DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.

[0022] In the embodiments, a drying device for producing silicon powder is given, Figs. 1-3 The utility model discloses a drying device for producing silicon powder, which comprises a body 1, a rotating shaft 2 rotatably connected to the inner side of the body 1, a centrifugal drying cylinder 3 installed at the top end of the rotating shaft 2, a connecting shell 4 installed at the rear end of the body 1, a driving mechanism 5 arranged at the top end of the connecting shell 4 and used to drive the rotating shaft 2 to rotate, a first hinged seat 6 installed at the rear end of the body 1, a top cover 7 hingedly connected to the inner side of the first hinged seat 6, and an opening and closing mechanism 8 arranged between the top cover 7 and the body 1 and used to drive the top cover 7 to open and close.

[0023] The opening and closing mechanism 8 comprises two second hinged seats 81, two second hinged seats 81 are installed at the rear end of the body 1, and an electric push rod 82 is hingedly connected to the inner side of each second hinged seat 81. The telescopic ends of the two electric push rods 82 are hingedly connected to the rear end of the top cover 7.

[0024] Through the above arrangement, the two electric push rods 82 are retracted to drive the top cover 7 to rotate along the hinged position, so that the top cover 7 is opened. Then, an appropriate amount of raw materials is placed into the inner cavity bottom wall of the centrifugal drying cylinder 3. Then, the two electric push rods 82 are extended to make the top cover 7 rotate and close. The driving mechanism 5 is started to drive the rotating shaft 2 to rotate, and then drive the centrifugal drying cylinder 3 to rotate. In the process of rotation, the raw materials are thrown to the centrifugal drying cylinder 3 inner cavity side wall due to the centrifugal force. At this time, due to the rotation of the centrifugal drying cylinder 3, there is air flow in the inside, which can take away the moisture in the raw materials on the centrifugal drying cylinder 3 inner cavity side wall. When the raw materials are dried, they will fall back to the centrifugal drying cylinder 3 inner cavity bottom wall due to the lack of water tension. The dried silicon powder and the raw materials mixed together again will be thrown to the centrifugal drying cylinder 3 inner cavity side wall again due to the water tension. In this way, the drying of the raw materials is completed.

[0025] With reference to Figs. 1-3 The driving mechanism 5 comprises a driving motor 51, the top end of the connecting shell 4 is fixedly connected with the driving motor 51, the output end of the driving motor 51 penetrates through and extends to the inner side of the connecting shell 4, the outer side of the output end of the driving motor 51 is fixedly connected with a transmission mechanism 52, and the transmission mechanism 52 is fixedly connected to the outer side of the rotating shaft 2.

[0026] Through the structural arrangement, the driving motor 51 is started, and power is transmitted to the rotating shaft 2 through the transmission mechanism 52, thereby driving the rotating shaft 2 to rotate. It should be noted that the transmission mechanism 52 is any one of a chain wheel and chain transmission mechanism or a belt wheel transmission mechanism.

[0027] With reference to Figs. 1-3 The top end of the top cover 7 is further provided with a blowing mechanism 9, the blowing mechanism 9 comprises a blower 91, the top end of the top cover 7 is provided with the blower 91, the output end of the blower 91 is communicated with an air inlet bin 92, the air inlet bin 92 is installed at the top end of the top cover 7, the air inlet bin 92 is communicated with the machine body 1, and the machine body 1 and the bottom end of the centrifugal drying cylinder 3 are both provided with a plurality of through holes;

[0028] Through the above structural arrangement, the blower 91 sucks air into the air inlet bin 92 and into the centrifugal drying cylinder 3, and finally out of the through hole at the bottom end of the machine body 1, thereby taking away the water vaporized from the silicon powder on the cylinder wall of the centrifugal drying cylinder 3. The blower 91 makes the air flow in the machine body 1 faster, so the drying effect is better.

[0029] With reference to Figs. 1-3 The inner side of the top cover 7 is further provided with a heating mechanism 10 for heating the silicon powder;

[0030] Through the above structural arrangement, the heating mechanism 10 is internally provided with a resistance wire, which generates heat after being electrified. The heat is taken away by the gas blown by the blowing mechanism 9 and inside the centrifugal drying cylinder 3, and the silicon powder on the cylinder wall of the centrifugal drying cylinder 3 is heated, so that the water in it is evaporated and taken away by the blown gas. This can accelerate the evaporation of water in the raw materials and speed up the drying efficiency.

[0031] With reference to Figs. 1-3 The top cover 7 and the machine body 1 are further provided with a fixing mechanism 11 for fixing the top cover 7 and the machine body 1;

[0032] Through the above structural arrangement, the fixing mechanism 11, i.e. the locking device, can be used to fix the top cover 7 and the machine body 1. The locking device is any device in the prior art that can realize the fixation and release of the top cover 7 and the machine body 1, so it will not be described again.
