Below in conjunction with specific embodiment and accompanying drawing the utility model is described further; Set forth more details in the following description so that make much of the utility model; But the utility model obviously can be implemented with the multiple alternate manner that is different from this description; Therefore those skilled in the art can do similar popularization, deduction according to practical situations under the situation of the utility model intension, should be with the protection domain of content constraints the utility model of this specific embodiment.
Fig. 1 is the internal structure sketch map of the beater disintegrating machine of an embodiment of the utility model.It should be noted that these and follow-up other accompanying drawing all only as an example, it is not to be to draw according to the condition of equal proportion, and should not limit as the protection domain formation to the actual requirement of the utility model with this.
As shown in Figure 1, this beater disintegrating machine can comprise base A and the door B that is provided with on it, and door B top offers charging aperture J, and charging aperture J place can have the turnover panel N of downward-sloping extension.Be provided with in the door B and press screen frame C and sieve sheet D, press screen frame C and sieve sheet D to constitute a major arc shape on the whole, for example just round major arc is oval major arc also, and the opening of this major arc up.Press screen frame C to be provided with rotor E with sieving in the sheet D, the excircle of rotor E is provided with a plurality of hammer leaf F.Each rotor E is provided with 4 hammer leaves among Fig. 1, but it is individual to be provided with other number.In addition, the number of rotor E can be one incessantly also.Fig. 2 is the internal structure sketch map of the beater disintegrating machine of another embodiment of the utility model.As shown in Figure 2, the number of rotor E wherein is 2, certainly can also be for more a plurality of.
Please refer to illustrated in figures 1 and 2ly, rotor E constitutes pulverizing chamber with pressing screen frame C and sieve sheet D.If the number of rotor E is more than 1, then each rotor E and the pressure screen frame C around himself constitute pulverizing chamber respectively with sieve sheet D.The above-mentioned a plurality of pulverizing chamber that constitute respectively can be connected each other, and are as shown in Figure 2.Directly over charging aperture J bottom, rotor E, be provided with air delivery pipe I, the number of air delivery pipe I is corresponding with the number of rotor E, and both occur in pairs.Have the gas outlet on the air delivery pipe I, in pulverizing chamber, carry high pressure air, the concrete structure of air delivery pipe I details in the back.
Fig. 3 is the external structure sketch map of air delivery pipe of the beater disintegrating machine of an embodiment of the utility model.As shown in Figure 3, air delivery pipe I one end is air inlet L, an end plug for seal.Blow to the hollow bronchus M of a side of pulverizing chamber along a plurality of two ends connection of radially can being distributed with of air delivery pipe I; This bronchus M one end connects the main part of air delivery pipe I; The other end is towards pulverizing chamber, so the outlet of this bronchus M is the gas outlet O of air delivery pipe I.
Fig. 4 is the external structure sketch map of air delivery pipe of the beater disintegrating machine of another embodiment of the utility model.As shown in Figure 4, air delivery pipe I blows to the gas outlet O ' that radially can have a vertical masonry joint shape of a side of pulverizing chamber along air delivery pipe I.
Fig. 5 is the cross section structure sketch map of air delivery pipe of the beater disintegrating machine of an embodiment of the utility model.In this preferred embodiment, on the basis of the air delivery pipe I shown in Fig. 3, it also can have baffle H (not shown among Fig. 3) in the left and right sides of a plurality of bronchus M.This baffle H has protected the bump of avoiding comminuting matter along a plurality of bronchus M of air delivery pipe I.
Fig. 6 is the cross section structure sketch map of air delivery pipe of the beater disintegrating machine of another embodiment of the utility model.Similarly, on air delivery pipe I, the left and right sides of the gas outlet O ' of vertical masonry joint shape has baffle H '.O ' extends two baffle H ' from the gas outlet among the figure, and the air throughput direction that makes air delivery pipe I has protected gas outlet O ' not damaged by the bump of comminuting matter again simultaneously towards pulverizing chamber.
No matter for which kind of the air delivery pipe I shown in Fig. 3 to Fig. 6, the gas outlet that its air inlet L fails wind apparatus (not shown) through electromagnetic impulse valve/high pressure nozzle (not shown) and is connected.Should fail wind apparatus and electromagnetic impulse valve/high pressure nozzle acting in conjunction, produce and carried high pressure air continuation or discontinuity to air delivery pipe I.
The pulverizer of the utility model can be through increasing or the interior current rate of adjusting pulverizing chamber; Can be continuously or delivery air in pulverizing chamber discontinuously; Destroy the logistics ring that material forms in the pulverizing chamber and dispel the sticky material of blocking screen cloth; Qualified material is pulverized away as early as possible, shortened the pulverizing time, improved crush efficiency.
The one routine method for using of the utility model is following: will be contained in the air inlet of the air delivery pipe on the pulverizer and the gas outlet of electromagnetic impulse valve earlier and be connected; Again electromagnetic impulse valve is connected with defeated air port on the defeated wind apparatus such as extraneous air pump, blower fan; And the impact that configures the external electromagnetic pulse as required at interval duration and the operating pressure that regulates electromagnetic impulse valve, configure current rate and air pressure.When pulverizer is worked; The electromagnetic impulse valve short time many times discharges high pressure air and sprays in pulverizing chamber through the air delivery pipe gas outlet; Can be continuously or in pulverizing chamber, carry high pressure draught discontinuously; So high pressure draught has produced strong wallop in pulverizing chamber, the material in the pulverizing chamber is thoroughly hit unrest, destroyed the formation of the material ring of comminuting matter.High pressure draught also breaks up sticky material on the sieve sheet, and the mediation screen cloth has been eliminated stifled sieve phenomenon, thereby made material promptly be crushed to the granularity of setting, and in the shortest time, pulverized out pulverizing chamber more easily, has shortened the pulverizing time, has improved crush efficiency.
The utility model is through rationally being provided with the position of air delivery pipe; The high pressure draught of in pulverizing chamber, carrying; When high pressure draught passes the space between hammer leaf and hammer leaf and hammer leaf cage ring and the hammer leaf cage ring; And under the rotary action of rotor; The random high pressure draught spray that forms will be loose in whole pulverizing chamber, makes the impacting with high pressure air-flow impact the comminuting matter to the whole pulverizing chamber fully, thereby has effectively overcome the thing circulation phenomenon that in pulverizing chamber, is produced when material is pulverized; And the stifled sieve that causes by the comminuting matter of high grease, multifilament, glutinous viscosity, water content height or dampness with stick with paste the sieve low problem of pulverizer crush efficiency that phenomenon caused, thereby improved crush efficiency, increased output, saved energy consumption.
In addition, the pulverizer of the utility model respectively is provided with baffle in the both sides of air inlet pipe, can protect air inlet pipe directly not contact comminuting matter with nozzle, and the defective that efficiently solves on the prior art is not enough.
Though the utility model with preferred embodiment openly as above, it is not to be used for limiting the utility model, and any those skilled in the art can make possible change and modification in spirit that does not break away from the utility model and scope.Therefore, every content that does not break away from the utility model technical scheme, all falls within the protection domain that the utility model claim defined any modification, equivalent variations and modification that above embodiment did according to the technical spirit of the utility model.
