Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of chemical production, and in particular relates to a chemical production filtering device. Background Art
[0002] Filtration is required in some chemical production processes. The purpose of filtration is to remove impurities such as solid particles and suspended matter generated during the production process in order to obtain pure products or enable subsequent reactions and processing to proceed smoothly.
[0003] For example, a Chinese patent with announcement number CN220237907U discloses a chemical filtering device for chemical production, including a main body mechanism, a lifting mechanism and a control mechanism, wherein the lifting mechanism is located at the inner end of the main body mechanism, and the control mechanism is located at the front end of the main body mechanism, wherein the main body mechanism includes a body, a bottom plate, a support rod, a rear support frame, a front support frame, a limit table and a top plate, wherein the bottom plate is fixedly mounted at the lower end of the body, the support rod is fixedly mounted at the lower end of the bottom plate, the rear support frame is fixedly mounted at the rear end of the upper end of the body, the front support frame is fixedly mounted at the front end of the upper end of the body, and the limit table is fixedly mounted at the inner end of the body. The chemical filtering device for chemical production, when the filter plate is to be replaced, the filter plate is taken out through the upper part of the filtering device, so that the outer end of the filtering device does not need to be provided with a disassembly port, thereby avoiding water leakage caused by poor sealing, and improving the practicality of the device.
[0004] The above patent has the following problems:
[0005] This patent has some shortcomings when in use, such as: when the device lifts the filter plate, the filter plate will shake to a certain extent. During the shaking process, impurities on the filter plate may fall from the filter plate, causing the impurities to fall into the main body. Moreover, when the filter plate in the device is only placed in the main body, if a large amount of wastewater is poured in at one time, a large amount of wastewater will flow in at the same time, causing the filter plate to shake, which will cause some wastewater to leak out from the side of the filter plate. Moreover, a large amount of wastewater will flow in at the same time, which will exceed the processing capacity of the filter plate, resulting in insufficient filtration, and solid impurities cannot be effectively intercepted, reducing the filtration effect and quality. In view of this, we propose a chemical production filtration device. Utility Model Content
[0006] The purpose of the utility model is to provide a chemical production filtering device to solve the problems raised in the above background technology.
[0007] In view of this, the utility model provides a chemical production filtering device, comprising:
[0008] A filter box, a liquid storage barrel is fixedly installed on the top of the filter box, a water pipe is fixedly installed on the top of the inner cavity of the filter box, a connecting pipe is fixedly installed on the bottom of the liquid storage barrel, the bottom end of the connecting pipe passes through the top of the filter box and is fixed and connected with the water pipe, a plurality of through pipes are fixedly installed on the bottom of the water pipe, and a valve is rotatably installed on the connecting pipe and located between the liquid storage barrel and the filter box;
[0009] Two protection frames, both of which are plugged and installed in the filter box and are located below a plurality of through pipes, a feed hopper is fixedly installed in the filter box and at the top of the two protection frames respectively, and a filter plate is clamped and installed in the protection frame;
[0010] A fixing component is located on the filter box and is used to fix the positions of the two protection frames.
[0011] In the present technical solution, when in use, the staff first puts the waste water into the liquid storage barrel, and then, the staff can turn and open the valve by hand, and then the waste water in the liquid storage barrel will enter the connecting pipe, and then, the waste water in the connecting pipe will enter the water pipe, and the waste water in the water pipe will be discharged from a plurality of through pipes and fall into one of the hoppers. Under the action of the water pipe and the plurality of through pipes, the waste water can enter one of the hoppers at a uniform speed, avoiding the situation where too much waste water is added at one time and causing insufficient filtration, and the hopper can play a role of convergence, so that the waste water can fall exactly into one of the hoppers. The wastewater is filtered on one of the filter plates and close to the center area thereof, so that some impurities remain on one of the filter plates, and some wastewater is prevented from flowing out from the side of the filter plate. After being filtered by one of the filter plates, the wastewater will fall into another feed hopper, and then the wastewater in the other feed hopper will flow into another filter plate for more detailed filtration, ensuring that the impurities and fine substances in the wastewater can be filtered out. During this process, the filter plate will not shake, and then the filtered wastewater will be discharged from the drain pipe at the bottom of the filter box;
[0012] When cleaning the impurities on the two filter plates, the fixing components are used to release the fixation of the two protective frames. Subsequently, the staff can pull the protective frame by hand to pull the protective frame together with the filter plate out of the filter box. After the protective frame together with the filter plate are pulled out of the filter box, the staff can take the protective frame to the designated cleaning location, and then remove the filter plate in the protective frame for cleaning. Under the action of the protective frame, the impurities on the filter plate will not fall off, thereby preventing the impurities on the filter plate from falling into the filter box or on the ground.
[0013] In the above technical solution, further, the fixing assembly includes:
[0014] A slide groove, which is opened in the filter box and located between two protective frames. A sliding rod is slidably installed in the slide groove. One end of the sliding rod passes through one side of the slide groove and extends to the outside and is fixedly installed with a U-shaped plate. Both ends of the U-shaped plate pass through one side of the filter box and extend into the corresponding protective frames respectively. The other end of the sliding rod is located in the slide groove and is provided with a tension spring.
[0015] In this technical solution, when cleaning impurities on the two filter plates, the staff pulls the U-shaped plate by hand, so that the U-shaped plate drives the sliding rod to move in the direction away from the tension spring. At this time, the tension spring will be subjected to the tension of the sliding rod and stretch until the two ends of the U-shaped plate are pulled out of the corresponding protective frames, so that the two protective frames are released.
[0016] In the above technical solution, further, the two ends of the U-shaped plate are slidably connected to one side of the filter box, and the two ends of the U-shaped plate are respectively plugged into the corresponding protective frame, and the two ends of the tension spring are respectively tightly welded to the other end of the sliding rod and the inner wall of the slide groove.
[0017] In the technical solution, it is ensured that both ends of the U-shaped plate can slide on the filter box; it is ensured that both ends of the U-shaped plate can be inserted into the corresponding protective frame; and it is ensured that the structure of the tension spring is stable when in use.
[0018] In the above technical solution, further, the bottom end of the connecting pipe is tightly welded to the water pipe, and the plurality of through pipes are all connected to the inner cavity of the water pipe.
[0019] In the technical solution, the structural stability between the connecting pipe and the water pipe is ensured; it is ensured that the wastewater in the water pipe can flow out from a plurality of through pipes, so that the feeding speed can be made more uniform.
[0020] In the above technical solution, further, the inner cavity of the feed hopper is in the shape of an inverted cone, and the cross-sectional size of the filter plate is equal to the cross-sectional size of the inner cavity of the filter box.
[0021] In the present technical solution, the inner cavity of the feed hopper has an inverted cone-shaped structure that can play a convergence role, so that the wastewater in the feed hopper can fall exactly on the filter plate and close to its central area, ensuring that the filter plate can filter the wastewater and the wastewater will not leak from the side of the filter plate.
[0022] In the above technical solution, further, the filtering accuracy of one of the filter plates is 100 μm-200 μm, and the filtering accuracy of the other filter plate is 1 μm-10 μm.
[0023] In this technical solution, it is ensured that the wastewater can be filtered cleanly.
[0024] The beneficial effects of the utility model are:
[0025] The chemical production filtering device ensures that wastewater can enter the filter box at a uniform speed through the cooperation between the liquid storage barrel, valve, protection frame, filter box, connecting pipe, water pipe, through pipe, filter plate, feed hopper and limit assembly, so that it can be filtered more fully by the two filter plates. Moreover, when the wastewater enters the filter box, the feed hopper can make the wastewater fall on the filter plate and close to the central area thereof, and the wastewater will not leak from the side of the filter plate. Moreover, when cleaning impurities on the filter plate, the protection frame can make personnel conveniently move the filter plate to a designated location for cleaning, and no impurities will fall out from the side of the filter plate during the movement.
