Description

Technical Field

[0001] The invention relates to the technical field of vibration mills, and in particular to a side-mounted double-mass vibration mill and a use method thereof. Background Art

[0002] Vibration mill is a kind of vibration mechanical equipment for superfine grinding of materials. It uses the exciting force generated by vibration to drive the grinding medium to vibrate at a certain frequency in the cylinder. The moving grinding medium impacts, crushes, shears and other effects on the material, so that the material is crushed. Traditional single-mass vibration mills have low efficiency, high noise, high energy consumption and short equipment life.

[0003] Most of the vibration mills currently in use adopt a single-mass structure design. The vibration mass composed of the exciter and the cylinder is installed on the foundation through a spring. The vibration is directly transmitted to the foundation, generating a large noise, and the environmental protection design of the vibration mill cannot be achieved. Secondly, the vibration frequency of the existing single-mass vibration mill design is far higher than the resonance frequency. The vibration frequency will inevitably coincide with the natural frequency when starting and stopping, and the equipment will resonate. At this time, the amplitude generated by the equipment is 4 to 7 times the working amplitude. The operation of the equipment becomes unstable and violent vibrations are generated, which is easy to cause fatigue damage to the body, prone to failure, and high maintenance costs. It is not conducive to the continuous production and will shorten the service life of the equipment. Third, the vibration frequency of the single-mass vibration mill is very high. The frequency of the equipment can reach 1000 to 1500 r / min when it is working. At this time, the equipment will generate a noise of ≥80dB, and even reach 180 to 200dB when it is turned on, which is bound to cause great noise pollution. Fourth, when the existing vibration mill is grinding, as the material in the cylinder increases, the mass of the vibrating mass increases, and the amplitude will gradually decrease, resulting in the grinding medium not being able to fully contact the material, the grinding effect becoming worse, the processing capacity being reduced, and the requirements of efficient processing cannot be met. Summary of the invention

[0004] In view of the above problems, an object of the present invention is to provide a side-mounted dual-mass vibration mill and a method for using the same.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

It is used for grinding aluminum ore materials. The particle size of the material after grinding is ≤200 mesh;

[0010] A vibrator is arranged in the middle of the open slot;

[0011] Vibration isolation springs are arranged at the bottom of the exciting body and the other side of the cylinder.

[0014] Further: the reinforcing rib segment comprises a plurality of reinforcing ribs, and the reinforcing ribs are arranged on the upper wall of the cylinder at intervals;

[0017] An eccentric block and a variable force wheel adjusting device are respectively arranged at both ends of the output shaft of the vibration motor; the eccentric block is connected with a counterweight block; and a protective cover is arranged outside the variable force wheel adjusting device.

[0018] Further: the top wall of the cylinder is provided with a feed pipe, a grinding feed pipe, and a dust removal pipe at intervals, and the feed pipe and the dust removal pipe are located on the cylinder outside the reinforcing rib group segment;

[0019] The upper parts of the feed pipe and the grinding feed pipe are both connected with a hopper;

[0020] The outside of the dust removal pipe is connected to an exhaust fan, which removes dust by negative pressure exhaust;

[0021] A discharge pipe is arranged on one side of the lower wall of the cylinder.

[0022] Further: a filter screen plate is provided in the cylinder at the end of the dust removal pipe to filter the ground material;

[0023] Both ends of the cylinder are provided with detachable end covers.

[0024] Furthermore: Amplitude sensors are arranged on the partition plates in the middle of the spring eccentric frame and the middle of the excitation body, and the amplitude sensors are connected to an external amplitude measuring instrument.

[0025] Furthermore: the connecting rods symmetrically arranged at both ends of the exciting body are connected to the outer wall of the cylinder, and the symmetrically arranged connecting rods are located on the side wall of the cylinder outside the reinforcing rib group segment.

[0026] Further: the lower part of the vibration isolation spring is arranged on the base, so as to isolate the spring horizontally.

[0027] A method for using a side-mounted dual-mass vibration mill, characterized in that the method comprises the following steps:

[0028] Step 1) The eccentric block of the vibration exciter rotates around the output shaft of the vibration motor to generate an eccentric exciting force, and the exciting body starts to vibrate. The exciting body is eccentrically arranged on the side of the cylinder, and drives the cylinder to vibrate through the main vibration spring; the amplitude measuring instrument monitors the amplitude of the cylinder, and feeds back the signal to the PLC control system through the amplitude sensor. When the amplitude exceeds the set safety threshold, the PLC control system will issue an alarm and execute a shutdown command; when the material increases or decreases, the amplitude changes, and the PLC control system drives the pneumatic control cabinet to control the variable force wheel adjustment device to inflate and deflate, adjust the relative distance between the center of gravity of the eccentric block and the rotation axis of the output shaft of the vibration motor, and control the amplitude of the vibration mill;

[0029] Step 2) the material enters the cylinder through the feed pipe, and the cylinder is filled with grinding media of different diameters. The grinding media in the cylinder performs a composite motion of circular, elliptical and linear vibrations; the exciting body is eccentrically arranged, the cylinder vibrates, and performs a reciprocating small-angle swing along the circumferential direction of the cylinder, and the grinding media and material mixture in the cylinder performs a cyclic rolling along the circumferential direction of the cylinder, and the material is ground;

[0030] Step 3) After being crushed by the grinding medium, the material passes through the filter screen and is discharged from the discharge pipe; the material that does not meet the particle size requirements will be returned to the vibration mill cylinder through the grinding feed pipe for re-grinding.

[0031] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0032] (1) The vibrating body and the vibrator form the lower mass body; the main vibration spring, spring eccentric frame, reinforcing ribs, and cylinder form the upper mass body; both ends of the vibrating body are connected to the outer wall of the cylinder through connecting rods. The structural setting of the upper mass body, the lower mass body, and the vibration isolation spring constitutes a side-mounted double-mass vibration mill that is efficient, energy-saving, environmentally friendly, and has a long service life. The vibration isolation spring adopts a rubber and metal composite spring. The rubber and metal composite spring has good nonlinear characteristics and can adapt to the uneven load changes of the vibration system. The vibration isolation effect is obvious and can effectively reduce vibration and noise. The cylinder is equipped with a polyurethane wear-resistant lining, which can reduce noise and impact and is easy to replace. The double-mass vibration mill reduces the vibration directly transmitted to the foundation and reduces noise.

[0033] (2) The variable force wheel adjustment device adjusts the relative distance between the center of gravity of the eccentric block and the rotation axis of the output shaft of the vibration motor by inflating and deflating, thereby controlling the amplitude and vibration intensity of the vibration mill.

[0034] (3) The exciting body and the cylinder form a specific mass ratio, and the vibration frequency is controlled so that it is always lower than the natural frequency, thus forming a sensitive sub-resonance system. At this time, a low-power vibration motor is used to drive the exciting body to vibrate. At the same time, the exciting body itself has a certain mass. Driven by the vibrator, it will generate a large centrifugal force and inertial force. The main vibration spring stores energy. Under the action of the centrifugal force and inertial force generated by the exciting body, the main vibration spring is compressed. When compressed to the limit, the energy stored in the main vibration spring will be released and transferred to the cylinder in the form of working amplitude, thereby driving the cylinder to vibrate. The amplitude is multiplied by the main vibration spring group. Using a smaller exciting force to obtain a larger amplitude can minimize the power of the equipment motor and achieve energy-saving effects.

[0035] (4) The inside of the cylinder is filled with grinding media of different diameters. Under the action of the circumferential excitation force, the grinding media in the cylinder performs a compound motion of circular, elliptical and linear vibrations. Due to the eccentric arrangement of the excitation body, the cylinder vibrates and makes a small reciprocating swing along the circumferential direction of the cylinder, so that the grinding media and material mixture in the cylinder roll in a circular manner along the circumferential direction of the cylinder. This can promote the flow of materials, make the materials more fully ground, and greatly improve the grinding efficiency of the vibration mill. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Embodiment 1:

[0043] A side-mounted dual-mass vibration mill, comprising: a cylinder 1, a main vibration spring 2, an exciter 3, a vibration isolation spring 4, an exciter 5, a connecting rod 8, a filter screen plate 9, a feed pipe 10, a grinding feed pipe 11, a counterweight 12, an eccentric block 13, a vibration motor 14, a protective cover 15, a variable force wheel adjustment device 16, a base 17, a partition plate 18, a spring eccentric frame 19, a reinforcing rib 20, a dust removal pipe 21, a hopper 22, and a discharge pipe 23;

[0044] The heights of the two ends of the base 17 are inconsistent. Vibration isolation springs 4 are arranged on both sides of the base 17. An exciter 3 is arranged on the vibration isolation spring 4 on the lower end of the base 17. The exciter 3 is arranged as an open slot with one side open. The exciter 5 is installed in the middle of the open slot of the exciter 3 by bolts. The exciter 3 and the exciter 5 form a lower mass. Partition plates 18 are arranged at intervals in the shell of the exciter 3. The arrangement of the partition plates 18 serves to increase the excitation intensity of the exciter 3. A row of main vibration springs 2 are arranged on the upper part of the exciter 3. The upper end of the main vibration spring 2 and the top of the vibration isolation spring 4 on the lower and higher ends of the base 17 are connected with a spring eccentric frame 19, and are located on both sides of the cylinder 1. The spring eccentric frames 19 on both sides are connected to the reinforcing rib group segment, and the reinforcing rib group segment is composed of a plurality of reinforcing ribs 20. The two ends of the reinforcing ribs 20 are connected to the spring eccentric frame 19, and the reinforcing ribs 20 are covered on the outer wall of the cylinder 1. The main vibration spring 2, the spring eccentric frame 19, the reinforcing ribs 20, and the cylinder 1 constitute the upper mass body; both ends of the exciting body 3 are connected to the outer wall of the cylinder 1 through the connecting rod 8. The structural setting of the upper mass body, the lower mass body, and the vibration isolation spring 4 constitutes a side-mounted double-mass vibration mill with high efficiency, energy saving, environmental protection, and long service life. The position of the partition plate 18 is located on both sides of the exciting body 3 with the main vibration spring 2 and the mounting hole of the main vibration spring 2 to increase the strength of the structure.

[0045] Removable end caps are installed at both ends of the cylinder 1. The top of the cylinder 1 is connected with a feed pipe 10, a grinding feed pipe 11, and a dust removal pipe 21 in sequence. The feed pipe 10 and the grinding feed pipe 11 are connected with a hopper 22 on their upper parts to facilitate the entry of materials; the dust removal pipe 21 is connected to an exhaust fan on the outside to form a negative pressure for dust removal; a filter screen plate 9 is arranged in the cylinder 1 on one side of the dust removal pipe 21, and a discharge pipe 23 is connected to the lower wall of the cylinder 1 on the side of the filter screen plate.

[0046] Amplitude sensors are provided in the middle of the spring eccentric frame 19 and on the partition plate 18 in the middle of the excitation body 3, and the amplitude sensors are connected to an external amplitude measuring instrument.

[0047] Vibrator 5: includes: counterweight 12, eccentric block 13, vibration motor 14, protective cover 15, variable force wheel adjustment device 16; counterweight 12 is connected to eccentric block 13 by bolts, eccentric block 13 and variable force wheel adjustment device 16 are respectively installed at both ends of the output shaft of vibration motor 14, and a protective cover 15 is arranged outside variable force wheel adjustment device 16 to play a protective role. Variable force wheel adjustment device 16 adjusts the relative distance between the center of gravity of eccentric block 13 and the rotation axis of the output shaft of vibration motor 14 by inflating and deflating, thereby controlling the amplitude and vibration strength of vibration grinding.

[0048] The main vibration spring 2 adopts a metal spiral variable pitch spring, and the main vibration spring 2 is connected to the excitation body 3 and the cylinder 1 through bolts respectively.

[0049] The vibration isolation spring 4 is a rubber and metal composite spring, and the vibration isolation spring 4 is connected to the excitation body 3 and the cylinder 1 respectively by bolts; the rubber and metal composite spring has good nonlinear characteristics, can adapt to the uneven load changes of the vibration system, has obvious vibration isolation effect, and can effectively reduce vibration and noise.

[0050] A polyurethane wear-resistant lining is installed inside the cylinder 1, and the polyurethane wear-resistant lining is connected to the cylinder 1 by bolts; the polyurethane wear-resistant lining can reduce noise and impact, has the characteristics of impact resistance, corrosion resistance, long service life, and is easy to replace.

[0051] Working process: The exciter 5 is installed on the excitation body 3 by bolts, the upper part of the excitation body 3 is connected to the spring eccentric frame 19 through the main vibration spring 2, and the two sides of the upper part of the excitation body 3 are connected to the outer wall of the cylinder 1 through the connecting rod 8; the lower part of the excitation body 3 is connected to the base 17 through the vibration isolation spring 4, and the excitation body 3 is eccentrically arranged on the side of the cylinder 1.

[0052] During operation, the eccentric block 13 of the vibrator 5 rotates around the output shaft of the vibration motor 14 to generate an eccentric exciting force. Under the action of the eccentric exciting force, the vibrator 3 starts to vibrate and drives the cylinder 1 to vibrate through the main vibration spring 2; the material enters the cylinder 1 through the feed pipe 10, and the material is mainly aluminum ore, which enters the cylinder 1 through the feed pipe 10.

[0053] The cylinder 1 is filled with grinding media of different diameters. Under the action of the circumferential excitation force, the grinding media in the cylinder 1 performs a composite motion of circular, elliptical and linear vibrations. Due to the eccentric arrangement of the excitation body 3, the cylinder 1 vibrates and performs a small reciprocating swing along the circumferential direction of the cylinder, so that the grinding media and the aluminum mineral material mixture in the cylinder roll in a circular manner along the circumferential direction of the cylinder, which can promote the flow of the aluminum mineral material, make the material grinding more fully, and greatly improve the grinding efficiency of the vibration mill. After repeated beating and rolling by the grinding media, cracks are generated and gradually crushed. The fine aluminum mineral material passes through the filter screen plate 9 and is discharged from the discharge pipe 23 and enters the next process. After screening in the next process, the material that does not meet the particle size requirements will be returned to the vibration mill cylinder 1 from the grinding feed pipe 11 for re-grinding. The dust in the cylinder 1 is discharged through the discharge pipe 23 under the action of the exhaust fan.

[0054] The magnitude of the vibration frequency depends on the mass ratio of the excitation body 3 to the cylinder 1. By controlling the mass ratio of the excitation body 3 to the cylinder 1, the vibration frequency is controlled so that the vibration frequency is always lower than the natural frequency, thus forming a sensitive sub-resonance system. At this time, a low-power vibration motor is used to drive the excitation body 3 to vibrate. At the same time, the excitation body 3 itself has a certain mass. Driven by the exciter 5, it will generate a large centrifugal force and inertial force. The main vibration spring 2 has the function of storing energy. Under the centrifugal force and inertial force generated by the excitation body 3, the main vibration spring 2 is compressed. When compressed to the limit, the energy stored in the main vibration spring 2 will be released and transferred to the cylinder 1 in the form of working amplitude, thereby driving the cylinder to vibrate. The amplitude is multiplied by the main vibration spring 2 group. By using a smaller exciting force to obtain a larger amplitude, the motor power of the equipment can be reduced to the maximum extent, achieving an energy-saving effect.

[0055] The exciter 5 is composed of a vibration motor 14, an eccentric block 13, a variable force wheel adjustment device 16, a counterweight block 14, and is equipped with an amplitude measuring instrument and an amplitude sensor. When the equipment is running, the equipment amplitude is monitored by the amplitude measuring instrument, and the signal is fed back to the PLC control system through the amplitude sensor. When the amplitude exceeds the set safety threshold, the PLC control system will issue an alarm and execute a shutdown command to prevent the equipment from being damaged by crossing the resonance zone for a long time. In addition, the PLC control system can monitor the operation of the equipment according to the feedback signal. When the material increases or decreases, the equipment amplitude will change. The PLC control system drives the pneumatic control cabinet to control the variable force wheel adjustment device 16 to inflate and deflate, adjust the relative distance between the center of gravity of the eccentric block 13 and the axis of rotation of the output shaft of the vibration motor 14, and then control the amplitude and vibration strength of the vibration mill to achieve efficient processing of the vibration mill. The PLC control system and the pneumatic control cabinet are both common equipment and have not been improved, and common equipment can all achieve this operation.

[0056] When the vibration mill starts and stops, the start-stop program set by the PLC system drives the pneumatic control cabinet to control the variable force wheel adjustment device 16 to inflate and deflate, adjust the relative distance between the center of gravity of the eccentric block 16 and the rotation axis of the output shaft of the vibration motor 14, and then control the amplitude and vibration intensity when the vibration mill starts and stops, so as to realize the vibration-free start and stop of the vibration mill, avoid crossing the resonance zone due to severe vibration when the vibration mill starts and stops, and cause damage to the equipment, which can effectively reduce the failure rate of the vibration mill.

[0057] The aluminum ore is ground in the cylinder 1, and the mesh number of the filter screen plate 9 is 200 meshes. The particle size of the material after grinding is ≤200 meshes. The energy-saving effect is calculated based on the kilowatt-hours used for processing each ton of material, and the energy-saving effect can reach 35%-50%. It saves energy and improves the grinding efficiency. The particle size after grinding is convenient for ore dressing operation.

[0058] Although the present invention is described herein with reference to a number of illustrative embodiments of the present invention, it will be appreciated that those skilled in the art may devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, within the scope of the present disclosure, drawings, and claims, a variety of variations and modifications may be made to the components and / or layout of the subject combination layout. In addition to the variations and modifications made to the components and / or layout, other uses will also be apparent to those skilled in the art.
