Embodiment 1

[0032] Such as Figure 1 to Figure 3 As shown, the industrial dust removal device includes a frame 1 and a detachable filter bag 4 installed in the frame 1. The two ends of the frame are provided with vibration motors 11 and power lines connected to external power sources. The vibration motors 11 at both ends are connected by connecting rods 2. The connecting rod 2 is provided with a protrusion 3 in contact with the outer surface of the filter bag 4. After the vibration motor 11 is powered on, the vibration is transmitted to the protrusion 3 through the connecting rod 2, and the filter bag 4 that is in contact with the upper part of the protrusion 3 is tapped. Make the dust on the surface of the filter bag 4 fall into the ash hopper in time to ensure the dust removal effect of the filter bag in the later stage.

[0033] Such as image 3 As shown, one end of the filter bag 4 is opened as an air inlet, and one end is sewn together. The filter bag includes a base cloth layer 41 ...

Embodiment 2

[0044] This dedusting device is identical in structure with embodiment 1, but the preparation method of filter bag is different:

[0045] Step 1: The polytetrafluoroethylene fibers and glass fibers with a volume ratio of 8:2 are carded, twisted and plyed into warps with a wire diameter of 0.15-0.2 mm; the polyester fibers with a volume ratio of 8:2 and metal conductive fibers are respectively carded and then twisted and woven into weft threads with a wire diameter of 0.2-0.3mm;

[0046] Step 2: Weave the warp and weft threads obtained in step 1 through a loom to obtain a base fabric, the warp thread density is 15-20 threads / cm, and the weft thread density is 10-15 threads / cm;

[0047] Step 3: 35 parts of polyurethane, 40 parts of silicone resin, 20 parts of perfluoroalkyl ethyl acrylate, 7 parts of activated carbon, 5 parts of magnesium hydroxide, 4 parts of antimony oxide, tert-butylhydroquinone derivative ( 8 parts of DTBHO) and 15 parts of silicone oil were mixed and stirr...

Embodiment 3

[0054] This dedusting device is identical in structure with embodiment 1, but the preparation method of filter bag is different:

[0055] Step 1: The polytetrafluoroethylene fibers and glass fibers with a volume ratio of 7:3 are carded, twisted and plyed into warps with a wire diameter of 0.15-0.2mm; the polyester fibers with a volume ratio of 7:3 and metal conductive fibers are respectively carded and then twisted and woven into weft threads with a wire diameter of 0.2-0.3mm;

[0056] Step 2: Weave the warp and weft threads obtained in step 1 through a loom to obtain a base fabric, the warp thread density is 15-20 threads / cm, and the weft thread density is 10-15 threads / cm;

[0057] Step 3: 20 parts of polyurethane, 20 parts of silicone resin, 10 parts of perfluoroalkyl ethyl acrylate, 5 parts of activated carbon, 3 parts of magnesium hydroxide, 2 parts of antimony oxide, tert-butyl hydroquinone derivative ( 5 parts of DTBHO) and 10 parts of silicone oil were mixed and stirr...

Abstract

The invention discloses an industrial dust removing device. The industrial dust removing device comprises a framework and a detachable filter bag mounted in the framework, wherein vibrating devices are arranged at two ends of the framework and connected through connecting rods; bumps in contact with the outer surface of the filter bag are arranged on the connecting rods; dust falls off timely since the filter bag is flapped by the bumps on the filter rod; the filter bag at least comprises a base fabric layer and a dust meeting layer; the base fabric layer and the dust meeting layer are connected by needling; after the base fabric layer is subjected to liquid immersion treatment, the surface of the base fabric layer is pre-coated to form a coating layer; one surface, connected with the basefabric layer, of the dust meeting layer, is subjected to gigging treatment; by precoating the surface layer of the base fabric layer with one coating layer, the defect of low dust removing efficiencyat an earlier stage of a novel filter material is overcome; one surface, connected with the base fabric layer, of the dust meeting layer, is mechanically gigged to form a layer of short threads for covering texture pores; when the filter material is back washed, a precoated coating layer powder flushed from the surface of the base fabric can be captured, so that effect loss of a precoated coatinglayer along with the increase of back wash times is avoided.

Description

technical field [0001] The invention relates to an industrial dust removal device, which belongs to the field of industrial dust removal and filtering equipment. Background technique [0002] In cement, steel, petrochemical and other fields, it is necessary to filter dust or smoke during the production process. Dust filter bag is a kind of efficient dust filter material, which has good ventilation performance, high dust removal efficiency, and has certain acid resistance. Alkali and heat resistance. The existing dust removal equipment has the problem that the dust removal is not timely, which leads to the reduction of the dust removal effect of the filter bag in the later stage. On the other hand, after the filter material of the cloth bag is initially formed by weaving or non-woven technology, it generally requires necessary post-processing. Among them, fine dust with a certain particle size distribution is selected to adhere to the surface of the filter material in advan...
