Description

Technical Field

[0001] This invention relates to the field of particulate material preparation technology, and specifically to a high-efficiency processing device for fixed-size particulate filter media. Background Technology

[0002] Disc granulators are widely used granulation equipment in chemical, environmental protection, and metallurgical fields. They use the rotation of a disc to cause powdered materials to roll under the action of centrifugal force, friction, and gravity, and by adding an appropriate amount of liquid binder (such as water), the fine powder is agglomerated into spherical particles.

[0003] Traditional equipment mainly relies on the operator's experience to adjust the disc tilt angle, rotation speed and water volume to control particle size, which makes it difficult to guarantee batch consistency and particle size uniformity, and cannot directly produce finished products with a fixed particle size range. Summary of the Invention

[0004] To overcome the above-mentioned defects, the purpose of this invention is to provide a high-efficiency processing device for fixed-size particle filter media.

[0005] To achieve the above objectives, the present invention provides a high-efficiency processing device for fixed-size particle filter media. Includes a frame, on which a hollow central shaft is fixedly mounted at an angle. A bushing is coaxially fitted around the hollow core shaft via a bearing, and a granulation disc is integrally formed around the bushing. A driving device is connected to the granulation disc to drive the granulation disc to rotate; The granulation disc is equipped with a through sieve, which is fixedly installed on the hollow central shaft, and the outer contour of the through sieve is spaced apart from the inner surface of the granulation disc.

[0006] Furthermore, the edge of the sieve is provided with a scraper for scraping off the material adhering to the inner wall of the granulation disc.

[0007] Furthermore, a water spray pipe is installed inside the hollow core shaft, extending from the hollow core shaft and into the granulation disc.

[0008] Furthermore, the outlet of the water spray pipe is equipped with an atomizing nozzle.

[0009] Furthermore, a hot air duct is installed inside the hollow core shaft, extending from the hollow core shaft and into the granulation disc.

[0010] Furthermore, the inclination angle of the hollow central shaft is 45°.

[0011] Furthermore, a metering pump is installed on the water spray pipeline.

[0012] The present invention has the following advantages: (1) Fixed and controllable particle size: Granulation and screening are carried out simultaneously through a built-in fixed aperture sieve. Only particles with qualified particle size can be screened out, ensuring the high uniformity of product particle size and eliminating the need for subsequent separate screening.

[0013] (2) High efficiency and anti-sticking: The scraper integrated on the screen can continuously scrape off the material stuck to the inner wall as the disc rotates, effectively avoiding material scaling, ensuring stable and continuous operation of the granulation process, and improving production efficiency and product purity.

[0014] (3) Integrated drying: The central heating device can gently dry the particles in the later stage of granulation or during continuous granulation, which shortens the process flow and reduces energy consumption and the risk of particle breakage.

[0015] (4) High degree of automation: The water spray volume and heating temperature can be precisely controlled, which facilitates automated control and improves the stability of product quality. Attached Figure Description

Hollow central shaft Detailed Implementation The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0019] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] like Figure 1 and Figure 2 As shown, the device includes a frame, on which a hollow central shaft 8 is fixedly and inclined. The inclination angle of the hollow central shaft can be set as needed, for example, it can be 15-60°, preferably 45°. A bushing is coaxially fitted around the hollow central shaft via bearings, and a granulation disc 1 is integrally formed around the bushing. A driving device is connected to the granulation disc to drive the granulation disc to rotate; The granulation disc is equipped with a through sieve 7, which is fixedly installed on the hollow central shaft, and the outer contour of the through sieve is spaced apart from the inner surface of the granulation disc.

[0023] Powdered raw materials are fed from one side above the disc and rolled under the action of the rotating disc 1. During the rolling process, the continuously growing particles are screened by the sieve 7 to form filter media of the required particle size.

[0024] As a further improvement of the present invention, a scraper 6 for scraping off material adhering to the inner wall of the granulation disc is provided along the edge of the sieve 7. The scraper can be integrally provided with the sieve 7 or separately provided for easy replacement.

[0025] As a further improvement of the present invention, a water spray pipe is provided inside the hollow core shaft. The water spray pipe extends from the hollow core shaft and into the granulation disc. The outlet of the water spray pipe is provided with an atomizing nozzle. The water mist is evenly sprayed onto the tumbling material bed through the atomizing nozzle 2. Under the action of the water mist, the powder gradually gathers into nuclei and grows.

[0026] As a further improvement of the present invention, a hot air pipe 3 is inserted through the hollow core shaft, extending from the hollow core shaft and into the granulation disc. This allows for low-temperature drying of the particles within the disc, forming dried granular filter material with a certain strength.

[0027] Powdered raw materials are fed from one side above the rotating disc 1 and tumble under its rotation. The water supply unit is activated, and water mist is evenly sprayed onto the tumbling material bed through atomizing nozzles 2. Under the action of the water mist, the powder gradually agglomerates and grows. During the rolling process, the continuously growing particles are sieved through sieve 7 to form filter media of the desired particle size. Scraper 6 continuously scrapes off the wet material adhering to the inner wall of disc 1, returning it to the material bed to continue granulation. In the later stage of granulation, heating device 3 can be activated to dry the particles in the disc at a low temperature, forming dry granular filter media with a certain strength.
