Description

Technical Field

[0001] The utility model relates to the technical field of feed production and processing, in particular to a filtering device for fish feed production. Background Art

[0002] In the process of fish feed production, a screening machine is one of the essential devices, mainly for separating and removing impurities in the feed and screening out coarse materials in the feed. After multiple screenings, the feed particles can be made to have uniform size and better quality.

[0003] The publication number is CN205436277U, and the name is a vibrating screening machine for granular fish feed, which includes a shock-absorbing base, a screening box installed above the shock-absorbing base, a partition board, a filtering screen, a motor, an oscillator, a lift, and a coarse material box. The screening box is divided into a screening chamber and an oscillating chamber by the partition board. The filtering screen includes a first filtering screen and a second filtering screen. The first filtering screen and the second filtering screen are arranged relatively inclined at 30 degrees to 45 degrees in the screening chamber. The top end of the screening chamber is provided with a feed inlet. The first filtering screen and the second filtering screen are both provided with coarse material discharge outlets above the relatively low end in the screening chamber. The coarse material discharge outlets are connected to the coarse material box. One side of the bottom end of the screening chamber is provided with a fine material discharge outlet. The oscillator and the lift are both arranged in the oscillating chamber. One end of the lift is fixedly connected to the partition board. One end of the oscillator abuts against the partition board, and the other end is connected to the motor. The motor is fixed on the shock-absorbing base. The filtering screen is arranged relatively inclined, and the fish feed can automatically slide during the screening process, not easily blocking the filtering screen. At the same time, the oscillator can complete the screening of the fish feed without running at a large power; it has the characteristics of low noise, convenient disassembly and cleaning of the filtering screen, lower cost, and high production efficiency.

[0004] However, for the above-mentioned vibrating screening device for fish feed, the large-particle feed filtered by the filtering screen needs to be dropped and recovered. After recovery, other equipment needs to be used for re-cutting. Since the filtering screen lacks a cutting structure, other equipment needs to be used for cutting, and the recovery and cutting process is relatively cumbersome, and the cutting steps increase, thereby reducing the vibrating screening efficiency of the fish feed.
