Detailed Description
As shown in the attached drawing, the granulating device for the fertilizer comprises a shell 1, a feed hopper arranged at the upper part of the shell 1, a pair of granulating press rolls 3 arranged at the middle part of the shell 1 and a crushed material returning mechanism arranged at the lower part of the shell 1;
the shell 1 is of a rectangular box-shaped structure, the feed hopper comprises an upper groove-shaped hopper 21, a middle square hopper 22 and a lower groove-shaped hopper 23 which are integrally formed, hopper grooves of the upper groove-shaped hopper 21 and the lower groove-shaped hopper 23 are both of a trapezoidal structure, a fertilizer feed pipe 9 is arranged above the upper groove-shaped hopper 21, a group of crushing rollers 24 is further arranged in the middle square hopper 22, a first filter screen plate 25 is arranged below the group of crushing rollers 24, and a pair of connecting plates 26 connected with the inner wall of the shell 1 is arranged at the bottom of the lower groove-shaped hopper 23;
a pair of granulation compression rollers 3 is arranged below the lower groove-shaped hopper 23, cleaning brushes 4 are respectively arranged on the two sides of the pair of granulation compression rollers 3 and on the inner wall of the shell 1, and bristles of the cleaning brushes 4 are abutted to roller bodies of the pair of granulation compression rollers 3; a second filter screen plate 27 is obliquely arranged below the pair of granulation press rollers 3, and a granulation outlet part 5 is arranged at the joint of the lower end of the second filter screen plate 27 and the shell 1;
the crushed material returning mechanism comprises a crushed material guide plate 6 obliquely arranged below the second filter screen plate 27, a returning pipe 7 and a returning pump 8 arranged on the returning pipe 7, one end of the returning pipe 7 is connected to the joint of the lower end of the crushed material guide plate 6 and the shell 1, and the other end of the returning pipe extends into the upper groove-shaped hopper 21.
The top of feeder hopper is equipped with and is equipped with its confined apron 30, sets up the hole that supplies fertilizer inlet pipe 9 and return pipe 7 to stretch into on the apron 30.
A set of crusher rolls 24 are rotated by a set of first motors mounted to the upper outer wall of the housing 1.
The length of the middle square hopper 22 is the same as that of the shell 1, and the width of the middle square hopper 22 is one half of that of the shell 1.
The pair of granulation rollers 3 is driven to rotate by a pair of second motors installed on the outer wall of the middle part of the housing 1.
