Description

Technical Field

[0001] The utility model relates to the technical field of bag-type dust removal equipment, in particular to a bag-type dust removal equipment. Background Art

[0002] The dust emitted during the production process of refractory materials is mechanically dispersed dust. Its properties and hazards are mainly determined by the chemical composition and particle size of the raw materials. These dusts are extremely harmful to the human body. Therefore, corresponding dust removal measures must be taken to improve them. The commonly used method is to use bag dust removal equipment to screen and remove dust. In the existing technology, when the bag dust removal equipment is used, the dust-laden gas enters from the air inlet. When passing through the ash hopper, some large dust particles in the gas are separated by inertia and fall directly into the ash hopper. Some particles can be separated from the airflow in advance, thereby improving the filtration efficiency. However, due to the influence of the airflow, there are still more large particles that flow upward under the drive of the airflow, and less dust is retained, resulting in an increase in the dust accumulation rate on the surface of the dust bag, an increase in the cleaning frequency, and affecting work efficiency.

[0022] Interception mechanism 4: It includes a windshield 41, a rotating column 42 and a filter plate 43. The windshield 41 is arranged between the left and right inner walls of the dust removal housing 1. The inclined plate of the windshield 41 corresponds to the horizontal position of the air inlet pipe 2. The rotating column 42 is rotatably connected between the front and rear inner walls of the dust removal housing 1. The outer arc surface of the rotating column 42 is respectively provided with a filter plate 43. The filter plate 43 located on the upper side of the rotating column 42 corresponds to the horizontal position of the air inlet pipe 2. When the dust enters the interior of the dust removal housing 1, the dust will hit the inclined plate surface of the windshield 41 under the action of the airflow. Under the guidance of the filter, some large particles of dust are passively separated from the air flow and fall downward. At the same time, the rotating column 42 drives the filter plate 43 to rotate clockwise, and the dust in the air flow is filtered through the filter plate 43, while the filtered dust is driven downward, actively separating the dust from the air flow and falling downward. By actively and passively coordinating, the dust is more comprehensively intercepted. The interception mechanism 4 also includes a scraper 44 and a slide column 45. The slide column 45 is respectively slidably connected to the slide hole on the surface of the dust removal shell 1. There is a scraper provided between the ends of the slide column 45. The plate 44, the scraper 44 and the filter plate 43 are installed in cooperation. The interception mechanism 4 also includes a tension spring 46. The tension spring 46 is respectively arranged between the limit plate at the end of the slide post 45 and the surface of the dust removal shell 1. The tension spring 46 is movably sleeved on the outer arc surface of the slide post 45. During the rotation of the filter plate 43, when the filter plate 43 contacts the scraper 44, the filter plate 43 applies a force to the scraper 44, pushing the slide post 45 to slide, and using the scraper 44 to push and scrape the surface of the filter plate 43, so that the filtered dust leaves the surface of the filter plate 43, and at the same time the tension spring 46 stretches Generate elastic force. When the filter plate 43 is separated from the scraper 44, the scraper 44 is reset under the elastic force of the tension spring 46. The upper surface of the wind shield 41 is provided with an inclined plate 5. The upper surface of the inclined plate 5 gradually tilts downward from the center to the front and rear ends, reducing the accumulation of dust on the upper surface of the wind shield 41. The interception mechanism 4 also includes a motor 47. The motor 47 is arranged at the front end of the dust removal shell 1. The output shaft of the motor 47 is fixedly connected to the front end of the rotating column 42. The input end of the motor 47 is electrically connected to the output end of the single-chip microcomputer 9 to provide power for the rotation of the rotating column 42.

[0023] The working principle of the bag dust removal equipment provided by the utility model is as follows: during the refractory material processing, the dust generated during the refractory material crushing process will enter the dust removal shell 1 together with the air flow through the air inlet pipe 2, and the dust will hit the inclined plate surface of the wind shield 41. Under the guidance of the inclined plate of the wind shield 41, some large particles of dust are passively separated from the air flow and fall downward. At the same time, the motor 47 is started by the single-chip microcomputer 9, and the output shaft of the motor 47 drives the rotating column 42 and the filter plate 43 to rotate clockwise, and the dust in the air flow is filtered by the filter plate 43, and at the same time, the filtered dust is driven to move downward, actively separating the dust from the air flow and falling downward. By combining active capture and passive guidance, the dust is more comprehensively intercepted. The intercepted dust will move upward with the air flow, and the dust in the air flow is filtered by the filter bag 7, and the filtered air is discharged from the outlet pipe 3.

[0024] It is worth noting that the microcontroller 9 disclosed in the above embodiment can be a PIC16F1823-I / P model microcontroller, and the motor 47 can be freely configured according to the actual application scenario. It is recommended to use a D08LD40-48A-30S model motor. The microcontroller 9 controls the operation of the motor 47 using methods commonly used in the prior art.
