Problems solved by technology

However, due to the rigid material of the existing bag cage, the frequent contact between the filter bag and the bag cage will easily cause the wear of the filter bag, affect the service life of the filter bag, increase the production cost and production safety, and the function of the existing filter bag cage Single, not conducive to improving production efficiency

Embodiment Construction

[0017] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0018] Such as figure 1 As shown, the dust-laden gas enters from the dust collector inlet 1. After passing through the inlet, the horizontally flowing gas becomes a rotating gas in the cone 4, and it will rotate around the side wall of the dust collector and move downward. Under the action of centrifugal force, the gas The large particles in the gas will be separated and fall into the ash hopper 5; the setting of the cone can effectively reduce the abrasive impact of the particles in the gas on the air tube 11 and the filter bag 12. The particles that cannot be separated will continue to move with the gas, and the gas will continue to move to the center and the lower end of the cone 4 at the same time, and when the gas reaches the lower end of the cone 4, it will turn and move upward to become an internal spiral gas. The inner swirling gas rotates upwards from...

Abstract

The invention relates to a bag cage of a bag type dust collector.A plurality of gas-filling tubes (11) form the bag cage; the two ends of each gas-filling tube (11) are respectively connected with two opposite gas filling openings (21) in a gas-filling head (10) in a sealing mode; the gas-filling tubes (11) which are equal in length are connected with the gas-filling openings (21) in the sealing mode; and the uniformly-distributed gas-filling tubes (11) form the bag cage. The bag cage of the bag type dust collector is soft in material and can effectively prolong the service life of a filter bag.

Description

technical field [0001] The invention relates to a bag cage used in a bag dust collector. Background technique [0002] Bag filter is widely used to purify dusty gas produced in metallurgy, mining, chemical industry, cement, power generation, grain processing and other industries. The working principle of the bag filter is to introduce the dust-laden gas into the filter bag and let it pass through the filter bag in the filter bag, and the dust particles will be intercepted and left on the surface of the filter bag to form a dust layer. The clean air passes through the filter bag and then exits the dust collector. [0003] The filter bag in the bag filter needs to be supported and fixed by the bag cage. The existing bag cage is usually made of rigid material, including vertical ribs and ring ribs. The vertical ribs and ring ribs form a cylindrical keel, and the dust bag is fixed on the keel by fixing means. However, due to the rigid material of the existing bag cage, the fr...
