Description

A filter equipment for car light spray booth

Technical Field

The utility model belongs to the technical field of the filter equipment technique and specifically relates to a filter equipment for car light spray booth is related to.

Background

After the automobile lamp is subjected to injection molding, a protective layer is sprayed on the surface of the automobile lamp in order to ensure the corrosion resistance and the weather resistance of the surface of the lampshade.

When the car lamp in the prior art is sprayed, the car lamp is placed on a cross rotating table of a spraying chamber, a workpiece is sprayed by a spraying mechanical arm, an exhaust system in the spraying chamber generally sucks external air into the spraying chamber through a circulating air conditioner in the spraying process, and then the air in the spraying chamber is exhausted outdoors through an exhaust fan. However, in the process of exhausting air by the exhaust fan, a large amount of paint enters the exhaust channel and is exhausted outdoors along with the air, and air is affected. Therefore, there is a need for a filtering device for filtering paint in an exhaust duct to reduce the discharge of paint into the air.

Drawings

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

Fig. 1 is a schematic view of the overall structure of the present invention;

fig. 2 is an enlarged view of a portion a in fig. 1.

In the figure, 1, a spray booth; 2. an air supply system; 3. an air exhaust channel; 4. organ type paint filter paper; 5. a paint felt filter; 6. a fixing frame; 7. and (5) sealing rings.

Detailed Description

The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.

Referring to fig. 1, a filtering device for a car lamp spray booth comprises a filter assembly fixed in the spray booth 1, an exhaust fan and an exhaust channel 3 are arranged outside the spray booth 1, one end of the exhaust channel 3 is communicated with an air inlet of the exhaust fan, and the other end is communicated with the filter assembly. When the exhaust fan works, paint in the spraying room 1 is exhausted from the exhaust channel 3 along with wind, and the filter assembly is used for filtering the paint in the wind, so that the paint is reduced to be exhausted into the air.

Specifically, as shown in fig. 1, the filter assembly includes two primary filters disposed perpendicular to each other, one of the primary filters is fixed to the bottom of the painting booth 1, and the other primary filter is fixed to the sidewall of the painting booth 1. Two first-level filters mutually perpendicular set up, can filter the paint of downward flow and the paint of lateral flow simultaneously for the filtration efficiency of paint in spray booth 1.

Specifically, as shown in fig. 1, the primary filter is preferably organ-type paint filter paper 4, the organ-type paint filter paper 4 can effectively absorb over-range overspray, and force the overspray to change direction for many times, so that particles heavier than air can be adhered to the paper wall surface and cannot be carried away with air flow.

As shown in fig. 2, in order to further improve the filtering effect of the paint, a fixing frame 6 is fixedly connected to the air outlet of the exhaust passage 3, and a secondary filter is fixedly connected to the inside of the fixing frame 6. The secondary filter can carry out secondary filter to the paint of 3 air outlets of air exhaust passage for the paint in the air of discharging has reduced air pollution still less.

Specifically, as shown in FIG. 2, the secondary filter is preferably a paint felt filter 5. The paint felt filter 5 is composed of high-strength continuous monofilament glass fibers, presents an enhanced structure, and is high in capture rate and good in paint isolation effect; the compression performance is good, the shape of the filter fiber can be kept unchanged, and the filter fiber is favorable for storing paint dust.

As shown in fig. 2, the paint in the exhaust duct 3 is easily discharged from the gap between the fixing frame 6 and the paint felt filter 5 during the outward discharge, so that a sealing ring 7 is provided at the contact portion of the fixing frame 6 and the paint felt filter 5, and the sealing ring 7 is located at the side of the paint felt filter far from the air outlet of the exhaust duct 3, that is, the side close to the painting booth 1. The sealing ring 7 makes it difficult for paint to escape from the gap between the fixing frame 6 and the paint mat filter, thereby reducing the escape of paint into the air.

The specific implementation process comprises the following steps:

air supply system 2 carries wind from top to bottom and side direction to spray booth 1 in, in the exhaust fan working process, organ formula paint filter paper 4 carries out prefilter to the wind of downward flow and side direction flow, filter most paint in the wind, wind continues to flow along exhaust passage 3, filter once more through paint felt filter 5 in the air outlet department of exhaust passage 3, then in discharging the air, reduce the paint in the wind through twice filtration, and then make the wind of discharging in the air cleaner, air pollution has been reduced.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
