Drying device for heat insulation plate

Abstract

The invention discloses a drying device for a heat insulation plate. The drying device includes a box body, a base and a transmission mechanism; the box body is located at the top of the base, an inner cavity of the box body is divided into a pre-drying room, a drying room and a heat dissipation room through a partition plate, a feeding opening is formed in the left side wall of the pre-drying room, a discharging opening is formed in the right side wall of the heat dissipation room, motor boxes are arranged in the top of the box body and the base, a heat dissipation motor is arranged in an inner cavity of each motor box, and a rotating shaft is arranged at the power output end of each heat dissipation motor; and a fan blade is arranged at the end, located in the inner cavity of the box body, of each rotating shaft, electric telescopic rods are symmetrically arranged at the top and the bottom of the inner cavity of the drying room, base seats are arranged on the side, attached to each other, of the two sets of electric telescopic rods, microwave generators are arranged on the sides, attached to each other, of the base seats, heat exchange fans are arranged on the left and right sidewalls of the pre-drying room and the right side wall of the heat dissipation room, and a supporting column is arranged in the base. The drying device can reuse the heat discharged by electromagneticheating to dry the heat insulation plate for the first time, the drying effect is better, and the energy is saved.

Description

technical field [0001] The invention relates to the technical field of heat preservation board processing, in particular to a heat preservation board drying device. Background technique [0002] The thermal insulation board is made of polystyrene resin as raw material plus other raw and auxiliary materials and polymers. After heating and mixing, the catalyst is injected at the same time, and then extruded to form a rigid foam plastic board. It has moisture-proof and waterproof properties. Due to the price of the thermal insulation board Affordable, the use of insulation boards is increasing continuously, and during the production and processing of insulation boards, it is necessary to dry and shape the insulation boards. [0003] The application number is 201721280626.8, and the patent name is a new type of multifunctional polystyrene insulation board microwave drying equipment, including the main body of the drying chamber, the base, the transmission motor, the baffle, the ...

Problems solved by technology

[0004] However, during the microwave heating process of this device, a large amount of heat will be generated and directly emitted into the atmosphere, which not only wastes a lot of energy, but also has a certain impact on the environment; this device directly places the insulation board on the large track plane It is not conducive to heat exchange and drying between the bottom of the insulation board and the air, resulting in moisture residue at the bottom of the insulation board. For this reason, we propose a drying device for insulation boards
