Description

Technical Field

[0001] This utility model relates to the technical field of membrane surface drying equipment, and more specifically, to an energy-saving oven-type drying chamber. Background Technology

[0002] In the membrane material production process, after the membrane surface is coated with solvent, it needs to be cured by drying and heating. This step places high demands on the thermal efficiency, structural compactness, and drying uniformity of the drying equipment. The existing traditional drying equipment works as follows: first, solvent is coated on the membrane surface, then circulating air is heated by a heater, and the hot air is transported to the air chamber inside the drying oven by a circulating fan through external air ducts. Finally, the air chamber distributes the hot air to each nozzle and blows it onto the membrane surface to complete the solvent heating and curing. At the same time, the volatile waste gas is discharged from the chamber by an exhaust fan.

[0003] However, the system duct is exposed to the outside of the oven. During the process of transporting the heated air through the duct, the heat is easily lost to the outside through the outer wall of the duct, resulting in low energy utilization and increased production energy consumption. External air ducts require additional space and complex mounting brackets, resulting in a large overall equipment size and a scattered layout, which is not conducive to the efficient use of workshop space. When hot air is transported through external air ducts, temperature loss is likely to occur, resulting in unstable hot air temperature entering the oven. This leads to uneven heating of different areas on the membrane surface, affecting the solvent curing quality and potentially causing incomplete or over-curing in certain areas. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides an energy-saving oven for drying, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: an energy-saving, closed-type drying oven, including a base, on which a drying treatment component is provided; The drying process assembly includes a drying chamber disposed on top of the base, a pad at the bottom of the inner cavity of the drying chamber, a support plate on top of the pad, and a conveyor belt on the outside of the support plate.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] This embodiment discloses an energy-saving, enclosed drying oven, which aims to solve the technical problems of heat loss due to exposed air ducts and bulky overall structure in traditional drying equipment. By optimizing the internal structural layout and heat circulation system, it achieves energy-saving and efficient membrane surface drying treatment.

[0015] As attached Figure 1 Appendix Figure 2 As shown, the energy-saving oven is supported by a base 1. The drying chamber 2 is fixedly installed on the top of the base 1. The drying chamber 2 adopts a sealed cavity design to reduce heat loss during the heat exchange process.

[0016] As attached Figure 4 As shown, a pad 3 is horizontally laid at the bottom of the inner cavity of the drying chamber 2. The pad 3 is made of high-temperature resistant heat-insulating material, and a tray 4 is attached to its top. The tray 4 is used to support the film material to be dried. A conveyor belt 16 is set on the outside of the tray 4. The conveyor belt 16 is connected to an external drive mechanism to realize the continuous conveying of the film material. Several guide tubes 5 are fixed on the outside of the tray 4, the pad 3, and the conveyor belt 16, respectively. The guide tubes 5 are evenly distributed side by side along the length of the drying chamber 2, and several nozzles 6 are spaced apart on the surface of each guide tube 5. The openings of the nozzles 6 face the conveying path of the film material to be dried to ensure that the hot air can evenly cover the surface of the film material.

[0017] As attached Figure 3As shown, several reinforcing ribs 7 are fixed to the top of the inner cavity of the drying chamber 2. The vertical cross-section of each reinforcing rib 7 is arc-shaped. The arc structure can enhance the structural strength of the top of the drying chamber 2 and reduce the resistance to hot air flow. The two ends of each reinforcing rib 7 are fixedly connected to the crossbars 8. The two crossbars 8 are parallel and horizontally arranged, and the crossbars 8 are fixed to the inner side wall of the drying chamber 2. Several connecting rods 9 are evenly distributed between the two crossbars 8. The two ends of the connecting rods 9 are fixed perpendicularly to the two crossbars 8. Several electric heating plates 10 are sleeved and fixed on the outside of each connecting rod 9. The multiple electric heating plates 10 are arranged side by side along the length of the connecting rods 9 to form a top heating array.

[0018] As attached Figure 1 As shown, a filter box 11 is fixedly installed at the top center of the drying chamber 2. The filter box 11 has a built-in high-temperature resistant filter screen to filter impurities in the hot air. A fan 12 is connected to one side of the filter box 11 via a flange. The air outlet of the fan 12 is connected to the top of the drying chamber 2 to realize the suction and delivery of air. A circulation pipe 13 is welded to the side of the filter box 11 away from the fan 12. One end of the circulation pipe 13 passes through the interior of the base 1 and extends to the bottom of the inner cavity of the drying chamber 2. The outlet of the circulation pipe 13 faces the air inlet of the duct 5, forming a closed heat circulation channel.

[0019] Several inspection doors 14 are hinged to the outer side wall of the drying chamber 2. The positions of the inspection doors 14 correspond to the installation positions of the electric heating plate 10 and the conduit 5, which facilitates later maintenance and component replacement. Several baffles 15 are fixed at the openings at both ends of the drying chamber 2. The bottom end of each baffle 15 extends to the top of the base 1. The baffles 15 are evenly distributed along the edge of the opening to limit the film material during the conveying process and prevent it from shifting.

[0020] The specific working principle is as follows: When in use, the film material to be dried is conveyed to the conveyor belt 16 through the external feeding mechanism. Under the drive of the driving mechanism, the conveyor belt 16 smoothly conveys the film material into the drying chamber 2. The baffles 15 limit the two sides of the film material to ensure that the film material moves along the preset path.

[0021] Start the electric heating plate 10, which quickly heats up and heats the air inside the drying chamber 2; at the same time, start the fan 12, which draws the hot air from the drying chamber 2 into the filter box 11. After the hot air passes through the filter screen inside the filter box 11, impurities and dust in the air are removed to avoid contaminating the surface of the membrane material.

[0022] The filtered hot air is delivered to the bottom of the inner cavity of the drying chamber 2 through the circulation pipe 13 and evenly distributed into each of the ducts 5. Finally, it is blown onto the surface of the membrane material in the form of a uniform airflow through the nozzles 6 on the ducts 5 to heat and cure the solvent on the surface of the membrane material.

[0023] During the heat circulation process, the arc-shaped reinforcing ribs 7 reduce the flow resistance of hot air at the top, making the temperature distribution inside the chamber more uniform; the circulation pipe 13 and the duct 5 are both set inside the drying chamber 2 or the base 1, avoiding the heat evaporation of the external air duct of traditional equipment and greatly reducing energy consumption; at the same time, the compact internal structure layout also solves the problem of the bulkiness of traditional equipment.

[0024] Once the membrane material is dried, it is conveyed out of the drying chamber 2 by the conveyor belt 16, completing the entire drying process. If equipment maintenance is required, the inspection door 14 can be opened to clean or replace components such as the electric heating plate 10, the conduit 5, and the nozzle 6.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
