Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0021] As Figures 1 to 2 shown, in this embodiment, the following problems exist in the prior art: The inventor found the following defects in the prior art: First, when starting the filter, soy sauce is directly discharged into the filter and impacts the filter membrane. Long-term impact will reduce the service life of the filter membrane and increase production costs; Second, impurities are likely to accumulate on the surface of the filter membrane, reducing the filtration efficiency of the filter membrane;

[0022] Therefore, the inventor provides a filter for soy sauce processing, including a box body and a filtering device. The filtering device is arranged in the middle of the box body; The box body further includes a feed inlet 1, a buffer chamber 2, a filtration chamber 3, and a discharge outlet 4. The feed inlet 1 is arranged above the buffer chamber 2, the buffer chamber 2 is arranged above the filtration chamber 3, and the discharge outlet 4 is arranged below the filtration chamber 3; The filtering device further includes a buffer stirring device 5, a membrane filter plate 6, and an impurity discharge pipe 7. The buffer stirring device 5 is arranged below the buffer chamber 2, the membrane filter plate 6 is arranged below the buffer stirring device 5, and the inlet of the impurity discharge pipe 7 is connected to the lower side of the filtration chamber 3; The buffer stirring device 5 further includes a driving motor 9, an outer shell 10, a worm 11, a worm gear 12, a bearing 13, a stirring rod 14, and an impeller 15. The driving motor 9 is arranged outside the outer shell 10. The input end of the worm 11 is connected to the output end of the driving motor 9, the output end of the worm 11 is engaged with the worm gear 12, the bearing 13 is arranged below the worm gear 12, the input end of the stirring rod 14 is connected to the worm gear 12, and the output end of the stirring rod 14 is connected to the impeller 15.

[0023] With the above solution, soy sauce enters the buffer chamber 2 from the feed port 1. After the kinetic energy buffering of the buffer stirring device 5, it enters the filtration chamber 3 along the inner wall of the box. The soy sauce flows smoothly onto the filter membrane filter plate 6 through the diversion structure, preventing the soy sauce from directly impacting the filter membrane, extending the service life of the filter membrane, reducing production costs. In the filtration chamber 3, macromolecular impurities are filtered out by the filter membrane filter plate 6, and the purified liquid falls into the next-level filtration device. The buffer stirring mechanism agitates the soy sauce in the buffer chamber 2. The driving motor 9 drives the worm 11 to rotate, and the worm 11 drives the worm wheel 12 to rotate on the bearing 13, thereby driving the impeller 15 on the lower stirring device to rotate, agitating the soy sauce in the filtration chamber 3, making the macromolecular impurities filtered out from the lower layer of the soy sauce rotate on the surface of the filter membrane, preventing the accumulation of impurities from reducing the filtration efficiency of the filter membrane, ensuring the fluidity of the soy sauce on the surface of the filter membrane, preventing the accumulation of macromolecular impurities on the surface of the filter membrane during the filtration process. The impurity discharge pipe 7 can discharge the impurities in the lower layer of the liquid in the filtration chamber 3, ensuring the filtration efficiency of the filter membrane.

[0024] Furthermore, buffer protrusions 8 are provided on the inner wall of the box;

[0025] Among them, after the soy sauce flows down from the buffer chamber 2, it passes through the buffer protrusions 8 and gently flows onto the filter membrane filter plate 6.

[0026] Further, the outer shell 10 is a conical structure;

[0027] Among them, the conical outer shell 10 structure enables the soy sauce in the buffer area to flow down smoothly.

[0028] Furthermore, the maximum outer diameter of the outer shell 10 is smaller than the inner diameter of the box;

[0029] Among them, the liquid in the buffer area can flow into the filtration chamber 3 along the gap between the outer shell 10 and the box and along the inner wall of the box.

[0030] Further, a diversion plate 16 is provided at the lower edge of the outer shell 10;

[0031] Among them, the diversion plate 16 can provide a more stable flow environment for the soy sauce flowing down along the inner wall, prevent the impact of the soy sauce on the filter membrane filter plate 6, extend the service life of the filter membrane, and reduce production costs.

[0032] Furthermore, a sewage discharge valve 17 is also provided on the impurity discharge pipe 7;

[0033] Among them, the sewage discharge valve 17 can control the discharge of impurities in the impurity discharge pipe 7, achieving the effect of cleaning impurities during the filtration process and ensuring the filtration efficiency of the filter membrane.

[0034] In summary, the device includes a box body and a filtering device. The buffer chamber 2 of the box body can pre-receive soy sauce from the previous process. After being buffered by the buffer stirring device 5, the soy sauce is discharged into the next process through the inner wall of the box body. The buffer protrusions 8 on the box body can further reduce the kinetic energy of the soy sauce, prevent the impact of the soy sauce on the filter membrane filter plate 6, extend the service life of the filter membrane, and reduce the production cost. The stirring mechanism can stir the soy sauce in the filtering chamber 3 to prevent impurities from continuously accumulating on the surface of the filter membrane filter plate 6 during the filtering process. The impurity discharge pipe 7 can discharge the accumulated impurities, ensuring the filtering efficiency of the filter membrane.

[0035] The working principle of the present utility model: Soy sauce enters the buffer chamber 2 from the feed inlet 1. After being buffered by the outer shell 10, the soy sauce flows downward along the gap between the outer shell 10 and the box body into the filtering chamber 3. The guide plate 16 below the outer shell 10 enables the soy sauce to flow smoothly downward. At the same time, through the further buffering of the buffer protrusions 8 on the downward-flowing soy sauce, the soy sauce can gently fall onto the filter membrane filter plate 6, preventing the impact of the soy sauce on the filter membrane filter plate 6, extending the service life of the filter membrane, and reducing the production cost.

[0036] After the soy sauce enters the buffer chamber 2 and is filtered through the filter membrane filter plate 6, impurities and purified liquid are produced. The impurities remain on the upper surface of the filter membrane filter plate 6, and the purified liquid enters the next process from the filter membrane filter plate 6. The device can be set for multi-stage filtration, and only by adding a buffer stirring device 5 and a filter membrane filter plate 6 after the filter membrane filter plate 6.

[0037] During the filtering process, the driving motor 9 in the buffer stirring mechanism drives the worm 11 to rotate. The worm 11 drives the worm gear 12 to rotate on the bearing 13, thereby driving the impeller 15 on the lower stirring device to rotate, stirring the soy sauce in the filtering chamber 3, and keeping the macromolecular impurities filtered out from the lower layer of the soy sauce rotating on the surface of the filter membrane, preventing the accumulation of impurities from reducing the filtering efficiency of the filter membrane. After long-term use, the sewage discharge valve 17 on the impurity discharge pipe 7 can be opened to discharge the accumulated impurities, preventing the blockage of the filter membrane by the accumulation of impurities, and ensuring the filtering efficiency of the filter membrane.

[0038] The purified liquid of the filtered soy sauce is discharged from the discharge port 4 to the next process, thus completing the filtration of the soy sauce.
