Description

A bag dust collector that is easy to clean

Technical Field

The utility model relates to the technical field of bag dust collectors, in particular to a bag dust collector which is easy to clean.

Background Art

Bag filter is a dry dust filtering device that uses the filtering effect of fiber fabric to filter dust-containing gas. When the dust-containing gas enters the bag filter, the dust with large particles and high specific gravity settles down due to gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified. Bag filter has high dust removal efficiency, large air volume, simple operation, strong adaptability, and is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-containing gas.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

As shown in Figures 1 to 4, the utility model is a bag dust collector that is easy to clean, comprising: a dust collector 1, an ash hopper 4 arranged on the dust collector 1, a flower plate 5 fixedly connected to the dust collector 1, a filter bag 6 fixedly installed on the flower plate 5, a cleaning component 7 for cleaning the filter bag 6 and the ash hopper 4, an air inlet 2 and an air outlet 3 fixedly installed on the dust collector 1, turbid air to be filtered enters through the air inlet 2, is filtered by the filter bag 6 and then discharged through the air outlet 3, and the filtered dust falls into the ash hopper 4, and is then filtered. Centralized collection, the filter bag 6 is cleaned through a pulse valve, and the dust on the surface of the filter bag 6 falls down to avoid a decrease in the filtering effect of the filter bag 6. Then the surface of the filter bag 6 is cleaned again through the cleaning component 7 to avoid dust agglomeration on the surface of the filter bag 6, which affects the filtering effect of the filter bag 6. At the same time, the cleaning component 7 can also clean the surface of the ash hopper 4 to avoid dust agglomeration on the surface of the ash hopper 4, which makes it impossible to collect, causing the agglomerates to become larger, affecting the normal use of the dust collector 1, and the flower plate 5 is a support plate 79 for installing the filter bag 6.

The cleaning assembly 7 includes: a filter bag 6 cleaning assembly 7 for cleaning the filter bag 6, an ash hopper 4 cleaning assembly 7 for cleaning the surface of the ash hopper 4, and a driving assembly for driving the filter bag 6 cleaning assembly 7 and the ash hopper 4 cleaning assembly 7 to work.

The driving assembly includes: a driving motor 71 fixedly mounted on the dust collector 1 , and a threaded rod 72 fixedly connected to the driving motor 71 , and the threaded rod 72 is driven to rotate by the driving motor 71 .

The ash hopper 4 cleaning assembly 7 includes: a connecting shaft 78 fixedly installed at one end of a threaded rod 72, a support plate 79 fixedly connected to the connecting shaft 78, a fixed block 710 fixedly connected to the support plate 79, and a scraper 711 fixedly connected to the fixed block 710. When the threaded rod 72 rotates, the supporting plate 79 and the fixed block 710 are driven to rotate through the connecting shaft 78, so that the scraper 711 cyclically scrapes the surface of the ash hopper 4, thereby cleaning the agglomerated dust on the surface of the ash hopper 4, and two groups of scrapers 711 are provided, which can scrape the surface of the ash hopper 4 at a higher frequency, thereby improving the cleaning speed of the ash hopper 4.

The filter bag 6 cleaning assembly 7 includes: a connecting plate 75 threadedly connected to the threaded rod 72, a slider 74 fixedly connected to the connecting plate 75, the connecting plate 75 being slidably connected to the slide groove 73 through the slider 74, and the slide groove 73 is symmetrically arranged with the center line of the connecting plate 75. When the connecting plate 75 is lifted up and down, the slider 74 slides inside the slide groove 73, and the slide groove 73 limits the slider 74 to prevent the connecting plate 75 from shaking during the up and down lifting process. A cleaning brush 76 and a cleaning block 77 are fixedly mounted on the connecting plate 75. The cleaning brush 76 is sleeved on the surface of the filter bag 6. The cleaning block 77 is provided with two groups on the connecting plate 75. The inner wall of the cleaning brush 76 is installed with a bristle brush, which will not damage the bag material and can better remove dust and dirt. At the same time, when the connecting plate 75 is lifted up and down, the cleaning block 77 can sweep the dust inside the thread on the threaded rod 72 to avoid affecting the up and down lifting of the connecting plate 75, and the slide groove 73 is opened on the inner wall of the dust collector 1.

When the driving motor 71 drives the threaded rod 72 to rotate, the connecting plate 75 is connected to the threaded rod 72 through the threaded connection and the connection plate 75 is limited by the slider 74 and the slide groove 73, so that the rotational movement of the connecting plate 75 on the threaded rod 72 is converted into linear motion of the connecting plate 75. During the linear motion of the connecting plate 75, the cleaning brush 76 is driven to brush the surface of the filter bag 6. At the same time, the cleaning block 77 brushes the threaded rod 72 to prevent dust from being inside the thread and affecting the threaded connection between the connecting plate 75 and the thread, thereby completing the cleaning of the filter bag 6 and preventing dust from adhering to the surface of the filter bag 6 or dust caking, which affects the filtering effect of the filter bag 6.

Working principle:

The threaded rod 72 is driven to rotate by the driving motor 71. At this time, the connecting plate 75 is connected to the threaded rod 72 through the threaded connection and the connecting plate 75 is limited by the slider 74 and the slide groove 73, so that the rotational movement of the connecting plate 75 on the threaded rod 72 is converted into a linear motion of the connecting plate 75. During the linear motion of the connecting plate 75, the cleaning brush 76 is driven to brush the surface of the filter bag 6. At the same time, the cleaning block 77 brushes the threaded rod 72 to prevent dust from being inside the thread and affecting the threaded connection between the connecting plate 75 and the thread. At the same time, the connecting shaft 78 drives the support plate 79 and the fixed block 710 to rotate, so that the scraper 711 cyclically scrapes the surface of the ash hopper 4, thereby cleaning the agglomerated dust on the surface of the ash hopper 4. Two groups of scrapers 711 are provided, which can scrape the surface of the ash hopper 4 at a higher frequency.
