Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a bag filter for mining. Background Technique

[0002] During the production, processing or transportation of mines, dust is easily generated, resulting in reduced visibility of the working environment, dust inhalation pollution and environmental pollution. Therefore, using a dust collector for dust removal is of great benefit to ensuring environmental and air cleanliness, reducing pollution hazards, and collecting by-products.

[0003] At present, most dust collectors used in mines have the following problems: Since most of them only have one air inlet, and the air inlet is fixed and cannot be rotated, and the dust collector is heavy, it is not easy to move after the dust collector is installed in the mine.

Specific embodiments

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1

[0026] Please refer to Figure 1 and Figure 4 , a bag filter for mining, comprising a dust collector body and a feed part rotatably installed on the dust collector body; the feed part includes an L-shaped feed pipe 1, a motor 2 installed on the top of the dust collector body, a transmission shaft connected to the motor through a coupling, a main gear 3 connected to the transmission shaft, an auxiliary gear 4 connected to the feed pipe, and a protective cover 5 installed on the dust collector body; a feed port is provided at the top of the dust collector body, a boss 6 is provided in the feed port, the feed pipe 1 is rotatably connected to the boss 6 through a rotary bearing 7, the main gear 3 meshes with the auxiliary gear 4, and the motor 2, the main gear 3 and the auxiliary gear 4 are located in the protective cover 5.

[0027] As Figure 1 , Figure 2 shown, the dust collector body includes a frame 8, a box body 9 connected to the frame, a plurality of mounting holes opened on the front side of the box body, folding filter cartridges 10 threadedly connected to the mounting holes, and a hopper 11 installed in the box body and located below the folding filter cartridges. Any one of the upper folding filter cartridges 10 is located between the two lower folding filter cartridges. As Figure 3As shown in the figure, the outer end of the folded filter cartridge is an end cap, and the inner end is a bottom cap. A folded filter element is connected between the end cap and the bottom cap. A groove is provided on the inner wall of the rear part of the box body 9. The bottom cap at the inner end of the folded filter cartridge 10 is threadedly connected to the groove. The end cap at the outer end of the folded filter cartridge 10 is threadedly connected to the mounting hole. A first sealing ring 13 is provided near the end cap on the folded filter cartridge 10. That is, the first sealing ring 13 is in contact with the inner wall of the mounting hole to prevent dust from leaking out. The dust collector body further includes an exhaust fan 14 installed on the frame. The exhaust fan 14 is connected to the lower part of the box body 9 through a pipeline 15. A sewage discharge pipe 16 is connected to the bottom of the box body 9. A control valve 18 is connected to the sewage discharge pipe 16 for controlling the opening and closing of the sewage discharge pipe.

[0028] In this embodiment, a filter cover 17 is installed around the mouth of the pipeline 15 of the box body 9. The air can be further filtered through the filter cover 17.

[0029] In this embodiment, a dust sensor 19 is installed near the inlet of the feed pipe 1. When particles and molecules are irradiated by light, light scattering will occur, and at the same time, part of the energy of the irradiated light will be absorbed. When a beam of parallel monochromatic light is incident on the measured particle field, it will be affected by scattering and absorption around the particles, and the light intensity will be attenuated. In this way, a light source can be provided on one side of the dust collector body to irradiate the mine field, and the relative attenuation rate of the incident light passing through the measured concentration field can be obtained. The magnitude of the relative attenuation rate can basically linearly reflect the relative concentration of dust in the measured field. The magnitude of the light intensity is proportional to the strength of the electrical signal after photoelectric conversion. Therefore, the relative attenuation rate can be obtained by measuring the electrical signal through the dust sensor, so as to sense the direction with more dust and transmit the signal to the total controller, and the total controller controls the motor to work and drives the feed pipe to rotate. In addition, the dust sensor may not be provided, and the motor can be controlled by the worker according to the on-site situation through the worker's observation.

[0030] The working principle of this embodiment is as follows:

[0031] After the dust collector body is installed in the mine field, the air outlet pipe on the fan is connected to the air supply pipeline. The motor can be controlled according to the situation of the mine field to drive the feed pipe to rotate, so as to adjust the direction of the feed pipe. Then start the induced draft fan to suck the air in the mine field into the box body. Through the filtration of the folded filter cartridge, the dust in the air adheres to the folded filter cartridge, and the air passes through the folded filter cartridge and is discharged after being filtered by the filter cover again. When the dust on the folded filter cartridge is full, the folded filter cartridge can be taken out for cleaning or replacement. When there is a large amount of dust accumulated in the box body, the control valve can also be opened to discharge the dust in the box body through the sewage discharge pipe.

[0032] Embodiment 2

[0033] On the basis of Embodiment 1, a second sealing ring 20 is provided at the contact between the feed pipe 1 and the boss 6, and a third sealing ring 21 is provided at the contact between the feed pipe 1 and the protective cover 5.

[0034] Through the action of the second sealing ring, the sealing performance between the feed pipe and the box body can be improved. Through the action of the third sealing ring, the sealing performance between the feed pipe and the protective cover can be improved.
