Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, specifically a dust transport pipeline for dust removal equipment. Background Technology

[0002] The design of dust transport pipelines should follow the principles of high efficiency, economy, safety and ease of maintenance. Core parameters include flow rate and pressure. The airflow speed should 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 should match the air volume requirements and reduce bends and diameter changes to reduce resistance.

[0003] According to Chinese Patent Publication No. CN112044205B, an anti-clogging clinker cement production line exhaust gas treatment device is provided. It includes an exhaust gas treatment box for exhaust gas treatment, a multi-tube heat exchange mechanism for exchanging and absorbing heat from the exhaust gas, and an exhaust anti-clogging mechanism for humidifying and real-time dust removal of the exhaust gas inside the pipes. The bottom of the exhaust gas treatment box is fixedly connected to support legs, and the multi-tube heat exchange mechanism is mounted on the exhaust gas treatment box. This device relates to the cement production field. Addressing the clogging problems existing in current cement production processes, this anti-clogging clinker cement production line exhaust gas treatment device designs a longer heat exchange pipe for sufficient heat exchange. Furthermore, it addresses the causes of clogging by designing a continuous, non-vaporizing flowing water film, thereby effectively solving the problems of high exhaust gas temperature and high dust content in general cement production lines, where dust easily adheres to the pipes during heat exchange in long pipes, causing pipe corrosion and clogging.

[0004] Currently, existing dust transport pipes used in dust removal equipment, as well as the aforementioned cases, are inconvenient to connect and control during use. Dust transport pipes used in dust removal equipment often require angle adjustments to prevent blockages. Traditional elbow treatment methods cannot be quickly installed and fixed. Therefore, improvements are needed to address these issues. Summary of the Invention

[0005] To address the problems in the prior art, the present invention provides a dust transport pipeline for dust removal equipment.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: a dust transport pipeline for dust removal equipment, including a first downward-drawing dense phase chamber pump, a second downward-drawing dense phase chamber pump, and a third downward-drawing dense phase chamber pump. The first downward-drawing dense phase chamber pump, the second downward-drawing dense phase chamber pump, and the third downward-drawing dense phase chamber pump have the same structure. The side ends of the first downward-drawing dense phase chamber pump, the second downward-drawing dense phase chamber pump, and the third downward-drawing dense phase chamber pump are all connected to a gas storage tank. The upper ends of the first downward-drawing dense phase chamber pump, the second downward-drawing dense phase chamber pump, and the third downward-drawing dense phase chamber pump are connected through a dust transport pipeline structure. An expansion joint is provided at the lower end of the pneumatic maintenance valve, and a feeder is provided at the lower end of the expansion joint. A scraper conveyor is installed at one end, and the lower end of the scraper conveyor is connected to the bulk loader. The dust transport pipeline structure is connected to the upper end of the pneumatic maintenance valve. The ash material is guided to the pneumatic maintenance valve and the dust transport pipeline structure through the dust collector. Some dust is guided to the feeder through the pneumatic maintenance valve and the expansion joint. The feeder then transfers the ash material to the scraper conveyor. This is the handling of the remaining ash material or the material under low pressure. Afterwards, it is processed uniformly by the bulk loader. When high-pressure gas carries dust, it is guided to the first, second, and third lower-inlet dense phase silo pumps through the dust transport pipeline structure. Afterwards, it is processed uniformly by the gas storage tank. The dust transport pipeline structure allows for changing the docking angle, with the docking components and pipe body components engaging in a limiting docking. A pawl and ratchet cooperate to lock the docking unit. The lower end of the docking unit connects to the docking ring and fixed seat, and an adjusting rod controls the position of the pawl and ratchet for locking control. A pneumatic maintenance valve, located at the lower end of the dust collector, guides the ash material. The lower end of the pneumatic maintenance valve connects to the expansion joint and feeder for ash material transport, ensuring the ash reaches the scraper conveyor and is then guided to the bulk loader for unified collection and processing. Simultaneously, the dust collector connects to the first, second, and third lower-pump dense phase silo pumps via the dust transport pipeline structure.

The ash material is guided by the dust collector to the pneumatic maintenance valve and the dust transport pipeline structure. Some of the dust is guided to the feeder through the pneumatic maintenance valve and the expansion joint. The feeder then transmits the ash material to the scraper conveyor, thus realizing the transmission of the ash material. At this time, it is the remaining ash material or the processing under low pressure. Afterwards, it is processed uniformly by the bulk loading machine. When the high-pressure gas carries dust, it is guided by the dust transport pipeline structure to the first lower-type dense phase silo pump, the second lower-type dense phase silo pump, and the third lower-type dense phase silo pump 5.

The lower end of the pneumatic inspection valve connects to the expansion joint and the feed... The material handling unit is connected to the dust collector for transporting ash materials, allowing them to reach the scraper conveyor and then be guided to the bulk material handling unit for unified collection and processing. Simultaneously, the dust collector is connected to the first, second, and third lower-pump dense phase silo pumps 5 via dust transport pipelines. The sides of these pumps are also connected to an air storage tank, enabling continuous ash material transport and processing.

[0036] The working principle is as follows: During use, the ash material is guided by the dust collector to the pneumatic maintenance valve 9 and the dust transport pipeline structure 12. Some of the dust is guided by the pneumatic maintenance valve 9 and the expansion joint 11 to the feeder 10, and then transferred to the scraper conveyor 7 by the feeder 10 to realize the transfer of ash material. At this time, it is the remaining ash material or the processing under low pressure. Afterwards, it is processed uniformly by the bulk loader 8. When the high pressure gas carries dust, it is guided by the dust transport pipeline structure 12 to the first lower-type dense phase silo pump 1, the second lower-type dense phase silo pump 2, and the third lower-type dense phase silo pump 5. Afterwards, it is processed uniformly by the gas storage tank 3. The dust transport pipeline structure 12 facilitates the connection between the first lower-type dense phase silo pump 1, the second lower-type dense phase silo pump 2, and the third lower-type dense phase silo pump 5 and the dust collector, enabling rapid docking. The pneumatic maintenance valve 9, located at the lower end of the dust collector, guides the ash material. Its lower end connects to the expansion joint 11 and the feeder 10 for ash material transport, allowing the ash material to reach the scraper conveyor 7 and then be guided to the bulk loader 8 for unified collection and processing. Simultaneously, the dust collector is also connected to the first lower-type dense phase silo pump 1, the second lower-type dense phase silo pump 2, and the third lower-type dense phase silo pump 5 via the dust transport pipeline structure 12. Furthermore, the sides of the first lower-type dense phase silo pump 1, the second lower-type dense phase silo pump 2, and the third lower-type dense phase silo pump 5 are connected to the air storage tank 3, enabling continuous ash material transport and processing. Pressing the adjusting rod 42 causes the pawl 41 to move. The pawl 41 is hinged to the limit control plate 36 via the docking end bracket 39. The angle can be changed by pressing, and the spring 40 is compressed and contracted at this time. At this time, the pawl 41 is no longer engaged with the ratchet 46, and the extreme 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 ratchet 46 to rotate as a whole. The rear seat 45 and ratchet 46 rotate relative to the limiting plate 22 through the rotation of the control plate 34 and the connecting shaft 33. At this time, the movable adjustment lever 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 to the ratchet 46. Then, the fastening cap 23 is tightened to fix the movable adjustment lever 24 to the limiting plate 22, thereby performing the limiting work of the adjustment unit 26. When the adjustment unit 26 moves, it drives the adjustment end frame 27 to move in coordination, so that the adjustment mechanism 15 rotates on the docking ring sleeve 17, and the connecting pipe 28 rotates and is adjusted through the ball tube 29, thereby changing the docking position. The docking ring sleeve 17 is fixed to the mating end seat 47 by the fastening bolt 19 to achieve overall connection. Then, the construction can be completed by simply docking the upper end of the connecting pipe 28 with the pipe body.
