Description

FIELD OF THE INVENTION

The invention relates to grinding technology and can be used in animal feed, flour, food, medical, chemical and mining industries.

State of the art

A cone inertial crusher is known, which includes a housing with an outer cone and a spherical support for the inner cone with a shaft bearing an unbalance bearing bush connected to the drive pulley by means of a support ball spindle, an intermediate shaft located in the bearings of the housing, and a flap clutch (see ed. St. SU No. 632388, IPC B02C 2/04, 1975).

The disadvantages include a large technological height, significant metal consumption and structural complexity due to the presence of a support-drive spindle, which limits the widespread distribution of crushers in industry. In addition, the elastic support of the housing on the foundation reduces the crushing efficiency (productivity and degree of crushing).

Known crusher containing a frame with an outer cone, placed in the last inner cone, coupled by means of a spherical bearing with a blind sleeve with imbalance mounted on a vertical shaft kinematically connected with the electric drive, discharge pipe (see ed. No. 1404106, IPC B02C 2 / 02, 1988).

The main disadvantage of this crusher is that the inner cone rests only on a spherical bearing, which does not create additional elastic force, reinforcing the destructive dynamic force of the inner cone, which reduces the grinding efficiency.

The closest in technical essence to the present invention is a cone inertial crusher containing a housing with an outer cone and an inner cone having a shaft with an unbalanced vibrator placed on it, the drive element of which is made in the form of a balancing crusher leading counterbalance with end side surfaces in contact with mating surfaces unbalanced vibrator, and in the center of the base of the housing there is a cylindrical vertical support element, on which the bearings are mounted A leading counterbalance with a concentric part made in the form of a driven pulley of a V-belt drive transmission has been installed (see patent RU No. 2097132, IPC B02C 2/02, 1997).

The disadvantages of such a cone inertial crusher include the low efficiency of crushing the material, as it is designed for crushing solid materials, which eliminates the achievement of high uniformity of grinding material, especially wet. And also the cone has a smooth surface, which does not provide for the forced transportation of material.

Disclosure of invention

The technical result that can be achieved using the present invention is to increase the reliability in operation, the efficiency of the crushing process, the management of the crushing process.

The technical result is achieved using an inertial cone crusher comprising a housing with an outer cone and an inner cone having a shaft mounted on two bearings, moreover, it is additionally equipped with a metering plate, a regulating plate and adjusting screws, the inner cone mounted on the shaft made with the possibility of interchangeability, has a right winding in the form of a triangular thread, and the outer cone has a left winding in the form of a triangular thread, while the outer cone has a safety stopper.

The implementation of the invention

The inertial cone crusher (Fig. 1) contains a housing 2 rigidly mounted on the support frame 1 with an outer cone 3 with a left winding 4, a safety stop 5, an inner cone 6 with a right winding 7, a coupling screw 8, a shaft 9 with a driven pulley 10, bearings 11, the metering plate 12 with the technological hole 13, the regulating plate 14 with the technological hole 15, the adjusting screws 16, the window 17 for the V-belt 18, the drive pulley 19 of the electric motor 20.

A safety stop 5 fixes and protects the outer cone 3 from the housing 2 from self-unscrewing. On the outer cone 3, the left winding 4 is made in the form of a triangular thread, which provides cutting with sliding of the crushed material, which increases the productivity of the crusher and reduces energy costs. The inner cone 6 with the right-hand winding 7 made on it in the form of a triangular thread using the clamping screws 8, which are necessary to ensure the possibility of interchangeability when it is worn or broken, is mounted on the upper end of the shaft 9, which has a driven pulley 10 at the other end and is installed together with bearings 11 in the housing 2, equipped with a metering plate 12 with a technological hole 13 (FIG. 2), a regulating plate 14 with a technological hole 15 (FIG. 3) and adjusting screws 16 that allow the plates 12 and 14 to be fixed to each other in a position about espechivayuschem predetermined overlap technological holes 13 and 15 for the required degree of grinding material which wakes up through these openings. In the housing 2, windows 17 are made for the V-belt 18, the branches of which pass through the windows 17 of the housing 2 and enter the drive pulley 19 of the electric motor 20.

Inertial cone crusher operates as follows.

The material to be crushed is loaded from above between the inner 6 and outer 3 cones, the latter being fixed by a safety stop 5. The rotation from the electric motor 20 and the drive pulley 19 by the V-belt 18 passing through the windows 17 of the housing 2 is transmitted to the driven pulley 10, which drives rotation of the shaft 9, rotating in the bearings 11 in the housing 2. The centrifugal force of the shaft 9 through the clamping screws 8 causes the inner cone 6 to make movements and grind the material located between the cones 3 and 6, while the right winding 7 in the form of triangles The coiled thread on the inner cone 6 and the left winding 4 in the form of a triangular thread on the outer cone 3 create oncoming flows of the crushed material, which leads to its cutting with sliding with less energy. Next, the crushed material, having reached a certain fraction, wakes up through the technological holes 13 and 15 of the metering plate 12 and the control plate 16, which are fixed with the adjusting screws 16 in a position specified by the degree of grinding of the material.

The invention in comparison with the prototype and other known technical solutions has the following advantages:

- increases the reliability of the crusher;

- increases the efficiency of grinding material;

- provides the ability to grind wet and viscous plastic materials;

- provides control of the process of crushing material;

- provides the ability to replace the working grinding body.
