Further, the first wave overturning filtering mechanism 4 and the second wave overturning filtering mechanism 5 arranged in the cleaning tank 1 can form a wave overturning effect on the water in the tank during the cleaning process of the soybean, the generated waves repeatedly flush the soybean in the tank, the flushing force acts on the soybean, the dirt, dust and other impurities on the surface of the soybean can be more effectively removed, and the surface dirt is accelerated to be removed; and the wave overturning mechanism can also timely discharge the dirt cleaned and washed out of the cleaning tank 1, so that the dirt is avoided from being brought into the next process due to residual dirt.

[0026] Embodiment 2

[0027] The embodiment discloses a raw material washing machine for producing douchi, and refers to the drawings in the specification Figure 1 On the basis of embodiment 1, at least one first wave overturning filtering mechanism 4 is arranged in the first cleaning section 2; and at least one second wave overturning filtering mechanism 5 is arranged in the second cleaning section 3.

[0028] Embodiment 3

[0029] The embodiment discloses a raw material washing machine for producing douchi, and on the basis of embodiment 1, the structure of the first wave overturning filtering mechanism 4 and the second wave overturning filtering mechanism 5 is specifically limited and explained, and the specific implementation is as follows.

[0030] The drawings in the specification Figure 1 As shown in the drawings in the specification, the first wave overturning filtering mechanism 4 is arranged at the bottom of the cleaning tank 1 and comprises a first sedimentation hopper 401 and a first filter plate 402. The bottom of the cleaning tank 1 is provided with a first opening, the first sedimentation hopper 401 is installed at the first opening and covers the first opening, a first dirt discharge pipe is arranged at the outlet of the first sedimentation hopper 401, and a dirt discharge valve is arranged in the first dirt discharge pipe. The first filter plate 402 is installed in the first sedimentation hopper 401 and the installation height of the first filter plate 402 is slightly lower than the first opening, so that the first filter plate 402 and the hopper wall of the first sedimentation hopper 401 form a first sedimentation groove 6 in a sinking mode at the first opening.

[0031] In the embodiment depicted in the utility model, since the first sedimentation groove 6 is a sunken structure, the first filter plate 402 and the first opening of the groove body are not flush, so when the water body passes through the first sedimentation groove 6, the groove wall of the first sedimentation groove 6 will form a wave effect on the flowing water body, the water body will generate waves opposite to the conveying direction, and the waves repeatedly scour the soybeans in the groove body, so that the dirt, dust and other foreign matters and impurities on the surface of the soybeans can be removed more effectively. The impurities scoured down leak from the filter holes on the first filter plate 402 and are filtered into the first sedimentation hopper 401.

[0032] It should be noted that the first filter plate 402 is only slightly lower than the height of the first opening and is installed in the first sedimentation hopper 401, so that the sunken depth of the first sedimentation groove 6 formed is very shallow, and the purpose is to form a wave effect on the water body, but will not block the movement of the soybeans in the cleaning groove body along the conveying direction, so as to ensure that the soybeans are smoothly conveyed to the next process.

[0033] Further, continuing to refer to the drawings Figure 1 As shown in the drawings, the second wave overturning and filtering mechanism 5 is arranged at the bottom of the cleaning groove body 1 and comprises two second sedimentation hoppers 501 arranged along the conveying direction, two second openings are correspondingly arranged at the bottom of the cleaning groove body 1, the two second sedimentation hoppers 501 are respectively installed at the two second openings and cover the two second openings respectively, and a second sewage pipe is arranged at the outlet of the second sedimentation hopper 501, and a sewage valve is also arranged in the second sewage pipe; further, the two second sedimentation hoppers 501 are respectively provided with inclined second filter plates 502, wherein the inclined direction of the second filter plate 502 located in front is inclined forward along the material conveying direction, the inclined direction of the second filter plate 502 located in back is inclined backward against the material conveying direction, and the inclined directions of the two second filter plates 502 are symmetrical.

[0034] In the embodiment depicted in the utility model, when the water body passes through the second wave overturning and filtering mechanism 5, a good wave effect will be formed between the two second filter plates 502, and the water body generates reciprocating waves between the two. Therefore, when the soybeans move to the second wave overturning and filtering mechanism 5, the waves generated at this position repeatedly scour the soybeans in the groove body, so that the dirt, dust and other foreign matters and impurities on the surface of the soybeans can be removed more effectively. Further, the impurities scoured down leak from the filter holes on the second filter plate 502 and are filtered into the second sedimentation hopper 501.

[0035] At this point, the soybeans in the cleaning groove body 1 are sent to the next process after at least twice of wave cleaning, the soybean cleaning effect is good, and the processing and production quality of the subsequent products is ensured. After cleaning is completed, the sewage valve is opened, and the dirt, impurities and the like in the sedimentation hopper are discharged and cleaned through the sewage pipe.

[0036] It should be noted that the second filter plate 502 is also slightly lower than the height of the second opening installed in the second hopper 451, while realizing the water body overturning, without blocking the soybeans in the cleaning tank 1 along the conveying direction, to ensure that the soybeans are smoothly conveyed to the next process.

[0037] In the embodiment described in the present application, it can be understood that the second overturning and filtering mechanism 5 uses two second filter plates 502 in cooperation to achieve better overturning effect.
