technical field

The utility model relates to the field of coal powder preparation and processing, in particular to a coal powder slag material separator.

Background technique

Coal powder is often doped with many impurities and particles. In order to meet the needs of production, it is necessary to filter the coal powder. The traditional pulverized coal preparation process often adopts a manual method when filtering small batches of pulverized coal, that is, the filter is manually operated to filter the pulverized coal. In mass production, a filtering device is also used, but the filtering device often requires additional Installation, that is, it is not integrated and automated with the production process. This kind of device not only wastes manpower and material resources, but also has low production efficiency, consumes too much man-hours, and the energy consumption of the machine is high, and the production operation is inconvenient. Therefore, there are It is necessary to provide an integrated pulverized coal filtering device combined with the production process.

Utility model content

The purpose of the utility model is to provide a coal powder and slag material separator which can filter the coal powder and slag material, and works smoothly and is integrated for the above disadvantages.

The solution adopted by the utility model to solve the technical problem is that a pulverized coal slag material separator includes a feed pipe and a discharge pipe, and a slag separation device is fixed between the feed pipe and the discharge pipe. The material separation device includes a cover plate communicated with the feed pipe, the cover plate is fixed on the slag material separation chamber, and the observation port is provided on the cover plate to communicate with the slag material separation chamber, and the cover plate is provided with The air inlet is communicated with the slag material separation chamber, and the inside of the slag material separation chamber is provided with a rotating shaft fixed on the cover plate. The circumference of the rotation shaft is covered with a shaft sleeve, and the circumference of the shaft sleeve is fixed with a separator that can rotate around the rotation shaft. The surface of the separation net is provided with a grid, and the bottom of the slag material separation chamber is provided with a cleaning tuyere for regularly cleaning the coal powder inside the slag material separation chamber, and the bottom of the slag material separation chamber is connected with the discharge pipe.

Further, the bottom of the slag separation chamber is inclined downward from the peripheral side to the discharge pipe by 15° to 40° relative to the horizontal plane.

Further, the separation net is composed of several unit fan-shaped nets, and the grids are in the shape of a honeycomb.

Further, the air inlet is located on the same side as the feed pipe.

Further, the feed pipe, the discharge pipe and the slag separation chamber are integrally cast.

Compared with the prior art, the utility model has the following beneficial effects: the pulverized coal and slag material separator is provided with a separation net inside, works smoothly, and can realize slag material separation, and the coal powder in the slag material separation chamber rotates with the separation net, Turn over, under the action of this movement, the pulverized coal and the separation net collide and rub against each other, and filter in a short time, and the pulverized coal particles of uniform size fall from the grid and enter the discharge pipe, so as to enter the next process, avoiding the occurrence of partial coal The powder size is not uniform, and even impurities and large particles appear, which improves the quality of coal powder.
