Description
Technical field
This utility model relates to a kind of sand mill.
Background technology
At present, the sand mill used in industry is mostly disc type, rod pin, and its ultimate principle is: in envelope
The cylinder closed is built with medium such as zirconium pearl, the bead etc. for grinding, by the rotating disk being arranged in rotating shaft
Or rod pin stirs the medium in cylinder, make medium produce relative motion, allow the required material ground through medium
Between with reach pulverize effect.Abrasive media relative velocity is the highest, and impact force is the biggest, and fineness of grind is just
The best；The effect that disc type, the model of action of rod pin-type sand mill make abrasive media perform relative motion not is very
Ideal, so the fineness of materials being ground is extremely difficult to nanoscale.
At present, the application improving grinding efficiency and abrasive product precision and developing sand mill is sand mill
Research direction.Traditional sand mill generally comprise inside form grinding chamber sand cylinder and with this grinding chamber
The feed cavity of connection, described grinding chamber two ends are respectively by end cap seal, and grinding spindle is stretched through an end cap
Enter in grinding chamber, in this grinding chamber, be provided with the grinding rotor being rotated by grinding spindle.Separator is arranged on
On grinding spindle, from the discharging of grinding spindle axle center；Or separator is arranged on grinding spindle, seal method from machine
Discharging at blue seat.
But, in use, separator is the most blocked for the sand mill of said structure, now, needs to remove
Dispersion turbine on whole grinding cavity, and attached various pipe fittings (cold water pipeline) and grinding spindle,
Maintenance time is long and can waste more material.
Utility model content

Change and describe rather than indicate or imply that the device of indication or element must have specific orientation, with specifically
Azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.In description of the present utility model
In, except as otherwise noted, " multiple " are meant that two or more.
In description of the present utility model, it should be noted that unless otherwise clearly defined and limited, art
Language " is installed ", " setting ", " connection " should be interpreted broadly, and connects for example, it may be fixing, it is also possible to
It is to removably connect, or is integrally connected；Can be to be joined directly together, it is also possible to by the indirect phase of intermediary
Even.For the ordinary skill in the art, can understand that above-mentioned term is new in this practicality with concrete condition
Concrete meaning in type.
Fig. 1 shows the structure of the sand mill that this utility model preferred implementation provides.
Concrete, this sand mill include grinding pot 1, end cap 2, separator 4, feed pipe 7, discharge nozzle 8,
Air inlet pipe 9, piezometer 10 and thermometer 11.
Grinding pot 1 is cylindrical barrel body, its inner hollow.End cap 2 is fixed on grinding pot 1 end.End cap 2
Combine with grinding pot 1 in grinding pot 1, form grinding chamber 3.
Grinding spindle (not shown) extends in grinding chamber 3 from grinding pot 1 one end, for grinding
Material in chamber 3 is ground.
Feed pipe 7 is communicated to grinding chamber 3 by body 6, forms feeding-passage.
Concrete, feed pipe 7 is provided with check valve, and check valve can realize the through of feeding-passage or disconnect.
Body 6 in feeding-passage is tee T, and one the mouth of pipe is connected with feed pipe 7 by fast card 12,
Another mouth of pipe is connected with the piezometer 10 of pressure in monitoring grinding chamber 3 by fast card 12, last
The individual mouth of pipe is connected on grinding pot 1 by fast card 12, and is communicated in grinding chamber 3.
In present embodiment, separator 4 is arranged in end cap 2 outside end cap 2, and extends to grinding chamber 3
In.Separator 4 is connected by flange is fixing with the lateral surface of end cap 2.Set between separator 4 and end cap 2
It is equipped with sealing ring, to realize being tightly connected between separator 4 and end cap 2.
Separator 4 includes screen cloth gland, screen base, multiple video disc and trip bolt.Screen cloth gland and sieve
Net pedestal is positioned at grinding chamber 3, and interfixes.Screen cloth gland is located remotely from the side of end cap 2.Multiple
Video disc is sequentially stacked along the direction from screen cloth gland to screen base；It is provided with pad between adjacent two video discs
Sheet.By pad by spaced apart for two adjacent video discs.Trip bolt sequentially passes through described screen cloth gland and dish
Sheet, fixes described screen cloth gland and video disc with screen base.
Above-mentioned screen cloth gland, screen base and video disc are ceramic material, such as, can use conventional oxidation
Zircon ceramic.
Discharge nozzle 8 is communicated to described separator 4 by body 6, is formed and connects from the separated device of grinding chamber 34
Tapping channel to discharge nozzle 8.
On discharge nozzle 8, there is ball valve.
The body 6 of tapping channel uses tee T equally, and one the mouth of pipe is by fast card 12 with discharge nozzle 8 even
Logical, another mouth of pipe is connected with the thermometer 11 of temperature in measuring discharge nozzle 8 road by fast card 12,
Last mouth of pipe is communicated to separator 4.
Meanwhile, the body 6 of above-mentioned tapping channel being additionally provided with air inlet pipe 9, the body 6 of tapping channel can pass through
Air inlet pipe 9 is communicated to high-pressure air source, so that the compressed air of high-pressure air source can be led to through air inlet pipe 9 and discharging
The body 6 in road flows into separator 4.
There is in above-mentioned air inlet pipe 9 ball valve controlling its break-make.
When normally using, the check valve of feed pipe 7 is opened, and the ball valve in air inlet pipe 9 is closed, discharge nozzle 8
Ball valve open, the separated device of slurry 4 in grinding chamber 3 from tapping channel flow out.Fortune along with sand mill
OK, slurry is gradually in the blocking accumulation of separator 4 surface, thus forms slurry crust 5 on separator 4 surface,
Wrap separator 4.
When above-mentioned slurry crust 5 occurs, it is possible to find grinding chamber 3 pressure quickly raises that (piezometer 10 shows for it
Number), maintain higher level, the discharging flow of discharge nozzle 8 significantly reduces, and even causes equipment grinding chamber 3
Pressure protection is reported to the police.Now, close the check valve of feed pipe 7, stop charging, treat what piezometer 10 detected
When pressure in grinding chamber 3 is less than certain value, closes the ball valve of discharge nozzle 8, and open rapidly air inlet pipe 9
Ball valve some seconds (being adjusted according to practical situation, pressure not can exceed that the sand mill the highest pressure-bearing upper limit),
It is then turned on the ball valve of discharge nozzle 8, simultaneously closes off the ball valve of air inlet pipe 9.Use pressure-air to separator 4
The slurry crust 5 on surface purges, and slurry crust 5 is thoroughly smashed dispersion.The most several times,
In can accomplishing several minutes, slurry crust 5 is removed from separator 4 surface, it is to avoid separate device 4 block clearing
Maintenance.It is greatly saved manpower and materials, the shortest, avoid the waste of material simultaneously.
Further, when necessary, separator 4 need to be dismantled when clearing up and keep in repair, only need to directly will divide
Unload from end cap 2 from device 4, it is not necessary to dismounting miscellaneous part, enormously simplify operation, shorten dimension
Repair the time.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model,
All any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, all should
Within being included in protection domain of the present utility model.
