When the moving block moves upward, the particulate impurities will float up again under the flow of wastewater and attach to the separation net to block it. Therefore, a wastewater treatment device for organic garbage leachate wastewater is proposed to solve the above problems. Content of the Utility Model

Specific embodiments

[0024] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be construed as a limitation on the protection scope of the present utility model.

[0025] Please refer to Figures 1-6 , the present utility model provides a technical solution: an organic waste leachate wastewater treatment device, including a treatment box 1, a discharge pipe 2 is fixedly connected to the surface of the treatment box 1, a servo motor 3 is fixedly connected to the surface of the treatment box 1, the output end of the servo motor 3 is rotatably connected to the inside of the treatment box 1, a reciprocating lead screw 4 is rotatably connected to the inside of the treatment box 1, one end of the reciprocating lead screw 4 located inside the treatment box 1 is fixedly connected to the output end of the servo motor 3, a separation net 5 is fixedly connected to the inside of the treatment box 1, a slide plate 7 is threadedly connected to the surface of the reciprocating lead screw 4, the surface of the slide plate 7 is slidably connected to the inner wall of the treatment box 1, a scraper 8 is slidably connected to the inside of the slide plate 7, the surface of the scraper 8 is slidably connected to the surface of the separation net 5, a limiting rod 10 is fixedly connected to the inside of the treatment box 1, the surface of the limiting rod 10 is slidably connected to the inside of the slide plate 7, a collection box 18 is fixedly connected to the inside of the treatment box 1, a groove 15 is provided on the surface of the collection box 18, and a separation net 5 is also provided on the surface of the collection box 18.

[0026] When the servo motor 3 starts, the output end of the servo motor 3 drives the reciprocating lead screw 4 to rotate. Since the sliding plate 7 is slidably connected to the limiting rod 10, under the limitation of the limiting rod 10, the sliding plate 7 will slide up and down on the surface of the limiting rod 10 as the reciprocating lead screw 4 rotates. Furthermore, the sliding plate 7 drives the scraping plate 8 to move, and the scraping plate 8 moves to scrape the impurities attached to the surface of the separation net 5. As the sliding plate 7 and the scraping plate 8 move, the scraped impurities will gradually approach the bottom of the treatment tank 1 along with the movement of the sliding plate 7 and the scraping plate 8, so that the impurities enter the interior of the collection box 18 through the groove 15, collecting the scraped impurities. The squeezed wastewater will flow backward through the separation net 5 on the surface of the collection box 18. By starting the servo motor 3, the sliding plate 7 and the scraping plate 8 move to collect the impurities attached to the surface of the separation net 5, thus preventing the scraped impurities from being stirred and attached to the surface of the separation net 5 again as the water flows, and further ensuring the filtering effect of the device on the wastewater, which is convenient for people to use.

[0027] The surfaces of the sliding plate 7 and the scraping plate 8 are set to be inclined, and the inner bottom surface of the treatment tank 1 is also set to be inclined. When the sliding plate 7 and the scraping plate 8 move downward and squeeze the impurities scraped from the separation net 5, due to the setting of the bottom inclined surface, the impurities will slide down into the interior of the collection box 18 along with the inclined surface under the carrying of the water flow, which is convenient for collecting the scraped impurities.

[0028] A baffle 11 is slidably connected to the inner wall of the collection box 18. Both sides of the baffle 11 are fixedly connected with rotating rods 13. The surface of the rotating rod 13 is rotatably connected to the interior of the collection box 18. A torsion spring 14 is movably sleeved on the surface of the rotating rod 13. Both ends of the torsion spring 14 are fixedly connected with the rotating rod 13 and the collection box 18 respectively. A convex block 12 is fixedly connected to the surface of the baffle 11, and the surface of the convex block 12 is inclined.

[0029] When the scraping plate 8 moves to be in contact with the convex block 12, the scraping plate 8 squeezes the inclined surface of the convex block 12. Then the convex block 12 is stressed to push the baffle 11, so that the baffle 11 rotates around the rotating rod 13. At this time, the baffle 11 no longer blocks the groove 15, so that the impurities and wastewater enter the interior of the collection box 18. Since the rotation of the rotating rod 13 twists the torsion spring 14, when the scraping plate 8 no longer squeezes the convex block 12, under the elastic force of the torsion spring 14, the torsion spring 14 drives the rotating rod 13 and the baffle 11 to rotate back to cover the groove 15 again, thus preventing the impurities from running out of the interior of the collection box 18 and mixing with the external wastewater.

[0030] Inside the slide plate 7, a first spring 9 is fixedly connected. One end of the first spring 9 away from the slide plate 7 is fixedly connected to the scraping plate 8. A limiting groove 6 is formed on the inner wall of the treatment tank 1, and the limiting groove 6 is arranged in two sections, namely the left first section groove and the right second section groove. The lower end of the left first section groove is slightly deeper than the lower end of the right second section groove, and the upper end of the left first section groove is slightly shallower than the upper end of the right second section groove. The left first section groove and the right second section groove are connected end to end. A limiting rod 17 is slidably connected inside the scraping plate 8. A second spring 16 is fixedly connected inside the scraping plate 8. One end of the second spring 16 away from the scraping plate 8 is fixedly connected to the limiting rod 17. The surface of the limiting rod 17 is slidably connected to the inner wall of the limiting groove 6.

[0031] When the slide plate 7 and the scraping plate 8 move, the scraping plate 8 drives the limiting rod 17 to move. When the limiting rod 17 moves to the bottom of the limiting groove 6, at this time, the limiting rod 17 enters the inside of the left first section groove from the right second section groove. And because the lower end of the left first section groove is slightly deeper than the right second section groove, the limiting rod 17 enters the left first section groove. When the scraping plate 8 rises, the limiting rod 17 will be blocked by the right second section groove, so that the limiting rod 17 can only slide inside the left first section groove when rising, resulting in the scraping plate 8 moving towards the inside of the slide plate 7 and no longer contacting the surface of the separation net 5. When the scraping plate 8 drives the limiting rod 17 to move to the top, the limiting rod 17 will move into the right second section groove from the left first section groove. At the same time, because the upper end of the left first section groove is slightly shallower than the right second section groove, the upper end of the left first section groove will block the limiting rod 17, so that the limiting rod 17 can only slide inside the right second section groove when descending. At this time, the scraping plate 8 slides out of the slide plate 7 and contacts the separation net 5 again, thus avoiding the situation that when the slide plate 7 and the scraping plate 8 move downward, and the discharge pipe 2 has been discharging wastewater into the treatment tank 1. At this time, part of the separation net 5 above the slide plate 7 and the scraping plate 8 filters the incoming wastewater, and impurities will adhere to its surface. And when the scraping plate 8 moves upward, it will scrape the impurities filtered by the separation net 5, thus avoiding the situation that the scraped impurities are located above the slide plate 7 and the scraping plate 8 and cannot move downward, improving the use effect of the device.

[0032] Working principle: The servo motor 3 is started, and the output end of the servo motor 3 drives the reciprocating lead screw 4 to rotate. Under the restriction of the limiting rod 10, the slide plate 7 will slide up and down on the surface of the limiting rod 10 as the reciprocating lead screw 4 rotates. The slide plate 7 drives the scraping plate 8 to move to scrape the impurities attached to the surface of the separation net 5. As the slide plate 7 and the scraping plate 8 move, the scraped impurities will gradually move closer to the bottom of the treatment tank 1 with the movement of the slide plate 7 and the scraping plate 8, so that the impurities enter the inside of the collection box 18 through the groove 15 to collect the scraped impurities.

[0033] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those of ordinary skill in the art.
