Description

Technical Field

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

[0002] Sludge treatment is a process of reducing, stabilizing, and rendering harmless sludge by means of concentration, conditioning, dewatering, stabilization, drying, or incineration.

[0003] A search of patent document CN221644764U reveals "a sludge filter press treatment device. During operation, this device monitors the surface of the filter plates using a camera to determine if any residue remains. This allows for cleaning of the filter plates. A first motor drives a control plate to rotate, which in turn rotates a rotating plate, controlling its angle. A second motor drives a pusher plate to slide, pressing the rotating plate downwards, causing scrapers and exhaust ports to blow away and remove residual residue from the filter plate surface."

[0004] When the above-mentioned device is in operation, although it can scrape off the residual mud on the filter plate with a scraper, the filter cloth or mesh structure on the filter plate is mostly made of flexible material. When the scraper of the above-mentioned device cleans the filter cloth on the filter plate, it can easily cause scratches on the filter cloth structure, thus requiring the device to be suspended for maintenance. Utility Model Content

[0005] The purpose of this invention is to provide a sludge dewatering device to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A sludge depressurization treatment device includes a support frame, multiple filter plates are slidably connected inside the support frame, a water guiding mechanism is installed below the filter plates, and a sludge discharge mechanism is also included.

[0008] The sludge removal mechanism includes a screw, which is located in front of the filter plate and is rotatably connected to the support frame. A first motor is installed at the input end of the screw. A guide rod is located in front of the screw and is fixed to the support frame. A slider is slidably connected to the outer periphery of the guide rod and is threadedly connected to the screw. A rotating block is rotatably connected to the rear end of the slider. A transmission wheel is fixed to the outer ring of the rotating block. A stop bar is located at the lower end of the transmission wheel and is fixed to the support frame. A first spring is fixed to the lower end of the rotating block. A weight is fixed to the lower end of the first spring. A semi-circular frame is fixed to the upper end of the slider. A top bar is rotatably connected to one end of the semi-circular frame. A second spring is fixed to the lower end of the top bar and is fixed to the lower end of the second spring.

[0009] Preferably, the upper end of the abutment and the outer ring of the drive wheel are both provided with a rubber layer, and the upper end of the abutment is in contact with the drive wheel.

[0010] Preferably, the outer ring of the weight block is provided with a rubber layer, and the upper end of the top strip is provided with a slope.

[0011] Preferably, a conveyor belt is installed at the bottom of the support frame, an injection pipe is fixed at one end of the support frame, and a hydraulic cylinder is installed on the inner wall of the other end of the support frame.

[0012] Preferably, the water guiding mechanism includes a guide plate, which is slidably connected inside the support frame and located below the filter plate. One end of the guide plate is provided with an insertion rod, which penetrates the wall of one end of the support frame and the guide plate.

[0013] Preferably, the deflector is inclined.

[0014] The advantages compared to existing technologies are as follows:

[0015] After the device filters the sludge, the first motor drives the screw to rotate forward, causing the slider to move towards the filter plate. During this process, the rotating block drives the weight at the lower end of the first spring to rotate. When the slider passes the first filter plate, the lower end of the filter plate will abut against the inclined surface at the upper end of the top bar due to the elasticity of the second spring. With the continuous movement of the slider, the top of the top bar will pass the first filter plate. Then, the first motor drives in reverse to reset the slider, thereby causing this filter plate to detach from the other filter plates. During the continuous movement of the slider, the rotating weight will strike one end of the filter plate, causing the dirt stuck to the filter plate to fall off. In this way, the filter cloth structure of the filter plate can be avoided from being damaged. Moreover, due to the elasticity of the first spring, the first spring and the weight will not affect the rotation of the rotating block, so that the weight can strike the filter plate multiple times, making the dirt removal effect better.

[0025] like Figures 1-4 As shown, a sludge depressurization treatment device includes a support frame 1, a plurality of filter plates 11 are slidably connected inside the support frame 1, a water guiding mechanism is installed below the filter plates 11, and a sludge discharge mechanism is also included.

[0026] A conveyor belt device 12 is installed at the bottom of the support frame 1. An injection pipe 13 is fixed at one end of the support frame 1, and a hydraulic cylinder 14 is installed on the inner wall of the other end of the support frame 1. The hydraulic cylinder 14 can be activated to squeeze multiple filter plates 11, and the conveyor belt device 12 can be activated to discharge the dislodged soil.

[0027] The water guiding mechanism includes a guide plate 2, which is slidably connected inside the support frame 1 and located below the filter plate 11. One end of the guide plate 2 is provided with an insertion rod 21, which penetrates the wall of one end of the support frame 1 and the guide plate 2. The guide plate 2 is inclined. By tilting the guide plate 2, the water filtered by the pressure filter can flow out of the device along the tilt of the guide plate 2.

[0028] The sludge removal mechanism includes a screw 3, which is positioned in front of the filter plate 11 and rotatably connected to the support frame 1. A first motor 31 is installed at the input end of the screw 3. A guide rod 32 is positioned in front of the screw 3 and is fixed to the support frame 1. A slider 33 is slidably connected to the outer periphery of the guide rod 32 and is threadedly connected to the screw 3. A rotating block 34 is rotatably connected to the rear end of the slider 33. A transmission wheel 35 is fixed to the outer ring of the rotating block 34. A stop bar 36 is positioned at the lower end of the transmission wheel 35 and is fixed to the support frame 1. A rubber layer is provided on the upper end of the stop bar 36 and the outer ring of the transmission wheel 35. The upper end of the 6 is in contact with the transmission wheel 35. The lower end of the rotating block 34 is fixed with a first spring 37. The lower end of the first spring 37 is fixed with a drop block 38. The outer ring of the drop block 38 is provided with a rubber layer. The upper end of the top bar 310 is provided with an inclined surface. The upper end of the slider 33 is fixed with a semi-circular frame 39. One end of the semi-circular frame 39 is rotatably connected to the top bar 310. The lower end of the top bar 310 is fixed with a second spring 311, and the lower end of the second spring 311 is fixed with the slider 33. Through the threaded connection between the slider 33 and the screw 3 and the sliding connection between the slider 33 and the guide rod 32, the slider 33 can move when the first motor 31 drives the screw 3 to rotate.

[0029] Working principle: During operation, the sludge pump is first connected to the input end of the injection pipe 13, and then sludge is injected into the filter plates 11. After injection, the hydraulic cylinder 14 is activated to squeeze the multiple filter plates 11, thereby squeezing out the water from the sludge. The filtered water flows out of the device along the inclined guide plate 2. After filtration is completed, the insertion rod 21 is pulled out, so that the guide plate 2 is not limited. Then the guide plate 2 is pulled out of the device. After the preparation is completed, the first motor 31 is started. Through the threaded connection between the screw 3 and the slider 33 and the sliding connection between the slider 33 and the guide rod 32, when the first motor 31 drives the screw 3 to rotate forward, it can move the slider 33 towards the filter plate 11. During this process, through the contact between the transmission wheel 35 and the abutment 36, when the slider 33 moves, it can drive the rotating block 34 to drive the first The weight 38 at the lower end of the spring 37 rotates. When the slider 33 passes the first filter plate 11, the lower end of the filter plate 11 will abut against the inclined surface of the upper end of the top bar 310 due to the elasticity of the second spring 311. As the slider 33 continues to move, the top end of the top bar 310 will pass the first filter plate 11. Then the first motor 31 drives in the opposite direction to reset the slider 33, thereby causing this filter plate 11 to detach from the other filter plates 11. During the continuous movement of the slider 33, the rotating weight 38 will strike one end of the filter plate 11, and the soil stuck to the filter plate 11 will fall off. Due to the elasticity of the first spring 37, the first spring 37 will bend after the weight 38 strikes the filter plate 11 once, so that the rotating block 34 can continue to rotate, allowing the weight 38 to strike the filter plate 11 multiple times, thereby improving the soil removal effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
