Comprises a box body, an inlet arranged on the top surface of the bottom of the box body and an outlet arranged on the back surface of the box body, wherein a frame is arranged in the box body; a DPA filter is also arranged on the frame above the box body; an access door is arranged on the side surface of at least one side of the two sides of the box body below the DPA filter; the paint in the gas is filtered by arranging a DPA filter; the DPA filter is convenient to overhaul by arranging the access door; because the access door is arranged on two sides, the maintenance is more convenient.
Description
Technical Field
The utility model relates to a filter equipment field especially relates to a coating cloud filter equipment.
Background
Exhaust gas filters, a high efficiency and regenerable exhaust emission filter and filter system; at present, when paint in exhaust gas is filtered, a DPA filter is generally adopted in the filter for filtering, but as the service life of the DPA filter increases, paint particles on the DPA filter increase, which often causes damage to the DPA filter or greatly reduces the filtering effect of the DPA filter.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can detect and maintain a coating cloud filter equipment of DPA filter.
The technical scheme of the utility model as follows:
a paint mist filtering device comprises a box body, an inlet arranged on the top surface of the bottom of the box body, an outlet arranged on the back surface of the box body, and a frame arranged in the box body; a DPA filter is also arranged on the frame above the box body; and an access door is arranged on the side surface of at least one side of the two sides of the box body below the DPA filter.
The DPA filter is a dry paint mist filter.
And a pressure difference sensor is also arranged in the box body, one pressure guide port of the pressure difference sensor is positioned on the box body between the inlet and the DPA filter, and the other pressure guide port of the pressure difference sensor is positioned on the box body between the outlet and the DPA filter.
The top surface of the box body is arched upwards to form a bulge.
The cross section of the bulge is trapezoidal.
The outlet is located on the upper bottom surface of the protrusion.
The utility model has the advantages that: the paint in the gas is filtered by arranging a DPA filter; the DPA filter is convenient to overhaul by arranging the access door; the maintenance is more convenient because the maintenance door is arranged on the side surface of the box body; because the import sets up on the box top surface, practice thrift the space on the one hand, on the other hand such big particulate matter will directly hit the bottom plate along the air current on, realize supplementary filterable effect.
Drawings
The foregoing and other objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.
Wherein: fig. 1 is a schematic top view of the present invention;
in the attached drawing, 1 is a box body, 2 is an inlet, 3 is an outlet, 4 is a DPA filter, 5 is an access door, 6 is a cross rod, 8 is a bulge, 9 is a frame and 10 is a differential pressure sensor.
Detailed Description
Referring to fig. 1, the paint mist filtering device comprises a box body 1, an inlet 2 arranged on the top surface of the bottom of the box body, and an outlet 3 arranged on the back surface of the box body, wherein a frame is arranged in the box body; a DPA filter 4 (the DPA filter is made of a synthetic material, and the windward side of the filter adopts a 3D honeycomb laminated structure design to accord with the deep filtration principle, so that more paint mist can be captured, and more than 10 microns of small paint mist can be captured by 99.8%); and an access door 5 is arranged on the side surface of at least one side of the two sides of the box body below the DPA filter. The paint in the gas is filtered by arranging a DPA filter; the DPA filter is convenient to overhaul by arranging the access door; the maintenance is more convenient because the maintenance door is arranged on the side surface of the box body; because the import sets up on the box top surface, practice thrift the space on the one hand, on the other hand such big particulate matter will directly hit the bottom plate along the air current on, realize supplementary filterable effect.
And the side surfaces of two sides of the box body are respectively provided with an access door. And access doors are arranged on two sides of the box body, so that the selectivity is increased, and the access door on one side can be selected to be accessed for maintenance according to the actual situation on site.
The DPA filter is a dry paint mist filter. The dry paint mist filter has better filtering effect.
And a differential pressure sensor 10 is also arranged in the box body, one pressure guide port of the differential pressure sensor is positioned on the box body between the inlet and the DPA filter, and the other pressure guide port of the differential pressure sensor is positioned on the box body between the outlet and the DPA filter. The pressure values of the inlet and the outlet are respectively detected through two pressure guide ports of the pressure difference sensor, and when the pressure difference between the inlet and the outlet is larger, the DPA filter is indicated to filter enough paint and needs to be replaced or cleaned.
The top surface of the box body is arched upwards to form a bulge. The convex shape is adopted to have larger volume so as to facilitate the gas to flow out.
The side surfaces of the protrusions 8 are inclined surfaces. The inclined plane structure is adopted to facilitate the gas flow.
The outlet is located on the upper bottom surface of the protrusion.
The frame 9 is formed by a plurality of cross rods 6 and a plurality of vertical rods which are arranged in a staggered mode. The supporting effect is better by adopting the reticular framework.
The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the techniques of the present invention are substantially any simple modification and equivalent changes to the above embodiments, all falling within the protection scope of the present invention.
