Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically a papermaking wastewater filtration device. Background Technology

[0002] Papermaking wastewater filtration equipment is a specialized device for treating wastewater generated during the papermaking process. It utilizes the principle of microporous filtration to filter impurities in the wastewater, such as pulp fibers or fine impurities, achieving solid-liquid separation. This device can maximize the separation of tiny suspended matter in the wastewater, improve water recycling rates, reduce water resource consumption and wastewater pollution, and is an important component of clean production in the papermaking industry. Through filtration, wastewater can be recycled, reducing environmental impact and saving production costs.

[0003] In the process of filtering papermaking wastewater, although the method of cleaning the surface of the filter plate with a scraper can effectively remove most of the waste residue, there are still some technical problems. The main problem is that waste residue remains inside the micropores of the filter plate. These residues also affect the filtration efficiency. Specifically, the paper scraps in the papermaking wastewater are of different sizes and are easy to stick to the filter mechanism and are difficult to clean. At the same time, the paper scraps can easily clog the filter holes, reducing the filtration efficiency of the filter mechanism for wastewater. Therefore, a papermaking wastewater filtration device is proposed to address the above problems. Utility Model Content

[0026] Please see Figure 1-6 This utility model provides a technical solution:

[0027] A papermaking wastewater filtration device includes a filtration assembly 1, a cleaning assembly 2 installed inside the filtration assembly 1, and a filter plate assembly 3 fixedly connected to the inside of the filtration assembly 1. The cleaning assembly 2 includes an air pump 21, a fixed housing 22 fixedly connected to the bottom end of the air pump 21, a rubber sleeve 23 fixedly connected to the bottom end of the fixed housing 22, a flat plate 24 fixedly connected to the bottom end of the rubber sleeve 23, an internal frame 25 slidably connected to the inside of the fixed housing 22, and a linear spring 26 fixedly connected to the top end of the internal frame 25. 2.

[0028] As a further implementation of this solution, the filter device assembly 1 includes a housing 11, a partition 12 fixedly connected to the inner side of the housing 11, a servo motor 13 fixedly connected to the right side of the housing 11, a threaded rod 14 fixedly connected to the end of the main shaft of the servo motor 13, a guide slide rod 15 fixedly connected to the inner side of the housing 11, the outer side of the threaded rod 14 being spirally connected to the inner side of the front end hole block 27, and the outer side of the guide slide rod 15 being slidably connected to the rear end hole block 27. The servo motor 13 drives the threaded rod 14 to rotate, thereby controlling the cleaning assembly 2 to move left and right, achieving the effect of scraping off the waste residue on the filter plate body 31, and at the same time increasing the cleaning range of the filter plate body 31.

[0029] As a further implementation of this solution, a hydraulic rod 16 is fixedly connected to the inner side of the upper end of the filter device assembly 1, a squeezing plate 17 is fixedly connected to the bottom end of the hydraulic rod 16, a stabilizing slide rod 18 is fixedly connected to the top end of the squeezing plate 17, a wastewater collection tank 19 is opened on the inner side of the lower end of the housing 11, the squeezing plate 17 is located between the threaded rod 14 and the guide slide rod 15, a sliding hole is opened on the inner side of the hydraulic rod 16 near the stabilizing slide rod 18, and the stabilizing slide rod 18 is slidably connected to the inner side of the upper end of the housing 11, which can achieve the effect of rapid filtration of papermaking wastewater;

[0030] As a further implementation of this solution, a through hole is provided on the inner side of the partition 12, and the through hole of the partition 12 is connected to the inside of the wastewater collection tank 19. The top of the partition 12 is fixedly connected to the bottom of the spring telescopic rod 32. A gap is provided between the left and right sides of the filter plate body 31 and the inner side of the housing 11 to facilitate the collection of the filtered wastewater.

[0031] As a further implementation of this solution, a sliding groove is provided on the inner side of the housing 22 near the built-in frame 25. The top of the linear spring 26 is fixedly connected to the top of the sliding groove of the housing 22. Two built-in frames 25 and two linear springs 26 are provided respectively, which can ensure that the plate 24 and the filter plate body 31 are in close contact, and improve the effect of air blowing cleaning of the micropores 35.

[0032] As a further implementation of this solution, the solid housing 22 has a through hole on its inner side near the air pump 21. The air outlet of the air pump 21 is connected to the inside of the rubber sleeve 23 through the through hole of the solid housing 22. The inner side of the rubber sleeve 23 is hollow. The hole block 27 penetrates vertically through the inner side of the plate 24. The rubber sleeve 23 is connected to the hole block 27. The micropores 35 penetrate vertically through the inner side of the filter plate body 31. There is a gap between the toothed plate 34 and the filter plate body 31. The upper end of the toothed plate 34 is provided with teeth. The number of toothed plates 34 is the same as the number of toggle rods 28. By blowing air under high pressure, the waste residue inside the micropores 35 can be quickly cleaned. By vibrating the filter plate body 31, the efficiency of cleaning the waste residue can be improved.

[0033] Workflow: When filtering papermaking wastewater, the wastewater is placed on the upper part of the filter plate body 31. The hydraulic rod 16 is activated to move the extrusion plate 17 downward. The extrusion plate 17 moves the stabilizing slide bar 18. The stabilizing slide bar 18 can improve the stability of the extrusion plate 17 when it moves downward. At this time, the cleaning component 2 is located on the upper left side of the filter plate assembly 3. The wastewater on the filter plate body 31 is squeezed by the extrusion plate 17. The wastewater can quickly flow out through the micropores 35. Waste residue is left on the upper part of the filter plate body 31. At this time, the filter plate body 31 will move downward a certain distance. The filter plate body 31 squeezes the spring telescopic rod 32. The spring telescopic rod 32 acts as a buffer when the extrusion plate 17 squeezes the filter plate body 31, and at the same time, it also acts as a reset function for the filter plate body 31. At this time, the filtration of wastewater is completed.

[0034] When collecting waste residue on the filter plate body 31 and cleaning the waste residue inside the micropores 35, the servo motor 13 is started to drive the threaded rod 14 to rotate. The threaded rod 14 drives the hole block 27 and the fixed housing 22 to move to the right. The rear hole block 27 slides on the outside of the guide slide rod 15, which limits the overall movement direction of the cleaning assembly 2. When the cleaning assembly 2 moves to the right, the air pump 21 is started to blow high-pressure gas into the rubber sleeve 23 through the through hole of the fixed housing 22. The rubber sleeve 23 is made of rubber to prevent the gas from flowing out. At this time, the gas will be blown out from the hole block 27. The blowing of air through the hole block 27 achieves the effect of unblocking the waste inside the micropores 35. The bottom of the plate 24 is connected to the filter plate body 31. The top of the filter plate body 31 remains in contact, which reduces gas leakage. When the cleaning assembly 2 moves as a whole, the waste residue on the filter plate body 31 can be pushed to the upper right end of the partition plate 12. When the actuating rod 28 moves, the push of the actuating rod 28 and the elasticity of the spring telescopic rod 32 can create a vibration effect on the filter plate body 31, improving the efficiency of cleaning the waste residue inside the filter plate body 31. When the filter plate body 31 moves downward, the linear spring 26 pushes the plate 24 and the built-in frame 25 downward, ensuring that the plate 24 and the filter plate body 31 remain in contact, thereby greatly improving the unblocking effect of the filter plate body 31 and ensuring the efficiency of the filter plate body 31 in filtering papermaking wastewater again.

[0035] 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.
