Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fruit and vegetable waste treatment technology, and in particular relates to a device for extruding and dehydrating fruit and vegetable waste. Background Technology
[0002] When processing fruit and vegetable waste, the water content is typically above 70%. This high moisture content not only slows down the decomposition process during natural composting but also easily produces foul odors and occupies a significant amount of landfill space. Therefore, dehydration treatment of fruit and vegetable waste is necessary. First, dehydration significantly reduces the volume and weight of the waste, helping to reduce transportation and storage costs. Dehydration uses physical methods (such as screw extrusion) to squeeze out the water from the waste, thereby reducing its moisture content. The volume of dehydrated fruit and vegetable waste can be reduced to a very small percentage of its original size, greatly improving waste treatment efficiency. Second, fruit and vegetable waste easily ferments and produces foul odors under natural conditions, while dehydration significantly reduces its moisture content, slowing down the fermentation process and reducing odor production. This is of great significance for improving urban environmental sanitation and enhancing the quality of life for residents. Finally, dehydrated fruit and vegetable waste has a higher solids content, making it easier for subsequent resource utilization. For example, dehydrated fruit and vegetable waste can be used as a substrate for organic fertilizer or as a raw material for biomass fuel. This not only helps to achieve the recycling of resources, but also reduces dependence on traditional energy sources.
[0003] However, existing technologies have some problems: when processing fruit and vegetable waste, because fruit and vegetable waste usually contains large lumps or strips of material, and even carries some plastic parts, these materials may entangle or block the equipment during the processing, resulting in reduced processing efficiency. In addition, if the fruit and vegetable waste contains a lot of fiber, peels, seeds and other impurities during the extrusion process, they will accumulate at the extrusion holes and cause blockage, increasing the risk of blockage. Therefore, we propose an extrusion dehydration device for processing fruit and vegetable waste. Utility Model Content
[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a device for extruding and dehydrating fruit and vegetable waste. By setting up a linked crushing component, the fruit and vegetable waste is crushed and continuously fed into the extrusion tank, reducing the discharge pressure. Furthermore, the spiral blades rotate continuously to prevent the discharge from accumulating and causing blockages.
[0005] This utility model is implemented as follows: a device for dehydrating and squeezing fruit and vegetable waste includes a tank body with an inner cavity. A drain pipe is provided at the lower end of the tank body. A connecting seat is fixedly connected to the tank body. A squeezing tank is provided at the lower end of the connecting seat.

A discharge pipe is provided at the lower end of the squeezing tank. A feeding component is provided on the outer side of the tank body and is connected to the feed pipe.
[0006] Optionally, the discharge pipe passes through the tank body, and a material guiding component is provided inside the discharge pipe to break up the extruded residue.
[0007] Optionally, an annular pipe is provided on the outside of the extrusion tank, a water spray head is provided at the lower end of the annular pipe, the water spray head is inclined, and a water inlet pipe is provided at the upper end of the annular pipe.

[0009] Optionally, the pressure component is slidably connected to the extrusion tank, and the pressure component is correspondingly arranged with the extrusion tank.
[0010] Optionally, the feeding assembly includes a feed inlet and a feeding pipe, the feed inlet is fixedly connected to the feeding pipe, the feed inlet communicates with the feeding pipe, the feeding pipe is fixedly connected to the feed pipe, and a one-way valve is provided on the feed pipe.
[0011] Optionally, a motor is provided on the feed inlet, and a crushing roller is provided in the feed inlet. The output end of the motor is fixedly connected to the crushing roller, and there are two crushing rollers that mesh with each other.
[0012] Optionally, a drive wheel is fixedly connected to the crushing roller, a driven wheel is provided on the outside of the feed inlet, the drive wheel meshes with the driven wheel, a pulley is provided on the driven wheel, a synchronous wheel shaft is rotatably connected to the feeding pipe, the pulley and the synchronous wheel shaft rotate synchronously through a belt, and a helical blade is provided on the outside of the synchronous wheel shaft.
[0013] Optionally, the material guiding assembly includes a discharge plate, a screw, and a rotating shaft. The discharge plate is fixedly connected to the extrusion tank, and a discharge hole and an installation groove are provided on the discharge plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. By setting up a feeding component, when fruit and vegetable waste is fed, the waste is first crushed and then enters the feeding pipe. It is continuously fed into the compression tank by the spiral blades on the synchronous wheel shaft. Smaller waste particles are more easily and evenly distributed in the equipment, which facilitates compression processing and reduces the risk of clogging of the discharge hole.
[0017] 2. By setting up a material guiding component, when the pressure component is pressed down, it synchronously drives the screw to move down, which in turn drives the support rod on the rotating shaft to rotate. During the rotation process, the spiral support rod can effectively break up the slag extruded from the discharge hole, destroy the blocky structure in the slag, and make it more loose and fine, thereby reducing the risk of blockage. In addition, the broken slag has better fluidity, reducing the residue formed in and around the discharge hole, thereby reducing the risk of blockage.
[0018] 3. By installing a ring-shaped pipe, the nozzles on the pipe can spray water or other cleaning media into the orifices on the outside of the extrusion tank, directly flushing away impurities, residues, or blockages adhering to the orifices. This direct cleaning method ensures that the orifices remain unobstructed, preventing equipment malfunctions or performance degradation due to blockages. Compared to traditional cleaning methods, cleaning using nozzles on the ring-shaped pipe is more efficient. The nozzles can evenly spray the cleaning media, ensuring that each orifice is thoroughly cleaned.

[0028] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0029] like Figures 1 to 7 As shown in the figure, the present invention provides a device for dehydrating and squeezing fruit and vegetable waste, which includes a tank body 1. The tank body 1 has an inner cavity 11. A drain pipe 12 is provided at the lower end of the tank body 1. A connecting seat 13 is fixedly connected to the tank body 1. A squeezing tank 14 is provided at the lower end of the connecting seat 13. A pressing component 2 is provided on the connecting seat 13. A feed pipe 17 is provided at the lower end of the squeezing tank 14. A seepage hole 16 is opened on the outer side of the squeezing tank 14. A discharge pipe 15 is provided at the lower end of the squeezing tank 14. A feeding component 3 is provided on the outer side of the tank body 1. The feeding component 3 is connected to the feed pipe 17.
[0030] Furthermore, firstly, the combined use of tank 1 and compression tank 14 effectively compresses and dehydrates fruit and vegetable waste, significantly reducing its volume and weight, facilitating subsequent processing and transportation. Secondly, the drainage holes 16 allow excess water generated during the compression process to drain promptly, preventing water accumulation inside the waste. Simultaneously, the automated operation of the feeding assembly 3 and the pressing assembly 2 improves processing efficiency and reduces labor costs.
[0031] Specifically, the discharge pipe 15 passes through the tank body 1, and the discharge pipe 15 is equipped with a material guiding component 4, which is used to break up the extruded material residue.
[0032] Furthermore, this component effectively disperses the extruded material residue, preventing it from clogging the discharge pipe 15 and ensuring smooth discharge. This not only improves the processing efficiency of the device but also avoids downtime maintenance and cleaning costs caused by blockages. At the same time, the dispersing effect of the material guiding component 4 helps to distribute the residue evenly, providing better raw material conditions for subsequent processing steps (such as composting or anaerobic digestion).
[0033] Specifically, an annular pipe 19 is provided on the outside of the extrusion tank 14, a water spray head 1901 is provided at the lower end of the annular pipe 19, the water spray head 1901 is inclined, and a water inlet pipe 1902 is provided at the upper end of the annular pipe 19.
[0034] Furthermore, by installing the annular pipe 19, the nozzles on the annular pipe 19 can spray water or other cleaning media into the holes on the outside of the extrusion tank 14, directly flushing away impurities, residues, or blockages attached to the orifices. This direct cleaning method ensures that the orifices remain unobstructed, avoiding equipment malfunctions or performance degradation due to blockages. Compared to traditional cleaning methods, cleaning using the nozzles on the annular pipe 19 is more efficient. The nozzles can evenly spray the cleaning media, ensuring that each orifice is thoroughly cleaned.
[0035] Specifically, the pressing assembly 2 includes a hydraulic rod 23, a guide rod 21 fixedly connected to the connecting seat 13, a mounting plate 22 fixedly connected to the guide rod 21, the hydraulic rod 23 fixedly connected to the mounting plate 22, a pressure component 24 fixedly connected to the output end of the hydraulic rod 23, the pressure component 24 slidably connected to the extrusion tank 14, and the pressure component 24 and the extrusion tank 14 are correspondingly arranged.
[0036] Furthermore, the hydraulic rod 23, acting as a power source, is fixedly connected to the guide rod 21 via the mounting plate 22, enabling stable transmission of pressure to the pressure component 24. This allows for uniform pressing of the fruit and vegetable waste within the compression tank 14, improving pressing efficiency and ensuring pressing stability, thus preventing equipment damage or poor processing results caused by uneven pressure. Simultaneously, the telescopic nature of the hydraulic rod 23 makes the pressing process more flexible and controllable, allowing adjustment of the pressing force according to actual needs, thereby meeting the processing requirements of different fruit and vegetable wastes.
[0037] Specifically, the feeding assembly 3 includes a feed inlet 31 and a feeding pipe 38. The feed inlet 31 is fixedly connected to the feeding pipe 38 and communicates with the feeding pipe 38. The feeding pipe 38 is fixedly connected to the feed pipe 17 and a one-way valve 18 is provided on the feed pipe 17.
[0038] Furthermore, by fixing the feed inlet 31 to the feeding pipe 38 and ensuring their connectivity, the fruit and vegetable waste can be smoothly fed into the feeding pipe 38 and then into the extrusion tank 14 for processing. The one-way valve 18 installed on the feed pipe 17 plays a crucial role. It prevents backflow of materials during the feeding process, ensuring the continuity and stability of the feeding, improving feeding efficiency, and avoiding equipment failure or poor processing results caused by material backflow. This enhances the practicality and reliability of the entire fruit and vegetable waste processing extrusion and dewatering device.
[0039] Specifically, a motor 32 is installed on the feed inlet 31, and a crushing roller 33 is installed in the feed inlet 31. The output end of the motor 32 is fixedly connected to the crushing roller 33. There are two crushing rollers 33, and the two crushing rollers 33 mesh with each other. A drive wheel 34 is fixedly connected to the crushing roller 33. A driven wheel 35 is installed on the outside of the feed inlet 31. The drive wheel 34 meshes with the driven wheel 35. A pulley 36 is installed on the driven wheel 35. A synchronous pulley shaft 37 is rotatably connected to the feeding pipe 38. The pulley 36 and the synchronous pulley shaft 37 rotate synchronously through a belt. A spiral blade 39 is installed on the outside of the synchronous pulley shaft 37.
[0040] Furthermore, firstly, the motor 32 drives the crushing roller 33 to rotate, which can effectively crush the fruit and vegetable waste and improve the efficiency of subsequent extrusion and dehydration; secondly, the meshing design of the two crushing rollers 33 ensures the uniformity and fineness of crushing and reduces the risk of clogging; thirdly, the meshing of the drive wheel 34 and the driven wheel 35 and the synchronous rotation of the belt pulley 36 and the synchronous shaft 37 realize the efficient transmission of power, which enables the spiral blades 39 to rotate stably, further pushing the crushed fruit and vegetable waste into the extrusion tank 14, improving the continuity and automation of the entire processing process, improving processing efficiency, and ensuring the stability and durability of the equipment.
[0041] Specifically, the material guiding assembly 4 includes a discharge plate 41, a screw 44, and a rotating shaft 45. The discharge plate 41 is fixedly connected to the extrusion tank 14. The discharge plate 41 has a discharge hole 42 and an installation groove 43. The screw 44 is fixedly connected to the pressure component 24. The rotating shaft 45 is rotatably connected to the installation groove 43. The screw 44 and the rotating shaft 45 are threadedly connected. A support rod 46 is fixedly connected to the outer side of the rotating shaft 45. A sealing ring 47 and a sealing gasket 48 are provided in the installation groove 43.
[0042] Furthermore, firstly, the fixed connection between the discharge plate 41 and the extrusion tank 14 ensures the stability of the discharge, while the discharge hole 42 allows the slag to be discharged smoothly. The fixed connection between the screw 44 and the pressure component 24, as well as the threaded connection between the screw 44 and the rotating shaft 45, effectively disperses and pushes the slag, avoiding clogging problems. At the same time, the support rod 46 on the outside of the rotating shaft 45 enhances its stability, ensuring the smoothness of the screw 44 during rotation. In addition, the sealing ring 47 and sealing gasket 48 in the mounting groove 43 effectively prevent material leakage, improving the sealing performance and cleanliness of the equipment.
[0043] Working principle: When fruit and vegetable waste is fed, it is first crushed and then enters the feeding pipe 38. It is continuously fed into the extrusion tank 14 by the spiral blades 39 on the synchronous wheel shaft 37. The hydraulic rod 23 drives the pressure component 24 to extrude and dehydrate the fruit and vegetable waste. Then, some of the residue is discharged through the discharge hole 42. When the pressure component 24 is pressed down, it presses the cover plate inside the one-way valve 18 to prevent the waste from being continuously output. When the pressure component 24 is lifted, the waste pushes open the cover plate and continues to be input. When the pressure component 24 is pressed down, it synchronously drives the screw 44 to move down, which drives the support rod 46 on the rotating shaft 45 to rotate. During the rotation, the spiral support rod 46 can effectively break up the residue squeezed out from the discharge hole 42, destroy the block structure in the residue, and make it looser and finer, thereby reducing the risk of blockage. In addition, the broken residue has better fluidity, reducing the residue formed in and around the discharge hole 42, thereby reducing the risk of blockage.
[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
