DETAILED DESCRIPTION

[0014] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. The same parts are represented by the same figure marks. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom" and "top", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0015] like Figure 1 and Figure 2 As shown, a liquid medicine unloading device comprises a buffer tank 1, a unloading pump 2 and a medicine storage tank 3. A feed pipe 4 is provided on one side of the buffer tank 1, one end of the feed pipe 4 is connected to an external medicine tank, and the other end of the feed pipe 4 is connected to the buffer tank 1. A feed valve 5 is provided on the feed pipe 4. After the feed valve 5 is opened, the medicine in the medicine tank enters the buffer tank 1 through the feed pipe 4.

[0016] A connecting pipe 6 is provided on the other side of the buffer tank 1, and the other end of the connecting pipe 6 is connected to the feed end of the discharge pump 2. The suction force generated after the discharge pump 2 is started can suck out the medicine in the medicine tank, so that it can enter the buffer tank 1 along the feed pipe 4. The medicine in the buffer tank 1 will also move along the connecting pipe 6 to the position of the discharge pump 2. The discharge end of the discharge pump 2 is connected to a discharge pipe 7, and the medicine passing through the discharge pump 2 will flow into the discharge pipe 7. The other end of the discharge pipe 7 is connected to the medicine storage tank 3. The discharge pump 2 generates thrust in the discharge pipe 7 to send the medicine in the discharge pipe 7 into the medicine storage tank 3 to complete the discharge.

[0017] An exhaust pipe 8 is also provided on the buffer tank 1, and the other end of the exhaust pipe 8 is connected to the upper end of the medicine storage tank 3. An exhaust valve 9 is provided on the exhaust pipe 8. After the exhaust valve 9 is opened, the gas generated by the volatilization of the agent can be transported to the medicine storage tank 3 through the exhaust pipe 8 to prevent the gas from polluting the environment.

[0018] The buffer tank 1 includes an outer tank body 10, an inner tank body 11 and an interlayer 12. Both the outer layer and the inner layer are made of materials that will not react with commonly used medicines. The specific materials can be selected according to the types of commonly used medicines. The interlayer 12 is located between the outer tank body 10 and the inner tank body 11. The interlayer 12 is made of a heat-insulating material, which can reduce the degree to which the medicine is affected by the external temperature. The interlayer 12 is fixedly connected to the outer tank body 10, and the inner tank body 11 and the interlayer 12 are detachably connected. Since the inner tank body 11 needs to be in direct contact with the medicine, the inner tank body 11 and the interlayer 12 are designed to be detachably connected. This allows the outer tank body 10 and the interlayer 12 to be manufactured using a unified device, while the inner tank body 11 may require different equipment depending on the material selection. Such a design can reduce the production cost of the outer tank body 10 and the interlayer 12.

[0019] A tank door is provided on one side of the outer tank body 10, one side of the tank door is hingedly connected to the outer tank body 10, and the other side of the tank door is snap-connected to the outer tank body 10. After the tank door is opened, the inner tank body 11 can be taken out from the tank door, or the inner tank body 11 can be installed from the tank door to the inner side of the interlayer 12. A plurality of positioning grooves can be provided on the inner side wall of the interlayer 12, and a plurality of positioning blocks can be provided on the outer wall of the inner tank body 11. The positioning blocks are slidably connected to the positioning grooves, which can help locate the position between the inner tank body 11 and the interlayer 12.

[0020] The outer tank body 10 and the interlayer 12 are each provided with three connection holes, and each of the three connection holes is provided with a connection pipe 14, and two connection pipes 14 are respectively used to connect the exhaust pipe 8, the connecting pipe 6 and the feed pipe 4. The inner tank body 11 is also provided with three connecting holes, and the diameter of the connecting holes is the same as that of the connecting holes. After the inner tank body 11 is installed inside the interlayer 12, the three connecting holes correspond to the positions of the three connection holes.

[0021] The connecting tube 14 is slidably connected to the connecting hole. When the inner shell needs to be installed or removed, the connecting tube 14 can be pulled so that the end of the connecting tube 14 located on the inner side of the interlayer 12 moves into the interlayer 12. At this time, the inner shell can be placed in or removed from the inner side of the interlayer 12. To illustrate the installation of the inner shell, first move one end of the connecting tube 14 to the inside of the interlayer 12, that is, into the connecting hole on the interlayer 12, and then put the inner shell from the tank door into the inner side of the interlayer 12. The positions of the three connecting holes on the inner shell correspond to the three connecting holes. Move the two connecting tubes 14 so that one end of the two connecting tubes 14 is respectively inserted into the exhaust hole or the connecting hole, so that the inner tank body 11 can communicate with the outside through the two connecting tubes 14.

[0022] In order to ensure the sealing of the two connecting holes, a sealing rubber block 13 is provided on the connecting tube 14. The sealing rubber block 13 is made of elastic material, such as silicone. When the connecting tube 14 moves outward, the sealing rubber block 13 will be driven to move out of the connecting hole; after the inner shell is installed to the inner side of the interlayer 12, the sealing rubber block 13 will also be inserted into the connecting hole to seal the connecting hole. In order to increase the sealing performance of the sealing rubber block 13, the sealing rubber block 13 is made into a truncated cone shape, the diameter of one end of the sealing rubber block 13 is smaller than the diameter of the connecting hole, and the diameter of the other end is larger than the diameter of the connecting hole, and the end of the sealing rubber block 13 with a smaller diameter is inserted into the connecting hole.

[0023] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
