Description
Technical field
The utility model is related to Casting Equipment field, specially a kind of high temperature modification Sand Cooling System.
Background technology
In casting process, after casting pouring, casting in casting mold cooling procedure can most heat transfer to molding sand,
Sand temperature is caused to increase, which will be used as return sand, and warming phenomenon is in placer iron than small, production thick-walled casting, mo(u)lding line
It is particularly acute in the case that productivity is high, molding sand turnover is fast.
The return sand of heat, which has to pass through, to cool, so that into the return sand temperature in sand mixer at 49 DEG C hereinafter, working as
When molding sand temperature is higher than 49 DEG C, compact rate of molding, gas permeability, green compression strength, dry compression and sand mold air-dried strength can all reduce.
In traditional technology, generally using the principle of humidification cooling, i.e., water is uniformly sprayed into hot sand, made by cooling down equipment
Moisture is sufficiently stirred with hot sand, the type of cooling cause the moisture in molding sand it is higher, influence further use, and cooling effect
Generally.
Utility model content
The purpose of this utility model is to provide a kind of high temperature modification Sand Cooling System, can realize the efficient cooling of molding sand, and
Ensure humidity in the range of normal value.
Realizing the technical solution of above-mentioned purpose is：High temperature modification Sand Cooling System, it is characterised in that：Including from left to right successively
The feeding conveyor of setting air-dries cooling device and outfeed belt conveyor；
The air-dried cooling device includes housing, and the lower end of housing is used as conglomeration damp sand discharge port for opening, housing
Top is feed inlet, and the middle part side of housing is provided with drying air fan, and being provided with dry sand on the housing of drying air fan opposite side goes out
Sand mouth；
The port of export of the feeding conveyor is corresponding with the feed inlet of housing tip, is evenly equipped with above feeding conveyor
The more atomizing nozzles installed by stent, are evenly equipped with atomizer on atomizing nozzle；
The feed end of the outfeed belt conveyor is provided with feed hopper, and the input end of feed hopper, which is less than, air-dries the dry of cooling device
Sand sand export, the dry sand sand export of the air-dried cooling device connect the input end of feed hopper by pipeline.
Further, it air-dries feed inlet of the drying air fan of cooling device apart from the top of housing and is not less than 2 meters.
Further, it air-dries between the conglomeration damp sand discharge port of cooling device and the feed inlet on top and is connected with helical feed
Conglomeration damp sand is delivered to the feed inlet of air-dried cooling device by screw conveyor by machine.
The damp sand of the utility model carries out water cooling atomization by the atomizer of feeding conveyor first, enters back into air-dried cold
But device by under placement in height, further air-dries cooling, and middle part by drying air fan to molding sand again dry cooling after,
Drying type sand is blown into the feed hopper for being blown into outfeed belt conveyor, completes discharging conveying.
And conglomeration damp sand is under the effect of gravity, into screw conveyor, is again introduced into air-dried cooling device into traveling one
Step ground is dry, cooling.
The utility model is simple in structure, usable highly effective, the purpose of qualified ground finishing type sand cooling but.
Description of the drawings
Fig. 1 is the structure principle chart of the utility model.
Specific embodiment
As shown in Figure 1, the utility model includes the feeding conveyor 1 set gradually from left to right, air-dries 2 and of cooling device
Outfeed belt conveyor 3.
Air-dry cooling device 2 includes housing 2.1, and the lower end of housing 2.1 is used as conglomeration damp sand discharge port 2.2 for opening,
The top of housing 2.1 is feed inlet 2.3, and the middle part side of housing 2.3 is provided with drying air fan 2.4,2.4 opposite side of drying air fan
Housing 2.1 on be provided with dry sand sand export 2.5.
The port of export of feeding conveyor 1 is corresponding with the feed inlet 2.3 on 2.1 top of housing, and the top of feeding conveyor 1 is equal
The more atomizing nozzles 1.2 installed by stent 1.1 are furnished with, atomizer 1.3 is evenly equipped on atomizing nozzle 1.2.
The feed end of outfeed belt conveyor 3 is provided with feed hopper 3.1, and the input end of feed hopper 3.1, which is less than, air-dries cooling device 2
Dry sand sand export 2.5, air-dry cooling device 2 dry sand sand export 2.5 pass through pipeline 4 connect feed hopper 3.1 input end.
It air-dries and is connected with screw conveyor between the conglomeration damp sand discharge port 2.2 of cooling device 2 and the feed inlet 2.3 on top
5, the feed inlet connection of screw conveyor 5 air-dries the conglomeration damp sand discharge port 2.2 of cooling device 2, discharge port connection air-dries cooling
The feed inlet 2.3 of device 2.
Feed inlet 2.3 of the drying air fan 2.4 of cooling device 2 apart from the top of housing 2.1 is air-dried not less than 2 meters, makes type
Sand forms the difference in height to fall, and further molding sand is dried, is cooled down.
The damp sand of the utility model carries out water cooling atomization by the atomizer 1.3 of feeding conveyor 1 first, enters back into wind
Dry cooling device 2, by under placement in height, further air-drying cooling, and dried again to molding sand by drying air fan 2.4 at middle part
After cooling, drying type sand is blown into the feed hopper 3.1 for being blown into outfeed belt conveyor 3, completes discharging conveying.
And conglomeration damp sand is under the effect of gravity, into screw conveyor 5, is again introduced into air-dried cooling device 2 into traveling
One step it is dry, cooling.
