Description

Technical Field

[0001] This utility model relates to the field of liquid preparation tank technology, specifically a liquid preparation tank for hemodialysis concentrate. Background Technology

[0002] Hemodialysis concentrate is an important component of the dialysate used in hemodialysis treatment. It is mainly used to mix with dialysis water in a certain proportion to prepare dialysate. Hemodialysis concentrate requires the combination of several materials. In a common mixing tank, different concentrates are put into the tank and then stirred directly. However, most powdered materials tend to absorb water quickly and clump together when they enter the mixture. Clumped powdery materials are difficult to stir and can cause problems such as particles in the concentrate. Utility Model Content

[0003] The purpose of this invention is to provide a dispensing tank for hemodialysis concentrates to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mixing tank for hemodialysis concentrate, comprising a tank body, a drain pipe connected to the bottom end of the tank body, a powder feed pipe and a liquid feed pipe connected to the outer wall of the tank body, a drive motor fixedly installed at the top of the tank body, a main shaft fixedly installed at the output end of the drive motor, the main shaft extending into the tank body, a receiving tray fixedly installed on the outer wall of the main shaft, a filter cylinder fixedly installed at the bottom of the receiving tray, the interior of the filter cylinder communicating with the interior of the receiving tray, a secondary stirring assembly provided inside the filter cylinder, a main stirring shaft fixedly installed on the outer wall of the main shaft, and a drain valve provided at the connection between the drain pipe and the tank body.

[0005] Furthermore, the auxiliary stirring assembly includes a secondary shaft and a rotating disk. The rotating disk is fixedly installed on the outer wall of the main shaft and is located above the receiving disk. The secondary shaft is rotatably connected to the rotating disk through a bearing. One end of the secondary shaft extends into the filter cylinder. A secondary stirring blade is fixedly installed on the outer wall of the secondary shaft. A gear is fixedly installed on the outer wall of the secondary shaft, and the gear meshes with an internal gear ring. The internal gear ring is fixedly installed on the inner wall of the tank.

[0006] Furthermore, the connection between the tank body and the powder feed pipe is located between the rotating disk and the receiving disk, and the connection between the tank body and the liquid feed pipe is located below the receiving disk.

[0007] Furthermore, four filter cartridges are provided, and they are arranged in a circumferential array on the receiving tray.

[0008] Furthermore, the receiving tray is provided with an integrally formed guiding protrusion inside, which guides the powder to the connection between the filter cylinder and the receiving tray.

[0009] Furthermore, a hook-shaped stirring rod is fixedly installed at the bottom end of the secondary shaft, and a dispersing rod is fixedly installed on the outer wall of the secondary shaft. Multiple dispersing rods are provided and distributed at different positions on the secondary shaft. Multiple dispersing blades are rotatably provided on the outer wall of the dispersing rods through a pin.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The powder and liquid in the filter cylinder are stirred by the auxiliary stirring component. When the powder absorbs water and clumps together, the granular material cannot pass through the filter cylinder. It will only be stirred by the auxiliary stirring component and then dissolved in the liquid. Combining stirring and filtration can improve the dissolution efficiency and achieve the purpose of continuous mixing during the stirring process.

[0012] 2. Because the receiving tray is fixedly connected to the main shaft, the receiving tray can rotate synchronously when the main shaft drives the main stirring shaft to rotate, so that the filter cylinder makes a circular motion, allowing the liquid in the tank to quickly enter and exit the filter cylinder, and can carry the dissolved powder material out of the filter cylinder more quickly, thereby avoiding the problem of liquid saturation in the filter cylinder. At the same time, the fast-flowing liquid and the auxiliary stirring component can better dissolve the powder and break up powder clumps, which can improve the dissolution efficiency.

[0013] 3. When the main shaft rotates, it can drive the rotating disk and the receiving disk to rotate synchronously, which in turn drives the filter cylinder and the secondary shaft to perform synchronous circumferential motion. When the secondary shaft moves, the internal gear ring drives the gear to rotate, which in turn drives the secondary shaft to rotate, causing the secondary stirring blades on the secondary shaft to rotate, stirring the powder and liquid in the filter cylinder and accelerating the rate at which the powder dissolves in the liquid.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a mixing tank for hemodialysis concentrate, comprising a tank body 1, a drain pipe 2 connected to the bottom of the tank body 1, a powder feed pipe 3 and a liquid feed pipe 4 connected to the outer wall of the tank body 1, a drive motor 5 fixedly installed at the top of the tank body 1, a main shaft 6 fixedly installed at the output end of the drive motor 5, the main shaft 6 extending into the tank body 1, a receiving tray 7 fixedly installed on the outer wall of the main shaft 6, a filter cylinder 8 fixedly installed at the bottom of the receiving tray 7, the interior of the filter cylinder 8 communicating with the interior of the receiving tray 7, a secondary stirring assembly 9 provided inside the filter cylinder 8, a main stirring shaft 10 fixedly installed on the outer wall of the main shaft 6, a drain valve provided at the connection between the drain pipe 2 and the tank body 1, powder material is added to the tank body 1 through the powder feed pipe 3, and liquid material and dialysis water are added through the liquid feed pipe 4. The powder material is collected in the tank 1 by the receiving tray 7 and then guided into the filter cylinder 8. The auxiliary stirring component 9 stirs the powder material and liquid in the filter cylinder 8. When the powder absorbs water and clumps together, the particles cannot pass through the filter cylinder 8 and are only stirred by the auxiliary stirring component 9 and dissolved in the liquid. Since the receiving tray 7 is fixedly connected to the main shaft 6, the receiving tray 7 can rotate synchronously when the main shaft 6 drives the main stirring shaft 10 to rotate, so that the filter cylinder 8 makes a circular motion. This allows the liquid in the tank 1 to quickly enter and exit the filter cylinder 8, and can carry the dissolved powder material out of the filter cylinder 8 more quickly, thereby avoiding the problem of liquid saturation in the filter cylinder 8. At the same time, the fast-flowing liquid and the auxiliary stirring component 9 can better dissolve the powder and break up the powder clumps, which can improve the dissolution efficiency.

[0022] The auxiliary stirring assembly 9 includes a secondary shaft 901 and a rotating disk 906. The rotating disk 906 is fixedly installed on the outer wall of the main shaft 6 and is located above the receiving disk 7. The secondary shaft 901 is rotatably connected to the rotating disk 906 through a bearing. One end of the secondary shaft 901 extends into the filter cylinder 8. A secondary stirring blade 902 is fixedly installed on the outer wall of the secondary shaft 901. A gear 907 is fixedly installed on the outer wall of the secondary shaft 901. The gear 907 meshes with an internal gear ring 908. The internal gear ring 908 is fixedly installed on the inner wall of the tank 1. When the main shaft 6 rotates, it can drive the rotating disk 906 and the receiving disk 7 to rotate synchronously, thereby driving the filter cylinder 8 and the secondary shaft 901 to perform synchronous circumferential motion. When the secondary shaft 901 moves, the internal gear ring 908 pushes the gear 907 to rotate, thereby driving the secondary shaft 901 to rotate, causing the secondary stirring blade 902 on the secondary shaft 901 to rotate, stirring the powder and liquid in the filter cylinder 8 and accelerating the rate at which the powder dissolves in the liquid.

[0023] The connection between the tank body 1 and the powder feed pipe 3 is located between the rotating disk 906 and the receiving tray 7, and the connection between the tank body 1 and the liquid feed pipe 4 is located below the receiving tray 7. This design ensures that the powder material added from the powder feed pipe 3 falls onto the receiving tray 7 and then enters the filter cartridge 8.

[0024] There are four filter cylinders 8, which are arranged in a circumferential array on the receiving tray 7. The four filter cylinders 8 are used to distribute the dissolution of powder materials, so as to avoid all the powder materials entering the same stirring range, which would make the stirring more difficult.

[0025] The receiving tray 7 has an integrally formed guide protrusion 701 inside. The guide protrusion 701 guides the powder to the connection between the filter cylinder 8 and the receiving tray 7. The secondary shaft 901 ensures that the powder entering the receiving tray 7 can be guided into the filter cylinder 8. When the receiving tray 7 rotates, under the influence of centrifugal force, the powder can also be prevented from accumulating in the receiving tray 7.

[0026] A hook-shaped stirring rod 905 is fixedly installed at the bottom end of the secondary shaft 901, and a dispersing rod 903 is fixedly installed on the outer wall of the secondary shaft 901. Multiple dispersing rods 903 are provided and distributed at different positions on the secondary shaft 901. Multiple dispersing blades 904 are rotatably provided on the outer wall of the dispersing rod 903 through a pin. By rotating the secondary shaft 901, the hook-shaped stirring rod 905 is driven to rotate, which is used to stir the agglomerated material that has settled in the filter cylinder 8, so that the agglomerated material is stirred and fully contacts the liquid. When the secondary stirring blades 902 rotate, they drive the dispersing rods 903 to rotate, which in turn drives the dispersing blades 904 to rotate, which is used to break up the agglomerated material.

[0027] Working principle: In use, first, add dialysis water and liquid materials into tank 1. Then, turn on drive motor 5 to drive main shaft 6 to rotate. The rotation of main shaft 6 drives main stirring shaft 10 to stir dialysis water and liquid materials. Then, powder materials are added from powder feed pipe 3. After the powder materials fall onto receiving tray 7, they are guided by guide protrusion 701 into filter cylinder 8. At this time, the rotation of main shaft 6 drives rotating disk 906 and receiving tray 7 to rotate synchronously, thereby driving filter cylinder 8 and secondary shaft 901 to perform synchronous circumferential motion. When secondary shaft 901 moves, internal gear ring 908 pushes gear 907 to rotate, thereby driving secondary shaft 901 to rotate. The rotation of shaft 901 causes the auxiliary stirring blades 902 on the secondary shaft 901 to rotate, stirring the powder and liquid in the filter cylinder 8. When the main shaft 6 drives the main stirring shaft 10 to rotate, the receiving plate 7 can rotate synchronously, causing the filter cylinder 8 to make a circular motion. This allows the liquid in the tank 1 to quickly enter and exit the filter cylinder 8, and can more quickly carry the dissolved powder out of the filter cylinder 8, thus avoiding the problem of liquid saturation in the filter cylinder 8. At the same time, the fast-flowing liquid, in conjunction with the auxiliary stirring component 9, can better dissolve the powder and break up powder clumps, improving the dissolution efficiency until the stirring is completed and the dialysis concentrate is mixed.

[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
