Constant-temperature draught fan used on conveying belt of spraying equipment

Abstract

The invention relates to a constant-temperature draught fan used on a conveying belt of spraying equipment, and belongs to the field of draught fans. The constant-temperature draught fan comprises a refrigeration main case. Air curtain machines are arranged at an air inlet and an air outlet of the refrigeration main case. A plurality of outer rotor motors are arranged at the bottom of the refrigeration main case in parallel. An evaporator and a condenser are arranged in the refrigeration main case. Heating pipes are laid in the evaporator and connected with an outer electric control box. A heat preservation box body is arranged below the refrigeration main case and erected on the conveying belt of the spraying equipment, so that the air direction is perpendicular to the moving direction of the conveying belt. A temperature control switch is arranged in the electric control box and connected with a temperature sensor. According to the constant-temperature draught fan, the optimal air supply temperature can be provided for sprayed articles according to the environment temperature, and energy consumption is low.

Description

technical field [0001] The invention relates to the field of fans, in particular to a constant temperature fan used on the conveyor belt of spraying equipment. Background technique [0002] In the prior art, there is no dedicated blower for spraying and drying on the spraying equipment. Mobile air conditioners are used to blow cold air to the sprayed items on the side of the conveyor belt to cool down. The best spraying temperature of the sprayed items needs to be between 25°C- Between 28°C, this method has poor cooling effect in summer, and the temperature is too low in winter to meet the requirements of drying, and the air conditioner is installed on the side of the conveyor belt of the spraying equipment, which occupies the working space and hinders the spraying operation. [0003] Moreover, the mobile air conditioner uses unshielded side air to directly blow the sprayed items to cool down, the cooling effect is uneven, the cooling effect is not ideal, the cold air blown ...

[0002] In the prior art, there is no special blower for spraying and drying on the spraying equipment. Mobile air conditioners are used to blow cold air to the sprayed items on the side of the conveyor belt to cool down. The best spraying temperature of the sprayed items needs to be between 25°C- Between 28°C, this method has poor cooling effect in summer, and the temperature is too low in winter to meet the requirements of drying, and the air conditioner is installed on the side of the conveyor belt of the spraying equipment, which occupies the working space and hinders the spraying operation

[0003] Moreover, the mobile air conditioner uses unshielded side air to directly blow the sprayed items to cool down, the cooling effect is uneven, the cooling effect is not ideal, the cold air blown out is directly exposed to the air, and the energy consumption is too high; moreover, without hot air, it cannot be used in winter
