Description

Technical Field

[0001] This utility model relates to the field of feed additive preparation, and more specifically, to a filtration device for preparing mixed feed additives. Background Technology

[0002] Feed additives refer to small or trace amounts of substances added during feed production, processing, and use. They are used in very small quantities but have significant effects. During processing, grinding rollers are used to grind and pulverize them. Patent publication number CN219765587U discloses a filtration device for preparing mixed feed additives. This filtration device includes a filter box, characterized by: a collection box at the bottom of the filter box; a filter assembly at the connection between the filter box and the collection box; a pulverizing assembly above the filter assembly; a discharge port on the bottom wall of the collection box; and an anti-wall-hanging structure inside the filter box and the collection box. The anti-wall-hanging structure includes a power assembly A and a power assembly B. A scraper A is located on one side of power assembly A, and a scraper B is located above the filter assembly. A cylinder is located on the top wall inside the filter box, with a movable plate and a sweeping brush at the cylinder's output end, and a distance sensor on one side of the cylinder. The technical problem this invention aims to solve is to provide a filtration device for preparing mixed feed additives that facilitates cleaning of raw materials adhering to the side walls of the device, reducing wall-hanging, improving raw material recovery rate, preventing wall-hanging, and facilitating cleaning.

[0003] In existing technologies, although the above-mentioned filter devices can use brushes to clean the rollers during the crushing process, this cleaning method often results in the brushes shedding bristles after a period of use, causing the raw materials and brushes to mix together. This not only affects the filtration efficiency but also easily leads to impurities in the finished additive raw materials, ultimately affecting the output of the finished product. Therefore, there is a need for a preparatory filter device that can replace brushes for cleaning the raw materials on the rollers. Utility Model Content

[0030] Example 1:

[0031] Please see Figure 1-4 A filtration device for preparing a mixed feed additive includes a filter box 1. A material discharge ramp 2 is integrally formed on the upper inner wall of the filter box 1. A support plate 3 is fixedly installed in the middle of the inner wall of the filter box 1. Elastic sealing rings 4 are fixedly installed at the bottom of the material discharge ramp 2 and the top of the support plate 3. A crushing roller 5 is rotatably installed inside the filter box 1. Air pumps 6 are fixedly installed on both the left and right sides of the crushing roller 5 inside the filter box 1. One end of the air pump 6 is fixedly connected to a ventilation hose 7. One end of the ventilation hose 7 is fixedly connected to an air jet assembly 8. There are two air jet assemblies 8 on the same side. An angle adjustment assembly 9 is slidably installed between the two air jet assemblies 8.

[0032] It should be noted that the filter box 1 in this utility model is the same as the filter box 1 in the prior art. The structure of the top for feeding is the same, and the corresponding connection method and mechanism between the bottom and the collection box are also the same. It belongs to the existing mature technology, so this application will not elaborate on it.

[0033] The jet assembly 8 includes a main jet pipe 801, one end of which is fixedly connected to a nozzle 802. Connecting plates 803 are fixedly installed at both ends of the main jet pipe 801, and limiting rods 804 are fixedly installed on the outer wall of the connecting plates 803. A toothed ring 805 is integrally formed at one end of the connecting plate 803. The limiting rods 804 are rotatably installed on the inner wall of the filter box 1. The air pump 6 is fixedly connected to the two main jet pipes 801 via a ventilation hose 7.

[0034] Specifically, the limiting rod 804 is rotatably installed inside the filter box 1 to provide support for the rotation of both ends of the main pipe 801 and to ensure that the center of rotation is fixed, thus limiting the rotation. Secondly, the flexible nature of the ventilation hose 7 itself allows it to automatically adjust its position when the main pipe 801 rotates, preventing the hose from affecting the rotation. Finally, the air pump 6 provides the total gas input, so that the airflow is sprayed out from the outer end of the nozzle 802 to achieve the purpose of airflow cleaning.

[0035] The angle adjustment assembly 9 includes a main rod 901, with double-sided toothed plates 902 fixedly installed at both ends of the main rod 901. A protruding strip 903 is fixedly installed at the outer end of the double-sided toothed plate 902. A rotating rod 904 is rotatably installed on the outer side of the middle end of the main rod 901. A rotating ring 905 is integrally formed at the outer end of the rotating rod 904. A connecting column 906 is rotatably installed inside the rotating ring 905. A disc 907 is fixedly installed at the bottom end of the connecting column 906. A motor 908 is provided at the bottom end of the disc 907. The output shaft of the motor 908 is fixedly sleeved inside the middle end of the disc 907. The motor 908 is fixedly installed inside the filter box 1. A sliding groove is formed on the inner wall of the filter box 1. The shape of the sliding groove matches the shape of the protruding strip 903. The upper and lower sides of the double-sided toothed plate 902 respectively mesh with the toothed ring 805 at corresponding positions.

[0036] Specifically, the adaptation of the convex strip 903 and the sliding groove limits the horizontal movement of the main rod 901 and the double-sided toothed plate 902, allowing only uniaxial horizontal movement and ensuring stable transmission between them and the toothed ring 805. Finally, the rotational connection between the rotating ring 905 and the two ends of the rotating rod 904 transforms the circular motion of the disk 907 into the linear reciprocating motion of the main rod 901. The rotational connection prevents the angle from changing automatically when the positions of the two ends change accordingly, thus achieving the purpose of preventing mutual exclusion of motion.

[0037] The working principle of this utility model is as follows: When the surface of the crushing roller 5 needs to be cleaned, the air pump 6 is started to draw in air, which is then poured into the ventilation hose 7 and finally passes through the inside of the main pipe 801 to the outside of the nozzle 802 to clean the surface of the crushing roller 5 with airflow. At this time, the motor 908 can also be driven to drive the disc 907 to rotate, which in turn drives the connecting column 906 to rotate. The rotating rod 904 drives the main rod 901 to move back and forth. While the main rod 901 moves back and forth, it also drives the double-sided toothed plate 902 to move. At this time, the double-sided toothed plate 902 drives the toothed ring 805 that meshes with it to rotate, so that the main pipe 801 rotates as a whole, and the spray direction of the nozzle 802 changes, thereby expanding the spray range.

[0038] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
