[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0035] Combine the following Figures 1 to 8 The invention describes an air film structure closed material shed with air purification function.

[0036] like Figures 1 to 3As shown, in one embodiment, an air film structure closed material shed with air purification function includes an air film cover 20, an air supply device 30 for providing an internal and external air pressure difference for the air film cover 20, and a material pile 40 located in the air film cover 20, and also includes a purification component 10, the purification component 10 includes a purification box 100, a positioning box 200, an elastic cover 300, a magnetic suction frame 500, a plug-in shell 600 and a filter 700; a plurality of installation cavities 110 are arranged inside the purification box 100; the positioning box 200 is fixed between two adjacent installation cavities 110, And they are respectively connected to adjacent installation cavities 110; the outer circle of the elastic cover 300 is connected to the inner wall of the purification box 100, and the inner circle is connected to the end of the positioning box 200; the magnetic frame 500 is sleeved on the end of the positioning box 200 and fits with the elastic cover 300; the plug-in shell 600 is plugged into the installation cavity 110, and the magnetic frame 500 can be adsorbed on the surface of the plug-in shell 600 or when the plug-in shell 600 withdraws from the installation cavity 110, it is adsorbed on an adjacent magnetic frame 500; the filter element 700 can be detachably installed in the plug-in shell 600 for filtering dust impurities.

[0037] Furthermore, the purification box 100 can be placed in the shed or fixed on the retaining wall of the material shed to form an integral body with the wall.

[0038] Furthermore, the magnetic frame 500 will deform when subjected to external force.

[0039] Specifically, when in use, the air supply device 30 is started to inflate the interior of the air film cover 20, so that the air film cover 20 is lifted up by the airflow and maintains the arched state when there is a certain air pressure difference between the internal and external environments, and then the air circulation device is started. It should be noted here that the air circulation device is arranged on one side of the purification box 100, and is used to make the air inside the air film cover 20 flow in a certain direction and pass through the purification box 100 during the flow. When the purification box 100 is in use, the plug-in shell 600 will remain plugged into the installation cavity 110, and under the influence of the adsorption of the magnetic frame 500, the elastic cover 300 will be driven to fit the surface of the plug-in shell 600. At this time, the airflow entering the purification box 100 will pass through multiple plug-in shells 600 and be filtered by the detachable filter 700 inside the plug-in shell 600. Dust and impurities, when a filter 700 inside the purification box 100 filters too much dust and impurities and becomes clogged, it is only necessary to pull out the plug-in shell 600 where the filter 700 is located from the installation cavity 110. When pulling out, the magnetic frame 500 adsorbed on the plug-in shell 600 will move with the withdrawal of the plug-in shell 600, and adsorb on another magnetic frame 500 located in the same installation cavity 110 when the plug-in interface is completely pulled out. Figure 8 As shown, the purification path in the purification box 100 continues to be connected, and the purification box 100 does not need to be closed during the process.

[0040] The above-mentioned air film structure closed material shed with air purification function starts the external air circulation device when in use. The air circulation device is arranged on one side of the purification box 100, and is used to make the air inside the air film cover 20 flow in a certain direction and pass through the purification box 100 during the flow. When the purification box 100 is in use, the plug-in shell 600 will remain plugged into the installation cavity 110, and under the influence of the adsorption of the magnetic frame 500, the elastic cover 300 will be driven to fit the surface of the plug-in shell 600. At this time, the airflow entering the purification box 100 will pass through multiple plug-in shells 600 and be filtered by the detachable filter element 700 inside the plug-in shell 600. Dust impurities, when a certain filter element 700 inside the purification box 100 filters When there are too many dust impurities and blockage occurs, it is only necessary to pull out the plug-in shell 600 where the filter element 700 is located from the installation cavity 110. When pulling it out, the magnetic frame 500 adsorbed on the plug-in shell 600 will move with the withdrawal of the plug-in shell 600, and when the plug interface is completely pulled out, it will be adsorbed on another magnetic frame 500 located in the same installation cavity 110, so that the purification path in the purification box 100 continues to be conductive, and there is no need to close the purification box 100 during the process. The material shed equipped with the purification box 100 can not only purify the air in most of the space in the air film cover 20, but also there is no need to suspend the purification work when replacing the internal filter element 700. It is easy to use and has a long working time.

[0041] like Figure 4 As shown, in one embodiment, a plurality of partitions 130 are linearly arranged inside the purification box 100, and an installation cavity 110 is formed between two adjacent partitions 130. A mounting port 120 is provided at the bottom end of the installation cavity 110, and a mounting groove 131 is provided in the middle of the partition 130. First mounting holes 132 are coaxially provided on both sides of the installation groove 131, and the first mounting hole 132 passes through the outer wall of the purification box 100.

[0042] like Figure 5 As shown, in one embodiment, the positioning box 200 includes a first shell 210 and two telescopic cylinders 220. The upper surface and the lower surface of the first shell 210 are both arranged in an arc-shaped structure, and the central axes of the two coincide. A second mounting hole 211 is opened in the middle of the first shell 210. The two telescopic cylinders 220 are respectively located in two adjacent mounting cavities 110, and one end of the two telescopic cylinders 220 is respectively connected to the two sides of the first shell 210.

[0043] Specifically, the first shell 210 is located in the mounting groove 131 and is fixedly connected to the mounting groove 131. The upper surface and the lower surface of the first shell 210 are arc surfaces with coinciding centers. Both side surfaces of the first shell 210 are planes and are parallel to the side surfaces of the purification box 100. Two openings are formed between the upper and lower surfaces and the two side surfaces of the first shell 210. The two openings are respectively located at the front and rear ends of the first shell 210, that is, facing the direction of the air inlet and outlet of the purification box 100.

[0044] In one embodiment, a flexible rod is connected in series to the edge of the telescopic cylinder 220 , and the flexible rod is used to guide the telescopic cylinder 220 , and the flexible rod always maintains a straight line when not affected by external forces.

[0045] Specifically, the telescopic cylinder 220 may be a bellows or similar structure, and in order to ensure that the telescopic cylinder 220 can move along the front and rear ends of the purification box 100 instead of swinging around irregularly, in this embodiment, a limit head is provided on the edge of the telescopic cylinder 220, and a flexible rod is inserted into the limit head to ensure that the telescopic cylinder 220 can move along the front and rear ends of the purification box 100. It should be noted that the limit head can be any component or structure that can limit the flexible rod, such as a clamp ring, a fastener, etc., and the flexible rod can be a steel wire with elasticity and toughness.

[0046] In one embodiment, the elastic cover 300 includes a first fixed frame 310 and an elastic net 320 , the outer wall of the first fixed frame 310 is connected to the inner wall of the purification box 100 , the outer circle of the elastic net 320 is connected to the first fixed frame 310 , and the inner circle of the elastic net 320 is connected to the other end of the telescopic cylinder 220 .

[0047] Specifically, the telescopic cylinder 220 and the elastic net 320 can be regarded as a whole, with the telescopic cylinder 220 as the main body of the two. The telescopic cylinder 220 can move along the front and rear end directions of the purification box 100, and the setting of the elastic net 320 can block the edge space of the telescopic cylinder 220 to prevent dust impurities in the air from entering the place outside the filter element 700, thereby ensuring the cleanliness of the purification box 100.

[0048] In one embodiment, a slope 510 is provided at the connection between a side of the magnetic frame 500 that is in contact with the elastic net 320 and a side that is away from the telescopic tube 220 .

[0049] Specifically, when the magnetic suction frame 500 is attracted to the plug-in shell 600, since the plug-in position of the plug-in shell 600 is fixed, that is, located in the middle of the installation cavity 110, the magnetic suction frame 500 will be attracted and attached to the plug-in shell 600. In the process of being attracted and moving, since the magnetic suction frame 500 is sleeved on the telescopic cylinder 220, the telescopic cylinder 220 will be driven to move toward the plug-in shell 600, and since the inner circle of the elastic net 320 is connected to the port of the telescopic cylinder 220, when the end of the telescopic cylinder 220 moves, the elastic net 320 will also be driven and move closer to the plug-in shell 600, further limiting the space in the installation cavity 110 and preventing particulate matter, dust and impurities in the air from entering or entering in large quantities. Among them, the setting of the inclined surface 510 can provide deformation space for the elastic net 320.

[0050] In one embodiment, the magnetic frame 500 will deform when subjected to external force.

[0051] Specifically, when the plug-in shell 600 is pulled out from the installation cavity 110, the magnetic frame 500 will move on the plug-in shell 600 as the plug-in shell 600 is pulled out, and the specific trajectory is gradually upward until the plug-in shell 600 is completely separated from the installation cavity 110. At this time, the two adjacent magnetic frames 500 will be adsorbed together. If the magnetic frame 500 is made of hard material, it is inevitable that one end of the two magnetic frames 500 is adsorbed and the other end has a large gap during this process, so that the air with particulate matter, dust and impurities flows out from the gap between the two magnetic frames 500. If the magnetic frame 500 is set to be deformable, it can effectively avoid the large gap between the two magnetic frames 500 during the mutual adsorption process.

[0052] like Figure 7 As shown, in one embodiment, the plug-in shell 600 includes a second shell 610 and a snap-in plate 620. The second shell 610 is hollow inside and has an arc-shaped structure on the top. The portion of the second shell 610 facing the telescopic cylinder 220 is set as a mesh structure. The snap-in plate 620 is fixed on both sides of the bottom end of the second shell 610. The snap-in plate 620 is bent and set to be snap-fitted and fixed on the purification box 100.

[0053] In one embodiment, the filter element 700 includes a filter plate 710, an arc plate 720 and a positioning plate 730. The arc plate 720 is fitted on the top of the second shell 610, and the positioning plate 730 is detachably installed on the bottom of the second shell 610. The filter plate 710 is located between the positioning plate 730 and the arc plate 720, and is connected to the positioning plate 730 and the arc plate 720 respectively.

[0054] Specifically, the arc plate 720 is used to scrape off the particulate matter, dust and impurities adsorbed on the inner wall of the second housing 610 when the positioning plate 730 is pulled out, so as to avoid the filtered particulate matter, dust and impurities remaining inside the second housing 610 .

[0055] like Figure 6 As shown, in one embodiment, it also includes a rotating fan 400, which includes a rotating rod 410, a plurality of second fixed frames 420 and a plurality of wind shields 430. The end of the rotating rod 410 is inserted into the first mounting hole 132 and the second mounting hole 211. The plurality of second fixed frames 420 are distributed in a circular array around the rotating rod 410 and are fixed on the rotating rod 410. The plurality of wind shields 430 are respectively mounted on the plurality of second fixed frames 420, and a recessed space is formed between the surface of the wind shield 430 and the second fixed frames 420.

[0056] In the above-mentioned air film structure closed material shed with air purification function, when the purification box 100 is in use, the plug-in shell 600 will remain plugged in the installation cavity 110, and under the influence of the adsorption of the magnetic frame 500, the elastic cover 300 will be driven to fit the surface of the plug-in shell 600. At this time, the airflow entering the purification box 100 will pass through multiple plug-in shells 600 and be filtered by the detachable filter element 700 inside the plug-in shell 600. Dust impurities, when a filter element 700 inside the purification box 100 filters too much dust impurities and becomes blocked, it is only necessary to remove the plug-in shell 600 where the filter element 700 is located from When the plug-in shell 600 is pulled out from the installation cavity 110, the magnetic frame 500 adsorbed on the plug-in shell 600 will move with the withdrawal of the plug-in shell 600, and will be adsorbed on another magnetic frame 500 located in the same installation cavity 110 when the plug-in interface is completely pulled out, so that the purification path in the purification box 100 continues to be conducted, and there is no need to close the purification box 100 during the process. The material shed equipped with the purification box 100 can not only purify the air in most of the space in the air film cover 20, but also there is no need to suspend the purification work when replacing the internal filter element 700. It is easy to use and has a long working time.

[0057] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
