Description

Technical Field

[0001] The utility model relates to the technical field of defoaming spraying devices for leachate treatment, in particular to a defoaming spraying device for leachate treatment. Background Art

[0002] As we all know, landfill and incineration technology is an important issue in my country's environmental protection. Since landfills and incineration plants inevitably produce leachate that seriously pollutes the environment, new leachate treatment plants have been built in various places to address this problem. In nitrification tanks, aeration causes a lot of foam in the tank, which requires the use of defoaming agents and hydraulic spray devices to promptly defoam to prevent leachate foam from overflowing from the tank outlet and polluting the environment.

[0003] Most of the existing defoaming spray devices for leachate treatment nitrification tanks are fixed on the top of the nitrification tank and cannot be adjusted according to the height of the liquid level in the nitrification tank, making it inconvenient to carry out targeted work, resulting in low defoaming efficiency. Therefore, we propose a defoaming spray device for leachate treatment to solve the problems in the above background technology. Utility Model Content

[0024] Reference Figure 1-4 , a defoaming spray device for leachate treatment, comprising a nitrification tank 1, a diversion mechanism, a regulating mechanism and a spiral nozzle 6;

[0025] A diversion mechanism is provided on the nitrification tank 1, a regulating mechanism is provided in the nitrification tank 1 and is connected to the diversion mechanism, and a spiral nozzle 6 is provided on the regulating mechanism;

[0026] The adjusting mechanism includes a telescopic tube 4, a sleeve 5, a fixed plate 1 7, a fixed plate 2 8, a transmission rod 9 and a floating plate 10. Four telescopic tubes 4 are provided in the nitrification tank 1. The four telescopic tubes 4 are all slidably sleeved with sleeves 5. Two identical fixed plates 1 7 are fixedly connected between the four sleeves 5. The same fixed plate 2 8 is fixedly connected between the two fixed plates 1 7. The center of the fixed plate 2 8 is fixedly connected to the transmission rod 9. A floating plate 10 is fixedly installed at one end of the transmission rod 9. Through the coordinated design between the nitrification tank 1, the diversion mechanism, the adjusting mechanism and the spiral nozzle 6, not only can the foam in the nitrification tank 1 be cleaned, but the spiral nozzle 6 can also be appropriately adjusted according to actual conditions.

[0027] In this embodiment, the diversion mechanism includes a circular tube 1 2 and a circular tube 2 3. The circular tube 1 2 is fixedly installed on the nitrification tank 1. One side of the circular tube 1 2 is sealedly connected to two circular tubes 2 3. One end of the four telescopic tubes 4 is respectively sealedly connected to the two circular tubes 2 3. The water is transported to the circular tube 1 2 by the drive of the liquid pump and the action of the external pipe 12. At the same time, the water is diverted to the four telescopic tubes 4 by the action of the two circular tubes 2 3, thereby achieving the effect of water diversion.

[0028] In this embodiment, the spiral nozzle 6 is sealed and connected to one end of the sleeve 5. At the same time, the action of the spiral nozzle 6 greatly increases the spraying area, further improving the defoaming effect. For the specific structure and working principle of the spiral nozzle 6, please refer to the document with application number: 202020747398.6. This is the existing technology and will not be elaborated on in detail. The four telescopic tubes 4 are arranged at equal intervals on the two circular tubes 2 3 to facilitate the full cleaning of the foam in the nitrification tank 1.

[0029] In this embodiment, the circular tube 1 2 , the two circular tubes 2 3 , the four telescopic tubes 4 and the sleeve 5 are made of stainless steel to improve the pressure bearing capacity and impact resistance.

[0030] In this embodiment, one end of the four telescopic tubes 4 is sealed with a piston 11, and the four pistons 11 are respectively slidably connected to the four sleeves 5. The four pistons 11 are fixedly sleeved with a sealing ring 1 and are respectively slidably connected to the four sleeves 5. The four sleeves 5 are fixedly installed with a sealing ring 2, and the four sealing rings 2 are respectively slidably connected to the four telescopic tubes 4 to improve the sealing performance.

[0031] In this embodiment, a feed port 13 and a discharge port are provided on the nitrification tank 1 to facilitate the entry and discharge of raw materials.

[0032] In this embodiment, one end of the circular tube 2 is sealedly connected to the external tube 12, one end of the external tube 12 is provided with a liquid pump, and one end of the liquid pump is connected to a water source to achieve the purpose of transporting water to the circular tube 2.

[0033] Working principle: When in use, water is transported to the circular tube 1 2 through the drive of the liquid pump and the action of the external pipe 12, and at the same time, the water is diverted to the four telescopic pipes 4 through the action of the two circular pipes 2 3, thereby achieving the effect of water diversion;

[0034] Then, the telescopic tube 4 is used to atomize the water in the water delivery sleeve 5 and spray it out through the corresponding spiral nozzle 6. At the same time, the spiral nozzle is used to form the sprayed water into a multi-layer cone shape and act on the foam in the nitrification tank 1, thereby achieving a defoaming effect. At the same time, the spiral nozzle 6 greatly increases the spraying area, further improving the defoaming effect.

[0035] During this process, when the liquid level in the nitrification tank 1 increases, the liquid in the nitrification tank 1 applies a force to the floating plate 10 through the action of the floating plate 10, so that the floating plate 10 pushes the fixed plate 2 8 upward through the action of the transmission rod 9. At the same time, the fixed plate 2 8 drives the four sleeves 5 to slide on the four telescopic tubes 4 respectively through the action of the two fixed plates 1 7. At the same time, the four sleeves 5 drive the corresponding spiral nozzles 6 to move synchronously, so that the spiral nozzle 6 maintains an effective distance from the liquid level in the nitrification tank 1, thereby achieving the effect of properly adjusting the spiral nozzle 6 according to actual conditions, thereby improving convenience and defoaming efficiency.

[0036] The technical progress achieved by the present invention over the prior art is that, through the cooperation of various components, not only can the foam in the nitrification tank 1 be cleaned, but the spiral nozzle 6 can also be properly adjusted according to actual conditions, thereby improving convenience and defoaming efficiency, and the structure is simple and more practical.
