Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of baghouse dust collectors, specifically a rotary jet baghouse dust collector. Background Technology
[0002] Pulse-jet baghouse dust collectors are widely used high-efficiency filtration devices in the industrial dust removal field. They purify dust-laden gas by intercepting dust through filter bags and cleaning it with a pulse-jet system. Dust-laden gas enters from the dust collector's inlet and passes through the filter bags. As the gas passes through the filter bags, the dust is trapped on the outer surface of the filter bags, while the clean gas exits through the filter bags. When dust accumulates on the surface of the filter bags, causing the resistance to rise to a set value, the pulse valve releases high-pressure gas, which instantly impacts the filter bags, causing the dust to fall into the dust hopper.
[0003] The high-pressure gas released by the pulse valve is blown towards the filter bag below through the nozzle of the blow pipe. This single-angle blowing can cause the top of the filter bag to be over-cleaned, while the middle and lower parts may be under-cleaned, resulting in poor cleaning efficiency.
[0004] In view of this, we propose a rotary jet bag filter dust collector. Utility Model Content
[0005] The purpose of this invention is to provide a rotary jet bag filter to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A rotary jet bag filter dust collector includes a bag filter body, a filter bag inside the bag filter body, a jet pipe above the filter bag, an air outlet pipe connected to the bottom end of the filter bag and located above the filter bag, a pulse valve on one side of the bag filter body, the output end of the pulse valve extending into the bag filter body and communicating with the jet pipe, a rotating ring fixedly connected to the inner wall of the air outlet pipe, a rotating disk rotatably connected to the side wall of the rotating ring, multiple air outlet holes on the bottom surface of the rotating disk, a support rod fixedly connected to the surface of the rotating disk, and multiple drive blades fixedly connected to the side wall of the support rod.
[0008] During dust removal, the high-pressure gas discharged through the pulse valve flows into the air outlet pipe and along the side wall of the drive fan blade on the side wall of the support rod, allowing the drive fan blade to rotate. The drive fan blade, in conjunction with the support rod, rotating disk, and rotating ring, causes the rotating disk to start rotating. The high-pressure gas discharged from the air outlet on the surface of the rotating disk rotates and sprays towards the filter bag located below the air outlet pipe, so that the airflow dynamically surrounds and sprays towards the filter bag. The airflow covers the entire circumference of the filter bag with the rotation trajectory, avoiding blind spots, improving cleaning efficiency, and making it simple and fast.
[0009] Preferably, an air-breaking cone is fixedly connected to the top of the drive fan blade;
[0010] By setting up an air-breaking cone, when the high-pressure airflow flows into the interior of the exhaust pipe, the air-breaking cone will break the airflow, and the broken airflow will be blown along the side wall of the air-breaking cone towards the drive fan blades below, which will facilitate the rotation of the drive fan blades.
[0011] Preferably, the surface of the rotating disk has multiple beveled holes;
[0012] The angled holes allow the jetting airflow to be directed at the filter bag at an angle, while the rotating disc shapes this jetting airflow into a spiral trajectory that can cover the entire length of the filter bag, further improving the dust removal efficiency.
[0013] Preferably, the sidewall of the rotating ring is provided with a plurality of ball grooves, and the inner wall of the ball grooves is rotatably connected to a rotating ball;
[0014] By using a combination of ball grooves and rotating balls, the rotating balls roll along with the rotating disk as it rotates, improving the smoothness of the rotating disk's rotation.
[0015] Preferably, a connecting block is fixedly connected to the bottom surface of the air outlet pipe, and a connecting rod is fixedly connected to the bottom surface of the connecting block, and a cleaning plate is fixedly connected to the top surface of the connecting rod;
[0016] As the rotating disc rotates, its bottom surface slides along the surface of the cleaning plate, which scrapes away the dust accumulated on the disc's surface, preventing the disc from clogging the air vents and beveled holes due to dust buildup.
[0017] Preferably, the cleaning plate is made of a flexible material;
[0018] The use of flexible materials can prevent the cleaning plate from scratching the bottom surface of the rotating disk, thus extending the service life of the rotating disk.
[0019] Preferably, the rotating disk is made of carbon steel;
[0020] The rotating disc is made of carbon steel. Carbon steel has high strength and good compressive strength, which can effectively resist the blowing pressure. It is also low in cost, has excellent machinability, and is easy to manufacture.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] 1. This rotary jet bag filter, during dust removal, when the high-pressure gas discharged through the pulse valve flows into the outlet pipe, it flows along the side wall of the drive fan blade on the side wall of the support rod, allowing the drive fan blade to rotate. The drive fan blade, through the cooperation of the support rod, rotating disk, and rotating ring, causes the rotating disk to start rotating. The high-pressure gas discharged from the outlet hole on the surface of the rotating disk rotates and sprays towards the filter bag located below the outlet pipe, so that the jet airflow dynamically surrounds and sprays towards the filter bag. The jet airflow covers the entire circumference of the filter bag with the rotation trajectory, avoiding blind spots, improving cleaning efficiency, and is simple and fast.

When cleaning is performed, the high-pressure gas discharged through the pulse valve 5 flows into the air outlet pipe 4 and flows along the side wall of the drive fan blades 10 on the side wall of the support rod 9, so that the drive fan blades 10 can rotate. The drive fan blades 10, through the cooperation of the support rod 9, the rotating disk 7 and the rotating ring 6, make the rotating disk 7 start to rotate. The high-pressure gas discharged from the air outlet 8 on the surface of the rotating disk 7 will rotate and spray towards the filter bag 2 located below the air outlet pipe 4, so that the airflow dynamically surrounds and sprays towards the filter bag 2. The airflow covers the entire circumference of the filter bag 2 with the rotation trajectory, avoiding blind spots, improving cleaning efficiency, and making it simple and fast.
[0032] In this embodiment, a rupture cone 12 is fixedly connected to the top of the drive fan blade 10. By setting the rupture cone 12, when the high-pressure airflow flows into the interior of the air outlet pipe 4, the rupture cone 12 will break the airflow, and the broken airflow will blow along the side wall of the rupture cone 12 to the drive fan blade 10 below, which will facilitate the rotation of the drive fan blade 10.
