Description

Technical Field

[0001] This utility model relates to the technical field of processing and mixing devices, specifically to a processing and mixing device for uniformly mixing compound rumen-protected nutritional preparations for sheep. Background Technology

[0002] In the process of uniformly formulating compound rumen-protected nutritional preparations for meat sheep, a processing and mixing device is required to cut and fully mix the feed components, ensuring uniform formulation of the nutritional preparations.

[0003] Traditional processing and mixing devices for uniformly distributing compound rumen-protected nutritional preparations to sheep can only generate the main flow through conventional spiral blades or paddles. For materials with significant differences in density, particle size, oiliness, or viscosity, such as powders, granules, and oil-coated microparticles, clumping, segregation, and dead zones are easily generated, making it impossible to achieve true three-dimensional all-round uniform mixing. This results in insufficient mixing uniformity and the existence of dead zones. Therefore, there is an urgent need for processing and mixing devices for uniformly distributing compound rumen-protected nutritional preparations to sheep to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a processing and mixing device for uniformly distributing compound rumen-protected nutritional preparations for mutton sheep, in order to solve the problem mentioned in the background art. Traditional processing and mixing devices for uniformly distributing compound rumen-protected nutritional preparations for mutton sheep can only generate the main flow when in use, through traditional spiral blades or paddles. For materials with huge differences in density, particle size, oiliness or viscosity, such as powder, granules, and oil-coated microparticles, clumping, segregation and dead corners are easy to occur, making it impossible to achieve true three-dimensional all-round uniform mixing, resulting in insufficient mixing uniformity and dead corner problems.

[0016] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. In the embodiments of the present utility model, the different types of cross-sectional lines are not labeled according to national standards, nor do they specify material requirements for the components; they are used to distinguish the cross-sectional views of the components in the drawings.

[0017] Please see Figure 1-5 A processing and mixing device for uniformly dispensing compound rumen-protected nutritional preparations for mutton sheep includes a shell 1. Support legs 2 are connected to both sides of the bottom of the shell 1. A mixing chamber 3 is located inside the shell 1. The bottom sides of the mixing chamber 3 are connected to the inner bottom of the shell 1 via columns 7. An inlet 4 is inserted into the upper left end of the shell 1, and the bottom of the inlet 4 communicates with the upper left end of the mixing chamber 3. A discharge port 5 is located at the bottom of the mixing chamber 3, and its lower end passes through the bottom of the shell 1 and extends downwards. A discharge valve 6 is installed on the discharge port 5. A stirring motor 9 is installed on the top of the shell 1. The output shaft of the stirring motor 9 passes through the top of the shell 1 and the mixing chamber 3 and is connected by a coupling. The lower end of the coupling 10 is connected to the stirring shaft 14. Scrapers 11 are connected to both sides of the upper end of the stirring shaft 14. A ribbon-shaped spiral blade 12 is provided at the middle end of the stirring shaft 14, and a shearing blade 13 is provided at the bottom of the stirring shaft 14. By installing stirring blades of different shapes in layers along the axial direction on the stirring shaft 14, the lower layer is a blade with strong shearing action to break up agglomerates, the middle layer is a ribbon-shaped spiral blade 12 to promote the axial circulation of materials, and the upper layer is an anchor scraper 11 close to the inner wall of the mixing chamber 3 to scrape off adhering materials and induce radial tumbling. This combination realizes the synergy of three mixing mechanisms: shearing, convection and diffusion, resulting in high mixing uniformity and no dead corners.

[0018] The number of columns 7 is set to four, and the four columns 7 are arranged in pairs facing each other about the bottom of the mixing chamber 3.

[0019] The number of support feet 2 is set to four, and the four support feet 2 are arranged in pairs facing each other about the bottom of the housing 1.

[0020] A support frame 15 is connected to the side wall of the feed inlet 4. A vibration motor 16 is installed on one side of the support frame 15. The vibration motor 16, which is connected to the side wall of the feed inlet 4 through the support frame 15, can be started during feeding and mixing. Its vibration can effectively prevent sticky materials from bridging or blocking at the feed inlet 4 and the screen 8, ensuring that the raw materials enter the mixing chamber 3 smoothly and continuously.

[0021] The feed inlet 4 is located to the left of the stirring motor 9.

[0022] The two scrapers 11 are arranged symmetrically about the stirring shaft 14.

[0023] The scraper 11 is close to the inner wall of the mixing chamber 3, but not connected to it.

[0024] The feed inlet 4 has a screen 8 installed inside.

[0025] The working principle and usage process of this utility model are as follows: First, various powdery, granular, or trace liquid rumen-protected nutritional preparation raw materials to be mixed are fed into the device through the feed inlet 4. The screen 8 installed inside the feed inlet 4 can perform preliminary screening of the input raw materials to prevent larger foreign objects or clumps from entering the mixing chamber 3, ensuring the subsequent mixing quality and equipment safety. The vibration motor 16, which is connected to the side wall of the feed inlet 4 through the support frame 15, can be started during the feeding and mixing process. Its vibration can effectively prevent sticky materials from bridging or blocking at the feed inlet and the screen, ensuring that the raw materials enter the mixing chamber 3 smoothly and continuously.

[0026] The shear blades 13 at the bottom of the stirring shaft 14 rotate at a high linear speed, applying a strong mechanical shearing force to the material. This is specifically designed to strongly disperse and break down nutrient preparation raw materials (such as damp starch and protein powder) that are prone to absorbing moisture and clumping. The main purpose is to achieve shear mixing by destroying the aggregate structure of the material, causing the material particles to slide and separate from each other, thereby achieving microscopic uniformity. The middle layer of spiral blades 12 is equivalent to a continuous spiral conveyor belt, which generates a strong axial thrust, continuously lifting the material that has undergone bottom shearing from the bottom of the mixing chamber 3 upwards, or pressing it downwards according to the spiral direction, thus pushing the material to axially circulate. This breaks the tendency of the material to naturally stratify due to gravity. Driven by the spiral blades, a macroscopic and continuous material circulation flow is formed in the mixing chamber 3, mainly to achieve convective mixing, so that the material can carry out a large-scale and overall position exchange in the mixing chamber 3. This is the key to eliminating mixing dead zones and achieving rapid macroscopic uniformity. The two upper scrapers 11 are symmetrically arranged about the stirring shaft 14. Their outlines are close to the inner wall of the mixing chamber 3, but they are not connected to each other to avoid excessive frictional resistance. During the mixing process, materials containing viscous components such as oil or sugar are very easy to adhere to the inner wall of the mixing chamber, forming dead material that does not participate in the mixing. As the scraper 11 rotates with the shaft, it can scrape off these adhered materials in time and return them to the active mixing area. The movement of the scraper 11 not only scrapes the wall, but also applies a tangential force to the material near the wall, forcing the material to move towards the central area and merge with the material rising or falling from the center, thereby forming a strong radial tumbling motion in the cross-section of the mixing chamber. After the mixing process is completed, the discharge valve 6 installed on the discharge port 5 is activated. The well-mixed finished product is discharged from the bottom of the mixing chamber 3 through the discharge port 5 under the action of gravity. The discharge valve 6 can control the opening and closing of the discharge and the flow rate. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0027] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
