Description

Technical Field

[0001] The present invention relates to the technical field of sludge treatment, in particular to an ultra-high pressure unidirectional propulsion compression type sludge deep compression and dehydration device. Background Art

[0002] During sludge treatment, sludge must be dried and dehydrated to reduce its water content. This reduces the water content of the sludge to a level that meets relevant standards before discharge, facilitating subsequent sludge treatment. Sludge drying is the process of removing most of the water from the sludge through filtration or evaporation.

[0003] Usually, a sludge filter press is used for pressing and dehydration. However, in the process of pressing and dehydration, the sludge water squeezed out flows straight downward. The sludge contains a relatively high ammonia content. The straight downward flow and the air produce friction oxidation, which promotes the accelerated release of ammonia and causes glare and damage to the surrounding environment. The aerosol of the squeezed water contains a large number of fine particles that can enter the capillary and have a certain impact on the human body. After pressing and dehydration, the mud cake needs to be manually shoveled off the filter cloth. Each pressing and dehydration plate needs to be equipped with a staff member to shovel mud and monitor, which greatly reduces the work efficiency of sludge pressing and dehydration and affects the health of sludge pressing and dehydration workers.

[0004] To this end, China's patent: an ultra-high-pressure bidirectional piston-type sludge deep compression and dehydration equipment, patent announcement number: CN219333280U, patent announcement date: 2023.07.14, discloses a compression and dehydration equipment, which drives the pressing plate to move against the pressing component through a hydraulic system to squeeze the sludge, and the first pressing plate and the second pressing plate of the pressing component move toward the first filter plate, which can make the accommodating cavity gradually shrink when the first pressing plate and the second pressing plate approach each other, realizing bidirectional squeezing, effectively improving the squeezing efficiency, achieving energy-saving and high-efficiency effects, and saving labor costs. After the squeezing is completed, the mud cake can be detached to the assembly line base through the pneumatic component and transported and unloaded through the assembly line, which can reduce the contact of the staff with the sludge and effectively protect the health of the staff. However, this equipment has the following defects: before the sludge is pumped in, the first pressure plate and the second pressure plate must be pressed tightly against the first filter plate. Moreover, because the first filter plate and the second filter plate are brought closer or separated by a cylinder, the entire equipment has a large number of pneumatic components of this type. When one pneumatic component fails, the chamber seal is not tight, which can easily cause slurry leakage. Secondly, each pneumatic component must cooperate with the hydraulic system, and the large number of pneumatic components often leads to asynchronous control, which can cause slurry leakage. At the same time, the large number of pneumatic components leads to high costs and high maintenance rates. Therefore, the above equipment needs to be improved to reduce costs, reduce maintenance rates, and reduce the risk of slurry leakage. Summary of the Invention

[0005] In response to the above problems, the present invention provides an ultra-high pressure unidirectional propulsion compression type sludge deep compression and dehydration equipment to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0037] The technical solution of the present invention is described below with reference to the accompanying drawings and embodiments.

[0038] Reference Figures 1 to 15The ultra-high-pressure unidirectional propulsion compression type sludge deep compression and dehydration equipment described in the present invention includes a frame 1, a collecting component 2 arranged at the lower part of the frame 1, and a filter press component 3 arranged above the collecting component 2. The collecting component 2 is a conveyor belt arranged along the length direction of the frame 1. The mud cake filtered by the filter press component 3 falls into the collecting component 2. The filter press component 3 includes a pressure cylinder 4 arranged at one end of the frame 1, a movable plate 5 driven by the pressure cylinder 4, a fixed plate 6 arranged on the frame 1, and multiple groups of compression modules 7 located above the collecting component 2 that are slidably arranged between the fixed plate 6 and the movable plate 5. The pressure cylinder 4 adopts an oil cylinder, and two adjacent compression modules 7 cooperate with each other. The pressure cylinder 4 drives the movable plate 5 to compress all the compression modules 7, so that the sludge in the compression module 7 is dehydrated. The compression module 7 includes a compression male mold 71 located on the front and a compression female mold 72 located on the back. The compression male mold 71 on the compression module 7 cooperates with the compression female mold 72 on the adjacent compression module 7 to form a compression mold cavity 73. The compression male mold 71 can be pressed into the compression female mold 72 and make the space of the compression mold cavity 73 smaller. The surfaces of the compression male mold 71 and the compression female mold 72 are both provided with filter cloths. The compression mold cavity 73 passes through the filter cloth and is connected to a silt pipe 8. Therefore, the silt pipe 8 sends the silt into the compression mold cavity 73. The compression mold cavity 73 is connected to a water outlet pipe 9 through the filter cloth. The water outlet pipe 9 remains normally open. The water outlet pipe 9 is located below the compression mold cavity 73. The moisture in the compression mold cavity 73 can pass through the filter cloth and enter the water outlet pipe 9. A sealing gasket 10 is provided on the compression female mold 72. The compression male mold 71 is pressed on the sealing gasket 10. The sealing gasket 10 can be deformed along the depth direction of the compression female mold 72. When the compression male mold 71 increases the pressure on the sealing gasket 10, the space of the compression mold cavity 73 will be compressed and become smaller. Pulling trolleys 11 are also provided on both sides of the upper part of the frame 1 for pulling the compression module 7 apart. The pulling trolley 11 is a traditional and mature technology and will not be described in detail.

[0039] Specifically, the compression mold cavity 73 is connected to a blowing pipe 12, and the blowing pipe 12 is used to blow air into the compression mold cavity 73 to facilitate demolding of the mud cake.

[0040] Specifically, the silt pipe 8, the water outlet pipe 9 and the air blowing pipe 12 are all inserted into the compression module 7 and then passed out from the compression mother mold 72. In this way, the silt in the silt pipe 8 can be taken out together during demoulding. The silt taken out of the silt pipe 8 from this direction will not damage the mud cake, so that the shape of the mud cake is consistent.

[0041] Specifically, sliders 13 are provided on both sides above each compression module 7 , and slide rails 14 are provided above the frame 1 . The sliders 13 are slidably arranged on the slide rails 14 , and the pulling trolley 11 pulls the compression modules 7 apart one by one.

[0042] Specifically, the compression female mold 72 is provided with a concave compression hole 74, the compression male mold 71 is provided with a convex compression platform 75, and a plurality of stacked sealing gaskets 10 are provided in the compression hole 74. The sealing gaskets 10 are against the side walls of the compression hole 74, so that the sealing gaskets 10 cannot be deformed outward. The bottom sealing gasket 10 is fixed in the compression hole 74 by screws, and the remaining sealing gaskets 10 are provided with through holes for the ends of the screws to pass through, and there are through holes between adjacent sealing gaskets 10. When installing the sealing gasket 10, align the through hole of the upper sealing gasket 10 with the screw hole of the lowest sealing gasket 10 and glue them together. After the whole is glued together, align the screw hole in the compression hole 74 and insert the sealing gasket 10. Then use the screw to tighten the lowest sealing gasket 10 in the compression hole 74. In this way, the end of the screw is close to the lowest sealing gasket 10. When the sealing gasket 10 is compressed and deformed as a whole, the end of the screw will not interfere with the compression platform 75.

[0043] Specifically, the surface of the outermost sealing gasket 10 is smooth. Except for the through hole, the outermost sealing gasket 10 has no other holes, that is, the outermost sealing gasket 10 can ensure airtightness. The middle part of the inner sealing gasket 10 is provided with a plurality of clearance holes, and the clearance holes can be arc-shaped holes. Because the sealing gasket 10 will deform when compressed, if the sealing gasket 10 does not have a clearance hole, the sealing gasket 10 will deform toward its inner side, affecting the shape of the mud cake and causing the edge of the mud cake to be uneven.

[0044] Specifically, recessed channels 76 are provided on the surfaces of the compression male mold 71 and the compression female mold 72 for the filtered water to flow through, and all the channels 76 are connected together and connected to the water outlet pipe 9 .

[0045] Specifically, a large pressure ring 77 is provided on the surface of the compression male mold 71 near its outer edge for pressing the filter cloth. The compression male mold 71 is provided with a matching recess 78. The large pressure ring 77 is set in the recess 78 and fixed with screws. The top surface of the large pressure ring 77 does not exceed the surface of the compression male mold 71.

[0046] Specifically, the compression mother mold 72 is provided with a sludge water inlet hole 79, and the filter cloth is provided with a through hole corresponding to the sludge water inlet hole 79. The filter cloth is fixed to the periphery of the sludge water inlet hole 79 by a small pressure ring 710 at the position of the through hole corresponding to the filter cloth.

[0047] When the present invention is working: the pressure cylinder 4 drives the movable plate 5 to move, the movable plate 5 squeezes the compression module 7, and the compression male mold 71 and the compression female mold 72 between adjacent compression modules 7 cooperate to form a compression mold cavity 73. At this time, the pressure cylinder 4 is maintained at a first pressure value, and the silt pipe 8 inputs silt into the mold cavity. After the silt fills the compression mold cavity 73, the silt pipe 8 is closed, and the pressure cylinder 4 continues to pressurize and reaches a second pressure value. The second pressure value is greater than the first pressure value. The second pressure value uses an ultra-high pressure of 150-200 tons to compress the silt. The sealing gasket 10 is compressed, and the space of the compression mold cavity 73 becomes smaller. The moisture in the silt will enter the water outlet pipe 9 through the filter cloth, and finally the silt is compressed into a mud cake. The pressure cylinder 4 releases pressure and resets, and the pulling plate trolley 11 pulls the compression modules 7 apart one by one. When the compression module 7 is pulled apart, the blowing pipe 12 blows air to the mold cavity in the opposite direction to help the mud cake separate from the compression female mold 72.
