Description

Technical Field

[0001] The invention belongs to the technical field of beryllium smelting slurry separation, and in particular relates to a high-efficiency cyclone. Background Art

[0002] In the beryllium smelting process, beryl and calcite are first mixed in a certain proportion and then melted in an electric arc furnace to destroy the crystal form of beryl, making it easy to react with sulfuric acid and convert into sulfate. After the melt is smelted and quenched with water, the coarse beryllium glass produced is ground into fine beryllium glass in a wet ball mill and directly enters the centrifuge for dehydration to obtain dry fine beryllium glass. However, the fineness of the obtained fine beryllium glass is often unqualified, resulting in a low beryllium leaching rate, which affects the recovery rate of beryllium. The efficient smelting method is to install a high-efficiency cyclone for inspection and classification before the fine beryllium glass enters the centrifuge for dehydration. Only qualified particle sizes can enter the centrifuge for dehydration through the overflow of the cyclone to obtain qualified fine beryllium glass. Unqualified coarse particle sizes are returned to the ball mill through the sand settling nozzle, and the ball milling continues to form a closed loop.

[0003] At present, the existing cyclone announcement number is CN107866336B, which includes a conical shell with a cylindrical shell body, a feeding port and an overflow port are arranged on the cylindrical shell body, and a conical bottom with a discharge port is arranged at the lower part of the cylindrical shell body. The tangential direction of the feeding port is connected to the cavity in the cylindrical shell body, and an anti-blocking protection structure is arranged at the discharge port. By arranging the anti-blocking protection structure at the discharge port, the attached debris can be automatically cleaned after the attached matter reaches a certain amount, and the function of automatically cleaning the deposits at the feed port can be achieved. It can not only prevent the accumulation of attached matter from causing equipment failure and reduce labor costs, but also has a simple structure and is easy to operate.

[0004] But there is also a problem: there is no collection device at the discharge pipe, and due to the initial feed pressure of the cyclone and the structural problems of the cyclone itself, some light slurry will still flow out of the discharge pipe, which may easily lead to the waste of some small slurry. Summary of the invention

[0005] This solution provides a high-efficiency cyclone to solve the problem of insufficient slurry purity in the discharge pipe.

[0006] The present invention provides a high-efficiency cyclone, comprising a cylindrical shell; an overflow pipe: the overflow pipe is connected to the cylindrical shell; a feed pipe: the feed pipe is connected to the cylindrical shell, and the feed pipe and the cylindrical shell are tangentially arranged; a feed pump: the feed pump is connected to the feed pipe; a vertebral body: the vertebral body is fixedly connected to the cylindrical shell; a discharge pipe: the discharge pipe is connected to the vertebral body; and also includes a secondary grading mechanism, the secondary grading mechanism comprising: a collecting box: the collecting box is connected to the discharge pipe; a secondary grading trough: the secondary grading trough is fixedly connected to the collecting box; a filter plate, the filter plate cooperates with the secondary grading trough, and the filter plate cooperates with the discharge pipe.

[0007] The principle of this scheme is that the operator starts the feed pump and feeds the fine beryllium glass to be separated into the cylindrical shell through the feed pipe at a set flow rate. At this time, the slurry will rotate in the cylindrical shell to generate centrifugal force, and then pass through the vertebral body. The heavier material will be pushed to the outer wall of the cyclone, while the lighter material will move to the center. Similar to the principle of a tornado, the lighter slurry will move from the center to the overflow pipe and overflow, while the heavier slurry will slowly sink from the edge, then go out from the discharge pipe and come to the collection box to complete the screening.

[0008] Due to the initial feed pressure of the cyclone and the structural problems of the cyclone itself, some of the slurry with small weight will still flow out of the discharge pipe. In order to avoid this part of waste and to perform secondary classification and screening, this solution sets up a secondary classification tank. When the slurry flows out of the discharge pipe, it will fall on the filter plate, and the filter plate will perform secondary screening. This mechanism improves the screening efficiency.

[0009] The beneficial effect of this solution is that the solution collects unqualified beryllium through the collection box, which is convenient for collecting it for re-milling. At the same time, the collection box can also prevent the slurry from splashing out.

[0010] Furthermore, the filter plate is conical, and the conical structure can make large particles of ore pulp that cannot enter the filter plate slide off the filter plate, thereby preventing the large particles of ore pulp from clogging the filter plate.

[0011] Furthermore, it also includes a cleaning mechanism, which includes a cleaning rod, a spring and a rubber ring. The cleaning rod is fixedly connected to the filter plate, and the cleaning rod cooperates with the discharge pipe. The filter plate is fixedly connected to the secondary grading groove through a rubber ring, and the rubber ring is a retractable rubber ring. One end of the spring is fixedly connected to the secondary grading groove, and the other end is fixedly connected to the filter plate.

[0012] When the discharge pipe is blocked, the impact of the water flow weakens, the spring makes the filter plate move up, and the filter plate moves up to drive the cleaning rod to move up, and the cleaning rod scrapes the wall of the discharge pipe. When the discharge pipe is not blocked, the impact of the water flow will cause the filter plate to move down, and the filter plate moving down will cause the cleaning rod to move down and scrape the wall again. This solution enables the cleaning rod to automatically scrape the discharge pipe in operation. The discharge pipe can be cleaned without stopping the machine, which improves the efficiency of the entire device. At the same time, the filter plate can shake out impurities blocked in the filter hole by shaking up and down to prevent the filter plate from being blocked.

[0013] Furthermore, the device further comprises a limit block, which is fixedly connected to the discharge pipe and matched with the cleaning rod. The limit block can prevent the cleaning rod from being separated from the discharge pipe, causing the device to fail.

[0014] Furthermore, it also includes a rotating mechanism, which includes a threaded sleeve and a threaded rod. The threaded sleeve is fixedly connected to the secondary grading groove, the threaded rod is fixedly connected to the cleaning rod, and the threaded sleeve is threadedly connected to the threaded rod.

[0015] When the discharge pipe is blocked, the water flow impact becomes smaller, the spring makes the filter plate move up, and the threaded rod moves up. When the threaded rod moves up, it will rotate due to the threaded connection with the threaded sleeve. The rotation of the threaded rod will drive the filter plate to rotate, and the rotation of the filter plate will drive the cleaning rod to rotate, so that the cleaning rod can clean more places, improving the cleaning efficiency.

[0016] Furthermore, the feed pipe and the overflow pipe are both detachably fixedly connected to the cylindrical shell by fixing bolts. The detachable connection facilitates the operator to clean the feed pipe and the overflow pipe. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] Basically as attached Figure 4 As shown: The beryllium smelting process includes: in the beryllium smelting process, beryl and calcite are first mixed in a certain proportion, and then melted in an electric arc furnace to destroy the crystal shape of beryl, making it easy to react with sulfuric acid and convert into sulfate.

[0020] After the melt is smelted and quenched with water, the coarse beryllium glass produced is ground into fine beryllium glass in a wet ball mill and directly enters the centrifuge for dehydration to obtain dry fine beryllium glass. Before the fine beryllium glass enters the centrifuge for dehydration, a high-efficiency cyclone is installed for inspection and grading. Only qualified particle sizes can enter the centrifuge for dehydration through the overflow of the cyclone to obtain qualified fine beryllium glass. Unqualified coarse particle sizes are returned to the ball mill through the sand settling nozzle and continue to be ball milled to form a closed cycle.

The cylindrical shell is vertically connected to the feed pipe 4, the feed pipe 4 is connected to the feed pump, the overflow pipe 3 is fixedly connected to the top of the cylindrical shell by a fixing bolt 2, the vertebral body 1 is coaxially connected to the bottom of the cylindrical shell, the discharge pipe 5 is connected to the lower part of the vertebral body 1, the collecting box 7 is connected to the discharge pipe 5, the secondary classification tank 8 is located inside the collecting box 7, and the secondary classification tank 8 is located directly below the discharge pipe 5.

[0022] As attached Figure 1 , Figure 3 As shown: A load-bearing plate 18 is provided at the opening of the secondary classification tank 8. The load-bearing plate 18 is a hollow structure. Two filter plates 15 are provided. The two filter plates 15 are fixedly connected by a connecting plate 12. The two filter plates 15 are conical, and the filter plates 15 are fixedly connected to the secondary classification tank 8 by a rubber ring 16. The rubber ring 16 has the function of being stretchable and rotatable. The connecting plate 12 is parallel to the load-bearing plate 18.

[0023] There are two springs 17, one end of which is fixedly connected to the bearing plate 18, and the other end is fixedly connected to the connecting plate 12. There are two cleaning rods 10, which are fixed to both ends of the fixing plate 11 through the fixing plate 11, and the two cleaning rods 10 are slidably connected to the inner wall of the discharge pipe 5, and the heights of the two cleaning rods 10 are consistent. A threaded rod 13 is provided at the center of the fixing plate 11, and a threaded sleeve 14 is provided on the bearing plate 18, and the threaded rod 13 and the threaded sleeve 14 are threadedly connected. The discharge pipe 5 is also provided with two limit blocks 9 corresponding to the cleaning rods 10, and the limit blocks 9 are used to limit the travel of the cleaning rods 10. The fixing plate 11 is rotatably connected to the connecting plate 12.

[0024] As attached Figure 1 , Figure 2 , as shown in 3: The principle of this scheme is that the operator starts the feed pump and feeds the fine beryllium glass to be separated into the cylindrical shell through the feed pipe 4 at a set flow rate. At this time, the slurry will rotate in the cylindrical shell to generate centrifugal force, and then pass through the vertebral body 1. The heavier material will be pushed to the outer wall of the cyclone, while the lighter material will move to the center. Similar to the principle of a tornado, the lighter slurry will move from the center to the overflow pipe 3 and overflow, while the heavier slurry will slowly sink from the edge, and then go out from the discharge pipe 5 and come to the collection box 7 to complete a screening.

[0025] The ore pulp coming out of the discharge pipe 5 will impact the fixed plate 11, and then roll down to the filter plate 15, and the filter plate 15 performs secondary classification filtration. The filtered ore pulp will pass through the load-bearing plate 18 and fall into the secondary classification tank 8.

[0026] When the discharge pipe 5 is blocked, the impact of the water flow is weakened, and the spring 17 makes the filter plate 15 move up, and the filter plate 15 moves up to drive the cleaning rod 10 to move up, and the cleaning rod 10 scrapes the wall of the discharge pipe 5. At the same time, the fixed plate 11 moves up to make the threaded rod 13 move up, and when the threaded rod 13 moves up, it will rotate due to the threaded connection with the threaded sleeve 14, and the rotation of the threaded rod 13 will drive the filter plate 15 to rotate, and the rotation of the filter plate 15 will drive the cleaning rod 10 to rotate, so that the cleaning rod 10 can clean more places. The pitch of the threaded sleeve and the threaded rod is relatively large, and lubricating oil is also provided between the threaded rod and the threaded sleeve to ensure that the threaded rod can be easily rotated.

[0027] When the discharge pipe 5 is not blocked, the impact of the water flow will cause the filter plate 15 to move downward, and the downward movement of the filter plate 15 will cause the cleaning rod 10 to move downward to scrape the pipe wall again. This solution enables the cleaning rod 10 to automatically scrape the discharge pipe 5 that is in operation. The discharge pipe 5 can be cleaned without stopping the machine, thereby improving the efficiency of the entire device. At the same time, the filter plate 15 can shake out impurities blocked in the filter hole by shaking up and down, thereby preventing the filter plate 15 from being blocked.

[0028] The beneficial effects of this solution are as follows: 1. This solution collects unqualified beryllium through the collection box 7, which is convenient for collecting it for re-milling. At the same time, the collection box 7 can also prevent the slurry from splashing out. 2. This solution also performs secondary screening, which improves the efficiency of the cyclone. 3. The discharge pipe 5 can be cleaned without stopping the machine, which improves the efficiency of the entire device. At the same time, the filter plate 15 can shake out the impurities blocked in the filter hole by shaking up and down, preventing the filter plate 15 from clogging. 4. The cleaning rod 10 rotates and rises for cleaning, so that the cleaning rod 10 can clean more places, improving the cleaning efficiency.
