Description
Technical field:
The utility model relates to a kind of reducing mechanism, the explosion-proof pulverizer of especially a kind of two coolings.
Background technology:
In chemical process, often to pulverize processing to some materials, but under many circumstances, crushing process is abnormally dangerous, as: the temperature rise in the crushing process is very easily blasted some material, and the lower product of fusing point is often too high because of temperature rise in the high speed crushing process, makes material melt and can't process.At present, domestic also do not have a kind of disintegrating apparatus that can address the above problem.
The utility model content:
The utility model provides a kind of two coolings explosion-proof pulverizer, and it is simple in structure, has reduced the temperature in the crushing process, has avoided blast, has improved the security of pulverizing processing, has guaranteed normally carrying out of crushed work, has solved problems of the prior art.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: it comprises casing, be provided with crushing chamber in casing inside, the charging aperture on crushing chamber top links to each other with feed pipe, the rotating shaft that stretches out the casing outside in the output shaft of motor and the crushing chamber links to each other, evenly be provided with three grades of pulverizing cuttves on the rotating shaft, be provided with cooling jacket between casing and crushing chamber, the cooling jacket bottom is provided with cold liquid import, and top is provided with cold liquid outlet; Be provided with the air inducing chamber along flow direction of material at the rear portion of crushing chamber, the air inducing blade that is arranged in the air inducing chamber evenly is connected on the rotating shaft, and air inducing chamber one end links to each other with powder outlet; On feed pipe, be connected with nitrogen tube.
The utility model is simple in structure, employing is provided with cooling jacket between casing and crushing chamber, add in pulverizing to feed cooling fluid man-hour in cooling jacket, has reduced the temperature of comminuting matter, avoid the too high explosion danger that brings of temperature, improved the security of pulverizing processing; On feed pipe, connect nitrogen tube, at the rear portion of crushing chamber the air inducing chamber is set along flow direction of material, air inducing blade rotation in the air inducing chamber produces suction, low temperature nitrogen in the nitrogen tube is introduced crushing chamber through feed pipe, charging aperture, material is pulverized under the low temperature nitrogen environment, has guaranteed the security of pulverizing, and low temperature strengthens material fragility simultaneously, be easier to pulverize, working (machining) efficiency is greatly improved.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1, casing; 2, crushing chamber; 3, charging aperture; 4, feed pipe; 5, motor; 6, rotating shaft; 7, pulverize cutter; 8, cooling jacket; 9, cold liquid import; 10, cold liquid outlet; 11, air inducing chamber; 12, air inducing blade; 13, powder outlet; 14, nitrogen tube.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in FIG., the utility model comprises casing 1, be provided with crushing chamber 2 in casing 1 inside, the charging aperture 3 on crushing chamber 2 tops links to each other with feed pipe 4, the rotating shaft 6 that stretches out casing 1 outside in the output shaft of motor 5 and the crushing chamber 2 links to each other, and evenly is provided with three grades of pulverizing cuttves 7 on the rotating shaft 6, is provided with cooling jacket 8 between casing 1 and crushing chamber 2, cooling jacket 8 bottoms are provided with cold liquid import 9, and top is provided with cold liquid outlet 10; Be provided with air inducing chamber 11 along flow direction of material at the rear portion of crushing chamber 2, the air inducing blade 12 that is arranged in the air inducing chamber 11 evenly is connected on the rotating shaft 6, and air inducing chamber 11 1 ends link to each other with powder outlet 13; On feed pipe 4, be connected with nitrogen tube 14.
During work, start motor 5, motor 5 drives by rotating shaft 6 and pulverizes cutter 7 and 12 rotations of air inducing blade, open coolant valve, cooling fluid is entered in the cooling jacket 8 through cold liquid import 9, and cooling fluid can be used chilled brine or phreatic water, opens the nitrogen valve, the suction that air inducing blade 12 rotations in the air inducing chamber 11 produce is introduced nitrogen in the crushing chamber 2 through feed pipe 4, charging aperture 3, and crushing chamber 2 is in low-temperature condition under the effect of cooling jacket 8 and low temperature nitrogen.At this moment, evenly add materials by charger from feed pipe 4, material enters in the crushing chamber 2, pulverizes the back through three grades of pulverizing cuttves 7 and is blown out pulverizer by the air inducing blade 12 at rear through powder outlet 13, collects the laggard feed bin of going into through cyclone separator.Because pulverizer is in cooling of inner cryogenic nitrogen and external refrigeration chuck 8 coolings work down, long-play also can not generate heat, and has guaranteed the security of pulverizer operation, and because low temperature, material fragility strengthens, and its easier quilt is pulverized, and working (machining) efficiency is greatly improved.
The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
