Utility model content
For above-mentioned the deficiencies in the prior art, this utility model provides a kind of brown coal preheater and pre-heating system thereof.
A kind of brown coal preheater that this utility model provides is achieved through the following technical solutions:
A kind of brown coal preheater, it is characterized in that: include preheater shell, screw conveyor housing, rotary shaft, rotating vane is welded in described rotary shaft, described rotary shaft and rotating vane are arranged in screw conveyor housing, described rotary shaft one end is connected with driving means by reductor, described screw conveyor housing two ends are respectively provided with charging aperture and discharging opening, described preheater casing is located on screw conveyor housing, and between described charging aperture and discharging opening, described preheater outer casing inner wall and screw conveyor housing outer wall form heating chamber.
Described preheater shell two ends are respectively provided with air intake and discharge outlet, and described air intake is also hot water inlet, and being used for being passed through raw steam or condensed water, described air intake and discharge outlet is flange-interface.
Described screw conveyor housing two ends arrange the first bearing, arrange the second bearing in the middle part of described screw conveyor housing, and described second bearing passes preheater shell, and welds with preheater shell.
Described driving means is adjustable speed motor, and described buncher is arranged on motor support base, and described reductor is from setting support.
The thermal medium that adds of described heating intracavity is water vapour or hot water.
A kind of brown coal pre-heating system, including at least two aforesaid brown coal preheaters, the discharging opening of previous brown coal preheater in described multiple stage brown coal preheater connects the charging aperture of a rear brown coal preheater.
The beneficial effects of the utility model are:
1, utilize water vapour or hot water that brown coal and moisture therein are preheated, not only can preheat brown coal uniformly, and brown coal quality will not be produced harmful effect；
2, preheater shell is between charging aperture and discharging opening, decreases the number of aperture of preheater shell, easy to process, cost-effective and machining period；
3, the condensed water that First preheater is discharged can be recycled well because of water quality and is used as in boiler to supplement water, the condensed water of second preheater row can be used as domestic water, the way of recycling of both the above condensed water improves the utilization of heat energy, more energy-conserving and environment-protective, cost-effective；
4, by regulating the rotating speed of driving means, allow brown coal reach required preheating temperature, improve follow-up dewatering efficiency.
Accompanying drawing explanation
Fig. 1 is brown coal preheater structural representations；
Fig. 2 is the structural representation of brown coal pre-heating system.
Detailed description of the invention
By embodiment, technical solutions of the utility model will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those skilled in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Embodiment one
A kind of brown coal preheater as shown in Figure 1, it is characterized in that: include preheater shell 1, screw conveyor housing 2, rotary shaft 3, rotating vane is welded in described rotary shaft 3, described rotary shaft 3 and rotating vane are arranged in screw conveyor housing 2, described rotary shaft 3 one end is connected with driving means 5 by reductor 4, described screw conveyor housing 2 two ends are respectively provided with charging aperture 6 and discharging opening 7, described preheater shell 1 is set on screw conveyor housing 2, and between described charging aperture 6 and discharging opening 7, described preheater shell 1 inwall and screw conveyor housing 2 outer wall form heating chamber.
Further, described preheater shell 1 two ends are respectively provided with air intake 11 and discharge outlet 12, and described air intake 11 is also hot water inlet, and described air intake 11 and discharge outlet 12 are flange-interface.
