DETAILED DESCRIPTION

[0024] The two embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0025] First embodiment:

[0026] Figures 1-5 A high-wind-pressure dust collector is shown, which comprises an equipment outer cavity 1, the inner end of the equipment outer cavity 1 is provided with an internal partition plate 3, the lower end of the internal partition plate 3 is fixedly connected with a plurality of electric push rods 4 distributed in a rectangular shape, the output ends of the plurality of electric push rods 4 are connected with a plurality of fixedly connected displacement hollow outer rings 5 fixedly connected with each other, the inner end of the internal partition plate 3 is fixedly connected with a plurality of filter cartridges 7, the upper end of the internal partition plate 3 is fixedly connected with a backflush pump 8 on the front side, the output end of the backflush pump 8 is also fixedly connected with a plurality of backflush pipelines 9, the output ends of the plurality of backflush pipelines 9 respectively extend into the corresponding filter cartridges 7, the inner end of the equipment outer cavity 1 is provided with a pump 6 on the upper side, the inner side wall of the displacement hollow outer ring 5 is fixedly connected with a plurality of annular elastic connecting pieces 11 arranged at equal intervals, one end of the elastic connecting piece 11 away from the displacement hollow outer ring 5 is fixedly connected with an arc unit block 12, the inner side wall of the displacement hollow outer ring 5 is fixedly connected with a plurality of groups of connecting columns 13, and one group of connecting columns 13 is located on both sides of the corresponding elastic connecting piece 11, one end of the connecting column 13 close to the arc unit block 12 is fixedly connected with a pressure sensor 14.

[0027] Figures 1-5 The left end of the equipment outer cavity 1 is fixedly connected with a dust collecting pipeline 10, the plurality of displacement hollow outer rings 5 are respectively located on the outer side positions of the corresponding filter cartridges 7, the arc unit block 12 and the pressure sensor 14 cooperate with each other, and the front end of the equipment outer cavity 1 is fixedly connected with a control panel 15 on the upper side.

[0028] Figures 1-5The dust-containing air enters the device through the dust collection pipe 10 fixedly connected to the left end of the outer cavity 1 of the device. The pump 6 in the outer cavity 1 of the device operates to generate suction force to promote the flow of dust-containing air. The dust-containing air passes through the internal partition 3 under the action of the suction force of the pump 6. At this time, the filter element 7 starts to play a filtering role to intercept dust particles in the air. The purified air is discharged from the outer cavity 1 of the device. After the filter element 7 is used for a period of time, it needs to be cleaned to ensure its filtering effect. At this time, the backflush pump 8 fixedly connected to the front side of the upper end of the internal partition 3 is started. The output end of the backflush pump 8 is connected with a plurality of backflush pipes 9. The output ends of the backflush pipes 9 respectively extend into the corresponding filter elements 7. The backflush pump 8 generates a reverse airflow which enters the filter element 7 through the backflush pipe 9 to blow off the dust attached to the filter element 7, completes the reverse cleaning, and makes the inside and outside of the filter element 7 unblocked. After the filter element 7 completes the reverse cleaning, the clogging detection stage is entered. The plurality of displacement hollow outer rings 5 slide up and down outside the filter element 7 through the electric push rod 4. The electric push rod 4 is started to push the displacement hollow outer ring 5 to slowly move downward along the axial direction of the filter element 7. At the same time, the backflush pump 8 is started again. In the normal state of the filter element 7, the air outlet pressure is relatively stable and uniform. However, when the filter element 7 has a clogging position, the air flow at this position is blocked, and the air outlet pressure will change obviously. This pressure change will cause the arc unit block 12 in the displacement hollow outer ring 5 to be blown to different degrees. When the arc unit block 12 is blown due to the pressure change, the pressure data of the pressure sensor 14 in contact with the arc unit block 12 will be inconsistent. The control panel 15 collects the data transmitted by each pressure sensor 14 in real time. Once the pressure data is detected to fluctuate abnormally, it is judged that the filter element 7 has a clogging condition, and a prompt signal is immediately sent to the worker. The plurality of displacement hollow outer rings 5 work cooperatively to form a multi-point detection network, which greatly improves the accuracy of detecting the clogging state of the filter element and can monitor the running condition of the filter element 7 in real time to effectively avoid the decrease of the working efficiency of the device due to the clogging of the filter element.
