Composite type multilayer spiral vibrating countercurrent drying machine

Abstract

The invention relates to a composite type multilayer spiral vibrating countercurrent drying machine. The composite type multilayer spiral vibrating countercurrent drying machine comprises a pluralityof drying discs, and the multiple drying discs are arranged in a stacked mode to form a drying box body; the drying box body is mounted on a base, a vibrating motor is mounted in the base, and the drying discs comprise boxes, heat preservation layers, screening plates, spiral sheets, material falling openings and material falling grooves; the drying disc on the top layer is provided with a feedingcabin and an air outlet, the air outlet is provided with a temperature sensor, and an automatic feeding device is mounted on the feeding cabin; the drying disc on the bottom layer is provided with anair inlet, the air inlet is connected with an air inlet tube, and a temperature sensor is arranged in the air inlet tube; and the drying disc on the bottom layer is further provided with a discharging cabin, the air inlet tube is connected with air inlet equipment, and the air inlet equipment comprises a blower, a heater and an air filter, wherein the blower, the heater and the air filter are arranged sequentially in the flow direction of air. According to the composite type multilayer spiral vibrating countercurrent drying machine, materials and hot air flow in the reverse direction, the heat efficiency is extremely high, the drying efficiency is improved, and the problem that the materials are accumulated and thus difficult to clean is solved.

Description

technical field [0001] The invention relates to a composite multi-layer spiral vibrating countercurrent dryer, which is suitable for drying technical fields of various pills of traditional Chinese medicine, such as honey pills, water pills, concentrated pills, dripping pills, etc., and is suitable for pharmaceutical, chemical, food, feed, plastic, etc The drying technology field of granular materials in the industry is suitable for the drying technology field of materials such as short strips, granules, blocks, and spheres. Background technique [0002] The vibrating dryer is mainly suitable for drying bulk and granular materials in chemical, pharmaceutical, food, grain, mining and other industries. At present, the spiral drying equipment used on a large scale in China is subject to the problem of hot air transportation, the temperature is unstable, and the hot air is easy to lose. The result is high energy consumption, low thermal efficiency, and environmental pollution. ...

AI Technical Summary

Problems solved by technology

The result is high energy consumption, low thermal efficiency, and environmental pollution.

Therefore, the disadvantages of high energy consumption, low thermal efficiency, and high maintenance costs limit the use of these devices.

[0003] At present, the spiral drying equipment used on a large scale in China is subject to unreasonable structure and technology, and the detail design is not perfect. As a result, the internal materials of the drying equipment are easy to accumulate, resulting in the surface being dried and excessive moisture inside, which affects the overall drying effect.

At the same time, the material damage rate is high, (especially the pills) are poorly formed, and it is not easy to clean and clean the machine.

Therefore, the disadvantages of high material damage rate, poor drying effect, and difficult cleaning limit the use of these equipment.

[0004] Therefore, it is extremely important to solve the problems of thermal efficiency, temperature control, high material damage rate, poor drying effect and difficult cleaning and maintenance in the drying process of materials.
