[0002] Antibacterial liquid generally refers to liquid that inhibits bacterial growth. Commonly used antibacterial liquids in clinical practice include medical antibacterial disinfectants, medical skin and mucous membrane protectants, and other drugs, which can play a role in cleaning and sterilization. Antibacterial liquid is made by stirring and mixing a variety of raw materials, so stirring equipment is required, but the existing stirring equipment has a relatively simple structure and low raw material mixing efficiency, which needs to be improved.

[0003] The technical solution disclosed in the Chinese patent with authorization announcement number CN214182717U adopts a stirring pump and a structure in which gas emerges from below. It utilizes the physical property that the density of Chinese medicine powder after being wetted is not much different from that of the solution. The Chinese medicine powder rolls up and down in the solution driven by bubbles, thereby achieving full mixing with the solution and integrating the medicinal effect into the solution to improve the mixing efficiency of the raw materials.

[0004] However, the device still has some shortcomings: the device uses air to drive the mixing of raw materials, and for some raw materials with obvious volatility, their properties are very easy to change. Therefore, the device has limitations on the composition of the antibacterial liquid, and the device lacks active filtering and screening functions during the discharging process.

[0011] And a driving component B, the driving component B is connected to the sealing cover and drives the sealing column. The driving component B drives the sealing column to rotate in a working state to achieve the blocking or unloading of the discharge port.

[0012] Preferably, a base is provided at the bottom of the mixing barrel, the base comprises a support rod and a bottom plate, the support rod connects the bottom plate and the mixing barrel, and the feed discharge pipe is located above the bottom plate of the base.

[0013] Preferably, the inner cavity of the mixing barrel is a chamber with an arc-shaped cross-section, and the discharge port is located at the lowest point of the inner cavity of the mixing barrel.

[0014] Preferably, the driving assembly A comprises a motor A, and an output end of the motor A is connected to an end of the rotating shaft.

[0027] like Figure 1-Figure 4 As shown, a raw material mixing device proposed by the utility model includes a mixing barrel 2, a rotating shaft 7, a driving assembly A, a sealing cover 11, a sealing column 13 and a driving assembly B. The mixing barrel 2 is provided with a feed port 101 and a discharge port 102 connected to the interior thereof, and the feed port 101 is connected to the feed hopper 3. The inner cavity of the mixing barrel 2 is a chamber with an arc-shaped cross section, and the discharge port 102 is located at the lowest point of the inner cavity of the mixing barrel 2. The feed hopper 3 is provided with a bucket cover 4 for sealing its opening, and the bucket cover 4 is rotatably connected to the feed hopper 3, and the feed hopper 3 is provided with a locking member for locking the bucket cover 4. The locking member includes a buckle 5 and a locking hook, the buckle 5 is connected to the feed hopper 3, the locking hook is connected to the bucket cover 4, and the buckle 5 cooperates with the locking hook. The rotating shaft 7 is located in the inner cavity of the mixing barrel 2 and is rotatably connected to both side end covers of the mixing barrel 2, and the rotating shaft 7 is provided with a stirring paddle 8 that is slidably connected to the inner wall of the mixing barrel 2. The driving component A includes but is not limited to the motor A10, which is connected to the mixing barrel 2, and the output end of the motor A10 is connected to the end of the rotating shaft 7. The sealing cover 11 is connected to the mixing barrel 2 and covers the outside of the discharge port 102, and the sealing cover 11 is connected to the feeding pipe 12. The bottom of the mixing barrel 2 is provided with a base 1, and the base 1 includes a support rod and a bottom plate, and the support rod connects the bottom plate and the mixing barrel 2, and the feeding pipe 12 is located above the bottom plate of the base 1. The sealing column 13 is located in the sealing cover 11 and is rotatably connected to the inner wall thereof. The sealing column 13 is provided with a sealing surface 131 for blocking the discharge port 102, and the sealing column 13 is provided with a through hole 132 connected to the discharge port 102, and a filter screen 15 is provided in the through hole 132. The driving component B is connected to the sealing cover 11 and drives the sealing column 13. The driving component B includes but is not limited to the motor B14, and the output end of the motor B14 is connected to the end of the sealing column 13. The motor B14 drives the sealing column 13 to rotate in a working state to achieve the blocking or discharge of the discharge port 102 .

[0028] In this embodiment, first, start the motor B14, which drives the sealing column 13 to rotate until the sealing surface 131 fits with the discharge port 102, thereby closing the discharge port 102. Then, open the bucket cover 4 to add the raw materials into the mixing barrel 2. Then, close the bucket cover 4, start the motor A10, and drive the rotating shaft 7 to rotate. The rotating shaft 7 drives the stirring paddle 8 to rotate. During the rotation, the stirring paddle 8 drives the lower layer of material in the mixing barrel 2 to mix with the upper layer of material, thereby improving the raw material mixing efficiency and reducing the energy consumption of the equipment. After the raw materials are mixed, the motor B14 is started, and the motor B14 drives the sealing column 13 to rotate, so that the through hole 132 is connected with the discharge port, and the antibacterial agent in the mixing barrel 2 is discharged along the discharge port 102, the through hole 132 and the discharge pipe 12. During the discharge process, the undissolved impurities in the antibacterial agent are blocked by the filter screen 15.

The motor B14 drives the sealing column 13 to rotate 180 degrees, so that the through hole 132 is inverted. At this time, the impurities in the space above the filter screen 15 are discharged along the discharge pipe 12. In order to ensure clean discharge, the above operation can be repeated several times.

At this time, two spiral plates 9 with opposite rotation directions are installed. The spiral plates 9 rotate with the rotating shaft 7. The spiral plates 9 drive the materials on both sides to approach the middle during the rotation, thereby promoting the mixing of the raw materials in the inner cavity of the entire mixing barrel 2, and further improving the mixing efficiency.

[0032] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
