[0002] The high-flow-rate vertical microfiltration device for algae-water separation is a highly efficient core equipment for water treatment, specifically designed to address algal bloom pollution in large-scale water bodies (such as lakes, reservoirs, and water treatment plants). Algae-infused water passes through the filter screen, while algae, suspended solids, and other particulate impurities are trapped on the screen surface. This high-flow-rate vertical microfiltration device is a key technological tool for the treatment of eutrophic water bodies and for pretreatment in water treatment plants.
[0003] The existing high-flow vertical microfiltration devices for algae-water separation have the following shortcomings when in use. In order to ensure the filtration effect of the microfiltration device, it is necessary to clean the algae residue and other impurities on the filter screen regularly. Most existing microfiltration devices only use the movement of brushes to clean the algae residue. The brushes can only clean the surface of the filter screen and have zero cleaning efficiency for the filter pores on the filter screen, which leads to clogging of the microfiltration device and affects the algae-water separation effect.
[0004] Therefore, those skilled in the art have proposed a high-flow-rate vertical microfiltration device for algae-water separation to solve the aforementioned problems. Utility Model Content

[0029] Example 1
[0030] Reference Figure 1 , Figure 3 and Figure 4 This is the first embodiment of the present invention, which provides a high-flow-rate vertical microfiltration device for algae-water separation, which can improve the cleaning effect of the microfiltration device, including:
[0031] Microfiltration treatment box 100, a motor 103 is installed on the microfiltration treatment box 100, the output end of the motor 103 is connected to a rotating hollow frame 104, and the outer wall of the rotating hollow frame 104 is covered with a microporous filter cloth 105, which is used for microfiltration treatment of algae-water separation.
[0032] It should be noted that the electrical terminals of each electrical device are electrically connected to the power supply and the controller (installed on the outer wall of the microfiltration treatment box 100) via wires. The microporous filter cloth 105 is used to separate impurities in the algae water, so that the algae residue remains on the surface of the microporous filter cloth 105.
[0033] The backwashing unit 200 includes a backwashing pipe 212 located inside the rotating hollow frame 104, and multiple sets of nozzles 213 are installed on the backwashing pipe 212. The inner wall of the microfiltration treatment box 100 is provided with two sets of reciprocating plates 210, and each set of reciprocating plates 210 is connected to a cleaning brush 211 for cleaning algae residue on the surface of the microporous filter cloth 105.
[0034] During use, the algae water is filtered, separated, and micro-filtered through the microporous filter cloth 105 fitted on the outer wall of the vertically mounted rotating hollow frame 104. When it is necessary to clean the algae residue on the surface of the microporous filter cloth 105, multiple sets of nozzles 213 on the backwash pipe 212 spray water, which impacts the impurities in the filter pores of the microporous filter cloth 105 and removes the impurities. The reciprocating plate 210 drives the cleaning brush 211 to move up and down, brushing the algae residue on the surface of the microporous filter cloth 105. The combination of these two actions improves the cleaning effect of the microporous filter cloth 105. The operation of the motor 103 drives the rotating hollow frame 104 to rotate, realizing all-round cleaning of the microporous filter cloth 105, avoiding clogging, and improving the separation effect of the microfiltration device on algae water.
[0035] Example 2
[0036] Reference Figures 1 to 4 This is the second embodiment of the present invention. Unlike the previous embodiment, the microfiltration treatment box 100 is equipped with a connected split water inlet pipe 101 for the intake of algae water, and the microfiltration treatment box 100 is provided with a through-hole drain outlet 102; the split water inlet pipe 101 is used for the large flow of algae water to enter, and the drain outlet 102 discharges the separated and microfiltration treated algae water or the cleaned impurities.
[0037] The inner wall of the microfiltration treatment box 100 is fixed with two sets of sealing baffles 106, both sets of sealing baffles 106 are close to the outlet of the split water inlet pipe 101; the sealing baffles 106 play a sealing role, ensuring that all algae water can pass through the microporous filter cloth 105.
[0038] The backwashing unit 200 also includes a clean water pump 201 fixed to the microfiltration treatment box 100. The outlet of the clean water pump 201 is connected to a water supply pipe 202, and the end of the water supply pipe 202 away from the clean water pump 201 is connected to the backwash pipe 212. The water inlet pipe of the clean water pump 201 generates suction to transport clean water to the water supply pipe 202 and the backwash pipe 212. Multiple sets of nozzles 213 then spray clean water to achieve impact cleaning of the filter pores on the microporous filter cloth 105.
[0039] The inner wall of the microfiltration treatment box 100 is fixed with two sets of U-shaped frames 206, and the inner wall of the U-shaped frame 206 is fixed with vertical rods 207. A slide block 208 is slidably connected to the vertical rod 207, and the slide block 208 is fixedly connected to the reciprocating plate 210.
[0040] Among them, the outer wall of the vertical rod 207 is fitted with two sets of springs 209, which are located between the inner wall of the slide 208 and the U-shaped frame 206.
[0041] Two sets of motors 203 are fixed to the outer wall of the microfiltration treatment box 100, and the output end of the motors 203 is connected to the rotating rod 204.
[0042] The rotating rod 204 passes through the microfiltration treatment box 100, and a cam 205 is fixedly connected to the rotating rod 204. The operation of the motor 203 drives the cam 205 on the rotating rod 204 to rotate. Since the slide 208 is elastically slidably mounted on the vertical rod 207 through two sets of springs 209, the cleaning brush bristles 211 on the reciprocating plate 210 can move up and down back and forth, which can rub the algae residue on the microporous filter cloth 105. Combined with the backwashing water spray, the cleaning effect on the microporous filter cloth 105 can be improved.
[0043] During use, the algae water enters the microfiltration treatment box 100 at a high flow rate through the split water inlet pipe 101. Two sets of sealing baffles 106 guide the algae water, causing it to pass through the microporous filter cloth 105 on the vertically rotating hollow frame 104. The microporous filter cloth 105 filters, separates, and microfilters the algae water, leaving algae residue on the surface of the microporous filter cloth 105. The microfiltered algae water is discharged through the drain port 102.
[0044] When cleaning the algae residue on the surface of the microporous filter cloth 105, the clean water pump 201 on the backwash unit 200 operates, delivering clean water through the water supply pipe 202 to the backwash pipe 212. Multiple sets of nozzles 213 spray water, which impacts the impurities in the filter pores of the microporous filter cloth 105, cleaning them out. Two sets of motors 203 operate, causing the cam 205 fixed on the rotating rod 204 to rotate. Since the slide 208 is elastically slidably mounted on the vertical rod 20 by two sets of springs 209, 7. The cleaning brush bristles 211 on the reciprocating plate 210 can move up and down back and forth, which can rub the algae residue on the microporous filter cloth 105. Combined with the backwashing water spray, the cleaning effect of the microporous filter cloth 105 can be improved. The motor 103 drives the rotating hollow frame 104 to rotate, realizing the all-round cleaning of the microporous filter cloth 105. The cleaned algae residue can be discharged through the drain port 102 to avoid clogging of the microporous filter cloth 105 and improve the algae-water separation and microfiltration effect.
[0045] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
[0046] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.
[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
