Summary of the invention
In order to solve existing in prior technology the problems referred to above, the invention provides a kind of pulverizer, it can increase from the suction of the outside suction of discharging opening, avoids screen cloth to stop up the fault that is caused, thereby improves output and the speed of pulverizing discharging.
Technical scheme of the present invention is to constitute like this, it comprises the material pulverizing chamber, the pulverizing chamber top is provided with charging aperture, the pulverizing chamber inner chamber be provided with the main shaft that drive to rotate by power-equipment and can be in perpendicular to the plane of main-shaft axis by the crushing knife tool of main shaft driven rotary, have at least an end to be provided with discharging opening in the axial two ends of pulverizing chamber, discharging opening is provided with screen cloth, it is characterized in that: the periphery of described pulverizing chamber also is provided with the wind sucting chamber that is connected with discharging opening, the exit of wind sucting chamber connects air-introduced machine, and the line shaft of air-introduced machine is not connected transmission with main shaft.
Than prior art, the beneficial effect of technique scheme of the present invention is as follows: 1. owing to set up wind sucting chamber in the pulverizing chamber periphery, and air-introduced machine is located at the outlet of wind sucting chamber, therefore, during work, can start air-introduced machine earlier, the vacuum that produces by the air-introduced machine rotation is taken away the air in the wind sucting chamber in a large number, form low pressure in the wind sucting chamber, afterwards when main shaft is worked, the very big outside suction of generation naturally under the low pressure effect of the normal barometric pressure of charging aperture and wind sucting chamber of the material in the pulverizing chamber, thereby material is easily from the discharging opening sucking-off, and can not stop up the mesh of screen cloth, therefore not only can improve discharging speed greatly, reduce consumed power, and ingredient requirement is reduced, the water content of processing materials can improve (generally can bring up to less than 20%), has enlarged the range of work.2. because the line shaft of air-introduced machine is not connected transmission with main shaft, when screen cloth is blocked, but air-introduced machine is normal rotation still, air airtight in the wind sucting chamber almost forms vacuum after constantly being drawn out of, at this moment, the powerful outside suction that discharging opening is produced can force the material that stops up screen cloth to be sucked out, thereby recovers normal crushed work.3. owing to can guarantee to pulverize normally processing work, material can not accumulate in for a long time and cause heating in the pulverizing chamber and the change performance, owing to arriving air-introduced machine (outlet of wind sucting chamber) from discharging opening, material to pass through the stretch journey in addition, temperature of charge after the pulverizing is reduced rapidly, can not produce considerable influence material performance.4. because discharging speed improves, and consumed power reduces, therefore saved electric energy greatly.5. because the resistance that is subjected to during this device work reduces, make consumed power reduce, so the noise of equipment generation also reduced, power transmission belt can prolong the life-span more than 5 times.6. close air-introduced machine, when starting main shaft,, can take remaining unwanted material in the pulverizing chamber out of from charging aperture because the moving air that main axis rotation produces can only be discharged from charging aperture; Close main shaft afterwards, when opening air-introduced machine again, both last remaining material in the pulverizing chamber can be exhausted, can reduce the temperature of complete machine again.
The speed that the suction that discharging opening is produced for the ease of adjustment wind sucting chamber passes screen cloth with the adjusting material, and then adjust material and in pulverizing chamber, process the time of pulverizing, the further improvement of technical solution of the present invention is: the sidewall that described wind sucting chamber exports is provided with air-vent and is located at adjustable air door on the air-vent.
For when not starting main shaft work, make full use of the air-introduced machine filter material at air-vent place, described air-vent is located at the upper side wall of wind sucting chamber's outlet.During use, can close main shaft, add material (mainly being Powdered or fine granularity) from the air-vent that is positioned at wind sucting chamber's outlet upper side wall to wind sucting chamber's outlet, when opening air-introduced machine, can utilize wind-force will more fine grain material from the exit sucking-off, and more coarse grained material is blocked in the outlet inboard, thereby plays a role in filtering (residue after filtering can be discharged after closing air-introduced machine).
The structure of above-mentioned adjustable air door can be as described below: comprise the air door that is buckled on the air-vent, the sidepiece of air door is hinged on the edge of air-vent through the jointed shaft perpendicular to air-vent.
When needs prolongation material is pulverized the time of processing in pulverizing chamber, rotating air door opens air-vent, then the part outside air enters in the wind sucting chamber from air-vent, air pressure in the wind sucting chamber is suitably increased, wind sucting chamber suitably reduces the suction that discharging opening produces, time of resting in the pulverizing chamber of material gets final product proper extension like this, thereby makes material pulverize more thoroughly.And by adjusting the openings of sizes of the relative air-vent of air door, can regulate from air-vent and enter air quantity in the wind sucting chamber, rest on time in the pulverizing chamber thereby regulate suction size that wind sucting chamber produces discharging opening and material.
In order further to improve discharging speed and discharging quantity, avoid partial material to be trapped in for a long time and cause material to process phenomenons such as inhomogeneous and overheated in the pulverizing chamber, the further improvement of technical solution of the present invention is: the two ends of described pulverizing chamber are equipped with discharging opening, be equipped with screen cloth on the discharging opening, charging aperture is located at the pulverizing chamber upper center.Above-mentioned wind sucting chamber guides a common outlet into by the discharging opening at pulverizing chamber two ends.
During work, finished material can be simultaneously from the outside sucking-off of the discharging opening at two ends in pulverizing chamber, avoids being positioned at pulverizing chamber in the past and is trapped in pulverizing chamber for a long time away from the partial material at discharging opening place and causes phenomenons such as material processing is inhomogeneous and overheated.
In order to ensure the granularity of the material that passes outwards through from screen cloth less and unlikely obstruction screen cloth mesh and guarantee the processing request that reaches certain, the further improvement of technical solution of the present invention is: described screen cloth is provided with towards a side of pulverizing chamber inner chamber can be with the retaining powder hammer leaf of main axis rotation.Because the obstruction effect of retaining powder hammer leaf, the more tiny particle that only meets processing request just can be crossed retaining powder hammer leaf and pass from screen cloth, and big long particle is kept off the powder hammer leaf and stops and continue to accept processing in pulverizing chamber.
In axial direction be provided with at least two rotating disks on the main shaft in the technique scheme perpendicular to axis, be connected with the equally distributed knife rest of the drum heart between adjacent two rotating disks, be hinged with the crushing knife tool that radially is provided with on the knife rest, the crushing knife tool on the different knife rests and the articulated position of knife rest stagger mutually.Being connected with equally distributed four knife rests of the drum heart between adjacent two rotating disks is preferred construction.Because three knife rests that will have now in the pulverizer change four knife rests into, thereby have increased the number of cutters that connects on the knife rest, and can shorten the length of cutter, reduce the resistance that is subjected to of cutter, thereby further reduce the power that consumes.
The inventor has dropped into above-mentioned pulverizer equipment in the bamboo wood powder processing actual production, the experiment proved that, pulverizer of the present invention is compared with general in the market pulverizer, the power savings of pulverizer of the present invention can reach more than 60%, the equipment working stability, easy care, remarkable in economical benefits can be saved equipment investment about about 50%.
