The specific embodiment
The purpose of this invention is to provide a kind of pulverizer, be used for pulverizing efficiently waste printed circuit boards etc., with convenient follow-up recovery and utilization.
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 to Fig. 3, Fig. 1 is the described pulverizer front view of the embodiment of the invention; Fig. 2 is the described pulverizer left view of the embodiment of the invention; Fig. 3 is the described pulverizer vertical view of the embodiment of the invention.
The described pulverizer 1 of the embodiment of the invention, comprise feed hopper 11, the pulverizing cavity 12 that is connected with feed hopper 11, described pulverizing cavity 12 and plant bottom case 13 fixed installations, in described pulverizing cavity 12, main shaft 14 is installed, the rotating blade 15 with described main shaft 14 interlocks is installed on the described main shaft 14.
Pulverize cavity 12 by constituting with the hard-wired liner plate 12a of plant bottom case, screen cloth 17 and end plate 12b.
Described pulverizing cavity 12 (also claiming the machine chamber) can be made up of upper and lower two semicircular cylinders, becomes cylindrical structure after the closure.On upper and lower two semicircular cylinder inside circumference directions of machine chamber wall, 2 rows or most rows' such as 3 rows or 4 rows the sub-liner plate of arc can be installed specifically.(do not adorn the liner plate except that the machine chamber, the right of charging aperture and screen cloth, sub-liner plate all be housed).
Sub-liner plate can be connected and fixed by bolt and machine chamber wall, and sub-liner plate inner arc is worn tooth-shape structure, the liner plate 12a that sub-liner plate joins and formed the stationary knife effect.
Specifically can offer counter sink on the sub-liner plate, be connected and fixed by dormant bolt and machine chamber wall.
Described liner plate 12a has a plurality of toothed projections, can be parallel to each other between the described toothed projections.Described toothed projections and main shaft 14 are parallel to each other.
Described main shaft 14 can drive by the belt pulley 22 of motor 21 and realize rotating.
In order to make described pulverizer 1 more compact structure of the embodiment of the invention, device integration is provided, the axle and the described main shaft 14 of described belt pulley 22 can be coaxial configuration.Motor 21 can be arranged on sustained height with described main shaft 14.
Described pulverizer 1 also comprises the cavity 16 that is connected with described pulverizing cavity 12, and screen cloth 17 is arranged between described cavity 16 and the described pulverizing cavity 12.
Described cavity 16 is by pipeline 18 and take out material blower fan 19 UNICOMs, and described pipeline 18 is connected with discharging opening 20.
Described pulverizing cavity 12 can be divided into upper and lower two parts, and top 121 and described feed hopper 11 can adopt the installation that interfixes of mechanical connection manner such as welding grade.Lower part 122 and plant bottom case 13 also can adopt the installation that interfixes of mechanical connection manner such as welding grade.
Can install by hinges 24 between top 121, lower part 122 two parts.
Between top 121, lower part 122 two parts, specifically can realize installing by two or more hinges 24 that are arranged on top 121,122 the same sides, lower part.
Open conveniently in order to overhaul etc., described top 121 or described feed hopper 11 link to each other with hydraulic pressure cap-opening mechanism 25, and described top 121 and feed hopper 11 can be realized opening and closing of described top 121 and lower part 122 under 25 effects of hydraulic pressure cap-opening mechanism.
In order to guarantee opening and closing of hydraulic pressure cap-opening mechanism described top 121 of 25 smooth realizations and lower part 122, between described top 121 or described feed hopper 11 and the hydraulic pressure cap-opening mechanism 25, can realize mutual installation by hinge or bearing pin.
Because the rotating blade 15 with described main shaft 14 interlocks is installed on the main shaft 14 of the described pulverizer 1 of the embodiment of the invention, when the pulverized material of needs (for example waste and old circuit board) enters into pulverizing cavity 12, the rotating blade 15 that can be driven by main shaft 14 and pulverize shear action cutting between cavity 12 (liner plate), because rotating blade 15 rotation at a high speed of described main shaft 14 interlocks, material constantly collides with pulverizing cavity 12 (part that is parallel to described main shaft 14 interlocks) under centrifugal action, forms granular material.Material particles after pulverizing can discharge from discharging opening under the draft of taking out the material blower fan during less than the aperture of screen cloth 17 by the road.Therefore, the described pulverizer 1 of the embodiment of the invention can be realized pulverized material grinding effectively.
Material particles after the described pulverizer of the embodiment of the invention 1 is pulverized (or claiming powder) is further processed as need, can be directly and discharging opening 20 UNICOMs carry out subsequent operation, therefore, the described pulverizer 1 of the embodiment of the invention makes things convenient for follow-up recovery and utilization.
The described pulverizer 1 of the embodiment of the invention, described screen cloth 17 can vertically mutually be provided with described main shaft 14.Be that described screen cloth 17 is parallel to each other with rotating blade 15, avoided positive friction between screen cloth 17 and the rotating blade 15.
For dust stratification or solid accumulation on the screen cloth 17 that prevents the described pulverizer of the embodiment of the invention, described cavity 16 is provided with pulse valve 23 near the sidewall of described screen cloth 17 positions.
Because the material particles after the described pulverizer of the embodiment of the invention is pulverized is during greater than the aperture of screen cloth 17, the material particles of this moment still in pulverizing cavity 12, material particles under centrifugal action constantly with pulverize cavity (liner plate) collision, pulverize.Material particles after pulverizing can be under the effect that take out material blower fan 19 less than with the aperture of the orthogonal screen cloth 17 of main shaft the time, and 18 from discharging opening 20 dischargings by the road.But because long-time running, screen cloth 17 may dust stratification or solid accumulation, influences the material particulate emission.Described cavity 16 is provided with pulse valve 23 near the sidewall of described screen cloth 17 positions, can set predetermined time interval as required, and at interval regular to schedule blowback compressed air is to screen cloth 17, thus the solid accumulation on the removal screen cloth 17.Therefore, the described pulverizer 1 of the embodiment of the invention can be realized effectively by the pulverizing of comminuting matter and collection.
The pulverizing cavity 12 of the described pulverizer of the embodiment of the invention also can be divided into upper and lower two parts, and top 121 and described feed hopper 11 can adopt the installation that interfixes of mechanical connection manner such as welding grade.Lower part 122 and plant bottom case 13 also can adopt the installation that interfixes of mechanical connection manner such as welding grade.Can install by hinges 24 between top 121, lower part 122 two parts.
Referring to Fig. 4, this figure is the described mesh structure figure of the embodiment of the invention.
When pulverizing cavity 12 was divided into top 121, lower part 122 two parts, described screen cloth 17 also will be divided into upper screen cloth 171 and lower screen cloth 172 two parts, to realize the function of screen cloth 17.
More than to described pulverizer that the embodiment of the invention provided, be described in detail, used specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
