Description

Screening plant of solid-state mixed feed additive Technical Field The utility model relates to the technical field of feed additive production equipment, in particular to a screening device for solid mixed feed additives. Background The feed additive is a small amount or trace amount of substances added in the production, processing and using processes of the feed, has little use amount but obvious effect in the feed, is a necessarily used raw material in the modern feed industry, and has obvious effects on strengthening the nutrition value of basic feed, improving the production performance of animals, ensuring the health of the animals, saving the cost of the feed, improving the quality of animal products and the like. Because some feed additives cannot be directly added into feed, one or more feed additives are mixed with a carrier or a diluent according to a specific proportion through processes such as dilution, crushing, drying and the like, so that the fluidity, the dispersibility and the consistency of the feed additives are improved, and the solid mixed feed additive is obtained, so that the requirements of feed processing are met. The solid mixed feed additive obtained by mixing cannot immediately enter a packaging process, and needs to be screened according to the particle size, so that massive impurities or other foreign matters mixed in the production process can be removed, and the quality stability of the final product is ensured. The particle size of the feed additive can be ensured to meet specific requirements, and the effect of ingestion and digestion and absorption of animals due to the too large or too small particle size are avoided, so that the uniformity and effectiveness of the feed additive in the subsequent use process are ensured. At present, a screening device is mainly used for screening solid mixed feed additives, but the existing screening device has the following problems in the actual use process: 1) The existing screening device can only perform primary screening operation on the feed additive, if the feed additive needs to be screened into a plurality of particle sizes, a plurality of screening devices with screens with different meshes are needed, or screens with different meshes are replaced on the same screening device for multiple times, so that the operation is inconvenient, and the screening efficiency is affected; 2) The existing screening device is inconvenient to clean the screen, if different types of feed additives are required to be screened, the screen which is not cleaned is easy to cause cross contamination, so that the purity of a final product cannot be ensured, in the long-time use process, the screen is easy to be blocked by the feed additives, and the screening efficiency and the screening effect can be influenced by irregular cleaning. Disclosure of utility model The utility model aims to provide a screening device for solid mixed feed additives, which aims to solve the technical problems that the screening device in the prior art is inconvenient to clean a screen, and screening efficiency and effect are affected. In order to achieve the above purpose, the utility model adopts the following technical scheme: a screening device for solid mixed feed additives comprises a frame and a screening box which is slidably connected to the frame, wherein a driving mechanism is arranged on the frame and used for driving the screening box to reciprocate linearly, the top of the screening box is communicated with a feed hopper, the bottom and one side of the screening box are opened, one side of the opening of the screening box is hinged with a box door, two side walls of the screening box, which are close to the box door, are provided with a plurality of connecting grooves from top to bottom, the connecting grooves on the two side walls are arranged one by one, two opposite connecting grooves are in sliding connection with a screen mesh, the mesh number of the screen mesh is gradually increased from top to bottom, after the box door is closed, one side of the screen mesh is propped against the box door, and the other three sides of the screen mesh are propped against the side walls of the screening box. The principle and the advantages of the scheme are as follows: During practical application, the feed additive to be screened is added into the screening box through the feed hopper, the driving mechanism is started, the screening box is driven to do linear reciprocating motion through the driving mechanism, screening of the feed additive in the screening box is achieved, materials with particle sizes larger than the aperture of the first layer of screen mesh from top to bottom are reserved on the first layer of screen mesh, the rest materials penetrate through the first layer of screen mesh to drop downwards, the materials with particle sizes larger than the aperture of the second layer of screen mesh from top to bottom are reserved on the second layer of screen
