Description

Technical Field

[0001] This utility model relates to the field of chemical environmental protection equipment technology, specifically an environmentally friendly chemical waste filtration device. Background Technology

[0002] In chemical production processes, large quantities of complex waste liquids with high levels of suspended solids are generated. These waste liquids must undergo effective solid-liquid separation before discharge or further treatment. Currently, most common filtration devices use fixed filter screens or cartridges. When processing viscous chemical wastes or those containing large amounts of solid particles, the filter screens are prone to clogging, leading to a sharp decline in filtration efficiency. This necessitates frequent shutdowns for manual cleaning or replacement of filter media, which is not only cumbersome and costly to maintain, but also prone to causing secondary pollution during cleaning. Furthermore, traditional filtration devices often have limited functionality, lacking proactive designs for waste pretreatment and anti-clogging, making it difficult to meet the demands of efficient, continuous, and environmentally friendly modern chemical production. Therefore, there is an urgent need for an environmentally friendly chemical waste filtration device that can automatically clear clogging, is easy to maintain, and offers high filtration efficiency.

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.

[0014] Please see Figure 1 - Figure 4 An environmentally friendly chemical waste filtration device includes a device body 1, a first filter component, and a second filter component. The device body 1 has a support leg 101 at the bottom and a feed pipe 2 at the top. A filter box 3 is provided on one side of the lower end of the device body 1. A second slot 301 is provided on the top of the filter box 3. The second filter component is inserted into the second slot 301. A discharge pipe 4 is connected to the side of the filter box 3 away from the device body 1. A first slot 102 is provided on the side of the device body 1 away from the filter box 3. The first filter component is inserted into the first slot 102. The first filter assembly includes a first mounting frame 5 and a scraper 8. A first mounting groove 501 is provided on one side of the inner wall of the first mounting frame 5. A lead screw 6 is provided in the first mounting groove 501. One end of the lead screw 6 is rotatably connected to the inner wall of the first mounting groove 501, and the other end is drivenly connected to the output end of the first motor 601. A transmission block 7 is threaded onto the lead screw 6. The side of the transmission block 7 away from the first mounting groove 501 is fixedly connected to one end of the scraper 8. A second mounting groove 502 is provided on the inner wall of the side of the first mounting frame 5 away from the first mounting groove 501. A guide rod 9 is provided in the second mounting groove 502. The guide rod 9 passes through the other end of the scraper 8 and is movably connected to the scraper 8. Support plates 503 are provided on both sides of the lower end of the first mounting frame 5. A coarse filter screen 10 is provided between the two support plates 503. A first rubber sealing strip 504 is provided around the top and bottom of the first mounting frame 5. A first handle 505 is provided on the outer periphery of the first mounting frame 5 away from the guide rod 9.

[0015] Through the above technical solution, a feed pipe 2 is set up for feeding waste material. The waste material first falls onto the coarse filter screen 10 of the first filter assembly for preliminary filtration. The first motor 601 drives the lead screw 6 to rotate, causing the transmission block 7 to move along the guide rod 9, thereby pushing the scraper 8 to scrape the filter residue trapped on the coarse filter screen 10 onto the support plate 503, realizing automatic slag removal and effectively preventing blockage. The liquid after preliminary filtration enters the lower part of the device, and after further fine filtration by the second filter assembly, it is discharged through the discharge pipe 4. The entire first filter assembly can be pulled out from the first slot 102 as a whole through the first handle 505. The first rubber sealing strip 504 on it ensures the sealing during installation and greatly facilitates maintenance and cleaning.

[0016] This utility model provides a technical solution in which a connecting plate 11 is provided below the first filter component inside the device body 1, and a rotating column 12 is provided below the connecting plate 11. The top of the rotating column 12 is rotatably connected to the bottom of the connecting plate 11, and the bottom of the rotating column 12 is drivenly connected to the output end of the second motor 1201 provided at the bottom of the device body 1. Multiple sets of stirring blades 1202 are provided on the outer periphery of the rotating column 12.

[0017] Through the above technical solution, the connecting plate 11 set below the first filter component inside the device body 1 provides top support for the rotating column 12. The top of the rotating column 12 is rotatably connected to the bottom of the connecting plate 11, and the bottom is driven to the output end of the second motor 1201 at the bottom of the device body 1, forming a stable rotation drive structure. When the second motor 1201 is started, it can drive the rotating column 12 and the multiple sets of stirring fan blades 1202 set on the outer periphery to rotate synchronously, and fully stir the waste material after coarse filtration by the first filter component. This effectively breaks down and disperses any clumps of solid material that may remain in the waste material, preventing large particles or agglomerated impurities from directly entering the subsequent filtration stage and causing blockage. This improves the smoothness and filtration effect of the overall filtration process. At the same time, the stirring process can also make the waste material composition more uniform, which is convenient for the subsequent second filter component to perform precise fine filtration.

[0018] This utility model provides a technical solution in which the second filter assembly includes a second mounting frame 13 and a vibrator 16. A baffle 14 is provided at the bottom of the side of the second mounting frame 13 near the device body 1, and a fine filter screen 15 is provided on the other side of the second mounting frame 13. A vibrator 16 is provided at the top of the second mounting frame 13. A second rubber sealing strip 1301 is provided at the upper end of both side walls of the second mounting frame 13, and a second handle 1302 is provided at the top of the second mounting frame 13.

[0019] Through the above technical solution, the interior of the second mounting frame 13 is enclosed by a baffle 14 and a fine filter screen 15 to form an independent waste collection chamber. When the fine filter material passes through the fine filter screen 15, the vibrator 16 set on its top can generate high-frequency vibration, which effectively prevents solid particles from clogging the filter screen pores and ensures filtration efficiency. The intercepted solid waste falls into the collection chamber for temporary storage under the action of vibration. The second mounting frame 13 is tightly fitted to the second slot 301 through the second rubber sealing strips 1301 on both sides to ensure the sealing of the filtration process. When cleaning is required, the entire second filter assembly can be quickly pulled out of the device through the second handle 1302, which is simple to maintain and avoids secondary pollution.

[0020] The working principle of this utility model is as follows: After chemical waste is fed into the main body 1 through the feed pipe 2, it is first coarsely filtered by the coarse filter screen 10 of the first filter assembly. The first motor 601 periodically drives the lead screw 6 to move the transmission block 7 and scraper 8 along the guide rod 9, scraping the filter residue trapped on the coarse filter screen 10 onto the support plate 503. The liquid-solid mixture after coarse filtration falls down and is stirred and broken by the stirring fan blades 1202 on the rotating column 12 driven by the second motor 1201 before entering the second filter assembly. Under pressure, the liquid is finely filtered through the fine filter screen 15 and discharged through the discharge pipe 4. At the same time, the high-frequency vibration of the vibrator 16 effectively prevents the fine filter screen 15 from clogging. The trapped fine particles fall into the collection chamber formed by the baffle 14 and the fine filter screen 15. When maintenance is required, the entire first and second filter assemblies can be pulled out from the first slot 102 and the second slot 301 for cleaning through the first handle 505 and the second handle 1302, respectively.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
