventing loosening.
[0012] Furthermore, one end of each worm gear extends outward through the fixing block and is fitted with a rotating wheel.
[0013] The advantages of adopting the above-mentioned further solution are that the rotary wheel facilitates manual rotation of the worm gear, saving effort and making operation convenient. The worm gear drives the bidirectional screw to rotate, realizing the rapid adjustment of the L-shaped plug and improving the efficiency of disassembly and assembly.
[0014] Furthermore, the upper and lower ends of the fixed frame are provided with sliding grooves, and movable strips are slidably installed inside the sliding grooves. Several movable grids are fixedly installed between a pair of movable strips.
[0015] The beneficial effect of adopting the above-mentioned further solution is that the moving bar slides along the chute, causing the moving grid and the fixed grid to be misaligned, the grid spacing can be adjusted, adapting to the filtration needs of impurities of different sizes, and enhancing the versatility of the equipment.
[0016] Furthermore, a pair of locking nuts are threadedly connected to the upper outer side of the fixing frame, and one end of the locking nut passes through the sliding groove and abuts against the outer side of the moving bar.
[0017] The beneficial effect of adopting the above-mentioned further solution is that the locking nut presses against the moving strip, fixes the position of the moving screen, prevents the screen spacing from changing due to water flow impact during filtration, ensures stable filtration effect, and facilitates quick fixation after adjusting the spacing.
[0018] Furthermore, a number of reinforcing rods are fixedly installed inside the fixed frame on one side of the moving grid, and the reinforcing rods are evenly distributed between each other.
[0019] The beneficial effects of adopting the above-mentioned further solutions are that the reinforcing rod enhances the structural strength of the fixing frame, disperses the impact force of water flow on the fixed and moving screens, avoids deformation after long-term use, and extends the service life of the filtration mechanism.
[0020] Furthermore, the mounting bracket, mounting base, fixing bracket, fixed grid, moving grid, and reinforcing rod are all made of stainless steel.
[0021] The beneficial effects of adopting the above-mentioned further solutions are that the mounting frame, mounting base, fixing frame, fixed grid, moving grid and reinforcing rod are all made of stainless steel. Stainless steel is resistant to wastewater corrosion, has strong oxidation resistance, adapts to the humid and complex wastewater treatment environment, reduces structural damage caused by rust, ensures long-term stable operation of components, and reduces maintenance costs.
[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: The main body of the detachable wastewater treatment bar filter assembly has a U-shaped slot for easy insertion and removal of the filter mechanism's fixing frame. The L-shaped plug and L-shaped slot cooperate to fix the fixing frame, and the abutment block enhances the stability of the fixing frame inside the mounting frame. The fixed bar intercepts impurities in the wastewater. The overall structure enables quick disassembly and assembly of the filter mechanism, facilitating cleaning or replacement, improving wastewater filtration efficiency and maintenance convenience. The worm gear and worm wheel meshing drive converts the rotational motion of the worm gear into the rotation of a bidirectional screw. The self-locking property of the worm gear and worm wheel ensures stable insertion of the L-shaped plug and L-shaped slot, preventing the loose moving strip from sliding along the slide groove and causing the moving bar and fixed bar to misalign. The bar spacing can be adjusted to adapt to the filtration needs of impurities of different sizes, enhancing the equipment's versatility. The locking nut abuts against the moving strip, fixing the position of the moving bar and preventing changes in the bar spacing due to water flow impact during filtration, ensuring stable filtration effect and facilitating quick fixation after adjusting the spacing.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figure 1 - Figure 5 A bidirectional screw 110 is rotatably connected to the bottom of the fixed block 104. Both ends of the bidirectional screw 110 are threaded with sliders 112.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Please see Figure 1 - Figure 5The fixed frame 201 has sliding grooves 204 at both its upper and lower ends. Moving bars 205 are slidably installed inside each sliding groove 204. Several movable grids 206 are fixedly installed between a pair of moving bars 205. A pair of locking nuts 203 are threaded to the upper outer side of the fixed frame 201. One end of the locking nut 203 passes through the sliding groove 204 and abuts against the outer side of the moving bar 205. Several reinforcing rods 207 are fixedly installed inside the fixed frame 201 on one side of the movable grids 206, and are evenly distributed. The mounting frame 101, mounting base 102, fixed frame 201, fixed grids 202, movable grids 206, and reinforcing rods 207 are all made of stainless steel. The moving bars 205 slide along the sliding grooves 204, causing the movable grids 206 to be misaligned with the fixed grids 202, thus adjusting the grid spacing. To adapt to the filtration needs of impurities of different sizes and enhance the versatility of the equipment, the locking nut 203 abuts against the moving bar 205, fixing the position of the moving bar 206. This prevents changes in the bar spacing due to water flow impact during filtration, ensuring stable filtration performance and facilitating quick fixation after spacing adjustment. The reinforcing rod 207 enhances the structural strength of the fixing frame 201, disperses the impact force of water flow on the fixed bar 202 and the moving bar 206, avoids deformation after long-term use, and extends the service life of the filter mechanism 2. The mounting frame 101, mounting base 102, fixing frame 201, fixed bar 202, moving bar 206, and reinforcing rod 207 are all made of stainless steel. Stainless steel is resistant to wastewater corrosion, has strong oxidation resistance, adapts to the humid and complex wastewater treatment environment, reduces structural damage caused by rust, ensures long-term stable operation of components, and reduces maintenance costs.
[0035] Specifically, the working principle of this detachable wastewater treatment bar filter assembly is as follows: During use, the fixing frame 201 is inserted into the U-shaped slot 103 of the mounting frame 101. Rotating the rotating wheel 105 drives the worm gear 109 to mesh with the worm wheel 111, causing the bidirectional screw 110 to rotate. The slider 112 drives the L-shaped insert 108 to insert into the L-shaped slot 113, which, in conjunction with the abutment block 106, fixes the fixing frame 201. The distance between the moving bar 206 and the fixed bar 202 is adjusted by the moving strip 205 within the sliding groove 204. The locking nut 203 is tightened to fix the bar, and the reinforcing rod 207 enhances the structural strength. During filtration, impurities in the wastewater are intercepted. During disassembly, rotating the rotating wheel 105 in the opposite direction separates the fixing block 104 from the mounting frame 101, allowing the fixing frame 201 to be removed for cleaning of the fixed bar 202 and the moving bar 206. This achieves rapid disassembly and assembly of the bar and efficient filtration.
