Abstract
The invention provides a hot sand cooling and drying device. The hot sand cooling and drying device comprises a dry sand cabin, a sand shakeout baffle, sand shakeout bags and a cooling drier, wherein the sand shakeout baffle is arranged in the dry sand cabin to divide the dry sand cabin into an upper part and a lower part; sand shakeout holes are distributed on the sand shakeout baffle; one sand shakeout bag is arranged on the bottom surface of the sand shakeout baffle corresponding to each sand shakeout hole; and the cooling drier is arranged outside the dry sand cabin and connected with the part of the dry sand cabin below the sand shakeout baffle through a circulating pipeline. In the device, hot sand dropping in the bag is cooled and dehumidified through air circulation by the cooling drier, and the permeability of the sand and the cloth bag and the temperature difference formed by the cooling drier are fully utilized, so that the moisture and the heat in the hot sand are quickly evaporated and the device has the characteristics of high cooling speed and good drying effect.
Description
Technical field
The present invention relates to be used in a kind of Foundry Production the dry device of hot sand cooling, belong to the but technical field of drying of hot sand cooling in the casting.
Background technology
Used sand needed heating removing the moisture in the sand before carrying out resin sand preparation in the Foundry Production, and then cooled to below 40 ℃, could get into the puddle mixer use.At present; Method to the sand cooling is in hot sand, to place cooling tube; Feed media such as cooling water in the cooling tube, yet the problem that this type of cooling exists is that the cooling tube outer wall is prone to condensed water, even more serious when especially the sand oven dry is not thorough; The core that causes processing or the intensity of sand mold obviously reduce, and this method cooling velocity is slower.
Summary of the invention
To the but problem that exists of technology of hot sand cooling in the existing Foundry Production, the present invention provides a kind of cooling velocity fast and can make hot sand further obtain but drying device of dry hot sand cooling.
Hot sand cooling of the present invention but drying device adopts following technical solution:
This hot sand cooling but drying device comprises dry sand storehouse, knockout dividing plate, knockout bag and cooling driers; The knockout dividing plate is arranged in the dry sand storehouse; The dry sand storehouse is divided into two parts up and down; Be distributed with drop-hole on the knockout dividing plate, corresponding each drop-hole is provided with a knockout cloth bag on the bottom surface of knockout dividing plate, and cooling driers is arranged on the outside of dry sand storehouse and is connected with the part of dry sand storehouse below the knockout dividing plate through circulation line.
Dry sand storehouse inwall below the bottom surface of knockout dividing plate and the knockout dividing plate is provided with thermal insulation layer, in case produce condensed water.
Series shaft flow fan in cooling driers and the circulation line that the dry sand storehouse is connected, accelerating air circulation, the outflow of just can condensing of airborne moisture and condenser in cooling driers.
The escape pipe of cooling driers gets into the dry sand storehouse with the tangential, and exhaust tube is connected with the filter bowl that is arranged on dry sand storehouse lower central.
Be provided with flange-cooled electrically heated rod in the knockout bag, so that directly be used for the drying of damp sand.
The present invention lowers the temperature through the air circulation cooling and dehumidifying to the hot sand that falls in the cloth bag with cooling driers; The gas permeability of sand and cloth bag and the temperature difference that cooling driers forms have been made full use of; Make that moisture and heat evaporate rapidly in the hot sand, have the advantages that cooling velocity is fast, drying effect is good.

Wherein: 1, dry sand storehouse, 2, the knockout dividing plate, 3, the knockout bag, 4, thermal insulation layer, 5, cooling driers, 6, cold dried chamber, 7, filter bowl, 8, drop-hole.
The specific embodiment
As depicted in figs. 1 and 2; Hot sand cooling of the present invention but drying device comprises dry sand storehouse 1, knockout dividing plate 2, knockout bag 3 and cooling driers 5; Knockout dividing plate 2 is arranged on the middle and lower part in dry sand storehouse 1; Be distributed with several drop-holes 8 (referring to Fig. 2) on the knockout dividing plate 2, corresponding each drop-hole 8 is equipped with a knockout bag 3 on the bottom surface of knockout dividing plate 2.Dry sand storehouse 1 can be described as cold dried chamber 6 in the part of knockout dividing plate below 2, and the inwall of the bottom surface of knockout dividing plate 2 and cold dried chamber 6 is provided with thermal insulation layer 4.Cooling driers 5 is arranged on the outside in dry sand storehouse 1, and is connected with cold dried chamber 6 through circulation line, for accelerating air-flow circulation, series shaft flow fan in circulation line.The escape pipe of cooling driers 5 gets into cold dried chamber 6 with the tangential, and exhaust tube is connected with the filter bowl 7 at 6 centers, cold dried chamber.
If the isometric flange-cooled electrically heated rod of a suitable power is set in each knockout bag 3, device of the present invention can directly be used for the drying of damp sand.
The course of work of the present invention is:
The sand of heating behind the preliminarily dried dropped on the knockout dividing plate 2 by the top in dry sand storehouse 1, get into knockout bags 3 by the drop-hole on the knockout dividing plate 28, by the cold dried chamber 6 of 1 bottom, knockout bag 3 hanging dry sand storehouses, lower ending opening.Have certain space between the knockout bag 3, and knockout bag 3 breathes freely also, through the cooling that circulates of the air between 5 pairs of knockout bags 3 of cooling driers, sand heat and moisture content in landing at intermittence process evaporate simultaneously, and moisture becomes condensed water and flows out in cooling driers.Sand is lowered the temperature rapidly when obtaining drying.Sand after the cooling gets into puddle mixer by 1 bottom, dry sand storehouse.
The type of cooling that the present invention adopted is different fully with prior art, is characterized in when hot sand cooling is but lowered the temperature, having extracted the moisture in the sand, makes sand further obtain drying.Solved the problem that prior art is only lowered the temperature and do not dehumidified, and energy-conservation obvious, be specially adapted to the big area of tropical high temperature air humidity in rainy season.
