Abstract
The utility model relates to a carbon dioxide gas quick heater device which is characterized in that the quick heater device is provided with a water tank (7); water (4) is filled in the water tank (7); a gas sealing box (3) is arranged in the water tank (7); two sides of the gas sealing box (3) are connected with a gas inlet belt (8) and a gas outlet belt (9) through a sealing gasket (5) and a connecting sleeve (6); the bottom of the water tank (7) is arranged on a heating source (1) through a support (2); the water tank (7) is circular or square; and the gas sealing box (3) is made of seamless metal spiral tubes with the thickness of 3-5mm. The utility model can be widely applied to production in winter of the foundry industry. The utility model has simple manufacturing, low manufacturing cost and convenient and safe use, therefore, the utility model has wide practical application value in the whole foundry industry, particularly the production in winter of the small and medium-sized foundry industry.
Description
Technical field
The utility model discloses a kind of carbon dioxide nonstorage calorifier, belong to the Casting Equipment technical field.
Background technology
In foundry production, the sclerosis of sodium silicate sand mainly forms a kind of collastromin with certain degree of hardness by the waterglass generation chemical reaction in carbon dioxide and the molding sand and realizes, and under the carbon dioxide environment that temperature is lower in the winter time, especially when temperature reaches below-5 ℃, the used in amounts that causes dry same molding sand carbon dioxide is usual 3-10 times, this not only wastes carbon dioxide in a large number, improve production cost, extend labour time, reduce labor productivity, also have a strong impact on the uniformity of casting mold hardenability, and then cause casting defect easily.What sell on the domestic and international market at present is the electrical heating type device; this device is protective medium with water; heat by power supply; be provided with the special gas closed cavity; need the special-purpose power circuit that connects of adapted; inconvenience moves whenever and wherever possible and uses; heating back gas temperature changes not obvious; cost an arm and a leg (the carbon dioxide gas body heater price of the logical single hole of a Daepori is about 7500 yuan), this device has in use increased the caused unsafe factor of power supply, owing to used electrical installation; in use damage easily; in case component wear, inconvenient maintenance and maintenance cost are higher, so this device is not suitable for the production of medium-sized and small enterprises.
Summary of the invention
At the problems referred to above and defective, task of the present utility model provides a kind of more safe and reliable, the nonstorage calorifier of carbon dioxide efficiently easy to make.Pass through research and analysis, decision utilizes water to be the carbon dioxide security medium that is heated, utilize the warming fire to be heating source (but various thermals source such as firewood fire, coal fire or coke fire), utilize the helical form seamless metal pipe to be the air seal case, special-purpose sealing gasket and adapter sleeve are as the jockey of seal box and gas conveyer belt.The concrete solution of carbon dioxide nonstorage calorifier is as follows: a water tank is set, fills water in the water tank, and the built-in air seal case of water tank, the both sides of air seal case tap into the band of gas and go out the band of gas by sealing gasket and adapter sleeve.Water tank is arranged on the heating source below by support.The shape of water tank is generally circular or square, and volume is as the criterion to satisfy to use.Require water tank to be convenient to move, place steadily, in heating process, should not deform and drainage occurs.It is that the seamless metal helix tube of 3-5mm is made that the air seal case is selected thickness for use.Heating source utilizes the warming stove fire can satisfy heat demand, need not to increase extra means.
Method described in the utility model and device can be widely used in casting industry and produce winter, because the utility model preparation method is simple, cost of manufacture is low modest, safe and convenient to use, so, have actual application value widely in the production practices in especially middle-size and small-size foundry industry winter at whole casting industry.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1, heating source, 2, support, 3, the air seal case, 4, water, 5, sealing gasket, 6, adapter sleeve, 7, water tank, 8, the air inlet band, 9, go out the band of gas.
The specific embodiment
Embodiment of the present utility model is referring to accompanying drawing: this carbon dioxide nonstorage calorifier is that a water tank 7 is set, fill water 4 in the water tank 7, water tank 7 built-in air seal casees 3, the both sides of air seal case 3 tap into the band of gas 8 and go out the band of gas 9 by sealing gasket 5 and adapter sleeve 6.Water tank 7 is arranged on the heating source 1 below by support 2.The shape of water tank 7 is generally circular or square, and volume is as the criterion to satisfy to use.Require water tank to be convenient to move, place steadily, in heating process, should not deform and drainage occurs.It is that the seamless metal helix tube of 3-5mm is made that air seal case 3 is selected thickness for use.Heating source 1 utilizes the warming stove fire can satisfy heat demand, need not to increase extra means.
The whole application machine parts of this carbon dioxide fast unit connect, utilize in advance in use sealing gasket 5 and adapter sleeve 6 with air seal case 3 with air inlet band 8 with go out the band of gas 9 and connect respectively, the parts that connect are put into the water tank 7 of suitable quantity of water 4 media of packing into, again water tank 7 is placed on the support 2 of heating source 1, carbon dioxide can be transported to through air inlet band 8 from gas cylinder after everything work is carried out and carry out gas heating in the gas air seal case 3, when gas with normal flow by air seal case 3 after going out the band of gas 9 output, directly enter sand mold and carry out the casting mold sclerosis, the carbon dioxide temperature of this moment has reached more than 20 ℃, detects maximum heating temperature through the scene and can reach 40 ℃.Because actual production is high-temperature too, so control the carbon dioxide temperature between 20 ℃-25 ℃, to satisfy the production demand by the physical dimension of regulating parts air seal case 3 and support 2.
