Description

Technical Field

[0001] The invention relates to the technical field of sludge dehydration, and in particular to a sludge dehydration device and method for water conservancy project construction. Background Art

[0002] A large amount of sludge will remain after sewage treatment. Sludge dewatering is an important link in the treatment of domestic sewage and industrial wastewater. The volume and water content of the sludge after concentration and dehydration are greatly reduced, which not only achieves the "reduction" of pollution but also reduces the difficulty and cost of subsequent sludge disposal methods such as incineration or landfill. The main purpose of sludge treatment is to reduce the amount of sludge and stabilize it to facilitate the transportation and final disposal of sludge. On the one hand, sludge treatment can reduce the water content and change its fluid state to a solid state to achieve the purpose of reduction; on the other hand, it can stabilize organic matter, making it less likely to decompose and avoid secondary pollution to the environment. The method of sludge treatment often depends on the water content of the sludge and the final disposal method.

[0003] A Chinese patent discloses a sludge dewatering treatment device, the publication number is: CN117361835A, sovereignty. A sludge dewatering treatment device, including a support frame, characterized in that: a treatment outer cylinder is fixedly installed on the support frame, a dewatering mechanism is provided in the middle of the inner wall of the treatment outer cylinder, a squeezing mechanism used in conjunction with the dewatering mechanism is provided on one side of the inner wall of the treatment outer cylinder, an auxiliary mechanism is provided on the side of the treatment outer inner wall away from the squeezing mechanism, a discharge port is integrally formed on the side of the bottom of the treatment outer cylinder close to the dewatering mechanism, a mounting frame is fixedly installed on the outer side of the treatment outer cylinder, and the top of the mounting frame A sludge pump is fixedly installed, and a sewage inlet pipe is fixedly installed at the input end of the sludge pump. The sludge dewatering treatment device, by arranging a dewatering mechanism and using an extrusion mechanism, drives multiple dewatering inner cylinders to rotate at high speed in the treatment outer cylinder to perform centrifugal dewatering treatment on the sludge. At the same time, multiple push plates synchronously extrude and dehydrate the sludge in the corresponding dewatering inner cylinders, thereby improving the sludge dewatering treatment effect and solving the problem that traditional sludge dewatering treatment processes mostly use extrusion to dewater the sludge, the traditional sludge extrusion dewatering efficiency is low, and it is easy to cause the sieve holes to be blocked, and the sieve needs to be cleaned and replaced regularly.

[0004] According to the technical effects of the above-mentioned existing technologies and technical solutions, there are still areas that need to be optimized: when the sludge is sucked into the interior of the absorption tube, there will be lumps of sludge and more impurities. If they are not treated, the efficiency of sludge dehydration will be affected. After the sludge is dehydrated, it will still have certain fluid properties, and its disposal difficulty and cost are still high. The drying in this application can further reduce the residual moisture in the sludge, reduce transportation costs and subsequent processing difficulties. Summary of the invention

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Example 1 Reference Figures 1 to 11 , which is the first embodiment of the present invention, provides a sludge dewatering method for water conservancy project construction, which realizes efficient sludge dewatering.

[0038] The sludge is firstly absorbed, then the dewatering frame 301 is used to spin and remove water, and then the sludge is discharged and dried; First, the sucked sludge can be stirred and the lumps of sludge can be broken up by using the stirring mechanism 200, and then the sludge can be dehydrated by rotating the sludge by using the dehydration mechanism 300. After the dehydration is completed, the sludge can be dried by the drying mechanism 600 in cooperation with the turning component 604. When the sludge is sucked into the absorption tube 103, the initial structure of the sludge can be broken up by the setting of the stirring component 203, and the lumps of sludge can also be broken up. At the same time, the particulate impurities in the sludge can be filtered and collected by the setting of the filter plate 204i and the collection box 204h. The presence of impurities will affect the dehydration performance of the sludge. By filtering and removing impurities, the dehydration process of the sludge can be smoother, and the dehydration efficiency and degree of dehydration can be improved.

[0039] Example 2 Reference Figures 1 to 8 , which is the second embodiment of the present invention, provides a dewatering mechanism 300 to implement the sludge dewatering process.

[0040] The dehydration mechanism 300 includes a dehydration frame 301 disposed inside the dehydration box 100, and the dehydration frame 301 is provided with three groups, the inner side of the dehydration frame 301 is in contact with the outer side of the branch ring 106, the inner side of the dehydration frame 301 is provided with an extrusion ring 302, one side of the extrusion ring 302 is provided with a connecting rod 303, one side of the connecting rod 303 is provided with an electric cylinder 304, the right side of the electric cylinder 304 is provided on the inner wall of the dehydration box 100, the left side of the dehydration frame 301 is provided with a rotating assembly 305, and the surface of the rotating assembly 305 is provided with a feeding component 306; the rotating assembly 305 includes a cross bar 305a disposed on the inner wall of the dehydration box 100, and the surface of the cross bar 305a is provided with a fixing ring 305b, The inner wall of the dehydration frame 301 is provided with a toothed disc 305c, and the surface of the toothed disc 305c is meshed with a first gear 305d, and the inner wall of the first gear 305d is provided on the outer side of the dehydration frame 301, and a fixing piece 305e is provided on one side of the fixing ring 305b, and a third motor 305f is provided on one side of the fixing piece 305e, and a second gear 305g is provided on the output end of the third motor 305f, and the second gear 305g is meshed with the toothed disc 305c; the feeding component 306 includes a positioning ring 306a provided on the inner wall of the branch pipe 104, and a second spring 306b is provided on one side of the positioning ring 306a, and a sealing plate 306c is provided on one side of the second spring 306b, and the outer side of the sealing plate 306c contacts the inner side of the branch pipe 104.

[0041] Specifically, when the sludge enters the dewatering frame 301, centrifugal force is generated by high-speed rotation, so that the water in the sludge is thrown out, and then the squeezing of the squeezing ring 302 can greatly reduce the water content in the sludge.

[0042] Furthermore, when the sludge is dehydrated, the operation of the third motor 305f can drive the second gear 305g to rotate, and the rotation of the second gear 305g can drive the toothed disc 305c to rotate. When the toothed disc 305c rotates, it can engage and drive the first gear 305d to rotate, and the rotation of the first gear 305d can drive the dehydration frame 301 to rotate. When the dehydration frame 301 rotates at a high speed, the centrifugal force can be used to throw out the water in the sludge. After the water is thrown out, it will be divided into two parts. One part will be thrown into the inside of the guide plate 502 and then flow down, and the other part will directly fall into the inside of the rotating box 603f through the unloading plate 501 for storage. After the sludge is dehydrated, since the rotation of the dehydration frame 301 is at a high speed, the operation of the electric cylinder 304 drives the extrusion ring 302 to move on the inner wall of the dehydration frame 301, thereby squeezing the sludge and improving the dehydration efficiency.

[0043] Example 3 Reference Figures 2~11 , which is the third embodiment of the present invention, provides an air jet mechanism 400 to achieve anti-clogging treatment of the dewatering frame 301 after the sludge is dehydrated.

[0044] The jet mechanism 400 includes an air pump 401 disposed on the left side of the dehydration box 100, the jet end of the air pump 401 is connected to a jet pipe 402, one side of the jet pipe 402 is connected to the inside of the absorption tube 103, the inner wall of the absorption tube 103 is provided with a ventilation groove 403, the ventilation groove 403 extends from the inside of the branch pipe 104 to the inside of the jet ring 107; the outer side of the dehydration frame 301 is provided with a limiting ring 307, the outer side of the limiting ring 307 is provided with a limiting groove 308, the surface of the limiting groove 308 is rotatably connected to a limiting rod 309, and one side of the limiting rod 309 is provided on one side of the fixed ring 305b; the rotation Component 603 includes a moving hole 603a opened at the bottom of the dehydration box 100, and a moving rod 603b is arranged on the surface of the moving hole 603a. One side of the moving rod 603b is connected to the surface of the fixing ring 305b, and a tooth plate 603c is arranged on the right side of the moving rod 603b. The surface of the tooth plate 603c is meshed with a third gear 603d, and the bottom of the third gear 603d is rotatably connected to the top of the drying plate 601. A rotating column 603e is arranged on the top of the third gear 603d, and a rotating box 603f is arranged on the top of the rotating column 603e. The inner wall of the rotating box 603f is arranged with a partition plate 603g.

[0045] Specifically, when the dewatering frame 301 rotates or squeezes, the sludge will be squeezed onto the surface of the dewatering frame 301 to cause blockage. By setting the air pump 401, the dewatering frame 301 can be anti-blocked after the sludge is dehydrated to ensure the efficiency of the dewatering frame 301 in subsequent sludge dehydration.

[0046] Furthermore, after the sludge is squeezed, the squeezing ring 302 is reset and the first push rod 305h is started, so that the dehydration frame 301 can be driven to move to the left on the surface of the cross bar 305a. When the dehydration frame 301 moves to the left, the air pump 401 is started at the same time. By starting the air pump 401, the gas can be transmitted to the inside of the ventilation groove 403 through the jet pipe 402 and ejected from the outside of the jet ring 107. Due to the high-speed rotation and leftward movement of the dehydration frame 301, the jet can be used to The jet of the air ring 107 prevents the dewatering frame 301 from being blocked. Since the sludge no longer enters the dewatering frame 301, the squeezing plate 204b and the sealing plate 306c can be released from the squeezing pressure. When the squeezing plate 204b is released from the squeezing pressure, the sealing ring 204e can be opened, so that the impurities inside the sludge that are intercepted before the filter plate 204i fall into the collecting box 204h. After the sealing plate 306c is released from the squeezing pressure, it will be reset by the pulling force in the direction of the second spring 306b.

[0047] The remaining structure is the same as that of Example 2.

[0048] Example 4 Reference Figures 1 to 11 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: this embodiment provides a sludge dewatering device for water conservancy project construction.

[0049] When using the device; The operation of the absorption pump 102 can absorb the sludge into the absorption tube 103, and then the operation of the second motor 203a can use the stirring rod 203c to drive the stirring blade 203d to rotate. The rotation of the stirring blade 203d can break up the agglomerated substances in the sludge and the structure inside the sludge. When the sludge rises inside the absorption tube 103, it will squeeze the squeezing plate 204b. After the squeezing plate 204b is squeezed, it can rotate on the surface of the fixed rod 204a and squeeze the squeezing rod 204d. After the squeezing rod 204d is squeezed, the tension spring 204d can be pulled at the same time. -1 gives extrusion force to the sealing ring 204e, and after the sealing ring 204e is squeezed, it moves on the surface of the sealing groove 204f, so as to seal the connection between the absorption tube 103 and the collection box 204h. When the sludge flows through the filter plate 204i, it is guided by the guide ring 105 to flow into the inside of the branch pipe 104, so that the sludge can flow into the inside of the branch pipe 104 evenly under the action of the guide ring 105, and squeeze the sealing plate 306c inside the branch pipe 104, so that the sealing plate 306c moves to one side by the second spring 306b, and provides a path for the sludge to flow into the inside of the dehydration frame 301; When the sludge needs to be dehydrated, the operation of the third motor 305f can drive the second gear 305g to rotate, and the rotation of the second gear 305g can drive the toothed disc 305c to rotate, and when the toothed disc 305c rotates, it can mesh and drive the first gear 305d to rotate, and the rotation of the first gear 305d can drive the dehydration frame 301 to rotate. When the dehydration frame 301 rotates at a high speed, the water in the sludge can be thrown out by centrifugal force. After the water is thrown out, it will be divided into two parts, one part will be thrown into the inside of the guide plate 502 and then flow down, and the other part will directly fall into the inside of the rotating box 603f through the unloading plate 501 for storage. After the sludge is dehydrated, since the rotation of the dehydration frame 301 is high-speed, the operation of the electric cylinder 304 drives the extrusion ring 302 to move on the inner wall of the dehydration frame 301, thereby extruding the sludge and improving the dehydration efficiency; After the sludge is squeezed, the dehydration frame 301 can be driven to move to the left on the surface of the cross bar 305a by resetting the squeezing ring 302 and starting the first push rod 305h. When the dehydration frame 301 moves to the left, the air pump 401 is started at the same time. By starting the air pump 401, the gas can be transmitted to the inside of the ventilation groove 403 through the jet pipe 402 and sprayed out from the outside of the jet ring 107. Due to the high-speed rotation and leftward movement of the dehydration frame 301, an air jet hole is provided through the jet ring 107, so that each dehydration hole on the surface of the dehydration frame 301 can be cleaned by utilizing the high-speed rotation of the dehydration frame 301, so that the dehydration frame 301 can be prevented from being blocked; Since the sludge does not enter the interior of the dewatering frame 301, the squeezing force of the squeezing plate 204b and the sealing plate 306c can be released. When the squeezing force of the squeezing plate 204b is released, the sealing ring 204e can be opened, so that the impurities in the sludge that are intercepted in front of the filter plate 204i fall into the interior of the collecting box 204h. After the squeezing force is released, the sealing plate 306c is reset by the directional pulling force of the second spring 306b, so that when the dewatering frame 301 moves to the left, the branch ring 106 blocks the sludge, so that the sludge is pushed into the interior of the rotating box 603f, and when the dewatering frame 301 moves to the left, the moving rod 603b is used to drive the tooth plate 603c to move, and the movement of the tooth plate 603c drives the third gear 603d to rotate, and the rotation of the third gear 603d can drive the rotating box 603f to rotate; When the sludge falls into the rotating box 603f, the resetting of the dewatering frame 301 can drive the rotating box 603f to rotate again. Through the coordinated use of the second push rod 604a, the third push rod 604b and the fourth motor 604c, the turning blades 604e can be driven to turn the sludge inside the rotating box 603f, and the dryer 602 can be used again to enhance the drying efficiency.

[0050] In summary: when the sludge is sucked into the absorption tube 103, the initial structure of the sludge can be broken up by the setting of the stirring component 203, and the lumped sludge can also be broken up. At the same time, through the setting of the filter plate 204i and the collection box 204h, the particulate impurities in the sludge can be filtered and collected. The presence of impurities will affect the dehydration performance of the sludge. By filtering and removing impurities, the dehydration process of the sludge can be smoother, and the dehydration efficiency and degree of dehydration can be improved.
