Description

Technical Field

[0001] This utility model relates to the field of bottom ventilation technology, specifically a bottom ventilation filter and adjustment structure. Background Technology

[0002] Nowadays, all industries are paying increasing attention to product quality. When processing parts in bus and car manufacturing equipment, such as grinding and touch-up painting, a ventilation system is needed to prevent dust from scattering and to blow the dust vertically downwards. Since grinding or touch-up painting itself generates dust and impurities in the air, a filter must be added to the air intake and exhaust vents to remove dust and other substances.

[0003] Currently, conventional bottom filter plates require an external galvanized mesh frame to cover the entire filter plate. When replacing them, the cover plate needs to be opened. The cover plate also needs to be made by first making an outer frame with folded edge plates and then welding perforated parts to the frame, which is costly. Replacement also requires consideration of whether the space can be used to open the cover plate, which also occupies a lot of space.

[0004] Based on this, a bottom exhaust filtration and regulation structure is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a bottom exhaust filter adjustment structure, which utilizes more space, reduces manufacturing costs, and makes it easier for personnel to replace the plate filter, thus solving the problems of high manufacturing costs and large space occupation of existing technologies.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bottom exhaust filter adjustment structure, including a wall panel, an adjustment plate is provided on the outer side of the wall panel, a positioning screw is threaded on the outer wall of the wall panel, the positioning screw passes through the inner side of the adjustment plate, a filter is provided between the adjustment plate and the wall panel, and a positioning component is provided on the outer side of the filter;

[0007] The positioning component includes a slotted plate, which is fixedly welded to the outer wall of the wall panel. A fixing sleeve is fixedly connected to the inner side of the slotted plate, and a tightening screw is threadedly connected to the inner side of the fixing sleeve. A butterfly handle is fixedly connected to one end of the tightening screw.

[0008] Furthermore, an exhaust vent is provided on the outer wall of the wall panel, and the adjusting plate corresponds to the exhaust vent.

[0009] Furthermore, the adjusting plate has a slot near the positioning screw, and there are four positioning screws and four slots.

[0010] Furthermore, the number of positioning components is set to four groups, with the four groups of positioning components located at the bottom and left and right sides of the filter, respectively, and the adjustment plate located between the four groups of positioning components.

[0011] Furthermore, the card slot folding plate is formed by folding the edge of a sheet material, and the shape of the card slot folding plate is Z-shaped.

[0012] Furthermore, a number of mounting holes are provided on the outer wall of the wall panel.

[0013] Compared with the prior art, the present invention provides a bottom exhaust filtration and adjustment structure, which has the following beneficial effects:

[0014] This bottom exhaust filter adjustment structure connects the wall panel and the adjustment plate with positioning screws, leaving a gap between them to accommodate the filter. A positioning component is installed on the wall panel, and the filter is inserted directly from above, positioning it between the wall panel and the adjustment plate. The positioning component then presses the filter firmly in place. If local exhaust ventilation requires reducing the exhaust volume, the airflow area can be adjusted by stretching the adjustment plate left and right, thus achieving exhaust adjustment. This structure allows for greater space utilization compared to traditional bottom filter structures, reduces manufacturing costs, and makes it easier for personnel to replace the plate filter. It is highly practical and solves the problems of high manufacturing costs and large space requirements associated with existing technologies. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1:

[0022] Please see Figures 1 to 4 The bottom exhaust filter adjustment structure in this embodiment includes a wall panel 1, an adjustment plate 2 is provided on the outer side of the wall panel 1, a positioning screw 4 is threaded on the outer wall of the wall panel 1, the positioning screw 4 passes through the inner side of the adjustment plate 2, and a filter 3 is provided between the adjustment plate 2 and the wall panel 1.

[0023] Among them, the outer wall of the wall panel 1 is provided with an exhaust hole, and the regulating plate 2 is corresponding to the exhaust hole.

[0024] In this embodiment, a positioning component 6 is provided on the outer side of the filter 3. The positioning component 6 includes a slotted folding plate 601. The slotted folding plate 601 is formed by folding the edge of a plate. The slotted folding plate 601 is Z-shaped. The slotted folding plate 601 is fixedly welded to the outer wall of the wall panel 1. A fixing screw sleeve 602 is fixedly connected to the inner side of the slotted folding plate 601. A tightening screw 603 is threadedly connected to the inner side of the fixing screw sleeve 602. A butterfly handle 604 is fixedly connected to one end of the tightening screw 603.

[0025] The number of positioning components 6 is set to four sets, with the four sets of positioning components 6 located at the bottom and left and right sides of the filter 3 respectively, and the adjustment plate 2 located between the four sets of positioning components 6.

[0026] It is understandable that the four sets of positioning components 6 can limit the upper and lower positions of the adjustment plate 2. Please refer to [link / reference needed]. Figure 1 The tightening screws 603 in the two sets of positioning components 6 below can press the adjusting plate 2 against the wall, and the tightening screws 603 in the two sets of positioning components 6 above can press the filter 3 against the wall.

[0027] It should be noted that the adjusting plate 2 has a slot 5 near the positioning screw 4. There are four positioning screws 4 and four slots 5. The slots 5 facilitate the left and right adjustment of the position of the adjusting plate 2. By rotating the tightening screws 603 in the two sets of positioning components 6 below, the adjusting plate 2 can be moved away from the adjusting plate 2, making it easier to slide the adjusting plate 2. After adjusting to the appropriate position, the butterfly handle 604 can be rotated to adjust the tightening screws 603 to fix the adjusting plate 2 again.

[0028] Example 2:

[0029] Please see Figure 1 Based on Embodiment 1, a plurality of mounting holes 7 are provided on the outer wall of the wall panel 1, which can be used for mounting the wall panel 1.

[0030] The working principle of the above embodiments is as follows:

[0031] In use, the wall panel 1 and the adjusting plate 2 are connected by positioning screws 4, with a gap reserved between them to accommodate the filter 3. The positioning component 6 is installed on the wall panel 1, and the filter 3 is inserted directly from the top, positioning it between the wall panel 1 and the adjusting plate 2. The positioning component 6 is then used to press and fix the filter 3. If the exhaust volume needs to be reduced for local exhaust ventilation, the air passage area can be adjusted by stretching the adjusting plate 2 left and right, thus realizing exhaust ventilation adjustment, reducing manufacturing costs, and making replacement and use more convenient.
