Description

Technical Field

[0001] The invention belongs to the field of water treatment, and in particular relates to a belt-type biological filtering and phytoplankton removal device. Background Art

[0002] Algal bloom, also known as eutrophication or water bloom phenomenon, refers to the phenomenon that certain algae (especially cyanobacteria) or phytoplankton in water bodies over-reproduce, grow rapidly and form large floating algae colonies on the water surface in an environment rich in nutrient substances, especially when rich in nutrients such as nitrogen and phosphorus.

[0003] The existence of algal blooms can cause water quality deterioration, water color changes, water toxicity, destruction of ecological balance, and impact on human use of water resources. Among them, the ecological harm caused by cyanobacteria blooms is particularly serious.

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0040] Example 1

[0041] like Figure 1 As shown, the belt-type biological filter feeding floating algae removal device comprises:

[0042] Rope body 10;

[0043] A plurality of floats 20 are arranged on the rope body 10, and the floats 20 control the device to float in the water body;

[0044] A plurality of biological chambers 30 are arranged on the rope body 10, wherein filter-feeding organisms are arranged inside the biological chambers 30, and the biological chambers 30 are connected to the external water body; wherein the filter-feeding organisms are mainly clams (river clams, toothless clams, triangular sail clams, pleated crown clams, dome pearl clams, back-tumored clams, purple heel split clams, etc.), and river clams, Chinese round field snails, pear-shaped ring-edge snails, etc. are used as supplements according to the released water area;

[0045] The collecting chamber 40 is arranged at the lower end of the biological chamber 30 , and the upper end of the collecting chamber 40 is connected with the lower end of the biological chamber 30 .

[0046] In the technical solution of the belt-type biological filter-feeding and phytoplankton removal device, a float 20 is provided to control the device to float in the water body, a rope body 10 is provided to connect multiple floats 20 and a biological bin 30 to form a whole, and filter-feeding organisms are placed inside the biological bin 30, and the phytoplankton enters the biological bin 30 and is preyed upon by the filter-feeding organisms, and the excrement and pseudo-feces of the filter-feeding organisms enter the collection bin 40, and the pseudo-feces are algae clusters formed by the filtration of blue algae that are difficult for the filter-feeding organisms to digest and utilize in the form of pseudo-feces;

[0047] The belt-type biological filter-feeding floating algae removal device in the present technical solution is suitable for nearshore areas where algae blooms accumulate due to water flow, wind or other reasons. It utilizes the diversity of aquatic organisms and uses filter-feeding organisms to filter tiny particles, plankton, organic matter, etc. in the water, so that nutrients such as nitrogen and phosphorus in the water are separated from the water, thereby changing the nutritional environment of the water and controlling the occurrence of blue algae blooms. The blue algae that are difficult to digest and utilize by filter-feeding organisms can be aggregated into algae clusters in the form of pseudo-feces through filtering, and the pseudo-feces and excrement of the filter-feeding organisms are deposited in a collection bin under the action of gravity. By regularly collecting the concentrated algae in the collection bin, the purpose of reducing the amount of algae in the water is achieved, thereby fundamentally solving the problem of algae blooms.

[0048] like Figure 1 , Figure 2 As shown, the biological chamber 30 includes a shell 31 with an opening at the upper end, and an upper cover 33 arranged at the upper end of the shell 31, a hole 311 is opened on the side wall and the bottom of the shell 31, a hole 331 is opened on the upper cover 33, a filter 32 covering the hole 311 is arranged on the shell 31, and a filter 34 covering the hole 331 is arranged on the upper cover 33; the filter 32 and the filter 34 can be made of nylon mesh with a mesh diameter of 1mm-1cm.

[0049] In the biological bin 30, the shell 1 31 is a supporting frame, and the filter screen 1 32 and the filter screen 2 34 form a filter bin. The filter-feeding organisms enter the interior of the filter bin through the upper end opening of the shell 1 31, and the floating algae enter the interior of the filter bin through the hole 1 311 and the filter screen 1 32, the hole 2 331 and the filter screen 2 34, and are preyed upon by the filter-feeding organisms.

[0050] like Figure 2 As shown, threaded sections are provided on the upper outer wall of the shell 31 and the inner wall of the upper cover 33, and the shell 31 and the upper cover 33 are threadedly matched; the biological bin 30 and the upper cover 33 are connected by threaded matching, and the biological bin 30 and the upper cover 33 are easy to install and disassemble, which makes it convenient to place the filter-feeding organisms into the biological bin 30 or take them out of the biological bin 30.

[0051] like Figure 2 As shown, the collecting bin 40 comprises a shell 2 41 with an opening at the upper end, the bottom of the biological bin 30 is located in the opening of the shell 2 41, and the collecting bin 40 and the biological bin 30 are connected through a hole 1 311; the lower end of the shell 2 41 is provided with a discharge pipe 43, and a valve 44 is provided on the discharge pipe 43, and the valve 44 is a rust-proof copper ball valve; the shell 2 41 is provided with a hole 3 411, and the shell 2 41 is provided with a filter 3 42 covering the hole 3 411, and the filter 3 42 is a 200-mesh anti-corrosion mesh.

[0052] In the collecting bin 40, the shell 2 41 is a supporting frame, and the filter 3 42 is a pseudo-feces and excrement collecting part; the excrements and pseudo-feces produced by the filter-feeding organisms enter the interior of the collecting bin 40 through the hole 1 311 for collection, and after a certain period of time, the valve 44 is opened, and the excrements and pseudo-feces are discharged from the discharge pipe 43 and collected.

[0053] like Figure 2 As shown, a threaded section is provided on the lower end outer wall of the shell 1 31 and the inner wall of the shell 2 41 , and the lower end outer wall of the shell 1 31 and the shell 2 41 are threadedly matched.

[0054] The biological bin 30 and the collection bin 40 are connected by means of threaded cooperation between the lower end outer wall of the shell 1 31 and the shell 2 41 . The biological bin 30 and the collection bin 40 are easy to install and disassemble, and it is convenient to clean the inside of the collection bin 40 .

[0055] Since the floating algae are light in weight and mostly float on the water surface or the upper part of the water body, in order to ensure the survival of the filter-feeding organisms in the biological chamber 30, the biological chamber 30 is usually set below the water surface, so that the filter-feeding organisms have a smaller prey range. Figure 1 , Figure 3 As shown, the belt-type biological filtering and phytoplankton algae removal device is additionally provided with a disturbance mechanism 50; the disturbance mechanism 50 includes a rotatably arranged long shaft 54, the long shaft 54 ​​is connected to a side rod 510 through a connecting piece, and a filter screen 511 is arranged between the long shaft 54 ​​and the side rod 510.

[0056] like Figure 4 As shown, the long axis 54 drives the side rod 510 and the filter screen four 511 to rotate, and the filter screen four 511 circulates in and out of the water surface and the water body in turn, disturbing the water body, and at the same time drives the phytoplankton floating on the water surface or the upper part of the water body to move downward, thereby increasing the distribution range of the phytoplankton and improving the predation effect of filter feeders; the spoiler adopts the setting of the filter screen four 511 to drive the phytoplankton to move, and at the same time filter out the water, thereby reducing the resistance required for entering the water and rotating in the water.

[0057] like Figure 3 As shown, the connecting part includes a sleeve 59 connected to the long axis 54 and a long rod 57 connected to the side rod 510. One end of the long rod 57 is inserted into the interior of the sleeve 59 and slidably cooperates with it. A spring 58 is sleeved on one end of the long rod 57 located inside the sleeve 59 and is connected to an armature 56. The two ends of the spring 58 are respectively connected to the sleeve 59 and the armature 56. An electromagnet 55 is provided on one side of the armature 56.

[0058] When the electromagnet 55 is energized, the magnetic force generated attracts the armature 56 to drive the long rod 57 and the side rod 510 to move in the direction of the long axis 54, and the filter four 511 is in a retracted state. When the electromagnet 55 is de-energized, the spring 58 drives the long rod 57 and the side rod 510 to move in the direction away from the long axis 54, and the filter four 511 is in an expanded state.

[0059] The combined structure of the connecting piece, the side rod 510 and the filter four 511 is such that the filter four 511 is in an expanded state when on the water surface and before entering the water at 90-120 degrees, and is in a contracted state after entering the water at 90-120 degrees and before exiting the water; when the filter four 511 is in the expanded state, it drives the phytoplankton to move, and when the filter four 511 is in the contracted state, it no longer controls the movement of the phytoplankton to avoid bringing the phytoplankton out of the water surface, and after driving the phytoplankton into the water for a certain distance, it is no longer manipulated to ensure that the phytoplankton maintains a downward movement trend as a whole, thereby ensuring the predation effect of filter-feeding organisms.

[0060] To solve the rotation setting requirements of the long shaft 54, such as Figure 3 As shown, the spoiler mechanism 50 also includes a servo motor 51, an installation cavity 21 is opened inside the float 20, the servo motor 51 is installed inside the installation cavity 21, the output end of the servo motor 51 is connected to a gear 1 52, and the gear 1 52 is meshed with a gear 2 53; one end of the long shaft 54 ​​extends to the inside of the installation cavity 21 and cooperates with the mechanical seal of the side wall of the installation cavity 21, and the gear 2 53 is sleeved on the long shaft 54.

[0061] The servo motor 51 is powered on to drive the gear 1 52 to rotate, and the gear 1 52 is meshed with the gear 2 53 to drive the long shaft 54 ​​to rotate synchronously; wherein the servo motor 51 can drive the long shaft 54 ​​to rotate alternately in the forward or reverse direction, and the rotation direction is as follows: Figure 4 As shown by the arrow in , the spoiler effect of the spoiler mechanism 50 is increased.

[0062] like Figure 3 As shown, a groove 541 is provided inside one end of the long shaft 54 ​​on which the gear 2 53 is assembled, and the electromagnet 55 is assembled in the groove 541, wherein the battery for powering the electromagnet 55 and the control component for controlling whether the electromagnet 55 is powered can be installed inside the installation cavity 21, and the cable on the electromagnet 55 can be connected to the battery and the control component through the groove 541. The sealing cooperation between the long shaft 54 ​​and the installation cavity 21, and the sealing cooperation between the long rod 57 and the sleeve 59 prevent water from entering the interior of the installation cavity 21, thereby ensuring the safe use of electricity for the servo motor 51 and the electromagnet 55. A groove 2 542 is provided on the side wall of the groove 541 corresponding to the position of the electromagnet 55, thereby improving the attraction of the electromagnet 55 to the armature 56.

[0063] Because the belt-type biological filter feeding and phytoplankton algae removal device in the present technical solution is arranged inside the water body, when the water flows, especially after the disturbance mechanism 50 is added, the water flow will drive the biological bin 30 and the collection bin 40 to move. In order to avoid the biological bin 30 and the collection bin 40 affecting the operation of the disturbance mechanism 50, as shown in FIG. Figure 1 , Figure 2 As shown, the upper end of the housing 1 31 is configured to be an arc convex upward.

[0064] When the combined structure of the long axis 54, the side rod 510 and the filter screen four 511 rotates, if there is a contact with the upper end of the biological bin 30, because the upper end of the shell 1 31 is configured to be an upwardly convex arc, the biological bin 30 is subjected to the force and deflects and retreats as a whole; at the same time, the biological bin 30 can be deflected to increase the position range of the biological bin 30, increase the feeding range of the filter-feeding organisms inside the biological bin 30, and improve the effect of removing floating algae.

[0065] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
