Description

Technical Field

[0001] The utility model relates to the technical field of ultrapure water, in particular to ultrapure water equipment. Background Art

[0002] In the prior art, ultrapure water refers to water with almost no impurities, no bacteria, viruses, organic matter such as chlorinated dioxins, and no mineral trace elements required by the human body, that is, water from which almost all atoms except oxygen and hydrogen have been removed. During the treatment of ultrapure water, the raw water needs to be filtered to remove the impurities contained therein. The existing treatment device cannot efficiently clean the impurities remaining after filtration during filtration, which is inconvenient.

[0003] After searching, the Chinese patent application number 201921087400.5 discloses a multi-stage ultrapure water equipment, including a fixed box body, on the bottom inner wall of the fixed box body, a first purification box and a second purification box are fixedly installed, and a collecting box is provided on the bottom inner wall of the fixed box body. The collecting box is located between the first purification box and the second purification box. A filter plate is rotatably installed on the inner wall of one side of the second purification box, and a connecting groove is opened on the inner wall of the other side of the second purification box. A connecting block is slidably installed in the connecting groove, and one side of the connecting block is rotatably installed on the filter plate.

[0004] A multi-stage ultrapure water device in the above patent has the following shortcomings: when the bristles are brushing back and forth on the filter plate, the filter plate is still filtering during this process. During the resetting process of the bristles, the impurities will be pushed to one side of the second purification box away from the blocking plate pair. The impurities move repeatedly on the filter plate, and the effect of impurity removal cannot be guaranteed. Utility Model Content

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0033] Embodiment 1:

[0034] Ultrapure water equipment, in order to facilitate the filtration of water, such as Figure 1-6 As shown, it includes a base 1 and a filter part, and the filter part includes:

[0035] Bracket 2: It is welded to the top outer wall of the base 1, and a filter cartridge 3 is welded to one end of the bracket 2;

[0036] Annular filter screen 11: It is welded to the inner wall of the top of the filter cartridge 3, and the outer wall of the annular filter screen 11 is provided with filter holes 14

[0037] Cover plate 1 9: It is threadedly connected to the top of the annular filter screen 11;

[0038] T-shaped rod 13: it is slidably connected to the inner wall of the through hole opened on the surface of cover plate 9, and the bottom of the T-shaped rod 13 is connected to the scraper 10 adapted to the inner diameter of the annular filter screen 11 through a thread;

[0039] When it is necessary to filter water, firstly, the annular filter screen 11 and the top of the filter cylinder 3 are threadedly connected. After the connection is completed, after the water enters the annular filter screen 11, the impurities in the water can be filtered by using the filter holes 14. The filtered impurities are trapped on the circumferential inner wall of the annular filter screen 11, and the filtered water is discharged through the filter holes 14 on the annular filter screen 11. When the impurities attached to the circumferential inner wall of the annular filter screen 11 are trapped to a certain extent, the T-bar 13 is pressed to make the scraper 10 scrape the attached impurities while sliding along the circumferential inner wall of the annular filter screen 11. The scraped impurities are discharged along the bottom of the annular filter screen 11, thereby avoiding the impurities accumulating on the circumferential inner wall of the annular filter screen 11 for a long time to block the filter holes 14, thereby affecting the normal filtration of water.

[0040] Furthermore, a pipeline is welded to the side wall of the annular filter screen 11, and one end of the pipeline is connected to a three-way valve 5 through a flange;

[0041] In this embodiment, the number of filter parts is preferably two groups, and the two groups of filter parts are connected by pipes and a three-way valve 5. By providing two groups of filter parts, the water to be filtered can be diverted, and impurities in the water can be prevented from being excessively concentrated on the circumferential inner wall of an annular filter screen 11, thereby extending the cleaning cycle of the circumferential inner wall of the annular filter screen 11. When it is necessary to clean the circumferential inner wall of one of the annular filter screens 11, the three-way valve 5 is switched on and off to close one of the pipeline branches, thereby cleaning the annular filter screen 11 corresponding to the pipeline branch, and during this process, the other filter part can continue to filter the water, thereby ensuring that the entire filtration system can achieve non-stop operation.

[0042] Further, a vertical plate 7 is welded to the outer wall of the top of the base 1, a connecting pipe 6 is welded to the inner wall of the through hole opened on the surface of the vertical plate 7, and the two connecting pipes 6 are connected through a three-way valve 8, a connecting plate 17 is welded to the top of the connecting pipe 6, and a bellows 16 is embedded in the top of the connecting plate 17, and a mounting plate 19 is embedded in one end of the bellows 16 away from the connecting plate 17, and the top of the mounting plate 19 is rotatably connected to the bottom plate 12, and the bottom plate 12 and the bottom of the filter cartridge 3 are threadedly connected, and the top of the bottom plate 12 is annularly opened with a water outlet hole that is connected to the bellows 16;

[0043] The bottom plate 12 and the bottom of the filter cartridge 3 are threadedly connected, so that the bottom of the filter cartridge 3 can be sealed by the bottom plate 12, and after the bottom plate 12 is connected, the bottom of the annular filter screen 11 and the upper surface of the bottom plate 12 are in contact with each other, thereby preventing water from overflowing through the bottom of the annular filter screen 11 during the filtration process. The bellows 16 is retractable, so that during the threaded connection between the bottom plate 12 and the bottom of the filter cartridge 3, it plays a connecting role between the mounting plate 19 and the connecting plate 17.

[0044] Furthermore, a slide bar 15 is fixed to the bottom of the mounting plate 19, and a telescopic sleeve 18 is fixed to the top of the connecting plate 17, and the slide bar 15 and the telescopic sleeve 18 are slidably connected;

[0045] The bottom plate 12 can be guided relative to the connecting plate 17 by providing the slide rod 15 and the telescopic sleeve 18 . When the bottom plate 12 and the bottom of the filter cartridge 3 are threadedly connected, it can be ensured that the bottom plate 12 is accurately screwed into the bottom of the filter cartridge 3 .

[0046] Working principle: When it is necessary to filter water, first insert the cover plate 9 into the filter cartridge 3 and then weld and fix it. Then use the three-way valve 5 to introduce the water into the annular filter screen 11 through two pipes. After the water enters the annular filter screen 11, the filter holes 14 are used to filter the impurities in the water. The filtered water is discharged through the filter holes 14 and finally discharged through the bellows 16 and the three-way valve 8.

[0047] When it is necessary to clean the impurities attached to the inner wall of the annular filter 11, the bottom plate 12 is detached from the bottom of the filter cylinder 3. At this time, the bottom of the annular filter 11 is in an open state. By pressing down the T-bar 13, the impurities are discharged from the bottom of the annular filter 11 under the scraping action of the scraper 10.

[0048] Embodiment 2:

[0049] Ultrapure water equipment, such as Figure 3As shown, in order to ensure that the scraper 10 can be reset after scraping the circumferential inner wall of the annular filter screen 11; this embodiment makes the following supplements on the basis of embodiment 1: the circumferential outer wall of the T-shaped rod 13 is sleeved with a spring 4, and the two ends of the spring 4 are respectively fixed to the top inner wall of the T-shaped rod 13 and the top outer wall of the cover plate 9 by a clamping method;

[0050] The spring 14 is provided so that the scraper 10 can be reset after cleaning the inner wall of the annular filter screen 11 by scraping.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
