Description

Technical Field

[0001] This utility model relates to a liquid preparation device, specifically a liquid preparation device for quick replacement and maintenance, and belongs to the field of liquid preparation technology. Background Technology

[0002] Chemical drug manufacturing involves synthesizing active ingredients through chemical reactions, encompassing multiple steps of synthesis and purification. Liquid preparation, on the other hand, is the later stage of pharmaceutical manufacturing, where the active ingredient is mixed with excipients in a specific ratio to form a usable formulation. These two processes are inseparable in drug production: the former provides the core components, while the latter completes the dosage form preparation. Their seamless integration requires extremely high precision and cleanliness to ensure efficacy and safety.

[0003] Chinese Patent Publication No. CN222641852U discloses a chemical drug mixing and preparation device, which includes a pulverizing tank, a pulverizing motor, and pulverizing blades. This device facilitates the mixing of solid chemical drugs, enabling them to be quickly and easily pulverized into powder, resulting in more thorough reaction and mixing. By incorporating two sets of electric telescopic rods, two sets of flow regulating valves, a liquid delivery pipe, and a powder delivery pipe, the device allows for adjustment of the liquid or powder delivery pipe to a suitable height, enabling the solution or powder to slowly fall into the mixing tank and into other solutions, reducing splashing and ensuring more stable reaction and mixing.

[0004] Chemical drug preparation requires extremely high cleanliness, necessitating regular maintenance of the storage tank and preparation vessel to keep them clean. In the aforementioned patented technology, the storage tank and preparation vessel are connected together, making cleaning, maintenance, or replacement cumbersome. Therefore, a quick-change and maintenance preparation device is proposed here. Utility Model Content

[0023] Please see Figures 1-4 The present invention proposes the following implementation scheme: a quick-change and maintenance liquid preparation device, including a liquid storage tank 1 and a mixing tank 2. The liquid storage tank 1 includes a tank body 101 and a first pipe 103. The tank body 101 is used to store liquid and plays the role of containing liquid.

[0024] A connecting pipe 105 is installed on the top of the tank body 101. The first pipe 103 is connected to the matching tank 2 through the liquid delivery device 4. A support leg 102 is fixed at the bottom of the tank body 101. An inlet pipe 104 is fixed at the top of the tank body 101. A valve is installed on the inlet pipe 104.

[0025] Please refer to this carefully. Figure 1 and Figure 2 The mixing tank 2 includes a tank body 201, which is used for dispensing liquid. A support column 202 is fixed to the top of the tank body 201, and a motor 203 is fixed to the top of the support column 202. A stirring rod 204 is fixed to the output end of the motor 203. A valve 205 is installed at the bottom of the tank body 201. When the motor 203 is started, it can drive the stirring rod 204 to rotate.

[0026] The rotation of the stirring rod 204 can stir the liquid in the tank 201, thereby improving the uniformity of the liquid preparation. A valve is installed on the valve 205. The liquid delivery device 4 is installed on the support column 202. The liquid delivery device 4 can deliver the liquid in multiple tanks 101 to the inside of the tank 201. The liquid delivery device 4 includes components such as pipes and delivery pumps.

[0027] Please refer to this carefully. Figure 3 and Figure 4 It also includes a connecting component 3, which is disposed between the tank body 101 and the first pipeline 103. The connecting component 3 is also disposed between the liquid delivery device 4 and the matching tank 2. The connecting component 3 includes a bottom shell 301, a fixed sleeve 302 is slidably sleeved on the bottom shell 301, a sealing gasket 313 is fixed inside the fixed sleeve 302, a hose 303 is connected to the fixed sleeve 302, and a disassembly and assembly component is provided between the fixed sleeve 302 and the bottom shell 301.

[0028] The disassembly and assembly component includes a mounting hole 304, which is formed on a fixed sleeve 302. A sealing gasket 313 is fixed inside the fixed sleeve 302. An eccentric block 305 is rotatably connected inside the mounting hole 304. An arc-shaped plate 306 is provided on the eccentric block 305. The disassembly and assembly component also includes an eccentric annular groove 307, which slides in contact with the eccentric block 305.

[0029] An eccentric block 305 is provided with a guide block 308. The eccentric block 305, the arc plate 306, and the guide block 308 are integrally formed. A guide groove 309 is provided on the bottom shell 301. A limit plate 310 is fixed on the arc plate 306. A locking plate 312 is fixed on the limit plate 310.

The locking seat 311 is used to lock the locking plate 312, so as to realize the quick fixation of the limit plate 310.

[0030] Working principle: When maintenance is required on tank 101 or barrel 201, the arc plate 306 is moved, which will drive the eccentric block 305 to rotate. The eccentric block 305 will rotate in the eccentric annular groove 307 until it moves out of the eccentric annular groove 307. At this time, the fixing sleeve 302 is rotated, and the guide block 308 is driven to the position of the guide groove 309 through the fixing sleeve 302. Finally, the fixing sleeve 302 is removed from the bottom shell 301 to disassemble tank 101.

[0031] When installing the tank 101 or barrel 201 after maintenance, first align the guide block 308 with the guide groove 309, then insert the fixing sleeve 302 into the bottom shell 301, then rotate the fixing sleeve 302, and finally move the arc plate 306 so that the eccentric block 305 rotates in the eccentric annular groove 307. The eccentric block 305 will apply pressure to the bottom shell 301 through the eccentric annular groove 307, thereby making the sealing gasket 313 in the fixing sleeve 302 tightly press against the bottom shell 301, thus realizing the installation. This device can easily disassemble and assemble the tank 101 and barrel 201, improving the convenience of cleaning.
