Description

Technical Field

[0001] The present invention relates to the technical field of dust collectors, in particular to a novel filter element self-cleaning technology and a dust collector thereof. Background Art

[0002] A dust collector is a device used to remove suspended particulate matter from the air. It is widely used in industries such as industry, mining, construction, and environmental protection. Its primary function is to capture and filter dust, smoke, particulate matter, and pollutants from the air through physical or chemical methods, thereby improving air quality, protecting the environment, and reducing harm to human health. Dust collectors are generally classified into various types based on their operating principles, such as bag filters, electrostatic precipitators, and scrubbers. Bag filters utilize the fabric of the filter bags to capture dust through physical filtration, while electrostatic precipitators utilize an electric field to charge particulate matter, which then attracts it to electrodes. By using dust collectors, companies can not only meet national and local environmental regulations but also improve the safety and comfort of the working environment, thereby enhancing production efficiency and employee health.

[0003] In the prior art, such as Figure 4 As shown in the left picture, the upper part of the filter element is the dust accumulation area, and it can be clearly seen that the lower part of the filter element is almost idle and unused. The filter element is inefficient. In addition, due to the small air volume of the traditional dust cleaning spray design, the dust accumulated locally on the filter element after the spray cleaning is often not effectively and thoroughly removed, and there will always be residues left, which is detrimental to the efficiency and life of the filter element. Figure 4 As shown in the right figure, the traditional dust collector design has a single internal air duct path, and the inhaled air directly hits the front filter element, resulting in a high utilization rate of the front filter element and a low utilization rate of the rear filter element. Dust is often only enriched on the front filter element, and the rear filter element has less dust enrichment. In addition, this design does not protect the filter element, resulting in an unreasonable internal air duct and a lack of protection measures for the filter element. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides a novel filter element self-cleaning technology and a dust collector thereof, which solves the problem of low dust removal efficiency of the filter element.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a novel filter element self-cleaning technology and a dust collector thereof, comprising a dust collector frame, wherein a plurality of blowing pipes are fixedly provided at the upper end of the interior of the dust collector frame, one end of each of the blowing pipes is connected to an air bag via an electromagnetic pulse valve, and the lower ends of each of the blowing pipes are provided with a plurality of blowing ports, and the lower ends of each of the blowing ports are fixedly connected to a venturi tube;

[0006] A plurality of filter elements are fixedly installed inside the dust collector frame, and an inner liner is fixedly sleeved at the upper end of each filter element. An air duct opening is opened on one side of the dust collector frame, and a louver steel baffle is fixedly installed near the air duct opening inside the dust collector frame.

[0007] Preferably, the lower end of the air bag is fixedly arranged inside the dust collector frame.

[0008] Preferably, support legs are fixedly provided at the four corners of the lower end surface of the dust collector frame, and reinforcing rods are fixedly provided between each of the four support legs.

[0009] Preferably, an ash hopper is fixedly provided at the center of the lower end surface of the dust collector frame.

[0010] Preferably, an ash discharge mechanism is fixedly provided at the lower end of the ash hopper, and a plurality of moving wheels are fixedly provided at the lower end of the ash discharge mechanism.

[0011] Preferably, the number of the plurality of filter elements is the same as the number of the venturi tubes, and each venturi tube is located at the upper end of the filter element.

[0012] The present invention provides a novel filter element self-cleaning technology and a dust collector thereof. It has the following beneficial effects:

[0013] The present invention provides a novel filter element self-cleaning technology and a dust collector thereof. The dust collector provided by the present invention has an inner lining added to each filter element. The dust-enriched area on a single filter element extends from the middle of the filter element to both sides, and the usable area of ​​the filter element is greatly improved, thereby improving the use efficiency of a single filter element and making it easier to remove dust accumulated on the filter element. At the same time, a venturi tube is added to the nozzle, and the Venturi effect is utilized to increase the amount of gas blown for cleaning. In combination with the above-mentioned inner lining, the cleaning efficiency of a single filter element is improved. By adding a louver steel baffle in the dust collector, the air duct flows more evenly to all filter elements, thereby increasing the overall filtration efficiency of the dust collector and the efficiency of filter element use.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-8 As shown, the embodiment of the present invention provides a novel filter element self-cleaning technology and a dust collector thereof, comprising a dust collector frame 1, wherein a plurality of blowing pipes 8 are fixedly provided at the upper end of the interior of the dust collector frame 1, one end of the plurality of blowing pipes 8 is connected to an air bag 7 via an electromagnetic pulse valve 13, and the lower ends of the plurality of blowing pipes 8 are each provided with a plurality of blowing ports, and the lower ends of the plurality of blowing ports are each fixedly connected to a venturi tube 9;

[0025] A plurality of filter elements 2 are fixedly installed inside the dust collector frame 1, and an inner lining 6 is fixedly sleeved at the upper end of the filter element 2. An air duct opening 10 is opened on one side of the dust collector frame 1, and a louver steel baffle 11 is fixedly installed near the air duct opening 10 inside the dust collector frame 1.

[0026] The lower end of the air bag 7 is fixedly mounted within the dust collector frame 1. Support legs 4 are fixedly mounted at the four corners of the lower end surface of the dust collector frame 1, with reinforcement rods 12 fixedly mounted between each pair of support legs 4. An ash hopper 3 is fixedly mounted at the center of the lower end surface of the dust collector frame 1. An ash discharge mechanism 14 is fixedly mounted at the lower end of the ash hopper 3, and multiple moving wheels 5 are fixedly mounted at the lower end of the ash discharge mechanism 14. The number of filter elements 2 is the same as the number of venturi tubes 9, and each venturi tube 9 is located at the upper end of the filter element 2.

[0027] The innovative design of the dust collector of this invention solves several problems existing in traditional dust collectors, improving overall efficiency and effectiveness. First, an inner lining 6 is added to each filter element 2, expanding the dust accumulation area from the center to both sides. This design significantly increases the usable area of ​​the filter element, improving dust collection efficiency and facilitating thorough cleaning of accumulated dust, thereby extending the filter element's service life.

[0028] Secondly, by installing a venturi tube 9 at the injection port, the Venturi effect is utilized to increase the amount of gas injected for cleaning. This not only enhances the cleaning capacity but also achieves a more thorough removal of accumulated dust through more efficient airflow coverage. This, combined with the design of the liner 6, significantly improves the cleaning efficiency of a single filter element.

[0029] Furthermore, the internal structure of the dust collector has been optimized, with the addition of a steel shutter 11, which allows for more even distribution of airflow across all filter elements. This design overcomes the single airflow path and uneven airflow issues found in traditional dust collectors, preventing dust from confining to the front row of filters while leaving the rear row unused, and significantly improving overall filter efficiency.

[0030] Overall, these improvements not only enhance the dust collector's filtration efficiency but also promote uniform utilization and protection of the filter element, improving system stability and efficiency, meeting increasingly stringent environmental protection requirements, and reducing maintenance costs and frequency. Through these technical measures, the dust collector provided by the present invention achieves significant improvements in both performance and economic efficiency.

[0031] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
