[0002] In the industrial production process, especially in the links involving material transportation and processing, such as the guide trough of the belt conveyor, a large amount of dusty gas is often generated. These dusty gases not only affect the working environment and endanger the health of workers, but may also cause wear and blockage of production equipment and reduce production efficiency. Therefore, effectively treating these dusty gases and realizing dust collection and purification are of great significance to ensure production safety, improve production efficiency and protect the environment.

[0003] Traditional dust treatment methods mostly use natural sedimentation or simple filtering devices, but these methods have many shortcomings in terms of treatment efficiency, purification effect and maintenance cost. The natural sedimentation method is not effective in removing fine dust, and simple filtering devices are prone to clogging, requiring frequent replacement of filter materials, which increases operating costs. Summary of the invention

[0004] The purpose of the present invention is to provide a double-ring horizontal explosion-proof pulse filter bag dust collector, which solves the problems of poor processing efficiency, purification effect and removal effect of traditional dust removal equipment.

[0012] The double-ring horizontal explosion-proof pulse filter bag dust collector of the present invention, when in use, the air inside the main body is sucked out by the fan, so that a negative pressure is formed inside the inspection room. At this time, the air inlet at the bottom of the main body sucks in air, and then enters the main body through the connector, wherein coarse particles of dust directly sink into the belt conveyor guide chute due to the reduced wind speed, and fine dust enters the bag chamber with the air flow, and after being filtered by the filter bag, a dust layer is formed and adheres to the outer wall of the filter bag, and the purified gas enters the clean air chamber and is discharged through the fan; as the filtering time increases, more and more dust is accumulated on the outside of the filter bag, increasing the filtering time. The resistance of the bag causes the processed air volume to gradually decrease. For normal operation, the resistance must be controlled within a certain range (1200-1500Pa). The filter bag needs to be cleaned. During cleaning, the blowing component blows air into the inside of the filter bag through an opening on one side of the filter bag, causing the filter bag to expand sharply and instantly, and the dust layer accumulated on the surface of the filter bag falls off.

Figure 4 It is a top view of a double-ring horizontal explosion-proof pulse filter bag dust collector.

[0023] The present invention provides a double-ring horizontal explosion-proof pulse filter bag dust collector, comprising a main body 101 and a dust removal assembly 102, wherein the dust removal assembly 102 comprises a connector 103, a fan 104, two mounting plates 105, a filter bag 106, an explosion-proof door 107 and a blowing component 108, wherein the blowing component 108 comprises a blowing pipe 109, an air bag 110, a pulse valve 111 and a fixing component 112, wherein the filter bag 106 comprises a filter bag cage 113, a bag body 114 and a sealing end cover 115, wherein the filter bag cage 113 comprises a support ring 116, a connecting rod 117 and mounting seat 118, the dust-containing gas is filtered through the filter bag 106. When a large amount of dust adheres to the surface of the filter bag 106 and the filtering effect is reduced, the blowing component 108 is started to blow air toward the opening on one side of the filter bag 106, thereby expanding the filter bag 106, so that the dust on the surface of the filter bag 106 falls off and falls onto the belt conveyor through the connector 103 for transportation. It can be understood that the above scheme can be used to improve the filtering effect of dust-containing gas, and can also be used to avoid damage to the filter bag 106 and affect its use.

[0024] According to this specific implementation, the main body 101 is arranged above the material guide chute of the belt conveyor, and an air inlet is arranged at the bottom of the main body 101.

[0025] The main body 101 has a clean air chamber 119 and an inspection chamber 120. The connector 103 is fixedly connected to the main body 101, communicates with the main body 101, and is located at the bottom of the main body 101. The two mounting plates 105 are fixedly connected to the main body 101 and are located inside the main body 101. The two ends of the filter bag 106 are respectively fixedly connected to the two mounting plates 105 and are located between the two mounting plates 105. The explosion-proof door 107 is rotatably installed on the top of the main body 101. The blowing component 108 is arranged on one side of the main body 101 close to the clean air chamber 119; an opening is arranged on one side of the filter bag 106. The inspection chamber 120 is between the two mounting plates 105 for installing the filter bag 106. Bag 106, one side of the main body 101 close to the opening of the filter bag 106 is a clean air chamber 119, a plurality of the filter bags 106 are provided, and the plurality of the filter bags 106 are divided into a plurality of groups and arranged in parallel between the two mounting plates 105, and a certain distance is maintained between each group of the filter bags 106 to ensure uniform distribution of airflow and facilitate maintenance and replacement, and the opening of each group of the filter bags 106 faces the clean air chamber 119, and the connector 103 is conical, which is convenient for discharging dust and allowing the dust to fall on the belt conveyor and be transported away, and the fan 104 is an explosion-proof fan and is arranged on one side of the main body 101 close to the clean air chamber 119, and the explosion-proof door 107 is opened to facilitate the inspection and maintenance of the filter bag 106 inside the main body.

[0026] When in use, the air inside the main body 101 is extracted through the fan 104, so that a negative pressure is formed inside the inspection room 120. At this time, the air inlet at the bottom of the main body 101 sucks in air, and the air enters the main body 101 through the connector 103. The coarse dust particles directly sink into the belt conveyor guide chute due to the reduced wind speed, and the fine dust enters the bag chamber with the air flow. After being filtered by the filter bag 106, a dust layer is formed and attached to the outer wall of the filter bag 106. The purified gas enters the clean air chamber 119 and is discharged through the fan 104. As the filtering time increases, more and more dust is accumulated on the outside of the filter bag 106, which increases the resistance of the filter bag 106, leading to The air volume to be processed is gradually reduced; for normal operation, the resistance must be controlled within a certain range (1200-1500Pa), and the filter bag 106 needs to be cleaned. During cleaning, the blowing component 108 blows air into the inside of the filter bag 106 through an opening on one side of the filter bag 106, causing the filter bag 106 to expand sharply in an instant, and the dust layer accumulated on the surface of the filter bag 106 falls off. At this time, the filter bag 106 recovers its filtering capacity; the fallen dust falls onto the belt conveyor through the connector 103 and is transported away. In this way, the dust accumulated on the filter bag 106 is periodically pulse-blown and cleaned, so that the purified gas passes normally, ensuring the operation of the dust removal system and achieving the purpose of improving the dust removal effect.

[0027] Secondly, the blowing pipe 109 is fixedly connected to the main body 101 and is located inside the main body 101; the pulse valve 111 is installed at one end of the blowing pipe 109; the air bag 110 is installed on the blowing pipe 109; the fixing component 112 is arranged on the main body 101; the fixing component 112 is used to fix the blowing pipe 109, and the blowing components 108 are provided in plurality, corresponding to a plurality of groups of the filter bags 106 respectively. A blowing hole 121 is provided on one side of the blowing pipe 109 close to the opening on the filter bag 106. The pulse controller triggers each control valve in sequence to open the pulse valve 111, and the compressed air in the air bag 110 is instantly ejected at high speed from the blowing hole 121 of the blowing pipe 109 through the pulse valve 111, and at the same time induces the surrounding clean air to enter the filter bag 106, thereby achieving the purpose of blowing.

[0028] At the same time, the two ends of the filter bag cage 113 are fixedly connected to the two mounting plates 105 respectively; the bag body 114 is connected to the filter bag cage 113 and is sleeved on the filter bag cage 113; the bag body 114 is used to filter dust, and the filter bag cage 113 is used to support the bag body 114 to prevent the bag body 114 from folding and affecting the filtering effect.

[0029] In addition, the sealing end cover 115 is fixedly connected to the filter bag cage 113 and is located on a side of the filter bag cage 113 away from the blowing pipe 109; the sealing end cover 115 is used to seal one side of the filter bag 106 to prevent the sprayed airflow from directly blowing toward the bag body 114, causing damage to the bag body 114 and affecting the sealing performance.

[0030] Finally, the two ends of the connecting rod 117 are respectively connected to the two mounting plates 105; the support ring 116 is fixedly connected to the connecting rod 117 and sleeved on the connecting rod 117; the mounting seat 118 is fixedly connected to the connecting rod 117 and fixedly connected to the sealing end cover 115, and is located on one side of the mounting seat 118; there are multiple connecting rods 117, and they are arranged in a circular array on the support ring 116, and there are multiple support rings 116, and the bag body 114 is supported by the support ring 116, and at the same time, the connecting rod 117 is horizontally arranged, and the concentricity of the bag body 114 and the blowing hole 121 on the blowing pipe 109 is guaranteed by the connecting rod 117, thereby reducing the bag breakage caused by side blowing.

[0031] When the double-ring horizontal explosion-proof pulse filter bag dust collector of this embodiment is used, the fan 104 is started to inhale dust-containing gas from the air inlet at the bottom of the main body 101. The gas first passes through the connector 103, where larger dust particles are directly settled on the belt conveyor guide trough due to the reduction in wind speed, thereby achieving preliminary dust separation; then, fine dust enters the inspection room 120 with the air flow, is captured by the filter bag 106, and forms a dust layer attached to the outer wall of the bag body 114, and the purified gas passes through the bag body 114 into the clean air chamber 119, and is finally discharged by the fan 104, thereby ensuring the cleanliness of the exhaust gas; as the filtration progresses, As time goes by, the dust layer on the outside of the filter bag 106 gradually thickens, resulting in an increase in filtration resistance and a decrease in the processed air volume. In order to maintain the normal working state of the dust collector, the filter bag 106 needs to be cleaned regularly. At this time, the pulse controller triggers each control valve in sequence to open the pulse valve 111, and the compressed air in the air bag 110 is ejected at high speed through the pulse valve 111 and the blowing hole 121 on the blowing pipe 109, causing the bag body 114 to expand rapidly and instantly, thereby shaking off the dust layer attached to the surface of the bag body 114; the shaken-off dust falls onto the belt conveyor again through the connector 103 and is transported away together with the initially settled dust.
