Abstract
The invention relates to a chemical fertilizer production device, in particular to a drum screen with a protecting cover. The drum screen comprises a support, a motor, a coupler, a screen shaft, a screen body, supporting frames, a discharging port 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 discharging port is formed in the lower portion of the screen body, 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 with the protecting cover is simple in structure; compared with a traditional drum screen, the phenomenon that materials are thrown away along with rotation of the drum screen is prevented, and the working quality and efficiency of the drum screen are greatly improved.
Description
Technical field
The present invention relates to a kind of fertilizer production device, particularly a kind of rotary screen with protective cover.
Background technology
In composite heat transfer, before packed products, carry out sorting to fertiliser granulates to be absolutely necessary step, when the rotary screen of prior art works, major part is open environment, because rotating speed when rotary screen works is very fast, therefore often causes the material in sieve to throw away from screen cloth along with the rotation of sieve, needing when the material thrown away takes care of the pence, related personnel is additionally set this partial material is processed, add production cost, reduce production efficiency.Therefore a kind of rotary screen with protective cover 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.
For achieving the above object, the technical solution adopted in the present invention is as follows: a kind of rotary screen with protective cover, comprise support, motor, shaft coupling, sieve axle, sieve nest, bracing frame, discharging opening, 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 discharging opening is arranged on described sieve nest bottom, the side of described protective cover is fixedly connected with support, and opposite side and support removably connect.
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 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, structure is simple, compares with conventional rollers sieve, prevents the phenomenon that material is thrown out of with rotary screen rotation, substantially increases work quality and the efficiency of rotary screen.

In figure, 1-support, 2-discharging opening, 3-motor, 4-shaft coupling, 5-sieve axle, 6-sieve nest, 7-reinforcement, 8-waste material mouth, 9-bracing frame, 10-charging aperture, 11-protective cover, 12-bolt, 13-nut.
Specific embodiment
Below in conjunction with accompanying drawing, invention is further described.
As shown in Figure 1, 2, before rotary screen work, protective cover 11 is fastened, is fixed up with support 1 by bolt 12 and nut 13, starts rotary screen, material enters in sieve nest 6 from charging aperture 10, motor 3 drives sieve axle 5 to move by shaft coupling 4, and the rotation of sieve axle 5 drives bracing frame 9 to rotate, and the rotation of bracing frame 9 drives sieve nest 6 to rotate, qualified material is discharged through discharging opening 2, and waste material is discharged from waste material mouth 8.Compare with traditional rotary screen, prevent the phenomenon that material is thrown out of with rotary screen rotation, substantially increase 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.
