Description
Technical field
The present invention relates to a kind of dry sand air cooling equipment, specifically, for the cooling of common dry-mixed mortar industry dry sand, belong to dry-mixed mortar technical field.
Background technology
Common dry-mixed mortar is a kind of product that sand, cement, flyash, additive etc. are mixed in proportion, and the various parameters of sand have a great impact mortar quality.Wherein need reach≤0.5% requirement of water content, so roughing sand need be brought oven dry, but sand after drying can not be used for stirring immediately, because additive can produce chemical reaction when temperature is high, loses efficacy.Because the heat conductivility of sand is very poor, if the sand after drying temporarily first need not be stored in silo, wait cooling rear use, the temperature of so inner sand all can not have obvious reduction for a long time, the sand on surface also can have again moisture because of the condensation of hot gas, has influence on the quality of product.So the sand after drying needs a set of cooling device to lower the temperature to it.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby a kind of dry sand air cooling equipment is provided, can well reduce the temperature of sand, can well keep drying the water content of rear sand again, improved production efficiency, product quality is improved simultaneously.
According to technical scheme provided by the invention, dry sand air cooling equipment comprises cylindrical shell, rolling ring, motor and cam, welds rolling ring on cylindrical shell, and rolling ring both sides are provided with cam, and cam connects motor by power transmission shaft.Described driven by motor cam rotates, cam promotes rolling ring and rotates, and it is characterized in that: also comprise air inlet, air-valve, charging aperture, charging accelerator card, lifting blade, discharging scraper plate and feed box, cylindrical shell left end connects air inlet, air-valve is set in air inlet, and air inlet upper end connects charging aperture.In described cylindrical shell, left end spiral arranges charging accelerator card, fixing a plurality of lifting blades in cylindrical shell, and in cylindrical shell, right-hand member arranges discharging scraper plate.Described cylindrical shell right-hand member connects feed box.
Described feed box upper end connects air outlet, and lower end connects discharging opening.
Described lifting blade is arc.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Utilize air as cooling medium, cost is low; Good cooling results, has improved production efficiency, and product quality is improved.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Description of reference numerals: 1-air inlet, 2-air-valve, 3-charging aperture, 4-charging accelerator card, 5-lifting blade, 6-cylindrical shell, 7-rolling ring, 8-motor, 9-cam, 10-discharging scraper plate, 11-feed box, 12-air outlet, 13-discharging opening.
The specific embodiment
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1, the present invention mainly comprises air inlet 1, air-valve 2, charging aperture 3, charging accelerator card 4, lifting blade 5, cylindrical shell 6, rolling ring 7, motor 8, cam 9, discharging scraper plate 10, feed box 11.
Cylindrical shell 6 left ends connect air inlet 1, the interior air-valve 2 that arranges of air inlet 1, and air-valve 2 can be adjusted intake.Air inlet 1 upper end connects charging aperture 3.The interior left end spiral of described cylindrical shell 6 arranges charging accelerator card 4, for the dry sand to entering, accelerates to pass through, and prevents that dry sand is deposited in charging aperture 3 places.
On cylindrical shell 6, weld rolling ring 7, rolling ring 7 both sides are provided with cam 9, and cam 9 connects motor 8 by power transmission shaft.Motor 8 band moving cams 9 rotate, and cam 9 promotes rolling ring 7 and rotates.
The lifting blade 5 of the interior fixing a plurality of arcs of described cylindrical shell 6, the dry sand that enters cylindrical shell 6 by 5 pairs of lifting blades carries out water conservancy diversion, and the surface of dry sand is fully contacted with air, and the heat of dry sand is taken away by air as far as possible.
The interior right-hand member of described cylindrical shell 6 arranges discharging scraper plate 10.Cylindrical shell 6 right-hand members connect feed box 11, and feed box 11 upper ends connect air outlet 12, and lower end connects discharging opening 13.Discharging scraper plate 10, for stopping dry sand, falls dry sand and enters discharging opening 13.
Operation principle of the present invention is: when work, the dry sand of heat enters in cylindrical shell by charging aperture 3.Air enters cylindrical shell by air inlet 1, and air-valve 2 can be adjusted intake.In air-valve 2, air driven dry sand out enters the charging accelerator card 4 that spiral arranges, and dry sand Bu Hui cylindrical shell import department is piled up.The cam 9 that cylindrical shell 1 is driven by motor 8 promotes to rotate, and the dry sand being advanced by air driven is driven and stirs by lifting blade 5, and the surface of dry sand is fully contacted with air, and the heat of dry sand is taken away by air as far as possible.After last cooled dry sand is encountered discharging scraper plate 10, fall, from discharging opening 13, flow out.Air with dry sand temperature is drawn from top air outlet.The present invention is simple, compact and reasonable for structure; Utilize air as cooling medium, cost is low; Good cooling results, has improved production efficiency, and product quality is improved.
