Description

TECHNICAL FIELD

[0001] The utility model belongs to dust remover technical field, concretely relates to a bag type dust collector. BACKGROUND

[0002] The bag type dust collector is a kind of dry filter dust device.It is suitable for trapping fine, dry, non-fibrous dust.Filter bag is made of woven filter cloth or non-woven felt, and dust-containing gas is filtered by the filtering effect of fiber fabric.When dust-containing gas enters the bag type dust collector, the dust with large particle size and specific gravity is settled down due to the action of gravity and falls into the ash bucket, and the gas containing fine dust is filtered by filter material, so that the gas is purified.However, during the process of being blocked by filter cloth bag, the fine dust is easily adsorbed on the surface of filter cloth bag, so that it is more and more, and the filter cloth bag pore is blocked, resulting in poor filtering effect of dust collector. Figure 1 As shown in the method, the upper end inlet 11 of each filter cloth bag 10 is connected with the compression main pipe 20 and the gas distribution pipe 21, and compressed air can be introduced into the inside, so as to realize backwashing of filter cloth bag and remove dust on the surface of filter cloth bag, which has certain cleaning effect on short filter cloth bag;But for the filter cloth bag with long length and large diameter, the above-mentioned backwashing mode is difficult to form effective and sufficient backwashing pressure, so it is difficult to effectively remove the dust attached to the surface of filter cloth bag. SUMMARY

[0003] The utility model aims at providing a bag type dust collector, which aims to solve the problem of excessive dust attached to the outer surface of the bag type dust collector, resulting in poor dust removal effect.

[0004] To solve the above technical problems, the utility model aims at realizing the following:

[0005] A bag type dust collector, comprising a dust collector main body and a plurality of filter cloth bags arranged in the dust collector main body, a pressure main pipe and a gas distribution pipe, a soft tube with a set length is arranged in each filter cloth bag, the upper end of the soft tube is fixedly installed on the gas outlet connector of the gas distribution pipe and is connected therewith, and the free end of the soft tube extends into the filter cloth bag.

[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: the free end of the soft tube extends to the middle and lower part of the filter cloth bag.

[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: the pressure main pipe is intermittently connected with compressed air.

[0008] The utility model discloses a compared with prior art outstanding and beneficial technical effect is: through setting up hose in filter cloth bag, and after the compressed air is passed to the hose, the free end of hose will be under the action of airflow serpentine to and fro swing, to beat the inner surface of filter cloth bag, under the action of beating, the dust adhered on the outer surface of filter cloth bag will be vibrated and fall off, and further solved the problem that the traditional backwashing mode is due to the cleaning effect of the problem of poor effect of insufficient washing pressure, and intermittent ventilation, that is, the intermittent beating filter cloth bag of hose, more gas source is saved. BRIEF DESCRIPTION OF DRAWINGS

[0009] Figure 1 It is prior art whole structure schematic diagram;

[0010] Figure 2 It is the whole structure schematic diagram of the utility model. DETAILED DESCRIPTION

[0011] In order to make the purpose, technical scheme and advantage of the present application more clear, the technical scheme in the embodiment will be clearly and completely described below in conjunction with the drawings in the embodiment, obviously, the described embodiment is only a part of the present application, rather than all the embodiments. Based on the embodiment given, all other embodiments obtained by the person skilled in the art without making creative efforts belong to the scope of protection of the present application.

[0012] In the description of the present application, it needs to be understood that the orientation or position relationship indicated by the terms "upper", "lower" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation to the present application.

[0013] In the description of the present application, the terms "first", "second" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated.

[0014] See Figure 2As shown, the application discloses a cloth bag type dust collector, which comprises a dust collector main body (including a frame support of the dust collector, an air inlet of the dust collector, an air outlet pipeline and other necessary accessory parts) and a plurality of filter cloth bags 10 arranged in the dust collector main body, and the structure of the dust collector is not different from the prior art, and thus will not be repeated here. Further, in the embodiment, a pressure main pipe 20 and a gas distribution pipe 21 are arranged, a soft pipe 50 with a set length is arranged in each filter cloth bag, the upper end of the soft pipe 50 is fixedly arranged on an air outlet joint 211 of the gas distribution pipe 21, the soft pipe 50 is communicated with the gas distribution pipe 21 through the air outlet joint 211, and the free end 51 of the soft pipe 50 extends to the inside of the filter cloth bag. Specifically, in order to better improve the cleaning effect of the filter cloth bag 10, the free end 51 of the soft pipe 50 extends to the middle and lower part of the filter cloth bag 1 in the filter cloth bag 10. Preferably, the soft pipe is a rubber soft pipe with a diameter of 8 mm and an inner diameter of 4 mm, and under a small air blowing flow, an obvious swing range can be generated, and the requirement for the pressure air source is reduced. After the soft pipe is arranged in the filter cloth bag and the compressed air is input into the soft pipe, the free end of the soft pipe swings back and forth in a snake shape under the action of the air flow, so as to beat the inner surface of the filter cloth bag. Under the action of beating, the dust attached to the outer surface of the filter cloth bag is vibrated and falls off, thereby solving the problem that the traditional backwashing mode has poor cleaning effect due to insufficient washing pressure.

[0015] Further, since the dust will have a substantial influence on the dust removal effect only after being attached to a certain thickness, the cleaning can be performed only before the dust removal effect is influenced. Therefore, the embodiment preferably intermittently inputs the compressed air into the pressure main pipe 20, so that the filter cloth bag is beaten by the soft pipe intermittently. On the one hand, the dust attached to the outer surface of the filter cloth bag can be effectively cleaned, and on the other hand, compared with continuous beating and cleaning, the air source is more saved, that is, the energy is more saved.

[0016] In order to better collect the falling dust, the lower part of the filter cloth bag 10 of the dust collector is preferably provided with a conical cylinder 30, the large end of the conical cylinder 30 is close to the lower part of the filter cloth bag 10, and the small end of the conical cylinder 30 is detachably connected with a dust collecting barrel 40. Then, the dust falling off from the outer surface of the filter cloth bag after being beaten by the soft pipe will be concentrated in the dust collecting barrel 40 under the action of gravity, and the dust in the dust collecting barrel 40 can be removed by regularly detaching the dust collecting barrel 40. It should be noted that the timing of inputting the compressed air is when the dust collector is temporarily stopped, so that the dust can be smoothly fallen off and fall into the dust collecting barrel 40.

[0017] The above embodiment is only a preferred embodiment of the application, and does not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape and principle of the application should be covered within the protection scope of the application.
