[0003] In existing technologies, due to the complex composition of coal chemical wastewater, containing impurities of varying sizes and corrosive properties, the filtration structures in traditional wastewater deep treatment equipment often require periodic shutdowns for manual cleaning and maintenance, resulting in high maintenance costs. Furthermore, the filter cleaning structures in traditional wastewater treatment equipment are mostly in direct contact with the wastewater, causing the transmission components to come into direct contact with the wastewater or moisture, leading to rust or damage to these components and consequently, failure or malfunction of the cleaning structure. Therefore, this utility model proposes a coal chemical wastewater deep treatment device to solve the problems existing in the prior art. Utility Model Content

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please see Figures 1-5 This utility model provides an embodiment of a deep treatment device for coal chemical wastewater, including a filter box 1, a cleaning slider 5, a transverse support frame 18, and a servo motor 19. Second grooves 10 are formed at the inner edges of the left and right ends of the filter box 1. A first groove 7 is formed through one side of the second groove 10 near the left and right ends of the filter box 1. A motor groove 8 is formed on the inner wall of the rear end of the first groove 7 located at the right end of the filter box 1. A servo motor 19 is installed in the motor groove 8. A lead screw body 20 is installed on the output end of the servo motor 19. The front end of the lead screw body 20 is rotatably mounted on the right side of the filter box 1. The inner wall of the first groove 7 at the front end is fixed with a second guide rail 13 and a first guide rail 12 that are symmetrically distributed vertically. Several sets of cleaning sliders 5 are installed through the transverse support frame 18. Limit bolts 17 are installed on the outer walls of the upper and lower ends of the cleaning sliders 5. The left and right ends of the transverse support frame 18 are fixed with a first movable block 14 and a second movable block 21 respectively. The front and rear ends of the first movable block 14 and the second movable block 21 are respectively provided with two sets of first sliding grooves 15 and second sliding grooves 22 that are symmetrically distributed vertically. The right end of the second movable block 21 is fixed with a threaded sleeve 23.

[0017] By precisely matching the limit bolt 17 of the cleaning slider 5 with the filter tank, the cleaning can directly act on the attachment point of impurities, which is more efficient than the traditional whole scraping and does not damage the filter screen. At the same time, the servo motor 19, lead screw and guide rail are set in an independent first tank 7 and isolated from the filtration area by the waterproof baffle 6, which not only ensures the stable operation of the transmission components, but also reduces wastewater corrosion, taking into account both transmission efficiency and component protection.

[0018] Please see Figures 3-5 In this embodiment, the inner wall of the filter box 1 is equipped with coarse filter plates 3 and fine filter plates 4 symmetrically distributed vertically. A transverse support frame 18 is located between the coarse filter plates 3 and fine filter plates 4. The first movable block 14 and the second movable block 21 are respectively located in the two sets of first grooves 7. The coarse and fine filter plates 4 symmetrically distributed vertically form a double-layer filtration structure. First, larger impurities are intercepted by the coarse filter plate 3, and then fine particles are filtered by the fine filter plate 4, improving filtration accuracy and efficiency. The transverse support frame 18 is located between the two, which avoids interfering with the filtration process and can stably support the cleaning components. At the same time, it provides space for impurities to be temporarily stored between the two layers of filters, reducing the risk of clogging. The upper and lower ends of the coarse filter plate 3 and the fine filter plate 4 are respectively provided with several sets of equidistantly distributed first filter grooves 24 and second filter grooves 25. The limiting bolt 17 at the upper end of the cleaning slider 5 is adapted to the first filter groove 24, and the limiting bolt 17 at the lower end of the cleaning slider 5 is adapted to the second filter groove 25. The upper and lower ends of the cleaning slider 5 are respectively located in the first filter groove 24 and the second filter groove 25. Filter tank 25, the first filter tank 24, and the second filter tank 25 are the filtration channels for the coarse filter screen 3 and the fine filter screen 4, respectively. Their equidistant distribution ensures uniform liquid flow. The limiting bolt 17 of the cleaning slider 5 is adapted to the filter tank, allowing the cleaning slider 5 to slide precisely along the filter tank, specifically removing impurities attached to the filter screen surface, avoiding the tedious manual cleaning, and preventing slider deviation during cleaning to ensure cleaning effectiveness. A waterproof baffle 6 is installed on the inner wall of the second tank 10 near the left and right ends of the filter box 1. Two sets of symmetrically distributed limiting grooves 16 are provided at both ends of the 6. The connecting shafts at both ends of the transverse support frame 18 pass through the limiting grooves 16 and are connected to the first movable block 14 and the second movable block 21. The waterproof baffle 6 can prevent the lead screw and guide rail from seeping into the second tank 10, thus avoiding component corrosion and extending the service life of the equipment. The limiting grooves 16 are adapted to both ends of the transverse support frame 18, which not only positions the support frame to prevent it from swaying laterally, but also does not affect the longitudinal movement of the support frame, thus ensuring the stable operation of the cleaning component.

[0019] Please see Figures 2-5In this embodiment, the inner walls of the first slide groove 15 and the second slide groove 22 are in contact with the outer walls of the first guide rail 12 and the second guide rail 13. The lead screw body 20 is threadedly fitted with the threaded sleeve 23. The first and second slide grooves 22 are tightly fitted with the corresponding guide rails to ensure that the first and second movable blocks 21 slide smoothly along a fixed trajectory, reducing operating noise and wear. The lead screw body 20 is located between the first guide rail 12 and the second guide rail 13, and the first movable block 14 and the second movable block 21 are located near one end of the transverse support frame 18. The end of the waterproof baffle 6 is close to the transverse support frame 18. The screw is located between the two guide rails, so the force is more balanced and the deviation when the moving block moves is reduced. A sinking trough 11 is opened at the edge of the upper opening of the filter box 1. A feed hopper 2 is installed in the sinking trough 11. A dustproof mesh plate 9 is installed on the side of the first tank 7 near the left and right ends of the filter box 1. The feed hopper 2 installed in the sinking trough 11 can prevent the liquid from overflowing when it is poured in. At the same time, the feed direction is guided by the tank structure so that the liquid flows into the filter box 1 evenly.

[0020] When in use, the coal chemical wastewater to be treated is first poured into the feed hopper 2 at the top of the filter box 1. The structure of the sink trough 11 can prevent the wastewater from overflowing and guide the wastewater to flow evenly into the filter box 1 to ensure uniform filtration in the later stages. After entering the filter box 1, the wastewater first flows through the upper coarse filter screen 3, and the first filter tank 24 intercepts larger impurities in the wastewater, such as particulate residues and flocculent matter. Then, the pre-filtered wastewater flows through the lower fine filter screen 4, and the second filter tank 25 filters out fine particulate impurities, completing deep purification and improving the effluent accuracy. At the same time, the servo motor 19 is started, and its output end drives the lead screw body 20 to rotate. Since the threaded sleeve 23 is adapted to the lead screw, it will drive the second movable block 21 to move along the first guide rail 12 and the second guide rail 13. The second movable block 21 drives the transverse support frame 18 to move synchronously, and the cleaning slider 5 on the transverse support frame 18 moves together. The limit bolts 17 at the upper and lower ends of the cleaning slider 5 are respectively embedded in the filter grooves of the coarse and fine filter screen plates 4. When the cleaning slider 5 slides along the first filter groove 24 and the second filter groove 25, it can directly scrape off the impurities attached to the surface of the coarse filter screen 3 and the fine filter screen 4, avoiding the impurities from clogging the filter grooves. During the cleaning process, the transverse support frame 18 is kept stable by the limiting groove 16 of the waterproof baffle 6 and does not deviate. At the same time, the waterproof baffle 6 can also reduce the probability of wastewater seeping into the first tank 7 and the second tank 10, thereby reducing the possibility of rust on the internal screw and guide rail.

[0021] Through the above steps, the limiting bolt 17 of the cleaning slider 5 is precisely matched with the filter tank, and the cleaning can directly act on the attachment point of impurities. Compared with the traditional whole scraping, it is more efficient and does not damage the filter screen. At the same time, the servo motor 19, lead screw and guide rail are set in the independent first tank 7 and isolated from the filtration area by the waterproof baffle 6. This ensures the stable operation of the transmission components and reduces wastewater corrosion, taking into account both transmission efficiency and component protection. It solves the problems of easy clogging of the filter structure and easy damage to the cleaning structure in the existing coal chemical wastewater filter box 1 during use.

[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
