Abstract
The invention discloses a ring membrane granulator. A press roller is fixed by a press roll shaft installed in a casing, the press roll shaft is installed in a casing through a bearing, and one end of the shaft extends out of the casing and is connected with the press roller through a flat key. The inside of the casing has a circulating cooling medium to cool the bearing, and a temperature sensor is arranged in the casing; when a temperature from the feedback of the temperature sensor reaches the set temperature, the circulating cooling system starts so as to cool the bearing and the press roll shaft, therefore, the bearing is allowed to work below the set safety temperature, and the service life of the bearing is extended. The ring membrane granulator has the advantages that instead of being installed in the press roller originally, the bearing is installed in the casing outside the press roller through the press roll shaft, the circulating cooling medium is arranged in the casing to cool the bearing and the press roll shaft, and the problem that the bearing is prone to overheat and damage due to the poor cooling is solved.
Description
Technical field：
The present invention relates to agricultural technology field, be specifically related to a kind of ring film with agricultural biomass discarded object as raw material and pelletize
Machine.
Background technology：
The main granulation mode of current granulator has the several ways such as spiral squeezing type, piston punching type, ring film squash type,
Being most commonly that ring film squash type granulator, this granulator is to arrange two pressure rollers in ring film, by the rotating band of ring film
Dynamic two pressure rollers rotate, and form wedge shaped squeeze space between ring film and pressure roller, relatively rotate drive by ring film and pressure roller
Material is constantly squeezed into ring film fenestra, is extruded by fenestra material, expands, is cut off, completes pelletization.By then passing through
Forcing extruding to complete granulation, so in the course of the work, granulator can produce substantial amounts of heat, gives bearing inside pressure roller
Lubrication brings very burden, and lubricating oil is quickly fallen by high temperature evaporation, will damage with not long-time bearing so that ring film is pelletized
Bearing in confidential frequent replacing pressure roller, produces and therefore suffers from impact.To this end, we devise a kind of ring film granulator, pressure
The bearing of roller is put into and is lubricated in the pressure roller shaft of outside, installs pressure roller by a pressure roller shaft, and pressure roller is by key and pressure roller
Axle couples, and so can effectively reduce the operating temperature of roller bearing, extends the life-span of bearing and the use time of machine.
Content of the invention：
The technical problem to be solved is to reduce the temperature of roller bearing, extends the service life of roller bearing,
Thus improve the efficiency of ring film granulator.
The present invention is realized in：Pressure roller is to be fixed by the pressure roller shaft being arranged in casing, and pressure roller shaft is logical
Crossing bearing to be arranged in casing, one end of this axle is stretched out outside casing and pressure roller passes through Flat dey joint, has the cold of circulation in casing
But bearing is cooled down by medium, is provided with temperature sensor in casing, and the temperature returned when temperature sensor feedback reaches to set
During numerical value, circulating cooling system starts, and cools down bearing, pressure roller shaft, makes bearing be maintained at below the safe temperature of setting
Work, extends the service life of bearing.
It is an advantage of the invention that：The casing being originally arranged on bearing inside pressure roller and being arranged on by pressure roller shaft outside
In, it in casing, is provided with circulating cooling medium pressure roller shaft and bearing are cooled down, this addresses the problem because bearing cooling is bad
The easily overheated and problem damaged.Cooling medium in casing can be cooling oil, circulation compressed air, can also be cold with circulation
But water cools down oil, and oil cools down pressure roller shaft and bearing again.
Brief description：Fig. 1 is the structural representation of the present invention；
In figure：Ring film 1, pressure roller 2, pressure roller shaft 3, casing 4, bearing 5, bearing 6, cooling medium inlet 7, cooling medium exports
8, cooling medium 9, temperature sensor 10, key 11, cooling medium circulation system 12.
Detailed description of the invention
It as it can be seen, the present invention has a casing 4, in casing, is provided with bearing block bearing 5 and bearing 6, pressure roller shaft 3 are installed
Being arranged on casing 4 by bearing 5 and bearing 6, one end of pressure roller shaft 3 couples pressure roller 2 by key 11.There is cooling in casing 4
Medium 9, cooling medium 9 exports 8 by cooling medium inlet 7 and cooling medium and cools down in cooling medium circulation system 12
Circulation.During work, ring film 1 rotational band dynamic pressure roller 2 rotates, and in the wedge shape space that ring film 1 and pressure roller 2 are formed, material is constantly ground
Pressure, by the fenestra shaping of ring film, due to powerful grinding pressure, during work, ring film, pressure roller and material all produce very big heat,
The heat of pressure roller passes to bearing by pressure roller shaft, and the heat of bearing is followed in the cooling of cooling recirculation system 12 by cooling medium 9
It is pulled away under ring, if it occur that the heat that cooling medium 9 is taken away raises less than bearing the 5th, 6 heat obtaining, bearing the 5th, 6 temperature
When, this temperature passes to switch board by temperature sensor 10, when temperature reaches to set numerical value, stops granulation work, treats temperature
It is reduced to during safety value restart ring film to pelletize, thus protect the damage that bearing causes because of overheated.
