Abstract

A serial vibratom whose grinding shell is a regular polygon, the utility model relates to the serial vibratom, which is the vibratom integrating the techniques of a common round non-vibrating globe grinder and the vibratom and is used for manufacturing metallic allay powder materials and nonmetallic powder materials. The vibratom is two vibrating globe grinders of two inner polygonal grinding shells, which are in the same specification and model, are parallel in the axial direction and are installed on a horizontal base seat in interval, and vibrating isolating springs are arranged between bearing seats and bearing seat supports of the shell bodies of the vibratom. When in work, the rotating directions of the two grinders are opposite, which enables an exciting system to be vibrated only along the vertical direction and the vibration in the horizontal direction to be counteracted, rotation and vibration exist during the grinding process, which improves the functions of impacting, rubbing and cutting materials, reduces the time of abrasive materials and improves the grinding efficiency.

Description

The mill shell is the serial vibrating mill of regular polygon

Technical field

The utility model relates to a kind of serial vibrating mill, is to combine common round not vibrator and the processing metal alloy of vibrating mill technology and the vibrating mill of nonmetal powder.

Technical background

It is round not vibrator and vibrating mill two classes that the present most widely used equipment of grinding material mainly contains housing.

Housing rotates but non-vibrating grinding machine: can be divided into ball mill, rod mill, tumbling mill and autogenous tumbling mill according to the milling medium difference; According to ore discharge mode difference be divided into overflow mill, grid mill, peripheral discharge mill again, air swept mill; Can be divided into cylinder mill and conical disc mill again according to the cylindrical shell shape; Supporting way difference according to cylindrical shell can be divided into rolling bearing, sliding bearing, crawler shoe and holder rod again; Can be divided into edge transmission, center transmission, frictional drive, annular generator transmission again according to kind of drive difference.The principle of its ore grinding is: when in accordance with regulations rotation speed operation of ball mill, abrasive media, falls along parabolic path owing to the gravity effect breaks away from barrel after being thus lifted to certain altitude under the effect of centrifugal force and frictional force with ore.Then, they are thus lifted to certain altitude again, fall along parabolic path again again, so go round and begin again, and make the ore that is between the abrasive media effect of being hit and are crashed to pieces.Simultaneously, because the rolling and the slip of abrasive media, make particle be subjected to effect such as grinding, friction, shearing and ground.

Vibrating mill: vibromill is to make the grinding cylindrical shell forced vibration that is bearing on the spring system by vibrator, and the cylindrical shell that is in the judder state makes in it milling medium produce to impact intensely and grinds, thereby material is levigate.Present domestic vibromill has 2XLM series vibrating mill and 2GDZM series vibrating mill, and when its common characteristics were the work of drive motors drive vibrator, grinding mill barrel was done dither but do not rotated on support spring.External vibromill is the most representative and with strongest influence power, the commentaries on classics cavate vibromill that surely belongs to people such as the Gock invention of CLAUSTAHL (Clausthal) polytechnical university, be characterized in grinding when drive motors rotates shell and do not rotate and do high-frequency continuous shaking, but its mill shell chamber type is round.

Therefore, generally believe that in the industry to round not vibrator mainly be towards the research of maximizing; Over nearly 20 years, the research of this area mainly concentrates on 2 points in the world to vibrating mill: the first, transform the mill chamber shape, and improve the energy transport; The second, improve the relative velocity between medium, strengthen tangential friction effect.Round not vibrator rotates and does not vibrate, and abrasive media efficient is not high, though existing vibrating mill also can levigate material, the mill chamber shape is round, and the relative velocity between medium is strengthened tangential friction effect and is weaker than special-shaped chamber type.Granular material is carried out rapid and economic production, in a lot of industrial circles, seeming particularly important, so fast and effectively that material is the levigate equipment of research has become the task of top priority.

Summary of the invention

It is polygonal serial vibrating mill that technical problem to be solved in the utility model provides a kind of shell that grinds, not only rotate but also vibrate when it can make the work of grinding machine mill shell, the impact of material, grinding, shear action are rapidly and efficiently pulverized material thereby strengthened abrasive media.

The technical scheme that the utility model adopted is: the inner polygon that two axially parallels of same specification model are installed on horizontal base at interval grinds the vibrator of shell; Between the bearing block of vibrating mill housing and bearing bracket, isolation spring is housed.The mill thimble body section of this vibration grinding machine can adopt regular polygon, and the limit number of regular polygon is 5～11 limits, on one side on certain surface of grinding shell balancing weight is housed, Yi Bian the charging and discharging mouth all is located at certain two ends that the mill shell increases balancing weight.The bearing bracket of the transmission device support of motor and cycloidal-pin wheel decelerator and regular polygon mill thimble body is an isolating construction; motor and cycloidal-pin wheel decelerator connect with elastic coupling; the cycloidal-pin wheel decelerator connects with flexible coupling with the polygon grinding machine shell, covers at the feed inlet end that grinds the thimble body and is provided with protective gas import short circuit.The automatically controlled end of motor is connected with frequency converter by interface circuit, makes motor produce different rotating speeds, finally reaches the purpose that changes the grinding machine amplitude.

The beneficial effects of the utility model are:

1. employing such scheme, two same grinding machines are contained on the rigid body, and are symmetric arrangement.When the rotating speed unanimity of two grinding machines and rotation direction when opposite make only vertically vibration of excitation system, and the horizontal direction vibration is offset.

2. employing such scheme makes the abrasive media in the mill tube obtain three kinds of motions: 1. strong impelling, play the impact comminution effect to coarse-grained material; 2. rotation in the same way at a high speed plays abrasive action to material; 3. revolution at a slow speed plays the effect of homogenize material.

3. mill shell mill chamber has just polygonally been improved the sliding speed of medium and has produced centripetal acceleration by round changing into, and has strengthened the friction effect between medium, thereby fast and effectively that material is levigate; The introducing of balancing weight can further make the centre-of gravity shift of grinding machine, helps producing vibration.

4. by interface circuit, regulate the supply frequency of frequency converter input motor, make the rotating speed under the motor acquisition different frequency, thereby change the vibration amplitude of just polygonal mill shell.
