[0002] In the production of compound fertilizers, sorting fertilizer granules is an essential step before packaging the finished product. The uniformity of fertilizer granules is a measure of the quality of fertilizers. Because the compound fertilizer particles have a certain viscosity, in the prior art, in order to prevent the screen from clogging, the front screen mesh is larger than the rear screen mesh, and the larger particles are preferentially screened out to prevent the scr

Example Embodiment

[0016] The invention will be further described below in conjunction with the drawings.

[0017] Such as figure 1 , 2 As shown in Figure 3, before the trommel screen works, first buckle the protective cover 12 and fix it with the bracket 1 by bolts 13 and nuts 14, and then start the trommel screen. The material enters the screen body 7 from the feed port 11, and the motor 4 The screen shaft 6 is driven by the coupling 5 to move, the rotation of the screen shaft 6 drives the support frame 10 to rotate, and the rotation of the support frame 10 drives the screen body 7 to rotate. The material enters the screen body 7 and first passes through the first screen portion 7a. The relatively small particles and the pulverized waste materials are thus screened out and discharged from the first discharge port. The fertilizer then passes through the second screen part 7b, because the mesh size of the second screen part 7b is equal to the size of the finished fertilizer particles When the fe...

Abstract

The invention relates to a chemical fertilizer production apparatus, and specifically relates to a two-stage rotary screen with protection shield and firm support bracket; the two-stage rotary screen with protection shield and firm support bracket comprises a bracket, a motor, a shaft coupler, a screen shaft, a screen body, a support bracket, and a protection shield; the motor is arranged on the bracket; two ends of the screen shaft are connected with the bracket via bearings; the screen body is connected with the screen shaft via the support bracket; the motor is connected with the screen shaft via the shaft coupler; the screen body comprises a first screen mesh portion and a second screen mesh portion; the mesh holes of the first screen mesh portion are smaller than the mesh holes of the second screen mesh portion; one side of the protection shield is fixedly connected with the bracket; the other side is detachably connected with the bracket; the support bracket is arranged along the radial direction of the screen shaft in every 60 degrees; and the support frame is fixed connected with the screen shaft by means of welding. The provided two-stage rotary screen with protection shield and firm support bracket reinforces the firmness of the screen body, increases the work quality and efficiency of the rotary screen.

Description

technical field [0001] The invention relates to a fertilizer production equipment, in particular to a two-stage drum screen with a protective cover and a firm support frame. Background technique [0002] In the production of compound fertilizers, sorting fertilizer granules is an essential step before packaging finished products. The uniformity of fertilizer granules is an important indicator to measure the quality of fertilizers. Due to the certain viscosity of compound fertilizer granules, existing In the technology, in order to prevent the screen from clogging, the front screen mesh is larger than the rear screen mesh, and the larger particles are preferentially screened out to prevent the blockage of the screen from affecting the work of the rear screen. Particles are screened out together, and the particles screened out by the front screen need to be screened again, which reduces the production efficiency; in addition, due to the high speed of the drum sieve, it is in...
