Accompanying drawing explanation
Fig. 1 is the structural representation of the tower-type grain drying machine of the utility model band temperature control system.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 1, the tower-type grain drying machine of described band temperature control system comprises frame 1, be installed in this frame 1 and there is the tower body 2 of the inner space for holding grain and provide thermal-radiating temperature control system 3 for the inner space of this tower body 2.
The top of described tower body 2 offers the grain-entering mouth 21 with the conducting of described inner space, and the grain outlet 22 with the conducting of described inner space is then offered in bottom.In addition, this tower body 2 has the inwall (non-label) defining described inner space, described inwall is fixed with angle-like ventilation box 23.The upper end of this angle-like ventilation box 23 has inclined-plane 231, and it is ventilated net structure, and the left end of angle-like ventilation box 23 is provided with the narrow limit 232 be connected with described inclined-plane 231, defines food passageway 24 between described narrow limit 232 and the inwall of tower body 2.In addition, the inside of this angle-like ventilation box 23 is also provided with the steam exhaust port 233 communicated with the external world; The inner space of tower body 2 is divided into the hothouse (sign) of the first half and the tempering room (sign) of the latter half by described angle-like ventilation box 23, and described hothouse is communicated with by described food passageway 24 with tempering room.
Described temperature control system 3 comprises:
Temperature sensor 31, for detecting the temperature of described tower body 2 inner space, it is inner that this temperature sensor 31 is arranged on this tower body 2, and be arranged on described angle-like ventilation box 23 top and near this angle-like ventilation box 23 place;
Electric heater 32, for radiations heat energy in described tower body 2 inner space to promote the temperature of this tower body 2 inner space;
Air blast 33, for accelerating the flowing of heat radiation in described tower body 2 inner space of described electric heater 32;
Perflation ventilation pipe 34, for the inner space guiding the heat radiation of described electric heater 32 to enter tower body 2;
Temperature controller 35, is electrically connected with described electric heater 32, air blast 33 and temperature sensor 31.
