Description

Technical Field

[0001] The utility model relates to the technical field of comprehensive utilization of agricultural wastes, in particular to a device for resource conversion of agricultural wastes and comprehensive utilization of fermentation products thereof. Background Art

[0002] With the progress of society and the acceleration of enterprise production, more and more solid waste is generated. The traditional way to deal with solid waste is through landfill and stacking, which seriously occupies land resources and pollutes the ecological environment. At present, solid waste can be fermented through biotechnology to achieve the purpose of solid waste resource utilization.

[0003] As disclosed in Chinese patent announcement No. CN219043552U, a solid waste resource comprehensive utilization and treatment device is disclosed. When in use, the material is crushed by the crushing box and then enters the fermentation box from the feed pipe for fermentation. During fermentation, the output end of the rotating motor drives the stirring shaft to rotate, and the stirring shaft drives the stirring teeth to rotate, thereby stirring the material. After the material is fermented, gas is generated, and the gas enters the dehumidification box through the air inlet pipe. The activated carbon bag in the dehumidification box absorbs water vapor in the gas, so that the dry gas enters the gas storage tank through the air outlet pipe. On the other hand, the stirring shaft drives the first bevel gear to rotate, and the first bevel gear drives the second bevel gear meshing with it to rotate, and the second bevel gear drives the transmission rod to rotate. The transmission rod drives the support rod to rotate through the cooperation of the card bar and the card slot, thereby driving the activated carbon bag to rotate, so as to increase the contact area between the activated carbon bag and the gas.

[0004] However, the solid waste resource comprehensive utilization and treatment device in the above application has certain limitations. After stirring the materials, waste will remain on the crushing box and the stirring shaft, which may cause rust over a long period of time and affect subsequent use.

[0005] Therefore, we urgently need to provide a device for the resource utilization of agricultural waste and the comprehensive utilization of its fermentation products. Utility Model Content

[0006] The purpose of the utility model is to provide a device for the resource recovery of agricultural waste and the comprehensive utilization of its fermentation products, so as to solve the problem that after the material is stirred in the solid waste resource recovery and comprehensive utilization treatment device, waste will remain on the crushing box and the stirring shaft, which may cause rust over a long period of time and affect subsequent use.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for the resource utilization of agricultural waste and its fermentation products, comprising a crushing tank and a base, wherein the two bases are respectively fixedly connected to the left and right sides of the bottom of the crushing tank, and a crushing and stirring device is arranged inside the crushing tank.

[0008] The crushing and stirring device comprises a crushing unit, a scraping unit and a cleaning unit.

[0009] The crushing unit includes a crushing motor, a sealed bearing, a stirring shaft, and a stirring auger. The crushing motor is installed on the right outer surface of the crushing tank through a mounting plate. The two sealed bearings are respectively installed at the center of the left and right outer surfaces of the crushing tank. The stirring shaft is connected to the output end of the crushing motor, and its two ends are rotatably connected to the inside of the sealed bearings. The stirring auger is fixedly connected to the outer surface of the stirring shaft. Starting the crushing motor drives the stirring shaft to rotate inside the sealed bearing, thereby driving the stirring auger on its outer surface to rotate, so as to crush and stir the waste, so that the waste is fully mixed to facilitate subsequent fermentation.

[0010] A further improvement is that the scraper unit includes a connecting rod, a buffer assembly, and a scraper plate. The two connecting rods are respectively fixedly connected to the left and right outer surfaces of the stirring shaft, and the two groups of buffer assemblies are respectively installed on the outer ends of the connecting rods. The scraper plate is fixedly connected to the outer ends of the buffer assemblies. When the stirring shaft rotates, the connecting rod is driven to rotate, so that the scraper plate at its outer end is driven by the buffer assembly to scrape off the waste adhered to the inner wall of the crushing tank, thereby preventing a large amount of waste from adhering to the inner wall of the crushing tank and corroding it.

[0011] A further improvement is that the buffer assembly includes a mounting groove, a flexible spring, and a sliding rod, the mounting groove is opened inside the outer end of the connecting rod, the flexible spring is installed inside the mounting groove, the sliding rod is fixedly connected to the outer end of the flexible spring, and is slidably connected to the inside of the mounting groove, and its outer end is fixedly connected to the scraper plate. When the scraper plate rotates to scrape the inner wall of the crushing tank, the force generated by the contact between the two pushes the sliding rod to slide into the inside of the mounting groove and squeeze the flexible spring, thereby utilizing the elasticity of the flexible spring to buffer the impact force and avoid hard contact between the two, which may cause the scraper plate to break or the inner wall to be scratched.

[0012] A further improvement is that the cleaning unit includes an installation box, a water inlet pipe, a water distribution pipe, and a high-pressure nozzle. The installation box is fixedly connected to the top of the crushing tank, the water inlet pipe extends into the interior of the installation box, the water distribution pipe is fixedly connected to the bottom of the water inlet pipe, and a plurality of high-pressure nozzles are horizontally and equidistantly fixedly connected to the bottom of the water distribution pipe. After the waste is crushed, stirred and transported, clean water is poured into the interior of the water distribution pipe through the water inlet pipe and sprayed out through the high-pressure nozzle, thereby flushing the inner wall of the crushing tank and its internal structure to prevent it from being corroded by the waste, thereby increasing the service life of the device. Diluting the waste with water is more conducive to its fermentation.

[0013] A further improvement is that a feed pipe is fixedly connected to the right side of the top of the crushing tank, and a discharge pipe is fixedly connected to the bottom of the left outer surface of the crushing tank. An electric sealing valve is installed on the outer surface of the discharge pipe. The waste is introduced into the interior of the crushing tank through the feed pipe. After the waste is mixed, the electric sealing valve is started to discharge the waste through the discharge pipe for fermentation.

[0014] A further improvement is that a fermentation box is placed on the left side of the crushing tank, and the discharge pipe extends into the interior of the fermentation box. A gas pipe is fixedly connected to the top of the fermentation box. The waste falling into the fermentation box is fermented and the biogas generated is discharged through the gas pipe, so that resources are reused for the second time, thereby improving resource utilization.

[0015] A further improvement is that a sealed door is installed on the front of the fermentation box through a hinge, and an observation window is installed on the front of the sealed door. The waste capacity inside the fermentation box can be observed in real time through the observation window. When there is too much waste, the sealed door can be opened to take out part of the fermented waste.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The device for comprehensive utilization of agricultural waste resources and fermentation products starts the crushing motor to drive the stirring shaft to rotate inside the sealed bearing, thereby driving the stirring auger on its outer surface to rotate, to crush and stir the waste, so that the waste is fully mixed to facilitate subsequent fermentation.

[0018] 2. The device for comprehensive utilization of agricultural waste resources and fermentation products drives the connecting rod to rotate while the stirring shaft rotates, thereby driving the scraper plate at its outer end to scrape off the waste adhered to the inner wall of the crushing tank through the buffer component, thereby preventing a large amount of waste from adhering to the inner wall of the crushing tank and corroding it.

[0019] 3. In the device for comprehensive utilization of agricultural waste resources and fermentation products, when the scraper plate rotates to scrape the inner wall of the crushing tank, the force generated by the contact between the two pushes the slide bar to slide into the inside of the installation groove and squeeze the flexible spring, thereby utilizing the elasticity of the flexible spring to buffer the impact force and avoid hard contact between the two, which may cause the scraper plate to break or the inner wall to be scratched.

[0020] 4. The device for comprehensive utilization of agricultural waste resources and fermentation products, after the waste is crushed, stirred and transported, clean water is poured into the water distribution pipe through the water inlet pipe and sprayed out through the high-pressure nozzle, thereby flushing the inner wall of the crushing tank and its internal structure to prevent it from being corroded by the waste, thereby increasing the service life of the device, and diluting the waste with water is more conducive to its fermentation.
