Accompanying drawing explanation
The accompanying drawing that forms the application's a part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is according to the structural representation of sand system processed of the present utility model;
Fig. 2 is the drive connection schematic diagram according to grading adjuster of the present utility model; And
Fig. 3 is the control schematic diagram according to grading adjuster of the present utility model.
The specific embodiment
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As shown in Figure 1, according to grading adjuster of the present utility model, comprise grating machine body 10 and feed arrangement, feed arrangement comprises charging triple valve 20, and charging triple valve 20 comprises feeding mouth 21, the first discharging opening 22 and the second discharging opening 23; The first discharging opening 22 is connected with the charging aperture of grating machine body 10, and the second discharging opening 23 is connected in the bypass drainage line 24 of grating machine body 10 with bypass.Grading adjuster of the present utility model is by arranging triple valve, in the grading adjuster course of work, when rotating speed reduces extremely when putty (putty or will), by triple valve, the first discharging opening 22 is closed, and the second discharging opening 23 is opened, thereby make building stones directly enter next step operation processing by bypass drainage line 24, thereby prevent from causing whole sand system processed to stop because of grading adjuster putty, only need to stop separately grading adjuster and clear up putty.
Preferably, shown in Fig. 1 and Fig. 3, grading adjuster also comprises control device 30, and control device 30 controls charging triple valve 20 and cuts out the first discharging opening 22 and open the second discharging opening 23 in the time that the roller rotating speed of grating machine body 10 reduces, and stops grating machine body 10.Notice arranges control device 30, in the time that rotating speed reduces extremely, automatically close charging and the grating machine body 10 of grating machine body 10, and make building stones directly enter next treatment process from the second discharging opening 23 through bypass drainage line 24, can avoid on the one hand whole system to shut down, thereby improve sand efficiency processed; On the other hand, can stop in time grating machine body 10, and close its charging, the putty degree of grating machine body 10 is reduced, can alleviate to a certain extent workload and the difficulty of cleaning putty; In addition, also can play protection to grading adjuster, prevent long-time putty and cause grading adjuster belt to burn.
More preferably, shown in Fig. 2 and Fig. 3, grading adjuster also comprises checkout gear, and checkout gear passes through to detect motor speed and the roller rotating speed of grating machine body 10, thereby judges whether the rotating speed of the roller of grating machine body 10 reduces extremely.Particularly, grating machine body 10 comprises roller and motor, on motor, be provided with driving pulley 11, driven pulley 12 is set on roller, driving pulley 11 is by belt drives driven pulley 12, checkout gear comprises the first checkout gear of the rotation speed n 1 that detects driving pulley 11 and detects the second detection device of the rotation speed n 2 of driven pulley 12, detect respectively rotation speed n 1 and the n2 of driving pulley 11 and driven pulley 12 by two speed probes, the in the situation that of normal production, because driving pulley 11 and driven pulley 12 pass through belt transmission, the two linear velocity should be substantially equal, be that n1/n2 equates substantially with R2/R1, in certain scope, maintain dynamic equilibrium, wherein R1 is the radius of driving pulley 11, and R2 is the radius of driven pulley 12.
But, once grading adjuster generation putty or will putty, the inevitable sharply reduction of rotation speed n 2 of roller, even stop, make n1/n2 be greater than R2/R1 and exceed certain scope, by preset value is set, can be by judging n1/n2-R2R1 judges while whether being greater than preset value that grating machine body 10 whether will putty or putty, thereby make charging triple valve 20 close the first discharging opening 22 and open the second discharging opening 23, and stop grading adjuster, avoid stopping whole sand system processed, and can prevent that belt from burning because skidding.After cleaning grading adjuster, i.e. changeable time normal operating conditions.
In addition, because building stones are normal operating conditions from feeding mouth 21 to first discharging openings 22 of charging triple valve 20, be also groundwork state, in order to reduce the resistance of building stones, make building stones operation more unobstructed, the feeding mouth 21 of charging triple valve 20 and the first discharging opening 22 are on same straight line.
The utility model also provides a kind of sand system processed, comprise elevator 40 and aforesaid grading adjuster, the discharging opening of grating machine body 10 is all connected with the charging aperture of elevator 40 with bypass drainage line 24, also while normally production, building stones enter grating machine body 10 from the first discharging opening 22, then enter elevator 40, complete production procedure, now n1/n2 equates substantially with R2/R1, in certain interval, maintains balance.In the time detecting that n1/n2 is greater than R2/R1 and exceedes preset value, as shown in Figure 2, control device 30 is controlled charging triple valve 20, make building stones directly enter elevator 40 from the second discharging opening 23, stop grating machine body 10 moves simultaneously, avoid belt to burn because skidding, after cleaning level grating machine body 10, i.e. changeable time normal operating conditions.
As can be seen from the above description, the utility model the above embodiments have realized following technique effect:
According to grading adjuster of the present utility model and sand system processed, by triple valve is set, in the grading adjuster course of work, when rotating speed reduces extremely, by triple valve, the first discharging opening 22 is closed, and the second discharging opening 23 is opened, thereby make building stones directly enter next step operation processing by bypass drainage line 24, thereby prevent from causing whole sand system processed to stop because of grading adjuster putty, only need to stop separately grading adjuster and clear up putty.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
