Description
Technical field
The utility model relates to a kind of dry sand air cooling equipment, specifically is used for the cooling of common dry-mixed mortar industry dry sand, belongs 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 a great impact 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 can produce chemical reaction when temperature is high.Because the heat conductivility of sand is very poor, if the sand after the oven dry temporarily need not be stored in the silo first, wait the rear usefulness of cooling, 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 the oven dry needs a cover cooling device that it is lowered the temperature.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of dry sand air cooling equipment is provided, and can well reduce the temperature of sand, can well keep drying again simultaneously the water content of rear sand, has improved production efficiency, and product quality is improved.
According to the technical scheme that the utility model provides, 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 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, 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 arranges the charging accelerator card in the described cylindrical shell, fixing a plurality of lifting blades in the cylindrical shell, and right-hand member arranges the discharging scraper plate in the cylindrical shell.Described cylindrical shell right-hand member connects feed box.
Described feed box upper end connects air-vent, and the lower end connects discharging opening.
Described lifting blade is arc.
Compared with the prior art the utility model has the following advantages:
The utility model 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 the utility model structural representation.
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 utility model is further described in connection with the embodiment in the accompanying drawing:
As shown in Figure 1, the utility model 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 air inlet 1 interior air-valve 2 that arranges, and air-valve 2 can be adjusted intake.Air inlet 1 upper end connects charging aperture 3.Described cylindrical shell 6 interior left end spirals arrange charging accelerator card 4, are used for the dry sand that enters is accelerated to pass through, and prevent 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 by power transmission shaft.Motor 8 band moving cams 9 rotate, and cam 9 promotes rolling ring 7 and rotates.
The lifting blades 5 of described cylindrical shell 6 interior fixing a plurality of arcs, the dry sand that enters cylindrical shell 6 by 5 pairs of lifting blades carries out water conservancy diversion, so that the surface of dry sand fully contacts with air, so that the heat of dry sand is taken away by air as far as possible.
Described cylindrical shell 6 interior right-hand members arrange discharging scraper plate 7.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 for stopping dry sand, enters discharging opening 13 so that dry sand falls.
Operation principle of the present utility model is: when work, the dry sand of heat enters in the cylindrical shell by charging aperture 3.Air enters cylindrical shell by air inlet 1, and air-valve 2 can be adjusted intake.Out air driven dry sand enters the charging accelerator card 4 that spiral arranges in the air-valve 2, so that dry sand can not piled 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, so that the surface of dry sand fully contacts with air, 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.Air with the dry sand temperature is then drawn from the top air-vent.The utility model 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.
