Technical Field

The utility model relates to a flush coater coating field of collecting, concretely relates to environmental protection case for spraying operation.

Background

A spray coater is a special coating device adopting a spray coating technology, and is used for pressurizing sucked coating, conveying the coating into a spray gun of the spray coater through a high-pressure hose, atomizing the coating by the spray gun, and releasing the atomized coating onto the surface of an object to be coated so as to carry out spray coating.

However, since the paint is atomized and then sprayed on the surface of the object, it is inevitable that some of the atomized paint is emitted into the air, and if the paint is not treated, the environment is polluted. Therefore, the existing spraying operation is performed in a relatively closed space (i.e., a spraying chamber or a spraying box), so that the emission of the coating into the air is reduced, and the environmental pollution is reduced. However, in spite of this, the atomized coating material is still dispersed into the closed space during operation, so that there is still a problem that the coating material is wasted seriously.

Detailed Description

The present invention will be further explained with reference to the embodiments of the drawings.

As shown in fig. 1-3, the technical solution adopted by the utility model is: the utility model provides an environmental protection case for spraying operation, includes quick-witted case 1, fan 2, filter screen 3, filter equipment 5 and collecting hopper 4, fan 2 installs at the up end of quick-witted case 1 and the vertical portion of stretching into quick-witted case 1 in fan 2's suction opening, fan 2 includes motor, impeller and spiral case, the motor is used for driving the impeller rotation, the impeller is installed inside the spiral case.

Wherein, filter screen 3, filter equipment 5 and collecting hopper 4 are from last down installing in proper order inside quick-witted case 1, fan 2 is used for drawing the inside air of quick-witted case 1 towards the top, makes the air that has the coating of fog form in quick-witted case 1 successively through filter equipment 5 and filter screen 3.

Wherein, the air with vaporific coating can carry out the first filtration in filter equipment 5, makes vaporific coating filter become the liquid, filter equipment 5 includes stainless steel filter disc 501 and installation frame 502, and filter disc 501 quantity is set to four and overlap and install in installation frame 502 (see fig. 4-5), the cross section of filter disc 501 is the wavy line structure, and bottom fillet department is equipped with evenly distributed's filtration pore (see fig. 6), its filtration pore is not on same vertical line after four filter discs 501 installation to this lets the hole site stagger, thereby when making air from the bottom up get into inside, reaches the purpose that turns to many times, through making vaporific coating and filter disc 501 fully contact like this, with this guarantee that vaporific coating here all turns into liquid, then assemble the drippage to collection hopper 4 from filter equipment 5 again

Then, the air through filter equipment 5 can get into filter screen 3 in, carries out the secondary filter here, 3 quantity of filter screen are established to two, just its vertical cross-section is the "V" font structure of invering after two filter screens 3 installation, when fan 2 up extracted the air, can let the air go up in the inclined plane extraction of pasting filter screen 3 to make vaporific coating and the filter cotton layer in the filter screen 3 fully contact, carry out the secondary filter to the air with this, thereby guarantee that the coating in the air filters away completely, do not let the fan 2 above the coating pollution.

The end face of the collecting hopper 4 is inclined along the center, a leak is arranged at the center, a collecting box (not shown in the figure) is arranged on the lower end face in the case 1, and the collecting box is used for collecting liquid coating dropping from the collecting hopper 4.

The side wall of the case 1 is provided with an air inlet 101, the air inlet 101 is located between the filtering device 5 and the collecting hopper 4, and the air inlet 101 is used for providing convection for the work of the fan 2, so that the case 1 cannot influence the air extraction due to the space closure.

Wherein, the lower part of the case 1 is provided with a hinged door, and the collecting box can be replaced by a cross-over door.

The specific working principle is as follows: the utility model discloses be applied to reciprocating type flush coater on, the spraying operation district is located quick-witted incasement 1 inside, and the shower nozzle of flush coater is installed at quick-witted incasement and is located between aggregate bin 4 and the filter equipment 5, and quick-witted case 1 provides one for the spraying work of flush coater and compares inclosed space, and the vaporific coating that makes the flush coater during operation produce gives off quick-witted incasement 1 inside.

The fan 2 provides suction for the air flow of the inside of the case 1, so that the air with the mist-shaped coating sequentially passes through the filtering device 5 and the filter screen 3, the air can be filtered for the first time in the filtering device 5, the mist-shaped coating is filtered into liquid at the position and gradually gathered, then the air is dripped into the collecting hopper 4, and finally the coating can fall into the collecting box from a leakage opening along the inclined plane of the collecting hopper 4, so that the coating is collected, and the waste is reduced.

Wherein, can set up the baffle above the spray gun for shelter from liquid coating, influence the spraying operation when preventing that liquid coating from dripping.

And the air passing through the filtering device 5 can continue to pass through the filter screen 3, and is filtered for the second time at the position, so that the coating is prevented from entering the fan 2 and causing pollution to the fan 2.

The redundant paint in the spray chamber is collected and recycled through the actions, so that the waste of the paint is reduced, the production cost is saved, and meanwhile, the phenomenon that the fog-like paint is dispersed into the outside air to pollute the environment is reduced.

The above is only the preferred embodiment of the present invention, the present invention is not limited to the above embodiment, there may be local minor structural modification in the implementation process, if it is right that various modifications or variations of the present invention do not depart from the spirit and scope of the present invention, and belong to the claims and the equivalent technical scope of the present invention, then the present invention is also intended to include these modifications and variations.
