Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste treatment technology, specifically to a solid waste drying device. Background Technology
[0002] High-efficiency solid waste drying equipment is used to evaporate or remove moisture from solid waste to achieve dryness. It can be widely used in wastewater treatment, food processing, chemical, pharmaceutical and other industries.
[0003] Existing patent document CN221425273U discloses a solid waste drying device. It utilizes a support frame, a first motor, a fixing ring, an insulated outer shell, a heating cylinder, a drying cylinder, a rotating shaft, and heating rods to create a large opening for material feeding and discharging, improving feeding and discharging efficiency. Simultaneously, it heats both the outer surface and center of the drying cylinder, enhancing drying efficiency. Furthermore, it incorporates a second motor, a rotating shaft, a rotating plate, a third motor, a scraper, a lead screw, a pusher, and brushes to scrape the solid waste on the inner wall of the drying cylinder, reducing contaminant adhesion and preventing overheating. It also cleans residual material from the surface of the stirring blades, reducing discharge residue and actively pushing out material to accelerate discharge, thus improving work efficiency. However, in practice, the drying device in CN221425273U lacks a solid waste crushing function, requiring the solid waste to be crushed on a crushing device before being transferred to the drying device. This increases processing steps and reduces drying efficiency. Therefore, a solid waste drying device is urgently needed. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a solid waste drying device, including a main body of the device, a processing box is provided on the left side of the main body of the device, and a drying box is installed on the outside of the main body of the device. The processing box is provided with a crushing structure inside, and the drying box is provided with a drying structure inside.
[0006] The crushing structure includes a first motor, the output end of which is provided with a transmission gear set, and a crushing roller is installed on the transmission gear set. A second feed hopper is provided on the left side of the processing box, and a second motor is installed on the inner side of the processing box. The output end of the second motor is provided with a blade, and a sliding plate is provided on the second motor.
[0007] The drying structure includes a limiting frame with an adjustment groove at its bottom. A feeding plate is connected to the inner side of the processing box. A third motor is installed at the rear end of the drying box. A first pulley is provided at the output end of the third motor. A second pulley is provided to the left of the first pulley, and a belt is sleeved on the outer side of the first pulley. A pushing roller is installed on the first pulley. A pressing roller is provided to the left of the pushing roller, and a scraper is provided on the outer wall of the pushing roller.
[0008] Preferably, a first feed hopper is provided at the top of the processing box, a hot air blower is installed on the drying box, an air outlet hood is provided at the bottom of the hot air blower, and a conveyor belt is installed on the inner side of the main body of the equipment.
[0009] Preferably, the first motor and the processing box are fixedly installed by a bracket, the number of the crushing rollers is two, the two crushing rollers are connected by a transmission gear set, and the sliding plate is welded to the inner wall of the processing box.
[0010] Preferably, the second motor and the sliding plate are fixedly installed by a bracket, the second feed hopper extends through the inner side of the processing box, and the outer wall of the processing box is provided with a discharge trough.
[0011] Preferably, the limiting frame and the processing box are fixedly installed by bolts, and the limiting frame is engaged on the outside of the feeding plate. The third motor and the drying box are fixedly installed by a bracket, and the second pulley is rotatably connected to the bracket by a bearing.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0015] First, this utility model, by setting up crushing rollers, transmission gear sets, and blades, pours the solid waste to be crushed into the processing box through the first feed hopper. The first motor drives the two crushing rollers to rotate in opposite directions through the transmission gear set, squeezing and crushing the falling solid waste. At the same time, the second motor drives the blades to rotate, crushing the falling waste a second time. After the solid waste is completely crushed, it slides down through the sliding plate and accumulates on the discharge plate. If the solid waste itself is relatively small, it can directly enter the processing box through the second feed hopper and accumulate on the discharge plate, which facilitates the reduction of the volume of the crushed solid waste and rapid drying.
[0016] Secondly, this utility model, through its design, allows for pre-adjustment of the height of the limiting frame based on the desired rapid drying height of the waste. After the limiting frame is moved and adjusted outside the processing box and then fixed with bolts, the gap between the adjusting groove at the bottom of the limiting frame and the feeding plate is adjusted. This, in turn, adjusts the height at which the waste is laid on the conveyor belt. Under its own weight, the waste passes through the adjusting groove and continues to fall, eventually laying flat on the conveyor belt for transport. Meanwhile, the hot air blower on the drying box operates, blowing hot air through the air outlet hood onto the flattened waste for drying. Due to the appropriate thickness of the waste, it is laid flat... The increased drying area enables complete drying during waste transportation. The operation of the third motor is controlled by existing technology. After the third motor starts running, it drives the first pulley at the output end to rotate. The first pulley drives the second pulley to rotate via a belt. The first and second pulleys can simultaneously drive the pusher roller and the crushing roller to rotate in the same direction. The crushing roller first crushes the dried waste below, while the pusher roller pushes the crushed waste away from the conveyor belt through the rotating scraper and rubber scraper, which facilitates unloading. Thus, the drying of solid waste is completed. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-4A solid waste drying device includes a main body 1, a processing box 2 on the left side of the main body 1, and a drying box 6 installed on the outside of the main body 1. A crushing structure 4 is installed inside the processing box 2, and a drying structure 5 is installed inside the drying box 6. The crushing structure 4 includes a first motor 401, a transmission gear set 402 at the output end of the first motor 401, and a crushing roller 403 mounted on the transmission gear set 402. A second feed hopper 407 is located on the left side of the processing box 2, and a second feed hopper 407 is installed inside the processing box 2. The machine 404 has a blade 405 at its output end and a sliding plate 406 on its upper end. A first feed hopper 3 is located at the top of the processing box 2. A hot air blower 7 is installed on the drying box 6, and an air outlet hood 8 is located at the bottom of the hot air blower 7. A conveyor belt 9 is installed inside the main body 1. The first motor 401 is fixedly installed to the processing box 2 via a bracket. There are two crushing rollers 403, which are connected by a transmission gear set 402. The sliding plate 406 is welded to the inner side of the processing box 2. The second motor 404 and the sliding plate 406 are fixedly installed by a bracket. The second feed hopper 407 extends through to the inside of the processing box 2. The outer wall of the processing box 2 is provided with a discharge chute. The solid waste to be crushed is poured into the processing box 2 through the first feed hopper 3. At this time, the first motor 401 runs. The internal technology of the first motor 401 is existing technology. After the first motor 401 runs, it drives the transmission gear set 402 at the output end to rotate. When the transmission gear set 402 rotates, it drives the two crushing rollers 403 to rotate in opposite directions, squeezing the falling solid waste. The waste is crushed under pressure, and at the same time, the second motor 404 operates. The internal technology of the second motor 404 is existing technology. After the second motor 404 starts running, it drives the blade 405 at the output end to rotate. When the blade 405 rotates at high speed, it crushes the falling waste a second time. After the solid waste is completely crushed, it slides down through the sliding plate 406 and accumulates on the discharge plate 502. If the solid waste itself is relatively small, it can directly enter the processing box 2 through the second feed hopper 407 and accumulate on the discharge plate 502, which facilitates the reduction of the volume of the crushed solid waste and rapid drying.
[0027] Please see Figures 5-7A solid waste drying device, wherein the drying structure 5 includes a limiting frame 501, an adjusting groove 503 at the bottom of the limiting frame 501, a feeding plate 502 connected to the inner side of the processing box 2, a third motor 504 installed at the rear end of the drying box 6, a first pulley 505 at the output end of the third motor 504, a second pulley 506 on the left side of the first pulley 505, and a belt 507 sleeved on the outer side of the first pulley 505, a pushing roller 508 installed on the first pulley 505, a pressing roller 510 on the left side of the pushing roller 508, and a scraper 509 on the outer wall of the pushing roller 508, and the limiting frame 501. The processing box 2 is fixedly installed with bolts, and the limiting frame 501 is engaged with the outside of the feeding plate 502. The third motor 504 is fixedly installed with the drying box 6 through a bracket, and the second pulley 506 is rotatably connected to the bracket through a bearing. The pusher roller 508 and the crushing roller 510 are fixedly connected to the first pulley 505 and the second pulley 506 respectively, and the pusher roller 508 and the crushing roller 510 are rotatably connected through the first pulley 505, the second pulley 506 and the belt 507. The ends of the pusher roller 508 and the crushing roller 510 are rotatably connected to the drying box 6 through bearings. The end of the scraper 509 is provided with a rubber scraper, which can be pre-selected according to the waste. The height of the drying chamber 6 is adjusted by moving the limiting frame 501 to the outside of the processing box 2. After the limiting frame 501 is moved and adjusted, it is fixed with bolts. This adjusts the gap between the adjusting groove 503 at the bottom of the limiting frame 501 and the feeding plate 502, thereby adjusting the height of the waste on the conveyor belt 9. At this time, the waste, under its own weight, passes through the adjusting groove 503 and continues to fall, eventually spreading flat on the conveyor belt 9 for transportation. Meanwhile, the hot air blower 7 on the drying box 6 operates, blowing hot air onto the spread waste through the air outlet hood 8 to dry it. Because the waste is spread out at an appropriate thickness, the drying area is increased, allowing for complete drying during waste transportation. The entire drying process is carried out, and the operation of the third motor 504 is controlled. The internal technology of the third motor 504 is existing technology. After the third motor 504 is running, it drives the first pulley 505 at the output end to rotate. The first pulley 505 drives the second pulley 506 to rotate through the belt 507. Then, the first pulley 505 and the second pulley 506 can simultaneously drive the pusher roller 508 and the crushing roller 510 to rotate in the same direction. This allows the crushing roller 510 to crush the dried waste below first, while the pusher roller 508 pushes the crushed waste to separate from the conveyor belt 9 through the rotating scraper 509 and the rubber scraper, which facilitates the unloading of the material. Thus, the drying of solid waste is completed.
[0028] In operation, the solid waste to be crushed is poured into the processing box 2 through the first feed hopper 3. At this time, the first motor 401 runs. The internal technology of the first motor 401 is existing technology. After the first motor 401 runs, it drives the transmission gear set 402 at the output end to rotate. When the transmission gear set 402 rotates, it drives the two crushing rollers 403 to rotate in opposite directions, crushing the falling solid waste. At the same time, the second motor 404 runs. The internal technology of the second motor 404 is existing technology. After the second motor 404 runs, it drives the blades 405 at the output end to rotate. The high-speed rotation further crushes the falling waste, ensuring complete crushing. The waste then slides down the sliding plate 406 and accumulates on the discharge plate 502. If the solid waste is relatively small, it can directly enter the processing box 2 through the second feed hopper 407 and accumulate on the discharge plate 502, facilitating volume reduction and rapid drying. The height of the limiting frame 501 is pre-adjusted based on the desired drying height of the waste. After adjustment by moving the limiting frame 501 outside the processing box 2, it is secured with bolts. The adjustment groove at the bottom of the limiting frame 501... The gap between 503 and the feeding plate 502 is adjusted, thereby adjusting the height of the waste laid on the conveyor belt 9. Under its own weight, the waste continues to fall through the adjusting groove 503 and finally lies flat on the conveyor belt 9 for transport. Meanwhile, the hot air blower 7 on the drying box 6 operates, blowing hot air onto the flattened waste through the air outlet hood 8 to dry it. Because the waste is laid out with an appropriate thickness, the drying area is increased, allowing for complete drying during transport. Since the waste, which contains moisture, will clump together in large areas after drying, the third motor 504 is controlled to operate. The internal technology of motor 504 is existing technology. After the third motor 504 is running, it drives the first pulley 505 at the output end to rotate. The first pulley 505 drives the second pulley 506 to rotate through belt 507. Then, the first pulley 505 and the second pulley 506 can simultaneously drive the pusher roller 508 and the crushing roller 510 to rotate in the same direction. This allows the crushing roller 510 to crush the dried waste below first, while the pusher roller 508 pushes the crushed waste to separate from the conveyor belt 9 through the rotating scraper 509 and rubber scraper, which facilitates the unloading of the material. Thus, the drying of solid waste is completed.
