Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust collector technology, specifically to a dust collector with reverse blowing function. Background Technology
[0002] With increasingly stringent industrial environmental protection requirements, dust collectors, as key equipment in air pollution control, directly impact filtration efficiency and service life through their cleaning performance. Traditional dust collectors often employ a single reverse-air cleaning method, which suffers from the following technical drawbacks:
[0003] During the operation of a dust collector, dust will adhere to the surface of the filter element, forming a dust layer. Excessive accumulation will increase airflow resistance, affect the system air volume, and affect dust removal efficiency. Moreover, the dust removal process relies heavily on manual intervention, resulting in poor dust removal effect and low dust removal efficiency.
[0004] In summary, this utility model was developed to achieve simultaneous cleaning of the inside and outside of the filter element by optimizing the synergistic effect of airflow guidance and mechanical cleaning, thereby improving cleaning efficiency, reducing energy consumption and extending the service life of the filter element.

The top of the bidirectional lifting rod 5 is rotatably connected to the inner wall of the barrel 1.

[0031] Working principle:
[0032] When in use, the barrel 1 is fixed to the ground as the base of the whole equipment. First, start the fan 2. Under the operation of the fan 2, air pressure is formed inside. Then the gas will be drawn into the interior of the barrel 1 from the air inlet. After being purified by the filter element 9, the gas passes through the fan 2 and is discharged from the top air outlet pipe 4 of the fan 2.
[0033] When cleaning is required, motor 10 is turned on. The output end of motor 10 drives fixed gear 11, which in turn drives rotating gear 12. Rotating gear 12 drives bidirectional lifting rod 5 to rotate. Bidirectional lifting rod 5 drives lifting device 6 and back-blowing device 3 to move up and down synchronously. The connecting rod 61 on lifting device 6, driven by lifting block 31, drives movable rod 63 to move upward, opening the round cover 64 at the other end of movable rod 63 to allow airflow. At the same time as bidirectional lifting rod 5 is operating, the top tube 35 on back-blowing device 3, driven by lifting block 31, drives its sliding tube 3. 7 is inserted into the top air outlet pipe 4 of the barrel 1. The corrugated pipe 32 connected at the bottom expands synchronously during the rise, and the connecting pipe 36 connected at the bottom of the corrugated pipe 32 is inserted into the blocking plate 34. When the top pipe 35 connected at the top brings the gas into the pipe, the blocking plate 34 at the bottom simultaneously seals the filter element 9 in the fixed plate 7. At this time, the back-blowing airflow from the air outlet pipe 4 will push open the lower disc 344 in the blocking plate 34 along the inside of the pipe. Under the restriction of the limiting slide rod 342, the lower disc 344 reaches the designated position, so that the internal airflow is concentrated on the inside of the filter element 9, and effectively peels off the attached dust.
[0034] While the high-pressure airflow reverses and washes the inside of the filter element 9, the scraper discs 8 symmetrically arranged on the outer wall of the filter element 9 will simultaneously scrape the outer wall of the filter element 9 under the operation of the bidirectional lifting rod 5, achieving simultaneous cleaning inside and out, significantly improving dust removal efficiency, and further ensuring the long-term permeability of the filter element 9.
[0035] When cleaning is finished, simply reverse the output of motor 10. Under the rotation of motor 10, the bidirectional lifting rod 5 operates in the opposite direction, causing the sliding tube 37 in the back-blowing device 3 to retract, allowing the purified air to be discharged through the air outlet pipe 4. The bottom blocking plate 34 also moves upward. Without the pressure of the reverse airflow, the compression spring 343 at the bottom of the upper disc 341 will drive the lower disc 344 to reset, making it reach the closed state. The lifting device 6 also closes the round cover 64 under the rotation of the bidirectional lifting rod 5, making the interior airtight. At this time, turn off motor 10 to start dust removal.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
