Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fly ash chelation and curing technology, specifically a green and environmentally friendly fly ash chelation and curing device. Background Technology
[0002] Fly ash is an inevitable byproduct of waste incineration, accounting for approximately 3% to 5% of the incinerated waste. In the fly ash of waste incinerators, inorganic matter is the main component, followed by heavy metal elements with a high leaching rate. If it is directly landfilled without pretreatment, heavy metals will leach out and migrate, causing secondary pollution to the soil and groundwater. Fly ash needs to be mixed with chelating agents during treatment.
[0003] The existing curing device does not mix the chelating agent and fly ash evenly enough, which affects the effect of subsequent stirring and curing. At the same time, it is inconvenient to stop spraying in time, resulting in waste. In order to avoid the above technical problems, it is necessary to provide a green and environmentally friendly fly ash chelating and curing device to overcome the defects in the existing technology.

[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. This utility model is equipped with a uniform spraying mechanism. The top rod and sealing plate are pushed up by an electric hydraulic rod, which releases the seal on the vertical pipe, allowing the chelating agent inside the storage tank to enter the distribution box through the vertical pipe.

[0029] A medicine storage tank 401 is bolted to the top of the top cover 3. A vertical pipe 402 is snapped into the middle of the bottom of the medicine storage tank 401. A diversion box 403 is snapped into the bottom of the vertical pipe 402 at the bottom of the top cover 3. A horizontal pipe 404 is snapped into the outside of the diversion box 403 at equal intervals, and a nozzle 405 is snapped into the bottom of the horizontal pipe 404 at equal intervals. A cross retaining ring 406 is snapped into the inner wall of the vertical pipe 402. An electric hydraulic rod 407 is bolted to the middle of the bottom of the diversion box 403. A top rod 408 is movably connected to the top of the electric hydraulic rod 407. A sealing plate 409 is snapped into the top of the top rod 408 at the top of the cross retaining ring 406. To facilitate sealing of the vertical pipe 402, the medicine storage tank 401 is filled with a chelating agent. The electric hydraulic rod 407 is powered by an external power source. The top of the top rod 408 passes through the top of the cross retaining ring 406.
[0030] A mixing and disassembly mechanism 5 is provided at the bottom of the outer side of the mixing cylinder 1. The mixing and disassembly mechanism 5 includes a fixing block 501, a lifting rod 502, a connecting block 503, a bottom cover 504, a rotary motor 505, a stirring rod 506, and an inlet / outlet pipe 507.
[0031] A fixing block 501 is equidistantly clamped at the bottom of the outer side of the mixing cylinder 1. A lifting rod 502 is rotatably connected inside the fixing block 501. A connecting block 503 is rotatably connected to the bottom of the lifting rod 502. A bottom cover 504 is clamped at one end of the connecting block 503 corresponding to the bottom of the mixing cylinder 1. A rotary motor 505 is bolted to the bottom of the bottom cover 504. A stirring rod 506 is clamped at the output shaft of the rotary motor 505 corresponding to the inside of the mixing cylinder 1. Inlet and outlet pipes 507 are clamped at the top and bottom of one end of the outer side of the mixing cylinder 1. To ensure sealing, a sealing gasket is pasted at the connection between the bottom cover 504 and the mixing cylinder 1. The rotary motor 505 is powered by an external power source. Plugs are threadedly connected to the inner walls of the inlet and outlet pipes 507.
[0032] An inlet pipe 6 is snapped into the bottom of the outer side of the medicine storage tank 401, and a one-way valve 7 is snapped into the inside of the inlet pipe 6. Sleeves 8 are snapped into the top of the inside of the medicine storage tank 401 at equal intervals. A sliding rod 9 is movably connected inside the sleeve 8. A pressure plate 10 is snapped into the bottom of the sliding rod 9 at the position inside the medicine storage tank 401. Tension springs 11 are snapped into the outer side of the sleeve 8 between the pressure plate 10 and the medicine storage tank 401. In order to facilitate increasing the spraying pressure, there are five sleeves 8. The outer side of the pressure plate 10 is tightly fitted to the inner wall of the medicine storage tank 401.
[0033] The working principle and usage process of this utility model are as follows: First, fly ash is transported into the mixing drum 1 through an inlet / outlet pipe 507, causing the fly ash to accumulate inside the mixing drum 1. At the same time, the electric hydraulic rod 407 is activated to push the top rod 408 and the sealing plate 409 upward, causing the sealing plate 409 to separate from the cross retaining ring 406, releasing the seal on the vertical pipe 402. This allows the chelating agent inside the storage tank 401 to enter the distribution box 403 through the vertical pipe 402, and then enter the horizontal pipe 404. Water mist is sprayed out through the nozzle 405, facilitating the uniform mixing of the chelating agent and the fly ash. In addition, when the fly ash is stopped from being transported, the electric hydraulic rod 407 drives the top rod 408 and the sealing plate 409 to descend, causing the sealing plate 409 to adhere to the cross retaining ring 406, sealing the vertical pipe 402, preventing the chelating agent from flowing down, stopping the spraying of the agent, and preventing waste.
[0034] Next, the chelating agent is conveniently added to the inside of the medicine storage tank 401 through the liquid inlet pipe 6, and the backflow is prevented by the one-way valve 7. In addition, the tension spring 11 pushes the pressure plate 10 and the slide rod 9 to slide down along the inner wall of the sleeve 8 to squeeze the chelating agent inside the medicine storage tube 401, thereby increasing the pressure of subsequent spraying and ensuring the spraying effect.
[0035] Finally, the rotary motor 505 is started to drive the stirring rod 506 to rotate, stirring the fly ash sprayed with chelating agent inside the mixing drum 1 to ensure thorough mixing. The mixture is then discharged through another inlet / outlet pipe 507 for subsequent processing. In addition, the rotating lifting rod 502 pushes the connecting block 503, the bottom cover 504 and the rotary motor 505 down, making it easy to remove the stirring rod 506 out of the mixing drum 1 for easy disassembly and cleaning, and to prevent residue from remaining.
[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
