a honeycomb grinder

Abstract

The invention discloses a honeycomb grinder which comprises a machine seat and an air chamber arranged on the machine seat, wherein the air chamber comprises a honeycomb grinder shell, a main shaft passing through the honeycomb grinder shell, and a dispersion wheel arranged on the main shaft; the main shaft is driven to rotate by a first driving motor arranged on the machine seat; the honeycomb grinder also comprises a depolymerization bin arranged at the upper part of the air chamber; the depolymerization bin is internally provided with a plurality of depolymerization wheel bodies sheathed on the main shaft; the top of the honeycomb grinder shell is provided with a center hole communicated with the depolymerization bin; the main shaft passes through the center hole. According to the honeycomb grinder, material and hot air firstly enter the air chamber, the material is evenly distributed in the hot air in the high-speed rotation process, the water of the material is well evaporated, fine particles are formed by the crude material which is impacted at the edge of the honeycomb grinder under the action of centrifugal force, and the fine particles are sucked into the depolymerization bin in the middle of vortex under the action of centrifugal force. In the depolymerization bin, the material can be rapidly ground into superfine powder by the rotation of the depolymerization wheel bodies.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a honeycomb mill. Background technique [0002] At present, there are many similar drying equipment on the market, such as ovens, belt dryers, rotary drum dryers, fluidized bed dryers, airflow dryers, spray dryers, powerful crushing dryers, centrifugal dryers, and spray towers. Although they are different in terms of structural principle, structural form and scope of application, they have one thing in common and can have a single drying function or a simple dispersing function. However, more than two functions cannot be realized simultaneously, which limits the development of the industry and the needs of customers. [0003] In many industries, the powder needs to be dried after ultra-fine grinding. For example, after wet ultra-fine grinding, it is easy to form lumps and cannot be restored to the particle size after wet grinding. It is necessary to increase the dispers...

AI Technical Summary

Problems solved by technology

[0006] In the existing equipment, the hot air and materials enter the equipment separately, and the hot air cannot be used to preheat the materials when the pipeline flows, which wastes a lot of heat energy

However, the existing equipment cannot effectively break up the agglomerated materials because the hot air enters the equipment from a place lower than the feed inlet, the material particles are large, the moisture content is high, there is no pre-drying, the surface area is small, and the particles formed by material agglomeration The outside is suddenly heated by hot air, and the moisture on the surface quickly evaporates and dries up. The moisture inside the particles cannot be released due to the dry conjunctiva formed by the evaporation of surface moisture, forming agglomerated particles that cannot be broken up. This is why the drying efficiency of the current equipment is low. The root cause of poor dispersion reduction and low modification rate

[0007] In addition, hot air and materials enter the equipment tangentially from the side of the equipment, and one side of the equipment is impacted by materials and hot air, resulting in unstable operation, increased failure rate, and damage to the operation of bearings and main shafts. Therefore, the design of the transmission system of the equipment Complicated, need auxiliary cooling, lubrication system

[0008] In order to overcome the above problems, many manufacturers purchase single-function equipment separately, resulting in a long production line with many equipment for these complex processes, long process flow, many equipment, large floor area, large energy consumption, complicated operation, and difficult process. Difficult to adjust, cannot guarantee the quality and quality of the product
