Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a dust collecting device for dust removal equipment. Background Art

[0002] Activated carbon is made from carbon-containing raw materials such as wood, coal and petroleum coke through pyrolysis and activation. It is usually a porous amorphous carbon in powder or granular form with strong adsorption capacity. Because a lot of particulate dust is generated in the activated carbon production process and floats in the air, the activated carbon production workshop needs to add dust removal equipment to remove dust from the workshop air.

[0003] Traditional dust removal equipment mainly installs multiple filter bags in the cylinder through a porous plate. The dust-containing gas enters from the lower side of the cylinder, passes through the filter bag, and is conducted upward along the middle of the filter bag. Finally, it is discharged from the air outlet set on the upper side of the cylinder. The dust is isolated by the filter bag and sticks to the outer wall of the filter bag. After a period of use, too much dust adheres to the surface of the filter bag, which will reduce the filtration efficiency. Therefore, the top of the filter bag needs to be connected to the compressed gas bag on the outside through the corresponding blowing pipe. After a period of dust removal, the machine needs to be stopped, and the filter bag is swollen by backblowing through the blowing pipe, and the dust adhering to the filter bag is blown off by wind, and collected and discharged along the ash guide hopper at the bottom of the cylinder. However, since activated carbon itself is a porous amorphous carbon with strong adsorption capacity in powder or granular form, the filter bag needs to be backblown to remove dust after a short period of use, which is very troublesome.

[0004] Therefore, designing an ash discharge port that can better connect to the dust removal equipment can not only perform preliminary dust removal and collection to reduce the ash content in the air, thereby extending the single use time of the filter bag and improving the dust removal efficiency and effect, but also facilitate the convenient and centralized collection of filtered dust by the dust collection device of the dust removal equipment. This is the research purpose of the utility model. Utility Model Content

[0005] In view of the technical problems existing in the above-mentioned prior art, the utility model provides a dust collection device for dust removal equipment, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the utility model is:

[0007] A dust collecting device for dust removal equipment, comprising:

[0008] The dust collecting cylinder is fixedly installed below the dust guide hopper of the dust removal equipment, and an ash collecting hopper coaxially arranged with the ash guide hopper is installed at the bottom of the dust collecting cylinder. The lower side of the dust collecting cylinder is connected to a dust-containing gas inlet, and the upper side is connected to the air inlet of the dust removal equipment through a corresponding air guide pipe;

[0009] A connecting pipe is installed at the discharge port of the ash guide hopper and extends downward to the ash collecting hopper below the dust-containing gas inlet;

[0010] A spiral material conveying member, wherein the cross section of the spiral material conveying member is L-shaped and is gradually spirally installed downward on the inner side wall of the dust collecting cylinder, and the lower end portion of the spiral material conveying member extends downward along the inner side wall of the dust collecting hopper to the middle of the dust collecting hopper;

[0011] A plurality of ash guide plates are provided, which are inclined and can be moved up and down and are installed on the outside of the connecting tube. The upper and lower ash guide plates are arranged alternately, and their downward inclined ends extend to the top of the adjacent spiral material transmission member, and their upward inclined ends are spaced apart from the adjacent spiral material transmission member.

[0012] A corresponding positioning convex edge is fixedly connected to the outer side of the connection tube below the ash guide plate, and a plurality of elastic members whose tops are connected to the ash guide plate are vertically fixedly connected to the positioning convex edge.

[0013] An elastic bellows is sleeved on the outer side of the connecting tube, and the two ends are respectively fixed to the corresponding positioning convex edge and the ash guide plate, and the elastic member is covered and arranged in the elastic bellows.

[0014] The bottom of the ash guide plate is connected with a corresponding dust collector, which comprises a roller shaft driven to rotate by a motor, and a plurality of turning blades are radially distributed and fixedly connected to the side wall of the roller shaft.

[0015] The dust-containing gas inlet is arranged on the side of the ash guide plate installed at the bottom end of the dust collecting cylinder, which is inclined downward; the air guide pipe is arranged on the side of the ash guide plate installed at the top end of the dust collecting cylinder, which is inclined downward.

[0016] A vibration motor wrapped with a corresponding protective film to prevent dust is fixedly connected below the ash guide hopper.

[0017] Advantages of the utility model:

[0018] 1) The utility model can be well connected to the dust discharge port of the dust removal equipment, which can not only perform preliminary dust removal and collection to reduce the dust content in the air, thereby extending the single use time of the filter bag in the dust removal equipment, improving the dust removal efficiency and effect, but also facilitate the convenient and centralized collection of filtered dust.

[0019] 2) The practicality of the present invention is that a connecting pipe connected to the ash guide hopper is coaxially arranged, and the connecting pipe extends downward to the ash collecting hopper. The connecting pipe can not only guide the accumulated ash collected in the dust removal mechanism to the ash collecting hopper for collection and discharge, but more importantly, it can be used to install ash guide plates staggered up and down, so that the dust-containing air forms a snake-shaped circulation, so as to achieve the effect of extending the gas circulation route, so that part of the dust sticks to the ash guide plate during the circulation process, effectively reducing the dust filter in the air; and when the gas circulates, part of the gas will hit the ash guide plate that is sleeved, and then cooperate with the elastic part to install the ash guide plate, so that the ash guide plate is easy to vibrate, and the vibration generated by the backblowing of the dust removal equipment is transmitted to the ash guide plate through the connecting pipe. The double vibration can enhance the falling of dust stuck on the ash guide plate, and guide the material along the inclined ash guide plate to the spiral material transmission part, and then transmit it to the ash collecting hopper for collection and discharge along the spiral material transmission part.

[0020] 3) The pipe opening of the connection pipe and the material storage end of the spiral material transfer plate of the utility model are both arranged in the dust collecting hopper below the dust-containing gas inlet, effectively preventing the dust conducted by the connection pipe and the spiral material transfer plate from being blown up again by the dust-containing gas and mixed into the dust-containing gas again, thereby ensuring the practical effect. The utility model can add a vibration motor under the ash guide hopper to enhance the efficiency and effect of the conduction of sticky dust accumulation, further improving the practical effect.

[0033] The pipe mouth of the connecting pipe 5 and the material storage end of the spiral material transfer member 6 of the utility model are both arranged in the ash collecting hopper 3 below the dust-containing gas inlet 101, which effectively prevents the dust conducted by the connecting pipe 5 and the spiral material transfer member 6 from being blown upward by the dust-containing gas again and mixed into the dust-containing gas again, thereby ensuring the practical effect.
