Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 2This utility model provides an embodiment of a waste salt separation device for fly ash washing, comprising a housing 1. A feed box 2 is fixedly connected to the top of the housing 1, allowing raw materials to be easily added into the device and ensuring uniform flow. A fixing plate 3 is fixedly connected to the top of the feed box 2, providing additional stability to the device structure and ensuring smooth operation. Multiple telescopic columns 4 are fixedly connected to both sides of the bottom of the fixing plate 3. The telescopic columns 4, through their expandability, provide a buffering effect for the device operation, reducing vibration and operating losses. Springs 5 ​​are sleeved on the outside of the telescopic columns 4, providing elastic restoring force under the action of the telescopic columns 4, ensuring that the baffle 7 can quickly return to its original position, improving the working efficiency of the device.

[0033] Multiple telescopic columns 4 are fixedly connected to a drive plate 6 at their bottom. The drive plate 6 connects the telescopic columns 4 to the baffle 7, allowing the equipment to flexibly adjust the position of the baffle 7 during impact, precisely controlling the flow of raw materials. One end of the spring 5 is fixedly connected to one side of the fixed plate 3. This fixing method ensures that the force on the spring 5 is more even, preventing fatigue or deformation. The other end of the spring 5 is fixedly connected to one side of the drive plate 6, ensuring that the tensile force of the spring 5 can be directly transmitted to the drive plate 6, improving operational stability. A baffle 7 is fixedly connected to the bottom of the drive plate 6. The baffle 7 controls the flow path of the raw materials, achieving quantitative delivery of raw materials through its opening and closing action. The outer surface of the baffle 7 is slidably connected to the inner wall of the feed box 2. This sliding connection design ensures the flexibility of the baffle 7's movement and reduces the impact of wear on the equipment.

[0034] A drive assembly is fixedly connected to the top of housing 1, providing the main power source for the entire device and ensuring continuous operation. A cleaning assembly is fixedly connected to the front end of the drive assembly, responsible for removing impurities during operation and ensuring the filter screen 16 remains unobstructed. The drive assembly includes motor 8, which serves as the core drive unit, providing stable power to the device through efficient operation. The bottom of motor 8 is fixedly connected to the top of housing 1, and this stable installation effectively reduces vibration and noise during operation. A drive wheel 9 is fixedly connected to the drive end of motor 8, which provides rotational power to driven wheel 10 and other components via belt 11. Driven wheel 10 is rotatably connected to the front end of feed box 2, and its rotation, in conjunction with drive wheel 9, ensures smooth power transmission.

[0035] A belt 11 externally couples the driving wheel 9 and the driven wheel 10. The belt 11 serves as the transmission medium, and its high-efficiency transmission performance minimizes power loss. Both the driving wheel 9 and the driven wheel 10 are fixedly connected to striking rollers 12. These rollers 12, through high-speed rotation, strike the drive plate 6, causing it to push the raw material into the equipment at a set quantity. The outer surface of the striking rollers 12 contacts the bottom of the drive plate 6. This direct contact allows the striking rollers 12 to quickly transmit power, ensuring the synchronous movement of the drive plate 6.

[0036] refer to Figure 2 and Figure 3 The cleaning assembly includes an extension plate 13, which pulls a connecting rod 14 when the driven wheel 10 rotates, providing a power source for the cleaning plate 15. The rear end of the extension plate 13 is fixedly connected to the front end of the driven wheel 10. This installation method maximizes the utilization of the driven wheel 10's rotational force, improving cleaning efficiency. The other end of the extension plate 13 is hinged to the connecting rod 14. The hinged design of the connecting rod 14 increases the range of motion of the cleaning assembly, adapting to different operating conditions. The end of the connecting rod 14 furthest from the extension plate 13 is hinged to the cleaning plate 15. During operation, the cleaning plate 15 contacts the surface of the filter screen 16, removing surface impurities and preventing clogging. A chute is provided at the front end of the feed box 2, providing guidance for the cleaning plate 15 and ensuring the accuracy of the cleaning movement. One side of the cleaning plate 15 is slidably connected to the inner wall of the chute. This sliding connection design improves the stability of the cleaning plate 15's movement and reduces operating friction. A filter screen 16 is fixedly connected to the inner wall of the feed box 2. The filter screen 16 is used for preliminary screening of large particulate impurities in the raw materials to ensure smooth operation of the equipment. The bottom of the cleaning plate 15 contacts the top of the filter screen 16. During its movement, the cleaning plate 15 pushes away the blockage impurities, thereby keeping the filter screen 16 unobstructed. A stirring assembly is fixedly connected to the inner wall of the box 1. The stirring assembly is responsible for fully mixing the raw materials and chemical agents to improve the separation effect.

[0037] refer to Figure 2 and Figure 4 The mixing assembly includes a second motor 17, which provides power for the mixing process through efficient operation, ensuring uniform mixing. The second motor 17 is externally fixed to the inner wall of the housing 1, and this stable installation improves the overall reliability of the equipment. A transmission rod is fixedly connected to the drive end of the second motor 17, which transmits the rotational power of the motor to the stirring rods 18 and the scraper 19, thus realizing the mixing action. Multiple stirring rods 18 are externally fixed to the transmission rod. The function of the stirring rods is to thoroughly agitate the raw materials and chemical agents, making the mixture more uniform.

[0038] A scraper 19 is fixedly connected to the external part of the drive rod. During the mixing process, the scraper assists in cleaning residues at the bottom of the tank 1, preventing blockages and material waste. A drain pipe 20 is fixedly connected to the right end of the tank 1. The drain pipe is used to discharge the separated water, ensuring thorough separation of liquid and solid. A slag discharge pipe 21 is fixedly connected to the bottom of the tank 1. The slag discharge pipe is used to discharge solid waste, and the scraper assists in slag discharge to prevent blockages. A packing tube 22 is fixedly connected to the top right end of the belt 11. The packing tube 22 is used to add the chemical reagents required for separation, ensuring the separation effect. A sealing cap is threadedly connected to the top of the packing tube 22. The sealing cap design effectively prevents reagent leakage and ensures operational safety.

[0039] Working principle: When the equipment needs to be used, raw materials are added from the feed box 2. The raw materials are filtered through the filter screen 16 before entering the feed box 2. At this time, the motor 8 is started, which drives the drive wheel 9 to rotate. The drive wheel 9 then drives the belt 11 to rotate, which in turn drives the driven wheel 10 to rotate. The rotation of the drive wheel 9 and the driven wheel 10 drives the impact roller 12 to rotate. The rotation of the impact roller 12 strikes the drive plate 6, causing the drive plate 6 to move the baffle 7. During the movement of the drive plate 6... The compression spring 5 causes the telescopic column 4 to retract, providing power for subsequent reset. At this time, the feed box 2 is open, and the raw material will flow. Then the feed box 2 closes, and under the action of another impact roller 12, the left baffle 7 will open, allowing the raw material to enter the interior of the box 1. This enables quantitative addition of materials and helps to better perform separation operations. When the driven wheel 10 rotates, it will also drive the connecting rod 14 to pull the cleaning plate 15, causing the cleaning plate 15 to move on top of the filter screen 16, pushing away large particles of impurities on the surface of the filter screen 16, thereby preventing the filter screen 16 from being blocked.

[0040] When the raw materials enter the interior of the chamber 1, chemical agents are added through the packing pipe 22. At this time, the motor 2 17 is started, which drives the transmission rod to rotate. The transmission rod drives the stirring rod 18 and the scraper 19 to mix the raw materials and agents. Finally, the mixture settles, allowing the liquid and solid to separate. After a certain period of time, the valve on the drain pipe 20 is opened, allowing clean water to drain out. Finally, the valve on the slag discharge pipe 21 is opened to discharge the solid. When the solid is discharged, the motor 2 17 is started to drive the scraper 19 to discharge the solid, which helps to discharge the material and avoids blockage.

[0041] 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.
