Description

Technical Field

[0001] The utility model belongs to the field of sewage treatment, and in particular relates to a sediment impurity removing device for sewage treatment. Background Art

[0002] Wastewater treatment is the process of removing pollutants from wastewater through physical, chemical, biological and other methods to make it meet the discharge standards or reuse requirements. Wastewater treatment is widely used in the treatment of urban sewage, industrial wastewater and rural sewage, with the purpose of protecting the environment and public health. Among them, sedimentation tank treatment is a major step. Sedimentation treatment usually uses gravity and chemical agent reaction to let the sewage stay in the sedimentation tank for a period of time, so that the suspended matter and sediment naturally settle to the bottom. During the sedimentation process, heavier solid particles will gradually settle to the bottom of the pool to form a sludge layer, while the clearer sewage on the upper layer can enter the next sewage treatment process.

[0003] After sewage is deposited, it is usually necessary to use a scraper to clean the settled sludge layer. The scraper blade is driven by a motor to rotate, and then the sludge on the bottom of the pool is scraped into the sewage outlet. However, existing scrapers usually use scrapers with fixed angles. For sewage with different components, the thickness of the precipitated sludge varies. When the sludge is too thick, the scraper resistance may be too large, resulting in the motor being unable to drive. Utility Model Content

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0021] like Figures 1 to 3 As shown, a sediment impurity removal device for sewage treatment provided by an embodiment of the utility model includes a sedimentation tank 1, a sewage outlet 2 integrally formed with the sedimentation tank 1 and arranged at the bottom of the sedimentation tank 1, and also includes:

[0022] A scraping unit 7, wherein the scraping unit 7 is arranged inside the sedimentation tank 1, and the scraping unit 7 includes side scrapers 8 on both sides for scraping mud, one side of two groups of the side scrapers 8 are both close to the inner wall of the sedimentation tank 1, and the other sides of the two groups of the side scrapers 8 are both fixedly connected with a fixing rod 9, one end of the two groups of the fixing rod 9 is fixedly connected with a ring joint 10, and multiple groups of first lock buckles 11 are fixedly arranged on the outside of the fixing rod 9 by bolts, and a first movable shaft 12 is movably arranged below the first lock buckle 11, and a main scraper 13 is fixedly connected to the lower end of the first movable shaft 12, and second movable shafts 14 are fixedly arranged on both sides of the upper end of the main scraper 13, and the upper ends of the second movable shafts 14 are movably arranged in the second lock buckle 15, and the second lock buckle 15 is fixedly arranged on the outside of the movable rod 16 by bolts;

[0023] The adjusting unit 17 is disposed in the middle of the two groups of movable rods 16 . The adjusting unit 17 includes a rack 18 fixedly disposed inside the two groups of movable rods 16 . Both groups of the racks 18 are meshed with a gear 19 .

[0024] In one embodiment of the utility model, by setting a first movable shaft 12 movably set in the first lock buckle 11, cooperating with the second movable shaft 14 movably set in the second lock buckle 15, and then through the rack 18 set in the adjustment unit 17, meshing with the gear 19, the rack 18 can be driven by rotating the gear 19 to drive the movable rod 16 to move, and then the main scraper 13 can be adjusted to a suitable angle based on the thickness of the sludge layer, thereby changing the squeezing force of the sludge on the main scraper 13, so that the motor load is within a controllable range, thereby improving the applicability of the device.

[0025] In one example of the utility model, the side scraper 8 is provided as a supplement to the main scraper 13 to prevent the main scraper 13 from having a blind area on the outermost side after rotation, which causes the sludge to be unable to be completely processed, and the sludge at the bottom of the side wall of the sedimentation tank 1 can be further scraped off.

[0026] like Figure 1 to Figure 2 and Figure 4 As shown, as a preferred embodiment of the utility model, a working platform 3 is fixedly provided on the top of the sedimentation tank 1, a transmission mechanism is provided in the middle of the working platform 3, the transmission mechanism includes a motor 4, a fixing seat 5 for fixing is provided below the motor 4, the main shaft of the motor 4 is fixedly connected to the main transmission shaft 6, a sleeve 61 is sleeved on the outer side of the main transmission shaft 6, and a sleeve 62 is movably sleeved on the outer side of the main transmission shaft 6 corresponding to the sleeve 61 above.

[0027] In an example of the present invention, a motor 4 is provided as a power source of the device, and a main transmission shaft 6 is provided to drive the device to rotate.

[0028] like Figure 4 As shown in the figure, as a preferred embodiment of the utility model, the sleeve 61 is set as a round tube with an inner diameter the same as the outer diameter of the main transmission shaft 6, and a nut 611 for manual adjustment is set at the upper end of the sleeve 61. The sleeve 62 is set as a trumpet-shaped structure with a narrow upper part and a wide lower part, and the lower end of the sleeve 62 is matched with the nut 611, and the upper end of the sleeve 62 is provided with a hexagonal hole for transmission, and the outer side of the main transmission shaft 6 is provided with a section of a hexagonal cross-section corresponding to the sleeve 62.

[0029] In one example of the present invention, a sleeve 62 is provided which can move outside the main transmission shaft 6. With the structure of the upper and lower ends of the sleeve 62, when the lower end of the sleeve 62 is sleeved on the nut 611, the sleeve 61 can be rotated synchronously with the main transmission shaft 6. By lifting the sleeve 62, a wrench can be used to rotate the nut 611 and then the sleeve 61.

[0030] like Figure 3As shown, as a preferred embodiment of the utility model, the ring joint 10 is fixedly arranged on the outer side of the lower end of the main transmission shaft 6, and the gear 19 is fixedly arranged on the outer side of the lower end of the sleeve 61.

[0031] In an example of the utility model, the main transmission shaft 6 drives the ring joint 10 to drive the scraper unit 7 to rotate as a whole, and the rotating sleeve 61 drives the gear 19 to rotate, thereby driving the rack 18 to drive the movable rod 16 to move.

[0032] In one example of the utility model, during use, the sewage to be treated is first discharged into the sedimentation tank 1, and appropriate chemical reagents are added. After several days of sedimentation, the upper clear liquid is discharged, the sleeve 62 is lifted, and the sleeve 61 is rotated with a wrench to rotate the gear 19. The rotation of the gear 19 drives the rack 18 to move, and then drives the movable rod 16 to move, so that the main scraper 13 rotates around the first movable shaft 12. After adjusting to a suitable angle, the sleeve 62 is lowered and fitted with the nut 611, and the motor 4 is started to drive the main transmission shaft 6 to rotate. Under the rotation and scraping of the main scraper 13 set at a certain angle to the bottom of the pool, the sludge on the bottom of the pool is finally scraped into the sewage outlet 2.
