Technical Field
[0001] This utility model relates to the technical field of feed raw material screening equipment, and in particular to a feed raw material screening and filtration device. Background Technology
[0002] As a core link in modern animal husbandry, feed processing directly affects the safety, nutrition, and animal health of feed products due to the quality of its raw materials. During the harvesting, transportation, and storage of feed raw materials such as fishmeal, impurities such as stones, metal scraps, plastics, straw, and moldy particles are often mixed in. Feed screening machines are often used for filtration when screening feed raw materials. The screening machine consists of a screen, a vibrating motor, an electromechanical box, a spring seat, and a discharge hopper.
[0003] Traditional screens have straight, flat mesh openings. During feeding, the feed is tilted from top to bottom, causing fishmeal to tend to accumulate in a cone shape on the screen surface, making it difficult to disperse. Simultaneously, impurities such as stones, metal fragments, and plastic in the fishmeal can easily become stuck on the screen surface, resulting in low mesh utilization. These impurities are difficult to remove effectively. Failure to remove these impurities not only reduces feed quality and damages the animal's digestive system but may also damage processing equipment, increasing maintenance costs. Therefore, a feed ingredient screening and filtration device is needed to solve these problems. Utility Model Content
[0004] The purpose of this invention is to solve the problems mentioned in the background section.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A feed ingredient screening and filtration device includes a vibrating screen, which comprises a vibrating motor, a spring assembly, a guide plate, and a discharge port. A housing base is connected below the spring assembly of the vibrating screen. The guide plate is connected to the top of the spring assembly, and a discharge port is provided on the side of the guide plate. A vibrating motor is installed at the bottom of the guide plate. A filter element is movably installed on one side of the top of the guide plate. The filter element includes a frame movably connected to the guide plate. A fixing ring is connected to the inner wall of the frame by screws, and a screen plate is connected to the top of the fixing ring. A discharge pipe is connected to the right side of the frame.
[0007] Preferably, the center of the sieve disc has an arc-shaped protrusion, and the lower end surface of the sieve disc gradually decreases towards the discharge pipe. The lower end surface of the sieve disc can guide the fishmeal feed, so that the fishmeal feed can be screened while moving.
[0008] Preferably, the inner wall of the screen frame is provided with a plurality of protruding ends, and the bottom end of the protruding end abuts against and fits against the top edge of the screen plate. When the screen plate is guided and installed, the protruding ends on the inner side of the screen frame can be used to install and position the screen plate, thereby ensuring the convenience of screen plate installation.
[0009] Preferably, a rubber curtain is connected to the bottom end of the fixing ring, and the rubber curtain is attached to the inner wall of the guide plate of the vibrating screen. By attaching the rubber curtain to the inner wall of the guide plate of the vibrating screen, the probability of fine fishmeal feed overflowing from the gap between the guide plate and the plate frame is effectively reduced.
[0010] Preferably, the inner wall of the fixed ring is connected to an annular guide plate, and the annular guide plate is inclined from the outside to the middle position. The fish meal feed that can fall through the annular guide plate is guided so that the fish meal feed can fall into the center of the guide plate of the vibrating screen.
[0011] Preferably, an insert plate is installed at the top of the discharge pipe via a slot, and an electric push rod is connected to the right side of the top of the insert plate. The electric push rod is installed on the top surface of the discharge pipe, and the movement of the insert plate is controlled by the extension and retraction of the piston rod end of the electric push rod, thereby controlling and adjusting the opening and closing state inside the discharge pipe.
[0012] Preferably, the side of the disc frame is connected to the side of the guide plate of the vibrating screener via a fixing member. The fixing member includes a threaded shaft movably installed on both sides of the guide plate of the vibrating screener. The threaded shaft is placed on the outside of the clamping plate through a groove. A screw cap is threadedly fitted onto the top of the threaded shaft. The clamping plate is connected and fixed to the outside of the disc frame. After the screw cap is threaded onto the surface of the threaded shaft, it abuts against the surface of the clamping plate, which can ensure the stable connection between the disc frame and the guide plate of the vibrating screener.
[0013] This utility model has at least the following beneficial effects:
[0014] 1. By setting up a screen disc, the device can guide and prevent the accumulation of feed ingredients. The screen disc is raised in an arc shape at the center, and the screen disc as a whole is higher in the middle and lower on the sides. The lower side of the screen disc gradually decreases towards the discharge pipe. The raised arc surface at the top of the screen disc can disperse the feed ingredients to the side. The screen disc vibrates, which can reduce the probability of fishmeal feed accumulating in a cone shape on the screen surface and effectively improve the utilization rate of the screen mesh.
[0015] 2. By setting a fixing component, the screen plate can be easily replaced and cleaned. After loosening by rotating the cap, the threaded shaft can be rotated to lift and open the screen frame, making it convenient for staff to push and clean the impurities in the screen holes from below. The fixing ring is fixed to the inner wall of the screen frame with bolts, making the screen plate and the screen frame modular, which improves the convenience of screen plate replacement to a certain extent.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0023] Reference Figure 1-4 A feed ingredient screening and filtration device includes a vibrating screen 2, which consists of a vibrating motor, a spring assembly, a guide plate, and a discharge port. A housing base 1 is connected to the bottom of the spring assembly of the vibrating screen 2. The top of the spring assembly of the vibrating screen 2 is connected to the guide plate, and the discharge port is provided on the side of the guide plate. A vibrating motor is installed at the bottom of the guide plate of the vibrating screen 2. A filter element 3 is movably installed on one side of the top of the guide plate of the vibrating screen 2. The filter element 3 includes a disc frame 31 movably connected to the guide plate. A fixing ring 33 is connected to the inner wall of the disc frame 31 by screws, and a screen disc 34 is connected to the top of the fixing ring 33. A discharge pipe 32 is connected to the right side of the disc frame 31.
[0024] The center of the screen plate 34 is arc-shaped and protrudes, while the lower side of the screen plate 34 gradually decreases towards the discharge pipe 32.
[0025] The inner wall of the screen frame 31 is provided with several protruding ends, and the bottom end of the protruding end is in contact with and fits against the top edge of the screen 34.
[0026] A rubber curtain 36 is connected to the bottom end of the fixed ring 33, and the rubber curtain 36 is attached to the inner wall of the guide plate of the vibrating screen 2.
[0027] The inner wall of the fixing ring 33 is connected to the annular guide disk 35, and the annular guide disk 35 is inclined from the outside to the middle.
[0028] A plate 37 is inserted into the top of the discharge pipe 32 via a slot, and an electric push rod 38 is connected to the right side of the top of the plate 37. The electric push rod 38 is installed on the top surface of the discharge pipe 32.
[0029] The side of the disc frame 31 is connected to the side of the guide plate of the vibrating screen 2 via a fastener 4. The fastener 4 includes a threaded shaft 41 that is movably installed on both sides of the guide plate of the vibrating screen 2. The threaded shaft 41 is placed on the outside of the clamping plate 42 through a groove. The top of the threaded shaft 41 is threaded with a screw cap 43. The clamping plate 42 is connected and fixed to the outside of the disc frame 31.
[0030] The arc-shaped protrusions of the sieve disc 34 guide the fishmeal feed to disperse, and the lower end face of the sieve disc 34 guides the fishmeal feed, allowing it to be screened while moving. Fixed impurities in the fishmeal feed can fall and be collected from the discharge pipe 32. When the sieve disc 34 is being installed, the protruding end on the inner side of the disc frame 31 can position the sieve disc 34, thus ensuring the ease of installation and allowing the threaded hole on the inner side of the disc frame 31 to quickly adapt to the mounting hole on the inner side of the fixing ring 33.
[0031] When the tray frame 31 is connected to the guide plate of the vibrating screen 2, the rubber curtain 36 can be inserted into the guide plate of the vibrating screen 2, so that the rubber curtain 36 fits against the inner wall of the guide plate of the vibrating screen 2, effectively reducing the chance of fine fishmeal feed overflowing from the gap between the guide plate and the tray frame 31. The fishmeal feed that can fall through the annular guide plate 35 is guided so that the fishmeal feed can fall into the center of the guide plate of the vibrating screen 2, which facilitates the centralized collection of fishmeal feed.
[0032] After the fishmeal feed is screened, the piston rod end of the electric push rod 38 can be extended and retracted to control the movement of the insert plate 37 and control the opening and closing state of the discharge pipe 32. When the disc frame 31 is attached to the top of the guide plate of the vibrating screener 2, it can be rotated and placed upright into the side groove of the clamping plate 42 by the threaded shaft 41. After the screw cap 43 is threaded onto the surface of the threaded shaft 41, it abuts against the surface of the clamping plate 42, which can ensure the stable docking of the disc frame 31 and the guide plate of the vibrating screener 2.
[0033] Working principle: According to the appendix Figure 1 With appendix Figure 3As shown, during operation, the fishmeal feed is poured onto the surface of the screen 34. The vibrating screen 2 is then activated. Under the action of the vibrating motor, the upper frame 31 vibrates at a high frequency. The screen 34 inside the frame 31 vibrates at a high frequency, causing the fishmeal feed to spread outwards under the guidance of the arc-shaped protrusion at the center of the screen 34. Since the sides of the screen 34 gradually decrease towards the discharge pipe 32, impurities generated during fishmeal filtration can roll along with the vibrations to the opening of the discharge pipe 32. At this time, the electric push rod 38 can be energized and started, so that the piston rod end of the electric push rod 38 pushes the insert plate 37, controlling the impurities to scatter and flow out from the discharge pipe 32, which is convenient for the independent collection of impurities. The filtered fish meal feed falls to the guide plate end of the vibrating screen 2. After the vibration of the guide plate end, the fish meal feed is moved to the discharge port position, which is convenient for centralized discharge operation. In its design, the vibrating screen 2 consists of a vibrating motor, a spring group, a guide plate and a discharge port. The guide plate and the screen plate 34 have the same undulating shape.
[0034] Secondly, according to the appendix Figure 2 With appendix Figure 3 As shown, when the screen plate 34 needs to be cleaned or disassembled, the cap 43 can be rotated to loosen it on the surface of the threaded shaft 41. The threaded shaft 41 can be pushed outward to control it to disengage from the clamping plate 42. At this time, the screen frame 31 can be lifted up and opened to allow it to stand upright. At the same time, the screws on the inside of the fixing ring 33 can be removed, making it easier to pull the screen plate 34 to the right out of the screen frame 31.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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 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 claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
