Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment, specifically to a device for preparing water for injection using a membrane method. Background Technology

[0002] Water for injection refers to water that meets the requirements for water for injection as specified in the Chinese Pharmacopoeia. Water for injection has extremely high purity standards and is specifically designed for use in injection-related medical procedures. Its quality is subject to strict monitoring and testing. Water for injection must not contain any harmful impurities and has strict limits on the content of microorganisms, ensuring the safety of medical injections.

[0003] The membrane method for preparing water for injection first pre-treats the water source by sedimentation, filtration, and softening, and then sends it into a filter box for filtration. It is then sterilized by heating to generate high temperature and high pressure to ensure the purity of the water for injection. Finally, the water for injection is stored in a sterile container.

[0004] However, the process of preparing water for injection involves heating to generate high temperature and high pressure for sterilization, which increases energy consumption and poses safety hazards, making it impossible to produce safe and efficient water for injection.

[0005] In view of this, we propose an apparatus for preparing water for injection using a membrane method. Utility Model Content

[0006] The purpose of this invention is to provide a membrane-based apparatus for preparing water for injection, thereby solving the problem of high energy consumption in the preparation of water for injection mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An apparatus for preparing water for injection using a membrane method includes a filter box, a permeation device, a water purification device, a filter, and a connecting pipe. The filter box has an inlet and an outlet. The inlet is used to introduce water to be treated, and the outlet is used to discharge the pre-treated water. The filter box contains a first mounting plate and a second mounting plate, which provide mounting support. The first mounting plate contains the permeation device, which guides the incoming water to flow along a fixed loop. The tail end of the permeation device is located on the second mounting plate. The permeation device contains the water purification device, which performs preliminary filtration on the water to be treated. The outlet and the filter are connected via the connecting pipe. The pre-filtered water flows from the outlet of the filter box into the connecting pipe, and then into the filter. The filter performs secondary filtration on the pre-filtered water, ensuring the purity of the water. The filter has a drain outlet, from which the pre-filtered water for injection is discharged and collected by staff.

[0009] Preferably, the permeable device includes a permeable groove and an installation groove, the permeable groove and the installation groove are arranged perpendicularly and are connected; the permeable groove is connected to the inlet and the outlet, and a water purification device is fixedly installed in the installation groove. The water to be treated entering the filter box enters from the end connected to the inlet of the permeable groove, then passes through the water purification device in the installation groove, and is discharged from the end connected to the outlet.

[0010] Preferably, the water purification device includes a filter plate and a filter layer. The filter plate has a hollow structure, and the filter layer is fixedly installed inside the filter plate. The water source to be treated enters the filter plate and comes into contact with the filter layer inside the filter plate, thereby removing impurities from the water source and performing preliminary filtration.

[0011] Preferably, the filter layer is an RO membrane. The RO membrane can effectively remove ions, particulate matter and microorganisms from the water through its tiny pores. In addition, the RO membrane treatment process does not require heating, thus avoiding energy waste.

[0012] Preferably, the mounting groove is provided with an internal thread, and the filter plate is provided with a threaded groove that mates with the internal thread. The filter plate is fixedly connected to the internal thread on the mounting groove through the threaded groove, thereby realizing the connection between the water purification device and the permeation device. The use of threaded connection improves the tightness of the connection between the two, and at the same time, it facilitates the disassembly and maintenance of the water purification device, thereby facilitating the installation and disassembly of the filter plate, so as to replace the filter layer in a timely manner, ensuring the filtration effect of the water source and the safety of the production and use of injection water.

[0013] Preferably, the first mounting plate has a sealing groove, and the filter plate has a sealing ring that cooperates with the sealing groove. The sealing ring of the filter plate cooperates with the sealing groove to ensure the sealing performance of the filter plate and prevent the water source that has been initially filtered from leaking and mixing with the water source to be treated, which would cause leakage and reduce the filtration efficiency and filtration quality.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model achieves multi-stage filtration through a water purification device and filter, which improves the purity of water for injection. In particular, the use of an RO membrane as a filter layer can significantly improve the filtration effect and purity of the water source, ensuring the quality of water for injection. At the same time, it does not consume a large amount of heat energy, reducing production costs and improving production efficiency. Furthermore, the threaded connection facilitates disassembly and maintenance. Attached Figure Description

[0023] 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.

[0024] The membrane method for preparing water for injection first pre-treats the water source by sedimentation, filtration, and softening, and then sends it into a filter box for filtration. It is then sterilized by heating to generate high temperature and high pressure to ensure the purity of the water for injection. Finally, the water for injection is stored in a sterile container.

[0025] However, in the preparation of water for injection, high temperature and high pressure are generated by heating for sterilization. High temperature and high pressure sterilization requires a lot of energy to raise the temperature to the required temperature, which increases energy consumption. At the same time, excessively high temperatures pose safety hazards and may cause injury to workers, making it impossible to produce water for injection safely and efficiently.

[0026] like Figures 1 to 2 As shown, an apparatus for preparing water for injection using a membrane method includes a filter box 1, a permeation device 2, a water purification device 3, a filter 4, and a connecting pipe 5. The filter box 1 has an inlet 1 and an outlet 12. The filter box 1 has a first mounting plate 13 and a second mounting plate 14. The permeation device 2 is located inside the first mounting plate 13, and the tail end of the permeation device 2 is located on the second mounting plate 14. The water purification device 3 is located inside the permeation device 2. The outlet 12 and the filter 4 are connected by the connecting pipe 5. The filter 4 has a drain outlet 41.

[0027] Specifically, the filter box 1 is provided with an inlet 11 and an outlet 12. The inlet 11 is used to introduce water to be treated, and the outlet 12 is used to discharge the water that has undergone preliminary treatment. The filter box 1 is provided with a first mounting plate 13 and a second mounting plate 14, which serve as mounting supports. The first mounting plate 13 has mounting holes through which a permeable device 2 is fixedly installed. The permeable device 2 is used to guide the incoming water to be treated, allowing the water to flow along a fixed loop. The tail end of the permeable device 2 is located on the second mounting plate 14, which provides support for the permeable device. The interior of the permeable device 2... A water purification device 3 is provided, which is used to perform preliminary filtration on the device to be treated. The outlet 12 and the filter 4 are connected by a connecting pipe 5. The connecting pipe 5 is fixedly connected to the outlet 12 and the filter 4 by a threaded connection. The water source that has been preliminarily filtered by the water purification device 3 flows out from the end of the permeable channel 21 connected to the outlet 12, and then flows into the connecting pipe 5 from the outlet 12. The connecting pipe 5 sends the preliminarily filtered water source into the filter 4. The filter 4 performs secondary filtration on the preliminarily filtered water source, thereby ensuring the purity of the water source. The filter 4 is provided with a drain outlet 41. The secondary filtered water for injection is discharged from the drain outlet 41 and collected by the staff.

[0028] In this embodiment, the permeable device 2 includes a permeable groove 21 and a mounting groove 22. The permeable groove 21 and the mounting groove 22 are arranged perpendicularly and are connected. The permeable groove 21 is connected to the inlet 11 and the outlet 12. A water purification device 3 is fixedly installed in the mounting groove 22.

[0029] Specifically, the water to be treated enters the filter box 1 from the end connected to the inlet 11 of the permeable trough 21, then passes through the water purification device 3 in the installation trough 22, and is discharged from the end connected to the outlet 12.

[0030] In this embodiment, the water purification device 3 includes a filter plate 31 and a filter layer 32. The filter plate 31 has a hollow structure, and the filter layer 32 is fixedly installed inside the filter plate 31.

[0031] Specifically, the water to be treated enters the filter plate 31 through the permeation device 2 and comes into contact with the filter layer 32 inside the filter plate 31, thereby removing impurities from the water to be filtered and performing preliminary filtration.

[0032] In this embodiment, the filter layer 32 is an RO membrane;

[0033] Specifically, RO membranes are suitable for various water quality conditions. They have strong corrosion and fouling resistance, can operate stably in harsh environments, extend their service life, and reduce maintenance frequency. At the same time, RO membranes have high filtration efficiency and energy-saving and environmental protection properties. Through their tiny pores, RO membranes can effectively remove ions, particulate matter, microorganisms, and salt content from water, ensuring the purity of water for injection. RO membranes reduce the use of chemicals and wastewater treatment costs, and reduce environmental pollution. In addition, the RO membrane treatment process does not require heating, avoiding energy waste.

[0034] Preferably, the water purification device 3 improves filtration quality and increases the purity of the water source by using an RO membrane, avoids heating treatment, reduces production costs, and improves production efficiency.

[0036] Specifically, the filter plate 31 is fixedly connected to the mounting groove 22 by the internal thread, thereby realizing the connection between the water purification device 3 and the permeation device 2. The use of threaded connection improves the tightness of the connection between the two, and at the same time, it facilitates the disassembly and maintenance of the water purification device 3, thereby facilitating the installation and disassembly of the filter plate 31, so as to replace the filter layer 32 in a timely manner, ensuring the filtration effect of the water source and the safety of the production and use of injection water.

[0037] In this embodiment, a sealing groove is provided on the first mounting plate 13, and a sealing ring that cooperates with the sealing groove is provided on the filter plate 31;

[0038] Specifically, the sealing ring of the filter plate 31 cooperates with the sealing groove to ensure the sealing performance of the filter plate 31, and prevent the water source that has been initially filtered from leaking and mixing with the water source to be treated, which would reduce the filtration efficiency and filtration quality.

[0039] In use, the membrane-based apparatus for preparing water for injection of this invention introduces a water source to be treated, which is input through the inlet 11 of the filter box 1. The water source is driven to enter the permeation device 2 through one end of the permeation groove 21. The water source to be filtered comes into contact with the water purification device 3 inside the permeation device 2 and undergoes primary filtration through the RO membrane inside the water purification device 3. The water source that has completed primary filtration is discharged from the other end of the permeation device 2 into the outlet 12, and then flows from the outlet 12 into the filter 4 through the connecting pipe 5. It undergoes secondary filtration in the filter 4 to produce water for injection, and then is discharged and collected through the drain outlet 41 on the filter 4.
