Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a filter component for treating chemical production wastewater. Background Technology

[0002] Chemical production wastewater refers to various types of wastewater generated during chemical production processes, mainly including process wastewater, cooling water, exhaust gas scrubbing water, equipment and site washing water, etc. To remove impurities from wastewater, improve water quality, protect the environment, and reduce costs, wastewater needs to be filtered, hence the use of a filter component for chemical production wastewater treatment.

[0003] To address this, patent CN214781094U discloses a filtration device for treating wastewater from sodium alginate production. The key technical features are: a filter box with an inlet pipe at the top and an outlet pipe at the bottom; a transverse groove on the side wall of the filter box, within which a filter plate is slidably connected; a connecting block on the inner side wall away from the groove, with a connecting groove for the filter plate to engage; sliding strips on both sides of the filter plate; and sliding grooves on the inner walls of both sides of the groove for the sliding strips to engage; a slot on the inner side wall of the groove away from the connecting block, with a limiting member slidably connected inside the slot to prevent the sliding strips from disengaging from the groove. The advantages of this invention are: when the filter plate needs to be replaced, simply release the limiting member from the sliding strips, allowing the filter plate to slide out of the groove and be disassembled and replaced, preventing filter plate blockage and ensuring the filtration effect of the filter box.

[0004] Although the filter device for treating sodium alginate production wastewater described above allows the filter plate to slide out of the horizontal groove and be disassembled and replaced, it is inconvenient to clean and prevent the filter screen from clogging, thus making it difficult to improve the filtration efficiency and resulting in low working efficiency during use. Utility Model Content

[0005] The purpose of this invention is to provide a filter assembly for treating chemical production wastewater, in order to solve the problem that existing filter assemblies for treating chemical production wastewater are inconvenient to clean.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a filter assembly for treating chemical production wastewater, including a filter box;

[0007] The filter box is fixed inside with an installation frame, and the installation frame is provided with a filter structure inside;

[0008] The filter box below the mounting frame is equipped with a cleaning structure. The cleaning structure includes a reciprocating screw installed inside the filter box. A movable seat is threaded to the outside of the reciprocating screw. A cleaning brush is fixed to the top of the movable seat. A sliding rod passes through one side of the movable seat. A drive motor is installed on the outer wall of the filter box at one end of the reciprocating screw.

[0009] A purification structure is provided on the top of the filter box.

[0010] When using this device, the cleaning structure facilitates clogging prevention, thereby improving the working efficiency of the filter assembly for treating chemical wastewater; the purification structure facilitates purification, thereby improving the applicability of the filter assembly for treating chemical wastewater; and the filtration structure facilitates filtration, thereby improving the ease of use of the filter assembly for treating chemical wastewater.

[0011] Preferably, a water inlet pipe is fixed to one side of the bottom of the filter box, a cover plate is provided at the top of the filter box, and a cover drain pipe is fixed to the top of the cover plate.

[0012] Preferably, one end of the reciprocating lead screw extends to the outside of the filter box and is fixedly connected to the output end of the drive motor. The slide rod and the movable seat form a sliding structure, and both ends of the slide rod are fixedly connected to the inner wall of the filter box. When the reciprocating lead screw rotates, it drives the movable seat to move. The movable seat moves outside the slide rod, preventing it from rotating with the reciprocating lead screw. The movable seat drives the cleaning brush to clean the bottom of the stainless steel filter screen. Under the action of the reciprocating lead screw, the cleaning brush cleans from one side of the bottom of the stainless steel filter screen to the other side, thereby preventing the stainless steel filter screen from clogging and effectively improving the filtration effect.

[0013] Preferably, the purification structure includes a first fixed frame, an activated carbon filter, a nylon filter, a chute, a sliding plate, and handles. The chute is located on both sides of the top of the filter box, and a sliding plate is installed inside each chute. The first fixed frame is fixed between adjacent sliding plates. A nylon filter is installed at the bottom of the first fixed frame, and an activated carbon filter is installed at the top of the first fixed frame. Handles are fixed on both sides of the top of the first fixed frame. The chute and sliding plate work together to move the first fixed frame into the filter box. The top of the handle abuts against the bottom of the cover plate to limit the movement of the first fixed frame inside the filter box.

[0014] Preferably, the slide plate and the filter box form a sliding structure through a sliding groove, and the top of the handle abuts against the bottom of the cover plate. By pulling the handle, the first fixing frame is moved to the outside of the filter box, allowing for cleaning of the activated carbon filter and the nylon filter. Under the action of the nylon filter and the activated carbon filter, suspended particulate matter, impurities, and solid particles in the chemical wastewater are effectively removed, while also adsorbing and removing harmful substances, thereby improving the cleanliness of the wastewater.

[0015] Preferably, the filter structure includes a second fixed frame, a locking block, a locking groove, a sealing ring, a rubber ring, a placement groove, and a stainless steel filter screen. The second fixed frame is disposed inside the mounting frame. Locking blocks are evenly fixed on both sides of the bottom of the second fixed frame. Locking grooves are formed inside the mounting frame on one side of each locking block. A placement groove is formed on the outer side of the top of the second fixed frame. A rubber ring is disposed inside the placement groove. One side of the rubber ring extends to the outside of the second fixed frame and is fixed with a sealing ring. A stainless steel filter screen is disposed at the bottom of the second fixed frame. When the locking block moves into the locking groove, the second fixed frame and the mounting frame are fixed together. Under the action of the rubber ring, the sealing ring is fixed on the outer side of the top of the second fixed frame, which enhances the sealing between the second fixed frame and the mounting frame. The stainless steel filter screen has the characteristics of acid resistance, alkali resistance, high temperature resistance, and corrosion resistance, and can work stably in harsh working environments, filtering impurities and pollutants in wastewater.

[0016] Preferably, the locking block and the mounting frame form an engaging structure via a locking groove. Handles are fixed to both sides of the top of the second fixing frame. The rubber ring and the second fixing frame form an engaging structure via a placement groove. The bottom end of the sealing ring abuts against the top end of the second fixing frame, and the bottom end of the stainless steel filter screen contacts the top end of the cleaning brush. By pulling the second fixing frame with the handles, the locking block moves to the outside of the locking groove. At this point, the second fixing frame and the mounting frame separate, allowing the second fixing frame to be moved to the outside of the filter box for replacement of the sealing ring and the stainless steel filter screen.

[0017] The filter assembly for treating chemical production wastewater provided by this utility model has the following advantages:

[0018] With a cleaning structure, when the reciprocating screw rotates, it drives the moving seat to move. The moving seat moves outside the slide bar. Under the action of the slide bar, the moving seat is prevented from rotating with the reciprocating screw. The moving seat drives the cleaning brush to clean the bottom of the stainless steel filter screen. Under the action of the reciprocating screw, the cleaning brush cleans from one side of the bottom of the stainless steel filter screen to the other side, thereby preventing the stainless steel filter screen from clogging and effectively improving the filtration effect. This device has the function of easy anti-clogging, thereby improving the working efficiency of the filter component for chemical production wastewater treatment.

[0019] With a purification structure, the first fixed frame is moved into the filter box by the cooperation of the chute and the slide plate. The top of the handle abuts against the bottom of the cover plate to limit the first fixed frame and prevent it from shaking inside the filter box. Pulling the handle moves the first fixed frame, which in turn moves the activated carbon filter and nylon filter to the outside of the filter box for cleaning. Under the action of the nylon filter and activated carbon filter, suspended particulate matter, impurities and solid particles in chemical wastewater are effectively removed. At the same time, it can adsorb and remove harmful substances, thereby improving the cleanliness of the wastewater. This realizes the function of easy purification of the device and improves the applicability of the filter component for chemical production wastewater treatment.

[0020] With its filtration structure, when the locking block moves into the slot, the second fixed frame and the mounting frame are fixed together. The rubber ring secures the sealing ring to the outer top of the second fixed frame, enhancing the seal between them. The stainless steel filter screen, resistant to acid, alkali, high temperatures, and corrosion, operates stably in harsh environments, filtering impurities and pollutants from wastewater. Pulling the handle moves the locking block to the outside of the slot, separating the second fixed frame from the mounting frame. This allows for easy replacement of the sealing ring and stainless steel filter screen, thus improving the usability of the filter assembly for chemical wastewater treatment.
