Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to an air circulation device with a dust filtering function. Background Art

[0002] Bag dust collector is a dry dust filtering device, which 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 dust-containing gas. When the dust-containing gas enters the bag dust collector, the large particles and high specific gravity dust settle down due to gravity and fall 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 dust collector is an important part of factory air circulation dust removal.

[0003] The dust bag can be regarded as the heart of the bag dust collector. It is generally called a dust bag or a dust filter bag. The dust bag is a key part in the operation of the bag dust collector. Usually the cylindrical filter bag is hung vertically in the dust collector. In actual use, the high-speed airflow entering the bag dust collector will drive the dust to impact the dust bag, which will affect the service life of the dust bag. Based on this, an air circulation device with dust filtering function is provided. Utility Model Content

The partition 104 is welded and fixed to the inner side of the dust removal box 101. A mounting hole 2 is opened on the top of the partition 104 and penetrates to the bottom of the partition 104. The mounting hole 2 is used for the installation of a dust bag 5. The bottom of the partition 104 is located outside the mounting hole 2 and is welded and fixedly connected with a fixed ring tube 3. The bottom of the fixed ring tube 3 is fixedly connected with a fixed ring 4. An outer protective component 7 is installed on the inner side of the fixed ring tube 3 and the fixed ring 4. The outer protective component 7 is used to protect the outer side of the dust bag 5.

[0025] The outer protection component 7 includes an annular block 701 and a protection grille tube 702 .

[0026] The protective grille tube 702 is fixed to the bottom of the annular block 701 , the annular block 701 is attached to the top of the fixing ring 4 , and the protective grille tube 702 passes through the inner side of the fixing ring 4 .

[0027] The dust removal bag 5 includes a C-shaped clamping ring 501 and a bag body 502. The C-shaped clamping ring 501 is clamped on the inner side of the mounting hole 2. The bag body 502 is fixed to the bottom of the C-shaped clamping ring 501 and extends to the inner side of the protective grille tube 702. The protective grille tube 702 is used to protect the outer side of the bag body 502 to prevent dust from directly impacting the bag body 502.

[0028] The outer diameter of the annular block 701 is smaller than the inner diameter of the mounting hole 2 , and the inner diameters of the annular block 701 and the protective grille tube 702 are larger than the outer diameter of the bag body 502 .

[0029] An annular groove 703 is formed on the inner side of the annular block 701 , and the annular groove 703 is used for lifting the annular block 701 .

[0030] An inner support assembly 6 extending to the interior of the bag body 502 is further provided above the partition 104 . The inner support assembly 6 includes a top cover 601 and a support frame 602 .

[0031] The top cover 601 is sleeved on the top of the C-shaped clamp 501 and fits with the upper surface of the partition 104. The support frame 602 is fixed to the bottom of the support frame 602 and passes through the C-shaped clamp 501 to the inside of the bag body 502 to form support for the inside of the bag body 502.

[0032] The bag filter 1 further includes an air inlet pipe 102 , an exhaust pipe 103 , an electronic pulse valve 105 , and a spray pipe 106 .

[0033] The air inlet pipe 102 and the exhaust pipe 103 are symmetrically fixed on both sides of the outer wall of the dust removal box 101 and communicate with the inner cavity of the dust removal box 101 , and the ends of the air inlet pipe 102 and the exhaust pipe 103 are respectively located below and above the partition 104 .

[0035] In the present embodiment, it should be additionally explained that the electronic pulse valve 105 is connected to the external air pump. When a lot of dust adheres to the outside of the bag body 502, the external air pump and the electronic pulse valve 105 can be started to allow high-pressure airflow to pass through the blow pipe 106 and impact the inside of the bag body 502, thereby causing the bag body 502 to vibrate and achieve the effect of cleaning the dust.

[0036] During daily use of the bag dust collector 1, the protective grille tube 702 forms a shield on the outside of the bag body 502, and the dust-containing air entering the dust removal box 101 will first come into contact with the protective grille tube 702, wherein larger dust particles and some small dust particles are intercepted, while the other part of the small dust particles will pass through the air holes on the protective grille tube 702 and come into contact with the bag body 502, and then be intercepted by the bag body 502. Through the setting of the protective grille tube 702, compared with the traditional structure in which the airflow directly impacts the bag body 502, the protective grille tube 702 can form a blocking effect on the airflow, so that the flow rate of the airflow impacting the bag body 502 becomes smaller, thereby reducing the impact force on the bag body 502, and then effectively reducing the impact damage to the bag body 502, and effectively extending the service life of the bag body 502.

[0037] Please refer to Figures 1 to 3 The outer protection component 7 can be integrally formed by a plastic injection molding process, and ventilation holes are provided on the outer side and the bottom of the protection grille tube 702.

[0038] In this embodiment: this structure enables the outer protection component 7 to have strong wear resistance and corrosion resistance, and the production process is simple, which is easy to promote production.
