Abstract
Description
Technical Field
[0001] This utility model relates to the field of cyanobacteria treatment technology, specifically to equipment for emergency treatment of cyanobacteria in lake and reservoir drinking water sources. Background Technology
[0002] Cyanobacterial blooms are the most common type of bloom in freshwater lakes and reservoirs. They are caused by the explosive reproduction of cyanobacteria, which can lead to abnormal water color. Cyanobacterial blooms can cause blockages in water supply systems, unpleasant odors in the water, fish deaths, degradation of aquatic vegetation, and may produce toxins, threatening the safety of drinking water.
[0003] Currently, the harvesting of blue-green algae is often done manually, and then the algae are dried in drying equipment for further use. This method is not only inefficient, but also puts workers under high labor intensity.
[0004] Chinese patent discloses a blue-green algae harvesting, treatment, and recycling machine (authorization announcement number CN221193253U). This patented technology, after enabling the movement of the vessel, utilizes a suction pump, suction pipe, and suction head to draw in blue-green algae from the water. The algae is then discharged into a feeding cylinder through a first feeding pipe. Upon activating a stepper motor, its output shaft drives a feeding auger to rotate, conveying the material upwards. The material then enters the drying cylinder through a second feeding pipe and a feeding cylinder. Upon activating a drive motor, its output shaft drives multiple stirring blades to rotate simultaneously, continuously stirring the algae. Powering on the heating grid and turning on a fan blows hot air inwards, drying the continuously stirred algae. Finally, the algae is discharged by opening a valve on the discharge pipe. This blue-green algae harvesting, treatment, and recycling machine features a reasonable structural design and is easy to use. It can automatically harvest and collect blue-green algae from water bodies and perform drying operations. The entire process requires minimal manual intervention, effectively improving work efficiency and reducing the labor intensity of workers, fully meeting the needs of water purification.
[0005] However, it has certain drawbacks: the colloidal sheath structure surrounding the cyanobacteria cells is highly hydrophilic, so it is difficult to achieve effective water separation through the stirring action of the stirring plate. This results in the cyanobacteria cell clusters only being able to produce slight ruptures on the surface, and the bound water inside is difficult to release. As a result, the cyanobacteria with high water content directly enter the drying process, causing the hot air system to continuously consume a large amount of energy to evaporate the water. Utility Model Content
[0006] The purpose of this invention is to provide equipment for emergency treatment of cyanobacteria in drinking water sources of lakes and reservoirs, so as to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] An emergency treatment device for blue-green algae in lake and reservoir drinking water sources includes a hull. A suction mechanism is provided on the upper surface of the hull, and a support base is fixedly connected to the upper surface of the hull on the right side of the suction mechanism. A treatment tank is fixedly connected to the upper surface of the support base. A microfiltration membrane is fixedly connected through the lower surface of the treatment tank, and a drain pipe is fixedly connected to the lower surface of the treatment tank outside the microfiltration membrane. A fan connected to the inside of the treatment tank is fixedly connected to the upper surface of the treatment tank. A fan hood is fixedly connected to the upper end of the fan, and multiple heating pipes are fixedly connected inside the fan hood. An exhaust pipe connected to the inside of the treatment tank is fixedly connected to the upper surface of the treatment tank on the right side of the fan.
[0009] The processing tank has extrusion plates movably connected to both the left and right sides of its surface, and extrusion mechanisms are provided on both the front and rear sides of its surface. Each extrusion mechanism includes a gear, a rotating rod fixedly connected inside the gear, and racks meshing with both the upper and lower ends of the gear. A slide rail is embedded and slidably connected to the side of the rack closest to the processing tank, and an L-shaped plate is fixedly connected to the side of the rack furthest from the processing tank. The extrusion mechanism also includes a drive mechanism that moves the rack left and right.
[0010] As a further embodiment of this utility model: the suction mechanism includes a suction pump, the inlet end of the suction pump is fixedly connected to a suction pipe one, one end of the suction pipe one is fixedly connected to a suction cover, and the outlet end of the suction pump is fixedly connected to a suction pipe two.
[0011] As a further embodiment of this utility model: the driving mechanism includes a connecting block one, a telescopic cylinder is fixedly connected to the left side surface of the connecting block one, and a connecting block two is fixedly connected to the telescopic end of the telescopic cylinder.
[0012] As a further embodiment of this utility model: the drain pipe is located above the hull and movably passes through the support base; the rotating rod is rotatably connected to one side surface of the treatment tank; the slide rail is fixed to one side surface of the treatment tank; and the left and right L-shaped plates are respectively fixed to one side surface of the left and right extrusion plates.
[0013] As a further embodiment of this utility model: the suction pump is fixedly connected to the upper surface of the hull, and the suction pipe is fixedly connected to the upper surface of the treatment tank.
[0014] As a further embodiment of this utility model: the first connecting block is fixed to one side surface of the processing tank, and the second connecting block is fixed to the side surface of the upper rack away from the processing tank.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This invention significantly improves the dehydration efficiency of cyanobacteria through the synergistic effect of mechanical extrusion and hot air drying. The extrusion mechanism uses a bidirectional gear and rack transmission system to achieve synchronous reverse pressure. The two extrusion plates reciprocate in opposite directions under hydraulic drive, forming a dynamic extrusion-release cycle. This structure allows the cyanobacteria clusters to withstand alternating mechanical stresses within the tank, effectively breaking down the algal cell walls and releasing intracellular water. This can quickly remove most of the water from the cyanobacteria, significantly reducing the energy consumption of subsequent hot air drying. The hot air system continuously introduces temperature-controlled hot airflow to create a circulating drying environment within the tank, ensuring that residual water in the cyanobacteria evaporates completely and avoiding secondary pollution.

[0023] Please see Figures 1-4In this embodiment of the invention, the equipment for emergency treatment of blue-green algae in lake and reservoir drinking water sources includes a hull 1. A suction mechanism 2 is installed on the upper surface of the hull 1. The suction mechanism 2 includes a suction pump 3, which is fixedly connected to the upper surface of the hull 1.

[0024] Hull 1 can float on the surface of the lake or reservoir and support all the equipment on it;
[0025] The suction pump 3 is a centrifugal pump, which is a commonly used centrifugal conveying equipment in industry. It belongs to the category of industrial-grade centrifugal pumps (refer to GB / T 5657-2013 "Technical Conditions for Centrifugal Pumps"). The pump body adopts a double-end mechanical seal structure between the motor shaft and the pump chamber, and is equipped with a high-strength corrosion-resistant impeller assembly. Its sealing system can effectively prevent blue-green algae slime and water impurities from seeping into the bearing cavity. Combined with the flow channel design made of 316L stainless steel, the water containing blue-green algae will not be blocked, entangled or corroded during high-speed centrifugal conveying.
[0026] Half of the suction hood 5 is above the water surface, and the other half is below the water surface;
[0027] The suction pump 3 is used to pump drinking water containing blue-green algae from the lake into the treatment tank 8;
[0028] The microfiltration membrane 9 is used to block cyanobacteria inside the treatment tank 8 and discharge the water back into the lake through the drain pipe 10. The microfiltration membrane 9 can be a polymer microfiltration membrane with a pore size of less than 1 micrometer, preferably 0.45 micrometers or 0.2 micrometers, which can effectively trap cyanobacteria.
[0029] Blower 11 is used to blow air from the outside into the interior of treatment tank 8;

[0032] exist Figure 1 , Figure 3 and Figure 5 In the middle: Extrusion plates 15 are movably connected to both the left and right sides of the processing tank 8, and extrusion mechanisms 16 are provided on both the front and rear sides of the processing tank 8. The extrusion mechanism 16 includes a gear 17, and a rotating rod 18 is fixedly connected inside the gear 17. The rotating rod 18 is rotatably connected to one side surface of the processing tank 8, and racks 19 are meshed at both the upper and lower ends of the gear 17. A slide rail 20 is slidably connected to the side surface of the rack 19 near the processing tank 8. The slide rail 20 is fixedly connected to one side surface of the processing tank 8, and the rack 19 is away from the processing tank. An L-shaped plate 21 is fixed to one side surface of the 8, and the left and right L-shaped plates 21 are respectively fixed to one side surface of the left and right extrusion plates 15. The extrusion mechanism 16 also includes a drive mechanism 22 that drives the rack 19 to move left and right. The drive mechanism 22 includes a connecting block 1 23, which is fixed to one side surface of the processing tank 8. A telescopic cylinder 24 is fixed to the left side surface of the connecting block 1 23, and a connecting block 25 is fixed to the telescopic end of the telescopic cylinder 24. The connecting block 25 is fixed to the side surface of the upper rack 19 away from the processing tank 8.
[0033] The rotating rod 18 and the processing tank 8 can be rotatably connected by a bearing, with the outer ring of the bearing fixed to the processing tank 8 and the rotating rod 18 fixed to the inner ring of the bearing.
[0034] The telescopic cylinder 24 is preferably an electric cylinder. When it extends, it can drive the upper rack 19 to move to the right. Under the action of the gear 17, the lower rack 19 moves to the left, that is, the two racks 19 move relative to each other. When it retracts, it can drive the upper rack 19 to move to the left. Under the action of the gear 17, the lower rack 19 moves to the right, that is, the two racks 19 move in opposite directions.
[0035] After the two racks 19 move relative to each other and the two extrusion plates 15 are just in contact, after the two racks 19 move away from each other and the two extrusion plates 15 are just flush with the inner side surface of the processing tank 8 at one end.
[0036] Two extrusion plates 15 are used to extrude and filter the cyanobacteria, removing a large amount of water and improving drying efficiency. During the displacement process, the lower surface of the extrusion plate 15 is always in contact with the inner lower surface of the treatment tank 8, and the front and rear sides are always in contact with the inner front and rear sides of the treatment tank 8. (During the opening process of the two extrusion plates 15, the cyanobacteria that fall onto their surfaces will be scraped onto the inner lower surface of the treatment tank 8, which will not affect the extrusion of the cyanobacteria.)
[0037] The working principle of this utility model is as follows: The hull 1 floats on the surface of the lake or reservoir. The suction pump 3 draws in the water containing blue-green algae through the suction hood 5 and the suction pipe 4, and then transports it to the treatment tank 8 through the suction pipe 6. After the microfiltration membrane 9 intercepts the blue-green algae, the purified water is discharged back to the lake or reservoir through the drain pipe 10. The blower 11 blows the hot air generated by the heating pipe 13 into the treatment tank 8 through the wind hood 12 to dry the blue-green algae. The water vapor is discharged through the exhaust pipe 14. During the extrusion process, the telescopic cylinder 24 extends and retracts continuously, which drives the upper rack 19 to move through the connecting block 25. The gear 17 drives the lower rack 19 to move in the opposite direction, so that the two extrusion plates 15 fixed to the L-shaped plate 21 move to the end relative to each other and then separate. This process is repeated to extrude water from the blue-green algae.
