Description

Technical Field

[0001] This utility model relates to a pressure cap for sealing the opening of a damaged dust collector bag in the online dust collection system, belonging to the field of dust collection technology in the metallurgical industry. Background Technology

[0002] Baghouse dust collectors have advantages such as high dust removal efficiency, strong adaptability, and simple operation, and are widely used in the treatment of dusty flue gas in industry. A typical baghouse dust collector has over a thousand filter bags, and larger dust collectors have over ten thousand. Due to inconsistent manufacturing quality of the filter bags, or design reasons such as uneven airflow distribution, insufficient distance between the filter bag and the dust collector shell, or the approaching end of its service life, a filter bag may become damaged, resulting in an increase in the dust content of the emitted flue gas.

[0003] The usual approach to damaged filter bags is to replace them. However, when there is a lack of suitable spare filter bags on site or when emergency startup is required, waste cloth is usually rolled into a cone shape to seal the opening of the damaged filter bag before it can be put back into use. Filter bags sealed in this way have disadvantages such as poor sealing effect at the bag opening and the sealant being easy to fall off. Utility Model Content

[0004] The purpose of this invention is to provide a cap for sealing the opening of a damaged dust collector bag, which can quickly seal the opening of the damaged dust collector bag, extend the service life of the dust collector bag, and solve the problems existing in the background technology.

[0005] The technical solution of this utility model is:

[0006] A pressure cap for sealing the opening of a damaged dust collector bag in an online system includes a blowpipe, a blowpipe branch pipe, a metal gasket, a nut, a screw, a cover plate, and a rubber gasket. The rubber gasket is glued to the bottom of the cover plate, and a screw is welded to the center of the top of the cover plate. A nut is provided on the screw, and a metal gasket is provided on the nut. The screw is inserted into the blowpipe branch pipe, which is connected to the blowpipe.

[0007] The metal washer on the nut is fitted onto the screw.

[0008] The inner diameter of the metal gasket matches the diameter of the screw, and the outer diameter of the metal gasket is larger than the outer diameter of the jet branch pipe.

[0009] The diameter of the screw is smaller than the inner diameter of the jet branch pipe.

[0010] The outer contour of the nut is larger than the outer diameter of the blow-off branch pipe.

[0011] The size of the rubber gasket glued under the cover plate matches the size of the damaged dust collector bag opening.

[0012] The beneficial effects of this utility model are: It has a simple structure and is easy to manufacture. It can quickly seal damaged dust collector bag openings, extending the service life of the dust collector bags. The seal is tight with no dust leakage and remains secure for a long time. It prevents dust-laden flue gas from entering the clean air chamber through damaged bag openings, thereby effectively controlling the increase in dust content in the flue gas caused by individual bag damage.

[0015] The present invention will be further described below with reference to the accompanying drawings and examples.

[0016] See attached document Figure 1 A pressure cap for sealing the opening of a damaged dust collector bag in an online system includes a blow pipe 1, a blow branch pipe 2, a metal gasket 3, a nut 4, a screw 5, a cover plate 6, and a rubber gasket 7. The rubber gasket 7 is glued to the bottom of the cover plate 6, and the screw 5 is welded to the center of the top of the cover plate 6. The screw 5 is equipped with a nut 4, and the nut 4 is equipped with a metal gasket 3. The screw 5 is inserted into the blow branch pipe 2, and the blow branch pipe 2 is connected to the blow pipe 1.

[0017] In this embodiment, refer to the appendix Figure 1 A pressure cap for sealing the opening of a damaged dust collector bag includes a blowpipe 1, a blowpipe branch pipe 2, a metal gasket 3, a nut 4, a screw 5, a cover plate 6, and a rubber gasket 7. The rubber gasket 7 is glued to the underside of the cover plate 6, and its size matches the size of the damaged dust collector bag opening. The screw 5 is welded to the center of the cover plate 6, and a nut 4 is mounted on the screw 5. A metal gasket 3 is mounted on the nut 4.

[0018] The diameter of screw 5 is smaller than the inner diameter of the jet branch pipe 2.

[0019] The inner diameter of the metal washer 3 matches the diameter of the screw 5, and the outer diameter of the metal washer 3 is larger than the outer diameter of the jet branch pipe 2. When the metal washer 3 is subjected to the upward tightening force of the nut 4, it can press against the jet branch pipe 2.

[0020] The specific usage method is as follows:

[0021] After the bag filter is damaged, first insert the screw 5 into the blow-through branch pipe 2 so that the rubber gasket 7 completely covers the top 8 of the bag cage; then tighten the nut 4 upwards. When the metal gasket 3 is subjected to the upward tightening pressure of the nut 4, it can press against the blow-through branch pipe 2. Under the condition of interaction force, the compressive force is transmitted to the rubber gasket 7 through the screw 5. The rubber gasket 7 presses against the top 8 of the bag cage, thereby sealing the damaged bag 9 and preventing dust from entering the clean air chamber, thus completing the work of sealing the opening of the damaged bag.
