Laminated planet ring grinding mill

The technical field is as follows:

the invention relates to a machine for grinding by using a grinding element with combined action of a roller and a ring, in particular to a laminated planet ring grinding machine.

Background art:

the grinding machinery used in modern powder industry mainly comprises: ball mills, vertical mills, double-roll mills, hammer mills, Raymond mills, wheel mills, vibratory mills, sand mills, bowl mills, swept mills, cage mills, steel claw mills, turbine mills, steam mills, flour mills, and the like. Although the devices have different structures, the working principle is to crush the particles by using pressure, gravity, inertia force and friction force. The fine powder or the ultra-fine powder needs to be processed by powder grading equipment and dust collecting equipment. The equipment has the advantages of complex grinding process, great environmental pollution, high loss of grinding materials, large equipment volume, light weight, large land occupation area and high capital construction and installation investment cost. The energy consumption is high, and the power consumption of the powder industry accounts for 1/3 of industrial power consumption.

The theory of crushing and grinding particles by utilizing normal force is already researched and summarized by Chinese science and technology workers in the twentieth century, and the technology is confirmed to be internationally leading and internationally pioneering. Lays a theoretical foundation for the advanced technology. The engineering technicians in China continuously design and develop novel grinding equipment by applying the technology. Column mills, ring mills, throw-away ring mills, moving-axis ring mills, floating-mill ring mills, stacked planetary vertical mills, etc. have appeared in succession, and a number of related patents have been published domestically. The development of these devices has been combined theoretically and practically with the characteristics of high efficiency, energy saving, environmental protection and material saving. However, the grinding structure of these devices is not reasonable, and the ground powder can not directly meet the powder requirement of the product. The mechanical transmission is not ideal, and the grinding wheel and the grinding ring (lining plate) are seriously abraded due to the high-speed strong friction between metals. The driving part of the grinding wheel has unreasonable structure and short service life. The unreasonable grinding structure causes the mixed material of thickness, leaks the material and runs the material, makes the powder thickness of grinding uneven, needs to pass through powder classification, needs further coarse fodder feedback regrinding. The unreasonable structure of the equipment causes the ash entering and blocking of the device, so that the equipment cannot work continuously. Because the series of technical problems are not solved, the ring milling powder processing technology is not well popularized and applied.

The invention aims to provide a novel mechanical structure based on further research, design, experiment and development of a laminated planet ring mill and a laminated planet vertical mill, wherein the grinding process and the structure are more reasonable, the ground powder can be randomly regulated and controlled according to the product requirements, and the high-speed strong friction phenomenon between metal cannot occur in the normal grinding process of a grinding wheel and a grinding ring. The grinding wheel driving structure has long service life and can automatically adjust the matching surface of the grinding wheel and the grinding ring. And has the characteristics of convenient maintenance and simple operation. Can achieve the purposes of safety, environmental protection, reduction of grinding material loss, small volume and light weight. Can greatly reduce the power consumption of powder processing.

In order to achieve the aim, the laminated planet ring grinding machine comprises a transmission device, a grinding body, a base, a grinding cylinder hooping hydraulic lifting mechanism, a grinding cylinder hydraulic unfolding and closing mechanism, a feeding hopper, a discharging hopper and a vent pipe, wherein the transmission device comprises a motor, a one-way coupling, a universal transmission joint shaft and a speed changer. The feed hopper and the vent pipe are positioned above the upper cover of the grinding body, and the discharge hopper is positioned below the base of the grinding body.

The grinding body part of the invention mainly comprises a grinding cylinder body A and a grinding cylinder body B which are oppositely arranged on the left and right, a main shaft, a grinding ring, a material equalizing disc, a turntable, a bottom turntable, a grinding wheel cantilever lifting and swinging mechanism assembly, an upper cover, a base and a frame.

The upper cover is provided with a feed hopper, a main bearing seat and a vent pipe installation position.

The material equalizing disc is disc-shaped, the periphery is provided with a convex material sweeping head, and the bottom of the disc is provided with a material blocking arc skirt board.

The turntable is in a star-shaped disc shape, the center of the disc is provided with a shaft sleeve, and the disc surface is provided with a plurality of round holes.

The base is provided with a petal-shaped hollow window and a bottom bearing seat, and the outer ring is provided with a circular flange, a square concave retainer ring and an inclined plane step ring.

The main shaft is a long cylindrical shaft, is provided with a central cylindrical long blind hole and is arranged in the center of the grinding body.

The grinding wheel cantilever lifting and swinging mechanism assembly consists of a cantilever, a grinding wheel bearing seat, a cantilever swinging shaft pin, a grinding wheel shaft, a round nut, a grinding wheel bearing, a swinging shaft pin bearing and a sealing ring. The grinding wheel is divided into a plurality of crushing wheels, coarse grinding wheels and fine grinding wheels. The inverted structure of the bearing seat of the grinding wheel cantilever lifting and swinging mechanism assembly can prevent dust from invading into the grinding wheel bearing mechanism.

The hydraulic lifting mechanism for the hooping ring of the grinding cylinder body is characterized in that an upper hooping ring and a lower hooping ring are arranged at two ends of the grinding cylinder body, and the inner ring of the hooping ring is a conical ring and is matched with conical ring mortises and tenons at two ends of the grinding cylinder body. The grinding cylinder body can be hooped or loosened through the movement of the hydraulic oil cylinder. The tightening ring is provided with a lifting guide shaft.

The milling barrel hydraulic rotary unfolding and closing mechanism is formed by assembling an upper rotary shaft, a lower rotary shaft, a shaft seat, a plane thrust bearing, a bearing backing ring, a round nut, a milling barrel A, B shaft lug, a hydraulic oil cylinder and a hydraulic oil cylinder rear seat beam. The grinding cylinder A, B components can be rotated and unfolded by about 90 degrees or closed by the driving of the hydraulic oil cylinder.

The working process of the invention is as follows: the motor is started, power is transmitted to the speed reducer through the one-way coupling and the universal transmission shaft to drive the main shaft, the main shaft drives the material equalizing disc, the rotary disc and each layer of grinding wheel cantilever swinging type rotating mechanism assembly on the bottom rotary disc to enable the grinding wheels to roll along the grinding rings, each layer of grinding wheel cantilever swinging type rotating mechanism assembly revolves around the main shaft, and the grinding wheels roll along the grinding rings to rotate around the grinding wheel shafts in a planetary reverse direction. The material particles are added by a feed hopper, enter the mill body through a feed inlet of an upper cover of the mill body, are uniformly broadcast through rotation of a material homogenizing disc, fall into a concave-convex inclined crushing groove of a first layer of crushing ring, and are subjected to circular motion to generate huge normal and tangential rolling forces to act on the grinding ring, so that the material particles are rolled and crushed by the grinding wheel, fall onto a turntable, and are broadcast through rotation of the turntable, fall onto an upper table top of a second layer of grinding ring, form a stacking slope ring, naturally slide and cut between the coarse and fine grinding ring and the grinding wheel, and roll and crush the material particles through the coarse grinding wheel with the normal and tangential rolling forces, and fall onto the turntable. The particles are ground into fine powder or ultrafine powder from coarse to fine, and the fine powder or ultrafine powder falls to a base, falls to a conical hopper through a petal-shaped hollow window of the base and is milled out of the conical hopper.

The grinding ring is a fixed circular rail ring, and the main shaft drives the material homogenizing plate, the turntable and the bottom turntable which are provided with a plurality of groups of grinding wheel cantilever lifting and pushing type transmission mechanism assemblies to revolve around the main shaft along the grinding ring. The roller performs circular planetary motion to generate a normal force Fn and a tangential force F and drives the roller to perform planetary motion along the roller ring. The normal force Fn acts on the grinding ring through the grinding wheel, and the grinding ring generates a reaction force N, so that a strong rolling force is formed between the grinding ring and the grinding wheel. The formula for the normal force is as follows:

Fn＝M V²(1)

fn is a normal force

Angular velocity of V ═

Moment of the grinding wheel

The operation according to the formula (1) concludes that the grinding wheel can generate normal force which is tens or hundreds times larger than the dead weight during the running process of the planet. This force is sufficient to break down any breakable particles.

The planetary motion of the grinding wheel along the grinding ring is equal to that of the wheel rolling on the steel rail, and the friction force arm coefficient of the cylindrical wheel rolling on the steel rail is 0.05-0.07. The roller can be driven with only small kinetic energy. The object particles are broken by the rolling force of the rolling wheel along the concave-convex inclined grooves and the inclined ring surface on the periphery of the rolling ring. If the resistance of the particles entering between the grinding ring and the grinding wheel is too large, the grinding wheel can swing and retreat along with the swinging shaft. The particles will cause a certain resistance to the rolling roller, which resistance coefficient is between 0.1 and 0.3. The grinding wheel performs planetary motion along the grinding ring, the kinetic energy of the driving required by the purpose of processing the powder by rolling and grinding the particles is very small, and the function consumption calculation formula is as follows:

N_wheel＝∑M Vk1…kn (2)

N_WheelThe kinetic energy required by the running of the grinding wheel.

M is the rotation moment of the grinding wheel

V-line speed.

k1 … kn is the resistance coefficient affecting the running of the roller.

And (3) operating the grinding wheel to perform rail surface rolling circumferential operation according to the formula (2), and rolling and grinding the particles by utilizing the generated normal force to process the powder. The kinetic energy consumed to drive the grinding wheel is small. The normal force generated by the rolling wheel in circular motion is tens or hundreds times larger than the dead weight, the rolling force is enough to crush the crushable particles, and the structure of the invention has the effect of energy saving completely.

The other big structure of the invention is characterized in that; a grinding body with multiple processes is vertically overlapped by multiple sets of grinding rings and a grinding wheel cantilever lifting swing type rotating mechanism, and is divided into multiple grinding processes such as coarse crushing, fine crushing, coarse grinding, fine grinding and the like from top to bottom. The grains become thinner gradually from coarse to fine, and the phenomenon of coarse and fine mixed grinding cannot be caused. The grinding wheel acts directly on the particles by means of normal forces. The particles flow through the mill body rapidly and are crushed by the strong rolling force, and the phenomena of material leakage and material mixing are avoided. The particles naturally slide and rapidly pass through each procedure, the particles are cut into the space between the grinding ring and the grinding wheel in a very uniform state, naturally slide from top to bottom and uniformly flow through each procedure, and the particles can be ground into fine powder or ultrafine powder in the grinding body only within a short time. Therefore, the invention can achieve the effect of high-efficiency grinding.

According to the structure of the invention, the grinding wheel utilizes the normal force to roll the particles to achieve the grinding principle. The larger the normal force, the finer the particles are crushed. The grinding fineness of the mill can be adjusted by only changing the angular speed of the grinding wheel. The invention adopts variable frequency variable speed control to carry out stepless speed regulation, and can lead the running angular speed of the grinding wheel of the grinding machine to carry out stepless speed change. The grinding machine can control the grinding fineness according to the requirements of hardness, granularity and product fineness of the ground particles, and the fineness of the ground powder is ensured to be uniform and qualified. Can be used for preparing fine powder or superfine powder without powder grading equipment. The product can directly meet the required fineness requirement. The grinding process can be simplified, and the dust pollution can be reduced.

The invention adopts a variable frequency variable speed control system, can start the equipment at low frequency and low speed, reduces the rotating torque during starting and stabilizes the starting current of the motor. The drive power system configuration can be mitigated. The control system can be networked with an electronic computer for remote control.

The invention has the characteristics of light weight and small volume. Compared with a ball mill with the same output and grinding fineness, the ball mill has the volume below 1/5 and the weight of 1/10-1/20. The invention can save a large amount of steel consumption in manufacturing. In the aspect of design and construction investment of a factory building, the occupied land can be reduced, the auxiliary equipment of the grinding process can be reduced, the structure and the building area of the factory building can be reduced, and a large amount of capital construction and installation cost can be saved.

The invention can not generate impact and vibration sound during operation, and the sound generated during operation is very low. The invention can improve the working environment of the powder processing industry. Reduce dust and noise pollution.

The invention uses the grinding wheel to roll and grind the particles to achieve the purpose of processing the powder, the grinding ring and the grinding wheel mainly work by rolling grinding force during operation, and the influence of the grinding force is very small, so the grinding ring and the grinding wheel are very little abraded.
