Problems solved by technology

[0003] However, in some larger pre-cyclone 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 airflow is released to the filter element, the filter element will deform and vibrate. In the process of shaking off the dust, the smaller the pulse air flow that the filter element is 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 the dust adhered to the surface of the filter element Falling down, which reduces the reusability of the filter element, and affects the next dust removal effect

Embodiment 1

[0036] Embodiment 1: a kind of bag filter of front cyclone dust collector, as figure 1 with 3 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 a blowing pipe 121 fixedly arranged on the top of the filter element 11a in the body 1, and the blowing pipe 121 is provided with an electromagnetic pulse valve 122. At this time, a plurality of filter elements 11a arrayed in a direction perpendicular to the blowing pipe 121 are defined. Form a group of filter components 11; in the body 1, there is an ash hopper 13 for dust storage under the filter element 11a, and there is a clean gas outlet 14 for clean gas discharge above the gas cleaning control system 12, and the ash hopper 13 The side wall of the ash hopper is p...

specific Embodiment approach

[0040] Specific implementation method: when the filter core 11a accumulates more dust near the middle and lower parts and cannot fall smoothly under the work of the dust removal control system 12, the driving motor 41 is controlled to work, the output shaft 411 rotates, and drives the circumference of the working rod 42 Rotate, when the working bar 42 rotates to conflict with the sliding working plate 33, it will drive the upward movement of the sliding working plate 33, because the width of the sliding working plate 33 is slightly longer than the connecting plate 31, so the working bar 42 and the sliding When the working plate 33 interferes, it will not interfere with the connecting plate 31; the sliding working plate 33 makes the telescopic spring 32 compressed during the upward sliding of the filter element 11a, because the working rod 42 moves away from it when it rotates with the output shaft 411. The running track of one end of the output shaft 411 is circular, so the end...

Embodiment 2

[0043] Embodiment 2: a kind of bag filter of front cyclone dust collector, the difference with embodiment 1 is, as Figure 4 with 5 As shown, the connecting plate 31 is provided with a limit mechanism 6 that controls the vertical vibration of the filter core 11a; the limit mechanism 6 includes an extension rod 61 that is fixedly arranged on the sliding work plate 33 and is perpendicular to it, and on the extension rod 61 A stop bar 62 perpendicular to it is fixedly provided, a stop slot 63 for the stop bar 62 to slide up and down is provided on the support plate 5, and a connection fixed to the support plate 5 is fixedly provided at the bottom of the extension bar 61 The spring 64, in order to prevent the limit rod 62 from sliding up and down in the limit groove 63, will conflict with the wall of the limit groove 63 and cause wear, so at this time, the outer circumferential surface of the limit rod 62 is wrapped with a protective cushion 621 .

Abstract

The invention discloses a bag-type dust collector with a prepositioned cyclone separator. The bag-type dust collector comprises a machine body, wherein a plurality of filter elements are arrayed in the machine body, a dust cleaning control system is arranged in the machine body located above the filter elements, the filter elements arrayed along the vertical direction of the dust cleaning controlsystem form a set of filter assembly, a dust hopper for storing dust is arranged in the machine body located below the filter elements, upper ends of the filter elements are fixedly connected with corrugated pipes separately, the ends, far away from the filter elements, of the corrugated pipes are fixedly connected with the dust cleaning control system separately, auxiliary vibration devices are separately arranged on the filter elements and comprise connecting plates arranged on external walls of the filter elements close to middle-lower parts, the connecting plates are fixedly connected witha set of filter assembly simultaneously, telescopic springs are fixedly arranged at bottoms of the connecting plates, the ends, far away from the connecting plates, of the telescopic springs are fixedly connected with slipping working plates, the slipping working plates are arranged on the external walls of the filter elements in a slipping manner and are located below the connecting plates, anda driving device for controlling the telescoping of the telescopic springs is arranged on the dust hopper.

Description

technical field [0001] The invention relates to air purification equipment, in particular to a bag dust collector with a pre-cyclone dust collector. Background technique [0002] The bag filter of the pre-cyclone dust collector 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; Composed of multiple filter elements, the gas enters the main body of the dust collector and passes 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; When a large amount of dust adheres to the filter element, through the dust removal control system, the compressed air is quickly opened and closed through the pulse valve, and the pulse air flow is released to enter the filter elem...
