The stirring device is installed in the main treatment tank.

[0009] Furthermore, the secondary processing box is provided with a second blocking member, which abuts against the filter plate.

[0010] Furthermore, the filter plate is provided with a handle at the top.

[0011] Furthermore, the sealing cap is equipped with a wrench.

[0012] Furthermore, the stirring device includes a motor, an output column, several stirring rods, a connecting rod, and a stirring cylinder; the motor is installed in the main processing box, the output column is connected to the output end of the motor, the stirring rods are fixedly connected to the output column, the connecting rods are fixedly connected to the output column, the stirring cylinder is pivotally connected to the connecting rod, and the stirring cylinder is provided with several stirring holes.

[0013] Beneficial effects:

[0014] This invention provides a wastewater treatment device. In use, a filter plate is inserted between a main treatment tank and a secondary treatment tank. Wastewater enters the secondary treatment tank through an inlet pipe, is filtered by the filter plate, and then enters the main treatment tank. Chemicals are added to the main treatment tank through a dosing pipe, and a stirring mechanism is activated to react the wastewater and chemicals. After treatment, the wastewater is discharged through a drain pipe, and the settled sludge flows into a sludge discharge pipe through a chute. The sludge can be discharged by opening the sealing cover, facilitating sludge removal. Because the filter plate is inserted and removed from the top of the main treatment tank without water pressure, the sealing performance is good. Therefore, this wastewater treatment device is less prone to wastewater leakage at the connection between the filter plate and the treatment tank, and the bottom sludge is easy to handle.

[0030] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] This embodiment provides a wastewater treatment device; please refer to [reference needed]. Figure 1-4 As shown, the system includes a main treatment tank 100, a secondary treatment tank 200, a filter plate 300, and a stirring device 400. The secondary treatment tank 200 is welded to the main treatment tank 100 and is connected to an inlet pipe 210. The main treatment tank 100 has a chute 110 at its bottom. The main treatment tank 100 is connected to a first blocking member 120, a dosing pipe 130, an outlet pipe 140, and a sludge discharge pipe 150. The first blocking member 120 is welded inside the main treatment tank 100, the dosing pipe 130 is welded to the top of the main treatment tank 100, the outlet pipe 140 is welded to one side of the main treatment tank 100 and is located above the chute 110, and the sludge discharge pipe 150 is welded to the bottom of the main treatment tank 100 and is threadedly connected to a sealing cap 160. The filter plate 300 is disposed between the main treatment tank 100 and the secondary treatment tank 200 and abuts against the first blocking member 120. The stirring device 400 is installed in the main treatment tank 100.

[0032] Specifically, the main treatment tank 100 provides space for wastewater treatment, the chute 110 allows settled sludge to slide into the sludge discharge pipe 150, the dosing pipe 130 adds chemicals to the main treatment tank 100, the effluent pipe 140 discharges the wastewater that has undergone chemical reaction to the next wastewater treatment unit, the sludge discharge pipe 150 discharges the settled sludge from the main treatment tank 100, and the sealing cap 160 seals the sludge discharge pipe 150 to prevent sludge from flowing out. When sludge needs to be discharged, the sealing cap is unscrewed. 160 is sufficient. The first blocking component 120 is used to prevent the filter plate 300 from sliding into the main treatment tank 100. The secondary treatment tank 200 is a transition device for adding sewage to the main treatment tank 100, and also prevents sewage from flowing out at the connection between the filter plate 300 and the main treatment tank 100 and the secondary treatment tank 200. The filter plate 300 is used to filter impurities in the sewage and prevent impurities from entering the main treatment tank 100. The inlet pipe 210 is used to add sewage into the secondary treatment tank 200. The stirring device 400 is used to make the sewage and the chemical solution react fully. In use, the filter plate 300 is inserted between the main treatment tank 100 and the auxiliary treatment tank 200. Wastewater enters the auxiliary treatment tank 200 through the inlet pipe 210, and after being filtered by the filter plate 300, it enters the main treatment tank 100. Chemicals are added to the main treatment tank 100 through the dosing pipe 130, and the stirring device 400 is started to react the wastewater and the chemicals. After treatment, the wastewater is discharged through the outlet pipe 140, and the settled sludge flows into the sludge discharge pipe 150 through the chute 110. The sludge can be discharged by opening the sealing cover 160, which facilitates the discharge of sludge. Since the filter plate 300 is inserted and removed from the top of the main treatment tank 100, there is no water pressure, so the sealing performance is good.

[0033] In this embodiment, the secondary processing box 200 is provided with a second blocking member 220, which abuts against the filter plate 300.

[0034] Specifically, the first blocking member 120 and the second blocking member 220 cooperate to ensure stable insertion and removal of the filter plate 300.

[0035] In this embodiment, a handle 310 is provided on the top of the filter plate 300.

[0036] Specifically, the handle 310 is fixedly connected to the filter plate 300, making it convenient for operators to insert and remove the filter plate 300.

[0037] In this embodiment, the sealing cap 160 is provided with a wrench 161.

[0038] Specifically, there are four wrenches 161, which are welded to the sealing cover 160 to facilitate the installation and removal of the sealing cover 160 by the operators.

[0039] In this embodiment, the stirring device 400 includes a motor 410, an output column 420, a plurality of stirring rods 430, a connecting rod 440, and a stirring cylinder 450. The motor 410 is installed in the main processing box 100, the output column 420 is connected to the output end of the motor 410, the stirring rods 430 are fixedly connected to the output column 420, the connecting rod 440 is fixedly connected to the output column 420, the stirring cylinder 450 is pivotally connected to the connecting rod 440, and the stirring cylinder 450 is provided with a plurality of stirring holes 451.

[0040] Specifically, the stirring device 400 is used to ensure that the wastewater and the medicine react fully, thereby reducing sludge sedimentation. The motor 410 drives the output column 420 to rotate, which in turn drives the stirring rod 430 and the connecting rod 440 to rotate. The stirring drum 450 rotates on the connecting rod 440 and also rotates with the connecting rod 440, thereby improving the stirring efficiency of the wastewater and the medicine. The stirring hole 451 is used to increase the flow direction of the wastewater and improve the reaction efficiency between the medicine and the wastewater.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
