[0001] The utility model relates to the technical field of air box type pulse bag dust collectors, in particular to a novel air box type pulse bag dust collector. Background Art

[0002] The air box pulse bag dust collector is a type of bag dust collector. When the dust collector has been filtering dusty gas for a certain period of time, the dust cleaning controller will send a signal, and the lifting valve of the box chamber will start to close and cut off the filtering airflow. Then the pulse valve of the box chamber will open to remove the dust on the filter bag. The entire box design adopts the inlet and outlet main pipe structure. The ash hopper can be extended under the inlet main pipe, so that the incoming dusty flue gas can directly enter the expanded ash hopper to achieve the effect of pre-dust removal. Therefore, the air box pulse bag dust collector can not only handle dusty gas of general concentration, but also handle dusty gas of high concentration.

[0003] In the prior art, application number CN202022831491.8 proposes an air-box type pulse bag dust collector, wherein an air-box type pulse bag dust collector comprises a main shell, and legs are fixed at the four corners of the bottom of the main shell, an air inlet pipe is connected to one side below the main shell, a one-way mechanism is arranged in the air inlet pipe, an exhaust pipe is connected to one side above the main shell, a blow pipe is connected to the top of the main shell, one end of the blow pipe passes through the main shell and is connected to an electronic pulse valve, a support plate is fixed to one side above the main shell, an air bag is installed above the support plate, and the air bag is connected to the blow pipe, an upper plate is fixed in the main shell below the blow pipe, a plurality of dust filter bags are fixedly installed below the upper plate, a discharge pipe is connected to the bottom of the main shell, and a storage mechanism is arranged below the discharge pipe.

[0004] In the above patent, when a large amount of dust adheres to the dust filter bag, it is necessary to stop the air-box pulse bag dust collector, blow out gas through the air pipe, allow the gas to enter the dust filter bag, and blow away the dust attached to the surface of the dust filter bag. However, in the process of completing the above operation, it is necessary to stop the air-box pulse bag dust collector, resulting in the inability to filter the gas during the cleaning process of the dust filter bag. Therefore, a new air-box pulse bag dust collector is proposed. Utility Model Content

The bottom of the partition vertical plate 5 is an arc-shaped surface, and the arc-shaped surface is grooved upward in the vertical direction. The arc-shaped surface of the partition vertical plate 5 fits with the mounting shaft 7. The bottom of the partition vertical plate 5 is set to be an arc-shaped surface so that the partition vertical plate 5 and the mounting shaft 7 are completely fitted, thereby avoiding the gap between the partition vertical plate 5 and the mounting shaft 7 causing the gas containing dust to leak. A flip baffle 8 is fixedly arranged on the surface of the mounting shaft 7, and a dust baffle 10 is fixedly arranged inside the installation box 1. The dust baffle 10 has a U-shaped structure and is made of metal. There are two dust baffles 10, two of which are provided. The dust baffles 10 are respectively fixedly mounted on the left and right side walls of the mounting box 1.

By opening the electromagnetic valve on the air blowing pipe 17 aligned with the left dust filter bag 21, or by opening the electromagnetic valve on the air blowing pipe 17 aligned with the right dust filter bag 22, the gas in the air bag 16 is conveniently ejected through the cleaning air pipe 18 on the left or the cleaning air pipe 18 on the right.Thereby, it is convenient to clean the left dust filter bag 21 or the right dust filter bag 22. The servo motor 6 drives the flip baffle 8 to flip inside the installation box 1 through the installation shaft 7, so that the flip baffle 8 contacts the dust outlet baffle 10 on the left side, or contacts the dust outlet baffle 10 on the right side, so that the flip baffle 8 and the partition vertical plate 5 separate the air inside the installation box 1, so that the gas enters the right side of the partition vertical plate 5, or enters the left side of the partition vertical plate 5, and the gas can be filtered by the left dust filter bag 21 or the right dust filter bag 22. At this time, the solenoid valve on the left air blowing pipe 17 is controlled to be opened, or the solenoid valve on the right air blowing pipe 17 is controlled to be opened, that is, The left dust filter bag 21 or the right dust filter bag 22 can be cleaned, and the blown dust enters the dust baffle 10 under the blocking effect of the partition vertical plate 5 and the flip baffle 8, and enters the dust collecting hopper 3 through the outlet 12, so that when the gas is filtered by the left dust filter bag 21, the dust attached to the surface of the right dust filter bag 22 can be cleaned, and when the gas is filtered by the right dust filter bag 22, the dust attached to the surface of the left dust filter bag 21 can be cleaned, thereby avoiding the need to stop the air box pulse bag dust collector for too long, thereby avoiding the situation where the air box pulse bag dust collector cannot filter the gas during the cleaning process.

[0023] Specifically, an exhaust assembly is provided at the rear side of the installation box 1, and the exhaust assembly includes a left air outlet pipe 23 and a right air outlet pipe 24, both of which are fixedly installed at the rear side of the installation box 1, and solenoid valves are fixedly installed on the left air outlet pipe 23 and the right air outlet pipe 24, and a three-way pipe 25 is fixedly installed between the air outlet ends of the left air outlet pipe 23 and the right air outlet pipe 24, and an exhaust pipe 15 is fixedly arranged inside the three-way pipe 25, so that by opening the solenoid valve on the left air outlet pipe 23 or the right air outlet pipe 24, the gas filtered by the left dust filter bag 21 or the right dust filter bag 22 is discharged, so that when the left dust filter bag 21 or the right dust filter bag 22 filters the gas containing dust, the dust attached to the right dust filter bag 22 or the left dust filter bag 21 can be cleaned, so that the air-box type pulse bag dust collector does not need to stop during the cleaning process, thereby making the air-box type pulse bag dust collector more convenient to use.

[0024] The novel air box pulse bag dust collector is connected to 220V mains electricity, and the main controller can be a conventional known device for control such as a computer.

[0025] During use: the dust-containing gas enters the interior of the installation box 1 through the installation box 1, and the entered gas is filtered by the left dust filter bag 21, and the filtered gas enters the top of the left fixed plate 19. At this time, the solenoid valve on the right air outlet pipe 24 is opened, and the solenoid valve on the left air outlet pipe 23 is closed, so that the filtered gas enters the interior of the three-way pipe 25 through the left air outlet pipe 23, and enters the exhaust pipe 15 through the three-way pipe 25 for discharge. When too much dust adheres to the surface of the left dust filter bag 21, the output end is driven by the partition vertical plate 5 to drive the installation shaft 7 to rotate, so that the installation shaft 7 drives the flip baffle 8 to flip to the left side, so that the flip baffle 8 is separated from the dust outlet baffle 10 on the right and contacts with the dust outlet baffle 10 on the left. At this time, the internal gas entering the installation box 1 through the air inlet pipe 2 is between the flip baffle 8 and the partition vertical plate Under the partitioning effect of plate 5, it enters the right side of the partition vertical plate 5, so that the right dust filter bag 22 filters the dust in the gas, and the filtered gas enters the top of the right fixed plate 20. At this time, the solenoid valve on the left air outlet pipe 23 is opened, and the solenoid valve on the right air outlet pipe 24 is closed, so that the filtered gas passes through the left air outlet pipe 23 into the inside of the three-way pipe 25 and is discharged through the exhaust pipe 15. At the same time, the solenoid valve on the blowing pipe 17 vertically aligned with the left dust filter bag 21 is opened, so that the compressed gas in the air bag 16 enters the inside of the blowing pipe 17 on the left, and the compressed gas is sprayed into the inside of the left dust filter bag 21 through the cleaning air pipe 18 on the left, so that the dust attached to the left dust filter bag 21 is blown off. Similarly, when the gas is filtered by the left dust filter bag 21, the dust attached to the right dust filter bag 22 can be blown.

[0026] In summary, the novel air box pulse bag dust collector drives the flip baffle 8 to flip inside the installation box 1 through the servo motor 6 via the installation shaft 7, so that the flip baffle 8 contacts the dust outlet baffle 10 on the left side, or contacts the dust outlet baffle 10 on the right side, so that the flip baffle 8 and the partition vertical plate 5 separate the air inside the installation box 1, so that the gas enters the right side of the partition vertical plate 5, or enters the left side of the partition vertical plate 5, and can be filtered by the left dust filter bag 21 or the right dust filter bag 22. At this time, the solenoid valve on the left air blowing pipe 17 is controlled to open, or the solenoid valve on the right air blowing pipe 17 is controlled to open, so that the left dust filter bag 21 or the right dust filter bag 22 can be filtered. The dust filter bag 22 is cleaned, and the blown dust enters the dust outlet baffle 10 under the blocking effect of the partition vertical plate 5 and the flip baffle 8, and enters the dust collecting hopper 3 through the outlet 12, so that when the gas is filtered by the left dust filter bag 21, the dust attached to the surface of the right dust filter bag 22 can be cleaned, and when the gas is filtered by the right dust filter bag 22, the dust attached to the surface of the left dust filter bag 21 can be cleaned, thereby avoiding the need to stop the air box pulse bag dust collector for too long, thereby avoiding the situation where the gas cannot be filtered during the cleaning process of the air box pulse bag dust collector, and is used to solve the problems raised in the above-mentioned background technology.
