Technical Field
[0001] This utility model belongs to the technical field of liquid separation equipment, specifically relating to a liquid separation device for washing green silicon carbide micro powder. Background Technology
[0002] Green silicon carbide is made from petroleum coke and high-quality silica as the main raw materials, with salt added as an additive, and is smelted at high temperature in an electric resistance furnace. The resulting crystals have high purity and high hardness, with a hardness between corundum and diamond, and mechanical strength higher than corundum. During the water washing process of green silicon carbide micro powder, separation equipment is usually used for liquid separation.
[0003] Currently, most existing liquid separation equipment for green silicon carbide micro powder uses traditional centrifuges for liquid separation. However, it is difficult to completely retain fine particles, resulting in some fine powder remaining in the centrifuged liquid. This is not conducive to ensuring the full utilization of green silicon carbide micro powder, lacks the function of filtering and separating it, and is prone to clogging, which cannot guarantee separation efficiency and effect, causing great inconvenience to users.

[0008] In a preferred embodiment, the drive assembly includes a dual-axis motor, which is fixedly mounted on the top of the housing. A first drive gear and a second drive gear are fixedly mounted on the two output shafts of the dual-axis motor, respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This liquid separation equipment for washing green silicon carbide micro powder, by setting up a drive component, a separation component, and a spiral component, utilizes a dual-shaft motor to drive the first and second drive gears to rotate, which in turn drive the first and second driven gears to rotate, thereby achieving the purpose of driving the rotating drum and the spiral feeder to rotate respectively. This causes the green silicon carbide micro powder slurry to rotate at high speed, and the liquid phase and solid phase in the green silicon carbide micro powder slurry are initially concentrated and separated by centrifugal force and density difference. By utilizing the speed difference between the two, the spiral feeder rotates to achieve the purpose of continuous slag discharge, thereby improving the washing efficiency and effect. This liquid separation equipment for washing green silicon carbide micro powder uses a filter assembly and a third driven gear to drive the liquid guide shaft to rotate, thereby rotating the filter plate and achieving the purpose of filtering the liquid after the initial separation. This achieves the effect of intercepting and filtering the fine powder again, improving the product recovery rate. At the same time, by setting a scraper to contact and scrape the filter plate, the filter plate is prevented from clogging, improving the filtration effect and ensuring the solid-liquid separation effect of the green silicon carbide micro powder in the second filtration.

[0015] The present invention will be further described below with reference to the embodiments.
[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.
[0017] Please see Figure 1 and Figure 2This utility model provides a liquid separation device for washing green silicon carbide micro powder, including a shell 1 and a tank 6. A sealed inspection door 2 is fixedly installed on the front side of the shell 1 by bolts. A separation component 9 is installed inside the shell 1. The separation component 9 includes a first bearing 91, which is installed on the left and right sides of the shell 1. A rotating drum 94 is rotatably connected inside the first bearing 91. A slider 92 is fixedly connected to the surface of the rotating drum 94. A slide rail 96 is correspondingly opened on the surface of the inner wall of the shell 1. The slider 92 is slidably connected in the slide rail 96. A feed pipe 12 is passed through one end of the rotating drum 94 and is fixedly connected to an external conveying device. A liquid discharge port 93 and a slag discharge port 95 are opened on the surface of the rotating drum 94. In this embodiment, the rotating drum 94 rotates the green silicon carbide micro powder slurry conveyed inside at high speed to form a strong centrifugal force, which separates the liquid phase and solid phase in the green silicon carbide micro powder slurry, achieving a preliminary solid-liquid separation effect.
[0018] Please see Figure 2 The separation assembly 9 is equipped with a spiral assembly 10, which includes a second bearing 102. The second bearing 102 is installed at one end of the drum 94. A hollow shaft 101 is rotatably connected inside the second bearing 102. A spiral feeder 103 is fixedly connected to the surface of the hollow shaft 101. A rotary joint 105 is fixedly installed at one end of the spiral feeder 103. The other end of the rotary joint 105 is fixedly installed on the feed pipe 12. A discharge port 104 is opened on the surface of the spiral feeder 103. In this embodiment, the green silicon carbide micro powder slurry is transported into the screw feeder 103 by rotating the screw feeder 103 and connecting to the external conveying equipment through the feed pipe 12. The green silicon carbide micro powder slurry is then transported into the rotating drum 94 through the discharge port 104. The rotation of the screw feeder 103 also serves to push the separated solid sludge, thereby improving the solid-liquid separation efficiency.
[0019] Please see Figure 1 A drive assembly 5 is installed on the top of the housing 1. The drive assembly 5 includes a dual-axis motor 53. The dual-axis motor 53 is fixedly installed on the top of the housing 1. A first drive gear 52 and a second drive gear 54 are fixedly installed on the two output shafts of the dual-axis motor 53, respectively. A first driven gear 51 and a second driven gear 55 are meshed and connected to the bottom of the first drive gear 52 and the second drive gear 54, respectively. The first driven gear 51 and the second driven gear 55 are fixedly installed on one end of the hollow rotating shaft 101 and one end of the rotating drum 94, respectively. A third driven gear 56 is meshed and connected to the bottom of the first driven gear 51. In this embodiment, the dual-axis motor 53 operates to drive the first driving gear 52 and the first driven gear 51 to mesh and rotate, thereby driving the screw feeder 103 to rotate. It also drives the second driving gear 54 and the second driven gear 55 to mesh and rotate, thereby driving the drum 94 to rotate. At the same time, the meshing and rotation of the first driven gear 51 and the third driven gear 56 drives the guide shaft 112 to rotate.
[0020] Please see Figure 1 , Figure 3 and Figure 4 The tank body 6 is equipped with a filter assembly 11. The filter assembly 11 includes two third bearings 111. The third bearings 111 are installed at the top and bottom of the tank body 6. A liquid guide shaft 112 is rotatably connected inside the third bearings 111. Multiple filter plates 114 are fixedly connected to the surface of the liquid guide shaft 112. Multiple scrapers 113 are fixedly installed on the inner wall of the tank body 6. The bottom of the scraper 113 overlaps with the top of the filter plate 114. A spiral pusher 115 is fixedly connected to the bottom surface of the liquid guide shaft 112. A third driven gear 56 is fixedly connected to the top of the liquid guide shaft 112. A liquid guide port 116 is opened on the surface of the liquid guide shaft 112 corresponding to the bottom of the filter plate 114. The bottom end of the liquid guide shaft 112 is fixedly connected to the top of the second drain valve 8. The filter plate 114 is made of rigid porous sintered metal filter plate. In this embodiment, the rotation of the liquid guide shaft 112 can drive the rotation of multiple filter plates 114. After the liquid is filtered through the filter plates 114, it enters the liquid guide shaft 112 through the liquid guide port 116 and is discharged through the second liquid guide valve. Under the action of the scraper 113, the filter cake formed by the throttling solid particles is scraped off by the rotation of the filter plates 114 and pushed to the bottom by the action of the screw pusher 115. The discharge effect is achieved by the second slag discharge valve 7, thus achieving the purpose of secondary solid-liquid separation.
[0021] Please see Figure 1 The bottom of the shell 1 is fixedly connected to a first drain valve 4 and a first slag valve 3. The drain port 93 and the slag port 95 correspond to the first drain valve 4 and the first slag valve 3. One end of the first drain valve 4 is fixedly connected to the side of the tank body 6. The bottom of the tank body 6 is fixedly installed with a second slag valve 7 and a second drain valve 8.
[0022] In this embodiment, the high-concentration underflow and centrifugal liquid can be discharged through the first drain valve 4 and the first slag discharge valve 3 via the drain port 93 and the slag discharge port 95. The first drain valve 4 is connected to the tank 6 to guide the high-concentration underflow. The filter cake after the initial concentration and separation is discharged and collected through the first slag discharge valve 3. The clear liquid and the low-moisture filter cake after filtration and separation are discharged separately through the second drain valve 8 and the second slag discharge valve 7.
[0023] The working principle and usage process of this utility model are as follows: First, connect the feed pipe 12 to the external conveying equipment, then convey the green silicon carbide micro powder slurry to the screw feeder 103 through the feed pipe 12 and the rotary joint 105, and convey the green silicon carbide micro powder slurry to the rotary drum 94 through the discharge port 104. By controlling the operation of the dual-shaft motor 53, the second drive gear 54 and the second driven gear 55 are driven to mesh and rotate, which in turn drives the drum 94 to rotate. This causes the green silicon carbide micro powder slurry to rotate at high speed, generating a strong centrifugal force. Under the action of centrifugal force, the denser solid particles are thrown towards the inner wall of the drum 94 and deposited to form a sediment layer. The less dense water separates from the sediment layer. At the same time, the first drive gear 52 and the first driven gear 51 mesh and rotate. The difference in the number of teeth between the first drive gear 52 and the second drive gear 54 creates a speed difference, causing the first driven gear 51 to drive the screw feeder 103 to rotate at a slower speed than the drum 94. This pushes the sediment layer and allows for continuous slag discharge through the slag discharge port 95 and the first slag discharge valve 3. The green silicon carbide micro powder filter cake formed after preliminary concentration and separation is collected. The separated liquid enters the tank 6 through the drain port 93 and the first drain valve 4. Simultaneously, the rotation of the first driven gear 51 drives the rotation of the third driven gear 56, which in turn drives the filter plate 114 to rotate, thus filtering the liquid again. The clear liquid enters the liquid guide port 116 opened at the bottom of the filter plate 114 and is discharged through the second drain valve 8 at the bottom. At the same time, the intercepted solid particles form a filter cake on the surface of the aluminum plate. Under the action of the scraper 113 and the centrifugal force of the rotation of the filter plate 114, the filter cake is not blocked, but is thrown to the bottom of the tank 6 through the gap formed between the filter plate 114 and the inner wall of the tank 6. It is then pushed downward by the rotation of the spiral pusher 115 and discharged through the second slag discharge valve 7. The filter cake after secondary filtration and separation is collected to achieve secondary solid-liquid separation.
