Abstract
The invention 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 present invention relates to precoated sand production equipment technical field, be specially a kind of cooling air quantity adjusting device of coated sand mixer.
Background technology
Precoated sand, namely 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 higher intricate casting of dimension precision requirement, one of optimum shaping materials such as automobile, tractor, hydraulic part, along with the development of domestic and international machinery industry especially automobile industry, require more and more higher to casting quality, 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 being mixed, makes binding agent and auxiliary material be uniformly distributed and effectively be coated on sand grain surface.Temperature during mulling all can be able to have a great impact the performance of molding sand, the production order, end product quality, therefore, must control effectively when mulling to the temperature of sand, the quality of guarantee finished sand.Air-cooled realization can be adopted to cool temperature control, but in running, there is certain problem, as: cooling air quantity is bigger than normal, allocation of the amount of air is uneven, SR is comparatively large, power consumption is large, system cloud gray model expense is 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 heat exchange fully, accurate controlled cooling model region use air quantity.
Summary of the invention
For the problems referred to above, the invention provides a kind of cooling air quantity adjusting device of coated sand mixer, its structure is simple, reasonable in design, the cooling air quantity that can regulate, makes its air-distribution in less region even, carries out heat exchange fully between cold wind and sand material, the use air quantity in accurate controlled cooling model 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, valve plate is fixedly connected with in ventilation duct, in described rotating shaft, 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 adjusting hole location described in described through hole and 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, and right angle fan-shaped panel is provided with five adjusting holes along fan-shaped circular arc uniform intervals.
The invention has the beneficial effects as follows: by the position of lever for adjusting oil, make the through hole of control lever corresponding from different adjusting holes, inserting bolt fixes the angle of inclination of the valve plate that can regulate in ventilation duct again, thus regulate the air port size of ventilation duct, and then adjustment is through the cooling air quantity of ventilation duct, makes its air-distribution in less region even, between cold wind and sand material, carry out heat exchange fully, the use air quantity in accurate controlled cooling model region, improves cooling effect.
Accompanying drawing explanation
Fig. 1 is schematic top plan view of the present invention;
Fig. 2 is that the K of Fig. 1 is to close-up schematic view.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further.
See Fig. 1, Fig. 2, the present invention includes ventilation duct 1, rotating shaft 2 is provided with in ventilation duct 1, in ventilation duct 1, rotating shaft 2 is fixedly connected with valve plate 3, one end that ventilation duct 1 is stretched out in rotating shaft 2 is provided with adjustable plate 4 successively, control lever 5, adjustable plate 4 is sleeved in rotating shaft 2, adjustable plate 4 is fixedly connected with the outer wall of ventilation duct 1, one end of control lever 5 is fixedly connected with rotating shaft 2, the other end of control lever 5 is provided with through hole 6, adjustable plate 4 is provided with the adjusting hole 7 of some correspondences, bolt 8 is located through through hole 6 and any one adjusting hole 5, control lever 5 is perpendicular to the plane of valve plate 3, adjustable plate 4 comprises right angle fan-shaped panel, right angle fan-shaped panel is provided with five adjusting holes 5 along fan-shaped circular arc uniform intervals.
By the position of lever for adjusting oil 5, make the through hole 6 of control lever 5 corresponding from different adjusting holes 7, the angle of inclination of the fixing valve plate 3 that can regulate in ventilation duct 1 of inserting bolt 8 again, thus regulate the air port size of ventilation duct 1, and then adjustment is through the cooling air quantity of ventilation duct 1, makes its air-distribution in less region even, between cold wind and sand material, carry out heat exchange fully, the use air quantity in accurate controlled cooling model region, improves cooling effect.
