Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a self-cleaning device for filter bags, particularly an automatic dust removal filter device. Background Technology

[0002] With the continuous advancement of industrialization, dust emissions from various industrial production processes have become increasingly serious. To effectively reduce industrial pollution, baghouse dust collectors are widely used in various production fields, such as coal, metallurgy, cement, and chemical industries. As a common dry dust filtration device, the baghouse dust collector primarily captures airborne dust through filter bags. In this process, when dust-laden gas enters the filter bags, larger dust particles are blocked, while smaller particles are retained on the surface of the filter bags, thus purifying the airflow. However, with prolonged use, the amount of dust retained on the surface of the filter bags increases, leading to a gradual decrease in the filtration efficiency of the baghouse dust collector, and potentially even causing filter bag clogging. This not only reduces the dust removal effect but may also increase energy consumption and even affect the normal operation of the equipment.

[0003] To maintain dust removal efficiency, filter bags typically require regular cleaning. However, traditional manual cleaning methods are time-consuming, labor-intensive, and inefficient. Therefore, developing a device that can automatically remove dust from filter bags is crucial for improving the efficiency of baghouse dust collectors, extending equipment lifespan, and reducing manual intervention. While existing automatic dust removal technologies include vibration cleaning and reverse air blowing, they still suffer from uneven cleaning results, complex equipment, and difficulty in precisely controlling the cleaning cycle.

Detailed Implementation

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] like Figures 1 to 2 As shown, the automatic dust removal filtration device includes a housing with an air inlet 1a, an air outlet 1b, and a dust discharge port 2a. An isolation component is provided between the air inlet 1a and the air outlet 1b inside the housing. Several filter components are provided on the isolation component. The filter components are connected to a clean airflow path from the air inlet 1a to the air outlet 1b. At least one vibrator 7 is provided on the isolation component. The isolation component is connected to the housing through an elastic component.

[0030] The chassis includes a cylindrical shell 1, an air inlet 1a is provided on the side wall of the shell 1, an air outlet 1b is provided on the top wall of the shell 1, a dust collection hopper 2 is connected to the bottom of the shell 1, the bottom opening of the dust collection hopper 2 is a dust discharge port 2a, and a dust collection box 3 is connected below the dust discharge port 2a.

[0031] Dust-laden gas enters the housing 1 through the air inlet 1a on the side wall, passes upward through the filter assembly to retain the dust, and the clean air passes through the filter and is discharged from the air outlet 1b on the top wall; the accumulated dust falls down and is collected in the dust collection box 3 from the dust discharge port 2a.

[0032] The isolation assembly includes a sealing plate 5, which is positioned above the air inlet 1a and below the air outlet 1b. The sealing plate 5 is arranged on the cross-section of the housing 1, and a flexible connection is formed between the outline of the sealing plate 5 and the inner wall of the housing 1 by an elastic ring 6. The specific material of the elastic ring 6 is selected according to the nature of the dust-laden airflow, and the material is required to be a flexible connection with elasticity, such as rubber.

[0033] The sealing plate 5 is a square plate, and the elastic ring 6 is a square-shaped sheet, which is fitted around the outer periphery of the sealing plate 5. The elastic ring 6 achieves both a sealed connection between the rigid sealing plate 5 and the housing 1, and allows the sealing plate 5 to move within a certain range due to its elasticity. Thus, the sealing plate 5 and the elastic ring 6 divide the cross-section of the housing 1 into upper and lower chambers, thereby preventing dust from entering the upper chamber and causing filtration failure.

[0034] The elastic ring 6 is fastened to the sealing plate 5 by several bolts, and the elastic ring 6 is fastened to the housing 1 by several bolts.

[0035] The elastic component includes several springs 4. One end of each spring 4 is connected to the top wall of the housing 1, and the other end of each spring 4 is connected to the sealing plate 5. A total of four springs 4 are provided, arranged in a square matrix. The sealing plate 5 is elastically suspended below the air outlet 1b by the four springs 4, and the elastic force of the springs 4 provides a buffering effect for the vibration of the sealing plate 5.

[0036] The vibrator 7 is installed on the top surface of the sealing plate 5. The vibrator 7 is either pneumatic or electric. The vibrator 7 can also be a vibrator 7 with other power sources. There are two vibrators 7, which are symmetrically installed in the middle area of ​​the sealing plate 5. The uniformity of vibration is achieved by the symmetrical arrangement of the vibrators 7.

[0037] like Figure 2 As shown, several vent holes are evenly distributed on the sealing plate 5, and filter components are connected below the vent holes. There are 9 vent holes arranged in a square matrix, which in turn causes the 9 filter components to also be arranged in a square matrix, achieving a multi-directional filtration path.

[0038] The filter assembly includes a support frame 8 positioned below the vent, with several evenly distributed perforations on the support frame 8. A filter bag 9 is fitted around the outer periphery of the support frame 8. The support frame 8 is a cylindrical mesh cylinder with perforated mesh openings, and the filter bag 9 is a cylindrical cloth bag. The diameter of the vent is equal to the diameter of the mesh cylinder. The mesh cylinder supports the filter bag 9 to increase the filtration area. The perforated mesh facilitates the passage of filtered airflow.

[0039] The operating method of this automatic dust removal filter device is as follows:

[0040] Dust-laden gas enters the lower cavity of housing 1 through inlet 1a. The dust-laden gas comes into contact with filter bag 9, causing large dust particles in the gas to settle down due to gravity and fall into dust collection box 3 through dust outlet 2a. Small dust particles adhere to filter bag 9, allowing only clean gas to enter the upper cavity through filter bag 9 and vent. Finally, clean gas is discharged from the housing through outlet 1b.

[0041] After a period of filtration operation, a significant amount of dust accumulates on the filter bag 9, gradually clogging the filter pores and reducing the filtration efficiency. The vibrator 7 is activated via a control program (which can be a time relay, PLC control, or other control method). The vibrator 7 causes the sealing plate 5 to vibrate, and simultaneously, the filter bag 9 vibrates at a certain frequency, dislodging the dust adhering to the filter bag 9 and allowing it to enter the dust collection box 3 through the dust outlet 2a. After cleaning, the vibrator 7 is shut off via the control program, and the equipment returns to normal filtration operation.

[0042] The specific embodiments described herein are merely illustrative examples of the spirit of this invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or substitute them with similar methods, without departing from the spirit of this invention or exceeding its defined scope.
