According to the invention, the heating cavity is formed in the box body and used for improving cooled drying media by stopping and starting the steam heat exchanger, meanwhile, by means of increasing the effective height and control range of the cooler, the drying and cooling effects are improved, and the contraflow cooler can be used for cooling and drying of granular materials.
Description
Technical field
The present invention relates to a kind of materiel machining device, particularly a kind of cooler.
Background technology
Granulated feed cooler is the capital equipment that cools off and dehumidify through the hot wet feed of dried pellet again after being shaped to granulating, and the pellet temperature of just suppressing out from granulator is about 60～90 ℃, and moisture is about 10%～18%.Such pellet quality is soft, very easily cracked and rotten, must make the moisture of finished product be down to 10%～14% through super-dry and cooling, and temperature is down near room temperature (generally being no more than 3～5 ℃), ability packing, transportation and safe storage.
In the prior art, adopting cooler that pellet is lowered the temperature, dehumidified is simple and the most cheap method, its groundwork principle is: with air as cooling medium, air enters that its temperature and relative humidity change thereupon behind the cooler, cause the variation of moisture content and thermal capacity, along with the carrying out of cooling procedure, the ability that medium carries moisture and heat will constantly change, so the air through put amount of cooler, damp and hot counterbalance effect are to weigh the key criterion of cooling effect.
Different according to the flow direction of cooling material and cooling medium, cooler can be divided into downflow type, cross-flow type, reverse-flow and floated Four types substantially, wherein counterflow cooler is because of its good cooling results, the air that consumes is less and be usually used in the cooling of granule materials, the operation principle of counterflow cooler is: air stream stream is vertically reverse by material flow and material generation heat exchange from the bottom to top, material is carried out cooling down, but exist in actual applications, the equilibrium problem of cooling moisture, humidity and the output of Various Seasonal.In the winter time and wet season, adopting traditionally increases thickness of feed layer and reduces moisture, but has affected output; Adopt traditionally the thickness that reduces the bed of material to improve moisture in summer, but chilling temperature is higher.
Summary of the invention
The purpose of this invention is to provide a kind of counterflow cooler, improved the drying medium of cooling, increased effective depth and the modification scope of cooler, improved drying and cooling effect.
The object of the present invention is achieved like this: a kind of counterflow cooler, comprise the cooling box that is fixedly mounted on the frame, the casing bottom is connected with aggregate bin, the casing top offers charging aperture, the casing upper end offers exhaust outlet, the casing lower end offers air inlet, the charging aperture below is provided with the refining cone in the casing, bottom half is provided with slip grid and stationary grizzly, one end of described slip grid is connected on the output shaft of drive motors through eccentric wheel, be divided into drying chamber in the described casing from top to bottom, heating chamber and cooling chamber, be provided with steam heat-exchanger in the described heating chamber, the two ends of described steam heat-exchanger are separately installed with steam inlet and condensation-water drain.
When the present invention works, the material that is cooled enters from the charging aperture on casing top, behind the refining cone, fall in the casing, pass through successively from top to bottom drying chamber, heating chamber and cooling chamber, thereby having realized liquidating with the cold air that enters from casing lower end air inlet realizes heat exchange, has reduced the temperature of material, has played the effect of cool drying, the cooled material that is dried falls into aggregate bin, discharges from aggregate bin; In the winter time and wet season, can reduce moisture in the material by enabling steam heat-exchanger, thereby improve output; In summer, can improve the temperature that reduces material by adding condensed water to steam heat-exchanger, thereby improved output, compared with prior art, beneficial effect of the present invention is: the present invention arranges heating chamber in casing, by stopping and enabling the drying medium that steam heat-exchanger improves cooling, also increase effective depth and the modification scope of cooler simultaneously, improved drying and cooling effect.The present invention can be used in the cool drying of granule materials.
As improvement of the present invention, described steam heat-exchanger is condenser coil.It is simple in structure, and is with low cost.
Further improve as the present invention, be provided with level detector on the box body wall of described drying chamber section.So that can in time know the loading situation of material in the casing, when material surpassed the level detector position, level detector fed back to warning circuit with information, and operating personnel control feeder and stop feed.
As a further improvement on the present invention, described drive motors is reductor.Improve its power, further strengthened blanking velocity.
