Description

Technical Field

[0001] This utility model relates to the technical field of baghouse dust collectors, specifically a pulse rotary jet cleaning device. Background Technology

[0002] Baghouse dust collectors are high-efficiency dust removal devices that use fiber filter media to filter and separate dust-laden gas. They are widely used in industries such as power, metallurgy, chemical and building materials. After long-term use, baghouse dust collectors usually use the pulse rotary jet cleaning device on their inner side to spray high-pressure gas from the inside of the filter bag to remove the dust and impurities accumulated on the surface of the filter bag.

[0003] When cleaning dust from the surface of filter bags, existing blow-jet devices are mainly based on motors. The output end of the motor is connected to a reducer, and a rotating arm is set on one side of the reducer. Gears are fixed to the output end of the reducer and one end of the rotating arm, and the two gears mesh with each other. A blow-jet pipe is fixed to the rotating arm at the output end of the high-pressure air tank. One end of the blow-jet pipe is rotatably connected to a guide tube, and the other end of the guide tube is connected to the high-pressure air tank. The motor drives the reducer to run, and with the cooperation of the gears, the rotating arm rotates. At the same time, high-pressure gas is delivered through the high-pressure air tank, so that the blow-jet pipe sprays high-pressure gas evenly onto the inner surface of the filter bag during the rotation process, thereby blowing away the dust on the surface of the filter bag and ensuring the filtration efficiency of the filter bag.

[0004] However, during the current use of the jet cleaning device, the pressure of the compressed air is too high, causing other equipment to be damaged due to the inability to withstand the excessive pressure. At the same time, during the operation of the gears, individual fixing pins may gradually loosen, affecting the meshing accuracy between the gears, which in turn reduces the cleaning quality and safety of the device.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0036] Example 1:

[0037] Please see Figure 1 - Figure 3 This is the first embodiment of the present invention.

[0038] This embodiment provides a pulse rotary jetting device, including: a housing 1, a reducer 2, a servo motor 3, an air pump 5, and a conduit 6; the reducer 2 is fixed to the top side of the housing 1, the output end of the servo motor 3 is fixedly connected to the input end of the reducer 2, the air pump 5 is fixed to the bottom side of the housing 1, and the conduit 6 is fixed to the output end of the air pump 5. It also includes:

[0039] Safety component 4, air supply component 7, connecting component 8 and transmission component 9; safety component 4 is located on the side of housing 1, air supply component 7 is located on the top side of safety component 4, connecting component 8 is located on the top inner side of housing 1, and transmission component 9 is located at the bottom output end of reducer 2.

[0040] Specifically, safety component 4 includes a gas tank 41, a cylinder 42, a top plate 43, a rubber plug 44, an air hole 45, a lifting plate 46, a spring 47, a connecting seat 48, a hollow threaded rod 49, and a turntable 491. The gas tank 41 is fixed to the side of the housing 1. One end of the conduit 6 is connected to the inside of the gas tank 41. The bottom of the gas tank 41 is fixed to the cylinder 42. The top of the cylinder 42 is slidably installed on the top of the inside of the cylinder 42. A rubber plug 44 is fixed to the top side of the top plate 43. Air holes 45 are evenly opened at the edge of the surface of the top plate 43. The lifting plate 46 is slidably installed on the bottom of the inside of the cylinder 42. A spring 47 is fixedly connected between the lifting plate 46 and the top plate 43. The bottom of the lifting plate 46 is rotatably connected to the hollow threaded rod 49 through the connecting seat 48. The bottom of the hollow threaded rod 49 passes through the cylinder 42 and is fixed to the turntable 491. The hollow threaded rod 49 is rotatably connected to the cylinder 42.

[0041] Furthermore, by cooperating with the top plate 43, the spring 47 can automatically discharge air when the pressure inside the air tank 41 is too high, thus preventing damage to other equipment when high-pressure air is delivered.

[0042] Specifically, the gas delivery assembly 7 includes an output pipe 71, a pressure reducing valve 72, and a gas delivery pipe 73. The output pipe 71 is fixed to the top side of the gas tank 41 and is connected to the top of the inner side of the gas tank 41. A pressure reducing valve 72 is fixedly installed at one end of the output pipe 71 and is fixed to the top side of the housing 1. The gas delivery pipe 73 is fixed to the output end of the pressure reducing valve 72.

[0043] Furthermore, high-pressure air is discharged through the output pipe 71 on the top side of the gas tank 41. At this time, the pressure reducing valve 72 adjusts the pressure of the air inside the output pipe 71 so that the gas supply pipe 73 can output air within a suitable range and with stable pressure to prevent damage to other equipment.

[0044] During use, the air pump 5 delivers air to the inside of the air tank 41 through the conduit 6. If the pressure inside the air tank 41 is too high, it will push the top plate 43 to slide downward inside the cylinder 42, causing the rubber stopper 44 to disengage from the opening. At this time, the air inside the air tank 41 passes through the air hole 45 and is discharged from the bottom of the hollow threaded rod 49. When the pressure inside the air tank 41 is normal, the spring 47 pushes the top plate 43 to reset through its elastic force, sealing the bottom of the air tank 41. During use, the turntable 491 can be rotated to drive the hollow threaded rod 49 to rotate, thereby changing the distance between the top plate 43 and the lifting plate 46, changing the compression length of the spring 47, and thus changing the pressure when the air tank 41 releases air. At the same time, the air tank 41 discharges high-pressure air through its top output pipe 71. At this time, the pressure reducing valve 72 adjusts the pressure of the air inside the output pipe 71, so that the air supply pipe 73 can output air with a stable pressure, making the device more flexible and convenient to use.

[0045] In summary, through the structure of safety component 4 and gas delivery component 7, when the pressure inside gas tank 41 is too high, it will push the top plate 43 to slide downward inside the cylinder 42, causing the rubber plug 44 to disengage from the opening, so that the air inside gas tank 41 can be discharged through the air hole 45 from the bottom end of the hollow threaded rod 49. This ensures that the pressure inside gas tank 41 is within a safe range, preventing other equipment from being damaged due to excessive pressure during gas delivery, while also improving the safety of the device during use.

[0046] Example 2:

[0047] Please see Figure 4 - Figure 5 This is the second embodiment of the present utility model.

[0048] Specifically, the connecting assembly 8 includes a hollow shaft 81, a limiting block 82, a limiting groove 83, a support rod 84, a jet pipe 85, a connecting rod 86, a cavity 87, and a jet nozzle 88. The hollow shaft 81 is inserted and installed at the top of the inner side of the housing 1. The hollow shaft 81 is rotatably installed in the limiting groove 83 inside the housing 1 through the limiting block 82. The top of the hollow shaft 81 is fixedly connected to one end of the air supply pipe 73. The bottom end of the hollow shaft 81 is fixed with a support rod 84. The two ends of the inner side of the support rod 84 are symmetrically fixed with jet pipes 85. The center of the inner side of the support rod 84 is fixed with a connecting rod 86. The inner side of the support rod 84 has a cavity 87. The jet pipe 85 has jet nozzles 88 evenly distributed on its circumference. The jet pipe 85 communicates with the inner side of the cavity 87.

[0049] Furthermore, through the hollow shaft 81, while driving the support rod 84 and the jet pipe 85 to rotate, high-pressure air can also be delivered to its inner side, so that it can be evenly sprayed onto the surface of the filter bag from the jet nozzle 88 to remove dust and impurities from the surface of the filter bag.

[0050] Specifically, the transmission assembly 9 includes an output shaft 91, a bushing 92, a step 93, a drive gear 94, and a transmission gear 95. The output shaft 91 is fixed to the output end of the reducer 2. The bushing 92 is installed at the bottom end of the output shaft 91. The step 93 is provided on the top side of the bushing 92. The step 93 is fixedly connected to the drive gear 94 by symmetrically arranged fixing pins. The transmission gear 95 is provided on one side of the drive gear 94. The transmission gear 95 is fixed on the hollow shaft 81 by a fixing pin. The drive gear 94 and the transmission gear 95 mesh with each other.

[0051] Furthermore, the output shaft 91 is fixedly connected to the gear by the bushing 92 and the symmetrically arranged fixing pins, so that when transmitting power, the load is distributed on the two fixing pins, preventing the fixing pins from loosening due to vibration during use and improving the gear meshing accuracy.

[0052] In use, the servo motor 3 is controlled to reduce the speed of its output end by the reducer 2, which then drives the output shaft 91 to rotate. At this time, with the cooperation of the fixed pin and the bushing 92, the drive gear 94 can be driven to rotate. With the cooperation of the transmission gear 95, the hollow shaft 81 is driven to rotate, thereby causing the jet pipe 85 on its bottom side to rotate around the connecting rod 86. At this time, high-pressure air can be delivered to the inside of the hollow shaft 81, which passes through the cavity 87 and the jet pipe 85, and the air is sprayed out from the jet port 88, thereby removing the dust on the surface of the filter bag. Through the fixed pin and bushing 92 and other structures, gear friction can be reduced, the meshing position of the directional gear can be offset, thereby extending the service life of the device.

[0053] In summary, through the structure of connecting component 8 and transmission component 9, hollow shaft 81 is rotatably connected to housing 1 with the cooperation of limiting block 82 and limiting groove 83. At this time, the reducer 2 at the output end of servo motor 3 can drive hollow shaft 81 to rotate. While performing pulse rotation spraying, it can reduce wear at gear connection and extend service life.
