Description

Cantilever type ultrafine pulverizer

technical field

The utility model relates to an ultrafine pulverizer, in particular to a double-rotor impact ultrafine pulverizer with a cantilever support structure.

Background technique

In cement, mining, chemical industry, metallurgy, road construction and other industries, it is an important production link to carry out ultrafine crushing of brittle massive materials, such as ore, cement clinker, lump coal, etc. At present, the ultra-fine pulverization of these brittle block materials is to use a roller press or a column mill. Due to the hard contact, the rollers and grating plates wear very fast, and the gap adjustment and the surfacing welding of the rollers and the grating plates must be carried out frequently, and the unit power consumption and maintenance costs are large. The purchase investment is huge, about 20 times that of the cantilever type ultrafine grinder.

Patent No. ZL200420017744.6 discloses a double-rotor crusher with internal screening. An outer rotor and an inner rotor are installed in the upper cavity of the frame. Transmission mechanism connection. The disadvantage is that the structure is complex, and the transmission mechanism of the inner rotor is on the top of the machine body, which makes the overall size of the machine too large, which is not conducive to the transformation in the old factory building. At the same time, the lower part of the rotating shaft of the inner rotor hangs in the air, and when the machine is running at high speed, the swing is relatively large. It has a certain influence on the stable operation of the machine.

Patent No. 200620097633.X discloses a frame pre-grinder, which adopts a stable frame structure and overcomes the shortcomings of ZL200420017744.6. However, in practical application, it is found that the frame type pre-grinding machine has the disadvantages of complex structure, which is not conducive to installation and maintenance.

The cantilever ultrafine pulverizer overcomes the shortcomings of the above two forms.

Contents of the invention

The purpose of the utility model is to provide a cantilever type superfine pulverizer which is stable and reliable, saves investment, increases production and saves energy.

In order to achieve the above purpose, the utility model adopts the cantilever to support the inner rotor; the column supports the cantilever and the upper motor; the machine consists of a feed hopper (1), cantilever support (2), upper vertical shaft (3), inner rotor (4), Top motor (5), column (6), external rotor (7), bearing seat (8), bottom motor (9), bottom transmission (10), base (11) etc. constitute. Weld column (6) on base (11), column (6) top installs cantilever support (2), column (6) one side installs upper motor (5), cantilever support (2) and column (6) are connected with bolts, The upper vertical shaft (3) is installed on one end of the cantilever support (2), and the inner rotor (4) is fixed on the upper vertical shaft (3), and its top end is connected with the upper motor (5) through a V-belt pulley; the outer rotor is installed on the upper end of the bearing seat (8) (7), the lower motor (9) is installed at one end of the base (11), and is connected with the outer rotor (7) through the lower transmission (10). When working, the upper motor (5) drives the inner rotor (4) to rotate at high speed through the V-belt on the cantilever support (2); the lower motor (9) drives the outer rotor (7) to the inner rotor through the bearing seat (8) and the V-belt (4) Rotate at high speed in the opposite direction. After the material enters the crushing chamber from the upper feeding port (1), it is thrown by the inner rotor (4) at high speed, and the outer rotor (7) hits the material at a high speed in reverse. Next, the material is broken into powder; the qualified fine material can be screened and discharged by the built-in sieve, and the coarse material will continue to be crushed by impact.

Compared with a roller press plus a disperser or a column mill, the cantilever ultrafine pulverizer is small in size, simple in structure, and easy to maintain.

Compared with the patent No. ZL200420017744.6 internal screening double-rotor crusher, the cantilever-type ultra-fine pulverizer has a more compact structure and a smaller footprint, which is conducive to the transformation in the old factory building; it is more stable and reliable, and has fewer wearing parts;

Compared with the patent No. 200620097633.X frame-type pre-grinder, the cantilever ultra-fine pulverizer is easier to assemble, install and maintain.

Detailed ways

As shown in Figure 1, Figure 2, Figure 3, and Figure 4, the cantilever type ultrafine pulverizer consists of a feed hopper (1), a cantilever support (2), an upper vertical shaft (3), an inner rotor (4), and an upper motor (5), column (6), outer rotor (7), bearing housing (8), bottom motor (9), bottom transmission (10), base (11) etc. constitute. Weld column (6) on base (11), column (6) top installs cantilever support (2), column (6) one side installs upper motor (5), cantilever support (2) and column (6) are connected with bolts, An upper vertical shaft (3) is installed at one end of the cantilever support (2), and the inner rotor (4) is fixed on the upper vertical shaft (3). The outer rotor (7) is installed on the upper end of the bearing seat (8), and the lower motor (9) is installed on one end of the base (11).

When working, the brittle blocky material enters the crushing cavity from the upper feeding hopper (1), and the inner rotor (4) gets the power from the upper motor (5) at the other end of the cantilever support (2) through the triangle belt on the top of the upper vertical shaft (3) And high-speed rotation; the lower motor (9) drives the outer rotor (7) to rotate at a high speed in the opposite direction to the inner rotor through the lower bearing seat (8) through the lower transmission (10), and the material is thrown by the inner rotor (4) at high speed. The material is crushed into powder by the high-speed reverse impact of the outer rotor (7) under the action of strong impact and shearing; most of the fine powder is extracted by the fine powder extraction powder tube arranged on the top, and the remaining qualified fine material It can be screened and discharged by the built-in sieve, and the coarse material will continue to be crushed by impact.
