Description

Technical Field

[0001] This application relates to the field of dust removal, specifically to a dust collector that is easy to operate and maintain. Background Technology

[0002] Dust collectors are commonly used environmental protection dust removal equipment in industry. In many cases, industrial exhaust gases often contain a large amount of dust, requiring multiple environmental treatment steps such as dust removal, desulfurization, and denitrification before emission. Therefore, the use of dust collectors is essential. Dust collectors can filter dust from flue gas using dust collection filter bags. Since the dust removal efficiency is related to the number of filter bags and the dust removal capacity of each bag, the required number of dust collection filter bags can be calculated based on the required flue gas flow rate to meet the dust removal needs. The dust removal capacity of a single filter bag depends not only on the material of the filter bag but also on its surface area; a larger surface area results in better dust removal. However, because dust collection filter bags remove dust through filtration, the filter pores become clogged with dust after a period of use, necessitating cleaning. Otherwise, the dust removal efficiency of the filter bags will significantly decrease. However, existing dust collector filter bags often have a limited dust removal area due to the cage frame, and the cleaning operation is not intelligent enough. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the problems in the above-mentioned background technology and further improve the dust removal process to achieve better dust removal effect, this application provides a dust collector that is easy to operate and maintain.

[0026] Furthermore, it also includes a cylinder mounting bracket for mounting the lifting cylinder.

[0027] Therefore, during routine dust removal operations, the sliding seat can be moved to the dustproof position and covered by the dust cover, thus protecting the dust removal unit from dust contamination.

[0028] Furthermore, the bottom end of the filter bag body is fixedly connected to the bottom circular plate.

[0029] Beneficial effects: The dust collector of this application adopts a rectangular array distributed layout for multiple dust filter bags, so that one cleaning unit can clean two rows of dust filter bags, thereby saving the installation of cleaning units.

[0047] The dust collector of this application, as shown in the figure, uses a partition plate to separate the flue gas space and the clean space. It employs an internal filtration system; the air above containing flue gas passes through the internal filter, and the airflow below becomes clean. The dust particles fall into the filter bags. Because the cage is hinged, during dust removal... Figure 10 As shown, the filter bag is in a nearly taut state. During dust removal, the filter bag is... Figure 9 As shown, the filter bag has pleats, and because it is an internal filter, the airflow inside the filter bag blows it open, thus giving the filter bag a good filtration area and resulting in good dust removal effect.

[0048] Furthermore, because the dust removal unit is mounted on a sliding base and has a rotating plate with a rotary cylinder, one dust removal unit can work on two rows of dust filter bags. As shown in the figure, by raising and lowering the lifting base, the lifting base can be lowered to... Figure 3 At the desired position, the second electric push rod extends, causing the insert plate to disengage the locking rack from the drive gear, and the drive head abuts against the abutment block, thereby driving the drive gear to rotate, causing the lifting rack to rise to... Figure 5 When the position is reached, the first electric actuator extends, allowing the drive block to extend into the elliptical ring, and the second electric actuator shortens, as shown. Figure 6 As shown, the rotation of the first motor creates a cam-like effect, causing the vertical guide rod at the lifting rack to vibrate up and down. This rapidly shakes the filter bag body, dislodging the dust. At this point, the negative pressure suction unit is activated. The combined effect of shaking and negative pressure ensures rapid and effective dust removal from the filter bag. Furthermore, in dust removal mode, to enhance filter bag stability, the lifting rack can be lowered slightly, compressing the upper and lower springs. This further stabilizes the cage structure, enabling it to handle the corresponding dust collection airflow.
