Description
Technical field
The present invention relates to a kind of fertilizer production device, particularly a kind of two-stage rotary screen with protective cover and dust exhaust apparatus.
Background technology
In composite heat transfer, before packed products, carry out sorting to fertiliser granulates to be absolutely necessary step, the uniformity of fertiliser granulates weighs the important indicator of fertilizer quality quality, because compound fertilizer granules has certain viscosity, leading portion screen cloth mesh is adopted to be greater than back segment screen cloth mesh in order to prevent screen cloth from blocking in prior art, particle larger for volume is preferentially sifted out, prevent blocking screen cloth from affecting the work of back segment screen cloth, but often the particle originally as qualified size is sifted out together, the particle to leading portion screen cloth sifts out is needed to re-start screening, reduce production efficiency, in addition because rotating speed when rotary screen works is higher, larger dust can be produced unavoidably, and most of dust is all containing chemical composition, if things go on like this works in such a case, powerful threat certainly will be created to the healthy of operating personnel.Therefore a kind of two-stage rotary screen with protective cover and dust exhaust apparatus is provided to have great importance.
Summary of the invention
The present invention is intended to solve the problem, and provides a kind of two-stage rotary screen with protective cover and dust exhaust apparatus.
For achieving the above object, the technical solution adopted in the present invention is as follows: a kind of two-stage rotary screen with protective cover and dust exhaust apparatus, comprise support, motor, shaft coupling, sieve axle, sieve nest, bracing frame, protective cover, dust exhaust apparatus, described motor is arranged on the bracket, described sieve axle two ends are connected with described support by bearing, described sieve nest is connected with described sieve axle by support frame as described above, described motor is connected with described sieve axle by shaft coupling, described sieve nest comprises the first screen cloth part and the second screen cloth part, described first screen cloth part mesh is less than the second screen cloth part mesh, the side of described protective cover is fixedly connected with support, opposite side and support removably connect, described dust exhaust apparatus and described waste material mouth are arranged in the same way.
Further, described second screen cloth part mesh size is equal to the size of fertilizer finished particle.
Further, the side of described protective cover is fixed together by welding manner and support, and opposite side is removably connected by bolt, nut and support.
Further, described dust exhaust apparatus specifically comprises dust shield, sweep-up pipe and CD-ROM drive motor, described dust shield is fixedly connected on described sieve nest and described discharging opening tip position in the same way, described dust shield is connected with described CD-ROM drive motor by described sweep-up pipe, described dust shield is flexibly connected with described sweep-up pipe, described CD-ROM drive motor also has a gauge tap, for controlling the duty of dust exhaust apparatus.
Further, described rotary screen also has a discharging opening, described discharging opening is arranged on described sieve nest bottom, described discharging opening comprises the first discharging opening and the second discharging opening, described first discharging opening coordinates with described first screen cloth part, described second discharging opening coordinates with described second screen cloth part, for fertiliser granulates different for granularity difference being come.
Further, described rotary screen also has a waste material mouth, and described waste material mouth is arranged on the contrary side of described motor.
Further, described sieve nest outer surface also comprises reinforcement, and described reinforcement also comprises the shaft orientation reinforcing rib arranged vertically and the radial reinforced rib prolonging radial arrangement.
Further, described reinforcement and described sieve nest form one by welding manner.
The invention provides the two-stage rotary screen with protective cover and dust exhaust apparatus; there is the screen cloth of two kinds of different mesh; prevent the generation blocking mesh situation; rotary screen top is provided with protective cover and dust exhaust apparatus in addition; the harmful substance produced when decreasing rotary screen work; operating personnel are played a very good protection, improves work quality and the efficiency of rotary screen.

In figure, 1-support, 2-first discharging opening, 3-second discharging opening, 4-motor, 5-shaft coupling, 6-sieve axle, 7-sieve nest, 7a-first screen cloth part, 7b-second screen cloth part, 8-reinforcement, 9-waste material mouth, 10-bracing frame, 11-charging aperture, 12-protective cover, 13-bolt, 14-nut, 15-dust exhaust apparatus, 16-dust shield, 17-sweep-up pipe, 18-gauge tap, 19-CD-ROM drive motor.
Specific embodiment
below in conjunction with accompanying drawing, invention is further described.
As Fig. 1, 2, shown in 3, before rotary screen work, first protective cover 12 is fastened, be fixed up with support 1 by bolt 13 and nut 14, restart dust exhaust apparatus 15, press gauge tap 18, CD-ROM drive motor 19 starts running, thus drive sweep-up pipe 17 action, then rotary screen is started, material enters in sieve nest 7 from charging aperture 11, motor 4 drives sieve axle 6 to move by shaft coupling 5, the rotation of sieve axle 6 drives bracing frame 10 to rotate, the rotation of bracing frame 10 drives sieve nest 7 to rotate, material enters in sieve nest 7 first through the first screen cloth part 7a, now particle waste material that is relatively little and that pulverized is screened out thus, discharged by the first discharging opening, fertilizer is subsequently through the second screen cloth part 7b, size due to the second screen cloth part 7b mesh equals the size of fertilizer finished particle, when fertilizer is through this screen cloth, for the fertilizer of finished particle size sifts out thus, discharged by the second discharging opening, the waste material being greater than finished particle is discharged by waste material mouth.Compare with traditional rotary screen; there is the screen cloth of two kinds of different mesh; prevent the generation blocking mesh situation; rotary screen top is provided with protective cover and dust exhaust apparatus in addition; the harmful substance produced when decreasing rotary screen work; operating personnel are played a very good protection, improves work quality and the efficiency of rotary screen.
Protection scope of the present invention do not limit to ten this, be anyly familiar with those skilled in the art in the technical scope that the present invention discloses, the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should define with claim is as the criterion.
