Description

Technical Field

[0001] The utility model relates to the field of water treatment, in particular to an ultrapure water treatment and recycling device. Background Art

[0002] Ultrapure water is a type of high-purity water that has gone through a series of rigorous treatment and purification processes to remove almost all impurities, ions and organic matter to reach extremely high purity standards. Ultrapure water is often used in a variety of applications that require high-purity water quality, such as laboratory research, semiconductor manufacturing, pharmaceutical production, power industry, etc.

[0003] When the existing ultrapure water recycling device is used in a recycling manner, multiple groups of filter cartridges are arranged inside to filter impurities from the ultrapure water so that it can be recycled.

[0004] When installing the existing filter cartridge, it is necessary to firmly install its cavity and the bottom end of the filter box to prevent the installation from tilting, which leads to low water filtration efficiency. At the same time, the filter cartridge will expand after long-term use to fit the inner wall of the filter box, which is troublesome and inconvenient to disassemble later. The existing filter box is usually provided with an external thread on its outer wall, and the cover body is locked to the outer wall of the filter box through the internal thread of the filter box cover. Since there are multiple groups of filter cartridges, when multiple groups of filter cartridges are replaced, the multiple groups of covers need to be manually disassembled and repeatedly rotated for installation, which is time-consuming and labor-intensive. Therefore, an ultrapure water treatment recycling device is proposed to solve the above problems. Utility Model Content

[0030] Reference Figure 2-Figure 3 The locking cam 76 is provided on the top of the locking cam 74 so that the locking cam 74 can be locked to the locking cam 74 when the locking cam 74 is engaged. When the locking cam 75 is in place, the locking cam 73 is in place and the locking cam 73 is in place when the locking cam 73 is in place.

[0031] Reference Figure 1 and Figure 4The fixing assembly 6 includes a fixing block 61, the inner wall of the fixing block 61 is elastically connected with a wedge block 63 through a limiting spring 62, the bottom end of the outer wall of the fixing block 61 is fixedly connected to the top end of the outer wall of the fixing seat 5, one end of the limiting spring 62 is fixedly connected to the outer wall of the wedge block 63, and the other end of the limiting spring 62 is fixedly connected to the inner wall of the fixing block 61. The function of the limiting spring 62 is to automatically reset the position of the wedge block 63 after squeezing and moving it. The wedge block 63 is slidably connected to the inner wall of the fixing block 61, and a slot is provided on the outer side wall of the mounting seat 71. The wedge block 63 is clamped with the inner wall of the slot, and the clamping between the two fixes the mounting seat 71 to the inner wall of the fixing seat 5 to avoid the mounting seat 71 from loosening due to long-term use.

[0032] Working principle: when installing the filter cartridge 8, the through hole at the top of the filter cartridge 8 can be inserted between the two groups of clamping blocks 72. At this time, the moving rod 73 can be directly pressed to move on the inner wall of the mounting seat 71. The moving rod 73 will drive the trapezoidal block 76 to descend synchronously during the descent process. At the same time, the card groove on its surface will also squeeze the inclined surface of the limit block 75, and push the limit block 75 outward on the inner wall of the mounting seat 71 until the next group of card grooves. It will be elastically acted upon by the reset spring 74 and restored to its initial position, thereby fixing the moving rod 73. At the same time, when the trapezoidal block 76 follows the moving rod 73 to descend, the inclined surfaces of the triangular blocks 77 sliding on the outer walls on both sides will be squeezed, so that the two groups of triangular blocks 77 drive the clamping blocks 72 to move outward synchronously, thereby clamping and fixing the inner wall of the filter cartridge 8.

[0033] During installation, the filter cartridge 8 and the mounting seat 71 can be inserted into the interior of the filter box 3 together. When the mounting seat 71 is inserted into the interior of the filter box 3, the outer wall of the mounting seat 71 will squeeze the inclined surface of the wedge block 63, pushing it outward on the inner wall of the fixing block 61 until the mounting seat 71 is completely installed on the inner wall of the filter box 3. The wedge block 63 will be elastically acted upon by the limit spring 62, restoring it to its original position, thereby fixing the mounting seat 71. At this time, the bottom end of the mounting seat 71 will contact the top end of the sealing ring 9 on the inner wall of the fixing seat 5, thereby sealing the mounting seat 71 and the inner wall of the fixing seat 5 through the sealing ring 9.
