Description

Technical Field

[0001] The utility model belongs to the technical field of workshop dust removal, in particular to an air inlet box of a workshop dust removal system. Background Art

[0002] At present, a dust removal system is needed in steel structure processing and production workshops to introduce the air in the workshop into the outside world, so as to realize ventilation of the workshop and ensure the air quality in the workshop.

[0003] A dust removal system usually includes an air inlet box, a dust suction duct, a fan, a filter and other parts. The air inlet box in the prior art usually includes a box body and a plurality of air inlet holes arranged side by side on one side wall of the box body. One end of the dust suction duct is generally connected to the top wall of the box body or another side wall of the box body opposite to the side wall where the air inlet holes are located. Although the structure of this air inlet box is relatively simple, it is found during use that the air inlet holes close to the air inlet of the dust suction duct can play the role of air intake, but the air intake effect of the air inlet holes far away from the air inlet of the dust suction duct is relatively poor, thereby affecting the air intake effect of the air inlet box; moreover, after the air inlet box has been used for a period of time, dust will generally accumulate on the bottom wall of the box body, and to clean the dust on the bottom wall of the box body, the box body usually needs to be disassembled, which reduces the dust cleaning efficiency of the box body. Therefore, it is urgent to study an air inlet box for a workshop dust removal system in order to solve the above problems. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1:

[0023] See also Figure 1-2 and Figure 4-5As shown, the utility model is an air inlet box for a workshop dust removal system, comprising a bracket 1; a box body 2 vertically welded to the bracket 1; an air outlet 201 in a circular structure vertically provided on the top wall of the box body 2; a plurality of air inlet holes 202 in a rectangular strip structure arranged side by side on one side wall of the box body 2; a plurality of guide plates 3 are arranged obliquely from top to bottom inside the box body 2; and the upper edges of the plurality of guide plates 3 are bolted to one side wall of the box body 2. When in use, the air inlet of the dust collection duct is connected to the air outlet 201, and the dust collection duct is used to draw the box body 1 into a negative pressure state. Since the guide plates 3 guide the air inside the box body 2, the air inlet holes 202 away from the air outlet 201 can also draw air from the workshop into the box body 1, which not only effectively improves the overall utilization rate of the air inlet holes 202 on the box body 2, but also ensures the use effect of the air inlet box.

[0024] Example 2:

[0025] Based on Example 1 Figure 1-3 As shown, the bracket 1 includes a first support rod 101 horizontally welded to the other side wall of the box body 2 opposite to the side wall where the air inlet 202 is located; the two ends of the first support rod 101 are horizontally welded with a second support rod 102; the two second support rods 102 are horizontally welded to the opposite side walls of the box body 2, and the two second support rods 102 are vertically arranged with the first support rod 101; the lower surfaces of the two second support rods 102 are vertically welded side by side with a pair of third support rods 103; the lower ends of the two pairs of third support rods 103 extend to the bottom of the box body 2; the two pairs of third support rods 103 are all hollow tubes; the fourth support rods 104 are slidably inserted into the lower ends of the two pairs of third support rods 103; the opposite side walls of the two pairs of third support rods 103 are provided with a plurality of first through holes 105 side by side from top to bottom; one side surface of the two pairs of fourth support rods 104 are provided with a plurality of second through holes 106 corresponding to the first through holes 105 side by side from top to bottom; a connecting column 107 is slidably inserted into any first through hole 105 on each third support rod 103, and the connecting column 107 is slidably inserted into the corresponding second through hole 106. When in use, the lower ends of the two pairs of fourth support rods 104 are bolted to the workshop floor, and the fourth support rods 104 are used to slide on the third support rods 103 to adjust the installation height of the box body 2. The connection between the fourth support rods 104 and the third support rods 103 is then achieved by passing the connecting column 107 through the first through hole 105 and the second through hole 106. This not only effectively improves the installation stability of the box body 2, but also makes it convenient for workshop workers to use the air intake box.

[0026] Example 3:

[0027] Based on Example 2, Figure 4-6As shown, the bottom wall of the box body 2 is tilted; a rectangular drain outlet 203 is provided at the lower portion of the other side wall of the box body 2 opposite to the side wall where the air inlet 202 is located; the lower edge of the bottom wall of the box body 2 extends to the drain outlet 203; a baffle 204 is connected to the drain outlet 203; the lower edge of the baffle 204 is integrally formed with a limited flange 205; when the baffle 204 is vertically arranged at the drain outlet 203, the limited flange 205 is arranged parallel to the bottom wall of the box body 2, and the upper surface of the limited flange 205 is in contact with the lower surface of the bottom wall of the box body 2; the upper edge of the baffle 204 The edges are rotatably connected side by side with multiple vertically arranged supporting plates 206; multiple supporting plates 206 are vertically provided with through grooves 207 on the side away from the box body 2; multiple positioning columns 208 are slidably inserted into the multiple through grooves 207, and the positioning columns 208 can slide up and down in the through grooves 207; one end of the multiple positioning columns 208 is vertically welded to the other side wall of the box body 2 opposite to the side wall where the air inlet 202 is located; the other end parts of the multiple positioning columns 208 are threadedly fitted with limiting sleeves 209; multiple limiting sleeves 209 are arranged on the side of the supporting plate 206 away from the box body 2. When in use, the baffle 204 is vertically set at the discharge port 203, and the limiting flange 205 is set parallel to the bottom wall of the box body 2, and then the supporting piece 206 is pulled upward to make the upper surface of the limiting flange 205 fit with the lower surface of the bottom wall of the box body 2, and then the limiting sleeve 209 is rotated to clamp the supporting piece 206 between the limiting sleeve 209 and the box body 1, so as to realize the positioning of the baffle 204, thereby also realizing the blocking of the discharge port 203, which can ensure The dust collection effect of the box body 1 is improved; and when the air inlet box needs to be cleaned after a period of use, the limiting sleeve 209 is loosened to prompt the positioning column 208 to slide in the through groove 207, so that the supporting piece 206 and the baffle 204 move downward, so that the limiting flange 205 is away from the bottom wall of the box body 2, and then the baffle 204 is rotated to open the discharge port 203, and then the bottom wall of the box body 1 is cleaned, which effectively improves the cleaning efficiency of the box body 1.
