Description

Technical Field

[0001] This utility model belongs to the field of sludge dewatering technology, and in particular, it is a device for dewatering sludge from the tailwater of a waterworks. Background Technology

[0002] The main components of wastewater treatment plant effluent include inorganic pollutants, organic pollutants, and heavy metals from the raw water. These pollutants mainly originate from impurities in the raw water, the use of coagulants, and sediments generated during water treatment. Currently, most wastewater effluent sludge from water treatment plants is dewatered using centrifugal force. While centrifugal dewatering can improve the dewatering effect, the rotation of the centrifuge drum causes a large amount of sludge to clog the mesh, making it difficult to clean.

[0003] A search revealed a Chinese patent document (authorization announcement number CN118579972A) for a dewatering treatment device for sludge from waterworks effluent. The device includes a treatment tank, a feed pipe, and a centrifuge tank. The treatment tank contains a drive assembly to control the rotation of the centrifuge tank. Inside the centrifuge tank is a treatment cylinder with a piston slidably mounted inside. A suction pipe with a water inlet is located at the bottom of the treatment cylinder. While this device can effectively dewater the sludge and further reduce its water content, in actual use, the centrifugal force causes some sludge to be squeezed into the mesh and cannot be cleaned. The device's scraping method is insufficient to remove the sludge from the mesh. Therefore, a new sludge dewatering device for waterworks effluent is urgently needed to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a dewatering device for sludge from waterworks tailwater to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a waterworks tailwater sludge dewatering device, comprising a base plate for installing a waterworks tailwater sludge dewatering structure and a dewatering frame for waterworks tailwater sludge dewatering, wherein two vertical plates are symmetrically and fixedly installed on the top surface of the base plate, and a horizontal plate is fixedly installed between the two vertical plates.

[0006] The dehydration frame is slidably installed between two horizontal plates, and sliders are symmetrically fixedly installed on the side walls of the horizontal plates. The side walls of the horizontal plates are provided with sliding grooves, and the sliders are slidably inserted into the inside of the sliding grooves.

[0007] The top surface of the dehydration frame has a strip-shaped hole, and a dehydration plate is slidably installed in the strip-shaped hole. Multiple baffles are fixedly installed on one side of the dehydration frame, and a filter screen is installed on the inner wall of the dehydration frame.

[0008] A squeezing plate is slidably installed on the inner wall of the dehydration frame, and a connecting rod is fixedly installed on one side of the squeezing plate, with a connecting plate fixedly installed at the end of the connecting rod.

[0009] Preferably, a plurality of rectangular blocks are fixedly installed on the side wall of the extrusion plate, and rectangular grooves are opened on the inner wall of the dehydration frame corresponding to the rectangular blocks.

[0010] Preferably, the multiple rectangular blocks fixedly installed on the side wall of the extrusion plate are slidably inserted into the interior of the rectangular groove opened on the inner wall of the dehydration frame.

[0011] Preferably, limit blocks are symmetrically fixedly installed on the sidewalls of the slider, and limit grooves are symmetrically formed on the inner wall of the slide.

[0012] Preferably, the two limiting blocks fixedly installed on the side wall of the slider are slidably connected to the inside of the limiting groove opened in the inner wall of the slide.

[0013] Preferably, a sealing gasket is fixedly bonded to the outer wall of the dehydration plate, and the outer wall of the sealing gasket slides against the inner wall of the dehydration frame.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0015] This waterworks tailwater sludge dewatering device benefits from the structure of the dewatering frame, the extrusion plate and the dewatering plate. After the sludge is fed into the dewatering frame through the feed pipe, the hydraulic cylinder pushes the extrusion plate into the dewatering frame to squeeze and dewater the sludge. At this time, the dewatering plate and the filter screen will filter the sludge. The dewatered sludge will be squeezed into a cake, which can quickly dewater the sludge.

[0016] The sludge dewatering device for the tailwater of this waterworks benefits from the design of the strip holes and the dewatering plate. After dewatering is completed, the connecting plate can be moved to move the squeezing plate out of the dewatering frame, which makes it easier to remove the sludge cake inside. At the same time, the dewatering plate can be pulled out through the strip holes, which allows for cleaning of the dewatering plate.

[0017] The sludge dewatering device for the tailwater of this waterworks benefits from the design of horizontal plates, sliders and chutes, which allows multiple sets of dewatering frames to be installed between two horizontal plates. These multiple sets of dewatering frames can simultaneously dewater a large amount of sludge, thereby improving the sludge dewatering efficiency.

[0018] Compared with existing technologies, this waterworks tailwater sludge dewatering device can effectively dewater sludge while also facilitating the discharge of dewatered sludge and cleaning of the dewatering plate. Attached Figure Description

[0025] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0027] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0028] like Figures 1 to 3The main structure of the waterworks effluent sludge dewatering device shown is a base plate 1 for installing the waterworks effluent sludge dewatering structure and a dewatering frame 6 for dewatering the waterworks effluent sludge. Two vertical plates 2 are symmetrically fixedly installed on the top surface of the base plate 1, and a horizontal plate 3 is fixedly installed between the two vertical plates 2. The length of the two horizontal plates 3 is relatively long, while the width of the dewatering frame 6 and other structures is much smaller than the length of the horizontal plates 3. The dewatering frame 6 is slidably installed between the two horizontal plates 3, and sliders 12 are symmetrically fixedly installed on the side walls of the horizontal plates 3. The side walls of the horizontal plates 3 are provided with grooves, and the sliders 12 are slidably inserted into the interior of the grooves. Thanks to the design of the horizontal plates 3, sliders 12 and grooves, multiple sets of dewatering frames 6 can be installed between the two horizontal plates 3. Multiple sets of dewatering frames 6 can simultaneously dewater a large amount of sludge, thereby improving the sludge dewatering efficiency.

[0029] A hydraulic cylinder 4 is fixedly installed on the outer side of one of the vertical plates 2. The telescopic end of the hydraulic cylinder 4 slides to the other side of the vertical plate 2 and a movable plate 5 is fixedly installed thereon. The movable plate 5 is matched with the connecting plate 14.

[0030] The top surface of the dehydration frame 6 is provided with a strip-shaped hole 7, and a dehydration plate 8 is slidably installed in the strip-shaped hole 7. Multiple baffles 9 are fixedly installed on one side of the dehydration frame 6, and a filter screen 10 is installed on the inner wall of the dehydration frame 6. After the dehydration plate 8 is inserted into the dehydration frame 6, one side of the dehydration plate 8 will contact the multiple baffles 9, thereby limiting the position of the dehydration plate 8 through the multiple baffles 9, thereby further improving the stability of the dehydration plate 8.

[0031] A squeezing plate 11 is slidably installed on the inner wall of the dehydration frame 6, and a connecting rod 13 is fixedly installed on one side of the squeezing plate 11. The end of the connecting rod 13 connected to the squeezing plate 11 is flared. The flared connecting rod 13 can evenly distribute the force on the side wall of the squeezing plate 11, thereby further improving the stability of the squeezing plate 11 in the dehydration frame 6. A connecting plate 14 is fixedly installed at the end of the connecting rod 13.

[0032] Multiple rectangular blocks 15 are fixedly installed on the side wall of the extrusion plate 11. Rectangular grooves are opened on the inner wall of the dehydration frame 6 corresponding to the rectangular blocks 15. The multiple rectangular blocks 15 fixedly installed on the side wall of the extrusion plate 11 are slidably inserted into the interior of the rectangular grooves opened on the inner wall of the dehydration frame 6. The rectangular blocks 15 can effectively limit the sliding direction of the extrusion plate 11 and further improve the stability of the extrusion plate 11 when sliding.

[0033] Limiting blocks 16 are symmetrically fixedly installed on the side wall of slider 12, and limiting grooves are symmetrically opened on the inner wall of the slide. The two limiting blocks 16 fixedly installed on the side wall of slider 12 are slidably connected to the inside of the limiting grooves opened on the inner wall of the slide. The limiting blocks 16 can further improve the stability of slider 12 and dewatering frame 6 when sliding along the horizontal plate 3.

[0034] A sealing gasket 18 is fixedly bonded to the outer wall of the dewatering plate 8, and the outer wall of the sealing gasket 18 slides against the inner wall of the dewatering frame 6. The sealing gasket 18 can effectively improve the sealing effect between the dewatering plate 8 and the inner wall of the dewatering frame 6, thereby preventing sludge from leaking out from the gap between the dewatering frame 6 and the dewatering plate 8.

[0035] Working principle

[0036] In use, the sludge dewatering device for the wastewater treatment plant first feeds the sludge into the dewatering frame 6 through multiple feed pipes 17. Then, the hydraulic cylinder 4 is activated, which pushes the movable plate 5 installed at its end to move towards the connecting plate 14. The connecting plate 14 pushes the connecting rod 13 and the extrusion plate 11 installed on its side wall into the dewatering frame 6. The extrusion plate 11 extrudes and dewaters the sludge. After dewatering, the connecting plate 14 is moved to move the connecting rod 13 and the extrusion plate 11 out of the dewatering plate 8. This makes it easy to remove the dewatered sludge cake. At the same time, the dewatering plate 8 can be pulled out and cleaned through the strip hole 7 on the top surface of the dewatering frame 6.
