Abstract
The utility model discloses a kind of sand grains cooling devices, including roller, in the top of the roller be equipped with spray equipment, the roller includes cylinder and bung, the bung is connect by bearing with the cylinder, it is respectively equipped with bleeding point and sand inlet on the bung, the bleeding point is connected with vacuum pump by tracheae, after sand grains enters cylinder, bung vacuum pump takes the hot-air in cylinder away, thus can tentatively it be cooled down to the sand grains in cylinder, reduce the temperature of inner barrel, then cylinder is in rotation process, spray equipment will be on cold water sprays to roller, cooling processing is carried out to hot sand, in the hot water deposit cooling bay of generation, hot water in cooling bay carries out cooling processing under the action of negative-pressure cup, to improve the cooling effect of negative-pressure cup.
Description
Technical field
The utility model is related to a kind of Sand Cooling System, especially a kind of sand grains cooling device.
Background technology
When being cast using V methods, a large amount of hot sand is will produce, in order to allow the utilization rate for improving sandstone, therefore in casting,
It needs quickly to cool down hot sand, natural cooling is influenced by many natural conditions factors, and cooling effect is poor, cooling effect
Fruit unobvious are easy to influence the use of next time.
Utility model content
The technical assignment of the utility model is to be directed to the above the deficiencies in the prior art, and provide a kind of sand grains cooling device.
Technical solution adopted by the utility model to solve its technical problems is：A kind of sand grains cooling device, including roller,
It wherein is equipped with spray equipment in the top of the roller, the roller includes cylinder and bung, and the bung passes through bearing and institute
Cylinder connection is stated, bleeding point and sand inlet are respectively equipped on the bung, the bleeding point is connected with vacuum pump by tracheae.
It is further improved：The sand inlet is located above the bleeding point, and filter sand net is equipped in the bleeding point.
It is further improved：The length that the sand inlet extends into cylinder extends more than the bleeding point into cylinder
Length.
It is further improved：It is equipped with sink in the lower section of the roller, the bottom of the sink is connected in turn by water pipe
Cooling bay, cistern, the cistern are connect with the spray equipment.
It is further improved：Negative-pressure cup is equipped in the cooling bay, the negative-pressure cup is connect with the vacuum pump.
The advantages of the utility model：Firstly because being equipped with bleeding point, after sand grains enters cylinder, bung vacuum on bung
Pump takes the hot-air in cylinder away, thus can tentatively be cooled down to the sand grains in cylinder, reduce the temperature of inner barrel
Degree, then cylinder is in rotation process, and spray equipment carries out cooling processing by cold water sprays to roller to hot sand, generation
Hot water is stored in cooling bay, and the hot water in cooling bay carries out cooling processing under the action of negative-pressure cup, to improve negative-pressure cup
Cooling effect.
Description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is the structural schematic diagram of the utility model roller.
Specific implementation mode
The utility model is described below with reference to the accompanying drawings of the specification.
As shown, a kind of sand grains cooling device, including roller 1, wherein being equipped with spray equipment in the top of the roller 1
7, the roller 1 includes cylinder 11 and bung 14, and the bung 14 is connect by bearing 12 with the cylinder 11, in the bung
Bleeding point 15 and sand inlet 13 are respectively equipped on 14, the bleeding point 15 is connected with vacuum pump 3 by tracheae；The sand inlet 13
Above the bleeding point 15, filter sand net 16 is equipped in the bleeding point 15；The sand inlet 13 extends into cylinder 11
Length, the length extended into cylinder 11 more than the bleeding point 15；
Be equipped with sink 2 in the lower section of the roller 1, the bottom of the sink 2 by water pipe be connected in turn cooling bay 4,
Cistern 6, the cistern 6 are connect with the spray equipment 7；Negative-pressure cup 5, the negative-pressure cup 5 are equipped in the cooling bay 4
It is connect with the vacuum pump 3.
Its operation principle：When work, hot sand is sent into cylinder 11 by conveying device first, then in cistern 7
Cold water is sprayed at by spray equipment 8 on roller 1, and the hot sand in roller 1 is transported to roller 1 by roller 1 in rotation process
The other end, in the process cold water cooling processing is carried out to the outer wall of cylinder 11, the hot water of generation is fallen into sink 2, water pump will
Water in sink 2 is pumped into cooling bay 4, then that the water cool down feeding cistern 7 is interior, from realizing following for cooling water
Ring uses, and additionally, due to being additionally provided with bleeding point 15 on bung 14, therefore negative pressure state is substantially in cylinder 11, and sand grains enters
The hot gas generated after cylinder 11 is quickly taken away, and the efficiency of sand grains cooling is improved, the filter sand net being arranged at bleeding point 15
16 can prevent sand grains from being taken away by vacuum pump, sand inlet 13 is arranged above bleeding point 15, the benefit being arranged in this way is sand grains
In dropping process, sand grains can pass through from bleeding point 15, the heat that sand grains all at this time is carried all in dispersity, sand grains
Gas can be quickly pumped.
The above description is only the embodiments of the present invention, every to be made using the utility model specification and accompanying drawing content
Equivalent structure or equivalent flow shift, be applied directly or indirectly in other relevant technical fields, and be similarly included in this
In the scope of patent protection of utility model.
