Description

Technical Field

[0001] This utility model relates to the field of hemodialysis technology, and more specifically, to a device for dissolving hemodialysis concentrate. Background Technology

[0002] Hemodialysis, a crucial renal replacement therapy, is widely used in the treatment of patients with kidney diseases such as kidney failure. By mimicking the filtration function of the human kidney, it helps remove metabolic waste and excess water from the patient's blood, while maintaining electrolyte and acid-base balance. It plays an indispensable role in prolonging patient life and improving quality of life. During hemodialysis treatment, the hemodialysis concentrate is a vital component; its quality and solubility directly affect the safety and effectiveness of the dialysis treatment.

[0003] In existing technologies, the dissolution rate of traditional hemodialysis concentrates is generally increased by stirring blades. However, some devices have poorly designed stirring structures with dead zones, preventing some concentrates from fully contacting the solvent and resulting in incomplete dissolution. Therefore, inventing a hemodialysis concentrate dissolution device to solve these problems has become a pressing issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a dissolving device for hemodialysis concentrate, which aims to solve the problem of incomplete dissolution caused by dead zones in common stirring structures.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a dissolving device for hemodialysis concentrate, including a dissolving cylinder and a sealing cap and a spraying mechanism disposed on the dissolving cylinder, wherein a feed pipe is installed on the bottom side wall of the dissolving cylinder;

[0007] The sealing cover is sealed and fixed by bolts and a dissolving cylinder. The sealing cover has a feeding port. The upper end of the sealing cover is equipped with a mounting bracket and a fixing bracket. The upper end of the mounting bracket is equipped with a motor. One end of the mounting bracket is equipped with a gear. The inner wall of the sealing cover is equipped with a main shaft. The upper side wall of the main shaft is equipped with an external gear ring. Multiple stirring blades are installed on the side wall of the main shaft inside the dissolving cylinder. The main shaft has a hollow groove inside. The stirring blades have cavities inside. Multiple spray holes are opened on the side wall of one end of the cavity.

[0008] The spraying mechanism includes a water tank, a pump body, and a rotary joint mounted on a sealed cover.

[0009] Preferably, one end of the gear is rotatably connected to the inner wall of the mounting bracket, the output end of the motor is fixedly connected to one end of the gear, and the gear and the external gear ring are meshed together.

[0010] Preferably, the outer wall of the main shaft and the inner wall of the sealing cover are rotatably connected, the hollow groove and the interior of the cavity are in communication, a baffle is installed on the inner wall of the cavity, a second one-way valve is installed on the inner wall of the baffle, and the baffle divides the side of the cavity near the spray hole into a liquid storage chamber.

[0011] Preferably, the pump body's pumping end is connected to the interior of the water tank, the pump body's outlet end is equipped with a transmission pipe that is fixedly connected to the rotary joint, the outer wall of the transmission pipe is fixedly connected to the inner wall of the fixing frame, and the interior of the transmission pipe is connected to the hollow groove.

[0012] By adopting the above technical solution, the stirring blade rotates to stir and mix the solution and concentrated powder, causing the concentrated powder to move irregularly in the solvent. This breaks up the original aggregated state of the solute, allowing the concentrated powder to fully contact the solvent, thereby increasing the dissolution rate. At the same time, the solvent in the tank is sprayed outward at high speed through multiple nozzles in the stirring blade, so that it is evenly dispersed in the stirring area and fully contacts the concentrated powder being stirred. The impact force of the solvent washes and erodes the concentrated powder, breaking up the agglomeration state, further improving the dissolution rate.

[0013] Preferably, a hollow cover is installed at the lower end of the spindle, and the interior of the hollow cover is connected to the interior of the hollow groove.

[0014] Preferably, an mounting plate is installed near the inner wall of the hollow shroud, and a first one-way valve is installed on the inner wall of the mounting plate.

[0015] Preferably, the bottom inner wall of the hollow hood is equipped with a plurality of first nozzles, second nozzles and third nozzles, wherein the first nozzles are arranged vertically downwards, and the second nozzles and third nozzles are arranged at different angles toward the dissolving cylinder.

[0016] By adopting the above technical solution, the hollow cover set at the lower end of the main shaft, together with the multiple nozzles installed on the inner wall, sprays the concentrated powder at the bottom of the cylinder while it is working, thereby avoiding the clumping of the concentrated powder in the dead corner of the stirring and reducing the occurrence of incomplete dissolution.

[0017] The beneficial effects of this utility model are:

[0018] The hollow groove in the main shaft, combined with the cavity and nozzle in the stirring blade, drives the pump to spray the solvent at high speed through the nozzle to the surrounding solute, ensuring it is evenly dispersed in the stirring area and makes full contact with the concentrated powder being stirred. The impact force of the solvent washes and erodes, breaking up the clumps of the concentrated powder and further improving the dissolution rate. At the same time, the hollow cover at the lower end of the main shaft, together with the multiple nozzles at different angles installed on its inner wall, sprays and disperses the concentrated powder in the space below without dead angles, thus preventing the concentrated powder from clumping in the dead corners of the stirring, reducing the occurrence of incomplete dissolution, and further improving the dissolution rate.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. 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.

[0029] Example, refer to Figures 1-7 A dissolving device for hemodialysis concentrate includes a dissolving cylinder 1, a sealing cap 2 disposed on the dissolving cylinder 1, and a spraying mechanism. A feed pipe 11 is installed on the bottom side wall of the dissolving cylinder 1.

[0030] The sealing cover 2 is sealed and fixed to the dissolving cylinder 1 by bolts. The sealing cover 2 has a feeding port 21. The upper end of the sealing cover 2 is respectively equipped with a mounting bracket 22 and a fixing bracket 23. The upper end of the mounting bracket 22 is equipped with a motor 3. One end of the mounting bracket 22 is equipped with a gear 4. The inner wall of the sealing cover 2 is equipped with a main shaft 5. The upper side wall of the main shaft 5 is equipped with an external gear ring 54. Multiple stirring blades 6 are installed on the side wall of the main shaft 5 inside the dissolving cylinder 1. The inside of the main shaft 5 is equipped with a hollow groove 51. The inside of the stirring blades 6 is equipped with a cavity 61. One end of the side wall of the cavity 61 is equipped with multiple spray holes 631.

[0031] The spraying mechanism includes a water tank 7, a pump body 8, and a rotary joint 82, all mounted on a sealing cover 2.

[0032] Furthermore; one end of gear 4 is rotatably connected to the inner wall of mounting bracket 22, the output end of motor 3 is fixedly connected to one end of gear 4, gear 4 and external gear ring 54 are meshed, the outer wall of main shaft 5 is rotatably connected to the inner wall of sealing cover 2, the hollow groove 51 and the interior of cavity 61 are connected, a baffle 62 is installed on the inner wall of cavity 61, a second one-way valve 621 is installed on the inner wall of baffle 62, baffle 62 divides the side of cavity 61 near spray hole 631 into liquid storage chamber 63, the pump body 8's pumping end is connected to the interior of water tank 7, the pump body 8's outlet end is installed with a transmission pipe 81 fixedly connected to rotary joint 82, the outer wall of transmission pipe 81 is fixedly connected to the inner wall of mounting bracket 23, and the interior of transmission pipe 81 is connected to hollow groove 51.

[0033] It should be noted that: various separately stored raw material powders are fed into the dissolving cylinder 1 through the feeding port 21, followed by the addition of some solvent. During this process, the raw materials at the bottom of the cylinder are brought into contact with each other for initial mixing. Then, the motor 3 is started to control the gear 4 to mesh with the external gear ring 54 and rotate. The external gear ring 54 drives the main shaft 5 to rotate, causing the stirring blade 6 to rotate and mix the solution and concentrated powder. This causes the concentrated powder to move irregularly in the solvent, breaking up the original aggregated state of the solute and ensuring that the concentrated powder is in full contact with the solvent, thereby increasing the dissolution rate. At the same time as stirring, the pump body 8 is started to draw solvent from the water tank 7 and enter the cavity 61 in the stirring blade 6 through the hollow groove 51. During the rotation, under pressure, the solvent is sprayed outward at high speed through multiple nozzles 631 on one side, so that it is evenly dispersed in the stirring area and comes into full contact with the concentrated powder being stirred. The impact force of the solvent washes and erodes the concentrated powder, breaking up the agglomeration state of the concentrated powder and further increasing the dissolution rate.

[0034] Furthermore, a hollow cover 52 is installed at the lower end of the main shaft 5. The interior of the hollow cover 52 is connected to the interior of the hollow groove 51. An installation plate 53 is installed on the inner wall of the hollow groove 51 near the hollow cover 52. A first one-way valve 531 is installed on the inner wall of the installation plate 53. Multiple first nozzles 521, second nozzles 522 and third nozzles 523 are installed on the inner wall of the bottom end of the hollow cover 52. The first nozzles 521 are set vertically downward. The second nozzles 522 and third nozzles 523 are set at different angles toward the dissolving cylinder 1.

[0035] It should be noted that a valve body and a sealing plug can be installed on the feed pipe 11 to control its opening and closing. The hollow cover 52 set at the lower end of the main shaft 5, together with the multiple nozzles installed on the inner wall, sprays the concentrated powder at the bottom of the cylinder while it is working, so as to avoid the concentrated powder in the dead corner of the stirring from clumping and reduce the occurrence of incomplete dissolution. At the same time, the different spray angles set by the first nozzle 521, the second nozzle 522, and the third nozzle 523 can spray and disperse the concentrated powder in the space below without dead corners during the rotation, further improving the dissolution speed.

[0036] The working principle of a device for dissolving hemodialysis concentrate:

[0037] Concentrated powder is fed into dissolving cylinder 1 through feed port 21, followed by the addition of some solvent. Motor 3 is started to control gear 4 to mesh with external gear ring 54, causing it to rotate. External gear ring 54 drives main shaft 5 to rotate, causing stirring blade 6 to rotate and mix the solution and concentrated powder. This causes the concentrated powder to move irregularly within the solvent, breaking up the original aggregated state of the solute and ensuring full contact between the concentrated powder and the solvent, thereby increasing the dissolution rate. Simultaneously, pump 8 is started to draw solvent from water tank 7 and through hollow groove 51 into cavity 61 in stirring blade 6. During rotation, under pressure, the solvent is propelled through multiple nozzles 631 on one side... The high-speed spray from the outer side ensures even dispersion within the stirring area. Simultaneously, the hollow cover 52 at the lower end of the main shaft 5, along with multiple nozzles installed on the inner wall, sprays the concentrated powder at the bottom of the cylinder during operation. This prevents the concentrated powder from clumping in the stirring dead corners, reducing the occurrence of incomplete dissolution. Furthermore, the different spray angles of the first nozzle 521, the second nozzle 522, and the third nozzle 523 allow for thorough spraying and dispersing of the concentrated powder in the space below during rotation, ensuring full contact with the concentrated powder being stirred. The impact force of the solvent washes and erodes, breaking up the clumping of the concentrated powder and further improving the dissolution rate.

[0038] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
