Description

High-effect impact crusher

The utility model relates to the technical field that a kind of high-efficiency impingement type disintegrating machine belongs to crushing mechanism.

Impact crusher is applicable to the fragmentation of fragile material, the crushing operation of materials such as the lime stone in particularly suitable cement plant and clinker, existing impact crusher, material quickens to dish out under the rotor effect in rotor channel, make the rapid wearing of passage wallboard, and the flow of rotor material feeding is also less, and efficient is on the low side.

Utilize the impact crusher of material as the counterattack wall, it is bad that it strikes back effect, is directly installed on the cylindrical wall with liner plate do counterattack device, forms a peripheral curved, improves still ideal not enough though the counterattack effect has.

Existing impact crusher, charging aperture and discharge port place dust are bigger, and base bearing temperature drift, life-span are low, demand urgently improving.

The purpose of this utility model be to provide a kind of high-efficiency impingement type disintegrating machine it can overcome above-mentioned shortcoming, air ducting can be housed reduce the dust from flying problem, add cooling device and can reduce bearing temperature, improve its life-span, adopt new counterattack device, make projected angle of impact reasonable, improve collision efficiency.

The purpose of this utility model is achieved in that cover is housed on the frame that charging aperture is positioned at its central part and puts, distributing device is arranged in the frame, the counterattack device is arranged in the frame, and rotor is contained on the main shaft, and also can there be cooling air unit and following air ducting in its below, transmission device and drive shaft revolution, the cylindrical housing that the counterattack device is made with steel plate, counterattack liner plate are inserted into above the interior bearing of housing, and the liner plate surface becomes 90 ° ± 15 ° angles with material throwing track, make collision performance better, load and unload all extremely easy.

Now in conjunction with the accompanying drawings the structure of high-efficiency impingement type disintegrating machine is described in detail.

By Fig. 1, cover (3) is housed on the frame of high-efficiency impingement type disintegrating machine (1), charging aperture (2) is positioned at the middle position of upper-cover (3), cover (3) is connected with bolt with frame (1), below in charging aperture (2), distributing device (4) is housed in the frame (1), rotor (5) is contained on the main shaft (7), counterattack device (6) is equipped with in frame (1) inside, and the below of rotor (5) is cooling device (8), and motor (10) is fixed on the motor cabinet (11), there is belt pulley (12) to link to each other with belt pulley (14) above the main shaft on the axle by belt (13), frame (1) separated into two parts is connected with bolt with flange, is convenient to the dismounting maintenance.

Fig. 2 is the schematic diagram of integral rotor structure.

Rotor (5) is a Cylinder with inner chamber (17), upper end porose (15), aperture (16) is arranged at the bottom, be provided with passage (18) in the inner chamber (17), rotor (5) is with the steel material and have anti-strict and combination of materials impact resistance and form, rotor can be provided with 3,4 or 5,6 passages, and expression has 4 passages (18) among the figure (3).

Fig. 3 is the unitary rotor cutaway view.

Rotor is when casting, and inwall is cast with vortex board (22), forms a passage (18) between the vortex board (22).

Fig. 4 is the composite fabricated rotor schematic diagram.

There was nose (24) on vortex board (22) surface when the vortex board of rotor (22) was pegged graft with inwall rib piece (23), and the triangular fin piece of rotor inner wall fluted (25), the nose (24) of vortex board (22) can be plugged in the groove (25) of rib piece (23).

Fig. 5 is a counterattack device schematic diagram.

The counterattack device is the garden cylindrical outer casing body made from steel plate (19) and hits liner plate (20) and make with the material of wear and shock-resistant, strikes back liner plate (20) and all is inserted in the bearing (21) of inner walls.Rotor (5) is contained in the middle position of counterattack device.The installation site of counterattack liner plate is to make the surface of liner plate become 90 ° ± 15 ° angles with the track of the material of being dished out, and this angle is clashed into material expeditiously, both has been convenient to install liner plate, and it is also more convenient that part is changed in dismounting.

Fig. 6 is the cooling device schematic diagram.

Bearing (26) all is equipped with at the two ends of main shaft (7), and cooling jacket (27) is housed between the bearing, and forms a cavity (28), one end water inlet flows into cooling water, and other end delivery port flows out cooling water, water circulation effect, bearing temperature is descended, prolong bearing life.

Above the frame and below the rotor, can consider to add upward air ducting and following air ducting (not shown).Last air ducting and following air ducting all are curved channel made from steel plate, because the high speed of rotor (4) rotation, make the gas-liquid in crusher chamber zone produce normal pressure, therefore the air ducting of circulation makes the interior air-flow of machine all reduce in the outside normal pressure of charging aperture and discharge port place and can reduce dust from flying so that reduce this normal pressure in adopting.

Cooling device (8) is installed in the main shaft bearing place, feeds cold water and can cool off later the main shaft bearing of rotation at a high speed, therefore can improve bearing life.

Compared with prior art, this high-effect impact crusher has following advantages.

1. the improvement of device is especially strikeed back in the improvement of structure, installs and removes all extremely easyly, increases material impact strength and bump number of times.

2. rotor structure is wear-resisting better with impact resistance.

3. bearing has cooling device, the life-span height.
