Description

Technical Field

[0001] The utility model relates to the field of water treatment equipment, in particular to an integrated flocculation air flotation ultrafiltration water purification equipment. Background Technique

[0002] In the field of water treatment, in order to remove suspended solids or impurities in water, flocculation and air flotation are usually used to filter water. However, traditional flocculation and air flotation methods will add a large amount of chemical agents to the water. Although the use of chemical agents for water purification has a good purification effect, some chemical agents will remain in the water, and manual addition is required. If the worker is slightly careless, they will be harmed by the chemical agents. Therefore, in order to avoid the above problems, water treatment plants use the method of electrocoagulation air flotation for water treatment. Therefore, an integrated flocculation air flotation ultrafiltration water purification equipment is needed to solve the above problems.

[0003] Chinese Patent No. CN216106366U discloses an air flotation flocculation component of an integrated water purification equipment. A partition is fixedly installed inside a sewage treatment tank. The water treatment tank is divided into a flocculation area and a water purification area by the partition. A flocculant filter screen is fixedly installed inside the flocculation area. A sewage collection box is arranged above the flocculant filter screen. The sewage collection box is a rectangular hollow structure. Two installation grooves are opened on the left and right side walls of the sewage collection box. The two installation grooves are distributed up and down on the side wall of the sewage collection box. Two telescopic rods are arranged at the positions corresponding to the left and right sides of the sewage collection box and the installation grooves. A fixing block for connecting the sewage collection box and the telescopic rod is arranged between the installation groove and the telescopic rod. The fixing blocks are fixedly connected to the inner wall of the installation groove and the end of the telescopic rod respectively. A scraper is fixedly installed below the outer wall of the sewage collection box. The scraper is a cylindrical structure with a triangular cross-section. The triangular cross-section of the scraper reduces the contact area between the scraper and the flocculant, enhancing the descaling ability of the scraper.

[0004] After the actual use of this patent, the sundries in the water treated by electrocoagulation air flotation will float on the upper surface of the water due to different densities. During water treatment, workers need to continuously scoop out the suspended solids or impurities on the upper layer, which is time-consuming and laborious. Moreover, the operation of replacing the flocculation plate in this patent is complicated and inconvenient for maintenance. Content of the Utility Model

[0022] According to Figure 1As shown in the figure, the integrated flocculation, air flotation and ultrafiltration water purification equipment includes a flocculation device 1 and an air flotation device 2. The flocculation device 1 is arranged on one side of the air flotation device 2. The flocculation device 1 and the air flotation device 2 are connected through a connecting pipe 3. A flocculation area is provided at the top of the flocculation device 1. A plurality of flocculation plates 4 are arranged in the flocculation area. The flocculation plates 4 are movably clamped on the inner wall of the flocculation area through a buckle assembly 41. A first water pump 8 is fixedly arranged on one side of the flocculation device 1. A second water pump 81 is fixedly arranged on one side of the air flotation device 2. An air flotation area is provided at the top of the air flotation device 2. A return frame 6 is rotatably arranged on one side of the top of the air flotation device 2. A cleaning assembly 7 is slidably arranged in the return frame 6. An aerator 9 is arranged on one side of the air flotation device 2. A drain port is provided on one side of the flocculation device 1. One end of the connecting pipe 3 is communicated with the drain port, and the other end is communicated with the water inlet of the second water pump 81.

[0023] In specific implementation, the flocculation device 1 is arranged on one side of the air flotation device 2. The water source to be treated is transported to the flocculation area of the flocculation device 1 through the first water pump 8. The flocculants are filtered through the plurality of flocculation plates 4 arranged in the flocculation area. Each flocculation plate 4 is movably installed in the flocculation area through the buckle assembly 41. The movably installed flocculation plates 4 are not only convenient for quickly replacing and cleaning the flocculation plates 4, but also convenient for adjusting the filtration times according to the total amount of water treatment, so as to adjust the filtration times according to different water sources and water volumes, reducing the cost of the enterprise. The air flotation device 2 transports the filtered water to the air flotation area through the second water pump 81 and the connecting pipe 3. The aeration volume of the water is increased through the aerator 9. After the water is aerated, the suspended substances and impurities doped in it float on the upper surface of the water. The cleaning assembly 7 is continuously moved left and right on the upper surface of the water to clean the suspended substances and impurities floating on the upper surface of the water.

[0024] According to Figure 2 and Figure 4 As shown in the figure, the buckle assembly 41 includes a contraction groove 411, a clamping block 413 and a plurality of mounting holes 42. The plurality of mounting holes 42 are all opened on the inner walls on both sides of the flocculation area. The contraction groove 411 is opened at both ends on both sides of the flocculation plate 4. An activity groove 412 is opened in the contraction groove 411 in the direction towards the upper surface of the flocculation plate 4. The clamping block 413 is slidably arranged in the contraction groove 411, and the front end of the clamping block 413 is movably clamped in the mounting hole 42. A plate 414 is slidably arranged in the activity groove 412. The plate 414 is fixedly connected with the clamping block 413. A return spring 415 is fixedly arranged between the clamping block 413 and the contraction groove 411. A cover plate 5 is rotatably arranged on one side of the top of the flocculation device 1.

[0025] In specific implementation, by moving the plate 414 towards the inner side plate, the plate 414 slides within the movable slot 412. While the plate 414 slides, it drives the latch 413 slidably arranged within the contraction slot 411 to move towards the inside of the contraction slot 411. While moving, the front end of the latch 413 slides out from the mounting hole 42, thereby taking out the flocculation plate 4 from the flocculation device 1. Conversely, during installation, the plate 414 is moved again to make the slider 73 contract towards the inside of the contraction slot 411. After contraction, the contraction slot 411 of the flocculation plate 4 is aligned with the mounting hole 42. The plate 414 is released, and the reset spring 415 is used to move the latch 413 into and out of the mounting hole 42 to install the flocculation plate 4.

[0026] According to Figure 3 As shown, the cleaning assembly 7 includes a linear slide bar 71, a threaded rod 72, a slider 73, and a collection box 77. Two linear slide bars 71 can be provided. The two linear slide bars 71 are arranged in parallel within the rectangular frame 6. The threaded rod 72 is rotatably arranged between the two linear slide bars 71 within the rectangular frame 6. Through holes 732 are respectively formed at both ends on both sides of the slider 73. A threaded hole 731 is formed between the through holes 732. The slider 73 is slidably arranged on the linear slide bar 71 through the through holes 732 and is rotatably arranged on the threaded rod 72 through the threaded hole 731. A servo motor 74 is fixedly arranged on one side of the rectangular frame 6. The output end of the servo motor 74 passes through the rectangular frame 6 and is fixedly connected to one end of the threaded rod 72. A negative pressure water pump 75 is fixedly installed at the bottom of the slider 73. The collection box 77 is fixedly arranged at the rear side of the flotation device 2. The collection box 77 is communicated with the negative pressure water pump 75 through a collection pipe 78; an L-shaped aeration pipe 91 is arranged within the flotation area. One end of the aeration pipe 91 is communicated with the aerator 9; a motor placement groove 741 is formed at one side of the top of the flotation device 2; a collection plate 76 is obliquely arranged at the water inlet end of the negative pressure water pump 75.

[0027] In specific implementation, the rectangular frame 6 is horizontally placed on the flotation device 2, and the cleaning assembly 7 is made to fit the upper surface of the water. Two linear slide bars 71 are provided. The two linear slide bars 71 restrict the moving direction of the slider 73, improving the moving stability of the slider 73. The servo motor 74 controls the forward or reverse rotation of the threaded rod 72, causing the slider 73 rotatably arranged on the threaded rod 72 to move left or right according to the rotation direction of the threaded rod 72. While the slider 73 moves left and right, the negative pressure water pump 75 can pump the suspended substances and impurities floating on the water surface into the collection box 77 for collection, eliminating the need for manual scooping and improving the water treatment efficiency. The collection plate 76 and the liquid inlet of the negative pressure water pump 75 can be fixedly arranged at a 45° angle. The obliquely arranged collection plate 76 facilitates the transportation of the suspended substances and impurities into the negative pressure water pump 75. The motor placement groove 741 can provide a placement space for the servo motor 74 when the rectangular frame 6 is horizontally placed on the flotation device 2. The aerator 9 can increase the amount of aeration in the water during water treatment.
