A resin hopper and a curing agent feeding pipe are respectively arranged on a top cover main body; a resin hopper gate is arranged on the resin hopper; the curing agent feeding pipe comprises a feeding hopper; the lower end of the feeding hopper is connected with a thin and long pipe extending into the top cover main body; the tail end of the thin and long pipe is provided with a bending pipe.
Description
Technical field
The utility model relates to precoated sand production equipment technical field, is specially the top cover 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, resin and curing agent are mixed, resin and curing agent is uniformly distributed and is effectively coated on sand grain surface.Roughing sand is heated to be discharged into puddle mixer after uniform temperature, then can add resin, but the roughing sand temperature that adds resin to be is very crucial, it is relevant with resin softening point and viscosity, the overheated oxidization burning loss of the too high resin of sand temperature, too low resin can not all melt, thereby can not all be wrapping to grains of sand surface, has reduced the quality of precoated sand.Add the object of curing agent to be that under solidification temperature, it can solidify the linear structure of resin, but the precoated sand of producing does not allow to add curing agent and resin generation curing reaction, curing reaction can only carry out when user makees core in the mould of heating, therefore add the temperature of curing agent very crucial, the temperature that this temperature should be decomposed lower than curing agent and the temperature being cured with resin, yet the sand temperature while adding curing agent is too low, curing agent water is easy to moisture and can not fully evaporates, and also can reduce the quality of precoated sand.Existing puddle mixer adopts a throat-fed conventionally, single port charging will impact the temperature of the mixing of resin and curing agent and sand at charging aperture place, and then affect the quality of precoated sand, simultaneously curing agent add method very important, need to reach the object of even hybrid resin and curing agent and sand.
Utility model content
For the problems referred to above, the utility model provides the top cover of coated sand mixer, it,, according to adding the difference of material that different charging apertures is set respectively, guarantees that resin and curing agent and sand can fully mix, and can not impact the temperature of the mixing of resin and curing agent and sand simultaneously.
Its technical scheme is such: comprise top cover body, it is characterized in that: on described top cover body, be respectively equipped with resin bucket and curing agent inlet pipe, described resin bucket is provided with resin bucket gate, described curing agent inlet pipe comprises feed hopper, described feed hopper lower end is connected with the elongated tubular that extends into described top cover body, and the tail end of described elongated tubular is provided with bending tube.
It is further characterized in that: the central authorities of described top cover body are provided with exhaust duct, and described exhaust outlet goes out to be provided with volume adjusting apparatus;
Described volume adjusting apparatus comprises being arranged on and in exhaust duct, is provided with rotating shaft, in exhaust duct, in described rotating shaft, be fixedly connected with valve plate, one end that described exhaust 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 exhaust 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 setting is through described through hole and adjusting hole described in any one.
The beneficial effects of the utility model are: design a plurality of charging apertures in order to add different materials, when being provided with resin bucket gate sealing resin bucket can prevent puddle mixer mulling when not putting sand on resin bucket, inner dust from flying is to environment, curing agent inlet pipe is arranged on the elongated tubular of feed hopper lower end and guarantees that curing agent solution slowly adds uniformly, fully mix with sand and resin, the bending tube of elongated tubular afterbody can prevent that air-flow from driving in the wrong direction and scurries out from charging aperture.
