Description

Technical Field

[0001] The invention relates to the technical field of silicon carbide grouting, in particular to a silicon carbide grouting stirring device. Background Art

[0002] Silicon carbide is an inorganic non-metallic material with extremely high hardness. It is synthesized by mixing sand and graphite under high temperature conditions. Silicon carbide grouting is a process in which silicon carbide particles are mixed with a binder and then injected into a mold or gap to form a complex-shaped silicon carbide product after curing. Because the uniformity and fluidity of the mixture in the silicon carbide slurry need to be ensured before grouting to ensure the quality and performance of the final product, stirring operations are usually required to ensure that the silicon carbide powder and the binder are fully mixed, thereby preparing high-quality silicon carbide composite materials.

[0003] At present, there are the following disadvantages when stirring silicon carbide: 1. When stirring silicon carbide slurry, silicon carbide powder must be introduced into the stirring tank first, and then liquid binder is introduced from the top of the stirring tank, and then the central shaft is rotated to rotate with the central paddle to stir the silicon carbide slurry. In the above operation, the stirring is mainly concentrated in the central part of the stirring tank, while the stirring force in the side wall area of ​​the stirring tank is insufficient, which can easily lead to uneven distribution of silicon carbide particles and binder, affecting the consistency and quality of the final product, and silicon carbide particles in the insufficiently stirred area are prone to agglomeration, affecting the mechanical strength and durability of the product; 2. When the liquid binder is introduced into the silicon carbide powder, it is usually injected from top to bottom, which will cause the silicon carbide powder that contacts first to mix with a large amount of binder to form a locally high-concentration slurry, and this uneven concentration distribution will affect the subsequent mixing effect and the performance of the final product; 3. After the stirring is completed, because the silicon carbide slurry has a certain viscosity, it is easy to cause part of the slurry to adhere to the side wall of the tank, which is not easy to clean and will affect the stirring efficiency.

[0033] See also Figure 1 , Figure 2 and Figure 3 The driving part 41 includes a central shaft 411 which is installed at the center of the lower end surface of the sealing cover 3 through a bearing and is located in the stirring tank 2. The upper end surface of the sealing cover 3 is fixedly installed with a motor 412 whose output end is fixedly connected to the upper end of the central shaft 411 through a motor seat.

[0034] See also Figure 3 and Figure 4 The stirring portion 42 includes a propeller blade 421 fixedly mounted on the outer ring wall of the central shaft 411 and located between the upper and lower tripods 7 , and a plurality of stirring blades 422 evenly distributed along the contour of the propeller blade 421 are fixedly mounted on the propeller blade 421 .

[0035] See also Figure 1 , Figure 2 and Figure 3 The grouting part 61 includes an upper ring pipe 611 fixedly installed on the upper end of the outer ring wall of the stirring tank 2, a plurality of upper through pipes 612 connected to the upper ring pipe 611 are evenly distributed along the circumference of the upper end of the inner ring wall of the stirring tank 2, a lower ring pipe 613 is fixedly installed on the lower end of the outer ring wall of the stirring tank 2, a plurality of lower through pipes 614 connected to the lower ring pipe 613 are evenly distributed along the circumference of the lower end of the inner ring wall of the stirring tank 2, a one-way valve (not shown in the figure) is fixedly installed in the lower through pipe 614, and the upper ring pipe 611 is connected to the lower ring pipe 613 through a T-shaped connecting pipe.

[0036] During specific operation, silicon carbide is first introduced into the stirring tank 2, and then the external liquid pump is started to inject the liquid binder into the upper ring pipe 611 and the lower ring pipe 613 through the T-shaped connecting pipe, so that the liquid binder enters the stirring tank 2 through the upper pipe 612 and the lower pipe 614 respectively, and the one-way valve in the lower pipe 614 ensures that the slurry in the stirring tank 2 will not flow out of the lower pipe 614, so that the binder is injected into the silicon carbide slurry synchronously from top to bottom, thereby promoting material exchange and mixing between the upper and lower layers, and improving the overall uniformity of the slurry.

[0037] Then, the motor 412 is started to rotate the central shaft 411 , so that the central shaft 411 brings the propeller blades 421 and the stirring blades 422 to stir and mix the silicon carbide slurry in the center of the stirring tank 2 .

[0038] See also Figure 3 and Figure 4 The support part 51 includes an annular slide rail 511 fixedly installed on the upper end of the inner ring wall of the stirring tank 2. The annular slide rail 511 is located below the upper through pipe 612. Three supporting sliders 512 evenly distributed along its circumference are slidably installed in the annular slide rail 511. An electric guide rail 513 is fixedly installed on the lower end of the supporting slider 512. A positioning column 514 is fixedly installed on the side of the upper end surface of the electric guide rail 513 away from the corresponding supporting slider 512.

[0039] See also Figure 3 , Figure 4 and Figure 5 The sliding part 52 includes a limit plate 521 fixedly mounted on the electric guide rail 513 and symmetrical about the center of the corresponding electric guide rail 513. A side wall of the limit plate 521 away from the central shaft 411 is provided with a plurality of material passing grooves 522 in a linear array from top to bottom. A side wall of two limit plates 521 on the same electric guide rail 513 close to each other is uniformly provided with a plurality of limit sliding grooves 523 from top to bottom. A positioning block is fixedly mounted on the lower ends of the two limit plates 521 on the same electric guide rail 513.

[0040] See also Figure 3 , Figure 5 and Figure 6 The switching part 53 includes a slide plate 531 fixedly installed at the moving end of the electric guide rail 513 and located between the corresponding two limit plates 521. A side wall of the slide plate 531 close to the central shaft 411 is provided with a matching groove 532 staggered up and down with the material passing groove 522. A limit sliding block 533 slidingly connected to the corresponding limit sliding groove 523 is fixedly installed on the slide plate 531. A scraper plate 534 is fixedly installed on the side wall of the slide plate 531 away from the central shaft 411.

[0041] See also Figure 3 , Figure 5 and Figure 6The actuator 54 includes a plurality of support rods 541 fixedly mounted on a side wall of the slide 531 close to the central axis 411 in a linear array from top to bottom, and a side paddle 542 is fixedly mounted on one end of the support rod 541 away from the corresponding slide 531.

[0042] See also Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The electric guide rail 513 is not on any radial extension line of the stirring tank 2. A connecting ring 71 distributed up and down is fixedly sleeved on the outer ring wall of the central shaft 411. The connecting ring 71 corresponds to the tripod 7 one by one. The connecting ring 71 is fixedly connected to the corresponding tripod 7 through a connecting rod 72 arranged on the diagonal line of the tripod 7. The upper ends of the three positioning columns 514 all pass through the angle of the upper tripod 7 and are fixedly connected to the tripod 7. The lower end surfaces of the three positioning blocks are fixedly connected to the lower tripod 7.

[0043] During specific operation, when the stirring mechanism 4 stirs the silicon carbide slurry in the center, the central shaft 411 drives the tripod 7 to rotate through the connecting ring 71 and the connecting rod 72, thereby synchronously rotating the three supporting sliders 512 in the ring slide rail 511 through the tripod 7. At this time, the slide plate 531 is located on the side of the electric guide rail 513 close to the central shaft 411, and the matching groove 532 on the slide plate 531 and the corresponding material passing groove 522 are in a state of back-to-back, and the supporting slider 512 will drive the corresponding slide plate 531 and the limit plate 521 to follow the central shaft 411 and rotate with the central shaft 411 as the axis, and at this time, the slide plate 531 and the side paddle 542 will stir the silicon carbide slurry located at the side wall of the stirring tank 2, and cooperate with the propeller blade 421 and the stirring paddle 422 to stir and mix the silicon carbide slurry in the center of the stirring tank 2, so as to achieve synchronous stirring of the inside and outside of the silicon carbide slurry, ensure that the slurry is fully mixed in the entire stirring tank 2, and improve the performance consistency of the final product.

[0044] It should be noted that during the process of the slide plate 531 and the limit plate 521 rotating and stirring the silicon carbide slurry, the corresponding material passing grooves 522 and the matching grooves 532 will reduce the direct impact area of ​​the silicon carbide slurry on the slide plate 531 and the limit plate 521. At the same time, due to the setting of the material passing grooves 522 and the matching grooves 532, the corresponding raised parts of the slide plate 531 and the limit plate 521 also have a stirring effect, stirring the silicon carbide slurry during the rotation process.

[0045] Furthermore, during the stirring process, since the electric guide rail 513 is not on any radial extension line of the stirring tank 2, the electric guide rail 513 with the slide plate 531, the limit plate 521 and the side paddle 542 are all in an offset state. Therefore, when the silicon carbide slurry at the side wall of the stirring tank 2 is stirred, it will not directly bear the pressure of the silicon carbide slurry, thereby extending the service life of the equipment. In addition, a certain axial flow will be generated during the stirring process, which will promote the circulation and exchange of the upper and lower layers of slurry, help to break the laminar flow state in the slurry, improve the mixing effect, and obtain a more uniform silicon carbide slurry.

[0046] At the same time, while the central shaft 411 is stirring the silicon carbide slurry with the actuator 5 and the stirring mechanism 4, the upper and lower tripods 7 and the actuator 5 form a triangular prism-type stable support, thereby reducing the deformation and displacement of the equipment under high load conditions during the stirring process, and can effectively offset the vibration and unbalanced force generated during the stirring process.

[0047] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 The slurry discharge part 62 includes an L-shaped discharge pipe 621 fixedly installed at the center of the lower end surface of the stirring tank 2 and connected with the stirring tank 2. A one-way valve (not shown in the figure) is provided in the L-shaped discharge pipe 621. A suction pump 622 whose suction end is fixedly connected to the discharge end of the L-shaped discharge pipe 621 is fixedly installed on the upper end surface of the base 1. A slurry discharge pipe 623 is fixedly installed at the discharge end of the suction pump 622. A connecting valve 624 is provided on the slurry discharge pipe 623.

[0048] During specific operation, after the stirring of the silicon carbide slurry is completed, the suction pump 622 is started and the connecting valve 624 and the one-way valve in the L-shaped discharge pipe 621 are opened, so that the suction pump 622 extracts and discharges the silicon carbide slurry from the stirring tank 2 through the L-shaped discharge pipe 621.

[0049] At the same time, the electric guide rail 513 is started to make its moving end move with the slide plate 531 toward the side wall of the mixing tank 2. During this process, the two limit plates 521 on the same electric guide rail 513 gradually cover the corresponding matching grooves 532, and the slide plate 531 gradually covers the material passing grooves 522 on the corresponding limit plates 521. Finally, the slide plate 531 and the scraper plate 534 fit the inner ring wall of the mixing tank 2. At this time, the two limit plates 521 and the slide plate 531 form a complete scraper vertical plate, and the two limit plates 521 stably support the corresponding slide plate 531. Subsequently, the stirring mechanism 4 drives the actuator 5 to rotate, so that the slurry attached to the inner wall of the mixing tank 2 can be scraped off, thereby reducing the problem of silicon carbide slurry sticking to the wall and improving the utilization rate of the material.
