Abstract

The invention relates to equipment which is applied to an evanescent die casting production line and used for conveying and cooling sand in a sand box, in particular to a spiral conveying cooler to mainly solve the problem that an existing cooler is not good in cooling effect. The spiral conveying cooler comprises a support, a motor speed reducer, a drive riding wheel, a driven riding wheel, a small riding wheel and a barrel. A front barrel end cover and a back barrel end cover are fixed to the support, the front barrel end cover is provided with a sand inlet, the back barrel end cover is provided with a sand outlet, the front end of an air pipe in the barrel is fixed to the front barrel end cover, the back end of the air pipe in the barrel stretches out of the back barrel end cover, the air pipe is provided with an air outlet hole, and the back barrel end cover is provided with an air outlet. A towing belt support is fixed to the outer wall of the barrel, a towing belt is fixed to the towing belt support, and the towing belt is meshed with the front drive riding wheel and the driven riding wheel. A limiting ring is arranged on the outer wall of the barrel, a limiting wheel is installed on the support through a shaft, and the limiting wheel is located outside the limiting ring. The spiral conveying cooler has the advantage of being good in cooling effect.

Description

A kind of helical feed cooler

Technical field:

The present invention relates to one and be applied on Lost Form Casting Production Line, the sand in sandbox is carried and cooling equipment.

Background technology:

That on the cooling machine cylinder body inwall using on Lost Form Casting Production Line at present, is interrupted is provided with pilot blade, and one end of cylindrical shell is ventilation inlet, and the other end is air outlet, S. A. is located in cylindrical shell, and S. A. rotation, drives barrel body rotation, advancing in rotation limit, sand limit in cylindrical shell, discharges from sand export.Its weak point is, S. A. is located in cylindrical shell, takies barrel space; What pilot blade was interrupted is arranged on cylinder inboard wall, can only play directional tagging, and can not extend the time that sand passes through in cylindrical shell, makes cooling-down effect bad.

Summary of the invention:

Technical matters to be solved by this invention is to provide and a kind ofly can extends the travel time of sand in cylindrical shell, good cooling effect, the helical feed cooler of long service life.

Above-mentioned purpose is achieved in that it comprises support, motor reducer is fixed on support, transmission shaft is contained on support by bearing, motor reducer power take-off shaft is connected by coupler with transmission shaft, active roller station is contained on transmission shaft, driven shaft is also contained on support by bearing, driven support roller is contained on driven shaft, on support between active roller station and driven support roller, be fixed with little supporting-roller shaft, little support roller is contained in little supporting-roller shaft, also comprise cylindrical shell, on cylinder inboard wall, be fixed with flight, the bottom of cylindrical shell is placed on little support roller, barrel front end has conveyor front barrel end shield, cylinder back-end has rear cylinder body end shield, before, rear cylinder body end shield is all fixed on support, all moving contacts of cylindrical shell end shield at cylindrical shell and its two ends, conveyor front barrel end shield is provided with sand inlet, rear cylinder body end shield is provided with sand export, in cylindrical shell, also has airduct, the front end of airduct is fixed on conveyor front barrel end shield, stretch out from rear cylinder body end shield the rear end of airduct, on airduct, have several exhaust vents, rear cylinder body end shield is provided with air outlet,

Also comprise two annular traction supports, after two traction supports are set on the cylinder body outer wall of active roller station and driven support roller top and cylinder body outer wall be connected and fixed, article two, annular traction is separately fixed on two traction supports, and two tractions are all meshed with foregoing active roller station and driven support roller;

On cylinder body outer wall, be also fixed with limit coil, position-limited wheel is rack-mount by axle, and position-limited wheel is positioned at limit coil outside, can play position-limiting action to cylindrical shell.

Described active roller station and driven support roller are all made of automotive wheel.

Advantage of the present invention is: when use, the rear end of this device airduct is connected with blower fan by flexible pipe, air outlet is connected with dust exhaustor by flexible pipe, motor reducer work, drives active roller station rotation, thereby drives barrel body rotation.Owing to being provided with flight on cylinder inboard wall, so can extend the travel time of sand in cylindrical shell, and wind discharges from the air outlet that is located at same one end with air intake out from the exhaust vent of airduct, and it is long that wind and sand carry out time of interchange of heat, so good cooling effect.Owing to being provided with traction support between traction and cylindrical shell, thus can lower the temperature to traction, thus increase the service life.Because its active roller station and driven support roller are all made of motor tire, so noise is little when work.
