[0005] However, the existing filtration devices do not solve the problems of inconvenient primary filtration of large particles in coal chemical wastewater and the inability to rotate and adjust the wastewater output position, which hinders the scraping and discharge of large particles and affects the flexibility of wastewater discharge.

[0006] The purpose of this utility model is to provide a coal chemical wastewater filtration device to solve the problems mentioned in the background art, such as the inconvenience of primary filtration of large particulate matter in coal chemical wastewater and the difficulty in rotating and adjusting the output position of the wastewater, which makes it difficult to scrape and discharge the filtered large particulate matter and affects the flexibility of wastewater discharge.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a coal chemical wastewater filtration device, comprising a support frame and a lifting motor. The support frame consists of two sets, each with a lifting motor mounted at its top. Each lifting motor has a threaded rod mounted at its output end, and the threaded rod is movably connected to the support frame. A threaded sleeve is fitted onto the surface of each threaded rod, and the threaded sleeve is threadedly connected to the threaded rod. A filter box is disposed outside the support frame, and the filter box is connected to the two sets of threaded sleeves. A water outlet pipe is mounted at the bottom of the filter box, and a connecting pipe is movably mounted at the bottom of the water outlet pipe. A lower water inlet pipe is mounted at the bottom of the connecting pipe, and a toothed ring is fitted onto the surface of the connecting pipe. A rotary motor is mounted at the bottom of the filter box on one side of the water outlet pipe, and a gear is mounted at the output end of the rotary motor, with the gear meshing with the toothed ring.

[0011] Preferably, the surface of the linkage shaft is fitted with a roller brush, and the pulley assembly is connected to the linkage shaft.

[0012] Preferably, a dirt collection trough is installed on the side wall of the filter box on one side of the roller brush, and the roller brush is slidably connected to the scraping teeth.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the filtration device not only realizes convenient primary filtration of large particulate impurities in coal chemical wastewater and rotation adjustment of the wastewater output position, making it convenient to scrape and discharge the filtered large particulate impurities, but also improves the flexibility of wastewater discharge.

[0016] (1) Coal chemical wastewater is introduced into the filter box through a flexible pipe and an upper inlet pipe. An arc-shaped filter screen filters out large particles of debris from the wastewater, leaving them on its surface for primary filtration. When a significant amount of large particles accumulate on the arc-shaped filter screen, a scraping motor drives the drive shaft to rotate. This drive shaft, in turn, rotates the scraping frame and scraping teeth. The scraping teeth then scrape the large particles from the arc-shaped filter screen along its interior to the roller brush. The drive shaft then moves the pulley assembly, which, through a linkage shaft, rotates the roller brush. The roller brush then sweeps the large particles scraped up by the scraping teeth into the collection tank. The bottom of the collection tank has its own filter screen, which is connected to the inside of the filter box via a pipe. The connection allows for secondary filtration of wastewater carrying large particles to the inside of the filter box. After primary filtration, the wastewater is discharged into the sleeve through the outlet pipe, transfer pipe, and lower inlet pipe. The discharge motor drives the threaded blades to rotate via the movable shaft, which in turn drives the wastewater through the outlet to the secondary filtration device. When the wastewater output position needs to be adjusted, the rotary motor drives the gear to rotate, which in turn drives the gear ring to rotate. The gear ring then drives the transfer pipe to rotate, which in turn drives the sleeve and outlet through the lower inlet pipe. This allows for rotational adjustment of the outlet position, facilitating wastewater output from different locations. This system enables convenient primary filtration of large particles in coal chemical wastewater and allows for rotational adjustment of the wastewater output position, facilitating the scraping and discharge of the filtered large particles.

[0017] (2) By lifting the motor to drive the threaded rod to rotate, the threaded rod drives the filter box, sleeve and outlet to move upward through the threaded sleeve, thereby adjusting the drainage height of the outlet and adapting to different drainage heights, thus improving the flexibility of wastewater discharge.

[0025] Please see Figure 1-5 This utility model provides an embodiment of a coal chemical wastewater filtration device, comprising a support frame 1 and two sets of lifting motors 17. Each support frame 1 has a lifting motor 17 mounted on its top end, serving as the power drive. Each lifting motor 17 has a threaded rod 16 mounted on its output end, which is movably connected to the support frame 1. A threaded sleeve 18 is fitted onto the surface of each threaded rod 16, and the threaded sleeve 18 is threadedly connected to the threaded rod 16. A filter box 3 is disposed outside the support frame 1, and the filter box 3 is connected to the two sets of... The filter box 3 is connected by a threaded sleeve 18. A water outlet pipe 10 is installed at the bottom of the filter box 3. An adapter pipe 12 is movably installed at the bottom of the water outlet pipe 10.

A water outlet 14 is installed at the bottom of the sleeve 6. An upper water inlet pipe 2 is installed at the top of the filter box 3.

[0026] Coal chemical wastewater is introduced into the filter box 3 through a flexible pipe and the upper inlet pipe 2. A curved filter screen 19 filters out large particles of debris from the wastewater, leaving them on its surface for primary filtration. When a significant amount of large particles accumulate on the surface of the curved filter screen 19, the scraper motor 4 is activated. This motor drives the drive shaft 22, which in turn rotates the scraper frame 15 and the scraper teeth 20. The scraper teeth 20 interact with the curved filter screen... With the sliding engagement of the curved filter screen 19, the scraping teeth 20 scrape large particles of debris from the surface of the curved filter screen 19 along the inside of the curved filter screen 19 to the position of the roller brush 5. The drive shaft 22 drives the pulley assembly 23 to move, and the pulley assembly 23 drives the roller brush 5 to rotate through the linkage shaft 25. The roller brush 5 sweeps the large particles of debris scraped up by the scraping teeth 20 into the interior of the dirt collection tank 26. The bottom of the dirt collection tank 26 has a built-in filter screen and is connected to the interior of the filter box 3 through a pipe, thus removing large particles of debris from the surface. The wastewater from the mask is transported to the interior of the filter box 3 after secondary filtration. After primary filtration, the wastewater is discharged into the interior of the sleeve 6 through the outlet pipe 10, the transfer pipe 12, and the lower inlet pipe 13. The discharge motor 7 is turned on, and the discharge motor 7 drives the threaded blade 21 to rotate through the movable shaft 24. The threaded blade 21 drives the wastewater to be discharged through the outlet 14 to the secondary filtration device. When it is necessary to adjust the wastewater output position, the rotary motor 8 is turned on, and the rotary motor 8 drives the gear 9 to rotate. Under the mutual meshing of the gear 9 and the gear ring 11, the gear 9 drives the gear ring 11 to rotate. With the movable connection between the transfer pipe 12 and the outlet pipe 10, the gear ring 11 drives the transfer pipe 12 to rotate. The transfer pipe 12 drives the sleeve 6 and the outlet 14 to rotate through the lower inlet pipe 13, thereby rotating and adjusting the output position of the outlet 14 to facilitate the output of wastewater from different positions. This realizes convenient primary filtration of large particles in coal chemical wastewater and rotation adjustment of the wastewater output position, which facilitates the scraping and discharge of large particles filtered out.

[0027] The filter box 3 is equipped with an arc-shaped filter screen 19 inside. The outer wall of the filter box 3 is equipped with a scraping motor 4, which serves as a power drive. The output end of the scraping motor 4 is equipped with a drive shaft 22. The surface of the drive shaft 22 is equipped with a scraping frame 15.

A linkage shaft 25 is movably installed inside the filter box 3 on one side of the scraper frame 15. A roller brush 5 is fitted on the surface of the linkage shaft 25, and the pulley assembly 23 is connected to the linkage shaft 25.

[0029] A dirt collection trough 26 is installed on the side wall of the filter box 3 on one side of the roller brush 5, and the roller brush 5 is slidably connected to the scraping teeth 20. A discharge motor 7 is installed on the side wall of the sleeve 6. The discharge motor 7 plays the role of power drive, and the discharge motor 7 is fixedly connected to the sleeve 6.

[0030] The output end of the discharge motor 7 is equipped with a movable shaft 24, and the surface of the movable shaft 24 is fitted with a threaded blade 21, which is slidably connected to the sleeve 6.

[0031] When filtered wastewater needs to be discharged from different heights, the lifting motor 17 is turned on, which drives the threaded rod 16 to rotate. With the threaded connection between the threaded rod 16 and the threaded sleeve 18, the threaded rod 16 drives the filter box 3, the sleeve 6 and the outlet 14 to move upward through the threaded sleeve 18, thereby adjusting the drainage height of the outlet 14 to adapt to different drainage heights and improve the flexibility of wastewater discharge.

[0032] Working Principle: Coal chemical wastewater is introduced into the filter box 3 through a flexible pipe and the upper inlet pipe 2. A curved filter screen 19 filters large particles of debris from the wastewater, leaving them on its surface for primary filtration. A scraper motor 4 drives a drive shaft 22, which in turn drives a scraper frame 15 and scraper teeth 20. The scraper teeth 20 scrape the large particles from the curved filter screen 19 along its interior to the roller brush 5. The drive shaft 22 then moves a pulley assembly 23, which, via a linkage shaft 25, drives the roller brush 5. The roller brush 5 sweeps the large particles scraped by the scraper teeth 20 into the collection tank 26. The bottom of the collection tank 26 has a built-in filter screen connected to the filter box 3 via a pipe, allowing secondary filtration of the wastewater carried on the surface of the large particles. After primary filtration, the wastewater... After filtration, the wastewater flows through the outlet pipe 10, the transfer pipe 12, and the lower inlet pipe 13 into the sleeve 6. The discharge motor 7 drives the threaded blades 21 to rotate via the movable shaft 24. The threaded blades 21 carry the wastewater through the outlet 14 to the secondary filtration device. When the wastewater output position needs to be adjusted, the rotary motor 8 drives the gear 9 to rotate, which in turn drives the gear ring 11 to rotate. The gear ring 11 then drives the transfer pipe 12 to rotate, which in turn drives the sleeve 6 and the outlet 14 to rotate via the lower inlet pipe 13. This rotation adjusts the output position of the outlet 14 to facilitate wastewater output from different positions. When the filtered wastewater needs to be output from different heights, the lifting motor 17 drives the threaded rod 16 to rotate. The threaded rod 16 then drives the filter box 3, the sleeve 6, and the outlet 14 to move upward via the threaded sleeve 18, adjusting the drainage height of the outlet 14 to adapt to different drainage heights and complete the operation of the coal chemical wastewater filtration device.
