Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a wastewater treatment device for a drying tower. Background Technology

[0002] A drying tower is a device used to dry substances or materials with high humidity. It is widely used in many industries, such as chemical, food processing, pharmaceutical, paper, and building materials. The drying tower wastewater treatment device is a highly efficient wastewater treatment device, especially suitable for the treatment of industrial wastewater such as high-salt wastewater and high-concentration organic wastewater. In the food, pharmaceutical, chemical, and printing and dyeing industries, this device has become one of the important wastewater treatment devices.

[0003] In existing technologies, when treating wastewater in drying towers, hot air is usually unevenly distributed in the drying chamber, which can reduce the drying effect on wastewater. In addition, the wastewater is usually sprayed using a single spray head, which can lead to low spraying efficiency and make it difficult to spray wastewater quickly, thus prolonging the wastewater treatment time.

The booster pump is fixedly installed on one side of the tower body.

[0010] As a further description of the above technical solution:

[0011] The waste collection box has a door hinged to one side, and a threaded hole is provided on the upper surface of the door. A bolt is threaded into the inside of the threaded hole.

[0012] As a further description of the above technical solution:

[0013] A scraping assembly is provided between the top drying shell and the bottom drying shell.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model is equipped with a water treatment component, which enables the wastewater treatment device of the drying tower to guide the hot air to form a spiral air duct when the internal hot air is introduced, thereby helping to generate a vortex effect, prolonging the residence time of the hot air in the drying tower, allowing the hot air to come into more full contact with the pollutants in the wastewater, thereby improving the hot air utilization efficiency and enhancing the drying effect.

[0031] As attached Figure 4 As shown, the water treatment assembly includes a spiral tube 11, which is connected to one side of the fixed shell 6. One end of the spiral tube 11 is connected to one side of the drying bottom shell 3. Limiting shells 12 are fixedly connected to both sides of the inner wall of the sludge receiving tank 2. An adsorption plate 13 is provided between the two limiting shells 12. The spiral tube 11 causes the air blown by the blower 9 to form a spiral air channel when it passes through the spiral tube 11. When it is blown into the drying bottom shell 3, the air channel is further formed under the action of the impact force. The limiting shell 12 is used to install the adsorption plate 13 and facilitates the disassembly of the adsorption plate 13.

[0032] As attached Figure 5 As shown, a bottom annular pipe 16 is fixedly connected inside the drying top shell 4. A middle annular pipe 17 is arranged above the bottom annular pipe 16, and a top annular pipe 18 is arranged above the middle annular pipe 17. Multiple connecting pipes 19 are connected through the bottom annular pipe 16, the middle annular pipe 17, and the top annular pipe 18. Multiple atomizing nozzles 20 are connected through the lower surfaces of the bottom annular pipe 16, the middle annular pipe 17, and the top annular pipe 18, respectively. A conveying pipe 14 is connected through the upper surface of the bottom annular pipe 16. A booster pump 15 is connected through the middle of the conveying pipe 14. The booster pump 15 is fixedly installed on one side of the tower body 1. A door 21 is hinged to one side of the wastewater receiving tank 2. A threaded hole 22 is opened on the upper surface of the door 21. The bottom annular pipe 16, the middle annular pipe 17, and the top annular pipe 18 facilitate the annular spraying of wastewater.

[0033] As attached Figure 2 As shown, the internal thread of the threaded hole 22 is connected to a bolt 23, which is used to fix the closed box door 21.

[0034] As attached Figure 4As shown, a scraping assembly is provided between the drying top shell 4 and the drying bottom shell 3. The scraping assembly includes a gear ring 24, which is rotatably connected between the drying top shell 4 and the drying bottom shell 3. A mounting block 25 is fixedly connected to one side of the drying bottom shell 3. A gear 26 is rotatably connected to the upper surface of the mounting block 25. The gear ring 24 and the gear 26 are meshed. A hydraulic cylinder 27 is fixedly installed on one side of the drying top shell 4. A fixing block 28 is fixedly connected to the output end of the hydraulic cylinder 27. The gear ring 24 facilitates the reciprocating rotation of multiple scraper rods 32, and the gear 26 is used to drive the gear ring 24 to rotate.

[0035] As attached Figure 3 As shown, a rack 29 is fixedly connected to one side of the fixing block 28, and the rack 29 and the gear 26 are meshed. A fixing rod 30 is fixedly connected to one side of the drying bottom shell 3, and a connecting sleeve 31 is slidably connected to the outside of the fixing rod 30. The connecting sleeve 31 is fixedly connected to the lower surface of the rack 29, and the connecting sleeve 31 improves the stability of the rack 29 movement.

[0036] As attached Figure 6 As shown, multiple scraper rods 32 are fixedly connected to the inner wall of the toothed ring 24, which facilitates scraping the inner wall of the drying bottom shell 3.

[0037] Working principle: When treating wastewater, the heating grid 10 is turned on for preheating, and then the conveying pipe 14 is connected to the wastewater tank. The booster pump 15 is turned on to start conveying the water flow. Then the blower 9 is turned on. When the air is blown into the spiral tube 11 through the heating grid 10, hot air is formed. Under the action of the spiral tube 11, when the hot air is blown into the drying bottom shell 3 from one end of the spiral tube 11, the impact force will promote the formation of the spiral air duct, thus forming a spiral hot air duct. At this time, the wastewater is conveyed to the bottom annular tube 16 through the conveying pipe 14. Then, under the connection of the connecting pipe 19, it is conveyed to the middle annular tube 17 and the top annular tube 18. Then, it is sprayed out by the atomizing nozzle 20 to form mist droplets. When the mist droplets come into contact with the hot air, they are quickly evaporated by the hot air. Then, the solid matter settles and falls onto the adsorption plate 13, thereby treating the wastewater.

[0038] When a large amount of adhering material accumulates on the inner wall of the drying shell and needs to be scraped off, the hydraulic cylinder 27 is activated. Its output end drives the fixed block 28 to move, which in turn drives the rack 29 to move. When the rack 29 moves, it drives the connecting sleeve 31 to move. At this time, the connecting sleeve 31 slides outside the fixed rod 30, and through the meshing of the rack 29 and the gear 26, it drives the gear 26 to rotate. Through the meshing of the gear 26 and the gear ring 24, it drives the gear ring 24 to reciprocate, so that the gear ring 24 drives multiple scraper rods 32 to reciprocate and scrape off the impurities adhering to the inner wall of the drying bottom shell 3.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
