[0002] Injectable solutions are solutions or suspensions prepared under sterile conditions. They are administered directly into human tissues, blood, or cavities via injection. They are characterized by rapid onset of action and high bioavailability, and are suitable for emergency situations, situations where oral administration is not possible, or situations where drug stability is poor. Impurities may be generated during the production process of injectable solutions, and a filtration structure is generally required to filter out these internal impurities.
[0003] In the production of injectable solutions, ensuring product purity is crucial. Traditional filtration systems can typically only remove large particulate impurities, while their effectiveness in removing small particles or dissolved substances is limited. Furthermore, current technologies lack multi-stage filtration and quick disassembly or cleaning of the filtration structure, thus reducing the effectiveness of the equipment.
[0004] Therefore, a multi-stage impurity filtration mechanism for injection production is proposed here. Utility Model Content

The interior of each arc-shaped gate is in contact with the outer surface of the stainless steel filter screen, the outer surface of the coarse sand layer, the outer surface of the fine filter layer, and the outer surface of the activated carbon layer.

[0011] This utility model provides a multi-stage impurity filtration mechanism for injection solution production, which has the following beneficial effects:
[0012] 1. The multi-stage impurity filtration mechanism for injection production uses a vibration filtration mechanism to separate impurities present in the injection solution. An adjustable eccentric block is installed at each end of the rotor shaft of the vibration motor. The centrifugal force generated by the high-speed rotation of the shaft and the eccentric block is used to generate the excitation force. Under the buffering effect of the hydraulic damper, the excitation force drives the injection solution in the preliminary filter screen and filter frame to be screened, thereby improving the filtration effect of the injection solution.
[0013] 2. The multi-stage impurity filtration mechanism for this injection solution production can perform secondary separation of impurities in the injection solution through screening and separation filtration. The hydrocyclone generates centrifugal force, which enables efficient separation of the injection solution. After separation, the injection solution undergoes fine filtration through the stainless steel filter screen, coarse sand layer, fine filter layer, and activated carbon layer, thereby improving the filtration effect.

[0028] Please refer to this carefully. Figure 2 The filter box 1 is equipped with a storage cylinder 11 inside. The bottom surface of the storage cylinder 11 is in contact with the inner bottom wall of the filter box 1, which can recover the injection liquid after filtration by the device.
[0029] Please refer to this carefully. Figure 2The filter box 1 is equipped with a storage box 9 inside. The bottom surface of the storage box 9 is in contact with the inner bottom wall of the filter box 1. The impurities separated by the hydrocyclone 301 can be recovered through the storage box 9.
[0030] Please refer to this carefully. Figure 1 The outer surface of the controller body 6 is connected to a fixing frame 7. The back of the fixing frame 7 is fixedly connected to the front of the movable door 5. The fixing frame 7 can fix the controller body 6 and prevent it from falling off during use. The controller consists of two parts: hardware and software. The hardware mainly includes a central processing unit (CPU) for calculation, input / output (I / O) interfaces for connecting sensors and actuators, memory for storing programs and data, as well as power supply and communication modules. The software includes control algorithm programs, real-time operating systems such as RTOS, and human-machine interfaces, which together ensure accurate and efficient system control. It is widely used in industrial automation, smart homes, automotive electronics, and other fields. The controller is a core device that regulates system operation by processing input signals in real time and generating control commands. Its working principle can be summarized as follows: First, it collects signals from sensors or external inputs such as temperature and speed, and compares them with preset target values to calculate the deviation. Then, it uses built-in algorithms such as PID control and logical judgment to analyze the deviation and generate adjustment commands. Finally, it drives actuators such as motors and valves through the output interface to adjust the system state. At the same time, it continuously monitors the effect through closed-loop feedback to achieve dynamic stability. The controller can control the electrical components of this technical solution.
[0031] In use, the operator first connects the hydrocyclone 301, controller body 6, hydraulic damper 204, and vibration motor 208 to the power supply. The operator then injects the injection solution into the filter frame 201. Next, the operator selects a suitable preliminary filter screen 205 according to the initial screening requirements of the injection solution. Utilizing the sliding relationship between the preliminary filter screen 205 and the filter frame 206, the preliminary filter screen 205 is slid into the interior of the filter frame 206. Then, the protective door 202 is sealed to the filter frame 201 using the movable relationship between the protective door 202 and the filter frame 201. The operator then uses the controller body 6 to control the vibration motor 208. The vibration motor 208 has adjustable eccentric blocks installed at both ends of the rotor shaft. The centrifugal force generated by the high-speed rotation of the shaft and eccentric blocks generates the excitation force. Under the action of the hydraulic damper 204, the excitation force drives the preliminary filter screen 205 and the injection solution containing impurities within the preliminary filter screen 205 to continuously vibrate and separate. The impurities in the injection solution are initially separated. On the surface of the preliminary filter screen 205, the pre-filtered injection solution enters the interior of the hydrocyclone 301 through the injection shell 207. Then, the controller body 6 controls the hydrocyclone 301 to work. The operation of the hydrocyclone 301 generates centrifugal force, and the injection solution and its internal impurities are separated under the action of centrifugal force. After separation, the heavier solid impurities fall into the interior of the collection box 9 through the bottom of the hydrocyclone 301. The injection solution with smaller particles and mixed with other impurities enters the interior of the filter cylinder 305 through the transport pipe 302. Then, it passes through the stainless steel filter screen 307, the coarse sand layer 308, the fine filter layer 309, and the activated carbon layer 310 in sequence. Finally, it is discharged through the discharge port 306 and falls into the interior of the collection cylinder 11. Through the vibration filter mechanism 2 and the screening and separation filter mechanism 3 of this device, the injection solution is filtered and separated multiple times, thereby improving the filtration and separation effect of the injection solution. At the same time, during the separation and filtration process of the injection solution, the filter structure can be cleaned and replaced well, thereby improving the use effect of the device.
