Detailed ways

Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

As shown in Figures 1 and 2, the present invention includes an algae removal device A and an algae removal device B. The center opening of the bottom of the algae removal device A is threaded on the algae removal device B; the algae removal device A includes an algae removal device Outer bucket 17, except the duckweed outer bucket 17 upper edge is sleeved with the ring-shaped barrier 13 that communicates with waters, the top opening of barrier 13 is sealed with top cover 15, and the top cover 15 top is equipped with the motor 6 that drives blade 14 except duckweed , the inner bottom surface of the top cover 15 is fixed with a cylindrical retaining ring 16 with a depth smaller than that of the barrel 17 except for the flattened surface, and a blade 14 is arranged inside the cylindrical retaining ring 16;

As shown in Fig. 3 and Fig. 4, described algae removal device B comprises algae removal outer barrel 7, and algae removal outer barrel 7 is provided with rough filter screen 3 along the water inlet of side wall, and the top mouth sealing of algae removal outer barrel 7 There is an algae removal device top cover 2, and a filter barrel 4 with a stainless steel filter screen is arranged concentrically inside the algae removal outer barrel 7; the center of the bottom of the algae removal outer barrel 7 is connected with a clean water pipe 12, and the mouth of the clean water pipe 12 is equipped with a fine filter screen 8; The bottom surface between the filter bucket 4 and the bucket 7 for removing algae is connected with an algae liquid pipe 9 .

As shown in Figure 1, the present invention is divided into upper and lower two parts, and the upper part is the weed removal device A, and the lower part is the algae removal device B. In the duckweed removing device A, the part between the cylindrical retaining ring 16 and the duckweed removing barrel 17 is the algae weed mixing zone I, and the blade 14 is used inside the cylindrical retaining ring 16 to form the algae weeding zone II, and the duckweed is mixed with the water from the algae weed Area I falls into the bottom of the weed removal device A, under the action of buoyancy, the duckweed floats up, reaches the blade 14 and is chopped, and the blade 14 is driven by the weed removal motor 6 . In the algae removal device B, the upper port inserted in the algae removal device A is the water intake area III of the algae removal device, the algae liquid area IV is formed between the filter barrel 4 and the algae removal outer barrel 7, and the inside of the filter barrel 4 is the clear water area V. Under the action of water flow, the chopped duckweed and algae liquid are washed from the water inlet area III of the algae removal device into the algae liquid area IV of the algae removal device, filtered through the filter barrel 4, and the clean water enters the inside of the filter barrel 4 as the clean water area V. The clear water pipe 12 and the algae liquid pipe 9 connected to the outer barrel 7 bottom surface are used to discharge clear water and concentrate the algae liquid respectively. The clean water pipe 12 and the algae liquid pipe 9 are all controlled by solenoid valves, and the opening and closing of the solenoid valves are controlled by water pressure and gravity, and the first water pump 10 and the second water pump 11 are utilized to generate negative pressure to discharge the algae liquid or clear water.

As shown in Figure 3 and Figure 4, the filter barrel 4 is used to filter the raw liquid sucked into the algae removal device B by the second water pump 11, and a backwash pump 5 is built in the filter barrel 4, and the opening time of the backwash pump 5 will be preset in advance Well, clean the filter barrel regularly to prevent algae from accumulating and multiplying in the filter barrel, which will reduce the filtering effect. Coarse filter screen 3 blocks objects that cannot be filtered such as bulk garbage out of the algae-removing outer bucket. The backwash pump 5 is fixed by a bracket in the filter bucket 4 .

The working principle of the present invention is: the present invention is placed in a suitable position of the water body, and the pressure of the water is used to form a funnel area to attract the nearby liquid, and the liquid will automatically enter into the bucket 17 for removing duckweed and algae nearby. stand up. After being treated by the algae removal device A, the liquid first enters the algae liquid area IV of the algae removal outer barrel 7, and the second water pump 11 connected to the clear water pipe makes the liquid flow to the central area of the filter barrel 4, thereby implementing filtration. A commonly used second water pump 11 is a fountain pump. The filtered algae stay in the algae liquid area IV, and the clear water returns to the original water body through the clean water pipe. The interval time for opening the first water pump 10 of the algae liquid pipe 9 is determined according to the flow rate, and is controlled by a microcomputer time control switch. The concentrated algae liquid is extracted, and then the algae liquid is subjected to subsequent treatment. Regularly open the backwash pump 5 to clean up the algae remaining in the filter barrel 4 in time to improve the work effect.

The invention uses the physical principle to inhale the algae liquid, and leaves the concentrated algae suspension inside the device. The structure is simple and easy to operate. In artificial lakes with fountains, fountain pumps can also be used to connect clean water pipes to reduce the number of pumps and reduce the consumption of electric energy. . The vast majority of algae clusters and large single algae are removed by physical algae removal, while secondary pollution by chemical algae removal is avoided.

In the present invention, on the water surface with duckweed, weed removal device A is screwed to the height of the water entry area of algae removal device B through rotation, and weed removal device A quickly stirs and crushes duckweed, so that the small duckweed and algae flow into the algae removal together The algae liquid area of device B, because the duckweed fragment size is smaller than the rough filter screen 3, larger than the aperture of the filter bucket 4, it can be drawn out by the algae liquid pipe 9, and is connected with the algae treatment device on the bank by the algae liquid pipe. When the algae are taken away from the lake, a large amount of P and N are also taken away, so as to achieve our goal of controlling the eutrophication of the water body. The invention has multifunctional purposes and is suitable for removing algae on the lake surface.
