[0002] A large amount of sewage is generated in industrial production. Industrial sewage refers to wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety.

[0003] When treating sewage, free sedimentation is usually used to separate impurities from the water body. However, the treatment efficiency of free sedimentation is usually low, especially for fine suspended matter and light impurities. The sedimentation rate is slow and it takes a long time to achieve effective separation. Moreover, free sedimentation usually requires relatively stable water quality without too much suspended matter or bubbles, otherwise it will affect the sedimentation effect. In addition, the solid impurities after precipitation need to be treated and disposed of, including removal, treatment or landfill, which may increase the treatment cost and complexity.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-3 , an industrial sewage classification treatment device in this embodiment is used to classify and treat industrial sewage, separate solid waste inside the sewage from the sewage, and at the same time improve the sewage treatment efficiency;

[0030] Specifically, it includes a box body 1 and at least two partition plates 2; at least two partition plates 2 are vertically installed inside the box body 1 to divide the box body 1 into three independent chambers; the three chambers are respectively a first filter tank 101, a mixing tank 102 and a second filter tank 103 from left to right, and a water inlet pipe 7 with one end connected to the first filter tank 101 is arranged on the box body 1, and a drainage pipe 8 with one end connected to the second filter tank 103 is arranged on the right side of the box body 1.

[0031] A filtering structure 3 for filtering sewage is disposed inside the first filtering tank 101 , a stirring assembly 4 for mixing water and flocculant is disposed inside the mixing tank 102 , and a filter structure 5 for filtering the flocculant mixed liquid is disposed inside the second filtering tank 103 .

[0032] The first filter tank 101, the mixing tank 102 and the second filter tank 103 are connected by at least two drainage devices 6, one of which is used to extract the water in the first filter tank 101 and transport it to the inside of the mixing tank 102, and the other is used to extract the water in the mixing tank 102 and transport it to the inside of the second filter tank 103.

[0033] In the actual practical process, sewage is input from the inside of the water inlet pipe 7 and transported to the inside of the first filter tank 101. The sewage is preliminarily filtered by the filter structure 3 inside the first filter tank 101 to achieve solid-liquid separation of the sewage. The sewage after preliminary filtration is transported to the inside of the mixing tank 102 through the drainage device 6 on the left. By adding flocculant into the mixing tank 102 and operating the stirring component 4, the mixing efficiency of the flocculant and sewage is accelerated. After the sewage and the flocculant are effectively mixed, the water body is transported to the second filter tank 103 through the drainage device 6 on the right, and the water body is finally filtered through the filter structure 5 inside the second filter tank 103.

[0034] It should be noted that the drainage device 6 consists of two water pipes and a water pump assembly, and the two water pipes are respectively connected to the output end and the input end of the water pump. The water pipe connected to the input end is used to extract water, and the water pipe at the output end is used to discharge water.

[0035] See also Figure 3 In order to achieve the effect of solid-liquid separation for sewage, the filtering structure 3 in this embodiment includes a connecting plate 301 on the left side of the left partition plate 2; a first filter screen 302 is installed on the side of the connecting plate 301 away from the partition plate 2, and a sludge collection box 303 is provided on the side of the first filter screen 302 away from the connecting plate 301, and the front side of the sludge collection box 303 is connected to a sewage pipe 304 with one end passing through and extending to the front side of the box body 1.

[0036] In the actual practical process, the internal sewage input into the first filter tank 101 through the water inlet pipe 7 first contacts with the first filter net 302, and the impurities and floating objects are intercepted by the first filter net 302. The water body is discharged to the bottom of the first filter tank 101 through the first filter net 302. At this time, the impurities and floating objects are accumulated on the first filter net 302.

[0037] Furthermore, in order to facilitate the cleaning of impurities and floating objects on the first filter screen 302, the cross-section of the front side of the first filter screen 302 in this embodiment is arc-shaped. Corresponding to the first filter screen 302, a dredging assembly is arranged inside the first filter tank 101, and the dredging assembly includes a rotating shaft 305 rotatably connected between the front and rear sides of the inner wall of the box body 1, and at least two transmission plates 306 are distributed in a ring-shaped array on the outer side of the rotating shaft 305, and a scraper plate 307 is arranged on the side of the transmission plate 306 away from the rotating shaft 305, and one of the scraper plates 307 is attached to the inner side of the first filter screen 302 on the side away from the transmission plate 306. In addition, the center point of the first filter screen 302 and the axis of the rotating shaft 305 are located in the same Y-axis direction; a driving motor 308 with an output end transmission-connected to the rotating shaft 305 is arranged on the rear side of the box body 1, so as to drive the scraper plate 307 to rotate on the ZX plane.

[0038] In actual use, the driving motor 308 drives the rotating shaft 305 to rotate, and the transmission plate 306 and the scraper plate 307 on the outside of the rotating shaft 305 rotate accordingly. During the rotation process, the scraper plate 307 scrapes the impurities and floating objects accumulated on the inner side of the first filter screen 302, and transports them to the inside of the sludge collection box 303, and discharges them through the sewage pipe 304 connected thereto.

[0039] It should be noted that the length of the scraper plate 307 in the Y-axis direction in this embodiment is equal to the length of the first filter screen 302 in the Y-axis direction.

[0040] In detail, in order to increase the efficiency of mixing the flocculant and the water in the mixing tank 102, the stirring assembly 4 in this embodiment includes a transverse plate 401, a stirring shaft 402 and a rotating motor 403; the transverse plate 401 is installed between the front and rear sides of the inner wall of the box body 1, and is located inside the mixing tank 102, the stirring shaft 402 is rotatably connected to the center of the transverse plate 401, and the output end of the rotating motor 403 is transmission-connected to the stirring shaft 402 for the pneumatic stirring shaft 402 to rotate on the XY plane to mix the flocculant and the water inside the mixing tank 102.

[0041] In the actual practical process, the output end of the rotating motor 403 rotates to drive the stirring shaft 402 to rotate on the XY plane, so as to stir the water in the mixing tank 102, thereby accelerating the mixing efficiency of the water and the flocculant, so that the fine impurities in the water can be effectively flocculated, so as to facilitate the subsequent further filtration treatment of the water.

[0043] In actual practical use, the water inside the mixing tank 102 is extracted through the drainage device 6 on the right, and transported to the second filter screen 503 through the output end of the drainage device 6. The flocculated water is filtered through the second filter screen 503. At this time, the flocculants accumulate on the second filter screen 503, and the filtered water passes through the second filter screen 503 into the interior of the second filter tank 103.

[0044] Furthermore, in order to facilitate cleaning of the second filter screen 503, the corresponding frame 502 in this embodiment is provided with a square opening on the right side of the inner wall of the box body 1 for the frame 502 to slide left and right.

[0045] In actual practical application, by pulling the frame 502 along the X-axis direction, the frame 502 can be extracted from between the two slide rails 501, so as to clean the flocculants on the second filter screen 503 for subsequent filtering treatment.
