Technical Field
[0001] This utility model relates to the technical field of noise reduction mechanisms for oil fume purification devices, and specifically to a noise reduction mechanism for an oil fume purification device. Background Technology
[0002] An oil fume purifier is a device for treating oily fumes and exhaust gases. It is primarily used for purifying and treating low-altitude oily fumes emitted from kitchens; in hotels, restaurants, eateries, schools, government offices, factories, and other similar establishments; in the food frying and cooking processing industry; in oil-splashed heat treatment workshops, oil mist lubrication workshops, workpiece welding workshops, and industrial applications such as oil-fired boiler emissions.
[0003] Currently, patent application CN 220828880 U discloses a noise reduction device for an oil fume purification fan, including an oil fume hood body, a connecting pipe, and a water tank. The connecting pipe is installed on the upper end face of the oil fume hood body, and the water tank is installed on the oil fume hood body. A maintenance structure is provided between the water tank and the connecting pipe. The maintenance structure includes a heating chamber, a heating treatment component, and a rinsing component. The heating chamber in the water tank heats the cleaning water to generate steam, and the internal mesh pressure plate suppresses boiling liquid to prevent overflow at the partition. The steam is then pressurized and fully sprayed into the connecting pipe for rinsing.
[0004] To address the issue of noise reduction mechanisms in oil fume purification devices described above, existing technologies employ a method of heating the cleaning water to generate steam via a heating chamber, which is then used to flush the pipes. However, this approach still presents the problem of the noise reduction mechanism being difficult to clean during noise reduction, resulting in poor noise reduction performance. Utility Model Content
[0005] The purpose of this invention is to provide a noise reduction mechanism for an oil fume purification device to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A noise reduction mechanism for an oil fume purification device includes a purification device, an inlet pipe installed at one end of the purification device, an outlet pipe installed at the other end of the purification device, a sleeve installed on the surface of both the outlet pipe and the inlet pipe, a sound-absorbing component installed inside the sleeve, and a fixing component installed at one end of the sleeve.
[0008] The fastener includes an outer frame, which is fixedly connected to both sides of the sleeve. A rectangular groove is provided on one side of the outer frame, and a column is fixedly connected inside the outer frame. A spring is sleeved on the surface of the column.
[0009] A further improvement of this utility model is that: a sleeve block is fitted onto the surface of the column, a crossbar is fixedly connected to the right side of the sleeve block, a hollow frame is fixedly connected to the outer side of the sleeve block, and the other end of the hollow frame extends into the inner cavity of the sleeve. The hollow frame can limit the inner tube. When disassembling the sound-absorbing mesh, pulling the crossbar outward can cause the sleeve block to slide on the column.
[0010] A further improvement of the present invention is that the sound-silencing component includes an inner tube, which is inserted into the inside of the sleeve. The lower surface of the inner tube has square grooves reserved from left to right, which are used to place and fix the sound-silencing mesh.
[0011] A further improvement of the present invention is that: a first permanent magnet block is engaged at the bottom of the inner cavity of the square groove, a second permanent magnet block is attached to the top of the first permanent magnet block, and a noise-absorbing mesh is fixedly connected to one end of the second permanent magnet block. By pulling the noise-absorbing mesh upward, the second permanent magnet block can be separated from the first permanent magnet block.
[0012] A further improvement of the present invention is that the purification device includes a purification machine body, one end of which is fixedly connected to one side of the smoke inlet pipe, and sound-absorbing cotton is fixedly connected to the outside of the purification machine body. The noise generated by the vibration of the purification machine body is reduced by the sound-absorbing cotton and the sound insulation board.
[0013] A further improvement of this utility model is that: a sound insulation board is fixedly connected to the outer side of the sound-absorbing cotton, a spring shock absorber is installed on the outer side of the sound insulation board, and a noise reduction shell is threaded to one end of the spring shock absorber. The noise reduction shell is fitted onto the outside of the purifier body. When the purifier body vibrates during purification, the purifier body squeezes the sound-absorbing cotton and the sound insulation board, and the spring shock absorber dampens the vibration of the purifier body.
[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0015] 1. This utility model provides a noise reduction mechanism for an oil fume purification device. The hollow frame can limit the inner tube. When disassembling the silencing mesh, pulling the crossbar outward can cause the sleeve block to slide on the column. By squeezing the spring through the sleeve block, the sleeve block can drive the hollow frame to move. The hollow frame is moved to a position horizontal with the inner wall of the sleeve. Pulling the inner tube to the right can move it out of the sleeve. By pulling the silencing mesh upward, it can cause the second permanent magnet block to separate from the first permanent magnet block, thereby moving the silencing mesh out of the inner tube. The silencing mesh can be cleaned or replaced. It is easy to disassemble and improves the noise reduction effect.
[0016] 2. This utility model provides a noise reduction mechanism for an oil fume purification device. The noise reduction shell is fitted onto the outside of the purifier body. When the purifier body vibrates during purification, the purifier body squeezes the sound-absorbing cotton and sound insulation board. The spring shock absorber dampens the vibration of the purifier body. The noise generated by the vibration of the purifier body is reduced by the sound-absorbing cotton and sound insulation board, thereby reducing the noise of the purifier body and solving the problem of noise affecting the working environment of the purification device.

[0023] The present invention will be further described in detail below with reference to embodiments:
[0024] Example 1
[0025] like Figure 1-5As shown, this utility model provides a noise reduction mechanism for an oil fume purification device, including a purification device 1. One end of the purification device 1 is fitted with an inlet pipe 2, and the other end is fitted with an outlet pipe 6. Both the outlet pipe 6 and the inlet pipe 2 are fitted with sleeves 3. A sound-absorbing component 5 is installed inside the sleeves 3. One end of the sleeves 3 is fitted with a fixing component 4, which includes an outer frame 40 fixedly connected to both sides of the sleeves 3. A rectangular groove 45 is formed on one side of the outer frame 40. A column 46 is fixedly connected inside the outer frame 40, and a spring 42 is fitted onto the surface of the column 46. A sleeve block 43 is fitted onto the surface of the column 46. A crossbar 44 is fixedly connected to the right side of the sleeve block 43. A hollow frame 47 is fixedly connected to the outside of the sleeve block 43, and the other end of the hollow frame 47 extends into the inner cavity of the sleeve 3. The sound-absorbing component 5 includes an inner tube 50, which is inserted into the inside of the sleeve 3. A square groove 51 is reserved on the lower surface of the inner tube 50 from left to right. A first permanent magnet block 52 is snapped into the bottom of the inner cavity of the square groove 51. A second permanent magnet block 54 is attached to the top of the first permanent magnet block 52. A sound-absorbing mesh 53 is fixedly connected to one end of the second permanent magnet block 54.
[0026] Specifically, the hollow frame 47 can limit the inner tube 50. When disassembling the silencing mesh 53, pulling the crossbar 44 outward can cause the sleeve block 43 to slide on the column 46. By squeezing the spring 42 through the sleeve block 43, the sleeve block 43 can cause the hollow frame 47 to move along with it. The hollow frame 47 is moved to a position horizontal with the inner wall of the sleeve 3. Pulling the inner tube 50 to the right can move it out of the sleeve 3. By pulling the silencing mesh 53 upward, it can cause the second permanent magnet block 54 to separate from the first permanent magnet block 52, thereby moving the silencing mesh 53 out of the inner tube 50. The silencing mesh 53 can be cleaned or replaced. Disassembly is convenient and operation is simple.
[0027] Example 2
[0028] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the purification device 1 includes a purification machine body 14, one end of the purification machine body 14 is fixedly connected to one side of the smoke inlet pipe 2, a sound-absorbing cotton 12 is fixedly connected to the outside of the purification machine body 14, a sound insulation board 11 is fixedly connected to the outside of the sound-absorbing cotton 12, a spring shock absorber 13 is installed on the outside of the sound insulation board 11, and a noise reduction shell 10 is threadedly connected to one end of the spring shock absorber 13.
[0029] Specifically, the noise-reducing shell 10 is fitted onto the outside of the purifier body 14. When the purifier body 14 vibrates during purification, it compresses the sound-absorbing cotton 12 and the sound insulation board 11. The spring shock absorber 13 dampens the vibration of the purifier body 14. The noise generated by the vibration of the purifier body 14 is reduced by the sound-absorbing cotton 12 and the sound insulation board 11, thereby reducing the noise of the purifier body 14 and solving the problem of noise affecting the working environment of the purification device 1.
[0030] The working principle of the noise reduction mechanism of this fume purification device will be explained in detail below.
[0031] like Figure 1-4 As shown, the hollow frame 47 can limit the inner tube 50. When disassembling the silencing mesh 53, pulling the crossbar 44 outward can cause the sleeve block 43 to slide on the column 46. By squeezing the spring 42 through the sleeve block 43, the sleeve block 43 can cause the hollow frame 47 to move accordingly. When the hollow frame 47 is moved to a position horizontal with the inner wall of the sleeve 3, pulling the inner tube 50 to the right can move it out of the sleeve 3. By pulling the silencing mesh 53 upward, it can cause the second permanent magnet block 54 to separate from the first permanent magnet block 52, thereby moving the silencing mesh 53. The sound-absorbing mesh 53 can be cleaned or replaced inside the inner tube 50. It is easy to disassemble and simple to operate. The noise-reducing shell 10 is fitted onto the outside of the purifier body 14. When the purifier body 14 vibrates during purification, it squeezes the sound-absorbing cotton 12 and the sound insulation board 11. The spring shock absorber 13 dampens the vibration of the purifier body 14. The noise generated by the vibration of the purifier body 14 is reduced by the sound-absorbing cotton 12 and the sound insulation board 11, thus reducing the noise of the purifier body 14 and solving the problem of noise affecting the working environment of the purification device 1.
[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
