Detailed description of the invention
Below in conjunction with the progress being embodied as form and the accompanying drawing substantive distinguishing features and significance so that the present invention to be described.Ying Li
Solving, these embodiments are only used for being further described the present invention, it is impossible to be interpreted as limiting the scope of the invention.
Ball mill is after material is broken, then carries out the key equipment pulverized, and is widely used height in commercial production
Various Ores and other grindability material are carried out dry type by one of fine grinding machinery, it is adaptable to the various Ore of grinding and other material
Or wet type grinding, it is widely used in ore dressing, the industry such as building materials and chemical industry.
Ball mill is generally made up of major parts such as cylinder, feed portion, discharging portion, rotating part, driving sections.It is said that in general,
The liner plate made with high-abrasive material can be studded with in cylinder, there is carrying cylinder and maintain its bearing rotated, also there is drive division
Grade.The cylinder that the cylinder of ball mill is usually long, cylinder can be steel plate manufacture built with abrasive body, cylinder, have steel liner plate and
Cylinder is fixed, and abrasive body may generally be steel ball, and can load in cylinder by different-diameter and certain proportion, and abrasive body also can be used
Steel section.
Granularity according to grinding material is selected, and material is loaded in cylinder by ball mill feed portion, works as ball mill barrel
When rotation, abrasive body, due to inertia and centrifugal action, the effect of frictional force, makes it be attached on shell liner by cylinder band
Walking, in time being brought to certain height, left due to the action of gravity of itself, the abrasive body of whereabouts is as projectile one
Material in cylinder is smashed by sample.
Fig. 1 shows the ball mill of the embodiment according to the present invention；Fig. 2 shows the side of the ball mill shown in Fig. 1
View.As depicted in figs. 1 and 2, ball mill 1 possesses cylinder 2, and the two ends of this cylinder 2 are set up in frame 3, with this by frame 3
Tube-holding body 2.Additionally, be wound with V belt 4 on the outer wall of cylinder 2, rotated by transmission system drives V belt 4, and then
Cylinder 2 is driven to rotate, it is achieved ball milling.
Specifically, as it is shown in figure 1, the output shaft of reductor 7 is in transmission connection with V belt 4, such as, reductor 7 is defeated
Shaft can be connected with the power transmission shaft being supported on drive bearing block 20 via pin coupler 19, thus can be by reductor 7 through this
Power transmission shaft drives the operating of V belt 4 direction of arrow as shown in Figure 2.
Power shaft one end of reductor 7 is connected with the output shaft of active motor 5 by coupling device 6, the power shaft of reductor 7
The other end is connected with the output shaft of reductor 9 by clutch mechanism 10, and the power shaft of reductor 9 and stand-by motor 8 is defeated
Shaft connects.Additionally, also as it is shown in figure 1, be provided with brake 11 on the output shaft of stand-by motor 8.In this embodiment, on
Stating reductor 7 can be bull gear reducer, and reductor 9 can be primary reduction gear speed machine.
Ball mill 1 according to said structure, after filling it up with raw material, first stand-by motor 8 passes through primary reduction gear speed machine 9 with big
Through being driven cylinder 2 to rotate by V belt 4 after the deceleration of gear reduction unit 7.Stand-by motor 8 is by primary reduction gear speed machine 9 simultaneously
Also the rotor driving active motor 5 rotates.After the stand-by motor 8 operating provisions time, start active motor 5.When active motor 5
By speed change the spinning up cylinder 2 of coupling device 6 and bull gear reducer 7, cylinder 2 speed exceedes stand-by motor 8 and is carried
During the speed moved, clutch mechanism 10 generation effect, stand-by motor 8 is no longer to bull gear reducer 7 output, stand-by motor
8 there is idle running, at this moment will turn off the power supply of stand-by motor 1.Cylinder 2 is accelerated until doing after rated speed by active motor 5
Uniform rotation.Stand-by motor 8 and primary reduction gear speed machine 9 are auxiliary system, and active motor 5 and reductor 7 are host computer system.When entering
Then and main frame after complete material, successively auxiliary system (3-5 minute).Both are autonomous system (being operated respectively by clutch).This
Outward, the distance that screw mandrel 22 can be used for adjusting brake rubber block 12 with brake rim 13 is adjusted.
Additionally, when needs make ball mill 1 stop ball milling operation, make cylinder 2 underdrive by brake 11 until complete
Full cut-off is only.In the prior art, magnetic-type braking mechanism has been used to brake.Fig. 4 shows ball mill in prior art
The structural representation of magnetic-type braking mechanism；Fig. 5 shows the top view of the magnetic-type braking mechanism shown in Fig. 4.
As shown in Figure 4 and Figure 5, existing magnetic-type braking mechanism generally includes solenoid 17, with this solenoid 17
The spring 18 being connected, spring 18 and then be connected with brake rubber block 12 by bindiny mechanism.Use this magnetic-type braking mechanism, work as electromagnetism
Coil 17 brakes when being energized, and is exerted a force brake rubber block 12 by spring 18, makes brake rubber block 12 hold brake rim 13 tightly.And in power-off
Time, spring 18 resets, thus releasing of brake skin 12 and brake rim 13.But, as described above, the expense of magnetic-type braking mechanism
Higher and brake security is relatively low.
Therefore, in the present invention, in order to solve the magnetic-type braking mechanism of ball mill in prior art costly and
The defect that brake security is relatively low, it is provided that a kind of air-cylinder type braking mechanism.Fig. 3 shows the air-cylinder type braking mechanism of the present invention
The structural representation of an embodiment.
As it is shown on figure 3, air-cylinder type braking mechanism can include electromagnetic valve 14, this electromagnetic valve 14 can pass through trachea and cylinder 15 phase
Even, this cylinder 15 carries out stretching motion along screw rod 16, and is connected with brake rubber block 12 by bindiny mechanism.This air-cylinder type is used to stop
Mechanism of car, compressed air as shown by the arrows in Figure 3, enters cylinder 15 by trachea, controls stretching of cylinder 15 by electromagnetic valve 14
Contracting motion.Specifically, the control principle drawing of the cylinder during Fig. 6 shows the braking mechanism shown in Fig. 3.As shown in Figure 6, by right
The power on/off control of electromagnetic valve 14, it is achieved outlet I/ outlet II ventilation switching.During energising, outlet I ventilation, cylinder 15 moves to left, and receives
Tight brake gear；During power-off, outlet II ventilation, cylinder 15 moves to right, and loosens brake gear.Slow down when clutch mechanism 10 is ratcheting
With slave machine even, ball mill barrel 2 is driven slow rotation by slave to machine 7 high speed shaft, and now brake system can be entered when shutting down
Row operation, positions cylinder 2.When clutch mechanism 10 separates, can start main frame, brake system is inoperative.
According to the present invention, the object of control becomes cylinder.By controlling the stretching motion of cylinder, hold tightly realizing brake block
Or releasing of brake drum, thus control whether to carry out the brake of ball mill.Thus, the brake that can effectively carry out ball mill is moved
Make, and this braking mechanism expense is low and can increase brake security.
Under the objective without departing from the basic feature of the present invention, the present invention can be presented as various ways, therefore in the present invention
Embodiment be to be illustrative rather than definitive thereof, owing to the scope of the present invention is defined by the claims rather than limited by description,
