Description

Technical Field

[0001] This application relates to the field of nylon production technology, and in particular to a high-temperature resistant nylon production apparatus with a smoke removal structure. Background Technology

[0002] Polyamide, commonly known as nylon, is a general term for polymers whose main chain repeating units contain amide groups. Polyamide can be obtained by ring-opening polymerization of lactams or by condensation polymerization of diamines and diacids. Polyamide refers to polymers whose main chain segments contain polar amide groups. It was initially used as a raw material for manufacturing fibers. Later, due to its strength, wear resistance, self-lubrication, and wide operating temperature range, polyamide has become a widely used engineering plastic in industry. During the production of nylon, a large amount of smoke and dust is generated. Therefore, smoke removal structures are needed to assist in the nylon production process.

[0003] While existing high-temperature resistant nylon production equipment with smoke removal structures can effectively remove smoke, it often relies on a single removal box for adsorption and removal of the flue gas. This approach is not very effective for multi-path switching in terms of smoke adsorption and removal. Furthermore, when replacing the adsorption components inside the single removal box, the entire smoke removal structure needs to be shut down. If the flue gas continues to be discharged, it can cause the flue gas to diffuse, reducing the effectiveness of smoke removal. Utility Model Content

[0004] This application provides a high-temperature resistant nylon production device with a smoke removal structure to solve the problem that the common method of removing flue gas by adsorption using a single removal box is not very effective for multi-path switching, and that the entire smoke removal structure needs to stop operating when the adsorption components inside the single removal box are replaced.

[0005] This application provides a high-temperature resistant nylon production device with a smoke removal structure, including a main body of the production device. A smoke extraction pipe is provided on the top of the main body of the production device. A secondary diversion pipe is fixedly connected to one end of the smoke extraction pipe. A secondary smoke removal box is fixedly connected to one end of the secondary diversion pipe. A main diversion pipe located on one side of the secondary diversion pipe is fixedly connected to one end of the main diversion pipe. A main smoke removal box is fixedly connected to one end of the main smoke removal box. A flue gas adsorption component is provided inside the main smoke removal box. An air inlet pipe is fixedly connected to the outer wall of the main smoke removal box. An exhaust box is fixedly connected to one end of the air inlet pipe. An exhaust pipe is provided on the outer wall of the exhaust box. A fixed box is fixedly provided above the main smoke removal box. A worm gear is rotatably connected to the inner wall of the fixed box. A worm wheel rotatably connected to the outer wall of the worm gear is engaged with the outer wall of the fixed box. A sealing ring is provided on the inner wall of the main diversion pipe. A rotating plate that fits against the inner wall of the sealing ring is fixedly connected to the rotation center of the worm wheel through a connecting shaft.

[0006] Preferably, a servo motor is fixedly connected to the outer wall of the fixed box, and a bevel gear set fixedly connected to the output end of the servo motor is fixedly connected to the outer wall of the worm gear.

[0007] Preferably, the worm gears are provided in two sets, and the two sets of worm gears rotate in opposite directions.

[0008] Preferably, there are two sets of rotating plates, and the two sets of rotating plates are arranged in a one-to-one correspondence with the worm gear.

[0009] Preferably, the outer wall contour of the connection between the main branch pipe and the secondary branch pipe is U-shaped.

[0010] Preferably, the secondary smoke removal box and the main smoke removal box are respectively connected to the air inlet pipe.

[0011] Preferably, the outer wall profile of the air inlet duct is U-shaped.

[0012] Beneficial effects:

[0013] Considering that the existing high-temperature nylon production equipment with smoke removal structure can effectively remove smoke, it often uses a single removal box to adsorb and remove the smoke. The effect of smoke adsorption and removal is not high when switching between multiple paths. When replacing the adsorption components inside the single removal box, the entire smoke removal structure needs to stop operating. However, if the smoke is still being discharged, it will cause the smoke to spread and reduce the smoke removal effect.

[0014] When switching the flue gas removal path is required to improve the removal effect of flue gas without stopping the machine, the servo motor drives the worm gear to rotate through the bevel gear set. The rotation of the worm gear, through the connection of the worm wheel, drives the rotating plate to alternately flip inside the main diversion pipe and the secondary diversion pipe. This causes the conveying cavities of the main diversion pipe and the secondary diversion pipe to be closed and adjusted alternately, thereby improving the flue gas removal efficiency of the smoke removal structure without stopping the machine.

[0029] This utility model provides, for example Figure 1-4The high-temperature resistant nylon production device with a smoke removal structure shown includes a main body 1. A smoke extraction pipe 2 is installed at the top of the main body 1. One end of the smoke extraction pipe 2 is fixedly connected to a secondary diversion pipe 3. One end of the secondary diversion pipe 3 is fixedly connected to a secondary smoke removal box 4. One end of the smoke extraction pipe 2 is fixedly connected to a main diversion pipe 5 located on one side of the secondary diversion pipe 3. One end of the main diversion pipe 5 is fixedly connected to a main smoke removal box 6. A flue gas adsorption assembly 7 is installed inside the main smoke removal box 6. The outer wall of the main smoke removal box 6... An air inlet pipe 8 is fixedly connected, and a smoke exhaust box 9 is fixedly connected to one end of the air inlet pipe 8. A smoke exhaust pipe 10 is provided on the outer wall of the smoke exhaust box 9. A fixed box 11 is fixedly installed above the main smoke removal box 6. A worm gear 14 is rotatably connected to the inner wall of the fixed box 11. A worm wheel 15 is meshed with the outer wall of the worm gear 14 and rotatably connected to the inner wall of the fixed box 11. A sealing ring 17 is provided on the inner wall of the main diversion pipe 5. A rotating plate 16 that fits against the inner wall of the sealing ring 17 is fixedly connected to the rotation center of the worm wheel 15 through a connecting shaft.

[0030] The outer wall of the fixed box 11 is fixedly connected to a servo motor 12, and the output end of the servo motor 12 is fixedly connected to a bevel gear set 13 that is fixedly connected to the outer wall of the worm gear 14.

[0031] The bevel gear set 13 is designed to drive the two sets of worm gears 15 to rotate relative to each other.

[0032] The worm gear 15 is provided in two sets, and the two sets of worm gear 15 rotate in opposite directions.

[0033] It is advantageous to set two sets of worm gears 15 with opposite rotation directions to achieve the effect of driving the rotating plate 16 to rotate relative to each other.

[0034] The rotating plate 16 is provided in two sets, and the two sets of rotating plates 16 are arranged in a one-to-one correspondence with the worm gear 15.

[0035] The one-to-one correspondence between the rotating plate 16 and the worm gear 15 facilitates convenient switching of the flue gas conveying path.

[0042] Working principle: When using this high-temperature resistant nylon production device with a smoke removal structure, it is necessary to switch the smoke removal path to improve the smoke removal effect without stopping the machine. When the servo motor 12 is turned on, the worm gear 14 is driven to rotate through the bevel gear set 13. The rotation of the worm gear 14 is connected through the worm wheel 15, which drives the rotating plate 16 to alternately rotate on the inner wall of the main diversion pipe 5 and the secondary diversion pipe 3. This causes the conveying inner cavity of the main diversion pipe 5 and the secondary diversion pipe 3 to be closed and adjusted alternately, thereby improving the smoke removal efficiency of the smoke removal structure without stopping the machine.
