Description

Technical Field

[0001] The present invention relates to the field of mixing technology, in particular to a mixing device for producing blood purification adsorbent. Background Art

[0002] Blood purification adsorbents are core materials in blood purification technology. They remove pathogenic substances from the blood through physical or chemical reactions and play a key role in clinical treatment. During the coating process of blood purification adsorbents, the following situations may occur: 1. During coating, the activated carbon floats on the liquid surface, and existing mixing equipment makes it difficult to mix the coating liquid and activated carbon from the liquid surface. This affects its coating efficiency. 2. During the coating process, some of the activated carbon enters the coating liquid through its pores and will gradually sink to the bottom of the liquid. At this time, the density of the activated carbon at the bottom is higher, and it is more likely to come into contact with each other, resulting in poor coating effect.

[0003] The Chinese patent with announcement number CN119701759B discloses a quantitative mixing device for raw materials for refractory brick processing, including a mixing tank and a mixing mechanism arranged in the mixing tank for stirring the refractory brick raw materials. The top of the mixing tank is fixedly connected to a discharge frame, and the top of the discharge frame is fixedly connected to a quantitative cylinder. The discharge frame is provided with a discharge mechanism for quantitatively discharging the raw materials in the quantitative cylinder. The center position of the quantitative cylinder is fixedly connected to an upper cylinder, and four partitions are fixedly connected at equal distances between the inner side of the quantitative cylinder and the upper cylinder. The bottom end of the quantitative cylinder is provided with an arc-shaped discharge port between the four partitions, and the side walls of the four partitions are provided with an adjustment plate. The inner side of the upper cylinder is rotatably connected to four lower cylinders.

[0004] When mixing the refractory brick raw materials, the above technical solution first places the refractory brick raw materials between the partitions in the metering cylinder respectively, and then during mixing, controls the discharge mechanism to start and release the blockage at the arc-shaped discharge port, and discharges the raw materials in the metering cylinder into the mixing tank in a quantitative manner. After the quantitative discharge, the discharge mechanism is closed and the mixing mechanism is controlled to start again to mix the raw materials in the mixing tank. After the mixing is completed, the discharge port at the bottom of the mixing tank is opened to discharge the mixed raw materials. However, since the adsorbent will float on the liquid surface after being placed in the mixing tank, it is difficult to submerge the adsorbent below the liquid surface through the mixing treatment of the mixing mechanism, so that a large amount of adsorbent will accumulate near the liquid surface, which will lead to poor coating effect.

Subsequently, the stirring element is started to stir and mix the materials in the kettle body 10.

[0031] refer to Figure 2 as well as Figure 3-Figure 8 The stirring member includes a middle cylinder 20 coaxially arranged with the kettle body 10 and a plurality of blade assemblies arranged on the outside of the middle cylinder 20. The middle cylinder 20 has a channel, and the top of the middle cylinder 20 has a plurality of nozzles 21 connected to the channel. The plurality of nozzles 21 are evenly arranged along the circumference of the middle cylinder 20. The outer periphery of the middle cylinder 20 is provided with a plurality of through holes 201 connected to the channel. The outer side of the middle cylinder 20 is coaxially slidably provided with a ring plate 40. In this embodiment, the outer wall of the middle cylinder 20 is provided with a spiral guide groove 202, and the inner ring side of the ring plate 40 has a spiral guide groove 202 connected to the spiral guide groove 202. The guide groove 202 is slidably matched with the guide rod 402, and there are two spiral guide grooves 202 and two guide rods 402 respectively. The two spiral guide grooves 202 are symmetrically arranged about the vertical plane where the axis of the middle cylinder 20 is located, and the two guide rods 402 are symmetrically arranged about the vertical plane where the axis of the ring plate 40 is located. The ring plate 40 is provided with a plurality of openings 401 that cooperate with the through hole 201. A pressing piece is provided at the upper end of the ring plate 40, and the pressing piece includes a bracket 41 fixedly connected to the ring plate 40 and a plurality of pressing plates 42 rotatably arranged on the bracket 41.

[0032] The bracket 41 is annular, and the outer ring side of the bracket 41 fits against the inner wall of the kettle body 10. A plurality of blanking openings 411 are evenly arranged along the circumference of the bracket 41. A shaft is fixed in the blanking opening 411, and the pressure plate 42 is rotatably connected to the shaft. The side of the blanking opening 411 close to the axis of the ring plate 40 is a vertical surface 412, and the side of the pressure plate 42 close to the axis of the ring plate 40 is a vertical surface 421 that cooperates with the vertical surface 412. The side of the blanking opening 411 away from the axis of the ring plate 40 is an arcuate surface 413, and the side of the pressure plate 42 away from the axis of the ring plate 40 is an arcuate surface 422 that cooperates with the arcuate surface 413. The pressure plate 42 is larger than the size of the blanking opening 411. In the initial state, the pressure plate 42 is in a vertical state under the action of gravity, and the guide rod 402 is located at the lower end of the spiral guide groove 202.

[0033] A conveying member 50 is provided for rotation in the middle cylinder 20. The conveying member 50 adopts a conveying auger. The conveying member 50 drives the middle cylinder 20 to rotate coaxially and in the opposite direction through a driving assembly. The driving assembly includes a gear 1 51 fixed coaxially with the conveying member 50, a ring gear 52 fixed coaxially on the inner ring side of the middle cylinder 20, and two gears 2 53 rotatably arranged on the top of the kettle body 10. The gear 2 53 is engaged with the gear 1 51 and the ring gear 52. A motor 11 for driving the conveying member 50 to rotate is installed on the top of the kettle body 10. It should be noted that the gear 1 51, the ring gear 52 and the gear 2 53 are all located at the top of the kettle body 10, and the top of the kettle body 10 is fixed to the mounting shaft 531 for mounting the gear 2 53.

[0034] When the motor 11 controls the conveying member 50 to rotate in the opposite direction (the conveying member 50 rotates counterclockwise when viewed from top to bottom along the axial direction of the middle cylinder 20), the middle cylinder 20 can rotate clockwise under the action of the driving assembly (viewed from top to bottom along the axial direction of the middle cylinder 20). At this time, the ring plate 40 can slide upward along the spiral guide groove 202 and move upward relative to the middle cylinder 20 until the guide rod 402 moves to the uppermost end of the spiral guide groove 202. At this time, the ring plate 40 completely blocks the through hole 201, the pressing plate 42 abuts against one side of the blanking port 411 and maintains a vertical state, the blanking port 411 is opened, and the conveying member 50 passes the solution in the kettle body 10 through the inner wall of the kettle body 10. The bottom of the channel is transported upward to the nozzle 21 and the solution is sprayed downward to the bracket 41; when the conveying member 50 rotates forward, the middle cylinder 20 can rotate counterclockwise under the action of the driving assembly. At this time, the ring plate 40 can slide downward along the spiral guide groove 202 under the action of its own weight and move downward relative to the middle cylinder 20 until the guide rod 402 moves to the lowermost end of the spiral guide groove 202. At this time, the ring plate 40 fully opens the through hole 201, and the pressure plate 42 deflects from the vertical state to the inclined state. The conveying member 50 sucks the solution in the kettle body 10 into the channel through the through hole 201 and transports it downward to impact the adsorbent at the bottom of the kettle body 10.

[0035] refer to Figure 2-Figure 4 as well as Figure 9A support ring 30 is coaxially fixed to the bottom of the kettle body 10, and a sealing member is coaxially slidably provided in the support ring 30 through an elastic member 31. The elastic member 31 adopts a spring. The middle cylinder 20 is located above the support ring 30 and is rotatably connected thereto. The sealing member includes a base frame 32 and a mesh plate 33 fixed to the lower end of the base frame 32. The mesh plate 33 is circular and fits into the opening at the bottom of the support ring 30. The outer peripheral side of the base frame 32 has a plurality of drainage ports 321 surrounded by the mesh plate 33. The elastic member 31 has a tendency to pull the sealing member upward relative to the support ring 30. In the initial state The lower end surface of the mesh plate 33 is flush with the lower end surface of the support ring 30, and the drain port 321 is blocked by the inner surface of the support ring 30; when the conveying member 50 rotates in the opposite direction, the lower end surface of the mesh plate 33 remains flush with the lower end surface of the support ring 30, and the conveying member 50 rotates forward to suck the solution in the kettle body 10 into the channel through the through hole 201 and transport it downward, so that the mesh plate 33 moves downward relative to the support ring 30 and stops at the discharge port 12, the elastic member 31 is stretched, and the drain port 321 is opened; it should be noted that the mesh holes on the mesh plate 33 are smaller than the particle size of the adsorbent particles.

[0036] refer to Figure 2 、 Figure 4 as well as Figure 10 In this embodiment, there are three groups of blade assemblies, which include a carrying ring 22 fixedly arranged on the outside of the middle cylinder 20, and a plurality of blades 23 are provided on the carrying ring 22 along its circumference. The blades 23 are rotatably connected to the carrying ring 22, and a guide plate 24 corresponding to the blades 23 is fixed on the outer periphery of the carrying ring 22. One end of the blade 23 rotatably connected to the carrying ring 22 is close to the guide plate 24, and the guide plate 24 has a V-shaped guide portion 241 on the side away from the blade 23. A limiting ring 221 is provided on the carrying ring 22 above the guide plate 24. In the initial state, the blade 23 is in a vertical state under the action of gravity. When the blade 23 swings upward from the vertical state and aligns with the lower end surface of the limiting ring 221 When the conveying member 50 is stopped, the end of the blade 23 that is rotatably connected to the carrying ring 22 is in a slightly downward tilted state; when the conveying member 50 rotates in the reverse direction, the middle cylinder 20 can rotate clockwise, so that the blade 23 can swing upward from the vertical state to the state of stopping with the lower end surface of the limit ring 221. At this time, with the assistance of the V-shaped guide part 241, the blade assembly can reduce the disturbance of the solution in the kettle body 10; when the conveying member 50 rotates forward, the middle cylinder 20 can rotate counterclockwise. At this time, the water flow can impact the blade 23 to deflect the blade 23 from the state of stopping with the lower end surface of the limit ring 221 to the vertical state. At this time, the blade assembly can increase the disturbance of the solution in the kettle body 10 to improve the mixing effect.

[0037] Specific working principle: Reference Figures 1-10, add solution into the kettle body 10 and make the liquid level just cover the bracket 41, then the motor 11 controls the conveying member 50 to rotate in the opposite direction at a relatively slow speed, and the middle cylinder 20 can rotate clockwise. Under the auxiliary action of the solution in the kettle body 10 pushing the pressure plate 42, the ring plate 40 can slide upward along the spiral guide groove 202 and move upward relative to the middle cylinder 20 until the guide rod 402 moves to the uppermost end of the spiral guide groove 202, and then add the adsorbent particles to be mixed into the kettle body 10 through the feed port until the total height of the material in the kettle body 10 is below the bracket 41. During this process, the conveying member 50 conveys the solution in the kettle body 10 upward through the mesh plate 33 at the bottom of the channel to the nozzle 21 and sprays the solution downward toward the bracket 41 to prevent the adsorbent particles from adhering to the top of the bracket 41 and the front side of the pressure plate 42 along the rotation direction of the middle cylinder 20. The blade assembly can reduce the disturbance of the solution in the kettle body 10 to prevent the adsorbent particles to be mixed from moving quickly to the discharge port 12 at the bottom of the kettle body 10.

[0038] After the adsorbent particles to be mixed are added, the conveying member 50 is controlled to rotate rapidly in the forward direction. At this time, the middle cylinder 20 can rotate rapidly counterclockwise, the bracket 41 can move downward, and the pressure plate 42 is deflected from the vertical state to the inclined state under the impact of the water flow, so that the adsorbent particles to be mixed are pressed down to below the liquid surface by the pressure plate 42, so that the adsorbent particles to be mixed can be better mixed with the solution, and it is avoided that some adsorbent particles are not evenly mixed due to floating on the liquid surface; in this process, the blade assembly can increase the disturbance of the solution in the kettle body 10 to improve High mixing effect; in addition, since the conveying member 50 can suck the solution in the kettle body 10 into the channel through the through hole 201 and convey it downward when it rotates forward, the water flow in the channel can impact the mesh plate 33 downward, so that the mesh plate 33 moves downward relative to the support ring 30 and stops at the discharge port 12, the elastic member 31 is stretched, and the discharge port 321 is opened, so that the water flow out of the discharge port 321 can recoil the material deposited at the bottom of the kettle body 10 upward, so that the adsorbent particles in the kettle body 10 can always be well mixed with the solution, thereby improving the mixing effect.

[0039] After the mixing is completed, the equipment is controlled to stop and all the materials are discharged through the discharge port 12. Then, purified water is added into the kettle body 10 through the feed port to clean the kettle body 10.

[0040] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
