[0034] In this embodiment, Figure 5 As shown, both ends of the door plate 401 are respectively provided with slots for being inserted and connected to the corresponding slots on one side of the outer wall of the sedimentation box 4, and the door plate 401 forms an opening and closing structure on one side of the sedimentation box 4, and the surface of the tenon 405 is penetrated by a threaded slot and the surface of the tenon groove 406 is not penetrated by a threaded slot, and the tenon 405 and the tenon groove 406 are connected by bolts; the position distribution of the sedimentation box 4 can collect the sediment precipitated inside even when the cleaning barrel 2 is in operation, without stopping the processing process, which undoubtedly improves the work efficiency for the cleaning work, and at the same time The combination of the opening and closing door panel 401 and its internal sloping bottom surface provides powerful and convenient conditions for extracting the sediment deposited inside, and the plug-in structure of the door panel 401 and the sedimentation box 4 improves the tightness of the connection between the two, thereby achieving sealing, and the external tenon 405 and the tenon groove 406 are connected again by bolts to further increase the stability of the connection between the two. At the same time, the first rubber pad 403 and the second rubber pad 404 respectively provide further advantages for strengthening the sealing, effectively avoiding the problem of leakage of medium and sediment from the connection.

[0035] In this embodiment, Figure 5 and Figure 6 As shown, the bottom of the sedimentation box 4 is in the shape of an inclined slope, and the baffle plate 407 is located at a lower position on one side of the slope, and the water inlet on one side of the filter box 5 is located on one side of the pp cotton filter plate 502 and is connected to the pipe port at one end of the baffle plate 407 through a pipe, and the water outlet on one side of the filter box 5 is located on one side of the activated carbon filter plate 503 and is connected to the reflux box 6 through a pipe; the baffle plate 407 can effectively prevent sediment from flowing into the interior of the filter box 5, saving maintenance costs, and greatly reducing the replacement cycle of the pp cotton filter plate 502 and the activated carbon filter plate 503. At the same time, the plug-in structure of the pp cotton filter plate 502 and the activated carbon filter plate 503 is also easy to replace, and the medium is processed in sequence, which can effectively absorb organic matter, impurities and odors in the medium, so that the water quality that finally flows into the reflux box 6 is purer, thereby making the water quality of the circulating water after filtration relatively stable, ensuring the continuity of the cleaning work and saving water costs, and effectively avoiding the waste of water resources and pollution emissions.

[0036] The use method and advantages of the utility model: When the raw material cleaning device with a water circulation structure is used, the working process is as follows:

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, it should be noted that the sedimentation box 4 is connected to the filter box 5 through a centrifugal pump, one side of the filter box 5 is connected to the reflux box 6 through a centrifugal pump, and the reflux box 6 is connected to the cleaning barrel 2 through a water pump, and in order to avoid backflow of the medium, a one-way valve is provided at one end of the pipeline. When feeding for the first time, the handle on the top of the barrel cover 3 is pulled to rotate it toward the side opposite to the limit plate 202 and rotate it to 180° to prevent the raw materials from being inside the cleaning barrel 2, and then clean water for cleaning the raw materials is injected into it, and the barrel cover 3 is rotated again to reset, rotate and fit to one end of the limit plate 202, and the cleaning barrel 2 is connected to the threaded opening on the surface of the barrel cover 3 by bolts to fix the two. After turning on the power, the incomplete gear 204 is driven by the servo motor The machine rotates, and when the side with serrations on its surface meshes with the side of the gear 203 during the rotation process, it will drive the transmission of the gear 203 and then rotate the internal stirring shaft 205. The serration structure of the incomplete gear 204 with equiangular distribution is used to achieve the purpose of intermittent rotation of the stirring shaft 205, and the structural form of the stirring shaft 205 can increase the turbulence of the water flow inside the cleaning barrel 2, so that the medium can more fully contact the surface of the raw material, and effectively wash away the mud and sand on the surface of the raw material. In the process of cleaning, the ultraviolet disinfection lamp 301 under the barrel cover 3 can be used for simultaneous disinfection, which can effectively kill bacteria on the surface of the raw material. The physical disinfection method is used to remove microorganisms on the surface of the raw material. Compared with chemical disinfection, the purity of the raw material is guaranteed, and its surface The protective cover 302 is made of quartz glass, which can protect it without affecting the irradiation effect. The processing personnel can observe the turbidity of the internal water according to the observation port 206. If the water quality is turbid, the valve of the external pipe 201 can be opened. The knife gate valve (model PZ673H-10C / 10P) is driven by a pneumatic structure to realize the opening and closing of the valve. The gate is perpendicular to the flow direction of the fluid, cutting off the fluid channel, and has good sealing performance. The efficient flowability can help to ensure that the internal sediment is discharged into the sedimentation box 4 along with the medium. Due to the structure of the baffle plate 407, the medium will flow into the interior of the filter box 5 through the pipeline and the pump body, while the sediment will be retained in the sedimentation box 4 and converge into its lowest point of inclination and the sealing partition 4 under flushing. 02, and after the medium passes through the surfaces of the pp cotton filter plate 502 and the activated carbon filter plate 503 respectively, the microorganisms and impurities in the medium will be retained on their surfaces respectively, and the clean water after filtration will flow through the pump body to the reflux box 6 and return to the inside of the cleaning barrel 2 again. If it is necessary to extract the sediment inside the sedimentation box 4, remove the bolts connecting the tenon 405 and the tenon groove 406, and after turning over the door panel 401, grab the top of the sealing partition 402 and take it out from the groove of the sedimentation box 4, and the sediment at the front end can be extracted. At the same time, it should be noted that the spacing distance between the bottom of the cleaning barrel 2 and the sedimentation box 4 and the filter box 5 meets the disassembly conditions of the sealing partition 402, the pp cotton filter plate 502 and the activated carbon filter plate 503.
