Description
Technical field:
The invention belongs to fine rubber powder screening technique fields, and in particular to a kind of screening cell structure and the centrifugation using it
Sieve.
Background technique:
Rubber grinder is ground the fine glue powder come and is generally 40 mesh or more, this fine glue powder have it is adhesive,
It can be adhered agglomerating, be difficult from conventional linear motion vibrating screen or circular motion vibrating screen screening in the case where calcium powder is not added
It separates, so screening separation must be carried out by existing screen centrifuge.Existing screen centrifuge screening rubber powder is to pass through peace
The symmetrical scraper plate in both sides on main shaft carries out high speed rotation, and the centrifugal force of generation gets rid of rubber powder high speed to sieve, makes
It obtains the fine glue powder that flour mill is produced to enter after the inside process screening of screen centrifuge, qualified thin rubber powder is sieved from sieve
Out, underproof thick rubber powder, which sifts out, is again introduced into flour mill grinding.
The defect of existing screen centrifuge is: since the space between circular screen mesh and main shaft is excessive, so in screening process,
Most rubber powders are all the lower sections for falling in screen centrifuge circular screen mesh, by the rubber powder overwhelming majority that scraper flight moves up all be get rid of to
On sub-fraction arc surface below circular screen mesh, the sub-fraction circle of entire circular screen mesh actually only below is caused
Cambered surface is in screening rubber powder, along with scraper plate quantity is few, so screening efficiency is very low, in addition, the sieve of existing screen centrifuge is easy damage
It is bad to need to be replaced frequently.Its yield of the screen centrifuge of existing 11KW also only has 150 kilograms of hour, is only capable of mating two XJ-280 types mill
The yield of powder machine.
Summary of the invention:
For the technological deficiency for overcoming existing screen centrifuge, the present invention proposes a kind of screening cell structure and the screen centrifuge using it.
The technical solution of the present invention is as follows:
A kind of screening cell structure, including material toggling roller, moving tooth, circular screen mesh, screen frame；Material toggling roller is by material toggling roll shaft and material toggling
Roller outer wall composition；The diameter of circular screen mesh is not more than 4 times of material toggling roller outer diameters.
It is hollow structure between material toggling roll shaft and material toggling roller outer wall, material toggling roll shaft both ends are run through in the screening cell structure
Rotary joint is communicated and is equipped with, for cooling down to water flowing is carried out inside material toggling roller to rubber powder.
In the screening cell structure, the quantity of moving tooth is greater than 4, and on the uniformly distributed and circumference of material toggling roller outer wall.
In the screening cell structure, the linear velocity of moving tooth outermost end is greater than 39m/s.
In the screening cell structure, moving tooth is made of moving tooth outline border and the ultra-fine sieve of moving tooth.
A kind of screen centrifuge includes driving mechanism, feed hopper, thick rubber powder discharge port, thin rubber powder discharge port and the sieve
Locellus mechanism.
The thick rubber powder discharge port of the screen centrifuge installs Blowing stopper.
Beneficial effects of the present invention:
Space between circular screen mesh and roller outer wall is small, and rubber powder can uniformly fall in the external peripheral surface of material toggling roller outer wall,
Then it uniformly being got rid of by a fairly large number of moving tooth to entire circular screen mesh, the whole region of entire circular screen mesh is all sieving rubber powder,
Rather than only the sub-fraction arc surface of circular screen mesh sieves most rubber powders, along with moving tooth quantity increases, moving tooth
Linear velocity improves, therefore moving tooth stirs rubber powder and in the process the movement velocity of rubber powder greatly improved, therefore screening efficiency is significantly
It improves；In addition, moving tooth is made of moving tooth outline border and moving tooth fine screen mesh, although that is, ventilative powder can not pass through, so resistance is significantly
It reduces, reduces installed power；Along with material toggling roll shaft both ends are through communicating and being equipped with rotary joint, for in material toggling roller
Portion carries out water flowing and cools down to rubber powder, so rubber powder temperature is low in screening process, is not easy to be adhered, further be conducive to
Improve screening efficiency.The thick rubber powder discharge port of screen centrifuge installs Blowing stopper, prevents rubber powder is excessive from clean ambient enviroment.
Detailed description of the invention:
Fig. 1 is schematic structural view of the invention
Fig. 2 is A-A cross-sectional view of the present invention
Fig. 3 is the partial enlarged view of moving tooth of the present invention
In attached drawing: 1, motor 2, belt pulley 3, bearing block 4, feed hopper 5, ventilation opening 6, moving tooth are (by moving tooth outline border 6A
With moving tooth ultra-fine sieve 6B composition) 7, material toggling roller (being made of material toggling roller outer wall 7B and material toggling roll shaft 7A) 8, rotary joint 9,
Thick rubber powder discharge port 10, thin rubber powder discharge port 11, Blowing stopper 12, circular screen mesh 13, screen frame
Specific embodiment:
Both ends drilling after material toggling roll shaft is rough turn, drilling depth are more than the limbers at both ends, then weld material toggling roller outer wall
It connects on material toggling roll shaft, after welding, material toggling roller is subjected to rough turn, smart car, the manufacturing procedures such as keyseat, then by several groups
Tooth outline border is uniformly fixed on material toggling roller outer wall (using welding or bolt fastening), is then balanced processing, is then installed
Moving tooth fine screen mesh, finally by entire material toggling roller, other components such as bearing block, sieve, motor, pulley are successively assembled to rack
On.
The course of work:
Start motor 1, by belt pulley 2 drive 7 high speed rotation of material toggling roller, from rubber grinder be ground come rubber powder into
Enter feed hopper 4, on the material toggling roller outer wall 7B uniformly fallen in then into rubber powder sieve inside, while by the moving tooth of high-speed rotation 6
It uniformly gets rid of on entire circular screen mesh 12, thin rubber powder, which is sifted out to be discharged by thin rubber powder discharge port 10, carries out finished product packing.Do not conform to
The thick rubber powder of lattice is fed again into flour mill into material return system out by thick rubber powder discharge port 9 and is ground.8 one end of rotary joint
It is water outlet for the water inlet other end, to carrying out inside material toggling roller, water flowing is cooling, plays cooling rubber powder and further increases screening efficiency
Effect, Blowing stopper 13 play the role of closing wind, prevent from spilling over outside equipment outside the rubber powder inside rubber powder sieve.
