Abstract
The invention belongs to the technical field of hammer type mills and particularly discloses an impact crusher. The impact crusher comprises a crushing box with a discharge port, rotors arranged in the crushing box and plate hammers installed on the rotors. The impact crusher further comprises baffles. Feed ports are formed by the baffles and the side walls of the crushing box. The two feed ports correspond to the two rotors. The rotors are located below the feed ports and rotate oppositely. Due to the fact that the two rotors rotate oppositely, aggregated rock collides in the box after being preliminarily crushed in the two feed ports, and the crushing effect of the aggregated rock is better through great collision force. Meanwhile, due to the fact that the two feed ports simultaneously conduct feeding, the crushing efficiency is higher.
Description
Technical field
The invention belongs to hammer mills technical field, particularly relate to a kind of impact breaker.
Background technology
Impact breaker is a kind of building stones disintegrating apparatus, it generally includes broken case, be placed in the rotor of broken case inside, be arranged on epitrochanterian bar, the parts such as impact rack and counterpunch board be arranged in inner walls, it utilizes the epitrochanterian bar of High Rotation Speed broken to the building stones generation high speed impact sent in broken case, and make broken building stones along the tangential direction by bar strike place to throw at a high speed the counterpunch board of the broken case other end, again strongly clashed into fragmentation, then from counterpunch board rebound bar continue repeat said process.Existing impact breaker only has a charging aperture usually, and each charging is limited, and crushing efficiency is low.
Summary of the invention
Object of the present invention is providing the impact breaker that a kind of crushing efficiency is high.
In order to achieve the above object, the invention provides a kind of impact breaker, comprise the broken case being provided with discharging opening, the rotor being arranged on broken case inside and be arranged on epitrochanterian bar, wherein, also comprise baffle plate, the sidewall of described baffle plate and broken case forms charging aperture, the quantity of described charging aperture and rotor is two, rotor is corresponding with charging aperture to be arranged, and rotor is positioned at the below of charging aperture, and described rotor rotates in opposite directions.
Unimach as herein described refers to that yield strength is at 1 370MPa(140 kgf/mm2) more than, tensile strength is at 1 620 MPa(165 kgf/mm2) more than steel alloy.Current protector and the excessive protector of electric current, be a kind of can accurately control apparatus because the protection element of the excessive generation temperature overheating of electric current.
Principle of the present invention and beneficial effect are: building stones enter broken case respectively in two charging apertures, when the rotor contact of building stones and High Rotation Speed, epitrochanterian bar is broken to the building stones generation high speed impact sent in broken case, and makes broken building stones along the tangential direction by bar strike place to throw at a high speed the other end of broken case.Because two rotors rotate in opposite directions, building stones are by middle collision in case after preliminary fragmentation from two charging apertures, and huge impact force makes the better effects if of building stones fragmentation.Meanwhile, owing to being the chargings simultaneously of two charging apertures, crushing efficiency is higher.
Further, described baffle plate is unimach, and described baffle plate is unimach.Building stones often can be thrown on baffle plate, also can be broken after building stones collision overhead gage.The impact strength of the baffle plate of unimach is good, and service life is higher.
Further, the output shaft of described motor is connected on rotor.By motor powered rotor, relative to manual operation, efficiency is higher, more laborsaving.
Further, motor is servomotor, and servomotor can control rotating speed accurately, and impact breaker is more easily controlled.
Further, described motor is provided with rotation-clogging protection device.Because building stones in broken case are many, easily stuck, cause motor rotation blockage, rotation-clogging protection device well can protect motor, improves the service life of motor.
Accompanying drawing explanation
Fig. 1 is the structural representation of impact breaker embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: broken case 1, rotor 2, bar 3, the first baffle plate 4, second baffle 5.
As shown in Figure 1, a kind of building stones disintegrating apparatus, comprise the broken case 1 being provided with discharging opening, be arranged on the rotor 2 of broken case 1 inside, be welded on epitrochanterian bar 3, first baffle plate 4 and second baffle 5, first baffle plate 4 is welded on the inside of broken case 1, and form the first charging aperture with the right side wall of broken case 1, second baffle 5 is also welded on the inside of broken case 1, and form the second charging aperture with the left side wall of broken case 1, the quantity of rotor 2 is two, lay respectively at the below of the first charging aperture and the second charging aperture, rotor 2 is connected with the output shaft of servomotor, rotate in opposite directions between rotor 2, servomotor being also provided with model is VJ-802(1 ~ 30A) be rotation-clogging protection device.
During specific works, building stones enter broken case 1 respectively in two charging apertures, and when building stones contact with the rotor 2 of High Rotation Speed, epitrochanterian bar 3 is broken to the building stones generation high speed impact sent in broken case 1.The right side of broken case 1 is thrown in left side with high speed by the tangential direction of bar 3 strike place through the building stones edge of fragmentation, the left side of broken case 1 is thrown on right side with high speed by the tangential direction of bar 3 strike place through the building stones edge of fragmentation, the building stones of the left and right sides then collide in broken case 1, and the huge impact force of generation makes the better effects if of building stones fragmentation.Meanwhile, owing to being the chargings simultaneously of two charging apertures, crushing efficiency is higher.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
