Description

[0002] With the explosive growth of municipal solid waste, incineration power generation technology as an effective treatment method has been widely used in some large cities in China. However, the fly ash generated during the incineration process is rich in high-concentration heavy metals and dioxin organic pollutants, which are considered as hazardous waste. In order to reduce the secondary pollution of the environment caused by these fly ash, proper treatment must be carried out, and the fly ash solidification device emerges as the times require.

[0003] The applicant has found that in the mixing process of fly ash and cement powder, the prior art mostly directly adds all fly ash and cement powder into the mixture. This method may have some drawbacks. When a large amount of fly ash and cement powder is added into the mixing device at one time, due to the large amount of material and limited stirring time, it may lead to uneven mixing. The distribution of fly ash and cement powder in the mixture may be uneven, affecting the solidification effect. In addition, a large amount of material mixed at one time requires a large stirring force and stirring time, which increases the energy consumption of the equipment. At the same time, uneven mixing may require additional stirring or processing steps, further increasing energy consumption. Due to uneven mixing, the quality of the solidified product may be unstable, and the ratio of fly ash and cement powder, mixing uniformity and other factors directly affect the strength and stability of the solidified body.

[0040] Through the negative pressure material extraction assembly 2, the material flushing pipe 15, the premixing barrel 16 and other related structure designs, in the working process of the present application, a small amount of cement powder and fly ash which can be mixed uniformly are introduced into the mixing device 19 for mixing, and a certain amount of cement powder and fly ash are introduced into the two feeding boxes 14, then when the motor 13 is started, it drives the square block 22 to reciprocate in the frame opening of the long frame plate 23 through the driving arm rod 21, and the reciprocating movement further drives the square rod 24 and the piston to slide in the air cylinder 25, so that the negative pressure is generated, when the square rod 24 moves in one direction, for example, the air extraction direction, the negative pressure can be generated in the temporary storage box 17 through the air extraction pipe 26, at this time, the electromagnetic valve at the upper end of the inclined pipe 18 is closed, the sealing assembly 5 is in the closed state, and the air extraction pipe 26 can be designed to have a filtering structure to avoid adsorbing dust, then the lower end of the opposite side of the two feeding boxes 14 is provided with the inclined material flushing pipe 15, and the cement powder and fly ash can be transported out through the negative pressure, the middle part of the material flushing pipe 15 is horizontally designed, and the other end thereof is downward and penetrates through the top of the premixing barrel 16, the outlet ends of the two material flushing pipes 15 are close to each other, so that the cement powder and fly ash powder falling from the feeding boxes 14 can be preliminarily mixed in the material flushing pipes 15, and are concentrated in the temporary storage box 17, and when the air is exhausted, the air is exhausted through the air outlet pipe 27 in one direction, so that the quantitative and flushing mixing can be continuously and uninterruptedly carried out, and after being concentrated to a certain amount, the electromagnetic valve of the inclined pipe 18 is opened to discharge the materials into the mixing device 19 for mixing and stirring.

[0041] The filter frame plate 28 is installed on the inner wall of the temporary storage box 17 and surrounds the air extraction pipe 26. One side of the filter frame plate 28 is inclined and provided with a filter screen, and the two feeding boxes 14 are provided with an inclined plate 112 on the two sides of the inner wall, and the inclined surface of the lower inclined plate 112 is below the inlet of the material flushing pipe 15.

[0042] In the premixing optimization design, the inclined screen of the filter frame plate 28 can avoid the dust being sucked into the air extraction pipe 26, and the inclined design facilitates the dust to slide along the inclined surface when the air is not extracted, and the inclined plate 112 design makes the dust at the material flushing pipe 15 not be pressed too much, so that the dust can be conveniently discharged for flushing mixing, and the efficiency is improved, and details are shown in Figure 7 .

[0043] The liquid spraying assembly 3 comprises an air compressor 31 mounted on one side of the gantry 1, and the air outlet pipe 27 is connected to the air inlet end of the air compressor 31. The compressed air pipe 33 of the air compressor 31 is provided with a timing electric valve 34, and the other end of the compressed air pipe 33 is designed as a contraction port 35 which is connected to an atomizing nozzle 37 through a straight pipe. The atomizing nozzle 37 is located inside the mixing device 19, and the bottom of the straight pipe is provided with a vertical thin pipe 36 which is inserted into the lower end of the liquid tank 32 containing the chelating agent and protrudes from the top. The atomizing nozzle 37 is located on the side of the outlet of the inclined pipe 18, and the timing electric valve 34 is synchronously opened and closed with the electromagnetic valve at the upper end of the inclined pipe 18.

[0044] By designing the liquid spraying assembly 3, the air compressor 31 can receive the gas sprayed from the air outlet pipe 27, compress and collect it, and then intermittently send high-pressure gas into the compressed air pipe 33 through the control of the timing electric valve 34. This design ensures that the gas can be output at a certain pressure and frequency, providing a stable gas source for subsequent liquid atomization. When the high-pressure gas flows through the contraction port 35, the flow rate of the gas increases due to the sudden reduction in diameter, and the pressure further increases, creating ideal conditions for the subsequent atomization process. At the same time, the thin pipe 36, as a key component connecting the liquid tank 32 and the atomizing nozzle 37, is vertically inserted into the bottom of the liquid tank, which helps to ensure that the chelating agent can be uniformly and continuously sucked. With the action of high-pressure gas, the chelating agent in the liquid tank 32 is sucked into the thin pipe 36 and meets the high-speed gas flow at the atomizing nozzle 37. Under the action of strong gas flow shear force, the chelating agent is dispersed into tiny droplets, forming a fine mist spray, which catalyzes the reaction, allowing the cement powder and ash powder to fully react and solidify. In this way, the negative pressure material extraction assembly 2 and the liquid spraying assembly 3 work together without the need for additional air suction pumps, and the timing electric valve 34 and the electromagnetic valve at the upper end of the inclined pipe 18 are synchronously opened and closed, allowing spraying while feeding, thereby achieving sufficient mixing and automatic continuous spraying, which is more efficient.

[0045] The stirring assembly 4 comprises two stirring shafts 41 rotatably connected to the inside bottom end of the mixing device 19, and stirring plates 42 are mounted on both sides of the stirring shafts 41. The stirring plates 42 are distributed alternately. Two gears 43 are rotatably mounted on the top of the mixing device 19, and the two gears 43 share a rotating shaft with the two stirring shafts 41. The two gears 43 are meshed with toothed plates 44 on one side. The toothed plates 44 are fixed to the bottom of the long frame plate 23 through connecting pieces. The toothed plates 44 are provided with sliding blocks on the outside, and the sliding blocks slide in the sliding grooves on the inside of the gantry 1.

[0046] By designing the stirring assembly 4, when the negative pressure material extraction assembly 2 is in operation, the long frame plate 23 moves back and forth in a straight line, which also makes the toothed plate 44 move back and forth, and each time the toothed plate 44 moves back and forth, the gear 43 rotates one circle, and then the stirring plate 42 of the two stirring shafts 41 rotates back and forth, this movement not only makes the stirring more uniform, but also effectively prevents the material from forming a dead angle in the mixing device 19, ensuring that the material can be fully mixed, secondly, the energy saving effect of the stirring assembly 4 is also very significant. Since it completely relies on the power generated when the negative pressure material extraction assembly 2 is working to drive, it does not need an additional motor or other power equipment, thereby greatly reducing the energy consumption.

[0047] The closing assembly 5 includes a U-shaped frame 51 fixed at the top of the premixing barrel 16, and the bottom of the U-shaped frame 51 is connected with two slide rods 52, the slide rods 52 pass through the rod holes of the closing plate 53, and the top of the closing plate 53 is connected with the U-shaped frame 51 through a spring 54, and the spring 54 exerts a pulling force on the closing plate 53 in a normal state, so that the closing plate 53 cannot close the round opening.

[0048] By designing the closing assembly 5, when suction is performed, the closing plate 53 overcomes the elastic force of the spring 54 through pressure, and slides down through the slide rods 52 to close the round opening with the top surface of the premixing barrel 16, so that external gas cannot enter, and the suction force received by the material flushing pipe 15 is stronger, which facilitates the suction of dust, and when the gas outlet pipe 27 discharges gas, the closing plate 53 moves upward, which facilitates the entry of gas, and avoids the uneven pressure of the premixing barrel 16.

[0049] Based on the above ideal embodiments of the present application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the contents in the specification, and must be determined according to the scope of claims.
