Description

Technical Field

[0001] The utility model relates to the technical field of bag dust removal, and particularly relates to a dust removal bag cage with a large amount of cleaning ash. Background Art

[0002] A bag filter is an efficient dry dust collector. The bag filter relies on a cloth bag made of a fiber filter material to purify air. The dust filtration mechanism of the cloth bag includes screening, inertial collision, interception, diffusion, electrostatic and gravity effects, etc. When the dust particle size is larger than the pores between the fibers in the filter material or the pores between the dust deposited on the filter material, the dust is sieved out.

[0003] When a large amount of dust accumulates outside the dust removal cloth bag, resulting in excessive resistance during operation and reaching the set value, it is necessary to clean the ash. There are various ash cleaning methods for bag filters, such as mechanical vibration ash cleaning, reverse blowing ash cleaning, pulse ash cleaning, etc. For different ash cleaning methods, the amount of dust escaping during ash cleaning is different, and the amount of dust in the residual material after ash cleaning is also different. For the ash cleaning methods of reverse blowing ash cleaning and pulse ash cleaning, the structure of the cage inside the dust removal cloth bag is different, which also has different effects on the ash cleaning effect. The existing dust removal bag cages have little effect on ash cleaning and cannot improve the ash cleaning effect. Content of the Utility Model

[0004] Therefore, the utility model provides a dust removal bag cage with a large amount of cleaning ash to promote ash cleaning and improve the ash cleaning effect.

[0005] The technical solution of the utility model is as follows:

[0006] A dust removal bag cage with a large amount of cleaning ash includes a clamping cover, a frame beam, a ring rib and a bottom cover. The clamping cover and the bottom cover are circular. The clamping cover and the bottom cover are arranged at both ends. The frame beam is arranged between the clamping cover and the bottom cover. The number of the frame beams is multiple. The middle parts of the multiple frame beams are connected by a ring rib. A through hole is opened in the center of the clamping cover. A ring groove is opened in the direction of the frame beam on the clamping cover. The inner side of the ring groove is the first clamping convex and the outer side is the second clamping convex. The first clamping convex is connected to the frame beam and the convex height is higher than that of the second clamping convex. The frame beam is in the shape of a wind guiding blade and is divided into multiple sections along the axial direction. The ring rib is arranged at the boundary between two adjacent sections of the frame beam. The wind guiding directions of two adjacent sections of the frame beam are opposite.

[0007] As a preference, the frame beam is divided into four sections along the axial direction. The frame beam is successively the first section, the second section, the third section and the fourth section from near the clamping cover to far from the clamping cover. The frame beams of the first section and the third section guide the wind obliquely along the radial direction. The second section and the fourth section guide the wind obliquely in another direction along the radial direction. When cleaning the ash, the air flow blows out from the inside of the cage to the outside of the cage. The wind guiding directions of two adjacent sections among the four sections are opposite. If the wind guided by one section is counter-rotating, the other section is co-rotating. Blowing air into the filter bag generates a torsional air flow in sections, which helps to clean a large amount of ash.

[0008] As a preference, the bottom cover is basin-shaped, with a through hole opened at the center of the bottom cover, and the side of the bottom cover is fused with the outer end of the beam. The through hole at the center of the bottom cover helps to increase the effective area for the filter bag to work and improve the utilization rate.

[0009] As a preference, the clamping cover, beam, ring rib and bottom cover are of an integral structure, and the clamping cover, beam, ring rib and bottom cover are made of plastic or metal. Being made of plastic integrally or metal integrally can enhance the structural strength and reduce the cost at the same time.

[0010] The working principle and beneficial effects of the present utility model are as follows:

[0011] The large dust cleaning amount dust removal cloth bag cage provided by the present utility model can guide the air flow duct during dust cleaning, so that the air flow produces a segmented swirling blowing effect on the filter bag, and improves the dust cleaning effect.

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0019] Embodiment 1: Please refer to Figure 1 and Figure 2As shown in the figure, this embodiment provides a dust removal cloth bag cage frame with a large dust cleaning capacity, which includes a clamping cover 1, a beam 2, a ring rib 3 and a bottom cover 4. The clamping cover 1 and the bottom cover 4 are circular, the clamping cover 1 and the bottom cover 4 are arranged at both ends, the beam 2 is arranged between the clamping cover 1 and the bottom cover 4, and the number of beams 2 is multiple. The middle parts of these beams 2 are connected by a ring rib 3. A through hole is opened in the center of the clamping cover 1 for gas to flow through. The clamping cover 1 is provided with a ring groove 12 in the direction towards the beam 2. The inner side of the ring groove 12 is the first clamping protrusion 13 and the outer side is the second clamping protrusion 11. The first clamping protrusion 13 is connected to the end of the beam 2 and the protruding height is higher than that of the second clamping protrusion 11. The beam 2 is in the shape of a wind guiding blade and is axially divided into four sections. The ring rib 3 is arranged at the boundary between two adjacent sections of the beam 2, and the wind guiding directions of two adjacent sections of the beam 2 are opposite.

[0020] The beam 2 is successively the first section, the second section, the third section and the fourth section from the direction close to the clamping cover 1 to the direction away from the clamping cover 1. The beams 2 in the first section and the third section guide the wind radially inclined, and the second section and the fourth section guide the wind radially inclined in another direction. During dust cleaning, the air flow blows out from the inside of the cage frame to the outside of the cage frame. The wind guiding directions of two adjacent sections among the four sections are opposite. If the wind guided by one section is counter-rotating, then the other section is co-rotating.

[0021] The clamping cover 1, the beam 2, the ring rib 3 and the bottom cover 4 can be an integral structure or composed of different materials. When using an integral structure, the clamping cover 1, the beam 2, the ring rib 3 and the bottom cover 4 are made of plastic or metal.

[0022] Embodiment 2: Please refer to Figure 3 and Figure 4 As shown in the figure, the structure of the dust removal cloth bag cage frame with a large dust cleaning capacity in this embodiment is substantially the same as that in Embodiment 1. The difference is only that a through hole is opened in the center of the bottom cover 4, and the side of the bottom cover 4 is fused with the outer end of the fourth section of the beam 2 to enhance the structural strength.

[0023] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
