Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, specifically a high-efficiency anti-clogging bag dust collector. Background Technology

[0002] Baghouse dust collectors have advantages such as high dust removal efficiency, ability to handle dust of various properties, and adaptability to different working conditions. They are one of the most widely used dust removal equipment in industrial production and are widely used in cement, steel, power, metallurgy, chemical, food and other industries.

[0003] When dust-laden gas passes through the filter bags in a baghouse dust collector, the dust is trapped on the surface of the filter bags, forming a dust layer. Clean gas passes through the filter material and is discharged. Pulse jet cleaning is the mainstream cleaning method for baghouse dust collectors. It uses compressed air to instantly back-blow the filter bags, and the dust falls into the dust hopper for collection. However, in actual use, if there is too much dust, it is easy to adhere to the inner wall of the dust hopper and accumulate, causing blockage. This is not conducive to the subsequent dust falling and thus affects the overall cleaning efficiency. At the same time, the air storage bladder of pulse jet cleaning often does not have pressure monitoring, so it is not easy to detect when the equipment malfunctions. In view of this, we propose a high-efficiency anti-clogging baghouse dust collector. Utility Model Content

[0016] Compared with the prior art, this utility model provides a high-efficiency anti-clogging bag filter, which has the following beneficial effects:

[0017] 1. This high-efficiency anti-clogging baghouse dust collector is equipped with a knocking component to better prevent dust hopper blockage and improve dust removal efficiency. When excessive dust accumulates in the dust hopper, causing blockage and affecting dust removal efficiency, the servo motor is first activated. Then, in conjunction with the disc, through groove, locking block, driven disc, driven shaft, and knocking rod, the knocking rod moves up and down to knock off the dust adhering to the inner wall of the dust hopper. The movement distance of the knocking rod can be adjusted by the threaded rod and knob to achieve different knocking distances, thereby improving dust removal efficiency and preventing dust hopper blockage.

This component, consisting of a round rod, dial, hollow rod, spring tube, wheel, connecting shaft, first gear, second gear, and pointer, works in conjunction with these components. When the pressure inside the air bladder is too high, the spring tube drives the connecting shaft, first gear, second gear, and pointer to rotate in a circular motion within the dial, thus displaying the pressure index inside the air bladder and enabling better real-time monitoring of the pressure.

Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0027] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a high-efficiency anti-clogging bag dust collector, including a body 1, a dust hopper 2 fixedly installed at the bottom of the body 1, a dust box 3 threadedly connected to the bottom of the dust hopper 2, an air inlet 4 opened on the side wall of the body 1, an air storage bag 5 set at the top of the body 1, an air inlet pipe 6 fixedly installed on the outer wall of the air storage bag 5, a bracket 7 fixedly installed inside the body 1, a filter bag 8 fixedly installed inside the top of the bracket 7, and a cover plate 9 snapped onto the top of the body 1.

[0028] In one embodiment of this utility model, a striking component 10 is provided on the body 1. The striking component 10 includes a connecting post 101. One end of the connecting post 101 is fixedly installed at the bottom of the body 1, and a rectangular block 102 is fixedly installed at the other end of the connecting post 101. One end of an L-shaped frame 103 is fixedly installed at the top of the rectangular block 102, and a limit block 104 is fixedly installed at the other end of the L-shaped frame 103. A servo motor 105 is fixedly installed at one end of the rectangular block 102, and a rotating shaft 106 is rotatably installed inside the rectangular block 102. One end of the rotating shaft 106 is fixedly installed at the output end of the servo motor 105, and a disc 107 is fixedly installed at the other end of the rotating shaft 106. A through groove 108 is opened inside the disc 107. A locking block 109 is slidably installed inside. A driven plate 1010 is fixedly installed on one end of the outer wall of the locking block 109. A threaded rod 1011 is threadedly connected inside the locking block 109. The threaded rod 1011 passes through the disc 107 and the locking block 109. A knob 1012 is fixedly installed on the top of the threaded rod 1011. A driven shaft 1013 is rotatably installed inside the other end of the driven plate 1010. A knocking rod 1014 is rotatably installed on the other end of the driven shaft 1013. Multiple sets of filter bags 8 and cover plates 9 are provided. Two sets of knocking components 10 are provided. Two sets of connecting columns 101 and limiting blocks 104 are provided in each set of knocking components 10. The through groove 108 has the same shape as the locking block 109, and the volume of the locking block 109 is smaller than that of the through groove 108.

[0029] In this embodiment, dust-laden gas enters the machine body through the air inlet 4. After the gas 1 enters, the filter bag 8 filters the dust-laden gas, trapping the dust on the surface of the filter bag 8. The purified gas is discharged from the machine body 1 through the open cover 9. During the filtration process, the bracket 7 supports the filter bag 8, and the air inlet pipe 6 impacts the dust on the surface of the filter bag 8, causing it to fall into the dust hopper 2 at the bottom. After the dust is collected in the dust hopper 2, it finally falls into the dust box 3. When too much dust accumulates in the dust hopper 2, causing blockage and affecting the dust removal efficiency, the connecting column 101 provides support for the entire striking assembly 10, starts the servo motor 105, and drives the rotating shaft 106 to rotate inside the rectangular block 102. The disc 107 rotates synchronously with the rotating shaft 106, and the locking block 109 rotates with the disc 107. The locking block 109 can slide freely in the through groove 108, and the locking block 109 drives the driven disc 1010 to rotate. The driven disc 1010 drives the driven shaft 1013 to rotate synchronously, causing the knocking rod 1014 to swing. During the swing, the knocking rod 1014 is restricted by the limiting block 104 and can only move up and down. Its end periodically knocks the outer wall of the ash hopper 2, causing the dust particles attached to the inner wall of the ash hopper 2 to be shaken off from the inner wall. When it is necessary to adjust the movement distance, the knob 1012 is rotated, and the threaded rod 1011 moves linearly under the action of the internal thread of the locking block 109, which drives the driven disc 1010 and the driven shaft 1013 to move along the axial direction of the threaded rod 1011. The eccentricity of the driven disc 1010 increases, which indirectly adjusts the up and down reciprocating movement distance of the knocking rod 1014. Specifically, it increases the amount of the knocking rod 1014 protruding inside the limiting block 104, thereby better adapting to the smaller size of the ash hopper 2, thereby improving adaptability, effectively improving the dust removal efficiency, and preventing the ash hopper 2 from clogging.

[0030] In one embodiment of this utility model, a monitoring component 11 is provided on the air reservoir 5. The monitoring component 11 includes a round rod 111. One end of the round rod 111 is fixedly installed on the top of the air reservoir 5, and a scale 112 is fixedly installed on the other end of the round rod 111. One end of a hollow rod 113 is fixedly installed on the inner wall of the scale 112, and one end of a spring tube 114 is fixedly installed on the outer wall of the hollow rod 113. A wheel 115 is fixedly installed on the other end of the hollow rod 113, and the other end of the spring tube 114 is rotatably mounted. One end of the shaft 116 is connected to the other end of the shaft 116, and the other end of the first gear 117 is rotatably mounted on the other end of the shaft 116. The other end of the first gear 117 is fixedly mounted on the wheel 115. The outer wall of the wheel 115 is rotatably mounted with the second gear 118. The first gear 117 meshes with the second gear 118. The pointer 119 is fixedly mounted on the outside of the second gear 118. The internal spaces of the round rod 111, the hollow rod 113 and the spring tube 114 are connected. One end of the dial 112 is made of transparent material.

[0031] In this embodiment, the round rod 111 serves as the initial channel for pressure transmission. When the pressure inside the air bladder 5 increases, the spring tube 114 deforms under pressure, causing the connecting shaft 116 to swing around the hinge point. This converts the linear displacement of the spring tube 114 into the angular displacement of the connecting shaft 116. When the connecting shaft 116 swings, it applies a force to the first gear 117. Under the force of the connecting shaft 116, the first gear 117 rotates around the hollow rod 113. The rotation of the first gear 117, through the interaction force between the teeth, drives the second gear 118 to rotate in the opposite direction, thus transmitting the rotational motion of the first gear 117 to the second gear 118. At the same time, the second gear 118 drives the pointer 119 to move in a circular trajectory. The operator only needs to observe the direction of the pointer 119 on the dial 112 to intuitively obtain the pressure index inside the air bladder 5, thereby better monitoring the pressure inside the air bladder 5 in real time.

Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
