Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically to a filter press device for sludge in sedimentation tanks. Background Technology

[0002] The sludge press filter is a solid-liquid separation device used to squeeze out water from sludge, reducing its volume and facilitating subsequent treatment or disposal. The core of the filter press is to forcibly separate water from the sludge using mechanical pressure. During the filtration process, the sludge pump sends the sludge from the sedimentation tank into the filter press, which consists of filter plates and filter cloth. The filter plates are pressed tightly, and the sludge is squeezed under high pressure. Water passes through the filter cloth and is discharged, while solid particles are trapped to form a sludge cake. The micropores of the filter cloth allow water molecules to pass through but block solid sludge particles. After the filtration is completed, the filter plates are released, the sludge cake falls off automatically, and is collected and transported for disposal.

[0003] Existing filter press devices for sludge in sedimentation tanks require a plate-pulling mechanism to pull the filter plates apart sequentially after the filter press operation is completed, so that the filter cake falls off. Each time the plate-pulling mechanism completes a "grab-move-release" cycle, it can only pull apart one filter plate, and then returns to the starting position. This process is repeated until all filter plates are pulled apart, which takes a long time and affects the overall production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a filter press device for sludge in sedimentation tanks, in order to solve the problem mentioned in the background art that the existing filter press devices for sludge in sedimentation tanks require a plate pulling mechanism to pull the filter plates one by one after the filter press operation is completed, so that the filter cake falls off. Each time the plate pulling mechanism completes a "grab-move-release" cycle, it can only pull open one filter plate, and then returns to the starting position. This process is repeated until all filter plates are pulled open, which takes a long time and affects the overall production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter press device for sludge in sedimentation tanks, comprising a frame, a filter press section, and a drive section:

[0006] The filter press is located inside the frame and has several filter plates that are slidably disposed inside the frame. A telescopic rod is provided at the top of the frame, and the bottom of the telescopic rod is connected to the filter plates. When one filter plate moves, it causes the telescopic rod to extend or retract, thereby displacing all the filter plates. The drive unit is located on the side of the frame and has a connecting frame located on the side of the frame. A slide is slidably disposed inside the connecting frame and is connected to the outermost filter plate. The displacement of the slide causes the filter plate to move.

[0007] By adopting the above technical solution, the filter press plates can be moved by the slide of the drive unit, and at the same time, the linkage of the telescopic rod can be used to make multiple filter press plates move synchronously, thereby improving the efficiency of filter cake removal.

[0008] Preferably, the frame has a slide bar disposed inside the frame, and a slide groove is provided on the side of each of the filter plates. The slide bar passes through the slide groove laterally and is slidably connected to the filter plate laterally. An extrusion plate is slidably disposed inside the frame, and a hydraulic rod is disposed on the side of the frame. The output end of the hydraulic rod is connected to the extrusion plate, and the extrusion plate abuts against the filter plate.

[0009] By adopting the above technical solution, the filter press plate can be stably slid within the frame through the cooperation of the slide bar and the slide groove. At the same time, the hydraulic rod pushes the extrusion plate to apply pressure to the filter press plate, thereby enhancing the sludge filtration effect.

[0010] Preferably, the filter press also has a connecting shaft b disposed at the bottom of the telescopic rod. The telescopic rod is a mechanical structure that achieves horizontal extension and retraction through the unfolding and folding of cross links. Several connecting shafts a are arranged at the cross positions at the bottom of the telescopic rod.

[0011] By adopting the above technical solution, a stable and uniform horizontal telescopic movement can be achieved through the cross-link structure of the telescopic rod under the action of connecting shaft a and connecting shaft b, ensuring that multiple filter plates move synchronously.

[0012] Preferably, the filter press also has a connecting groove b formed on the top of the filter press plate, and the connecting shaft a is embedded in the connecting groove b and rotatably connected to the filter press plate.

[0013] By adopting the above technical solution, the filter press plate can be moved smoothly during the extension and retraction process by rotating the connecting shaft a and the connecting groove b.

[0014] Preferably, the frame also has a connecting groove a on the top of the frame, and the connecting shaft b is embedded in the connecting groove a and rotatably connected to the frame.

[0015] By adopting the above technical solution, the telescopic rod can be stably fixed on the frame through the rotatable connection between the connecting shaft b and the connecting groove a.

[0016] Preferably, the drive unit also has a slot provided on the side of the carriage, and the carriage is provided with two slots, which engage with the two sides of the filter press plate.

[0017] By adopting the above technical solution, the slide can firmly drive the filter plate to move through the snap-fit ​​of the slot and the filter plate, preventing the filter plate from shifting or loosening during the movement.

[0018] Preferably, the drive unit has two lead screws rotatably disposed inside the connecting frame, each of which passes laterally through two slides and is nested and threadedly connected to the two slides.

[0019] By adopting the above technical solution, the displacement of the filter press plate can be precisely controlled by rotating the lead screw to drive the slide to move laterally along the lead screw.

[0020] Preferably, the drive unit also has a bevel tooth a at one end of the lead screw, a power shaft is rotatably arranged inside the connecting frame, two bevel teeth b are arranged on the side of the power shaft, the two bevel teeth b are respectively meshed with the two bevel teeth a, and a motor is arranged on the side of the connecting frame, the output end of the motor is connected to the power shaft.

[0021] By adopting the above technical solution, the power shaft can be rotated by a motor, and the meshing transmission of bevel teeth a and b can make the two lead screws rotate synchronously, thereby ensuring that the two carriages move synchronously.

[0022] Compared with the prior art, the beneficial effects of this utility model are: by providing a filter pressing part and a driving part, the filter pressing plate can be moved by the slide of the driving part, and at the same time, the linkage of the telescopic rod can be used to make multiple filter pressing plates move synchronously, thereby improving the efficiency of filter cake falling off.

A telescopic rod 204 is provided on the top of the frame 1. The bottom of the telescopic rod 204 is connected to the filter press plates 201.

The drive unit 3 has a connecting frame 301 located on the side of the frame 1. A slide 307 is slidably disposed laterally inside the connecting frame 301.

At the same time, the linkage of the telescopic rod 204 can make multiple filter press plates 201 move synchronously, improving the efficiency of filter cake removal. The core of the filter press device is to forcibly separate water from sludge through mechanical pressure. The above is the prior art and will not be described in detail below.

[0034] Example 2

[0035] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a filter press device for sludge in a sedimentation tank, comprising a filter press section 2, a filter press plate 201, and a telescopic rod 204.

[0036] A slide rod 101 is fixedly installed inside the frame 1. The fixing method is an existing detachable fixing method, such as bolt connection, snap connection, etc. Several filter plates 201 have sliding grooves 202 on their sides. The slide rod 101 passes through the sliding grooves 202 laterally and slides laterally with the filter plates 201. An extrusion plate 103 is slidably installed inside the frame 1. A hydraulic rod 104 is installed on the side of the frame 1. The output end of the hydraulic rod 104 is connected to the extrusion plate 103. The extrusion plate 103 abuts against the filter plates 201. Through the cooperation of the slide rod 101 and the sliding grooves 202, the filter plates 201 can slide stably inside the frame 1. At the same time, the hydraulic rod 104 pushes the extrusion plate 103 to apply pressure to the filter plates 201, thereby enhancing the sludge filtration effect.

[0037] A connecting shaft b206 is provided at the bottom of the telescopic rod 204. The telescopic rod 204 is a mechanical structure that achieves horizontal telescopic movement by unfolding and folding cross links. Several connecting shafts a205 are arranged at the cross position at the bottom of the telescopic rod 204. Through the cross link structure of the telescopic rod 204, under the action of the connecting shafts a205 and b206, a stable and uniform horizontal telescopic movement can be achieved, ensuring that multiple filter plates 201 move synchronously.

[0038] A connecting groove b203 is provided on the top of the filter press plate 201. The connecting shaft a205 is embedded in the connecting groove b203 and is rotatably connected to the filter press plate 201.

[0039] A connecting groove a102 is provided on the top of the frame 1. The connecting shaft b206 is embedded in the connecting groove a102 and rotatably connected to the frame 1. The telescopic rod 204 can be stably fixed on the frame 1 through the rotatable connection between the connecting shaft b206 and the connecting groove a102.

[0040] Example 3

[0041] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a filter press device for sludge in a sedimentation tank, comprising a drive unit 3, a connecting frame 301, and a slide 307.

[0042] The slide 307 has two slots 308 on its side. The two slots 308 engage with the two sides of the filter press plate 201. The engagement of the slots 308 with the filter press plate 201 allows the slide 307 to firmly move the filter press plate 201, preventing the filter press plate 201 from shifting or loosening during movement.

[0043] Inside the connecting frame 301, there is a rotatable lead screw 302. There are two lead screws 302. The two lead screws 302 pass laterally through the two slides 307 and are nested and threadedly connected to the two slides 307. The rotation of the lead screw 302 can drive the slides 307 to move laterally along the lead screw 302, thereby precisely controlling the displacement of the filter press plate 201.

[0044] A bevel tooth a303 is integrally provided at one end of the lead screw 302. A power shaft 304 is rotatably provided inside the connecting frame 301. Two bevel teeth b305 are provided on the side of the power shaft 304. The two bevel teeth b305 are respectively meshed with the two bevel teeth a303. A motor 306 is provided on the side of the connecting frame 301. The output end of the motor 306 is connected to the power shaft 304. The motor 306 can drive the power shaft 304 to rotate. By utilizing the meshing transmission of bevel teeth a303 and bevel teeth b305, the two lead screws 302 rotate synchronously, thereby ensuring that the two slides 307 move synchronously.

[0045] Working principle: First, the sludge pump sends the sludge from the sedimentation tank into the filter chamber composed of filter plates 201. The filter plates 201 are pressed tightly, and the sludge is squeezed under high pressure. Water passes through the filter cloth and is discharged, while solid particles are trapped to form a sludge cake. The micropores of the filter cloth allow water molecules to pass through but block solid sludge particles. After filtration is completed, the motor 306 of the drive unit 3 starts, driving the power shaft 304 to rotate. The bevel tooth b305 on the power shaft 304 meshes with the bevel tooth a303 at the end of the lead screw 302, causing the two lead screws 302 to rotate synchronously. Since the slide 307 is threadedly connected to the lead screw 302, the rotation of the lead screw 302 will drive the two slides 307 to move laterally along the connecting frame 301. At the same time, the slide 307 is engaged with the outermost filter plate 201 through the slot 308, driving the filter plate 201 to move along the slide rod 101. The filter press plates 201 slide, and since all the filter press plates 201 are linked by the telescopic rods 204, when one filter press plate 201 moves, the cross linkage structure of the telescopic rods 204 unfolds under the action of the connecting shafts a205 and b206, so that all the filter press plates 201 move and unfold synchronously, allowing the dewatered filter cake to fall off the filter press plates 201.
