Top is connected, and lower bin is connected with the lower section of sieving plate in main cabin, and deflector is arranged in secondary cabin, under crushing shell
Side, deflector is obliquely installed to main cabin.
Further, the pneumatic breaker includes cylinder and dental lamina, and dental lamina is located at setting in parallel above crushing shell,
Cylinder and dental lamina are connected with shaft coupling, and wherein shaft coupling and cylinder are threaded connection, and shaft coupling and dental lamina are pin connection.
Further, the cylinder is provided with travel switch.
Further, the dental lamina is made of high hardness material.
Further, the sieving plate and crushing shell are processed using 12Mn plates.
The utility model includes main cabin, secondary cabin, sieving plate, crushing shell and deflector, when ash and slagging are from charging aperture
Into after main cabin, fine ash and slagging will be sized plate separation, and fine ash enters the pump that puts in storage by sieving plate from discharging opening, and slagging is then
Into secondary cabin, fall on crushing shell, broken through pneumatic breaker, the slagging after crushing is fallen on through the gap on crushing shell to be led
Flow on plate, the pump that puts in storage is entered from discharging opening, participate in conveying, this equipment safety is reliable, simple to operate, and operation is convenient, solves slagging
The problems such as grey block can not convey the plugging of generation.
Pneumatic breaking sifter is used to handle the lime-ash containing larger influence induction system operation in conveying material
Grain.The equipment normal work and should be able to ensure the stabilization of its mechanical structure and durable under severe operating mode.Its principle is to utilize
The grain sorting that baffle plate in sifter will be greater than certain diameter comes out, and delivers in crushing mechanism, broken using physical impact
Mode the lime-ash of bulky grain is broken into the little particle lime-ash that disclosure satisfy that conveying is required, then delivery system is entered by cylinder manifold
In system.
【Brief description of the drawings】
Fig. 1 is structural representation of the present utility model;
In figure:Main cabin 1, secondary cabin 2, charging aperture 3, discharging opening 4, sieving plate 5, crushing shell 6, dental lamina 7, deflector 8, connection
Axle device 9, cylinder 10.
【Embodiment】
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, pneumatic breaking sifter is made up of main cabin 1 and secondary cabin 2, main cabin 1 and secondary cabin 2 are independent
Work, is arranged side by side, is independent of each other, and main cabin 1 allows the fine ash less than screen cloth grid directly to pass through, and secondary 2 pairs of cabin is more than sieve
The grey solid impurity particle of net grid is crushed.The main upper end of cabin 1 is that charging aperture 3, lower end are discharging openings 4, and sieving plate 5 is inclined at
Between charging aperture 3 and discharging opening 4, the screen cloth grid that sieving plate 5 is provided with can be sieved to lime-ash, and sieving plate 5 simultaneously will be big
