Slot of pelletizing does not have through-hole, effectively prevents the blocking of granulation slot inner via hole, which can efficiently use elastic portion and be pushed away
Pressure, to facilitate the cleaning for realizing the granulation slot blocked, to guarantee anti-clogging effect.
Further, the side wall of cushion chamber has protrusion, which is used to prevent the opposing sidewalls adhesion of cushion chamber.The protrusion
Structure it is more simple, use is more convenient, improve space utilization rate, reduce cost.
Further, through-hole is provided at the gap between adjacent protrusion, cushion chamber is connected to booster cavity by the through-hole.It is logical
The unobstructed of air-flow is realized in the design for crossing through-hole, so that the transmitting of air pressure be effectively ensured, and can effectively be simplified structure and be realized knot
The availability and operability of structure.
Further, hollow in cylinder and be provided with pressure mechanism, pressure mechanism is for squeezing booster cavity.Pressure mechanism is set
Meter, for squeezing booster cavity, by simple Machine Design, realizes the execution of this programme, can guarantee the simple execution of structure,
Structure can be simplified, reduce the cost that equipment is used, repairs and produced.
Further, pressure mechanism includes piston, eccentric wheel and connecting rod, and the side wall sealing of piston and booster cavity cooperates, partially
Heart wheel be eccentric in cylinder and with the same rotational speed of cylinder, piston connect by connecting rod with eccentric wheel；Eccentric wheel pushes when rotating

Slot makes cushion chamber and booster cavity boost, while elastic portion squeezes granulation slot and releases the material particles not fallen off in granulation slot；
Step 2: after cushion chamber and booster cavity boost to 30-45pa, piston is gradually distance from granulation slot and makes cushion chamber and increasing
Chamber decompression is pressed, after cushion chamber and booster cavity are depressurized to -60~-80pa, piston is again adjacent to granulation slot, until booster cavity boosts
To standard atmospheric pressure, slot of then pelletizing carries out secondary extrusion granulation.
This uses the method for piston, is capable of increasing the shift motion of piston, thus increase the boost or depressurization of booster cavity
The upper limit or lower limit guarantee anticlogging feasibility to effectively guarantee the pop-up of elastic portion.
Further, obstruction-proof method are as follows:
Under the elastic force effect of seal closure, booster cavity is under the negative pressure state in -10~-20pa always, works as granulation
After the completion of slot squeezes granulation, for the granulation slot with barrel body rotation to designated position, the extruding wheel that the designated position is arranged in squeezes system
Grain slot makes booster cavity boost to 10-15pa, and in booster cavity boost process, elastic portion deforms and releases remaining object in granulation slot
Expect particle；After slot of pelletizing is detached from the designated position, booster cavity reverts to negative pressure state under the elastic force effect of seal closure.
This method, structure are conducive to the replacement of structure, while being also able to achieve granulation using simple, easy to repair and operation
The anticlogging effect of slot.
Further, it is followed successively by base, high-temperature-resistant layer and non-sticking lining from the inside to the outside on the side wall of granulation slot；High temperature resistant
Layer is made of the material of following parts by weight: 35 parts of tungsten carbides, 6 parts of silica, 4 parts of quartz, 7 parts of aluminum oxides, 9 parts of carbonizations
