Description

Technical Field

[0001] This utility model relates to the field of micro powder sorting technology, and more specifically, to a boron carbide micro powder sorting device. Background Technology

[0002] Boron carbide micro powder is widely used in many key fields such as ceramics, abrasives, and nuclear industry due to its high hardness, excellent wear resistance, and strong chemical stability. However, current boron carbide micro powder sorting methods have many problems. Traditional boron carbide micro powder sorting methods usually use gravity sedimentation, which is time-consuming and inefficient. Some vibrating screen sorting methods are ineffective for fine powders and cannot meet the required precision, resulting in uneven particle size and poor purity of the product, which cannot meet the stringent requirements of high-end industries. Therefore, new sorting technologies and equipment are urgently needed.

[0003] Therefore, a boron carbide micro powder sorting device is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a boron carbide micro powder sorting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a boron carbide micro powder sorting device, comprising a dynamic sedimentation trough, wherein two lifting frames are symmetrically fixedly arranged on the side wall of the dynamic sedimentation trough, and sliding grooves are fixedly connected to the two lifting frames via lifting components. Multiple connecting seats are slidably connected to the sliding grooves, and an isolation screening plate is fixedly connected to the bottom wall of each of the multiple connecting seats via a first connecting block. A connecting frame is fixedly connected to the surface of the isolation screening plate, and multiple locking grooves are formed on the upper surface of the connecting seats. Multiple U-shaped connecting rods are fixedly connected to the top of the sliding groove, and two reinforcing springs are symmetrically sleeved on the outer side of each U-shaped connecting rod. A connecting plate is slidably sleeved on the outer side of the multiple U-shaped connecting rods, and the bottom wall of the connecting plate is connected via a second connecting block. The connecting block is fixedly connected with locking teeth that engage with the locking groove. During use, the device can screen powders of different particle sizes by setting multiple isolation screening plates. The position of the isolation screening plates can be adjusted by sliding. The position of the multiple isolation screening plates can be moved and fixed after sliding based on the amount of powder accumulation on one side of the isolation screening plates with different filter holes. This structure can adjust the isolation screening plates in real time according to the amount of powder accumulation on one side of the isolation screening plates, thereby avoiding the blockage of the isolation screening plates of that particle size range due to excessive powder accumulation on one side, which would affect the filtration and the overall multi-segment particle size screening effect of the device.

[0006] Preferably, the lifting assembly includes a threaded rod, a lifting plate, and a lifting through hole. Each of the two lifting frames has a lifting through hole at its top. A threaded rod is rotatably connected to each of the two lifting frames. A lifting plate is threadedly connected to the outer side of each of the two threaded rods. The lifting plate movably passes through the lifting through hole at the top of the lifting frame. The tops of both lifting plates are fixedly connected to the side wall of the sliding groove. When removing the sieved powder from the dynamic sedimentation trough, a tool can be used to push the powder accumulated on the left side of each isolation screening plate onto the connecting frame. Then, by adjusting the rotating threaded rod, the lifting plate is driven to move upwards. The upward-moving lifting plate drives the sliding groove, multiple isolation screening plates slidably connected to the sliding groove, and the connecting frame to adjust their height. This adjustment of the connecting frame facilitates the upward movement of the powder accumulated on the connecting frame, allowing for quick and easy removal of the powder from the dynamic sedimentation trough for further processing, thus improving the practicality of the device.

[0007] Preferably, a sprocket is fixedly connected to the bottom end of each threaded rod, and a transmission chain is meshed with the outer sides of the two sprockets. A drive motor for driving the threaded rod is connected to the top end of one of the threaded rods, and the drive motor is fixed to the top of the lifting frame by bolts. When driving and adjusting the threaded rod, the threaded rod can be driven directly by the drive motor connected to the top end of one threaded rod. Then, the rotating threaded rod drives the sprocket connected to the bottom end to rotate. Subsequently, the synchronous rotation adjustment of the two threaded rods is achieved through the cooperation of the sprockets at the bottom ends of the two threaded rods and the transmission chain.

[0008] Preferably, a slurry mixing tank is provided on one side of the dynamic sedimentation trough, and the slurry mixing tank and the dynamic sedimentation trough are connected by a connecting pipe. The slurry that has been mixed in the slurry mixing tank can be transported to the dynamic sedimentation trough for segmented screening through the connecting pipe.

[0009] Preferably, a stirring shaft is rotatably connected inside the slurry mixing tank, and multiple stirring rods are fixedly connected to the outside of the stirring shaft. Two sets of connecting strips are symmetrically fixedly connected to the outside of the stirring shaft. A scraper is fixedly connected to the end of each set of connecting strips away from the stirring shaft. A drive motor is fixedly installed at the top of the stirring shaft to drive the stirring shaft. The drive motor drives the stirring shaft to drive the stirring rods to stir the slurry in the slurry mixing tank. At the same time as the stirring shaft rotates and is adjusted, the connecting strips drive the scraper to scrape off the slurry adhering to the inner wall of the slurry mixing tank.

[0010] Preferably, a regulating valve, an intelligent temperature-controlled heater, and an ultrasonic cavitation device are fixedly installed on the connecting pipe from left to right. The regulating valve, intelligent temperature-controlled heater, and ultrasonic cavitation device are all fixedly connected to the connecting pipe by flanges and bolts. During use, the slurry that is uniformly stirred in the slurry mixing tank has its flow rate precisely controlled by the regulating valve. Then, it flows through the connecting pipe to the location of the intelligent temperature-controlled heater. The intelligent temperature-controlled heater precisely controls the slurry temperature to reach the process temperature, laying a solid foundation for subsequent processes. Then, the heated slurry flows through the connecting pipe to the location of the ultrasonic cavitation device. After cavitation treatment by the ultrasonic cavitation device, the micro powder is fully dispersed. The treated slurry slowly flows into the dynamic sedimentation tank, and the flow rate of the slurry can be adjusted according to the settling velocity.

[0011] Preferably, a fine-particle recycling tank is connected to the other side of the dynamic sedimentation tank via a connecting pipe. A wastewater recovery tank is provided on one side of the fine-particle recycling tank. The fine-particle recycling tank and the wastewater recovery tank are connected and communicated via a conveying pipe, and a water pump is fixedly connected to the conveying pipe. The screened liquid flows into the fine-particle recycling tank for sedimentation treatment. Then, the settled fine particles can be collected in the fine-particle recovery tank. Finally, the wastewater is pumped into the wastewater recovery tank through the conveying pipe. The wastewater recovery tank is equipped with a wastewater filter element. The purified wastewater filtered by the wastewater filter element can realize the recycling of water resources.

[0012] The technical effects and advantages of this utility model are as follows: 1. Compared with the prior art, this boron carbide micro powder sorting device can sort micro powders of different particle sizes by setting multiple isolation screening plates. The multiple isolation screening plates are slidably connected to the sliding groove. The position of the multiple isolation screening plates can be slidably moved and fixed after sliding according to the amount of micro powder accumulated on one side of the isolation screening plates with different sizes of filter holes. This structure can adjust the isolation screening plates in real time according to the amount of micro powder accumulated on the side of the isolation screening plates, thereby avoiding the blockage of the multi-segment isolation screening plates due to excessive accumulation of micro powder on one side, which would affect the filtration use and also affect the overall multi-segment particle size sorting effect of the device.

[0013] 2. Compared with the prior art, this boron carbide micro powder sorting device uses a threaded rod to drive a lifting plate to move a sliding trough and multiple isolation screening plates and connecting frames that are slidably connected to the sliding trough for lifting and adjustment. Through the lifting and adjustment of the connecting frames, the micro powder accumulated on the connecting frames can be moved upwards, thereby facilitating the quick removal of the micro powder from the dynamic sedimentation trough for the next processing step, thus improving the practicality of the device.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] As attached Figures 1 to 5The boron carbide micro powder sorting device shown includes a dynamic sedimentation trough 1. Two lifting frames 13 are symmetrically fixedly installed on the side wall of the dynamic sedimentation trough 1. Sliding grooves 2 are fixedly connected to the two lifting frames 13 through lifting components. Multiple connecting seats 4 are slidably connected to the sliding grooves 2. An isolation screening plate 11 is fixedly connected to the bottom wall of each of the multiple connecting seats 4 through a first connecting block 3. A connecting frame 12 is fixedly connected to the surface of the isolation screening plate 11. Multiple locking grooves 5 are opened on the upper surface of the connecting seats 4. Multiple U-shaped connecting rods 6 are fixedly connected to the top of the sliding groove 2. Two strong springs 7 are symmetrically sleeved on the outside of each U-shaped connecting rod 6. A connecting plate 8 is slidably sleeved on the outside of the multiple U-shaped connecting rods 6. A locking tooth 10 that engages with the locking groove 5 is fixedly connected to the bottom wall of the connecting plate 8 through a second connecting block 9.

[0022] The device, when in use, can filter micro-powders of different particle sizes by setting multiple isolation screening plates 11. The position of the isolation screening plates 11 can be adjusted by sliding according to the amount of micro-powder accumulated on one side of the isolation screening plates 11 with different filter holes. Specifically, when too much micro-powder accumulates on one side of an isolation screening plate 11, causing blockage and affecting its ability to screen the slurry, the isolation screening plate 11 can be moved backward. This increases the storage space in that area, preventing excessive accumulation of micro-powder due to limited space, which could block the isolation screening plate 11. The position of the multiple isolation screening plates 11 can also be fixed after sliding. This structure allows for real-time adjustment of the isolation screening plates 11 based on the amount of micro-powder accumulated on each side, preventing blockage on one side of an isolation screening plate 11 due to excessive micro-powder accumulation, thus affecting its filtration performance and the overall multi-stage particle size screening effect of the device. Example

[0023] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details: In a preferred embodiment, the lifting assembly includes a threaded rod 14, a lifting plate 15, and a lifting through hole 16. Each of the two lifting frames 13 has a lifting through hole 16 at its top. A threaded rod 14 is rotatably connected to each of the two lifting frames 13. A lifting plate 15 is threadedly sleeved onto the outer side of each of the two threaded rods 14. The lifting plate 15 movably passes through the lifting through hole 16 at the top of the lifting frame 13. The tops of both lifting plates 15 are fixedly connected to the side wall of the sliding groove 2. A sprocket is fixedly connected to the bottom of each threaded rod 14. A transmission chain is meshed with the outer sides of both sprockets. A drive motor for driving the threaded rod 14 is connected to the top of one of the threaded rods 14, and the drive motor is fixedly mounted on the top of the lifting frame 13 by bolts. When removing the sieved micro-powder from the dynamic sedimentation wood tank 1, tools are used to separate each sieve. The fine powder accumulated on the left side of plate 11 is pushed onto the connecting frame 12. Then, a drive motor connected to the top of a threaded rod 14 drives the threaded rod 14. The rotating threaded rod 14 drives the sprocket connected to the bottom to rotate. Then, the sprockets at the bottom of the two threaded rods 14 and the transmission chain work together to achieve synchronous rotation adjustment of the two threaded rods 14. Then, by adjusting the rotating threaded rod 14, the lifting plate 15 is driven to move upward. The upward movement of the lifting plate 15 drives the sliding groove 2 and the multiple isolation screening plates 11 and the connecting frame 12 that are slidably connected to the sliding groove 2 to adjust their height. By adjusting the height of the connecting frame 12, the fine powder accumulated on the connecting frame 12 can be moved upward, so that the fine powder can be quickly removed from the dynamic sedimentation wooden tank 1 for the next processing step, thus improving the practicality of the device.

The slurry mixing tank 17 and the dynamic sedimentation wood tank 1 are connected by a connecting pipe 25. A stirring shaft 18 is rotatably connected inside the slurry mixing tank 17. Multiple stirring rods 19 are fixedly connected to the outside of the stirring shaft 18. Two sets of connecting strips 20 are symmetrically fixedly connected to the outside of the stirring shaft 18. A scraper 21 is fixedly connected to the end of each set of connecting strips 20 away from the stirring shaft 18. A drive motor for driving the stirring shaft 18 is fixedly installed at the top of the stirring shaft 18. A regulating valve 22, an intelligent temperature-controlled heater 23, and an ultrasonic cavitation device 24 are fixedly installed on the connecting pipe 25 from left to right. The regulating valve 22, the intelligent temperature-controlled heater 23, and the ultrasonic cavitation device 24 are all fixedly connected to the connecting pipe 25 by flanges and bolts. In use, firstly The stirring shaft 18 is driven by a drive motor to stir the stirring rod 19 in the slurry mixing tank 17. While the stirring shaft 18 is rotating and adjusting, the connecting strip 20 drives the scraper 21 to scrape off the slurry adhering to the inner wall of the slurry mixing tank 17. Then, the uniformly stirred slurry in the slurry mixing tank 17 is discharged through the regulating valve 22 with precise flow control. Subsequently, it flows through the connecting pipe 25 to the position of the intelligent temperature control heater 23. The intelligent temperature control heater 23 precisely controls the slurry temperature to reach the process temperature, laying a solid foundation for the subsequent process. Then, the heated slurry flows through the connecting pipe 25 to the position of the ultrasonic cavitation device 24. After cavitation treatment by the ultrasonic cavitation device 24, the micro powder is fully dispersed. The treated slurry slowly flows into the dynamic sedimentation wood tank 1, and the flow rate of the slurry can be adjusted according to the settling speed.

[0025] In a preferred embodiment, a fine particle recycling tank 26 is connected to the other side of the dynamic sedimentation tank 1 via a connecting pipe. A wastewater recovery tank 27 is provided on one side of the fine particle recycling tank 26. The fine particle recycling tank 26 and the wastewater recovery tank 27 are connected and communicated via a conveying pipe 28, and a water pump is fixedly connected to the conveying pipe 28. The screened liquid flows into the fine particle recycling tank 26 for sedimentation treatment. Then, the settled fine particles can be collected in the fine particle recovery tank 26. Finally, the wastewater is drawn into the wastewater recovery tank 27 through the conveying pipe 28. A wastewater filter element is provided in the wastewater recovery tank 27. The purified wastewater filtered by the wastewater filter element can realize the recycling of water resources.

[0026] In this embodiment, the drive motor regulating valve 22, intelligent temperature control heater 23, ultrasonic cavitation device 24 and water pump are all commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here we are only using them without making any structural or functional improvements, and we will not go into detail here.

[0027] The working process of this utility model is as follows: First, by setting multiple isolation screening plates 11, micro powder of different particle size ranges can be screened. The position of the isolation screening plate 11 can be adjusted by sliding according to the amount of micro powder accumulation on one side of the isolation screening plate 11 with different filter holes. That is, when the amount of micro powder accumulated on one side of a certain isolation screening plate 11 is too much and has formed a certain blockage on the surface of the isolation screening plate 11, affecting the screening of the slurry by the isolation screening plate 11, the position of the isolation screening plate 11 can be moved backward, thereby ensuring that the storage space in this area is increased, and avoiding the accumulation of micro powder trapped by screening due to the small space, which would block the isolation screening plate 11. Meanwhile, after the position of the isolation screening plate 11 is adjusted, when fixing the position of the isolation screening plate 11, the connecting plate 8 is squeezed by the strong spring 7. The squeezed connecting plate 8 drives the locking tooth 10 to engage with the locking groove 5 opened on the upper surface of the connecting seat 4 through the second connecting block 9, thereby locking the position of the connecting seat 4 and the isolation screening plate 11 after the position is adjusted. This structure can adjust the isolation screening plate 11 in real time according to the amount of fine powder accumulated on one side of the isolation screening plate 11, thereby avoiding the blockage of the isolation screening plate 11 on one side of the isolation screening plate 11 due to excessive fine powder accumulation, which would affect its filtration use. Finally, when removing the micro powder that has been screened in the dynamic sedimentation trough 1, the micro powder accumulated on the left side of each isolation screening plate 11 can be pushed onto the connecting frame 12 using a tool. Then, by adjusting the rotating threaded rod 14, the lifting plate 15 is driven to move upward. The upward movement of the lifting plate 15 drives the sliding trough 2 and the multiple isolation screening plates 11 and connecting frame 12 that are slidably connected to the sliding trough 2 to adjust their height. By adjusting the height of the connecting frame 12, it is convenient to move the micro powder accumulated on the connecting frame 12 upward, thereby facilitating the quick removal of the micro powder from the dynamic sedimentation trough 1 for the next processing step, improving the practicality of the device, and also affecting the overall multi-stage particle size screening effect of the device. The above is the working principle of the boron carbide micro powder sorting device.
