Description

Technical Field

[0001] This utility model relates to the field of ultrapure water filtration technology, specifically a filtration structure for ultrapure water equipment. Background Technology

[0002] The filtration structure of an ultrapure water system refers to a multi-module, staged, collaborative purification system designed to gradually purify raw water (such as tap water, groundwater, etc.) to ultrapure water standards (typically resistivity ≥18.2 MΩ・cm@25℃, total organic carbon (TOC) ≤5 ppb, and particle size ≤0.1 μm). It is not a single filtration component, but rather a series of filtration and purification units with different functions, specifically removing various contaminants such as particulate impurities, ions, organic matter, microorganisms, colloids, and dissolved gases from the water, ultimately outputting ultrapure water that meets the water requirements of specific industries (such as electronics, pharmaceuticals, and laboratories).

[0003] In this regard, Chinese utility model patent with authorization announcement number CN215924569U discloses a filter for an ultrapure water equipment, including a circular box, wherein the circular box is provided with a first filter structure and a second filter structure; the first filter structure includes: a first water tank, a second water tank, filter cotton, a partition, and a hemispherical body; a first water inlet pipe is installed on the upper wall of the first water tank, a discharge port is opened on the upper wall of the first water tank, a first drain port is opened at the upper end of the side wall of the first water tank, a first drain pipe is inserted into the first drain port, and the first drain pipe is connected to the second water tank.

[0004] In existing ultrapure water equipment, the filtration structure usually has the snap-fit ​​mechanism and the drain valve plate set separately. When the filter module needs to be cleaned or replaced, if the operator accidentally does not open the drain valve plate and directly removes the filter module, water will suddenly gush out, polluting the environment and affecting safe operation.

[0005] Therefore, we propose a filtration structure for ultrapure water equipment to solve the above problems. Utility Model Content

[0016] 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.

[0017] Example 1: Please see Figure 1-3 This utility model provides a technical solution: a filtration structure for an ultrapure water equipment, including a filter shell 1, a filter chamber 11 inside the filter shell 1, a water collection tank 12 on the bottom surface of the filter chamber 11, a wastewater pipe 22 fixed and connected to the bottom of the water collection tank 12, a second valve plate 23 rotatably mounted on the top of the wastewater pipe 22, a purified water pipe 2 fixed and connected to one side of the filter chamber 11, a first valve plate 21 rotatably mounted inside the purified water pipe 2, the opening and closing states of the first valve plate 21 and the second valve plate 23 being opposite; the filtered water flows from the purified water pipe 2 to a designated location. During filtration, the first valve plate 21 is in the open state and the second valve plate 23 is in the closed state. When internal cleaning is required, the first valve plate 21 is closed and the second valve plate 23 is opened, and the wastewater pipe 22 transports the residual water to the designated location.

[0018] The filter chamber 11 has an opening 13 on the side away from the purified water pipe 2. A filter screen frame 3 is inserted into the opening 13. A limiting plate 4 is rotatably installed on the bottom side of the filter shell 1. The limiting plate 4 contacts the side wall of the filter screen frame 3. The setting of the limiting plate 4 can fix the filter screen frame 3 in the opening 13 and limit the filter screen frame 3. When it is necessary to pull out the filter screen frame 3, rotate the limiting plate 4, and the limiting plate 4 moves away from the side wall of the filter screen frame 3. At this time, the filter screen frame 3 can be pulled out. The filter screen frame 3 is also equipped with a handle for user convenience.

[0019] Example 2: Please see Figure 1-3 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, and the water collection tank 12 is funnel-shaped. The funnel-shaped structure of the water collection tank 12 makes it easier to collect residual water.

[0020] The bottom of the filter housing 1 is provided with a worm gear 42 and a worm wheel 43. A first rotating rod 44 is rotatably provided at the bottom of the filter housing 1. A control rod 41 is rotatably provided on one side of the filter housing 1. The end of the first rotating rod 44 is fixedly connected to the side wall of the limiting plate 4. The worm wheel 43 is fixedly sleeved on the outer circumference of the first rotating rod 44. The end of the control rod 41 is fixedly connected to the worm gear 42. The worm gear 42 and the worm wheel 43 are meshed together. Rotating the control rod 41 causes the worm gear 42 to rotate, which in turn causes the worm wheel 43 to rotate. The worm wheel 43 then causes the first rotating rod 44 to rotate, which in turn causes the limiting plate 4 to rotate. The limiting plate 4 rotates 90 degrees and moves away from the filter screen frame 3.

[0021] A fixing block 14 is fixedly connected to one side of the filter housing 1. The purified water pipe 2 is fixedly connected to the top of the fixing block 14. The fixing block 14 is equipped with a first bevel gear 45 and a second bevel gear 46. A second rotating rod 47 is rotatably mounted on the top of the fixing block 14. The top end of the second rotating rod 47 passes through the purified water pipe 2 and is fixedly connected to the first valve plate 21. The bottom end of the second rotating rod 47 is fixedly connected to the second bevel gear 46. One end of the first rotating rod 44 is fixedly connected to the first bevel gear 45. The first bevel gear 45 and the second bevel gear 46 are meshed. When the first rotating rod 44 rotates, it drives the second valve plate 23 to rotate. The second valve plate 23 is in the open state at this time. When the first rotating rod 44 rotates, it also drives the first bevel gear 45 to rotate. The rotation of the first bevel gear 45 drives the second bevel gear 46 to rotate. The rotation of the second bevel gear 46 drives the second rotating rod 47 to rotate. The rotation of the second rotating rod 47 drives the first valve plate 21 to close.

[0022] A water spray frame 51 is fixedly installed on the top of the filter chamber 11. A water inlet pipe 5 is provided on the top of the filter shell 1. The water inlet pipe 5 passes through the filter shell 1 and is connected to the water spray frame 51. Water flows into the water spray frame 51 through the water inlet pipe 5 and then sprays from the water spray frame 51 onto the filter module 31. Multiple nozzles are installed on the water spray frame 51 for easy spraying.

[0023] The filter frame 3 has a filter module 31 installed inside; the filter module 31 can be detached and installed inside the filter frame 3, making it convenient for users to disassemble, replace and clean.

[0024] In use, the water to be filtered enters the spray frame 51 from the inlet pipe 5 and is sprayed onto the filter module 31. The filter module 31 filters the water, and the filtered water flows from the purification water pipe 2 to the designated location. In the filtering state, the first valve plate 21 is in the open state, the second valve plate 23 is in the closed state, and the limiting plate 4 contacts the filter screen frame 3, locking the filter screen frame 3 in place. When it is necessary to replace or clean the filter module 31, the control rod 41 is rotated. The rotation of the control rod 41 drives the worm gear 42 to rotate, which in turn drives the worm wheel 43 to rotate. The rotation of the worm wheel 43 drives the first rotating rod 44 to rotate, which in turn drives the limiting plate 4 to rotate. The limiting plate 4 rotates 90 degrees, moving away from the filter screen frame 3. At this time, the filter screen frame 3 can be pulled out from the opening 13. Simultaneously, the rotation of the first rotating rod 44 drives the second valve plate 23 to rotate, which is now in the open state. During rotation, the first bevel gear 45 is also driven to rotate, which in turn drives the second bevel gear 46 to rotate, which in turn drives the second rotating rod 47 to rotate, and the second rotating rod 47 to rotate, which in turn drives the first valve plate 21 to close. After standing for a period of time, the residual water enters the wastewater pipe 22 through the water collection tank 12 and is discharged to the designated location through the wastewater pipe 22. After standing, the user pulls the filter screen frame 3 out of the opening 13 to replace or clean the filter module 31, and then installs the filter screen frame 3 by reversing the steps. In this utility model, the limit plate 4, the first valve plate 21, and the second valve plate 23 are linked. When the filter module 31 needs to be replaced, the operator opens the limit plate 4. At this time, the first valve plate 21 closes and the second valve plate 23 opens, and the water is collected to the designated location through the wastewater pipe 22, which reduces the risk of operator misoperation, avoids sudden water gushing out, prevents environmental pollution, and improves the safety of operation.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
