Description

Technical field

The invention relates to the field of mechanical engineering, namely to centrifugal units (CC) with a vertical shaft of rotation for the implementation of technological processes associated with crushing, grinding and classification of the source material.

State of the art

Famous TSU (centrifugal impact crusher) containing a loading device, a housing, an accelerating rotor, a breaker device (fender plates), a stepped bracket, a vertical support unit and an engine (US Patent No. 4699326, class. V02C 19/00, 1987). At the same time, the fender device with fender plates can be rearranged with the help of a step bracket vertically relative to the accelerating rotor as it wears out.

The disadvantage of this control unit is its short operating life, caused by the need to stop the control unit to reinstall the fender device with flue plates, in addition, the permutation is done manually after disassembling the control unit.

Of the known control units with vertically movable baffle plates, the closest in the set of essential features and the technical result achieved is the batch unit (centrifugal impact crusher), which includes a loading device, a casing, an accelerating rotor, a baffle device (baffle plates), step stops for baffle plates, vertical support unit and engine (US Patent No. 4560113, class B02C 23/00, 1985).

The disadvantage of this control unit (crusher) is its low working life, caused by the need to stop the crusher to rearrange the baffle plates, the rearrangement of the baffle plates occurs after manual disassembly of the batch plate.

SUMMARY OF THE INVENTION

The objective of the invention is to create a control center with high reliability, increased operating time without replacing the baffle plates, due to the automatic installation of baffle plates to replace worn out without stopping and disassembling the batch plate and ensuring a more complete use of the plate material.

The specified technical result is achieved in that the control unit comprises a loading device, a housing with an accelerating rotor located therein, an ancillary device, a vertical support unit, and an unloading device, while according to the invention, an ancillary device made in the form of a ring, solid or composed, is coaxially equipped with an accelerating rotor of individual elements, and at least one holder made with at least one groove, the fender device is located in the groove of the holder with a gap, while one t the chipper end is supported against the stop, and the other end of the chipper is pressed by at least one elastic element, for example, a spring placed in the groove of the holder between the end of the chipper and the bottom of the groove of the holder, the holder with the groove and the stop are fixed at least one guide paired with the groove of the holder.

The indicated constructive implementation of the fender device and the holder and their mutual arrangement with the presence of elastic elements allows to increase the productivity of the control unit by increasing the operating time before replacing the fender device and reducing the technological time for routine maintenance of the installation.

It is advisable that the holder with the groove and emphasis were made in the form of rings, solid or composed of unconnected elements. The implementation of the holder and the stop in the specified structural form allows you to install them coaxially to the accelerating rotor, and the implementation of the holder and stop from the constituent elements simplifies the manufacture and maintenance of the installation.

It is advisable that at least one through hole is made in the bottom of the groove of the holder. The presence of holes (holes) in the bottom of the groove of the holder ensures the precipitation of the crushed material from the groove and prevents jamming of the jack device when it is vertically moved inside the groove.

It is advisable that the fender device in the radial direction consist of two parts made of materials with different wear resistance, while the part of the fender plate made of a more wear-resistant material is facing the accelerating rotor. This embodiment of the fender device allows you to increase the operation of the installation without replacing the fender device or its components.

The analysis of the prior art showed that the claimed combination of essential features set forth in the claims is unknown. This allows us to conclude that it meets the criterion of "novelty."

To verify the conformity of the claimed invention with the criterion of "inventive step", an additional search was carried out for known technical solutions in order to identify features that match the distinctive features of the claimed technical solution from the prototype. It is established that the claimed technical solution does not follow explicitly from the prior art. Therefore, the claimed invention meets the criterion of "inventive step".

The invention is illustrated in the drawing and description of the design of the claimed installation.

The drawing shows an axial section of one of the possible options for the structural design of the Central Administration.

The indicated variant of the control center consists of a loading device 1, a housing 2, an accelerating rotor 3, a breaker device 4 in the form of a ring, a vertical support assembly 5, for example, in the form of a bearing assembly, holder 6, an abutment for a breaker device 7, spring elastic elements 8 located in grooves of the holder above the fender device, engine 9, holes 10 for removing crushed material. There are other possible variants of the structural design of the central assembly, for example, with a breaker device made of separate elements and from materials having different wear rates, with a lower placement of elastic elements, etc.

Information confirming the possibility of carrying out the invention

TS works as follows. The source material (for example, crushed granite) is loaded through the loading device 1 into the housing 2, then the material enters the center of the rapidly rotating rotor 3. The accelerating rotor 3 accelerates the material to high speed. The material flies out of the accelerating rotor and collapses due to impact on the fender 4. The crushed material is poured out of the unit through the hole 10. During operation, the lower part of the fender 4 is worn out, after the lower part of the plate is completely worn, it falls to the stop 7 due to gravity and springs 8. The grinding process continues further, the baffle plates periodically independently fall to the stop as they wear out until almost complete wear. The stop 7 is installed motionlessly below the zone of departure of the crushed material from the accelerating rotor, so it practically does not wear out. In addition, the emphasis can be made of a material with a high wear resistance with respect to the material from which the baffle plates are made. Based on the foregoing, we can conclude that the claimed TS can be implemented in practice with the achievement of the claimed technical result, i.e. it meets the criterion of "industrial applicability".
