Stokehole coal pulverization device

Abstract

The invention discloses a stokehole coal pulverization device. The device structurally comprises a powder outlet, a grinding pulverization mechanism, a control main engine, a regulator, a hopper and an iron material gate. According to the improved pulverization device, coal particles are grinded through a grinding roll, the gap between the grinding roll and a grinding seat is gradually decreased,and the grinding fineness is gradually improved, so that the coal grinding quality is ensured; the grinded coal falls on a filter screen, and a first motor drives the filter screen to vibrate, so as to vibrate and screen the coal particles; when coal particles which are small enough slide between the grinding seat and a second grinding roll, a third motor is started, the third motor rotates to ensure that a rack moves leftwards and rightwards and the second grinding roll rotates forwards and backwards so as to grind the coal particles; and the grinded coal slides rightwards from a material sliding plate and then slides out through a discharging groove, so that the coal is sufficiently grinded and the grinding efficiency and effect are improved.

Description

technical field [0001] The invention relates to a pulverizing device in front of a coal furnace, which belongs to the field of pulverizing devices in front of a coal furnace. Background technique [0002] Coal pulverizing in the general sense is actually a kind of coal pulverization and crushing process, which belongs to the primary stage of coal pulverizing. The particle size requirements for fine pulverized coal; and most of them are open-type operation, and the dust pollution is relatively serious. However, in the process of pulverizing the existing coal, the fine metals such as iron in the coal often affect the operation of the grinding equipment or cause production stoppage, etc., which hinders the pulverizing operation of the coal and makes it difficult to guarantee the grinding effect. SUMMARY OF THE INVENTION [0003] In view of this, the embodiment of the present invention provides a coal pulverizing device in front of the furnace, so as to improve the existing c...
