Abstract
The utility model discloses a kind of raw coal crushing and screening device, comprise inclination bar screen and oval arcuation bar screen, inclination bar screen and oval arcuation bar screen are connected to one piece, and inclination bar screen and oval arcuation bar screen outside are closed by bar screen casing, and crusher rotor is by support support rotating.Crusher rotor is equipped with breaker teeth on the surface, and the minimum range between breaker teeth with oval arcuation bar screen is equal with bar screen slot size.The utility model has saved the cost of equipment installation and raw coal washing, has saved hall space, has simplified the technique of raw coal crushing and screening.
Description
Technical field
The utility model relates to a kind of coal preparation plant raw coal crushing and screening device, is applied particularly to Raw Coal crushing and screening field, especially relates to the Crushing & Screening Machineries of raw coal between Raw Coal equipment cart.
Background technology
The effect of screening plant and breaker is for the washing of raw coal provides suitable granularity, the raw coal disintegrating machine that traditional coal preparation plant uses separates separately with screening plant, raw coal is after screening plant screening, be generally the qualified raw coal of granularity under sieve, the bulk raw coal on sieve need be crushed to suitable granularity through breaker just can enter separation system.Raw coal, after screening plant screening, sieve through transporting apparatus transports to breaker, will which not only adds production cost, also occupies larger hall space, and the complexity that technique is become.
Summary of the invention
The purpose of this utility model is to provide one makes Raw Coal crushing and screening process more simple, and production cost is lower, takies the crushing and screening device that hall space is less.
The technical solution of the utility model is: a kind of raw coal crushing and screening device, comprise inclination bar screen, the oval arcuation bar screen be connected with inclination bar screen, the casing of inclination bar screen and oval arcuation bar screen, crusher rotor above oval arcuation bar screen, for supporting the support of crusher rotor, the casing of disintegrating machine outside seal.
The beneficial effects of the utility model: crushing and screening device described in the utility model has saved the cost of equipment installation and raw coal washing, has saved hall space, has simplified the technique of raw coal crushing and screening.
Accompanying drawing explanation
Fig. 1 is the sectional view that the utility model simplifies.
Fig. 2 is the structural representation of inclination bar screen of the present utility model and oval arcuation bar screen.
Drawing illustrates: 1. inclination bar screen; 2. oval arcuation bar screen; 3. crusher rotor; 4. breaker teeth; 5. disintegrating machine casing; 6. support; 7. bar screen casing.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but be not restriction the utility model.
See accompanying drawing, a kind of raw coal crushing and screening of the utility model device, comprise inclination bar screen 1 and oval arcuation bar screen 2, inclination bar screen 1 and oval arcuation bar screen 2 are connected to one piece, inclination bar screen 1 is identical with the sieve aperture of oval arcuation bar screen 2, is closed by bar screen casing 7 at inclination bar screen 1 and oval arcuation bar screen 2 outside.Crusher rotor 3, above oval arcuation bar screen 2, is supported by support 6, and runs together with unshowned conventional actuator and namely rotate.Crusher rotor 3 is equipped with breaker teeth 4 on the surface, and the minimum range between breaker teeth 4 with oval arcuation bar screen 2 is equal with bar screen slot size.Crusher rotor 3 outside is closed by disintegrating machine casing 5.During device work, raw coal is fallen on inclination bar screen 1, the particle that in raw coal, granularity is less than screen size becomes through the compass screen surface of inclination bar screen 1 undersize meeting sorting and require, particle on sieve enters on the sieve of oval arcuation bar screen 2 along the compass screen surface of inclination bar screen 1, crusher rotor 3 rotates along the direction shown in arrow, breaker teeth 4 cooperates mutually with oval arcuation bar screen 2, the raw coal of bulk is broken between breaker teeth 4 and oval arcuation bar screen 2 compass screen surface, and becomes through oval arcuation bar screen 2 undersize meeting sorting requirement.
