[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present utility model and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figure 1 shown, an embodiment of the present utility model provides a filtering device, which includes a filter cartridge 10 and a housing. The filter cartridge 10 has a receiving cavity 11 and a communication port 12 that communicate with each other. A plurality of filter holes 14 are provided on the inner wall of the filter cartridge 10, and all the plurality of filter holes 14 communicate with the receiving cavity 11. The filter holes 14 are used to filter out yeast in the raw material. The wall thickness of the filter cartridge 10 is set between 1.9 mm and 2 mm. The housing has a feed port, a discharge port, and a sewage discharge port. The filter cartridge 10 is disposed inside the housing. There is a filtering cavity between the filter cartridge 10 and the housing, and the filtering cavity communicates with the discharge port. The feed port extends into the receiving cavity 11 through the communication port 12. The sewage discharge port is disposed at the bottom of the housing and is correspondingly disposed with the communication port 12.

[0023] Applying the technical solution of the present application, the filter cartridge 10 is disposed inside the housing. The raw material enters the receiving cavity 11 through the feed port. Yeast enters the filtering cavity through the filter holes 14 and is discharged through the discharge port. Impurities are sequentially discharged through the communication port 12 and the sewage discharge port. Among them, in the present application, the wall thickness of the filter cartridge 10 is set between 1.9 mm and 2 mm. When the wall thickness of the filter cartridge 10 is less than 1.9 mm, the wall thickness of the filter cartridge 10 is relatively thin, and the filter cartridge 10 is extremely likely to be deformed or even damaged during use, thereby increasing the filtering cost of yeast. When the wall thickness of the filter cartridge 10 is greater than 2 mm, the wall thickness of the filter cartridge 10 is relatively thick, thereby increasing the difficulty of processing the filter holes 14. Therefore, setting the wall thickness of the filter cartridge 10 between 1.9 mm and 2 mm can not only avoid deformation and damage of the filter cartridge 10, avoid frequent maintenance or replacement of the filter cartridge 10, reduce the filtering cost of yeast, but also reduce the difficulty of processing the filter holes 14, thereby reducing the processing cost.

[0024] Specifically, in the present application, during the process of filtering yeast, impurities will adsorb on the filter cartridge 10, and the filter cartridge 10 needs to be cleaned with clean water. The sewage after cleaning will flow along the inner wall of the filter cartridge 10 to the sewage discharge port and be discharged from the sewage discharge port.

[0025] Further, the sewage discharge port has a blocked state and an open state. During the process of filtering yeast, the sewage discharge port is in the blocked state, and during the process of cleaning the filter cartridge, the sewage discharge port is in the open state.

[0026] Moreover, the sewage outlet is located at the bottom of the filter cartridge 10, so that the feed inlet and the sewage outlet will not interfere with each other, preventing sewage from entering the feed inlet.

[0027] Optionally, the wall thickness of the filter cartridge 10 can be set to 1.9 mm, 1.95 mm or 2 mm. In this application, the wall thickness of the filter cartridge 10 is set to 2 mm.

[0028] Among them, in the prior art, the thickness of the original filter cartridge 10 of the filtering device is 1 mm. During use, deformation and breakage usually occur, and the price of purchasing the original filter cartridge 10 is expensive. Through on-site research and mapping, combined with the operating conditions, the wall thickness of the filter cartridge 10 is set between 1.9 mm and 2 mm.

[0029] Specifically, the filter holes 14 have an arc-shaped structure. Among them, in the prior art, the filter holes 14 are set as triangles, and stress concentration is extremely likely to occur at the connection of the two sides of the filter holes 14, resulting in the filter holes 14 being extremely prone to breakage. Therefore, in this application, the filter holes 14 are designed as an arc-shaped structure, which can reduce stress concentration, prevent the filter holes 14 from breaking, and further improve the service life of the filter cartridge 10.

[0030] Furthermore, the filter holes 14 are of a circular structure. With this setting, it is convenient to process the filter holes 14, further reducing the processing difficulty of the filter cartridge 10 and reducing the processing cost.

[0031] Optionally, the filter holes 14 can be ellipses or perfect circles.

[0032] Among them, in this application, the filter holes 14 are perfect circles, and the diameter of the filter holes 14 is set between 0.4 mm and 0.5 mm.

[0033] When the diameter of the filter holes 14 is less than 0.4 mm, yeast is not easily discharged from the filter holes 14, which will cause some yeast to be discharged through the stirring port 13 together with impurities, thereby increasing the loss of yeast and the production cost of yeast; when the diameter of the filter holes 14 is greater than 0.5 mm, impurities are extremely likely to be discharged from the filter holes 14, resulting in a poor filtering effect of the filtering device and reducing the quality of yeast. Therefore, setting the diameter of the filter holes 14 between 0.4 mm and 0.5 mm can not only reduce the loss of yeast and the production cost of yeast, but also ensure the quality of yeast, thereby ensuring the user experience of consumers.

[0034] Optionally, the diameter of the filter holes 14 can be set to 0.4 mm, 0.45 mm or 0.5 mm. In this application, the diameter of the filter holes 14 is 0.5 mm.

[0035] Specifically, the distance between two adjacent filter holes 14 is set between 1.1 mm and 1.5 mm, that is, the center distance between two adjacent filter holes 14 is set between 1.1 mm and 1.5 mm.

[0036] When the distance between two adjacent filter holes 14 is less than 1.1 mm, the distance between two adjacent filter holes 14 is too small, which is extremely likely to cause damage to the filter cartridge 10 during the processing of the filter holes 14, and at the same time reduces the structural strength of the filter cartridge 10, and the filter cartridge 10 is extremely likely to be damaged during the working process; when the distance between two adjacent filter holes 14 is greater than 1.5 mm, the distance between two adjacent filter holes 14 is too large, which will reduce the filtration rate of yeast and thus reduce the production rate of yeast.

[0037] Therefore, setting the distance between two adjacent filter holes 14 between 1.1 mm and 1.5 mm can not only avoid damage to the filter cartridge 10, but also ensure the filtration rate and production rate of yeast.

[0038] Wherein, a communication port 12 is provided on one side of the filter cartridge 10, and a stirring port 13 is provided on the other side of the filter cartridge 10. The stirring port 13 is in communication with the accommodating cavity 11. That is, in this application, the stirring port 13 is located at the top of the filter cartridge 10, and the communication port 12 is located at the bottom of the filter cartridge 10. The filtering device further includes a rotary brush, which is rotatably arranged in the accommodating cavity and is arranged at the stirring port 13. The rotary brush can clean the inner wall of the filter cartridge 10, so as to remove impurities on the inner wall. Such a setting facilitates the removal of impurities on the inner wall.

[0039] Further, a flange 15 is provided at the stirring port 13 of the filter cartridge 10, and a fixing groove is provided on the inner wall of the outer shell. The flange 15 and the fixing groove are detachably connected by fasteners. Such a setting facilitates the connection between the filter cartridge 10 and the outer shell, with a simple structure and convenient operation.

[0040] In this application, the flange 15 and the fixing groove are connected by bolts. Such a setting can ensure the connection strength between the flange 15 and the fixing groove and prevent the filter cartridge 10 from falling off from the outer shell.

[0041] Wherein, a first sealing ring is provided between the fixing groove and the flange 15. Such a setting can seal between the fixing groove and the flange 15 to avoid leakage of yeast, thereby reducing the loss of yeast.

[0042] Specifically, an abutting protrusion 16 is provided on the outer wall of the communication port 12 of the filter cartridge 10, and the abutting protrusion 16 abuts against the inner wall of the housing. And the abutting protrusion 16 is arranged between the discharge port and the sewage discharge port. That is, in the present application, the discharge port is located above the sewage discharge port, and the abutting protrusion 16 is arranged between the discharge port and the sewage discharge port. A second sealing ring is provided between the abutting protrusion 16 and the housing. With such a setting, it can be ensured that the yeast is discharged from the sewage discharge port after entering the filtering chamber, further avoiding yeast leakage, and thus further reducing yeast loss.

[0043] Further, in the present application, an annular groove is provided on the side wall of the abutting protrusion 16, and the second sealing ring is arranged in the annular groove. With such a setting, it is convenient to assemble the second sealing ring, and at the same time, the second sealing ring can be prevented from falling off.

[0044] Specifically, one side of the housing away from the stirring port 13 has a guiding section, the diameter of the guiding section gradually decreases along the direction away from the stirring port 13, the end of the guiding section away from the stirring port 13 has a sewage discharge port, and a feed port is provided on the side wall of the guiding section. With such a setting, it is convenient for the sewage to flow to the sewage discharge port and avoid the sewage from being blocked at the sewage discharge port.

[0045] Wherein, a feed pipe is penetrated through the guiding section, the feed pipe is obliquely arranged, and the feed pipe has a feed port. With such a setting, it is convenient to input raw materials into the accommodating cavity 11.
