Description

Technical Field

[0001] The utility model relates to the technical field of mixing and stirring devices, in particular to a mixing device for hemodialysis concentrated powder. Background Art

[0002] Hemodialysis is one of the safest, easiest, and most widely used methods for blood purification. Dialysis involves the movement of solutes through a semipermeable membrane from a high-concentration solution to a low-concentration solution. Dialysis fluid or dialysis powder is primarily used for patients requiring dialysis for acute or chronic renal failure, uremia, and acute drug poisoning. Hemodialysis concentrates are available in both solid powder and liquid form. The production of hemodialysis powder requires mixing, necessitating the use of a mixing device for hemodialysis concentrate powders.

[0003] The existing patent (publication number: CN207012829U) discloses a hemodialysis concentrated powder stirring device, comprising a bracket, a barrel, an agitator, and a driving device. The barrel and the driving device are mounted on the bracket, the agitator is mounted on the barrel, the left end of the agitator is connected to the driving device, and the right end is rotatably matched with the barrel. The lower end of the barrel is provided with a discharge port. The agitator comprises a left rotating shaft, a right rotating shaft, and a stirring assembly. The left end of the stirring assembly is connected to the left rotating shaft, the right end is connected to the right rotating shaft, the right rotating shaft is rotatably matched with the barrel, and the right rotating shaft is provided with a feed port. The stirring assembly comprises at least three stirring shafts, the sides of the stirring shafts are connected by filter plates, the filter plates are provided with through holes, the side of the stirring shafts is provided with stirring plates, the side of the stirring plates is provided with notches on the side opposite to the stirring shafts, and the two ends of the stirring shafts are respectively connected to the left rotating shaft and the right rotating shaft. The utility model realizes full mixing of solid materials and liquid materials, and the mixing is very uniform. It has a simple structure, is easy to operate, and has high practical value.

[0004] The above patented technology mixes and stirs the materials through a stirring shaft, but in actual use, the stirring plate is driven to rotate by the stirring shaft alone, and the stirring direction is relatively single.

In addition, the mixing barrel is fixed, resulting in the material easily accumulating at the bottom of the mixing barrel when entering the mixing barrel for mixing, further affecting the mixing effect. Therefore, a mixing device for hemodialysis concentrated powder is proposed. Utility Model Content

[0026] In this embodiment, two vertical plates 23 are fixedly connected to the top outer surface of the base plate 1 and are symmetrically arranged on the left and right. The opposite outer surfaces of the two vertical plates 23 are rotatably connected to two connecting shafts 17.

[0033] Working principle: When the utility model is in use, the raw materials for hemodialysis powder production are put into the mixing barrel 3, and the second motor 12 is turned on. The second motor 12 drives the front support shaft 11 to rotate, and drives the front transmission wheel 18 to rotate. Under the action of the belt 19, it drives the other transmission wheel 18 to rotate, thereby rotating the front connecting shaft 17, and rotating the second gear 20 on the connecting shaft 17. The second gear 20 drives the third gear 21 to rotate, so that the rotation directions of the two connecting shafts 17 are opposite. When the rear connecting shaft 17 rotates, it drives the transmission wheel 18 thereon to rotate. Under the action of the belt 19, the second gear 20 drives the third gear 21 to rotate. The lower part drives the support shaft 11 on the rear side to rotate, and the rotation directions of the two support shafts 11 are opposite. When the front support shaft 11 rotates, it drives the winding wheel 13 thereon to rotate, and reels or spits out the steel rope 16 on the front side. When the rear support shaft 11 rotates, it drives the winding wheel 13 thereon to rotate, and spits out or reels the steel rope 16 on the rear side. As a result, with the operation of the second motor 12, the front and rear sides of the mixing barrel 3 are moved back and forth up and down, driving the hemodialysis powder inside the mixing barrel 3 to swing back and forth, thereby improving the uniformity of mixing of the hemodialysis powder raw materials inside the mixing barrel 3 and improving the mixing and stirring effect.

[0034] During the stirring and mixing process, the first motor 5 works, the first motor 5 drives the rotating shaft 6 to rotate, and drives the first gear 7 to rotate, and the first gear 7 drives the gear ring 8 to rotate, so that the mixing barrel 3 rotates inside the support sleeve 2, so that the mixing barrel can rotate while tilting up and down, and while the rotating shaft 6 rotates, it drives the synchronous pulley 9 thereon to rotate, and under the action of the synchronous toothed belt 10, drives the synchronous pulley 9 on the stirring shaft 4 to rotate, so that the stirring shaft 4 and the mixing barrel 3 rotate in opposite directions, and the stirring blades 22 are driven by the stirring shaft 4 to stir and mix the hemodialysis powder raw materials. The mixing barrel 3 can rotate while tilting up and down, further improving the mixing and stirring effect of the hemodialysis powder raw materials inside the mixing barrel 3.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
