Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, and more specifically, to a filter element of a soot purification device. Background Technique

[0002] Soot mainly comes from processes such as welding, cutting, and grinding in industrial production, as well as operations such as excavation and mixing in construction. These soot contain a large amount of particulate matter, harmful gases, and microorganisms, posing a serious threat to the environment and human health. Long-term inhalation of this soot may lead to health problems such as respiratory diseases and cardiovascular diseases, and at the same time, it will also pollute the surrounding environment.

[0003] Therefore, it is necessary to be equipped with a special filtering mechanism to filter the soot to ensure the quality of the discharged gas. The existing filter element has a simple structure. During use, dust will block the outside of the filter cylinder. As the use time increases, the filtering efficiency will decrease, affecting the use. In view of this, we propose a filter element of a soot purification device. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a filter element of a soot purification device to solve the technical problem that the current filtering mechanism is easy to be blocked, affecting the filtering quality during long-term use.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A filter element of a soot purification device, including a filter element housing and a driving mechanism. An exhaust seat is provided at the bottom of the filter element housing. Upper and lower sleeves are respectively provided at the upper and lower ends inside the filter element housing, and the upper and lower sleeves are connected by a connecting rod. The lower sleeve is located between two driving mechanisms. A filter cylinder is inserted inside the filter element housing, and the lower end of the filter cylinder is butted against the exhaust seat. A top cover is fixed at the upper end of the filter cylinder, and the top cover fits the upper end opening of the filter element housing. There are two driving mechanisms in total, and the two driving mechanisms are respectively embedded and installed on both sides of the lower end of the filter element housing.

[0006] When the utility model is in use, it is powered by an external power supply. The motor in the driving mechanism is started through an external control device to drive the driving gear to rotate. The driving gear meshes with the toothed ring to drive the turntable to rotate. The turntable drives the pressure rod to deflect. The pressure rod biases and extrudes the tapered port to drive the lower sleeve to complete self-rotation and lifting. The lower sleeve drives the upper sleeve synchronously. The annular brushes inside the upper and lower sleeves clean the dust on the outside of the filter cylinder. After scraping, the dust falls into the dust collection groove at the bottom. The outside of the filter cylinder is cleaned through the above-mentioned annular brush, avoiding dust blockage caused by long-term use and affecting the subsequent filtering quality. The walking design of self-rotation and lifting ensures the quality of scraping dust.

[0007] Preferably, air vent holes are annularly arrayed on the outer sides of the upper sleeve and the lower sleeve, and annular brushes are equidistantly distributed on the inner sides of the upper sleeve and the lower sleeve.

[0008] Preferably, the driving mechanism is composed of an embedding shell, a turntable and a pressing rod. The turntable is rotatably installed in the embedding shell, and the pressing rod is fixed to the side of the turntable.

[0009] Preferably, a driving gear is rotatably installed on one side inside the embedding shell. A toothed ring is sleeved and fixed on the outer side of the outer end of the turntable, and the driving gear is meshed with the toothed ring.

[0010] Preferably, a tapered opening is formed on the outer side of the lower sleeve, and the tapered opening is distributed in a staggered manner with the air vent holes.

[0011] Preferably, the tapered opening is designed as an annular curved groove, and the outer end of the pressing rod is inserted and matched with the tapered opening.

[0012] Preferably, a dust collecting groove is formed at the inner bottom end of the filter element shell, and the dust collecting groove corresponds to the upper sleeve and the lower sleeve.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By designing the annular brush, the present utility model starts the motor in the driving mechanism to drive the driving gear to rotate. The driving gear meshes with the toothed ring to drive the turntable to rotate. The turntable drives the pressing rod to deflect. The pressing rod biases and squeezes the tapered opening to drive the lower sleeve to complete self-rotation and lifting. The lower sleeve drives the upper sleeve synchronously. The annular brushes on the inner sides of the upper sleeve and the lower sleeve clean the dust on the outer side of the filter cartridge. After scraping, the dust falls into the dust collecting groove at the bottom. Through the above-mentioned annular brush, the outer side of the filter cartridge is cleaned, avoiding dust blockage caused by long-term use and affecting the subsequent filtration quality. The walking design of self-rotation and lifting ensures the quality of scraping dust.

[0015] 2. By designing the upper sleeve and the lower sleeve, the driving mode of the driving mechanism makes the stroke height of the cleaning mechanism shorter. A single cleaning mechanism cannot effectively clean in all directions. The upper sleeve and the lower sleeve divide the surface of the filter cartridge into corresponding four cleaning areas. The upper sleeve and the lower sleeve are responsible for two corresponding areas. While cleaning in all directions, it avoids the blockage of internal air flow caused by excessive shielding area and affects filtration. BRIEF DESCRIPTION OF THE DRAWINGS

The design of the air passage holes 603 reduces the shielding surface and the resistance during the flow of the air flow. Annular brushes 602 are equally spaced on the inner sides of the upper casing 5 and the lower casing 6. The lower casing 6 is located between two driving mechanisms 3. A filter cartridge 7 is inserted into the inner side of the filter element housing 2, and the lower end of the filter cartridge 7 is butted against the exhaust seat 4. The gas filtered by the filter cartridge 7 is discharged through the exhaust seat 4 at the bottom.

The turntable 302 is driven to rotate by the cooperation of the driving gear 303 and the toothed ring 304. A tapered opening 601 is provided on the outer side of the lower sleeve 6, and the tapered opening 601 is misaligned with the air passage hole 603. The tapered opening 601 is designed as an annular curved groove. The outer end of the pressing rod 305 is inserted and matched with the tapered opening 601. When the outer end of the pressing rod 305 travels in the tapered opening 601 during deflection, combined with the structural design of the tapered opening 601, the lower sleeve 6 is rotated and lifted. A dust collection groove 201 is provided at the inner bottom end of the filter element housing 2, and the dust collection groove 201 corresponds to the upper sleeve 5 and the lower sleeve 6. The scraped dust is collected through the dust collection groove 201, which is convenient for later disassembly and cleaning.

[0025] Working principle: This embodiment provides a filter element of a smoke and dust purification device. When in use, it is powered by an external power supply, and the motor in the driving mechanism 3 is started through an external control device to drive the driving gear 303 to rotate.
