Description

Technical Field

[0001] The utility model belongs to the technical field of circulating water treatment, in particular to a circulating water treatment device. Background Art

[0002] Circulating water processors use specially formulated water treatment agents to effectively prevent metal oxidation corrosion and electrochemical corrosion, reducing energy consumption.

DETAILED DESCRIPTION

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] Example 1

[0035] A circulating water treatment device includes a reaction chamber 1, a reagent chamber 2 disposed at the top of the reaction chamber 1, and a filter chamber 3 disposed at the bottom of the reaction chamber 1. A liquid inlet pipe 4 is disposed on the reaction chamber 1. In other words, the reagent chamber 2, reaction chamber 1, and filter chamber 3 are disposed in this order from top to bottom.

[0036] The system further comprises: a reagent adding assembly implemented in the reagent chamber 2 and the reaction chamber 1, the reagent adding assembly being used to add the water treatment agent in the form of a rotating fluid into the reaction chamber 1. Furthermore, the reagent adding assembly has a stirring function.

[0037] A filter screen 5 is installed within the filter chamber 3. The filter screen 5 comprises a horizontal filter section 501 and inclined filter sections 502 at either end. The horizontal filter section 501 is used to filter sludge from the liquid, while the inclined filter sections 502 are used to direct the filtered sludge for discharge. Correspondingly, two sets of sludge recovery chambers 6 are located on either side of the filter chamber 3. The bottoms of the inclined filter sections 502 extend into the corresponding sludge recovery chambers 6, each of which is equipped with a sewage pipe 7.

[0038] In order to realize the guided discharge of sludge, an auxiliary cleaning component is provided between the reagent adding component and the filter screen 5. In order to ensure that water treatment and sludge treatment are carried out simultaneously without internal accumulation, the reagent adding component and the auxiliary cleaning component are transmission-connected to the same power source.

[0039] like Figure 2 As shown, the power source includes: a forward and reverse motor 8, and a rotating shaft 9 that is transmission-connected to the output shaft of the forward and reverse motor 8.

[0040] Furthermore, the reagent adding assembly includes: a reagent main pipe 101 whose bottom is connected to the rotating shaft 9. Therefore, the reagent main pipe 101 is a hollow structure, and its top extends to the opening of the reagent chamber 2. Correspondingly, a plurality of groups of reagent auxiliary pipes 102 are connected to the bottom periphery of the reagent main pipe 101 at equal distances in the radial direction, and each group of reagent auxiliary pipes 102 is provided with a plurality of nozzle pipes 103, and the nozzle pipes 103 are provided with a plurality of injection holes 104, such as Figure 3 shown.

[0041] When the reagent is used, the reagent is added into the reagent main pipe 101 through the opening of the reagent chamber 2. The reagent main pipe 101 rotates under the action of the forward and reverse motor 8, and the reagent generates liquid flow inside the reagent auxiliary pipe 102 and is ejected through the injection hole 104. During this process, the reagent auxiliary pipe 102 can be used as a stirrer.

[0042] Furthermore, a plurality of stirring blades 105 are radially arranged on the outer wall of the nozzle tube 103. By adopting the above technology, the stirring is uniform.

[0043] Considering that during rotation, the reagent tube 102, filled with reagent, exerts a certain amount of pressure on it, resulting in unstable rotation and wear. Therefore, a rotation support assembly is also included, comprising an annular guide groove of predetermined size provided on the inner wall of the reaction chamber 1, with an annular ring gear 106 fixed therein. Furthermore, a rotatable support gear 107 is mounted at the end of the reagent tube 102, extending through the annular guide groove and engaging therewith.

[0044] The reagent sub-tube 102 is effectively supported by the meshing support gear 107 and the annular gear ring 106 .

[0045] In another embodiment, the auxiliary cleaning assembly includes: two groups of positioning frames 201 symmetrically mounted on the filter screen 5, and a movable frame 202 is slidably mounted on each group of positioning frames 201. In other words, one end of the movable frame 202 is slidably mounted on the corresponding positioning frame 201, and the other end is connected to a rack 203. The two ends of the rack 203 are elastically connected to the filter chamber 3. The bottom surface of the movable frame 202 is connected to a scraper 204, the purpose of the scraper 204 is to scrape the sludge on the filter screen 5 to both sides, so that the sludge slides through the inclined filter portion 502 into the sludge recovery chamber 6. In order to reduce the wear on the filter screen 5, the bottom of the scraper 204 is a comb tooth structure.

[0046] Furthermore, a rotating gear 205 is mounted on the rotating shaft 9, and the rotating gear 205 is located between the two racks 203 and meshes with each other. Therefore, under the action of the rotating gear 205, the two racks 203 do a relative reciprocating motion, that is, the movement of the scraper 204 is realized.

[0047] Furthermore, both ends of the rack 203 are connected to the filter cavity 3 via at least two sets of springs 206 and guide posts 207 .

[0048] It should be noted that a partition is provided between the reaction chamber 1 and the filtration chamber 3 in this embodiment, and an electric valve is provided on the partition. When filtering treatment is required, the electric valve is controlled to open so that the reaction chamber 1 and the filtration chamber 3 are connected.
