Description
Technical field
The utility model relate to a kind of in ature of coal, the coke etc., that the soft material carries out coarse crushing, screening and fine crushing is multi-functional in the crushing and screening integral device of one.
Background technology
Existing disintegrating machine has various ways such as discaling roll, arc screening plate or counterattack dental lamina respectively in its crusher chamber.When work material directly enter on the feeding mouth of crusher chamber, material not of uniform size falls together, is broken together, by after the fragmentation step by step, material is discharged from discharging opening.But the problem that existing disintegrating machine exists is:
1, material is an all-in and all-out, causes the disintegrating machine load to increase, the wearing and tearing aggravation, and it is serious that material is crossed broken phenomenon.
Even 2 are provided with screening plant, but in the prior art, normally screening plant and disintegrating apparatus are separately positioned on different places, cause capital expenditure big, system layout is loaded down with trivial details.
3, be mingled with under the bigger situation of tiny material and continuous flow when bulk materials, tiny material can not in time be discharged and can be produced jam by crusher chamber, and when the humidity of material was big, a large amount of wet stocks can stick in the crusher chamber, also can produce jam.
As Granted publication number is CN201168637Y, Granted publication day is the Chinese patent file in December 24 in 2008, a kind of elementary screening plant of disintegrating machine is disclosed, comprise frame, described frame is provided with the primary dcreening operation chamber, primary dcreening operation chamber top and bottom ends has respectively into, discharging opening, in the feeding mouth of primary dcreening operation chamber, be provided with the conveying sieve roller of a plurality of rotating throughput directions side by side towards the edge of primary dcreening operation chamber one side, but be provided with the gap that the long-pending qualified material piece of donor passes through between each adjacent conveyor sieve roller, each carry sieve roller by transmission mechanism by the drive mechanism that is fixed on the frame.This utility model is with the supporting use of disintegrating machine the time, most of satisfactory material piece can directly leak down from the gap between the adjacent conveyor sieve roller and fall into discharging opening, the material that remaining volume is bigger is admitted to crushing chamber soon and carries out fragmentation under the drive of the conveying sieve roller that rotates, because material has carried out elementary screening in the primary dcreening operation chamber and with material diversion, can effectively reduce the jam that existing disintegrating machine exists, improve the breaking capacity of disintegrating machine complete machine.
But technique scheme is when broken material, and when once big material being crushed to satisfactory tiny material particular diameter, the ratio of reduction is too big, and disintegrating machine is difficult to big material primary fragmentation to satisfactory tiny material.Thereby cause material particular diameter to exceed standard, do not reach instructions for use.And crushing teeth plate structure complexity, overhaul difficult expense height.
The utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of in ature of coal, the coke etc., the soft material carries out coarse crushing, sieves and has the crushing and screening integral device of fine crushing function, adopt the utility model, when coarse crushing, after being broken, material can enter screening plant by grating smoothly, when the screening material, material can not produce jam by screening plant, screening percentage is high, and the cloth effect arranged, oversize enters fine crusher and is crushed to satisfactory particle diameter step by step, has guaranteed the granularity requirements after the material fragmentation.
The utility model is realized by adopting following technical proposals:
A kind of crushing and screening integral device, comprise frame, it is characterized in that: in frame, be respectively arranged with first order breaker, screening plant and second level breaker, described first order breaker comprises first order broken rotor and is used to sieve the sieve of broken back material, first order broken rotor and sieve form first order crusher chamber, described screening plant comprises a plurality of sieve rollers that are used for convey materials that are arranged side by side, the surface of a plurality of sieve rollers forms the compass screen surface that material is sieved, gap between any two rollers forms sieve aperture, the conveying arrival end of screening plant connects described sieve, and the conveying port of export of screening plant connects described second level breaker.
Described second level breaker comprises second level broken rotor, broken discaling roll and counterpunch board, described counterpunch board is positioned at the top of second level broken rotor, broken discaling roll is installed in a side of second level broken rotor, broken discaling roll is more than 2, be meshing with each other between each broken discaling roll, second level broken rotor, counterpunch board and crushing teeth roller form second level crusher chamber.
Described first order breaker is thick broken device, and second level breaker is thin broken device.
The annular surface of described sieve roller is provided with the sieve tooth, and the sieve backlash between any two sieve rollers forms sieve aperture.
Described compass screen surface is from that near end height of first order breaker outlet, from the near low inclined ramp shape of that end of second level breaker inlet.
Described sieve is made up of a plurality of gratings that are arranged in parallel, and the gap between the grating forms the sieve aperture of material.
Described sieve is a sieve-plate structure, and sieve plate is provided with sieve aperture.
Described sieve roller is sieve ring roller or screen drum roller.
On described first order broken rotor and second level broken rotor, be provided with the tup that impacts material.
Described counterpunch board is fixed on the frame through spring.
Described sieve is fixed on the frame through support.
Described broken discaling roll is replaced with grating.
Compared with prior art, the beneficial effects of the utility model show:
1, because the utility model adopts below first order breaker, be provided with screening plant, a plurality of sieve rollers rotate under the drive of rotating machinery in the same way, material is carried out forced conveyance, force screening, and has certain fragmentation, thereby can not produce jam, more excellent, the sieve roller is provided with the sieve tooth, any two gaps of sieve between the teeth form sieve aperture, and the material that meets granularity requirements is sifted out from sieve aperture, make to be sized material more unobstructed operation on compass screen surface, fall by mesh screen smoothly, it is broken in advance to utilize first order crusher chamber that material is carried out, and makes follow-up equipment when work the more even material that does not have bulk can be arranged, and can play good cloth effect simultaneously again.
2, the utility model adopts in screening and carries discharge port end that second level breaker is set, broken discaling roll is more than 2, conveniently the oversize that does not meet granularity requirements is carried out broken step by step, and, the material that meets granularity requirements sifts out from sieve aperture, alleviate the live load of second level breaker, prolonged the service life of second level breaker, reduced the broken phenomenon of mistake of material.
