Description
Technical field
The utility model relates to a kind of parts of metal casting machine, and the heater assembly for providing the gas generator of sclerosis gas to use in a kind of cold-box manufacture is provided.
Background technology
The advantages such as cold box process adopts is the technique to ventilation sclerosis core in core box, and firm time is short, production efficiency is high owing to having, do not need heating, knockout performance is good are widely used in core manufacture.Its operation principle is, by core shooter, core sand is blown into core box, then by gas generator, liquid sclerotherapy is flashed to gaseous state and be blown into core box, by chemical reaction or catalytic reaction between gaseous state curing agent and core sand resin, make core sand in core box harden into rapidly the core of required form and dimensional accuracy.In cold box process, conventional curing agent has triethylamine, methyl formate etc., is liquid under normal temperature, need to pass through heating and gasifying, with certain pressure, is blown into core box, just can meet technological requirement.
In prior art, conventionally adopt compressed air to heat and carry sclerosis gas.It is example that the sclerosis gas of take adopts triethylamine, in gas generator, first compressed air be heated to 85～95 ℃ by heater, enter in blender, liquid triethylamine is transported to blender by constant displacement pump simultaneously, under the pressure of constant displacement pump and the effect of mixer nozzle, be atomized into droplet, compressed air after heating fully mixes with the vaporific drop of triethylamine, and triethylamine is vaporized, and forms mist and exports and be blown into core box.Wherein, the heater of gas generator is mainly by heating tube, the heat medium of aluminium matter, the composition such as breather pipe and thermocouple, heater housing adopts the slender type tubular construction of cylinder, heating tube adopts v-shaped structure to be evenly distributed in tubular construction, breather pipe also intersects and is uniformly distributed with heating tube with v-shaped structure simultaneously, in cylindrical shell, between heating tube and breather pipe, pouring into aluminium liquid is connected, and carry out heat transmission with this, tubular calandria is provided with air inlet and gas outlet, be connected with two end interfaces of V-arrangement breather pipe respectively, compressed air enters from the import of heater, after the heating of V-arrangement pipe, from gas outlet, flow out, enter main frame blowning installation.Said structure exists heat-transfer effect poor, the slow and lower problem of continuous capability of hot-air temperature rise, design temperature and outlet temperature are poor larger, even can arrive more than 50 ℃, affect the normal gasification of triethylamine, and then affected the production efficiency of curing efficiency and the main frame of core.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of gas generator heater assembly, pass through architecture advances, under the constant prerequisite of heating power, promote heater the efficiency of heating surface, continue the stability of heat-transfer capability and heating-up temperature, to reduce the hardening time of blowing.
To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of gas generator heater assembly, mainly by heating tank body, be arranged on a plurality of breather pipes and a plurality of heating tube in heating tank body, air inlet and the gas outlet being arranged on heating tank body forms, same one end at heating tank body is provided with inlet plenum and the discharge chamber of being separated by separate cavities, described air inlet is communicated with described inlet plenum, and described gas outlet is communicated with described discharge chamber; Described breather pipe is W shape, and the two ends of each breather pipe are communicated with respectively described inlet plenum and discharge chamber; Described heating tube is W shape, forms heat conduction be connected between heating tube and breather pipe through aluminium.
In technique scheme, between heating tube and breather pipe, through aluminium formation, leading hot linked method is prior art, can, after arranging breather pipe and heating tube, to heating tank perfusion in vivo aluminium liquid, treat that aluminium liquid solidifies.By aluminium, conduct heat, the breather pipe of W shape is heated by the heating tube of W shape, and the compressed air of normal temperature is in W shape breather pipe in flow process, after breather pipe homogeneous heating, from the outlet of heater, flow out, effectively solved in prior art continuous heating ability low, add the problem of poor heat stability.
Preferred technical scheme, described heating tube and breather pipe vertical spacing are arranged.
Further technical scheme, is provided with thermocouple in described heating tank body.Heating-up temperature is detected by thermocouple and feeds back, and is connected with temperature controller, and the temperature of control heater can also realize with electric control system onlinely, at the enterprising Mobile state of operation interface, shows.
In technique scheme, the external muff that is provided with of described heating tank.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model is arranged to W shape structure by heating tube and breather pipe, air heat area and heat transfer capacity have increased respectively more than 30% and 100%, make to heat Air Temperature lifting speed and provide hot-air continuous capability to be enhanced, the difference of design temperature and outlet temperature is controlled in 10 ℃.
