Description

Technical Field

[0001] This utility model belongs to the field of waste pulverization, and specifically relates to a pre-pulverization structure of a kitchen waste fermentation device. Background Technology

[0002] With the acceleration of urbanization and the improvement of residents' living standards, the amount of kitchen waste generated is increasing year by year. How to efficiently and environmentally treat kitchen waste has become an important issue for urban management and environmental protection. At present, the main methods of kitchen waste treatment include landfill, incineration and resource utilization. Among them, resource utilization, especially the production of organic fertilizer or biogas through fermentation, has become a sustainable development direction. In the process of kitchen waste fermentation, pretreatment of the waste is usually required, especially crushing, to increase the specific surface area of ​​the material and improve the fermentation efficiency and uniformity. If the kitchen waste crushing equipment adopts a single crushing structure, the crushed particle size is uneven, and large pieces of material are easily not fully crushed, which affects the subsequent fermentation effect. Therefore, we hope to design a pre-crushing structure for a kitchen waste fermentation device to solve this problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pre-crushing structure for a kitchen waste fermentation device, so as to solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a pre-crushing structure for a kitchen waste fermentation device, comprising: a base, a crushing cylinder fixedly connected to the upper end of the base, and a crushing mechanism and a cleaning mechanism being provided inside the crushing cylinder;

[0005] The crushing mechanism includes a crushing shaft, with an upper crushing block and a lower crushing block fixedly sleeved at its upper and lower ends, respectively. An upper crushing blade and a lower crushing blade are integrally formed on the conical surfaces of the upper and lower crushing blocks, respectively. A crushing motor is installed at the upper end of the crushing cylinder, and the output shaft of the crushing motor is fixedly connected to the crushing shaft via a coupling. By setting up the crushing mechanism, when material enters the crushing cylinder, it first passes through the area of ​​the smaller-diameter upper crushing block. The larger primary crushing gap formed between the upper crushing block and the fixed toothed rack on the cylinder wall allows for preliminary cutting and crushing of the material. Subsequently, the material enters the area of ​​the larger-diameter lower crushing block, where the secondary crushing gap between the lower crushing block and the fixed toothed rack is smaller, allowing for tighter compression and finer shearing of the initially crushed material. This ensures that the material is fully crushed, producing material with a suitable particle size for fermentation, resulting in a more uniform and controllable crushing effect.

[0006] In a preferred embodiment, the inner wall of the crushing cylinder is integrally formed with multiple vertical fixed toothed racks in a circumferential manner, which are used to form a shearing gap with the upper and lower crushing blocks.

[0007] In a preferred embodiment, the diameter of the upper crushing block is smaller than that of the lower crushing block, which is used to form different crushing gaps with the inner wall of the crushing cylinder, thereby constituting a two-stage crushing structure.

[0008] In a preferred embodiment, a groove is provided inside the lower end of the base, and a collection chamber is slidably fitted inside the groove.

[0009] In a preferred embodiment, the lower surface of the base is provided with a rubber anti-slip pad.

[0010] In a preferred embodiment, the cleaning mechanism includes a manifold, which is fixedly fitted inside the crushing cylinder. An upper annular pipe and a lower annular pipe are fixedly connected to the upper and lower ends of the manifold, respectively. Cleaning nozzles are provided on the lower side of both the upper and lower annular pipes. By setting up the cleaning mechanism, water is pumped to the manifold and the upper and lower annular pipes, and a water curtain covering the entire inner wall of the crushing zone and the crushing components is formed by the circumferentially distributed cleaning nozzles. This can thoroughly wash away residual materials adhering to the surface of the fixed rack, crushing blocks, and crushing blades, thereby realizing automated cleaning of the inside of the crushing cylinder, providing hygiene protection for the fermentation process, and effectively ensuring the hygiene of the equipment.

[0011] In a preferred embodiment, the number of cleaning nozzles is several groups, which are evenly distributed circumferentially on the lower side of the upper and lower annular tubes.

[0012] In a preferred embodiment, a water pump is provided on the rear surface of the base, and the output end of the water pump is connected to the manifold via a flexible hose.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are:

[0014] 1. By setting up a crushing mechanism, when the material enters the crushing cylinder, it first passes through the upper crushing block area with a smaller diameter. The larger primary crushing gap formed between the upper crushing block and the fixed toothed rack on the cylinder wall can perform preliminary cutting and crushing of the material. Subsequently, the material enters the lower crushing block area with a larger diameter. The secondary crushing gap between the lower crushing block and the fixed toothed rack is smaller here, which can perform tighter compression and fine shearing on the material that has been initially crushed, thereby ensuring that the material is fully crushed and producing material with a suitable particle size for fermentation, making the crushing effect more uniform and controllable.

[0015] 2. By setting up a cleaning mechanism, water is pumped to the manifold and upper and lower annular pipes, and a water curtain is formed by the circumferentially distributed cleaning nozzles to cover the entire inner wall of the crushing zone and the crushing components. This can thoroughly wash away the residual materials attached to the fixed rack, crushing blocks and crushing blades, thereby realizing automated cleaning of the inside of the crushing cylinder and providing hygiene protection for the fermentation process.

[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 1-4 As the first embodiment of this utility model:

[0027] A pre-crushing structure for a kitchen waste fermentation device includes: a base 1, a crushing cylinder 2 fixedly connected to the upper end of the base 1, and a crushing mechanism 3 and a cleaning mechanism 4 disposed inside the crushing cylinder 2;

[0028] The crushing mechanism 3 includes a crushing shaft 31. An upper crushing block 32 and a lower crushing block 34 are fixedly sleeved at the upper and lower ends of the crushing shaft 31, respectively. An upper crushing blade 33 and a lower crushing blade 35 are integrally formed on the conical surfaces of the upper crushing block 32 and the lower crushing block 34, respectively. A crushing motor 36 is installed at the upper end of the crushing cylinder 2. The output shaft of the crushing motor 36 is fixedly connected to the crushing shaft 31 via a coupling. By setting up the crushing mechanism 3, when material enters the crushing cylinder 2, it first passes through the area of ​​the smaller-diameter upper crushing block 32. The larger primary crushing gap formed between the upper crushing block 32 and the fixed toothed rack on the cylinder wall allows for preliminary cutting and crushing of the material. Subsequently, the material enters the area of ​​the larger-diameter lower crushing block 34. Here, the secondary crushing gap between the lower crushing block 34 and the fixed toothed rack is smaller, allowing for tighter compression and finer shearing of the initially crushed material. This ensures that the material is fully crushed, producing material with a suitable particle size for fermentation, resulting in a more uniform and controllable crushing effect.

[0029] The inner wall of the crushing cylinder 2 is integrally formed with multiple vertical fixed toothed bars, which are used to form a shearing gap with the upper crushing block 32 and the lower crushing block 34.

[0030] The upper crushing block 32 has a smaller diameter than the lower crushing block 34, which is used to form different crushing gaps with the inner wall of the crushing cylinder 2, thereby constituting a two-stage crushing structure.

[0031] The lower end of the base 1 has a groove, and the collection chamber 11 is slidably fitted inside the groove.

[0032] The lower surface of the base 1 is provided with a rubber anti-slip pad 12.

[0033] Specifically, by starting the crushing motor 36, the crushing motor 36 drives the crushing shaft 31 to rotate at high speed through the coupling, thereby causing the upper crushing block 32 and the lower crushing block 34, which are fixedly sleeved on the shaft, to rotate together. The integrated upper crushing blade 33 and lower crushing blade 35 on the conical surfaces of the upper crushing block 32 and the lower crushing block 34 rotate at high speed accordingly. The inclined conical surfaces of the conical upper crushing block 32 and the lower crushing block 34 can effectively guide the material, prevent it from accumulating at the inlet, and ensure that the material enters smoothly and moves downward. Then, during the rotation, the material first enters the area of ​​the upper crushing block 32. Since the upper crushing block 32 has a small diameter, it is close to the inner wall of the crushing cylinder 2. A large primary crushing gap is formed between the circumferential fixed racks, which performs preliminary cutting and crushing of the material. Subsequently, the initially crushed material falls into the area of ​​the lower crushing block 34. At this time, the lower crushing block 34 has a larger diameter and a smaller secondary crushing gap with the fixed racks. In this area, the material is subjected to tighter compression and finer shearing, and is finally crushed to the target particle size. This two-stage crushing structure, which is from top to bottom and the gap decreases from large to small, significantly improves the crushing efficiency and effect. Finally, this pre-crushing structure serves as the pretreatment section of the kitchen waste fermentation device. Its discharge port is collected by the collection bin and then indirectly transported to the fermentation tank for fermentation reaction.

[0034] Please see Figure 1 as well as Figure 4 As a second embodiment of this utility model:

[0035] The cleaning mechanism 4 includes a manifold 41, which is fixedly fitted inside the crushing cylinder 2. The upper and lower ends of the manifold 41 are respectively fixedly connected to an upper annular pipe 42 and a lower annular pipe 43. Cleaning nozzles 44 are provided on the lower side of both the upper annular pipe 42 and the lower annular pipe 43. By setting up the cleaning mechanism 4, water is delivered to the manifold 41 and the upper and lower annular pipes 43 by a water pump 45. The water curtain covering the entire inner wall of the crushing zone and the crushing components is formed by the circumferentially distributed cleaning nozzles 44. This can thoroughly wash away the residual materials attached to the fixed rack, crushing blocks and crushing blades, thereby realizing the automated cleaning of the inside of the crushing cylinder 2, providing a hygienic guarantee for the fermentation process and effectively ensuring the hygiene of the equipment.

[0036] The number of cleaning nozzles 44 is several groups, which are evenly distributed in a circle on the lower side of the upper annular tube 42 and the lower annular tube 43.

[0037] A water pump 45 is provided on the rear surface of the base 1, and the output end of the water pump 45 is connected to the manifold 41 through a flexible hose.

[0038] Based on the above embodiments, after the water pump 45 is started, the water flow is pumped through the hose into the manifold 41 fixed inside the cylinder. The manifold 41 delivers the water to the upper and lower annular pipes respectively. Since the lower side of the upper annular pipe 42 and the lower annular pipe 43 are both circumferentially distributed with several cleaning nozzles 44, the water flow is sprayed out at high speed from these nozzles to form a water curtain covering the inner wall of the crushing cylinder 2 and the upper crushing block 32 and the lower crushing block 34. These water curtains can effectively wash away the residual materials attached to the fixed rack, crushing block and crushing blade surface. The washed sewage and impurities fall under the action of gravity and are finally discharged through the base 1, thereby realizing the automated cleaning of the inside of the crushing cylinder 2.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
