Embodiment Construction

[0014] Below in conjunction with accompanying drawing, specific embodiment is described:

[0015] Such as figure 1 , figure 2 and image 3 As shown, a tower type granulation device includes a housing 1, an outer shaft 2 is installed inside the housing 1 through a bearing, the top end of the outer shaft 2 is connected with an outer shaft driven gear 21, and the bottom end is connected with a Rotating impeller 22; the outer rotating shaft 2 is a hollow cylinder, and a coaxial inner rotating shaft 3 is installed inside it through a bearing. The top end of the inner rotating shaft 3 is connected with an inner rotating shaft driven gear 31, and the bottom end is connected with a nozzle housing 6. The outer contour surface of the nozzle housing 6 has several small holes 61, and the rotating impeller 22 is located inside the nozzle housing 6, leaving a certain gap between the two; a motor 4 is installed on the top of the housing, and the motor The output shaft of 4 extends into t...

Abstract

The invention discloses a towered granulating device, comprising a housing which is provided with an electric motor, wherein, an internal rotating shaft and an external rotating shaft which are arranged inside the housing are driven by the electric motor to rotate in opposite directions with the gear wheel transmission way. The reverse direction rotation drives a rotating impeller and a nozzle housing which are arranged at the bottoms of the internal rotating shaft and the external rotating shaft to rotate in opposite directions, thereby ensuring that the solution positioned inside the nozzle housing is thrown out from holes of the nozzle housing and enters a cooling medium in a liquid dropping way; the rotating speed is adjusted simply by replacing speed adjusting gear wheels with different diameters through the design of engagement of the speed adjusting gear wheels, a driven gear wheel of the internal rotating shaft and a driving gear wheel of the internal rotating shaft, thereby being convenient to change the speed; one electric motor is adopted to drive the rotating impeller and the nozzle to rotate in opposite directions, and the gear wheel transmission way is adopted, thereby the energy consumption is reduced; a cross section and a lengthwise section inside the nozzle housing are provided with holes forming certain angles with the nozzle external wall, thereby reducing the dust rate when the solution is thrown out and the particles are made and solving the problem of jet hole blockage.

Description

technical field [0001] The invention relates to fertilizer manufacturing equipment, in particular to a tower type granulation device. Background technique [0002] At present, the high-tower granulation device is mainly a differential double-speed rotary granulation structure. This structure adopts two independent rotary mechanisms on the same axis. The internal rotary mechanism drives the granulation nozzle, and the external rotary mechanism drives the distributor. The two rotating mechanisms work on the same axis, and the process of the melt from the inside of the tower to the spray nozzle is completed by adjusting their respective speeds and directions; at present, this device has a large power consumption, difficult to adjust the speed, and a partial dust rate High, the nozzle hole is clogged. [0003] At the same time, the nozzles of the high-tower granulation and granulation equipment used to produce compound fertilizers are all nozzle cone parts of the urea or ammoni...
