[0002] Wastewater treatment refers to the removal of pollutants from water through physical, chemical, and biological methods to meet discharge or reuse standards. The main purpose of wastewater treatment is to protect the environment, prevent water pollution, and safeguard human health and ecological balance.

[0003] Sludge collection devices for wastewater treatment ponds are used to remove solid impurities floating on the surface of wastewater ponds. They play an important role in the wastewater treatment process, preventing sludge from accumulating on the pond surface and interfering with subsequent treatment processes. They also help maintain the normal operation and clean appearance of the wastewater treatment pond.

[0004] In the prior art, such as the scum collection device for a sewage treatment pond disclosed in Chinese Publication No. CN210751500U, a first threaded rotating rod is provided at the rear of the sewage treatment pond. A first collar is threaded onto the right side of the first threaded rotating rod. A first support rod is welded to the upper end of the first collar, and a second support rod is welded to the lower end of the first collar. A second threaded rotating rod is provided at the front of the sewage treatment pond. A second collar is threaded onto the right side of the second threaded rotating rod. A third support rod is welded to the upper end of the second collar. A first connecting rod is welded between the third support rod and the first support rod. A scum collection device is provided on the first connecting rod. A fourth support rod is welded to the lower end of the second collar. A second connecting rod is welded between the fourth support rod and the second support rod.

[0005] The aforementioned application uses the operation of the first motor, the lead screw, and the second motor to drive the scum collection device to collect scum in the sewage treatment tank, which can improve work efficiency. However, during use, it is inconvenient to collect scum inside the filter shovel when the filter shovel is collecting scum, which is quite labor-intensive. Utility Model Content

Through the provided second sliding grooves, the slider can slide normally inside the filter shovel.

[0009] Preferably, the outer wall thread of the first lead screw penetrates the surface of the slider, and the bottom of the cleaning plate is slidably connected to the inner wall of the filter shovel. By rotating the first lead screw forward or backward, the slider can slide back and forth inside the filter shovel.

[0010] Preferably, a set of electric push rods is fixedly installed on the outer wall of the movable frame. The shaft end of the electric push rod is fixedly connected to the top of the bracket. The height of the filter shovel and the bracket can be adjusted by the electric push rods.

[0011] Preferably, a guide rod is fixedly connected to the outer wall of the treatment tank body, and the outer wall of the guide rod is slidably connected to the inside of the movable frame. The guide rod can improve the stability of the movable frame when it moves left and right.

[0012] Preferably, a control panel is fixedly installed on one side of the outer wall of the treatment pool body, so that users can easily operate and control the components through the control panel.

[0025] like Figure 1 and Figure 3 As shown, the top two sides of the filter shovel 201 are provided with second sliding grooves 203. The inner wall of the second sliding groove 203 is slidably connected to the outer wall of the slider 207. Through the second sliding groove 203, the slider 207 can slide normally in the filter shovel 201.

[0026] like Figure 1 and Figure 3 As shown, the outer wall thread of the first lead screw 206 penetrates the surface of the slider 207, and the bottom of the cleaning plate 209 is slidably connected to the inner wall of the filter shovel 201. By rotating the first lead screw 206 forward or backward, the slider 207 can slide back and forth inside the filter shovel 201.

[0027] like Figure 1 As shown, a set of electric push rods 106 are fixedly installed on the outer wall of the movable frame 105. The shaft end of the electric push rod 106 is fixedly connected to the top of the bracket 204. The height of the filter shovel 201 and the bracket 204 can be adjusted by the electric push rods 106.

[0028] like Figure 1 and Figure 2As shown, a guide rod 104 is fixedly connected to the outer wall of the treatment tank body 101. The outer wall of the guide rod 104 is slidably connected to the inside of the movable frame 105. The guide rod 104 can improve the stability of the movable frame 105 when it moves left and right.

[0029] like Figure 1 and Figure 2 As shown, a control panel 103 is fixedly installed on one side of the outer wall of the treatment tank body 101. The control panel 103 allows users to easily operate and control the components.

The interior of the solenoid valve 102 is connected to the treatment tank body 101. The solenoid valve 102 can be used to control the opening and closing of the sewage discharge pipe.

[0031] The usage and working principle of this device are as follows: First, connect it to an external power supply to ensure normal operation. When collection is required, control the servo motor 108 via the control panel 103 to allow the second lead screw 107 to rotate forward or backward. During rotation, the movable frame 105 moves horizontally and slides on the guide rod 104 to improve stability. This horizontal movement further drives the electric push rod 106 and the cleaning connection mechanism 2, allowing the filter shovel 201 to move horizontally. This enables the collection of scum from the treatment tank body 101. Furthermore, with the assistance of the electric push rod 106, the scum is collected according to the treatment requirements. The position of the wastewater depth adjustment filter shovel 201 in the main body of the treatment tank 101 is adjusted. After collection, when it is necessary to process the scum collected by the filter shovel 201, the filter shovel 201 is moved to the position corresponding to the opening 109. Then, the two baffles 202 are pulled upwards, and the dual-axis motor 208 is turned on through the control panel 103. When turned on, the first lead screw 206 can rotate forward or backward. When rotating, it drives the slider 207 to slide in the first slide groove 205 and the second slide groove 203, so that the cleaning plate 209 can push the scum in the filter shovel 201 and push it out of the filter shovel 201 through the opening 109.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
