Technical Field

[0001] This utility model belongs to the field of paint mist interception application technology, specifically relating to a dry venturi paint mist collection box. Background Technology

[0002] Painting workshops or dry spray booths are the main places where "three wastes" (waste gas, wastewater, and solid waste) are generated during the entire production process. The overspray mist separation system of the spray booth is an important component of the spray booth, which determines the form and quantity of "three wastes" generated.

[0003] Currently, the main method for handling paint mist in vehicle painting production lines is the paper-box dry spray booth paint mist separation system. This system uses convenient paper-box filters, such as dry venturi paint mist collection boxes.

[0004] Currently, dry venturi paint mist collection boxes are typically designed for single-use applications. The adsorption of dry venturi paint mist collection boxes is mainly achieved through flexible columnar interception filter elements and mesh post-adsorption filter layers. If this part is changed to a replaceable structural design, it can be replaced, which can also meet the requirements of cost reduction and environmentally friendly production.

[0005] Therefore, based on the above problems, this utility model provides a dry venturi paint mist detection box. Utility Model Content

[0019] Example 1

[0020] like Figure 1 , Figure 2 and Figure 3 The dry venturi paint mist trap shown includes a square open cardboard frame 100, a mesh post-adsorption filter layer 109, and a flexible columnar interception filter element 113.

[0021] The square open cardboard frame 100 has a front groove 101 and a rear groove 105 respectively provided in the four corners of its two end faces.

[0022] The square open cardboard frame 100 has a front-reinforcing square cardboard frame 102 and a rear-reinforcing square cardboard frame 106 respectively on its two end faces.

[0023] The front reinforced square paper frame 102 and the rear reinforced square paper frame 106 are respectively provided with an air inlet slot 104 and an air outlet slot 108.

[0024] The four corner ends of the front reinforced square paper frame 102 and the rear reinforced square paper frame 106 are respectively provided with a front limiting protrusion 103 and a rear limiting protrusion 107 that match the front groove 101 and the rear groove 105.

[0025] The upper and lower inner walls of the square open cardboard frame 100 are evenly distributed with several upper limit grooves 117 and several lower limit grooves 110 for mutual use.

[0026] The lower limit groove 110 is provided with lower support protrusions 111.

[0027] A cylindrical hollow filter screen 112 is provided on one side of the lower support protrusion 111.

[0028] One end face of the cylindrical hollow filter screen 112 is provided with a trumpet-shaped internal threaded sleeve 114.

[0029] Cylindrical plugs 115 are provided inside the flared internal thread sleeve 114.

[0030] One side of the cylindrical plug 115 is provided with an upper support protrusion 116;

[0031] The flexible columnar interception filter element 113 is filled into the cylindrical hollow filter screen 112 through the horn-shaped internal thread sleeve 114, and the four corners of the mesh-like post-adsorption filter layer 109 are fitted onto the rear limiting protrusion 107.

[0032] The working principle is as follows:

[0033] Assembly: First, apply fixing adhesive evenly to the surface of the front limiting protrusion 103 and insert the front limiting protrusion 103 horizontally into the front groove 101; then, put the mesh-like rear adsorption filter layer 109 onto the rear limiting protrusion 107, apply fixing adhesive evenly to the surface of the rear limiting protrusion 107, and insert the rear limiting protrusion 107 horizontally into the rear groove 105; finally, fill the cylindrical hollow filter screen 112 with the flexible columnar intercepting filter element 113 through the horn-shaped internal thread sleeve 114, then rotate the cylindrical plug 115 through the upper support protrusion 116 to fix it to the horn-shaped internal thread sleeve 114, and then insert the upper support protrusion 116 and lower support protrusion 111 at both ends of the cylindrical hollow filter screen 112 into the upper limit groove 117 and lower limit groove 110 from the middle of the square open cardboard frame 100 to both sides.

[0034] When the flexible columnar filter element 113 needs to be replaced, simply hold the cylindrical hollow filter screen 112 and pull the upper support protrusion 116 and the lower support protrusion 111 horizontally away from the upper limit groove 117 and the lower limit groove 110. At the same time, rotate the cylindrical plug 115 through the upper support protrusion 116 to move the cylindrical plug 115 away from the flared internal threaded sleeve 114. Then, lift the flexible columnar filter element 113 away from the cylindrical hollow filter screen 112 through the flared internal threaded sleeve 114 to replace it with a new flexible columnar filter element 113.

[0035] In addition, preferably the lower support protrusion 111, the cylindrical hollow filter screen 112 and the flared internal thread sleeve 114 are made of elastic plastic in one piece; the cylindrical plug 115 and the upper support protrusion 116 are made of plastic in one piece.

[0036] With the above design structure, when the upper support protrusion 116 and the lower support protrusion 111 are pulled horizontally away from the upper limit groove 117 and the lower limit groove 110 by holding the cylindrical hollow filter 112, the cylindrical hollow filter 112 will bend and deform, which facilitates the quick disassembly or reassembly of the flexible columnar intercepting filter element 113.

[0037] In addition, preferably, the upper limit grooves 117 of the upper inner wall of the square open cardboard frame 100 are symmetrically arranged at both ends and irregularly arranged in the middle; the lower limit grooves 110 of the lower inner wall of the square open cardboard frame 100 are symmetrically arranged at both ends and irregularly arranged in the middle.

[0038] The above structural design can achieve efficient paint mist interception while maintaining normal ventilation volume.

[0039] In addition, preferably the front reinforcing square paper frame 102 and the rear reinforcing square paper frame 106 are the same size, and are respectively the same size as the two end faces of the square open paper frame 100. This design structure effectively enhances the strength of the square open paper frame 100 after assembly and extends its service life.

[0040] When it is necessary to replace the mesh rear adsorption filter layer 109, heat and melt the fixing adhesive on the rear groove 105 and the rear limiting protrusion 107 to pull the rear limiting protrusion 107 away from the rear groove 105, and then the new mesh rear adsorption filter layer 109 can be replaced.

[0041] This dry venturi paint mist collection box is suitable for use in filtration systems in painting workshops, dry spray booths, and other similar applications.
