Technical Field
[0001] This utility model relates to the field of fan connection equipment technology, specifically a novel flexible connection device for fans used in the negative electrode industry. Background Technology
[0002] In the production process of negative electrode materials, fans are important auxiliary equipment, mainly used for workshop ventilation, material conveying and other processes. Fans and pipelines usually need to be connected by flexible connection devices to compensate for the vibration and displacement generated during the operation of the fans, while also playing a role in sealing and noise reduction.
[0003] Existing flexible connection devices for wind turbines are inconvenient to install and disassemble. Traditional flexible connection devices are fixed to the flange with multiple bolts, requiring the removal of each bolt individually during installation and disassembly. This operation is cumbersome, time-consuming, and labor-intensive. Moreover, most of them are made of a single canvas or rubber material, which has poor wear resistance and is easily worn by dust after long-term use, leading to seal failure and dust leakage. This not only pollutes the environment but also affects the production quality of the negative electrode material. Insufficient high temperature and corrosion resistance makes them prone to aging and damage in high temperature and corrosive environments, resulting in a short service life and frequent replacement, which increases the maintenance costs for enterprises. Therefore, it is necessary to design a new type of flexible connection device for wind turbines in the negative electrode industry to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a novel flexible connection device for use in negative electrode industry fans, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel flexible connection device for fans in the negative electrode industry, comprising a flexible connection body and a fan end pipe, wherein the upper and lower ends of the flexible connection body are fixedly connected to end flanges, the outer end of the end flange is sealed to the fan end pipe, a fixed frame is fixedly connected to the outer side of the end flange, a driven slide rod is slidably connected inside the fixed frame, and a locking pin is fixedly connected to the inner end of the driven slide rod, the locking pin being slidably connected to the fixed frame, the end flange and the fan end pipe respectively;

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This novel flexible connection device for negative electrode industry fans allows the end flange to be inserted into the inside of the fan end pipe. Simultaneously, the extrusion arc plate and the end flange are compressed, causing the transmission rod to drive the transmission plate to move outward.

[0015] 2. This novel flexible connection device, applied to fans in the negative electrode industry, effectively prevents dust and gas leakage from the connection between the connecting flange and the flexible connection body through the rubber ring made of fluororubber, further improving the sealing performance of the device. The polytetrafluoroethylene layer effectively resists the wear of negative electrode dust and the erosion of corrosive gases, while the fiberglass cloth layer enhances the structural stability of the flexible connection body and facilitates the deformation of the flexible connection body with the vibration of the fan. The stainless steel wire mesh layer further improves the impact resistance and service life of the flexible connection body, preventing the flexible connection body from cracking during long-term use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1
[0024] Please refer to Figure 1-5 As shown, this utility model provides a novel flexible connection device for fans in the negative electrode industry, including a flexible connection body 1 and a fan end pipe 3. The upper and lower ends of the flexible connection body 1 are fixedly connected to end flanges 2. The outer end of the end flanges 2 is sealed to the fan end pipe 3. A fixing frame 4 is fixedly connected to the outer side of the end flanges 2. A driven slide rod 5 is slidably connected inside the fixing frame 4. A locking pin 6 is fixedly connected to the inner end of the driven slide rod 5. The locking pin 6 is slidably connected to the fixing frame 4, the end flanges 2 and the fan end pipe 3 respectively. The locking pin 6 can fix the end flanges 2 and the fan end pipe 3 to each other through the action of the locking pin 6, and the driven slide rod 5 can drive the locking pin 6.
[0025] The flexible connector body 1 is configured as a multi-layer composite structure, comprising a polytetrafluoroethylene (PTFE) layer 101, a fiberglass cloth layer 102, and a stainless steel wire mesh layer 103. A high-temperature resistant adhesive is provided between the PTFE layer 101, the fiberglass cloth layer 102, and the stainless steel wire mesh layer 103. The PTFE layer 101 effectively resists the wear of negative electrode dust and the erosion of corrosive gases. The fiberglass cloth layer 102 has good tensile strength and flexibility, which enhances the structural stability of the flexible connector body 1 and facilitates the deformation of the flexible connector body 1 with the vibration of the fan. Furthermore, the stainless steel wire mesh layer 103 further improves the impact resistance and service life of the flexible connector body 1, preventing the flexible connector body 1 from cracking during long-term use.
[0026] Specifically, the inner end face of the fan end pipe 3 is provided with a mating slot 7, and the inside of the mating slot 7 is provided with a sealing gasket 8. The sealing gasket 8 is sealed to the end flange 2. The sealing gasket 8 can seal the connection between the end flange 2 and the fan end pipe 3. The outer walls of the end flange 2 and the fan end pipe 3 are both provided with locking holes 9. The position and size of the locking holes 9 correspond to the position and size of the locking pin 6. The locking holes 9 facilitate the insertion of the locking pin 6.
[0027] Specifically, a transmission plate 10 is provided on the outer end face of the fixed frame 4. The transmission plate 10 is fixedly connected to the driven slide rod 5. A telescopic rod 11 is fixedly connected to the upper end of the fixed frame 4. A compression ring plate 12 is fixedly connected to the upper end of the inner movable rod of the telescopic rod 11. A transmission rod 13 is rotatably connected to the outer side of the compression ring plate 12. The transmission rod 13 is rotatably connected to the transmission plate 10. A spring 14 is provided inside the lower tube of the telescopic rod 11. By compressing the compression ring plate 12 and the end flange 2, the telescopic rod 11 can be compressed, and the transmission rod 13 drives the transmission plate 10 to move outward. The movement of the sliding rod 5 causes the locking pin 6 to move outward, thus removing the obstruction between the end flange 2 and the fan end pipe 3. When the compression ring plate 12 is released, the spring 14 extends, causing the telescopic rod 11 to extend, which in turn causes the compression ring plate 12 to move outward. This causes the transmission rod 13 to drive the transmission plate 10 to move inward, allowing the sliding rod 5 to drive the locking pin 6 to move inward. This allows the locking pin 6 to be inserted into the locking holes 9 inside the end flange 2 and the fan end pipe 3, respectively, achieving rapid fixing of the end flange 2 and the fan end pipe 3.
[0028] Specifically, a sealing groove 15 is provided on the inner end face of the end flange 2, and a sealing ring 16 is fixedly connected inside the sealing groove 15. The sealing ring 16 is fixedly connected to the flexible connection body 1. The sealing ring 16 is made of fluororubber. The fluororubber sealing ring 16 can effectively prevent dust and gas from leaking from the connection between the end flange 2 and the flexible connection body 1, further improving the sealing performance of the device.
[0029] Specifically, the mating ends of the end flange 2 and the fan end pipe 3 are both double-layered, which can further improve the connection sealing between the flexible connection device and the fan or pipe.
[0030] Specifically, the surface of the end flange 2 is provided with a galvanized layer, which can effectively prevent the end flange 2 from rusting and corroding, and extend the service life of the end flange 2.
[0031] Working Principle: This utility model is a novel flexible connection device for negative electrode industry fans. When assembling the flexible connection for this negative electrode industry fan, the extrusion annular plate 12 and the end flange 2 are first extruded, thereby compressing the telescopic rod 11 and causing the transmission rod 13 to drive the transmission plate 10 to move outwards. This causes the driven slide rod 5 to drive the locking pin 6 to move outwards, thus removing the obstruction between the end flange 2 and the fan end pipe 3. At this point, the end flange 2 and the fan end pipe 3 can be tightly connected, and the connection is sealed by the sealing gasket 8. Then, the extrusion annular plate 12 is released, causing the spring 14 to extend, which in turn causes the telescopic rod 11 to extend. This allows the extrusion annular plate 12 to move outwards, and the transmission rod 13 to drive the transmission plate 10 to move inwards. This causes the driven slide rod 5 to drive the locking pin 6 inwards, allowing the locking pin 6 to be inserted into the end flange 2 and the fan end pipe 3 respectively. The internal locking socket 9 enables quick fixing of the end flange 2 and the fan end pipe 3. During disassembly, simply press down on the annular plate 12 again to remove the flexible connection device from the fan or pipeline. The operation is simple and quick, greatly saving installation and disassembly time. When the flexible connection device is in use, the fluororubber sealing ring 16 can effectively prevent dust and gas from leaking from the connection between the end flange 2 and the flexible connection body 1, further improving the sealing performance of the device. The polytetrafluoroethylene layer 101 can effectively resist the wear of negative electrode dust and the erosion of corrosive gases. The fiberglass cloth layer 102 has good tensile strength and flexibility, which can enhance the structural stability of the flexible connection body 1 and facilitate the deformation of the flexible connection body 1 with the vibration of the fan. The stainless steel wire mesh layer 103 further improves the impact resistance and service life of the flexible connection body 1, preventing the flexible connection body 1 from cracking during long-term use.
