Detailed Description

As shown in fig. 1 and 2, an improved mechanical impact crusher comprises a housing 1, a rotating disc 2 rotatably mounted in the middle of the housing 1, a main shaft 10 rotatably mounted in the housing, and a power device 9 fixedly mounted on the main shaft 10 for driving the main shaft to rotate, wherein the power device 9 may be an electric motor or the like. Be equipped with on the casing 1 and be located the air intake 3 of 2 below rolling discs, the upper surface of rolling discs 2 is equipped with crushing head 4, still be equipped with in the casing 1 and be located the hierarchical mechanism of 2 tops of rolling discs, hierarchical mechanism includes hierarchical wheel 18, hierarchical mechanism's structure is unanimous with prior art, if can adopt the structure disclosed in the CN202377193U, the inner wall of casing 1 be equipped with crushing head 4 complex smashes welt 5, still be equipped with in the casing 1 and be located rolling discs 2 with water conservancy diversion casing 6 between the hierarchical mechanism, install inlet pipe 7 on the casing 1, the inner of inlet pipe 7 penetrates 1 inner chamber of casing and entering in the water conservancy diversion casing 6, the lower part of water conservancy diversion casing 6 is equipped with and is located the discharge gate 8 of 2 tops of rolling discs. The shell is also provided with a slag outlet 19 positioned below the rotating disc.

The discharge hole is over against the rotation center of the rotating disc.

The arrangement of the diversion shell 6 increases the flow velocity of the air flow, so that the materials are clearly layered in the grading zone; the lower part of the diversion shell 6 is provided with a discharge hole 8 positioned above the rotating disc 2, so that the intermediate feeding is realized, the material entering the crushing chamber directly enters the crushing area without colliding with the crushed material, the energy consumption is reduced, and the production capacity is improved; because the grading device is installed at the top of the mechanical impact crusher, a product with a good grading effect can be obtained, and meanwhile, the grading device is connected with the draught fan, so that negative pressure is generated in the crusher, no dust is leaked, and the operation environment is protected. The discharge fineness and the grading precision are improved, the energy consumption is reduced, and the production capacity is improved.

The discharge hole is provided with a discharge hole cover 11. The discharge port cover can be closed when the discharging is not carried out.

The lower surface of the rotating disc 2 is an inverted conical surface 13.

The water conservancy diversion casing includes cylindrical barrel 14, right circular truncated cone shape casing 15 is installed to cylindrical barrel 14's upper end, reverse circular truncated cone shape casing 16 is installed to cylindrical barrel 14's lower extreme.

As shown in fig. 3, a projection 17 is fixedly mounted on the outer peripheral surface of the reverse truncated cone-shaped housing 16. The protrusion is favorable for blocking large-particle materials from moving upwards, so that the large-particle materials can fall on the rotating disc and continue to be crushed under the action of the crushing head 4.

As shown in fig. 2, the discharge port cover 11 is hinged on the lower surface of the inverted circular truncated cone shaped casing 14, and a torsion spring is arranged between the discharge port cover 11 and the diversion casing 6 to make the discharge port cover 11 attached on the lower surface of the inverted circular truncated cone shaped casing 16. When the inlet pipe had the material to discharge from the discharge gate, the gravity of material promoted the discharge gate lid downwards and opened, when there was not the material to discharge from the discharge gate lid is closed under the effect of torsional spring to realized the automatic on-off control of discharge gate lid, avoided the material to get into wantonly the refluence casing.

The material enters the crushing chamber through the feed pipe 7 and falls to the center of the rotating disc 2. The main shaft 10 drives the rotating disc 2 to rotate at a high speed through the power device 9, the rotating speed can reach 2960r/min due to the control of the variable frequency speed regulating system, and the linear speed of the outer ring of the rotating disc 2 can reach 118m/s. Due to the centrifugal effect caused by the high-speed rotation of the rotating disc 2, the materials are thrown to the working area of the crushing head 4 at a high speed, are impacted, rubbed and sheared to be crushed under the action of high-speed air flow, the crushed materials are reflected to the lining plate 5, the materials reflected back along the lining plate 5 also enter the working area of the crushing head 4 again to be crushed, the fine crushing degree of the materials is improved through the circular crushing process, and the medium-hardness materials with the finished product fineness of D97=2-3um can be produced. The micro powder is lifted to a grading area under the action of ascending airflow through an overflow channel between the outer edge of the guide shell 6 and the shell 1, different air centrifugal forces are generated due to different rotating speeds of the grading wheels 18, the materials with qualified fineness are discharged out of a discharge hole through a labyrinth and then collected by a dust collector, purified gas is discharged by a draught fan, coarse powder is sent back again under the action of gravity and other impact energy, and the working area of the rotating disc 2 is crushed for multiple times. Impurities, waste materials which cannot be crushed and part of micro powder enter the lower part of the rotating disc 2, compressed air enters from the air inlet 3 and sends the micro powder back to the working area of the rotating disc 2, and the impurities and the waste materials which cannot be crushed are accumulated at the sunken slag outlet 19 and are discharged.

The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitution or transformation made by the technical personnel in the technical field on the basis of the utility model is within the protection scope of the utility model.
