Drying and pelletizing device for chemical engineering

Abstract

The invention discloses a drying and pelletizing device for chemical engineering. The drying and pelletizing device comprises two supporting bases, a rotary barrel, a steam pipe coil and a motor; thetwo ends of the rotary barrel are each provided with a connecting end, and the rotary barrel are rotationally connected with the two supporting bases through the two connecting ends; the steam pipe coil is tightly attached to the inner wall of the rotary barrel and is arranged in the axis direction of the rotary barrel spirally, and the two ends of the steam pipe coil are communicated with a steam inlet pipe and a steam outlet pipe corresponding; a plurality of fins are arranged on the steam pipe coil in the spiral direction, the roots of the fins are internally provided with fin cavities communicated with hollow runners, and the ends of the fins are fin blades with the isosceles triangle cross sections; the rotary barrel is provided with a material inlet and a material outlet; and the output end of the motor is connected with the connecting end of a chain, and the rotary barrel is further driven to rotate. The drying device is simple in structure, reasonable in design, even in material heating, and capable of conducting cutting and pelletizing while drying operation is carried out; and the equipment is high in systematicness, good in drying effect and high in production efficiency.

Description

technical field [0001] The invention relates to a chemical drying and granulating device. Background technique [0002] In the process of chemical production, a large number of heating, drying and granulation devices are needed. The existing technology is not systematic, the production continuity is not strong, and the production efficiency is low. In addition, in the prior art granulation process, the screen is easy to block , the sieving efficiency is not high, and there is a large dust pollution, which will cause certain harm to the staff. In the existing material drying equipment, its main body is usually a box structure, with an inlet at one end and an outlet at the other end, and a drying channel between the inlet and the outlet.

[0002] In the process of chemical production, a large number of heating, drying and granulation devices are needed. The existing technology is not systematic, the production continuity is not strong, and the production efficiency is low. In addition, in the prior art granulation process, the screen is easy to block , the sieving efficiency is not high, and there is a large dust pollution, causing certain harm to the staff

In the existing material drying equipment, its main body is usually a box structure, with an inlet at one end and an outlet at the other end, and a drying channel between the inlet and the outlet. Wheel transmission mechanism and heater, use the heater to heat the drying belt, and use the belt wheel transmission mechanism to transfer the material to the drying channel, so as to achieve the purpose of heating and drying the material, although this method can dry the material However, in order to ensure the drying effect of the material, the thickness of the material to be dried each time should not be too thick, and the drying efficiency is low; and to ensure a good drying effect on the basis of high drying efficiency, the thickness of the dried material cannot be made Afterwards, therefore, it is necessary to increase the power of the heater and speed up the transmission efficiency of the pulley transmission mechanism. This method also has the defects of wasting energy, time and labor, and the material may also be heated unevenly, and the drying effect of the material is not good. First, even some materials undergo qualitative changes at excessively high temperatures
