A kind of swing type contracting device
Technical field
The present invention relates to coal sample making technology field, more particularly to a kind of swing type contracting device.
Background technology
With the development of power construction cause, coal-burning power plant constantly goes into operation and run, and its operation and management level also carries therewith
Height, ature of coal sample detecting workload increase, and mechanical sampling equipment progressively instead of artificial sample, and its complexity is also increasingly
Height, multistage sampling is developed into by initial single-stage sampling.In mechanical sampling sample preparation, division is the key procedure of sample preparation, mesh
Be reduce sample size.Contracting device is primarily used for coal or prepared by the division of other granule materials samples.
The coal dust contracting device overwhelming majority in the market utilizes the structure of centrifugal force division.It is mainly by division cavity
13rd, belt 14, driving pulley 15, passive belt wheel 16, be rotated into hopper 17, the bearing collar 18, deep groove ball bearing 19, motor and fix
Chute 24, support plate 25, upper side stay under chute 23, the second division under plate 20, reducing motor 21, division baffle plate 22, the first division
Plate 26 and downside fagging 27 are formed.
As depicted in figs. 1 and 2, reducing motor 21 is arranged on motor fixing plate 20, and driving pulley 15 is inserted into motor shaft
Middle fixation, then be connected by belt 14 with passive belt wheel 16.Passive belt wheel 16 is fixedly linked with being rotated into hopper 17, passive belt wheel
16 are arranged on the bearing collar 18, and are supported on by deep groove ball bearing 19 on support plate 25.Support plate 25 is arranged on division chamber
The upper end of body 13.Division baffle plate 22 is arranged under the first division under the division of chute 23 and second by the coal feed point of chute 24, to adjust
Whole coal dust division amount.Finally fixed entirely through upside fagging 26 and downside fagging 37.
The operation principle of the contracting device is:Reducing motor 21 drives driving pulley 15 to rotate, and driving pulley 15 recycles skin
Band 14 drives passive belt wheel 16 to rotate, and then the hopper 17 that is rotated into for making to be fixed on passive belt wheel 16 rotates together with.Coal dust enters
Enter to be rotated into hopper 17, there is certain centrifugal force by rotary motion, outwards shed in exit.When being rotated into hopper 17
Outlet is rotated under the first division under the division of chute 23 and second during the coal powder entrance of chute 24, and a certain amount of coal dust is shed entrance
Under first division under the division of chute 23 and second in chute 24, reach the purpose of division.Adjustment division baffle plate 22 blocks the first contracting
The coal powder entrance size of chute 24 adjusts division amount under point lower division of chute 23 and second.
Due to centrifugal action, coal dust is patted in division cavity, makes substantial amounts of residual coal dust in cavity be present, with
The progress of coal dust is detected, the coal dust accumulation of residual increases, and the coal dust of detection easily produces with residual coal dust to be mixed, and data are forbidden
Really, meanwhile, after rotary speed is too high, detected coal dust can lose moisture.
