Description

Technical Field

[0001] This utility model relates to the technical field of fiberglass mesh drying equipment, specifically to a fiberglass mesh thermal oil heating drying furnace. Background Technology

[0002] Fiberglass mesh, also known as fiberglass reinforcing mesh, serves multiple functions in construction. In thin plaster layers, it disperses the tension of the external material across the entire surface, preventing crack formation. In thick plaster layers, it acts as a reinforcement, preventing the movement of inner materials and thus cracking. Alkali-resistant fiberglass mesh is a reinforcing material for exterior wall insulation layers. Its main functions are to improve the mechanical strength of the surface layer, ensure the continuity of the finishing layer's resistance, disperse the shrinkage pressure and insulation stress of the surface layer, avoid stress concentration, and resist surface cracking caused by changes in temperature and humidity and accidental impacts. Fiberglass mesh is made from medium-alkali or alkali-free woven fiberglass fabric with an alkali-resistant coating. Due to its high strength and good alkali resistance, it plays an important structural role in thermal insulation systems, mainly preventing cracks. Fiberglass mesh is also widely used in building interior and exterior walls for thermal insulation, waterproofing, fireproofing, and crack resistance. Alkali-resistant fiberglass mesh, due to its good chemical stability, high strength, good toughness, and good positioning properties, is mainly used as a wall reinforcement material in building exterior and interior wall insulation. The production process of fiberglass mesh requires the use of fiberglass mesh drying equipment.

[0003] In related technologies, a search revealed a double-inlet double-outlet hot air circulating fiberglass mesh drying device, such as publication number CN219797847U. This device includes a drying oven, on both sides of which are symmetrically arranged an impregnation mechanism, a fabric storage rack, and a winding machine. This double-inlet double-outlet hot air circulating fiberglass mesh drying device can be achieved through the cooperation of a fan, a heater, and a hot air delivery duct. This application and this application are from the same applicant.

[0004] However, when using electric heaters for direct heating, the internal heating elements are prone to aging and burnout, requiring frequent replacement of the heating tubes, which makes long-term use inconvenient and maintenance costs high. To solve the above problems, a fiberglass mesh thermal oil heating drying oven is proposed. Utility Model Content

[0005] In view of this, the present invention provides a fiberglass mesh thermal oil heating and drying oven. The present invention supplies heated thermal oil to the heat exchange components through a heating device, thereby causing the surface of the heat exchange tube to dissipate heat energy. The heat energy dissipated by the heat exchange tube is then blown out by a fan. The cooled thermal oil is collected through a recovery pipe and a recovery oil tank, and then added back to the heating oil tank. This process is repeated to achieve recycling, which reduces the aging rate of the heating element, eliminates the need for frequent replacement of the heating tube, facilitates long-term use, and reduces the frequency and cost of daily maintenance.

[0006] To solve the above-mentioned technical problems, this utility model provides a fiberglass mesh thermal oil heating and drying oven, including a fan mounted on a support frame, an insulated oven chamber at the fan outlet, a heating inner chamber fixedly mounted inside the insulated oven chamber, a heat exchange component fixedly mounted in the middle of the heating inner chamber, a heating device at the liquid inlet end of the heat exchange component, a recovery component at the liquid outlet end of the heat exchange component, the recovery component being connected to the heating device, and an insulation cavity between the inner wall of the insulated oven chamber and the outer wall of the heating inner chamber.
