Description

Technical Field

[0001] This utility model relates to the field of particle classification equipment technology, and in particular to a guide vane type coarse and fine particle classification hydrocyclone. Background Technology

[0002] In many industrial sectors such as mining, building materials, chemicals, and environmental protection, efficient and precise coarse and fine classification of solid particulate materials is a key step in ensuring the smooth progress of subsequent processes and improving product quality. For example, in mineral processing, classification can send mineral particles of qualified size to subsequent separation operations, reducing ineffective energy consumption. In building material production, classification can ensure uniform particle size of raw materials and improve product performance. In the field of solid waste treatment, classification helps to realize the resource utilization of materials with different particle sizes.

[0003] Existing hydrocyclones mainly use guide vanes to stabilize the flow field, thereby optimizing the particle trajectory, reducing backmixing, and improving the accuracy and efficiency of coarse and fine particle classification.

[0004] However, during long-term operation, the existing guide vanes will gradually wear down, become blunt at the edges, or even deform locally due to the continuous scouring and friction of high-concentration particulate materials. This will damage the original flow field guiding structure, leading to unstable fluid swirl intensity and increased turbulence disturbance. Consequently, the particle trajectory will deviate from the design path, the boundary between coarse and fine particle classification will become blurred, and back mixing will increase. This will not only affect the continuity and stability of the classification operation but also reduce the classification efficiency of the equipment. Utility Model Content

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1: Refer to Figure 1 - Figure 5 As shown: A guide vane type coarse and fine particle classifying hydrocyclone includes a hydrocyclone body 1;

[0027] Quick-release component 2 is located on top of the hydrocyclone body 1;

[0028] The quick-release assembly 2 includes a U-shaped frame 201, a mounting block 206, and a set of positioning pins 212. A servo motor 202 is fixedly mounted on the top of the U-shaped frame 201. The output end of the servo motor 202 slides through the top of the U-shaped frame 201 and extends downwards. A connecting rod 203 is fixedly mounted on the output end of the servo motor 202. A mounting shell 204 is fixedly connected to the bottom of the connecting rod 203. A fixing groove 205 is formed on the outer surface of the mounting shell 204. A rotating ring 207 is fixedly connected to the bottom of the mounting block 206. Triangular grooves 208 are formed on both outer surfaces of the mounting block 206. Triangular blocks are slidably connected to the inner walls of each set of triangular grooves 208. 209, a set of triangular blocks 209 are all provided with springs 210 on the outside, the inner wall of the mounting shell 204 is slidably connected to the outer surface of the mounting block 206, a set of triangular blocks 209 are all fixedly connected to the outer surface of the sliding block 211, the outer surface of the sliding block 211 is slidably connected to the inner wall of the fixing groove 205, the bottom of a set of positioning pins 212 slides through the top of the mounting shell 204 and the sliding block 211 and extends to one side, the bottom of the U-shaped frame 201 is fixedly installed to the top of the hydrocyclone body 1, the bottom of the mounting shell 204 is rotatably connected to the top of the hydrocyclone body 1, and the outer surface of the rotating ring 207 is rotatably connected to the inner wall of the hydrocyclone body 1.

[0029] In this embodiment, when the guide vanes of the guide vane type coarse and fine particle classifying hydrocyclone need to be replaced after long-term operation, the positioning pin 212 must be operated first. The positioning pin 212 is a key component used to fix the sliding block 211. At this time, it needs to be pulled out from the corresponding pin hole. As the positioning pin 212 is pulled out, its fixing effect on the sliding block 211 is released. The sliding block 211 was originally embedded in the fixing groove 205. After the fixing is released, the sliding block 211 can be pulled out along the trajectory of the fixing groove 205. During the movement of the sliding block 211, the triangular block 209 connected to it will gradually enter the fixing groove 205 with the movement of the sliding block 211. The triangular block 209 was previously in the triangular groove 2 of the mounting block 206. Within 08, this serves to fix the mounting block 206. When the triangular block 209 enters the fixing groove 205, its clamping state on the mounting block 206 is broken, and the fixing of the mounting block 206 is released. The mounting block 206 is connected to the rotating ring 207 and the blade rod 3. After the mounting block 206 is released, under its own weight, the mounting block 206 will drive the rotating ring 207 and the blade rod 3 to fall out of the hydrocyclone body 1, thus completing the disassembly of the old blade rod 3. Next, the new blade rod 3 is installed. According to the position and size of the groove at the top of the hydrocyclone body 1, the new blade rod 3, together with the mounting block 206 and the rotating ring 207, is installed in place. During the installation process, the mounting block... The top of 206 will contact and compress the triangular block 209. This compressive force will cause the triangular block 209 to move into the fixing groove 205. As the installation continues, when the triangular groove 208 on the mounting block 206 and the triangular block 209 are aligned, the triangular block 209 will quickly spring into the triangular groove 208 under the elastic force of the spring 210, thus re-fixing the mounting block 206. At this time, the positioning pin 212 is inserted into the corresponding pin hole again to re-fix the sliding block 211, ensuring the stability of the entire installation structure. After the installation is completed, the servo motor 202 installed on the top of the U-shaped frame 201 is started. 2. After startup, its output end will drive the connecting rod 203 to start rotating. The connecting rod 203 is connected to the mounting shell 204. Therefore, the rotation of the connecting rod 203 will drive the mounting shell 204 to rotate synchronously, thereby causing the rotating ring 207 to rotate along a predetermined trajectory on the inner wall of the hydrocyclone body 1. During the rotation of the rotating ring 207, the blade rod 3 connected to it will rotate together with the rotating ring 207. At this time, the hydrocyclone enters the working state and begins to classify coarse and fine particles. With the action of the quick disassembly component 2, the guide blades can be disassembled, thereby effectively reducing the operational failures caused by blade wear. This not only ensures the continuity and stability of the classification operation, but also improves the classification efficiency of the equipment.

[0030] Example 2: According to Figure 1 - Figure 5 As shown: A blade rod 3 is fixedly installed at the bottom of the rotating ring 207. A water inlet pipe 31 and a ore inlet pipe 32 are fixedly connected to both sides of the hydrocyclone body 1, respectively. A base ring 33 is fixedly installed on the inner wall of the hydrocyclone body 1 near the bottom. A set of fine particle pipes 34 are symmetrically connected to the bottom of the base ring 33. A valve 35 is provided on the outside of each set of fine particle pipes 34. A connecting plate 36 is fixedly installed on the inner wall of the base ring 33. A threaded cap 37 is threadedly connected to the outside of the connecting plate 36. A circular screen 4 is fixedly installed on the top of the hydrocyclone body 1. A limit groove 41 is opened on the top of the hydrocyclone body 1. A set of limit blocks 42 are rotatably connected to the inner wall of the limit groove 41. The top of the set of limit blocks 42 is fixedly connected to the bottom of the mounting shell 204.

[0031] In this embodiment, during the rotation of the rotating ring 207, the blade rod 3 connected to it rotates together with the rotating ring 207. At this time, the hydrocyclone enters the working state. During operation, slurry is added into the hydrocyclone through the ore inlet pipe 32. As the blade rod 3 continues to rotate, the coarse and fine particles in the slurry are classified under the action of the high-speed rotating blades. The fine particles of slurry pass through the ring screen 4 and fall into the base ring 33 below. At this time, the corresponding valve 35 is activated, and the fine particles of slurry can be discharged from the fine particle pipe 34, while the coarse particles of slurry remain inside the connecting plate 36. After accumulating to a certain amount, the threaded cover 37 on the connecting plate 36 is opened to discharge the coarse particles of slurry, completing the classification of coarse and fine particles. Subsequently, water is added through the water inlet pipe 31 for cleaning. During the rotation of the mounting shell 204, the limiting block 42 at its bottom rotates along the limiting groove 41. The cooperation between the limiting block 42 and the limiting groove 41 further ensures the stability of the entire rotating structure during operation.

[0032] Working principle: When the guide vanes of the guide vane type coarse and fine particle classifier hydrocyclone need to be replaced, first pull out the positioning pin 212, and the sliding block 211 is released from its fixation. The sliding block 211 was originally embedded in the fixing groove 205. After the fixation is released, it can be pulled out along the groove. The triangular block 209 connected to it gradually enters the fixing groove 205 as it moves. After entering the fixing groove 205, the mounting block 206 is released from its fixation. Then, under its own weight, it drives the rotating ring 207 and the blade rod 3 to fall off from the hydrocyclone body 1, completing the disassembly of the old blade rod 3. When installing the new blade rod 3, the top of the mounting block 206 presses the triangular block 209 to make it enter the fixing groove 205. When the triangular groove 208 is aligned with the triangular block 209, the elastic force of the spring 210 makes the triangular block 209 spring into the triangular groove 205. 08, then fix the mounting block 206, and then insert the positioning pin 212 to fix the sliding block 211. Subsequently, start the servo motor 202 to drive the mounting shell 204 to rotate, which in turn causes the rotating ring 207 to rotate along the inner surface of the hydrocyclone body 1. When the mounting shell 204 rotates, the bottom limit block 42 rotates along the limit groove 41 to ensure stability. The rotating ring 207 drives the blade rod 3 to rotate, and the hydrocyclone enters the working state. During operation, slurry is added to the ore inlet pipe 32. The rotation of the blade rod 3 causes the coarse and fine particles in the slurry to be classified. The fine particles of slurry pass through the circular screen 4 and fall to the base ring 33. The valve 35 is started to discharge from the fine particle pipe 34. The coarse particles of slurry remain in the connecting plate 36. After accumulation, the threaded cover 37 is opened to discharge. After operation, water is added through the water inlet pipe 31 for cleaning.

[0033] By following the steps outlined above, you can successfully use the guide vane type coarse and fine particle classifier hydrocyclone.
