Description

Technical Field

[0001] The invention relates to the technical field of dust removal equipment, in particular to a dust transport pipeline for dust removal equipment. Background Art

[0002] The design of dust transport pipelines must follow the principles of efficiency, economy, safety, and easy maintenance. Core parameters include flow rate and pressure. The airflow speed must be set according to the characteristics of the dust to avoid blockage and wear, while ensuring negative pressure to capture dust. The pipe diameter and layout must match the air volume requirements, and elbows and diameter changes must be reduced to reduce resistance.

[0003] According to Chinese Patent Publication No. CN112044205B, a blockage-resistant waste gas treatment device for a clinker cement production line is provided, comprising a waste gas treatment box for treating waste gas, a group-pipe heat exchange mechanism for exchanging and absorbing heat in the waste gas, and an exhaust blockage prevention mechanism for humidifying and removing dust from the waste gas inside the pipeline in real time. The bottom of the waste gas treatment box is fixedly connected to a support leg, and the group-pipe heat exchange mechanism is disposed on the waste gas treatment box, and relates to the field of cement production. This blockage-resistant waste gas treatment device for a clinker cement production line is designed to address the blockage problem existing in the existing cement production process. Longer heat exchange pipes are designed to ensure sufficient heat exchange, and a continuous, non-evaporating flowing water film is designed to address the cause of blockage. This effectively solves the problem of high waste gas temperature and high dust content in conventional cement production lines, which causes dust to adhere to the pipes during heat exchange in long pipes, causing corrosion and blockage.

[0004] At present, the existing dust transport pipes for dust removal equipment and the above-mentioned cases are not convenient to dock and control during use. The dust transport pipes for dust removal equipment often need to adjust the angle to prevent blockage. The traditional elbow processing method cannot be quickly installed and fixed, so improvements are made to the above-mentioned problems. Summary of the Invention

[0035] Boiler electric bag dust collectors can be connected with dust transport pipelines.

[0036] The working principle is as follows: when in use, the ash is guided to the pneumatic inspection valve 9 and the dust transport pipe structure 12 through the dust collector. Part of the dust is guided to the feeder 10 through the pneumatic inspection valve 9 and the expansion joint 11. It is then transferred to the scraper conveyor 7 through the feeder 10 to realize the transmission of the ash. At this time, the remaining ash or the ash is processed in a low-pressure state, and then it is processed uniformly by the bulk machine 8. When the high-pressure gas carries dust, it is guided to the first down-draw dense phase silo pump 1, the second down-draw dense phase silo pump 2, and the third down-draw dense phase silo pump 5 through the dust transport pipe structure 12, and then it is processed uniformly by the gas storage tank 3. The arrangement of the dust transport pipeline structure 12 facilitates the connection between the first down-draw dense phase silo pump 1, the second down-draw dense phase silo pump 2, and the third down-draw dense phase silo pump 5 and the dust collector, and facilitates rapid docking processing. Through the structural arrangement of the pneumatic inspection valve 9, the pneumatic inspection valve 9 is arranged at the lower end of the dust collector for guiding and draining the ash material. The lower end of the pneumatic inspection valve 9 is connected to the expansion joint 11 and the feeder 10 for transporting the ash material, so that the ash material reaches the scraper conveyor 7 and is then guided to the bulk machine 8 for unified collection and processing of the ash material. At the same time, the dust collector is also connected to the first down-draw dense phase silo pump 1, the second down-draw dense phase silo pump 2, and the third down-draw dense phase silo pump 5 respectively through the dust transport pipeline structure 12, and the side ends of the first down-draw dense phase silo pump 1, the second down-draw dense phase silo pump 2, and the third down-draw dense phase silo pump 5 are connected to the air storage tank 3, which can transport the powder material and carry out continuous ash material processing. Pressing the adjustment rod 42 causes the pawl 41 to move. The pawl 41 is hinged to the limit control plate 36 via the docking end frame 39, and the angle can be changed by pressing. At this time, the spring 40 is squeezed and contracted, and the pawl 41 cancels the limit engagement with the ratchet 46. The limit position is limited by the limit block 37. Afterwards, the user rotates and presses the control lever 43, which drives the rotating guide plate 44 to move, causing the rear seat 45 and the ratchet 46 to rotate as a whole. The rear seat 45 and the ratchet 46 rotate relative to the limit plate 22 by rotating the control plate 34 and the connecting shaft 33. At this time, the movable adjustment rod 24 moves in coordination with the adjustment unit 26. After reaching the appropriate position, the adjustment lever 42 is released. At this time, the pawl 41 is reset under the action of the spring 40, so that the pawl 41 is again limited by the ratchet 46. Then, the tightening screw cap 23 is screwed, so that the tightening screw cap 23 fixes the movable adjustment rod 24 to the limit plate 22, thereby limiting the adjustment unit 26. Among them, when the adjustment unit 26 moves, it drives the adjustment end frame 27 to move and cooperate, so that the adjustment mechanism 15 rotates on the docking ring sleeve 17, so that the connecting pipe 28 is rotated and adjusted through the ball tube 29, thereby changing the docking position. The docking ring sleeve 17 is fixed to the matching end seat 47 by the fastening bolts 19 to achieve overall connectivity. After that, the construction can be completed by simply docking the upper end of the connecting pipe 28 with the pipe body.

[0037] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
