Description

Technical Field

[0001] The invention relates to the technical field of sludge treatment, in particular to a filter press for full-automatic ultra-high pressure sludge treatment. Background Art

[0002] The transportation cost is the main cost of sludge treatment. Dehydrating sludge can greatly reduce the transportation cost. For example, dehydrating sludge with a moisture content of 95% to 50% reduces the weight by 90%. Therefore, dehydrating sludge is of great significance. The current fully automatic ultra-high pressure sludge filter press mainly relies on placing the sludge between two layers of filter cloth to squeeze out the water in the sludge.

[0003] For example, a Chinese patent with announcement number CN210728782U discloses a sludge filter press, including a bracket, a precooling chamber arranged on the left side of the bracket, and a filter press mechanism installed on the right side of the precooling chamber; the lower end of the precooling chamber is connected to a horizontal water pump, the water pump is connected to a sewage treatment sedimentation tank, the outlet at the right end of the precooling chamber is connected to the filter press mechanism, a plurality of water outlet pipes are arranged outside the filter cloth of the filter press mechanism, a water collecting tank is arranged below the water outlet pipe, and the lower part of the water collecting tank is connected to the sewage treatment tank through a pipeline. The utility model has a simple structure, reduces the solubility of mud in water by cooling, improves the filter press efficiency, and adopts a water collecting tank to carry out sewage circulation treatment, thereby avoiding secondary pollution of squeezed water.

[0004] However, the above-mentioned sludge filter press cannot automatically discharge the mud cake and compress it into a column before discharging it during the process of filtering the sludge into mud cake. Manual intervention is required to handle and remove the mud cake, which affects the continuous operation of the equipment, affects the processing efficiency, increases the workload of the operator, and leads to an increase in maintenance and operating costs. Summary of the invention

[0005] The object of the present invention is to provide a fully automatic ultra-high pressure filter press for sludge treatment, so as to solve the problem in the above background technology that the sludge cake cannot be automatically discharged during the process of filtering the sludge into a sludge cake.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0009] Wherein, a purge mechanism is slidably installed in the synchronization mechanism, and the blowing end of the purge mechanism slides through the synchronization mechanism and is located between two groups of trapezoidal grooves. The trapezoidal grooves are opened on the upper surface of each group of filter plates, so that when the filter plates are synchronously stretched and the same equidistant distance is reached, the purge end of the purge mechanism can penetrate into the gap between them to purge the mud cake;

[0010] Among them, a V-shaped cylinder is fixedly installed on the lower surface of the main beam, and a mud solidification mechanism is rotatably installed in the V-shaped cylinder. The V-shaped cylinder is located directly below the multiple groups of filter plates and can receive the mud swept by the sweeping mechanism and compact and discharge it.

[0011] Preferably, the mud solidification mechanism includes a reduction motor, the reduction motor is fixedly installed at one end of the V-shaped cylinder, the output shaft of the reduction motor passes through the V-shaped cylinder and a spiral conveying rod is fixedly installed, the spiral conveying rod is rotatably installed at the bottom of the V-shaped cylinder, the spiral conveying rod can push the mud into the compacting cylinder, the compacting cylinder is rotatably installed at one end of the main beam, and the compacting cylinder can be turned 90° to communicate with the V-shaped cylinder;

[0012] Wherein, the lower half of the outer surface of the compacting cylinder is provided with hydrophobic holes.

[0013] Preferably, both sides of the outer surface of the compacting cylinder are rotatably connected to the piston rod of the first electric push rod, and the first electric push rod is rotatably installed on the inner side of the support leg of the main beam, so that the first electric push rod can push and pull the compacting cylinder to flip 90° at one end of the main beam, so as to connect the compacting cylinder with the V-shaped cylinder for the mud residue to be pushed in and flipped and unfolded for the mud residue compacted into a mud column to be poured out therefrom.

[0014] Preferably, the purge mechanism includes an air pump, which is fixedly installed on one end of the support plate, and the support plate is fixedly installed on one end of the pressure plate. One end of the air inlet of the air pump is connected to a hose, and the other end of the hose is connected to a hard pipe, and the other end of the hard pipe is connected to a trapezoidal air nozzle, so that the trapezoidal air nozzle can blow the compressed gas toward the lower ends on both sides at 45°.

[0015] Preferably, the hard tube slides out from the synchronization mechanism and drives the trapezoidal air nozzle to be located between the two groups of trapezoidal grooves of the two groups of filter plates.

[0016] Preferably, a sliding block is fixedly mounted on the outer surface of the upper end of the hard tube, and both sides of the sliding block slide out from both sides of the first U-shaped frame and the second U-shaped frame, and the first U-shaped frame slides in the second U-shaped frame, and the first U-shaped frame and the second U-shaped frame are fixedly mounted on the upper surfaces of the piston rods of the two groups of second electric push rods, and the two groups of the second electric push rods are fixedly mounted on the mounting plate and the inner upper surface of the thrust plate respectively;

[0017] Among them, the first U-shaped frame and the second U-shaped frame can be supported by the piston rods of two groups of second electric push rods, so that when the support plate drives one group of the second electric push rods to pull, one group of the second electric push rods can drive the first U-shaped frame to slide out of the second U-shaped frame and extend.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Through the design of filter plates, hydraulic rods, clamping plates, thrust plates, V-shaped cylinders, synchronous mechanisms, sludge solidification mechanisms and purge mechanisms, when the sludge is filtered, the hydraulic rod can be started to push the clamping plate, and the process of pushing the clamping plate will drive the synchronous mechanism on the upper surface to move together, and the synchronous mechanism will drive multiple groups of filter plates to reduce the spacing synchronously and equidistantly in the main beam until the clamping plate, filter plate and thrust plate are completely pushed together to complete the assembly. Then the staff can discharge the sludge from the feed port connected to one end of the thrust plate into the multiple groups of filter plates pressed together, and the sludge will continue to enter the multiple groups of filter plates. The sludge is filtered in the filter plate, and the liquid separated from the sludge can be discharged from the faucet installed at one end of the filter plate. After the sludge is filtered, the hydraulic rod can be started again to pull the pressing plate back. The pressing plate will drive the synchronization mechanism again during the process of being pulled back, and the synchronization mechanism can synchronously stretch out multiple groups of filter plates. As the pressing plate is continuously pulled, the synchronization mechanism can be driven to expand the spacing between the multiple groups of filter plates. The spacing between each group of filter plates is equal, which can ensure that the multiple groups of filter plates can maintain synchronous equidistantness during the compression and stretching process, avoiding uneven filtration caused by uneven distances between filter plates. The problem of uniformity is solved, and the filter plates are arranged neatly and operated. In the process of the synchronous mechanism stretching multiple groups of filter plates, the purge mechanism will also be driven to move between every two groups of filter plates. Then the purge mechanism can be started to slide into between each group of filter plates and purge the high-pressure gas. The high-pressure gas blown out is inclined downward at 45°, which can blow the mud residue on both sides of each group of filter plates down and make it fall into the V-shaped cylinder. The mud residue on both sides of the filter plates is blown by high-pressure gas, thereby realizing the function of automatic cleaning, improving the continuous operation ability and cleaning efficiency of the equipment, and eliminating the need for manual intervention to handle and remove the mud cake, and reducing Maintenance and operation costs, and the sludge solidification mechanism can be started after the sludge is blown into the V-shaped cylinder, and the sludge solidification mechanism can push the sludge centrally and compress it into a cylindrical shape, and the sludge compacted into a cylindrical shape will be automatically discharged to the outside by the sludge solidification mechanism, and the sludge is concentrated and compressed into a cylindrical shape, which is convenient for the storage, transportation and subsequent utilization or treatment of the sludge, reduces the volume, and improves the treatment efficiency. Through the coordinated work of these components, the entire filter press system is increased to realize an efficient, automated and clean sludge treatment process, which not only improves the filtration efficiency, but also reduces the demand for manual operation and reduces environmental pollution.

[0020] 2. Through the design of the reduction motor, the spiral conveying rod, the first electric push rod and the compacting cylinder, when the sludge is blown into the V-shaped cylinder by the blowing mechanism, the reduction motor can be started, and the reduction motor will drive the spiral conveying rod to rotate in the V-shaped cylinder to push the sewage, and the sludge can be continuously pushed into the compacting cylinder connected to the V-shaped cylinder. Continuously pushing the sludge into the compacting cylinder can compact the sludge into the same cylindrical shape as the compacting cylinder, and in the process of squeezing, the liquid contained in the sludge can be discharged again from the drain hole opened at the lower end of the outer surface of the compacting cylinder. When the sludge compacted into a cylindrical shape needs to be discharged, the first electric push rod can be started. The piston rod of the dynamic push rod pushes the compacting cylinder to flip at one end of the main beam, and with the continuous pushing of the first electric push rod, the compacting cylinder can be pushed and flipped 90°, so that the mud inlet of the compacting cylinder can face downward to dump out the cylindrical mud residue stored inside, and the sludge can be compacted into a cylindrical shape. This process can significantly reduce the volume of the mud residue and improve the processing efficiency, while ensuring the consistency and stability of the mud column volume. The automatic discharge of the mud column reduces the residence time of the sludge in the equipment, which helps to keep the equipment clean. The cleaning and maintenance process also becomes simpler, which is conducive to the long-term stable operation of the equipment.

[0021] 3. Through the design of the air pump, the hose, the hard pipe, the sliding block, the second electric push rod, the second U-shaped frame, the first U-shaped frame and the trapezoidal air nozzle, when multiple groups of filter plates are pulled and unfolded at equal intervals by the synchronous mechanism, the synchronous mechanism will also pull the hard pipe together to always keep it between every two groups of filter plates, and at the same time, the hard pipe will slide in the first U-shaped frame and the second U-shaped frame through the sliding block, and the spacing of the hard pipe will be pulled and unfolded through the hose. When the filter plates are pulled and unfolded and the internal mud residue needs to be cleaned, the two groups of second electric push rods can be started, and the two groups of second electric push rods can pull down the first U-shaped frame and the second U-shaped frame vertically downward through the piston rod, so that the first U-shaped frame and the second U-shaped frame can drive the sliding block installed internally to drive the hard pipe to slide downward in the synchronous mechanism and insert between every two groups of filter plates. During this time, the hard tube can drive the trapezoidal air nozzle at the lower end to slide between every two groups of filter plates, and then the air pump can be started to supply air to the hose, and the hose can supply compressed air into the hard tube, so that the hard tube can blow the high-pressure gas out from the trapezoidal air nozzle at a 45° downward angle, and then as the second electric push rod continues to be pulled down, the trapezoidal air nozzle can blow all-round from top to bottom on one side of the filter plate, and the mud residue in the filter plate can be fully blown down. Compared with traditional manual cleaning, this method can remove the mud residue in the filter plate more quickly and thoroughly, and the entire cleaning process is automated. With the control of the second electric push rod and the air pump, 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.

[0022] 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 groups of filter plates are stretched out, the pressure plate can be pulled by starting the hydraulic rod, and the pressure 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, and the other ends of the first connecting rod and the second connecting rod will also be closed together. In the process of the first connecting rod and the second connecting rod being pulled and closed, the guide column will be driven to slide horizontally in the guide groove together, and the first connecting rod and the second connecting rod will push the filter plates connected thereto to be pulled an equal distance together during the closing process. Multiple groups of first connecting rods and second connecting rods are connected, so that one group of pressure plates can be pushed and pulled to drive multiple groups of filter plates to be stretched out synchronously and equidistantly, thereby ensuring the smoothness of the 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;

[0023] When the filter plate needs to be removed, the staff can unscrew the butterfly bolts on the filter plate to be removed from the guide column to release the restrictions on the first connecting rod and the second connecting rod at the upper end of the filter plate. The staff can then slide this group of filter plates individually or move the first connecting rod and the second connecting rod to release the restrictions of the butterfly bolts, so that the filter plates can avoid the top cover of the first connecting rod and the second connecting rod, allowing the staff to remove this group of filter plates from the main beam, thereby allowing the staff to operate a certain group of filter plates individually without affecting other parts of the entire system, thereby improving the flexibility and maintainability of the system and facilitating the inspection, cleaning or replacement of a single filter plate.

[0035] like Figure 1-Figure 3 As shown, a fully automatic ultra-high pressure sludge treatment filter press comprises: a main beam 1, in which a plurality of filter plates 106 are slidably installed, thrust plates 104 and mounting plates 107 are fixedly installed at both ends of the main beam 1, a hydraulic rod 101 is fixedly installed at one end of the mounting plate 107, a piston rod of the hydraulic rod 101 passes through the mounting plate 107 and a clamping plate 102 is fixedly installed at the end, the clamping plate 102 can press the plurality of filter plates 106 against one end of the thrust plate 104 through the push of the hydraulic rod 101, so that the plurality of filter plates 106 can be connected to the feed port connected and installed at one end of the thrust plate 104, and a faucet is connected and installed at one end of each filter plate 106;

[0036] The upper surfaces of the multiple filter plates 106, the mounting plate 107 and the thrust plate 104 are all provided with guide grooves 108, in which the synchronization mechanism 2 is slidably installed, and the synchronization mechanism 2 can make the multiple filter plates 106 expand and contract in an equidistant and synchronous manner when being pushed and pulled;

[0037] Among them, a purge mechanism 4 is slidably installed in the synchronous mechanism 2, and the blowing end of the purge mechanism 4 slides through the synchronous mechanism 2 and is located between two groups of trapezoidal grooves 109. The trapezoidal grooves 109 are opened on the upper surface of each group of filter plates 106, so that when the filter plates 106 are synchronously stretched and the same equidistant, the purge end of the purge mechanism 4 can penetrate into the gap between them to purge the mud cake;

[0038] 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 in the V-shaped cylinder 105. The V-shaped cylinder 105 is located directly below the multiple groups of filter plates 106, and can receive the mud swept by the sweeping mechanism 4 and compact it and discharge it.

[0039] Through the design of the filter plate 106, the hydraulic rod 101, the clamping plate 102, the thrust plate 104, the V-shaped cylinder 105, the synchronous mechanism 2, the sludge solidification mechanism 3 and the purge mechanism 4, when the sludge is filtered, the hydraulic rod 101 can be started to push the clamping plate 102, and the clamping plate 102 will drive the synchronous mechanism 2 on the upper surface to move together during the pushing process, and the synchronous mechanism 2 will drive multiple groups of filter plates 106 to reduce the spacing synchronously and equidistantly in the main beam 1 until the clamping plate 102, the filter plate 106 and the thrust plate 104 are completely pushed together to complete the assembly, and then the staff can discharge the sludge from the feed port connected to the end of the thrust plate 104 into the multiple groups of filter plates 1 pressed together. 06, and the sludge continuously enters the multiple groups of filter plates 106, and the mud residue therein will be filtered in the filter plates 106, and the liquid separated from the sludge can be discharged from the faucet installed at one end of the filter plates 106, until the sludge is filtered, the hydraulic rod 101 can be started again to pull the pressing plate 102 back, and the pressing plate 102 will drive the synchronous mechanism 2 again in the process of being pulled back, and the synchronous mechanism 2 can synchronously stretch out the multiple groups of filter plates 106, and as the pressing plate 102 is continuously pulled, it can drive the synchronous mechanism 2 to expand the spacing between the multiple groups of filter plates 106 to be larger, and the spacing between each group of filter plates 106 is equal, which can ensure that the multiple groups of filter plates 106 can be stretched during the compression and stretching process. The sludge on both sides of the filter plates 106 can be swept down by the high-pressure gas, and the sludge on both sides of the filter plates 106 can be swept down by the high-pressure gas, thereby realizing the function of automatic cleaning, improving the continuous operation capability and cleaning efficiency of the equipment, and It also eliminates the need for manual intervention to handle and remove the mud cake, and reduces maintenance and operating costs. After the mud is blown into the V-shaped cylinder 105, the mud solidification mechanism 3 can be started, and the mud solidification mechanism 3 can push the mud together and compress it into a cylindrical shape. The mud compacted into a cylindrical shape will be automatically discharged to the outside by the mud solidification mechanism 3, and the mud is concentrated and compressed into a cylindrical shape, which is convenient for the storage, transportation and subsequent utilization or treatment of the mud, reduces the volume, and improves the treatment efficiency. Through the coordinated work of these components, the entire filter press system realizes an efficient, automated and clean sludge treatment process, which not only improves the filtration efficiency, but also reduces the demand for manual operation and reduces environmental pollution.

[0040] like Figure 4-Figure 5As shown, the mud 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 is fixedly installed with a screw conveying rod 302. The screw conveying rod 302 is rotatably installed at the bottom of the V-shaped cylinder 105. The screw conveying rod 302 can push the mud into the compacting cylinder 304. The compacting cylinder 304 is rotatably installed at one end of the main beam 1. The compacting cylinder 304 can be turned 90° to communicate with the V-shaped cylinder 105.

[0041] The lower half of the outer surface of the compacting cylinder 304 is provided with hydrophobic holes.

[0042] The two sides of the outer surface of the compacting cylinder 304 are rotatably connected to the piston rod of the first electric push rod 303, and 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 compacting cylinder 304 to flip 90° at one end of the main beam 1, so as to connect the compacting cylinder 304 with the V-shaped cylinder 105 for the mud residue to be pushed in and flipped and unfolded for the mud residue compacted into a mud column to be poured out.

[0043] Through the design of the reduction motor 301, the spiral conveying rod 302, the first electric push rod 303 and the compacting cylinder 304, when the sludge is blown into the V-shaped cylinder 105 by the blowing mechanism 4, the reduction motor 301 can be started, and the reduction motor 301 will drive the spiral conveying rod 302 to rotate in the V-shaped cylinder 105 to push the sewage, and can continuously push the sludge into the compacting cylinder 304 connected to the V-shaped cylinder 105, and continuously pushing the sludge into the compacting cylinder 304 can compact the sludge into the same cylindrical shape as the compacting cylinder 304, and in the process of squeezing, the liquid contained in the sludge can be discharged again from the hydrophobic holes opened at the lower end of the outer surface of the compacting cylinder 304, and the compacting cylinder 304 needs to be compacted into a cylindrical shape. When the sludge is discharged, the piston rod of the first electric push rod 303 can be started to push the compacting cylinder 304 to flip over at one end of the main beam 1, and with the continuous pushing of the first electric push rod 303, the compacting cylinder 304 can be pushed and flipped 90°, so that the mud inlet of the compacting cylinder 304 can face downward to pour out the cylindrical mud residue stored inside, and the sludge can be compacted into a cylindrical shape. This process can significantly reduce the volume of the mud residue and improve the processing efficiency, while ensuring the consistency and stability of the mud column volume. The automatic discharge of the mud column reduces the residence time of the sludge in the equipment, which helps to keep the equipment clean. The cleaning and maintenance process also becomes simpler, which is conducive to the long-term stable operation of the equipment.

[0044] like Figure 6-Figure 7As shown, the purge mechanism 4 includes an air pump 401, which is fixedly mounted on one end of the support plate 103, and the support plate 103 is fixedly mounted on one end of the clamping plate 102. One end of the air port of the air pump 401 is connected to a hose 402, and the other end of the hose 402 is connected to a hard tube 403, and the other end of the hard tube 403 is connected to a trapezoidal air nozzle 408, so that the trapezoidal air nozzle 408 can blow the compressed gas at 45° to the lower ends on both sides.

[0045] The hard tube 403 slides out from the synchronization mechanism 2 and drives the trapezoidal air nozzle 408 to be located between the two groups of trapezoidal grooves 109 of the two groups of filter plates 106 .

[0046] A sliding block 404 is fixedly mounted on the outer surface of the upper end of the hard tube 403. Both sides of the sliding block 404 slide out from both sides of the first U-shaped frame 407 and the second U-shaped frame 406. The first U-shaped frame 407 slides in the second U-shaped frame 406. The first U-shaped frame 407 and the second U-shaped frame 406 are fixedly mounted on the upper surfaces of the piston rods of two groups of second electric push rods 405. The two groups of second electric push rods 405 are fixedly mounted on the mounting plate 107 and the inner upper surface of the thrust plate 104 respectively.

[0047] Among them, the first U-shaped frame 407 and the second U-shaped frame 406 can be supported by the piston rods of the two groups of second electric push rods 405, so that when the support plate 103 drives one group of the second electric push rods 405 to pull, one group of the second electric push rods 405 can drive the first U-shaped frame 407 to slide out from the second U-shaped frame 406 and extend.

[0048] The filter plate 106 pulled out by the synchronization mechanism 2 can be used by two groups of second electric push rods 405 to pull down the first U-shaped frame 407 and the second U-shaped frame 406 to move vertically downward, so that the first U-shaped frame 407 and the second U-shaped frame 406 can drive the hard tube 403 to slide downward in the synchronization mechanism 2, and the hard tube 403 can drive the trapezoidal air nozzle 408 at the lower end to slide into between every two groups of filter plates 106.

[0049] Through the design of the air pump 401, the hose 402, the hard tube 403, the sliding block 404, the second electric push rod 405, the second U-shaped frame 406, the first U-shaped frame 407 and the trapezoidal air nozzle 408, when the multiple groups of filter plates 106 are pulled and spread out at equal distances by the synchronization mechanism 2, the synchronization mechanism 2 will also pull the hard tube 403 to always remain between every two groups of filter plates 106, and at the same time, the hard tube 403 will pass through the sliding block 404 between the first U-shaped frame 407 and the second U-shaped frame 408. 6, and the spacing of the hard tube 403 increases, which will be pulled and expanded through the hose 402. When the filter plate 106 is pulled and expanded and the internal mud residue needs to be cleaned, the two sets of second electric push rods 405 can be started, and 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 through the piston rod to move vertically downward, so that the first U-shaped frame 407 and the second U-shaped frame 406 can drive the sliding block 404 installed internally to drive the hard tube 403 to move synchronously. The mechanism 2 slides downward and is inserted between every two groups of filter plates 106, so that the hard tube 403 can drive the trapezoidal air nozzle 408 at the lower end to slide between every two groups of filter plates 106, and then the air pump 401 can be started to supply air to the hose 402, and the hose 402 can supply compressed air into the hard tube 403, so that the hard tube 403 can blow the high-pressure gas out from the trapezoidal air nozzle 408 at a 45° downward angle, and then as the second electric push rod 405 continues to be pulled down, the trapezoidal air nozzle 408 can blow all-round from top to bottom on one side of the filter plate 106, so that the mud residue in the filter plate 106 can be fully blown down. Compared with traditional manual cleaning, this method can remove the mud residue in the filter plate 106 more quickly and thoroughly, and 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.

[0050] like Figure 8 As shown, the synchronization mechanism 2 includes a first rotating ring 203, and the first connecting rod 201 and the second connecting rod 202 are rotatably installed on the upper end and the lower end of the outer surface of the first rotating ring 203 respectively, and the first connecting rod 201 and the second connecting rod 202 are rotatably installed on both ends of the second rotating ring 204, and a butterfly bolt 206 can be slidably inserted in the second rotating ring 204, and the threaded portion of the butterfly bolt 206 can be threadedly installed in the guide column 205, and the guide column 205 is slidably installed in the guide groove 108, so that the first connecting rod 201 and the second connecting rod 202 forming an X shape can be locked and installed on the upper surface of the filter plate 106;

[0051] The hard tube 403 is slidably passed through the first rotating ring 203 , and the first rotating ring 203 is also located between the two groups of filter plates 106 .

[0052] The rotational connection of multiple groups of first connecting rods 201 and second connecting rods 202 forms a scissor-type moving structure.

[0053] The head and tail parts of the first connecting rod 201 and the second connecting rod 202 that form a scissor-type are threadedly installed in the guide columns 205 that are slidably installed in the guide grooves 108 on the upper surfaces of the clamping plate 102 and the thrust plate 104 through butterfly bolts 206, and can achieve synchronous and equidistant movement of the filter plate 106 through the push and pull of the clamping plate 102.

[0054] 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 column 205 and the butterfly bolt 206, when the multiple groups of filter plates 106 are pulled out, the pressing plate 102 can be pulled by starting the hydraulic rod 101, and the pressing 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, and the other ends of the first connecting rod 201 and the second connecting rod 202 will also be closed together, and the first connecting rod 201 and the second connecting rod 202 are During the process of pulling and closing, the guide column 205 will be driven to slide horizontally in the guide groove 108, and the first connecting rod 201 and the second connecting rod 202 will push the filter plates 106 connected thereto to be pulled together by an equal distance during the closing process. Multiple groups of first connecting rods 201 and second connecting rods 202 are connected, so that one group of pressing plates 102 is pushed and pulled to drive multiple groups of filter plates 106 to be pulled and unfolded synchronously and equidistantly, thereby ensuring the smoothness of the 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.

[0055] When the filter plate 106 needs to be removed, the staff can unscrew the butterfly bolt 206 on the filter plate 106 to be removed from the guide column 205, thereby releasing the restriction of the first connecting rod 201 and the second connecting rod 202 on the upper end of the filter plate 106. The staff can then slide this group of filter plates 106 individually or move the first connecting rod 201 and the second connecting rod 202 that release the restriction of the butterfly bolt 206, so that the filter plate 106 can avoid the top cover of the first connecting rod 201 and the second connecting rod 202, and the staff can remove this group of filter plates 106 from the main beam 1, thereby allowing the staff to operate a certain group of filter plates 106 individually without affecting other parts of the entire system, thereby improving the flexibility and maintainability of the system and facilitating the inspection, cleaning or replacement of a single filter plate 106.

[0056] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when the sludge is filtered, the pressing plate 102 can be pushed by starting the hydraulic rod 101, and the pressing plate 102 will drive 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 during the pushing process, and the other ends of the first connecting rod 201 and the second connecting rod 202 will also unfold together, and the first connecting rod 201 and the second connecting rod 202 will drive the guide column 205 to slide horizontally in the guide groove 108 during the pulling and unfolding process, and the first connecting rod 201 and the second connecting rod 202 will pull the filter plate 106 connected thereto to be pulled together to an equal distance during the unfolding process, and multiple groups of first connecting rods 201 and 202 will be pulled together to form a plurality of first connecting rods 201 and 202. A connecting rod 201 is connected to a second connecting rod 202, so that one group of clamping plates 102 is pulled to drive multiple groups of filter plates 106 to be pulled together synchronously and equidistantly, until the clamping plates 102, filter plates 106 and thrust plates 104 are completely pushed together to complete the assembly, and then the staff can discharge the sludge from the feed port connected and installed at one end of the thrust plate 104 into the multiple groups of filter plates 106 pressed together, and the sludge will continue to enter the multiple groups of filter plates 106. The mud residue therein will be filtered in the filter plates 106, and the liquid separated from the sludge can be discharged from the faucet connected and installed at one end of the filter plates 106, until the sludge is filtered, the hydraulic rod 101 can be started again to pull the clamping plate 102 back, so that the clamping plate 102 can pull multiple groups of first connecting rods 101 to pull the multiple groups of first connecting rods 102 ... The rod 201 and the second connecting rod 202 drive the multiple groups of filter plates 106 to be pulled and unfolded synchronously and equidistantly. When the multiple groups of filter plates 106 are pulled and unfolded, the first rotating ring 203 between the first connecting rod 201 and the second connecting rod 202 will also pull the hard tube 403 together to always remain between every two groups of filter plates 106, and at the same time, the hard tube 403 will slide in the first U-shaped frame 407 and the second U-shaped frame 406 through the sliding block 404, and the spacing of the hard tube 403 will be pulled and unfolded through the hose 402. When the filter plates 106 are pulled and unfolded and the internal mud residue needs to be cleaned, the two groups of second electric push rods 405 can be started, and the two groups 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 sliding block 404 installed internally to drive the hard tube 403 to slide downward in the synchronization mechanism 2 and insert between every two groups of filter plates 106, so that the hard tube 403 can drive the trapezoidal air nozzle 408 at the lower end to slide into between every two groups of filter plates 106, and then the air pump 401 can be started to supply air to the hose 402, and the hose 402 can supply compressed air into the hard tube 403, so that the hard tube 403 can blow the high-pressure gas out from the trapezoidal air nozzle 408 at a 45° downward angle, and then as the second electric push rod 405 continues to be pulled down, the trapezoidal air nozzle 408 can blow all-round from top to bottom on one side of the filter plate 106, so that the mud residue in the filter plate 106 can be fully blown into the V-shaped cylinder 105,Then, the reduction motor 301 can be started, and the reduction motor 301 will drive the spiral conveying rod 302 to rotate in the V-shaped cylinder 105 to push the sewage, and can continuously push the sludge into the compacting cylinder 304 connected to the V-shaped cylinder 105. Continuously pushing the sludge into the compacting cylinder 304 can compact the sludge into the same cylindrical shape as the compacting cylinder 304, and in the process of squeezing, the liquid contained in the sludge can be discharged again from the hydrophobic holes opened at the lower end of the outer surface of the compacting cylinder 304, and it is necessary to When the sludge compacted into a cylindrical shape is discharged, the piston rod of the first electric push rod 303 can be started to push the compacting cylinder 304 to flip at one end of the main beam 1, and as the first electric push rod 303 continues to push, the compacting cylinder 304 can be pushed and flipped 90 degrees, so that the mud inlet of the compacting cylinder 304 can face downward to dump the cylindrical mud stored inside, and then the first electric push rod 303 can be started again to pull the compacting cylinder 304 to connect with the V-shaped cylinder 105 again for the next compacting mud operation.

[0057] In summary: by blowing it with high-pressure gas, the function of automatically cleaning the filter plate 106 is realized, thereby improving the continuous operation capability and cleaning efficiency of the equipment, while also eliminating the need for manual intervention to handle and remove the mud cake. Through the coordinated work of these components, the entire filter press system is increased to achieve an efficient, automated and clean sludge treatment process, which not only improves the filtration efficiency, but also reduces the need for manual operation and reduces environmental pollution.
