The existing monocrystalline silicon powder drying equipment mainly comprises a drying cylinder, a stirrer arranged in the drying cylinder and a heater arranged on the inner wall of the drying cylinder. The monocrystalline silicon powder drying device is small in floating effect of the stirrer stirring monocrystalline silicon powder, and the heater is located on the inner wall of the drying cylinder, so that the effective contact area of the monocrystalline silicon powder and the heater is small, the heating speed is low, and the drying efficiency is low.
Disclosure of Invention
The utility model relates to a solve above-mentioned technical problem, provide a monocrystalline silicon powder drying device, its multiplicable monocrystalline silicon powder effective heating area improves monocrystalline silicon powder rate of being heated, improves monocrystalline silicon powder rate of drying.
The technical solution of the utility model is that:
monocrystalline silicon powder drying device, including a stoving section of thick bamboo, locate the inlet pipe at stoving bobbin top, locate the discharging pipe of stoving bobbin base portion, install the bleeder valve on the discharging pipe, its special character lies in: the spiral feeder is installed on one side of the drying cylinder, a feed inlet of the spiral feeder is communicated with a discharge pipe of the drying cylinder, a discharge outlet of the spiral feeder is communicated with a feed pipe of the drying cylinder, a conical cloth disc is fixedly installed below the feed pipe of the drying cylinder corresponding to the top in the drying cylinder, an air heater is fixedly installed on the side wall of the drying cylinder, and an air outlet of the air heater is led into the drying cylinder through the side wall of the drying cylinder.
Preferably, the air outlet of the air heater is tangent to the wall of the drying cylinder, and hot air blown into the drying cylinder forms spiral ascending air flow, so that the drying action time is prolonged, and the speed of discharging moisture out of the drying cylinder is accelerated.
Further preferably, the feeding hole of the screw feeder is downward inclined, so that monocrystalline silicon powder discharged by the screw feeder can rapidly enter the drying cylinder.
Further preferably, the discharge port of the screw feeder is inclined upwards, so that monocrystalline silicon powder in the drying cylinder can rapidly enter the screw feeder.
Preferably, an air outlet is arranged at the top of the drying cylinder, so that moisture in the drying cylinder can be discharged conveniently.
Further preferably, the exhaust port is covered with a filter cloth bag to prevent monocrystalline silicon powder from being discharged outside the drying cylinder.
Preferably, a connecting rod is connected between the top surface of the conical material distributing plate and the top surface of the drying cylinder.
The utility model has the advantages that:
1. because install the conical cloth dish of the inlet pipe below that the top corresponds a stoving section of thick bamboo in a stoving section of thick bamboo, install at a stoving section of thick bamboo lateral wall and let in the air heater of a stoving section of thick bamboo, the monocrystalline silicon powder falls to the bottom of the stoving tank after the conical cloth dish is fallen in the dispersion to under the hot-blast effect of air heater, with the monocrystalline silicon powder drying of dispersion whereabouts, increased the effective heated area of monocrystalline silicon powder, improved monocrystalline silicon powder rate of heating, improved monocrystalline silicon powder rate of drying.
2.
