Industrial drying machine

The invention belongs to the technical field of industrial washing machinery and in particular relates to an industrial drying machine. The machine comprises a case, a door body part, an external cylinder arranged inside the case, an internal cylinder installed in the external cylinder and an air heating device installed on the case. The machine also comprises a wind guide device, wherein one endof the wind guide device is connected with the air heating device and the other end of the wind guide device stretches into the internal cylinder along the axial direction of the internal cylinder; the air heating device comprises a steam radiating box and a heat collecting cover connected with the steam radiating box; and the steam radiating box comprises a radiating primary box and a radiating secondary box which are connected with each other. The wind supply mode of the wind guide device is changed from the traditional mode of supplying wind from the radial direction to the internal cylinder to the mode of supplying wind from the axial direction, thus solving the problem of airflow shielding due to high-speed rotation of the internal cylinder during radial wind supply. As the wind is supplied from the axial direction, the airflow is sufficient and the heat loss is low, thus greatly improving the energy utilization rate, and meanwhile, the two-stage air heating mode further effectively prevents the heat energy from losing, thus lowering the use cost of the drying machine.

Part user feedback method for limited feedback of multiple-input multiple-output multi-user system

A partial user feedback method for a limiting feedback multi-input and multi-output (MIMO) multi-user system arranges different random vector codebook sets for a base station and a user terminal. Wherein, a random vector codebook set at the base station is a subset of the random codebook set for the user terminal. Based on the resultant random vector codebook set for the user, the user measures a channel vector direction. After the channel vector direction of the user is quantified and positioned into the base station, the user of the random vector codebook set is eligible to feed back. In addition, the user eligible for feedback feeds back channel gain and channel direction vector index based on the random codebook set to the base station at each time slot. Thus, the base station carries out channel re-creating to the user in light of the channel direction vector index and the channel gain fed back by the user and the random vector codebook set at the base station. In addition, the base station only selects in a set of transmission users only participating in the feed back according to the re-created user channel. The present invention can reduce feedback expense, lower complexity for the base station to select a set of transmission user, enhance system throughput rate, apply to practical systems and decrease operation cost.
