Description

Technical Field

[0001] The present invention relates to the technical field of filtering devices, in particular to a multi-stage slurry filtering device for yuba production. Background Art

[0002] Yuba is a common soy product food, mainly containing plant protein, and its unique flavor is deeply loved by everyone. Yuba is made from soybeans through steps such as bean selection, bean soaking, soy milk grinding, soy milk boiling, slurry filtering, yuba extraction, drying, and cutting.

[0003] Among them, slurry filtering is an important part of the yuba production process. The quality of the original slurry obtained by slurry filtering directly affects the extraction of yuba. If the quality of the slurry obtained after slurry filtering is poor, the quality and flavor of the extracted yuba will be directly affected. However, the existing slurry filtering devices generally only perform one-time slurry filtering during use, and then the obtained slurry is used for auxiliary production, and the quality of the produced yuba still needs to be improved. Moreover, when the existing slurry filtering devices are in use, impurities in the slurry are likely to block the filter screen, thereby affecting the efficiency of slurry filtering. To solve the above problems, this application specifically proposes a multi-stage slurry filtering device for yuba production. Summary of the Invention

[0004] In view of the above situation, to overcome the deficiencies of the prior art, the present invention provides a multi-stage slurry filtering device for yuba production. The technical solution for solving the problem is as follows: It includes an outer cylinder. It is characterized in that a support frame is coaxially and fixedly connected to the bottom of the outer cylinder. The upper end of the support frame is coaxially and rotatably connected to a rotating shaft.

The arc plate is integrally and uniformly provided with a number of bristles for cooperating with the second-stage slurry filtering component. The vertical reciprocating motion component drives a small gear. The support frame is coaxially and fixedly connected with a support member. The support member is rotatably connected with a ring. The outer edge of the ring is fixedly connected with a plurality of connecting rods evenly distributed around its axis. The plurality of connecting rods are jointly fixedly connected with a large gear ring meshing with the small gear.

[0019] The following further elaborates on the detailed implementation manners of the present invention in conjunction with the attached Figure 1-7 drawings.

[0020] In Embodiment 1, the technical solution adopted is that when the present application is in use, the mesh numbers of the primary filter screen 19, the secondary filter screen 24, and the tertiary filter screen 8 decrease successively, thereby ensuring the filtration quality of the auxiliary slurry. Further, the primary filter slurry assembly 6 is detachably connected, facilitating its maintenance and cleaning to ensure the filter slurry efficiency; the secondary filter screen 24 can ensure the use effect and the filter slurry efficiency under the cleaning action of the brush; the tertiary filter screen 8 can ensure that the filter screen is not blocked under the action of the scraper 17, thereby ensuring the filter slurry efficiency.

[0021] Example 2. On the basis of Example 1, specifically, when the present application is in use, the slurry that needs to be filtered is poured into the primary filter slurry assembly 6. The mesh number of the primary filter screen 19 is relatively large, which can filter out large-particle impurities in the slurry. After the slurry passes through the primary filter screen 19 and enters the centrifuge cylinder 5, the centrifuge motor 4 below the support frame 2 is started. The centrifuge motor 4 will drive the rotating shaft 3 and the centrifuge cylinder 5 to rotate at a high speed. As a result, the slurry in the centrifuge cylinder 5 passes through the through slots 23 and the secondary filter screen 24 and enters the outer cylinder 1. Under the action of the secondary filter screen 24, impurities with smaller particle sizes can be further filtered out to ensure the quality of the slurry entering the outer cylinder 1. The slurry entering the outer cylinder 1 will be filtered for the third time through the tertiary filter screen 8. The mesh number of the tertiary filter screen 8 is smaller, so that impurities with even smaller particle sizes can be filtered out to ensure the quality of the slurry passing through the tertiary filter screen 8. After passing through the tertiary filter screen 8, the slurry will fall into the collection tank 34 fixedly connected to the support leg 33. Opening the discharge valve 36 can discharge the slurry in the collection tank 34 from the discharge pipe 35.

[0022] Example 3. On the basis of Example 2, when filtering through the present application, since the mesh number of the primary filter screen 19 is relatively large, the probability of its blockage is relatively low, and it can be disassembled and cleaned regularly. The mounting ring 18 of the primary filter slurry assembly 6 is connected to the lower flange 20 on the centrifuge cylinder 5 through the upper flange 21 and bolts 22, which is convenient for disassembly. Further, in order to prevent blockage of the secondary filter screen 24 and the tertiary filter screen 8, the drive motor 29 on the straight plate 25 should be started during the filter slurry operation to make the vertical reciprocating motion assembly 9 work. As a result, the bristles 11 on the arc plate 10 can clean the secondary filter screen 24, and at the same time, the scraper 17 can clean the tertiary filter screen 8.

[0023] Specifically, when the drive motor 29 starts, it will drive the reciprocating lead screw 27 to rotate. The rotation of the reciprocating lead screw 27 will drive the reciprocating rod 28 to move vertically back and forth along the vertical rod 26. Consequently, the arc-shaped plate 10 fixedly connected to the reciprocating rod 28 and the bristles 11 on the arc-shaped plate 10 will also move vertically back and forth accordingly. During the reciprocating movement of the bristles 11 along with the arc-shaped plate 10, since the secondary filter screen 24 rotates synchronously with the centrifugal cylinder 5, the bristles 11 on the arc-shaped plate 10 can comprehensively clean the rotating secondary filter screen 24 during the reciprocating movement. Because the brush abuts against the secondary filter screen 24, the bristles 11 can penetrate into the mesh holes of the secondary filter screen 24 during the cleaning process to avoid blockage (in the drawings of this application, the diameter of the bristles 11 is exaggeratedly drawn, and the actual diameter of the bristles 11 can effectively clean the secondary filter screen 24); during the rotation of the reciprocating lead screw 27, the small gear 12 at the lower end of the reciprocating lead screw 27 can also drive the large gear ring 16 meshing with it, causing the large gear ring 16, together with the connecting rod 15 and the circular ring 14, to rotate around the mounting sleeve 31 on the support member 13. By meshing the small gear 12 with the large gear, the rotation speed of the large gear ring 16 and related components can be effectively controlled to prevent them from rotating too fast. During the rotation of the large gear ring 16 together with the connecting rod 15, the scraper 17 at the lower end of the connecting rod 15 will also rotate accordingly to clean the tertiary filter screen 8, ensuring the slurry filtering efficiency of the tertiary filter screen 8. The slurry in the outer cylinder 1 can also be stirred by components such as the scraper 17 to further improve its efficiency of passing through the tertiary filter screen 8.

[0024] Embodiment 4: On the basis of Embodiment 3, a protective cover 37 is fixedly connected to the support frame 2, and the two cooperate to provide a certain degree of protection for the centrifugal motor 4, facilitating the protection of the centrifugal motor 4. A slurry discharge port 32 is provided on the support sleeve 30 of the support member 13 to facilitate the passage of slurry and prevent slurry from accumulating in the support sleeve 30.
