Description

Technical Field

[0001] This utility model relates to the field of sludge processing technology, specifically to an integrated equipment for sludge dewatering and drying in sedimentation tanks. Background Technology

[0002] With the acceleration of urbanization and the improvement of industrialization, the number of sewage treatment plants is constantly increasing, and the amount of sludge produced is also rising sharply. Sludge contains a large amount of water and harmful substances, such as heavy metals and pathogens. The main goals of sludge treatment include reducing volume, lowering water content, stabilization, harmlessness, and resource utilization.

[0003] A search revealed a utility model patent with Chinese patent publication number CN216427055U, which discloses an integrated dewatering device for sludge from a waterworks. The device includes a dewatering tank, with fixed grooves on the lower left and right walls of the tank. A dewatering mechanism is slidably connected between the two fixed grooves. A feed hopper is fixedly connected to the upper left wall of the tank, and a squeezing mechanism is movably connected to the middle of the upper end of the tank.

[0004] The above-mentioned device dewaters sludge through a dewatering frame and a squeezing plate. After the filtration is completed, the dewatering frame needs to be removed to dump the sludge, which is inconvenient and takes a long time, and there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide an integrated equipment for sludge dewatering and drying in sedimentation tanks, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated sludge dewatering and drying device for sedimentation tanks, comprising a mounting frame, a dewatering component installed inside the mounting frame, the dewatering component including a dewatering frame fixedly connected inside the mounting frame, a plurality of equally spaced through holes being opened on the bottom inner wall of the dewatering frame, a blocking frame being slidably inserted inside the dewatering frame, the blocking frame and the dewatering frame forming a complete space, a filter cloth being placed on the bottom inner wall of the dewatering frame, the filter cloth covering the top of the plurality of through holes, a fixing ring being placed on the top of the filter cloth, the fixing ring being fixedly connected to the dewatering frame by bolts, and a hydraulic cylinder being fixedly installed on one outer wall of the dewatering frame, the output end of the hydraulic cylinder being fixedly connected to the blocking frame.

[0007] As a further preferred embodiment of this technical solution, a hydraulic cylinder two is fixedly installed on the top outer wall of the mounting frame, and a horizontally arranged pressure plate is fixedly connected to the output end of the hydraulic cylinder two. The pressure plate is adapted to the internal space of the dehydration frame, and an electric heating wire one is provided inside the pressure plate.

[0008] The device can be quickly put into use after the sludge is dewatered and discharged, without the need for extra operations, which helps to improve the working efficiency of the device. The sludge enters the space formed by the dewatering frame and the blocking frame through the opening on the side of the mounting frame. Because the edge of the filter cloth is fixed to the bottom of the dewatering frame by the fixing ring with bolts, the filtrate will not pass through the part pressed by the fixing ring. Instead, it will pass through the filter cloth pores and fall from the through hole at the bottom of the dewatering frame. When the filtration efficiency decreases, the second hydraulic cylinder at the top of the mounting frame is activated. The pressure plate is driven into the dewatering frame by the second hydraulic cylinder. Under the action of pressure, the filtration speed is faster, and then the forming is completed. Then, the first electric heating wire inside the pressure plate is activated to speed up this process. Then, the first hydraulic cylinder is activated to move the blocking frame towards the collection hopper. The sludge on the top of the filter cloth is pushed into the collection hopper by the blocking frame.

[0009] As a further preferred embodiment of this technical solution, a collection hopper is fixedly installed on one side of the outer wall of the mounting frame, and an inclined screw conveyor is installed inside the collection hopper. The screw conveyor has a feed inlet at its bottom, and the collection hopper extends from one end of the top of the screw conveyor, with a discharge outlet at the top of the screw conveyor.

[0010] As a further preferred embodiment of this technical solution, a drying component is installed inside the mounting frame. The drying component includes a drying cylinder fixedly installed on one side of the bottom inner wall of the mounting frame via a support frame. A heat insulation cover is provided on the outside of the drying cylinder, and an electric heating wire is provided inside the heat insulation cover. The discharge port of the screw conveyor is located at the top of the drying cylinder. A baffle is slidably inserted into one side of the outer wall of the mounting frame, and the baffle completely closes the bottom opening of the drying cylinder.

[0011] As a further preferred embodiment of this technical solution, a horizontally arranged extension plate is fixedly connected inside the drying cylinder, a protective cover is installed on the top outer wall of the extension plate, a motor is installed inside the protective cover, and an auger is coaxially fixed to the output end of the motor, the auger extending into the internal space of the drying cylinder.

[0012] Turn on the second heating wire outside the drying cylinder. Heat is transferred to the clay blocks through the drying cylinder, and drying can begin. At the same time, start the motor inside the protective cover. The motor output drives the auger to rotate. The rotation of the auger causes the clay blocks to be transported upward and tumbled. Then, they fall from the gaps around the auger back to the bottom and begin to circulate, so that the clay blocks are heated evenly enough.

[0013] As a further preferred embodiment of this technical solution, the auger rotating shaft is equipped with a scraper, which is in contact with the inner circumferential wall of the drying cylinder.

[0014] As a further preferred embodiment of this technical solution, a mud scraper is provided at the bottom of the inner wall on one side of the blocking frame.

[0015] This utility model provides an integrated device for sludge dewatering and drying in sedimentation tanks, which has the following beneficial effects:

[0016] (1) By setting up a dewatering component, this utility model can quickly discharge the sludge after dewatering, and the device can be put into use quickly without any extra operations, which is conducive to improving the working efficiency of the device. The sludge enters the space composed of the dewatering frame and the blocking frame through the opening on the side of the mounting frame. Because the edge of the filter cloth is fixed to the bottom of the dewatering frame by bolts with the fixing ring, the filtrate will not pass through the part pressed by the fixing ring. It will pass through the filter cloth filter holes and fall from the through hole at the bottom of the dewatering frame. When the filtration efficiency decreases, the hydraulic cylinder two above the mounting frame is activated. The pressure plate is driven into the dewatering frame by the hydraulic cylinder two. Under the action of pressure, the filtration speed is faster and then the forming is completed. Then, the electric heating wire one inside the pressure plate is activated to speed up this process. Then, the hydraulic cylinder one is activated to drive the blocking frame to move towards the collection hopper. The mud on the top of the filter cloth is pushed into the collection hopper by the blocking frame.

[0017] (2) By setting up a drying component, the second electric heating wire outside the drying cylinder is activated, and the heat is transferred to the mud block through the drying cylinder, and the drying can begin. At the same time, the motor inside the protective cover is activated, and the motor output drives the auger to rotate. The rotation of the auger causes the mud block to be transported upward and tumbled, and then falls from the gap around the auger back to the bottom and starts to circulate, so that the mud block is heated evenly enough.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 and Figure 3 As shown in this embodiment, an integrated sludge dewatering and drying device for sedimentation tanks includes a mounting frame 1. A dewatering component 4 is installed inside the mounting frame 1. The dewatering component 4 includes a dewatering frame 401 fixedly connected inside the mounting frame 1. Several through holes are evenly distributed on the bottom inner wall of the dewatering frame 401. A blocking frame 402 is slidably inserted inside the dewatering frame 401. The blocking frame 402 and the dewatering frame 401 form a complete space. A filter cloth 403 is placed on the bottom inner wall of the dewatering frame 401. The filter cloth 403 covers the top of the several through holes. A fixing ring 404 is placed on the top of the filter cloth 403. The fixing ring 404 is fixedly connected to the dewatering frame 401 by bolts. A hydraulic cylinder 405 is fixedly installed on one side outer wall of the dewatering frame 401. The output end of the hydraulic cylinder 405 is fixedly connected to the blocking frame 402.

[0025] A hydraulic cylinder 406 is fixedly installed on the top outer wall of the mounting frame 1. A horizontally arranged pressure plate 407 is fixedly connected to the output end of the hydraulic cylinder 406. The pressure plate 407 is adapted to the internal space of the dehydration frame 401, and an electric heating wire is installed inside the pressure plate 407.

[0026] The sludge enters the space formed by the dewatering frame 401 and the blocking frame 402 through the opening on the side of the mounting frame 1. Because the edge of the filter cloth 403 is fixed to the bottom of the dewatering frame 401 by bolts with the fixing ring 404, the filtrate will not pass through the part pressed by the fixing ring 404. Instead, it will pass through the filter holes of the filter cloth 403 and fall through the through hole at the bottom of the dewatering frame 401. When the filtration efficiency decreases, the second hydraulic cylinder 406 above the mounting frame 1 is activated. The pressure plate 407 is driven into the dewatering frame 401 by the second hydraulic cylinder 406. Under pressure, the filtration speed is faster, and the forming is completed. Then, the first electric heating wire inside the pressure plate 407 is activated to speed up this process. Then, the first hydraulic cylinder 405 is activated to move the blocking frame 402 toward the collection hopper 2. The sludge on the top of the filter cloth 403 is pushed into the collection hopper 2 by the blocking frame 402.

[0027] like Figure 1 and Figure 2 As shown, a collection hopper 2 is fixedly installed on one side of the outer wall of the mounting frame 1. An inclined screw conveyor 3 is installed inside the collection hopper 2. A feed inlet is opened at the bottom of the screw conveyor 3, and the top end of the screw conveyor 3 extends out of the collection hopper 2. A discharge outlet is opened at the top of the screw conveyor 3.

[0028] Start the screw conveyor 3 inside the collection hopper 2. The mud lumps are scraped by the screw rod inside the screw conveyor 3 to form small pieces, which helps to improve the subsequent drying efficiency.

[0029] like Figure 2 and Figure 4 As shown, a drying component 5 is installed inside the mounting frame 1. The drying component 5 includes a drying cylinder 501 fixedly installed on one side of the bottom inner wall of the mounting frame 1 by a support frame. A heat insulation cover is provided on the outside of the drying cylinder 501, and an electric heating wire is provided inside the heat insulation cover. The discharge port of the screw conveyor 3 is located at the top of the drying cylinder 501. A baffle 502 is slidably inserted into one side of the outer wall of the mounting frame 1, and the baffle 502 completely closes the bottom opening of the drying cylinder 501.

[0030] A horizontally arranged extension plate 503 is fixedly connected inside the drying cylinder 501. A protective cover 504 is installed on the top outer wall of the extension plate 503. A motor is installed inside the protective cover 504, and an auger 505 is coaxially fixed to the output end of the motor. The auger 505 extends into the internal space of the drying cylinder 501.

[0031] The second heating wire outside the drying cylinder 501 is activated, and heat is transferred to the clay block through the drying cylinder 501 to begin drying. At the same time, the motor inside the protective cover 504 is activated, and the motor output drives the auger 505 to rotate. The rotation of the auger 505 causes the clay block to be conveyed upward and tumbled, and then falls from the gaps around the auger back to the bottom, starting a cycle that ensures the clay block is heated evenly.

[0032] like Figure 4 As shown, a scraper 506 is installed on the rotating shaft of the auger 505. The scraper 506 is in contact with the inner circumference of the drying cylinder 501. The scraper 506 can continuously scrape the inner wall of the drying cylinder 501, effectively preventing the excessive thickness of the deposits on the inner wall of the drying cylinder 501 from affecting heat transfer.

[0033] like Figure 3 As shown, a mud scraper 408 is provided at the bottom of the inner wall of one side of the blocking frame 402, which can increase the mud scraping effect of the blocking frame 402.

[0034] This utility model provides an integrated device for sludge dewatering and drying in sedimentation tanks, the specific working principle of which is as follows:

[0035] When the device is working, sludge enters the space formed by the dewatering frame 401 and the blocking frame 402 through the opening on the side of the mounting frame 1. Because the edge of the filter cloth 403 is fixed to the bottom of the dewatering frame 401 by bolts with the fixing ring 404, the filtrate will not pass through the part compressed by the fixing ring 404. Instead, it will pass through the filter holes of the filter cloth 403 and fall through the through hole at the bottom of the dewatering frame 401. When the filtration efficiency decreases, the second hydraulic cylinder 406 above the mounting frame 1 is activated. The pressure plate 407 is driven into the dewatering frame 401 by the second hydraulic cylinder 406. Under pressure, the filtration speed is increased, and the forming is completed. Then, the first electric heating wire inside the pressure plate 407 is activated to speed up this process. Then, the first hydraulic cylinder 405 is activated to move the blocking frame 402 toward the collection hopper 2. The top of the filter cloth 403... The mud lumps are pushed quickly into the collection hopper 2 by the blocking frame 402. Then, the screw conveyor 3 inside the collection hopper 2 is started. The mud lumps are scraped by the screw rod inside the screw conveyor 3 to form small pieces, which then enter the drying cylinder 501 through the opening at the top. Then, the electric heating wire 2 outside the drying cylinder 501 is started. Heat is transferred to the mud lumps through the drying cylinder 501, and drying can begin. At the same time, the motor inside the protective cover 504 is started. The output end of the motor drives the auger 505 to rotate. The rotation of the auger 505 causes the mud lumps to be conveyed upward and tumbled. Then, they fall from the gaps around the auger and return to the bottom, starting the cycle. This ensures that the mud lumps are heated evenly. The scraper 506 can continuously scrape the inner wall of the drying cylinder 501, effectively preventing the inner wall of the drying cylinder 501 from being too thick and affecting the heat transfer.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
