Abstract
The invention relates to a method for emptying from a ball mill through pressurizing by a wet process and a device. The device comprises an air compressor (1), an air storage tank (2), a bottom valve (6) and an air distribution valve (5). In the process of grinding, the bottom valve is locked; when emptying is needed, the bottom valve is opened and the air distribution valve is installed to introduce the high pressure air (0.2-0.4mpa) in the air storage tank into the ball mill via an air delivery pipe, and an emptying hole is opened for emptying; and the materials are rapidly discharged from the emptying hole under own gravity and the action of extrusion of the air pressure in a grinding cylinder, and the residual materials are intermittently discharged. The invention has the beneficial effects of speeding up emptying, fully and completely discharging the materials in the grinding cylinder of the ball mill and having simple structure and small investment.
Description
Technical field
The present invention relates to a kind of method and device of ball mill by wet process processing materials.
Background technology
At present, wet ball grinding technology is extensively utilization in industrial production, and its principle is material, water to be added ball mill in proportion grind, and emits from tapping hole after reaching stipulated time or granularity.Usually the character of material has adhesion, if the concentration of slip is bigger, material then is easy to be adsorbed between the slit of the surface of abrasive media and abrasive media, causes material not emit fully, thereby influences subsequent operation.Also there are a lot of producers to use, attempt material is taken out to the greatest extent by the suction of pump at the tapping hole slush pump, but DeGrain.
Summary of the invention
Purpose of the present invention is exactly that the blowing that wet ball grinding exists is slow, material sticks, material is put unclean shortcoming, a kind of pressurization discharging method and the device that provide in order to overcome.
The present invention at first provides a kind of pressurization discharging method: gases at high pressure (0.2-0.4mpa) are introduced ball mill, open the tapping hole blowing, material flows out from tapping hole rapidly under the effect of squeezing of high pressure air pressure in self gravitation and the sand cylinder, and residual material is also discharged by batch (-type).
The present invention also provides a kind of pressurization discharging device: it is made up of air compressor machine, air accumulator and bottom valve and distributing valve, is provided with bottom valve, distributing valve on ball mill charging aperture lid, and the distributing valve order links to each other with air accumulator to the distributing valve fast joint.In process of lapping, bottom valve closes; When needing blowing, bottom valve is opened, loaded onto distributing valve and distributing valve, the gas of air accumulator is introduced ball mill, open the tapping hole blowing by appendix.Material flows out from tapping hole rapidly under the effect of squeezing of air pressure in self gravitation and the sand cylinder, and residual material is also discharged by batch (-type).
The invention has the beneficial effects as follows, accelerate dispensing speed, and can be fully, completely the material in the ball mill grinding tube is discharged, simple in structure, invest little.
The present invention is further described below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is the system diagram of emptying from ball mill device among the present invention;
Fig. 2 is the vertical section structure figure of the bottom valve in the emptying from ball mill device;
Fig. 3 is the structure chart that bottom valve in the emptying from ball mill device and distributing valve are used.
Embodiment:
Emptying from ball mill device provided by the invention and system thereof form as shown in Figure 1, and it is made up of air compressor machine 1, air accumulator 2 and bottom valve 6 and distributing valve 5, and air accumulator 2 links to each other with distributing valve 5 by tracheae 4, and two pressure-reducing valves 3 also are set in tracheae.As shown in Figure 2, on the charging aperture lid of ball mill 7, be provided with bottom valve 6, the center of bottom valve 6 be provided with screw and the closed spiro rod 9 that matches with bottom valve 6 sealings, bottom valve 6 tops are provided with external screw thread 6a.As shown in Figure 3, when after ball milling finishes, needing blowing, then unload closed spiro rod 9, load onto distributing valve 5, it is connected cooperation with the external screw thread on bottom valve 6 tops, distributing valve 5 tops are provided with the hole that communicates with the bottom valve center screw, and this hole is connected to fast joint 10 with distributing valve top and communicates, and 4 of tracheaes are connected in the fast joint 10.
Discharging method provided by the invention is as follows:
In process of lapping, bottom valve is closed with closed spiro rod 9; When needing blowing, closed spiro rod in the bottom valve is unloaded, load onto distributing valve, by tracheae the gases at high pressure of air accumulator are introduced ball mill, open baiting valve 8, material flows out from tapping hole rapidly under the effect of squeezing of air pressure in self gravitation and the sand cylinder, after blowing finishes for the first time, stop ventilation, close baiting valve 8; After 15 minutes, repeat above-mentioned steps, material in the grinding cylinder can be put only.
Equipment and technological parameter that present embodiment adopts are as follows:
1, equipment adopts 5 tons of ball mills of φ 2m * 4m, the air accumulator of 10m3;
2, technological parameter: 3 tons of zircon sands, 2 tons of water grind 12 hours (about granularity 1.8 μ m).Grinding the pressure of importing when finishing blowing is 0.2-0.4Mpa.
3, result: the pressurization blowing, 40 minutes consuming time, material emitted 95%, and the blowing flow velocity is fast.And natural blowing, 80 minutes then consuming time, material emitted 70%.
The method also has an obvious advantage: the discharging opening that must guarantee pipeline during natural blowing is lower than the height (minimum be discharging opening) of liquid level in the ball mill, and method of the present invention can be forced into material than ball mill discharging mouth high horizontal level (stock tank) also
