As shown in fig. 1 to 6, the present invention provides an autoclave comprising a control system, an autoclave body 10, a first mechanical pump 20, a second mechanical pump 30, a first air pump 40, a second air pump 50 and a valve structure 60.

The cauldron body 10 is along transversely setting up subaerial, and the inside of cauldron body 10 has the same first cavity 11 of specification and second cavity 12, and first cavity 11 and second cavity 12 separate through baffle 13. Wherein, the first cavity 11 forms a first opening 14 at one end of the kettle body 10, and a first kettle cover 16 for opening and/or closing the first opening 14 is installed at the above one end of the kettle body 10. The second chamber 12 forms a second opening 15 at the other end of the kettle body 10, and a second kettle cover 17 for opening and/or closing the second opening 15 is installed at the other end of the kettle body 10. Specifically, the first kettle cover 16 and the second kettle cover 17 are provided with a pressure gauge, a gas-liquid phase valve, a temperature sensor and the like, so that the conditions in the kettle can be conveniently known at any time, the safe operation of the high-pressure kettle is ensured, and the structures on the kettle covers belong to the prior art. Other structures in the first cavity 11 and the second cavity 12 are the same as those in the existing autoclave, such as a heating plate, a cooling system, a vent valve, and the like.

The inlet of the first mechanical pump 20 is communicated with the first cavity 11, the outlet of the first mechanical pump is communicated with the outside, the inlet of the second mechanical pump 30 is communicated with the second cavity 12, the outlet of the second mechanical pump 30 is communicated with the outside, and the first mechanical pump 20 and the second mechanical pump 30 are respectively used for vacuumizing the first cavity 11 and the second cavity 12 during operation. The first air pump 40 is installed at one side of the autoclave body 10, an inlet of the first air pump 40 is communicated with the first cavity 11 through a first pipeline 41, an outlet of the first air pump 40 is communicated with the second cavity 12 through a second pipeline 42, and when the first air pump 40 works, all gas in the first cavity 11 can be pumped into the second cavity 12. The inlet of the second air pump 50 is communicated with the second cavity 12 through a third pipeline 51, the outlet of the second air pump 50 is communicated with the second cavity 12 through a four-pipeline outlet, and when the second air pump 50 works, all the gas in the second cavity 12 can be pumped into the first cavity 11.

The valve structure 60 is mounted on each of the first and

third pipes

41 and 51. The valve structure 60 on the first conduit 41 is used to open and/or close the first conduit 41 and the valve structure 60 on the third conduit 51 is used to open and/or close the third conduit 51.

The first mechanical pump 20, the second mechanical pump 30, the first air pump 40, the second air pump 50, the valve structure 60, the first kettle cover 16 and the second kettle cover 17 are all electrically connected with the control system.

The specific working process is as follows: the worker firstly transports two batches of laminated glass into the first cavity 11 and the second cavity 12 through a glass car respectively, and closes the first kettle cover 16 and the second kettle cover 17. The heating plate in the first cavity 11 processes the laminated glass therein, and the laminated glass is subjected to five stages of preheating, temperature and pressure rise, heat and pressure preservation, temperature and pressure reduction and exhaust. When the exhaust stage is reached, the second mechanical pump 30 starts to work, the second cavity 12 is subjected to vacuum treatment, then the valve structure 60 on the first pipeline 41 is opened, the first air pump 40 pumps all the hot air in the first cavity 11 into the second cavity 12, and the laminated glass in the second cavity 12 is preheated. Finally, the valve structure 60 of the first duct 41 is closed to prevent the reverse flow of the hot air. This design introduces the hot air that should be discharged to the outside into the second cavity 12, so that the heat exchange plates in the second cavity 12 do not need to be heated to the preheating temperature, and the hot air introduced from the first cavity 11 is enough to preheat the laminated glass in the second cavity 12.

After the valve structure 60 on the first pipeline 41 is closed, the vent valve of the first cavity 11 on the kettle body 10 is opened, so that the first cavity 11 is communicated with the outside, the first kettle cover 16 is opened, the processed laminated glass is taken out, a new batch of laminated glass is put into the first cavity 11, and then the first kettle cover 16 is closed. The first mechanical pump 20 starts to operate to vacuumize the first cavity 11, and then opens the valve structure 60 and the second air pump 50 on the third pipeline 51 to draw the hot air in the second cavity 12, which goes to the exhaust stage, into the first cavity 11 again, so as to preheat another batch of new laminated glass. Finally, the valve structure 60 of the third duct 51 is closed to prevent the reverse flow of the hot air. This also eliminates the need for the heat exchanger plates in the second chamber 12 to be heated to a preheating temperature, and the introduction of hot air from the second chamber 12 is sufficient to preheat a new batch of laminated glass in the first chamber 11. And finally, opening a vent valve of the second cavity 12 on the kettle body 10 to enable the second cavity 12 to be communicated with the outside, opening the second kettle cover 17, taking out the processed laminated glass, putting a new batch of laminated glass into the second cavity 12, and circularly working in the way.

The repeated cooperation of the first air pump 40, the second air pump 50 and the valve structure 60 can repeatedly and circularly pump the hot air entering the exhaust stage into another cavity, so that the laminated glass in the other cavity is preheated, the hot air in the autoclave cannot run off in vain when the exhaust stage is carried out, and the waste of heat sources is reduced.

In one embodiment, the first chamber 11 may have a higher gas pressure as the first chamber 11 proceeds to the exhaust stage. While the second chamber 12 is now under vacuum by the second mechanical pump 30. Due to the communication between the first conduit 41 and the second conduit 42, a large pressure difference exists between the two sides of the valve structure 60 on the first conduit 41. The pressure difference may cause a large friction between the valve plate 61 and the first conduit 41 when the valve plate 61 is opened, which is inconvenient for opening the valve plate 61, and may cause the valve plate 61 to partially move in the lateral direction, which may cause air leakage, which is unfavorable for sealing the valve structure 60.

To solve the above problems. The valve structure 60 includes a valve plate 61 and a guide rod 62, and the valve plate 61 is disposed above the first duct 41 or the third duct 51. The valve plate 61 may be longitudinally inserted into the first or

third duct

41 or 51 through the notch 413 of the first or

third duct

41 or 51 to close the first or

third duct

41 or 51. During the longitudinal movement of the valve plate 61, the valve plate 61 is always in a sealing connection with the first conduit 41 or the third conduit 51.

The two guide rods 62 are fixedly arranged at two ends of the valve plate 61 along the longitudinal direction, and the guide rods 62 guide the movement of the valve plate 61. Taking the valve structure 60 on the first pipe 41 as an example, when the first chamber 11 is in the exhaust stage, the second chamber 12 is in the vacuum state under the operation of the second mechanical pump 30. There will be a large difference in air pressure between the left and right sides of the valve plate 61 in the first conduit 41, and the valve plate 61 will be forced to the right, tending to move to the right. Due to the limiting action of the guide rod, the guide rod can generate a leftward reaction force on the valve plate, so that the air pressure difference between the two sides of the valve plate 61 is offset. The valve plate 61 is prevented from generating friction force with the first pipeline 41 when moving longitudinally, and the abrasion between the valve plate 61 and the first pipeline 41 is reduced. The valve plate 61 is also not displaced laterally, facilitating sealing of the valve structure 60.

The valve structure 60 of the third pipe 51 is the same as the valve structure 60 of the first pipe 41, and will not be described herein.

In one embodiment, the upper end of the first conduit 41 or the third conduit 51 is grooved with an annular groove 412. The valve plate 61 is positioned inside the annular groove 412, and the upper end of the valve plate 61 is fixedly provided with a sealing ring 80 which is matched with the annular groove 412. When valve plate 61 is inserted into first conduit 41 or third conduit 51, sealing ring 80 is just inserted into groove 412. The design of the groove 412 and the sealing ring 80 enables the valve structure 60 to better seal the first pipe 41 and the third pipe 51, and avoid gas leakage.

In one embodiment, the first conduit 41 has a first slot 411 formed therein for accommodating the valve plate 61. The cooperation of the valve plate 61 and the first slot 411 increases the contact area of the valve plate 61 and the first pipeline 41, and further improves the sealing effect of the valve structure 60 on the first pipeline 41.

In one embodiment, the third conduit 51 has a second slot 511 formed therein to accommodate the valve plate 61. The cooperation of the valve plate 61 and the second slot 511 increases the contact area of the valve plate 61 with the third pipeline 51, and further improves the sealing effect of the valve structure 60 on the third pipeline 51.

In one embodiment, a cylinder 70 is also included, disposed longitudinally. Preferably, a cylinder 70 is installed at both sides of the valve plate 61. The piston rod of each cylinder 70 is fixedly connected with the valve plate 61, and the cylinders 70 are electrically connected with the control system. The control system can control the lifting of the valve plate 61 by controlling the cylinder 70, and further control the opening and closing of the valve structure 60. The automation degree is improved, and the labor intensity of workers is reduced.
