Pass through the air quantity of folding control air inlet.
Further, half round table-like housing forms there are two the nozzle covers, is detachably connected between described two housings,
The lower end of the housing is detachably connected with wind shield.Two and half round platform shells are opened when needing to clean nozzle or replaced
Body is operated, and is safeguarded and is closed nozzle cover after completing, then comes into operation, and facilitates the replacement in production to nozzle and dimension
Shield, convenience are good.
Further, the wind shield is flexibly connected with grate granulation operations platform by buckle.
Further, the air regulating board and wind shield are component made of magnesium alloy.
Further, the air regulating board is symmetrical in the bottom end both sides of tower body.
Compared with prior art, beneficial effects of the present invention are as follows：
The volume adjusting apparatus of this granulation tower installs air regulating board to control intake by the air inlet in tower body bottom end, and
Variable frequency adjustment device on the wind turbine of air-out passage is installed and is come further to adjust air quantity or wind turbine suction inlet size is also adjusted
Air quantity is adjusted, in order to avoid there is the situation of positive pressure because of hot-air volume expansion in tower top grate granulation operations platform,
It is granulated on tower top hollow out grate granulation operations platform and wind shield, the top of wind shield, prilling spry has been laid with around nozzle
Upper installation nozzle cover, can effectively avoid the wind speed at nozzle too big, lead to the problem of a large amount of dust, ensure that after installing nozzle cover
Production efficiency reduces environmental pollution.
The volume adjusting apparatus of this granulation tower, by variable frequency adjustment device, wind shield, the setting of air regulating board both can individually make
With, and can be used in combination, realize that the air quantity of granulation tower is adjusted.
Description of the drawings
Fig. 1 is the overall appearance schematic diagram of the present invention；
Fig. 2 is the nozzle cover schematic diagram of the present invention.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
Such as Fig. 1, shown in Fig. 2, a kind of volume adjusting apparatus of granulation tower, including tower body 1, the tower body lower end is equipped with air inlet
