Abstract
The utility model provides a cooling air amount adjustment device for a precoated sand mixer. The cooling air amount adjustment device is simple in structure, reasonable in design and capable of ensuring uniform air distribution in a small area and adequate heat exchange between cold air and sand due to cooling air amount adjustment, and accurately controlling the air amount used in the cooling area, as well as good cooling effect. The cooling air amount adjustment device comprises a ventilation tube, wherein a rotary shaft is arranged in the ventilation tube; a valve plate is fixedly connected to the rotary shaft in the ventilation tube; an adjustment plate and a control rod are sequentially arranged at one end (stretching out of the ventilation tube) of the rotary shaft; the adjustment plate is sleeved on the rotary shaft; the adjustment plate is fixedly connected with the outer wall of the ventilation tube; one end of the control rod is fixedly connected with the rotary shaft, and a through hole is formed in the other end of the control rod; a plurality of corresponding adjustment holes are formed in the adjustment plate; and a bolt penetrates through the through hole and then is located by any one adjustment hole.
Description
Technical field
The utility model relates to precoated sand production equipment technical field, is specially the cooling air quantity adjusting device of coated sand mixer.
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, development along with 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.
Puddle mixer is a kind of visual plant during precoated sand is produced, and by sand, moulding sand binder and auxiliary material are mixed, binding agent and auxiliary material is uniformly distributed and is effectively coated on sand grain surface.Temperature during mulling can all can have a great impact the performance of molding sand, the production order, end product quality, therefore, when mulling, must control effectively to the temperature of sand, and the quality of guarantee finished sand.Can adopt the air-cooled cooling temperature control of realizing, but in running, there is certain problem, as: cooling air quantity is bigger than normal, allocation of the amount of air is inhomogeneous, SR is large, power consumption is large, systematic running cost is with high, it is not equipped with the cooling air that can regulate pointedly, make its air-distribution in less region even, between cold wind and sand material, carry out fully heat exchange, accurately control the air quantity of using of cooled region.
Utility model content
For the problems referred to above, the utility model provides the cooling air quantity adjusting device of coated sand mixer, it is simple in structure, reasonable in design, the cooling air quantity that can regulate, makes its air-distribution in less region even, carries out fully heat exchange between cold wind and sand material, accurately control the use air quantity of cooled region, good cooling results.
Its technical scheme is such: comprise ventilation duct, it is characterized in that: in described ventilation duct, be provided with rotating shaft, in ventilation duct, in described rotating shaft, be fixedly connected with valve plate, one end that described ventilation duct is stretched out in rotating shaft is provided with adjustable plate, control lever successively, described adjustable plate is sleeved in described rotating shaft, described adjustable plate is fixedly connected with the outer wall of ventilation duct, one end of control lever is fixedly connected with described rotating shaft, the other end of control lever is provided with through hole, described adjustable plate is provided with the adjusting hole of some correspondences, and bolt is through described through hole and adjusting hole location described in any one.
It is further characterized in that: described control lever is perpendicular to the plane of valve plate;
Described adjustable plate comprises right angle fan-shaped panel, on right angle fan-shaped panel, along fan-shaped circular arc, is evenly arranged at intervals with five adjusting holes.
The beneficial effects of the utility model are: by the position of lever for adjusting oil, make the through hole of control lever corresponding from different adjusting holes, inserting bolt is fixed the angle of inclination that can regulate the valve plate in ventilation duct again, thereby regulate the air port size of ventilation duct, and then regulate the cooling air quantity through ventilation duct, and make its air-distribution in less region even, between cold wind and sand material, carry out fully heat exchange, the air quantity of using of accurately controlling cooled region, improves cooling effect.
