Description

Technical Field

[0001] This invention relates to the field of sludge treatment technology, specifically to a fully automatic ultra-high pressure sludge filter press. Background Technology

[0002] Transportation costs are the main component of sludge treatment costs. Dewatering sludge can significantly reduce these costs. For example, dewatering sludge with a 95% moisture content to 50% reduces its weight by 90%, making sludge dewatering crucial. Current fully automatic ultra-high pressure sludge filter presses primarily rely on placing the sludge between two layers of filter cloth to squeeze out the water.

[0003] Chinese patent CN210728782U discloses a sludge filter press, including a support frame, a pre-cooling chamber located on the left side of the support frame, and a filter pressing mechanism installed on the right side of the pre-cooling chamber. A horizontal water pump is connected to the lower end of the pre-cooling chamber, which is connected to a wastewater treatment sedimentation tank. The outlet of the pre-cooling chamber is connected to the filter pressing mechanism. Multiple water outlet pipes are provided on the outer side of the filter cloth of the filter pressing mechanism, and a water collection tank is provided below the water outlet pipes. The lower part of the water collection tank is connected to the wastewater treatment tank via a pipe. This invention has a simple structure. By cooling, the solubility of sludge in water is reduced, improving the filter pressing efficiency. Simultaneously, the water collection tank allows for wastewater recycling, avoiding secondary pollution of the squeezed-out water.

[0004] However, the aforementioned sludge filter press cannot automatically discharge and compress the sludge into a column before discharge during the sludge pressing process. Manual intervention is required to handle and remove the sludge, which affects the continuous operation of the equipment, reduces processing efficiency, increases the workload of operators, and leads to increased maintenance and operating costs. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automatic ultra-high pressure sludge filter press to solve the problem mentioned in the background art that the sludge cake cannot be automatically discharged during the sludge pressing process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A fully automatic ultra-high pressure sludge filter press includes: a main beam, in which multiple sets of filter plates are slidably installed; a thrust plate and a mounting plate are fixedly installed at both ends of the main beam; a hydraulic rod is fixedly installed at one end of the mounting plate; the piston rod of the hydraulic rod passes through the mounting plate and a pressing plate is fixedly installed at its end; the pressing plate can press the multiple sets of filter plates together and press them against one end of the thrust plate by the push of the hydraulic rod, so that the multiple sets of filter plates can be connected to the feed inlet installed at one end of the thrust plate; and a water tap is connected to one end of each set of filter plates. Among them, the upper surfaces of multiple sets of filter plates, mounting plates and thrust plates are provided with guide grooves. A synchronization mechanism is slidably installed in the guide grooves. The synchronization mechanism enables multiple sets of filter plates to expand and contract synchronously at equal intervals when pushed and pulled. The synchronizing mechanism is slidably installed with a purging mechanism. The blowing end of the purging mechanism slides through the synchronizing mechanism and is located between two sets of trapezoidal grooves. The trapezoidal grooves are opened on the upper surface of each set of filter plates so that when the filter plates are synchronously stretched out to the same equidistant distance, the blowing end of the purging mechanism can penetrate the sludge cake through the gap between them. A V-shaped cylinder is fixedly installed on the lower surface of the main beam. A sludge solidification mechanism is rotatably installed inside the V-shaped cylinder. The V-shaped cylinder is located at the lower end of multiple filter plates and can receive the sludge blown down by the purging mechanism and compact and discharge it.

[0007] Preferably, the sludge solidification mechanism includes a geared motor, which is fixedly installed at one end of the V-shaped cylinder. The output shaft of the geared motor passes through the V-shaped cylinder and is fixedly installed with a spiral conveying rod. The spiral conveying rod is rotatably installed at the bottom of the V-shaped cylinder and can push the sludge into the compaction cylinder. The compaction cylinder is rotatably installed at one end of the main beam and can be rotated 90° to connect with the V-shaped cylinder. The lower half of the outer surface of the compaction cylinder is provided with drainage holes.

[0008] Preferably, the outer surfaces of the compaction cylinder are rotatably connected to the piston rod of the first electric push rod, which is rotatably mounted on the inner side of the support leg of the main beam. This allows the first electric push rod to push and pull the compaction cylinder to rotate 90° at one end of the main beam, thereby connecting the compaction cylinder with the V-shaped cylinder to allow the mud to be pushed in and rotated to allow the compacted mud to be poured out as a column.

[0009] Preferably, the purging mechanism includes an air pump, which is fixedly installed at one end of a support plate, and the support plate is fixedly installed at one end of a clamping plate. One end of the air pump's air inlet is connected to a flexible hose, and the other end of the flexible hose is connected to a rigid pipe. The other end of the rigid pipe is connected to a trapezoidal nozzle, which allows the trapezoidal nozzle to blow compressed gas at a 45° angle to both sides and downwards.

[0010] Preferably, the rigid tube slides out from the synchronization mechanism and drives the trapezoidal air nozzle to be positioned between the two trapezoidal grooves of the two sets of filter plates.

[0011] Preferably, a sliding block is fixedly installed on the outer surface of the upper end of the rigid tube. Both sides of the sliding block slide out from the inner sides of the first U-shaped frame and the second U-shaped frame. The first U-shaped frame slides inside the second U-shaped frame. The first U-shaped frame and the second U-shaped frame are both fixedly installed on the upper surface of the piston rod of the two sets of second electric push rods. The two sets of second electric push rods are respectively fixedly installed on the inner upper surface of the mounting plate and the thrust plate. Specifically, the first U-shaped frame and the second U-shaped frame can be supported by the piston rods of the two sets of second electric push rods. When the support plate drives one of the sets of second electric push rods to pull, one of the sets of second electric push rods can pull the first U-shaped frame out of the second U-shaped frame and extend it.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the design of filter plates, hydraulic rods, pressing plates, thrust plates, V-shaped cylinders, synchronization mechanisms, sludge solidification mechanisms, and purging mechanisms, sludge is filtered by pressure. The hydraulic rods push the pressing plates, which in turn move the synchronization mechanism on the upper surface. This synchronization mechanism causes multiple sets of filter plates to synchronously and equidistantly reduce their spacing within the main beam until the pressing plates, filter plates, and thrust plates are completely pressed together. Assembly is then complete. Workers can then discharge sludge into the multiple sets of pressed filter plates through the feed inlet connected to one end of the thrust plate. As the sludge continuously enters the multiple sets of filter plates... The sludge is filtered through the filter plates, while the liquid separated from the sludge is discharged from a faucet connected to one end of the filter plates. Once the sludge is completely filtered, the hydraulic rod can be activated again to pull the pressure plate back. This retraction of the pressure plate activates the synchronization mechanism, which simultaneously unfolds multiple sets of filter plates. As the pressure plate is continuously pulled, the synchronization mechanism further widens the gap between the filter plates, ensuring that the spacing between each set is equal. This guarantees that the filter plates maintain synchronous and equidistant spacing during both pressing and unfolding, preventing uneven filtration caused by uneven spacing between the filter plates. This design addresses the issue of unevenness and facilitates the neat arrangement and operation of filter plates. During the simultaneous extension of multiple filter plates, the purging mechanism also moves to the space between each pair of filter plates. The purging mechanism then slides between each filter plate and blows high-pressure gas. The high-pressure gas is blown downwards at a 45° angle, effectively removing sludge from both sides of each filter plate and causing it to fall into the V-shaped cylinder. This high-pressure gas purging of sludge from both sides of the filter plates achieves automated cleaning, improving the equipment's continuous operation and cleaning efficiency. It also eliminates the need for manual intervention to handle and remove sludge cakes and reduces... The system reduces maintenance and operating costs. After the sludge is blown into the V-shaped cylinder, the sludge solidification mechanism is activated. This mechanism concentrates and compresses the sludge into a cylindrical shape, which is then automatically discharged to the outside. Concentrating and compressing the sludge into a cylindrical shape facilitates its storage, transportation, and subsequent utilization or treatment, reducing volume and improving processing efficiency. Through the coordinated work of these components, the entire filter press system achieves a highly efficient, automated, and clean sludge treatment process, improving filtration efficiency, reducing the need for manual operation, and minimizing environmental pollution.

[0013] 2. Through the design of the geared motor, screw conveyor, first electric push rod, and compaction cylinder, the geared motor can be activated after the sludge is blown into the V-shaped cylinder by the blowing mechanism. The geared motor will drive the screw conveyor to rotate inside the V-shaped cylinder, pushing the sewage continuously. This continuous pushing of sludge into the compaction cylinder, which is connected to the V-shaped cylinder, will compact the sludge into a cylindrical shape identical to the compaction cylinder. During the compression process, the liquid contained in the sludge can be discharged again through the drainage holes opened at the lower end of the outer surface of the compaction cylinder. When it is necessary to discharge the compacted cylindrical sludge, the first electric push rod can be activated. The piston rod of the push rod pushes the compaction cylinder to flip at one end of the main beam. As the first electric push rod continues to push, the compaction cylinder can be pushed and flipped 90°, so that the sludge inlet of the compaction cylinder faces downward and the cylindrical sludge stored inside is poured out, thus compacting the sludge into a cylindrical shape. This process can significantly reduce the volume of sludge, improve processing efficiency, and ensure the consistency and stability of the sludge column volume. Furthermore, the automatic discharge of the sludge column reduces the residence time of sludge in the equipment, which helps to keep the equipment clean. The cleaning and maintenance process is also made simpler, which is conducive to the long-term stable operation of the equipment.

[0014] 3. Through the design of the air pump, hose, rigid pipe, sliding block, second electric push rod, second U-shaped frame, first U-shaped frame, and trapezoidal air nozzle, when multiple sets of filter plates are pulled out at equal intervals by the synchronous mechanism, the synchronous mechanism will also pull the rigid pipe to keep it between every two sets of filter plates. At the same time, the rigid pipe will slide within the first and second U-shaped frames through the sliding block. The spacing of the rigid pipes will be fully extended through the hose. When the filter plates are extended and the internal sludge needs to be cleaned, the two sets of second electric push rods can be activated. The two sets of second electric push rods can pull the first and second U-shaped frames vertically downward through the piston rod. This allows the first and second U-shaped frames to drive the internally sliding sliding block, which in turn drives the rigid pipe to slide downward within the synchronous mechanism and insert into every two sets of filter plates. The rigid tube allows the trapezoidal air nozzle at its lower end to slide between every two sets of filter plates. Then, the air pump can be activated to supply air to the hose, which in turn supplies compressed air into the rigid tube. This allows the rigid tube to blow high-pressure gas downwards at a 45° angle from the trapezoidal air nozzle. Subsequently, as the second electric push rod continues to pull down, the trapezoidal air nozzle blows air from top to bottom across one side of the filter plate, thoroughly removing the sludge inside. Compared to traditional manual cleaning, this method removes sludge from the filter plates faster and more thoroughly. Furthermore, the entire cleaning process is automated. With the control of the second electric push rod and the air pump, operators do not need to directly contact the sludge, thus reducing health risks and improving work efficiency.

[0015] 4. Through the design of the first connecting rod, the second connecting rod, the first rotating ring, the second rotating ring, the guide column, and the butterfly bolt, when multiple sets of filter plates are pulled out, the hydraulic rod can be activated to pull the clamping plate. The clamping plate can pull the first connecting rod and the second connecting rod to rotate and close in a scissor-like manner on the outer surface of the first rotating ring. The other ends of the first connecting rod and the second connecting rod will also close together. During the process of pulling the first connecting rod and the second connecting rod to close, they will drive the guide column to slide laterally in the guide groove. During the closing process, the first connecting rod and the second connecting rod will push the filter plates connected to them to be pulled by an equal distance. The connection of multiple sets of first connecting rods and second connecting rods realizes that pushing and pulling a set of clamping plates will drive multiple sets of filter plates to be pulled out synchronously and at equal distances. This ensures the smooth operation of the entire system and the consistency of the distance between the filter plates, which is conducive to maintaining the uniformity and efficiency of the filtration process. When the filter plates need to be removed, the operator can unscrew the wing bolts on the filter plates from the guide posts, thus releasing the restriction on the first and second connecting rods at the top of the filter plates. This allows the operator to slide and push the filter plates individually or move the first and second connecting rods to release the wing bolts, allowing the filter plates to avoid being covered by the top of the first and second connecting rods. This enables the operator to remove the filter plates from the main beam, allowing them to operate a single set of filter plates without affecting other parts of the system. This improves the system's flexibility and maintainability, and facilitates the inspection, cleaning, or replacement of individual filter plates. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-8 This embodiment provides the following technical solution: like Figures 1-3 As shown, a fully automatic ultra-high pressure sludge filter press includes: a main beam 1, with multiple sets of filter plates 106 slidably installed inside the main beam 1. A thrust plate 104 and a mounting plate 107 are fixedly installed at both ends of the main beam 1, respectively. A hydraulic rod 101 is fixedly installed at one end of the mounting plate 107. The piston rod of the hydraulic rod 101 passes through the mounting plate 107 and a pressing plate 102 is fixedly installed at its end. The pressing plate 102 can press the multiple sets of filter plates 106 together and press them against one end of the thrust plate 104 through the pushing of the hydraulic rod 101, so that the multiple sets of filter plates 106 can be connected to the feed inlet installed at one end of the thrust plate 104. A water tap is installed at one end of each set of filter plates 106. Among them, the upper surfaces of multiple filter plates 106, mounting plate 107 and thrust plate 104 are all provided with guide grooves 108. A synchronization mechanism 2 is slidably installed in the guide grooves 108. The synchronization mechanism 2 enables the multiple filter plates 106 to expand and contract synchronously at equal intervals when pushed and pulled. Among them, a purging mechanism 4 is slidably installed in the synchronization mechanism 2. The blowing end of the purging mechanism 4 slides through the synchronization mechanism 2 and is located between two sets of trapezoidal grooves 109. The trapezoidal grooves 109 are opened on the upper surface of each set of filter plates 106 so that when the filter plates 106 are synchronously stretched out at the same equidistant distance, the blowing end of the purging mechanism 4 can penetrate the gap between them to blow away the mud cake. Among them, a V-shaped cylinder 105 is fixedly installed on the lower surface of the main beam 1, and a mud solidification mechanism 3 is rotatably installed inside the V-shaped cylinder 105. The V-shaped cylinder 105 is located at the lower end of multiple filter plates 106, and can receive the mud blown down by the blowing mechanism 4 and compact and discharge it.

[0020] Through the design of filter plate 106, hydraulic rod 101, pressing plate 102, thrust plate 104, V-shaped cylinder 105, synchronization mechanism 2, sludge solidification mechanism 3, and purging mechanism 4, when filtering sludge, the pressing plate 102 can be pushed by activating the hydraulic rod 101. During the pushing process, the pressing plate 102 will drive the synchronization mechanism 2 on the upper surface to move together. The synchronization mechanism 2 will drive multiple sets of filter plates 106 to synchronously and equidistantly reduce their spacing within the main beam 1 until the pressing plate 102, filter plate 106, and thrust plate 104 are completely pushed together, thus completing the assembly. Then, the operator can discharge the sludge into the multiple sets of pressed filter plates 106 from the feed port installed at one end of the thrust plate 104. Within filter plates 106, sludge continuously enters and is filtered out. The liquid separated from the sludge is discharged from a faucet connected to one end of the filter plate 106. Once the sludge is completely filtered, the hydraulic rod 101 is activated again to pull back the clamping plate 102. During this retraction, the clamping plate 102 activates the synchronizing mechanism 2, which simultaneously extends the multiple filter plates 106. As the clamping plate 102 is continuously pulled, the synchronizing mechanism 2 further increases the spacing between the filter plates 106, ensuring that the spacing between each filter plate 106 is equal, thus guaranteeing that the multiple filter plates 106 function correctly during both clamping and extension. Maintaining synchronous and equidistant spacing avoids uneven filtration caused by uneven distances between filter plates 106, while also facilitating the neat arrangement and operation of the filter plates 106. During the process of the synchronization mechanism 2 extending multiple sets of filter plates 106, it also drives the blowing mechanism 4 to move between each pair of filter plates 106. Then, the blowing mechanism 4 can be activated to slide between each set of filter plates 106 and blow high-pressure gas. The high-pressure gas blown out is angled downwards at 45°, effectively blowing off the mud and sludge on both sides of each set of filter plates 106, causing it to fall into the V-shaped cylinder 105. By using high-pressure gas to blow off the mud and sludge on both sides of the filter plates 106, an automated cleaning function is achieved, improving the continuous operation capability and cleaning efficiency of the equipment. This eliminates the need for manual intervention in handling and removing sludge cakes, and reduces maintenance and operating costs. After the sludge is blown into the V-shaped cylinder 105, the sludge solidification mechanism 3 can be activated. The sludge solidification mechanism 3 can concentrate and push the sludge and compress it into a cylindrical shape. The compacted cylindrical sludge is automatically discharged to the outside by the sludge solidification mechanism 3. Concentrating and compressing the sludge into a cylindrical shape facilitates the storage, transportation, and subsequent utilization or treatment of the sludge, reduces volume, and improves processing efficiency. Through the coordinated work of these components, the entire filter press system achieves a highly efficient, automated, and clean sludge treatment process, which not only improves filtration efficiency but also reduces the need for manual operation and reduces environmental pollution.

[0021] like Figures 4-5As shown, the sludge solidification mechanism 3 includes a reduction motor 301, which is fixedly installed at one end of the V-shaped cylinder 105. The output shaft of the reduction motor 301 passes through the V-shaped cylinder 105 and a spiral conveying rod 302 is fixedly installed inside the V-shaped cylinder 105. The spiral conveying rod 302 is rotatably installed at the bottom of the V-shaped cylinder 105. The spiral conveying rod 302 can push the sludge into the compaction cylinder 304. The compaction cylinder 304 is rotatably installed at one end of the main beam 1 and can be rotated 90° to connect with the V-shaped cylinder 105. The lower half of the outer surface of the compaction cylinder 304 is provided with drainage holes.

[0022] The outer surfaces of the compaction cylinder 304 are rotatably connected to the piston rods of the first electric push rod 303. The first electric push rod 303 is rotatably installed on the inner side of the support leg of the main beam 1, so that the first electric push rod 303 can push and pull the compaction cylinder 304 to rotate 90° at one end of the main beam 1. This enables the compaction cylinder 304 to be connected to the V-shaped cylinder 105 so that the mud can be pushed in and rotated to allow the compacted mud column to be poured out.

[0023] Through the design of the geared motor 301, the screw conveyor 302, the first electric push rod 303, and the compaction cylinder 304, the geared motor 301 can be activated after the sludge is blown into the V-shaped cylinder 105 by the blowing mechanism 4. The geared motor 301 will drive the screw conveyor 302 to rotate and push the sewage in the V-shaped cylinder 105, continuously pushing the sludge into the compaction cylinder 304 connected to the V-shaped cylinder 105. The continuous pushing of sludge into the compaction cylinder 304 can compact the sludge into a cylindrical shape similar to that of the compaction cylinder 304. During the compression process, the liquid contained in the sludge can be discharged again from the drainage holes opened at the lower end of the outer surface of the compaction cylinder 304. When the sludge is discharged, the piston rod of the first electric push rod 303 can be activated to push the compaction cylinder 304 to flip at one end of the main beam 1. As the first electric push rod 303 continues to push, the compaction cylinder 304 can be pushed and flipped 90°, so that the sludge inlet of the compaction cylinder 304 faces downward and the cylindrical sludge stored inside is poured out, thus compacting the sludge into a cylindrical shape. This process can significantly reduce the volume of sludge, improve processing efficiency, and ensure the consistency and stability of the sludge column volume. Furthermore, the automatic discharge of the sludge column reduces the residence time of sludge in the equipment, which helps to keep the equipment clean. The cleaning and maintenance process is also made simpler, which is conducive to the long-term stable operation of the equipment.

[0024] like Figures 6-7As shown, the purging mechanism 4 includes an air pump 401, which is fixedly installed at one end of the support plate 103. The support plate 103 is fixedly installed at one end of the clamping plate 102. One end of the air port of the air pump 401 is connected to a flexible hose 402, and the other end of the flexible hose 402 is connected to a rigid pipe 403. The other end of the rigid pipe 403 is connected to a trapezoidal nozzle 408, which allows the trapezoidal nozzle 408 to blow the compressed gas at a 45° angle to the lower sides.

[0025] The rigid tube 403 slides out from the synchronization mechanism 2 and drives the trapezoidal air nozzle 408 to be located between the two trapezoidal grooves 109 of the two sets of filter plates 106.

[0026] A sliding block 404 is fixedly installed on the outer surface of the upper end of the rigid tube 403. Both sides of the sliding block 404 slide out from the inner sides of the first U-shaped frame 407 and the second U-shaped frame 406. The first U-shaped frame 407 slides inside the second U-shaped frame 406. The first U-shaped frame 407 and the second U-shaped frame 406 are both fixedly installed on the upper surface of the piston rods of the two sets of second electric push rods 405. The two sets of second electric push rods 405 are respectively fixedly installed on the inner upper surface of the mounting plate 107 and the thrust plate 104. Specifically, the first U-shaped frame 407 and the second U-shaped frame 406 can be supported by the piston rods of the two sets of second electric push rods 405. When the support plate 103 drives one of the sets of second electric push rods 405 to pull, one of the sets of second electric push rods 405 can pull the first U-shaped frame 407 out of the second U-shaped frame 406 and extend it.

[0027] The filter plate 106, which is pulled out by the synchronization mechanism 2, can be pulled down by two sets of second electric push rods 405 to move the first U-shaped frame 407 and the second U-shaped frame 406 vertically downward. This allows the first U-shaped frame 407 and the second U-shaped frame 406 to drive the rigid tube 403 to slide downward within the synchronization mechanism 2. This allows the rigid tube 403 to drive the trapezoidal air nozzle 408 at its lower end to slide between each pair of filter plates 106.

[0028] Through the design of the air pump 401, hose 402, rigid pipe 403, sliding block 404, second electric push rod 405, second U-shaped frame 406, first U-shaped frame 407, and trapezoidal air nozzle 408, when multiple sets of filter plates 106 are pulled out at equal intervals by the synchronization mechanism 2, the synchronization mechanism 2 will also pull the rigid pipe 403 to keep it between every two sets of filter plates 106. At the same time, the rigid pipe 403 will pass through the sliding block 404 to the first U-shaped frame 407 and the second U-shaped frame 408. The internal sliding mechanism 6, along with the increased spacing of the rigid tubes 403, is pulled out via the flexible hose 402. When the filter plate 106 is pulled out and internal sludge needs to be cleaned, two sets of second electric push rods 405 can be activated. These two sets of second electric push rods 405 can pull down the first U-shaped frame 407 and the second U-shaped frame 406 vertically via the piston rod, enabling the first U-shaped frame 407 and the second U-shaped frame 406 to drive the internally sliding block 404, which in turn drives the rigid tubes 403 synchronously. The mechanism 2 slides downwards between every two sets of filter plates 106, allowing the rigid tube 403 to drive the trapezoidal air nozzle 408 at its lower end to slide between every two sets of filter plates 106. Then, the air pump 401 can be activated to supply air to the hose 402, which in turn supplies compressed air into the rigid tube 403. This allows the rigid tube 403 to blow high-pressure gas out at a 45° angle downwards from the trapezoidal air nozzle 408. Subsequently, as the second electric push rod 405 continues to pull down, the trapezoidal air nozzle 408 can blow air from top to bottom in all directions on one side of the filter plate 106, thoroughly blowing away the mud and sludge inside the filter plate 106. Compared to traditional manual cleaning, this method can remove the mud and sludge inside the filter plate 106 more quickly and thoroughly. Moreover, the entire cleaning process is automated. With the control of the second electric push rod 405 and the air pump 401, the operator does not need to directly contact the sludge, which not only reduces the health risks to the operator but also improves work efficiency.

[0029] like Figure 8 As shown, the synchronization mechanism 2 includes a first rotating ring 203. A first connecting rod 201 and a second connecting rod 202 are rotatably mounted on the upper and lower ends of the outer surface of the first rotating ring 203, respectively. A second rotating ring 204 is rotatably mounted on both ends of the first connecting rod 201 and the second connecting rod 202. A wing bolt 206 can be slidably inserted into the second rotating ring 204. The threaded part of the wing bolt 206 can be threaded into the guide post 205. The guide post 205 is slidably mounted in the guide groove 108, which can lock the first connecting rod 201 and the second connecting rod 202, which form an X shape, onto the upper surface of the filter plate 106. The first rotating ring 203 is slidably pierced by the rigid tube 403, and the first rotating ring 203 is also located between the two sets of filter plates 106.

[0030] The rotational connection of multiple sets of first connecting rods 201 and second connecting rods 202 forms a scissor-type moving structure.

[0031] The first connecting rod 201 and the second connecting rod 202, which are scissor-shaped, are respectively threaded into guide columns 205 in the guide grooves 108 on the upper surface of the pressure plate 102 and the thrust plate 104 by wing bolts 206. The filter plate 106 can be moved synchronously and equidistantly by pushing and pulling the pressure plate 102.

[0032] Through the design of the first connecting rod 201, the second connecting rod 202, the first rotating ring 203, the second rotating ring 204, the guide post 205, and the wing bolt 206, when the multiple sets of filter plates 106 are stretched out, the hydraulic rod 101 can be activated to pull the clamping plate 102. The clamping plate 102 can pull the first connecting rod 201 and the second connecting rod 202 to rotate and close in a scissor-like manner on the outer surface of the first rotating ring 203. The other ends of the first connecting rod 201 and the second connecting rod 202 will also close together. The first connecting rod 201 and the second connecting rod 202 are... During the closing process, the guide column 205 will slide laterally in the guide groove 108. During the closing process, the first connecting rod 201 and the second connecting rod 202 will push the filter plate 106 connected to them to be pulled by the same distance. The connection of multiple sets of first connecting rods 201 and second connecting rods 202 realizes that pushing and pulling a set of pressing plate 102 will drive multiple sets of filter plates 106 to be pulled out synchronously and at equal distances. This ensures the smooth operation of the entire system and the consistency of the distance between the filter plates 106, which is conducive to maintaining the uniformity and efficiency of the filtration process. When the filter plate 106 needs to be removed, the operator can unscrew the wing bolts 206 on the filter plate 106 from the guide post 205, thereby releasing the restriction on the first connecting rod 201 and the second connecting rod 202 at the upper end of the filter plate 106. This allows the operator to slide and push the filter plate 106 individually or to move the first connecting rod 201 and the second connecting rod 202 to release the restriction of the wing bolts 206. This allows the filter plate 106 to avoid being covered by the top of the first connecting rod 201 and the second connecting rod 202, enabling the operator to remove the filter plate 106 from the main beam 1. This allows the operator to operate a single set of filter plates 106 without affecting other parts of the system, improving the system's flexibility and maintainability, and facilitating the inspection, cleaning, or replacement of individual filter plates 106.

[0033] Based on the above technical solution, the working steps of this solution are summarized as follows: When filtering sludge, the hydraulic rod 101 can be activated to push the pressing plate 102. During the pushing process, the pressing plate 102 will cause the first connecting rod 201 and the second connecting rod 202 on the upper surface to rotate and unfold in a scissor-like manner on the outer surface of the first rotating ring 203. The other ends of the first connecting rod 201 and the second connecting rod 202 will also unfold together. During the unfolding process, the first connecting rod 201 and the second connecting rod 202 will cause the guide column 205 to slide laterally in the guide groove 108. During the unfolding process, the first connecting rod 201 and the second connecting rod 202 will pull the filter plate 106 connected to them to be pulled closer together by an equal distance. A connecting rod 201 and a second connecting rod 202 are connected, enabling the pulling of a set of clamping plates 102 to drive multiple sets of filter plates 106 to be pulled together synchronously and at equal distances until the clamping plates 102, filter plates 106, and thrust plates 104 are completely pushed together, thus completing the assembly. Then, workers can discharge sludge from the feed inlet connected to one end of the thrust plate 104 into the multiple sets of press-fitted filter plates 106. As the sludge continuously enters the multiple sets of filter plates 106, the sludge residue is filtered out within the filter plates 106, while the liquid separated from the sludge can be discharged from the faucet connected to one end of the filter plates 106. After the sludge has been completely filtered, the hydraulic rod 101 can be activated again to pull the clamping plate 102 back, causing the clamping plate 102 to pull multiple sets of first connecting rods 206 together. Rod 201 and the second connecting rod 202 drive multiple sets of filter plates 106 to be pulled out synchronously and equidistantly. When the multiple sets of filter plates 106 are pulled out, the first rotating ring 203 between the first connecting rod 201 and the second connecting rod 202 also pulls the rigid tube 403 to always keep it between every two sets of filter plates 106. At the same time, the rigid tube 403 slides within the first U-shaped frame 407 and the second U-shaped frame 406 through the sliding block 404. The spacing of the rigid tube 403 is adjusted by the flexible hose 402 to pull it out. When the filter plates 106 are pulled out and the internal sludge needs to be cleaned, two sets of second electric push rods 405 can be activated. The two sets of second electric push rods 405 can pull down the first U-shaped frame 407 and the second U-shaped frame 406 vertically downward through the piston rod, which can make... The first U-shaped frame 407 and the second U-shaped frame 406 drive the internally sliding block 404 to slide the rigid tube 403 downwards within the synchronization mechanism 2 and insert it between each pair of filter plates 106. This allows the rigid tube 403 to drive the trapezoidal air nozzle 408 at its lower end to slide between each pair of filter plates 106. Subsequently, the air pump 401 can be activated to supply air to the hose 402, which in turn supplies compressed air into the rigid tube 403. This allows the rigid tube 403 to blow high-pressure gas out at a 45° angle downwards from the trapezoidal air nozzle 408. Then, as the second electric push rod 405 continues to pull down, the trapezoidal air nozzle 408 can blow air from top to bottom on one side of the filter plate 106 in an all-around manner, effectively blowing the sludge inside the filter plate 106 into the V-shaped cylinder 105.Then, the geared motor 301 can be started, which will drive the screw conveyor 302 to rotate and push the sewage in the V-shaped cylinder 105. This continuously pushes the sludge into the compaction cylinder 304, which is connected to the V-shaped cylinder 105. The continuous pushing of sludge into the compaction cylinder 304 compacts the sludge into a cylindrical shape identical to the cylinder. During the compression process, the liquid contained in the sludge can be discharged again from the drainage holes at the lower end of the outer surface of the compaction cylinder 304. When the compacted cylindrical sludge is discharged, the piston rod of the first electric pusher 303 can be activated to push the compaction cylinder 304 to rotate at one end of the main beam 1. With the continuous pushing of the first electric pusher 303, the compaction cylinder 304 can be rotated 90°, allowing the sludge inlet of the compaction cylinder 304 to face downwards, thus emptying the cylindrical sludge stored inside. Then, the first electric pusher 303 can be activated again to pull the compaction cylinder 304 back to connect it to the V-shaped cylinder 105 for the next sludge compaction operation.

[0034] In summary, the high-pressure gas purging system enables automated cleaning of the filter plates 106, thereby improving the continuous operation and cleaning efficiency of the equipment. It also eliminates the need for manual intervention to handle and remove the sludge cake. Through the coordinated work of these components, the entire filter press system achieves a highly efficient, automated, and clean sludge treatment process, which not only improves filtration efficiency but also reduces the need for manual operation and reduces environmental pollution.
