Abstract
Description
Technical Field
[0001] This utility model relates to the field of purification equipment technology, specifically to a waste gas purification device. Background Technology
[0002] Industrial production often involves devices that generate exhaust gases, such as generator sets. These exhaust gases contain a large number of particles, necessitating filtration. Existing exhaust gas purification devices typically utilize filter cartridges, but these require regular maintenance and replacement. Maintenance necessitates stopping the system, yet a significant amount of exhaust gas remains in the ductwork, leading to continued leakage even during maintenance. Therefore, a more convenient exhaust gas purification device that allows for easy filter cartridge maintenance is needed. Utility Model Content
[0003] The technical problem solved by this utility model is to provide a waste gas purification device to solve the problems mentioned in the background art.
[0004] The technical problem solved by this utility model is achieved by the following technical solution: A waste gas purification device includes a purification chamber, which contains an air inlet chamber, an equipment chamber, and an exhaust chamber arranged sequentially. An air inlet pipe is provided on one side of the air inlet chamber and is connected to an external waste gas pipeline through the air inlet pipe. Two equipment chambers are provided and separated by a partition. An air guide hole is provided at the upper end of the equipment chamber and is connected to the air inlet chamber through the air guide hole. A filter element is detachably installed at the lower end of the air guide hole to filter the introduced waste gas. An adjustment component is provided on the purification chamber to close the corresponding air guide hole so as to switch the connection between the air inlet chamber and different equipment chambers. A one-way valve is provided at the lower end of the equipment chamber and is connected to the exhaust chamber to introduce the filtered gas into the exhaust chamber. An exhaust pipe is provided on one side of the exhaust chamber to connect to an external pipeline through the exhaust pipe.
[0005] As a further embodiment of this utility model:
[0006] A shelf is provided between the air inlet chamber and the equipment chamber. Air guide holes are opened on the shelf. A locking block is arranged in a ring around the air guide hole at the lower end of the shelf. A locking groove is provided between the locking block and the shelf. A locking plate is arranged in a ring on the outer side of the upper end of the filter element. Personnel can rotate the locking plate and lock it into the locking groove, thereby installing the filter element at the lower end of the shelf.
[0007] As a further embodiment of this utility model:
[0008] The shelf has an annular stepped plate on the outer side of the upper end of the air vent. The stepped plate has a trapezoidal groove. The adjustment assembly includes a pressure plate abutting against the upper end of the stepped plate and an adjustment shaft for controlling the lifting and lowering of the pressure plate. The upper end of the pressure plate is fixedly connected to the adjustment shaft through a support plate. The middle part of the shelf has a spring-loaded sleeve connected to the adjustment shaft. The adjustment shaft is slidably installed in the spring-loaded sleeve, and the upper end of the adjustment shaft passes through the corresponding bushing of the purification chamber. A handle is fixedly installed on the outer end of the adjustment shaft of the purification chamber so that personnel can rotate the pressure plate by rotating the handle to insert the pressure plate into different trapezoidal grooves, thereby switching the connection between the air intake chamber and different equipment chambers.
[0009] As a further embodiment of this utility model:
[0010] The adjusting shaft is located inside the spring-loaded sleeve and has a spring plate. An annular plate is located at the upper end of the spring-loaded sleeve. A downward-pressing spring, sleeved on the outer end of the adjusting shaft, is located between the annular plate and the spring plate to push the adjusting shaft downwards. Specifically, when the operator rotates the pressure plate to the upper end of the corresponding air vent, the seal between the pressure plate and the stepped plate is unstable due to the pressure plate's own weight. By applying downward pressure through the downward-pressing spring, the pressure plate and the stepped plate can be tightly fitted, improving the stability of the seal.
[0011] As a further embodiment of this utility model:
[0012] The equipment chamber is equipped with an openable sliding door on the outside. The sliding door is slidably installed in the corresponding groove of the purification box. The outer end of the sliding door is equipped with a push handle to facilitate personnel to push it, thereby making it easy for personnel to open the equipment chamber to replace the filter element.
[0013] As a further embodiment of this utility model:
[0014] The purification chamber has a positioning plate on one side that works with the sliding door. The positioning plate has a strip hole, and the corresponding position of the sliding door has a corresponding screw hole. The sliding door is fixedly connected to the positioning plate by bolts to increase the stability and sealing of the sliding door installation.
[0015] Compared with existing technologies, the advantages of this invention are as follows: Exhaust gas is introduced into the intake chamber through the intake pipe. Personnel can adjust the position of the pressure plate by rotating the handle, causing the pressure plate to engage with the upper end of the corresponding air guide hole and seal against the stepped plate, thus closing the ventilation of the corresponding equipment chamber. Exhaust gas then enters the corresponding equipment chamber through another set of air guide holes. Personnel can then open the sliding door to maintain the filter element in the sealed equipment chamber, without affecting normal work progress. Furthermore, because the upper air guide hole of the corresponding equipment chamber is closed by the pressure plate, and the one-way valve at the lower end of the equipment chamber prevents gas from entering the exhaust chamber, exhaust gas leakage during filter element maintenance and replacement is reduced, improving safety during maintenance. This device switches the intake chamber to connect with different equipment chambers for air supply and can close unused equipment chambers, facilitating the disassembly and maintenance of the filter element. The filter element is rotated and secured into the slot by the clamping plate; personnel can also rotate the plate to disengage it from the slot, thus enabling quick filter element replacement.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.
[0021] like Figures 1-3 As shown,
[0022] This embodiment provides a waste gas purification device, including a purification chamber 1. The purification chamber 1 is provided with an air inlet chamber 11, an equipment chamber 12, and an exhaust chamber 13 in sequence. An air inlet pipe 14 is provided on one side of the air inlet chamber 11 and is connected to an external waste gas pipeline through the air inlet pipe 14. There are two equipment chambers 12, which are separated by a partition 15. The upper end of the equipment chamber 12 is provided with an air guide hole 16, which is connected to the air inlet chamber 11 through the air guide hole 16. A filter element 2 is detachably installed at the lower end of the air guide hole 16 to filter the introduced waste gas. The purification chamber 1 is provided with an adjustment component that closes the corresponding air guide hole 16 to switch the connection between the air inlet chamber 11 and different equipment chambers 12. The lower end of the equipment chamber 12 is provided with a one-way valve 17 connected to the exhaust chamber 13 to introduce the filtered gas into the exhaust chamber 13. An exhaust pipe 18 is provided on one side of the exhaust chamber 13 to connect to an external pipeline through the exhaust pipe 18.
[0023] In this embodiment, a shelf 19 is provided between the air inlet chamber 11 and the equipment chamber 12. An air guide hole 16 is opened on the shelf 19. A locking block 21 is arranged in a ring around the air guide hole 16 at the lower end of the shelf 19. A locking groove is provided between the locking block 21 and the shelf 19. A locking plate 22 is arranged in a ring on the outer side of the upper end of the filter element 2. Personnel can rotate the locking plate 22 and lock it into the locking groove, thereby installing the filter element 2 at the lower end of the shelf 19.
[0024] In this embodiment, the shelf 19 is provided with an annular stepped plate 23 on the outer side of the upper end of the air guide hole 16. The stepped plate 23 has a trapezoidal groove. The adjustment component includes a pressure plate 31 abutting against the upper end of the stepped plate 23 and an adjustment shaft 3 for controlling the lifting and lowering movement of the pressure plate 31. The upper end of the pressure plate 31 is fixedly connected to the adjustment shaft 3 through a support plate 32. The middle part of the shelf 19 is provided with a spring-loaded sleeve 33 connected to the adjustment shaft 3. The adjustment shaft 3 is slidably installed in the spring-loaded sleeve 33, and the upper end of the adjustment shaft 3 passes through the bushing 34 corresponding to the purification box 1. A handle 35 is fixedly installed on the outer end of the adjustment shaft 3 at the purification box 1 so that personnel can rotate the pressure plate 31 through the handle 35 to insert the pressure plate 31 into different trapezoidal grooves, thereby switching the connection between the air intake chamber 11 and different equipment chambers 12.
[0025] The adjusting shaft 3 is located inside the spring-loaded sleeve 33 and has a spring plate 36. The upper end of the spring-loaded sleeve 33 has an annular plate 37. A downward pressure spring 38 is sleeved on the outer end of the adjusting shaft 3 between the annular plate 37 and the spring plate 36 to push the adjusting shaft 3 downward. Specifically, when the operator rotates the pressure plate 31 to the upper end of the corresponding air guide hole 16, the seal between the pressure plate 31 and the stepped plate 23 is not stable due to its own weight. By applying downward pressure through the downward pressure spring 38, the pressure plate 31 and the stepped plate 23 can be tightly fitted, improving the stability of the seal.
[0026] In this embodiment, the outer side of the equipment chamber 12 is provided with an openable sliding door 4. The sliding door 4 is slidably installed in the corresponding slide groove of the purification box 1. The outer end of the sliding door 4 is provided with a push handle 41 so that personnel can push it, thereby facilitating personnel to open the equipment chamber 12 to replace the filter element 2.
[0027] In this embodiment, a positioning plate 42 is provided on one side of the purification box 1 to cooperate with the sliding door. The positioning plate 42 is provided with a strip hole, and the corresponding position of the sliding door 4 is provided with a corresponding screw hole corresponding to the strip hole. The sliding door 4 is fixedly connected to the positioning plate 42 by bolts 43 to increase the stability and sealing of the installation of the sliding door 4.
[0028] Specifically, exhaust gas is introduced into the intake chamber 11 through the intake pipe 14. Personnel can adjust the position of the pressure plate 31 by rotating the handle 35, causing the pressure plate 31 to engage with the upper end of the corresponding air guide hole 16 and seal against the step plate 23, thus closing the ventilation of the corresponding equipment chamber 12. Exhaust gas then enters the corresponding equipment chamber 12 through another set of air guide holes 16. Personnel can then open the sliding door to maintain the filter element 2 within the sealed equipment chamber 12, without affecting normal work progress. Furthermore, since the upper air guide hole 16 of the corresponding equipment chamber 12 is sealed by the pressure plate 31, and the one-way valve at the lower end of the equipment chamber 12 prevents gas from entering the exhaust chamber 13, exhaust gas leakage during filter element 2 maintenance and replacement can be reduced, improving safety during maintenance. This device facilitates the disassembly and maintenance of the filter element 2 by switching the intake chamber 11 to supply air to different equipment chambers 12 and by sealing off unused equipment chambers 12. The filter element 2 is inserted into the slot by rotating the clamping plate 22. The clamping plate 22 can also be rotated to disengage from the slot, thus completing the quick replacement of the filter element 2.
