Description

Technical Field

[0001] This utility model relates to the field of pet food raw material processing technology, and more specifically, it relates to a pet food raw material screening device. Background Technology

[0002] Pet food is food specifically designed for pets and small animals. It is a high-end animal food that falls between human food and traditional livestock feed. Some pet foods are in pellet form. During the pet raising process, there are many different types of pet food. In the processing of pet food, different pellet sizes are produced, so screening equipment is needed to screen the pet food.

[0003] For example, the raw material screening device for pet food processing disclosed in patent announcement number CN220635220U uses a washing mechanism to wash the pet food residues adhering to the screen plate, preventing the residues from becoming moldy and entering the pet food in the subsequent screening process, which helps to improve the quality of pet food and avoids threats to the life and health of pets.

[0004] During operation, workers typically pour the pet food ingredients directly onto the screen through the feeding port. Due to the lack of a proper material control mechanism, this direct pouring leads to uneven accumulation of material on the screen surface. This is especially problematic for denser, more viscous materials, which can easily create dead zones in localized areas, severely reducing the screen's effective filtration area. Furthermore, the piled-up material, under gravity, can cause agglomeration, particularly in high-humidity production environments, where previously loose particles can easily clump together into difficult-to-separate lumps. In such cases, even if the rinsing mechanism removes surface deposits, it cannot solve the problem of incomplete screening caused by material agglomeration. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pet food raw material screening device that facilitates the cleaning and replacement of the sieve plate.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A pet food ingredient sieving device includes a sieving box, a cover, and a vibrating motor. The sieving box contains a sieving mechanism, and the cover has a rinsing mechanism. The screening mechanism includes a screen plate, a feed plate, and a guide plate.

The cover has a feeding port corresponding to the guide plate of the sieve plate, and the inner wall of the screening box has a discharge port corresponding to the lowest point of the discharge plate. The vibrating motors are placed on both sides of the screening box. The rinsing mechanism includes a nozzle and a water pipe connected to the nozzle. The nozzle is located on the lower end face of the cover, and the water pipe is connected to an external water source.

[0007] The present invention is further configured such that: a water inlet hole is provided on the cover, the water inlet hole is fixedly connected to a water guide pipe, the nozzle is detachably connected to the water guide pipe, the nozzle is installed inside the cover and extends downward by means of a threaded connection, and the spraying direction of the nozzle is towards the inner wall of the screening box.

[0008] The present invention is further configured such that: the side wall of the screening box is provided with a loading and unloading port, the inner side of the loading and unloading port is fixedly provided with a sliding groove, the two sides of the screen plate are respectively provided with guide rails that slide with the sliding groove, the end of the screen plate is provided with a sealing door, the sealing door is provided corresponding to the loading and unloading port, a sealing ring is provided between the loading and unloading port and the sealing door, and the end face of the sealing door is provided with a magnet that magnetically attracts the inner wall of the loading and unloading port.

[0011] The present invention is further configured such that a feeding funnel is provided on the feeding port.

[0012] By using a V-shaped guide plate in conjunction with a diversion channel structure, the raw materials are uniformly dispersed in three dimensions, improving screen utilization and eliminating dead zones. The integrated adjustable-angle spray nozzle targeted rinsing system reduces agglomeration and achieves water-saving efficiency. The innovative magnetic quick-release design shortens screen replacement time, and the special V-shaped feeding channel design ensures reduced residue. This solution, combining material dynamics optimization and modular design concepts, not only guarantees screening accuracy and achieves breakthrough improvements in production efficiency and equipment applicability, but also brings significant economic benefits such as reduced overall operating costs.

[0013] By adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. Significantly improves screening uniformity and efficiency: Through the structural design of the V-shaped guide plate combined with the diversion trough, the raw materials are evenly dispersed and form a thin layer during the falling process, which effectively solves the local accumulation problem common in traditional structures, greatly improves the effective utilization rate of the screen, and significantly improves the overall screening speed. It is especially suitable for screening of high-humidity and high-viscosity raw materials. 2. Effectively inhibits material agglomeration and optimizes the cleaning process: The innovative detachable nozzles combined with the water pipe flushing system can flexibly adjust the flushing parameters as needed to form a highly efficient flushing effect, significantly reducing the frequency of material agglomeration. At the same time, it greatly reduces water consumption compared with traditional cleaning methods, ensuring that the equipment always maintains a highly efficient operating state. 3. Significantly improved ease of maintenance: The innovative structural design of the slide rail and magnetic sealing door enables quick replacement and maintenance of the screen plate, which not only greatly reduces equipment downtime, but also significantly improves the overall utilization rate of the equipment and reduces the overall cost of annual maintenance. 4.
