Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of liquid medicine preparation, and specifically relates to a homogenizing stirring equipment. BACKGROUND

[0002] In the pharmaceutical field, the preparation process of liquid medicine is crucial, and homogenizing stirring is one of the key links of liquid medicine preparation. The purpose of homogenizing stirring is to uniformly mix various components in the liquid medicine, ensuring the quality stability and consistency of drug efficacy. Especially for liquid medicine containing solid substances, uniform mixing can better disperse the effective components of the medicine, improving the bioavailability and therapeutic effect of the medicine.

[0003] Currently, in the homogenizing stirring process of liquid medicine, homogenizing machines and stirring blades are commonly used to achieve mixing operation. However, it is found in actual production that the solid substances in the liquid medicine are not easy to be bound. This is because the physical properties (such as density, shape, particle size, etc.) of solid substances are greatly different from the liquid components in the liquid medicine, making it difficult for solid substances to be fully mixed with liquid under the stirring action of homogenizing machines and stirring blades. On the one hand, solid substances may agglomerate during stirring, forming larger particle groups that are difficult to be further dispersed; on the other hand, due to the limitations of the action mode and flow field characteristics of the stirring equipment, solid substances may not be effectively captured and driven, resulting in uneven distribution in the liquid medicine.

[0004] This situation of solid substances not being easy to be bound and mixed directly affects the efficiency of homogenizing stirring. Inefficient homogenizing stirring not only prolongs the production cycle and increases production costs, but also may lead to unstable liquid medicine quality, affecting the safety and effectiveness of the medicine. In addition, for some liquid medicines with high requirements for mixing uniformity, such as injections, insufficient homogenizing stirring may cause serious quality problems, even endangering the health of patients, therefore, how to solve the problem of solid substances in the liquid medicine not being easy to be bound and mixed and improve the efficiency of homogenizing stirring is an important issue to be solved in the field of liquid medicine preparation.

DETAILED DESCRIPTION

[0022] In order to better understand the utility model, the contents of the utility model are further illustrated below in combination with examples, but the contents of the utility model are not limited to the following examples.

[0023] As Figure 2 and Figure 3 shown, a homogenizing stirring equipment, unlike the prior art, has a holding piece 1 for holding liquid medicine, specifically, the holding piece 1 includes a vertically arranged holding cylinder 102, the bottom of the holding cylinder 102 is provided with a support foot 101 to enable the holding cylinder 102 to be stably placed, the top of the holding cylinder 102 is provided with a liquid inlet 103, the liquid inlet 103 can pour liquid medicine for storage, and then cooperate with a homogenizing assembly 2 arranged on the holding cylinder 102 to stir, to homogenize the liquid medicine, so as to maintain the quality stability and consistency of the liquid medicine by the staff, the homogenizing assembly 2 includes a drive motor 201 fixedly arranged at the center of the top of the holding cylinder 102, the drive motor 201 drives a drive shaft 202 penetrating through the top surface of the holding cylinder 102 and arranged in the holding cylinder 102, the drive shaft 202 is provided with a stirring fan 203, the stirring fan 203 can rotate at high speed with the drive shaft 202 driven by the drive motor 201, and then the stirring fan 203 will mix and stir the liquid medicine in the holding cylinder 102, to homogenize the liquid medicine. Specifically, the rotation of the stirring fan 203 mainly makes the liquid medicine produce macro flow through the pushing action of the blade, and then form a large range of liquid flow circulation, and through this stirring, the dissolution of solute in the liquid medicine can be accelerated, the heat transfer and mass exchange between each part of the liquid medicine are promoted, and the solid particles in the liquid medicine can also be prevented from settling at the bottom of the container.

[0024] The liquid inlet 103 is provided with an openable cover 104 covering the liquid inlet 103, and the openable cover 104 is hinged to the liquid inlet 103 corresponding to the containing cylinder 102, so as to close or open the containing cylinder 102 for the staff to close the containing cylinder 102 for stirring and open the containing cylinder 102 for pouring the liquid medicine, and the openable cover 104 is provided with two clamping handles 105 on the side away from the containing cylinder 102, so as to facilitate the staff to pull and rotate the openable cover 104 to open or close the liquid inlet 103, and the clamping handle 105 can be clamped with a driving motor 201 arranged on the top of the containing cylinder 102, so as to position and keep the openable cover 104 in the open state of the containing cylinder 102, thereby facilitating the staff to pour the liquid medicine to be homogenized into the containing cylinder 102 for homogenization treatment.

[0025] Unlike the prior art, the end of the drive shaft 202 away from the drive motor 201 is drivingly connected with the homogenizer 206, and the homogenizer 206 is connected with the three positioning columns 204 arranged on the inner wall of the top of the containing cylinder 102. The three positioning columns 204 can assist in maintaining the relative position of the homogenizer 206, so as to maintain the relative position of the homogenizer 206 during the rotation of the drive motor 201 driving the homogenizer 206, so that the homogenizer 206 stably homogenizes the liquid medicine. Specifically, the homogenizer 206 is a rotary cutting type homogenizer 206. When the drive motor 201 drives the drive shaft 202 to rotate, the drive shaft 202 drives the inner blade and inner rotor arranged in the homogenizer 206 to rotate. The rotation of the inner blade generates suction to suck the liquid medicine in the containing cylinder 102 into the homogenizer 206. Then the liquid medicine will flow to the inner blade with the tooth-shaped cutting knife arranged on the circumference of the inner blade through the outer cover with holes. The inner blade cuts the liquid medicine between the inner rotor and the outer cover multiple times at high speed to realize homogenization. That is, the homogenizer 206 will apply high shear force, high frequency vibration and cavitation effect to the liquid medicine during rotation, thereby enabling different phases of substances in the liquid medicine to be fully mixed, making the dispersed phase become smaller and more uniformly dispersed in the continuous phase, forming a stable emulsion or suspension, reducing the stratification and precipitation of the liquid medicine, and improving the stability and uniformity of the liquid medicine. The outer circumference of the three positioning columns 204 is provided with a flow guide cover 3. The flow guide cover 3 is funnel-shaped, the narrow end of the flow guide cover 3 covers the homogenizer 206, the bottom of the flow guide cover 3 is fixed to the bottom of the containing cylinder 102 through multiple support columns 4, the flared end of the flow guide cover 3 is arranged at the top of the containing cylinder 102, and the flow guide cover 3 corresponds to the liquid inlet 103 to allow the liquid medicine entering the containing cylinder 102 to first enter the flow guide cover 3, so that the flow guide cover 3 limits the solute in the liquid medicine, so that most of the solute in the liquid medicine is arranged close to the homogenizer 206 or the stirring fan 203, thereby improving the speed of the homogenizer 206 and the stirring fan 203 breaking the solute to some extent. When the drive motor 201 drives the drive shaft 202 to rotate, the stirring fan 203 and the homogenizer 206 rotate stably, most of the solute in the liquid medicine quickly contacts the homogenizer 206 and the stirring fan 203. When the homogenizer 206 and the stirring fan 203 continuously rotate, a negative pressure is generated at the corresponding position of the flow guide cover 3, thereby enabling the liquid medicine between the outer circumference of the flow guide cover 3 and the inside of the containing cylinder 102 to be sucked into the inside of the flow guide cover 3 from the bottom of the flow guide cover 3. After the liquid medicine is homogenized by the rotation of the homogenizer 206 and the stirring fan 203, the homogenized liquid medicine will pass through the screen holes uniformly arranged on the flow guide cover 3 to be discharged between the outer circumference of the flow guide cover 3 and the inner wall of the containing cylinder 102, so that the liquid medicine circulates into the inside of the flow guide cover 3 and is then discharged, thereby further improving the homogenization effect of the liquid medicine, and also maintaining the homogenization efficiency of the liquid medicine by cooperating with the initial restraining effect of the flow guide cover 3 on the solute in the liquid medicine.

[0026] Three positioning columns 204 are provided with turbulence strips 205, and the turbulence strips 205 are continuously arranged along the axial direction of the positioning columns 204. The plurality of turbulence strips 205 can disturb the turbulent flow generated when the homogenizer 206 and the stirring fan 203 drive the stirring rotation of the liquid medicine, thereby increasing the frequency of mutual collision and friction of the particles or droplets in the liquid medicine, and then the breaking speed of the larger particles or droplets in the liquid medicine is increased, and the homogenization effect of the liquid medicine is further improved. The rough layer 106 is arranged on the inner wall of the containing cylinder 102. The rough layer 106 can hinder and interfere with the liquid medicine flowing between the flow guide cover 3 and the inner wall of the containing cylinder 102 after passing through the screen hole, thereby destroying the laminar flow state of the liquid medicine and promoting the change of the liquid medicine to turbulent flow. The protruding part of the rough layer 106 can generate a shearing force on the liquid medicine close to the cylinder wall. The shearing force can further break the particles or droplets, reduce the size of the particles or droplets, and more uniformly distribute the particles or droplets in the liquid medicine to improve the homogenization degree of the liquid medicine.

[0027] In specific use, as shown in the figure, Figure 3 The opening and closing cover 104 is opened, and then the staff can pour the liquid medicine into the flow guide cover 3. As shown in the figure, Figure 2 The opening and closing cover 104 is closed, so that most of the solute in the liquid medicine is limited in the flow guide cover 3. Then the driving motor 201 is started to drive the stirring fan 203 and the homogenizer 206 to rotate through the driving shaft 202, finely crush the solute limited in the flow guide cover 3, and improve the efficiency of the solute uniformly distributed in the liquid medicine. At the same time, the liquid medicine between the flow guide cover 3 and the inner wall of the containing cylinder 102 enters the flow guide cover 3 and is discharged from the screen holes uniformly arranged on the flow guide cover 3 to form a circulation to further improve the homogenization efficiency and effect of the liquid medicine. During the circulation process, the turbulence strips 205 and the rough layer 106 are used to make the solute in the liquid medicine collide and press each other, thereby further improving the homogenization effect and efficiency of the liquid medicine. After a certain period of time, the opening and closing cover 104 can be opened by the clamping buckle 105 to pour out the homogenized liquid medicine for subsequent processing or packaging.

[0028] The specific embodiments of the utility model are described above. It should be understood that the utility model is not limited to the above specific embodiments, and those skilled in the art can make various modifications or changes within the scope of claims, which does not affect the essential content of the utility model.
