Description

Technical Field

[0001] The invention relates to the technical field of dust removal bags, in particular to a cylindrical pulse corrugated bag for a dust collector. Background Art

[0002] A dust collector is a device used to treat particulate matter and dust in industrial waste gas. It is widely used in chemical, electric power, metallurgy, building materials and other industries. Among them, the pleated dust bag is the core component of the dust collector. It is usually made of special fiber materials that are resistant to high temperature, corrosion and wear, and has good filtering performance and a long service life. The design of the pleated dust bag increases the filtering area of ​​the bag in a limited space, improves the dust removal efficiency, and reduces the footprint of the equipment. It is widely used in dust control in the power, steel, cement, chemical and other industries, especially in dealing with high temperature, high humidity and high concentration dust. It can not only effectively remove dust in the production process, but also protect production equipment, improve product quality, and improve the working environment. It meets the dual needs of modern industry for environmental protection and energy efficiency. The cylindrical pulse pleated bag is one of them.

[0003] However, in the prior art, after the cylindrical pulse pleated bag has been used for a period of time, the particulate matter and dust contained in the industrial waste gas are captured by the filter material layer, and dust particles gradually accumulate on the bag surface, causing dust particles to adhere to the outer surface and become clogged. This will seriously affect the filtering efficiency and overall working performance of the bag, and may even cause harm to the entire dust removal system. Therefore, it is very important to clean the cylindrical pulse pleated bag regularly; and the existing cleaning method is to first remove the cylindrical pulse pleated bag, and then beat and blow it, which makes the cleaning process cumbersome and consumes a lot of time and energy. Summary of the invention

In the initial state, the double-sided side guard mechanism and the flapping mechanism are located on the outside of the cloth bag body and have no force on the cloth bag body. When cleaning dust, the double-sided side guard mechanism and the flapping mechanism on both sides act on the cloth bag body.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, the dust-laden airflow first enters the dust collector housing, the dust particles are intercepted by the bag body, the filtered clean airflow passes through the inside of the bag body, and is finally discharged through the air outlet of the dust collector. At the same time, the double-sided retaining mechanism located on both sides of the bag body is started, and the bag body is squeezed toward the middle at the same time.

The first connecting frame pushes the long plate and thus pushes the rubber plate toward the bag body. The two groups of rubber plates simultaneously move toward the middle to squeeze the bag body. By simultaneously changing the length of the extension of the movable rods of the two groups of first electric cylinders, the spacing between the two groups of rubber plates is controlled, thereby controlling the force of the beating on the bag body and the amplitude of the swing back and forth, thereby ensuring that the dust is cleaned to the maximum extent.

[0021] 3. In the present invention, the dust-laden airflow first enters the dust collector housing and passes through the external space of the bag body. In this process, larger dust particles directly hit the surface layer due to inertia and are captured, while smaller dust particles are intercepted by the dense woven layer as the airflow passes through the surface layer. The dense woven layer has a dense pore structure and can effectively intercept these particles. At the same time, multiple cage frames made of carbon steel support the entire bag body to ensure the pleated shape of the bag body. The pleated structure of the bag increases the filtration area and improves the filtration efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Embodiment 3: According to Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, a cylindrical pulse corrugated bag for a dust collector comprises a bag frame 1, a bag body 2 is fixedly installed in the middle of the bag frame 1, a mounting frame 5 is fixedly connected to the lower end of the bag frame 1, and a double-sided side guard mechanism 3 and a beating mechanism 4 are movably connected to the upper side of the mounting frame 5. The double-sided side guard mechanism 3 is used to abut against the bag body 2 on both sides during cleaning, and the beating mechanism 4 is used to beat the bag body 2. The bag body 2 is folded and surrounded into a ring shape, and is composed of a surface layer 21, a densely woven layer 22, a cage frame 23 and an inner circle layer 24. A plurality of groups of cage frames 23 are vertically distributed and arranged between the densely woven layer 22 and the inner circle layer 24, and the surface layer 21 is arranged on the outer side of the densely woven layer 22.

The double-sided side guard mechanism 3 and the beating mechanism 4 are located inside the bag frame 1, and the double-sided side guard mechanism 3 and the beating mechanism 4 are both located on the outer side of the bag body 2.

[0037] In this embodiment, the bag is installed inside the dust collector by means of the mounting frame 5, so that the bag frame 1 pulls the bag body 2 to be in a vertically open state, and the dust-laden airflow first enters the dust collector casing and passes through the external space of the bag body 2. In this process, larger dust particles directly hit the surface layer 21 due to inertia and are captured, while smaller dust particles are intercepted by the densely woven layer 22 as the airflow passes through the surface layer 21. The densely woven layer 22 has a dense pore structure and can effectively intercept these particles.

In the initial state, the double-side retaining mechanism 3 and the beating mechanism 4 are located on the outside of the bag body 2 and do not exert force on the bag body 2;

[0039] The dust-laden airflow first enters the dust collector housing and passes through the outer space of the bag body 2. In this process, the larger dust particles directly hit the surface layer 21 due to inertia and are captured, while the smaller dust particles are intercepted by the densely woven layer 22 as the airflow passes through the surface layer 21. The filtered clean airflow passes through the inner ring layer 24, passes through the inside of the bag body 2, and is finally discharged through the air outlet of the dust collector, thereby achieving the purpose of dust removal.

[0040] As time goes by, dust will gradually accumulate on the surface of the bag body 2 to form an ash layer. At the same time, the first electric cylinder 333 located on both sides of the bag body 2 is started, and the movable rod of the first electric cylinder 333 is extended and exerts a force on the first right-angle plate 332 and pushes one end thereof. The other end of the first right-angle plate 332 is fixed to the outer first flip frame 322 through the first coupling shaft 331. Therefore, the first right-angle plate 332 exerts a torque force on the outer first flip frame 322, so that the two parallel groups of first flip frames 322 move in an arc around the connection point with the mounting frame 5, and drive the first connecting frame 321 to move in an arc. The first connecting frame 321 pushes the long plate 312 and thereby pushes the rubber plate 311 to approach the bag body 2. The two groups of rubber plates 311 simultaneously approach the middle and squeeze the bag body 2.

[0041] Next, the third electric cylinder 433 on both sides of the bag body 2 is controlled to start, and the movable rod of the third electric cylinder 433 performs alternating movement of extension and contraction in a short period of time, applying thrust and pulling force to the second right-angle plate 432, thereby driving the two sets of second flip frames 425 parallel to each other to swing, and under the connection of the second connecting frame 424, the mounting rod 422 and the mounting plate 421, the flapping plate 411 is driven to swing and flap the two sides of the bag body 2, and the upper part of the bag body 2 is subjected to the traction force of the bag frame 1, so that the two sides of the bag body 2 that are flapped swing back and forth, so that the dust accumulated on the surface of the bag body 2 falls off;

[0042] By simultaneously changing the length of the extended active rods of the two groups of first electric cylinders 333 and controlling the spacing between the two groups of rubber plates 311, the force of beating on the bag body 2 and the amplitude of the swing back and forth are controlled to ensure that the dust is cleaned to the maximum extent.
