Problems solved by technology

[0003] However, in some larger bag filters, the filter element is set longer, and the dust removal control system is generally set on the top of the filter assembly. When the pulse air flow is released to the filter element to deform and vibrate the filter element, it is easy to shake off the dust. During the process, the smaller the pulse air flow that the filter element is exposed to away from the dust removal control system, the smaller the vibration and deformation of the filter element away from the dust removal control system, which is not enough to shake off the dust adhering to the surface of the filter element, thereby reducing the dust loss. The reusability of the filter element affects the next dust removal effect

Embodiment 1

[0034] Embodiment 1: a kind of vibration device used in the bag filter, such as figure 1 Shown, mainly comprises body 1, is provided with a plurality of filter elements 11a in body 1, and filter element 11a is arranged in the body 1 in row-and-column array, is positioned at the top of filter element 11a in body 1 and is provided with cleaning control system 12, cleaning The control system 12 mainly includes an injection pipe 121 fixedly arranged in the body 1 above the filter element 11a. The injection pipe 121 is provided with an electromagnetic pulse valve 122. At this time, a plurality of filter elements 11a arrayed along the horizontal direction of the injection pipe 121 are defined to form a Group filter assembly 11; in the body 1, below the filter element 11a, there is an ash hopper 13 for dust storage. In the gas, there is a clean gas outlet 14 for clean gas discharge above the dust removal control system 12. The side of the ash hopper 13 The wall is provided with a dus...

specific Embodiment approach

[0037]Specific implementation method: when the filter core 11a accumulates a lot of dust near the middle and lower parts and cannot fall smoothly under the work of the dust removal control system 12, the drive motor 41 is controlled to work, the output shaft 42 rotates, and drives the connecting disc 43 Circumferential rotation, now can drive the movement of the connecting rod 44 hinged with the connecting disc 43, that is, one end of the connecting rod 44 hinged with the connecting disc 43 moves in a circle along with the connecting disc 43, because the impact body 2 is located in the impact sleeve 31, the restricting effect on the connecting rod 44 can be achieved, that is, the range of motion of the connecting rod 44 is limited, so that the end of the connecting rod 44 away from the connecting disc 43 can only swing in a small range. When swinging, it can drive the swing of a plurality of fixed rods 3 connected thereto, so that the inner wall of the impact sleeve 31 collides...

Embodiment 2

[0040] Embodiment 2: a kind of vibration device used in the bag filter, the difference from embodiment 1 is, as Figure 4 and 5 As shown, at this time, the strut 21 of the impact body 2 is hingedly arranged at the bottom of the filter core 11a, and an electromagnet 311 controlled by a circuit signal is provided in the impact sleeve 31, and the electromagnet 311 can realize the adsorption of the impact body 2 effect.

[0041] When the staff checks that there is only a large amount of dust accumulated on the individual filter elements 11a in the dust collector, they can control the electromagnet 311 in the sleeve 31 at the bottom of the corresponding filter element 11a to make it energized, and the electromagnet 311 After being energized, the impact body 2 will be adsorbed, so that the impact body 2 swings until it is attracted to the electromagnet 311, and then the electromagnet 311 is controlled to lose power. At this time, after losing the suction force of the electromagnet ...

Abstract

The invention discloses a vibration device for a bag-type dust collector. The vibration device comprises a machine body, wherein a plurality of filter elements are arrayed in the machine body, a dustcleaning control system is arranged in the machine body located above the filter elements, a dust hopper for storing dust is arranged in the machine body located below the filter elements, impact bodies are fixedly arranged at bottoms of the filter elements separately, fixing rods are separately arranged in the machine body located below the filter elements, impact sleeves for encircling the impact bodies are separately arranged at the ends, close to the filter elements, of the fixing rods, a plurality of driving devices for controlling the sloshing of the fixing rods are arranged at internalpositions, close to the fixing rods, of the machine body and comprise a plurality of driving motors fixedly arranged in the machine body, connecting discs are fixedly arranged on output shafts of thedriving motors, connecting levers are hinged to parts, far away from centers of circle, of the connecting discs, and the ends, far away from the connecting discs, of the connecting levers are vertically fixed to the fixing rods separately. According to the bag-type dust collector, through a simple structure, dust of positions, far away from the dust cleaning control system, of the filter elementscan be successfully cleared out.

Description

technical field [0001] The invention relates to air purification equipment, in particular to a vibration device used in a bag filter. Background technique [0002] The bag filter is a dry dust filter device, which is suitable for collecting fine, dry, non-fibrous dust. It is generally composed of a dust collector host, a filter assembly and a dust removal control system; Enter the main body of the dust collector and pass through the filter element. At this time, the dust impurities in the gas adhere to the filter element, and the gas passes through the filter element to become clean gas and then is discharged, thus realizing the filtering of the gas; After a large amount of dust, the compressed air is released through the dust removal control system, that is, the pulse valve is quickly opened and closed, and the pulse air flow is released into the filter element. The deformation and vibration of the filter element shake off the dust adhered to the surface of the filter eleme...
