Description

TECHNICAL FIELD

[0001] The utility model relates to dust remover technical field, especially a novel pulse cloth bag dust collector. BACKGROUND

[0002] When using the pulse cloth bag dust collector to carry out dust capture operation, dust-containing gas passes through the filter bag, and dust particles are intercepted on the outer surface of the filter bag. At this time, the pulse air valve realizes dust removal by blowing compressed air, and this process is called pulse blowing.

[0003] Due to the powder nature of the dust, part of the dust will adhere to the surface of the filter bag, and pulse blowing can only remove most of the dust. With the extension of the running time, the dust layer on the filter bag gradually thickens, and when the dust layer contacts the water molecules in the air, coagulation and adhesion may occur, which is called bag sticking. Once the dust accumulation on the filter bag reaches the critical value, the filtration efficiency of the dust collector will be significantly reduced, and at this time the filter bag must be replaced to restore the dust removal efficiency, resulting in the service life of the filter bag being generally short, increasing the maintenance cost and the frequency of operation.

[0008] Preferably, a clamping groove is formed on the outer periphery of the top of the filter bag body, a fixing block is fixed on the outer periphery of the top of the bag cage, and a clamping block is fixed at the bottom end of the fixing block and can be clamped into the clamping groove.

[0009] Compared with the prior art, the utility model has the advantages that:

[0010] The utility model provides a novel pulse cloth bag dust collector, through vibration motor as electromagnetic vibration device, this motor contains two electromagnetic coils, changes coil current direction through pulse commutation circuit, makes electromagnet magnetic pole fast alternation according to electromagnetism principle, and the vibration head is caused to vibrate fast by the vibration of permanent magnet attraction and repulsion. Meanwhile, the filter bag support plate is arranged in the dust removal box by spring one, the vibration ring is installed on the top of the fixed groove through spring two, and the bag cage and the filter bag body are connected by the vibration ring and stably installed through the clamping block and the clamping groove. The improvement of the ash removal operation is that, in the fan air volume reduction stage, the vibration of the vibration motor is transmitted to the bag cage and the filter bag body through the filter bag support plate, the spring and the vibration ring, so that they are linked and vibrated to remove dust by vibration, and then the pulse blowing of the back flushing assembly is used to remove dust. The effect of the innovative design is that the vibration dust removal can remove most of the solid dust on the surface of the filter bag body in advance, improve the dust removal efficiency, and through the vibration dust removal and pulse blowing, the adhesion of dust on the filter bag surface can be better addressed. Because the dust has powder properties, part of the dust will adhere to the surface of the filter bag, and the traditional pulse blowing can only remove most of the dust. However, long-term operation will thicken the dust layer, and the dust layer is easy to solidify and stick to form a paste bag phenomenon after contacting water molecules in the air, thereby causing the dust accumulation on the filter bag to reach a critical value, significantly reducing the filtering efficiency of the dust collector, shortening the service life of the filter bag, increasing the maintenance cost, and increasing the operation frequency.

In addition, the cooperation of the components ensures smooth and efficient dust removal process. The design has many benefits, which not only improves the dust removal efficiency and shortens the dust removal time, but also prolongs the service life of the equipment components due to the spring buffer, reduces the subsequent pulse blowing energy, reduces energy consumption, more thoroughly removes dust, avoids filter bag blockage, ensures the continuous and efficient operation of the dust removal system, and improves system performance.

[0020] Vibration component includes vibration motor 53 setting in the middle position of filter bag support plate 5 top, and the both sides of filter bag support plate 5 bottom are provided with side frame 51, and side frame 51 is fixed on the inside wall of dust removal box 1, and the top of side frame 51 is provided with spring one 52, and the top of spring one 52 is fixedly connected with the bottom end of filter bag support plate 5.

[0021] The top of the fixed groove 54 is provided with a vibrating ring 55, the outer periphery of the bottom of the vibrating ring 55 is provided with a spring 56, the bottom end of the spring 56 is fixedly connected with the top of the filter bag supporting plate 5, the filter bag main body 58 is installed in the fixed groove 54 through the vibrating ring 55 and is placed on the bottom of the filter bag supporting plate 5, the outer periphery of the top of the filter bag main body 58 is fixed with the top end of the vibrating ring 55, and the bag cage 57 is installed in the filter bag main body 58 through the vibrating ring 55.

[0022] The outer periphery of the top of the filter bag main body 58 is provided with a clamping groove 573, the outer periphery of the top of the bag cage 57 is fixedly provided with a fixed block 571, the bottom end of the fixed block 571 is fixedly provided with a clamping block 572, and the clamping block 572 can be clamped into the clamping groove 573.

[0023] Working principle:

[0024] The filter bag supporting plate 5 is arranged in the inside of the dust removal box 1 through the spring 52. First, the filter bag main body 58 is installed in the fixed groove 54 through the vibrating ring 55, and it is ensured that the bottom thereof is below the filter bag supporting plate 5. Then, the bag cage 57 is installed in the filter bag main body 58 through the vibrating ring 55, so that the clamping block 572 at the bottom end of the fixed block 571 at the top outer periphery of the bag cage 57 is clamped into the clamping groove 573 at the top outer periphery of the filter bag main body 58, thereby completing the installation operation of the bag cage 57 and the filter bag main body 58.

[0025] The vibrating ring 55 is arranged at the top of the fixed groove 54 through the spring 56. With the elastic force of the spring 56, the vibrating ring 55 can shake together with the filter bag supporting plate 5. When the vibrating ring 55 shakes, the bag cage 57 and the filter bag main body 58 placed thereon will also shake.

[0026] The vibrating motor 53 is an electromagnetic vibration device, which contains two electromagnetic coils. When current flows through these coils, a magnetic field is generated, and then two electromagnets with south and north poles are formed. According to the basic principle of electromagnetism, like poles repel each other, and unlike poles attract each other. By changing the direction of the current, the polarity of the electromagnet will also change accordingly, which is realized by the pulse commutation circuit. The pulse commutation circuit constantly changes the direction of the current flowing through the electromagnet coil, prompting the magnetic poles of the electromagnet to rapidly alternate. The rapid change of the magnetic poles will cause the permanent magnet interacting with the electromagnet to be subjected to attractive and repulsive forces, thereby causing the vibration head to produce rapid vibration.

[0027] The vibration generated by the vibrating motor 53 will be transmitted to the filter bag supporting plate 5, causing the filter bag supporting plate 5 to continuously vibrate. The vibration of the filter bag supporting plate 5 will also drive the vibrating ring 55 to continuously vibrate, thereby causing the bag cage 57 and the filter bag main body 58 to continuously vibrate. Through such vibration, the dust on the surface of the filter bag main body 58 can be shaken off.

[0028] Before the filter bag main body 58 is pulsed by the back blowing assembly 4, when the air volume of the fan is reduced, the bag cage 57 and the filter bag main body 58 are vibrated to remove dust, and then the pulse cleaning is performed. In this way, most of the solid dust on the surface of the bag can be removed.
