Description
Technical field
The utility model is related to a kind of Casting Equipment, more particularly to a kind of molding sand cooling feed bin.
Background technology
Molding sand is used for the material of moulding in casting.Molding sand is general by Foundry sand, moulding sand binder and additional thing etc.
Modeling Material is mixed according to a certain percentage.Effect of the molding sand in Foundry Production is particularly important, because of the poor quality of molding sand
And the casting wasted product caused accounts for the 30~50% of the total waste product of casting.Meanwhile, after molding sand progress cast falls sand, type sand can be entered
Row is recycled, but the temperature of the molding sand reclaimed is higher, when being mixed with new molding sand, both can be influenceed mixed comprehensive
Can, therefore need to cool down the molding sand of recovery before the molding sand and new molding sand of recovery are mixed.
Existing molding sand cooling feed bin is primarily used to carry out cooling treatment to molding sand.As shown in figure 1, existing molding sand
Cooling feed bin mainly includes feed bin body and level is plugged in the cooling water pipe composition of hopper side wall, the feed bin body and set
There is storage cavity, the upper end of the feed bin body is provided with charging aperture, and the lower end of the feed bin body is provided with discharging opening, the cooling water
Pipe is extended through after storage cavity from the stretching of another side wall from the side wall of feed bin body.When needing that molding sand is cooled down
When, then only need to inject cooling water to one end of cooling water pipe, while the injection type sand into feed bin body, molding sand enters storage cavity
Contact reaching the purpose of cooling with cooling water pipe afterwards.
But in whole process, time of the cooling water in storage cavity in cooling water pipe is too short, contacted with the molding sand of heat
Time is also too short, so as to cause the utilization rate of the cooling water of unit volume relatively low.
Utility model content
The purpose of this utility model is to provide a kind of molding sand high to cooling water use efficiency and cools down feed bin.
To solve the above problems, the utility model provides a kind of molding sand cooling feed bin, including feed bin body, the feed bin sheet
The cooling tube of snakelike arrangement is provided with vivo, and the cooling tube includes the cooling straight tube and company through feed bin body front/rear end
The cooling U-tubes between adjacent two coolings straight tube are connected to, the feed bin body is arranged in parallel cold provided with least two
But manage, the neighbouring cooling tube is connected by U-shaped transition conduit, the feed bin body is additionally provided with for supporting cooling tube
Filter, the filter is provided with the filter bores passed through for molding sand.
By using above-mentioned technical proposal, the cooling tube of snakelike arrangement makes cooling water increase in the time of feed bin body, makes
Cooling water fully can take away the heat of molding sand in cooling tube.Meanwhile, cooling tube setting up and down, cold in feed bin body
But the cooling tube that water can be from below enters and from the cooling tube outflow from top, and this set makes the temperature of the cooling water of lower section
The temperature of the cooling water of top is will be less than, the temperature for meeting lower section molding sand in whole feed bin body is less than the temperature cloth of top molding sand
Put, the cooling water that cooling tube is flowed into from below touches the relatively low molding sand of temperature and it is cooled first, now cooling water
Temperature rises, when cooling water flows to top in cooling tube, and now the molding sand temperature of top is higher, and now temperature has built up
Cooling water molding sand is cooled again.Meanwhile, the setting of filter can not only slow down molding sand in the case where feed bin is intrinsic
Reduction of speed degree, make molding sand and cooling tube carry out it is sufficiently cold and hot exchange, while providing support force for cooling tube, prevent cooling tube quilt
Molding sand be collapsed.The setting of this structure, improves the utilization rate of cooling water, substantially reduces the temperature of molding sand.
As further improvement of the utility model, the upper surface of the filter is provided with supporting plate, the supporting plate upper surface
Provided with the groove placed for cooling tube.
By using above-mentioned technical proposal, the setting of supporting plate enables cooling branch pipe to be preferably placed on filter, together
When add contact area between cooling straight tube and filter, so as to increase filter to cool down the support that provides of straight tube
Power.
As further improvement of the utility model, the lower surface of the filter is provided with the reinforcement being connected with feed bin body
Muscle.
By using above-mentioned technical proposal, the setting of reinforcement strengthens filter and the connection of feed bin body madial wall is strong
Degree, so as to add the stability of a system of whole cooling feed bin.
As further improvement of the utility model, the cooling straight tube of the cooling tube of the neighbouring setting is not same
In one perpendicular.
By using above-mentioned technical proposal, above-mentioned setting can enable molding sand and cooling tube have bigger contact probability,
The time of contact of molding sand and cooling tube is increased simultaneously, so as to increase the cooling effect that whole molding sand cools down feed bin.
As further improvement of the utility model, the U-shaped transition conduit is equipped with built-in filtering with cooling tube junction
Net.
By using above-mentioned technical proposal, the setting of built-in screen pack can filter the impurity in cooling water, when needs pair
When impurity in cooling tube is cleared up, it is only necessary to disassemble U-shaped transition conduit, the impurity near screen pack is carried out clear
Impurity in reason, cleaning cooling tube becomes simple.
As further improvement of the utility model, the cooling tube includes at least six roots of sensation cooling straight tube.
By using above-mentioned technical proposal, the increase of cooling tube quantity can increase what cooling water flowed in feed bin body
Time, so as to improve the utilization rate of cooling water.
In summary, in feed bin body at least two layers snakelike arrangement cooling tube, while under a cooling side provided with use
To support the filter of cooling tube, so that add cooling water cools down feed bin utilization ratio in molding sand, while whole molding sand cooling
Feed bin is good to the cooling effect of molding sand.
