Abstract
The utility model relates to a revolving drum machine for multi-period number drying, which is essentially used for dying granular material such as chemical fertilizers, feed stuff and the like, utilizing the multi-period number drying mode, namely a warm-air air inlet hole and an air outlet hole are arranged on each dying period number, a short coming of a revolving drum machine of an original dying period number is overcome, low-temperature big air quantity effect is achieved by adding the dying period numbers, various inorganic fertilizer, fertilizer, and ecological fertilizer can be dried, and loss and denaturation of nitrogen fertilizer and phosphate fertilizer in the process of dying are reduced, the utility model can be assembled with the other relative equipments in parallel, and one machine with multifunction is achieved.
Description
Technical field
The utility model relates to a kind of drying equipment, especially relates to a kind of revolving drum drier that is used for particulate materials such as chemical fertilizer, feed.
Background technology
At present, be used for chemical fertilizer, the drying equipment of granular products such as feed mostly is the turning circle cartridge type, with reference in " drying equipment design " (Shanghai science tech publishing house) book about the structure explanation of revolving drum machine, and utility model patent " four unification revolving drum machines " ZL:96231468.4 awards a certificate day: 1997.4.10, " the spherical particle manufacturing equipment of comprehensive function " ZL:98242860.X, award a certificate day: 2000.7.28, the wherein disclosed structure that is used for dry revolving drum machine, all adopt a dry section, promptly have only a hot blast import and a tail gas outlet, this has just determined the hot blast of air inlet to need higher temperature just can reach the purpose of dried material, cause nitrogenous fertilizer and phosphate fertilizer than lossy, nor can satisfy fertilizer and ecological fertile drying condition, and the disclosed revolving drum machine of above two granted patent is all opened pore as gas channel on cylindrical wall, its shortcoming is: under the prerequisite that guarantees cylinder strength, in the passage that all angles are opened, can only there be a few passage that faces toward air outlet to be in ventilation state, tail gas is forming big windage by Kong Shihui like this, the result is dry motive force deficiency, output is not enough, because the high speed and high pressure air-flow at passage place is taken a large amount of dust granules outside the cylindrical shell out of, after dust granules enters airduct, amass deeply at BOD and cause airduct often to stop up because pressure descends again in addition.
Summary of the invention
The purpose of this utility model is: provide a kind of revolution of energy multi-segment drying to return a machine, satisfy the requirement of big air quantity when reducing air inlet place hot blast temperature, and can effectively reduce the amount of the dust granules of discharging cylindrical shell, avoid airduct to stop up.
The revolving drum machine of the utility model energy multi-segment drying comprises hot-blast stove, cylindrical shell, fan housing, airduct, air-introduced machine, chimney etc., it is characterized in that: cylindrical shell is divided into two dryer section at least, each dryer section all comprises an air inlet and an air outlet, the head end of described air inlet and air outlet one end and cylindrical shell and terminal directly be communicated with or the fan housing by the toroidal cavity structure be wrapped in fan housing in barrel wall on passage be communicated with, the other end of air inlet is communicated with hot-blast stove, and the other end of air outlet and airduct and air-introduced machine and chimney are communicated with.
The utility model adopts the technical scheme of multi-segment drying, on different material the requirement of temperature is decided, and can adopt following current and counter-current drying respectively in adjacent two dryer section, and can use same air outlet to discharge tail gas, can effectively improve drying effect, reduce equipment investment, by increasing dryer section, reduce ventilation temperature and throughput in the single dryer section, reduce the amount of the dust granules of windage and minimizing discharge, avoid stopping up airduct, the utility model barrel tip can with the revolution cooling device, roto-siofter subset tandem compound, the comprehensive function machine of formation one-machine-multi-function.
