Self-closed type ash and slag discharge apparatus

Abstract

The invention discloses a self-closed type ash-and-dreg discharging device which belongs to the devices for discharging the ash and dregs generated by combustion furnaces. The self-closed type ash-and-dreg discharging device is provided with a closed-type channel which is slantingly installed and connected with an ash-and-dreg discharging port, and the middle of the channel is provided with a spiral coil feeder, the rear end of which is connected with a reduction driver arranged outside the channel; the lower end of the tail part of the channel is provided with a discharging port. Since the self-closed type ash-and-dreg discharging device is provided with the simple channel and utilizes the spiral coil feeder to coil and feed material, the process of coiling and feeding upwards fully utilizes the ash and dregs per se to automatically seal air leakage of the ash and dreg discharging device and meanwhile the purpose for discharging of the ash and dregs without contaminating the surrounding air and environment is realized.

Description

technical field [0001] The invention relates to an ash and slag discharging device produced by a combustion furnace, in particular to a gas-tight self-closed ash and slag discharging device. Background technique [0002] Boilers and other furnace bodies will produce ash and slag during the combustion process. These ash and slag will fall to the bottom of the furnace through the holes of the grate, and then be removed from the holes in the bottom of the furnace manually or mechanically. However, this original ash and slag discharge method is not only unscientific, but also causes gas and flying ash pollution, etc., especially for some equipment that requires ash discharge, high sealing of the slag outlet, and no air leakage. . [0003] Retrieval of relevant materials including Chinese patents shows that there are no relevant reports on self-enclosed ash and slag discharge devices. Contents of the invention [0004] In order to overcome the gaps in the prior art, the objec...

Problems solved by technology

However, this original ash and slag discharge method is not only unscientific, but also causes gas and flying ash pollution, etc., especially for some equipment that requires ash discharge, high sealing performance of the slag outlet, and no air leakage.

[0003] Retrieval of relevant materials including Chinese patents shows that no relevant reports on self-enclosed ash and slag discharge devices have been seen so far.
