Description

Technical Field

[0001] This utility model relates to the technical field of water washing and salt separation equipment, specifically a waste ash fly water washing and salt separation equipment. Background Technology

[0002] Waste incineration is an important method for urban waste disposal, but it generates a large amount of fly ash. This fly ash contains heavy metals (such as lead, cadmium, and mercury) and soluble salts (such as sodium chloride, potassium chloride, and sulfates). If it is directly landfilled or dumped, the soluble salts will seep into the soil and water bodies with rainwater, causing environmental pollution. At the same time, the presence of salts will also affect the subsequent resource utilization of fly ash (for example, when used as raw materials for building materials, salts will cause the material strength to decrease and its corrosivity to increase). Therefore, it is necessary to pre-treat fly ash using water washing and salt separation technology to achieve salt removal and resource recovery.

[0003] Chinese patent CN222659618U discloses a water washing and salt separation device for treating waste fly ash. This invention has a filter plate at the bottom of the rotating shaft. When the second motor drives the threaded seat downward through the lead screw, the threaded seat drives the filter plate downward through the mounting bracket and the rotating shaft in sequence. The filter plate can press down the waste fly ash floating on the liquid surface, so that the waste fly ash is completely submerged below the water level. This allows for comprehensive immersion of the waste fly ash in the water level, enabling uniform treatment of the waste fly ash and improving the salt separation effect.

[0004] However, the waste fly ash treatment water washing and desalination device mentioned in the above scheme only uses a stirring plate for stirring, which has poor stirring effect. In addition, the device is equipped with filter plates. The waste fly ash liquid often carries a large amount of dust, particles and other impurities. These substances will continuously adhere to and accumulate on the surface and pores of the filter plates, causing the filter plates to gradually become blocked. As the blockage intensifies, the filtration effect becomes poor.

[0005] Therefore, it is necessary to invent a waste ash fly water washing and salt separation device. Utility Model Content

[0006] The purpose of this invention is to provide a waste ash fly rinsing and salt separation device to solve the problems mentioned in the background art.

[0026] Furthermore, the top of the box body 1 is provided with a feed inlet 11, and the side of the box body 1 is provided with a liquid outlet pipe 19.

[0027] Working principle: In use, the fly ash enters the housing 1 through the feed inlet 11 and falls onto the filter screen 34 above the horizontal plate 33. Then, cleaning water is injected into the housing 1, and the motor 13 is started, which drives the hollow cylinder 14 to rotate. When the hollow cylinder 14 rotates, it drives the stirring rod 29 and multiple stirring rods 28 to rotate, which facilitates the stirring of the fly ash and water mixture and accelerates the dissolution of salt. At the same time, the motor 21 drives the threaded rod 24 to rotate in both directions, which drives the stirring rod 29 and multiple stirring rods 28 to move up and down. At this time, the stirring rod 29 and multiple stirring rods 28 move up and down and rotate at the same time, which improves the stirring effect and enhances the salt dissolution efficiency. When the stirring rod 29 moves downward, the scraper 291 at the bottom will stick to the surface of the filter screen 34 and continuously scrape off the dust and debris on the surface of the filter screen 34 during the stirring and rotation process, so as to prevent the filter screen 34 from being blocked and ensure that the water washing process is fully carried out. The salt solution after washing passes through filter screen 34 and is discharged from tank 1 through outlet pipe 19 for subsequent salt recovery treatment. The ash solids remain on filter screen 34. To clean the filter screen 34, unscrew the screw 18 threaded into the top of the fixing block 17, pull the long rod 31 connected to the horizontal plate 33, and pull the horizontal plate 33 out of the rectangular groove 322 on the inner wall of the box 1. The fluororubber 32 will then detach from the rectangular groove 321, allowing for quick disassembly of the filter screen 34. This facilitates the cleaning of residual dust and completes equipment maintenance.
