Abstract
Description
[0001] The proposed invention is intended for granulating bulk components in the chemical and other industries.
[0002] A granulator for bulk components is known, comprising a housing, a rotating shaft mounted inside it with mixing elements forming a gap with the housing, a moistening device, and a loading and unloading device. The housing is designed as a hollow truncated cone, the larger base of which is located on the side of the unloading device, and the length and thickness of the mixing elements increases from the loading device to the unloading device, wherein the gap between the ends of the mixing elements and the housing in the first half of the housing decreases, and in the second it becomes constant [RU Patent No. 2847594, IPC B01J 2 / 10, published 09.10.2025, BI No. 28].
[0003] The disadvantage of this granulator is the relatively low granulation efficiency, caused by the scattering of material inside the granulator during impact interaction with the mixing elements.
[0004] The closest to the proposed invention is a granulator of powdered media comprising a loading device, an unloading device, a cylindrical body, a rotating shaft installed inside it with mixing elements forming a gap with the cylindrical body, a moistening device, the mixing elements have grooves on the side surfaces. In the mixing elements, through central holes of elliptical cross-section are formed, communicating with the internal cavity of the shaft, which is connected to the gas supply device by means of a flexible pipeline [Patent of the Russian Federation No. 2848076, IPC B01J 2 / 10, published. 16.10.2025, BI No. 29].
[0005] The disadvantage of this granulator is the relatively low granulation efficiency, caused by the scattering of material inside the granulator during impact interaction with the mixing elements.
[0006] The technical result of this invention is to increase the efficiency of granulation.
[0007] The technical result is achieved by the fact that a granulator of bulk components is proposed, containing a loading device, an unloading device, a cylindrical body, a rotating shaft installed inside it with mixing elements that form a gap with the cylindrical body, a moistening device, the mixing elements have central holes.
[0008] Distinctive design features include the fact that the mixing elements are made in a variable shape from hemispherical at the ends, conical in the middle and cylindrical in the area of attachment to the shaft, with the hemispherical and conical sections polished, and the height of the conical sections of the mixing elements located in the area of the humidification device increases from the loading device to the unloading device.
[0009] Fig. 1 shows the diagram of the granulator of bulk components.
[0010] Fig. 2 shows an enlarged view of the mixing element.
[0011] A granulator for bulk components comprises a loading device 1, an unloading device 2, a cylindrical body 3, a rotating shaft 4 installed therein with mixing elements 5 forming a gap with the cylindrical body 3, a moistening device 6, the mixing elements 5 having central holes 7 for fastening to the shaft 4, for example, by means of a thread. The mixing elements 5 are made of a variable shape from hemispherical at the ends, conical in the middle and cylindrical in the area of fastening to the shaft 4, wherein the hemispherical sections are polished. The height of the conical sections of the mixing elements 5, located in the area of the moistening device 6, increases from the loading device 1 to the unloading device 2.
[0012] The bulk component granulator operates as follows. The bulk component to be granulated enters the cylindrical body 3 from loading device 1, where it is captured by mixing elements 5 located on rotating shaft 4. The binder required for granulation is supplied from moistening device 6 and mixed with the bulk material. Repeated action of mixing elements 5 on the material results in the formation of granules, which are discharged from the granulator through discharge device 2.
[0013] The variable shape of the mixing elements 5, ranging from hemispherical at the ends, conical in the middle, and cylindrical where they attach to the shaft 4, improves granulation efficiency. The hemispherical shape of the ends of the mixing elements 5 effectively rolls and compacts the granules in the peripheral section, in the gap with the housing 3. The conical shape creates an impact force directed toward the housing, compacting and strengthening the granules.
[0014] Due to the fact that the hemispherical and conical shaped areas are polished, the material is prevented from sticking to the areas in contact with the material.
[0015] Due to the fact that the height of the conical sections of the mixing elements 5, located in the area of the humidifying device 6, increases from the loading device 1 to the unloading device 2, a changing effect on the granulated material is ensured as it moves along the cylindrical body 3, which improves the quality of mixing with the binder and the efficiency of granulation.
[0016] The proposed design of a granulator for bulk components, with a relatively simple design, will improve the efficiency of granulating bulk media.
