Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical filter technology, and in particular to an energy-saving defoaming pharmaceutical filter. Background Technology

[0002] A pharmaceutical filter is a device specifically designed for filtering fluids such as pharmaceutical solutions and solvents in the pharmaceutical industry. Its core function is to remove impurities, particles, microorganisms, and other contaminants from the fluid, ensuring that the purity, safety, and quality of the pharmaceutical solution meet pharmaceutical production standards.

[0003] However, in existing technologies, the flow of the drug solution or chemical reactions easily generate foam. This foam adheres to the surface of the filter element or is suspended in the drug solution, forming a physical barrier that hinders the normal passage of the drug solution through the filter element pores. This leads to a significant decrease in filtration speed and a longer filtration cycle. At the same time, the foam occupies the filtration space, and some of the drug solution is trapped in the foam and cannot be discharged smoothly, resulting in waste of the drug solution. This is especially true for high-value drug solutions, where the economic loss is more significant. Existing filtration equipment mostly uses mechanical stirring, vacuum suction, or the addition of chemical defoamers to remove foam. Mechanical stirring and vacuum suction rely on motors, vacuum pumps, and other equipment to drive the process, which not only increases equipment costs and energy consumption but also requires a complex control system. This makes operation cumbersome and maintenance costs high. The use of chemical defoamers may introduce impurities, affecting the purity and quality of the drug solution, which does not meet the strict requirements of pharmaceutical filtration. Utility Model Content

[0004] The purpose of this invention is to solve the problems of foam generated in the medicine solution, which easily leads to a decrease in filtration efficiency and waste of medicine solution. Existing filtration equipment often requires additional energy to drive the defoaming device, resulting in high energy consumption and complicated operation. Therefore, an energy-saving defoaming pharmaceutical filter is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an energy-saving defoaming pharmaceutical filter, comprising a filter cylinder, a filter element disposed inside the filter cylinder, a positioning frame snapped onto the outer wall of the filter element, the bottom of the positioning frame being bolted to the filter cylinder, a top cover being slidably connected to the top of the filter cylinder, and a foam elimination mechanism being fixedly installed inside the top cover, the foam elimination mechanism comprising a vertical rod, a pressing plate and a sponge, the vertical rod being fixedly connected to the upper surface of the pressing plate, the sponge being fixedly installed on the lower surface of the pressing plate, and the pressing plate being located between the top cover and the positioning frame.

[0006] Preferably, a limiting tube is fixedly installed at the center of the top cover, and the vertical rod is located inside the limiting tube.

[0007] Preferably, a cylinder is fixedly installed on the outer wall of the vertical rod, the shape of the cylinder is adapted to the limiting tube, and the cylinder is located above the limiting tube.

[0008] Preferably, a tension spring is fixedly installed on the upper surface of the inner side of the cylinder, and one end of the tension spring is fixedly connected to the upper surface of the top cover.

[0009] Preferably, a feed pipe is connected to one side of the top of the filter cylinder, and a discharge pipe is connected to the bottom of the filter cylinder.

[0010] Preferably, the positioning frame has permeation holes at its edge.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by pressing down the vertical rod, it slides within the limiting tube, causing the pressing plate and the sponge fixed to its lower surface to move downwards until the sponge contacts the foam on the upper surface of the positioning frame. Upon contact, the sponge uses its own structure to crush the foam, and the liquid is absorbed by the sponge after the foam breaks. Subsequently, the pressing plate continues to press down, applying pressure to the sponge and squeezing out the liquid absorbed by the sponge, allowing the liquid to return to the filtration system, thus completing the defoaming and liquid recovery process. This reduces the problem of decreased filtration efficiency or loss of filtration solution caused by the presence of foam, and has good practicality and economy.

[0013] 2. In this utility model, the cylinder and the limiting tube are matched and a tension spring is used to ensure the stable lifting and lowering of the vertical rod, so that the defoaming operation is continuous and precise. The automatic reset function of the tension spring reduces the intensity of manual operation and improves the convenience of use. The setting of the permeation hole ensures the flow path of the medicine and does not affect the filtration efficiency. The overall structure achieves energy-saving defoaming through mechanical linkage and avoids energy consumption. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides an energy-saving defoaming pharmaceutical filter, including a filter cylinder 1, a filter element 7 inside the filter cylinder 1, a positioning frame 6 snapped onto the outer wall of the filter element 7, the bottom of the positioning frame 6 being bolted to the filter cylinder 1, a top cover 4 being slidably connected to the top of the filter cylinder 1, and a foam elimination mechanism 5 being fixedly installed inside the top cover 4. The foam elimination mechanism 5 includes a vertical rod 52, a pressing plate 55, and a sponge 54. The vertical rod 52 is fixedly connected to the upper surface of the pressing plate 55, the sponge 54 is fixedly installed on the lower surface of the pressing plate 55, the pressing plate 55 is located between the top cover 4 and the positioning frame 6, a limiting tube 51 is fixedly installed at the center of the top cover 4, and the vertical rod 52 is located inside the limiting tube 51.

[0022] The specific setup and function of this embodiment are described in detail below. By pressing down the vertical rod 52, it slides within the limiting tube 51, causing the pressing plate 55 and the sponge 54 fixed to its lower surface to move downwards until the sponge 54 contacts the foam on the upper surface of the positioning frame 6. Upon contact, the sponge 54 uses its own structure to burst the foam, and the liquid is absorbed by the sponge 54 after the foam bursts. Subsequently, the pressing plate 55 continues to press down, applying pressure to the sponge 54 and squeezing out the liquid absorbed by the sponge 54, allowing the liquid to return to the filtration system, thus completing the defoaming and liquid recovery process. During this process, the positioning frame 6 is connected to the bottom of the filter cylinder 1 by bolts to fix the position of the filter element 7, and the top cover 4 is slidably connected to the filter cylinder 1 to ensure that the foam elimination mechanism 5 can move up and down. The operation utilizes the foam elimination mechanism 5, which uses a sponge 54 to break the foam and the pressure plate 55 to recover the liquid. This eliminates the need for additional energy, achieving energy-saving defoaming, reducing liquid waste, and improving liquid utilization. The limiting tube 51 limits the vertical rod 52, making the downward pressing process more stable and ensuring the accuracy and effectiveness of the defoaming operation. The bolted connection between the positioning frame 6 and the filter cartridge 1 facilitates the installation and disassembly of the filter element 7, making equipment maintenance and cleaning convenient. The overall structure is rationally designed and easy to operate. The mechanical structure enables efficient defoaming, making it suitable for pharmaceutical filtration applications. It improves the stability of the filtration process and the quality of the liquid, reducing filtration efficiency loss or liquid loss caused by foam. It offers good practicality and economy.

[0023] Example 2: Figure 1 , Figure 3 and Figure 4 As shown, a cylinder 53 is fixedly installed on the outer wall of the vertical rod 52. The shape of the cylinder 53 is adapted to the limiting tube 51, and the cylinder 53 is located above the limiting tube 51. A tension spring 56 is fixedly installed on the upper surface of the inner side of the cylinder 53. One end of the tension spring 56 is fixedly connected to the upper surface of the top cover 4. A feed pipe 2 is connected to one side of the top of the filter cylinder 1, and a discharge pipe 3 is connected to the bottom of the filter cylinder 1. A permeation hole 8 is opened at the edge of the positioning frame 6.

[0024] The overall effect of this embodiment is that the liquid medicine enters the filter cylinder 1 from the feed pipe 2, flows through the permeation holes 8 on the edge of the positioning frame 6 to the filter element 7 for filtration, and is discharged from the discharge pipe 3. When the vertical rod 52 is pressed down, the cylinder 53 slides down along the limiting pipe 51, driving the pressing plate 55 and the sponge 54 to crush the foam on the positioning frame 6. The sponge 54 absorbs the foam liquid. After the vertical rod 52 is released, the tension force generated by the elastic deformation of the tension spring 56 pulls the cylinder 53 and the vertical rod 52 back to their original positions, causing the sponge 54 to leave the positioning frame 6, facilitating the next defoaming operation. The design of the cylinder 53 and the limiting tube 51, together with the tension spring 56, ensures the stable lifting and lowering of the vertical rod 52, making the defoaming operation continuous and precise. The automatic reset function of the tension spring 56 reduces the intensity of manual operation and improves the ease of use. The setting of the permeation hole 8 ensures the flow path of the medicine and does not affect the filtration efficiency. The overall structure achieves energy-saving defoaming through mechanical linkage, avoiding energy consumption, while reducing the loss of medicine due to foam and improving the utilization rate of medicine. In the pharmaceutical filtration scenario, it can ensure the stability of the filtration process and improve the quality of medicine and production efficiency.

[0025] The operating method and working principle of this device are as follows: The liquid medicine enters the filter cylinder 1 through the feed pipe 2, flows through the permeation holes 8 on the edge of the positioning frame 6 to the filter element 7 for filtration, and is discharged from the discharge pipe 3. When defoaming is required, the vertical rod 52 is pressed down, and the outer cylinder 53 slides down along the limiting pipe 51, which drives the pressing plate 55 and the sponge 54 to move downward. The sponge 54 contacts the foam on the upper surface of the positioning frame 6 and crushes the foam. The liquid is absorbed by the sponge 54. The pressing plate 55 continues to press down, squeezing out the liquid in the sponge 54 and returning it to the filtration system. After the vertical rod 52 is released, the tension spring 56 pulls the cylinder 53 and the vertical rod 52 back to their original positions due to the elastic deformation of the spring. The sponge 54 leaves the positioning frame 6, completing one defoaming cycle. The positioning frame 6 is connected to the bottom of the filter cylinder 1 by bolts to fix the position of the filter element 7. The top cover 4 is slidably connected to the filter cylinder 1 to ensure that the foam elimination mechanism 5 can move up and down. This process achieves energy-saving defoaming through mechanical linkage, reduces liquid medicine waste, and improves filtration efficiency and liquid medicine quality.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
