Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment filtration device. Background Technology

[0002] Wastewater treatment refers to the purification process of treating wastewater to meet the requirements of a certain water body or making it reusable. People's lives generate a large amount of wastewater, and if this wastewater is discharged directly without treatment, it will cause serious pollution to the environment.

[0003] During the filtration and interception process of sewage, a lot of debris will accumulate, resulting in unsatisfactory filtration effect. The conventional cleaning method is to manually clean it after the sewage filtration is stopped, which is not only time-consuming and labor-intensive, but also affects the normal filtration of sewage. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a wastewater treatment filtration device to solve the problems mentioned in the background section.

[0005] A wastewater treatment filtration device includes a filter tank and a filtration cleaning mechanism installed on the filter tank. The filtration cleaning mechanism includes filter plates, retrieval plates, hook plates, a motor, a drive shaft, a loading plate, and a support platform. Multiple filter plates are evenly arranged at the bottom of the filter tank. The motor is installed on one side plate of the filter tank. The drive shaft is fixed to the output end of the motor. At least one set of retrieval plates is fixed to the motor, with multiple plates in each set, staggered and corresponding to the multiple filter plates. Multiple hook plates are fixed one-to-one to the bottom of the retrieval plates. Two support platforms are installed opposite each other on both sides of the filter tank. The loading plate can slide along the support platform.

[0006] By adopting the above technical solution, the device facilitates the cleaning of debris intercepted by the filter plate, preventing debris from accumulating excessively on one side of the filter plate and affecting the normal filtration and flow of sewage.

[0007] One side of the filter plate is also provided with a reinforcing plate that is fixedly connected to the filter tank.

[0008] By adopting the above technical solution, the stability of the filter plate is enhanced.

[0009] The width of the retrieval plate is set to be smaller than the gap between the filter plates.

[0010] By adopting the above technical solution, it is possible for the retrieval plate and hook plate to pass through the gaps in the filter plate.

[0011] The hook plate has an arc-shaped structure and is set with the drive shaft as the center. Its outer edge can fit into the surface of the middle part of the filter tank.

[0012] By adopting the above technical solution, the debris can be salvaged.

[0013] The length of the loading plate is set to be greater than the width of the filter tank.

[0014] By adopting the above technical solution, it is possible to move the loading plate to the middle of the filter tank and remove the debris from the retrieval plate and hook plate.

[0015] The beneficial effects of the wastewater treatment filtration device of this utility model are:

[0016] When wastewater passes through the filter tank, debris is intercepted by the filter plates. Once a certain amount of debris accumulates, a drive motor rotates the scooping plate and the arc-shaped plate via a transmission shaft. The scooping plate and the arc-shaped plate pass through the gaps between the filter plates. With the assistance of the arc-shaped plate, debris on one side of the filter plates is scooped up. The scooping plate and the arc-shaped plate continue to rotate, carrying the debris to the upper side of the filter tank. The length of the loading plate is set to be greater than the width of the filter tank. This device facilitates the cleaning of debris intercepted by the filter plates, preventing excessive accumulation of debris on one side of the filter plates and affecting the normal filtration and flow of wastewater.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0022] Reference Figure 1-3A wastewater treatment filtration device includes a filter tank 1 and a filtration cleaning mechanism installed on the filter tank 1. The filtration cleaning mechanism includes filter plates 2, retrieval plates 4, arc plates 5, a motor 6, a drive shaft 7, a loading plate 8, and a support platform 9. There are multiple filter plates 2, which are evenly arranged at the bottom of the filter tank 1. The motor 6 is installed on one side plate of the filter tank 1. The drive shaft 7 is fixed at the output end of the motor 6. There is at least one set of retrieval plates 4, which are fixed on the motor 6. Each set has multiple plates, which are staggered and corresponding to the multiple filter plates 2. There are multiple arc plates 5, which are fixed one-to-one to the bottom of the retrieval plates 4. There are two support platforms 9 installed opposite each other on both sides of the filter tank 1. The loading plate 8 can slide along the support platform 9.

[0023] When wastewater passes through filter tank 1, debris is intercepted by filter plates 2. After a certain amount of debris accumulates, motor 6 drives the retrieval plate 4 and arc plate 5 to rotate via transmission shaft 7. The retrieval plate 4 and arc plate 5 can pass through the gap between filter plates 2. With the assistance of arc plate 5, debris on one side of filter plate 2 is retrieved. The retrieval plate 4 and arc plate 5 continue to rotate, bringing the debris to the upper side of filter tank 1. The length of loading plate 8 is set to be greater than the width of filter tank 1. At this time, loading plate 8 can be pushed to push one end of loading plate 8 onto the support platform 9 on the other side of filter tank 1. The debris retrieved by retrieval plate 4 and arc plate 5 can then be manually cleaned onto loading plate 8. After cleaning, loading plate 8 can be pulled back to clean the debris off loading plate 8.

[0024] This device facilitates the cleaning of debris intercepted by the filter plate 2, preventing debris from accumulating excessively on one side of the filter plate 2 and affecting the normal filtration and flow of wastewater.

[0025] A reinforcing plate 3 is also provided on one side of the filter plate 2 and is fixedly connected to the filter tank 1. The reinforcing plate 3 is a trapezoidal structure, and its right-angled side is fixedly connected to one side of the filter plate 2. The filter plate 2 can intercept the debris on the other side of the filter plate 2 so that the retrieval plate 4 and the arc plate 5 can pass through the gap of the filter plate 2 to retrieve the debris.

[0026] The width of the retrieval plate 4 is set to be smaller than the gap between the filter plates 2, so that the retrieval plate 4 and the arc plate 5 can pass through the gap between the filter plates 2 to retrieve the debris.

[0027] The arc plate 5 has an arc-shaped structure and is set with the drive shaft 7 as the center. Its outer edge can fit with the surface of the middle part of the filter tank 1. The width of the arc plate 5 is the same as the width of the retrieval plate 4. After the arc plate 5 passes through the gap of the filter plate 2, it can retrieve the debris on the other side of the filter plate 2. The length of the loading plate 8 is set to be greater than the width of the filter tank 1.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
