Description

A kind of clean type hot air circulation heater

Technical field

The utility model relates to a kind of storage heater, relates in particular a kind ofly being applied to plastic cement and five metals shows clean type hot air circulation heater in the spraying coating process.

Background technology

Prior art must have the paint curing operation in plastic cement and five metals surface spray coating process, its effect is exactly will spray the workpiece of getting well in baking oven, by to the heating of environment in the baking oven paint curing with surface of the work.Fierceness along with the progress and the competition of science and technology; the surface of the work spraying of many products requires more and more higher; require the high gloss oil lacquer of spraying through regular meeting; this requires fewer and feweri and more and more littler with regard to the dirt pits that requires surface of the work; and original oven heat equipment; because heat-generating pipe is located in the baking box; air is heated by heat-generating pipe after filtration again; the dust that is produced with heat-generating pipe is attached on the workpiece easily; and because whole baking box space is big; the air temperature is heated inhomogeneous, can't produce the product of rate of good quality at all, and the qualification rate of the finished product of workpiece is low.Existing in prior technology is technological deficiency as mentioned above, become those skilled in the art an anxious big technical problem to be solved.

Summary of the invention

Technical purpose of the present utility model is to overcome in prior art plastic cement and the five metals surface spray coating process, the unreasonable low technical problem of qualification rate that causes the workpiece finished product of Roasting oven structure provides the clean type hot air circulation that a kind of air heat is even, product qualified rate is high heater.

For reaching above technical purpose, the technical solution of the utility model is:

A kind of clean type hot air circulation heater, include baking box, described baking box is provided with air inlet, air inlet is provided with air cleaner, and described air cleaner connects air inlet pipe, and air inlet pipe is connected with heating cabinet, be provided with heating tube in the heating cabinet, one end opening of heating cabinet connects the gas outlet of circulating fan, and the air inlet of described circulating fan connects escape pipe, and described escape pipe connects the gas outlet of baking box; In described baking box, be provided with work rest.

Further, the periphery at described air cleaner is provided with an air filtering box;

Further, in described heating cabinet, be provided with the coarse filtration bag;

Further, between described coarse filtration bag and circulating fan, the shell of heating cabinet is provided with exhaust outlet;

Further, on described escape pipe, also be provided with wind-supplying mouth.

In the utility model, air is at first blown out by the gas outlet of circulating fan, enters heating cabinet, resistance shelves through the coarse filtration bag, the air that contains dust is discharged by exhaust outlet, after the preliminary filtration of air through the coarse filtration bag, and the heating of process heating tube in heating cabinet, become the uniform hot-air of temperature, hot-air enters air inlet pipe, and behind the process high efficiency filter of air cleaner, enters in the baking box in Rose Box, with the baking of the workpiece on the work rest in the baking box, finish the paint curing operation of workpiece; The hot blast of finishing after the operation is discharged by the gas outlet of baking box, and hot blast behind an amount of air of wind-supplying mouth supply, enters the air inlet of circulating fan through escape pipe, circulates next time.

Useful technique effect of the present utility model is: because air is concentrated heating, make being heated of air more even, and pass through before the heating and the double filtration after the heating, air is more pure, when toasting workpiece, can improve the qualification rate of workpiece; After using the utility model structure, yields is brought up to more than 85% by original about 50%, and the utility model design is ingenious, simple in structure, and technology maturation is easy to implement.

Description of drawings

Accompanying drawing 1 is the structural representation of an embodiment of the utility model; The direction of arrow is represented the flow direction of air among the figure.

The specific embodiment

Below in conjunction with accompanying drawing 1, describe the specific embodiment of the present utility model in detail, but present embodiment only is a preference of the present utility model, claim is not done any qualification.

In the structure of the utility model clean type hot air circulation heater, include baking box 100, described baking box 100 is provided with two air inlets 110, air inlet 110 is provided with air cleaner 112, air cleaner 112 peripheries are provided with air filtering box 111, and described air cleaner 112 and air filtering box 111 are communicated with air inlet pipe 101, and air inlet pipe 101 is connected with heating cabinet 121, be provided with heating tube 122 in the heating cabinet 121, heating tube 122 connects the power supply heating; One end opening of heating cabinet 121 connects the gas outlet of circulating fan 105, in the heating cabinet 121, is provided with the coarse filtration bag 123 of filtered air; On heating cabinet 121 shells between coarse filtration bag 123 and circulating fan 105 gas outlets, be provided with exhaust outlet 104; The air inlet of circulating fan 105 connects escape pipe 102, and described escape pipe 102 connects the gas outlet of baking box 100; In described baking box 100, be provided with work rest 103.On escape pipe 102,, also be provided with wind-supplying mouth 106 with the approaching place of the air inlet of circulating fan 105.

In the workflow of the utility model clean type hot air circulation heater, air is at first blown out by the gas outlet of circulating fan 105, enter in the heating cabinet 121, resistance shelves through coarse filtration bag 123, the air that contains dust is discharged by exhaust outlet 104, after the preliminary filtration of air through coarse filtration bag 123, the heating of process heating tube 122 in heating cabinet 121, become the uniform hot-air of temperature, hot-air enters air inlet pipe 101, and behind the process high efficiency filter of air cleaner 112, enters in the baking box 100 in Rose Box 111, with the baking of the workpiece on the work rest 103 in the baking box 100, finish the paint curing operation of workpiece; The hot blast of finishing after the operation is discharged by the gas outlet of baking box 100, and hot blast behind an amount of air of wind-supplying mouth 106 supplies, enters the air inlet of circulating fan 105 through escape pipe 102, circulates next time.

In a word, in the structure of the present utility model, the heat-generating pipe that originally was in baking box 100 inside is removed, air is concentrated heating; Make being heated of air more even, and by reaching double filtration and a certain amount of hot air circulation after heating before the heating, hot-air is more pure, has guaranteed the air cleaning grade in the baking box, in baking during workpiece, satisfied the requirement of producing high-quality product and improved the qualification rate of workpiece; Be that one of this area is improved greatly.
