The wastewater flows relatively stably upward within the S-shaped flow channel. During the wastewater flow, the sludge and sand inside adhere to the various inclined surfaces. The inclined channel surface increases the contact area with the wastewater and can relatively actively contact the suspended sludge and sand layers in the wastewater, quickly and efficiently settling the sludge and sand during the continuous flow of wastewater.

Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a high-efficiency sludge removal device for industrial wastewater. Background Technology

[0002] Industrial wastewater includes production wastewater, industrial sewage, and cooling water. It refers to the wastewater and waste liquid generated during industrial production processes, which contain industrial production materials, intermediate products, by-products, and pollutants generated during production that are lost with the water. Industrial wastewater treatment refers to the proper treatment of water used in industrial production processes for reuse in production or proper discharge from the factory. This includes the management of production water and measures taken to facilitate wastewater treatment.

[0003] The most common method for removing sludge from industrial wastewater is sedimentation. This involves either letting the wastewater settle, which takes a long time and is not very efficient, or controlling the wastewater to flow slowly and steadily so that the sludge particles can settle naturally. However, since the wastewater is flowing, the sedimentation effect is not very good. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency sludge removal device for industrial wastewater to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency sludge removal device for industrial wastewater includes:

[0007] The sludge removal structure includes a sedimentation tank, wherein a flow channel is provided inside the sedimentation tank;

[0008] A sealing structure is embedded on one side of the sedimentation tank;

[0009] The sludge discharge structure includes a pusher plate, which is movably engaged with the inner wall of the other side of the sedimentation tank.

[0010] Furthermore, an inlet is fixedly installed on the lower front edge of the sedimentation tank, and an outlet is fixedly installed on the upper rear edge of the sedimentation tank.

[0011] Furthermore, a sludge outlet is provided on one side of the sedimentation tank, and a sealing groove is provided at the edge of the sludge outlet.

[0012] Furthermore, the sealing structure includes:

[0013] A sealing plate is attached to the sludge outlet.

[0014] The inner panel is fixedly installed on the inner surface of the sealing plate;

[0015] A sealing clip frame is fixedly installed on the inner edge of the sealing plate;

[0016] A sealing sleeve is fixedly fitted onto the side surface of the sealing clip frame;

[0017] A connecting rod is fixedly installed on the inner surface of the inner plate, and the other end of the connecting rod is fixedly connected to the push plate.

[0018] Furthermore, the sealing structure also includes:

[0019] Auxiliary support plate is fixedly installed on the lower edge of the outer surface of the sealing plate;

[0020] The wheels are fixedly installed at the bottom of the auxiliary support plate.

[0021] Furthermore, a base frame is fixedly installed on one side surface of the sedimentation tank, an integrated plate is slidably fitted inside the base frame, a hydraulic rod is inserted and installed on one side of the base frame, the output end of the hydraulic rod is fixedly connected to the integrated plate, an auxiliary support foot is fixedly installed on one side edge of the bottom of the base frame, and a push rod is fixedly installed on one side of the integrated plate, the push rod passes through the sedimentation tank and is fixedly connected to the push plate.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. Wastewater is slowly introduced into the sedimentation tank from the bottom, and discharged from the top of the sedimentation tank after passing through the flow channel. The flow channel is designed with a multi-S-shaped structure and a slope of only ten degrees, combining vertical flow sedimentation and horizontal flow sedimentation. The wastewater flows relatively stably upward in the S-shaped flow channel. During the flow of wastewater, the sediment inside is deposited and adheres to each slope. The inclined channel surface increases the contact area with the wastewater and can relatively actively contact the suspended sediment layers in the wastewater. Combined with the sedimentation phenomenon of the sediment itself in the water, the sediment can be quickly and efficiently settled during the continuous flow of wastewater. The sediment deposited on the slope of the flow channel is scraped away by the push plate.

[0024] 2. During maintenance and cleaning, the entire sludge removal structure stops working. The hydraulic rod is activated to push the integrated plate, and then each push rod pushes the push plate to slide inside the sedimentation tank, pushing out all the sludge and sand from the inner wall of the flow channel. At the same time, the connecting rod pushes the inner plate and sealing plate away from the sludge outlet, pushing the push plate, inner plate, sealing plate and all the sludge and sand to the outside of the sedimentation tank, making it convenient for staff to clean directly.

[0032] Specifically, wastewater is slowly introduced from the bottom of sedimentation tank 101, passes through flow channel 104, and is discharged from the top of sedimentation tank 101. Flow channel 104 is designed with a multi-S-shaped structure and a slope of only ten degrees, combining vertical flow sedimentation and horizontal flow sedimentation. Wastewater flows relatively stably upward in the S-shaped flow channel 104. During the wastewater flow, the sediment inside adheres to the various inclined surfaces. The inclined channel surface increases the contact area with wastewater and can relatively actively contact the suspended sediment layers in the wastewater. Combined with the sedimentation phenomenon of the sediment itself in the water, the sediment can be quickly and efficiently settled during the continuous flow of wastewater. The sediment deposited on the inclined surface of flow channel 104 is scraped away by push plate 306.

[0037] In practice, a pleated structure is formed at the edge of the sealing plate 201 by the sealing plate 201, the inner plate 202 and the sealing frame 203, and embedded in the sealing groove 106. The sealing sleeve 204 is used to ensure sufficient sealing effect so as to ensure the normal operation of the sedimentation tank 101.

[0041] In practice, during maintenance and cleaning, the entire sludge removal structure 1 stops working, the hydraulic rod 303 is activated to push the integrated plate 302, and then each push rod 305 pushes the push plate 306 to slide inside the sedimentation tank 101, pushing out all the sludge and sand on the inner wall of the flow channel 104. At the same time, the connecting rod 205 pushes the inner plate 202 and the sealing plate 201 away from the sludge outlet 105, pushing the push plate 306, the inner plate 202, the sealing plate 201, and all the sludge and sand to the outside of the sedimentation tank 101, making it convenient for staff to clean directly.
