[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. The scope of protection of the present invention is not limited by the embodiments.

[0024] like Figure 1 - Figure 3As shown, the utility model provides an embodiment: a drug concentration device, including a concentration tank 1, which serves as the main structure of the entire device and provides a closed space for the drug concentration process. A tank cover 2 is provided on the top of the concentration tank 1 to close the top opening of the concentration tank 1 to prevent the drug from splashing or being contaminated by the outside world during the concentration process. A hydraulic cylinder is provided on the rear side of the concentration tank 1 to control the opening and closing of the tank cover 2, which is convenient for inspection and cleaning of the interior of the concentration tank 1. The front side of the hydraulic cylinder output shaft is at the top of the tank cover 2. A drive motor 3 is provided on the top of the tank cover 2 to provide a power source for the stirring assembly and drive the various components in the stirring assembly to rotate, thereby stirring the medicine inside the concentration tank 1 and promoting uniform mixing and concentration of the medicine. This technology is existing technology, so it will not be described in detail.

[0025] Furthermore, a limiting component is provided on the inner wall of the tank cover 2, and a filter plate 5 is provided on the inner side of the limiting component, which is installed on the inner side of the mounting seat 41 and is fixed by a limiting block 42. During the drug concentration process, the filter plate 5 plays a role in filtering impurities. This technology is existing technology, so it is not described in detail. A drain pipe is provided on the lower side of the right end of the concentration tank 1 for discharging the concentrated medicine liquid. An air inlet pipe is provided on the upper side of the drain pipe of the concentration tank 1 for conveying hot steam to the concentration tank 1 to heat the medicine liquid. An air outlet pipe is provided on the top of the tank cover 2 for outputting the hot air in the concentration tank 1 and balancing the air pressure in the concentration tank 1. A stirring component is provided on the inner wall of the concentration tank 1. The stirring component includes a support seat 31, which provides an installation and support position for the bevel gear. The right side of the support seat 31 is fixedly connected to the inner side of the tank cover 2, and the left inner wall of the support seat 31 is rotatably connected to the bevel gear 2 33, which transmits the power of the drive motor 3 to the bevel gear 3 34 through the bevel gear 1 32.

[0026] like Figure 1 and Figure 3 As shown, bevel gear three 34 is engaged with the left side of bevel gear two 33, and rotates under the drive of bevel gear two 33, driving stirring rod one 36 to rotate in the opposite direction to perform stirring work. A stirring rod one 36 is fixedly installed on the outer side of the bottom end of bevel gear three 34 by bolts to stir the medicine inside the concentration tank 1, and cooperates with stirring rod two 37 to improve the stirring effect. At the same time, the stirring rod one 36 can be quickly replaced and installed through bolt fixation. The bottom end of the output shaft of the drive motor 3 is fixedly connected to a connecting rod 35, which rotates under the drive of the drive motor 3, driving stirring rod two 37 and bevel gear one 32 to rotate. The outer side of the connecting rod 35 is fixedly connected to bevel gear one 32, and the outer side of bevel gear one 32 is engaged with the upper left side of bevel gear two 33.

[0027] Furthermore, the lower side of the connecting rod 35 is rotatably connected to the inner wall of the bevel gear three 34, and the outer side of the bottom end of the connecting rod 35 is fixed with a stirring rod two 37 by bolts. The connecting rod 35 is driven to rotate to stir the medicine inside the concentration tank 1, and cooperates with the stirring rod one 36 to improve the stirring effect. The stirring rod two 37 can be quickly replaced and installed by bolt fixing. The bottom end of the stirring rod one 36 and the top end of the stirring rod two 37 are obliquely provided with vertical plates. The setting of the vertical plates can enhance the intensity and uniformity of the stirring.

[0028] like Figure 2 and Figure 4 The filter plate 5 is fixed to the inner wall of the concentration tank 1 by cooperating with the limiting groove 46 on the outer side of the filter plate 5. The right side of the limiting block 42 is elastically connected to the mounting seat 41 by a compression spring 43. The elastic force of the compression spring 43 keeps the limiting block 42 in the limiting groove 46 to prevent the filter plate 5 from loosening.

[0029] Furthermore, a baffle 45 is fixedly connected to the bottom end of the limit block 42, and a sealing ring is provided on the outside of the baffle 45 and the limit block 42 to prevent the liquid from entering the inside of the mounting seat 41. The baffle 45 is slidably connected to the inner wall of the mounting seat 41, and a pull plate 44 is fixedly connected to the bottom end of the baffle 45, which is convenient for the operator to manually pull the pull plate 44 to drive the limit block 42 to move, thereby releasing the limit on the filter plate 5. The pull plate 44 is slidably connected to the inner wall of the mounting seat 41, and the outer side of the filter plate 5 is plugged into the inner wall of the mounting seat 41. A limiting groove 46 is provided on the outside of the filter plate 5, and there are multiple groups of them to increase the limit block 42 The matching points with the limit groove 46 improve the stability of the filter plate 5 in the mounting seat 41, ensuring that the filter plate 5 will not shake or shift during operation. The outer side of the limit block 42 slides on the inner wall of the limit groove 46, and the upper left side of the limit block 42 is set as an inclined surface. When installing the filter plate 5, you only need to insert the filter plate 5 into the mounting seat 41. The edge of the filter plate 5 will contact the inclined surface of the limit block 42 and push the limit block 42 to move to the right. When the filter plate 5 is fully inserted, the limit block 42 moves to the left under the action of the compression spring 43 and inserts into the limit groove 46 to achieve automatic limiting.

[0030] The working principle of the present utility model is as follows: when in use, during the drug concentration process, the drug liquid is first injected into the concentration tank 1, the hydraulic cylinder is started, and the tank cover 2 is pushed to close the concentration tank 1. At this time, the drive motor 3 is started, driving the connecting rod 35, the stirring rod 2 37 and the bevel gear 1 32 to rotate, and the bevel gear 1 32 is engaged with the bevel gear 2 33 to transmit power to the bevel gear 2 33. The bevel gear 2 33 is engaged with the bevel gear 3 34 to drive the stirring rod 1 36 to rotate in the opposite direction, stirring the medicine inside the concentration tank 1, improving the stirring effect, and enhancing the intensity and uniformity of the stirring by the inclined vertical plate.

[0031] During the concentration process, the air inlet pipe transports hot steam to the concentration tank 1 to heat the drug liquid. The water in the drug liquid evaporates to form hot gas, which is output through the air outlet pipe at the top of the tank cover 2 to balance the air pressure in the concentration tank 1. During the drug concentration process, the filter plate 5 plays a role in filtering impurities.

[0032] When the filter plate 5 needs to be maintained and disassembled, the mounting seat 41 is removed from the inner wall of the concentration tank 1 by pulling the pull rod on the upper side of the mounting seat 41. The operator manually pulls the pull plate 44, and the pull plate 44 drives the baffle 45 and the limit block 42 to move. The limit block 42 slides out of the limit groove 46 on the outside of the filter plate 5, releasing the limit on the filter plate 5. At this time, the filter plate 5 can be taken out of the mounting seat 41, and the disassembly of the filter plate 5 is completed.

[0033] When installing the filter plate 5, it is only necessary to insert the filter plate 5 into the mounting seat 41. The edge of the filter plate 5 will contact the inclined surface of the upper left side of the limit block 42 and push the limit block 42 to move to the right. When the filter plate 5 is fully inserted, the limit block 42 moves under the action of the compression spring 43 and is inserted into the limit groove 46 opened on the outside of the filter plate 5 to achieve automatic limiting.
