Abstract
The utility model provides a cooling box for a sand temperature regulator, which is simple in structure, high in cooling efficiency and capable of realizing uniform cooling and cooling all sand to a specified temperature with cooling effect. The cooling box comprises a shell, and is characterized in that a sand inlet and a sand outlet are formed in the top and the bottom of the shell respectively; a plurality of cooling water tubes are transversally arranged in the shell; the cooling water tubes are arranged in a plurality of rows in a staggered manner; gaps among the cooling water tubes form a flowing space for sand; and the both ends stretching out of the shell, of each cooling water tube are connected with another cooling water tube by corrugated tubes respectively.
Description
Technical field
The utility model relates to the sand preparing machine of casting industry, is specially the cooler bin of sand temperature modulator.
Background technology
Precoated sand, sand grain surface is covered with molding sand or the core of one deck hard resin film before moulding, precoated sand moulding is used in the intricate casting that dimension precision requirement is higher, one of optimum shaping materials such as automobile, tractor, hydraulic part, along with the development of domestic and international machinery industry especially automobile industry, more and more higher to casting quality requirement, the application of precoated sand is more and more extensive.Along with scientific and technological high speed development, supermatic foundry production line is used in a large number, and this is the major measure that casting in enormous quantities is boosted productivity.But the thing followed is that molding sand cycle period is short, sand temperature rise, thereby the performance to molding sand, the production order, casting quality all can have a great impact, and cause so-called hot sand problem.Mo(u)lding line automaticity is higher, and the circulation of sand is faster, and hot sand problem is by even more serious.Therefore, on foundry production line, must control effectively to the temperature of sand, guarantee casting quality.
On existing precoated sand production line, conventionally can adopt and carry out boiling cooling bed and to molding sand, carry out cooling as sand temperature modulator; but can not guaranteeing the temperature of all cooled sands, the mode of shaking out of boiling cooling bed meets the requirements; cooling velocity is slow; fail evenly cooling all sands; to such an extent as to most parts of sand is uncolled during to predetermined temperature; existing part sand temperature is too low, and the too low meeting of sand temperature causes sand setting rate slow, has affected the type time.
Utility model content
For the problems referred to above, the utility model provides the cooler bin of sand temperature modulator, and it is simple in structure, and cooling effectiveness is good, can realize evenly cooling, by all sands be cooled to regulation temperature, good cooling results.
Its technical scheme is such: it comprises housing, it is characterized in that: the top of described housing and bottom are set to respectively sand inlet and sand export, in described housing, transverse row is furnished with some cooling water pipes, described cooling water pipe many misarrangement rows arrange, gap between described cooling water pipe forms the flowing space of sand, and the two ends that described cooling water pipe stretches out housing connect another cooling water pipe by corrugated tube respectively.
It is further characterized in that: the top of described housing is connected respectively cooling water inlet and coolant outlet with the cooling water pipe of bottom;
The outer wall of described cooling water pipe is provided with fin;
On the outer wall of described housing, arrange and inspect door, described in inspect on the outer wall of door cover plate handle be set;
Described cooling water inlet, coolant outlet place are respectively arranged with collector pipe.
The beneficial effects of the utility model are: enclosure interior is provided with multilayer cooling pipe, adopt reverse-flow heat exchange form, cooling water flows from lower to upper in pipeline, sand relies on gravity slow decreasing in the gap of cooling pipe, by tube wall, carry out heat exchange with circulating water, finally reach the object that sand temperature regulates, the wrong row of cooling water pipe makes sand in the descending process of complications, constantly change position, guarantee that sand fully dispels the heat, realize evenly cooling, all sands are cooled to the temperature of regulation, good cooling results, the outer wall of cooling water pipe is provided with fin, increased heat exchange exchange area large, further improve cooling effect.
Accompanying drawing explanation
Fig. 1 is that master of the present utility model looks schematic diagram;
Fig. 2 is schematic side view of the present utility model;
Fig. 3 is the profile of cooling water pipe of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
See Fig. 1, Fig. 2, Fig. 3, the utility model comprises housing 1, the top of housing 1 and bottom are set to respectively sand inlet 2 and sand export 3, the interior transverse row of housing 1 is furnished with many row's cooling water pipes 4, the outer wall of cooling water pipe is provided with fin 11, cooling water pipe 4 wrong row arrange, gap between cooling water pipe 4 forms the flowing space of sand, the two ends that cooling water pipe 4 stretches out housing 1 connect another cooling water pipe 4 by corrugated tube 5 respectively, be arranged on the top of housing 1 and the cooling water pipe of bottom and be connected respectively cooling water inlet 6 and coolant outlet 7, cooling water inlet 6 and coolant outlet 7 places are respectively arranged with collector pipe 8, on the outer wall of housing 1, arrange and inspect door 9, inspect on door 9 outer wall cover plate handle 10 is set.
Housing 1 inside is provided with multilayer cooling pipe 4, adopt reverse-flow heat exchange form, cooling water inlet 6 is arranged on below, coolant outlet 7 is arranged on the top, cooling water flows from lower to upper in pipeline, sand relies on gravity slow decreasing in the gap of cooling pipe 4, by tube wall, carry out heat exchange with circulating water, finally reach the object that sand temperature regulates, the wrong row of cooling water pipe 4 makes sand in the descending process of complications, constantly change position, guarantee that sand fully dispels the heat, the outer wall of cooling water pipe is provided with fin, increased heat exchange exchange area large, good cooling results, inspect arranging of door 9 and facilitate plant maintenance, maintenance and the movement of equipment is convenient in the setting of cover plate handle 10.
