Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and specifically, to a detection equipment for the production of dust removal filter bags. Background Art

[0002] The dust removal filter bag is a key part during the operation of a bag filter and is called the heart of the bag filter. The dust removal filter bag is the core component of the bag filter. A filter bag with good sealing performance can keep a stable air flow and pressure distribution inside the dust collector, and its sealing performance directly affects the dust removal effect. Therefore, during the production process of the dust removal filter bag, it is necessary to detect its sealing performance.

[0003] In the existing detection method, gas is usually introduced into the inside of the dust removal filter bag, and then it is observed whether there is gas leakage, so as to judge its sealing effect according to the change of its volume. However, if there are only very small holes on the surface of the dust removal filter bag, due to the slow air leakage rate, this detection method cannot immediately and intuitively judge the sealing performance of the dust removal filter bag and needs to wait for a period of time, thus reducing the detection efficiency.

[0004] In view of this, we propose a detection equipment for the production of dust removal filter bags. Summary of the Invention

The position of the pressing plate 352 is on the same side of the conveying chamber 1 as the receiving plate 15.

[0039] As Figures 7 - 8As shown in the figure, the detection device 4 includes a second motor 41. The output end of the second motor 41 is fixedly connected to a fourth threaded rod 411. A support frame 42 is arranged outside the fourth threaded rod 411. The second motor 41 is fixedly connected to one side of the support frame 42. A slide rail 421 is provided at the top of one side of the support frame 42. The fourth threaded rod 411 is located inside the slide rail 421. A sliding member 412 is threadedly connected to the outer wall of the fourth threaded rod 411. The sliding member 412 is slidably connected inside the slide rail 421. A first rotating rod 422 and a second rotating rod 423 are arranged inside the support frame 42. A circular gear 4222 is slidably connected to the outer wall of the first rotating rod 422. A strip-shaped protruding member 4221 is fixedly connected to the outer wall of the first rotating rod 422. A limiting member 413 is fixedly connected to the bottom of the sliding member 412. The limiting members 413 are distributed on both sides of the circular gear 4222. One end of the first rotating rod 422 is fixedly connected to a first soft roller 4223. A gear column 424 is fixedly connected to the outer wall of the second rotating rod 423. A second soft roller 425 is fixedly connected to the second rotating rod 423 on the same side as the first soft roller 4223.

The transmission belt 36 is sleeved on the outer wall of the first threaded rod 32 at the end far from the second rotating rod 423. The transmission belt 36 is located inside the transmission protection shell 23.

[0040] It can be seen from this that when it is necessary to sample and detect the inflated dust removal filter bag, as Figures 1 - 5 shown, when the staff puts the inflated dust removal filter bag into the feeding port 14. At this time, after the staff determines the material of the dust removal filter bag, they put it towards the position close to the first threaded rod 32. At this time, the first motor 31 drives the first threaded rod 32 to rotate, so that the push plate 321 on this side of the first threaded rod 32 pushes the inflated dust removal filter bag into the water tank 11 on the side of the receiving plate 15, and under the limitation of the pressing plate 352, it is detected whether there is air leakage. On the contrary, the inflated dust removal filter bag is pushed towards the position of the first soft roller 4223 and the second soft roller 425 by the other push plate 321 for extrusion detection, so as to perform different detection methods according to the material requirements of the inflated dust removal filter bag.

[0041] As Figures 4 - 5 shown, under the drive of the first motor 31, the first threaded rod 32 rotates and drives the push plate 321 on this side to slide. And the push plate 321 is a telescopic plate. The bottom of the push plate 321 will slide along the slope at the top of the detection chamber 2. After sliding to the topmost position of the detection chamber 2, it stops under the block of the limiting plate 33. At this time, the dust removal filter bag will slide down along the slope of the detection chamber 2 into the water on the side of the receiving plate 15 for detection. And the other push plate 321 will slide under the drive of the third motor 331 and the rotation of the second threaded rod 34, which is the same as the push plate 321 driven by the first threaded rod 32;

[0042] It should be noted that under the drive of the second motor 41, the fourth threaded rod 411 rotates. The fourth threaded rod 411 drives the sliding member 412 and the limiting member 413 to slide together. At this time, under the rotation of the first motor 31, the first threaded rod 32 drives the transmission belt 36, the second rotating rod 423, and the gear column 424 to rotate together. And at this time, the gear column 424 drives the circular gear 4222, the first rotating rod 422, and the first soft roller 4223 to rotate. At this time, the second soft roller 425 rotates in the opposite direction to the first soft roller 4223 to squeeze the inflated dust removal filter bag, and there is a staff member observing whether bubbles are generated to judge whether there is air leakage. By classifying and detecting dust removal filter bags of different materials, this enables preventing non-airtight packaging from being damaged by external forces through the different characteristics of the materials.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
