Description

Technical Field

[0001] The utility model relates to the technical field of granulators, in particular to a centrifugal drying and cooling granulator. Background Art

[0002] Centrifugal drying and cooling granulator is an important industrial equipment that can prepare materials into granules with uniform particle size and stable quality. It is widely used in chemical, pharmaceutical, food and other fields. Centrifugal drying and cooling granulator mainly uses the principle of centrifugal force to throw out, dry and granulate wet materials, thereby realizing the processing of materials.

[0003] The centrifugal drying and cooling granulator discharges the material through a discharge pipe after granulation and drying, and then guides it out through a guide plate. The existing guide plate is fixedly installed on the discharge pipe, and the material is not uniform when entering the guide plate through the discharge pipe, which will cause local accumulation of the material on the guide plate, thereby forming a blockage of the guide plate. In addition, the discharged material will have a relatively high temperature, and the material is easy to stick to the guide plate, further causing the blockage of the guide plate, thereby making the discharge efficiency of the centrifugal drying and cooling granulator low when in use. Therefore, improvements are now made to the centrifugal drying and cooling granulator. Utility Model Content

[0006] As a further description of the above technical solution: the vibration component includes a fixed plate fixed on the transmission box body, the fixed plate is fixedly connected to a spring through a support rod, and the top of the spring is connected to a connecting seat arranged on the lower side of the guide plate.

[0007] As a further description of the above technical solution: a connecting shaft is arranged on the guide plate, and a nut is arranged at one end of the connecting shaft through a threaded end, and an axial hole matching with the connecting shaft is opened on the discharge pipe.

[0009] As a further description of the above technical solution: the cooling water pipe is distributed in a serpentine shape along its length direction inside the mounting seat.

[0010] As a further description of the above technical solution: one side of the discharge pipe is provided with a valve plate detachably connected thereto via an insertion interface, and a handle is fixedly mounted on the valve plate.
