Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of adhesive heating equipment, specifically to a heating system for copper clad laminate production. Background Technology
[0002] Thermosetting resin copper-clad laminates are widely used in electrical / electronic instruments and machinery. The production of these laminates involves first impregnating reinforcing materials (such as sheets of paper or fabric) with liquid resin (thermosetting resins such as epoxy resin, made with solvents or curing agents). The resin-impregnated reinforcing materials are then heated and dried to obtain "prepreg sheets." These prepreg sheets are then stacked, heated, and pressurized to bond them together, forming the thermosetting resin copper-clad laminate. The process of impregnating the reinforcing materials with resin and drying them to form the "prepreg sheets" is completed on an impregnation machine. The heat required for hot pressing and resin application is generally provided by boilers burning natural gas; however, existing heating systems often experience insufficient heat supply.
[0003] Furthermore, the baking process in the dipping machine easily generates a large amount of waste gas, which poses a safety hazard during production due to its flammability and large quantity. Currently, the large amount of organic solvent exhaust gas generated during the baking process must be incinerated in an incinerator before being released. Therefore, the incinerator also needs to be operational during production. However, the incinerator needs to reach a temperature of 760℃ or higher to ensure complete combustion. Directly releasing the remaining heat into the air would cause thermal pollution and fail to meet environmental protection requirements. Summary of the Invention
[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing a heating system for copper clad laminate production that can ensure sufficient heat supply and fully utilize the thermal energy of the incinerator while avoiding thermal pollution.
[0005] The solution adopted by this utility model to solve the technical problem is: a copper-clad laminate production heating system for supplying heat to heat-using equipment, including a thermal oil furnace, an incinerator, a thermal oil furnace steam generator, and a regenerative heat exchanger. The thermal oil furnace has an inlet and an outlet, and the regenerative heat exchanger has a hot inlet, a hot outlet, a cold inlet, and a cold outlet. The outlet of the thermal oil furnace is connected to the hot inlet of the regenerative heat exchanger, and the outlet of the thermal oil furnace is also connected to the heat-using equipment. The inlet of the thermal oil furnace is connected to the cold outlet of the regenerative heat exchanger. The heat-using equipment, the incinerator, and the thermal oil furnace steam generator are sequentially connected between the hot outlet and the cold inlet of the regenerative heat exchanger.
[0006] Furthermore, in order to pump the cooling oil back to the thermal oil furnace for heating, a first oil pump is installed between the inlet of the thermal oil furnace and the cold outlet of the regenerative heat exchanger.
[0007] Furthermore, in order to pump heat energy and ensure the circulation of heat transfer oil, a second oil pump is provided at the front end of the heat outlet of the regenerative heat exchanger, a third oil pump is provided at the front end of the heat-using equipment, and a fourth oil pump is provided at the front end of the incinerator to pump heat energy.
[0008] Furthermore, in order to effectively cool the heat transfer oil during shutdown or other emergencies, the copper clad laminate production heating system also includes a cooling circulation oil circuit, which includes a short-circuit circuit, a first low-level tank, a second low-level tank, and a high-level tank. One end of the short-circuit circuit is connected to the outlet of the thermal oil furnace, and the other end of the short-circuit circuit is connected to the heat-using equipment and the incinerator, and then connected to the first low-level tank. The heat outlet of the regenerative heat exchanger is also connected to the first low-level tank. The first low-level tank and the second low-level tank are connected to each other. The other end of the heat-using equipment is also connected to the second low-level tank. The other end of the second low-level tank is connected to the high-level tank through the fifth oil pump. The other end of the high-level tank is connected to the inlet of the thermal oil furnace.
[0009] Furthermore, in order to achieve high-efficiency production and ensure sufficient heat energy supply when multiple devices work simultaneously, the heat-using equipment includes several sets of hot presses and impregnation machines connected in parallel, and the incinerator has several sets accordingly, with each incinerator connected to each hot press and impregnation machine.
