Abstract
The present invention discloses an air-energy unpowered grain drying equipment, which comprises a drying barrel and a heating device. The drying barrel comprises a material feeding section, a drying section and a material discharging port. The material feeding section is arranged above the drying section. The material discharging section is arranged underneath the drying section. The drying section is a cone structure with a big upper part and a small lower part. The drying section comprises an inner cone-shaped sieve and an outer cone-shaped sieve which are arranged in a coaxial manner. The inner cone-shaped sieve and the outer cone-shaped sieve are provided with densely distributed sieve meshes . An air inlet pipe is arranged in the center of the material feeding section. The lower end of the air inlet pipe is hermetically connected with the upper end of the inner cone-shaped sieve through a transition connecting piece. A spiral sieve baffle is arranged on the inner wall of the outer cone-shaped sieve. The heating device comprises a compressor, a condenser, a liquid accumulator, a dry filter, a throttle valve, an evaporator and a gas-liquid separator which are sequentially communicated with each other. The gas-liquid separator communicated with the compressor to form a closed circulation system. The condenser is arranged in the air inlet pipe, and an air fan is arranged in the air inlet pipe. The drying equipment in the present invention does not need mechanical power and has characteristics of good drying quality and high drying efficiency.
Description
Technical field
The invention belongs to agriculture field, be specifically related to a kind of air energy non-power grain drying plant.
Background technology
China is vast in territory, You Shiyige large agricultural country, production and the storage of grain have a long history, according to China's a large amount of unearthed historical relic and historical Textual Research over nearly 50 years, China's infant farming was imparted rudimentary knowledge to beginners the late period Old Stone Age, developed in the epoch new period (apart from modern about approximately 10,000 years).And the storage of grain is the continuation of agricultural cultivation, storage technology is to be accompanied by agriculture development.After entering the epoch new period, along with the development of infant farming, agricultural production reaches a certain scale, and residue has appearred in grain, just by grain processing, develops into storage gradually.And grain heat-drying is the important component part of View of Grain Storage Technoiogy.
Before foodstuff preservation, must remove the moisture content of grain, traditional grain heat-drying adopts the mode of artificial airing, and this kind of mode wastes time and energy, and must rely on good weather, usually causes grain not dried in time and causes grain to rot.Modern people have invented a lot of grain drying devices, and these equipment mostly need machine power, and usually adopt electrically heated mode to toast, and usually cause grain drying inhomogeneous.
Summary of the invention
The object of the invention is to provide a kind of air energy non-power grain drying plant, solves the baking of existing grain heat-drying inhomogeneous and need mechanokinetic problem.
Technical scheme of the present invention is: a kind of air energy non-power grain drying plant, comprise and dry bucket and heater, described oven dry bucket comprises feed zone, drying section and discharge gate, feed zone is arranged on the top of drying section, discharge gate is arranged on the below of drying section, the taper that drying section is big up and small down, described drying section comprises inner conical sieve and the male-tapered sieve of coaxial setting, on inner conical sieve and male-tapered sieve, be densely covered with sieve aperture, described feed zone center is provided with blast pipe, blast pipe lower end and inner conical sieve upper end are tightly connected through transition piece, on described male-tapered sieve inwall, be provided with helical baffle, described heater is by the compressor being communicated with in turn, condenser, reservoir, device for drying and filtering, choke valve, evaporimeter, gas-liquid separator forms, gas-liquid separator is communicated with the closed circulation system forming with compressor, described condenser is arranged in blast pipe, and in blast pipe, be provided with blower fan.
The present invention compared with prior art tool has the following advantages:
1, the annular space that material is formed by barrel and the blast pipe outer wall of feed zone enters in the drying channel that inner conical sieve and male-tapered sieve form, and relies on gravity Uniform Flow, then is discharged by discharge gate.It is upper that hot blast enters inner conical sieve by blast pipe, under the effect of hot-blast pressure, through inner conical sieve, enters in drying channel, and discharge from male-tapered sieve.Hot blast completes the wet exchange of heat while passing drying channel, take away grain moisture content.Grain flows from top to bottom, completes grain heat-drying.
2, due to inner conical sieve with male-tapered sieve is coaxial arranges, on the horizontal section of each drying channel, hot blast can be uniformly distributed, and has guaranteed that the time that grain contact with hot blast is identical, thereby precipitation range equates, has improved the water uniformity after grain baking.Because the big up and small down pyramidal structure of drying section makes grain, can rely on gravity just can discharge outside baking zone, without power is set, grain, not through mechanical agitation and high-speed friction, effectively reduces the fragmentation of grain simultaneously, has guaranteed to dry the quality of grain.
3, the annular space that material is formed by barrel and the blast pipe outer wall of feed zone enters in the drying channel that inner conical sieve and male-tapered sieve form, and relies on gravity Uniform Flow, then is discharged by discharge gate.It is upper that hot blast enters inner conical sieve by blast pipe, under the effect of hot-blast pressure, through inner conical sieve, enters in drying channel, and discharge from male-tapered sieve.Hot blast completes the wet exchange of heat while passing drying channel, take away grain moisture content.Grain flows from top to bottom, completes grain heat-drying.Due to inner conical sieve with male-tapered sieve is coaxial arranges, on the horizontal section of each drying channel, hot blast can be uniformly distributed, and guaranteed that the time that grain contact with hot blast is identical, thereby precipitation range is equal, has improved the water uniformity after grain baking.Because the big up and small down pyramidal structure of drying section makes grain, can rely on gravity just can discharge outside baking zone, without power is set, grain, not through mechanical agitation and high-speed friction, effectively reduces the fragmentation of grain simultaneously, has guaranteed to dry the quality of grain.
4, on male-tapered sieve inwall, be provided with helical baffle, can increase material in the time of staying of drying section, meanwhile, due to the existence of helical baffle, material can produce the effect of rolling, strengthens drying effect.
5, heater consists of the compressor being communicated with in turn, condenser, reservoir, device for drying and filtering, choke valve, evaporimeter, gas-liquid separator, gas-liquid separator is communicated with the closed circulation system forming with compressor, described condenser is arranged in blast pipe, and is provided with blower fan in blast pipe.By air energy heat pump, produce hot-air material is dried, because the air energy heat pump thermal efficiency is high, therefore more energy-efficient than traditional electrical heating.
