technical field

The present invention relates to the drying field of coal slime, in particular to an energy-saving and environment-friendly slime dryer and a method for using the same.

Background technique

Coal slime is a by-product produced during the coal washing process in coal preparation plants. It has the characteristics of high water content, high viscosity and high water holding capacity, so it is difficult to achieve industrial application. Most of them are used for coal slime boiler combustion and power generation. In order to prevent the slime from bringing too much water into the boiler, it is necessary to dry the slime first, and then the dried slime will enter the boiler together with other raw coal for combustion, which improves the production efficiency.

9. a kind of application method of energy saving and environment friendly coal slime drying machine, which comprises the following steps:

One, by coal slime to be dried out of feeding mechanism (5) after investment, the cover board (53) closed on feeding mechanism (5) and go out Expect the bottom cover (82) on mechanism (8), hot wind is then passed through out of connecting tube (42), then driving two servo motors (23) makes simultaneously Roller (1) realizes rotation；

Two, it after the completion of to be dried, closes servo motor (23), so that discharge nozzle when roller (1) is shut down on discharging mechanism (8) (81) bottom end downward, at this point, the material in roller (1) has dried completion；

Three, the bottom cover (82) on discharging mechanism (8) is opened, drives swing handle while rotating the second limit plate (64) (8304), so that the second sieve plate (86) is to bottom offset, it is located at material at spiral drainage paddle (62) from the in discharging mechanism (8) It is expelled directly out in two sieve plates (86), the material between ram (12) is mobile to roller (1) one end in the effect of gravity, moves Dynamic material falls into the then discharge out of the second sieve plate (86) in discharging mechanism (8), and a small number of biggish feed blockings are in the second sieve On plate (86), the material being now placed between ram (12) is not completely exhausted out；

Four, swing handle (8304) are driven, the material being blocked on the second sieve plate (86) is driven up to spiral and drains paddle (62) it can be drained to one end of ram (12), the material for being located at ram (12) other end moves under the effect of gravity Until falling into the then discharge out of the second sieve plate (86) in discharging mechanism (8), a small number of biggish feed blockings are in the second sieve plate (86) on, repeatedly, until lesser material is completely exhausted out, biggish material, which leaves, continues breaing up and doing next time It is dry.
