Description

Technical Field

[0001] This invention relates to the field of high-speed machine waste discharge technology, specifically a waste discharge damper for a high-speed enameled wire machine. Background Technology

[0002] High-speed machines (such as ovens in industrial production) generate a large amount of waste gas during operation, which needs to be discharged in a timely manner through a waste discharge system to ensure the normal operation of the equipment and the safety of the production environment. As the core component of the waste discharge system, the opening degree adjustment of the waste gas discharge damper directly affects the waste gas discharge efficiency, furnace temperature stability, and equipment energy consumption.

[0003] The existing exhaust dampers of high-speed enameled wire machines mostly adopt a structure of manually adjusting screws to drive the baffles. The adjustment accuracy depends on the operator's experience, and uneven force can easily cause sudden changes in opening. In addition, there is a lack of precise guidance and scale reference, resulting in large errors. The damper baffles are mostly fixed with bolts, which is cumbersome to disassemble and assemble. Later cleaning and maintenance require long-term downtime, resulting in high maintenance costs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a waste exhaust damper for high-speed enameled wire machines. This solves the problems of existing waste exhaust dampers for high-speed enameled wire machines, which mostly use manually adjusted screws to drive the baffles. The adjustment accuracy depends on the operator's experience, and uneven force can easily lead to sudden changes in opening. Furthermore, they lack precise guidance and scale references, resulting in large errors. Additionally, the damper baffles are mostly fixed with bolts, which is cumbersome to disassemble and assemble, and requires long downtime for cleaning and maintenance, resulting in high maintenance costs.

[0005] The present invention provides the following technical solution: a waste discharge damper for a high-speed enameled wire machine, comprising a waste discharge pipe, a sealed box fixedly installed at the top of the waste discharge pipe, the sealed box having an internal slot and an opening at one end, the sealed box being connected to the waste discharge pipe, and an air outlet pipe being connected to the upper end of the sealed box.

[0006] A support frame is fixedly installed between the waste discharge pipe and the air outlet pipe. A screw is rotatably installed between the support frame and the air outlet pipe. A threaded sleeve is threaded onto the surface of the screw. An installation box is fixedly installed on the lower surface of the threaded sleeve. A connecting plate is fixedly installed on the surface of the installation box. A damper baffle is detachably installed on the connecting plate and the installation box.

[0007] Preferred technical solution 1: A sliding rod is fixedly connected between the support frame and the waste discharge pipe, a sliding sleeve is slidably fitted on the surface of the sliding rod, the sliding sleeve is fixedly connected to the mounting box, and scale lines are provided on the support frame.

[0008] This design uses a sliding rod and a sliding sleeve to guide the mounting box and prevent deflection.

[0009] Preferred technical solution 2: A motor bracket is fixedly installed on the surface of the support frame, and a drive motor is fixedly installed on the motor bracket. The output end of the drive motor passes through the support frame and is fixedly connected to the screw.

[0010] This solution replaces manual labor with motor drive, reducing labor intensity and enabling the damper to move at a constant speed, avoiding sudden changes in opening.

[0011] Preferred technical solution 3: One end of the damper is fixedly connected to an installation plate, and the surface of the connection plate is provided with an installation groove that matches the installation plate.

[0012] This solution allows the mounting plate to fit into the mounting slot for pre-positioning, quickly aligning the assembly position and simplifying the installation process.

[0013] Preferred technical solution four: A bidirectional lead screw is rotatably installed inside the mounting box. Two lead screw sleeves are threaded onto the surface of the bidirectional lead screw. Clamping plates are fixedly connected to the surfaces of the two lead screw sleeves. Multiple locking blocks are fixedly connected to the surfaces of the two clamping plates. Multiple locking grooves matching the locking blocks are opened on the upper and lower surfaces of the mounting plate. The top end of the bidirectional lead screw extends to the outside of the mounting box and is fixedly connected to an operating handle.

[0014] This solution uses a bidirectional screw to drive the clamping plate to open and close. The locking block and the slot are firmly engaged and fixed, allowing the damper to be installed and removed without removing bolts. This makes the operation efficient and facilitates later cleaning and maintenance.

[0015] Preferred technical solution five: A limiting rod is fixedly installed inside the mounting box, and two limiting sleeves are slidably sleeved on the surface of the limiting rod, with the two limiting sleeves respectively fixedly connected to the two clamping plates.

[0016] This solution uses a limit rod and a limit sleeve to restrict the movement direction of the clamping plate, prevent torsion, and ensure precise alignment of the locking blocks.

[0017] Preferred technical solution six: The surfaces of the screw and the slide are both fitted with protective tubes, the protective tubes being corrugated flexible tubes, and the protective tubes do not affect the movement of the screw sleeve and the slide sleeve.

[0018] This solution uses a corrugated protective pipe to block dust and oil, prevent thread jamming, and ensure smooth adjustment.

[0019] Preferred technical solution seven: The damper baffle is fitted with a sealing sleeve, which is made of high temperature resistant elastic material, and the sealing sleeve is interference-fitted with the slot.

[0020] This design features a high-temperature resistant elastic sealing sleeve that is interference-fitted with the empty groove, ensuring a tight seal and preventing exhaust gas leakage.

[0021] Compared with the prior art, the present invention provides a waste exhaust damper for a high-speed enameled wire machine, which has the following beneficial effects:

[0022] (1) The exhaust damper of the high-speed enameled wire machine is driven by a screw drive motor, which, together with the guiding action of the slide rod and the slide sleeve, enables the damper to move smoothly. Combined with the scale line of the support frame, the opening can be accurately controlled without additional tools, avoiding the errors and uneven force of manual adjustment. At the same time, the motor can be adapted to an external controller to achieve automatic adjustment. It can adapt to parameters such as furnace temperature and exhaust gas volume of the high-speed machine in real time, ensuring that the throttling effect is stable, effectively reducing furnace temperature loss, reducing equipment energy consumption, and adapting to different working conditions.

[0023] (2) The exhaust damper of the high-speed enameled wire machine is fixed to the bidirectional screw clamping mechanism by the mounting plate, and the connection is firm. It can be disassembled without removing bolts, which is convenient for quick cleaning and replacement. The sealing sleeve is interference fit to prevent exhaust gas leakage, the protective tube blocks impurities, and the guide limit structure avoids component torsion deformation.

[0033] A support frame 5 is fixedly installed between the waste discharge pipe 1 and the air outlet pipe 4. A screw 6 is rotatably installed between the support frame 5 and the air outlet pipe 4. A screw sleeve 7 is threaded onto the surface of the screw 6. An installation box 8 is fixedly installed on the lower surface of the screw sleeve 7. A connecting plate 9 is fixedly installed on the surface of the installation box 8. A damper baffle 10 is detachably installed on the connecting plate 9 and the installation box 8.

[0034] Example 2: The difference between this example and Example 1 is that a sliding rod 11 is fixedly connected between the support frame 5 and the waste discharge pipe 1, a sliding sleeve 12 is slidably fitted on the surface of the sliding rod 11, the sliding sleeve 12 is fixedly connected to the mounting box 8, and scale lines are provided on the support frame 5.

[0035] Example 3: The difference between this example and Example 1 is that a motor bracket 13 is fixedly installed on the surface of the support frame 5, a drive motor 14 is fixedly installed on the motor bracket 13, and the output end of the drive motor 14 passes through the support frame 5 and is fixedly connected to the screw 6.

[0036] Example 4: The difference between this example and Example 1 is that, in this example, one end of the damper 10 is fixedly connected to the mounting plate 15, and the surface of the connecting plate 9 is provided with a mounting groove 16 that matches the mounting plate 15.

[0037] Example 5: The difference between this example and Example 1 is that a bidirectional lead screw 17 is rotatably installed inside the mounting box 8. Two lead screw sleeves 18 are threaded onto the surface of the bidirectional lead screw 17. Clamping plates 19 are fixedly connected to the surface of each of the two lead screw sleeves 18. Multiple locking blocks 20 are fixedly connected to the surface of each of the two clamping plates 19. Multiple slots 21 matching the locking blocks 20 are opened on the upper and lower surfaces of the mounting plate 15. The top end of the bidirectional lead screw 17 extends to the outside of the mounting box 8 and is fixedly connected to an operating handle 22.

[0038] Example 6: The difference between this example and Example 1 is that a limiting rod 23 is fixedly installed inside the mounting box 8, and two limiting sleeves 24 are slidably sleeved on the surface of the limiting rod 23. The two limiting sleeves 24 are fixedly connected to the two clamping plates 19 respectively.

[0039] Example 7: The difference between this example and Example 1 is that the surfaces of the screw 6 and the slide rod 11 are both covered with protective tubes 25. The protective tubes 25 are corrugated hoses and do not affect the movement of the screw sleeve 7 and the slide sleeve 12.

[0040] Example 8: The difference between this example and Example 1 is that the damper baffle 10 is fitted with a sealing sleeve 26, which is made of high temperature resistant elastic material and is interference-fitted with the groove 3.

[0041] In summary, the control method and detailed connection means of the exhaust damper of the high-speed enameled wire machine are known technologies in the field. Those skilled in the art can connect all electrical components and their compatible power supplies through wires, and should select a suitable controller according to the actual situation to meet the control requirements. The detailed connection means and control scheme are known technologies in the field. The following mainly introduces the working principle and process, and will not explain the electrical control. At the same time, the screw 6 and the screw sleeve 7 meet the self-locking condition, and the bidirectional lead screw 17 and the two lead screw sleeves 18 meet the self-locking condition.

[0042] When the exhaust damper of the high-speed enameled wire machine is working, the drive motor 14 first drives the screw 6 to rotate, and the screw sleeve 7 drives the mounting box 8 to move synchronously. The operator can accurately control the moving distance of the mounting box 8 according to the scale line on the support frame 5, and then adjust the depth of the damper baffle 10 into the inner groove 3 of the closed box 2. The high temperature resistant elastic sealing sleeve 26 sleeved on the outside of the damper baffle 10 is interference fit with the groove 3 to ensure the sealing performance between the exhaust pipe 1 and the exhaust pipe 4. The opening of the exhaust gas discharge can be accurately controlled by changing the shielding area of ​​the damper baffle 10.

[0043] When it is necessary to install or replace the damper 10, turn the operating handle 22 to drive the double-acting screw 17 to rotate, thereby driving the two screw sleeves 18 and the clamping plate 19 to move synchronously away from each other. After inserting the mounting plate 15 at one end of the damper 10 into the mounting groove 16 of the connecting plate 9, turn the operating handle 22 in the opposite direction to make the locking block 20 on the clamping plate 19 lock into the locking groove 21 of the mounting plate 15, thus completing the quick fixing of the damper 10. This enables the quick installation and removal of the damper 10, making it convenient to clean or replace the damper 10.
