Description

Technical Field

[0001] This application relates to the field of impurity removal technology, and in particular to a device for removing fine impurities from fishmeal raw materials. Background Technology

[0002] Fishmeal is an important feed ingredient, and its quality directly affects the aquaculture effect. During the production process, the raw materials are often mixed with fine impurities such as sand, hair, and magnetic metals. As the feed industry raises its requirements for fishmeal quality, efficient removal of impurities has become a key link in ensuring the quality of fishmeal. Various special removal equipment have emerged to meet the needs of industrial production.

[0003] However, existing equipment for removing fine impurities from fishmeal raw materials has the following drawbacks: For example, fishmeal raw materials are usually directly fed onto a sieve plate and impurities are sieved out by gravity. However, this method makes it difficult to distribute the fishmeal raw materials evenly across the entire sieve surface. It is easy for some parts of the material to be too thick while other parts are thin. Fine impurities in the thicker material layer are more difficult to pass through the sieve holes, resulting in uneven sieving and affecting the overall quality of the fishmeal. Utility Model Content

[0004] The purpose of this application is to enable fishmeal raw materials to be distributed more evenly on the screen surface, ensuring the consistency of screening quality and improving screening efficiency.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: The device includes a housing; a mounting plate is fixedly connected to the side wall of the housing; a motor is fixedly connected to the upper surface of the mounting plate; a rotating shaft is fixedly connected to the output end of the motor; a rotating frame is fixedly connected to the upper surface of the rotating shaft; a screening assembly is provided inside the housing; the screening assembly includes a movable frame; an installation groove is formed on the inner wall of the movable frame; a screen plate is disposed inside the installation groove; a first connecting plate is fixedly connected to the side wall of the movable frame; a second connecting plate is fixedly connected to the side wall of the first connecting plate; a roller is fixedly connected to the lower surface of the second connecting plate, the roller being located inside the rotating frame; a third connecting plate is fixedly connected to the upper surface of the first connecting plate; three springs are fixedly connected to the side wall of the third connecting plate; the end of each spring furthest from the third connecting plate is fixedly connected to the side wall of the housing.

[0006] As a preferred embodiment, a fixing plate is fixedly connected to the upper surface of the sieve plate, a first threaded groove is formed on the side wall of the fixing plate, a second threaded groove is formed on the side wall of the movable frame, a bolt is threadedly connected to the inner surface of the first threaded groove, a bolt is threadedly connected to the inner surface of the second threaded groove, a nut is threadedly connected to the outer surface of the bolt, and the nut is located on the left side of the movable frame.

[0007] As another preferred embodiment, the inner wall of the device housing is fixedly connected with a support plate, and there are two support plates, with the lower surface of the movable frame fitting against the upper surface of the support plate.

[0008] In a further preferred embodiment, a feeding trough is provided on the upper surface of the equipment housing, and a feeding hopper is fixedly connected to the upper surface of the equipment housing, with the feeding trough and the feeding hopper being connected in communication.

[0009] As a preferred embodiment, a first gathering member is fixedly connected to the inner wall of the device housing, and the first gathering member is located above the screening assembly.

[0010] As another preferred embodiment, a second gathering member is fixedly connected to the inner wall of the device housing, and the second gathering member is located below the screening assembly.

[0012] As a preferred embodiment, the lower surface of the device housing is fixedly connected with four legs.

[0013] Compared with the prior art, the beneficial effects of this application are as follows:

[0014] Compared with existing technologies, this fishmeal raw material fine impurity removal device comprises a motor, a rotating shaft, a rotating frame, a spring, a third connecting plate, rollers, a second connecting plate, a first connecting plate, a moving frame, and a sieve plate. When fishmeal needs to be sieved, the motor drives the rotating shaft to rotate, which in turn drives the rotating frame to rotate around the shaft. Since the rotating shaft is not connected to the center of the rotating frame, and the spring always provides a leftward elastic force to the third connecting plate, the rotation of the rotating frame around the shaft causes the rollers to roll along the inner surface of the rotating frame. This, in turn, causes the second connecting plate to reciprocate left and right, thus enabling... The first connecting plate is driven to reciprocate left and right, which in turn drives the moving frame and screen plate to reciprocate left and right. This allows the screen plate to better screen the fishmeal. Compared with existing impurity removal equipment, which is difficult to distribute the fishmeal raw material evenly across the entire screen surface and is prone to localized thicker material layers while other areas are thinner, the fine impurities in the thicker material layers are more difficult to pass through the screen holes, resulting in uneven screening and affecting the overall quality of the fishmeal. This fishmeal raw material fine impurity removal equipment can make the fishmeal raw material more evenly distributed on the screen surface, ensuring the consistency of screening quality and improving screening efficiency.

[0029] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0030] like Figure 1-10The fishmeal raw material fine impurity removal device shown includes a housing 1. A mounting plate 2 is fixedly connected to the side wall of the housing 1. A motor 3 is fixedly connected to the upper surface of the mounting plate 2. A rotating shaft 4 is fixedly connected to the output end of the motor 3. A rotating frame 5 is fixedly connected to the upper surface of the rotating shaft 4. The rotating shaft 4 is not located at the center of the rotating frame 5. A screening assembly 6 is provided inside the housing 1. The screening assembly 6 includes a moving frame 601. An installation groove 602 is formed on the inner wall of the moving frame 601. A screen plate 603 is provided inside the installation groove 602. A first connecting plate 7 is fixedly connected to the side wall of the moving frame 601. A second connecting plate 8 is fixedly connected to the side wall of the first connecting plate 7. A roller 9 is fixedly connected to the lower surface of the second connecting plate 8. The roller 9 is located inside the rotating frame 5. A third connecting plate 10 is fixedly connected to the upper surface of the first connecting plate 7. A spring 11 is fixedly connected to the side wall of the third connecting plate 10. The spring 11 is always under pressure. In the contracted state, the spring 11 continuously provides a leftward elastic force to the third connecting plate 10, which in turn provides a continuous leftward elastic force to the first connecting plate 7, the second connecting plate 8, and the roller 9. There are three springs 11. When fish meal needs to be sieved, the motor 3 drives the rotating shaft 4 to rotate, which in turn drives the rotating frame 5 to rotate around the rotating shaft 4. Since the rotating shaft 4 is not connected to the center of the rotating frame 5, and the spring 11 always provides a leftward elastic force to the third connecting plate 10, the rotating frame 5 will drive the roller 9 to roll along the inner surface of the rotating frame 5 when it rotates around the rotating shaft 4. Therefore, it can drive the second connecting plate 8 to move left and right, and thus drive the first connecting plate 7 to move left and right. Therefore, it can drive the moving frame 601 and the sieve plate 603 to move left and right, so that the sieve plate 603 can better sieve the fish meal. The end of the spring 11 away from the third connecting plate 10 is fixedly connected to the side wall of the equipment housing 1.

[0031] A fixing plate 604 is fixedly connected to the upper surface of the screen plate 603. A first threaded groove 605 is provided on the side wall of the fixing plate 604, and a second threaded groove 606 is provided on the side wall of the moving frame 601. A bolt 607 is threadedly connected to the inner surface of the first threaded groove 605, and a bolt 607 is threadedly connected to the inner surface of the second threaded groove 606. A nut 608 is threadedly connected to the outer surface of the bolt 607. The nut 608 is located on the left side of the moving frame 601. By turning the nut 608 to remove it, and then turning the bolt 607 to remove it, the moving frame 601 and the fixing plate 604 are no longer fixed, and the moving frame 601 and the screen plate 603 are no longer fixed, so the screen plate 603 can be removed for cleaning. A support plate 12 is fixedly connected to the inner wall of the equipment housing 1. The support plate 12 can support the moving frame 601. There are two support plates 12. The lower surface of the moving frame 601 is in contact with the upper surface of the support plate 12.

[0032] A feeding trough 13 is provided on the upper surface of the equipment housing 1, and a feeding hopper 14 is fixedly connected to the upper surface of the equipment housing 1. The feeding trough 13 and the feeding hopper 14 are connected. Fish meal raw material is poured in through the feeding hopper 14 and falls through the feeding trough 13 onto the first gathering member 15. The first gathering member 15 gathers the fish meal and it falls into the moving frame 601. Impurities in the fish meal are screened out through the sieve plate 603. The fish meal continues to fall through the sieve plate 603 onto the second gathering member 16, where it is further gathered. Finally, it falls through the discharge trough 17 and the discharge pipe 18. A discharge pipe 18 is provided below the discharge pipe 18. There are corresponding collection components to collect fishmeal. The inner wall of the equipment housing 1 is fixedly connected to a first gathering member 15, which is located above the screening component 6. The inner wall of the equipment housing 1 is fixedly connected to a second gathering member 16, which is located below the screening component 6. A discharge trough 17 is opened on the lower surface of the equipment housing 1. A discharge pipe 18 is fixedly connected to the lower surface of the equipment housing 1 and is connected to the discharge trough 17. Four support legs 19 are fixedly connected to the lower surface of the equipment housing 1 to support the equipment housing 1.

[0033] Working principle: When fishmeal needs to be sieved, motor 3 drives shaft 4 to rotate, which in turn drives rotating frame 5 to rotate around shaft 4. Since shaft 4 is not connected to the center of rotating frame 5, and spring 11 always provides a leftward elastic force to third connecting plate 10, rotating frame 5 rotates around shaft 4, causing roller 9 to roll along the inner surface of rotating frame 5. This drives second connecting plate 8 to reciprocate left and right, which in turn drives first connecting plate 7 to reciprocate left and right. Consequently, moving frame 601 and sieve plate 603 move left and right. The reciprocating motion allows the sieve plate 603 to better sieve the fishmeal. The fishmeal raw material is poured in through the feed hopper 14 and falls through the feed chute 13 onto the first gathering member 15. The first gathering member 15 then gathers the fishmeal and it falls into the moving frame 601. The sieve plate 603 sieves out the impurities in the fishmeal. The fishmeal continues to fall through the sieve plate 603 onto the second gathering member 16, where it is further gathered. Finally, it falls through the discharge chute 17 and the discharge pipe 18. A corresponding collection component is provided below the discharge pipe 18 to collect the fishmeal.
