Description

Technical Field

[0001] The present invention relates to the technical field of autoclaves, and specifically to an autoclave with a distributed heat source. Background Art

[0002] As the main production equipment for aerospace composite parts, the autoclave is a large plastic pressure vessel with an integral heating system and the structure of a nose plastic autoclave. Since the autoclave is a pressure vessel, its common structure is a cylinder with one end closed and the other end open, providing the necessary heat and pressure for the compaction and curing of advanced composite parts. Usually, the size of aerospace composite parts is very large, so the autoclave must be larger. At the same time, some composite forming requires higher pressure and temperature. In response to this situation, special autoclaves need to be built, but the cost will be quite high. Fortunately, most applications only require medium temperature and pressure.

[0003] The existing autoclave has a relatively simple structure and a single heat source, resulting in a slow autoclaving efficiency when the device is in use, affecting the later use of the device. And the main pressurizing medium of the autoclave is nitrogen. For convenience, air injection is usually selected. However, air has the risk of spontaneous combustion when heated. The method of using air pressurization can only be applied to autoclaves in a limited state (only for low-temperature curing systems). In addition, the autoclave lacks a blank fixing mechanism inside, and the stability of the blank placed in the autoclave cannot be guaranteed.

[0004] Therefore, those skilled in the art provide an autoclave with a distributed heat source to solve the problems raised in the above background art. Summary of the Invention

[0038] As shown in the drawings of the specification Figures 1 - 11 shown, the present invention provides an autoclave with distributed heat sources, including a tank body 1. One side of the inner cavity of the tank body 1 is provided with an inner tank 2. A heat source device 3 is fixedly arranged on one outer wall of the inner tank 2. A spiral heat exchange tube 4 is arranged on the outer wall of the inner tank 2. First air inlet pipes 5 communicating with the heat exchange tube 4 are arranged at both the top and the bottom of the heat source device 3. A regulating valve 6 is arranged on each air inlet pipe. The regulating valve 6 is a prior art similar to a flow valve and can control the exhaust volume and exhaust speed of the first air inlet pipe 5 discharging into the heat exchange tube 4. The heat source device 3 is an existing device burning natural gas fuel, such as Figure 2 , Figure 5As shown, the high-temperature gas generated by combustion in the present invention circulates through the heat exchange tube 4 to provide a uniform, stable, and effective heat source for the inner tank 2 of the autoclave cavity. The spiral heat exchange tube 4 is connected to the heat source device 3, and the two cooperate to dissipate heat evenly and distributively to the blank in the autoclave. By the way of distributed heat source dissipation, the hot pressing efficiency of the tank body 1 itself can be improved;

[0039] As Figure 3 shown, in this embodiment, sliding grooves 7 are provided on the inner cavity side walls of the inner tank 2. The sliding grooves 7 are slidably connected with sliding blocks 8. The sliding blocks 8 are fixedly connected with sliding plates 9. Multiple groups of clamping seats 10 are equidistantly arranged on the sliding plates 9. The inner side walls of each group of clamping seats 10 are fixedly connected with first springs 11. The first springs 11 are elastically connected with clamping plates 12. Specifically in implementation, first, the blanks to be hot pressed are sequentially placed on the sliding plate 9. The clamping plates 12 can be elastically pushed by the first springs 11 on the clamping seats 10 to fix the blanks in the sliding plate 9. Then, the sliding plate 9 together with the blanks is slid into the inner cavity of the inner tank 2 through the sliding of the sliding blocks 8 in the sliding grooves 7. The blanks can be fixed inside the tank body 1 for hot pressing work, and it is also convenient to slide the blanks into and out of the tank body 1, improving the working efficiency of the device;

[0040] Specifically, as Figure 4 shown, an air inlet 13 is provided on one side above the tank body 1. Below the air inlet 13, there is a purification box 14 in contact with the top of the tank body 1. One side of the purification box 14 is fixedly provided with a second intake pipe 15 communicating with the inner cavity of the inner tank 2. In the middle of the inner cavity of the purification box 14, a placement plate 16 is fixedly provided. On one side below the placement plate 16, there is a condenser 17, and on the other side below it, there is an evaporator 18. Both the condenser 17 and the evaporator 18 are connected with spiral exhaust pipes 19 that can pass through the placement plate 16 and extend to the inner cavity at the top of the purification box 14. Specifically in implementation, when the outside air is discharged into the purification chamber from the air inlet 13, then the condenser 17 is turned on and cold air is generated and introduced into the exhaust pipe 19 connected to it to cool and liquefy the air. Then the evaporator 18 is turned on to generate high-temperature gas and introduce it into the corresponding exhaust pipe 19 to heat up the liquefied air until the boiling point of nitrogen. When it reaches the boiling point, at this time, the air only remains in the gaseous form of nitrogen. Then the nitrogen is discharged into the inner tank 2 through the second intake pipe 15 to achieve pressurization during the hot pressing of the blanks in the tank body 1. It can be seen from this that the present invention can purify the air entering the tank body 1, extract nitrogen in the air as a pressurizing medium to enter the tank body 1, eliminate the hidden danger of the air directly entering the tank body 1 and catching fire when heated, and improve the use safety of the device;

[0041] It is worth mentioning that, as Figure 4As shown, flow valves (not shown) of the prior art are provided on both the air inlet 13 and the second intake pipe 15 in the present invention. They are of a conventional structure and are used to regulate the flow rate and flow volume of the flowing gas in the air inlet 13 and the second intake pipe 15, and can be adaptively adjusted when each pipe is working.

[0042] As a preferred embodiment of the present invention, preferably, as Figure 9 shown, an air outlet 20 communicating with the inner cavity of the inner tank 2 is provided on the other side of the top of the tank body 1. A flow valve similar to the air inlet 13 (not shown in the prior art) is also provided on the air outlet 20. A first filter screen 21, a second filter screen 22, and a third filter screen 23 are sequentially arranged on the inner wall of the air outlet 20 from high to low in the vertical direction. The mesh densities of the first filter screen 21, the second filter screen 22, and the third filter screen 23 increase in sequence. In summary, the nitrogen gas discharged from the inner tank 2 is filtered and purified by the first filter screen 21, the second filter screen 22, and the third filter screen 23 through layer-by-layer filtration and screening, and the working pressure inside the tank body 1 is changed by discharging the nitrogen gas.

[0043] As a preferred embodiment of the present invention, preferably, as Figure 2 shown, a first fixing plate 24 is fixedly arranged on the other side of the inner cavity of the tank body 1. A plurality of second springs 25 are equidistantly arranged on the plate surface of the first fixing plate 24. The second springs 25 are elastically connected to a buffer block 26. By driving the buffer block 26 to move back and forth through the elastic deformation of the second springs 25, buffer protection can be provided for one side of the tank body 1, thereby improving the anti-collision performance of the tank body 1.

[0044] As a preferred embodiment of the present invention, preferably, as Figure 7 shown, a heat preservation layer 27 and a wear-resistant layer 28 are sequentially arranged on the outer wall of the tank body 1 from inside to outside. The heat preservation layer 27 is composed of a nano thermal insulation felt layer and a refractory fiber insulation felt layer. The heat preservation layer 27 can perform heat preservation work on the inner tank 2 to prevent heat loss to the outside, and can reduce the temperature of the outer surface of the tank body 1, reduce heat loss, and improve the heat preservation efficiency and heat utilization rate of the tank body 1.

[0045] As a preferred embodiment of the present invention, preferably, as Figure 1 shown, lifting rings 29 are fixedly connected to both the front end and the rear end sides of the tank body 1. The lifting rings 29 are provided to facilitate the lifting of the tank body 1 by an external lifting device, thereby realizing the rapid handling and movement of the tank body 1.

[0046] As a preferred embodiment of the present invention, preferably, as Figure 1As shown in the figure, two sets of mounting rods 30 are provided in the middle of the front end of the tank body 1. A pressure gauge 31 is fixedly connected to one set of mounting rods 30, and a thermometer 32 is fixedly connected to the other set of mounting rods 30. Through the pressure gauge 31 (which has its own detection mechanism, the specific module and structure of which are not shown in the prior art), the real-time working pressure and pressure change inside the inner tank 2 can be detected. Through the thermometer 32 (which has its own detection mechanism, the specific module and structure of which are not shown in the prior art), the real-time working temperature and temperature change inside the inner tank 2 can be detected.

[0047] As a preferred embodiment of the present invention, preferably, as Figure 8 shown, a second fixing plate 33 is fixedly connected to the top of the tank body 1 on one side of the air outlet 20. A pair of rotating seats 34 are fixedly connected to the plate surface of the second fixing plate 33. A rotating rod 35 is rotatably arranged on the pair of rotating seats 34. A tank door 36 adapted to the tank body 1 is fixedly connected to the rotating rod 35. A sealing gasket 37 adapted to the inner tank 2 is arranged inside the tank door 36. A motor 38 is fixedly connected to the end of the rotating rod 35. During specific implementation, when the motor 38 is turned on, the motor 38 drives the rotating rod 35 to rotate on the rotating seat 34, thereby controlling the rotation of the tank door 36 to open the tank body 1. In addition, when the tank door 36 closes the tank body 1, the sealing performance when the tank body 1 is closed can be improved through the sealing gasket 37.

[0048] As a preferred embodiment of the present invention, preferably, as Figure 1 、 Figure 6 、 Figure 11 shown, mounting blocks 39 are fixedly connected to both sides of the bottom of the tank body 1. An installation plate 40 is arranged below the mounting blocks 39. A hydraulic cylinder 41 is arranged between the mounting blocks 39 and the installation plate 40. The installation plate 40 is connected to an assembly plate 42 through a buffer mechanism arranged below it. A number of assembly bolts 43 are equidistantly arranged on both sides of the assembly plate 42. During specific implementation, the tank body 1 is fixedly installed at the installation station by sequentially driving the assembly bolts 43 onto the assembly plate 42, and the working height of the tank body 1 can be adjusted according to the working conditions by opening the hydraulic cylinder 41.

[0049] As a preferred embodiment of the present invention, preferably, as Figure 10As shown in the figure, the buffer mechanism includes a buffer column 44 fixedly arranged at the bottom of the mounting plate 40. Below the buffer column 44, there is a buffer cylinder 45 fixedly connected to the assembly plate 42. At the axial center of the top of the buffer cylinder 45, there is a buffer hole 46 that is slidably connected to the buffer column 44. The buffer column 44 slidably extends into the inner cavity of the buffer cylinder 45 through the buffer hole 46 and is fixedly connected to a buffer plate 47. The buffer plate 47 is slidably connected to the inner cavity of the buffer cylinder 45. At equal intervals at the bottom end of the buffer plate 47, there are a number of third springs 48. When the device is working as a whole, a certain degree of vibration load will be generated. At this time, through the up and down movement of the buffer column 44 along the buffer hole 46 in the buffer cylinder 45 and the synchronous elastic expansion and contraction of the third springs 48 on the buffer plate 47, the vibration load is damped and buffered, further reducing the impact of the vibration load on the whole device, improving the anti-vibration performance and ensuring the stability of the normal hot pressing work of the device at the same time.

[0050] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
