Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pressure vessel technology, specifically relating to an energy-saving laminated glass pressure vessel that can realize the cascade utilization of waste heat. Background Technology
[0002] Laminated glass is a glass product made by sandwiching two or more layers of glass with an organic material between them, and then pressing them under heat. In the production process of laminated glass, the lamination process and the glass preheating and pre-pressing process are all completed in an autoclave, which is a crucial step in the laminated glass manufacturing process. During the operation of the autoclave, there are heating and cooling processes. The heating process requires electric heating equipment to heat the ambient temperature gas to meet the high-temperature and high-pressure operating conditions, resulting in high energy consumption for the entire autoclave. Currently, the widely used cooling method involves heat exchange between cooling water and high-temperature gas. After heat exchange, the temperature of the cooling water increases significantly, and most factories directly discharge it or use it in scenarios with extremely low requirements for water temperature and quality. The large amount of heat energy carried by the cooling water is not effectively utilized, resulting in energy waste. Utility Model Content
[0003] The purpose of this invention is to provide an energy-saving laminated glass autoclave that can realize the cascade utilization of waste heat, and can recycle the heat absorbed by the cooling water to reduce energy waste.
[0004] To achieve the above objectives, this utility model provides an energy-saving laminated glass pressure vessel capable of cascaded utilization of waste heat. The vessel includes a vessel body, with a fan and a vessel door connected to both ends. The vessel body is equipped with guide rails and a heating device.
[0005] The vessel body has an outer wall and an inner wall, with a sandwich layer between the outer wall and the inner wall. The sandwich layer is filled with heat storage material and has high-temperature cooling water pipelines and preheating air pipelines. The inlet and outlet of the high-temperature cooling water pipelines pass through the outer wall and are located on the outside of the vessel body. The inlet and outlet of the preheating air pipelines also pass through the outer wall and are located on the outside of the vessel body.
[0006] The vessel is equipped with a heat exchange plate. A cooling water pipe is installed between the heat exchange plate and the inner wall through a pipe support. The inlet and outlet of the cooling water pipe both pass through the vessel body and are located on the outside of the vessel body.
[0007] The vessel body is equipped with a water storage tank, a cooling water pump, and an air pump. The water storage tank is connected to the water inlet through the cooling water pump. The water outlet is equipped with a temperature sensor and is divided into two paths: one path is directly connected to the water storage tank, and the other path is connected to the water inlet. The water outlet is connected to the water storage tank. The air pump is connected to the air inlet through an air pipeline.
[0008] The pressure vessel is also equipped with a control system for controlling the operation of the pressure vessel.
[0009] As a further embodiment of this utility model: the vessel body is horizontal, with a base connected to the bottom, and a guide rail is horizontally positioned at the bottom of the vessel body.
[0010] As a further embodiment of this utility model: the heating device is positioned on the top of the vessel body along the corresponding guide rail.
[0011] As a further embodiment of this utility model, the heat exchange plates are provided in two sets, symmetrically distributed on both sides of the guide rail.
[0012] As a further embodiment of this utility model, a pressure relief valve is provided on the vessel body to connect the inside and outside of the vessel body.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. The outlet of the cooling water pipe is monitored and judged by a temperature sensor. The cooling water path can be selected according to the cooling water temperature at the outlet, so as to make better use of the heat carried by the cooling water and to recycle the heat absorbed by the cooling water, thereby reducing energy waste.
[0015] 2. By setting up a jacket between the outer and inner walls of the vessel body and filling the jacket with heat storage material, the heat carried by the cooling water can be stored, and this heat can be used to preheat the air in the preheating air pipeline for use in the next operation of the vessel body.

[0020] The present invention will be further described below with reference to the accompanying drawings.
[0021] like Figure 1 and Figure 2 As shown, an energy-saving laminated glass pressure vessel that can realize the cascade utilization of waste heat includes a vessel body 1, with a blower 24 and a vessel door 6 connected to both ends of the vessel body 1 respectively. The vessel body 1 is equipped with a guide rail 7 and a heating device 2, preferably using electric heating.
[0022] The vessel body 1 has an outer wall 1.1 and an inner wall 1.2. The outer wall 1.1 is provided with a heat insulation layer. An interlayer 1.3 is provided between the outer wall 1.1 and the inner wall 1.2. The interlayer 1.3 is filled with heat storage material and is equipped with a high-temperature cooling water pipe 22 and a preheating air pipe 23. The inlet 19 and outlet 20 of the high-temperature cooling water pipe 22 pass through the outer wall 1.1 and are located on the outside of the vessel body 1. The inlet 17 and outlet 11 of the preheating air pipe 23 pass through the outer wall 1.1 and are located on the outside of the vessel body 1.
[0023] A heat exchange plate 3 is provided inside the vessel body 1. A cooling water pipe 5 is installed between the heat exchange plate 3 and the inner wall 1.2 through a pipe support 4. The inlet end 10 and outlet end 21 of the cooling water pipe 5 both pass through the vessel body 1 and are located on the outside of the vessel body 1.
[0024] The vessel body 1 is equipped with a water storage tank 14, a cooling water pump 12, and an air pump 13. The water storage tank 14 is connected to the water inlet 10 through the cooling water pump 12. The water outlet 21 is equipped with a temperature sensor 16 and is divided into two paths: one path is directly connected to the water storage tank 14, and the other path is connected to the water inlet 19. The water outlet 20 is connected to the water storage tank 14. The air pump 13 is connected to the air inlet 17 through an air pipe 15.
[0025] A temperature value is preset, and the temperature sensor 16 monitors it. If the cooling water temperature at the outlet 21 is higher than the set temperature value, the high-temperature cooling water pipeline 22 is selected; otherwise, it is directly sent into the water storage tank 14.
[0026] The vessel body 1 is also equipped with a control system 9 for controlling the operation of the pressure vessel. The control system 9 includes a power switch, temperature and time settings, a pressure relief valve switch, and a vessel door control switch, which facilitates the operation of the pressure vessel.
[0027] Furthermore, the vessel body 1 is horizontal, with a base 8 connected to the bottom, and a guide rail 7 is horizontally located at the bottom of the vessel body 1. The guide rail 7 facilitates the entry and exit of the vehicle carrying the glass.
[0028] Furthermore, the heating device 2 is positioned at the top of the vessel body 1, corresponding to the guide rail 7.
[0029] Furthermore, the heat exchange plates 3 are provided in two sets, symmetrically distributed on both sides of the guide rail 7, making full use of the space inside the vessel body 1, and together with the cooling water pipes 5, etc., they can carry out stable heat exchange operations.
[0030] To ensure the safety of the vessel body 1, a pressure relief valve 18 connecting the inside and outside of the vessel body 1 is further provided.
[0031] When using this utility model, after pushing the car containing the glass into the vessel body 1 and closing the vessel door 6, the temperature and holding time for processes such as heating, preheating, depressurization and exhaust are set, the pressure vessel is started, and the heating device 2 raises the temperature of the air injected into the vessel body 1 to reach the set value and holds it for a period of time.
[0032] Then, a cooling device consisting of a cooling water pump 12, a cooling water pipe 5, and a heat exchange plate 3 is used to cool down the glass and film quickly, ensuring product quality and performance.
[0033] The temperature of the cooling water is monitored in real time by the temperature sensor 16 installed on the outlet 21 of the cooling water pipe 5. If the cooling water temperature is higher than the set value, it enters the high-temperature cooling water pipe 22 to supply heat to the heat storage material. The heat stored in the heat storage material can preheat the next batch of air injected into the vessel 1 (the next batch of air injected into the vessel 1 can be sent into the preheating air pipe 23 by the air pump 13). The cooled water after heat exchange is injected into the water storage tank 14. If the temperature of the cooling water at the outlet 21 is lower than the set value, it is directly injected into the water storage tank 14.
[0034] The cooling water in the water storage tank 14 can be used not only for circulating cooling of the pressure vessel, but also as a heat source for the water source heat pump heating system.
