[0029] The dust scraping assembly 6 includes a dust discharge pipe 61, which is fixedly connected to the inner wall of one side of the filter tank 2. One end of the dust discharge pipe 61 extends through to the outer surface of the filter device body 1, and the other end of the dust discharge pipe 61 is fixedly connected to a dust collection box 62. The dust collection box 62 is installed inside the filter roller 53 through the dust discharge pipe 61. The dust scraping assembly 6 is used to scrape dust from the filter roller 53 and collect it uniformly.

[0030] One end of the rotating rod 52 is rotatably connected to a filter tube 55, and a filter cotton sleeve 57 is fitted on the outer surface of the filter tube 55.

[0031] One end of the filter pipe 55 is fixedly connected to the filter water drain pipe 56, the filter water drain pipe 56 is fixedly connected to one side of the filter tank 2, and the filter water drain pipe 56 extends through to the outer surface of one side of the filter device body 1.

[0032] In this embodiment, saline-alkali wastewater can be discharged into the interior of the filter tank 2 through the discharge pipe 3. The motor 51 can be fixed by the fixing plate 4. The start of the motor 51 can drive the rotating rod 52 and the filter drum 53 to rotate. The rotation of the filter drum 53 can perform preliminary filtration of the saline-alkali wastewater in the filter tank 2, screening out larger particulate impurities. Through the setting of the filter pipe 55 and the filter cotton sleeve 57, the wastewater can be filtered a second time and then discharged through the filtered water drain pipe 56.

[0033] Example 2:

[0034] Please see Figure 1-6 This embodiment provides a technical solution based on embodiment one: two first sliding grooves 63 are opened opposite each other on the top of the dust collection box 62 near the front side, and a scraper 64 is slidably arranged between the interior of the two first sliding grooves 63. The scraper 64 is arranged at the edge of the inner wall of the filter roller 53.

[0035] A limiting plate 65 is fixedly welded to the front side of the scraper 64, and a transmission groove 66 is provided at the bottom of the limiting plate 65 near the center.

[0036] A second sliding groove 67 is horizontally opened on the front side of the dust collection box 62 near the bottom. A lead screw 68 is rotatably connected to one side of the second sliding groove 67. One end of the lead screw 68 extends through to one side of the dust collection box 62 and through to one side of the filter device body 1. A torsion block 69 is fixedly welded to one end of the lead screw 68.

[0037] The second slide groove 67 has a sliding slider 610 inside, which is threadedly connected to the lead screw 68. The inner wall of the slider 610 near the top is rotatably connected to the transmission roller 611 through a fixed short rod. The transmission roller 611 is fitted into the transmission inclined groove 66.

[0038] In this embodiment, the dust collection box 62 can be fixed by the dust discharge pipe 61, and the scraper 64 can be limited by the first sliding groove 63 to ensure stability. The scraper 64 can scrape the dust on the inner wall of the filter roller 53, and scrape the impurities adsorbed on the inner wall of the filter roller 53 into the dust collection box 62. Finally, it is discharged through the dust discharge pipe 61. The rotation of the lead screw 68 can drive the slider 610 to slide and adjust in the second sliding groove 67, so that the limiting plate 65 and the scraper 64 can be adjusted up and down by the sliding engagement of the transmission roller 611 and the transmission inclined groove 66.

[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0040] When it is necessary to perform preliminary filtration of saline-alkali wastewater during operation, the saline-alkali wastewater can first be discharged into the interior of the filter tank 2 through the discharge pipe 3. By starting the motor 51, the rotating rod 52 and the filter drum 53 can be driven to rotate. The wastewater can be preliminarily filtered by the continuous rotation of the filter drum 53. The preliminarily filtered wastewater is further filtered through the filter cotton sleeve 57, and the water from the secondary filtration flows through the filter pipe 55 into the filter water drain pipe 56, and is finally discharged through the filter water drain pipe 56.

[0041] To remove dust from the equipment, rotating the torsion block 69 drives the lead screw 68 to rotate. The lead screw 68 is threadedly connected to the slider 610, allowing the slider 610 to slide within the second slide groove 67. This simultaneously drives the transmission roller 611 to slide. The sliding engagement between the transmission roller 611 and the transmission inclined groove 66, along with the angle setting of the transmission inclined groove 66, controls the height of the limit plate 65 and the scraper 64 when the slider 610 drives the transmission roller 611 to slide. When the scraper 64 is close to the inner wall of the filter drum 53, the self-locking property of the threaded connection provides a fixed limiting effect, ensuring the stability of the scraper 64. As the filter drum 53 rotates continuously, the scraper 64 scrapes the impurities adsorbed on the inner wall of the filter drum 53 into the dust collection box 62, and finally discharges them through the dust discharge pipe 61.
