Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection equipment, and particularly relates to a chain-type drying equipment for kitchen waste. Background Art

[0002] Kitchen waste, also known as kitchen garbage, generally refers to the food waste generated during our kitchen cooking process, including leftovers, fruit peels, eggshells, tea dregs, etc. After being processed, kitchen waste can be recycled, used as fertilizer and feed. Kitchen waste is generally classified as wet waste, which has the characteristics of high water content, high organic matter and oil content, easy to rot and deteriorate, and easy to breed germs. If the water in the kitchen waste cannot be removed well, the kitchen waste is very easy to rot and produce a foul smell, affecting subsequent utilization.

[0003] In the current treatment process for kitchen waste, the drying equipment is an essential link. Its main function is to evaporate the water in the kitchen waste through high-temperature hot air or other heat sources. However, traditional kitchen waste drying equipment usually adopts an intermittent working mode, that is, first drying a part of the kitchen waste and then drying another part of the kitchen waste, which makes it difficult to meet the requirements of large-scale and continuous treatment. In addition, the existing kitchen waste drying equipment generally has the problem of uneven drying. This is mainly due to the uneven distribution, movement state of the garbage in the equipment and the heat source distribution during the drying process. Specifically, the garbage often exists in a piled or stacked manner in the drying equipment, resulting in over-drying of the part close to the heat source and under-drying of the part far from the heat source. This uneven drying effect not only reduces the drying efficiency but also may affect the smooth progress of subsequent treatment processes. Summary of the Invention

[0015] In order to make the purpose, technical solutions and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0016] Example 1, as Figure 1-8 As shown, a chain-type drying device for kitchen waste comprises a sealing box 1, a feeding conveyor belt 2 is fixedly installed above the inner cavity of the sealing box 1, a plurality of drying conveyor belts 3 are installed side by side up and down in the middle of the inner cavity of the sealing box 1, and a discharging conveyor belt 4 is fixedly installed below the inner cavity of the sealing box 1. The conveying direction of the feeding conveyor belt 2 is opposite to the conveying direction of the uppermost drying conveyor belt 3, and the conveying directions of two adjacent drying conveyor belts 3 are opposite. The feeding conveyor belt 2 and the plurality of drying conveyor belts 3 cooperate to form a "Z"-shaped conveying path, and the output end of the drying conveyor belt 3 located at the lowermost corresponds to the upper surface of the discharging conveyor belt 4; the input end of the feeding conveyor belt 2 passes through the sealing box 1 and is fixedly installed with a feeding frame cover 5, and the output end of the discharging conveyor belt 4 passes through the sealing box 1 and corresponds to the input end of the external conveyor belt 6; The feeding conveyor belt 2 includes a first conveying frame 21 and a first mesh chain conveyor belt 22. Both ends of the inner cavity of the first conveying frame 21 are rotatably connected to the first transmission wheels through bearings, and the two first transmission wheels are transmission-connected by the first mesh chain conveyor belt 22; the front side of the first conveying frame 21 is provided with a plurality of first drawer holes 23 arranged horizontally side by side, and a first drawer cabinet 24 is movably installed in each first drawer hole 23. A first ventilation plate 25 is provided above the first drawer cabinet 24, and the first ventilation plate 25 is fixedly embedded in the upper surface of the first conveying frame 21. A plurality of ventilation holes are provided on the surface of the first ventilation plate 25. The inner cavity of the first drawer cabinet 24 is communicated with the first mesh chain conveyor belt 22 through the first ventilation plate 25; The drying conveyor belt 3 includes a second conveyor frame 31 and a second mesh chain conveyor belt 32. Both ends of the inner cavity of the second conveyor frame 31 are rotatably connected to second driving wheels through bearings, and the two second driving wheels are drivingly connected through the second mesh chain conveyor belt 32. A plurality of second drawer holes 33 are horizontally arranged side by side on the front side surface of the second conveyor frame 31. A second drawer cabinet 34 is movably installed in each second drawer hole 33. A second ventilation plate 35 is arranged above the second drawer cabinet 34. The second ventilation plate 35 is fixedly embedded in the upper surface of the second conveyor frame 31. A plurality of ventilation holes are formed on the surface of the second ventilation plate 35. The inner cavity of the second drawer cabinet 34 is communicated with the second mesh chain conveyor belt 32 through the second ventilation plate 35. A driving motor 7 is installed on the side surface of the sealing box 1. The output shafts of the driving motor 7 are respectively drivingly connected to the first driving wheel and each second driving wheel. Specifically, a plurality of driving motors 7 can be provided, and the output shafts of each driving motor 7 are respectively drivingly connected to the corresponding first driving wheel and second driving wheel, for respectively driving the feeding conveyor belt 2 and each drying conveyor belt 3 to operate. An external hot air duct 8 is fixedly installed on the rear side of the sealing box 1. A plurality of hot air branch pipes 9 are fixedly connected to the front side surface of the external hot air duct 8. The hot air branch pipes 9 are respectively in one-to-one correspondence and communication with the inner cavities of each first drawer cabinet 24 and the inner cavity of the second drawer cabinet 34. An exhaust passage is arranged on the upper surface of the sealing box 1. The inner cavity of the sealing box 1 is communicated with the outside through the exhaust passage.

[0017] Working principle: Before use, first connect the external hot air duct 8 to a hot air blower, and the hot air blower is used to convey continuous hot air into the external hot air duct 8. In this embodiment, as Figure 2 shown, the external hot air duct 8 includes a main air duct 81 and a plurality of branch air ducts 82. The branch air ducts 82 are symmetrically installed on both sides of the main air duct 81 respectively. The hot air branch pipes 9 are fixedly connected to the front side surfaces of the respective branch air ducts 82. Among them, the outer side surface of the main air duct 81 is connected to an external hot air blower through an air inlet. A plurality of wind guiding plates can be respectively arranged inside the main air duct 81, so that the hot air flow channels inside the main air duct 81 can be evenly separated, so as to evenly flow to each branch air duct 82. And a plurality of wind guiding plates are also respectively arranged inside each branch air duct 82, so that the hot air flow channels inside each branch air duct 82 can be evenly separated, so as to evenly flow to each hot air branch pipe 9. Thus, the uniform distribution of hot air in each drawer cabinet is realized.

[0018] Then, start each driving motor 7 to drive the feeding conveyor belt 2 and each drying conveyor belt 3 to operate; and make the feeding conveyor belt 2 and a plurality of drying conveyor belts 3 cooperate to form a "Z"-shaped conveying path. The discharging conveyor belt 4 and the external conveyor belt 6 are driven to operate by their own motors.

[0019] Subsequently, during the use process, the shredded kitchen waste materials can be evenly and continuously put into the starting end of the feeding conveyor belt 2 through the feeding frame cover 5. Then, the materials gradually move forward with the transmission of the first mesh chain conveyor belt 22. During this process, the hot air conveyed by the external hot air duct 8 will enter each first drawer cabinet 24 through the hot air branch pipes 9 respectively, and then flow upward along the inner cavity of the first drawer cabinet 24 and pass through the ventilation holes of the first ventilation plate 25. Since the first mesh chain conveyor belt 22 is a mesh chain-like structure, the hot air can pass through the first mesh chain conveyor belt 22 to blow-dry the materials above it, enabling the moisture of the materials to evaporate rapidly. As the materials continue to move along the "Z" - shaped path formed by the cooperation of the feeding conveyor belt 2 and multiple drying conveyor belts 3 to the second mesh chain conveyor belt 32, at this time, hot air can be conveyed through the hot air branch pipes 9 at the rear side of the second drawer cabinet 34, and the hot air passes through the ventilation holes of the second ventilation plate 35 to further dry the materials, thereby ensuring that along the entire "Z" - shaped conveying path, through the guiding effect of each first drawer cabinet 24 and second drawer cabinet 34 on the hot air output by each hot air branch pipe 9, the materials can obtain sufficient and continuous hot air drying effect at each stage, and then effectively ensuring the drying effect of the kitchen waste.

[0020] Since the entire device stacks the feeding conveyor belt 2 and multiple drying conveyor belts 3 in an upper - lower layer and makes the feeding conveyor belt 2 and multiple drying conveyor belts 3 cooperate to form a "Z" - shaped conveying path, it greatly improves the space utilization rate, making the occupied area of the entire device very small. And through the design of the "Z" - shaped conveying path, the moving route length of the kitchen waste can be greatly increased, enabling the materials to be dried by hot air multiple times during the conveying process, ensuring that the drying effect is uniform and thorough. And it ensures that the materials can be dried evenly and continuously, meeting the requirements for large - scale kitchen waste treatment.

[0021] In this embodiment, a driving motor 7 can also be set to drive the feeding conveyor belt 2 and multiple drying conveyor belts 3 to operate respectively. Specifically, as Figure 2As shown, two drying conveyor belts 3 are provided, and the first gear 71 and the second gear 72 are fixedly installed on the end of the second transmission wheel of the drying conveyor belt 3 located at the bottom, and the third gear 73 is fixedly installed on the end of the second transmission wheel of the drying conveyor belt 3 located at the top. The fourth gear 74 is fixedly installed on the end of the first transmission wheel of the feed conveyor belt 2, and a driving gear 75 is fixedly installed on the output shaft of the driving motor 7. The driving gear 75 is connected to the first gear 71 through the first chain 76, and the second gear 72 is connected to the fourth gear 74 through the second chain 77, and the third gear 73 is located on the outside of the second chain 77 and meshes with the second chain 77. Therefore, when the output shaft of the driving motor 7 rotates forward, the first chain 76 can be used to drive the drying conveyor belt 3 located below to rotate forward. Since the second gear 72 is connected to the fourth gear 74 through the second chain 77, the drying conveyor belt 3 located below rotates forward synchronously with the feed conveyor belt 2. The third gear 73 drives the drying conveyor belt 3 located above to rotate in the opposite direction synchronously through the transmission action of the second chain 77, thereby driving the feed conveyor belt 2 and the two drying conveyor belts 3 to operate alternately, forming a stable "Z"-shaped conveying path.

[0022] In the second embodiment, as a further preferred embodiment of the first embodiment, a first guide frame 10 is provided at the output end of the feed conveyor belt 2, and the discharge end of the first guide frame 10 corresponds to the input end of the top drying conveyor belt 3. A second guide frame 11 is provided between two adjacent drying conveyor belts 3. The second guide frame 11 is fixedly mounted on the output end of the top drying conveyor belt 3, and the discharge end of the second guide frame 6 corresponds to the input end of the bottom drying conveyor belt 3. The first guide frame 10 is used to effectively guide the material, ensuring that the material on the feed conveyor belt 2 can smoothly enter the top drying conveyor belt 3. At the same time, the second guide frame 11 can accurately receive the material from the top drying conveyor belt 3 to avoid overflow, further optimizing the smooth transition of the material in the "Z"-shaped path and improving the overall drying efficiency.

[0023] In this embodiment, multiple partition plates 12 are vertically fixedly mounted on the guide planes of the first and second guide frames 10, 11. Thus, the multiple partition plates 12 form independent material channels, ensuring that the materials are not mixed during transportation. This effectively prevents material accumulation as it passes through the first and second guide frames 10, 11, and ensures that the materials are evenly dispersed into each drying conveyor belt 3, thereby ensuring that each portion of the materials is evenly heated, further improving the uniformity and thoroughness of the drying effect.

[0024] Embodiment 3, as a further preferred solution of Embodiment 1, a liquid collecting pool 13 is arranged in the inner cavity of the sealing box 1. A liquid collecting funnel 14 is fixedly installed below the input end of the feeding conveyor belt 2. One end of a conveying pipeline 15 is fixedly connected to the lower end of the liquid collecting funnel 14, and the other end of the conveying pipeline 15 corresponds to the liquid collecting pool 13. In this embodiment, the side surface of the liquid collecting funnel 14 is in sealed contact with the outer surface of the sealing box 1, so that the entire liquid collecting funnel 14 can completely cover the part of the feeding conveyor belt 2 extending out of the sealing box 1, thereby effectively preventing the liquid permeated by the materials at the input end of the feeding conveyor belt 2 from falling to the outside and causing environmental pollution. In addition, when the kitchen waste materials are put into the starting end of the feeding conveyor belt 2 through the feeding frame cover 5, part of the free liquid in the materials will seep down from the surface of the first mesh chain conveyor belt 22. At this time, the liquid collecting funnel 14 can be used to effectively collect this part of the liquid to prevent it from dripping to the ground, and the collected liquid can flow into the liquid collecting pool 13 in the sealing box 1 through the conveying pipeline 15. Therefore, through the hot air action in the sealing box 1, the liquid in the liquid collecting pool 13 can be evaporated to reduce the liquid residue, further reduce the risk of environmental pollution, and at the same time improve the overall cleanliness of the drying system.

[0025] Embodiment 4, as a further preferred solution of Embodiment 1, cleaning brush mounting seats 16 are installed inside the first conveying frame body 21 and the second conveying frame body 31. A strip-shaped cleaning brush 17 is installed above each cleaning brush mounting seat 16, and the bristles of the strip-shaped cleaning brush 17 are in contact with the surfaces of the first mesh chain conveyor belt 22 and the second mesh chain conveyor belt 32. Therefore, during the working process, when the first mesh chain conveyor belt 22 and the second mesh chain conveyor belt 32 drive the materials to move, the residual materials on the surfaces of the first mesh chain conveyor belt 22 and the second mesh chain conveyor belt 32 can be effectively cleaned by the bristles of the strip-shaped cleaning brush 17, so as to effectively prevent the residual materials from remaining on the first mesh chain conveyor belt 22 and the second mesh chain conveyor belt 32, thereby ensuring the cleanliness of the first mesh chain conveyor belt 22 and the second mesh chain conveyor belt 32, and avoiding blockage on the surfaces of the first mesh chain conveyor belt 22 and the second mesh chain conveyor belt 32 caused by the accumulation of residual materials, and further affecting the drying effect of the materials.

[0026] Embodiment 5, as a further preferred solution of Embodiment 1, a first air guide plate 18 is horizontally installed in the middle of the inner cavity of the first drawer cabinet 24. The first air guide plate 18 is arranged in a quarter-circular arc structure. The rear side of the first air guide plate 18 is fixedly installed in the middle of the rear side of the first drawer cabinet 24, and the front side of the first air guide plate 18 is installed in the middle of the upper side of the first drawer cabinet 24. Among them, an arc-shaped guide plate can be arranged at the bottom of the front side of the inner cavity of the first drawer cabinet 24 to guide the hot air to flow upward along the arc-shaped guide plate and the first air guide plate 18 respectively; a second air guide plate 19 is horizontally installed in the middle of the inner cavity of the second drawer cabinet 34. The second air guide plate 19 is arranged in a quarter-circular arc structure. The rear side of the second air guide plate 19 is fixedly installed in the middle of the rear side of the second drawer cabinet 34, and the front side of the second air guide plate 19 is installed in the middle of the upper side of the second drawer cabinet 34. Among them, an arc-shaped guide plate can be arranged at the bottom of the front side of the inner cavity of the second drawer cabinet 34 to guide the hot air to flow upward along the arc-shaped guide plate and the first air guide plate 18 respectively; the first air guide plate 18 and the second air guide plate 19 respectively divide the hot air outlets of the corresponding hot air branch pipes 9 into two air ducts.

[0027] By providing the first air guide plate 18 and the second air guide plate 19, the inner cavities of the first drawer cabinet 24 and the second drawer cabinet 34 can be effectively divided into two independent air ducts, and by dividing the hot air outlets of the hot air branch pipes 9 into two air ducts, the hot air can enter the two independent air ducts respectively, thereby ensuring that the hot air can be evenly distributed and avoiding problems such as local overheating or uneven drying caused by the concentration of hot air, and improving the overall drying efficiency.

[0028] Embodiment 6, as a further preferred solution of Embodiment 1, the feeding frame cover 5 includes a cover body 51. The cover body 51 is fixedly installed above the input end of the feeding conveyor belt 2. A plurality of feeding ports are opened on the upper surface of the cover body 51. A feeding pipe 52 is fixedly installed above the cover body 51. The lower end of the feeding pipe 52 is provided with a discharge port corresponding to the feeding port. A scraping tooth 53 is fixedly installed on the lower surface of the cover body 51. By connecting the feeding pipe 52 with the kitchen waste conveying pipeline, the kitchen waste can be conveyed to the discharge port through the feeding pipe 52, and then fall onto the upper surface of the first mesh belt conveyor 22 through the discharge port at the lower end of the discharge port. And during the process of driving the material to move forward by the first mesh belt conveyor 22, the scraping tooth 53 can be used to evenly scrape and disperse the material to ensure that the material is evenly distributed, prevent the material from piling up, and improve the drying efficiency. At the same time, the design of the feeding frame cover 5 effectively isolates the peculiar smell and ensures the cleanliness of the operation environment.
