Description

Technical Field

[0001] This utility model belongs to the field of slag powder production and processing technology, specifically, it relates to an eddy current ultrafine separator. Background Technology

[0002] The eddy current ultrafine separator for slag powder production and processing is an ultrafine separation device specifically designed for the production of slag powder.

[0003] The prior art discloses a pneumatic vortex separator (CN211756859U). The separator includes a feed inlet, a separation chamber, a drive motor, a discharge cone, a discharge outlet, a fine ash outlet, a secondary air inlet, a ash guide cylinder, a separation impeller, and a pneumatic enhancement device. The separation chamber is arranged vertically and is hollow inside. The discharge cone is tightly connected to the bottom of the hollow separation chamber, and the discharge outlet is coaxially and tightly connected to the bottom of the discharge cone. The pneumatic enhancement device is added to the separation chamber of this separator. The material is subjected to a strong swirling effect of airflow in the enhancement device, and the material and airflow are mixed more evenly, improving the material dispersion effect, reducing the probability of back mixing of coarse and fine particles, further improving the separation efficiency, reducing the circulation of material in the separation chamber, and reducing power loss.

[0004] Research revealed that existing technologies, when used, cannot prevent powder return when the powder concentration of the material to be separated is high. Furthermore, in the separation of slag, the large gaps between the planar blades in existing technologies result in less centrifugal force, which is not conducive to airflow and thus affects vortex formation. This can easily lead to powder and some lighter slag being blown back to the feed inlet when the airflow is too strong, causing back-mixing and affecting the efficiency of ultrafine separation. Additionally, the overly tight connections between devices hinder installation and disassembly, making maintenance difficult.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the aforementioned technical problems of powder backmixing and its impact on sorting efficiency, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] An eddy current ultra-fine separation machine, including

[0008] A fixed frame, in which a sorting barrel is fixedly installed, a barrel cover is installed on the sorting barrel, and a guide pipe is fixedly provided on the bottom surface of the barrel cover;

[0009] The sorting mechanism includes a grading wheel, a guide fan, a guide fan, a rotating shaft, a material distribution plate, and a filter ring. The filter ring is fixedly installed inside the sorting barrel. The material distribution plate is fixedly disposed between the rotating shaft and the grading wheel. The guide fan and the guide fan are both fixedly disposed on the curved surface of the rotating shaft. The rotating shaft is rotatably disposed at the bottom of the barrel cover.

[0010] In a preferred embodiment of this utility model, a coarse powder discharge pipe is provided at the bottom of the sorting barrel, a spiral fine powder discharge pipe is provided above the sorting barrel, a feed pipe for feeding is provided at the top of the barrel cover, the guide pipe is a Y-shaped pipe, the feed pipe and the guide pipe are connected, and the sorting barrel is connected to the coarse powder discharge pipe and the fine powder discharge pipe.

[0011] In a preferred embodiment of this utility model, an air inlet pipe is provided in the middle of the sorting barrel, and a conical filter ring is fixedly installed inside the middle of the sorting barrel. The air inlet pipe corresponds to the filter ring and is connected to the sorting barrel.

[0012] In a preferred embodiment of this utility model, the barrel cover is fixedly installed on the top surface of the sorting barrel by bolts, and a high-speed motor is fixedly installed on the top surface of the barrel cover. The output end of the high-speed motor is connected to the top surface of the rotating shaft.

[0013] In a preferred embodiment of this utility model, the classifying wheel is a V-shaped tubular structure, the classifying wheel is fixedly connected to the material distribution disc, the material distribution disc is fixedly connected to the rotating shaft, the classifying wheel is coaxially wrapped around the fine powder discharge pipe, and the guide pipe is rotatably connected to the classifying wheel.

[0014] In a preferred embodiment of this utility model, the material distribution disc is disposed between the grading wheel and the guide fan, the guide fan is disposed between the material distribution disc and the guide fan, and the guide fan is rotatably disposed within the filter ring.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. By setting up a sorting mechanism, the guide fan directs the airflow entering from the air inlet pipe into the sorting barrel. The guide fan agitates the airflow, forming a centrifugal vortex. At this time, the slag is sorted by the conical classifying wheel. The lighter slag powder is discharged through the fine powder discharge pipe, while the larger and heavier slag powder falls from the coarse powder discharge pipe through gravity and centrifugal vortex.

The classifying wheel is surrounded between the fine powder discharge pipe and the guide pipe, and the material distribution plate is located between the guide pipe and the classifying wheel, isolating the path of slag back mixing, and at the same time providing guidance for the fine powder discharge, thereby avoiding slag back mixing to a certain extent and improving the sorting effect.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] An eddy current ultra-fine separation machine, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the system includes a fixed frame 10, within which a sorting barrel 11 is fixedly installed. A barrel cover 14 is mounted on the sorting barrel 11, and a guide pipe 21 is fixedly installed on the bottom surface of the barrel cover 14. A sorting mechanism is also included, comprising a grading wheel 18, a guide fan 19, a guide fan 20, a rotating shaft 22, a material distribution plate 23, and a filter ring 24. The filter ring 24 is fixedly installed inside the sorting barrel 11. The material distribution plate 23 is fixedly positioned between the rotating shaft 22 and the grading wheel 18. Both the guide fan 19 and the guide fan 20 are fixedly mounted on the curved surface of the rotating shaft 22, which is rotatably positioned at the bottom of the barrel cover 14. Figure 1 , Figure 2 and Figure 4 As shown, a coarse powder discharge pipe 13 is provided at the bottom of the sorting barrel 11, a spiral fine powder discharge pipe 16 is provided above the sorting barrel 11, a feed pipe 15 for feeding is provided at the top of the barrel cover 14, the guide pipe 21 is a Y-shaped pipe, the feed pipe 15 and the guide pipe 21 are connected, and the sorting barrel 11 is connected to the coarse powder discharge pipe 13 and the fine powder discharge pipe 16.

[0029] Specifically, this device employs a sorting mechanism. The guide fan 20 directs the airflow from the inlet pipe 12 into the sorting barrel 11, while the guide fan 19 agitates the airflow, creating a centrifugal vortex. The slag is then sorted by the conical classifying wheel 18. Lighter slag particles are discharged through the fine powder discharge pipe 16, while larger and heavier slag particles fall from the coarse powder discharge pipe 13 due to gravity and the centrifugal vortex. This not only solves the problem of large gaps between planar blades affecting vortex formation in existing technologies but also improves the efficiency of ultrafine sorting. The classifying wheel 18 surrounds the fine powder discharge pipe 16 and the guide pipe 21, while the material distribution plate 23 is located between the guide pipe 21 and the classifying wheel 18, isolating the path of slag back-mixing and guiding the fine powder discharge. This, to a certain extent, avoids slag back-mixing and improves the sorting effect. By placing the sorting mechanism below the barrel cover 14, the device is easier to disassemble and install, facilitating frequent maintenance and cleaning.

[0030] like Figure 2 and Figure 4 As shown, an air inlet pipe 12 is provided in the middle of the sorting barrel 11, and a conical filter ring 24 is fixedly installed inside the middle of the sorting barrel 11. The air inlet pipe 12 corresponds to the filter ring 24 and is connected to the sorting barrel 11; Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the barrel cover 14 is fixedly installed on the top surface of the sorting barrel 11 by bolts. A high-speed motor 17 is fixedly installed on the top surface of the barrel cover 14, and the output end of the high-speed motor 17 is connected to the top surface of the rotating shaft 22; Figure 4As shown, the classifying wheel 18 has a V-shaped tubular structure. The classifying wheel 18 is fixedly connected to the material distribution disc 23, and the material distribution disc 23 is fixedly connected to the rotating shaft 22. The classifying wheel 18 is coaxially arranged within the fine powder discharge pipe 16, and the guide pipe 21 is rotatably connected within the classifying wheel 18. Figure 4 and Figure 5 As shown, the material distribution plate 23 is disposed between the classifier wheel 18 and the guide fan 19, the guide fan 19 is disposed between the material distribution plate 23 and the guide fan 20, and the guide fan 20 is rotatably disposed within the filter ring 24; Figure 5 As shown, the guide fan 19 is composed of multiple vortex blades, and the guide fan 20 is composed of multiple fan-shaped blades. The vortex blades are spirally arranged on the curved surface of the rotating shaft 22, and the fan-shaped blades are vertically arranged on the curved surface of the rotating shaft 22.

[0031] Specifically, during use, the high-speed motor 17 is started, driving the rotating shaft 22 to rotate at high speed. The rotating shaft 22 drives the classifying wheel 28, which is connected between the fine powder discharge pipe 16 and the guide pipe 21, to rotate at high speed. At the same time, the rotating shaft 22 drives the material distribution plate 23, the guide fan 19, and the guide fan 20 to rotate at high speed. At this time, the external ventilation device is connected to the air inlet pipe 12, and the airflow enters the sorting barrel 11 through the filter ring 24. At this time, the slag is poured in from the feed pipe 15. The slag then passes through the guide... Pipe 21 falls onto the material distribution plate 23, and the slag is moved by the material distribution plate 23. At the same time, the guide fan 20 drives the airflow to form a spiral upward airflow. Then the airflow passes through the guide fan 19, and under the centrifugal force of the guide fan 19, a vortex spiral is formed, which wraps the slag. At this time, the heavier slag falls out from the coarse powder discharge pipe 13 under the action of the vortex spiral, while the lighter slag powder enters the classifier wheel 18 through the vortex spiral, and then enters the fine powder discharge pipe 16 through the classifier wheel 18 and is discharged.
