Description
Technical field
The invention discloses a kind of spiral cooling device, relate to casting, field of powder metallurgy, be particularly useful for the cooling processing of particle, powder.
Background technology
Foundry goods is widely used in various plant equipment, and foundry goods is the product produced by casting technique.Casting the most widely technique is other sand that use quartz sand moulding or other refractoriness are higher, and for economizing on resources, country specifies old sand utilization rate, and one of casting technique that old sand utilization rate is the highest is lost foam casting, the casting of V method.All molding sand assistance modeling will be used in these two kinds of casting techniques.A large amount of heats drawn by molding sand in modeling process from foundry goods, must reduce its temperature, just can recycle.
The molding sand cooling device being widely used in now casting production process is boiling cooling bed.The operation principle of boiling cooling bed is risen by sand blast with high-power blower, and form fluidized state, molding sand drops on water cooling tube, water absorbs heat, heat is taken away a part by recirculated water, then by exhausting mode, the heat of boiling sand is taken away a part, to reach the object reducing molding sand temperature.The shortcoming adopting boiling cooling bed is that power of fan is large; water cooling tube maintenance, replacing difficulty; equipment manufacturing cost is high; fault rate is high, usually shuts down completely because boiling cooling bed fault causes, reduces productivity ratio; add production cost; air blast is simultaneously blown sand and is caused dust content in local air high, and harm operator's is healthy, causes occupational disease occurred frequently.
In order to overcome above-mentioned difficulties, Chinese patent CN204486703U discloses a kind of cooling device, comprise: housing, the upper end of housing is connected with the exhaust column for exhausting, position near exhaust column on the sidewall of housing is connected with into sand chute, position on the sidewall of housing bottom it is connected with the chute that shakes out, and is entering sand chute and the position that shakes out between chute is provided with the multistage cooling device for cooling casting molding sand from top to bottom successively in housing.Sand in dropping process through one-level cooling device and secondary cooling device water cooling, and through exhaust column suction formed wind carry out air cooling, achieve cooling and purification object.But the step that this technology adopts air blast to blow sand equally, causes dust pollution, harm operator's is healthy, in addition molding sand and cooling tube time of contact is short, contact area is insufficient, there is the shortcoming that cooling effectiveness is low.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of environmental protection, cooling device that cooling effectiveness is higher.
In order to solve the problems of the technologies described above, base case provided by the invention is:
A kind of spiral cooling device, comprises charging aperture, spirality sleeve pipe, discharging opening, water inlet pipe, outlet pipe, water pump; Spirality sleeve pipe is divided into inner and outer tubes, and interior pipe external diameter is less than outer tube diameter, and be lumen between inner and outer tubes, lumen lower ending opening is connected with water inlet pipe, and lumen upper end is connected with delivery port; Interior pipe upper end connects charging aperture, and lower end connects discharging opening.
First be full of water with water pump by lumen during use, material then to be lowered the temperature is entered in spiral by charging aperture and manages, and material transfers heat to the flowing water in lumen in the process slided along pipe in spiral, thus reduces temperature.
In this scheme, material passes through in interior pipe, avoids exposing in atmosphere, reduces the pollution to air; With material between cooling tube compared with landing, material glides along pipeline, increases the contact area of material and cooling pipe; Helical design adds material and flowing water time of contact.In sum, this invents not only environmental protection, and improves cooling effectiveness.
Prioritization scheme one: as the optimization to base case, outlet pipe connects condensing unit, and condensing unit connects water inlet pipe.Establish water circulation system like this, water at low temperature enters the lumen of spirality sleeve pipe from water inlet pipe, in lumen, realize heat exchange, flow out high-temperature water at delivery port, high-temperature water enters condensing unit, through condensation process, become water at low temperature, then enter spirality sleeve pipe lumen by water inlet pipe, so circulate.This scheme realizes recycling of water, economize energy.
Prioritization scheme two: as another optimization to base case, outlet pipe and water inlet pipe are equipped with water pipe head.Water pipe head is arranged on outlet pipe and water inlet pipe place respectively, and water pipe head can connect heating installation.The high-temperature water flowed out from outlet pipe like this carries out heat exchange with cold air inside heating installation, becomes water at low temperature, then enters spirality sleeve pipe lumen by water inlet pipe, so circulate.This scheme by the heat in molding sand by Water transport to room air, for daily heating.Achieve effective utilization of energy like this, energy-conserving and environment-protective.
Prioritization scheme three: as the optimization to prioritization scheme two, water pipe head is Y shape.Y shape water pipe head respectively with go out/water inlet pipe, condensing unit, heating installation be connected; Be provided with valve between the Y shape water pipe head of condensing unit and outlet pipe, between the Y shape water pipe head of condensing unit and water inlet pipe, be provided with valve; Be provided with valve between the Y shape water pipe head of heating installation and outlet pipe, between the Y shape water pipe head of heating installation and water inlet pipe, be provided with valve.Like this when needs heating, open the valve that heating installation both sides connect, close the valve that condensing unit both sides connect, be prioritization scheme two; In time not needing heating, open the valve that condensing unit both sides connect, close the valve that heating installation both sides connect, be prioritization scheme one.
