Abstract

The utility model relates to a self-grinding separator which is mainly provided with a cylindrical-shaped rotating screen and a cone-shaped rotating screen. An inner chamber is provided with a self-grinding separation chamber and a separation chamber, while the wall of the self-grinding separator is provided with a plurality of screen bores with the same bore diameter; both sides of the self-grinding separator are respectively provided with a big toothed ring and a pinion gear which is arranged on a motor shaft, and the big toothed ring and the pinion gear are in mesh; a new entering hollow shaft and a hollow separation shaft are arranged in respective bearing seats. The appearance of the utility model can automatically separate and remove various impurities which are mixed in a coal handling system such as iron blocks, gangues, gun lines, etc. Therefore, the utility model solves the key point which can not be solved in the thermal power generation for years, and the process moving is simplified, while an electric magnetic iron removing crusher is saved to reduce the workload of the coal grinding mill, and thus, the self-grinding separator is particularly suitable for using in the thermal power plants to remove the impurities mixed in the coal handling system.

Description

Self-grinding separator
The utility model relates to a kind of autogenous grinding seperator, be particularly suitable for the thermal power plant and automatically separate the machinery equipment of multiple foreign material such as removing the wooden unit of sneaking in the coal handling system, iron block, spoil, big gun line, also can be used in other technological processes that need remove these foreign material.
The Wood-removing device that the roller picker principle of Power Plant in China coal handling system employing is at present made is owing to can not remove above-mentioned foreign material effectively; cause serious prestige to assist for the normal operation of pulverized coal preparation system machinery equipment; often because of foreign material such as wooden unit not Ex-all pulverized coal preparation system is stopped up shut down, this problem is a thermal power plant coal handling system key issue anxious to be solved always.Yet external thermal power plant, use be the high-quality marketable coal, do not have above-mentioned foreign material, just do not remove naturally yet coal flow in the machinery equipment of foreign material such as wooden unit.
The purpose of this utility model be to provide a kind of with coal cinder after autogenous grinding, separate and remove the machinery equipment of multiple foreign material such as the wooden unit of sneaking in the coal handling system of thermal power plant, iron block, spoil, big gun line automatically.
The purpose of this utility model realizes by the following technical solutions, its design philosophy is with autogenous tumbling mill, the autogenous grinding seperator that tubular and taper trundle screen three's principle organic assembling forms, mainly be by tubular and taper trundle screen 7,9, its inner chamber is provided with autogenous grinding separation chamber 6 and separation chamber 11, barrel has the sieve aperture of plurality of rows with the aperture, there is protective cover 8 outside, the pinion that its bilateral symmetry is equipped with on 14 in big gear ring 4 and the motor is meshed, charging quill shaft 3 and hollow declutch shaft 13 are loaded on respectively in the bearing block 12 at two ends, the left and right sides, and an end of charging slide carriage 2 tiltedly stretches in 3 mouthfuls of the charging quill shafts.
The inboard, edge of described tubular and taper trundle screen 7,9 is distributed on the autogenous grinding riser 5 that is equipped with respectively on the circumference more than 4 vertically and separates riser 10.
The assembling axis of described autogenous grinding seperator is with the downward-sloping 1.5-4 of horizontal axis °.
The utility model has the separative efficiency high noisy little, how function has replaced not only that Wood-removing device need not electric magnetic iron remover, disintegrating machine can also reduce the workload that opens the coal machine, simplified advantages such as thermal power plant coal handling system technological process and economic results in society are remarkable, implemented to be beneficial to easily simultaneously to apply.
Fig. 1 is a vertical structure schematic diagram of the present utility model.
Accompanying drawing is an embodiment of the present utility model.
When the utility model uses, be to be undertaken by following mode, the raw coal of shipping for last power supply by belt conveyer 1, handle through probability screen, under wherein most of discharge sieve less than screen size, the oversize of remainder enters into autogenous grinding separation chamber 6 by charging quill shaft 3, because tubular and taper trundle screen 7,9 rotate with certain speed, material wherein is by self-grinding action, coal cinder is pulverized until less than screen size, and these uts and coal dust are outside the eliminating machine, be mixed in wooden unit wherein, foreign material such as iron block and spoil, because its mechanical-physical character is different with coal, therefore, can not pulverized because of autogenous grinding, at last outside the port eliminating machine that separates quill shaft 13, thereby realize the purpose that autogenous grinding separates.
