Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a bag dust removal device for a bag dust collector. Background Art

[0002] During the daily use of the bag dust collector, the filtered dust impurities will be adsorbed on the surface of the bag. If they are not cleaned in time, the dust removal efficiency of the bag dust collector will be affected. The current bag dust collector is equipped with pulse backblowing, which uses compressed air at a certain pressure (usually 5~7kg) to blow back the bag in a pulsed manner through a gas nozzle, so that the powder adsorbed on the bag is separated from the bag.

[0003] However, the existing pulse backflush still has the following shortcomings in actual use:

[0004] 1. The output in factory production is relatively high. There are many bags in a dust collector and the length is relatively long, usually 1.5~2 meters, with more than 100 bags. The air nozzle is generally installed at a height of 5~10 cm from the bag opening, which causes the other end of the bag to be far away from the nozzle. During the back-blowing dust removal process, the force on the bag is uneven, especially at the position far from the nozzle, which often leads to poor dust removal effect due to insufficient air pressure;

[0005] 2. The bag is easily damaged under the impact of long-term pulse pressure, causing dust to fly all over the sky and pollute the air;

[0006] 3. Although the compressed air ejected by the back-blowing dust removal has been freeze-dried, it is inevitable that it will contain a certain amount of moisture. If the dust on the bag is not effectively separated, it is easy to absorb water and stick to the bag, making it more difficult to fall off, thus affecting the dust removal effect;

[0007] 4. During the bag dust removal process, due to the unsatisfactory pulse backblowing effect, a considerable amount of powder on the bag is stuck to the bag and is difficult to fall off. For this reason, the staff needs to stop the induced draft fan and manually knock and clean it, which is time-consuming and laborious, affecting production;

[0008] Therefore, there is an urgent need for a dust removal device for a bag filter that can overcome the above-mentioned shortcomings. Utility Model Content

In the description, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present invention and are for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific direction.

[0029] Please refer to the instruction manual Figure 1-2 , the utility model provides a technical solution:

[0030] Embodiment 1, a bag dust removal device for a bag dust collector comprises an expansion ring 7, the lower surface of the expansion ring 7 is provided with a plurality of expansion rods 8 which are arranged in an orderly manner along the circumferential direction of the expansion ring 7 and are used to expand the bag, the structure of the expansion ring 7 and the expansion rod 8 is the same as the existing bag expansion structure, the expansion rod 8 is a hollow structure, the upper surface of the expansion ring 7 is provided with a plurality of through holes 6 which correspond to the plurality of expansion rods 8 at the lower part of the expansion ring 7, the through holes 6 penetrate the expansion ring 7 and are connected to the corresponding inner cavities of the expansion rods 8, the upper part of the expansion ring 7 is provided with a mounting ring 3 which corresponds to and fits the expansion ring 7, the lower surface of the mounting ring 3 is provided with a vibration mechanism which can drive the expansion rods 8 to vibrate and shake off dust and impurities on the surface of the bag, specifically, the vibration mechanism comprises an inner rod 4, a knocking rod 5 and a vibrator 11, the lower surface of the mounting ring 3 is provided with a plurality of inner rods 4 which correspond to the through holes 6 and are arranged along the axial direction of the expansion rods 8, the length of the inner rod 4 The length is adapted to the length of the expansion rod 8, the inner rod 4 is inserted into the inner cavity of the expansion rod 8 through the through hole 6, and the rod body of the inner rod 4 is provided with several knocking rods 5 which are arranged in an orderly manner along the axial direction of the inner rod 4 and conflict with the inner wall of the expansion rod 8. A vibrator 11 is provided at the lower end of the inner rod 4. In order to ensure that the vibrator 11 can effectively drive the inner rod 4 to vibrate left and right, the vibrator 11 is an electric vibrator or an electromagnetic vibrator, wherein the centrifugal force generated by the eccentric wheel in the electric vibrator will cause the rod body of the inner rod 4 to vibrate left and right, and the magnetic field change generated by the electromagnetic vibrator will also cause the vibrator to vibrate left and right, thereby driving the rod body of the inner rod 4 to vibrate left and right. The upper surface of the mounting ring 3 is provided with several wire holes 10 that penetrate the mounting ring 3 and correspond to the inner rod 4 one by one. The wires 9 connected to the vibrator 11 are built into the inner rod 4 and pass through the wire holes 10. After the several wires 9 are connected to the power supply line of the bag dust collector and a switch is set for control;

[0031] When the dust on the surface of the cloth bag needs to be cleaned, the staff only needs to start the vibrator 11, and the vibrator 11 drives the inner rod 4 to vibrate left and right. The several knocking rods 5 on the rod body of the inner rod 4 can synchronously drive the expansion rod 8 to vibrate. Since the cloth bag is arranged on the outside of the expansion rod 8, the vibration of the expansion rod 8 can effectively vibrate and shake off the dust and impurities on the surface of the cloth bag.

[0032] Embodiment 2, in order to ensure the service life of the vibration mechanism, the inner rod 4 and the knocking rod 5 are both made of rubber or stainless steel. Preferably, rubber material is used, and hard rubber is used. The inner rod 4 and the knocking rod 5 made of hard rubber not only ensure the vibration drive of the expansion rod 8, but also have a certain flexibility, thereby avoiding damage to the inner rod 4 and the knocking rod 5; if stainless steel material is used, although the inner rod 4 and the knocking rod 5 have sufficient strength, it will generate relatively large noise. For this reason, a rubber sleeve can be provided on the end of the knocking rod 5.

[0033] Embodiment three, during the expansion process of the cloth bag by the expansion rod 8, only the outer side of the expansion rod 8 is in contact with the cloth bag. In order to ensure the vibration shaking-off efficiency of the dust on the surface of the cloth bag, the knocking rod 5 and the inner rod 4 are arranged perpendicular to each other, one end of the knocking rod 5 is fixedly connected to the rod body of the inner rod 4, and the other end of the knocking rod 5 is facing the side away from the central axis of the expansion ring 7. This ensures that the knocking rod 5 can effectively vibrate and knock on the side of the expansion rod 8 in contact with the cloth bag, thereby effectively providing the vibration shaking-off efficiency of the dust.

[0034] Embodiment 4. During the process of the vibrator 11 driving the inner rod 4 to vibrate, the vibrator 11 will also move with the inner rod 4, which may not only cause damage to the vibrator 11, but also affect the vibration driving effect of the vibrator 11 on the inner rod 4. For this reason, a bottom plate 12 matched with the inner diameter of the expansion rod 8 is provided at the lower end of the inner rod 4, and the vibrator 11 is fixedly mounted on the bottom plate 12, and the lower end of the expansion rod 8 is connected to the vibrator 11.

[0035] Embodiment 5: During the vibration of the vibration mechanism, in order to prevent the mounting ring 3 from shaking, a limit cover 1 threadedly connected to the outer wall of the expansion ring 7 is provided on the upper part of the expansion ring 7, and an opening 2 corresponding to and matching the inner ring of the expansion ring 7 is provided on the upper surface of the limit cover 1.
