Description

Technical Field

[0001] The invention relates to the technical field of dust removal, in particular to air purification equipment for a high-dust workshop. Background Art

[0002] In high-dust workshops, it is necessary to design a reasonable ventilation layout to ensure effective air circulation in the workshop, and install high-efficiency ventilation equipment, such as exhaust fans and exhaust fans, to remove dust from the workshop. In addition, for areas or processes with large amounts of dust, set up independent partition ventilation systems to increase ventilation frequency and dust collection capacity.

[0003] Place the air purifier in a suitable location in the workshop. The air purifier should be placed in a location with good indoor air circulation, avoid being close to walls, furniture or other obstacles to ensure that the air can smoothly enter and leave the purifier. Since pollutants such as dust in the air are heavy and will settle downward, the air purifier should be placed as low as possible, close to the source of dust or pollution, so as to more effectively capture and filter these pollutants. However, it is also necessary to ensure that there is no obstruction around the air purifier to avoid affecting its normal operation. In workshops with high requirements, it needs to be kept dry. Dust treatment generally adopts filtering. Filtration is a physical barrier to trap dust particles in the air on the filter medium, so as to achieve the purpose of purifying the air. The filter medium can be a filter bag, filter element or filter plate made of textiles, metal mesh, ceramics, plastics and other materials.

[0004] As the filtration proceeds, dust gradually accumulates on the filter equipment and will clog the filter holes. The filter equipment needs to be treated with external mechanical vibration or pulse blowing. However, the dust in the filter holes passes through the holes under the action of external mechanical equipment, which can easily expand or damage the holes. For filter equipment that needs to be cleaned frequently, it is easy to damage the filter equipment, resulting in poor filtration effect. Summary of the invention

[0005] The object of the present invention is to provide an air purification device for a high-dust workshop to solve the problems raised in the above background technology.

The mesh layer components are provided in two groups, and the two groups of mesh layer components are respectively located inside the two air intake layers, and the two mesh layer components are respectively located between the two inner support layers and are limited.

[0012] Furthermore, the control cylinder is cylindrical, and has two symmetrical curved surfaces and two symmetrical straight surfaces on its outer wall, the curved surfaces are used to squeeze the mesh component to tighten the mesh component, and the straight surfaces are used to relax the mesh component;

[0013] The arc surface of the control cylinder contacts the inner side of the inner support layer, and the arc surface is also provided with holes for air intake.

[0014] Furthermore, the mesh layer components include clamping bars, horizontal lines, limiting frames and vertical lines;

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0036] See also Figure 1-Figure 10 The present invention provides a technical solution: dust on the filter device gradually accumulates and will block the filter holes. The filter device needs to be treated by external mechanical vibration or pulse blowing. However, the dust in the filter holes passes through the holes under the action of external mechanical equipment, which is easy to expand or damage the holes. For the filter device that needs to be cleaned frequently, it is easy to damage the filter device, resulting in poor filtering effect. An air purification device for a high dust workshop is proposed, such as Figure 1 , Figure 2 and Figure 3 As shown, it comprises a cylinder 1, a cover plate 2 3 and a cover plate 1 2 are fixed to the upper and lower sides of the cylinder 1 respectively, a filter unit 7 is installed inside the cylinder 1, and the filter unit 7 comprises an inner support cylinder 71, a control cylinder 75 and a mesh component 76;

[0037] The inner support cylinder 71 is installed inside the cylinder body 1, and the control cylinder 75 and the mesh component 76 are installed inside the inner support cylinder 71. The mesh component 76 is used to filter dust, and the control cylinder 75 is used to control the tightness of the mesh component 76, which is controlled by the control cylinder 75. The outer wall of the control cylinder 75 has holes, which can move the filtered gas from the holes to the inside to complete the filtration.

[0038] like Figure 1 As shown, an air inlet pipe 5 and an air outlet pipe 6 are fixed to the outer sides of the cover plate 1 2 and the cover plate 2 3 respectively to ensure smooth air inlet and outlet;

[0039] The lower end of the cover plate 2 also supports a frame 4.

[0040] like Figure 3As shown, the inner support tube 71 is fixed to the lower end of the cover plate 2 3, and two air intake layers 72 are opened on the outer side of the inner support tube 71. The two air intake layers 72 are symmetrical, and air is taken in from the air intake layers 72;

[0041] like Figure 4 As shown, four inner support layers 73 are fixed on the inner wall of the inner support tube 71, and the four inner support layers 73 are respectively located on both sides of the two air intake layers 72. The inner side surface of the inner support layer 73 is arc-shaped, and its axis coincides with the axis of the inner support tube 71. Two groups of mesh layer components 76 are provided, and the two groups of mesh layer components 76 are respectively located inside the two air intake layers 72, and the two mesh layer components 76 are respectively located between the two inner support layers 73 and are limited. The four inner support layers 73 are in contact with the control tube 75, so that after the gas enters the air intake layer 72, it can only move inward through the holes of the control tube 75.

[0042] like Figure 5 As shown, in order to control whether the mesh component 76 can filter and how to facilitate cleaning after filtering, the control cylinder 75 is cylindrical, and the outer wall of the control cylinder 75 has two symmetrical curved surfaces 751 and two symmetrical flat surfaces 752. The curved surface 751 is used to squeeze the mesh component 76 to tighten the mesh component 76, and the flat surface 752 is used to relax the mesh component 76. The curved surface 751 and the flat surface 752 of the control cylinder 75 can control the tightness of the mesh component 76, which can achieve filtering and loose dust cleaning, so as to avoid the holes of the mesh component 76 being fixed, which may easily cause dust to pass through the holes during cleaning and cause the holes to expand, thereby affecting subsequent filtering;

[0043] The arcuate surface 751 of the control tube 75 contacts the inner side of the inner support layer 73, and the arcuate surface 751 also has holes for air intake. The holes are provided on the arcuate surface 751 because the arcuate surface 751 is squeezed with the mesh layer component 76, and the mesh layer component 76 forms a grid shape. During the filtering process, the gas needs to pass through the mesh layer component 76, so the gas also needs to pass through the holes on the arcuate surface 751.

[0044] like Figure 5 , Figure 6 and Figure 7 As shown, the mesh component 76 includes a clamping strip 761, a horizontal line 762, a limit frame 763 and a vertical line 765;

[0045] There are two clamping bars 761, and there are multiple horizontal lines 762 and multiple vertical lines 765. The multiple horizontal lines 762 are fixed between the two clamping bars 761, and the multiple horizontal lines 762 are loose. The multiple vertical lines 765 are fixed in the limiting frame 763. The multiple horizontal lines 762 and the multiple vertical lines 765 form a grid for filtering. The multiple horizontal lines 762 and the multiple vertical lines 765 are spliced ​​into sheets and have filtering holes to achieve the filtering effect. The holes can be invisible after being loosened, which is convenient for cleaning.

[0046] The clamping strip 761 and the limiting frame 763 need to be installed. The inner support layer 73 is penetrated from bottom to top with a clamping opening 74, and the clamping opening 74 cooperates with the clamping strip 761. The inner wall of the inner support tube 71 and the lower end of the cover plate 23 are provided with installation openings 766. The two installation openings 766 are used to cooperate with the limiting frame 763.

[0047] The longitudinal line 765 is located on the outside of the transverse line 762. Both the longitudinal line 765 and the transverse line 762 are dense lines. The transverse line 762 is located on the side in contact with the curved surface 751. Therefore, even if the transverse line 762 is affected by the rotation of the curved surface 751, it can remain evenly distributed. The longitudinal line 765 is not in direct contact with the curved surface 751, so it is less affected. In addition, the gas moves from the outside to the inside, which has a thrust on the longitudinal line 765 and the transverse line 762, so that the longitudinal line 765 and the transverse line 762 fit the curved surface 751, and further limit the longitudinal line 765 and the transverse line 762 to maintain stable filtration.

[0048] Multiple sets of limit clips 764 are fixed to the outer sides of the upper and lower branches of the limit frame 763. The multiple sets of limit clips 764 are used to limit the longitudinal lines 765 so that the longitudinal lines 765 are evenly distributed and the grid formed by the longitudinal lines 765 and the transverse lines 762 is kept uniform.

[0049] The working principle of the present invention is as follows: air is taken in from the air inlet pipe 5 and is discharged from the air outlet pipe 6. Dust in the air is filtered inside the cylinder 1. When the gas enters the cylinder 1, it passes through the air inlet layer 72 and the mesh layer component 76, enters the inner support cylinder 71, and then moves upwards out;

[0050] It should be noted that when the gas passes through the mesh component 76, the curved surface 751 of the control cylinder 75 is squeezed against the mesh component 76 and is in a state of supporting the mesh component 76. The horizontal lines 762 and the vertical lines 765 are both in a taut state, so that the mesh formed by the horizontal lines 762 and the vertical lines 765 is relatively tight to avoid deformation and achieve dust blocking. Secondly, the control cylinder 75 is rotated to make the flat surface 752 correspond to the mesh component 76, so that the horizontal lines 762 and the vertical lines 765 of the mesh component 76 are in a loose state. Then, the dust on the horizontal lines 762 and the vertical lines 765 are easily shaken off, which is convenient for separating the blocked dust. After that, when the horizontal lines 762 and the vertical lines 765 are tightened again, the expansion of the formed filter holes can be avoided. Based on this, the horizontal lines 762 and the vertical lines 765 that can be loosened and tightened can achieve a filtering effect, which is convenient for cleaning dust, and also avoids dust jamming, and can also avoid the formed filter holes from being deformed after long-term use.

[0051] Secondly, the formation and loosening of the filter net can be achieved by rotating the control cylinder 75, which is easy to control. In addition, by rotating the control cylinder 75, the arc surface 751 and the horizontal line 762 are squeezed to tighten the horizontal line 762. The horizontal line 762 is originally in a horizontal state and will not be offset during the rotation of the arc surface 751. The spacing between the horizontal lines 762 and 762 will not change, and the vertical line 765 is located on the outside of the horizontal line 762. The arc surface 751 has little effect on the vertical line 765. After the horizontal line 762 and the vertical line 765 are tightened, filter holes with relatively uniform spacing can be formed to ensure a good filtering effect.

[0052] In addition, the limiting clip 764 is provided to limit the longitudinal lines 765 so that the longitudinal lines 765 are relatively evenly distributed, thereby ensuring that the formed filter holes are relatively even and guaranteeing the filtering effect.
