Description
Technical field
the present invention relates to a kind of cooler of batch (-type) grain and oil material.
Background technology
at present, grain and oil material (sesame, tea seed, walnut kernel, linseed, soybean, vegetable seed etc.) through drying, cool again, finally store, cooling is wherein the requisite link of material storing, in prior art, the cooling means of grain and oil material take machinery as Main Means, adopt corresponding technique and technical measures, control temperature, under the prerequisite not damaging grain and oil materials quality, reduce the heat in material, the too high generation oxidation reaction of material Yin Wendu or heating etc. is avoided to cause materials quality to reduce and dry loss, make it reach national security stock standard and be called grain and oil material cooling technology, therefore cooling technology can be regarded as the final stage work of grain and oil drying materials or dry work, the independent work that grain and oil material is processed can certainly be regarded as.
in the process for cooling of grain and oil material, application is carry out heat exchange by constantly passing into cold air stream in material more widely, makes material heat release, and cold air absorbs heat, the object of material cooling is reached with this, this take air as cooling medium, carries out heat exchange, make it fall daybreak with the mode of convection current and grain and oil material, thus reach the object of cooling, be called convection current cooling method, being the cooling technology generally applied now, is also main cooling technology.
existing grain and oil material cooling machine tool, mainly continuous flowing type cooler, its feature is that grain and oil material resting state in cooler presents continuity, is applied to large-scale production, and as soybean, vegetable seed etc., the difference according to cooling frame for movement is classified as follows:
(1), storehouse formula cooler, be, in round silo, the cooling devices such as air-supply, ventilative, air-out are installed, the material just through drying in warehouse entry material or storehouse cooled.Shortcoming is that equipment is complicated, and equipment investment is large.
(2), cross-flow type cooler, its design feature is, material by gravity to downstream to cooling section, cold air is forced to be horizontally through grain layer by inlet air plenum, the holdup time of material in cooler and material flow can utilize the rotating speed of grain discharging wheel or grain extraction unloading auger to control, and material flow depends primarily on temperature and the coolant temperature of material.The subject matter existed is: inhomogeneous cooling is even, and the material of inlet side is excessively cold, and exhaust side then cools deficiency, creates temperature difference, and be secondly that specific energy consumption is higher, heat exchange is insufficient, and namely cooling effectiveness is low.
(3), downflow type cooler, cold wind and material move downward simultaneously, do not have screen cloth to hold in the palm material in cooler, material relies on gravity to flow downward, and the following current cooler of a single-stage generally has an air-cooler, and waste gas directly enters air, because grain layer is thicker, gas-flow resistance is large.Shortcoming is that power of fan used is comparatively large, and energy consumption is high.
(4), counterflow cooler, be generally made up of a round storehouse and Porous Base, wet grain is fed by Cang Ding, cold wind utilizes blower fan to enter grain layer through orifice plate at the bottom of storehouse, carries out cooling operations, good cooling results, heat exchanger effectiveness is high, and shortcoming is that device structure is complicated, and control system requires high.
(5), straight line cooler, be in rectangular cooling chamber or tunnel in cross section, install belt-type conveying equipment, conveyer belt mostly is netted, and air-flow becomes cross-flow with material, and conveyer belt is in reach process, and material constantly contacts with cold air and is cooled.Require ulking thickness, the loading density uniformity brought, otherwise it is uneven to ventilate, and product quality is declined.The production capacity of this cooler and heat exchange efficiency are all lower, require higher to the operative skill of operating personnel.
(6), turning circle cartridge type cooler, its major part is slightly in the rotor tilted with horizontal line.Material is sent into from one end that rotating cylinder is higher, flow contact with the cold air entered, along with the rotation of cylinder, material is cooled complete when flowing to lower one end under gravity and sends, some pieces of flights usual cylinder inner wall are equipped with, effect is spilt down after being taken up by material again, to increase frigorimeter area, cooldown rate is increased, also impel material to run forward simultaneously, when cylinder rotates a circle, material is taken up and is spilt next time, and the distance that material advances equals the slope that its height fallen is multiplied by cylinder.Shortcoming is: equipment is heavy; Metal material consumption is many; The thermal efficiency is low, is about 50%; Complex structure, floor space is large; Drive disk assembly needs often maintenance etc.
(7), fluid bed cooler, grain is in charging aperture ingress engine, and move continuously forward along the sieve tilted under the action of the forces of the wind, the inclination angle of sieve adjusts by adjusting bolt, cold wind cools grain through sieve, because need to air blast in fluid bed, to make material be flow regime, make intrasystem dust easily with slit source to environment, workshop dust is more, need an exhaust blower that air in machine is discharged in addition, equipment investment increases, and energy consumption is high.
be more than the feature of existing main grain and oil material cooling machine tool, shortcoming is more outstanding.
in sum, existing main grain and oil material cooling machine tool has respective feature, but also there is relatively more outstanding shortcoming, be not suitable for the cooling to special oils such as sesame, tea seed, walnut kernel, linseeds, the feature of this kind of material is: output is little, is worth large, therefore will notes not damaging material during process, technological parameter requires strict, small lot process, environmental sanitation requires high, therefore according to these requirements, summary draws, the shortcoming of existing main grain and oil material cooling machine tool is:
(1), equipment is complicated, and equipment investment is large, and control system requires high, requires higher to the operative skill of operating personnel.
(2), cooling effect is bad, and efficiency is low.
(3), power of fan used is comparatively large, and energy consumption is high, or needs to increase exhaust blower.
(4), operating environment dust is many, and sanitary condition is poor.
