Abstract
The utility model relates to an apparatus for producing clean coal for a boiler, which is composed of a roller screen, a material collecting hopper, a dual spindle stirrer and a belt conveyer, wherein, the outer wall of the material collecting hopper is provided with a coal block rolling groove which is placed in a sloping mode, the higher end of the coal block rolling groove is communicated with the inside of the material collecting hopper, the roller screen is positioned on the upper part of the inside of the material collecting hopper and is placed in a sloping mode, and the lower end of the roller screen is communicated with the coal block rolling groove. The lower end of the material collecting hopper is provided with a flow regulating valve which is connected with a connecting point arranged on the lower end of a storage hopper in an elastic mode, the flow regulating valve is connected with the inlet of the dual spindle stirrer, and the belt conveyer is positioned on the outlet point of the dual spindle stirrer. The screening and the aggregate of coal can be proceeded together, and the utility model has the advantages of equipment reduction, energy consumption reduction and convenient operation.
Description
The utility model relates to the clean coal process units of a kind of Industrial Boiler, particularly a kind of clean coal process units that is used for the industrial chain furnace grate.
The clean coal process units of the boiler that uses in the market, the screening of coal and gather materials and be divided into separately independently two procedures, sieve and gather materials need be separately equipment, increased energy consumption, it is also very inconvenient to operate.Because raw coal has certain viscosity, can the phenomenon that coal cinder blocks aggregate bin often take place, hinder raw coal and entered next process, influenced the operate as normal of clean coal device simultaneously.Therefore pressing for that development is a kind of can be to the screening of coal with gather materials and carry out together, can effectively prevent again that coal cinder from blocking the clean coal process units of aggregate bin.Find by retrieval, do not have same or analogous product to declare patent.
The purpose of this utility model provides a kind of clean coal process units of boiler that can reach above-mentioned requirements.
To achieve these goals, the utility model is by roller screen, aggregate bin, double-shaft mixers, belt conveyor is formed, a coal cinder slot rolling is arranged on the outer wall of aggregate bin, this coal cinder slot rolling tilts to place, a higher end communicates with aggregate bin inside, its special feature is that roller screen is arranged in the top of aggregate bin, for tilting to place, a lower end communicates with the coal cinder slot rolling, the lower end of aggregate bin is equipped with a flow control valve, at flow control valve and junction, aggregate bin lower end is resilient connection, and flow control valve is connected with the inlet of double-shaft mixers, and belt conveyor is positioned at the exit of double-shaft mixers.
The clean coal process units of above-mentioned industrial boiler also is equipped with a vibrating motor on aggregate bin, be connected with an inorganic agent adding set on double-shaft mixers.
Adopt the clean coal process units of said structure, because a screening plant is installed in aggregate bin, utilize the height potential energy of coal on the aggregate bin to carry out the raw coal screening, the coal cinder separation of agitating procedure will be not suitable for entering, fall by the coal cinder slot rolling, the coal cinder that is fit to enter agitating procedure enters next procedure, makes screening and gathers materials and carry out together, has saved the consumption of the independent screening plant and the energy; Simultaneously vibrating motor is installed on aggregate bin, between aggregate bin and flow control valve, is adopted the elasticity connection, prevent raw coal in aggregate bin, guarantee carrying out smoothly of raw coal cleaning because viscosity and piling up can fall raw coal smoothly.
Below in conjunction with accompanying drawing the utility model is done a detailed explanation.
Fig. 1 is a front view of the present utility model.
Fig. 2 is a left view of the present utility model.
The utility model is made up of a roller screen 1, aggregate bin 2, a double-shaft mixers 3 and a belt conveyor 8, wherein roller screen 1 is installed in the top in the aggregate bin 2, for tilting to place, a coal cinder slot rolling 6 is arranged on the outer wall of aggregate bin, coal cinder slot rolling 6 tilts to place, roller screen 1 a lower end communicates in its higher end and the aggregate bin, and the coal cinder that is not suitable for entering agitating procedure is fallen by the position of coal cinder slot rolling guiding.For raw coal is fallen from aggregate bin smoothly, be unlikely to be bonded in the aggregate bin, a vibrating motor 5 is installed on the outer wall of aggregate bin.The lower end of aggregate bin connects a flow control valve 7, and flow control valve and aggregate bin junction are resilient connection, as connecting with rubber, falls smoothly thus to guarantee coal cinder.Flow control valve 7 links to each other with the inlet of double-shaft mixers 3, and belt conveyor 8 is installed in the exit of double-shaft mixers 3.On double-shaft mixers, also have an inorganic agent adding set 9 to be attached thereto.
During work, the coal that elder generation will prepare on workbench 4 with forklift is carried out preliminary stirring and is mixed, scoop up with forklift then and send in the aggregate bin 2, coal cinder is through the screening of roller screen 1, the coal cinder separation of agitating procedure will be not suitable for entering, fall into coal cinder slot rolling 6, and derived by the coal cinder slot rolling, all the other coal cinders enter the aggregate bin lower end.Open vibrating motor 5, the coal in the aggregate bin 2 through resilient connection part, flow control valve, falls into the groove of double-shaft mixers 3 under motor 5 vibration, and what of amount can be by flow control valve 4 controls.This moment, coal evenly was mixed, and added inorganic agent with inorganic agent adding set 9 in coal, and coal is pushed to outlet under the drive of the spirality shaft of double-shaft mixers 3, was sent to the position stacking of setting by belt conveyor 8 in the exit.The inorganic agent adding set can add water or solid sulphur, combustion adjuvant as required, by stop valve control flow, makes the coal of configuration meet burning and environmental requirement.
