Description

Technical Field

[0001] The utility model belongs to the field of hyaluronic acid dressing technology, in particular to a mixing device for producing hyaluronic acid dressing. Background Art

[0002] Hyaluronic acid has unique physical and chemical properties and physiological functions, and has been widely used in medicine and biomaterials. Hyaluronic acid generates heat during the mixing process, and these factors can cause dirt and bacteria to accumulate inside the equipment when used for a long time. However, the relatively sealed design makes it very difficult to clean and maintain the mixing barrel, which requires more time and cost. At the same time, some mixing devices are not equipped with filtering devices, which can easily cause particulate impurities in the hyaluronic acid, reducing the quality of hyaluronic acid production. If the raw materials contain impurities or dust, these impurities may be directly mixed into the hyaluronic acid dressing, affecting product quality.

[0003] The publication number CN 114042400 A discloses a mixing device for producing hyaluronic acid dressings, comprising: a machine base and a mixing barrel arranged on the machine base, a filtering mechanism being arranged below the mixing barrel, a feeding unit being arranged on the top of the mixing barrel, a motor mounting frame being fixed on the top of the mixing barrel, a stirring motor being installed on the motor mounting frame, an output shaft of the stirring motor being connected to a stirring shaft extending into the mixing barrel, a rod body of the stirring shaft being provided with stirring paddles evenly distributed, a transmission assembly being connected to the stirring shaft, and the transmission assembly being used to drive the filtering mechanism, the device can filter out incompletely reacted solid particles, ensure the quality of hyaluronic acid, and the transmission shaft rotates when the stirring shaft stirs, so that the filter plate can move up and down, thereby preventing the filter plate from being blocked and ensuring smooth filtering.

[0004] However, since the mixing barrel of the above-mentioned device is a relatively sealed structure, the mixing barrel cannot be opened, and it becomes very difficult to clean and maintain the mixing barrel, which requires more time and cost. Once a failure occurs or parts need to be replaced, maintenance personnel need to disassemble the entire device to repair or replace parts, which will increase the maintenance cost and time of the equipment. At the same time, the filtering mechanism of the device is below the mixing barrel, and the upper side of the filtering device is an open design. Due to its openness, the non-closed filtering device is more susceptible to external pollutants, such as dust, bacteria, etc. This may affect the quality and safety of hyaluronic acid dressings, and the filtering mechanism is relatively complex. The filtering device needs to be cleaned and maintained regularly, which increases the cleaning difficulty and cost of the device. Therefore, in order to solve the above problems, a mixing device for the production of hyaluronic acid dressings is proposed. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a mixing device for producing hyaluronic acid dressings which has high practicability, can be simply operated and has a relatively simple structure.

[0006] In order to solve the above technical problems, the utility model provides a mixing device for the production of hyaluronic acid dressings, comprising: a mixing barrel placed above a bottom plate for storing dressings, a support frame fixed above the bottom plate, and a stirring mechanism for mixing the dressings is installed on the support frame, the stirring mechanism is inserted in a stirring bin inside the mixing barrel, and a filter mechanism for easy replacement is fixed on the mixing bin, a discharge port is provided at the bottom of the side wall of the mixing bin, and a barrel cover is clamped on the top of the mixing bin, a feeding hopper for convenient entry of the dressings is inserted on the barrel cover, and a movable groove for convenient removal of the barrel cover is provided on the barrel cover.

[0007] As a further solution of the present invention, the bottom of the mixing chamber is a funnel-shaped structure, and the discharge port is communicated with the inner cavity of the mixing chamber, which can help to collect the dressings at the bottom and reduce the residue in the mixing chamber.

[0008] As a further solution of the utility model, the stirring mechanism includes a driving motor, a rotating rod and stirring blades, and a group of the stirring blades is composed of three stirring blades with the same spacing angle.

[0009] As a further solution of the utility model, two sets of stirring blades are fixed at the bottom position of the rotating rod, and the part of the rotating rod with the stirring blades is inserted into the interior of the stirring chamber to mix the dressing inside the stirring chamber.

[0010] As a further solution of the utility model, the barrel cover is provided with a movable groove at a position corresponding to the stirring mechanism, and the width of the movable groove is greater than the diameter of the rotating rod, so that the barrel cover is easy to take, thereby facilitating cleaning and maintenance.

[0011] As a further solution of the utility model, the filtering mechanism includes handles, a filter plate and a fixing block, two sets of handles are fixed above the filter plate, and the filter plate and the mixing chamber have the same radius, which facilitates moving and taking the filter plate.

[0012] As a further solution of the utility model, the four groups of fixed blocks are cross-fixed on the inner wall of the mixing chamber, and the filter plate is fixed at a height by abutting against the fixed blocks. The filter plate of the filter mechanism can be quickly disassembled and replaced with a new one. The convenient disassembly and replacement function makes maintenance easier.

[0015] 2. The utility model is designed with a filtering mechanism in the mixing chamber, which can effectively remove impurities in the mixture and ensure the purity and quality of the hyaluronic acid dressing. When the filtering mechanism is blocked or the efficiency decreases due to long-term use, the filter plate of the filtering mechanism can be quickly disassembled and replaced with a new one. The convenient disassembly and replacement function makes maintenance simpler, helps to maintain the filtering effect, reduces downtime, and improves overall production efficiency, thereby ensuring product quality.
