Technical Field

[0001] This utility model relates to the field of membrane filtration equipment technology, and in particular to a high-purity hydrogen peroxide membrane filtration device. Background Technology

[0002] In the chemical and pharmaceutical industries, the purification and filtration of high-purity hydrogen peroxide is crucial. Membrane filtration, as a highly efficient separation technology, is widely used in the purification process of high-purity hydrogen peroxide.

[0003] However, existing membrane filtration devices have some problems in use. The membrane filter cartridge is installed solely by the housing, which is not stable enough. During the filtration process, it is prone to shaking due to liquid impact, affecting the filtration effect. At the same time, when replacing the membrane filter cartridge, the residual liquid material can easily flow along the outer wall of the membrane filter cartridge or drip into the installation groove of the filter cartridge, causing contamination of the outlet pipe and affecting product quality.

[0004] Therefore, this application provides a high-purity hydrogen peroxide membrane filtration device to meet the requirements. Utility Model Content

[0005] The purpose of this application is to provide a high-purity hydrogen peroxide membrane filtration device, which uses clamps to limit the movement, enhances the stability of the membrane filter element installation, and guides the residual material liquid out, thereby solving the problems mentioned in the background art and ensuring product quality.

[0006] To achieve the above objectives, this application provides the following technical solution: a high-purity hydrogen peroxide membrane filtration device, comprising a lower end cap, a tube plate at the top of the lower end cap, a filter element groove, a through hole, and a support on the tube plate, the filter element groove being used to install a membrane filter element, an adjusting rod on the support, two sets of adjusting rods being symmetrically arranged on both sides of the filter element groove, each adjusting rod having a clamp hinged at its end, the clamp matching the size of the membrane filter element, the clamp being used to limit the position of the membrane filter element, and an inlet pipe and an outlet pipe connected to the bottom of the lower end cap, the outlet pipe passing through the lower end cap and connected to the filter element groove.

[0007] Preferably, the support is detachably mounted on the tube sheet, a guide sleeve is hinged to the support, a threaded sleeve is connected to the outer end of the guide sleeve, the adjusting rod is slidably connected in the guide sleeve, and an adjusting bolt is rotatably connected to the outer end of the adjusting rod. The adjusting bolt is threadedly connected in the threaded sleeve, and the adjusting rod can be extended and retracted along the guide sleeve by rotating the adjusting bolt.

[0008] Preferably, the clamp is semi-circular, with a groove at one end and a block at the other end. The groove and the block are adapted to each other, and the block on one side of the clamp corresponds to the groove on the other side of the clamp. The ends of the two sets of clamps are inserted into each other to enhance the stability of the clamp when it is fastened to the membrane filter element.

[0009] Preferably, the bottom of the filter element groove is provided with a docking seat, which is used to mate with the end face of the membrane filter element. The docking seat is provided with a sealing groove, which is used to install a sealing ring.

[0010] Preferably, a flow guide groove is provided between the side wall of the filter element tank and the docking seat. The flow guide groove is arranged around the docking seat, and a flow guide hole is provided at the bottom of the flow guide groove. The flow guide hole has multiple sets and is evenly distributed, which can guide the material liquid flowing down when the membrane filter element is replaced.

[0011] Preferably, the lower end cap is provided with a support leg at the top, a housing is installed above the lower end cap by a quick-release clamp, a sealing ring is installed between the lower end cap and the housing, a pressure gauge is installed above the housing by a quick-release clamp, and a drain pipe is provided at the bottom of the lower end cap for draining liquid.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] 1. Secure Membrane Filter Cartridge Installation: Adjustable rods and clamps on both sides of the filter cartridge groove effectively limit the movement of the membrane filter cartridge. The adjustable rods extend and retract via the threaded connection in the threaded sleeve, thereby adjusting the position of the clamps to ensure a tight fit between the clamps and the membrane filter cartridge, preventing movement during filtration and guaranteeing stable filtration performance. Simultaneously, the natural deflection angle of the adjusting rods presses the membrane filter cartridge downwards, ensuring a tight fit between the cartridge and the filter cartridge groove. The interlocking clamps further enhance the stability of the membrane filter cartridge.

[0014] 2. Smooth Liquid Flow: The guide groove inside the filter element tank surrounds the docking seat. When replacing the membrane filter element, the residual liquid can be collected in the guide groove and then flow out through the guide hole, avoiding liquid residue in the filter element tank and ensuring the purity of liquid filtration. At the same time, the sealing groove on the docking seat is equipped with a sealing ring, which can ensure the sealing between the membrane filter element and the docking seat and prevent liquid leakage from affecting the filtration effect.

[0015] 3. Practical and reliable overall structure: The lower end cap and the shell are connected by quick-release clamps, facilitating the disassembly and assembly of the device and the maintenance of internal components; the pressure gauge allows for real-time monitoring of the internal pressure, ensuring safe operation; the drain pipe can empty the liquid inside the device when needed, facilitating cleaning and maintenance. The support legs ensure stable placement of the device, and the use of sealing rings guarantees the sealing of all connections. Attached Figure Description

[0027] As one implementation method in this embodiment, to achieve the adjustment function of the adjusting rod 5 on the clamp 6, such as... Figure 6 As shown, the support 50 is mounted on the tube sheet 10 by bolts and nuts. A guide sleeve 51 is hinged on the support 50. A threaded sleeve 52 is connected to the outer end of the guide sleeve 51. The adjusting rod 5 is slidably connected in the guide sleeve 51. An adjusting bolt 53 is rotatably connected to the outer end of the adjusting rod 5. The adjusting bolt 53 is threadedly connected in the threaded sleeve 52.

[0028] As one implementation method in this embodiment, to enhance the limiting effect of the clamp 6 on the filter element, such as... Figure 2 , Figure 3 As shown, the clamp 6 is semi-circular. One end of the clamp 6 is provided with a groove 60, and the other end of the clamp 6 is provided with a block 61. The groove 60 and the block 61 are adapted to each other. The position of the block 61 on one side of the clamp 6 corresponds to the groove 60 on the other side of the clamp 6.

[0029] As one implementation method in this embodiment, to ensure the filtration effect, such as Figure 7 As shown, the bottom of the filter element groove 14 is provided with a docking seat 16, which is used to dock with the end face of the membrane filter element 4. The docking seat 16 is provided with a sealing groove 17, which is used to install a sealing ring.

[0030] As one implementation method in this embodiment, to guide and remove residual liquid material, such as... Figure 7 As shown, a guide groove 18 is provided between the side wall of the filter element tank 14 and the docking seat 16. The guide groove 18 is arranged around the docking seat 16. A guide hole 19 is provided at the bottom of the guide groove 18. There are four sets of guide holes 19 and they are evenly distributed.

[0031] As one implementation method in this embodiment, and for ease of application in actual production, such as Figure 1 , Figure 6 As shown, the lower end cap 1 is provided with a support leg at the top, and a housing 2 is installed above the lower end cap 1 by a quick-release clamp. A sealing ring 7 is installed between the lower end cap 1 and the housing 2. A pressure gauge 3 is installed above the housing 2 by a quick-release clamp. A drain pipe 13 is also provided at the bottom of the lower end cap 1. The drain pipe 13 is used to drain liquid.

[0032] The working principle of this utility model is as follows: Before filtration, the membrane filter element 4 is installed and fixed. The membrane filter element 4 is placed in the filter element groove 14, with its end aligning with the docking seat 16. The sealing ring in the sealing groove 17 on the docking seat 16 ensures a tight seal between the two, preventing liquid leakage. Then, by rotating the adjusting bolt 53, the threaded connection between the adjusting bolt 53 and the threaded sleeve 52 causes the adjusting rods 5 on both sides to slide within their respective guide sleeves 51, thereby adjusting the position of the clamp 6. During this process, the hinged support of the support 50 allows the adjusting rods to... With one end of the hinge clamp 6 facing downwards, after the clamp 6 moves to the appropriate position, the two clamps 6 on both sides are fastened to the outside of the membrane filter element 4, so that the locking block 61 of one clamp 6 is embedded in the locking groove 60 of the other clamp 6, thereby connecting the two ends of the two sets of clamps 6 to achieve a stable limit on the membrane filter element 4 and prevent the membrane filter element 4 from shaking during filtration. Since the end of the adjusting rod 5 facing the clamp 6 is downwards, under the clamping of the two sets of clamps 6, the membrane filter element 4 is not only subjected to horizontal clamping force, but also to downward frictional force, so that the membrane filter element 4 is pressed tightly against the docking seat 16 and is not easy to separate.

[0033] During filtration, the high-purity hydrogen peroxide to be filtered enters the lower head 1 through the inlet pipe 11, and then flows upward through the through hole 15 on the tube sheet 10, making full contact with the membrane filter element 4 inside the shell 2. The membrane filter element 4 intercepts and separates impurities in the liquid by virtue of its own filtration performance, thereby achieving the purification of high-purity hydrogen peroxide.

[0034] The liquid filtered by the membrane filter element 4 flows downward along the inner cylinder of the membrane filter element 4 and eventually collects in the filter element tank 14, and then flows out through the outlet pipe 12. Since there is a guide groove 18 surrounding the docking seat 16 between the side wall of the filter element tank 14 and the docking seat 16, the filtered liquid can flow into the guide groove 18. The four sets of evenly distributed guide holes 19 at the bottom of the guide groove 18 will guide the liquid to the outlet pipe 12, and the liquid will then be discharged from the device through the outlet pipe 12, completing the filtration process.

[0035] Throughout the filtration process, the pressure gauge 3 on top of the housing 2 can monitor the internal pressure of the device in real time. Operators can judge the operating status of the device based on the data displayed by the pressure gauge 3. If the pressure is abnormal, corresponding measures can be taken in time to ensure the normal operation of the device.

[0036] When it is necessary to stop filtration and clean or maintain the device, the residual liquid in the device can be drained through the drain pipe 13. Then, remove the housing 2 and rotate the adjusting bolt 53 in the opposite direction to drive the adjusting rod 5. Disconnect the connection between the clamp 6 groove 60 and the clamp block 61. Rotate the adjusting bolt 53 in the opposite direction to move the clamp 6 away from the membrane filter element 4. The old membrane filter element 4 can then be removed and replaced with a new one. During this process, the residual liquid adhering to the membrane filter element 4 in the filter element groove 14, the tube sheet 10, and the outer wall of the membrane filter element 4 flows into the guide groove 18 and flows from the guide hole 19 to the bottom of the lower end cap 1, and is discharged from the drain pipe 13. Then, replace the membrane filter element 4 and reassemble the housing 2 and other accessories.
