Description

Technical Field

[0001] This utility model relates to the technical field of feed screening, specifically to a screening device for eel feed processing. Background Technology

[0002] Eel feed is a specialized formulated feed designed specifically for eel farming. It is high in protein and fat, and rich in vitamins and minerals. Its protein content is typically over 45%, making it a core nutrient for ensuring rapid eel growth and maintaining the normal development of cells, tissues, and organs. However, during industrial production and processing, due to differences in raw material particle size and fluctuations in extrusion or pelleting processes, substandard particles that are too large or too small inevitably appear in the finished product. Once these abnormal particles enter the farming stage, they will directly lead to decreased feeding efficiency, uneven nutrient intake, and even intestinal damage and water quality deterioration in eels.

[0003] According to Chinese Patent No. CN221657127U, a screening device for feed processing is disclosed. This utility model solves the problem that when feed can only be fed in small quantities, once a large amount of feed is fed, due to the large quantity and varying size of the feed, the feed easily accumulates in the feed pipe, clogging the pipe and affecting subsequent feeding, thus reducing screening efficiency. Through the arrangement of a screening box, a rocker plate, a mounting shaft B, an anti-clogging plate, a gear B, a lever, a mounting shaft A, a shaking part, a motor, a rotating shaft A, and a gear A, the motor runs, driving the rotating shaft A to rotate, which in turn drives the gear B to rotate, causing the lever to rotate. When the lever rotates and contacts the rocker plate, the other end of the rocker plate rotates and tilts up around the mounting shaft B, causing the anti-clogging plate to move downward, which can reduce the supporting force on the feed and realize the unblocking of the feed inside the feed pipe.

[0004] However, existing feed screening devices generally adopt a "gravity-feeding" structure, where feed pours down from the inlet and relies solely on gravity to pass through one or more screens. The entire falling process is often completed in a short time, lacking a forced dispersion and retention mechanism, resulting in insufficient feed screening. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the problem that existing feed screening devices generally adopt a "gravity-feeding" structure, in which feed pours down from the inlet and relies solely on gravity to pass through one or more screens. The entire falling process is often completed in a short time, lacking a forced dispersion and retention mechanism, resulting in insufficient feed screening.

[0006] The technical solution adopted to solve the above technical problems is:

[0007] A screening device for eel feed processing includes a screening cylinder with a first screening hole, a second screening hole, and a third screening hole. The diameters of the first, second, and third screening holes increase sequentially, and their heights decrease sequentially. Loading plates are fixed on both sides of the screening cylinder, and the loading plates are rotatably mounted on a fixed support. The left side of the fixed support is lower than the right side. A threaded rod is rotatably connected between the loading plates, and a baffle plate is threaded onto the threaded rod. A limit plate is fixed inside the screening cylinder, and a limit groove is formed on the baffle plate. The limit plate slides within the limit groove of the baffle plate. The screening cylinder is installed at an angle, and the diameters and heights of the three-stage screening holes increase sequentially, forming a "gravity + rotation" composite screening: eel feed particles are automatically graded from small to large inside the cylinder, with broken particles, half-particles, and whole particles being discharged from the first, second, and third screening holes, respectively. The baffle plate can move axially under the drive of the threaded rod.

[0008] As a preferred embodiment of this utility model, a reinforcing rib is fixed on the fixed bracket, and a control panel is installed on the right side of the fixed bracket. The reinforcing rib improves the torsional stiffness of the fixed bracket.

[0009] As a preferred technical solution of this utility model, a support base is fixed on the lower side of the fixed bracket, and a snap-fit ​​plate is fixed on the support base. A loading box is slidably connected inside the snap-fit ​​plate. The loading box is located below the first screening hole, the second screening hole, and the third screening hole. The snap-fit ​​plate prevents the box from shifting due to vibration, realizing "screening and loading immediately", and no additional material receiving trolley is required on site.

[0010] As a preferred embodiment of this utility model, a first rotating motor is fixed on the left side of the fixed bracket, and the first rotating motor drives the screening cylinder to rotate.

[0011] As a preferred embodiment of this utility model, a second rotating motor is fixed on the right side of the loading plate, and a motor bracket is fixed next to the second rotating motor. The motor bracket is rotatably connected to the fixed bracket, and the second rotating motor drives the threaded rod to rotate.

[0012] As a preferred technical solution of this utility model, a mounting plate is fixed to the back of the barrier plate. The mounting plate is circular and a cleaning brush is fixed on the mounting plate. The circular mounting plate moves synchronously with the barrier plate, and the cleaning brush on the back continuously sweeps the inner wall of the screening cylinder to clean the adhering grease and powder in real time, preventing the screen holes from clogging.

[0013] The beneficial effects of this utility model are as follows:

[0014] Because this utility model has a baffle plate threaded inside the screening cylinder, the user can control the screening time of the feed in each screening area by rotating the baffle plate, thereby enabling the feed to be fully screened and avoiding the problems of missed screening and repeated screening caused by the "one-pass" of traditional gravity screens.

[0025] Example 1

[0026] exist Figure 1-4 This utility model provides a technical solution: a screening device for eel feed processing, including a screening cylinder 1. The screening cylinder 1 has a first screening hole 2, a second screening hole 3, and a third screening hole 4. The diameters of the first screening hole 2, the second screening hole 3, and the third screening hole 4 increase sequentially, and their heights decrease sequentially. Loading plates 6 are fixed on both sides of the screening cylinder 1. The loading plates 6 are rotatably mounted on a fixed bracket 5, with the left side of the fixed bracket 5 being lower than the right side. A threaded rod 7 is rotatably connected between the loading plates 6, and a barrier plate 8 is threadedly connected to the threaded rod 7. A limiting plate 9 is fixed inside the screening cylinder 1, and a limiting groove is opened on the baffle plate 8. The limiting plate 9 slides in the limiting groove of the baffle plate 8. The left-low and right-high tilt angle of the fixed bracket 5 makes the screening cylinder 1 tilted. The raw material enters from the high end and moves downward step by step under the action of gravity and rotation. The fine material with a particle size smaller than the first screening hole 2 is screened out first, the medium particle size is discharged from the second screening hole 3, and the largest particle size is discharged from the end of the third screening hole 4, realizing three-level continuous grading. The limiting plate 9 cooperates with the limiting groove to prevent the baffle plate 8 from rotating with the threaded rod 7, ensuring that it only moves along the axial direction, thereby accurately controlling the screening time of each screening area.

[0027] In one aspect of this embodiment, a reinforcing rib 19 is fixed on the fixed bracket 5, a control panel 10 is installed on the right side of the fixed bracket 5, a support base 11 is fixed on the lower side of the fixed bracket 5, a snap-fit ​​plate 12 is fixed on the support base 11, and a loading box 13 is slidably connected inside the snap-fit ​​plate 12. The loading box 13 is located below the first screening hole 2, the second screening hole 3, and the third screening hole 4. The reinforcing rib 19 improves the rigidity of the fixed bracket 5 and reduces screening vibration deformation. The support base 11 lifts the entire machine off the ground for easy bottom maintenance. Materials of different particle sizes fall into the independent loading box 13 below through the corresponding screening holes. The snap-fit ​​plate 12 guides and pulls the material to achieve classified collection and rapid transfer.

[0028] In one aspect of this embodiment, a first rotating motor 14 is fixed to the left side of the fixed bracket 5, which drives the screening cylinder 1 to rotate. A second rotating motor 18 is fixed to the right side of the loading plate 6, and a motor bracket 15 is fixed next to the second rotating motor 18. The motor bracket 15 is rotatably connected to the fixed bracket 5. The second rotating motor 18 drives the threaded rod 7 to rotate. A mounting plate 16 is fixed to the back of the baffle plate 8. The mounting plate 16 is circular, and a cleaning brush 17 is fixed on the mounting plate 16. The first rotating motor 14 drives the screening cylinder 1 to rotate at a low speed, causing the material to tumble continuously. The second rotating motor 18 drives the threaded rod 7 to rotate, causing the baffle plate 8 to move axially and adjust the screening time of each screening area in real time. The cleaning brush 17 moves synchronously with the baffle plate 8, brushing around the screening holes to prevent clogging and ensure continuous and efficient screening.

[0029] The working principle of this utility model is as follows: The left-low, right-high tilt angle of the fixed bracket 5 keeps the screening cylinder 1 in an inclined state; the first rotating motor 14 drives the screening cylinder 1 to rotate at a low speed, and the raw material enters from the high end and moves downward step by step under the action of gravity and rotation. The fine material with a particle size smaller than the first screening hole 2 is screened out first, the medium particle size is discharged from the second screening hole 3, and the largest particle size is discharged from the end of the third screening hole 4, realizing three-level continuous grading. The second rotating motor 18 drives the threaded rod 7 to rotate, which drives the baffle plate 8 to move axially and adjusts the screening time of each screening area in real time; the limiting plate 9 cooperates with the limiting groove to prevent the baffle plate 8 from rotating and ensure that it only moves axially. The cleaning brush 17 moves synchronously with the baffle plate 8 to brush the periphery of the screening hole and prevent the hole from being blocked. The material of each particle size falls into the independent loading box 13 below through the corresponding screening hole. The snap plate 12 guides and pulls it out to realize classified collection and rapid transfer, thereby completing the integrated operation of inclined rotary screening, adjustable screening time, automatic cleaning and classified collection.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
