Abstract

The utility model relate to a raw coal moisture drying conveyor which is mainly suitable for conveying raw coals used for compound combustion of a boiler. The raw coal moisture drying conveyor is mainly composed of a coal inlet bin, a material dropping opening, a raw coal conveying cavity body, a chain, a conveying chain harrow, a power wheel and a discharging opening. The characteristics of the raw coal moisture drying conveyor are as follows: the conveyor is provided with a vapor inlet pipe, a vapor outlet pipe, a vapor spray pipe, a drain valve and a safety valve, wherein the vapor spray pipe is arranged at the inner part of the raw coal conveying cavity body, the vapor inlet pipe and the vapor outlet pipe are respectively connected with the two ends of the vapor spray pipe after penetrating through the raw coal conveying cavity body, the drain valve is arranged at the bottom part of the low end of the raw coal conveying cavity body, and the safety valve is arranged at the top partof the upper end of the raw coal conveying cavity body. The conveyor can carry out moisture drying on the raw coals used for compound combustion of the boiler, so as to solve the problem that the crushing efficiency and granularity are affected due to the moisture content of the raw coals is high; compared with the prior art, the conveyor can effectively improve the combustion efficiency of the raw coals and reduce environmental pollution.

Description

A kind of raw coal moisture drying conveyer
Technical field:
The utility model relates to a kind of raw coal moisture drying conveyer, mainly is applicable to the raw coal of carrying the boiler compound combustion to use.
Background technology:
Existing boiler raw coal conveying equipment, mainly by advancing coal bunker, feed opening, raw coal is carried cavity, chain, carry chain harrow, power wheel, discharging opening is formed, wherein, advance coal bunker and connect the adjustable speed feed opening, feed opening connects raw coal and carries cavity, power wheel connects carries chain harrow, discharging opening is in the bottom of raw coal conveyor chamber height end, during work, raw coal is through advancing coal bunker, feed opening enters raw coal and carries cavity, being subjected to arriving discharging opening by the conveying chain harrow promotion of power wheel driving sends, whole process is not done any processing to raw coal, and more central moist raw coal can not be pulverized preferably and is being with more water to enter boiler combustion, must cause that combustion efficiency is bad, the thermal efficiency is low.
Summary of the invention:
The purpose of this utility model provides a kind of raw coal moisture drying conveyer, and it can overcome the deficiencies in the prior art.
The utility model is achieved in that it mainly carries cavity, chain, conveying chain harrow, power wheel, discharging opening to form by advancing coal bunker, feed opening, raw coal, it is characterized in that having steam inlet pipe, steam outlet pipe, steam jet pipe, drain valve and safety valve, wherein, steam jet pipe is in raw coal and carries inside cavity, steam inlet pipe and steam outlet pipe pass that raw coal is carried cavity and the two ends that are connected steam jet pipe respectively, drain valve is in the low side bottom that raw coal is carried cavity, and safety valve is in the top, upper end that raw coal is carried cavity.
The utility model can carry out moisture drying to the raw coal that the boiler compound combustion uses, and solves raw coal because of the high problem that influences crush efficiency and grinding particle size of water content, compared with prior art, can improve the efficiency of combustion of raw coal effectively, reduces environmental pollution.
Description of drawings:
Fig. 1 is the utility model structural representation
The specific embodiment:
As shown in Figure 1, the utility model is mainly by advancing coal bunker 1, feed opening 2, raw coal conveying cavity 3, chain 4, carrying chain harrow 5, power wheel 6, discharging opening 7 to form, it is characterized in that having steam inlet pipe 8, steam outlet pipe 9, steam jet pipe 10, drain valve 11 and safety valve 12, wherein, steam jet pipe 10 is in raw coal and carries cavity 3 inside, steam inlet pipe 8 and steam outlet pipe 9 pass that raw coal is carried cavity 3 and the two ends that are connected steam jet pipe 10 respectively, drain valve 11 is in the low side bottom that raw coal is carried cavity 3, and safety valve 12 is in the top, upper end that raw coal is carried cavity 3.
During work, steam jet pipe 3 ejection steams carry the raw coal of cavity 3 to carry out heat drying to entering raw coal, and raw coal is sent by carrying chain harrow 5 to be pushed to discharging opening 7 after being heated drying.
