Technical field
The utility model relates to a kind of automatic moisture content drying system, specifically, relates to a kind of spraying process that is used for product surface moisture content is controlled the device of oven dry automatically, belongs to the application techniques field.
Background technology
At present, at the known moisture content drying unit of coating equipment technical field, mainly comprise heater, air-supply arrangement, exhaust pipe device etc.The moisture content drying unit of this type has following weak point: 1) early stage to do a large amount of preparations in oven dry, need in the drying course operating personnel see constantly to, manually control room temperature, need to consume a large amount of manpowers and time; 2) drying rate is slow, and operating efficiency is low, and dries quantity is not high; 3) noise is big in the drying course, toxic emission is many, and environment has been caused certain pollution.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of automatic control spraying drying unit is provided.
Automatic control spraying drying unit of the present utility model comprises the air curtain system, drying system, hot air circulating system and the waste discharge system that link to each other successively;
Preferably,
In the automatic control spraying drying unit of the present utility model, said air curtain system is the warm air curtain system, comprises the filter that is located at its porch, is located at its inner heater and thermostat, is located at the elastic dampers and the dissipative muffler of its bottom.Filter can effectively filter diameter in the air 〉=10um grit, heater can be to adding thermal control through distinguished and admirable, thermostat can be regulated the control air themperature automatically, elastic dampers can alleviate vibrations, thereby prolong the working life of air curtain system, dissipative muffler can reduce noise, reaches quiet effect.
Said drying system comprises drying chamber, be located at the blower skeleton and the bleed pipe of drying chamber inside and be located at the heat-insulation layer of drying chamber outside.The winding-up pipe evenly sprays thermal air current, and workpiece is toasted.Heat-insulation layer is the insulation filled board that heat insulating material constitutes, and is heat bridge on thermal structure, and many holes are arranged on the liner plate, can reduce the exchange heat of inner and outer plates, reaches desirable heat insulation effect.
In the automatic control spraying drying unit of the present utility model, said hot air circulating system comprises aspiration channel and blower, and aspiration channel wherein links to each other with drying system, and blower links to each other with the waste discharge system.
In the automatic control spraying drying unit of the present utility model, said waste discharge system comprises blast pipe, be positioned at the blast cap at blast pipe top and be located at the manually-operated gate of exhaust pipe lower part.Manually-operated gate is used for the control to the spacing discharging of waste gas minimal security, and blast cap is used for anti-rainwater and the dirt matter blast pipe that bleeds.
Automatic control spraying drying unit of the present utility model has following technique effect:
1) simple in structure, working service convenience;
2) drying rate is fast, effective and automatic degree is higher;
3) homogeneous heating, the bake out temperature adjustable extent is big
4) noise is few in the drying course, waste gas is few, energy-conserving and environment-protective.
