Description

Technical Field

[0001] This utility model relates to the field of oil fume purification technology, specifically to an oil fume purifier with low-altitude emissions. Background Technology

[0002] Metal processing generates a large amount of waste gas. Due to operations such as spraying or lubrication during metal production, the waste gas contains a large amount of oil, forming oil fumes. To ensure that the oil fumes are discharged in compliance with emission requirements, a low-altitude emission oil fume purifier is needed to purify the oil fumes generated during metal processing before discharge. The low-altitude emission oil fume purifier is equipped with an oil filter screen. The oil filter screen initially removes a large amount of oil particles from the oil fumes. Therefore, the oil filter screen is more prone to clogging than other components and needs to be replaced and cleaned later. However, the existing oil filter screen is not easy to disassemble and requires the entire machine to be disassembled for replacement, which is very inconvenient and has low replacement efficiency.

Detailed Implementation

[0019] The technical solution of this utility model is described in further detail below with reference to the accompanying drawings, but the scope of protection of this utility model is not limited to the following description.

[0020] like Figure 1 and Figure 2 As shown, a low-altitude emission fume purifier includes a purification chamber 1. A smoke extraction pipe 2 and an exhaust pipe 3 are respectively installed at both ends of the purification chamber 1. An oil filtration mechanism is installed inside the purification chamber 1, comprising a hollow rectangular plate 4 and an oil filter screen 5. The oil filter screen 5 is installed inside the hollow rectangular plate 4. A rectangular mounting groove 6 is provided at the top of the purification chamber 1. The hollow rectangular plate 4 passes through the rectangular mounting groove 6 and is installed inside the purification chamber 1. Locking posts 7 are provided on both sides of the top of the hollow rectangular plate 4. Locking holes 8 are provided on the side walls of the rectangular mounting groove 6 corresponding to the positions of the locking posts 7. The locking posts 7 have the freedom to move axially along the locking holes 8. When the hollow rectangular plate 4 is installed inside the purification chamber 1, one end of the locking post 7 is fitted into the locking hole 8. The inner bottom wall of the purification chamber 1... A positioning groove 18 is provided, and the bottom of the hollow rectangular plate 4 is fitted into the positioning groove 18. The hollow rectangular plate 4 is inserted into the purification box 1 through the rectangular mounting groove 6, so that the bottom of the hollow rectangular plate 4 is inserted into the positioning groove 18, thus completing the positioning of the hollow rectangular plate 4. At this time, the locking hole 8 is located on the moving path of the locking pin 7. Then, the locking pin 7 is moved so that one end of the locking pin 7 is inserted into the locking hole 8. The oil filter mechanism is installed by the cooperation of the locking pin 7 and the locking hole 8. When disassembling, the locking pin 7 is moved to disengage from the locking hole 8. A handle is fixed on the top of the hollow rectangular plate 4. The oil filter mechanism can be disassembled by lifting the hollow rectangular plate 4 with the handle. The oil filter mechanism is installed by plugging and unplugging, which is convenient for replacement and cleaning, and improves the efficiency and difficulty of later maintenance.

[0021] Furthermore, such as Figure 1As shown, two sets of anode plates 19 are arranged vertically opposite each other inside the purification chamber 1. The anode plates 19 are located between the oil filtration mechanism and the exhaust pipe 3. A cathode plate 20 is vertically installed inside the purification chamber 1, located between the anode plates 19 and the exhaust pipe 3. The preliminarily filtered oil fumes enter between the two sets of anode plates 19. Positively charged ions between the anode plates 19 collide with oil particles and other dust particles, causing them to adsorb positive charges. Under the action of the electric field, the charged dust particles also move towards the cathode plate 20. After reaching the cathode, they release the electrons they carry, and the dust particles are deposited on the cathode plate 20, completing the adsorption of oil fumes.

[0022] Furthermore, an oil collection trough 21 is provided on the inner bottom wall of the purification chamber 1, and an oil guide plate 22 is inclinedly arranged below the cathode plate 20. The lower end of the oil guide plate 22 is located directly above the oil collection trough 21. An oil drain pipe 23 is connected to the bottom of the purification chamber 1. The oil drain pipe 23 is connected to the oil collection trough 21. An electromagnetic valve is provided on the oil drain pipe 23. The oil adsorbed on the cathode plate 20 falls onto the oil guide plate 22. Through the guiding action of the oil guide plate 22, the oil falls into the oil collection trough 21 for collection. The oil is discharged at a specified time and discharged to a designated location through the oil drain pipe 23.

[0023] Furthermore, such as Figure 1 and Figure 2 As shown, the hollow rectangular plate 4 has an installation groove 9 at the position where the locking pin 7 is located. The locking pin 7 is slidably disposed in the installation groove 9. A spring 10 is installed in the installation groove 9, and the two ends of the spring 10 are connected to the hollow rectangular plate 4 and the locking pin 7 respectively. A strip groove 11 is opened on the top surface of the hollow rectangular plate 4, and the strip groove 11 connects to the installation groove 9. A toggle rod 12 is fixed to the top of the locking pin 7, and the top end of the toggle rod 12 extends out of the strip groove 11. During installation, the toggle rod 12 is moved away from the lock hole 8, so that the toggle rod 12 drives the locking pin 7 to move into the installation groove 9, so that the locking pin 7 is completely located in the installation groove. Then, after the hollow rectangular plate 4 is installed in place, the toggle rod 12 is released, and the locking pin 7 is inserted into the lock hole 8 under the reaction force of the spring 10, thus completing the limiting installation of the oil filter mechanism. During disassembly, the locking pin 7 is disengaged from the lock hole 8 by the toggle rod 12, and finally the hollow rectangular plate 4 is taken out upwards. The operation is simple and quick.

[0024] Furthermore, such as Figure 2As shown, a rectangular sealing groove 13 is formed around the rectangular mounting groove 6 on the top of the purification chamber 1. The rectangular sealing groove 13 connects to the rectangular mounting groove 6. A hollow sealing gasket 14 is fixed inside the rectangular sealing groove 13. A hollow rectangular plate 4 passes through the inner hole of the hollow sealing gasket 14. A hollow sealing plate 15 is installed on the top of the purification chamber 1. The hollow sealing plate 15 compresses and deforms the hollow sealing gasket 14 to make the hollow sealing gasket 14 fit tightly against the outer wall of the hollow rectangular plate 4. The hollow sealing plate 15 has a large-size plate 16 and a small-size plate 17. The small-size plate 17 is concentrically fixed to the bottom of the large-size plate 16. The large-size plate 16 is installed on the purification chamber 1 by screws. The small-size plate 17 extends into the rectangular sealing groove 13 to compress the hollow sealing gasket 14. To avoid Oil fumes overflow through the gap between the hollow rectangular plate 4 and the rectangular mounting groove 6. A hollow sealing gasket 14 is provided. Under normal conditions, the hollow sealing gasket 14 and the hollow rectangular plate 4 are in a clearance fit. After the hollow rectangular plate 4 is installed in place, the hollow sealing plate 15 is installed. When the large-size plate 16 is fixed to the purification box 1 with screws, the small-size plate 17 will extend into the rectangular sealing groove 13. The small-size plate 17 will compress the hollow sealing gasket 14 and cause it to deform. The hollow sealing gasket 14 becomes thinner under compression, but its length will increase, so that the hollow sealing gasket 14 presses against the outer wall of the hollow rectangular plate 4 to form a high-strength sealing surface. This allows the oil filtration mechanism to be detachably installed while ensuring sealing performance and preventing oil fume overflow.
