A production device and production process for sludge treatment and reuse

Abstract

The present invention discloses a production device and a production process for sludge treatment and reuse, belonging to the technical field of sludge treatment. The production device for sludge treatment and reuse includes a mounting frame. A filtering mechanism for filtering sludge is arranged on the surface of the water outlet hole. A feeding mechanism for feeding sludge is arranged inside the mounting frame at the position of the feeding bin. The sludge is dehydrated by the centrifugal force generated by driving the cylinder to rotate at a high speed through a rotating mechanism. When the filter cylinder drives the drain pipe to rotate, the limiting plate pushes the piston to slide inside the drain pipe through a push rod, and pushes the limiting block to close the drain port. At this time, the piston squeezes the air inside the drain pipe, so that the air blows towards the inside of the filter cylinder through the filter net, causing the sludge adhering to the surface of the filter net to fall on the surface of the filter net. The sludge enters the inside of the prefabricated groove. Through the synchronous rotation of the prefabricated roller and the pressing roller, the pressing block compacts the sludge into a block shape, preventing the dehydrated sludge from floating in the air.

Description

Technical Field

[0001] The present invention relates to the technical field of sludge treatment, and particularly to a production device and production process for sludge treatment and reuse. Background Art

[0002] The utilization of sludge in building materials is a new way to treat industrial sludge at present. On the one hand, this way can reduce the environmental pollution caused by sludge, and on the other hand, it also promotes the reuse of resources. There are relatively many siliceous and aluminous inorganic substances and some other organic substances in sludge, which are similar to the material composition of clay raw materials in some building materials. There are many current ways of sludge building material utilization, including using dried sludge, some ash residues after sludge incineration, and directly using dewatered sludge and other methods to complete. In these methods, if dried sludge is used, it will increase the processing economic cost, and generally this method will only be regarded as an alternative means for sludge disposal, while most will choose the method of directly using dewatered sludge.

[0003] In recent years, sewage treatment plants have found that dewatered sludge can be used as a raw material for brick and tile production, and gradually explored a new utilization method. After a series of processing, the dewatered sludge becomes a substance similar to clay and can be made into various ceramic products, including excellent-quality bricks, floor tiles, etc. However, the high water content and complex composition of sludge not only limit the utilization of sludge in the brick and tile industry, but also bring many difficulties in treatment technology. Only about 10% of sludge can be admixed by traditional methods, and the utilization rate is extremely low.

[0004] Chinese Patent CN116675411B announced on November 07, 2023, discloses a sludge dewatering environmental protection device. Through the set control mechanism, multiple filter plates can be opened and closed to effectively discharge sludge, and at the same time, it is also convenient to clean the filter plates themselves. At the same time, in cooperation with the circulation mechanism, the purpose of secondary dewatering of the filtered sludge is achieved, and the whole operation process is fast and worthy of popularization and use. However, when the filter plates of this sludge dewatering environmental protection device squeeze the sludge, due to the certain viscosity of the sludge, the sludge is likely to block the dewatering holes on the surface of the filter plates, making the filter plates unable to be used normally.

The sludge enters the interior of the prefabricated trough, and the pressing block compacts the sludge into blocks through the synchronous rotation of the prefabricated roller and the pressing roller to prevent the dehydrated sludge from floating in the air.

Detailed implementation mode

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments may be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0031] Example 1, please refer to Figures 1-9, the present invention provides a technical solution: a production device for sludge treatment and reuse, including a mounting frame 1, a dehydration tank 2 installed on the top of the mounting frame 1, and a filter cylinder 3 rotatably connected inside the dehydration tank 2. A conveyor belt 11 is installed at the bottom of the mounting frame 1. The dehydration tank 2 includes a tank body 21, a feed inlet 22 provided at the top of the tank body 21, and a water outlet 23 provided on the side wall of the tank body 21. The filter cylinder 3 includes a cylinder body 31 rotatably connected inside the tank body 21, water outlet holes 32 uniformly arranged on the outer peripheral surface of the cylinder body 31 along the circumferential direction, and a blanking port 33 provided at the central position of the bottom of the cylinder body 31. A rotating mechanism 4 for stirring the sludge inside the cylinder body 31 is provided inside the tank body 21. The rotating mechanism 4 includes a scraping component for scraping the sludge on the inner wall of the cylinder body 31 and a crushing component for crushing the sludge; a filtering mechanism 5 for filtering the sludge is provided on the surface of the water outlet holes 32. An electric valve 6 adapted to the blanking port 33 is provided on the bottom surface of the tank body 21. A blanking bin 7 is formed in the interior of the mounting frame 1 in a hollow manner. A double-screw conveyor 8 is installed inside the blanking bin 7. A discharge port 9 adapted to the blanking bin 7 is provided inside the mounting frame 1. A blanking mechanism 10 for feeding the sludge is provided at the position of the blanking bin 7 inside the mounting frame 1.

[0032] During use, first, the sludge is injected into the interior of the cylinder body 31 through the feed inlet 22. Then, the external power supply is connected to start the rotating mechanism 4 to drive the filter cylinder 3 to rotate at a high speed and generate a centrifugal force, so that the sludge is dispersed around inside the filter cylinder 3. Under the action of the centrifugal force, the water in the sludge is filtered through the filtering mechanism and discharged from the water outlet holes 32, and flows into the interlayer between the tank body 21 and the cylinder body 31, and then is discharged from the dehydration tank 2 through the water outlet 23, so that the water in the sludge can be separated. During the above process, the filtering mechanism 5 can scrape off the sludge adhering to the inner wall of the cylinder body 31, and the crushing component can crush the large pieces of sludge, which can improve the dehydration efficiency of the sludge. When the water in the sludge is completely separated, the electric valve 6 is opened to enable the dehydrated sludge to enter the blanking bin 7 inside the mounting frame 1 through the blanking port 33. Then, the double-screw conveyor 8 is started to crush the sludge again and convey it to the surface of the blanking mechanism 10 through the discharge port 9, so that the blanking mechanism 10 presses the sludge into blocks and drops onto the surface of the conveyor belt 11, and conveys it to the next process.

[0033] To prevent the sludge from adhering to the inner wall of the filter cylinder 3 when the filter cylinder 3 rotates, thereby affecting the dehydration efficiency of the sludge, please refer to Figures 2-4, as shown in the figure, the scraping assembly includes a servo motor 401 and a rotating sleeve 402 that drives the rotation of the cylinder body 31. A first gear 403 is fixedly connected to the position of the rotating sleeve 402 close to the inner wall of the top of the tank body 21. A second gear 404 adapted to the first gear 403 is provided on the inner wall of the top of the tank body 21. A connecting shell 405 is rotatably connected to the outer wall of the rotating sleeve 402. An internal gear ring 406 adapted to the second gear 404 is provided on the inner wall of the connecting shell 405. A first scraping plate 407 that closely adheres to the inner wall of the cylinder body 31 is fixedly connected to the outer wall of the connecting shell 405. A feeding plate 408 for feeding the sludge is fixedly connected to one side of the first scraping plate 407 close to the bottom direction of the cylinder body 31, and one end of the feeding plate 408 is rotatably connected to the rotating sleeve 402.

[0034] During use, connect to an external power supply to start the servo motor 401 and drive the cylinder body 31 to rotate through the rotating sleeve 402. At the same time, when the rotating sleeve 402 rotates, it will drive the first gear 403 to rotate. Through the mutual meshing between the first gear 403, the second gear 404, and the internal gear ring 406, when the first gear 403 rotates, it can drive the internal gear ring 406 to rotate in the direction opposite to the internal gear ring 406 through the second gear 404, thereby pushing the connecting shell 405 and the first scraping plate 407 to rotate, so that the first scraping plate 407 can scrape the sludge on the inner wall surface of the cylinder body 31. The scraped sludge will splash towards the center direction of the cylinder body 31 along the surface of the first scraping plate 407. After the sludge is dehydrated by the centrifugal force generated by the high-speed rotation of the cylinder body 31, the servo motor 401 drives the rotating sleeve 402 to rotate slowly, so that the first scraping plate 407 scrapes off the sludge adhering to the inner wall surface of the cylinder body 31 and then drops into the inside of the cylinder body 31. At the same time, the first scraping plate 407 will drive the feeding plate 408 to rotate, thereby scraping the sludge towards the feeding port 33 and entering the inside of the feeding bin 7 through the electric valve 6.

[0035] To prevent large pieces of sludge from affecting the dehydration efficiency, please refer to Figure 5 , as shown in the figure, the crushing assembly includes a connecting column 409 rotatably connected to the inner wall of the rotating sleeve 402, and the bottom end of the connecting column 409 is fixedly connected to the inner wall of the cylinder body 31. A plurality of groups of first bevel gears 410 are axially arranged on the outer wall of the connecting column 409. A connecting rod 411 is rotatably connected to the outer wall of the rotating sleeve 402, and one end of the connecting rod 411 extends into the inside of the rotating sleeve 402. A second bevel gear 412 adapted to the first bevel gear 410 is provided at the end of the connecting rod 411 extending into the inside of the rotating sleeve 402. A plurality of groups of crushing blades 413 are axially arranged on the outer wall of the connecting rod 411.

[0036] During use, through the fixed connection between the connecting column 409 and the cylinder body 31, when the rotating sleeve 402 rotates, the connecting column 409 remains stationary, and when the rotating sleeve 402 rotates, it drives the connecting rod 411 to rotate. Through the meshing between the first bevel gear 410 and the second bevel gear 412, when the rotating sleeve 402 drives the connecting rod 411 to rotate, the connecting rod 411 itself also rotates, causing the crushing blades 413 on the surface of the connecting rod 411 to rotate at high speed, thereby being able to break up large pieces of sludge near the surface of the crushing blades 413, and thus preventing the large pieces of sludge from affecting the dehydration efficiency of the device.

[0037] To prevent sludge from passing through the water outlet holes 32, please refer to Figure 9 , as shown in the figure, the filtering mechanism 5 includes a drain pipe 501 installed inside the water outlet holes 32. A filter net 502 adapted to the water outlet holes 32 is arranged on one side of the drain pipe 501 close to the water outlet holes 32, and a drain port 503 is arranged on one side of the drain pipe 501 close to the outer wall of the cylinder body 31.

[0038] During use, the sewage will enter the inside of the drain pipe 501 through the water outlet holes 32. At this time, due to the setting of the filter net 502, it can prevent sludge from entering the inside of the drain pipe 501. Due to the setting that one end of the drain pipe 501 close to the water outlet holes 32 is high and the end far from the water outlet holes 32 is low, the sewage entering the inside of the drain pipe 501 will flow downward along the drain pipe 501 and flow into the interlayer between the body 21 and the cylinder body 31 through the drain port 503.

[0039] To prevent sludge from clogging the filter holes on the surface of the filter net 502, please refer to Figure 3 and Figure 9 , as shown in the figure, the filtering mechanism 5 further includes a limiting block 504 arranged on the surface of the drain port 503 and adapted to the drain port 503. A spring piece 505 adapted to the limiting block 504 is arranged on the surface of the drain pipe 501. A connecting spring 506 is fixedly connected inside the drain pipe 501. A push rod 507 is fixedly connected to one side of the connecting spring 506 far from the drain port 503. A piston 508 adapted to the drain pipe 501 is arranged on one side of the push rod 507 close to the drain port 503. A limiting plate 509 adapted to the push rod 507 is arranged on the inner wall of the tank body 21.

[0040] During use, the filter cartridge 3 drives the drain pipe 501 to rotate. When the drain pipe 501 and the limit plate 509 are on the same horizontal line, the limit plate 509 will squeeze the push rod 507, thereby pushing the push rod 507 to slide into the interior of the drain pipe 501 and squeezing the connecting spring 506, so that the push rod 507 pushes the piston 508 to slide inside the drain pipe 501. When the piston 508 slides, it will push the limit block 504 to rotate and squeeze the spring piece 505, so that the limit block 504 closes the drain port 503. At this time, the piston 508 continues to slide inside the drain pipe 501 and squeezes the air inside the drain pipe 501, so that the air blows through the filter screen 502 into the interior of the filter cartridge 3. During this process, the sludge adhering to the surface of the filter screen 502 can be backwashed by the gas. After the push rod 507 is separated from the limit plate 509, the connecting spring 506 will push the push rod 507 to reset, so that the piston 508 generates a suction force through the drain pipe 501 and sucks the sewage inside the filter cartridge 3 into the interior of the drain pipe 501, improving the dehydration efficiency of the sludge.

[0041] Please refer to Figure 7 , as shown in the figure, the blanking mechanism 10 includes a material storage tank 1001 and a molding assembly. A material storage tank 1001 adapted to the discharge port 9 is provided inside the mounting frame 1. An electric slide rail 1002 is fixedly connected to the inner wall of the material storage tank 1001. An electric slider 1003 is slidably connected to the surface of the electric slide rail 1002. A second scraper 1004 is fixedly connected to the surface of the electric slider 1003.

[0042] During use, after the crushed sludge enters the interior of the material storage tank 1001 through the discharge port 9, the sludge will accumulate directly below the discharge port 9. At this time, by sliding the electric slider 1003 on the surface of the electric slide rail 1002, the second scraper 1004 reciprocally scrapes on the surface of the material storage tank 1001, so that the sludge can be evenly filled in the interior of the material storage tank 1001.

[0043] In order to prevent the dehydrated sludge from floating in the air, please refer to Figures 7-8, As shown in the figure, the molding assembly includes a driving motor 1005 arranged on the outer wall of the mounting frame 1. A connecting shaft 1006 adapted to the driving motor 1005 is arranged inside the mounting frame 1. A pressure roller 1007 is fixedly connected to the outer wall of the connecting shaft 1006. A plurality of pressure blocks 1008 are arranged on the outer peripheral surface of the pressure roller 1007 along the circumferential direction. A connecting gear 1009 is fixedly connected to the outer wall of one end of the connecting shaft 1006. A rotating column 1010 is rotatably connected inside the mounting frame 1. A linkage gear 1011 adapted to the connecting gear 1009 is arranged on the outer wall of one end of the rotating column 1010. A prefabricating roller 1012 is fixedly connected to the outer wall of the rotating column 1010. A prefabricating groove 1013 adapted to the pressure block 1008 is arranged on the outer peripheral surface of the prefabricating roller 1012 along the circumferential direction. A return spring 1014 is fixedly connected to the inner wall of the prefabricating roller 1012. A push plate 1015 adapted to the prefabricating groove 1013 is arranged in the direction close to one side of the prefabricating groove 1013 of the return spring 1014. A blanking groove 1016 adapted to the prefabricating groove 1013 is arranged on the mounting frame 1 in the direction close to the conveyor belt 11.

[0044] During use, the sludge in the storage tank 1001 will enter the inside of the prefabricating groove 1013 on the surface of the prefabricating roller 1012. Then, connect to an external power supply to start the driving motor 1005, which drives the pressure roller 1007 to rotate through the connecting shaft 1006. At the same time, through the meshing of the connecting gear 1009 and the linkage gear 1011, when the connecting shaft 1006 drives the connecting gear 1009 to rotate, it will drive the rotating column 1010 to rotate synchronously through the linkage gear 1011, so that the prefabricating roller 1012 and the pressure roller 1007 rotate synchronously. When the pressure roller 1007 and the prefabricating roller 1012 rotate, the pressure block 1008 will close with the prefabricating groove 1013, so that the pressure block 1008 presses the sludge inside the prefabricating groove 1013, compresses it into a block and squeezes the return spring 1014. When the sludge block moves to directly above the blanking groove 1016 along with the rotation of the prefabricating roller 1012, the return spring 1014 pushes the push plate 1015 to slide inside the prefabricating groove 1013, pushes the sludge block into the inside of the blanking groove 1016 and drops it onto the surface of the conveyor belt 11.

[0045] The present invention also provides a production process embodiment of a production device for sludge treatment and reuse:

[0046] S1: Feeding. First, inject sludge into the inside of the cylinder body 31 through the feed inlet 22;

[0047] S2: Dewatering. Start the rotating mechanism 4 so that the servo motor 401 drives the cylinder body 31 to rotate at a high speed through the rotating sleeve 402. At the same time, the first scraper 407 can scrape off the sludge adhering to the inner wall of the cylinder body 31, and the crushing blades 413 can crush large pieces of sludge, and use the centrifugal force generated by the rotation of the cylinder body 31 to dewater the sludge;

[0048] S3: Drainage. The sludge and sewage can be separated through the filter screen 502 to prevent the sludge from being discharged from the inside of the cylinder body 31 through the water outlet hole 32. After the sewage enters the interlayer between the tank body 21 and the cylinder body 31 through the filter screen 502, it is discharged through the water outlet 23.

[0049] S4: Feeding. After the sludge dewatering is completed, it is crushed by the double-screw conveyor 8 and then conveyed to the inside of the storage tank 1001. Through the cooperation of the pressure roller 1007 and the prefabrication roller 1012, the sludge is pressed into blocks. Then the blocky sludge falls onto the surface of the conveyor belt 11 and is conveyed to the drying chamber.

[0050] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
