Abstract
The invention relates to a chemical fertilizer production device, and in particular relates to a two-stage rotary screen with a firm support and a foldable roller. The two-stage rotary screen with the firm support and the foldable roller comprises a bracket, a motor, a coupling, a screen shaft, a screen body, supporting frames and the foldable rollers; the motor is arranged on the bracket; two ends of the screen shaft are connected with the bracket through a bearing; the screen body is connected with the screen shaft through the supporting frame; the motor is connected with the screen shaft through the coupling; the screen body comprises a first screen part and a second screen part; the meshes of the first screen part are smaller than those of the second screen part; the supporting frames are arranged every interval of 60 degrees along the screen shaft in the radial shaft and are fixedly connected with the screen shaft by welding; the foldable rollers are arranged at four corners of the bracket and are movably connected with the bracket. The two-stage rotary screen with the firming supporting frame and two types of screens has the advantages that the circumstance that the meshes are blocked can be prevented, the production cost can be saved, and the production efficiency can be greatly increased.
Description
Technical field
The present invention relates to a kind of fertilizer production device, particularly a kind of two-stage rotary screen with firmly support and folding rollers.
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 when rotary screen works, rotating speed is very fast, and the fertilizer of its inside heavier use a period of time sieve nest usually produces certain deformation, this additionally revises it with regard to needs, normal the carrying out produced of impact, reduce production efficiency, moreover most of cylinder quality is larger, usually need many people make a concerted effort or could be moved it by extra plant equipment when needing traveling roller to sieve, also have to adopt and shifting roller is set on drum sieve support corner location, but because rotating speed when rotary screen works is higher, the phenomenon that easy generation is rocked, affect work quality and the efficiency of rotary screen, reduce production efficiency.Therefore a kind of two-stage rotary screen with firmly support and folding rollers 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 firmly support and folding rollers.
For achieving the above object, the technical solution adopted in the present invention is as follows: a kind of two-stage rotary screen with firmly support and folding rollers, comprise support, motor, shaft coupling, sieve axle, sieve nest, bracing frame, folding rollers, 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, support frame as described above along described sieve Axial and radial according to 60 degree, each interval arrange and be fixedly connected with by welding manner with described sieve axle, described folding rollers is arranged on described support corner location and is flexibly connected with described support.
Further, described second screen cloth part mesh size is equal to the size of fertilizer finished particle.
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 Foldable structural member, and described folding rollers is connected with described support corner by described Foldable structural member.
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 firm bracing frame two kinds of screen clothes, there is the screen cloth of two kinds of different mesh, prevent the generation blocking mesh situation, rotary screen is provided with multiple bracing frame and folding rollers in addition, add the fastness of sieve nest, facilitate the movement of rotary screen, saved production cost, substantially increased production efficiency.
Accompanying drawing explanation

Fig. 2 is rotary screen left view schematic diagram of the present invention
Fig. 3 is drum screen body top view schematic diagram of the present invention
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-folding rollers, 13-Foldable structural member.
Specific embodiment
below in conjunction with accompanying drawing, invention is further described.
As Fig. 1, 2, shown in 3, 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 9, when needs traveling roller sieves, one jiao that first lifts support 1, Foldable structural member 13 is rotated to and support 1 four jiaos of same directions, again rotate folding rollers 12, make folding rollers 12 perpendicular to the ground, according to above-mentioned steps, same operation is carried out to the other triangle of support 1, after the corner folding rollers 11 of support 1 is all opened, rotary screen can be passed to desired position.Compare with traditional rotary screen, there is the screen cloth of two kinds of different mesh, prevent the generation blocking mesh situation, rotary screen is provided with multiple bracing frame and folding rollers in addition, adds the fastness of sieve nest, facilitate the movement of rotary screen, save production cost, substantially increase production efficiency.
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.
