Description

Technical Field

[0001] The utility model relates to the technical field of microsphere screening, in particular to a microsphere screening device. Background Technique

[0002] At present, the most commonly used screening method is to screen through a vibrating screen. However, for microspheres with small particle sizes, the accuracy of the vibrating screen is insufficient, and it is impossible to finely screen the microspheres well. In addition, due to the action of surface tension, the efficiency of using a vibrating screen to screen liquids is also not high. For the screening of microspheres in liquids, methods such as centrifugation and filtration are usually used, but there are problems such as low efficiency, long time consumption, and complex operation. When the centrifugation method is actually used, the capacity is too small and the operation is troublesome, making it difficult to meet the needs of experiments and production. When using the filtration method, due to the bridging phenomenon of microspheres, the efficiency and accuracy will decrease after filtering for a period of time;

[0003] Some devices will adopt the method of vibration plus suction filtration to screen microspheres. By vibrating, the microspheres are dispersed in the liquid phase, and the microspheres are filtered out when the liquid phase passes through the cross-shaped filter screen. This method can effectively avoid the bridging phenomenon of microsphere filtration. However, as the content of microspheres in the filtration chamber gradually increases, even if the microspheres are dispersed in the liquid phase, the liquid phase permeability of the filter screen will become worse due to the too high content of microspheres, resulting in a decrease in the suction filtration efficiency.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a microsphere screening device, including a support 1, a water pump 2, and a screening box 4. The screening box 4 is installed on the top of the support 1, and a screening mechanism 5 is arranged inside the screening box 4;

[0021] The screening mechanism 5 includes a hollow tube 501. The hollow tube 501 passes through the right outer wall of the screening box 4 through bearings. A connecting pipe 504 is connected to the left end of the hollow tube 501. A Y-shaped plate 505 is fixedly installed at the left end of the connecting pipe 504. The central axis of the Y-shaped plate 505 coincides with the central axis of the hollow tube 501. A driving component 503 is connected to the outer wall of the hollow tube 501 in a driving manner. A rotary joint 502 is connected to the right end of the hollow tube 501. The rotary joint 502 is connected to the water inlet end of the water pump 2 through a pipeline. A filter cylinder 506 is fixedly installed on the left outer wall of the Y-shaped plate 505. The inside of the filter cylinder 506 is communicated with the inside of the connecting pipe 504. A cross-shaped filter screen 507 is installed on the left outer wall of the Y-shaped plate 505 through a quick-release component 508. There are two filter cylinders 506. The cross-shaped filter screen 507 and the two filter cylinders 506 are respectively located at the three ends of the Y-shaped plate 505. The liquid phase in the screening box 4 is pumped into the filter cylinder 506 by the water pump 2. The fine particles in the liquid phase are filtered out by the filter cylinder 506 to achieve suction filtration. The driving component 503 is used to drive the hollow tube 501 to rotate, and then drive the connecting pipe 504 to rotate. The rotation of the connecting pipe 504 drives the Y-shaped plate 505 to rotate, and then drives the two filter cylinders 506 to rotate, so that the filter cylinder 506 can contact the liquid phase at different positions, achieving the purpose of filtering while stirring. The liquid phase impacts the filter cylinder 506 to prevent a large amount of fine particles from adsorbing on the filter cylinder 506. After the content of fine particles in the screening box 4 is too high, by reducing the rotation speed of the hollow tube 501, the cross-shaped filter screen 507 can adsorb the fine particles in the screening box 4 together. After the cross-shaped filter screen 507 is rotated out of the screening box 4, stop the driving component 503 and replace the cross-shaped filter screen 507, and a large amount of fine particles adsorbed on the cross-shaped filter screen 507 can be taken away, thereby greatly reducing the content of fine particles in the screening box 4. At the same time, the filter cylinder 506 can still perform suction filtration to ensure the suction filtration efficiency. The cross-shaped filter screen 507 is beneficial for the adsorption of fine particles. The rotary joint 502 is provided so that the hollow tube 501 can still be connected to the water inlet end of the water pump 2 when it rotates;

[0022] The driving component 503 includes a motor 5031. The motor 5031 is fixedly installed on the back surface of the screening box 4. The output end of the motor 5031 is fixedly installed with a rotating shaft 5032. The rotating shaft 5032 is connected to the hollow tube 501 in a driving manner through a pulley group. The motor 5031 drives the rotating shaft 5032 to rotate, and then drives the hollow tube 501 to rotate;

[0023] The quick-release component 508 includes a card slot 5081 and a plug rod 5082. The card slot 5081 is formed on the outer wall of the Y-shaped plate 505. The plug rod 5082 is fixedly installed on the right end of the cross-shaped filter net 507. The plug rod 5082 passes through the card slot 5081. An elastic pad 5083 is slidably sleeved on the outer wall of the plug rod 5082. A nut 5084 is threadedly sleeved on the outer wall of the plug rod 5082. By inserting the plug rod 5082 into the card slot 5081 and then using the nut 5084 for fastening, quick installation can be achieved. When disassembling, just unscrew the nut 5084 and then take out the plug rod 5082 from the card slot 5081, and the cross-shaped filter net 507 can be replaced. Then collect the fine particles adsorbed on the cross-shaped filter net 507. The elastic pad 5083 is provided to ensure the fastening effect of the nut 5084 on the plug rod 5082 and prevent the nut 5084 from loosening due to vibration;

[0024] A lid 10 is rotatably provided at the top of the screening box 4. The lid 10 is an arc-shaped lid. A water inlet pipe 11 is communicated at the top of the lid 10. The water inlet pipe 11 is provided for adding unscreened liquid phase into the screening box 4;

[0025] The water outlet end of the water pump 2 is communicated with a liquid leakage box 3 through a pipeline. A drain pipe 9 is communicated on the right side of the liquid leakage box 3. A valve is provided on the drain pipe 9. The liquid leakage box 3 is provided for recycling the filtered liquid phase;

[0026] An ultrasonic device 8 is fixedly installed on the left outer wall of the bracket 1. The ultrasonic device 8 is electrically connected with an ultrasonic probe 6 through a wire harness. The ultrasonic probe 6 is inserted into the screening box 4, and a sealing ring 7 is provided at the part where the ultrasonic probe 6 is inserted into the screening box 4. The ultrasonic device 8 is used to control the ultrasonic probe 6 to work. The ultrasonic probe 6 generates ultrasonic waves to produce a strong oscillation in the screening box 4, which not only reduces the mutual aggregation of microspheres in the liquid but also effectively alleviates the adsorption of microspheres on the filter cylinder 506.

[0027] Working principle: When in use, the un-screened liquid phase is introduced into the screening box 4 through the water inlet pipe 11, and then the water pump 2 is turned on to pump the liquid phase from the screening box 4 into the filter cylinder 506, and then it flows through the connecting pipe 504, the hollow pipe 501, and the water pump 2 in sequence and enters the liquid leakage box 3. When the liquid phase passes through the filter cylinder 506, the qualified fine particles in it are filtered out. By turning on the motor 5031 to drive the rotating shaft 5032 to rotate, and then driving the hollow pipe 501 to rotate. The rotation of the hollow pipe 501 drives the Y-shaped plate 505 to rotate through the connecting pipe 504, and then drives the filter cylinder 506 and the cross-shaped filter screen 507 to rotate, so that the filter cylinder 506 contacts the liquid phase at different positions, filters the liquid phase at different positions, and can also stir the liquid phase to disperse the fine particles and improve the filtering effect. When the fine particle content in the screening box 4 is too high, open the box cover 10, and then reduce the rotation speed of the motor 5031, thereby reducing the rotation speed of the hollow pipe 501, so that the fine particles can be adsorbed on the cross-shaped filter screen 507 after contacting the cross-shaped filter screen 507. After the cross-shaped filter screen 507 rotates out of the screening box 4, unscrew the nut 5084, and then replace the cross-shaped filter screen 507, and a large number of fine particles can be taken out of the screening box 4 to reduce the fine particle content in the screening box 4. Then increase the rotation speed of the motor 5031 to carry out normal suction filtration.

[0028] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
