Description

Technical Field

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

[0002] Solid particle separation is a key step in wastewater treatment, aiming to remove various suspended solids, particulate matter, colloidal substances, etc. from wastewater to purify the water. Currently, the most common method is to use filter media to intercept particulate matter in the water.

[0003] Currently, most processes rely on filtration equipment for separation and filtration. However, existing filtration equipment cannot automatically replace filter screens or clean impurities, requiring manual intervention. Cleaning necessitates machine shutdown, which reduces filtration efficiency and prevents continuous and effective filtration and separation. Utility Model Content

[0007] The water inlet pipe is located above the drain tank and is used to transport the water to be treated into the drain tank.

[0008] A separation mechanism is located inside the drainage tank. The separation mechanism includes multiple filter plates that are slidably disposed inside the drainage tank. A conveyor belt is installed at the bottom of the filter plates to drive the filter plates to slide cyclically inside the drainage tank.

[0009] A cleaning nozzle is located at the end of the drain tank and is used to clean the passing filter plates.

[0010] Preferably, a cover is fixedly connected to the top of the drainage tank, and the cover is fixedly connected to the water inlet pipe via a flange.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , 2 As shown in Figure 3, this utility model provides a technical solution: a wastewater separation device for wastewater treatment, comprising: a drainage tank 1, which is a cavity with an open top and two ends, and the drainage tank 1 is inclined along its length; an inlet pipe 2 is placed above the drainage tank 1 for conveying the water to be treated into the drainage tank 1; a separation mechanism is placed inside the drainage tank 1, and the separation mechanism includes multiple filter plates 7 slidably disposed inside the drainage tank 1, and a conveyor belt 4 is installed at the bottom of the filter plates 7 to drive the filter plates 7 to slide cyclically inside the drainage tank 1; and a cleaning nozzle 6 is placed at the end of the drainage tank 1 for cleaning the passing filter plates 7.

[0023] It should be noted that in this invention, sewage is discharged into the inlet pipe 2 by a water pump or other equipment and then enters the drain tank 1. Under the action of gravity, the sewage moves downward along the drain tank 1 at an incline. During this process, the sewage needs to pass through multiple filter plates 7. The filter plates 7 filter the impurities in the sewage, and the conveyor belt 4 drives the filter plates 7 to move clockwise. The filter plates 7 move the filtered impurities upward along the drain tank 1 at an incline and push them down from the upper end of the drain tank 1, so that the impurities enter the collection tank 8. When the filter plates 7 are aligned with the cleaning nozzles 6, the cleaning nozzles 6 achieve intermittent air jetting under the action of a timer. The high-pressure air blows off the impurities adhering to the outside of the filter plates 7, thereby cleaning the outside of the filter plates 7.

[0024] Please see Figure 1 , 2 As shown, a cover 3 is fixedly connected to the top of the drainage tank 1. The cover 3 is fixedly connected to the water inlet pipe 2 through a flange. A water storage tank 10 is fixedly connected to one end of the drainage tank 1 to collect the water filtered by the drainage tank 1.

[0025] It should be noted that in this utility model, the water pipe is connected to the inlet pipe 2, and the sewage is sent into the drain tank 1 through the inlet pipe 2. After being filtered by multiple filter plates 7 in the drain tank 1, the sewage flows down into the water storage tank 10. The water storage tank 10 is equipped with a water pump to transport the collected water for subsequent processing operations.

[0026] Please see Figure 3As shown, driven roller 12 and driving roller 14 are rotatably connected to the two ends of the bottom of the drainage tank 1, respectively. The conveyor belt 4 is placed outside the driven roller 12 and driving roller 14. The driven roller 12 and driving roller 14 are connected by transmission through the conveyor belt 4. The bottom side plate 15 is fixedly connected to the bottom of the drainage tank 1. Driven roller 13 is rotatably connected to the middle of the bottom side plate 15. Driven roller 13 is frictionally connected to the conveyor belt 4. The motor 11 is fixedly connected to the outside of the bottom side plate 15. The output end of the motor 11 is fixedly connected to the driving roller 14.

[0027] It should be noted that the bottom of the drainage box 1 of this utility model is located in the middle of the conveyor belt 4. The conveyor belt 4 is sleeved on the outside of the bottom of the drainage box 1. The motor 11 drives the conveyor belt 4 to rotate clockwise through the drive roller 14. The drive roller 14, the driven roller 12 and the driven roller 2 13 form a triangular structure, so that the conveyor belt 4 rotates counterclockwise on the outside of the three. The filter plate 7 moves upward along the inner wall of the drainage box 1. While filtering, the filter plate 7 tilts and conveys the impurities upward, and the cleaned filter plate 7 is placed under the water inlet pipe 2, so that the filter plate 7 can be automatically replaced.

[0028] Please see Figure 1 , 2 As shown in Figure 3, a water collection tank 8 is fixedly connected to the lower part of one end of the drainage tank 1. A collection filter plate 9 is detachably installed in the middle of the water collection tank 8. A cleaning baffle 5 is fixedly connected between the bottom side plate 15 and the water collection tank 8. A cleaning nozzle 6 is fixedly connected to the middle of the cleaning baffle 5.

[0029] It should be noted that, in this utility model, impurities fall into the lower water collection tank 8 through the upper end of the drainage tank 1. The water in the impurities is separated by the collection filter plate 9, allowing the water to fall into the water collection tank 8 for easy discharge by a water pump. The water collection tank 8 is equipped with a baffle to support the collection filter plate 9. When cleaning the collection filter plate 9, simply lift the collection filter plate 9 upwards. When the filter plate 7 moves to the position of the corresponding cleaning nozzle 6, a high-pressure air blows high-pressure air onto the outside of the filter plate 7, blowing off the impurities on the outside of the filter plate 7. Under the blocking effect of the cleaning baffle 5, the impurities are prevented from flying out, thus allowing the impurities to fall onto the collection filter plate 9 along the cleaning baffle 5.
