Background technology
Present discharge refuse jigging machine; Like patent announcement number is CN87104484A " handling the particularly jigging machine of hard coal of tcrude ore "; Patent announcement number number is CN101049581A " a kind of discharge refuse jigging machine and coal preparation method thereof that independent discharge refuse road is arranged " for CN1817469A " a kind of jigging discharge refuse coal preparation method and discharge refuse jigging machine " and patent announcement; The common feature of these several kinds of discharge refuse jigging machines is bulky, and installation and maintenance take up room bigger, and version is complicated; The efficiency of separation is low, and the sorting particle size range is narrow, the difficult control of discharge refuse effect.
Summary of the invention
The objective of the invention is deficiency to existence in above-mentioned; A kind of single compass screen surface discharge refuse jigging machine that is applicable to colliery raw coal discharge refuse operation is provided, not only compact equipment, take up space little but also, transmission efficiency is high; The sorting particle size range is wide, the production good reliability.
The objective of the invention is to realize like this; Comprise cell body, discharge device, sieve plate, numerical control pneumatic air-valve, feeding mouth, discharge refuse mouth and coal outlet; It is characterized in that; Sieve plate, discharge refuse wheel, downflow weir are installed in cell body, on cell body top the numerical control pneumatic air-valve are installed, the air inlet pipe of numerical control pneumatic air-valve, blast pipe link to each other with the cell body bottom respectively.Variable-frequency motor and reductor are direct-connected structures, are connected with refuse rotor through power transmission shaft, and the direct-connected structure of variable-frequency motor and reductor is installed on the cell body outer support.The front end of cell body is provided with feeding mouth, and the rear end is provided with discharge refuse mouth and coal outlet.
Described single compass screen surface discharge refuse jigging machine, compass screen surface is along the downward-sloping installation of coal flow path direction, and the refuse rotor on the discharge device is installed in the discharge gate top of cell body.
The base surface angle of the compass screen surface of said sieve plate and installation is 8 ~ 12 °.
Described cell body is the breakdown cell body.
Described refuse rotor variable-frequency motor is installed on the cell body lateral branch board, and the refuse rotor on the discharge device is installed in the discharge gate top of cell body.
Advantage of the present invention is: compact conformation, high, the assembling convenient transportation, stable and reliable for performance of transmission efficiency, be applicable to colliery raw coal discharge refuse work, and can satisfy production requirement, help reducing the colliery operation cost, reduce ton coal energy consumption, reduce environmental pollution.Can effectively control discharging speed, guarantee stationarity, the continuity of discharge.The transmission mechanism motor and speed reducer adopts direct-connected structure, and the transmission moment of torsion is big, transmission efficiency is high.
Description of drawings:
Accompanying drawing 1 is concrete structure figure of the present invention
Accompanying drawing 2 is left views of Fig. 1
The specific embodiment:
Below in conjunction with accompanying drawing present embodiment is further specified:
Can know that by Fig. 1-2 feeding mouth 1, cell body 2, sieve plate 3, numerical control pneumatic air-valve 4, refuse rotor 5, downflow weir 6, discharge refuse mouth 7, coal outlet 8, air inlet pipe 9, blast pipe 10, variable-frequency motor 11, reductor 12 are formed.Sieve plate 3, discharge refuse wheel 5, downflow weir 6 are installed in cell body 2, on cell body 2 tops numerical control pneumatic air-valve 4 are installed, the air inlet pipe 9 of numerical control pneumatic air-valve 4, blast pipe 10 link to each other with the cell body bottom respectively.Variable-frequency motor 11 is direct-connected structures with reductor 12, is connected with refuse rotor 5 through power transmission shaft, and variable-frequency motor 11 is installed on cell body 2 outer support with reductor 12 direct-connected structures.The front end of cell body 2 is provided with feeding mouth 1, and the rear end is provided with discharge refuse mouth 7 and coal outlet 8.
Single compass screen surface discharge refuse jigging machine job step: fills with water in cell body, raw coal feeds from feeding mouth, and Compressed Gas gets into generation ascending current in the jigging machine cell body by the air inlet pipe of numerical control pneumatic air-valve, and raw coal is risen; The air inlet pipe of numerical control pneumatic air-valve is closed, and raw coal expands in cell body water, loose; The blast pipe of numerical control pneumatic air-valve is opened, and blast pipe begins exhaust, and raw coal does the interference sedimentation in cell body water, by density stratification; The blast pipe of numerical control pneumatic air-valve cuts out, and raw coal continues sedimentation, layering, implantation.Raw coal in cell body is under the effect of periodically pulsing current; Spoil and coal are by density stratification, and the spoil of big density sinks to lower floor, and the coal of little density rises to the upper strata; Spoil is discharged from the discharge refuse mouth through the discharge refuse wheel from following, and coal is crossed downflow weir and discharged from coal outlet.
