Description

Technical Field

[0001] This utility model relates to the field of metal sheet production technology, specifically to an oven for manufacturing metal sheets. Background Technology

[0002] The production of sheet metal and drying ovens are closely related, primarily in five aspects: drying operations, improving drying efficiency, automation control, energy conservation and environmental protection, and quality control. In the preparation of sheet metal, drying ovens are used to dry the sheets, reducing surface moisture for easier transportation and storage. Technological advancements have driven the development of automatic vertical drying oven manufacturing processes for metal composite panels, such as the lifting-type layered drying method, which effectively improves drying efficiency. Furthermore, sheet metal drying equipment utilizes automated control systems, including blowers, conveyor belts, sheets, drying chambers, heaters, temperature controllers, exhaust fans, conveyor rollers, motors, and control cabinets, to achieve automatic temperature control and improve drying effects. Regarding energy conservation and environmental protection, oven designs incorporate waste heat recovery and temperature control mechanisms, reducing power consumption and production costs. The oven structure is crucial for the quality control of sheet metal; the uniformity of its cross-sectional temperature directly affects the degree of resin curing, ensuring product quality. Therefore, drying ovens play a vital role in sheet metal production, not only for drying and improving production efficiency but also in energy conservation, environmental protection, and product quality control.

[0003] When drying a large number of metal sheets at once, electrically heated ovens obviously cannot meet the needs of general production. Therefore, we use fuel-fired ovens to dry metal sheets over a large area and with high intensity by burning fuel.

[0004] However, when using a fuel-fired oven for drying, the most important thing to pay attention to is controlling the flame formed by the fuel. If the flame cannot be extinguished in time, it will damage the surface of the board, and if the flame is too large, it will cause burns to the workers' skin.

[0005] Therefore, in view of this, we have studied and improved the existing shortcomings and proposed an oven for the production and manufacturing of metal sheets. Utility Model Content

[0006] The purpose of this invention is to provide an oven for manufacturing metal sheets, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an oven for manufacturing metal sheets, comprising: an oven body, combustion-supporting pipes horizontally penetrating the front and rear ends of the oven body, a fuel nozzle at the front end of the combustion-supporting pipes, a positioning block on the outer side of the front end of the fuel nozzle, air guards on both sides of the front of the positioning block, vertical grooves on the inner side of the air guards, a flame arrestor cylinder in front of the fuel nozzle, a sealing ring sleeved in the middle of the outer side of the flame arrestor cylinder, fire-gathering buckets at the upper and lower ends inside the flame arrestor cylinder, a flame-arresting core in the middle of the flame arrestor cylinder, and a sheet body inside the oven body;

[0008] An auxiliary structure is provided in the middle of the interior of the oven body.

[0009] Furthermore, the outer sealing ring of the flame arrestor is provided with rotating shafts on both sides, which can drive the flame arrestor to rotate. The rotating shafts on both sides of the sealing ring form a sliding structure with the vertical groove, which makes it easy for the flame arrestor to be rotated and moved by the user with fire tongs.

[0010] Furthermore, the upper and lower ends of the positioning block are flush with the edge of the fuel nozzle port, which allows the upper and lower ends of the positioning block to limit the angle at which the user uses the fire tongs, and the positioning block prevents the user from excessively moving the flame arrestor with the fire tongs.

[0011] Furthermore, the windproof plate and the positioning block are fixedly connected to prevent the flame arrestor from falling off.

[0012] Furthermore, the auxiliary structure includes an upper exhaust duct, an internal circulation duct, an air storage plate, an air inlet, and a filter. An air storage plate is vertically arranged in the middle of the oven body. The air storage plate has a cavity inside. A filter is arranged in the middle of the air storage plate. Internal circulation ducts are arranged at the upper ends of both sides of the air storage plate. An upper exhaust duct is arranged at the top of the air storage plate. An air inlet is arranged at the bottom of the air storage plate. The diameter of the upper exhaust duct is not equal to the diameter of the internal circulation duct, which facilitates the differentiation of the amount of hot air discharged from the internal circulation duct and the upper exhaust duct.

[0013] Furthermore, the bottom end of the air storage plate is flush with the bottom end of the plate body after insertion, so that the air inlet can absorb the hot air introduced into the bottom of the oven first.

[0014] Furthermore, the transverse structure of the upper exhaust duct extends to the outside of the oven body, facilitating the exhaust of gas to the outside of the oven.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model involves the combustion of pre-prepared fuel to form a flame that enters a combustion-supporting pipe. The combustion-supporting pipe then ejects the flame through a fuel nozzle. When flame retardancy is required for the fuel nozzle, the user uses pre-prepared fire tongs to move the flame arrestor. Vertical grooves are vertically arranged inside the air guards on both sides of the flame arrestor, and rotating shafts are arranged on both sides of the flame arrestor. When the flame arrestor is moved by the fire tongs, the vertical grooves and the rotating shafts on both sides of the flame arrestor begin to drive the flame arrestor to rotate. The flame-gathering hopper inside the flame arrestor gathers and restricts the flame ejected from the fuel nozzle, so that the flame ejected from the fuel nozzle comes into contact with the flame arrestor core, and the flame ejected from the fuel nozzle is extinguished in time.

[0017] 2. This utility model absorbs air from inside the oven body through the air inlet. The filter inside the air storage plate filters the gas introduced through the air inlet. Additionally, the internal circulation pipe discharges some heat-consistent gas into the outer surface of the oven body, maintaining the oven body temperature at a certain level and preventing it from becoming too cold, which would reduce the drying effect. Simultaneously, the upper exhaust pipe discharges the remaining hot gas, preventing the oven's internal temperature from becoming too high. This design ensures the outer surface of the oven body maintains a certain temperature, continuously insulating the internal material. Furthermore, the upper exhaust pipe removes excess hot air, preventing overheating inside the oven body. Attached Figure Description

Detailed Implementation

[0027] 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.

[0028] like Figures 1-8 As shown, an oven for manufacturing metal sheets includes: an oven body, a combustion-supporting pipe 3 that runs horizontally through the front and rear ends of the oven body, a fuel nozzle 8 that is provided at the front end of the combustion-supporting pipe 3, a positioning block 7 that is provided on the outer side of the front end of the fuel nozzle 8, air guards 4 that are provided on both sides of the front of the positioning block 7, a vertical groove 10 that is provided vertically on the inner side of the air guards 4, a flame arrestor 6 that is provided directly in front of the fuel nozzle 8, a sealing ring 9 that is sleeved in the middle of the outer side of the flame arrestor 6, fire-gathering buckets 11 that are provided at the upper and lower ends inside the flame arrestor 6, a flame arrestor core 12 that is provided in the middle of the flame arrestor 6, and a sheet body 5 that is provided inside the oven body.

[0029] An auxiliary structure 2 is provided in the middle of the interior of the oven body.

[0030] As for the rest, since the flame arrestor 6 is turned by the user using fire tongs, the rotating shafts on both sides of the flame arrestor 6 are turned in conjunction with the vertical grooves 10 set on the inner side of the wind shield 4. At the same time, the rotating shafts on both sides of the flame arrestor 6 can also move up and down inside the vertical grooves 10. The positioning block 7 can prevent the user from excessively turning the flame arrestor 6 with fire tongs. The flame gathering bucket 11 at the end of the flame arrestor 6 near the fuel nozzle 8 can gather the flame. When the flame is gathered by the flame gathering bucket 11, it contacts the flame arrestor core 12. The surface of the flame arrestor core 12 is divided into countless small grid spaces, which will also divide the flame into countless small flames. The flame gathering bucket 11 at the other end of the flame arrestor 6 can extend the combustion path of the flame, thereby achieving the purpose of extinguishing the flame. The user can fix a protrusion on the upper part of the outer side of the flame arrestor 6 to control the angle generated when the flame arrestor 6 is turned.

[0031] This has resulted in the following effects and novel technologies:

[0032] This oven design for metal sheet manufacturing improves the efficiency, quality, and safety of metal sheet drying through its innovative structure and function. The cooperation between the flame arrestor 6 and the positioning block 7 allows the flame arrestor 6 to be moved by fire tongs, while the positioning block 7 prevents excessive turning, enhancing the safety of the drying process. The flame-gathering hopper 11 inside the flame arrestor 6 concentrates the flame and contacts the flame arrestor core 12, dividing the flame into multiple smaller flames, extending the combustion path, and achieving energy-saving effects. The vertical groove 10 on the inner side of the air shield 4 cooperates with the rotating shafts on both sides of the flame arrestor 6, allowing the flame arrestor 6 to turn and move up and down, enhancing... The structural stability is enhanced by the fact that users can control the angle of the flame arrestor 6 when it is moved by a protrusion fixed to the upper outer side of the flame arrestor 6, simplifying operation. In addition, the oven body achieves automatic temperature control, improving work efficiency. Through the waste heat recovery mechanism and temperature control mechanism, the oven effectively improves energy-saving and environmental protection performance, reducing power consumption and production costs. The design of the flame arrestor 6 ensures the uniformity and quality of metal sheet drying. This oven provides an effective drying solution for metal sheet production, taking into account both ease of operation and safety, as well as energy saving, environmental protection, and drying quality.

[0033] like Figures 1-8 As shown, an oven for manufacturing metal sheets includes an auxiliary structure 2 comprising an upper exhaust duct 21, an internal circulation duct 22, an air storage plate 23, an air inlet 24, and a filter 25. An air storage plate 23 is vertically arranged in the middle of the oven body, with a cavity inside. A filter 25 is placed in the middle of the air storage plate 23. Internal circulation ducts 22 are arranged at the upper ends of both sides of the air storage plate 23. An upper exhaust duct 21 is arranged at the top of the air storage plate 23, and an air inlet 24 is arranged at the bottom end of the air storage plate 23. The diameter of the upper exhaust duct 21 is not equal to the diameter of the internal circulation duct 22.

[0034] Furthermore, since the air inlet 24 allows hot air from inside the oven body to be introduced into the air storage plate 23, and the filter 25 filters the hot air, and because the internal circulation pipe 22 is embedded inside the outer surface layer of the oven body, when the internal circulation pipe 22 absorbs some hot air, the outer surface layer of the oven body can still maintain a certain temperature, and the upper exhaust pipe 21 discharges the remaining hot air, so that the internal temperature of the oven body cannot be too high. Users can modify the diameter of the upper exhaust pipe 21 and the internal circulation pipe 22. When the diameter of the internal circulation pipe 22 is larger than the diameter of the upper exhaust pipe 21, the amount of hot air absorbed by the internal circulation pipe 22 is greater than the amount of hot air discharged by the upper exhaust pipe 21. When the diameter of the internal circulation pipe 22 is smaller than the diameter of the upper exhaust pipe 21, the amount of hot air absorbed by the internal circulation pipe 22 is less than the amount of hot air discharged by the upper exhaust pipe 21, thereby controlling the temperature of the outer surface of the oven body and the temperature inside the oven body.

[0035] This has resulted in the following effects and novel technologies:

[0036] The design of this oven for metal sheet manufacturing achieves precise temperature control and effective heat management through the innovative auxiliary structure 2. Auxiliary structure 2 includes an upper exhaust duct 21, an internal circulation duct 22, an air storage plate 23, an air inlet 24, and a filter 25. The air inlet 24 guides hot air from inside the oven body into the air storage plate 23. The filter 25 filters the hot air. The internal circulation duct 22 absorbs some of the hot air, and the upper exhaust duct 21 discharges the remaining hot air, preventing excessive heat buildup inside the oven body. The air storage plate 23 has an internal cavity with a filter 25 in the middle, internal circulation ducts 22 on both upper sides, an upper exhaust duct 21 at the top, and an air inlet 24 at the bottom. This optimizes the hot air flow path and improves heat exchange efficiency. Users can adjust the upper exhaust duct as needed. The diameters of pipe 21 and internal circulation pipe 22 are improved. By adjusting the diameter ratio, the amount of hot air absorbed by internal circulation pipe 22 and the amount of hot air discharged by upper exhaust pipe 21 are controlled, thus finely adjusting the outer and inner temperatures of the oven body. This design, through the cooperation of internal circulation pipe 22 and upper exhaust pipe 21, realizes heat reuse and emission control, reduces energy waste, and improves energy-saving and environmental protection performance. Precise temperature control helps improve the drying quality of metal sheets, ensuring that the sheets are not damaged due to excessive temperature, and also ensuring the uniformity of the drying process. Overall, this oven design, through the innovation of auxiliary structure 2, improves the temperature control capability of the oven, enhances thermal energy management efficiency, and provides a high-efficiency, energy-saving, and environmentally friendly drying solution for metal sheet production.

[0037] Working Principle: When using this metal sheet to manufacture the oven, the pre-prepared fuel is first ignited. The ignited flame enters the fuel nozzle 8 through the combustion aid pipe 3. The fuel nozzle 8 sprays flames to dry the surface of the sheet body 5 inside the oven. When it is necessary to extinguish the fuel nozzle 8, the user uses the pre-prepared fire tongs to move the flame arrestor 6 inside the air guard 4. The vertical groove 10 inside the air guard 4 and the rotating shafts on both sides of the flame arrestor 6 help the flame arrestor 6 rotate. At the same time, the positioning block 7 can prevent the user from excessively moving the fire tongs, causing the flame arrestor 6 to overturn. When the flame enters the flame arrestor 6, the flame gathering bucket 11 inside the flame arrestor 6 gathers the flame, and the flame gathering bucket 11 makes the flame contact the flame arrestor core 12. Since the flame arrestor core 12 is made of high density The flame is divided into countless small flames by the flame arrestor core 12. At the same time, the fire-collecting hopper 11 at the other end of the flame arrestor tube 6 can increase the contact area between the flame and the outside air, thereby extinguishing the flame sprayed from the fuel nozzle 8. Meanwhile, the air inlet 24 guides the hot air generated inside the oven body into the air storage plate 23. The filter 25 inside the air storage plate 23 filters the incoming gas. At the same time, the internal circulation pipe 22 retains some of the hot gas. Since the internal circulation pipe 22 is embedded inside the exterior of the oven body, the internal circulation pipe 22 can keep the exterior of the oven body at a certain temperature. Meanwhile, the upper exhaust pipe 21 discharges excess hot air to prevent the internal temperature of the oven body from becoming too high. This is the working principle of the oven used for the production of metal sheets.

Many modifications and variations will be apparent to those skilled in the art.
