Detailed description of the invention
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, therefore the utility model is not by the restriction of following public specific embodiment.
Embodiment one:
Fig. 1 is the structural representation that the utility model has the embodiment one of the pulverizer of central shaft air inlet system.Fig. 2 is the sectional view that Fig. 1 cuts open along A-A line.It should be noted that these and follow-up other accompanying drawing all only exemplarily, it is not draw according to the condition of equal proportion, and should not be construed as limiting in this, as to the protection domain of the utility model actual requirement.
As depicted in figs. 1 and 2, disclose a kind of pulverizer with central shaft air inlet system in an embodiment of the present utility model, it comprises upper machine body 10 fixing up and down and lower body 20.Offer at least one charging aperture 11 on the top of upper machine body 10, in the pulverizing chamber of upper machine body 10, be provided with at least one rotor 30 and sieve 12, sieve 12 surrounding rotor 30 is arranged, and is communicated with charging aperture 11.The central shaft of rotor 30 offers an air admission hole 13, and on rotor 30, is provided with some ventholes 14 being communicated to air admission hole 13, by venthole 14 to delivery air in described pulverizing chamber.
Preferably, by venthole 14 around the periphery being distributed in described central shaft.The quantity of venthole 14 can be chosen as two, four or six, is arranged in the outer surface of described central shaft radially.
In addition, need in the periphery of rotor 30 to be fixed with some hammer leaves 15, for comminuting matter.At charging aperture 11, place is provided with turnover panel 16, and one end of turnover panel 16 is rotatably mounted to the centerline of charging aperture 11, and is positioned at directly over corresponding hammer leaf 15, and the oblique side inwall against charging aperture 11 of the other end of turnover panel 16.
Air intake equipment (not shown) can be connected with at air admission hole 13 place of described central shaft, can continuation or discontinuity conveying air and compressed air and high pressure air, also can not tap into wind devices and air draught voluntarily with sample central shaft fresh air inlet place.Described air intake equipment can select high pressure air rifle or electromagnetic impulse valve.The shape of sieve 12 is preferably circular arc, and circular arc here can be positive round arc or elliptic arc.
Such as, electromagnetic impulse valve is connected to conveying high-pressure compressed air in pulverizing chamber.When pulverizer works, operation range duration and the operating time of electromagnetic impulse valve is set by relevant device, high compression air is inputted in pulverizing chamber, under the rotation of rotor, so venthole within a short period of time of this central shaft air inlet system is to inject high pressure gas in whole pulverizing chamber, comminuting matter is hit unrest by impacting with high pressure air-flow instantaneously that produce in pulverizing chamber, and the material ring destroying material is formed.Sticky material in sieve breaks up by high pressure draught on the other hand, dredge sieve aperture, eliminated stifled sieve phenomenon, and the granule crushed material of logistics ring internal layer is blowed to compass screen surface side, thus improve the crush efficiency of pulverizer, add production capacity, save energy consumption.
Embodiment two:
Fig. 3 is the structural representation that the utility model has the embodiment two of the pulverizer of central shaft air inlet system.
As shown in Figure 3, the structure of the present embodiment is substantially identical with embodiment one, and its difference is: upper body machine 10 is provided with two charging apertures 11, the corresponding pulverizing chamber of each charging aperture 11, a rotor 30 is respectively set in described pulverizing chamber, thus forms dual-rotor crushing machine.
Describe according to said structure, when the pulverizer using the utility model to have central shaft air inlet system carries out comminuting matter, rotor 30 High Rotation Speed, and the air pressure at rotor 30 place is less than the air pressure of rotor 30 periphery.The extraneous air at pulverizer place is given vent to anger after the air admission hole 13 entering central shaft by venthole 14, and to the pulverizing chamber conveying air of pulverizer.Air-flow in the rotation of rotor 30 in 360 ° to delivery air in whole disintegrating chamber of crushing machine, the air-flow blowed in pulverizing chamber will blow the material after disorderly pulverizing, thus destroys logistics ring.Also the short grained material of logistics ring internal layer is blowed to outside on the other hand, the material blocking sieve 12 also dispels by this air-flow simultaneously, has dredged sieve aperture, thus makes material promptly be pulverized out pulverizing chamber, saves energy consumption, improves crush efficiency.
Equally, the air-flow of described central shaft air inlet system also reduces the high temperature that the central shaft of rotor and bearing produce under long-term High Rotation Speed, thus extends the service life of central shaft and bearing.And in pulverizer, room is sieved with stifled because of there being this air inlet system to destroy logistics ring, and the temperature reducing material during comminuting matter raises phenomenon, thus pulverizes the hidden danger of catching fire of some material generation when avoiding pulverizer work on certain level.
In sum, the pulverizer that the utility model has central shaft air inlet system arranges air inlet system at central shaft, can be dispelled by the material blocking sieve by air-flow, dredge sieve aperture, thus make material promptly be pulverized out pulverizing chamber, can energy consumption be saved like this, improve crush efficiency.
Although the foregoing describe detailed description of the invention of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
