Description

Technical Field

[0001] This invention relates to the field of water sieving technology in environmental protection, specifically a gill filter. Background Technology

[0002] When lake water is severely polluted by organic matter, with excessive nitrogen and phosphorus levels, and in a state of eutrophication, algae can proliferate explosively when suitable temperatures are present. This algal bloom not only affects the aquatic landscape and the normal production of aquatic products, but the toxins released from ruptured algal cells also pose a significant threat to human health. Particularly serious is the excessive algal growth in rivers and lakes used as drinking water sources, which leads to the deterioration of drinking water quality, increasing the difficulty and cost of water treatment at water plants.

[0003] In this scenario, if an algal bloom occurs, the water body needs to be treated, specifically by separating the algae for other uses. However, existing algae separation equipment has several drawbacks: firstly, its separation capacity is low, and achieving better separation capacity requires investing in better equipment, leading to a significant increase in separation costs, which is not conducive to widespread adoption; secondly, existing equipment is prone to clogging, requiring shutdown and maintenance after a period of use, which is obviously detrimental to separation efficiency.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] In order to improve the efficiency of algae water sieving and reduce the cost of sieving, this application provides Embodiment 1, which is a preferred solution for a gill filter.

[0037] Specifically, such as Figure 1 The sieving device includes a frame 1, which serves as a support structure, and a filter screen 2, which is mounted on the frame 1 and used to filter water. The filtered water flows to the bottom of the filter screen 2, while the filtered residual algae remain above the filter screen 2, thus achieving the function of algae and water sieving.

[0038] Furthermore, to improve screening efficiency and ensure that the algae-infused water covers the filter screen 2 as much as possible, such as... Figure 1 The sieving device also includes a water distribution component 3, which is placed above the filter screen 2 to distribute the water to be filtered on the filter screen 2 and at the same time make the amount of water passing through the filter screen 2 uniform.

[0039] Furthermore, such as Figures 1-3The water distribution component 3 specifically includes several water distribution pipes 31, which are distributed along the transverse direction of the filter screen 2. Each water distribution pipe 31 extends along the longitudinal direction of the filter screen 2. Each water distribution pipe 31 includes an inlet 312 and several water distribution holes 311. The inlet 312 is opened at the end of the water distribution pipe 31 for introducing the water to be filtered. The several water distribution holes 311 are distributed along the extension direction of the water distribution pipe 31 and face the filter screen 2, so that the algae water is sprayed onto the filter screen 2 through the water distribution holes 311 on the water distribution pipe 31. The water distribution holes 311 trap larger waste in the water distribution pipe 31, improving the uniform water distribution while preventing larger waste from clogging the filter screen 2.

[0040] Furthermore, such as Figure 1 The water distribution component 3 also includes a sealing head 313, which is located at the end of the water distribution pipe 31 away from the water inlet 312. It is used to seal the end of the water distribution pipe 31 away from the water inlet 312. Furthermore, after the water distribution pipe 31 has been running for a period of time, large waste will block the water distribution pipe 31. The sealing head 313 makes it convenient to clean the water distribution pipe 31.

[0041] Furthermore, to prevent filter screen 2 from becoming clogged by algae and bacteria after prolonged operation, its surface needs to be cleaned to ensure its sustainable operating efficiency. Therefore, as follows... Figure 1 The sieving device also includes a cleaning component 4, which is placed above the filter screen 2 and is used to spray water to clean the filter screen 2, thereby preventing the filter screen 2 from clogging.

[0042] Furthermore, cleaning the filter screen 2 using the cleaning component 4 requires clean water. If an external water source is used, it would result in resource waste and increased equipment costs. Therefore, it is considered to use the water filtered by the filter screen 2 to clean the screen itself, thereby improving resource utilization and reducing operating costs. Based on this, such as... Figures 1-2 The sieving device also includes a collection tank 5 and a pump body 6. The collection tank 5 is placed below the filter screen 2 and is used to collect the filtered water. The collection tank 5 includes a guide plate 51. When the water in the collection tank 5 overflows, the water is discharged from the collection tank 5 along the guide plate 51. The pump body 6 is placed in the collection tank 5 and its output end is connected to the input end of the cleaning component 4. It is used to pump the water in the collection tank 5 into the cleaning component 4. In this embodiment, the pump body 6 is preferably a high-pressure pump. The collection tank 5 has a water storage function to facilitate the use of the high-pressure pump. At the same time, the guide plate 51 guides the remaining water to flow out. The high-pressure pump pumps the water into the cleaning component 4 to clean the filter screen 2.

[0043] Furthermore, such as Figure 1The cleaning component 4 is specifically configured as follows: it includes a pipe 41, which is placed above the filter screen 2 and extends along the transverse direction of the filter screen 2, with one end of the pipe 41 connected to the output end of the pump body 6; it also includes several nozzles 42, which are arranged along the extension direction of the pipe 41 and whose input ends are connected to the pipe 41. The nozzles 42 are also spaced apart from several water distribution pipes 31, so that the nozzles 42 can extend as far as possible toward the filter screen 2.

[0044] Furthermore, the cleaning component 4, even with this configuration, cannot provide complete coverage of the filter screen 2, thus failing to achieve a thorough cleaning effect. Figure 1 The filtration device also includes a power component 7 for driving the cleaning component 4 to move along the longitudinal direction of the filter screen 2, that is, the power component 7 drives the cleaning component 4 to achieve full coverage of the filter screen 2.

[0045] Furthermore, such as Figure 1 The power assembly 7 specifically includes a power source 71, preferably a stepper motor, for providing rotational load; it also includes a rotating wheel 72 and a driven wheel 73, the rotating wheel 72 being connected to the output end of the power source 71, the rotating wheel 72 and the driven wheel 73 being rotatably arranged relative to the frame 1, and the rotating wheel 72 and the driven wheel 73 being located above the two ends of the filter screen 2 in the longitudinal direction; it also includes a conveyor belt 74, the conveyor belt 74 being tensioned or engaged between the rotating wheel 72 and the driven wheel 73, and the middle part of the conveyor belt 74 being connected to the pipe 41; in this way, the rotational load can be transmitted to the conveyor belt 74 through the rotating wheel 72, thereby driving the pipe 41 to move along the longitudinal direction of the filter screen 2, thereby achieving a comprehensive cleaning of the filter screen 2.

[0046] In this device, the automatic cleaning method of filter screen 2 and cleaning component 4 can significantly improve the screening efficiency. Experiments have shown that the screening efficiency of this device can reach 150m³ / h, and the algae content of the screened algae slurry is significantly improved, which is equivalent to the combined effect of gill filter and stacked shaking thickening screen. Moreover, this device is not easy to clog and does not require shutdown for cleaning, further improving the screening efficiency.

[0047] Furthermore, in order to ensure that the pipe fitting 41 moves smoothly along the longitudinal direction of the filter screen 2, it is also necessary to guide the pipe fitting 41. Based on this, such as Figure 1 The power assembly 7 also includes a connecting rod 75 that extends in the transverse direction of the filter screen 2 and connects the conveyor belt 74 to the pipe 41; and at least two guide assemblies 76. In this embodiment, the guide assemblies 76 are preferably two, corresponding to the two ends of the pipe 41 respectively.

[0048] Furthermore, such as Figure 1The guiding component 76 specifically includes a fixed base 761, a guide rod 762, and a slider 763. The guide rod 762 extends along the longitudinal direction of the filter screen 2 and is connected to the frame 1 through the fixed base 761. The slider 763 is sleeved on the guide rod 762. At the same time, the sliders 763 of the two guiding components 76 are respectively connected to the two ends of the connecting rod 75. When the connecting rod 75 is moved by the conveyor belt 74, the slider 763 also moves along the guide rod 762, thereby restricting the displacement of the water distribution pipe 31.

[0049] Furthermore, such as Figure 1 The guide component 76 also includes a limit switch 764, which is mounted on the fixed base 761 and is used to control the reciprocating displacement of the water distribution pipe 31.

[0050] Furthermore, such as Figure 1 The sieving device also includes an upper cover 8, which is hinged to the top of the frame 1 and closes during operation to provide protection and dust prevention.

[0051] Furthermore, such as Figure 1 The specific frame 1 includes: a first frame 11, on which the collection tank 5 is fixedly mounted; a second frame 12, which is located above the first frame 11, fixedly mounted with the first frame 11, and inclined relative to the first frame 11, with the filter screen 2 placed on the second frame 12, i.e., the filter screen 2 is placed at an incline to facilitate the discharge of water and algae; and a third frame 13, which is located above the second frame 12 and hinged to the second frame 12, with the water distribution component 3, the cleaning component 4, and the power component 7 all mounted on the third frame 13. The hinged second frame 12 and third frame 13 can separate the water distribution component 3, the cleaning component 4, the power component 7 from the filter screen 2, facilitating the maintenance and replacement of the filter screen 2.

[0052] Furthermore, such as Figure 1 The frame 1 also includes a support rod 14 and a support 15. The support 15 is placed on the second frame 12 and the third frame 13. When the support rod 14 is connected to the support 15, the second frame 12 and the third frame 13 form an angle, thereby fixing the open state of the second frame 12 and the third frame 13 to facilitate the replacement of the filter screen 2.

[0053] Furthermore, such as Figure 1 The frame 1 also includes a limiting block 16, which is placed on the side of the second frame 12 near the third frame 13. When the second frame 12 and the third frame 13 are closed, the limiting block 16 acts as a buffer to prevent collision between them.

[0054] Furthermore, such as Figure 1The frame 1 also includes a guide channel 17, which is placed on the first frame 11 and located below the end of the filter screen 2, for guiding and collecting the screened algae.

[0055] In cases where large-scale treatment of algae-infused water is required, this application also provides Embodiment 2, which involves vertically stacking the sieving devices disclosed in Embodiment 1 to improve sieving capacity.
