Description

Technical Field

[0001] The invention belongs to the field of environmentally friendly spray painting, and in particular relates to a method for installing a double-layer filter cotton frame on the top of a spray painting room. Background Art

[0002] The paint spray room is the main equipment in the painting workshop. Its function is to prevent the paint mist and solvent evaporation from escaping through the indoor airflow, limit the paint mist generated during the spraying process to a certain range, and form clean air after filtering and discharge to the outside, thereby reducing the emission of pollutants. Therefore, the performance of the paint spray room directly determines the environmental friendliness of the workshop painting.

[0003] During the spraying construction, the paint atomized by high-pressure air forms a large amount of paint mist. The paint mist is composed of paint particles and solvents. The paint mist has a small specific gravity and floats in the air. It settles on the surface of the workpiece and affects the quality of the workpiece. Operators inhaling paint mist is harmful to their health. Therefore, it is necessary to install a filter cotton frame on the top of the paint spray room. An exhaust system is set on the top of the paint spray room. The air containing paint mist in the paint spray room passes through the exhaust system and passes through the filter cotton frame on the top and is filtered and discharged to the outside, thereby improving the environmental protection level. However, the single-layer filter cotton has a poor filtering effect on the paint mist. If a double-layer filter cotton frame is set, the filtering effect is better. However, the double-layer filter cotton frame is usually installed on the top of the paint spray room by welding. When replacing the upper filter cotton frame, it is necessary to cut and remove the upper filter cotton frame and then replace the filter cotton. Moreover, after multiple replacements, it will affect the inner wall structure of the paint spray room, thereby shortening the service life of the paint spray room. Summary of the invention

[0004] The purpose of the present invention is to overcome the above shortcomings and provide a method for installing a double-layer filter cotton frame on the top of a paint spraying room. The filter cotton grille is installed in a positive and negative flipping manner, and the filter cotton grille is blocked by a blocking rod to ensure the convenience of installation and disassembly and the structural strength of the inner wall of the paint spraying room.

[0005] The purpose of the present invention is achieved through the following technical solution: a method for installing a double-layer filter cotton frame on the top of a paint spraying room, the specific steps include:

[0006] S1. Weld and fix a plurality of transverse rods and vertical rods according to the size of the filter cotton frame on a horizontal turning machine. The plurality of transverse rods and the vertical rods are perpendicular to each other to form an inner keel frame of the filter cotton. The inner keel frame of the filter cotton has a plurality of evenly distributed rectangular holes.

[0007] S2. Welding fixed limit strips along the upper edge of the inner keel frame of the filter cotton, wherein the fixed limit strips are distributed on the outer edge of the rectangular hole and the openings of the relatively arranged fixed limit strips are arranged facing each other;

[0008] S3, making a grille frame according to the distance between two fixed limit bars arranged opposite to each other around the rectangular hole;

[0009] S4, cutting the filter cotton according to the size of the grille frame, inserting the filter cotton into the grille frame, fixing cross-arranged reinforcing bars on both side end faces of the grille frame, and sealing the filter cotton in the grille frame with the reinforcing bars to form a single filter cotton grille;

[0010] S5, sequentially installing a plurality of filter cotton grids in a plurality of fixed limit clamping strips that surround to form a rectangular structure, and providing an inclined material blocking rod at the end corner of the filter cotton grid, and connecting and fixing the two ends of the material blocking rod to the corresponding fixed limit clamping strips, so that the filter cotton grid is fixedly connected to the inner keel frame of the filter cotton;

[0011] S6, the horizontal turning machine turns over, so that the filter cotton grid fixed to the upper edge of the filter cotton inner keel frame turns downward and contacts with the horizontal turning machine, so that the original lower side end face of the filter cotton inner keel frame is placed on the upper side;

[0012] S7, looping steps S2-S5, installing a filter cotton grid and a material blocking rod on the upper side of the filter cotton inner keel frame to form a double-layer filter cotton frame;

[0013] S8. Weld a plurality of hanging ears on the top of the double-layer filter cotton frame, and weld hooks corresponding to the plurality of hanging ears in sequence on the top of the spray booth;

[0014] S9. Connect the buffer rubbers at the four edges of the double-layer filter cotton frame by glue, and hoist the double-layer filter cotton frame as a whole, so that the lifting ears of the double-layer filter cotton frame are connected and corresponded with the hooks in sequence;

[0015] S10. Filter cotton is embedded in the gap between the double-layer filter cotton frame and the side of the paint spraying room, and multiple support plates are welded at the bottom of the paint spraying room. Multiple support frames are evenly distributed around the lower side of the double-layer filter cotton frame.

[0016] A further improvement of the present invention is that the height of the filter cotton frame is 0.2-0.4m.

[0017] A further improvement of the present invention is that both the inner transverse rod and the vertical rod are provided with ventilation holes.

[0018] A further improvement of the present invention is that: step S9 lifts the double-layer filter cotton frame, installs the lifting equipment on the top of the paint spraying room, and after the lifting is completed, evacuates the lifting equipment and installs the top of the paint spraying room into a closed state.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] The present invention adopts a positive and negative flipping method to install the filter cotton grille, and blocks the filter cotton grille through a material blocking rod to ensure the convenience of installation and disassembly; secondly, a method of integrally hoisting the double-layer filter cotton frame is adopted, and the double-layer filter cotton frame is effectively supported through the mutual cooperation of the lifting ear and the hook, and then a plurality of support plates are welded at the bottom of the spray paint room, and a plurality of support frames are evenly distributed on the lower peripheral position of the double-layer filter cotton frame. The setting of the support frame reduces the gravity load of the hook on the double-layer filter cotton frame, and the cooperation between the hook and the lifting ear also reduces the bearing capacity of the support frame on the double-layer filter cotton frame, thereby ensuring the connection strength of the overall structure and the structural strength of the spray paint room.
