Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cubic boron nitride extraction, and particularly relates to a device for extracting cubic boron nitride tailings. Background Art
[0002] First of all, the preparation of cubic boron nitride usually involves a synthesis process under high temperature and high pressure conditions. The raw materials are mainly hexagonal boron nitride (h-BN) and catalysts (such as alkali metals, alkaline earth metals, etc.). In this process, the raw materials are subjected to specific temperature and pressure treatments, and a phase change occurs, transforming from a hexagonal structure to a cubic structure to form cubic boron nitride.
[0003] However, in industrial production, due to the influence of various factors such as raw material purity, reaction condition control, and equipment efficiency, not all raw materials can be completely converted into cubic boron nitride. Therefore, during the production process, some raw materials that have not been completely converted, reaction by-products, and possible impurities are generated, and these substances can be regarded as "tailings" or "waste materials".
[0004] When extracting the tailing particles in cubic boron nitride, the existing method is to remove the impurities in the tailings of cubic boron nitride by hydrochloric acid or acidic solution, so as to extract relatively pure hexagonal boron nitride.
[0005] Although the above equipment can extract the tailings of cubic boron nitride, because the larger cubic boron nitride tailing particles will precipitate to the bottom of the hydrochloric acid solution, while the smaller cubic boron nitride tailing particles will float on the upper surface of the hydrochloric acid or acidic solution, resulting in insufficient purification of the particles floating on the upper surface of the cubic boron nitride. At the same time, when taking out, the cubic boron nitride tailing particles adhere to the inner wall, making it indirectly inconvenient to take out. Summary of the Utility Model
[0006] In view of this, the utility model provides a device for extracting cubic boron nitride tailings, which can avoid the adhesion of cubic boron nitride tailing particles to the inner wall, and at the same time can immerse all the particles in the hydrochloric acid solution, improving the purity of the extracted tailing particles.
[0007] To solve the above technical problems, the present utility model provides a cubic boron nitride tailing extraction device, which includes an extraction box and a discharge box arranged on the upper surface of the extraction box. The interior of the discharge box is in communication with the interior of the extraction box. A water inlet pipe is arranged on the upper surface of the extraction box, and the water inlet pipe is fixedly installed on the extraction box. A water outlet pipe is arranged at the bottom of the extraction box, and the water outlet pipe is fixedly installed at the bottom of the extraction box. Its characteristics are as follows: A tailing placement cylinder is arranged in the discharge box. Multiple holes are arranged at the bottom of the tailing placement cylinder. Four lifting components are arranged at the top in the discharge box, and the four lifting components are fixedly installed on the discharge box. The ends of the four lifting components are connected to both sides of the tailing placement cylinder, and the ends of the lifting components are fixedly installed with the tailing placement cylinder. An inner wall cleaning component is arranged in the tailing placement cylinder. The inner wall cleaning component includes a cleaning circular block slidably arranged in the tailing placement cylinder. That is, the operator puts the tailings into the tailing placement cylinder, and then the lifting components descend, driving the tailing placement cylinder to descend accordingly. Then, acidic solution is added into the extraction box from the water inlet pipe, so that the tailings can be soaked, avoiding incomplete soaking of the tailings in the acidic solution and turning the tailings into hexagonal boron nitride. By controlling the lifting components again, the tailing placement cylinder can be lifted, and the liquid in the tailing placement cylinder flows into the extraction box along the multiple holes, so that the tailings adhere to the inside of the tailing placement cylinder. Then, driven by the inner wall cleaning component, the cleaning circular block pushes the tailings, avoiding the adhesion of the tailings inside the tailing placement cylinder and facilitating the discharge of the tailings inside the tailing placement cylinder.
[0008] The lifting components include four hydraulic telescopic rods arranged at the top of the discharge box. The hydraulic telescopic rods are fixedly installed at the top of the discharge box, and the ends of the four hydraulic telescopic rods are fixedly arranged on the upper surfaces of the fixing blocks on both sides of the tailing placement cylinder. That is, the use of the four hydraulic telescopic rods provides stability for the tailing placement cylinder.
[0009] The inner wall cleaning component includes a driving groove arranged at the top of the tailing placement cylinder. Guide grooves are arranged on both sides inside the tailing placement cylinder. A lead screw is arranged in the driving groove, and a guide post is arranged in the guide groove. The lead screw is threadedly arranged on the cleaning circular block, and the guide post penetrates through the inside of the cleaning circular block. That is, by rotating the lead screw, the cleaning circular block can be driven, indirectly enabling the cleaning circular block to prevent the tailings from adhering to the inner wall due to the remaining part of the solution.
[0010] The inner wall cleaning component includes a motor arranged at the end of the tailing placement cylinder. The motor is fixed to the side wall of the tailing placement cylinder by bolts, and the output shaft of the motor is fixedly arranged with the lead screw. That is, the motor provides driving force for the lead screw.
[0011] The inner wall cleaning component includes a protective housing arranged at the end of the tailing placement cylinder. The protective housing is located on the outer surface of the motor. That is, the protective housing can protect the motor.
[0012] The protective housing, guide groove, drive groove, lead screw, sliding column, tail material placement cylinder, cleaning round block, and hydraulic telescopic rod are all made of titanium alloy material; that is, titanium alloy material, which can reduce wear.
[0013] A sealing cover is hingedly arranged at the side end of the tail material placement cylinder through a hinge seat, and a sealing door is hingedly arranged at the side end of the discharge box through a hinge; that is, the sealing cover can prevent the tail material from spilling in the tail material placement cylinder, and at the same time, it is convenient for personnel to discharge the tail material. Then, the sealing door can prevent the internal and external air from entering the box body when extracting the tail material.
[0014] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:
[0015] 1. First, the personnel open the sealing door and the sealing cover, so that the tail material can be added into the tail material placement cylinder. Then, the sealing cover is closed again. Four hydraulic telescopic rods drive the tail material placement cylinder to descend. Then, acidic solution or alkaline solution is added from the water inlet pipe to indirectly fill the extraction tank with solution, so that the acidic solution enters multiple holes in the tail material placement cylinder, and the solution can evenly soak the tail material. Indirectly, the solution melts the impurities in the tail material. Then, the four hydraulic telescopic rods drive the tail material placement cylinder to rise, so that the liquid in the tail material placement cylinder flows out of the multiple holes and into the extraction tank. At this time, the tail material in the tail material placement cylinder is extracted as hexagonal boron nitride.
[0016] 2. Through the operation of the motor, the motor drives the lead screw to rotate, indirectly driving the cleaning round block to move, so that the tail material can be carried out, and the effect of cleaning the inner wall can be achieved indirectly. Brief Description of the Drawings

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will combine the accompanying drawings of the embodiments of the present utility model Figures 1-5 to clearly and completely describe the technical solutions of the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the present utility model.
[0027] Such as Figures 1-5As shown in the figure: This embodiment provides a cubic boron nitride tailing extraction device, including an extraction tank 100 and a discharge tank 101 arranged on the upper surface of the extraction tank 100. The inside of the discharge tank 101 is in communication with the inside of the extraction tank 100. A water inlet pipe 102 is arranged on the upper surface of the extraction tank 100. The water inlet pipe 102 is used to fill the inside of the extraction tank 100 with an acidic or alkaline solution, but does not spread to the connection between the discharge tank 101 and the extraction tank 100. A water outlet pipe 103 is arranged at the bottom of the extraction tank 100. After the new tailings are continuously in contact with hydrochloric acid or an acidic solution for a long time, the impurities in the tailings can be dissolved, and then relatively pure hexagonal boron nitride can be extracted. During the continuous purification process of the tailings, the performance of the acidic and alkaline solutions becomes too low and can be discharged from the water outlet pipe 103. It is characterized in that: a tailing placement cylinder 106 is arranged in the discharge tank 101. The placement cylinder is used to carry the tailings. Multiple holes 108 are arranged at the bottom of the tailing placement cylinder 106. The multiple holes 108 are in contact with the solution, so that the solution enters the inside of the tailing placement cylinder 106 and dissolves the impurities in the tailings, and indirectly the tailings can be purified. Four lifting components 200 are arranged at the top inside the discharge tank 101. The ends of the four lifting components 200 are connected to both sides of the tailing placement cylinder 106. The lifting components 200 can lower the tailing placement cylinder 106 so that the tailing placement cylinder 106 enters the extraction tank 100, and the solution soaks the upper surface of the tailing placement cylinder 106, so that the tailings can be completely soaked, and indirectly the tailings are soaked evenly. An inner wall cleaning component 300 is arranged inside the tailing placement cylinder 106. The inner wall cleaning component 300 includes a cleaning round block 307 slidably arranged inside the tailing placement cylinder 106. After the soaking is completed, because the tailings contain liquid and will stick to the inner wall, it is inconvenient for personnel to take out the tailings. By using the inner wall cleaning component 300, the cleaning round block 307 moves forward, so that the tailings sticking to the inner wall can be scraped, thus avoiding the sticking of the tailings and facilitating the taking out of the tailings;
[0028] First, the operator drives the cleaning circular block 307 in the inner wall cleaning component 300 to the side end of the tailing placing cylinder 106, so that the operator can add the tailings into the tailing placing cylinder 106. Then, through the operation of the lifting component 200, the tailing placing cylinder 106 is transferred from the discharge box 101 to the extraction box 100. Then, an acidic or alkaline solution is added into the water inlet pipe 102 on the upper surface of the extraction box 100 and fills the inside of the extraction box 100. Because there are multiple groups of holes 108 on the tailing placing cylinder 106, the acidic or alkaline solution enters the inside of the tailing placing cylinder 106, so that the acidic or alkaline solution can dissolve the impurities in the tailings, indirectly extract the tailings, and purify the tailings. Then, through the operation of the lifting component 200, the tailing placing cylinder 106 can be slowly lifted, and the acidic or alkaline solution is discharged into the extraction box 100 through the multiple groups of holes 108. When taking the material, the operator holds the collection box by hand and corresponds to the discharge port of the tailing placing cylinder 106. Then, through the use of the inner wall cleaning component 300, the cleaning circular block 307 is driven to slide inside the tailing placing cylinder 106, and at the same time, the tailings can be pushed, indirectly pushing the tailings into the collection box, and at the same time avoiding the purified tailings from sticking to the inner wall due to the presence of moisture.
[0029] The inner wall cleaning component 300 is as Figure 5 shown in Fig. 2
[0030] The lifting component 200 includes four hydraulic telescopic rods 202 arranged at the top of the discharge box 101. The four hydraulic telescopic rods 202 provide support for the placing cylinder. The ends of the four hydraulic telescopic rods 202 are fixedly arranged on the upper surfaces of the fixing blocks 201 on both sides of the tailing placing cylinder 106.
[0031] The inner wall cleaning component 300 includes a driving groove 304 arranged at the top of the tailing placing cylinder 106. Guide grooves 302 are arranged on both sides inside the tailing placing cylinder 106. A lead screw 303 is arranged in the driving groove 304. The lead screw 303 can rotate in the driving groove 304. A guide post is arranged in the guide groove 302. The guide post is fixedly arranged in the guide groove 302 by welding. The lead screw 303 is threadedly arranged with the cleaning circular block 307. The rotation of the lead screw 303 can drive the cleaning circular block 307 to move. The guide post passes through the inside of the cleaning circular block 307.
[0032] The inner wall cleaning component 300 includes a motor 305 arranged at the end of the tailing placing cylinder 106. The output shaft of the motor 305 is fixedly arranged with the lead screw 303.
[0033] The output shaft of the motor 305 drives the lead screw 303, causing the lead screw 303 to rotate. Since the external thread of the lead screw 303 meshes with the internal thread of the cleaning round block 307, the cleaning round block 307 can be driven to move. During the movement of the cleaning round block 307, the tail material can be carried out, indirectly achieving the effect of cleaning the inner wall.
[0034] Figure 3 The enlarged view at position A in Figure 4 is shown as
[0035] The inner wall cleaning assembly 300 includes a protective housing 306 provided at the end of the tail material placement cylinder 106. The protective housing 306 is fixed to the placement cylinder by bolts, and the protective housing 306 is located on the outer surface of the motor 305;
[0036] The protective housing 306 is as Figure 2 shown as
[0037] The protective housing 306, the guide groove 302, the drive groove 304, the lead screw 303, the sliding column 301, the tail material placement cylinder 106, the cleaning round block 307, and the hydraulic telescopic rod 202 are all made of titanium alloy material, which can prevent corrosion by acidic or alkaline solutions;
[0038] The tail material placement cylinder 106 is as Figure 1 shown as
[0039] A sealing cover 104 is hingedly provided at the side end of the tail material placement cylinder 106 through a hinge seat 107, which facilitates the removal of the tail material and can also prevent the leakage of the tail material. A sealing door 105 is hingedly provided at the side end of the discharge box 101 through a hinge, and the sealing door 105 can prevent air from entering the discharge box 101;
[0040] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0041] The above is the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
