Description
Technical Field
[0001] The utility model belongs to the technical field of pulse dust removal, and in particular relates to a pulse dust removal device. Background Art
[0002] The technical background of pulse dust removal equipment is based on bag filter technology, which is a commonly used method in industrial dust control. Its main principle is to use porous bag materials to intercept dust on the outer surface of the bag when the dust-laden gas passes through, thereby achieving gas-solid separation and achieving the purpose of purifying the gas. Pulse jet cleaning technology is a widely used cleaning method in bag dust collectors. It mainly uses periodic high-pressure pulse spraying on the bag to make the dust on the filter bag fall off and fall into the ash hopper, thereby restoring the filtering function of the bag. In existing pulse dust removal equipment, a large amount of dust will fall from the filter bag after pulse spraying. If the dust discharge system is improperly designed or operated improperly, it is indeed easy to cause the dust discharge port to be blocked. This is mainly because the dust discharge system needs to promptly and effectively discharge the dust shaken off during the cleaning process from the dust collector to prevent the dust from entering the airflow again and affecting the dust removal effect. Utility Model Content
[0003] In order to overcome the problem that the dust discharge port of the existing pulse dust removal equipment is easily blocked due to the huge amount of dust after the pulse impact.
[0004] The technical solution of the utility model is: a pulse dust removal device, including a pulse dust removal, and also including a maintenance bin assembly, a pulse pump, and an exhaust fan; a maintenance bin assembly is arranged at the upper end of the pulse dust removal; a pulse pump and an exhaust fan are respectively arranged on both sides of the maintenance bin assembly; the pulse dust removal includes a dust removal bin, a dust removal bag, a dust removal bag frame, and a dust discharge mixer; a dust removal bag is arranged inside the dust removal bin, and the dust discharge mixer stirs the falling dust, which is beneficial to the stirring and discharge of the dust and facilitates the discharge of the dust; a dust discharge mixer is arranged at the lower end of the dust removal bin, and the stirring blades at the output end of the dust discharge mixer are arranged inside the dust removal bin; the upper end pipeline of the dust removal bag is connected to the input end pipeline of the exhaust fan, and the upper end pipeline of the dust removal bag is connected to the output end pipeline of the pulse pump; a dust removal bag frame is arranged around the outer side of the dust removal bag, and the dust removal bag frame is fixedly connected to the dust removal bag, and the dust removal bag frame effectively improves the morphological support performance of the dust removal bag.
[0005] Preferably, exhaust gas is blown into the dust collector from one side through the dust collector bin, and the exhaust gas is sucked by the exhaust fan so that the exhaust gas passes through the dust collector bag for filtration. After the exhaust gas is filtered, the air is discharged from the output end of the exhaust fan. When the dust covers the outer wall of the dust collector bag, the filtration efficiency decreases. At this time, the pulse pump emits a pulse air wave and blows it into the interior of the dust collector bag along the pipeline. The pulse air wave vibrates and blows out the dust on the outer wall of the dust collector bag, so that a large amount of dust falls into the output end of the dust discharge mixer. As the impeller of the dust discharge mixer rotates, the dust is stirred and discharged, which solves the problem of the existing pulse dust removal equipment, because the amount of dust after the pulse impact is huge, causing the dust discharge port to be easily blocked.
[0006] Preferably, an air inlet is provided on one side of the dust removal bin, and the air inlet is arranged on the upper side of the dust discharge mixer, and exhaust gas is blown into the dust removal bin from one side. The exhaust gas passes through the dust bag for filtration due to the suction of the exhaust fan. After the exhaust gas is filtered, the air is discharged from the output end of the exhaust fan. When the dust covers the outer wall of the dust bag, the filtration efficiency decreases. At this time, the pulse pump emits a pulse air wave and blows it into the interior of the dust bag along the pipeline. The pulse air wave vibrates and blows out the dust on the outer wall of the dust bag, so that a large amount of dust falls into the output end of the dust discharge mixer, and the dust is stirred and discharged as the impeller of the dust discharge mixer rotates; this solves the problem of the existing pulse dust removal equipment, because the amount of dust after the pulse impact is huge, causing the dust discharge port to be easily blocked.
[0007] Preferably, the maintenance bin assembly includes a maintenance bin and a maintenance sealing cover; a maintenance sealing cover is provided at the upper end of the maintenance bin, and the maintenance sealing cover is hingedly connected to the maintenance bin, and the maintenance sealing cover facilitates maintenance and installation operations above the dust bag.
[0008] Beneficial effects of the utility model:
[0009] 1. The existing pulse dust removal equipment has a huge amount of dust after the pulse impact, which causes the dust discharge port to be easily blocked. The exhaust gas is blown into the dust removal bin from one side. The exhaust gas passes through the dust removal bag for filtration due to the exhaust of the exhaust fan. After the exhaust gas is filtered, the air is discharged from the output end of the exhaust fan. When the dust covers the outer wall of the dust removal bag, the filtration efficiency decreases. At this time, the pulse pump sends a pulse air wave along the pipeline to blow into the inside of the dust removal bag. The pulse air wave vibrates and blows out the dust on the outer wall of the dust removal bag, so that a large amount of dust falls into the output end of the dust discharge mixer. As the impeller of the dust discharge mixer rotates, the dust is stirred and discharged. This solves the problem that the dust discharge port of the existing pulse dust removal equipment is easily blocked due to the huge amount of dust after the pulse impact.
[0010] 2. Through the setting of the dust discharge mixer, the dust discharge mixer stirs the falling dust, which is conducive to the stirring and discharge of the dust and facilitates the discharge of the dust. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0017] See also Figure 1-4 The utility model provides an embodiment: a pulse dust removal device, including a pulse dust collector 1, and also including a maintenance bin assembly 2, a pulse pump 3, and an exhaust fan 4; the upper end of the pulse dust collector 1 is provided with the maintenance bin assembly 2; the pulse pump 3 and the exhaust fan 4 are respectively provided on both sides of the maintenance bin assembly 2.
[0018] See also Figure 1-4 In this embodiment, the pulse dust collector 1 includes a dust removal bin 101, a dust removal bag 102, a dust removal bag frame 103, and a dust discharge mixer 104; the dust removal bag 102 is arranged inside the dust removal bin 101, the dust removal bin 101 is provided with a dust discharge mixer 104 at the lower end, and the output end stirring blade of the dust discharge mixer 104 is arranged inside the dust removal bin 101, the upper end pipeline of the dust removal bag 102 is connected to the input end pipeline of the exhaust fan 4, and the upper end pipeline of the dust removal bag 102 is connected to the input end pipeline of the exhaust fan 4. The output end pipeline of the pulse pump 3 is connected, a dust bag frame 103 is arranged on the outer side of the dust bag 102, and the dust bag frame 103 is fixedly connected to the dust bag 102, an air inlet is arranged on one side of the dust removal bin 101, and the air inlet is arranged on the upper side of the dust discharge mixer 104, and the maintenance bin assembly 2 includes a maintenance bin 201 and a maintenance sealing cover 202; a maintenance sealing cover 202 is arranged on the upper end of the maintenance bin 201, and the maintenance sealing cover 202 is hingedly connected to the maintenance bin 201.
[0019] During operation, exhaust gas is blown in from one side through the dust removal bin 101. The exhaust gas is extracted by the exhaust fan 4 so that the exhaust gas passes through the dust bag 102 for filtration. After the exhaust gas is filtered, the air is discharged from the output end of the exhaust fan 4. When the dust covers the outer wall of the dust bag 102, the filtration efficiency decreases. At this time, the pulse pump 3 emits a pulse air wave and blows it into the interior of the dust bag 102 along the pipeline. The pulse air wave vibrates and blows out the dust on the outer wall of the dust bag 102, so that a large amount of dust falls into the output end of the dust discharge mixer 104. As the impeller of the dust discharge mixer 104 rotates, the dust is stirred and discharged. This solves the problem of the existing pulse dust removal equipment, because the amount of dust after the pulse impact is huge, causing the dust discharge port to be easily blocked.
[0020] Next, the dust discharge mixer 104 stirs the falling dust, thereby facilitating the stirring and discharge of the dust and facilitating the discharge of the dust.
[0021] Through the above steps, exhaust gas is blown into the dust removal bin 101 from one side, and the exhaust gas is exhausted through the dust bag 102 for filtration due to the exhaust of the exhaust fan 4. After the exhaust gas is filtered, the air is discharged from the output end of the exhaust fan 4. When the dust covers the outer wall of the dust bag 102, the filtration efficiency decreases. At this time, the pulse pump 3 emits a pulse air wave and blows it into the interior of the dust bag 102 along the pipeline. The pulse air wave vibrates and blows out the dust on the outer wall of the dust bag 102, so that a large amount of dust falls into the output end of the dust discharge mixer 104. As the impeller of the dust discharge mixer 104 rotates, the dust is stirred and discharged, avoiding the problem of the existing pulse dust removal equipment, because the amount of dust after the pulse impact is huge, causing the dust discharge port to be easily blocked.
