Technical field

The utility model relates to a kind of crushing mechanism of material, especially a kind of counter beating hammer type disintegrator with cushioning effect.

Background technology

Hammer mill is directly to be that the material of 600-1800 millimeter is crushed to a kind of crushing mechanism below 25 millimeters or 25 millimeters with maximum particle size, is applicable at the broken medium-hard material of industrial departments such as cement, chemical industry, electric power, metallurgy.

Hammer mill mainly is made up of casing, rotating shaft, pendulum, counterattack liner plate and sieve plate etc., and charging aperture and discharging opening lay respectively at the upper and lower of casing.Hammer mill mainly is to come broken material by percussion, the motor drives rotating shaft is rotation at a high speed in crusher chamber, material is in charging aperture feeds disintegrating machine, be subjected to the impact of pendulum of high speed rotary and fragmentation, breaked material obtains kinetic energy from pendulum, and the counterattack liner plate in the high-speed impact casing, like this, material is subjected to strike, impact, shearing and the abrasive action of the pendulum of high-speed motion and pulverizes.Material less than screen size in the comminuting matter is discharged by sieve plate, and fragmentation is discharged outside the disintegrating machine by sieve plate at last greater than the material of screen size is delayed at the strike that continues to be subjected to pendulum on the sieve plate, grinding, thereby obtains the product of desired particle size.

But Po Sui material hardness is bigger if desired, and the size of material is still very big after preliminary impact of pendulum, and surpass the pendulum of hammer mill and the gap of crusher chamber, thereby can be blocked in the upper space of crusher chamber, hinder the rotation of rotor, cause work to interrupt, influence manufacturing schedule.

The utility model content

It is unobstructed that the technical problems to be solved in the utility model provides a kind of material crushing process, can not stop up, counter beating hammer type disintegrator that can discharging in small, broken bits.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of improved counter beating hammer type disintegrator, comprise casing, be separately positioned on both sides, casing top top cover and charging aperture, be arranged on the discharging opening of casing bottom, and be installed in described casing inside rotating shaft, be fixed on pendulum in the rotating shaft, be positioned at charging aperture one side and be fixed on the fixedly counterattack liner plate on the top cover and be installed in below the rotating shaft and cross section is the sieve plate of circular arc; Its key is: comprise that also at least one is installed in the activity counterattack liner plate that is provided with buffer unit of described casing inside; Described movable counterattack liner plate is between fixing counterattack liner plate and sieve plate, and its upper end is connected with casing by hinge; Described buffer unit comprises stage clip and supporting plate; Described supporting plate is connected with the lower end of movable counterattack liner plate, and described stage clip is fixed between supporting plate and the casing.

Described movable counterattack liner plate is positioned on the circle or concentrically ringed involute at sieve plate place, and the direction of its liner plate is all towards charging aperture one side.

Described disintegrating machine also comprises in order to regulate the governor motion of distance between movable counterattack liner plate and the pendulum; Described governor motion comprises adjusting screw(rod) and the baffle plate that is provided with between stage clip and supporting plate; One end of described adjusting screw(rod) is hinged with the lower end of movable counterattack liner plate, and its other end is connected with baffle plate by screwed pipe.

Adopt the beneficial effect that technique scheme produced to be: the utility model complete machine structure is simple, and is easy to operate, stable and reliable for performance.Especially movable counterattack liner plate of the present utility model has increased the dynamics that material is clashed into, can material in small, broken bits, simultaneously the bigger material of granularity can promote the buffer unit that is connected with movable lower end of strikeing back liner plate, thereby fall into the crusher chamber bottom, guaranteed that the material crushing process is unobstructed, can blockage phenomenon, the production efficiency height; Governor motion can the adjustment activity counterattack liner plate and the pendulum revolution distance between directly, thereby can pulverize the material that obtains multiple granularity.
