Description of the drawings
Fig. 1 is the structural schematic diagram of preferred embodiment of the present invention.
Specific implementation mode
The present invention is discussed in detail with reference to Fig. 1, illustrative examples of the invention and explanation are used for explaining this herein
Invention, but it is not as a limitation of the invention.
A kind of gap separate grinding machine, including the stator 2 that is arranged in sand cylinder 1 and with the stator 2 with merging by leading
The grinding rotor 4 of the driving rotation of axis 3, described sand cylinder one end are provided with feed inlet 12, are arranged on the outside of the sand cylinder other end
Have and pump 6 by the conveying disperse of the main shaft drives, conveying disperse pump will be delivered to grinding after material dispersion from the feed inlet
In cylinder, material in sand cylinder is after mutually matched grinding rotor and stator mill, separation from being arranged one described in sand cylinder
The discharge port 11 at end flows out.The present invention dexterously utilizes the power drive conveying disperse pump work of main shaft, so as to avoid existing
The form that motor driving conveying disperse pump is individually used in technology, not only saves cost, and the structure of whole system is tighter
It gathers, floor space smaller.
It is formed with gap 5 between the grinding rotor 4 and stator 2 of the present invention, the gap in the sand cylinder to grinding
Material and abrasive media afterwards is detached, and the material after separation is flowed out from the discharge port, to can avoid being arranged specially
Separator detaches material, further saves cost, improves separative efficiency.Previous traditional handicraft is held using mobile
It is delivered to grinder after device transhipment material to be ground, realizes batch production, prepare slurry using conventional hybrid system, need horse
On processing is ground to mixed material, to avoid large granular materials precipitate.Using after this grinder, suspension in production process
More stablize, for material without precipitation, production technology is more flexible reliable, sand mill without clogging, can lifting process reliability and
Production line whole efficiency etc..
Specifically, by material is inputted the sand cylinder after conveying disperse pump dispersion, the grinding rotated in sand cylinder turns
Son and abrasive media material is ground, the gap formed between the stator and grinding rotor to after grinding material and grind
Grinding media is detached, and abrasive media continues to stay in work in sand cylinder, and gap simultaneously carries out thickness separation to the material after grinding,
Thinner material is flowed out from the grinding rotor, is ground again without returning to sand cylinder by the relatively rough material in gap；
Alternatively mode, the material after separation can be flowed out from the main shaft inner cavity；Both forms realize gap separation,
Dynamic centrifugal separation, dynamic discharge, and on the one hand can avoid feed blocking separator, reduce downtime, greatly improve discharging effect
Rate, and then improve production efficiency；On the other hand it avoids setting that special separator is installed, greatly reduces manufacturing cost, and
Easy to operate, process safety is high.
In implementation process, the stator 2 be in hollow form, the stator be set in 4 inner cavity of the grinding rotor and with it is described
Sand cylinder 1 is fixedly connected；Specifically, 4 one end of grinding rotor is mounted in the shaft 3, and the other end forms inner cavity；Stator one
Its inner cavity is inserted in end from the other end described in grinding rotor, and the stator other end is carried out with sand cylinder end cap by bolt etc. affixed；It should
Mode is installed simple, quick, is readily cleaned and safeguards.The number being connected to the bore of stator is offered in the grinding rotor 4
A discharge hole 41 offers material path 42 on the grinding rotor, and the material that material path is flowed into from sand cylinder divides through the gap 5
Entering the inner cavity of stator after being detached from thickness, the thinner material after separation is flowed out from bore of stator through the discharge hole again, and
Sand cylinder is then returned to not over the relatively rough material in gap to be ground again.The gap of the present invention be grinding rotor and stator it
Between formed, since relative motion occurring between the two, material and abrasive media will not block gap, be truly realized big
Flow separation；Meanwhile the thinner material after separation is flowed out from several discharge holes of grinding rotor, is also achieved dynamic centrifugal and is gone out
Material, improves discharging efficiency.
In implementation process, the grinding rotor 4 is equipped with number row's stick pin 43, number row's stick pin phase of cooperation sand cylinder inner wall
Mutual arranged in dislocation cooperation, can be fully ground material, different from the stick pin on the described grinding rotor on grinding rotor
Region is equipped with number and arranges the material path 42, and each material path is connected to the gap, to keep the material after grinding radial
Enter the separation that gap carries out material and abrasive media across material path；The region that the stick pin is right against on the stator is set
There are several sorting holes 21, each sorting hole is connected to the gap and bore of stator；In this way so that material path and sorting hole are staggered
On the one hand setting, the staggered design of this multiple discharge holes, multiple sorting holes, effect can prevent abrasive media such as pick ball
Deng entering bore of stator, on the other hand makes the material after pre-grinding after an intersegmental gap carries out thickness separation, ensure thinner
Material is flowed out from sorting hole.
The present invention each 41 one end of the discharge hole be connected to the discharge port 11 being arranged on sand cylinder, the other end with set
The annular groove 44 set on the grinding rotor communicates, and the annular groove is inserted into the end of the stator.Into the material axis of bore of stator
To its end is moved to, since the annular groove is inserted into the end, it can avoid material and return to sand cylinder from bore of stator, ensure separation
Material afterwards smoothly discharges；Preferably, the end inner cavity that the stator is inserted into annular groove is in horn-like, be conducive to water conservancy diversion, into one
Step improves discharging speed.
Preferably, being equipped with feeding chamber 7 on the outside of the other end described in sand cylinder 1, feeding chamber is connected to the import 71 of material and goes out
Mouth 72, the conveying disperse pump 6 include the pump shafts 62 of the pump leaf 61 being arranged in the feeding chamber and drive pump leaf rotation, the pump
Axis is connect with the main shaft, and in implementation process, the pump shaft can be fixedly connected by axial bolt 63 with main shaft, not only be installed
Convenient disassembly, and reliable transmission.Negative pressure is formed in feeding chamber by the pump leaf of pump shaft driving rotation, to by material from import
Sucking feeding chamber carries out mixing dispersion, then the material after dispersion is delivered to the feed inlet through the outlet, to pass through master
Axis realizes material premixing and conveying with conveying disperse pump, and production cost and equipment input cost is greatly saved, while
Ensure the rationally distributed, compact of grinder.
The above embodiment is used for illustrative purposes only, and is not limitation of the present invention, related technical field
Those of ordinary skill without departing from the spirit and scope of the present invention can be with various changes can be made and modification, therefore institute
There is equivalent technical solution that should also belong to scope of the invention.
