Description

Technical Field

[0001] This utility model relates to the field of waste gas filtration technology, and in particular to a waste gas filtration device. Background Technology

[0002] Exhaust gas filtration devices typically use filter screens or filter bags to filter exhaust gas, intercepting and filtering large particulate impurities. After prolonged operation, a significant amount of impurities will accumulate on the filter screen or inside the filter bag, affecting its filtration efficiency. In this case, the filter screen or filter bag needs to be cleaned or replaced to maintain filtration efficiency.

[0003] In existing technologies, replacement must be completed outside of working hours, and maintenance time for staff often needs to be scheduled after normal working hours, thus extending working hours. Therefore, it is essential to improve the exhaust gas filter device so that it can be replaced and maintained during normal working hours without affecting normal production. Utility Model Content

[0006] Preferably, a collection box is slidably disposed at the bottom of the air intake chamber.

[0007] Preferably, the through hole has a T-shaped cross-section, and the partition plate has multiple limiting holes located around the circumference of the through hole. The plug has a limiting rod that passes through the limiting holes, and a spring is sleeved on the limiting rod. The spring pushes the plug so that the plug enters the through hole.

[0008] Preferably, the plug has a T-shaped structure, an air passage is provided inside the plug, and multiple air holes are opened around the circumference of the plug to connect the air passage. When the plug is located in the through hole, the air holes are blocked.

[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0018] Depend on Figures 1 to 6 It is known that a waste gas filtration device includes a housing 1, which is divided into an air inlet chamber 3 and a filter chamber 4 by a partition 2. An air inlet pipe 5 communicating with the air inlet chamber 3 and an air outlet pipe 6 communicating with the filter chamber 4 are provided outside the housing 1. Multiple through holes 7 are provided on the partition 2, and plugs 8 are slidably provided at the through holes 7. After the filter bag 9 is inserted from the end of the housing 1, the plugs 8 are pushed open, so that the air inlet chamber 3 is connected to the inside of the filter bag 9. The waste gas is filtered by the filter bag 9 and discharged from the air outlet pipe 6.

[0019] In practical use, this utility model

[0020] This device is installed in the waste gas treatment system. The waste gas enters the housing 1 through the inlet pipe 5, passes through the partition 2 and enters the filter bag 9. After being filtered by the filter bag 9, the waste gas is discharged through the outlet pipe 6.

[0021] When the filter bag 9 needs to be replaced, simply pull the filter bag 9 out from the end of the housing 1. The plug 8 will block the through hole 7 at that point. Filtering will then proceed through the other through holes 7 into the filter bag 9 without affecting normal production. The new filter bag 9 can be directly inserted into the housing 1. The end of the filter bag 9 will push open the plug 8, allowing the air inlet chamber 3 to reconnect with the inside of the filter bag 9.

[0022] The filter bag 9 is fixed to the end of the housing 1 with screws, which is convenient to install and remove and has strong stability.

[0023] A collection box 10 is slidably installed at the bottom of the air intake chamber 3. The collection box 10 can collect waste that falls from the filter bag 9. The collection box 10 can be cleaned after a period of time.

[0024] The through hole 7 has a T-shaped cross-section. The partition plate 2 has multiple limiting holes 11 located around the circumference of the through hole 7. The plug 8 has a limiting rod 12 that passes through the limiting holes 11. A spring 13 is sleeved on the limiting rod 12. The spring 13 pushes the plug 8 so that the plug 8 enters the through hole 7. The plug 8 has a T-shaped structure. The plug 8 has an air passage 14 inside. The circumference of the plug 8 has multiple air holes 15 that connect to the air passage 14. When the plug 8 is inside the through hole 7, the air holes 15 are blocked.

[0025] Without the filter bag 9 installed, the spring 13 pushes the limiting rod 12, causing the plug 8 to enter the through hole 7, blocking the air hole 15. This completely seals the through hole 7, preventing exhaust gas from entering the filter chamber 4 through the partition 2 and instead allowing it to exit through the outlet pipe 6. When the filter bag 9 is installed, the inner end of the filter bag 9 pushes the plug 8, causing it to move towards the air inlet chamber 3. The air hole 15 extends out of the partition 2, allowing exhaust gas to enter the filter bag 9 through the air hole 15 and the air passage 14, thus completing the filtration.

[0026] The length of the filter bag 9 is adapted to the length of the filter chamber 4, and the plug 8 can be pushed open to allow the air hole 15 to extend outside the partition 2, so that the air inlet chamber 3 can be connected to the inside of the filter bag 9.

[0027] The filter chamber 4 is provided with a bracket 16 located around the through hole 7. The bracket 16 supports the filter bag 9, allowing the inner end of the filter bag 9 to smoothly contact the plug 8. After the filter bag 9 is pushed, the inner end of the filter bag 9 is limited at the through hole 7, which improves stability and sealing and prevents the exhaust gas from being discharged without filtration.

[0028] Compared with the prior art, this utility model has the following advantages: by setting baffles and plugs, the filter bags can be replaced under normal working conditions without affecting the normal production process, and will not cause unfiltered exhaust gas to be discharged, thus maintaining filtration efficiency while ensuring the effect of exhaust gas treatment.
