Abstract
Description
Technical Field
[0001] This utility model relates to the field of atomization, and in particular to a centrifugal atomizing disc. Background Technology
[0002] The production process of lithium iron phosphate includes a spraying process and a sintering process. First, the lithium iron phosphate slurry is atomized and dried using an atomizing disc to form lithium iron phosphate powder. Then, the powder is collected in a sintering container for sintering.
[0003] Existing atomizing discs such as Figure 1 As shown, it includes a disc body 1, a disc wall 2 is provided on the top surface of the disc body 1, and a plurality of discharge holes 6 are provided on the disc wall 2. The discharge holes 6 are arranged at equal intervals around the disc body 1. The top of the disc body 1 is covered with a cover body 3, and a through central hole is provided in the middle of the cover body 3. The central hole is the disc body feed port 5. The center of the disc body 1 is connected to the rotating shaft 4.
[0004] During atomization, lithium iron phosphate slurry is injected into the top surface of the disc through the feed port. Then, the rotating shaft drives the disc to rotate. Under the action of centrifugal force, the slurry is sprayed out from the discharge port and atomized into powder.
[0005] To improve sintering efficiency, sintering containers often need to hold as much powder as possible. Generally, larger diameter powders are loaded first. Since there are gaps between the larger diameter powders, smaller diameter powders can be filled into these gaps, thus allowing the sintering container to hold more powder.
[0006] Because the diameter of the discharge port of the current atomizing disc is fixed, it can only produce powder of a fixed diameter under the same centrifugal force. With a fixed volume, the filling amount cannot be effectively increased, resulting in low production capacity.
[0007] Therefore, in order to address the above problems, it is particularly necessary to provide a new atomizing disc that can simultaneously generate powders of different diameters. Utility Model Content
[0008] The purpose of this invention is to provide a centrifugal atomizing disc that addresses the aforementioned problems. This atomizing disc can simultaneously generate powders of two different diameters while maintaining a fixed shaft rotation speed.
[0009] The technical solution adopted in this utility model is as follows:
[0010] A centrifugal atomizing disc includes an upper disc and a lower disc. The diameter of the upper disc is larger than that of the lower disc. A lower disc wall is provided at the outer edge of the top surface of the lower disc, and the lower disc wall surrounds the lower disc. A plurality of radially penetrating lower discharge holes are opened on the lower disc wall, and the lower discharge holes are evenly spaced along the circumference of the lower disc. The upper disc is located above the lower disc, and the center lines of the upper and lower discs coincide. The bottom of the upper disc is fixedly connected to the top of the lower disc wall. An axially penetrating central hole is opened in the middle of the upper disc, and the central hole of the upper disc serves as the feed inlet for the lower disc. An upper disc wall is provided at the outer edge of the top surface of the upper disc, and the upper disc wall surrounds the upper disc. A plurality of radially penetrating upper discharge holes are opened on the upper disc wall, and the upper discharge holes are evenly spaced along the circumference of the upper disc. The center of the lower disc is connected to a rotating shaft.
[0011] Furthermore, an upper plate cover is provided above the upper plate body, and the bottom of the upper plate cover is fixedly connected to the top of the upper plate wall; an axially penetrating central hole is provided in the middle of the upper plate cover, and the central hole of the upper plate cover is the feed port of the upper plate body.
[0012] Furthermore, the diameter of the feed inlet of the lower plate is smaller than the diameter of the lower plate.
[0013] Furthermore, from the center of the lower plate to its edge, the distance between the bottom surface of the upper plate and the top surface of the lower plate gradually decreases.
[0014] Furthermore, the diameter of the feed inlet of the upper plate is larger than the diameter of the lower plate, but smaller than the diameter of the upper plate.
[0015] Furthermore, from the center of the upper plate to its edge, the distance between the bottom surface of the upper plate cover and the top surface of the upper plate gradually decreases.
[0016] Furthermore, a flow-limiting wall is provided on the top surface of the upper plate, and the flow-limiting wall is located at the feed inlet of the lower plate and surrounds the feed inlet of the lower plate.
[0017] Furthermore, the center lines of the upper plate, lower plate, and rotating shaft coincide, the lower end of the rotating shaft is connected to the top surface of the lower plate, and the upper end of the rotating shaft passes through the feed inlet of the lower plate and the feed inlet of the upper plate.
[0018] Furthermore, the centrifugal atomizing disc also includes a feed pipe, which is used to feed slurry from the feed port of the lower disc to the top surface of the lower disc, and to feed slurry from the feed port of the upper disc to the top surface of the upper disc.
[0019] Furthermore, the feed pipe includes a main feed pipe, an upper plate feed pipe, and a lower plate feed pipe; the inlets of the upper plate feed pipe and the lower plate feed pipe are connected to the outlet of the main feed pipe; the outlet of the upper plate feed pipe passes through the upper plate inlet and faces the top surface of the upper plate, and the outlet of the lower plate feed pipe passes through the lower plate inlet and faces the top surface of the lower plate.
[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0021] This invention relates to a centrifugal atomizing disc. Because the diameter of the upper disc is larger than that of the lower disc, the distance from the upper discharge port to the rotating shaft is greater than that from the lower discharge port to the rotating shaft. Therefore, at the same rotational speed, the centrifugal force at the upper discharge port is greater than that at the lower discharge port. During atomization, the slurry is fed to the top surfaces of both the upper and lower discs. As the shaft rotates, the centrifugal force causes both discharge ports to simultaneously produce powder. The upper discharge port produces powder with a smaller diameter, while the lower discharge port produces powder with a relatively larger diameter. This centrifugal atomizing disc can simultaneously produce two different diameter powders, resulting in significantly improved production efficiency. Attached Figure Description

[0032] like Figures 2-3As shown, a centrifugal atomizing disc includes an upper disc body 9 and a lower disc body 7; the diameter of the upper disc body 9 is larger than the diameter of the lower disc body 7; a lower disc wall 8 is provided at the outer edge of the top surface of the lower disc body 7, and the lower disc wall 8 surrounds the lower disc body 7; a plurality of radially penetrating lower discharge holes 16 are opened on the lower disc wall 8, and the lower discharge holes 16 are equally spaced around the lower disc body 7; the upper disc body 9 is located above the lower disc body 7, and the center lines of the upper disc body 9 and the lower disc body 7 coincide; the upper disc body 9... The bottom of the disc body 9 is fixedly connected to the top of the lower disc wall 8; the middle of the upper disc body 9 is provided with an axially penetrating central hole, which is the feed inlet 12 of the lower disc body; an upper disc wall 10 is provided at the outer edge of the top surface of the upper disc body 9, which wraps around the upper disc body 9; a plurality of radially penetrating upper discharge holes 15 are provided on the upper disc wall 10, which are equally spaced around the upper disc body 9; the center of the lower disc body 7 is connected to the rotating shaft 4.
[0033] In the above structure, since the diameter of the upper disc 9 is larger than the diameter of the lower disc 7, the distance from the upper discharge port 15 to the rotating shaft 4 is greater than the distance from the lower discharge port 16 to the rotating shaft 4. Therefore, at the same rotation speed, the centrifugal force at the upper discharge port 15 is greater, and the centrifugal force at the lower discharge port 16 is smaller. During atomization, the slurry is fed to the top surfaces of the upper disc 9 and the lower disc 7 respectively. As the rotating shaft 4 rotates, under the action of centrifugal force, both discharge ports can generate powder simultaneously. The upper discharge port can generate powder with a smaller diameter, and the lower discharge port can generate powder with a relatively larger diameter.
[0034] The centrifugal atomizing disc of this invention can simultaneously produce two powders of different diameters, thereby greatly improving production efficiency.
[0035] Furthermore, an upper plate cover 14 is provided above the upper plate body 9, and the bottom of the upper plate cover 14 is fixedly connected to the top of the upper plate wall 10; a through center hole is provided in the middle of the upper plate cover 14, and the center hole of the upper plate cover 14 is the upper plate body feed port 11.
[0036] The presence of the upper cover 14 prevents the slurry from splashing out of the entire atomizing disc during atomization.
[0037] Furthermore, the diameter of the feed inlet 12 of the lower disc is smaller than the diameter of the lower disc 7. This can provide some shielding for the slurry and prevent slurry splashing. From the center to the edge of the lower disc 7, the distance between the bottom surface of the upper disc 9 and the top surface of the lower disc 7 gradually decreases; due to the reduced cross-sectional area, the flow velocity increases, which can accelerate the flow of the slurry to the downward discharge port, further ensuring the atomization effect.
[0038] Furthermore, the diameter of the upper disc inlet 11 is larger than the diameter of the lower disc 7 but smaller than the diameter of the upper disc 9. This provides some shielding for the slurry, preventing splashing. From the center to the edge of the upper disc 9, the distance between the bottom surface of the upper disc cover 14 and the top surface of the upper disc 9 gradually decreases. Due to the reduced cross-sectional area, the flow velocity increases, accelerating the upward flow of the slurry to the outlet and further ensuring the atomization effect.
[0039] Furthermore, a flow-limiting wall 13 is provided on the top surface of the upper plate 9. The flow-limiting wall 13 is located at the feed inlet 12 of the lower plate and surrounds the feed inlet 12 of the lower plate. Due to the presence of the flow-limiting wall 13, the slurry on the upper plate 9 can be prevented from flowing back into the lower plate 7.
[0040] Furthermore, the center lines of the upper disc 9, lower disc 7, and rotating shaft 4 coincide, the lower end of the rotating shaft 4 is connected to the top surface of the lower disc 7, and the upper end of the rotating shaft 4 passes through the feed inlet 12 of the lower disc and the feed inlet 11 of the upper disc. The rotating shaft 4 is located within the entire atomizing disc, which can reduce the volume of the atomizing disc and make the structure of the entire atomizing disc more compact.
[0041] Furthermore, the centrifugal atomizing disc also includes a feed pipe, which is used to feed the slurry from the feed port 12 of the lower disc to the top surface of the lower disc 7, and to feed the slurry from the feed port 11 of the upper disc to the top surface of the upper disc 9.
[0042] Furthermore, the feed pipe includes a main feed pipe 17, an upper plate feed pipe 18, and a lower plate feed pipe 19; the inlets of the upper plate feed pipe 18 and the lower plate feed pipe 19 are connected to the outlet of the main feed pipe 17; the outlet of the upper plate feed pipe 18 passes through the upper plate feed inlet 11 and faces the top surface of the upper plate 9, and the outlet of the lower plate feed pipe 19 passes through the lower plate feed inlet 12 and faces the top surface of the lower plate 7.
[0043] The presence of the upper plate feed pipe 18 and the lower plate feed pipe 19 enables more accurate delivery of the slurry to the target position.
[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
