Description

Technical Field

[0001] The present invention belongs to the technical field of garbage recycling and treatment, and specifically relates to a heat treatment drying device for organic solid waste. Background Art

[0002] In daily life and manufacturing, it is inevitable to generate some solid waste, including but not limited to various solid wastes such as crop straws, kitchen waste, fruit and vegetable residues, livestock and poultry manure, and residues generated from food processing. These are all generated during life or agricultural planting processes, and these wastes will ultimately all be piled up in landfills. To prevent these wastes from accumulating for a long time and generating substances such as germs and insect eggs that affect the natural environment, generally, technical means such as pulverization and heat treatment drying are used to reduce harmful substances such as microorganisms and insect eggs therein; In the existing technical solutions, mainly, a magnetron is used to generate microwaves that pass through the waste materials, so that the water molecules therein are vibrated at a high frequency and generate heat energy. Usually, a stirring rod is also provided inside the device. However, in the existing technical solutions, simply turning the waste materials by the stirring rod cannot well make the waste materials contact the microwaves and accelerate the time for the evaporation of water molecules. For large pieces of waste materials, more time will be spent on drying. Moreover, the magnetron generally heats the entire waste materials, which further slows down the evaporation speed of water in the waste materials. Therefore, we provide a heat treatment drying device for organic solid waste. Summary of the Invention

The motor drives the plurality of extrusion assemblies to jointly squeeze water in the waste material. A drainage port for drainage is arranged at the bottom of the working box.

[0005] Preferably, the drying component further comprises a discharge port installed on the top of the working box, a feed port is installed on the periphery of the discharge port, and a filter cloth for preventing waste leakage is provided at the connection between the drainage port and the working box.

[0006] Preferably, the driving shaft is movably connected to the bottom of the working box, the diversion assembly also includes a metal bellows, the bottom of the arc-shaped bracket is connected to the outer periphery of the support tube through the metal bellows, and the metal bellows is covered on the outer periphery of the spring.

[0007] Preferably, the magnetron is always located at the top of the supporting plate, the arc-shaped bracket is movably connected to the outer periphery of the supporting tube, and the spring always supports the arc-shaped bracket to be located at the top of the supporting tube.

[0008] Preferably, the cutting assembly includes a protective tube movably connected to the outer periphery of the supporting tube, and a plurality of metal plates are arranged at equal angles in the circumferential direction on the outer periphery of the protective tube. Each of the metal plates is transmission connected to the bottom of the arc-shaped bracket through a telescopic rod, and the inner wall of the working box is connected to steel knives through a plurality of support plates arranged at equal angles in the circumferential direction, and the number of the steel knives is equal to the number of the support plates.

[0009] Preferably, the outer side of the metal plate is provided with a notch for a steel knife to penetrate, and the side surface of the metal plate is provided with metal barbs arranged at equal distances.

[0010] Preferably, the extrusion assembly includes a guide rod movably passing through the bottom of the working box, the end ball shaft of the guide rod is installed with a guide plate, the side of the guide plate is installed with an arc plate, the output shaft of the motor is connected with a metal ring through a reciprocating threaded shaft, the guide rod is welded to the metal ring, the part of the guide plate used for the guide rod to slide is inclined, and the bottom of the guide plate and the arc plate are both tightly attached to the inside of the working box.

[0011] Preferably, the extrusion assembly further includes a limiting plate slidably mounted on the top of the arc-shaped plate. One end of the bottom of the limiting plate is elastically connected to the arc-shaped plate through a spring piece. After the arc-shaped plates are gathered, they form a cylindrical shape, and after the limiting plates are combined, they form a disc shape and limit the leakage of waste from the gaps between every two adjacent arc-shaped plates.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the cooperation of structures such as the diversion assembly and the support cylinder, the motor drives the screw conveyor rod to rotate through the driving shaft and the helical gear to convey waste to the top of the bearing plate. Its weight presses the bearing plate to descend, and the screw conveyor rod stops rotating. The arc-shaped rods at the edges of the arc-shaped brackets spread the waste flat to the top of the bearing plate. The microwave emitted by the magnetron evaporates the moisture in the waste. The weight of the waste gradually decreases, and the spring slowly pushes the arc-shaped bracket back to the initial position. The arc-shaped bracket pushes the waste to fall from the gap between the edge of the bearing plate and the inclined surface of the inner wall of the working box. The helical gear is repositioned in the groove inside the screw conveyor rod, and then drives the screw conveyor rod to resume the conveying work. During the cyclic conveying process, each part of the waste can be dried separately, thereby further improving the heat treatment efficiency of the device.

[0013] Through the cooperation of structures such as the cutting assembly and the drying assembly, the arc-shaped bracket rotates and drives the metal plate to rotate through the telescopic rod and squeezes the waste to move. When the metal plate pushes the waste, the metal barbs will insert into the rhizome. Its inclined setting makes it difficult for the rhizome to break away from the metal barbs. When the steel knife penetrates the slot on the metal plate, it can better cut and tear the waste, and it is also convenient for the waste to enter the inside of the support cylinder subsequently, avoiding jamming during the operation of the device, and at the same time enabling the moisture inside it to be more thoroughly evaporated by the microwave.

[0014] Through the cooperation of structures such as the extrusion assembly and the support cylinder, each guide rod restricts the metal ring from rotating. The output shaft of the motor drives the guide rod to reciprocate up and down through the metal ring. When the guide rod descends along the hypotenuse of the guide plate, the arc-shaped plate approaches the center point of the support plate. The side of the limiting plate first contacts the inner wall of the support plate. The limiting plate restricts the waste located between the arc-shaped plate and the support cylinder from being squeezed by the moving arc-shaped plate. The squeezed moisture is discharged through the drain port, and the squeezed waste will contact the slot at the bottom of the support cylinder immediately, and thus is conveyed away by the screw conveyor rod, further improving the drying efficiency of the device. The squeezed sewage can also be collected and processed separately. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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 the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] As Figures 1 to 8 shown, the present invention provides a heat treatment drying device for organic solid waste, including a drying assembly 1. The drying assembly 1 includes a working box 11. The edge of the top of the working box 11 is chamfered, and a magnetron is arranged on the chamfered surface. A support cylinder 14 is fixedly installed inside the working box 11, and a notch is arranged at the bottom of the support cylinder 14; further includes: A motor 2 arranged at the bottom of the working box 11; A shunt assembly 3 installed inside the working box 11; The shunt assembly 3 includes a threaded conveying rod 31 movably clamped inside the working box 11. A driving shaft 32 is rotatably installed inside the threaded conveying rod 31. A helical gear 37 is installed on the outer periphery of the driving shaft 32. A groove adapted to the teeth on the helical gear 37 is arranged inside the threaded conveying rod 31. The output shaft of the motor 2 is polygonal and is movably installed inside the driving shaft 32; An arc-shaped bracket 33 is installed at the top of the driving shaft 32. The arc-shaped bracket 33 is elastically connected to the outer periphery of the support cylinder 14 through a spring 35. The outer periphery of the arc-shaped bracket 33 is movably clamped with a bearing plate 34, and the bearing plate 34 moves vertically inside the working box 11; An inclined surface is arranged below the bearing plate 34 on the inner wall of the working box 11, and a distance is reserved between the vertex of the inclined surface and the edge of the bearing plate 34; A cutting assembly 4 rotatably installed on the outer periphery of the support cylinder 14; A plurality of extrusion assemblies 5 are circumferentially and equiangularly arranged at the lower end inside the working box 11. The motor 2 drives the plurality of extrusion assemblies 5 to jointly extrude the water in the waste material, and a drain port 13 for draining water is arranged at the bottom of the working box 11.

[0019] The drying assembly 1 further includes a discharge port 12 installed at the top of the working box 11. The outer periphery of the discharge port 12 is installed with a feed port 15, and a filter cloth for blocking the leakage of waste material is arranged at the connection between the drain port 13 and the working box 11.

[0020] The magnetron is always located at the top of the bearing plate 34. The arc-shaped bracket 33 is movably clamped to the outer periphery of the support cylinder 14, and the spring 35 always supports the arc-shaped bracket 33 at the top of the support cylinder 14.

[0021] Using the above method: First, place the waste material inside the working box 11 through the feeding port 15. When the output shaft of the motor 2 drives the threaded conveying rod 31 to rotate through the driving shaft 32 and the helical gear 37, the threaded conveying rod 31 and the supporting cylinder 14 will convey the waste material at the bottom of the working box 11 to the top of the supporting cylinder 14 through the notch at the bottom of the supporting cylinder 14. Finally, the waste material will be located on the top of the bearing plate 34. Since the moisture content in the undried waste material is high, its weight will press the bearing plate 34 to descend. The edge of the bearing plate 34 is closely attached to the inner wall of the working box 11, and the driving shaft 32 also descends. Moreover, the helical gear 37 is no longer engaged with the notch inside the threaded conveying rod 31, and the threaded conveying rod 31 stops rotating and will no longer convey waste material to the top of the supporting cylinder 14. However, the output shaft of the motor 2 will still drive the arc-shaped bracket 33 to rotate through the driving shaft 32. The arc-shaped rod at the edge of the arc-shaped bracket 33 pushes the waste material and spreads it flat on the top of the bearing plate 34. The microwave emitted by the magnetron evaporates the moisture in the waste material, and the formed water vapor is discharged through the discharge port 12. During the continuous rotation and turning of the arc-shaped bracket 33, the time for moisture evaporation is shortened. During the moisture evaporation process, the weight of the waste material on the top of the bearing plate 34 gradually decreases, and the elastic force of the spring 35 slowly pushes the arc-shaped bracket 33 back to its original position. Finally, the bearing plate 34 is completely in its original position, and the arc-shaped rod around the arc-shaped bracket 33 pushes the waste material to fall through the gap between the edge of the bearing plate 34 and the inclined surface of the inner wall of the working box 11. At this time, the helical gear 37 is also repositioned in the notch inside the threaded conveying rod 31, thereby driving the threaded conveying rod 31 to resume the conveying work. During the cyclic conveying process, each part of the waste material can be dried separately, thus further improving the heat treatment efficiency of the device; After the drying work is completed, keep the device running. When the dried waste material is conveyed to the top of the bearing plate 34, connect an external pipeline to the fan, and then extract the waste material outside the device. As a result, the weight borne on the bearing plate 34 can never compress the spring 35, and the threaded conveying rod 31 can continuously convey the dried waste material, thereby improving the convenience of the subsequent work of the device.

[0022] As Figures 1 - 4 shown, the driving shaft 32 is movably engaged with the bottom of the working box 11. The shunt assembly 3 further includes a metal bellows 36. The bottom of the arc-shaped bracket 33 is connected to the outer periphery of the supporting cylinder 14 through the metal bellows 36, and the metal bellows 36 is wrapped around the outer periphery of the spring 35.

[0023] The above method is adopted: the connection method between the driving shaft 32 and the working box 11 ensures that the position of the driving shaft 32 remains unchanged during the rotation, thereby better conveying the waste. When the spring 35 is compressed, the metal bellows 36 can ensure that the waste will not be stuck in the spring 35, thereby causing a jam. Furthermore, the outer periphery of the metal bellows 36 is sprayed with anti-corrosion material, thereby avoiding corrosion of the metal bellows 36 after long-term work.

[0024] like Figures 1 - 3 and Figure 7 As shown, the cutting assembly 4 includes a protective tube 45 movably clamped on the outer periphery of the supporting tube 14, and a plurality of metal plates 43 are arranged at equal angles in the circumferential direction on the outer periphery of the protective tube 45. Each metal plate 43 is transmission connected to the bottom of the arc-shaped bracket 33 through a telescopic rod 46, and the inner wall of the working box 11 is connected to steel knives 42 through a plurality of support plates 41 arranged at equal angles in the circumferential direction, and the number of steel knives 42 is equal to the number of support plates 41.

[0025] The above method is adopted: when the arc-shaped bracket 33 rotates, it drives the metal plate 43 to rotate and squeeze the waste to move through the telescopic rod 46. When the waste is pushed to contact the steel knife 42, it cooperates with the metal plate 43 to cut the waste, so that the waste is cut into small pieces, which is convenient for subsequent entry into the interior of the support tube 14, avoiding the jamming phenomenon of the device during operation, and at the same time enabling the moisture inside to be more thoroughly evaporated by microwaves. The output shaft of the motor 2 is always connected to the driving shaft 32, and the driving shaft 32 is fixedly connected to the arc-shaped bracket 33. The metal plate 43 will always be in a rotating state, thereby extending the cutting time and further improving the drying efficiency.

[0026] like Figures 1 - 4 As shown, the outer side of the metal plate 43 is provided with a notch for the steel knife 42 to pass through, and the side surface of the metal plate 43 is provided with metal barbs 44 arranged at equal distances.

[0027] The above method is used: the dried waste usually also contains roots and stems of crops and rotten fruits and vegetables in kitchen waste. When the metal plate 43 pushes the waste, the metal barbs 44 will be inserted into the roots and stems. The metal barbs 44 are tilted so that it is difficult for the roots and stems to escape from the metal barbs 44. When the steel knife 42 penetrates the notch on the metal plate 43, the waste can be better cut and torn.

[0028] like Figures 1 - 3 and Figure 8As shown in the figure, the extrusion assembly 5 includes a guide rod 54 that movably penetrates the bottom of the working box 11. The end of the guide rod 54 is ball-mounted with a guide plate 52. An arc plate 51 is mounted on the side of the guide plate 52. The output shaft of the motor 2 is connected with a metal ring through a reciprocating threaded shaft. The guide rod 54 is welded to the metal ring. The part of the guide plate 52 for the sliding of the guide rod 54 is inclined. The bottoms of both the guide plate 52 and the arc plate 51 are closely attached to the inside of the working box 11.

[0029] The extrusion assembly 5 further includes a limit plate 53 slidably mounted on the top of the arc plate 51. One end of the bottom of the limit plate 53 is elastically connected to the arc plate 51 through a spring piece 55. After the arc plates 51 are gathered, they form a cylindrical shape. After the limit plates 53 are combined, they form a disc shape and limit the leakage of waste from the gap between every two adjacent arc plates 51.

[0030] Using the above method: Each guide rod 54 restricts the metal ring from rotating. When the output shaft of the motor 2 rotates, it will drive the guide rod 54 to reciprocate up and down through the metal ring. When the guide rod 54 descends along the hypotenuse of the guide plate 52, the arc plate 51 approaches the center point of the support plate 41. The side of the limit plate 53 first contacts the inner wall of the support plate 41. During this process, the limit plate 53 restricts the waste located between the arc plate 51 and the support cylinder 14 from being extruded by the moving arc plate 51. The moisture in the waste outside the arc plate 51 is in a saturated state, and the extruded moisture is discharged through the drain port 13. The filter cloth arranged at the connection place will force the waste to stay inside the working box 11, and the extruded waste will contact the notch at the bottom of the support cylinder 14 for the first time, so as to be conveyed away by the screw conveyor rod 31, further improving the drying efficiency of the device. The squeezed sewage can also be collected and processed separately.

[0031] The working principle and usage process of the present invention: First, place the waste material inside the working box 11 through the feeding port 15. The output shaft of the motor 2 drives the threaded conveying rod 31 to rotate through the driving shaft 32 and the helical gear 37. The threaded conveying rod 31 conveys the waste material at the bottom of the working box 11 through the combined support cylinder 14 to the top of the support cylinder 14 through the notch at the bottom of the support cylinder 14. Its weight will press the bearing plate 34 to descend, and the helical gear 37 will no longer be engaged in the notch inside the threaded conveying rod 31, and the threaded conveying rod 31 will stop rotating. The arc-shaped rod at the edge of the arc-shaped bracket 33 pushes the waste material and spreads it flat on the top of the bearing plate 34. The microwave emitted by the magnetron evaporates the moisture in the waste material, and the water vapor is discharged through the discharge port 12. During the process of moisture evaporation, the weight of the waste material on the top of the bearing plate 34 gradually decreases, and the spring 35 slowly pushes the arc-shaped bracket 33 back to its original position. The arc-shaped rod around the arc-shaped bracket 33 pushes the waste material to fall through the gap between the edge of the bearing plate 34 and the inclined surface of the inner wall of the working box 11. At this time, the helical gear 37 also re-locates in the notch inside the threaded conveying rod 31, and then drives the threaded conveying rod 31 to resume the conveying work; When the arc-shaped bracket 33 rotates, it drives the metal plate 43 to rotate and squeeze the waste material to move through the telescopic rod 46. When the waste material is pushed into contact with the steel knife 42, it cuts the waste material jointly with the metal plate 43; Each guide rod 54 restricts the metal ring from rotating. When the output shaft of the motor 2 rotates, it will drive the guide rod 54 to reciprocate up and down through the metal ring. When the guide rod 54 descends along the hypotenuse of the guide plate 52, the arc-shaped plate 51 approaches the center point of the support plate 41. The side of the limit plate 53 first contacts the inner wall of the support plate 41. During this process, the limit plate 53 restricts the waste material located between the arc-shaped plate 51 and the support cylinder 14 from being squeezed by the moving arc-shaped plate 51, and the squeezed moisture is discharged through the drain port 13; After the drying work is completed, keep the device running. When the dried waste material is conveyed to the top of the bearing plate 34, connect an external pipeline to the fan, and then extract the waste material to the outside of the device. The weight borne on the bearing plate 34 can never compress the spring 35, while the threaded conveying rod 31 can continuously convey the dried waste material, thus improving the convenience of the subsequent work of the device.

[0032] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
