Description

Technical Field

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

[0002] The use of sludge as building materials is a new way of treating industrial sludge. On the one hand, this method can reduce the environmental pollution caused by sludge, and on the other hand, it also promotes the recycling of resources. Sludge contains a large amount of silicon-aluminum inorganic matter and some other organic matter, which is similar to the material composition of clay raw materials in some building materials. There are many ways to use sludge as building materials, including the use of dried sludge, some ash after sludge incineration, and direct use of dehydrated sludge. Among these methods, if dried sludge is used, the economic cost of processing will increase. Generally, this method will only be used as an alternative means of sludge disposal, and most people will choose to directly use dehydrated sludge.

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

[0004] Chinese patent CN116675411B announced on November 7, 2023 discloses a sludge dewatering environmental protection device. Through the control mechanism set up, multiple filter press plates can be opened and closed to achieve effective discharge of sludge, and it is also convenient to clean the filter press plates themselves. At the same time, it cooperates with the circulation mechanism to achieve the purpose of secondary dewatering of the sludge after filtration. The whole operation process is fast and worthy of popularization and use. However, in this sludge dewatering environmental protection device, when the filter press plate squeezes the sludge, due to the certain viscosity of the sludge, the sludge can easily clog the dehydration holes on the surface of the filter press plate, making the filter press plate unable to be used normally.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0018] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Example

[0019] See also Figure 1-Figure 9The present invention provides a technical solution: a production device for sludge treatment and reuse, comprising a mounting frame 1, a dewatering tank 2 mounted on the top of the mounting frame 1 and a filter cartridge 3 rotatably connected to the inside of the dewatering tank 2, a conveyor belt 11 is installed at the bottom of the mounting frame 1, the dewatering tank 2 comprises a tank body 21, a feed inlet 22 arranged at the top of the tank body 21 and a water outlet 23 arranged on the side wall of the tank body 21, the filter cartridge 3 comprises a cylinder body 31 rotatably connected to the inside of 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 feed outlet 33 arranged at the central position of the bottom of the cylinder body 31, and the inside of the tank body 21 is provided with a filter cartridge 33. A rotating mechanism 4 is provided for stirring the sludge inside the cylinder 31, and the rotating mechanism 4 includes a scraping component for scraping the sludge on the inner wall of the cylinder 31, and a crushing component for crushing the sludge; a filtering mechanism 5 is provided on the surface of the water outlet 32 ​​for filtering the sludge, an electric valve 6 adapted to the discharge port 33 is provided on the bottom surface of the tank body 21, a discharge bin 7 is formed in the hollow interior of the mounting frame 1, a double screw conveyor 8 is installed inside the discharge bin 7, a discharge port 9 adapted to the discharge bin 7 is provided inside the mounting frame 1, and a discharge mechanism 10 for discharging the sludge is provided at the discharge bin 7 inside the mounting frame 1.

[0020] When in use, first inject the sludge into the cylinder 31 through the feed port 22, then connect the external power supply to start the rotating mechanism 4 to drive the filter cylinder 3 to rotate at high speed and generate centrifugal force, so that the sludge is dispersed around the inside of the filter cylinder 3. Under the action of centrifugal force, the water in the sludge is filtered by the filtering mechanism and discharged from the water outlet 32, and flows into the interlayer between the tank body 21 and the cylinder 31, and then discharged into the dehydration tank 2 through the water outlet 23, so that the water in the sludge can be separated. In the above process, the filtering mechanism 5 can The sludge adhering to the inner wall of the cylinder 31 is scraped off, 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 separated, the electric valve 6 is opened to allow the dehydrated sludge to enter the discharge bin 7 inside the mounting frame 1 through the discharge port 33, and then the double screw conveyor 8 is started to crush the sludge again and convey it to the surface of the discharge mechanism 10 through the discharge port 9, so that the discharge mechanism 10 presses the sludge into blocks and drops it onto the surface of the conveyor belt 11, and then conveys it to the next process.

[0021] In order to prevent the sludge from adhering to the inner wall of the filter cartridge 3 when the filter cartridge 3 rotates, thereby affecting the dewatering efficiency of the sludge, please refer to Figure 2-Figure 4As shown in the figure, the scraping assembly includes a servo motor 401, and a rotating sleeve 402 for driving the cylinder 31 to rotate, the rotating sleeve 402 is fixedly connected with a first gear 403 at a position close to the top inner wall of the tank body 21, and a second gear 404 adapted to the first gear 403 is provided on the top inner wall of the tank body 21, a connecting shell 405 is rotatably connected to the outer wall of the rotating sleeve 402, an inner gear ring 406 adapted to the second gear 404 is provided on the inner wall of the connecting shell 405, a first scraper 407 tightly attached to the inner wall of the cylinder 31 is fixedly connected to the outer wall of the connecting shell 405, a discharge plate 408 for discharging sludge is fixedly connected to one side of the first scraper 407 close to the bottom direction of the cylinder 31, and one end of the discharge plate 408 is rotatably connected to the rotating sleeve 402.

[0022] When in use, connect the external power supply to start the servo motor 401 and drive the cylinder 31 to rotate through the rotating sleeve 402. At the same time, the rotating sleeve 402 will drive the first gear 403 to rotate when rotating. Through the mutual meshing between the first gear 403, the second gear 404 and the inner gear ring 406, the first gear 403 can drive the inner gear ring 406 to rotate in the opposite direction of the inner gear ring 406 through the second gear 404, thereby pushing the connecting shell 405 and the first scraper 407 to rotate, so that the first scraper 407 can scrape the cylinder 3 1, and the scraped sludge will splash toward the center direction of the cylinder 31 along the surface of the first scraper 407. After the sludge is dehydrated by the centrifugal force generated by the high-speed rotation of the cylinder 31, the servo motor 401 drives the rotating sleeve 402 to rotate slowly, so that the first scraper 407 scrapes off the sludge adhering to the inner wall surface of the cylinder 31 and then drops it into the inside of the cylinder 31. At the same time, the first scraper 407 drives the discharge plate 408 to rotate, so as to scrape the sludge from the discharge port 33 and enter the inside of the discharge bin 7 through the electric valve 6.

[0023] To prevent large clumps of sludge from affecting dewatering efficiency, 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 31, and the outer wall of the connecting column 409 is axially provided with multiple groups of first bevel gears 410, and 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 interior of the rotating sleeve 402, and the end of the connecting rod 411 extending into the interior of the rotating sleeve 402 is provided with a second bevel gear 412 adapted to the first bevel gear 410, and the outer wall of the connecting rod 411 is axially provided with multiple groups of crushing blades 413.

[0024] When in use, through the fixed connection between the connecting column 409 and the cylinder 31, the connecting column 409 will remain stationary when the rotating sleeve 402 rotates, and the rotating sleeve 402 will drive the connecting rod 411 to rotate. Through the engagement 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 will also rotate, causing the crushing blades 413 on the surface of the connecting rod 411 to rotate at high speed, thereby breaking up large pieces of sludge close to the surface of the crushing blades 413, thereby preventing the large pieces of sludge from affecting the dehydration efficiency of the device.

[0025] To prevent sludge from passing through the outlet hole 32, refer to Fig. 9 As shown in the figure, the filtering mechanism 5 includes a drain pipe 501 installed inside the water outlet 32, a filter net 502 adapted to the water outlet 32 ​​is arranged on one side of the drain pipe 501 close to the water outlet 32, and a drain port 503 is arranged on one side of the drain pipe 501 close to the outer wall of the cylinder 31.

[0026] When in use, sewage will enter the interior of the drain pipe 501 through the water outlet hole 32. At this time, the setting of the filter net 502 can prevent sludge from entering the interior of the drain pipe 501. The end of the drain pipe 501 close to the water outlet hole 32 is higher, and the end away from the water outlet hole 32 is lower. Therefore, the sewage entering the drain pipe 501 will flow downward along the drain pipe 501 and flow into the interlayer between the body 21 and the cylinder 31 through the drain port 503.

[0027] To prevent the sludge from clogging the filter holes on the surface of the filter 502, please refer to Figure 3 and Fig. 9 As shown in the figure, the filtering mechanism 5 also includes a limit block 504 arranged on the surface of the drain outlet 503 and adapted to the drain outlet 503, a spring sheet 505 adapted to the limit block 504 is arranged on the surface of the drain pipe 501, a connecting spring 506 is fixedly connected to the inside of the drain pipe 501, and a push rod 507 is fixedly connected to the connecting spring 506 on the side away from the drain outlet 503. A piston 508 adapted to the drain pipe 501 is arranged on the push rod 507 on the side close to the drain outlet 503, and a limit plate 509 adapted to the push rod 507 is arranged on the inner wall of the tank body 21.

[0028] When in use, the filter cartridge 3 drives the drain pipe 501 to rotate. When the drain pipe 501 and the limit plate 509 are at the same horizontal line, the limit plate 509 will squeeze the push rod 507, thereby pushing the push rod 507 to slide inside the drain pipe 501 and squeeze 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 sheet 505, so that the limit block 504 and the drain port 503 are closed. At this time, the piston 508 continues to The push rod 507 continues to slide inside the drain pipe 501 and squeeze the internal air of the drain pipe 501, so that the air is blown to the inside of the filter cartridge 3 through the filter screen 502. In this process, the sludge adhering to the surface of the filter screen 502 can be backwashed by the gas. When the push rod 507 is separated from the limit plate 509, the connecting spring 506 will push the push rod 507 to reset the piston 508 to generate a suction force through the drain pipe 501, and the sewage inside the filter cartridge 3 is sucked into the drain pipe 501, thereby improving the dehydration efficiency of the sludge.

[0029] See also Figure 7 As shown in the figure, the unloading mechanism 10 includes a material storage trough 1001 and a molded component. The interior of the mounting frame 1 is provided with a material storage trough 1001 adapted to the discharge port 9. An electric slide rail 1002 is fixedly connected to the inner wall of the material storage trough 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.

[0030] When in use, after the crushed sludge enters the interior of the storage tank 1001 through the discharge port 9, the sludge will accumulate directly below the discharge port 9. At this time, the electric slider 1003 slides on the surface of the electric slide rail 1002, causing the second scraper 1004 to scrape back and forth on the surface of the storage tank 1001, so that the sludge can be evenly filled into the storage tank 1001.

[0031] To prevent the dehydrated sludge from being dispersed in the air, please refer to Figure 7-Figure 8As 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 pressing roller 1007 is fixedly connected to the outer wall of the connecting shaft 1006, and a plurality of pressing blocks 1008 are arranged on the outer circumferential surface of the pressing 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, and a rotating column 1010 is rotatably connected inside the mounting frame 1, and a connecting gear is arranged on the outer wall of one end of the rotating column 1010. 1009 is adapted to a linkage gear 1011, a prefabricated roller 1012 is fixedly connected to the outer wall of the rotating column 1010, and a prefabricated groove 1013 adapted to the pressing block 1008 is arranged on the outer circumferential surface of the prefabricated roller 1012 along the circumferential direction, a reset spring 1014 is fixedly connected to the inner wall of the prefabricated roller 1012, and a push plate 1015 adapted to the prefabricated groove 1013 is arranged on one side of the reset spring 1014 close to the prefabricated groove 1013, and a discharge groove 1016 adapted to the prefabricated groove 1013 is arranged on the side of the mounting frame 1 close to the conveyor belt 11.

[0032] When in use, the sludge inside the storage tank 1001 will enter the inside of the prefabricated groove 1013 on the surface of the prefabricated roller 1012, and then the external power supply is connected to start the driving motor 1005 to drive the pressing 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, the linkage gear 1011 will drive the rotating column 1010 to rotate synchronously, so that the prefabricated roller 1012 and the pressing roller 1007 rotate synchronously. When the pressing roller 1007 and the prefabricated roller 1012 rotate, the pressing block 1008 will close with the prefabricated trough 1013, so that the pressing block 1008 presses the sludge inside the prefabricated trough 1013, compacts it into a block and squeezes the return spring 1014. When the sludge block moves to the top of the discharge trough 1016 with the rotation of the prefabricated roller 1012, the return spring 1014 pushes the push plate 1015 to slide inside the prefabricated trough 1013, pushing the sludge block into the discharge trough 1016 and falling onto the surface of the conveyor belt 11.
