Description

Technical Field

[0001] This utility model relates to the field of diaphragm drying, specifically to a heat insulation device for an oven and an oven. Background Technology

[0002] In existing wet-process base film production lines, the large inlet and outlet openings of the drying ovens cause continuous heat loss, affecting the drying efficiency of the diaphragm. Furthermore, this significant heat loss raises the ambient temperature of adjacent equipment, impacting their functionality and ultimately reducing the quality of the produced diaphragm. To mitigate this heat loss, current technology reduces the size of the oven opening. However, given the relatively wide diaphragm itself, reducing the opening has limited effectiveness in preventing heat loss. Additionally, an excessively small opening can cause friction against the diaphragm, negatively impacting its quality. Utility Model Content

[0018] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them.

The various technical features in this utility model can be combined interactively without contradicting each other.

[0019] Please see Figure 1 , 3 A preferred embodiment of this utility model provides a heat insulation device for an oven, including a mounting frame 1, a heat insulation component 2, a negative pressure suction component 3, and a wind baffle component 4. The mounting frame 1 is provided with a diaphragm channel 11. The heat insulation component 2 and the negative pressure suction component 3 are respectively located on the inner and outer sides of the diaphragm channel 11. The heat insulation component 2 is used to form a low-pressure area at the diaphragm channel 11 to prevent heat leakage. The negative pressure suction component 3 is used to absorb a small amount of outflowing hot air to prevent equipment in adjacent processes from being affected. The wind baffle component 4 is arranged on the side of the diaphragm channel 11 to reduce the opening size of the diaphragm channel 11 and further prevent heat leakage.

[0020] Specifically, the heat insulation component 2 includes a main exhaust duct 21, two secondary exhaust ducts 22, and two exhaust fans 23, both installed inside the mounting bracket 1. The two exhaust fans 23 are positioned opposite each other on the upper and lower sides of the diaphragm channel 11 to form a low-pressure area at the diaphragm channel 11. In use, the mounting bracket 1 is installed at the inlet or outlet of the oven, connecting the diaphragm channel 11 to the inlet or outlet of the oven. Under the action of the two exhaust fans 23, a low-pressure area is formed above and below the diaphragm channel 11, while the inner and outer sides of the oven are high-pressure areas. The exhaust fans 23 can directly draw away the hot air flowing out of the oven's inlet and outlet, thus preventing heat leakage from the oven's inlet and outlet and preventing any impact on the equipment in the processes before and after the oven.

[0021] In this embodiment, the air outlets of the two exhaust components 23 are respectively connected to the two secondary exhaust pipes 22. Both secondary exhaust pipes 22 are connected to the main exhaust pipe 21. The main exhaust pipe 21 is connected to the external exhaust device. The air drawn by the two exhaust components 23 is transported through the two secondary exhaust pipes 22 and then centrally transported to the external exhaust device by the main exhaust pipe 21 for centralized treatment or secondary utilization.

[0022] Please see Figure 3 A damper 24 is installed between the secondary exhaust duct 22 and the main exhaust duct 21. The output end of the damper 24 is unidirectionally electrically connected to the input end of the exhaust component 23. The damper 24 can control the opening or closing of the exhaust component 23 for easy use. The damper 24 is connected to the secondary exhaust duct 22 through a flexible hose 25. The flexible hose 25 can absorb the vibration between the damper 24 and the secondary exhaust duct 22, reduce the noise during operation of the device, and avoid resonance or structural fatigue caused by rigid connection.

[0023] Please see Figure 1 The negative pressure suction assembly 3 includes a suction component 31 and a suction nozzle 32 installed on the outside of the mounting frame 1. The input end of the suction nozzle 32 faces the diaphragm channel 11. The suction component 31 is used to provide suction to the suction nozzle 32 so that the suction nozzle 32 can further absorb the small amount of hot air flowing out of the oven and prevent it from affecting the equipment in the processes before and after the oven.

[0024] In this embodiment, the suction component 31 includes a fan 311. The air inlet of the fan 311 is connected to the nozzle 32 through the suction pipe 33, and the air outlet of the fan 311 is connected to an external exhaust device. The suction pipe 33 transmits the suction force of the fan 311 to the nozzle 32, so that the nozzle 32 can absorb the leaked hot air, and the fan 311 can transport the hot air absorbed by the nozzle 32 to the external exhaust device for centralized treatment or secondary utilization.

[0025] Please see Figure 1 , 4 There are two wind deflector components 4, and the two wind deflector components 4 are arranged opposite each other on the upper and lower sides of the diaphragm channel 11. The wind deflector component 4 includes a wind deflector plate 41 and a support frame 42 mounted on the mounting bracket 1. The wind deflector plate 41 is mounted on the support frame 42, and the two wind deflector plates 41 respectively block the upper and lower sides of the diaphragm channel 11 to reduce the height of the diaphragm channel 11 and further prevent heat leakage.

[0026] Please see Figure 4 , 5The windbreak assembly 4 also includes two movable baffles 43, which are respectively disposed on the left and right sides of the windbreak plate 41. The support frame 42 includes a horizontally arranged first guide rail 421. Both movable baffles 43 are slidably connected to the first guide rail 421 via pulleys 422, and the windbreak plate 41 is fixedly installed on the first guide rail 421. By sliding the movable baffles 43 left and right along the first guide rail 421, the blocking range of the movable baffles 43 can be changed to accommodate diaphragms of different widths, thus expanding the applicability of the device.

[0027] Please see Figure 4 , 6 The support frame 42 also includes a helical crank 423 and a vertically arranged second guide rail 424. The second guide rail 424 is mounted on the mounting bracket 1, and the first guide rail 421 is slidably mounted on the second guide rail 424 via a slider 425. The helical crank 423 includes a mounting plate 426, a knob 427, and a vertically arranged lifting rod 428. The mounting plate 426 is fixedly mounted on the second guide rail 424, and the lifting rod 428 is rotatably mounted on the mounting plate 426. One end of the lifting rod 428 is fixedly connected to the knob 427, and the other end is threadedly connected to the first guide rail 421. Due to the threaded engagement between the lifting rod 428 and the first guide rail 421, rotating the knob 427 allows the first guide rail 421 to rise and fall along the second guide rail 424 via the slider 425, thereby changing the height of the baffle 41 and the movable baffle 43 on the first guide rail 421, further changing the area where the diaphragm channel is blocked, and further expanding the applicability of the device.

[0028] Please see Figure 4 , 7 To improve the stability of the connection between the wind deflector 41 and the movable baffle 43, a bent sheet metal 411 is fixedly provided on the side of the wind deflector 41 away from the first guide rail 421. The bent sheet metal 411 has an arc groove 412. The movable baffle 43 is slidably disposed in the arc groove 412 on the side away from the first guide rail 421. During the process of sliding the movable baffle 43 along the first guide rail 421, the movable baffle 43 slides synchronously in the arc groove 412. The bent sheet metal 411 can limit the shaking of the movable baffle 43.

[0029] Please see Figure 1 , 2 The diaphragm channel 11 has horizontal guide grooves 111 on both the upper and lower sides. Two bellows covers 112 are slidably connected in the guide grooves 111. The two bellows covers 112 are installed on the left and right sides of the diaphragm channel 11 respectively. The width of the diaphragm channel 11 can be changed by the extension and retraction of the two bellows covers 112 to prevent hot air from flowing out from both sides of the diaphragm channel 11.

[0030] A preferred embodiment of this utility model also provides an oven, including an oven body and two oven insulation devices as described in the above embodiments. The oven body is provided with a diaphragm inlet and a diaphragm outlet. The inner sides of the two mounting brackets 1 face the diaphragm inlet and the diaphragm outlet respectively, and the two diaphragm channels 11 are respectively connected to the diaphragm inlet and the diaphragm outlet. Under the action of the two exhaust components 23, a low-pressure area is formed above and below the diaphragm channels 11, while the inner and outer sides of the oven are high-pressure areas. The exhaust components 23 can directly suck away the hot air flowing out of the oven's inlet and outlet, thus preventing heat leakage from the diaphragm inlet and outlet of the oven. At the same time, the exhaust component 31 can provide suction to the suction nozzle 32, and the suction nozzle 32 can further absorb the small amount of hot air flowing out of the oven, preventing it from affecting the equipment in the processes before and after the oven.

[0031] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
