Description

Technical Field

[0001] The present application relates to the technical field of water body treatment, and specifically to a silt dissolution and water oxygenation device for lake ecological restoration. Background Art

[0002] The main components of silt include suspended matter, sediments, organic matter and other solid particles in the water. It usually exists in water bodies such as rivers, lakes, reservoirs, sewage treatment plants, etc. The thickening and increase of silt will cause the water capacity of ponds or lakes to become shallower and smaller, and the living space of fish will be reduced, which is not conducive to high yields in aquaculture. At the same time, silt contains a large amount of organic matter, which will undergo oxidative decomposition under the action of microorganisms, consuming a large amount of dissolved oxygen in the water and causing anoxic conditions. Under hypoxic conditions, nitrogen-containing and sulfur-containing organic matter in the silt will be decomposed by bacteria to produce toxic and harmful substances such as ammonia and hydrogen sulfide. The accumulation of these substances in the water will affect the water quality and deteriorate the water body. Silt digestion usually refers to the process of treating silt to reduce its volume, stabilize its properties and remove harmful substances, with the aim of repairing the lake ecology.

[0003] To repair water bodies, aerators are often used to oxygenate the water, and chemical materials are used to dissolve the sludge in the water. Acid digestion is one of the commonly used chemical methods. This method involves adding acids (such as nitric acid, sulfuric acid, and hydrochloric acid) to cause a chemical reaction between the organic and inorganic substances in the sludge, thereby decomposing them. However, when using chemical methods to dissolve sludge, the long-term accumulation of sludge in the water body causes the chemical agents to penetrate slowly, affecting the digestion efficiency.

[0004] Therefore, the present application provides a silt dissolution and water oxygenation equipment for lake ecological restoration to solve the above problems. Utility Model Content

[0005] The present application provides a silt dissolution and water oxygenation equipment for lake ecological restoration, aiming to solve the problems of the existing silt dissolution technology proposed in the background technology, in which the silt in the water body is accumulated tightly on the surface for a long time and the chemical agents penetrate slowly, affecting the dissolution efficiency when using chemical methods to dissolve the silt.

[0006] To achieve the above objectives, the present application provides the following technical solution: a silt dissolution and water oxygenation device for lake ecological restoration, comprising a wheeled aerator for oxygenating water, a support rod fixedly mounted on the wheeled aerator, and a float fixedly mounted on the support rod at one end away from the wheeled aerator for supporting the wheeled aerator to float on the water surface, wherein the wheeled aerator is provided with a silt dissolution mechanism:

[0007] The sludge disintegration mechanism includes a rotating shaft fixedly mounted on the output shaft of the wheeled aerator, a telescopic shaft is sleeved on the rotating shaft, a mounting plate is fixedly mounted on the end of the telescopic shaft away from the wheeled aerator, at least three stirring rods uniformly distributed in the circumferential direction are fixedly mounted on the side of the mounting plate away from the telescopic shaft, a pump body is fixedly mounted on the support rod, and a communicating infusion tube is fixedly mounted on the pump body. In this way, when the water body is oxygenated by the wheeled aerator, the telescopic shaft is pulled to adjust the length according to the water depth, and then the wheeled aerator is placed on the water surface. The float supports the wheeled aerator through the support rod, the rotating shaft and the telescopic shaft are inserted into the water body, and the stirring rod contacts the bottom silt. Then the configured chemical solution is poured into the pump body, and the wheeled aerator is started to drive the impeller to actively oxygenate the water body. At the same time, the rotating shaft is driven to rotate by the output shaft, and the rotating shaft drives the telescopic shaft to rotate. The telescopic shaft drives the stirring rod on the mounting plate to rotate. The stirring rod rolls up the silt in the water body, suspends the silt, and destroys the dense layer on the surface of the silt. Then the pump body is started, and the chemical solution is input into the bottom layer of the water body through the infusion tube to quickly contact the silt, thereby accelerating the efficiency of silt digestion.

[0008] Preferably, in order to accelerate stirring, a plurality of evenly spaced stirring heads are fixedly mounted on the stirring rod to reduce the resistance between the stirring rod and the sludge, so that the sludge can be stirred more conveniently.

[0009] Preferably, in order to replenish the chemical solution, a feed hopper arranged in a frustum shape is fixedly mounted on the pump body, and a one-way valve is fixedly mounted on the end of the infusion tube away from the pump body to accelerate drug delivery efficiency.

[0010] Preferably, in order to fix the stirring rod, a clamping plate is fixedly mounted on the mounting plate, the stirring rod is clamped in the clamping plate, and a bolt is screwed on the outer wall of the clamping plate, so as to facilitate disassembly and maintenance.

[0011] Preferably, in order to adjust the length of the telescopic shaft, a spring cavity is provided in the rotating shaft, a spring block is slidably installed in the spring cavity and sequentially passes through the rotating shaft and the outer wall of the telescopic shaft, and a spring is fixedly installed in the spring cavity. When the appropriate length is reached, the spring pushes the spring block out and engages with the telescopic shaft.

[0012] Preferably, in order to stabilize the one-way valve, a guide plate is fixedly mounted on the outer wall of the telescopic shaft at one end close to the mounting plate, and the end of the infusion tube with the one-way valve is plugged into the guide plate, thereby accelerating the contact rate between the chemical solution and the sludge.

[0013] This equipment adjusts the length according to the water depth by pulling the telescopic shaft, and then places the wheeled aerator on the water surface. The float supports the wheeled aerator through the support rod, the rotating shaft and the telescopic shaft are inserted into the water body, and the stirring rod contacts the bottom silt. Then the configured chemical solution is poured into the pump body, and the wheeled aerator is started, driving the impeller to actively oxygenate the water body. At the same time, the rotating shaft is driven to rotate by the output shaft, and the rotating shaft drives the telescopic shaft to rotate. The telescopic shaft drives the stirring rod on the mounting plate to rotate. The stirring rod rolls up the silt in the water body, suspending the silt and destroying the dense layer on the surface of the silt. Then the pump body is started, and the chemical solution is input into the bottom layer of the water body through the infusion tube to quickly contact the silt, thereby accelerating the efficiency of silt digestion.

[0014] The device inserts the one-way valve into the hole of the guide disk so that the one-way valve is aligned with a position close to the sludge for drug delivery, thereby accelerating the contact rate between the chemical solution and the sludge, stabilizing the one-way valve, and being safe and reliable.

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] Example 1

[0023] This embodiment provides a silt dissolution and water oxygenation device for lake ecological restoration, such as Figure 1-4 As shown, the device includes a wheeled aerator 1 for oxygenating water, a support rod 2 fixedly mounted on the wheeled aerator 1, and a float 3 fixedly mounted on the support rod 2 at one end away from the wheeled aerator 1 for supporting the wheeled aerator 1 to float on the surface of the water. The wheeled aerator 1 is provided with a sludge dissolving mechanism 4:

[0024] The sludge disintegration mechanism 4 includes a rotating shaft 41 fixedly mounted on the output shaft of the wheeled aerator 1, a telescopic shaft 42 is sleeved on the rotating shaft 41, a mounting plate 43 is fixedly mounted on the end of the telescopic shaft 42 away from the wheeled aerator 1, and at least three stirring rods 44 uniformly distributed in the circumferential direction are fixedly mounted on the side of the mounting plate 43 away from the telescopic shaft 42, a pump body 46 is fixedly mounted on the support rod 2, and a liquid infusion tube 47 is fixedly mounted on the pump body 46.

[0025] During use, the telescopic shaft 42 is pulled to adjust the length according to the water depth, and then the wheeled aerator 1 is placed on the water surface. The float 3 supports the wheeled aerator 1 through the support rod 2, the rotating shaft 41 and the telescopic shaft 42 are inserted into the water body, and the stirring rod 44 contacts the bottom silt. Then the configured chemical solution is poured into the pump body 46, and the wheeled aerator 1 is started to drive the impeller to actively oxygenate the water body. At the same time, the rotating shaft 41 is driven to rotate through the output shaft, and the rotating shaft 41 drives the telescopic shaft 42 to rotate. The telescopic shaft 42 drives the stirring rod 44 on the mounting plate 43 to rotate. The stirring rod 44 rolls up the silt in the water body, suspends the silt, and destroys the dense layer on the surface of the silt. Then the pump body 46 is started, and the chemical solution is input into the bottom layer of the water body through the infusion tube 47 to quickly contact the silt, thereby accelerating the efficiency of silt digestion.

[0026] Specifically, a plurality of evenly spaced stirring heads 45 are fixedly mounted on the stirring rod 44. When in use, the stirring heads 45 can be directly inserted into the silt, reducing the resistance between the stirring rod 44 and the silt, so that the silt can be stirred more conveniently and the stirring efficiency is accelerated.

[0027] More specifically, a frustum-shaped feed hopper 48 is fixedly mounted on the pump body 46, and a one-way valve 49 is fixedly mounted on the end of the infusion tube 47 away from the pump body 46. During use, receiving the chemical solution through the feed hopper 48 makes it more convenient to add materials, and the one-way valve 49 prevents the chemical solution from being backflowed by the lake water during delivery, thereby accelerating the efficiency of drug delivery.

[0028] Furthermore, a clamping plate 410 is fixedly mounted on the mounting plate 43, and the stirring rod 44 is clamped in the clamping plate 410. A bolt 411 is screwed on the outer wall of the clamping plate 410. When in use, the tail end of the stirring rod 44 is inserted into the clamping plate 410, and then the clamping plate 410 and the stirring rod 44 are fixed by the bolt 411, which is convenient for disassembly and maintenance.

[0029] Furthermore, a spring cavity 412 is defined within the rotating shaft 41. A spring block 413 is slidably mounted within the spring cavity 412, extending through the outer walls of the rotating shaft 41 and the telescopic shaft 42 in sequence. A spring 414 is fixedly mounted within the spring cavity 412. During use, the spring block 413 is pressed, compressing the spring 414 and causing the spring block 413 to retract into the spring cavity 412. The telescopic shaft 42 is then pulled, adjusting the combined length of the telescopic shaft 42 and the rotating shaft 41 until the desired length is reached, causing the spring 414 to push the spring block 413 out and engage with the telescopic shaft 42.

[0030] It should be noted that a plurality of holes for engaging with the bullet feeding blocks 413 are evenly formed on the surface of the telescopic shaft 42 .

[0031] A guide plate 415 is fixedly mounted on the outer wall of the telescopic shaft 42, near the mounting plate 43. The end of the infusion tube 47, which has a one-way valve 49, is plugged into the guide plate 415. During use, the one-way valve 49 is inserted into the hole in the guide plate 415, aligning it with the sludge to administer the drug. This accelerates the contact rate between the chemical solution and the sludge, stabilizes the one-way valve 49, and ensures safety and reliability.

[0032] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
