Chalk drying device based on air heater

Abstract

The invention relates to the field of drying equipment, and discloses a chalk drying device based on an air heater. The device is of a workshop-type structure, and brackets for storing chalks are arranged in a workshop. The chalk drying device based on the air heater structurally comprises a cavity formed between an outer wall body and an inner wall body, a plurality of first through holes communicating with the cavity are formed in the inner wall body in an embedded mode, first sleeves are arranged in the first through holes in an embedded mode, and the inner end portions of the first sleevesare connected with dust filtration assemblies through threads; an air inlet is formed in the right side of the outer wall body in an embedded mode, the air inlet is connected with an air outlet pipeof the air heater outside in a sealing mode, and a single-door facilitating in and out is arranged on the left sides of wall bodies; arc-shaped frame beams are arranged on the inner and outer sides ofthe upper end portion of the wall bodies, and an arc-shaped first cover plate is arranged above the arc-shaped frame beams; and a drying area is formed in an area enclosed by the wall bodies, a plurality of chalk storage frames are arranged in the drying area, and a plurality of chalk storage assemblies are arranged on the chalk storage frames. The chalk drying device based on the air heater is simple to operate, convenient to use, and is suitable for multiple places.

Description

technical field [0001] The invention relates to the field of drying equipment, in particular to a chalk drying device based on a hot air blower. Background technique [0002] With the advancement of science and technology and the development of society, the educational facilities in our country have been greatly improved, providing a strong guarantee for the education of young people. At present, chalk is still the main writing tool in the teaching process, and the consumption of chalk in my country is very large every year. [0003] In the process of chalk processing and manufacturing, the chalk is in a wet state after it is made, and usually needs to be dried naturally or with the help of equipment to meet the requirements of the finished product. However, the natural drying time is relatively long, which is not conducive to improving production efficiency; when drying with the help of equipment, the structure of the equipment is underground, specifically laying a number ...

Problems solved by technology

However, the natural drying time is relatively long, which is not conducive to improving production efficiency; when drying with the help of equipment, the structure of the equipment is underground, specifically laying a number of heat dissipation pipes underground, passing steam into the heat dissipation pipes, and passing through the heat dissipation pipes. The rising heat evaporates the moisture in
