Description

Technical Field

[0001] The invention relates to the technical field of bag dust removal, and in particular to a bag dust collector. Background Art

[0002] The so-called bag dust collector is also called a filter dust collector. It is a dry and efficient dust collector. It is a dust removal device that uses bag filter elements made of fiber woven materials to capture solid particles in dust-containing gases. Its working principle is that dust particles are intercepted when they collide with the fibers due to inertia when they pass around the filter cloth fibers.

[0003] The Chinese patent application with the publication number CN111514666A proposes a bag dust collector, including a dust collecting box, a horizontal fixed plate is arranged in the dust collecting box, a plurality of dust collecting bags are arranged under the fixed plate, a dust reduction mechanism is arranged in the dust collecting bag, and the dust reduction mechanism includes a fixed shaft inserted into the dust collecting bag, a plurality of fan groups sleeved on the fixed shaft and rotatably connected with the fixed shaft, and a disturbance component arranged on the fan group away from one end of the fixed shaft, the fan group rotates with the wind flowing up and down in the dust collecting bag, the disturbance component contacts the inner wall of the dust collecting bag, and a support frame fixed on the fixed shaft for supporting the dust collecting bag is arranged between two adjacent fan groups. It has the effect of efficiently utilizing wind energy to remove dust from the dust collecting bag without stopping the gas dust removal, thereby improving the working efficiency.

[0004] In order to avoid the problem that the existing device cannot carry out dust removal normally when cleaning the bag itself, the above device can achieve the dust removal of the bag itself while maintaining normal gas dust removal operation. However, in the specific implementation process, although the left and right adjacent bags are isolated by partitions, they are still in a large chamber as a whole, and the purpose of complete isolation is not achieved. Therefore, when a certain bag is cleaned, since other bags are still in the dust removal work, the cleaned dust may still be adsorbed on the outside by other bags when it falls on the public area below the chamber. Therefore, when cleaning different bags in turn, the cleaned dust will be retained in turn by the remaining different bags, and the dust removal quality is not good enough. Secondly, since the deep cleaning effect cannot be guaranteed, the bags are not fully cleaned, which will further affect their subsequent dust removal efficiency. Therefore, a bag dust collector is proposed here to solve the above problems. Summary of the invention

[0035] In the actual operation process, the device is first powered on, and the gas to be filtered is input into the housing 3 through the air inlet pipe 4. At this time, the first fan 51 works to generate suction. When the gas passes through the dust bag 55, the dust bag 55 filters the dust in the gas. The filtered gas is discharged to the outside of the housing 3 by the first fan 51 through the first pipe 52. In the above filtering work, the baffle 59 is between the two auxiliary frames 57, so the two auxiliary frames 57 are in a flow state. At this time, the dust bags 55 on the two platform plates 54 are put into dust removal work, ensuring the dust removal efficiency; When the gas passes through, the heavier dust particles are blocked by the dust bag 55 and fall downward into the dust collecting frame 2, while the lighter dust particles may be adsorbed on the outer surface of the dust bag 55. The long-term adsorption of dust will cause the passing rate of the dust bag 55 to decrease. When it is necessary to clean the dust on the outer side of the dust bag 55, the first motor 593 works and drives the first threaded rod 592 to rotate. After the first threaded rod 592 rotates, it drives the square plate 591 to move. The square plate 591 drives the baffle 59 to move. After the bottom of the auxiliary frame 57 under the dust bag 55 to be cleaned, the baffle 59 blocks the bottom opening of the auxiliary frame 57, thereby isolating the space under the dust bag 55 to be cleaned. While the above operations are being performed, the second motor 586 works and drives the second threaded rod 585 to rotate, the second threaded rod 585 drives the control board 583 to move, the control board 583 drives the first electric push rod 584 to move, the first electric push rod 584 drives the bracket plate 582 to move, the bracket plate 582 drives the main tube 598 to move, the main tube 598 drives the shunt tube 599 to move, the number of shunt tubes 599 is the same as the number of dust bags 55 on a single platform plate 54, when each shunt tube 599 is directly above the corresponding dust bag 55, the first electric push rod 584 pushes the bracket plate 582 downward, it can be seen from the above operations that at this time the shunt tube 599 drives the cylinder 581 to move downward and insert into the mounting ring 56, so as to isolate the space above the dust bag 55, so as to avoid the dust bag 55 on another platform plate 54 from interfering with the cleaning work when it is in normal dust removal operation; After the cylinder 581 is inserted into the mounting ring 56, the second fan 595 starts to blow air in the direction of the partition 596, and the air passes through the bellows 597, the main tube 598, the shunt tube 599 and the cylinder 581 in sequence, and then enters the dust bag 55 to perform a back-blowing operation, so that the dust on the outer surface of the dust bag 55 is blown off to achieve the purpose of cleaning. When the airflow enters the cylinder 581, the fan blade 588 rotates under the action of the airflow, and the fan blade 588 drives the round rod 587 to rotate, and the round rod 587 drives the swing frame 589 to rotate, and the swing frame 589 rotates. The extension plates 571 on both sides of 89 are extended to the outside of the swing frame 589 under the influence of the elastic force of the spring sheet 572 and contact the inside of the dust bag 55. When the round rod 587 rotates, the swing frame 589 will disturb the inside of the dust bag 55, thereby increasing the speed of dust falling. The cross section of the extension plate 571 is trapezoidal, so when the cylinder 581 is inserted into or leaves the mounting ring 56, the inclined surface on the extension plate 571 is squeezed, and the extension plate 571 moves to the inside of the swing frame 589, thereby ensuring that the cylinder 581 can be smoothly inserted into or leave the mounting ring 56; When the electromagnetic valve 64 on the drainage pipe 63 behind the cleaned dust bag 55 is in an open state, the dust blown off at this time can enter the rectangular frame 61 through the drainage pipe 63. At the same time, after the third fan 66 works, the suction strength of the fallen dust is further strengthened to ensure that the dust can fully enter the rectangular frame 61. When the dust enters, it is blocked by the filter screen plate 65. Since the filter screen plate 65 is in a downward tilted posture, the dust can slide down through the filter screen plate 65. At this time, in order to avoid the connection frame 62 and the dust collecting frame 2 being in a connected state and causing the dust stored in the dust collecting frame 2 to be agitated, the control plate 692 blocks the inner wall of the connection frame 62 at this time, and the sliding dust enters the top of the control plate 692 in the connection frame 62 for temporary storage. In order to ensure that the dust on the filter screen plate 65 can fully fall off, the third motor 68 drives the third threaded rod 67 to rotate after working. After the third threaded rod 67 drives the cleaning plate 69 to move, the dust on the filter screen plate 65 can be scraped off, thereby ensuring the passing rate of the airflow on the filter screen plate 65. During the movement of the above cleaning plate, in order to prevent dust from falling on the top of the cleaning plate and failing to fall off in time, each time the cleaning plate moves below the scraper 691, the bottom of the scraper 691 just contacts the top of the cleaning plate, thereby removing the dust on the top of the cleaning plate. Finally, when the cleaning work is completed, the second electric push rod 693 pushes the control plate 692 to the outside of the connecting frame 62 after working. After the control plate 692 moves to a position where it does not block the inner wall of the connecting frame 62, the dust on the control plate 692 can fall downward into the dust collecting frame 2. After the user opens the sealing door 575, the dust collecting frame 2 can be cleaned. The dust in the dust collection frame 2 is processed uniformly, and the operation process is simple and convenient. Through the above cleaning operation, when the dust collection bag 55 is cleaned, the other dust collection bags 55 can still maintain the dust collection work, avoiding the need to suspend the dust collection work during the cleaning work and affecting the dust collection work. On this basis, the dust generated during cleaning flows through an independent channel and finally falls into the dust collecting frame 2. The fallen dust will not be absorbed by the other dust collection bags 55, resulting in an unsatisfactory cleaning effect. Secondly, the dust after cleaning and the dust filtered out by the normal dust collection work are stored uniformly, which is convenient for the staff to handle uniformly.
