Description

Technical Field

[0001] The utility model belongs to the technical field of chemical fertilizer production equipment, and particularly relates to a particle separation roller for compound fertilizer granulation. Background Art

[0002] In the process of producing compound fertilizer, a granulation device is needed for granulation, that is, the powdery compound fertilizer is made into granular compound fertilizer through the granulation device, which is convenient for transportation and use.

[0003] Currently, the granulation process of the granulation device is usually as follows: a pair of extrusion rollers are used to extrude the powdery compound fertilizer into particles distributed in two dimensions, and the edges of the particles are connected to each other; then, they are dispersed and separated by a pair of separation rollers to complete the granulation operation.

[0004] Since compound fertilizer is corrosive, in order to prevent the separation roller from being corroded by the compound fertilizer and causing rust on the surface, the surface of the separation roller usually has a corrosion-resistant layer. However, during the operation of the separation roller, the fertilizer constantly collides and rubs against the separation roller, which will cause the corrosion-resistant layer on the surface of the separation roller to wear. The positions where the corrosion-resistant layer is worn and missing will still be corroded and rusted.

[0005] Moreover, the corrosion-resistant layer on the crushing teeth of the separation roller is more likely to wear compared to the roller body; therefore, usually, the crushing teeth on the separation roller are corroded and rusted before the roller body. However, after the crushing teeth rust, the entire separation roller needs to be replaced, resulting in low service life, waste of resources, and increased production costs.

[0030] Please refer to Figures 1 to 2 , and now the particle separation roller for compound fertilizer granulation provided by the present utility model will be described. The particle separation roller for compound fertilizer granulation includes a roller body, a plurality of connecting columns 21 and a plurality of crushing teeth 30; the plurality of connecting columns 21 are arranged at intervals along the circumferential and axial directions of the roller body. One end of the connecting column 21 is connected to the roller body, and the other end protrudes from the roller body; the plurality of crushing teeth 30 correspond to the connecting columns 21 one by one, and the crushing teeth 30 are detachably connected to the connecting columns 21.

[0031] The beneficial effect of the particle separation roller for compound fertilizer granulation provided by the present utility model is that: compared with the prior art, for the particle separation roller for compound fertilizer granulation provided by the present utility model, the crushing teeth 30 are connected to the roller body through the connecting columns 21, and the crushing teeth 30 are detachably connected to the connecting columns 21.

[0032] As Figure 1 and Figure 2 shown, in a specific implementation manner of the particle separation roller for compound fertilizer granulation provided by the embodiment of the present utility model, the crushing teeth 30 are in a columnar structure, effectively ensuring the crushing effect and structural strength of the crushing teeth 30.

[0033] As Figure 1 and Figure 2 shown, in a specific implementation manner of the particle separation roller for compound fertilizer granulation provided by the embodiment of the present utility model, one end of the connecting column 21 protruding from the roller body is provided with a thread, and a threaded hole is opened at the bottom of the connecting column 21 for threaded cooperation with the connecting column 21 to facilitate the disassembly and replacement of the crushing teeth 30.

[0034] As Figure 1 and Figure 2 shown, in a specific implementation manner of the particle separation roller for compound fertilizer granulation provided by the embodiment of the present utility model, a plurality of receiving grooves are opened on the roller body, and the receiving grooves correspond to the crushing teeth 30 one by one. One end of the crushing teeth 30 is placed in the receiving groove so that the crushing teeth 30 can completely wrap the connecting column 21, avoiding corrosion of the connecting column 21 and also avoiding material jamming between the gaps of the crushing teeth 30 and the roller body.

[0035] Specifically, the crushing teeth 30 are in sealing fit or clearance fit with the receiving groove.

[0036] As Figure 1 and Figure 2 shown, in a specific implementation manner of the particle separation roller for compound fertilizer granulation provided by the embodiment of the present utility model, it further includes a plurality of sealing gaskets 40. The sealing gaskets 40 correspond to the receiving grooves one by one. The sealing gaskets 40 are clamped between the receiving grooves and the crushing teeth 30, and are in sealing fit with the roller body and the crushing teeth 30, improving the sealing performance between the crushing teeth 30 and the receiving groove and further avoiding corrosion of the connecting column 21.

[0037] As Figure 1 and Figure 2 shown, in a specific implementation manner of the particle separation roller for compound fertilizer granulation provided by the embodiment of the present utility model, the roller body includes a roller shaft 11 and a roller sleeve. The roller sleeve is sleeved on the roller shaft 11 and is connected to the roller shaft 11 to rotate synchronously with the roller shaft 11; a plurality of through holes are opened on the roller sleeve, and the through holes correspond to the connecting columns 21 one by one. One end of the through hole facing the roller sleeve is provided with a clamping groove, and one end of the connecting column 21 is provided with a clamping block 22. The connecting column 21 is adapted to penetrate into the through hole, and the clamping block 22 on the connecting column 21 is adapted to be clamped into the clamping groove.

[0039] Further, a magnet is provided on the clamping block 22 or the clamping block 22 is magnetized so that the clamping block 22 has magnetism and can be adsorbed on the roller sleeve, avoiding the connecting column 21 sliding out of the through hole by itself when the connecting column 21 is installed, which is convenient for installation.

[0040] Further, as Figure 1 and Figure 2 shown, in a specific implementation manner of the particle separation roller for compound fertilizer granulation provided by the embodiment of the present invention, the roller sleeve includes two half sleeves 12 and a plurality of fastening bolts 13. The two half sleeves 12 are buckled together, and the fastening bolts 13 pass through the half sleeves 12 and are connected to the roller shaft 11.

[0041] It should be noted that after the roller body is used for a period of time, it will inevitably be corroded and rusted. At this time, the roller body needs to be replaced. The roller body is set to be composed of a split roller shaft 11 and a roller sleeve. When replacing, only the roller sleeve needs to be replaced; and the roller sleeve is composed of two half sleeves 12 and is fixed to the roller shaft 11 through the fastening bolts 13. When replacing the roller sleeve, only the fastening bolts 13 need to be unscrewed, and the half sleeve 12 can be directly removed without disassembling the separation roller from the granulation equipment, which is more convenient and fast to replace the roller sleeve.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
