it is further characterized in that: a water pump is arranged above the heat exchange tube, and a water valve is arranged below the cooling liquid tank;

the bottom of the crushing bin is in an inverted trapezoid shape, and a guide plate is arranged inside the inverted trapezoid shape;

and transverse crushing teeth are arranged along the outer side of the main shaft and are conical.

After having adopted such structure, this reducing mechanism moves before, because this reducing mechanism's feed inlet and discharge gate department are equipped with feed valve and bleeder valve respectively, then can make and smash the storehouse and be in encapsulated situation, through locating the outside aerating device of this reducing mechanism, with inert gas fill in smashing the storehouse, the security when this reducing mechanism moves has been guaranteed, after the reducing mechanism moves a period, inside has produced the heat, because it is equipped with spiral helicine cooling tube to smash the storehouse outer wall, and this cooling tube and outside heat exchanger and coolant liquid case intercommunication, then can continuously cool down this reducing mechanism, this reducing mechanism's security has further been guaranteed.

Detailed Description

As shown in figure 1, the insoluble sulfur powder crushing device comprises a crushing bin 1, wherein a feeding hole 2 and a discharging hole 3 are respectively arranged on the side wall and the bottom wall of the crushing bin 1. The crushing bin 1 is internally provided with a containing cavity 7, and sieve holes 711 are uniformly distributed on the side wall 71 of the containing cavity 7. The motor 4 is arranged above the crushing bin 1, and a motor spindle 6 of the motor 4 penetrates through the upper wall of the crushing bin 1 to extend into the accommodating cavity 7 to be connected with the bottom wall of the accommodating cavity. Two crushing shafts 5 are arranged in the accommodating cavity 7, and crushing blades 10 are distributed on the crushing shafts 5 along the axial direction. In order to improve the crushing efficiency of the crushing device, the crushing blades 10 distributed on the two crushing shafts 5 are staggered in the height direction. Further, the bottom wall 72 of the accommodating cavity 7 and the main shaft 6 are respectively provided with a longitudinal crushing tooth 721 and a transverse crushing tooth 61, and the crushing teeth are conical or prismatic, so that the crushing device can comprehensively crush insoluble sulfur when in operation.

An aerating device 16 is arranged above the crushing bin 1, and the interior of the aerating device 16 is filled with inert gas. An air outlet pipe of the air charging device 16 is communicated with the interior of the crushing bin 1. The feed inlet 2 is connected with a material guiding pipe 8 facing the opening of the accommodating cavity 7, the end part of the material guiding pipe 8 is provided with a feed valve 17, and the outlet end of the discharge outlet 3 is provided with a discharge valve 18. Before the operation of the crushing device, the air in the crushing bin 1 is discharged through the air charging device 16 and filled with inert gas. Then the feed valve 17 and the discharge valve 18 are respectively closed, so that the whole crushing bin 1 is in a sealing state. The safety of the crushing device is improved.
