[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] Embodiment 1

[0043] Referring to Figure 4, a raw milk filtering device for yogurt processing includes a main body component 1, which includes: a filter box 11, the top of which is hinged with a cover 12; a feed pipe 13, which is connected to the left side wall of the filter box 11; a feed hopper 14, which is set through the top of the feed pipe 13; a discharge pipe 15, which is set through the right side wall of the filter box 11; a filter component 2 is set on the filter box 11, and the filter component 2 includes: a bottom plate 21, which is movably set on the right side wall of the filter box 11, and the left end of the bottom plate 21 penetrates and extends into the inside of the filter box 11; a motor 22, which is set on the top of the bottom plate 21 A rotating shaft 23 is fixedly connected to the output shaft of the motor 22; a fixed block 24 is movably connected to the left end of the rotating shaft 23, and the rotating shaft 23 is fixedly connected to the left side wall of the fixed block 24; a filter tank 25 is fixedly connected to the left side of the rotating shaft 23 at the left end of the fixed block 24, and the output end of the feed pipe 13 extends to the inside of the filter tank 25; a sleeve 26 is rotatably connected to the left side wall of the fixed block 24, and the sleeve 26 penetrates and extends to the inside of the filter tank 25; a scraper 261 is fixedly connected to the outside of the sleeve 26; a connecting mechanism 27 is arranged on the bottom plate 21 and the fixed block 24. The connecting mechanism 27 includes: an electric push rod 271, which is arranged on the right side wall of the filter box 11, and the output end of the electric push rod 271 is fixedly connected to the bottom plate 21; a pull rod 272, which is arranged on the outer side wall of the fixing block 24, and one end of the pull rod 272 penetrates and extends into the inside of the fixing block 24; a limit block 273, which is arranged at one end of the pull rod 272 located inside the fixing block 24; a spring 274, which is sleeved on the outside of the pull rod 272; and a limit hole 275, which is opened at the left end of the rotating shaft 23. The limit blocks 273 and the limit holes 275 are arranged in multiple groups symmetrically around the circumference.

[0044] When in use, the staff pours the raw milk into the feed hopper 14, and the raw milk enters the filter tank 25 through the feed pipe 13, and the motor 22 is started. The motor 22 drives the rotating shaft 23 and the fixed block 24 to rotate, and the filter tank 25 connected to the left end of the fixed block 24 by a rotating shaft 23 rotates, and the raw milk inside the filter tank 25 moves toward the inner wall of the filter tank 25 by the centrifugal force generated during the rotation. When the filter tank 25 rotates, the filtered raw milk is sprinkled into the filter box 11 and discharged from the filter box 11 through the discharge pipe 15. The filtered impurities remain in the filter tank 25, and the rotary filtration improves the filtration efficiency. When the filter tank 25 rotates, the sleeve 26 connected to the left wall of the fixed block 24 rotates and drives the scraper 261 not to rotate with the filter tank 25. When the filter tank 25 rotates, the scraper 261 evenly contacts the inner wall of the filter tank 25 to prevent impurities from accumulating and adhering to the inner wall, thereby avoiding affecting the subsequent filtration of the raw milk. After the raw milk is filtered, the cover body 12 can be opened, and the filter tank 25 can be removed for cleaning through the connecting mechanism 27: the staff starts the electric push rod 271, and the electric push rod 271 pushes the bottom plate 21 and the motor 22 to the right. At this time, the left end of the filter tank 25 is separated from the feed pipe 13, and the pull rod 272 is pulled outward. The pull rod 272 drives the limit block 273 to disengage from the limit hole 275 on the rotating shaft 23. At this time, the rotating shaft 23 is not restricted by the fixed block 24, and the fixed block 24 and the filter tank 25 can be removed together for cleaning to avoid bacterial growth. When installing the filter tank 25, pull the pull rod 272 outward, the pull rod 272 drives the limit block 273 to move upward and compress the spring 274, move the fixed block 24, and after the left end of the rotating shaft 23 is inserted into the right cavity of the fixed block 24, release the pull rod 272, the spring 274 elastic force will bounce the limit block 273 into the limit hole 275, complete the connection between the fixed block 24 and the rotating shaft 23, and then start the electric push rod 271 to move the bottom plate 21 and the motor 22 to the left, and after the right end of the feed pipe 13 is inserted into the filter tank 25, close the electric push rod 271, close the cover 12, and filter the raw milk again. The limit block 273 and the limit hole 275 are symmetrically arranged in multiple groups to improve the stability of the connection between the rotating shaft 23 and the fixed block 24.

[0045] Embodiment 2

[0046] On the basis of the first embodiment, an auxiliary function is added.

[0047] See also Figure 1-4 The inner bottom surface of the filter box 11 has an inclined surface, which is inclined in the direction of the discharge pipe 15. A sealing ring 251 is fixedly connected to the feed port at the left end of the filter tank 25, and the sealing ring 251 is movably connected to the outside of the feed pipe 13. The bottom end of the limit block 273 has an inclined surface.

[0048] The inclined surface of the bottom surface of the filter box 11 increases the speed at which the filtered raw milk flows to the discharge pipe 15, and prevents the raw milk from accumulating inside, which makes it inconvenient for the staff to clean it. The sealing ring 251 seals the interface between the filter tank 25 and the feed pipe 13 to prevent the raw milk from flowing out of the interface gap when the filter tank 25 rotates for filtering, thereby affecting the quality of the raw milk after filtration. The side of the bottom end of the limit block 273 close to the rotating shaft 23 is an inclined surface, so when installing the filter tank 25, it is only necessary to move the fixed block 24 to the right. During the process of the rotating shaft 23 extending into the cavity on the right side of the fixed block 24, the left end of the rotating shaft 23 contacts the inclined surface at the bottom end of the limit block 273 and pushes multiple groups of limit blocks 273 outward at the same time. The rotating shaft 23 continues to move toward the inside of the fixed block 24 until the limit hole 275 moves to the bottom of the limit block 273. The compressed spring 274 uses the elastic force to push the limit block 273 into the limit hole 275. The connection between the fixed block 24 and the rotating shaft 23 can be completed without pulling the pull rod 272, thereby improving the convenience of operation.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
