Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment equipment, in particular to a sewage treatment device for density board processing. Background Art

[0002] In order to improve the utilization rate of wood, wood is usually processed into density boards, and then the density boards are used to process furniture. The specific process of processing density boards is: crush the wood into granular wood powder of a certain size, then, fully mix the wood powder and adhesive to obtain a mixture, and then use hydraulic equipment to compress the mixture into a density board blank, and finally cut the density board blank into a density board of preset size according to the preset size. However, during the pressing process of the density board, the moisture contained in the wood powder will be squeezed out. These wood powders contain excess adhesive and organic matter in the wood powder. If these wastewaters are directly discharged into the environment, the water bodies in the environment will be eutrophicated. Therefore, the density board processing wastewater needs to be treated before discharge.

[0003] When treating the wastewater from density board processing, the filter press can be used to remove solid impurities such as wood powder and adhesive glue in the wastewater under the action of pressure. However, the filter cake formed after pressurization sometimes sticks between the filter plates and will not fall off with gravity. Manual shoveling is not only time-consuming and labor-intensive, but also inefficient. In response to the above problems, the following solutions are proposed. Summary of the invention

[0006] Preferably, the cleaning mechanism also includes a protruding block slidably connected to the inner wall of the shell bracket, a sliding block 2 is slidably connected to the inner wall of the shell bracket, a telescopic spring 1 is fixedly connected to the outer wall of the sliding block 2, a hydraulic box is fixedly connected to the inner wall of the shell bracket, a hydraulic plate is slidably connected to the inner wall of the hydraulic box, and a telescopic plate is slidably connected to the inner wall of the hydraulic box. The characteristic of the pressure plate pushing the filter plate to move is utilized, and an electric hydraulic rod is provided. After the filtration is completed, filter cakes will be formed between the filter plates and the filter plates. At this time, the electric hydraulic rod is energized to drive the pressure plate to contract. When the pressure plate retracts, all the filter plates are driven to move through the connecting rods 1 and 2, so that the filter plates are separated from each other. At this time, a part of the filter cakes will fall downward with gravity, and a part of the stickier filter cakes will still adhere to the filter plate. However, when the pressure plate retracts, it will squeeze the air pressure telescopic rod 1, causing the air inside the air pressure telescopic rod 1 to rush in. When the filter plate is pressed against the filter element, the filter element is moved back and forth, and the filter element moves ...

[0007] Preferably, the cleaning mechanism also includes a piston rod slidably connected to the inner wall of the hydraulic plate, the outer wall of the piston rod is fixedly connected to the outer wall of the telescopic plate, the top of the filter plate is fixedly connected with a fixed block, the outer wall of the piston rod is slidably connected to the inner wall of the fixed block, the inner wall of the fixed block is slidably connected with a spring telescopic rod, the inner wall of the hydraulic box is fixedly connected with a hydraulic telescopic rod, and the inner wall of the hydraulic telescopic rod is slidably connected with a telescopic scraper. Utilizing the characteristics of the above-mentioned pressure plate pulling the filter plates away from each other, a hydraulic box is provided, and when the filter plates move away from each other instead of being squeezed by each other, the fixed blocks at both ends are driven away from each other, so that the piston rod slides outward, and when the piston rod slides outward, the telescopic plate at one end of the piston rod extends, and the telescopic plate on one side contracts. When the fixed blocks move away from each other, The spring telescopic rod is driven to extend outward, so that the hydraulic oil inside the fixed block enters the spring telescopic rod and drives the piston rod to move downward. When the piston rod moves downward, it drives the hydraulic plate to squeeze the hydraulic oil below it into the hydraulic telescopic rod, making it extend downward, and the hydraulic oil entering the hydraulic telescopic rod will push the telescopic scraper outward, making it extend outward and close to the outer surface of the filter plate. When the hydraulic telescopic rod moves downward, the telescopic scraper can scrape downward against the surface of the filter plate and can self-adjust according to the different concave and convex positions of the filter plate to scrape and clean the filter cake impurities on the filter plate that have strong adhesion but have not fallen off by vibration, so as to separate them from the surface of the filter plate, thereby avoiding long-term adhesion and extrusion that may damage the filter plate and reduce the filtering effect.

[0008] Preferably, the pressurized filtering mechanism also includes a rotating rod rotatably connected to the inner wall of the mixing box, the bottom of the rotating rod is fixedly connected to a fan blade, the top of the rotating rod is fixedly connected to a rotating plate, the outer wall of the rotating plate is rotatably connected to a connecting rod three, the inner wall of the pressure stop block is slidably connected to a push plate, the inner wall of the push plate is rotatably connected to the inner wall of the connecting rod three, after the sewage enters the mixing box, its greater pressure will push the fan blade to rotate, and when the fan blade rotates, it will drive the rotating rod and the rotating plate to rotate, and then the push plate is moved back and forth inside the pressure stop block through the connecting rod three to squeeze the gas inside the pressure stop block, thereby providing support for the operation of subsequent components.

[0009] Preferably, the pressurized filtering mechanism also includes a one-way valve fixedly connected to the inner wall of the push plate, an air inlet is opened on the inner wall of the filter plate, a filter cloth is fixedly connected to the outer wall of the filter plate, a water outlet is fixedly connected to the outer wall of the filter plate, a water outlet trough is fixedly connected to the outer wall of the outer shell bracket, and the outer wall of the water outlet trough is fixedly connected to the outer wall of the pressure stop block. Utilizing the characteristic that sewage enters the mixing box from the feed port through a water pump, before sewage is added, the filter plate will be squeezed, and a closed chamber will be formed between the filter plates, and the holes in the middle of the filter plate and the air inlets at the corners will form a connected state while being squeezed. Since the sewage is pressurized into the mixing box through the water pump, the pressure is relatively large, so that the sewage entering the mixing box can push the fan blades to rotate and drive the rotation The rod rotates, and when the rotating rod rotates, the push plate can be pushed and pulled by the rotating plate and the connecting rod three to move it back and forth. Since the one-way valve flows from the feed port to the filter plate in one direction, when the connecting rod three pulls the push plate, the external air will enter the inside of the pressure stop block, and when the connecting rod three pushes the push plate, the air inside the pressure stop block will enter the inside of the filter plate through the air inlet. Since the outer surface of the filter cloth will be filled with sewage impurities, its air permeability will become worse. After the air enters the filter plate, it will push the filter cloth outward to open it, so that the sewage impurities between the filter plates are further squeezed, and the water content of the filtered filter cake is reduced, thereby improving the filtration effect and filtration quality, and the flow rate of the filtered water can be promoted during gas pressurization, so that the filtration speed can also be increased.

[0010] Preferably, the crushing and discharging mechanism also includes a pneumatic telescopic rod 2 fixedly connected to the outer wall of the chain, the outer wall of the pneumatic telescopic rod 2 is fixedly connected to the outer wall of the pressure stop block, the top of the base is fixedly connected to a guide wheel rod, the inner wall of the chain is meshingly connected with a sprocket, the inner wall of the sprocket is rotatably connected with a bevel gear 1, and the inner wall of the bevel gear 1 is slidably connected with a convex tooth. When the pressure plate pulls the chain to move, the pneumatic telescopic rod 2 can make the chain close to the sprocket and the guide wheel rod, so that the chain and the sprocket are always in a meshing state to avoid derailment and restricting the operation of the equipment. Due to the design of the bevel teeth of the convex teeth, the sprocket can only drive the bevel gear 1 to rotate when it rotates in one direction, thereby ensuring the normal operation of subsequent components.

[0011] Preferably, the crushing and discharging mechanism also includes a telescopic spring two fixedly connected to the outer wall of the convex tooth, the outer wall of the bevel gear one is rotatably connected to the inner wall of the base, the outer wall of the bevel gear one is rotatably connected to the bevel gear two, the outer wall of the bevel gear two is rotatably connected to the inner wall of the base, the outer wall of the bevel gear two is fixedly connected to an auger, the outer wall of the auger is rotatably connected to the inner wall of the base, and a sprocket is provided by utilizing the characteristic that the pressure plate moves back and forth to drive the chain to move, and when the pressure plate squeezes the filter plate, the chain is pulled to move, and when the chain moves, the air pressure telescopic rod two is extended, so that the chain can be close to the guide wheel rod and the sprocket, and the sprocket rotates under the pulling of the chain, at this time, the inner concave part of the sprocket is relatively meshed with the convex tooth, and the sprocket drives the bevel gear one to rotate when rotating, and when the pressure plate pulls the filter plate to retract, the chain is acted upon by the air pressure telescopic rod two , continue to move closely with the guide wheel rod and the sprocket, but at this time the concave part of the sprocket no longer meshes with the convex teeth and turns to sliding. The convex teeth are squeezed and contracted, and the sprocket cannot drive the bevel gear one to rotate. When the bevel gear one rotates, the auger is driven to rotate by the bevel gear two, so that the fallen filter cake can slide down from the inner surface of the waste trough to the top of the auger, so that those large pieces of filter cake are stirred by the auger and broken into small pieces of filter cake and discharged outward, so as to realize the function of automatic collection of waste and discharging, so as to improve the working efficiency of the overall equipment, and also avoid the inconvenience of large pieces of filter cake filling up the waste trough in a short time and requiring frequent cleaning. In addition, the contact area of ​​the broken filter cake with the air is increased, so the little water remaining in it can be evaporated faster, and the smaller filter cake is more convenient for subsequent centralized collection and treatment.

[0012] The present invention has the following beneficial effects: (1) The present invention utilizes the characteristic of the pressure plate to push the filter plate to move, and sets an electric hydraulic rod. After the filtration is completed, filter cakes will be formed between the filter plates. At this time, the electric hydraulic rod is energized to run, driving the pressure plate to shrink. When the pressure plate shrinks, it drives all the filter plates to move through the connecting rods 1 and 2, so that the filter plates are separated from each other. At this time, part of the filter cake will fall downward due to gravity, and part of the stickier filter cake will still adhere to the filter plate. However, when the pressure plate shrinks, it squeezes the pneumatic telescopic rod 1, so that the air inside the pneumatic telescopic rod 1 flows into the inside of the shell bracket, thereby forcing the protruding block to extend outward. When the protruding block extends, it pushes the sliding block 2 to shrink tightly against the outer surface of the protruding block. After extending outward, when the filter plate moves, the contact between the rotating wheel and the protruding block causes the filter plate to vibrate up and down, so that those impurities with strong adhesion can be vibrated and fall off, to avoid impurities sticking to the filter plate and affecting the filtering effect of sewage, or the inconvenience of manual cleaning later. When the pressure plate pushes and squeezes the filter plate, due to the extension of the air pressure telescopic rod 1, the gas inside the shell bracket refluxes, allowing the protruding block to retract downward, and under the action of the telescopic spring 1, the sliding blocks 2 at both ends are pressed against each other to form a closure, so that the filter plate does not vibrate up and down when being squeezed, thereby avoiding misalignment between the filter plates and making it impossible to form a closed chamber between the filter plates, affecting the filtering effect and quality of the equipment.

[0013] (2) The present invention utilizes the characteristic that the pressure plate pulls the filter plates away from each other and sets a hydraulic box. When the filter plates move away from each other instead of being squeezed, the fixed blocks at both ends are driven to move away from each other, thereby causing the piston rod to slide outward. When the piston rod slides outward, the telescopic plate at one end of the piston rod extends and the telescopic plate at the other end contracts. When the fixed blocks move away from each other, the spring telescopic rod is driven to extend outward, thereby causing the hydraulic oil inside the fixed block to enter the spring telescopic rod and drive the piston rod to move downward. When the piston rod moves downward, the hydraulic plate is driven to squeeze the hydraulic oil below it. The oil enters the hydraulic telescopic rod, making it extend downward, and the hydraulic oil entering the hydraulic telescopic rod will push the telescopic scraper outward, making it extend outward and close to the outer surface of the filter plate, so that when the hydraulic telescopic rod moves downward, the telescopic scraper can scrape downward close to the surface of the filter plate, and can self-adjust according to the different concave and convex positions of the filter plate, so as to scrape and clean the filter cake impurities on the filter plate that have strong adhesion and have not fallen off by vibration, so as to separate them from the surface of the filter plate, thereby avoiding long-term adhesion and extrusion that may damage the filter plate and reduce the filtering effect.

[0014] (3) The present invention utilizes the characteristic that sewage enters the mixing box from the feed port through a water pump. Before sewage is added, the filter plate will be squeezed, and a closed chamber will be formed between the filter plates. The holes in the middle of the filter plate and the air inlets at the corners will form a connected state while being squeezed. Since the sewage is pressurized into the mixing box by the water pump, the pressure is relatively high, so that the sewage entering the mixing box can drive the fan blades to rotate and drive the rotating rod to rotate. When the rotating rod rotates, the push plate can be pushed and pulled by the rotating plate and the connecting rod to move back and forth. Since the one-way valve is from the feed port to the filter plate, the one-way valve is connected to the filter plate. One-way circulation, when connecting rod three pulls the push plate, external air will enter the inside of the pressure stop block, and when connecting rod three pushes the push plate, the air inside the pressure stop block will enter the inside of the filter plate through the air inlet. Since the outer surface of the filter cloth will be filled with sewage impurities, its air permeability will become worse. After the air enters the filter plate, it will push the filter cloth outward to open it, so that the sewage impurities between the filter plates are further squeezed, and the water content of the filtered filter cake is reduced, thereby improving the filtration effect and filtration quality, and the flow rate of the filtered water can be promoted during gas pressurization, so that the filtration speed can also be increased.

[0015] (4) The present invention utilizes the characteristic that the pressure plate moves back and forth to drive the chain to move, and sets a sprocket. When the pressure plate squeezes the filter plate, the chain is pulled to move. When the chain moves, it drives the air pressure telescopic rod 2 to extend, so that the chain can be close to the guide wheel rod and the sprocket. The sprocket rotates under the pull of the chain. At this time, the concave part of the sprocket is relatively meshed with the convex tooth. When the sprocket rotates, it drives the bevel gear 1 to rotate. When the pressure plate pulls the filter plate to retract, the chain is affected by the air pressure telescopic rod 2 and continues to move closely with the guide wheel rod and the sprocket. However, at this time, the concave part of the sprocket is no longer meshed with the convex tooth, and it turns to slide. The convex tooth is squeezed and shrinks, and the sprocket cannot drive the bevel gear 1 to rotate. When the bevel gear 1 rotates, the bevel gear 2 drives the auger to rotate, so that the fallen filter cake can slide down from the inner surface of the waste trough to the top of the auger, so that the large pieces of filter cake are stirred by the auger and broken into small pieces of filter cake and discharged outward, so as to realize the function of automatic collection of waste and discharge, so as to improve the working efficiency of the overall equipment, and also avoid the inconvenience of large pieces of filter cake filling up the waste trough in a short time and requiring frequent cleaning. In addition, the contact area of ​​the broken filter cake with the air is increased, so the little water remaining in it can evaporate faster, and the smaller filter cake is more convenient for subsequent centralized collection and treatment.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] For example, see Figure 1-Figure 5 The present invention is a density board processing wastewater treatment device, comprising a cleaning mechanism 1, the cleaning mechanism 1 also comprises a shell bracket 101, the inner wall of the shell bracket 101 is fixedly connected with an electric hydraulic rod 102, the outer wall of the electric hydraulic rod 102 is fixedly connected with a pressing plate 103, and the outer wall of the pressing plate 103 is rotatably connected with a connecting rod 104; The pressure filtering mechanism 2 includes a pressure stop block 201 fixedly connected to the inner wall of the housing support 101, a stirring box 202 is fixedly connected to the outer wall of the pressure stop block 201, and a feed port 203 is opened on the inner wall of the stirring box 202; The crushing and discharging mechanism 3 comprises a base 301 fixedly connected to the bottom of the outer shell bracket 101 , a waste trough 302 is fixedly connected to the top of the base 301 , and a chain 303 is fixedly connected to the outer wall of the pressing plate 103 .

[0021] The cleaning mechanism 1 also includes a filter plate 105 rotatably connected to the inner wall of the connecting rod 104, a connecting rod 106 is rotatably connected to the outer wall of the filter plate 105, a sliding block 107 is rotatably connected to the inner wall of the connecting rod 106, the outer wall of the sliding block 107 is slidably connected to the outer wall of the housing bracket 101, a rotating wheel 108 is rotatably connected to the inner wall of the sliding block 107, and a pneumatic telescopic rod 109 is fixedly connected to the outer wall of the pressure plate 103, and the outer wall of the pneumatic telescopic rod 109 is fixedly connected to the outer wall of the pressure plate 103. It is fixedly connected to the outer wall of the shell bracket 101, and the connecting rod 104 and the connecting rod 2 106 can make the pressure plate 103 drive all the filter plates 105 to move when moving, so that when the pressure plate 103 moves to the maximum value, the filter plates 105 and the filter plates 105 will be fully opened to improve work efficiency and avoid the cumbersome process of the plate pulling trolley pulling the filter plate 105. When the pressure plate 103 moves, it will drive the pneumatic telescopic rod 109 to extend and retract, so as to improve the power support later.

[0022] The cleaning mechanism 1 also includes a protruding block 110 slidably connected to the inner wall of the outer shell bracket 101, a sliding block 111 is slidably connected to the inner wall of the outer shell bracket 101, a telescopic spring 112 is fixedly connected to the outer wall of the sliding block 111, a hydraulic box 113 is fixedly connected to the inner wall of the outer shell bracket 101, a hydraulic plate 114 is slidably connected to the inner wall of the hydraulic box 113, and a telescopic plate 115 is slidably connected to the inner wall of the hydraulic box 113. The characteristic of the pressure plate 103 pushing the filter plate 105 to move is utilized, and an electric hydraulic rod 102 is set. After the filtration is completed, filter cakes will be formed between the filter plates 105. At this time, the electric hydraulic rod 102 is powered on to drive the pressing plate 103 to shrink. When the pressing plate 103 shrinks, it drives all the filter plates 105 to move through the connecting rod 104 and the connecting rod 2 106, so that the filter plates 105 are separated from each other. At this time, part of the filter cake will fall downward with gravity, and part of the sticky filter cake will still adhere to the filter plate 105. However, when the pressing plate 103 shrinks, it will squeeze the pneumatic telescopic rod 109, so that the inside of the pneumatic telescopic rod 109 is The air from the outside flows into the inside of the housing bracket 101, thereby forcing the protruding block 110 to extend outward. When the protruding block 110 extends outward, the sliding block 111 is pushed to shrink close to the outer surface of the protruding block 110. Since the protruding block 110 extends outward, the filter plate 105 vibrates up and down when it moves through the contact between the rotating wheel 108 and the protruding block 110, so that those impurities with strong adhesion can be vibrated and fall off, thereby preventing the impurities from sticking to the filter plate 105 and affecting the filtering effect of the sewage, or the inconvenience of manual cleaning in the later stage. When the pressure plate 103 pushes and squeezes the filter plate 105, due to the extension of the gas pressure telescopic rod 109, the gas inside the shell bracket 101 flows back, causing the protruding block 110 to retract downward, and the sliding block 111 at both ends is pressed against each other under the action of the telescopic spring 112, forming a closed state, so that the filter plate 105 does not vibrate up and down when being squeezed, thereby avoiding the mutual misalignment between the filter plates 105 and the filter plates 105, so that the closed chamber between the filter plates 105 and the filter plates 105 cannot be formed, affecting the filtering effect and filtering quality of the equipment.

[0023] The cleaning mechanism 1 also includes a piston rod 116 slidably connected to the inner wall of the hydraulic plate 114, the outer wall of the piston rod 116 is fixedly connected to the outer wall of the telescopic plate 115, the top of the filter plate 105 is fixedly connected with a fixed block 117, the outer wall of the piston rod 116 is slidably connected to the inner wall of the fixed block 117, the inner wall of the fixed block 117 is slidably connected with a spring telescopic rod 118, the inner wall of the hydraulic box 113 is fixedly connected with a hydraulic telescopic rod 119, and the inner wall of the hydraulic telescopic rod 119 is slidably connected with a telescopic scraper 120. The characteristic of the above-mentioned pressing plate 103 pulling the filter plates 105 away from each other is utilized to set a hydraulic box 113. When the filter plates 105 move away from each other by being squeezed by each other, the fixed blocks 117 at both ends are driven away from each other, so that the piston rod 116 slides outward. When the piston rod 116 slides outward, the telescopic plate 115 at one end of the piston rod 116 extends, and the telescopic plate 115 on one side contracts. When the fixed blocks 117 move away from each other, the spring telescopic rod 118 is driven to extend outward, so that the hydraulic oil inside the fixed block 117 enters the spring telescopic rod 118 and drives the piston rod 116 to move downward. When the piston rod 116 moves downward, it drives the hydraulic plate 114 to squeeze the hydraulic oil below it into the hydraulic telescopic rod 119, making it extend downward, and the hydraulic oil entering the hydraulic telescopic rod 119 will push the telescopic scraper 120 outward, so that it extends outward and close to the outer surface of the filter plate 105, so that when the hydraulic telescopic rod 119 moves downward, the telescopic scraper 120 can scrape downward closely against the surface of the filter plate 105, and can self-adjust according to the different concave and convex positions of the filter plate 105, so that those filter cake impurities on the filter plate 105 that have strong adhesion but are not vibrated and fall off are scraped and cleaned, so that they are separated from the surface of the filter plate 105, so as to avoid long-term adhesion and extrusion that damages the filter plate 105 and reduces the filtering effect.

After the sewage enters the mixing box 202, its greater pressure will push the fan blade 205 to rotate, and when the fan blade 205 rotates, it will drive the rotating rod 204 and the rotating plate 206 to rotate, and then the push plate 208 is moved back and forth inside the pressure stop block 201 through the connecting rod three 207 to squeeze the gas inside the pressure stop block 201, providing support for the operation of subsequent components.

[0025] The pressurized filtering mechanism 2 also includes a one-way valve 209 fixedly connected to the inner wall of the push plate 208, an air inlet 210 is opened on the inner wall of the filter plate 105, a filter cloth 211 is fixedly connected to the outer wall of the filter plate 105, a water outlet 212 is fixedly connected to the outer wall of the filter plate 105, a water outlet 213 is fixedly connected to the outer wall of the housing bracket 101, and the outer wall of the water outlet 213 is fixedly connected to the outer wall of the pressure stop block 201, and the sewage is pumped from the feed port 201 through the water pump. 3 enters the mixing box 202. Before the sewage is added, the filter plate 105 will be squeezed, and a closed chamber will be formed between the filter plates 105 and the filter plates 105. The holes in the middle of the filter plate 105 and the air inlet 210 at the corners will form a connected state while being squeezed. Since the sewage is pressurized into the mixing box 202 by the water pump, the pressure is relatively high, so that the sewage entering the mixing box 202 can push the fan blades 205 to rotate and drive the rotation The rod 204 rotates. When the rotating rod 204 rotates, the push plate 208 can be pushed and pulled by the rotating plate 206 and the connecting rod 3 207 to move it back and forth. Since the one-way valve 209 is a one-way flow from the feed port 203 to the filter plate 105, when the connecting rod 3 207 pulls the push plate 208, the external air will enter the inside of the pressure stop block 201. When the connecting rod 3 207 pushes the push plate 208, the air inside the pressure stop block 201 will pass through the air inlet 210. After entering the interior of the filter plate 105, the outer surface of the filter cloth 211 will be filled with sewage impurities, and its air permeability will become poor. After the air enters the filter plate 105, it will push the filter cloth 211 outward to expand it, so that the sewage impurities between the filter plates 105 are further squeezed, and the water content of the filtered filter cake is reduced, thereby improving the filtering effect and filtering quality, and the flow rate of the filtered water can be promoted during the gas pressurization, so that the filtering speed can also be increased.

[0026] The crushing and discharging mechanism 3 also includes a pneumatic telescopic rod 204 fixedly connected to the outer wall of the chain 303, the outer wall of the pneumatic telescopic rod 204 is fixedly connected to the outer wall of the pressure stop block 201, the top of the base 301 is fixedly connected to a guide wheel rod 305, the inner wall of the chain 303 is meshed with a sprocket 306, the inner wall of the sprocket 306 is rotatably connected to a bevel gear 1 307, and the inner wall of the bevel gear 1 307 is slidably connected to a convex tooth 308. When the pressure plate 103 pulls the chain 303 to move, the pneumatic telescopic rod 204 can make the chain 303 close to the sprocket 306 and the guide wheel rod 305, so that the chain 303 and the sprocket 306 are always in a meshing state to avoid derailment and restricting the operation of the equipment. Due to the design of the bevel teeth of the convex tooth 308, the sprocket 306 can only drive the bevel gear 1 307 to rotate when it rotates in one direction, thereby ensuring the normal operation of subsequent components.

[0027] The crushing and discharging mechanism 3 also includes a telescopic spring 2 309 fixedly connected to the outer wall of the convex tooth 308, the outer wall of the bevel gear 1 307 is rotatably connected to the inner wall of the base 301, the outer wall of the bevel gear 1 307 is rotatably connected to the bevel gear 2 310, the outer wall of the bevel gear 2 310 is rotatably connected to the inner wall of the base 301, the outer wall of the bevel gear 2 310 is fixedly connected to the outer wall of the bevel gear 2 310, the outer wall of the auger 311 is rotatably connected to the inner wall of the base 301, and the pressure plate 103 is used to move back and forth. The movement drives the chain 303 to move, and a sprocket 306 is set. When the pressure plate 103 squeezes the filter plate 105, the chain 303 is pulled to move. When the chain 303 moves, the air pressure telescopic rod 2 304 is extended, so that the chain 303 can be close to the guide wheel rod 305 and the sprocket 306. The sprocket 306 rotates under the pull of the chain 303. At this time, the concave part of the sprocket 306 is relatively meshed with the convex tooth 308. When the sprocket 306 rotates, it drives the bevel gear 1 307 to rotate. When the pressure plate 103 pulls When the filter plate 105 retracts, the chain 303 is acted upon by the air pressure telescopic rod 2 304, and continues to move closely with the guide wheel rod 305 and the sprocket 306. However, at this time, the inner concave part of the sprocket 306 is no longer meshed with the convex tooth 308, and turns to slide. The convex tooth 308 is squeezed and contracts, and the sprocket 306 cannot drive the bevel gear 1 307 to rotate. When the bevel gear 1 307 rotates, the auger 311 is driven to rotate through the bevel gear 2 310, so that the fallen filter cake can slide down from the inner surface of the waste tank 302 to the The auger 311 is used to stir and crush the large pieces of filter cake into small pieces, which are then discharged to the outside, so as to realize the function of automatically collecting waste and discharging the materials, so as to improve the working efficiency of the whole equipment, and to avoid the inconvenience of frequent cleaning caused by large pieces of filter cake that fill up the waste tank 302 in a short time. In addition, the contact area of ​​the broken filter cake with the air is increased, so the small amount of water remaining in the broken filter cake can be evaporated faster, and the smaller filter cake is more convenient for the subsequent centralized collection and treatment.

[0028] A specific application of this embodiment is: before using the device, first install the device at the required position, then connect the sewage pipe to the feed port 203, and turn on the power of the electric hydraulic rod 102. After the filtration is completed, filter cakes will be formed between the filter plates 105 and the filter plates 105. At this time, the electric hydraulic rod 102 is powered on to drive the pressing plate 103 to shrink. When the pressing plate 103 retracts, it drives all the filter plates 105 to move through the connecting rod 104 and the connecting rod 206, so that the filter plates 105 are separated from each other. At this time, a part of the filter cake will fall downward with gravity, and a part of the stickier filter cake will still adhere to the filter plate 105. However, when the pressing plate 103 retracts, it will squeeze the pneumatic telescopic rod 109, so that the pneumatic telescopic rod 109 is pressed against the filter plate 105. 9, the air inside the housing support 101 rushes into the housing support 101, thereby forcing the protruding block 110 to extend outward. When the protruding block 110 extends outward, the sliding block 111 is pushed to shrink against the outer surface of the protruding block 110. After the protruding block 110 extends outward, the filter plate 105 is moved, and the contact between the rotating wheel 108 and the protruding block 110 causes the filter plate 105 to vibrate up and down, so that those impurities with strong adhesion can be vibrated and fall off, thereby preventing the impurities from sticking to the filter plate 105 and affecting the filtering effect of the sewage, or the inconvenience of manual cleaning in the later stage. When the pressing plate 103 pushes and squeezes the filter plate 105, due to the extension of the air pressure telescopic rod 109, the gas inside the housing support 101 flows back, so that the protruding block 110 shrinks downward, and the sliding block 111 is pushed outward. Under the action of the telescopic spring 112, the sliding blocks 111 at both ends are pressed against each other to form a closure, so that the filter plate 105 will not vibrate up and down when being squeezed, thereby avoiding the mutual misalignment between the filter plates 105 and 105, so that the closed chamber between the filter plates 105 and 105 cannot be formed, which affects the filtering effect and quality of the equipment. A hydraulic box 113 is set. When the filter plates 105 are squeezed and moved away from each other, the fixed blocks 117 at both ends are driven to move away from each other, so that the piston rod 116 slides outward. When the piston rod 116 slides outward, the telescopic plate 115 at one end of the piston rod 116 extends, and the telescopic plate 115 on one side contracts. When the fixed blocks 117 move away from each other, the spring telescopic rod 118 is driven to extend outward. The hydraulic oil in the fixed block 117 enters the spring telescopic rod 118 and drives the piston rod 116 to move downward. When the piston rod 116 moves downward, it drives the hydraulic plate 114 to squeeze the hydraulic oil below it into the hydraulic telescopic rod 119, making it extend downward. The hydraulic oil entering the hydraulic telescopic rod 119 will push the telescopic scraper 120 outward, making it extend outward and close to the outer surface of the filter plate 105. When the hydraulic telescopic rod 119 moves downward, the telescopic scraper 120 can scrape downward closely against the surface of the filter plate 105, and can self-adjust according to the different concave and convex positions of the filter plate 105, so that the filter cake impurities on the filter plate 105 that have strong adhesion and have not been vibrated and fallen off can be scraped and cleaned, so that they are separated from the surface of the filter plate 105.Avoid long-term attachment and extrusion that may damage the filter plate 105 and reduce the filtering effect.

[0029] Taking advantage of the fact that sewage enters the mixing box 202 from the feed port 203 through the water pump, before sewage is added, the filter plate 105 will be squeezed, and a closed chamber will be formed between the filter plates 105 and 105, and the holes in the middle of the filter plate 105 and the air inlet 210 at the corners will form a connected state while being squeezed. Since the sewage is pressurized into the mixing box 202 through the water pump, the pressure is relatively large, so that the sewage entering the mixing box 202 can push the fan blade 205 to rotate and drive the rotating rod 204 to rotate. When the rotating rod 204 rotates, the push plate 208 can be pushed and pulled by the rotating plate 206 and the connecting rod 207 to move back and forth. Since the one-way valve 209 is from the feed port 203 to the The filter plate 105 has one-way circulation. When the connecting rod three 207 pulls the push plate 208, the external air will enter the inside of the pressure stop block 201. When the connecting rod three 207 pushes the push plate 208, the air inside the pressure stop block 201 will enter the inside of the filter plate 105 through the air inlet 210. Since the outer surface of the filter cloth 211 will be filled with sewage impurities, its air permeability will become poor. After the air enters the filter plate 105, it will push the filter cloth 211 outward to expand it, so that the sewage impurities between the filter plates 105 and 105 are further squeezed, and the water content of the filtered filter cake is reduced, thereby improving the filtering effect and the quality of the filtering. In addition, the flow rate of the filtered water can be promoted during the gas pressurization, so that the filtering speed can also be increased.

[0030] Utilizing the characteristic that the pressing plate 103 moves back and forth to drive the chain 303 to move, a sprocket 306 is provided. When the pressing plate 103 squeezes the filter plate 105, the chain 303 is pulled to move. When the chain 303 moves, the gas pressure telescopic rod 2 304 is extended, so that the chain 303 can be close to the guide wheel rod 305 and the sprocket 306. The sprocket 306 rotates under the pulling of the chain 303. At this time, the concave part of the sprocket 306 is relatively meshed with the convex tooth 308. When the sprocket 306 rotates, it drives the bevel gear 1 307 to rotate. When the pressing plate 103 pulls the filter plate 105 to retract, the chain 303 is affected by the gas pressure telescopic rod 2 304 and continues to move closely with the guide wheel rod 305 and the sprocket 306. However, at this time, the concave part of the sprocket 306 is no longer meshed with the convex tooth 308, and it turns to slide. 8 is squeezed and contracted, and the sprocket 306 cannot drive the bevel gear 1 307 to rotate. When the bevel gear 1 307 rotates, the bevel gear 2 310 drives the auger 311 to rotate, so that the fallen filter cake can slide down from the inner surface of the waste tank 302 to the top of the auger 311, so that the large pieces of filter cake are stirred and broken into small pieces by the auger 311 and discharged outward, so as to realize the function of automatic waste collection and discharging, so as to improve the working efficiency of the whole equipment, and also avoid the large pieces of filter cake filling up the waste tank 302 in a short time, which requires frequent cleaning. In addition, the contact area of ​​the broken filter cake with the air is increased, so the little water remaining in it can evaporate faster, and the smaller filter cake is more convenient for subsequent centralized collection and treatment.
