Description

Technical Field

[0001] The utility model belongs to the technical field of pulse bag dust collectors, and in particular relates to a dust collecting device for pulse bag dust collectors. Background Art

[0002] The pulse bag dust collector is a high-efficiency industrial dust removal equipment, which is mainly used to capture, separate and remove dust and smoke generated in the industrial production process. At present, in order to centrally collect the dust filtered by the pulse bag dust collector, a special dust collection device for the pulse bag dust collector is usually used;

[0003] A dust collecting device for a bag dust collector with the authorization announcement number CN 219091411 U comprises an equipment base, an ash guide hopper and a telescopic channel, and a vibration device is arranged at the left side of the equipment base. The dust collecting device for a bag dust collector is provided with a vibration device, and dust falls into the inner cavity of the ash guide hopper through the telescopic channel with gravity, so that the overall weight of the ash guide hopper is increased, and four groups of springs are compressed to drive the stress block to move downward. When the controller senses that the stress block is close to the top position of the vibration column through the proximity sensor, the output end of the motor drives the vibration column to make repeated up and down movements under the limitation of the slider through the rotating disk and the rotating rod to impact the stress block, forcing the stress block to drive the ash guide hopper and the telescopic channel to vibrate, so that the dust attached to the inner cavity wall of the ash guide hopper and the telescopic channel falls and is discharged through the discharge port at the bottom side of the funnel end. Through the above operation, the automatic unloading function of the equipment is realized;

[0004] Although dust can be collected, there are still some problems in its use. The vibration cleaning method will cause the dust that has been effectively controlled to be re-suspended in the air under the action of vibration force during the dust removal process, thereby forming a secondary dust phenomenon. Secondly, the collected dust will be disturbed by the airflow, causing it to re-enter the dust collector circulation with the airflow. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a dust collection device for a pulse-type bag dust collector, including a dust collection funnel and a dust prevention mechanism arranged at the upper end of the dust collection funnel, the dust prevention mechanism including a rotating rod which is laterally symmetrically rotatably connected to the left and right ends between the front and rear walls of the dust collection funnel, the front and rear ends of the rotating rod respectively pass through the openings corresponding to the front and rear surfaces of the dust collection funnel and extend to the outside, a baffle is provided in the middle of the outer arc surface of the rotating rod, the two baffles are arranged in cooperation with each other, a worm gear is provided at the front extending end of the rotating rod, a mounting plate is provided at the upper end of the front surface of the dust collection funnel, a rotating rod is rotatably connected in a rotating hole arranged in the middle of the mounting plate, a worm gear is provided at the left and right ends of the rotating rod, the worm gears are respectively meshed with the adjacent worm gears on the same side, and a cleaning component for cleaning the baffle is also provided on the left and right sides of the upper end of the dust collection funnel.

[0007] The dustproof mechanism also includes a motor arranged on the front side of the upper end of the left surface of the dust collecting funnel, the right end of the output shaft of the motor is fixedly connected to the left end of the worm on the left side, and the motor is electrically connected to the external single chip computer.

[0008] The cleaning component includes an assembly opening which is laterally symmetrically arranged in the middle of the left and right sides of the upper end of the dust collecting funnel, and an electric telescopic rod is arranged in the assembly opening. The inner end of the telescopic end of the electric telescopic rod is provided with a fixed scraper, and the sliding scraper is vertically slidably connected in the slide groove arranged on the lower surface of the fixed scraper. The electric telescopic rod is electrically connected to an external single-chip computer, and the upper ends of the left and right walls of the dust collecting funnel are provided with accommodating grooves adapted to the fixed scraper; the cleaning component also includes grooves respectively arranged on the upper surfaces of the sliding scrapers, and longitudinally evenly distributed springs are arranged between the bottom wall of the groove and the top wall of the vertically adjacent slide groove.

[0009] The front and rear ends of the outer surface of the fixed scraper are both provided with longitudinally symmetrically distributed guide slide bars, and the upper sides of the front and rear ends of the left and right surfaces of the dust collecting funnel are both provided with guide holes corresponding to the guide slide bars.

[0010] A protective cover is arranged on the upper end of the front surface of the dust collecting funnel, and the mounting plate, the rotating rod and the worm are all located inside the protective cover.

[0012] The beneficial effects of the above technical solution of the utility model are as follows:

[0013] 1. First, the relevant staff fixed the dust collection funnel and its accessories to the lower part of the pulse bag dust collector through the mounting hole. When the pulse bag dust collector performs pulse dust removal, the dust is gradually deposited in the dust collection funnel in the funnel under the action of gravity. After the dust removal is completed, the external single-chip microcomputer controls the operation of the motor. The motor output shaft rotates to drive the worm on the left to rotate synchronously. When the worm on the left rotates, it drives the worm on the right to rotate synchronously through the rotating rod. Since the two worms are arranged symmetrically, when the two worms rotate synchronously, they drive the rotating rod through the worm gear meshing with it and the baffle on it to rotate in the opposite direction and close synchronously, thereby sealing the lower end of the dust collection funnel, effectively preventing dust from escaping upward during the operation of the equipment, preventing the phenomenon of secondary dust, and avoiding the problem that the collected dust is disturbed by the circulating airflow in the pulse bag dust collector and enters the dust collector again with the airflow for circulation.

[0014] 2. When it is necessary to clean the accumulated dust on the baffle, just open the baffle, and the external single-chip microcomputer controls the operation of the electric telescopic rod. The electric telescopic rod pushes the fixed scraper and its auxiliary mechanism to move inward. At the same time, the sliding scraper is always close to the surface of the baffle under the elastic action of the spring, thereby cleaning the dust on the surface of the baffle. When the fixed scraper moves, the guide slide bar ensures that the fixed scraper cleans the baffle stably and accurately. The cleaned dust falls into the dust collection funnel and waits for subsequent processing.

When the pulse bag dust collector performs pulse dust removal, the dust is gradually deposited in the dust collection funnel 100 in the funnel under the action of gravity.

At the same time, the sliding scraper 302 is always close to the surface of the baffle 201 under the elastic action of the spring 304, thereby realizing the cleaning of the dust on the surface of the baffle 201. When the fixed scraper 301 moves, the guide slide bar 400 ensures that the fixed scraper 301 stably and accurately cleans the baffle 201, and the cleaned dust falls into the dust collection funnel 100 and waits for subsequent processing.
