Description
Technical field
The present invention relates to a kind of dry sand air cooling equipment, specifically be used for the cooling of common dry-mixed mortar industry dry sand, belong to the 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 very big influence to the mortar quality.Wherein water content need reach≤0.5% requirement, so roughing sand need be brought oven dry, but the sand after the oven dry can not be used for stirring immediately, loses efficacy because additive when temperature is high, can produce chemical reaction.Because the heat conductivility of sand is very poor; If the sand after the oven dry temporarily need not be stored in the silo earlier, wait cooling back usefulness, the temperature of so inner sand all can not have obvious reduction for a long time; The sand on surface also can have moisture again because of the condensation of hot gas, has influence on the quality of product.So the sand after the oven dry needs a cover cooling device that it is lowered the temperature.
Summary of the invention
The objective 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 back sand simultaneously again, improved production efficiency, product quality is improved.
According to technical scheme provided by the invention, the dry sand air cooling equipment comprises cylindrical shell, rolling ring, motor and cam, welds rolling ring on the cylindrical shell, and the rolling ring both sides are provided with cam, and cam connects motor through power transmission shaft.Said 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, the cylindrical shell left end connects air inlet; Air-valve is set in the air inlet, and the air inlet upper end connects charging aperture.The left end spiral is provided with the charging accelerator card in the said cylindrical shell, fixing a plurality of lifting blades in the cylindrical shell, and right-hand member is provided with the discharging scraper plate in the cylindrical shell.Said cylindrical shell right-hand member connects feed box.
Said feed box upper end connects air-vent, and the lower end connects discharging opening.
Said lifting blade is an arc.
Compared with present technology 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.
Description of drawings
Fig. 1 is a 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
Following the present invention will combine the embodiment in the accompanying drawing to further describe:
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, and air-valve 2 is set in the air inlet 1, and air-valve 2 can be adjusted intake.Air inlet 1 upper end connects charging aperture 3.The left end spiral is provided with charging accelerator card 4 in the said cylindrical shell 6, is used for the dry sand that gets into is quickened to pass through, and prevents that dry sand is deposited in charging aperture 3 places.
Welding rolling ring 7 on the cylindrical shell 6, rolling ring 7 both sides are provided with cam 9, and cam 9 connects motor 8 through power transmission shaft.Motor 8 drives cam 9 and rotates, and cam 9 promotes rolling ring 7 and rotates.
The lifting blade 5 of fixing a plurality of arcs in the said cylindrical shell 6 carries out water conservancy diversion through 5 pairs of dry sands that get into cylindrical shell 6 of lifting blade, makes the surface of dry sand fully contact with air, makes the heat of dry sand taken away by air as far as possible.
Right-hand member is provided with discharging scraper plate 7 in the said cylindrical shell 6.Cylindrical shell 6 right-hand members connect feed box 11, and feed box 11 upper ends connect air-vent 12, and the lower end connects discharging opening 13.Discharging scraper plate 7 is used to stop dry sand, makes dry sand fall and gets into discharging opening 13.
Operation principle of the present invention is: when work, the dry sand of heat gets in the cylindrical shell through charging aperture 3.Air gets into cylindrical shell through air inlet 1, and air-valve 2 can be adjusted intake.The air driven dry sand that comes out in the air-valve 2 gets into the charging accelerator card 4 that spiral is provided with, and makes dry sand can not pile up in cylindrical shell import department.Cylindrical shell 1 is promoted to rotate by the cam 9 that motor 8 drives, and the dry sand that is advanced by air driven is stirred by lifting blade 5 drives, makes the surface of dry sand fully contact with air, and the heat of dry sand is taken away by air as far as possible.Fall after last cooled dry sand is run into discharging scraper plate 10, from discharging opening 13, flow out.The air that has a dry sand temperature then from top air-vent draw.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.
