The invention relates to a chemical fertilizer production device, in particular to a drum screen with a protecting cover and two kinds of screen meshes. The drum screen comprises a support, a motor, a coupler, a screen shaft, a screen body, supporting frames and the protecting cover, wherein the motor is arranged on the support, the two ends of the screen shaft are connected with the support through bearings, the screen body is connected with the screen shaft through the supporting frames, the motor is connected with the screen shaft through the coupler, the screen body comprises a first screen mesh part and a second screen mesh part with the mesh openings larger than the mesh openings of the first screen mesh part, one side of the protecting cover is fixedly connected with the support, and the other side of the protecting cover is detachably connected with the support. The drum screen is provided with the two kinds of screen meshes with the mesh openings, so that the situation that the mesh openings are blocked is prevented; the upper portion of the drum screen is provided with the protecting cover, so that it is prevented that many fertilizer particles are thrown out when the drum screen works, and the work quality and efficiency of the drum screen are improved.
Description
Technical field
The present invention relates to a kind of fertilizer production device, particularly a kind of rotary screen with protective cover two kinds of screen clothes.
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, when the rotary screen of prior art works in addition, major part is open environment, because when rotary screen works, rotating speed is very fast, therefore the material in sieve is often caused to throw away from screen cloth along with the rotation of sieve, need additionally to arrange related personnel to process this partial material when the material thrown away takes care of the pence, add production cost, reduce production efficiency, therefore in order to reduce production cost, enhance productivity, a kind of rotary screen with protective cover two kinds of screen clothes is provided to have great importance.
Summary of the invention
The present invention is intended to solve the problem, and provides a kind of rotary screen with protective cover two kinds of screen clothes.
For achieving the above object, the technical solution adopted in the present invention is as follows: a kind of rotary screen with protective cover two kinds of screen clothes, comprise support, motor, shaft coupling, sieve axle, sieve nest, bracing frame, protective cover, 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.
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 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 rotary screen with protective cover two kinds of screen clothes, have the screen cloth of two kinds of different mesh, prevent the generation blocking mesh situation, rotary screen top is provided with protective cover in addition, throw away a large amount of fertiliser granulates when preventing rotary screen from working, improve work quality and the efficiency of rotary screen.

Specific embodiment
?below in conjunction with accompanying drawing, invention is further described.
As Fig. 1, 2, shown in 3, before rotary screen work, protective cover 12 is fastened, be fixed up with support 1 by bolt 13 and nut 14, start rotary screen, 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, have the screen cloth of two kinds of different mesh, prevent the generation blocking mesh situation, rotary screen top is provided with protective cover in addition, throws away a large amount of fertiliser granulates when preventing rotary screen from working, and 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.
