Description

Technical Field

[0001] This invention relates to the field of river and lake algae treatment technology, and in particular to a rapid extraction and removal system for river and lake algae treatment. Background Technology

[0002] Eutrophication leads to the growth of numerous algae in water bodies. The death of these algae significantly depletes the oxygen content of the water, causing oxygen depletion and death of aquatic life, resulting in wastewater. Treatment of river water containing large amounts of algae often involves aeration to increase oxygen levels, followed by the introduction of microorganisms for further processing. However, before treatment, the already grown algae must be harvested. Ordinary algae treatment relies on manual harvesting, which is not only slow but also requires considerable manpower to remove the large amount of algae that is harvested.

[0003] Patent CN110185014B discloses a device for rapid algae extraction and removal, comprising a main body. A fixed plate is symmetrically and fixedly mounted on the lower left side of the main body. A cutting device is mounted on the fixed plate, capable of cutting long strips of algae. A pumping device is symmetrically mounted inside the main body, capable of pumping the cut algae, along with small algae floating on the water surface and water, upwards. A crushing and dehydrating device is connected to the right side of the pumping device. This invention, by cutting and then collecting, effectively separates algae from roots, achieving rapid algae removal. The algae is crushed after extraction, allowing for the storage of more algae in a single cleaning operation, facilitating subsequent cleaning. Furthermore, the device is detachable, making algae removal even easier.

[0004] It has the following disadvantages:

[0005] 1. The algae are ultimately collected in the storage chamber, and the algae cannot be easily removed from the storage chamber.

[0006] 2. After the algae are dehydrated by centrifugation in the storage chamber, they are still in a fluffy state and have a large volume. They do not have the function of compression, which makes it difficult for the next step of algae transfer and processing. Summary of the Invention

[0007] To address the problems mentioned in the background section, this invention provides a system for the rapid extraction and removal of algae in rivers and lakes.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A rapid extraction and removal system for treating algae in rivers and lakes includes a collector and a filter cartridge. The collector is connected to the filter cartridge. Two first rotating shafts are rotatably mounted on the collector. A collecting claw is fixed to the outside of the first rotating shaft. A cutting mechanism is provided inside the collector near the bottom. A squeezing mechanism is provided inside the filter cartridge. A baffle is hinged to the bottom end of the filter cartridge.

[0010] Preferably, a drive box is fixed on the collector, the drive box drives two first rotating shafts to rotate synchronously in opposite directions, the collecting claws are equidistantly distributed on the first rotating shafts, and the collecting claws on the two first rotating shafts are staggered.

[0011] Preferably, the cutting mechanism includes a first transmission box and a second transmission box. There are two first transmission boxes, which are distributed on both sides of the second transmission box. Two first rotating shafts pass through the two first transmission boxes respectively, and multiple cutting blades are rotatably mounted on the top of both the first and second transmission boxes.

[0012] Preferably, the mounting shaft of the cutting blade extends into the interior of the first transmission box and a first gear is fixed to its outer side, and a second gear is fixed to the outside of the first shaft, with the first gear meshing with the second gear.

[0013] Preferably, a synchronization box is fixed to the bottom of the collector, the second transmission box has the same transmission structure as the first transmission box, and the second gears in the first and second transmission boxes are synchronously driven through the synchronization box.

[0014] Preferably, the collecting claw has an arc-shaped structure and is provided with hook teeth.

[0015] Preferably, a second rotating shaft is rotatably installed inside the filter cylinder, and a sleeve is rotatably installed outside the second rotating shaft. The second rotating shaft is driven to rotate by a rotary motor, and a pressing plate is fixed to the outside of the sleeve and the second rotating shaft.

[0016] Preferably, a first gear ring is fixed to the outside of the second rotating shaft, a second gear ring is fixed to the top of the sleeve, and a plurality of third rotating shafts are provided between the first gear ring and the second gear ring. A third gear is fixed to the top and bottom of each third rotating shaft, one of which meshes with the first gear ring and the other with the second gear ring.

[0017] Preferably, a vertical lifting rod is movably installed on the outside of the filter cylinder, a fourth gear is fixed on the rotating shaft of the baffle, and a rack is fixed at the bottom end of the vertical lifting rod, with the rack meshing with the fourth gear.

[0018] Preferably, a guide rail is fixed to the outside of the second rotating shaft. The guide rail has a horizontal part and an inclined part. A guide groove is opened on the guide rail. A horizontally arranged sliding rod is fixed to the top of the vertical lifting rod. The end of the sliding rod away from the vertical lifting rod extends movably into the guide groove.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The entire system is installed on a boat and lowered into the water via a lifting mechanism. As the boat moves, the algae are driven directly into the collector by the water flow. The algae can be cut by a cutting mechanism. The first rotating shaft drives the collecting claw to grab the algae towards the inside of the collector and flush it into the filter cylinder for collection. When the entire system is lifted out of the water, the algae in the filter cylinder can be filtered out. The squeezing mechanism can squeeze the algae to squeeze out the water, which facilitates the further processing of the algae. The system has a compact structure and can quickly extract and remove algae from rivers and lakes.

[0021] 2. Through the design of the extrusion mechanism, when the rotary motor drives the second rotating shaft to rotate, it can directly drive the first toothed ring to rotate, which in turn drives one of the extrusion plates to rotate. Then, through meshing, it drives the third gear at the top of the third rotating shaft to rotate, which in turn drives the third gear at the bottom of the third rotating shaft to rotate. Through the meshing of the third gear at the bottom of the third rotating shaft with the second toothed ring, the second toothed ring can be driven to rotate in the opposite direction, which in turn drives the sleeve to rotate in the opposite direction, thereby driving the other extrusion plate to rotate in the opposite direction, thus achieving the purpose of pressure filtration.

[0022] 3. Utilizing a linkage mechanism, when the second rotating shaft rotates, it drives the guide rail to move relative to the vertical lifting rod. The sliding rod remains inserted in the guide groove. As the two extrusion plates rotate in opposite directions and gradually compress the filter, the sliding rod first slides in the guide groove on the horizontal section. During this process, the height of the vertical lifting rod remains constant, and the baffle keeps the bottom of the filter cylinder sealed. When the two extrusion plates rotate relative to each other and approach the completion of filtration, the sliding rod moves to the inclined section. Sliding in the guide groove on the inclined section, it gradually drives the vertical lifting rod upwards, thus automatically opening the baffle after filtration is complete, achieving the purpose of automatically discharging algae. The device is more efficient and convenient to use. Attached Figure Description

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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] Example 1

[0037] Reference Figure 1-10A rapid extraction and removal system for treating algae in rivers and lakes includes a collector 1 and a filter cylinder 3. The collector 1 is connected to the filter cylinder 3. Two first rotating shafts 102 are rotatably mounted on the collector 1. A collection claw 103 is fixed on the outside of the first rotating shafts 102. A cutting mechanism 2 is provided inside the collector 1 near the bottom. A squeezing mechanism is provided inside the filter cylinder 3. A baffle 301 is hinged to the bottom end of the filter cylinder 3.

[0038] The entire system is installed on a boat and lowered into the water via a lifting mechanism. As the boat moves, the algae are driven directly into the collector 1 by the water flow. The algae can be cut by the cutting mechanism 2. The first rotating shaft 102 rotates to drive the collecting claw 103 to grab the algae towards the inside of the collector 1 and flush it into the filter cylinder 3 for collection. When the entire system is lifted out of the water, the algae in the filter cylinder 3 can be filtered out. The algae can be squeezed by the squeezing mechanism to squeeze out the water, which facilitates the further processing of the algae.

[0039] Among them, a drive box 101 is fixed on the collector 1. The drive box 101 drives two first rotating shafts 102 to rotate synchronously in opposite directions. The collecting claws 103 are equidistantly distributed on the first rotating shafts 102, and the collecting claws 103 on the two first rotating shafts 102 are staggered. The collecting claws 103 have an arc-shaped structure and are provided with hook teeth 104.

[0040] The drive box 101 is driven by a motor, which, together with the transmission mechanism, drives the two first rotating shafts 102 to rotate synchronously in opposite directions. This allows the collecting claws 103 to push the algae toward the filter cartridge 3, and with the water flow, the algae can be flushed into the filter cartridge 3.

[0041] Example 2

[0042] Reference Figure 1-10 The difference between this embodiment and embodiment 1 is that the cutting mechanism 2 includes a first transmission box 201 and a second transmission box 202. There are two first transmission boxes 201, and the two first transmission boxes 201 are distributed on both sides of the second transmission box 202. Two first rotating shafts 102 pass through the two first transmission boxes 201 respectively, and multiple cutting blades 203 are rotatably installed on the top of both the first transmission box 201 and the second transmission box 202.

[0043] When the first rotating shaft 102 rotates, it can transmit power to the first transmission box 201, thereby driving multiple cutting blades 203 to rotate rapidly, thus achieving the purpose of cutting algae.

[0044] The mounting shaft of the cutting blade 203 extends into the interior of the first transmission box 201 and a first gear 204 is fixed on its outer side. A second gear 205 is fixed on the outside of the first shaft 102, and the first gear 204 meshes with the second gear 205.

[0045] The first rotating shaft 102 can drive the second gear 205 to rotate. The diameter of the second gear 205 is much larger than the diameter of the first gear 204, thereby driving the first gear 204 to rotate faster, which in turn drives the cutting blade 203 to rotate quickly to cut the algae.

[0046] Among them, the bottom end of the collector 1 is fixed with a synchronization box 206, the second transmission box 202 has the same transmission structure as the first transmission box 201, and the second gear 205 in the first transmission box 201 and the second transmission box 202 are synchronously driven through the synchronization box 206.

[0047] The second transmission box 202 is equipped with a belt and pulley. The belt drives the second gear 205 in the first transmission box 201 and the second transmission box 202 to rotate together, thereby driving the cutting blade 203 at the top of the second transmission box 202 to rotate and cut the algae.

[0048] Example 3

[0049] Reference Figure 1-10 The difference between this embodiment and embodiment 1 is that a second rotating shaft 4 is rotatably installed inside the filter cylinder 3, and a sleeve 401 is rotatably installed outside the second rotating shaft 4. The second rotating shaft 4 is driven to rotate by a rotary motor 403, and a pressing plate 402 is fixed to the outside of the sleeve 401 and the second rotating shaft 4 respectively.

[0050] The two extrusion plates 402 are joined together and face the collector 1, so that the extrusion plates 402 will not block the algae entering the filter cylinder 3. The algae enter the filter cylinder 3 from the two extrusion plates 402 on opposite sides. When the second rotating shaft 4 and the sleeve 401 rotate in opposite directions, they can drive the two extrusion plates 402 to rotate in opposite directions, thereby squeezing the algae collected in the filter cylinder 3, achieving the purpose of compressing and filtering the algae, which facilitates the further processing of the algae.

[0051] Among them, a first gear ring 405 is fixed to the outside of the second rotating shaft 4, a second gear ring 404 is fixed to the top of the sleeve 401, a plurality of third rotating shafts 406 are provided between the first gear ring 405 and the second gear ring 404, and a third gear 407 is fixed to the top and bottom of the third rotating shaft 406. One of the third gears 407 meshes with the first gear ring 405, and the other third gear 407 meshes with the second gear ring 404.

[0052] When the second rotating shaft 4 is driven to rotate by the rotary motor 403, it can directly drive the first gear ring 405 to rotate, which in turn drives one of the extrusion plates 402 to rotate. Then, through meshing, it drives the third gear 407 at the top of the third rotating shaft 406 to rotate, which in turn drives the third gear 407 at the bottom of the third rotating shaft 406 to rotate. Through the meshing of the third gear 407 at the bottom of the third rotating shaft 406 with the second gear ring 404, the second gear ring 404 can be driven to rotate in the opposite direction, which in turn drives the sleeve 401 to rotate in the opposite direction, thereby driving the other extrusion plate 402 to rotate in the opposite direction, thus achieving the purpose of pressure filtration.

[0053] Example 4

[0054] The difference between this embodiment and embodiment 3 is that a vertical lifting rod 303 is movably installed on the outside of the filter cylinder 3, a fourth gear 302 is fixed on the rotating shaft of the baffle 301, and a rack 304 is fixed at the bottom end of the vertical lifting rod 303, with the rack 304 meshing with the fourth gear 302.

[0055] When the vertical lifting rod 303 moves downward, it can drive the rack 304 to move downward. Through the meshing of the rack 304 and the fourth gear 302, the baffle 301 can be rotated and opened, so that the squeezed algae inside the filter cylinder 3 can be easily discharged. When the vertical lifting rod 303 moves upward, it can drive the baffle 301 to rotate and block the bottom of the filter cylinder 3.

[0056] Among them, the second rotating shaft 4 is fixed with a guide rail 5. The guide rail 5 has a horizontal part 502 and an inclined part 503. A guide groove 501 is opened on the guide rail 5. The top of the vertical lifting rod 303 is fixed with a horizontally arranged sliding rod 305. The end of the sliding rod 305 away from the vertical lifting rod 303 extends movably into the guide groove 501.

[0057] Using a linkage mechanism, when the second rotating shaft 4 rotates, it can drive the guide rail 5 to move relative to the vertical lifting rod 303. The sliding rod 305 is always inserted in the guide groove 501. During the process of the two extrusion plates 402 rotating in opposite directions and gradually extruding, the sliding rod 305 first slides in the guide groove 501 on the horizontal part 502. During this process, the height of the vertical lifting rod 303 remains unchanged, and the baffle 301 keeps the bottom of the filter cylinder 3 sealed. When the two extrusion plates 402 rotate in opposite directions and approach the state of filter pressing completion, the sliding rod 305 moves to the inclined part 503. When it slides in the guide groove 501 on the inclined part 503, it can gradually drive the vertical lifting rod 303 to move upward, so that the baffle 301 will automatically open after the filter pressing is completed, so as to automatically discharge the algae. The device is more efficient and convenient to use.
