Description

Technical Field

[0001] This application relates to the field of glass processing equipment, and in particular to a ventilation structure for a laminated glass autoclave. Background Technology

[0002] An autoclave is a piece of equipment used to produce laminated glass. It primarily utilizes high pressure to compress the air in the PVB film (interlayer) between the glass layers. The process involves first placing the assembled glass-film-glass assembly into the autoclave. A heating system raises the internal temperature to a specific range, softening and making the interlayer adhesive. Then, compressed air or other gases are used to apply high pressure to the autoclave. Under this high temperature and pressure, the softened interlayer adheres fully to the glass surface. Simultaneously, the softened interlayer expels any residual air between the layers. Finally, cooling allows the film to bond seamlessly with the laminated glass.

[0003] Chinese Patent No. CN202865122U discloses a wind stirring device for a glass autoclave, including a motor. The motor drives a fan impeller installed inside the glass autoclave to rotate via a drive shaft. The drive shaft outside the glass autoclave shell is installed in a heat dissipation sleeve. The inner wall of the heat dissipation sleeve is provided with a cold water circulation pipe. A graphite ring is fitted on the drive shaft between the motor and the heat dissipation sleeve.

[0004] During the use of the above technology, since the fan impeller is located at one end of the autoclave and the autoclave is a closed environment, when the fan impeller rotates and generates airflow, the airflow at the end of the autoclave away from the fan impeller is poor, resulting in uneven air temperature distribution inside the autoclave, which in turn affects the production quality of laminated glass and has shortcomings. Utility Model Content

[0005] In order to improve the problem that uneven air temperature distribution in the autoclave affects the production quality of laminated glass in the above-mentioned technology, this application provides a ventilation structure for a laminated glass autoclave.

[0006] The ventilation structure for a laminated glass autoclave provided in this application adopts the following technical solution: A ventilation structure for a laminated glass autoclave includes a hollow autoclave body with one open end. A lid is hinged to the open end of the autoclave body. An inner cylinder, also hollow and open at one end, is disposed inside the autoclave body. An end ring plate is provided between the open end of the inner cylinder and the open end of the autoclave body. Partition strips are provided on both sides of the bottom of the inner cylinder, dividing the cavity between the autoclave body and the inner cylinder into a top chamber and a bottom chamber. Several side through holes and several bottom through holes are provided between the inner and outer walls of the inner cylinder. The side through holes connect the inner cavity of the inner cylinder to the top chamber, and the bottom through holes connect the inner cavity of the inner cylinder to the bottom chamber. An electric heater, electrically connected to a control system, is disposed on the inner cylinder and located within the top chamber. A circulation assembly is disposed on the autoclave body to allow air to flow from the top chamber to the bottom chamber.

[0007] By adopting the above technical solution, when heating is required, the control system starts the electric heater, which heats the top chamber. The circulation component causes the air in the top chamber to flow to the bottom chamber, and the air in the bottom chamber flows into the inner cylinder through the bottom through hole. The air inside the inner cylinder flows into the top chamber through the side through hole. During this process, the heated air in the top chamber is constantly circulating, which makes the air temperature in all parts of the inner cylinder gradually become more uniform, thereby improving the production quality of laminated glass.

[0008] Optionally, the circulation assembly includes a circulation pipe disposed on the vessel body, one end of the circulation pipe communicating with the top chamber at the top of the vessel body and the other end communicating with the bottom chamber at the bottom of the vessel body, and a circulation air pump electrically connected to the control system is disposed on the circulation pipe.

[0009] By adopting the above technical solution, the control system starts the circulating air pump, which circulates the air in the top and bottom chambers through the circulation pipe, thereby achieving a uniform air temperature throughout the inner cylinder.

[0010] Optionally, a V-shaped baffle is provided at the bottom of the inner cylinder and within the bottom cavity, and one end of the circulation pipe that communicates with the bottom cavity points to the V-shaped end of the baffle.

[0011] By adopting the above technical solution, during the process of hot air flowing into the bottom cavity from the circulation pipe, the baffle will divert the hot air. The diverted hot air will diffuse in the bottom cavity, thereby making the air temperature in the bottom cavity gradually more uniform, which is beneficial to improving the temperature uniformity in the inner cylinder.

[0012] Optionally, a plurality of support plates are provided between the outer side wall of the inner cylinder and the inner side wall of the vessel body. The support plates are located in the top cavity. The plurality of support plates are arranged along the length direction of the vessel body. A plurality of electric heaters are arranged on the inner cylinder. The electric heaters are located on both sides of the support plates.

[0013] By adopting the above technical solution, the top chamber is divided into multiple cavities by multiple support plates, and multiple cavities are heated simultaneously by multiple electric heaters. This greatly reduces the time required to heat the air inside the inner cylinder. At the same time, multiple electric heaters help to shorten the time when the temperature is uneven in different parts of the inner cylinder in the initial stage, which is beneficial to improving the production quality of laminated glass.

[0014] Optionally, the vessel body is provided with a plurality of cooling coils, which are arranged along the length of the vessel body. The cooling coils are located at the side through holes of the inner cylinder and on both sides of the support plate.

[0015] By adopting the above technical solution, when it is necessary to cool the air inside the inner cylinder, the control system stops the electric heater and supplies cooling water to the cooling coil. As the air flows through the side opening, heat exchange occurs between the air and the surface of the cooling coil, thereby continuously reducing the air temperature inside the inner cylinder. At the same time, multiple cooling coils can greatly shorten the time required for the air temperature inside the inner cylinder to decrease, which is beneficial to improving the production efficiency of laminated glass.

[0016] Optionally, the side through hole is formed on the vertical side wall of the inner cylinder, and the electric heater is located above the side through hole.

[0017] By adopting the above technical solution, it is beneficial to improve the efficiency of the heat generated on the electric heater being rapidly diffused into the air inside the vessel.

[0018] Optionally, the vessel body is provided with an internal flow valve and an external flow valve, both of which are electrically connected to the control system, and both of which can be detachably provided with hot gas pipes.

[0019] By adopting the above technical solution, when the electric heater inside the reactor is damaged, workers can connect hot air pipes to the internal and external flow valves to continuously raise the temperature of the air inside the reactor, thereby reducing the occurrence of substandard laminated glass production quality due to accidental damage to the electric heater.

[0020] Optionally, a pressure gauge and a temperature gauge are provided on the vessel body, and both the pressure gauge and the temperature gauge are electrically connected to the control system.

[0021] By adopting the above technical solution, the information automatically fed back to the control system through pressure gauges and thermometers is beneficial to improving the intelligence of automatic temperature control in the reactor and improving the consistency of laminated glass production quality.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When heating is required, the control system activates the electric heater, which heats the top chamber. The circulation component causes the air in the top chamber to flow to the bottom chamber. The air in the bottom chamber flows into the inner cylinder through the bottom through-hole, and the air inside the inner cylinder flows into the top chamber through the side through-hole. During this process, the heated air in the top chamber is constantly circulating, which gradually makes the air temperature in all parts of the inner cylinder more uniform, thereby improving the production quality of laminated glass. 2. As hot air flows into the bottom cavity through the circulation pipe, the baffle will split the hot air. The split hot air will diffuse in the bottom cavity, thereby making the air temperature in the bottom cavity gradually more uniform, which is beneficial to improving the temperature uniformity in the inner cylinder. 3. When the electric heater inside the reactor is damaged, workers can connect hot air pipes to the internal and external flow valves to continuously raise the temperature of the air inside the reactor, reducing the occurrence of substandard laminated glass production quality due to accidental damage to the electric heater.

[0027] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0028] This application discloses a ventilation structure for a laminated glass autoclave.

[0029] Reference Figure 1 A ventilation structure for a laminated glass autoclave includes an autoclave body 1 that is hollow inside and open at one end. An autoclave cover 2 is hinged to the open end of the autoclave body 1. An internal flow valve 15 and an external flow valve 16 are bolted to the autoclave body 1. Both the internal flow valve 15 and the external flow valve 16 are electrically connected to a control system. Hot air pipes 17 are bolted to both the internal flow valve 15 and the external flow valve 16.

[0030] Reference Figure 1 , Figure 2 and Figure 3 Pressure gauge 18 and temperature gauge 19 are bolted to the vessel body 1. Both pressure gauge 18 and temperature gauge 19 are electrically connected to the control system. The interior of the vessel body 1 is arranged with an inner cylinder 3 that is hollow inside and open at one end. An end ring plate 4 for sealing is welded between the open end of the inner cylinder 3 and the open end of the vessel body 1. Partition strips 5 are welded to both sides of the bottom of the inner cylinder 3.

[0031] Reference Figure 2 and Figure 3 Two partition strips 5 divide the cavity between the inner wall of the vessel body 1 and the outer wall of the inner cylinder 3 into a top chamber 6 and a bottom chamber 7. The top chamber 6 is located above the bottom chamber 7. Several side through holes 8 and several bottom through holes 9 are provided between the inner and outer walls of the inner cylinder 3. The side through holes 8 connect the internal cavity of the inner cylinder 3 with the top chamber 6, and the bottom through holes 9 connect the internal cavity of the inner cylinder 3 with the bottom chamber 7.

[0032] Reference Figure 1 , Figure 2 and Figure 3 Multiple electric heaters 10, which are electrically connected to the control system, are bolted to the inner cylinder 3 and located in the top chamber 6. The side through hole 8 is opened on the vertical side wall of the inner cylinder 3, and the electric heaters 10 are located above the side through hole 8. A circulation assembly 11 is arranged on the vessel body 1. The circulation assembly 11 is used to make the air in the top chamber 6 flow into the bottom chamber 7.

[0033] Reference Figure 2 and Figure 3 The circulation assembly 11 includes a circulation pipe 111 with a flange connected to the vessel body 1. A circulation air pump 112, which is electrically connected to the control system, is connected to the flange on the circulation pipe 111. One end of the circulation pipe 111 is connected to the top chamber 6 at the top of the vessel body 1, and the other end is connected to the bottom chamber 7 at the bottom of the vessel body 1. A baffle plate 12 with a V-shaped cross section is welded to the bottom of the inner cylinder 3 and located in the bottom chamber 7. The end of the circulation pipe 111 that is connected to the bottom chamber 7 points to the V-shaped end of the baffle plate 12.

[0034] When it is necessary to heat the air inside the vessel 1, the control system starts the electric heater 10 and the circulating air pump 112. The electric heater 10 heats the air in the top chamber 6, and the circulating air pump 112 draws the air in the top chamber 6 to the bottom chamber 7 through the circulating pipe 111. The air in the bottom chamber 7 flows into the interior of the inner cylinder 3 through the bottom through hole 9, and the air inside the inner cylinder 3 flows into the top chamber 6 through the side through hole 8, thereby continuously raising the temperature of the air inside the inner cylinder 3.

[0035] Reference Figure 2 and Figure 3 Multiple support plates 13 are welded between the outer wall of the inner cylinder 3 and the inner wall of the vessel body 1. The support plates 13 are located in the top chamber 6. The multiple support plates 13 are arranged along the length of the vessel body 1. Multiple electric heaters 10 are arranged on the inner cylinder 3. The electric heaters 10 are located on both sides of the support plates 13.

[0036] Reference Figure 1 , Figure 2 and Figure 3 Multiple cooling coils 14 are bolted to the vessel body 1. Both ends of the cooling coils 14 extend to the outside of the vessel body 1. The multiple cooling coils 14 are arranged along the length of the vessel body 1. The cooling coils 14 are located at the side through holes 8 of the inner cylinder 3. The cooling coils 14 are located on both sides of the support plate 13.

[0037] As hot air flows into the bottom chamber 7 through the circulation pipe 111, the baffle 12 diverts the hot air, which then diffuses within the bottom chamber 7, gradually bringing the air temperature in all parts of the bottom chamber 7 into a uniform state. The multiple electric heaters 10 and multiple circulating air pumps 112 enable the air temperature in all parts of the vessel body 1 along its length to rise rapidly, thereby shortening the time that uneven temperatures exist in different parts of the vessel body 1. Rapid and uniform heating improves the production quality of laminated glass.

[0038] The implementation principle of the ventilation structure of the laminated glass autoclave in this application embodiment is as follows: When it is necessary to heat the air in the autoclave 1, the control system starts the electric heater 10 and the circulating air pump 112. The electric heater 10 heats the air in the top chamber 6, and the circulating air pump 112 draws the air in the top chamber 6 to the bottom chamber 7 through the circulating pipe 111. The air in the bottom chamber 7 flows into the interior of the inner cylinder 3 through the bottom through hole 9, and the air inside the inner cylinder 3 flows into the top chamber 6 through the side through hole 8, thereby continuously raising the temperature of the air in the inner cylinder 3.

[0039] As hot air flows into the bottom chamber 7 through the circulation pipe 111, the baffle 12 diverts the hot air, which then diffuses within the bottom chamber 7, gradually bringing the air temperature in all parts of the bottom chamber 7 into a uniform state. The multiple electric heaters 10 and multiple circulating air pumps 112 enable the air temperature in all parts of the vessel body 1 along its length to rise rapidly, thereby shortening the time that uneven temperatures exist in different parts of the vessel body 1. Rapid and uniform heating improves the production quality of laminated glass.
