Description

Technical Field

[0001] The present invention relates to the technical field of mixing and stirring, and specifically to a mixing device and process for hemodialysis concentrate. Background Art

[0002] Hemodialysis concentrate is mainly prepared by mixing two kinds of solutions, namely solution A and solution B. Solution A is mainly an acidic solution, and solution B is mainly an alkaline solution. Solution A is responsible for adjusting the body fluid components to ensure the stability of ion concentration; solution B is responsible for maintaining acid-base balance to ensure the safety and effectiveness of hemodialysis.

[0003] Before solution A and solution B are mixed, they each have a relatively long shelf life. However, once they are mixed together, due to the influence of chemical reactions, microbial growth, or other physical and chemical processes, the stability of the mixed solution will decrease, and the shelf life will be correspondingly shortened. Therefore, in practice, solution A and solution B are generally mixed and manufactured separately using two sets of independent devices.

Detailed implementation manners

[0038] 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 the embodiments. 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.

[0039] Please refer to Figure 1 and Figure 2, an embodiment of the present invention provides a mixing device for hemodialysis concentrate, including a machine platform 101. There are two shunt mixing units arranged inside the machine platform 101, and a discharging mixing unit 5 is arranged at one end inside the machine platform 101; a feeding mechanism 6 is arranged on one side of the top of the machine platform 101. Please refer to Figure 7 and Figure 8 , the feeding mechanism 6 includes a feeding hopper 601. A blanking pipe 609 is arranged below the feeding hopper 601. There are several shunt channels 610 arranged inside the blanking pipe 609. A shunt assembly is arranged at the bottom of the blanking pipe 609. The shunt assembly is used to guide the materials sent out by the blanking pipe 609 to one of the shunt mixing units. In the feeding mechanism 6 of this application, by arranging the blanking pipe 609 and the shunt channels 610, different types of materials are separately transported, and according to actual production needs, the shunt assembly is used to shunt and guide various materials, so that each shunt mixing unit can simultaneously perform the mixing operation of materials with different proportions and types, and the use flexibility is stronger; in this embodiment, an inner cavity partition 102 is also arranged inside the machine platform 101, which is used to separate the two shunt mixing units and the discharging mixing unit 5, so as to facilitate the separate and independent control of environmental conditions such as temperature in the separated areas, so that each unit can perform the mixing operation at its respective optimal environmental temperature.

[0040] Please refer to Figure 2 , the shunt mixing unit includes a pre-mixing assembly 2 and a post-mixing assembly 3. The pre-mixing assembly 2 is used to mix materials with dialysis water to obtain a mixture for convenient transportation, and the post-mixing assembly 3 is used to mix and stir the mixture; thus, two-stage mixing and stirring can be applied through the cooperation of the two to improve the mixing uniformity of the materials.

[0041] Please refer to Figure 2 and Figure 9 , the pre-mixing assembly 2 includes a stirring barrel 201. A feed inlet is opened at the center of the top of the stirring barrel 201. A water inlet pipe 206 is fixedly connected to one side of the top of the stirring barrel 201; the pre-mixing assembly 2 of this application has two working states; one is: the materials sent by the shunt assembly are connected through the feed inlet and the dialysis water is sent through the water inlet pipe 206 to realize the preliminary mixing of the materials; the other is that only the dialysis water is connected through the water inlet pipe 206, and the cleaning of the overall structure inside the shunt mixing unit is realized by cooperating with the stirring functions of the pre-mixing assembly 2 and the post-mixing assembly 3.

[0042] Please refer to Figure 7 and Figure 8, on the inner wall of the feed hopper 601 of the feeding mechanism 6 of the present application, several feed partitions 602 are fixedly connected. The feed partitions 602 divide the inner cavity of the feed hopper 601 into several feed cavities, and different types of materials are separated and stored through different feed cavities; feeding ports are opened at the bottoms of several feed cavities, and the bottoms of several feeding ports are communicated with the tops of several flow channels 610. A feed cover plate is slidably connected to the top of the feed hopper 601. When replenishing materials, the feed cover plate is slid open for material replenishment operation.

[0043] To control the feeding speed of the feed cavity, feeding rollers 604 are rotatably installed on the inner walls of several feeding ports. Feeding blocks protrude from the outside of the feeding rollers 604. A guide plate 603 is fixedly connected to the bottom of the inner wall of the feed cavity. The top of the guide plate 603 is inclined, and the height of the side facing the feeding port is lower.

[0044] To achieve quantitative weighing of different types of materials, weighing components are arranged at the tops of several flow channels 610. The weighing component includes a flipping motor 605. The output end of the flipping motor 605 is fixedly connected to a weighing frame 606. A weighing sensor 607 is fixedly installed in the middle of the weighing frame 606. A contact block 617 is fixedly connected to the inner wall of the flow channel 610 away from the flipping motor 605. The gap between the end of the weighing frame 606 and the inner wall of the material distribution channel is shielded by the contact block 617 to prevent material leakage.

[0045] Please refer to Figure 8 , on both sides of the discharge pipe 609, diversion pipes 615 are fixedly connected. The two diversion pipes 615 are respectively arranged corresponding to the two feeding ports. The diversion component includes a diversion motor 613. The output end of the diversion motor 613 is fixedly connected to a diversion plate 612. By driving the diversion plate 612 to rotate and tilt to one side by the diversion motor 613, the material is sent into the diversion pipe 615; a diversion block 616 is fixedly connected to the area between the two diversion pipes 615. The two sides of the top of the diversion block 616 are inclined to facilitate guiding the material sent out by the discharge pipe 609 to the diversion pipes 615 on both sides;

[0046] If the flow splitter plate 612 is set as a solid plate, during the falling process of the material, it can only fall from the edge of the flow splitter plate 612. Since the distance between the edge of the flow splitter plate 612 and the inner wall of the blanking pipe 609 is small, the blanking and splitting speed is slow. Therefore, for the convenience of the falling operation of the material in this application, a flow splitting port is opened in the middle of the flow splitter plate 612. A flow splitting guide rail 618 is fixedly installed on the inner wall of the flow splitting port, and a partition plate 614 is slidably installed on the inner wall of the flow splitting guide rail 618. The length of the partition plate 614 is less than the length of the flow splitting port. The flow splitting guide rail 618 is a linear guide rail with a power and control system, and is implemented by using existing technical means; the partition plate 614 is driven to move by the flow splitting guide rail 618 to open and cover the flow splitting port, so as to realize the directional splitting operation of the material.

[0047] For the pre-mixing assembly 2, except for what is mentioned above, which includes a mixing barrel 201 and a feeding port opened at the center of the top of the mixing barrel 201, and a water inlet pipe 206 fixedly connected to one side of the top of the mixing barrel 201, the specific structures for realizing the mixing function can all be implemented by referring to existing technical means.

[0048] This application provides a possible specific structure of the pre-mixing assembly 2; please refer to Figure 9 , in this application, a partition plate 203 is fixedly connected to the middle of the inner wall of the mixing barrel 201. A mixing motor 202 is arranged below the partition plate 203, and an output end of the mixing motor 202 is fixedly connected to a cross frame 204, so as to drive the cross frame 204 to rotate through the mixing motor 202 to realize the preliminary mixing of the material and water; to improve the mixing uniformity; several pushing plates 205 are fixedly connected to the middle of the cross frame 204, and the several pushing plates 205 are arranged in a staggered manner.

[0049] Please refer to Figure 2 , to realize the delivery of the mixture obtained after the pre-mixing assembly is mixed, a delivery pipe is fixedly connected to one side of the mixing barrel 201, a delivery pump 207 is fixedly installed in the middle of the delivery pipe, and an output end of the delivery pump 207 is fixedly connected to a feeding hose 306.

[0050] Please refer to Figure 3 and Figure 4 , the post-mixing assembly 3 includes a mixing tank 301. One end of the feeding hose 306 is fixedly connected to one end of the mixing tank 301, a feeding control valve 307 is fixedly installed at the connection position of the mixing tank 301 and the feeding hose 306, a mixing motor 302 is fixedly installed at the bottom of the mixing tank 301, and an output end of the mixing motor 302 is fixedly installed with a mixing member, and the mixing member is located in the mixing tank 301; the mixing motor 302 drives the mixing member to rotate to realize the mixing of the mixture in the mixing tank 301, and both the mixing motor 302 and the mixing member can be implemented by using existing technical means.

[0051] The main way for this application to improve the mixing uniformity of the rear mixing component 3 is as follows: Adjusting components 4 for adjusting the attitude of the mixing tank 301 are provided on both sides of the inner wall of the machine platform 101. Please refer to Figure 5 , the adjusting component 4 includes an adjusting motor 401. The output end of the adjusting motor 401 is fixedly connected with a mounting frame 402. Both ends of the mounting frame 402 are fixedly connected with displacement supporting rings 404. The inner wall of the displacement supporting ring 404 is slidably connected with the mixing tank 301. A displacement cylinder 403 is fixedly installed in the middle of the mounting frame 402. The output end of the displacement cylinder 403 is fixedly connected with the middle of the mixing tank 301 through a fixing frame 405; a displacement sliding groove 309 for the displacement supporting ring 404 to slide is opened on the outer wall of the mixing tank 301. During the mixing process, the attitude of the mixing tank 301 is changed by using the adjusting component 4, thereby changing the distribution position of the materials in the mixing tank 301, enabling the mixing member to fully contact the materials at different positions, and improving the mixing effect of the mixture; specifically, in this application, the adjusting motor 401 drives the entire mounting frame 402 to reciprocally rotate within a certain angle, thereby driving the entire mixing tank 301 to rotate, and cooperating with the driving of the displacement cylinder 403 to move the mixing tank 301, changing the contact position between the displacement supporting ring 404 and the mixing tank 301, and further changing the rotation center of the mixing tank 301, so that the rotational centrifugal forces of the materials at different positions in the mixing tank 301 are different during the rotation process. Furthermore, by changing the rotation center, the adjustment of the centrifugal force can be used to achieve more effective and uniform dispersion of the materials; taking the angle between the mounting frame 402 and the horizontal position as the 0-degree reference line, in this application, the angle range for the adjusting motor 401 to drive the entire mounting frame 402 to rotate is between -40 degrees and 40 degrees.

[0052] Please refer to Figure 4 , this application provides a possible structure of a mixing member. The mixing member includes a transmission rod 303. A plurality of mixing rods 304 are fixedly connected to the middle of the transmission rod 303. One end of the plurality of mixing rods 304 is fixedly connected with a movable frame. A mixing blade 305 is rotatably installed on the inner wall of the movable frame. In this application, by rotatably arranging the mixing blade 305, during the process of adjusting the attitude of the mixing tank 301, the attitude of the mixing blade 305 can change accordingly under the action of gravity, thereby adjusting the mixing effect of the mixing blade 305 and avoiding the problem of insufficient mixing of the materials caused by the mixing member rotating along a fixed track for a long time.

[0053] If mixing blades 305 in the shape of thin sheets or sharp shapes are used, when they move at high speeds, they will cut the liquid, increasing the surface area of the liquid, making it easier for the gas dissolved in the liquid to precipitate and form bubbles. At the same time, these shapes may also cause an increase in local turbulence of the liquid, further promoting the formation of bubbles, which is not conducive to the full progress of mixing and also affects the quality of the output mixing product.

[0054] The stirring blade 305 is configured as a hemispherical thin sheet, and the smooth curved surface can reduce the cutting of the liquid and local turbulence, thereby reducing the possibility of bubble generation; it helps to make the liquid flow more smoothly and reduce the formation and accumulation of bubbles; through openings are opened on both sides of the stirring blade 305, and the inner wall edges of the through openings are configured as arc-shaped surfaces to reduce the resistance of the material when passing through the through openings; in order to improve the ability of gravity to adjust the posture of the stirring blade 305, a counterweight block is fixedly connected to the bottom of the stirring blade 305, and the traction force of the stirring blade 305 and the counterweight block is used to drive the stirring blade 305 to rotate.

[0055] See also Figure 2 and Figure 6 The discharging and mixing unit 5 includes a vertical stirring disk 501, and the thickness of the vertical stirring disk 501 is smaller than its diameter, so that the vertical stirring disk 501 is flat as a whole, so that the materials stored therein can be flattened and dispersed, thereby effectively avoiding material agglomeration and improving stirring uniformity; on this basis, the upper part of the vertical stirring disk 501 is sealed and protected by the end cover plate 104, and a support frame 510 is fixedly connected between the outer wall of the vertical stirring disk 501 and the machine platform 101, so as to ensure the stability of the position of the vertical stirring disk 501; a driving motor 502 is fixedly installed on one side of the vertical stirring disk 501, and a central frame 503 is fixedly connected to the output end of the driving motor 502, and a plurality of movable rods 504 are fixedly connected to the edge of the central frame 503, and one end of the plurality of movable rods 504 is fixedly connected to an arc plate 509, and one side of the arc plate 509 is in close contact with one side of the vertical stirring disk 501, and the width of the arc plate 509 is equal to the inner wall of the vertical stirring disk 501. The cavity width is consistent; a discharge hose 311 is fixedly connected to one side of the stirring tank 301, a discharge pump 312 is fixedly installed at one end of the discharge hose 311, a discharge control valve 310 is fixedly installed at the connection position between the discharge hose 311 and the stirring tank 301, the output end of the discharge pump 312 is fixedly connected to one side of the vertical stirring disk 501 through a discharge pipe, and a closing valve 313 is fixedly installed at the connection position between the discharge pipe and the vertical stirring disk 501. After the material to be mixed is sent into the vertical stirring disk 501, the port where the discharge pipe is located is closed by the closing valve 313; the bottom of the vertical stirring disk 501 is fixedly connected with a delivery pipe 103; the discharge mixing unit 5 can be used to achieve re-mixing of the material delivered by the post-mixing component 3, so as to improve the uniformity of the material; when necessary, the two post-mixing units can directly deliver liquid A and liquid B respectively, so as to complete the mixing of liquid A and liquid B and directly produce the finished product of hemodialysis concentrate; to meet different usage needs.

[0056] See also Figure 6, to improve the stirring ability of the materials in the inner cavity of the vertical stirring disc 501, in this application, adjusting pieces 508 are slidably connected to the middle parts of a number of movable rods 504. A number of traction motors 505 are arranged inside the central frame 503. The output ends of the traction motors 505 are fixedly connected with winding rods 506. A traction rope 507 is fixedly connected to the middle part of the winding rod 506. One end of the traction rope 507 is fixedly connected with the adjusting piece 508. By driving the winding rod 506 to rotate with the traction motor 505, the traction rope 507 is driven to rotate, so as to realize the traction and displacement of the adjusting piece 508, and further realize the full stirring and dispersion of the materials at different positions in the inner cavity of the vertical stirring disc 501; the adjusting piece 508 is inclined. During the rotation process, it can move away from the central frame 503 under the action of centrifugal force and the impact of the materials, so as to cooperate with structures such as the traction motor 505 to realize the adjustment of the position of the adjusting piece 508.

[0057] When the present invention is in use, the feeding cover plate is opened, and the materials are put into the feeding hopper 601. Different types of materials are stored in different feeding cavities respectively. When a certain material needs to be used, the feeding roller rotates to guide the material to pass through the feeding port and enter the flow dividing channel 610 in the feeding pipe 609, and is received by the weighing frame 606 of the weighing assembly. After being quantitatively weighed by the weighing sensor 607, the weighing frame 606 is driven to turn over by the turning motor 605 to send the material downward; then it is received and divided by the flow dividing plate 612 of the flow dividing assembly. The flow dividing motor 613 drives the flow dividing plate 612 to rotate to one side. At the same time, the partition plate 614 is driven by the flow dividing guide rail 618 to move towards the end where the flow dividing plate 612 rotates and lifts, and the flow dividing port is opened, so that the material falls into the flow dividing pipe 615 and is sent into the flow dividing and mixing unit.

[0058] The pre-mixing assembly 2 of the flow dividing and mixing unit receives the materials. Then, an external dialysis water supply device sends water into the stirring barrel 201 through the water inlet pipe 206. Then the stirring motor 202 is started to drive the cross frame 204 to rotate, so as to realize the preliminary mixing of the dialysis water and the materials.
