Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, in particular to a semiconductor pure water treatment device with cleaning and filtering functions. Background Art

[0002] Semiconductors refer to materials with electrical conductivity between conductors and insulators at room temperature. Common semiconductor materials include silicon, germanium, gallium arsenide, silicon carbide, gallium nitride, silicon nitride, and perovskite. Silicon is the most widely used semiconductor material. The semiconductor industry, which has developed based on semiconductors, belongs to the electronics and information industry and is considered a hardware industry. The semiconductor industry can be divided into four categories: integrated circuits, discrete devices, optoelectronic devices, and sensors. Integrated circuits are the most important, accounting for over 80% of the market's commercial output value.

[0003] Chip manufacturing uses single-crystal silicon wafers as the substrate, then uses techniques such as photolithography, doping, and CMP to create components such as MOSFETs and BJTs. Thin-film and CMP techniques are then used to create the conductors. Industrial ultrapure water is required at multiple steps in the semiconductor manufacturing process to prevent impurities from interfering with the quality of semiconductors, which require high-precision processing. Ultrapure water is produced using distillation, deionization, reverse osmosis, or other appropriate supercritical fine processing techniques to develop ultrapure materials. Simply put, it is water from which virtually all atoms except oxygen and hydrogen have been removed.

[0004] Producing ultrapure water from common water sources, such as tap water, requires multiple purification steps, including filtration. Currently, existing water filtration equipment generally uses filter cartridges installed in water tanks to filter water. After a period of use, impurities or high concentrations of ions in the water remain in the filter cartridges, gradually clogging them. This requires frequent filter cartridge replacement, resulting in high operating costs. Furthermore, the replacement process requires the equipment to suspend water purification operations, resulting in the purification system's inability to output ultrapure water stably over the long term, impacting the industrial production of semiconductors.

The above-mentioned semiconductor pure water treatment device with cleaning and filtering functions is adopted. This device uses a movable cleaning disc to clean the filter cartridge. At the same time, due to the movement of the cleaning disc, the sealed space above gradually increases.

When the subsequent cleaning disc rises again, these sewage can be input into the waste liquid cartridge through the one-way valve for discharge. This device has an automatic cleaning effect, and compared with traditional direct backwash cleaning, this device has stronger cleaning power, can effectively extend the service life of the filter cartridge, and does not require shutdown for cleaning and replacement, ensuring the stable output of purified water, and providing a guarantee for stable industrial production of semiconductors.

DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1 to 7In the embodiment of the present invention, a semiconductor pure water treatment device with cleaning and filtering functions includes a primary cylinder 1, a secondary cylinder 2, a tertiary cylinder 3 and a water inlet cylinder 4; the primary cylinder 1, the secondary cylinder 2, the tertiary cylinder 3 and the water inlet cylinder 4 are connected in sequence; a filtering structure 7 is installed in the tertiary cylinder 3, and the filtering structure 7 includes a plurality of filter cylinders 71 vertically inserted in the tertiary cylinder 3, a cleaning disc 73 is slidably installed in the filter cylinder 71; a guide rod 72 is installed on the cleaning disc 73, and the guide rod 72 is inserted into the interior of the secondary cylinder 2; a water inlet 42 is installed on the water inlet cylinder 4, and the water inlet cylinder 4 is connected to the interior of each filter cylinder 71; the secondary cylinder 2 is divided into a regulating cylinder 22 and a waste liquid cylinder 21, and a one-way valve 74 connecting the interior of each filter cylinder 71 is installed in the waste liquid cylinder 21; a water outlet 31 is installed on the tertiary cylinder 3, and a waste water outlet 211 is installed on one side of the waste liquid cylinder 21; A plurality of lifting structures 6 are installed in the regulating cylinder 22. The guide rod 72 passes through the waste liquid cylinder 21 and is connected to the lifting structure 6. The lifting structure 6 is used to control the insertion and removal of the guide rod 72 in the filter cylinder 71. A control structure 5 is installed in the first-stage cylinder 1 . The control structure 5 is connected to each lifting structure 6 . The control structure 5 is used to provide drive for the lifting structures 6 .

[0026] The tertiary cylinder 3 and the water inlet cylinder 4 of this device serve as the main filtering areas. A plurality of filter cylinders 71 are installed in the tertiary cylinder 3. The filter cylinder 71 is open at one end close to the water inlet cylinder 4 and closed at one end close to the waste liquid cylinder 21. A one-way valve 74 is provided at the connection with the waste liquid cylinder 21. The one-way valve 74 only allows liquid to enter the waste liquid cylinder 21 from the inside of the filter cylinder 71 and does not allow reverse flow. A cleaning disc 73 is installed in the filter cylinder 71. The cleaning disc 73 is controlled by a guide rod 72 inserted into the filter cylinder 71. During normal filtration, the cleaning disc 73 is located in a position that fits the one-way valve 74, blocking the one-way valve 74. Therefore, during normal water purification, there will be no problem of water being discharged from the one-way valve 74.

[0027] During the water purification process, water enters the interior of the filter cartridge 71 from the water inlet cylinder 4. Under the action of water pressure, the water passes through the filter cartridge 71, enters the tertiary cylinder 3, and is discharged from the water outlet 31. When a large amount of impurities accumulate in part of the filter cartridge 71, affecting the filtration effect, the control structure 5 and the lifting structure 6 can be coordinated to control the guide rod 72 to be inserted into the filter cartridge 71. That is, the cleaning disc 73 continuously moves inside the filter cartridge 71. The edge of the cleaning disc 73 scrapes against the inner wall of the filter cartridge 71, peeling off stubborn impurities from the inner wall of the filter cartridge 71.

[0028] The cleaning disc 73 divides the filter cartridge 71 into two sections. The lower section continues to apply pressure to the outside of the filter cartridge 71 to clean water. Since the upper section does not contact the water inlet cylinder 4, the clean water will enter the filter cartridge 71 under the action of water pressure, and flush the filter cartridge 71 in this process, thereby improving the effect of cleaning the filter cartridge 71. As the cleaning disc 73 moves, the space in the upper end area continues to increase, and the negative pressure generated will actively draw water into the filter cartridge 71, so that the intensity of clean water flushing the filter cartridge 71 is higher than the flushing intensity of the clean water directly pressed into the filter cartridge by the natural water pressure in the three-stage cylinder, thereby further improving the flushing effect.

[0029] After the cleaning disc 73 moves to the bottom, it is pulled upward again, squeezing the flushed area of the filter cartridge 71. The sewage enters the waste liquid cartridge 21 through the one-way valve 74 and is discharged from the waste water outlet 211. The interior of the filter cartridge 71 is cleaned twice by the cleaning disc 73, and the cleaning effect is far greater than that of direct flushing. In addition, when squeezing the internal water toward the waste liquid cartridge 21, due to the greater internal pressure, in addition to sending the waste water into the waste liquid cartridge 21, a small amount of waste water is filtered and discharged again. Therefore, compared with direct flushing equipment, the proportion of waste water discharged by this device is significantly reduced, reducing the waste of water resources during the cleaning process.

[0030] As another embodiment of the present invention, see Figures 1 to 3 A primary baffle 11 is installed at the connection between the primary cylinder 1 and the secondary cylinder 2; a secondary baffle 23 is installed at the connection between the regulating cylinder 22 and the waste liquid cylinder 21; a tertiary baffle 32 is installed at the connection between the tertiary cylinder 3 and the secondary cylinder 2; and a quaternary baffle 43 is installed at the connection between the water inlet cylinder 4 and the secondary cylinder 2. The primary baffle 11, the secondary baffle 23, the tertiary baffle 32, and the quaternary baffle 43 are used to divide the internal space of the device into different areas and to limit and reinforce the structures installed in each area.

[0031] See also Figures 1 to 3 The one-way valve 74 is mounted on the third-stage partition 32. The fourth-stage partition 43 is provided with through-holes 431 corresponding to the positions of the respective filter cartridges 71. A support frame 41 is mounted on the exterior of the water inlet cartridge 4. The one-way valve 74 connects the space at the center of the filter cartridge 71 with the waste liquid cartridge 21 for draining wastewater. The through-holes 431 directly deliver the input water into the interior of the filter cartridge 71 for filtration. The support frame 41 provides overall support for the device. The first-stage cartridge 1, the second-stage cartridge 2, the third-stage cartridge 3, and the water inlet cartridge 4 can be connected using screws, welding, or a variety of other methods. The connection method is not restrictive and is not specifically limited.

[0032] See also Figures 2 to 3The cleaning disc 73 is externally mounted with a scraper 731 made of an elastic material, the outer edge of which fits against the inner wall of the filter cartridge 71. The scraper 731 is made of a flexible material, which allows it to better fit the inner edge of the filter cartridge 71, achieving a better cleaning effect. It also allows the filter cartridge 71 to be separated into two areas, allowing better use of water pressure to flush and clean the filter cartridge 71.

[0033] See also Figures 2 to 5 The lifting structure 6 includes an adjusting screw 61 that passes through the primary cylinder 1 and the adjusting cylinder 22. A threaded cylinder 63 is threadedly connected to the adjusting screw 61. A shuttle-shaped connecting plate 62 is installed on the outside of the threaded cylinder 63. The two ends of the connecting plate 62 are connected to two adjacent guide rods 72. The threaded cylinder 63 is restricted by the connecting plate 62 and the two guide rods 72 and cannot rotate. The rotation of the adjusting screw 61 will be converted into the up and down movement of the threaded cylinder 63, and drive the guide rods 72 to move. The lifting structure 6 used in this device is only used as a demonstration of a structure with a lifting effect and should not be regarded as a restrictive structure. In addition to using the adjusting screw 61 to drive, a scissor structure or a hydraulic rod or other structure can also be used for control. In addition to using one adjusting screw 61 to drive two or more guide rods 72, each guide rod 72 can also be independently controlled so that only one filter cylinder 71 in the filter structure 7 is in the cleaning process at the same time, ensuring a stable discharge volume of clean water.

[0034] See also Figures 2 to 7 The control structure 5 includes a primary motor 51 mounted within the primary cylinder 1. The primary motor 51 is connected to a drive gear 55. A plurality of transmission wheels 52 are mounted within the primary cylinder 1 and distributed around the drive gear 55. A driven gear 64 is mounted on the adjustment screw 61. The ends of the transmission wheels 52 are connected to the drive gear 55 and the driven gear 64, respectively. The primary motor 51 drives the drive gear 55, which is then transmitted to the driven gear 64 via the transmission wheels 52, thereby controlling the adjustment screw 61.

[0035] See also Figures 4 to 7The transmission wheel frame 52 includes a transmission gear 521 rotatably mounted within the primary cylinder 1. A transmission frame 523 is rotatably mounted on the transmission gear 521. An auxiliary gear 522 is rotatably mounted on the end of the transmission frame 523 away from the transmission gear 521. The transmission gear 521 meshes with the auxiliary gear 522. A limit rod 524 is mounted on the transmission frame 523. The position of the transmission gear 521 is fixed, while the position of the auxiliary gear 522 can be changed as the transmission frame 523 rotates. By rotating the transmission frame 523, the auxiliary gear 522 can be placed in a position of meshing with the driven gear 64 or out of meshing with the driven gear 64. Therefore, by adjusting the transmission frame 523, the drive of the drive gear 55 can be transmitted to a specific adjustment screw 61, thereby achieving the function of the device to clean only part of the filter cartridges 71 at a time.

[0036] See also Figures 4 to 7 A drive ring 53 is rotatably mounted within the first-stage cylinder 1. The drive ring 53 has an annular track groove 531 formed therein. A protruding ejection groove 532 is provided at one end of the track groove 531, and the limiting rod 524 is inserted into the track groove 531. The drive ring 53 uses the annular track groove 531 to constrain the limiting rod 524, and a portion of the track groove 531 protrudes outward. By rotating the drive ring 53, the limiting rod 524 corresponding to a particular transmission wheel frame 52 is pushed outward by the ejection groove 532, thereby connecting the transmission wheel frame 52 to the corresponding lifting structure 6 and driving the designated guide rod 72. The drive ring 53 is not a restrictive structure. In addition to utilizing the rotation of the drive ring 53 in conjunction with the specially shaped track groove 531 for control, an independent hydraulic lever or electric push rod, etc., can also be provided for each transmission wheel frame 52 as a drive, or an independent motor drive can be provided for each adjustment screw 61, thereby achieving the same effect.

[0037] See also Figures 4 to 7 A ring gear 533 is mounted on the outside of the drive ring 53. A secondary motor 54 is mounted on one side of the primary cylinder 1. A driving gear 56 is mounted on the secondary motor 54. The driving gear 56 is meshed with the ring gear 533. The secondary motor 54 drives the driving gear 56 to drive the ring gear 533, thereby driving the drive ring 53.

[0038] The working principle of the present invention is: This device is provided with a primary cylinder 1, a secondary cylinder 2, a tertiary cylinder 3 and a water inlet cylinder 4 connected in sequence. A plurality of filter cylinders 71 connected to the water inlet cylinder 4 are provided in the tertiary cylinder 3. A control structure 5 and a lifting structure 6 are respectively installed in the primary cylinder 1 and the secondary cylinder 2. The lifting structure 6 can control the cleaning disc 73 inserted into the filter cylinder 71, and a one-way valve 74 is installed at the connection between the internal space of the filter cylinder 71 and the secondary cylinder 2. During normal filtration, water passes through the filter cylinder 71 from the water inlet cylinder 4 and enters the tertiary cylinder 3 before being discharged. When the filter cylinder 71 needs to be cleaned, the cleaning disc 73 moves in the filter cylinder 71 to scrape and clean it. At the same time, the negative pressure generated by the movement of the cleaning disc 73 causes the clean water outside to flush the filter cylinder 71, thereby improving the cleaning effect. After cleaning, the waste water enters the secondary cylinder 2 through the one-way valve 74 and is discharged. This device can automatically clean the filter cartridge 71 with high cleaning efficiency and low cleaning cost, thereby ensuring the ability to output pure water and ensuring the stable output of pure water during semiconductor processing.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
