Description

Manual electrostatic precipitator

technical field

The utility model relates to a mechanical device for electrostatic dust removal, in particular to a manual electrostatic dust removal equipment.

Background technique

In plastic spraying, plastic workpieces will generate static electricity due to factors such as temperature and air during handling operations. Static electricity will adsorb dust in the air to the workpiece and affect the spraying effect of the workpiece. This has always affected the accuracy and appearance of the workpiece in plastic spraying. with the biggest factor of quality.

At present, pre-treatment electrostatic dust removal mainly includes manual air gun dust removal, water shower dust removal, wiping dust removal and direct electrostatic dust removal.

Manual air gun dust blowing: Use an air gun or air pipe to directly act on the surface of the workpiece for dust removal. This method can blow away most of the dust attached to the workpiece, but it has no effect on small attached crops, especially electrostatically attached dust; at the same time, The dust blown away is easy to attach to the workpiece again, and has no direct effect on the pre-spraying treatment required by the refinement standard.

Water dedusting: the high-pressure water acts on the surface of the workpiece, which can wash away most of the dust attached to the workpiece, but the disadvantage is that pre-drying treatment is required, and it is easily polluted by dust attachments in the air.

Wipe and remove dust: use professional wipe paper or cloth to wipe the surface of the workpiece to remove the dust attachment on the workpiece. The disadvantage is that static electricity will be generated when wiping, and the original static electricity of the workpiece cannot be removed, and it will still be polluted by dust in the air. Moreover this method cost is higher, and the tiny fiber of wiping paper or cloth can be attached on the workpiece and cause repeated pollution.

Direct electrostatic dust removal: This method can remove the dust on the workpiece, but the removed dust swirls in the air, surrounding the entire workpiece, and the possibility of the workpiece being attached by dust again still exists.

Contents of the invention

The purpose of the invention of the utility model is to overcome the above-mentioned shortcomings of the prior art and provide a manual electrostatic precipitator that removes dust from the surface of the workpiece before spraying, and improves the surface paint adhesion and surface coating accuracy of the workpiece after dust removal.

The technical solution of the utility model is that: the workbench is provided with a working hole, the working hole is equipped with a working screen, and the dust suction funnel and the work hole are correspondingly installed at the lower end of the workbench; the dust suction funnel is connected with the exhaust fan through the exhaust pipe, There is an electrostatic gun on one side of the workbench, and the electrostatic gun is connected with the electrostatic generator.

The utility model is improved on the direct electrostatic dust removal method, adding a workbench to remove the dust swirling in the air, which can achieve a dust removal effect of 98.8%, directly improve the spraying quality of plastic workpieces by 2 to 3 times, and reduce the rework rate to about three thousandths. The utility model is applied in the painting industry to remove dust on the surface of the workpiece before spraying, so that the surface paint adhesion and surface coating accuracy of the workpiece after dust removal can be effectively improved.

Detailed ways

In Fig. 1, the workbench 2 is provided with a working hole, the working hole is equipped with a working screen, and the dust suction funnel 3 is installed at the lower end of the workbench 2 correspondingly to the work hole; Connection, there is an electrostatic gun 8 on one side of the workbench 2, and the electrostatic gun 8 is connected to the electrostatic generator 7. 1 is an operating room, 6 is a motor, and 9 is an air outlet.

Among Fig. 2, the top of workbench 2 is operating room 1, and dust suction funnel 3 is contained in the lower end of workbench 2. There is an electrostatic gun 8 on one side of the workbench 2, and the electrostatic gun 8 is connected with the electrostatic generator 7. 9 is an air outlet.

The utility model is applied to the pre-treatment of the coating workpiece to remove dust from the workpiece. The principle is to generate static electricity through the electrostatic generator 7, drive the static ions through the high-pressure air, and blow the static ions to the workpiece through the electrostatic gun 8, and the workpiece is placed on the workbench. 2, the dust removed enters the dust collection funnel 3, and is adsorbed by the high pressure of the exhaust fan 5, and the dust in the dust collection funnel 3 is drawn to the outside by the suction pipe 4.

The workpiece is placed on the workbench 2 to avoid static electricity pollution caused by improper dust blowing and hand contact caused by the operator holding the workpiece in general dust removal; the dust in the dust suction funnel 3 whirls in it and will not bounce back to the workpiece Effectively avoid secondary pollution.
