Description

Technical Field

[0001] This utility model relates to the field of pet food production technology, and in particular to a screening and drying device for pet food production. Background Technology

[0002] In pet food production, material screening is a crucial step in ensuring product quality. Existing screening equipment typically uses a screen structure, where materials are poured or vibrated onto the screen, and the size of the screen's openings determines the particle size and grading. Qualified particles pass through the screen and proceed to the next process, while unqualified particles are trapped on the screen, thus achieving material separation.

[0003] However, existing screening equipment has the following technical shortcomings in practical use:

[0004] Screen clogging problem: Large particles or impurities that fail to pass through the screen will accumulate on the surface of the screen. As the screening process continues, these deposits will gradually clog the screen, hindering the passage of subsequent materials, thereby reducing screening efficiency, and even causing the equipment to be shut down for cleaning, affecting the continuity of production.

[0005] Lack of drying function: In pet food production, the moisture content of the materials can affect screening efficiency and subsequent processing. Existing screening equipment typically only has screening functions and lacks integrated drying components, making it impossible to perform secondary drying of the materials before or after screening. If the material moisture content is too high, it can easily cause the screen to stick or become clogged, further exacerbating the decline in screening efficiency. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a screening and drying device for pet food production.

[0008] Preferably, the inner screening shell is provided with rotating shafts on both the front and rear sides, the rotating shafts are rotatably connected to the outer screening shell, and the second discharge port is provided on the right side wall of the shell.

[0009] The drive module includes a first gear fixedly mounted on the rotating shaft and a first rack meshing with the first gear.

[0010] The drive module further includes a movable frame that moves left and right relative to the screening housing. The first rack is fixedly mounted on the movable frame. The housing or the screening housing is rotatably provided with a first lead screw, which is threadedly connected to the movable frame.

[0011] The housing or the screening shell is fixedly equipped with a first motor, the motor shaft of the first motor is fixedly connected to a second gear, and the first lead screw is equipped with a third gear that meshes with the second gear.

[0012] Preferably, the drying module includes an air duct fixedly disposed on the screening shell, the air duct having an air outlet facing the interior of the screening shell, and the air duct being provided with a connecting pipe.

[0013] Preferably, a material bin is provided above the screening outer shell, and a feeding channel communicating with the screening inner shell is provided below the material bin. A feeding shaft is rotatably arranged in the feeding channel, and feeding plates are arranged in an array along the circumference of the feeding shaft.

[0014] Preferably, the drive assembly includes a second motor fixedly mounted on the material bin, a fourth gear fixedly connected to the motor shaft of the second motor, and a fifth gear fixedly mounted on the feeding shaft that meshes with the fourth gear.

[0015] Compared with existing technologies, this invention, under the action of the drive module, can drive the inner screening shell to rotate relative to the outer screening shell, so that the first connecting port and the second connecting port can be connected or misaligned. When connected, the screen is tilted towards the second discharge port, and the material on the upper surface of the screen can be discharged through the second connecting port, the first connecting port, and the second discharge port; thus achieving the cleaning of the material on the upper surface of the screen. When the first connecting port and the second connecting port are misaligned, it is in normal screening mode, and the material can pass through the screen and be discharged downwards through the first discharge port. This invention can quickly clean the material accumulated on the upper surface of the screen, meeting the needs of use.

[0016] Moreover, the drying module provided in this invention can dry the material entering the screening inner shell with hot air. Attached Figure Description

[0031] See Figures 1-6A screening and drying device for pet food production includes a housing 10, within which a screening outer shell 210 is disposed, and a screening inner shell 220 is rotatably disposed within the screening outer shell 210. A screen 230 is disposed within the screening inner shell 220. A first discharge port 110 is disposed at the bottom of the housing 10, and a second discharge port 120 is disposed on the side wall of the housing 10. Both the screening outer shell 210 and the screening inner shell 220 have openings on their upper and lower sides. The wall surface of the screening outer shell 210 near the second discharge port 120 is a first arc-shaped surface 211, and the wall surface of the screening inner shell 220 near the second discharge port 120 is a first arc-shaped surface 211. The wall surface of the second discharge port 120 is a second arc-shaped surface 221, which is in contact with the first arc-shaped surface 211. The first arc-shaped surface 211 is provided with a first connecting port 212 that communicates with the second discharge port 120, and the second arc-shaped surface 221 is provided with a second connecting port 222 that communicates with the first connecting port 212. The housing 10 is provided with a drive module 40 for driving the inner screening shell 220 to rotate relative to the outer screening shell 210. The housing 10 is provided with a drying module 50 for drying the grain material.

[0032] In screening mode, the material falls from top to bottom onto the screen 230. As the entire casing 10 is driven by the vibration motor, the entire casing 10 vibrates, allowing the material to pass through the screen 230 and be output to the outside through the first discharge port 110. Some material larger than the aperture of the screen 230 remains on the upper surface of the screen 230.

[0033] In cleaning mode, the drive module 40 drives the inner screening shell 220 to rotate relative to the outer screening shell 210, moving the inner screening shell 220 from a first position to a second position. When the inner screening shell 220 is in the second position, the first connecting port and the second connecting port are connected to each other, and the screen is tilted towards the second discharge port. Figure 4 As shown, the material on the upper surface of the screen can be discharged to the outside through the second connecting port, the first connecting port, and the second discharge port; thereby cleaning the material on the upper surface of the screen.

[0034] In this invention, the first arc-shaped surface 211 and the second arc-shaped surface 221 are arranged so that they fit together, thereby causing the first connecting port 212 and the second connecting port 222 to be misaligned. In this state, the first arc-shaped surface 211 can close the second connecting port 222 to prevent material from being output into the housing 10.

[0035] See Figures 3 to 6The inner screening shell 220 has rotating shafts 200 on its front and rear sides, which are rotatably connected to the outer screening shell 210. The second discharge port 120 is located on the right side wall of the housing 10. The drive module 40 includes a first gear 410 fixedly mounted on the rotating shaft 200 and a first rack 420 meshing with the first gear 410. The drive module 40 also includes a movable frame 430 that moves left and right relative to the outer screening shell 210. The first rack 420 is fixedly mounted on the movable frame 430. The housing 10 or the outer screening shell 210 is rotatably mounted with a first lead screw 440, which is threadedly connected to the movable frame 430. The housing 10 or the outer screening shell 210 is fixedly mounted with a first motor 450. The motor shaft of the first motor 450 is fixedly connected to a second gear 460. The first lead screw 440 is provided with a third gear 470 that meshes with the second gear 460.

[0036] The first lead screw 440 rotates in either the forward or reverse direction, driving the movable frame 430 to move left or right relative to the screening outer shell 210, thereby causing the first rack 420 to move right or left. When the first rack 420 moves, it drives the first gear 410 to rotate, thereby causing the screening inner shell 220 to rotate. The purpose of using the first lead screw 440 for driving in this invention is that the first lead screw 440 has a self-locking function, allowing the movable frame 430 to move freely.

[0037] Regarding the rotation of the first lead screw 440, it is driven by the first motor 450, and its rotation is achieved through the cooperation of the second and third gears. The forward or reverse rotation of the first lead screw 440 is driven by the first motor 450.

[0038] See Figure 4 and Figure 5 The drying module 50 includes an air duct 510 fixedly installed on the screening outer shell 210. The air duct 510 has an air outlet 520 facing the interior of the screening inner shell 220, and a connecting pipe 500 is provided on the air duct 510. The connecting pipe 500 is used to connect to an external hot air blower. The hot air blown from the air outlet 520 through the air duct 510 into the interior of the screening inner shell 220 carries away residual moisture in the material through heat.

[0039] See Figure 4 and Figure 5A material bin 30 is disposed above the screening outer shell 210, and a feeding channel 310 communicating with the screening inner shell 220 is disposed below the material bin 30. A feeding shaft 320 is rotatably disposed within the feeding channel 310, and feeding plates 330 are arranged in a circular array along the circumference of the feeding shaft 320. The material bin 30 is provided with a drive assembly 300 for driving the feeding shaft 320 to rotate. In this embodiment, the material bin 30 serves a storage function. As the drive assembly 300 operates, it can drive the feeding shaft 320 to rotate, thereby driving the feeding plates 330 to push the material from top to bottom into the screening inner shell 220.

[0040] See Figure 4 The drive assembly 300 includes a second motor 350 fixedly installed in the material bin 30. The motor shaft of the second motor 350 is fixedly connected to a fourth gear 360. The feeding shaft 320 is fixedly installed with a fifth gear 340 that meshes with the fourth gear 360.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
