Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical manufacturing technology, specifically to a piracetam injection filtration device. Background Technology

[0002] Piracetam injection is a commonly used neurological drug with extremely high production quality requirements, especially regarding the strict pharmacopoeia standards for controlling insoluble microparticles in the solution. In the final filtration process before filling, trace particles, fibers, or colloids that may be present in the solution must be removed to ensure the product's clarity, safety, and stability.

[0003] However, in existing filtration equipment, the filter element is usually statically fixed inside the filter cartridge during the filtration process. The liquid medicine passes through the filter layer vertically by its own gravity or system pressure. Due to the deep filtration characteristics of polypropylene meltblown filter element, particulate matter tends to accumulate rapidly on the surface and in the internal pores of the filter element, forming a dense filter cake layer. This leads to a sharp increase in filtration resistance, a significant decrease in flow rate, and an extended overall filtration cycle, affecting production efficiency. To address these issues, the inventors have proposed a piracetam injection filtration device to solve the above problems. Utility Model Content

[0004] To address the problem that particulate matter easily accumulates rapidly on the surface and in the internal pores of the filter element, leading to a sharp increase in filtration resistance and a significant decrease in flow rate, the purpose of this invention is to provide a piracetam injection filtration device.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a piracetam injection filtration device, comprising a filter box, a mounting frame slidably disposed inside the filter box, a mounting plate placed inside the mounting frame, a filter element installed inside the mounting plate, a U-shaped frame fixedly disposed on the top surface of the mounting frame, the U-shaped frame slidably inserted into the filter box, an ear plate fixedly disposed on the top surface of the filter box, a motor fixedly disposed on one side of the ear plate, a rotating shaft fixedly disposed at the output end of the motor, a cam fixedly sleeved on the outer surface of the rotating shaft, the cam being able to fit against the bottom surface of the U-shaped frame, sliders fixedly disposed on both sides of the mounting frame, the sliders slidably disposed inside the filter box, a sliding groove opened inside the filter box, the sliders slidably disposed in the sliding groove. First, the piracetam injection to be filtered enters the filter box. When the liquid flows through the filter element on the mounting plate, impurities and particulate matter are intercepted. Then, the motor is started, driving the rotating shaft and the cam on it to rotate. The rotating cam periodically abuts against and lifts the bottom surface of the U-shaped frame. Since the U-shaped frame is fixedly connected to the mounting bracket, and the mounting bracket is restricted to sliding vertically through the cooperation of the slider and the slide groove, the rotational motion of the cam is converted into the periodic up-and-down vibration of the mounting bracket and its internal filter element. This continuous, small-amplitude vibration can constantly disturb the surface of the filter element, making it difficult for the particles that have just begun to accumulate to adhere stably, thereby delaying or even destroying the formation of a dense filter cake layer. This allows the filter element to maintain a filtration capacity with low resistance close to its initial state for a longer period of time, thereby maintaining a high average filtration speed.

[0006] The filtered clean solution collects and discharges along the inclined platform. During normal operation (filtration or vibration), the pressure plate is pressed tightly against the top of the mounting plate by the torsion of the torsion spring, ensuring that it is firmly placed on the bracket and will not shift due to vibration. When the filter element needs to be replaced or cleaned, the operator can overcome the force of the torsion spring and rotate the pressure plate upward to release it from the pressure on the mounting plate. Then the mounting plate and the filter element can be removed vertically upward from the bracket of the mounting frame. The entire replacement process does not require disassembly of other complex parts, and the operation is simple and quick.

[0007] Preferably, a bracket is fixedly provided inside the mounting frame, the mounting plate is placed on the top of the bracket, a rotating rod is rotatably inserted inside the mounting frame, a pressure plate is fixedly sleeved on the outer surface of the rotating rod, the pressure plate is attached to the top surface of the mounting plate, a fixing groove is opened inside the mounting frame, the pressure plate is rotatably disposed in the fixing groove, a groove is opened inside the mounting frame, a torsion spring is fixedly provided in the groove, the other end of the torsion spring is fixedly disposed on the outer surface of the rotating rod, a frame is fixedly provided inside the filter box, the U-shaped frame slides through the frame, and a ramp is fixedly provided at the bottom end of the filter box.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. Through the periodic up-and-down vibration of the mounting frame and its internal filter element, this continuous, small-amplitude vibration can constantly disturb the surface of the filter element, making it difficult for the particles that have just begun to accumulate to adhere stably, thereby delaying or even destroying the formation of a dense filter cake layer. This allows the filter element to maintain a filtration capacity with low resistance close to its initial state for a longer period of time, thereby maintaining a high average filtration speed, a short overall filtration cycle, and improving production efficiency.

[0010] 2. When the filter element needs to be replaced or cleaned, the operator can overcome the force of the torsion spring and rotate the pressure plate upward to release it from the pressure on the mounting plate. Then the mounting plate and the filter element can be taken vertically upward from the bracket of the mounting frame. The entire replacement process does not require disassembling other complicated parts, and the operation is simple and quick. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1-6 As shown, this utility model provides a piracetam injection filtration device, including a filter box 1. A mounting frame 3 is slidably disposed within the filter box 1. A mounting plate 31 is placed within the mounting frame 3. A filter element 32 is installed within the mounting plate 31. A U-shaped frame 24 is fixedly disposed on the top surface of the mounting frame 3 and slidably inserted into the filter box 1. An ear plate 2 is fixedly disposed on the top surface of the filter box 1. A motor 21 is fixedly disposed on one side of the ear plate 2, and a rotating shaft 22 is fixedly disposed at the output end of the motor 21. A cam 23 is fixedly fitted on the outer surface of the rotating shaft 22. The cam 23 can fit against the bottom surface of the U-shaped frame 24. Slider 34 is fixedly provided on both sides of the mounting bracket 3. The slider 34 is slidably disposed in the filter box 1. A sliding groove 101 is provided in the filter box 1. The slider 34 is slidably disposed in the sliding groove 101. (The filter element 32 is a polypropylene meltblown filter element.) By starting the motor 21, the rotating shaft 22 and the cam 23 on it are driven to rotate. The rotating cam 23 periodically abuts against and lifts the bottom surface of the U-shaped frame 24. Since the U-shaped frame 24 is fixedly connected to the mounting bracket 3, and the mounting bracket 3 is restricted to sliding vertically through the cooperation of the slider 34 and the slide groove 101, the rotational motion of the cam 23 is converted into the periodic up-and-down vibration of the mounting bracket 3 and its internal filter element 32. This continuous, small-amplitude vibration can constantly disturb the surface of the filter element 32, making it difficult for the particles that have just begun to accumulate to adhere stably, thereby delaying or even destroying the formation of the dense filter cake layer. This allows the filter element 32 to maintain a filtration capacity with low resistance close to its initial state for a longer period of time, thereby maintaining a high average filtration speed, a short overall filtration cycle, and improved production efficiency.

[0021] The mounting frame 3 is fixedly provided with a bracket 33, and the mounting plate 31 is placed on the top of the bracket 33. A rotating rod 35 is rotatably inserted into the mounting frame 3, and a pressure plate 36 is fixedly sleeved on the outer surface of the rotating rod 35. The pressure plate 36 is attached to the top surface of the mounting plate 31. A fixing groove 302 is opened in the mounting frame 3, and the pressure plate 36 is rotatably disposed in the fixing groove 302. A groove 301 is opened in the mounting frame 3, and a torsion spring 37 is fixedly provided in the groove 301. The other end of the torsion spring 37 is fixedly disposed on the outer surface of the rotating rod 35. A frame 11 is fixedly provided in the filter box 1, and the U-shaped frame 24 slides through the frame 11. A ramp 12 is fixedly provided in the bottom end of the filter box 1.

[0022] By adopting the above technical solution, during normal operation (filtration or vibration), the pressure plate 36 is pressed tightly against the top of the mounting plate 31 under the torsion of the torsion spring 37, ensuring that it is stably placed on the bracket 33 and will not shift due to vibration. When the filter element 32 needs to be replaced or cleaned, the operator can overcome the force of the torsion spring 37 and rotate the pressure plate 36 upward to release it from the pressure on the mounting plate 31. Then the mounting plate 31 together with the filter element 32 can be vertically removed from the bracket 33 of the mounting frame 3. The entire replacement process does not require disassembling other complex parts, and the operation is simple and quick.

[0023] Working principle: First, the piracetam injection solution to be filtered enters the filter box 1. When the liquid flows through the filter element 32 on the mounting plate 31, impurities and particulate matter are trapped. Then, the motor 21 is started, driving the rotating shaft 22 and its cam 23 to rotate. The rotating cam 23 periodically abuts against and lifts the bottom surface of the U-shaped frame 24. Since the U-shaped frame 24 is fixedly connected to the mounting frame 3, and the mounting frame 3 is restricted to sliding vertically through the cooperation of the slider 34 and the slide groove 101, the rotational motion of the cam 23 is converted into the periodic up-and-down vibration of the mounting frame 3 and its internal filter element 32. This continuous, small-amplitude vibration can constantly disturb the surface of the filter element 32, making it difficult for the particles that have just begun to accumulate to adhere stably, thereby delaying or even destroying the formation of a dense filter cake layer. This allows the filter element 32 to maintain a filtration capacity with low resistance close to its initial state for a longer period of time, thereby maintaining a high average filtration speed.

[0024] The filtered clean liquid is collected and discharged along the inclined platform 12. During normal operation (filtration or vibration), the pressure plate 36 is pressed tightly against the top of the mounting plate 31 under the torsion of the torsion spring 37, ensuring that it is firmly placed on the bracket 33 and will not shift due to vibration. When the filter element 32 needs to be replaced or cleaned, the operator can overcome the force of the torsion spring 37 and rotate the pressure plate 36 upward to release it from the pressure on the mounting plate 31. Then the mounting plate 31 and the filter element 32 can be taken vertically upward from the bracket 33 of the mounting frame 3. The entire replacement process does not require disassembling other complex parts, and the operation is simple and quick.

The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
