Multifunctional stirring machine

Abstract

The invention relates to a multifunctional stirring machine which consists of a rotatable vertical cylindrical container and a stirrer capable of rotating in reverse direction in the container. The structural design that a rotating shaft center of the container and the rotating shaft center of the stirrer are eccentric and a scraper mechanism which is specially arranged can ensure that the multifunctional stirring machine has no stirring dead angles during the work, and an electrical material level automatic control device can ensure the discharge flow of materials by relying on the self-gravity and simultaneously maintain the stable material level in the container. The multifunctional stirring machine can have a plurality of functions of mixing, peeling, clearing, polishing, dampening andthe like by being matched with stirring rods with different structures. When the multifunctional stirring machine is used as a mixing machine, the multifunctional stirring machine has the advantagesof simple structure, low cost, fast mixing speed, high mixing uniformity, small segregation tendency, low energy consumption, simple use and maintenance, long service life and the like. When the multifunctional stirring machine is used as a peeling machine, a clearing machine or a polishing machine, the multifunctional stirring machine has the advantages of high peeling efficiency or good clearingeffect, no production of crushed particles, low energy consumption and the like. When the multifunctional stirring machine is used as a dampening machine, the multifunctional stirring machine has theadvantages of uniform dampening, low energy consumption and the like.

Description

technical field [0001] The invention relates to a multifunctional mixer, which is suitable for grain processing, feed, chemical industry, medicine, food, plastics and building materials and other industries and is widely used for mixing solid particles or powdery materials, peeling grain grains, cleaning the surface of solid granular materials, Polishing and mixing of solid granular or powdery materials and liquid materials. Background technique [0002] In theory, the operation of uniformly blending materials in any state (solid, liquid, gaseous and semi-liquid) is called mixing, but it is customary to call the operation of mixing solid materials and humidifying solid materials as mixing; The operation of mixing solid, liquid or gaseous materials with liquid materials is called stirring. Stirring equipment is composed of frame, container, transmission mechanism, stirring shaft and stirrer (impeller or paddle). At present, there are many types of mixing equipment widely us...

AI Technical Summary

Problems solved by technology

In the process of mixing materials, the equipment must stir a large amount of materials repeatedly to achieve the purpose of full mixing, so the energy consumption of the equipment must be high

In addition, from the analysis of the mixing mechanism, in the mixing process of various types of mixing equipment, the action intensity is high, the mixing effect is good, and the negative effect of segregation tendency will inevitably appear. The effect is not good for materials with large differences in properties such as density and fluidity

Although the intermittent mixing equipment widely used in various industries has the advantages of various varieties, strong adaptability and stable and reliable mixing uniformity, it also has the advantages of large container volume, large floor area, and segregation during storage and transportation after uniform mixing. Phenomenon, can not adapt to continuous and automatic production needs and easy to pollute the environment when unloading and other shortcomings

Although the existing few types of continuous mixing equipment have the advantages of compact structure, less segregation, and can adapt to continuous and automatic production requirements and reduce environmental pollution, they also have poor adaptability (not suitable for use in large differences in particle size, density, shape, etc.) Occasions where the solid materials are mixed with each other) and the lack of mixing uniformity is not high and unstable

[0005] 2. The structural characteristics and defects of the existing peeling machine

Because grain grains generally have characteristics such as different sizes, different shapes, and large differences in anti-destructive strength that cannot be adapted to the structure and working principle of existing peeling machines, all existing peeling machines including rice mills generally have the characteristics of High consumption, incomplete peeling and easy to produce defects such as broken grains

[0007] 3. Structural features and deficiencies of existing threshing machines (surface cleaning equipment)

Because the strength of the wheat grains is different, the momentary force of the threshing machine hitting the wheat grains is relatively large, and the wheat threshing machine rotor must push the wheat from the equipment inlet to the outlet to complete the cleaning task when the wheat is beaten repeatedly. Factors, so the existing wheat thresher has many wearing parts, a small amount of broken grains and high energy consumption will be produced during the working process.

[0009] 4. Structural characteristics and defects of rice polishing machine

The structure of the polishing machine used in the rice milling industry is similar to that of the rice milling machine, so it also has disadvantages such as high energy consumption, uneven friction, difficult operation and control, and easy generation of broken grains.

[0011] 5. The structural characteristics and defects of the existing water machine (liquid-solid mixing equipment)

Obviously, the method of concentrated water injection by water pipes increases the workload, and pushing all the materials from the feed port of the water dispenser to the discharge port is also an additional workload. These two design deficiencies lead to the existing water dispenser being large in size and occupying a lot of space. Disadvantages such as large area and high energy consumption
