Abstract
The utility model provides a drum -type sand cooling apparatus, which comprises a bracket, the cylinder, including a motor, an end cap, a controller, and a cover plate, its main points lie in that the cylinder is bilayer structure, be the sand passageway in the middle of the cylinder inlayer, it gos forward to promote sand by helical blade, the intermediate layer is the secondary refrigerant passageway, feed hopper is connected respectively in the both ends of cylinder inlayer with ejection of compact funnel, the secondary refrigerant import, the secondary refrigerant export is connected respectively in interbedded both ends, the business turn over opposite direction of direction and sand, the motor drives the cylinder and rotates, the motor is located the middle part of cylinder, the below design at cylinder both ends has the supporting wheel. The utility model has the advantages of, the cylinder inner wall is for double -deck hollow structure and install the hollow stirring vane of double helix, lets in the secondary refrigerant in inner wall and the blade, and sand gos forward to export orientation under helical blade's stirring after the import gets into the cylinder, continuous and inner wall and helical blade contact in the cylinder, thus the secondary refrigerant absorbs the heat of sand reaches the purpose that reduces the sand temperature. The utility model discloses throughput is big, cooling efficiency is high, the operation is reliable, the fault rate is low.
Description
Technical field
The utility model relates to the cooling device of the sand in a kind of Hydraulic and Hydro-Power Engineering industry component materials of concrete.
Background technology
At present, in pre cooling of concrete industry, only have a kind of cooling of equipment for component materials of concrete medium sand of screw cool sand machine by name, but because it is a kind of equipment be derived on the basis of conveying worm, the inherent defects such as the conveying worm handling capacity that it is inherited is low, easy blocking, disposal ability is not enough, cooling effectiveness is low to cause this equipment to occur when practice, and the problem such as easily break down, and thus can not meet requirement of engineering.
Meanwhile, its operating condition of drum-type sand cooling machine for domestic Sand Treating System in Lost-foam Casting is High-temperature cooling to normal temperature, and the general medium such as cold wet water smoke or cold wind that adopts, directly to the technique that sand cools, is not suitable for the cooling of Concrete Industry medium sand.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, thus provides one that sand can be made to be cooled to low temperature from normal temperature, and disposal ability is large, cooling effectiveness is high, the drum-type sand cooling radiator cooler of reliable, failure rate is low.
The technical scheme that the utility model adopts is a kind of drum-type sand cooling radiator cooler, it comprises support, cylinder, motor, its main points are that cylinder is double-decker, be sand passage in the middle of cylinder internal layer, promote sand by helical blade to advance, interlayer is refrigerating medium passage, loading hopper with go out the two ends that funnel is connected to cylinder internal layer, refrigerating medium import, refrigerating medium outlet are connected to the two ends of interlayer, direction is contrary with the turnover direction of sand, driven by motor cylinder rotates, and motor is positioned at the middle part of cylinder, and the envisaged underneath at cylinder two ends has support wheel.
The utility model improves on the basis of existing drum agitation device, and cylinder is made double-decker refrigerating medium is introduced cylinder, cool the sand of internal layer, cooling effectiveness is high, reliable, and disposal ability is large.
Also heat-insulation layer is enclosed with outward at cylinder.Heat-insulation layer is the cooling effect affected sand to prevent refrigerating medium from carrying out heat exchange in air.
The helical blade being fixed on inner wall of rotary drum is also double-decker, and there is refrigerating medium passage centre.Helical blade also participates in the cooling to sand, is conducive to improving cooling effectiveness.
The utility model has the advantage of, inner wall of rotary drum is double-layer hollow structure and installs the hollow stirring vane of double helix, refrigerating medium (ethylene glycol solution) is passed in inwall and blade, sand to enter after cylinder under the stirring of helical blade while advance to Way out from import, constantly contact with inwall and helical blade while spin upside down in cylinder, increase adherent rate, refrigerating medium absorbs the heat of sand thus reaches the object reducing sand temperature in the process.Disposal ability is large, cooling effectiveness is high, reliable, failure rate is low.
Accompanying drawing explanation

Detailed description of the invention
Below in conjunction with view, the utility model is described in detail
As shown in Figure 1, 2, a kind of drum-type sand cooling radiator cooler, improve on the basis of existing cylinder 2 agitating device, cylinder is made double-decker refrigerating medium is introduced cylinder, it comprises support 10, cylinder 2, motor 9, cylinder 2 is double-decker, be sand passage in the middle of cylinder internal layer 11, promote sand by helical blade 8 to advance, interlayer 12 is refrigerating medium passage, the helical blade 8 being fixed on inner wall of rotary drum is also double-decker, and its cavity is by cylinder internal layer and interlayer UNICOM, and centre has refrigerating medium to pass through.Loading hopper 1 with go out the two ends that funnel 3 is connected to cylinder internal layer 11, refrigerating medium import 4, refrigerating medium outlet 5 are connected to the two ends of interlayer 12, the turnover direction of refrigerating medium is contrary with the turnover direction of sand, motor 9 drives cylinder 2 to rotate, motor 9 is positioned at the middle part of cylinder 2, the envisaged underneath at cylinder 2 two ends has support wheel 6, can determine the support wheel quantity that uses according to the length of cylinder and weight.
Heat-insulation layer 7 is also enclosed with outside cylinder 2.Heat-insulation layer is the cooling effect affected sand to prevent refrigerating medium from carrying out heat exchange in air.
Sand enters after cylinder 2 from left side loading hopper 1 and go out the advance of funnel 3 direction to opposite side under the stirring of helical blade 8; Refrigerating medium (the low-temperature glycol solution produced by screw rod ethylene glycol unit) enters inner wall of rotary drum double-layer hollow interlayer and spiral hollow stirring vane from right side refrigerating medium import 4 simultaneously, advance to the left, stirred up and down by the hollow stirring vane of double helix, sand is fully contacted with inner wall of rotary drum and helical blade, and produce heat exchange with refrigerating medium, sand cooling but after flow out from going out funnel 3, the refrigerating medium after heat exchange is got back to screw rod ethylene glycol unit and is again cooled rear for next heat exchange after refrigerating medium outlet 5 is flowed out.
