Description

Technical Field

[0001] The utility model relates to the field of polysaccharide flushing liquid production, in particular to a mixing device for liquid dressings. Background Art

[0002] Biopolysaccharide flushing solution is a medical liquid dressing that can be used to flush wounds. After flushing, it can form a protective film on the wound to facilitate wound repair. The specific preparation method is as follows: the first step is to prepare an aqueous solution of sodium methylcellulose and sodium alginate, and then mix the two; the second step is to adjust the pH value of the mixed solution by acid; the third step is to control the microorganisms in the mixed solution by filtering.

[0003] Factors that affect the quality of biopolysaccharide flushing liquid include viscosity, pH and the number of microorganisms. Among them, viscosity is the key factor affecting the film formation of biopolysaccharide flushing liquid, which requires it to be neither too thin nor too thick. Viscosity is greatly affected by the accuracy of ingredients and mixing uniformity.

[0004] At present, when producing polysaccharide flushing liquid, ordinary stirring devices are mainly used for mixing. Since the mixed liquid has a certain viscosity, it has defects such as difficulty in uniform mixing and low mixing efficiency. Utility Model Content

[0006] The technical solution adopted by the utility model to solve the above technical problems is:

[0007] A mixing device for liquid dressings, comprising two mixing tanks and a mixing tank, each mixing tank is connected to the mixing tank via a pipeline, the pipeline is provided with a valve, the mixing tank is provided with a liquid level meter or / and the valve is an electromagnetic flow valve, so as to control the mixing tank to quantitatively transport the ingredients to the mixing tank;

[0008] The mixing tank includes a tank body, a dispersion component is provided at the upper part of the tank body, a stirring shaft is provided at the middle and lower part, a stirring component is connected to the stirring shaft, the dispersion component includes a sleeved inner feed tube and an outer feed tube, the feed ends of the inner feed tube and the outer feed tube are respectively connected to the pipelines of two ingredient tanks, a first conical cover is provided below the discharge end of the outer feed tube, the discharge end of the inner feed tube passes through the first conical cover and a second conical cover is provided below it, the first conical cover is fixed relative to the tank body, the second conical cover is fixed to the top of the stirring shaft, and the second conical cover is smaller than the first conical cover, so that when the second conical cover rotates with the stirring shaft, the ingredients on it are thrown out and collide and mix with the ingredients dropped from the edge of the first conical cover.

[0009] Preferably, the stirring component comprises a scraper plate matched with the inner wall of the tank body, and a stirring rod is connected between the scraper plate and the stirring shaft.

[0010] Preferably, a rubber strip is provided outside the scraper plate.

[0011] Preferably, the top height of the scraper plate is higher than the edge of the first conical cover.

[0012] Preferably, the bottom radius of the first conical cover is between 1 / 3 and 2 / 3 of the radius of the tank body.

[0013] The utility model adopts the above technical solution, and has the advantages that: the mixing device for liquid dressing can deliver ingredients more accurately through the setting of liquid level meter or flow solenoid valve; through the setting of dispersion component, the two ingredients can be collided and mixed first and then stirred and mixed, so that the mixing can not only speed up the mixing speed, but also facilitate the ingredients to be evenly mixed together. In particular, the collision force can be adjusted by adjusting the speed of the stirring shaft; and the second conical cover is smaller than the first conical cover, which can avoid the two ingredients mixing on the second conical cover to form mucus, affecting the output speed of the ingredients in the feeding inner tube.

[0020] In order to clearly illustrate the technical features of the present solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings. In the description of this specification, the description of reference terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0021] like Figure 1-3 As shown, in this embodiment, the mixing device for liquid dressing includes two mixing tanks 1 and a mixing tank 2, each mixing tank 1 is connected to the mixing tank 2 through a pipeline 3, the pipeline 3 is provided with a valve 4, the mixing tank 1 is provided with a liquid level meter 5 or / and the valve 4 adopts an electromagnetic flow valve to control the mixing tank 1 to quantitatively transport the ingredients to the mixing tank 2; the mixing tank 2 includes a tank body 21, the upper part of the tank body 21 is provided with a dispersion component 22, the middle and lower part is provided with a stirring shaft 23, the stirring shaft 23 is connected with a stirring component 24, the dispersion component 22 includes a sleeved feeding inner tube 221 and a feeding outer tube 222, the feeding inner tube 221 is provided with a stirring shaft 23, and the stirring shaft 23 is connected with a stirring component 24. The feeding ends of the tube 221 and the feeding outer tube 222 are respectively connected to the pipelines of the two material tanks 1, and a first conical cover 223 is provided below the discharging end of the feeding outer tube 222. The discharging end of the feeding inner tube 221 passes through the first conical cover 223 and a second conical cover 224 is provided below it. The first conical cover 223 is fixed relative to the tank body 21, and the second conical cover 224 is fixed to the top of the stirring shaft 23, and the second conical cover 224 is smaller than the first conical cover 223, so that when the second conical cover 224 rotates with the stirring shaft 23, the ingredients on it are thrown out and collide and mix with the ingredients dropped from the edge of the first conical cover 223.

[0022] Working principle: Start the motor connected to the stirring shaft 23, and rotate it slowly first. The two batching tanks 1 are respectively filled with mixed ingredients. When the two are mixed, one of them is fed from the inner feeding tube 221 to the mixing tank 2, which is recorded as ingredient A, and the other is fed from the outer feeding tube 222 to the mixing tank 2, which is recorded as ingredient B. Ingredient B is dispersed through the first conical cover 223 and falls from its edge. Ingredient A is rotated and thrown out through the second conical cover 224 to collide and mix with the fallen ingredient B, which not only achieves a good mixing effect, but also facilitates the rapid and uniform mixing of the two ingredients, and has a high mixing efficiency. After the two feeds are dispersed, collided and mixed, adjust the speed of the stirring shaft to quickly stir the two ingredients to speed up the mixing.

[0023] In addition, controlling the batching through a liquid level meter has good accuracy; controlling the batching through an electromagnetic flow valve also has good accuracy. You can choose one of the two to control, or you can set them at the same time, which is safer. When one of them reaches the set value, the feeding will stop.

[0024] In one of the embodiments, some ingredients will stick to the inner wall of the tank body. In order to improve the mixing uniformity and stabilize the stirring shaft, the stirring component 24 is designed to have the following structure: Specifically, the stirring component 24 includes a scraper plate 241 that cooperates with the inner wall of the tank body 21, and a stirring rod 242 is connected between the scraper plate 241 and the stirring shaft 23.

[0025] In one of the embodiments, in order to avoid rigid friction, a rubber strip 243 is provided outside the scraper plate 241 .

[0026] In one embodiment, the top height of the scraper plate 241 is higher than the edge of the first conical cover 223 so as to scrape the material on the inner wall of the tank as comprehensively as possible.

[0027] In one embodiment, the bottom radius of the first conical cover 223 is between 1 / 3 and 2 / 3 of the radius of the tank body 21. Such a design can, on the one hand, avoid the mixture after the collision from being thrown to the inner wall of the tank body as much as possible, and on the other hand, achieve a better dispersed collision mixing effect.

[0028] In one of the embodiments, a discharge pipe and a valve may be connected to the bottom of the tank to control the discharge of the mixed liquid.

[0029] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0030] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
