Abstract

The utility model relates to a roller pressing type particle making machine, which is particularly suitable for the granulated production of the complex fertilizer. The machine is provided with two rollers with relative rotation; the outer wall of each roller is provided with corresponding concave dies with uniform distribution; the two roller have a certain gap distance, and the raw material entering the concave dies is extruded into an oval shape; the raw material between each concave die is extruded into a lamellar shape; the oval and the lamellar extruding products are linked into a sheet and disengage from the rollers simultaneously. The die disengaging rate reaches 95%. An extruding opening and a receiving plate have a relatively great distance, and the lamellar position crushes into single spherulite after the extruding products are knocked when falling freely. The utility model has the advantages of simple structure, easy installation, convenient maintenance, floor occupation saving, high die disengaging rate, etc.

Description

The utility model is a kind of roller press type Granulation Equipments, is specially adapted to the granulating production of composite fertilizer.
Existing granulation of compound fertilizer is with its processing technology different main divide rolling granulation or compression granulations.The rolling granulation is because of existing operation many, and equipment investment is big, and occupied ground is many, and drawbacks such as consumes energy and loss raw material; And the compression granulation is based on roll-forming, but in the roll-forming because particle demoulding difficulty, therefore, people pay attention to the research to the mould emptier of roll-in granulation, as:
CN85202155u
CN89206355.6
CN87106563A
Be in running roller, to set up auxiliary body in addition, as:
CN87210481u
Analysis by above-mentioned each documents and materials, though the release problems of roll-in granulation can be resolved, but it is complicated that the structure that makes equipment becomes, increase processing, assembly difficulty and cost of investment, again because the corrosion to equipment is bigger in composite fertilizer's granulating production process, therefore, Fu Za structure increases difficulty for maintenance, maintenance.
The purpose of this utility model is that a kind of pair roller that adopts of design pushes, and is suitable for and satisfies the roller press type comminutor of compound fertilizer production requirement.
Roller press type comminutor of the present utility model has two counterrotating running rollers is installed on support and the support, and uniform and corresponding die is arranged on the outer wall of each running roller, and the clearance distance of two running rollers is 0.1~1mm.
Roller press type comminutor of the present utility model, its running roller center line is more than the 200mm with the distance H of the plate that connects material.
Roller press type comminutor of the present utility model, its rolling axle is made by carbon steel material, stainless steel sleeve on the outer wall liner of axle, die is on stainless steel sleeve.
Roller press type comminutor of the present utility model, the die on this running roller is elliposoidal half, and the die bore is 3~8mm, is 0.8~2.5mm deeply.
Roller press type comminutor of the present utility model has the micro-adjusting mechanism of two running rollers at the axle head of running roller, and is corresponding to guarantee die.
Roller type comminutor of the present utility model; relative rotation with two running rollers; the raw material that drops into is pushed; because there is the gap in two running rollers; its raw material that enters in the die is squeezed into elliposoidal; raw material between each die is squeezed into laminar, and elliposoidal and laminar extrudate are linked to be sheet and break away from running roller simultaneously, and demolding rate reaches 95%.Be linked to be in the extrudate of sheet, its elliposoidal because wall thickness is difficult for broken; And the wall of extruding between each die is thin, is subjected to force intensity low, leaves the running roller compressive plane and after being subjected to gravity and stretching, will disconnect voluntarily.So extrudate also can large stretch ofly not link to each other neither single spheroid, but several to tens fall in flakes.Extrusion because of its plate that connects material (can be receiver, conveyer belt) and two running rollers differs certain distance again, therefore, the extrudate of falling the plate that connects material is subjected to becoming single spheroid basically after the impact, and also surplus a small amount of mutual squeezing that be subjected to when packing in flakes wiped, and all becomes single spheroid.Again because the distance between each die very little (about 0.3~0.5mm), so become the edge of ellipsoid after this part extrudate fragmentation, can not fragmentate certainly, become the pulverulent minimum ratio that also only accounts for.Granulating goods of the present utility model are through examination, and every technical-economic index meets composite fertilizer's requirement.And it is simple to have a device structure, and installation, maintenance is convenient, and occupied ground is few, characteristics such as demolding rate height.
Fig. 1 is that the utility model roller press type comminutor drive connection connects schematic diagram;
Fig. 2 is the utility model roller press type comminutor two running rollers extruding schematic diagram;
Fig. 3 is the utility model roller press type comminutor running roller structural representation.
Below in conjunction with accompanying drawing 1-3 embodiment of the present utility model is elaborated.
1, active roll; 2, passive running roller; 3, die; 4, two running roller gaps; 5, bearing block; 6, bearing; 7, roll-in synchromesh gear; 8, running roller gap micro-adjusting mechanism; 9, gland; 10, shaft coupling; 11, gearbox; 12, feed hopper; 13, running roller center line; 14, the plate that connects material; 15, rolling axle; 16, stainless steel sleeve.
Roller press type comminutor of the present utility model; active roll (1) and passive running roller (2) are installed on support; uniform and corresponding die (3) is arranged on two running roller outer walls; rolling axle matches with bearing (6); roll-in synchromesh gear (7) is installed in outer end near bearing block (5); at the axle head of driven pulley (2) micro-adjusting mechanism (8) of running roller is arranged, the drive roll wheel shaft is connected with speed-changing gear box (11) by shaft coupling (10).When the raw material in the feed hopper (12) flow to be extruded between two running rollers after, freely fall the plate that connects material (14), extrusion (being equivalent to the running roller center line) to the distance H of the plate that connects material is about 500mm.The burn into wearing and tearing of producing middle roll in granulation are all more serious, so rolling axle (15) is made by carbon steel material, stainless steel sleeve on the outer wall liner (16) both reduced cost, and was convenient to maintenance again.
