[0029] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0030] See also Figures 1 to 3 The utility model provides a dust removal device with an air blocking component:
[0031] like Figure 1 and Figure 2 As shown, a dust removal device with an air blocking component includes a first sealed box 1, a second sealed box 3, a filter element 5, an air blowing pipe and an air blocking component.
[0032] The first sealed box 1 has a first cavity. A first air outlet 2 is provided on the first sealed box 1 . The first air outlet 2 is connected to the first cavity. The gas in the first cavity can be extracted to the outside of the first sealed box 1 through the first air outlet 2 .
[0033] The second sealed box 3 has a second cavity, and a first air inlet 4 is provided on the second sealed box 3. The first air inlet 4 is connected to the second cavity. The dust-containing gas can be sent into the second cavity through the first air inlet 4, and then the dust-containing gas is dust-removed and filtered.
[0034] The filter element 5 is used for dust removal and filtration of dust-containing gas. The filter element 5 has a third cavity and an opening connected to the third cavity. When the dust-containing gas enters the third cavity through the outer wall of the filter element 5, the dust will be blocked by the outer wall of the filter element 5, and only the gas can enter the third cavity, thereby achieving dust filtration. At least a part of the filter element 5 is located in the second cavity, and the opening of the filter element 5 is connected to the first cavity. Since the dust removal of the gas is achieved in the second cavity, at least a part of the filter element 5 is set in the second cavity, that is, part or all of the filter element 5 is located in the second cavity, and the treated gas enters the first cavity through the opening of the filter element 5. The number of filter elements 5 is one or more. The more filter elements 5 there are, the better the dust removal effect is. The number of filter elements 5 is determined according to actual needs.
[0035] The air blowing pipe has a second air inlet and a second air outlet. The second air inlet of the air blowing pipe is located outside the first sealed box 1 and the second sealed box 3 so that air can be blown into the air blowing pipe from the outside. The second air outlet of the air blowing pipe is located in the third cavity. The gas blown into the air blowing pipe from the outside enters the third cavity through the air blowing pipe.
[0036] The air blocking component is used to close or open the opening of the filter element 5. Specifically, the air blocking component opens the opening of the filter element 5 when the dust removal equipment is removing dust, and closes the opening of the filter element 5 when the dust removal equipment is removing dust attached to the filter element 5.
[0037] When using the dust removal equipment for dust removal, the air blocking component opens the opening of the filter element 5, and exhausts air through the first air outlet 2 of the first sealing box 1. The air pressure in the first cavity is reduced, and a pressure difference is formed between the inside and outside of the filter element 5. The gas enters the third cavity through the filter element 5, and then the gas enters the first cavity from the third cavity. The dust in the gas is blocked on the outer surface of the filter element 5, thereby realizing the function of gas dust removal. When it is necessary to remove the dust on the surface of the filter element 5, the air blocking component closes the opening of the filter element 5 to prevent the gas in the third cavity from entering the first cavity, and blows air inward from the second air inlet of the blowing pipe. The gas enters the third cavity through the blowing pipe, and the air pressure in the third cavity increases, so that the gas flows from the third cavity to the outside of the filter element 5, thereby flushing away the dust attached to the outer surface of the filter element 5, and realizing the removal of dust attached to the filter element 5.
[0038] In some embodiments, the dust removal device further includes a receiving tray 8, which is located in the second cavity and below the filter element 5. When removing dust from the surface of the filter element 5, the gas flows from the third cavity to the outside of the filter element 5, flushing away the dust attached to the outer surface of the filter element 5, and the dust falls downward into the receiving tray 8 under the action of gravity.
[0039] The number of the receiving trays 8 is one or more. When the number of the receiving trays 8 is multiple, each filter element 5 may correspond to one receiving tray 8, or multiple filter elements 5 may correspond to one receiving tray 8.
[0040] In some embodiments, the vertical projection of the filter element 5 on the plane where the receiving tray 8 is located is located in the receiving tray 8, that is, the collecting area of the receiving tray 8 is ensured to be larger than the vertical projection of the filter element 5 on the plane where the receiving tray 8 is located, and the vertical projection is located in the receiving tray 8, thereby ensuring that the dust falling from the filter element 5 can be collected by the receiving tray 8. Generally, the larger the area of the receiving tray 8, the better the dust collection effect.
[0041] In some embodiments, the receiving tray 8 includes a collecting plate, and an upwardly extending enclosure is provided at the edge of the collecting plate. By providing the enclosure, the gas entering from the first air inlet 4 of the second sealing box 3 during dust removal can be effectively prevented from blowing up the dust in the receiving tray 8.
[0042] The receiving tray 8 is generally arranged at the bottom of the second cavity, and the first air inlet 4 of the second sealed box 3 is located at a height higher than the top of the receiving tray 8, so as to further prevent the gas entering from the first air inlet 4 of the second sealed box 3 from blowing up the dust in the receiving tray 8 during dust removal. The receiving tray 8 can also be arranged at other positions except the bottom of the second cavity.
[0043] In some embodiments, the second sealed box 3 has an opening connected to the second cavity, and the dust removal device further includes a maintenance door, which is used to close or open the opening of the second sealed box 3. For example, when the maintenance door is opened, the receiving tray 8 can be easily taken out from the second cavity. In order to ensure the sealing performance of the second sealed box 3, a sealing ring can be provided on the edge of the maintenance door.
[0044] In some embodiments, the insufflation duct includes a first duct 6 and a second duct 7 .
[0045] The first pipe 6 has an open end and a sealed end, that is, the first pipe 6 has two ports, one of which is an open end and the other is a sealed end. The sealed end of the first pipe 6 is located in the first cavity, and the open end of the first pipe 6 is located outside the first sealed box 1, so that air can be blown into the first pipe 6 from the outside.
[0046] The second pipe 7 has two open ends, that is, the second pipe 7 has two ports, and both ports of the second pipe 7 are open ends. One open end of the second pipe 7 is connected to the portion of the first pipe 6 located inside the first cavity, and the other open end of the second pipe 7 extends into the third cavity. Since the second pipe 7 is connected to the first pipe 6, the gas blown in from the open end of the first pipe 6 will pass through the first pipe 6 and the second pipe 7 in sequence, and then enter the third cavity.
[0047] In some embodiments, the sealed end of the first pipe 6 is fixed to the inner wall of the first cavity, and since the open end of the first pipe 6 extends out of the first sealed box 1, the first pipe 6 is reliably fixed to the first sealed box 1. The sealed end of the first pipe 6 can be fixed to the inner wall of the first cavity by bonding, bolting, clamping, etc.
[0048] In some embodiments, Figure 3 As shown, the air baffle assembly includes a cover plate 9, a cylinder 10, a first bracket 11 and a second bracket 12.
[0049] The first bracket 11 is fixed in the first cavity. For example, the first bracket 11 is installed in the first cavity by bolts. The first bracket 11 can also be installed in other fixing methods. The cylinder 10 is installed on the first bracket 11, and the output end of the cylinder 10 is connected to the second bracket 12. The cover plate 9 is installed on the second bracket 12. The cover plate 9 is used to close or open the opening of the filter element 5. The cylinder 10 is used to drive the cover plate 9 to close or open the opening of the filter element 5.
[0050] In some embodiments, the number of cylinders 10 is two or more, and the operation of the cylinders 10 is controlled by a controller. The controller can be an existing product, and this embodiment does not involve improvements to the controller.
[0051] When the dust removal equipment is performing dust removal, the cylinder 10 drives the second bracket 12 to move upward, thereby driving the cover plate 9 to move upward, thereby opening the opening of the filter element 5; when removing dust on the surface of the filter element 5, the cylinder 10 drives the second bracket 12 to move downward, thereby driving the cover plate 9 to move downward, so that the cover plate 9 contacts the filter element 5, thereby closing the opening of the filter element 5.
[0052] In some embodiments, the filter element 5 is detachably mounted on the second sealed box 3, for example, by bolting or the like. Since the filter element 5 is detachably mounted, the filter element 5 can be easily replaced.
[0053] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
