Description

Technical Field

[0001] The invention relates to the field of packaging equipment, in particular to a glass bottle gas baking oven structure and a method for burning gas on a fire control plate. Background Art

[0002] At present, domestic glass glaze is screen-printed on glass bottles such as ampoules, injection bottles, and oral liquid bottles, and then baked and melted on the glass bottles to permanently retain the name, specifications, expiration date and other safety information of the medicine. Generally, electric ovens are used to bake and melt on glass bottles at high temperatures (700-1000℃). Due to the influence of factors such as electric energy thermal efficiency and heat conduction, if you want to maintain high temperature (700-1000℃) to bake glass bottles, you need a 3-5 meter long baking oven with a power consumption of 30-50 kilowatt / hour, the cost is 24 to 40 yuan / hour (average price 0.8 yuan / kilowatt). Since the 3 to 5 meter long furnace bakes the glass glaze onto the glass bottle in the 0.2 meter high temperature (700 to 1000℃) zone, its transmission components are more prone to failures at high temperatures, have poor reliability, and are difficult to control. In addition, the furnace of the electric oven is controlled by fixed temperature zones, and the overall heating and insulation of the furnace causes too much heat consumption in components that do not need to be heated (transmission components, furnace walls, etc.), resulting in waste. Summary of the invention

[0003] Aiming at the deficiencies of the prior art, the present invention proposes a glass bottle gas-fired baking oven structure and a method for burning gas on a fire control plate.

[0004] Among them, the specific technical scheme of the glass bottle gas baking oven structure is as follows:

[0005] The glass bottle gas baking oven is characterized by comprising a furnace base (1), a transmission component, a furnace insulation bottom plate (5), a furnace upper cover (6), a mixing burner (7) and a fire control plate (8);

[0006] The furnace heat-insulating bottom plate (5) and the mixing burner (7) are mounted on the furnace base (1);

[0007] A combustion chamber is formed between the furnace upper cover (6) and the furnace heat-insulating bottom plate (5);

[0008] The transmission component transports the glass bottle (11) into the combustion chamber;

[0009] The fire control plate (8) is installed on the inner side of the furnace upper cover (6), and the mixing burner (7) sprays fire to heat the fire sitting plate (8-1) of the fire control plate (8);

[0010] The fire control plate (8) comprises a fire sitting plate (8-1), a combustion plate (8-2), a connecting plate (8-3) and a fire baffle plate (8-4);

[0011] The fire baffle (8-4) and the fire control plate are arc-shaped structures;

[0012] The connecting plate (8-3) connects the fire baffle (8-4) and the combustion plate (8-2);

[0013] The combustion plate (8-2) is connected to the fire sitting plate (8-1).

[0014] It can be further configured as follows: the transmission component is arranged in the combustion chamber, the transmission component comprises an optical axis (2), a left-handed conveying shaft (3) and a right-handed conveying shaft (4), the right-handed conveying shaft (4) is located between the optical axis (2) and the left-handed conveying shaft (3), and the transmission ends of the optical axis (2), the left-handed conveying shaft (3) and the right-handed conveying shaft (4) are respectively connected to the transmission device through a transmission universal joint (10).

[0015] Furthermore, the furnace upper cover (6) comprises a top plate (6-1), a first side plate (6-2) and a second side plate (6-3), the upper end of the first side plate (6-2) is connected to the left side surface of the top plate (6-1), the lower end of the first side plate (6-2) is attached to the top of the furnace insulation bottom plate (5), and the upper end of the second side plate (6-3) is connected to the right side surface of the top plate (6-1);

[0016] An adjusting component (9) is provided on the furnace base (1), and an adjusting end of the adjusting component (9) acts on the second side plate (6-3) to adjust the furnace upper cover (6) up and down.

[0017] Furthermore, the curvature of the fire baffle (8-4) is R25, and the curvature of the combustion plate (8-2) is R60.

[0018] The specific technical scheme of the combustion method of gas on the fire control plate is:

[0019] The inner side of the fire seat plate is the fire seat surface, and the inner side of the fire baffle plate is the fire baffle surface, comprising the following steps:

[0020] S1: The fire-sitting plate is designed to be an inclined surface that deviates from the vertical direction by 10°±3°. The gas nozzle of the mixing burner sprays fire on the inner side of the fire-sitting plate so that the air-mixed gas adheres to the fire-sitting surface and burns without falling out of flame;

[0021] S2: The combustion surface guides the combustion to the fire-blocking surface to form an induced combustion layer for full combustion, so that the fire-blocking surface is heated to a temperature of 800℃~1000℃ for stable energy storage;

[0022] By adjusting the fire-blocking surface up and down and left and right, the upper surface of the glass bottle is heated at 700-1000°C to melt the glass glaze, thereby baking the text onto the glass bottle.

The air and fuel gas are fully mixed and burned efficiently as needed through the burner to achieve the effect of energy saving and environmental protection. The structure is simple and the operation and control are simple and reliable. As long as the 0.6-meter furnace is in the 0.1-meter high-temperature (700-1000°C) zone to bake the glass glaze onto the glass bottle, the natural gas burns 0.7 cubic meters / hour, the cost is 1.75 yuan / hour (average price 2.5 yuan / cubic meter), and the energy consumption cost is less than 7% of that of electricity.

[0024] Secondly, it has an efficient, energy-saving and environmentally friendly combustion method, and the combustion working surface and the heating temperature depth are adjustable, so that the heat energy can be fully applied to the glass bottle, and other working parts are only affected by the residual heat. The working conditions are stable, so the text on the baked glass glaze on the glass bottle is clear and uniform in color, and it avoids defects such as blurred text, diffusion, broken pen, and fallen text. The product quality is stable and reliable, and its production efficiency and economic benefits are immediate. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The furnace heat-insulating bottom plate 5 and the mixing burner 7 are installed on the furnace base 1;

[0036] The transmission component transports the glass bottle 11 into the combustion chamber. The specific structure of the transmission component is that the transmission component is arranged in the combustion chamber, and the transmission component includes an optical axis 2, a left-handed conveying shaft 3 and a right-handed conveying shaft 4. The right-handed conveying shaft 4 is located between the optical axis 2 and the left-handed conveying shaft 3. The transmission ends of the optical axis 2, the left-handed conveying shaft 3 and the right-handed conveying shaft 4 are respectively connected to the transmission device through a transmission universal joint 10.

[0037] The fire control plate 8 is installed on the inner side of the furnace upper cover 6, and the mixing burner 7 sprays fire to heat the fire sitting plate 8-1 of the fire control plate 8;

[0038] The fire control plate 8 includes a fire sitting plate 8-1, a combustion plate 8-2, a connecting plate 8-3 and a fire baffle 8-4;

[0039] The fire baffle 8-4 and the fire control plate are arc-shaped structures;

[0040] The connecting plate 8-3 connects the fire baffle plate 8-4 and the combustion plate 8-2;

[0041] The combustion plate 8-2 is connected to the fire plate 8-1. The area corresponding to the inner side of the combustion plate 8-2 is the combustion area, and the area corresponding to the inner side of the fire baffle is the combustion high temperature area. In this embodiment, the curvature of the fire baffle 8-4 is R25, and the curvature of the combustion plate 8-2 is R60.

[0042] The glass bottle gas baking oven used in the present invention is suitable for natural gas, liquefied gas, coal gas and other fuels. For different fuels, it is only necessary to replace the corresponding gas nozzle, and the air and the gas are fully mixed and burned efficiently as needed through the mixing burner. As long as the 0.6-meter-long furnace is in the 0.1-meter-long high-temperature (700-1000°C) zone to bake the glass glaze onto the glass bottle, the natural gas burns 0.7 cubic meters / hour, the cost is 1.75 yuan / hour (average price 2.5 yuan / cubic meter), and the glass bottle is automatically rotated in the furnace through the transmission device to be evenly heated. The furnace cover 6 is vertically and horizontally The position can be adjusted in all directions (up and down, left and right, front and back), so as to control the ignition point and the burning position so that the flame can burn the surface of the printed part on the glass bottle as needed without burning the transmission spiral shaft and other components. That is, only the surface of the printed part on the glass bottle is burned with a high-temperature flame, and the spiral shaft (transmission shaft) is suspended and automatically rotated on the glass bottle part to effectively complete the local high-temperature baking, and the other parts and parts that do not require temperature (including the unprinted part of the glass bottle) are not heated. The energy consumption cost is less than 7% of the electricity consumption. The transmission components have only two spiral shafts with few failures, good reliability and simple control.

[0043] The principle of the present invention is: the furnace heat preservation bottom plate is fixed on the furnace machine base, and the top of the furnace heat preservation bottom plate is an inclined surface inclined toward the fire rod, so as to facilitate cleaning of the furnace and reduce unnecessary furnace space to avoid unnecessary energy consumption;

[0044] Install the upper cover adjustment screws on the furnace base, place one side of the furnace upper cover on the furnace insulation bottom plate, and the other side on the upper cover adjustment screws. The furnace upper cover is designed to be composed of a heat control panel covered with a heat insulation cover;

[0045] Adjust the position of the furnace cover so that the inner side of the fire baffle is in appropriate position with the glass bottle up and down, left and right, front and back (the position of the upper cover adjustment screw can be fine-tuned up and down when it is working), so that the gas can attach to and burn on the inner side of the fire sitting plate, and then be guided and burned through the inner side of the combustion plate to the inner side of the fire baffle to form an induced combustion layer for full combustion, so that the upper surface of the glass bottle is heated at high temperature (700-1000℃) to melt the glass glaze, thereby baking the text onto the glass bottle.

[0046] Among them, the method of gas burning on the fire control plate, the inner side of the fire sitting plate is the fire sitting surface, the inner side of the fire baffle is the fire baffle surface, by adjusting the position of the furnace cover to control the fire surface and the glass bottle up and down, left and right, front and back to the required position, then take the following steps:

[0047] S1: For efficient combustion, the air will be fully mixed with the gas, which will cause flameout. Therefore, the fire-sitting plate is designed to be an inclined surface that deviates from the vertical direction by 10°±3°. The gas nozzle of the mixing burner sprays fire on the inner side of the fire-sitting plate so that the air-mixed gas will burn on the fire-sitting surface without flameout.

[0048] S2: The combustion surface guides the combustion to the fire-blocking surface to form an induced combustion layer for full combustion, allowing the fire-blocking surface to be heated to a high temperature of about 800°C to 1000°C for stable energy storage. The fire-blocking surface can be adjusted up and down and left and right to heat the upper surface of the glass bottle at 700 to 1000°C to melt the glass glaze and bake the text onto the glass bottle.
