Solid scattered material discharging controlling device

Abstract

The invention relates to a solid scattered material discharging controlling device. The device comprises a feeding hopper, a scattered material driving device and a discharging controlling device housing. The feeding hopper is externally provided with a vibrator, and a conical guiding hood is arranged in the feeding hopper. The discharging controlling device housing is mainly composed of a scattered material conveying pipe and a scattered material feeding passage which is arranged on the top of the housing, the scattered material conveying pipe is composed of two circular pipes with the same diameter, and the scattered feeding passage is composed of two rectangular pipes. The feeding hopper and the scattered material feeding passage are connected and fixed by a soft connecting flange and ashock-absorbing device. The scattered material driving device is provided with spiral blades and a driving motor, and two groups of the spiral blades are fixed in the scattered material conveying pipe. The device has the advantages that the scattered material in the upper portion of the discharging device can flow approximately as a whole without obvious material flowing deflecting, blocking andnonuniform speed distribution, the device can be operated at a higher temperature, and therefore the continuous and stable movement of the scattered material at a lower flow rate is achieved.

Description

technical field [0001] The invention relates to a solid bulk material discharge control device, which is mainly aimed at controlling the flow of bulk material within a certain particle size range, especially powder, and is mainly used for high-temperature bulk material heat exchangers. The device can realize bulk material at a lower temperature Continuous and stable motion at flow rates. Background technique [0002] In the production process of metallurgy, building materials and other industries, a large amount of high-temperature bulk or powdery bulk materials will be produced. The cooling methods of these bulk materials are mainly divided into direct heat exchange and indirect heat exchange. The heat surface is isolated to avoid problems such as dust removal, bulk material or heat exchange medium pollution, and the application prospect is broader. The indirect heat exchange methods mainly include tube-row heat exchangers and plate heat exchangers. The bulk material fills...
