Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of solid waste treatment and synthetic soil, and particularly relates to a device and method for synthesizing artificial soil by using solid waste. BACKGROUND

[0002] A large amount of industrial waste slag is generated in industrial production activities, and these waste slags contain various heavy metals, harmful substances and substances that are difficult to naturally degrade. When these solid wastes need to be treated, landfill and incineration are generally used for treatment. However, while the solid waste is being treated, incineration and landfill can cause a series of environmental crises such as land occupation, groundwater pollution and air pollution.

[0003] In the field of agriculture, especially in ecological environment restoration engineering, the demand for soil resources is very urgent. Since high-quality soil is the basis for crop growth, however, due to long-term unreasonable development and utilization, soil erosion and pollution and other factors, natural high-quality soil resources are gradually decreasing, and problems such as land degradation, limited crop yield and ecological system imbalance are becoming increasingly prominent. However, some solid waste contains nutrients similar to natural soil, such as river silt, which is rich in organic matter, nitrogen, phosphorus, potassium and other nutrient elements and humus colloid. It not only can enhance soil fertility and promote plant growth, but also can improve soil structure and improve soil aeration and water retention capacity. Therefore, promoting the resource utilization of solid waste and safely and efficiently synthesizing artificial soil can not only reduce the harm to the environment during the treatment of solid waste, but also provide good soil resources. However, in the prior art, the synthesized artificial soil only solves the soil physical properties such as soil aggregate, and does not replenish the soil nutrients. Therefore, some improvers are generally added to the synthetic soil to improve the chemical fertility of the artificial soil and the biological activity of the soil.

[0004] However, during the mixing process, some materials need to be fermented. After fermentation, some lumps are generated in these materials. If these lumps cannot be broken up during mixing, the uniformity of subsequent mixing with other materials will be affected, which in turn leads to inconsistent soil composition. In addition, some components (such as improvers) are added in small amounts and are difficult to mix uniformly with other components, which also affects the uniformity of the soil composition, making it difficult for the synthesized artificial soil to achieve the desired effect. SUMMARY

[0067] (Three) beneficial effects

[0068] Compared with the prior art, the device and method for synthesizing artificial soil from solid waste have the following beneficial effects:

[0069] 1. In the application, as the stirring rod rotates, the connecting seat rotates around the axis of the stirring rod, so that the flexible connecting piece drives the crushing rod to rotate. In this process, the flexible connecting piece has elasticity, and in the process of rotating the stirring rod, the inertia of the crushing rod is increased, so that the crushing rod is thrown up under the action of centrifugal force in the process of rotating the stirring rod. Therefore, the crushing rod is arranged to scatter the clumps in the material, so that the material with uniform and loose texture can be conveniently output, and the uniformity of the subsequent mixing process and the quality of the final product are improved, and the problem of uneven mixing of multiple materials caused by clumps is avoided.

[0070] 2.

[0071] 3. In the application, the fan sends air to the air supply cylinder through the air exhaust pipeline, when the air entering the air supply cylinder is quickly discharged through the air supply groove, the high-speed flowing air first contacts the A side of the air supply groove, the flow direction of the air is changed through the setting of the A side, and the air is aligned with the conical hopper, so that the high-speed flowing air preliminarily mixes the material entering the conical hopper, then the material falls on the rotating umbrella-shaped material scattering disc, is thrown to the inner wall of the secondary mixing tank under the action of centrifugal force, and finally the falling material is finally mixed through the stirring frame, so that multiple different materials can be mixed, and the nutrient distribution of the finally synthesized artificial soil is uniform, and the physical properties are consistent.

[0072] 4、The application, by the setting of the broken material assembly, the agglomerates in the mixture are scattered, the subsequent uniform mixing is facilitated, the problem of uneven mixing caused by agglomeration is avoided, through the cooperation of the adding assembly and the material mixing and homogenizing assembly, not only the material can be conveyed according to the ratio of different materials at the beginning, so as to avoid the problem of uneven artificial soil composition caused by improper proportion of each material when adding, and different kinds and properties of materials can be uniformly mixed.

[0086] In the process of using solid waste to make artificial soil, first, the mixture is prepared, that is, the river silt (Baotou Kunlun Reservoir silt), fly ash, poultry manure, zeolite powder, fermentation agent (syrup, starch, fish protein, urea and whole milk powder are configured according to a certain proportion) are mixed uniformly, then covered with film and high temperature oxygen consumption fermentation (temperature and fermentation time are selected according to the specific situation), and the mixture is obtained.

[0087] Then the mixture is mixed with fly ash, desulfurization gypsum and a small amount of zeolite powder, ecological mineral nutrient modifier and ecological nutrient rejuvenator according to a certain proportion, then scattered by using a high-speed blade crusher, and then scattered by using a blowing machine to obtain artificial soil.

[0088] Among them, it needs to be supplemented that the ecological mineral nutrient modifier is prepared by mixing potassium-rich slate, potassium feldspar, dolomite, serpentine, limestone and potassium silicate according to a certain proportion, and then placed in a muffle furnace, heated from room temperature to 1000℃ at a rate of 1℃ / min, kept for 20min, then heated from 1000℃ to 1250℃ at the same rate, kept for 40min, and then rapidly air-cooled to room temperature.

[0089] The ecological nutrient rejuvenator is prepared by combining earthworm protein and Bacillus subtilis, Bacillus mucosus and Bacillus mucosus cultivated in Alashan Desert according to a certain proportion.

[0090] Specifically, since there are many hard lumps in the mixture after high temperature oxygen consumption fermentation, if these hard lumps cannot be effectively scattered in the subsequent secondary mixing, they will become defects in the product, which not only affects the penetration and development of root system, but also the materials wrapped inside cannot play a role.

The several storage tanks 22 are all installed on the secondary mixing tank 2 through the rotary valve 23.

[0101] Specifically, before mixing all materials, materials with smaller addition amounts (such as zeolite powder, ecological mineral nutrient modifier, and ecological nutrient rejuvenator) are first placed into their respective storage tanks 22. Then, a conveying device (usually a screw conveyor 3) is set up next to the secondary mixing tank 2, and the output end of the conveying device is connected to the feeding connector 21.

[0105] Specifically, when the materials falling on the conical hopper 25 are preliminarily mixed, the fan 33 is opened, the fan 33 transports air into the blower cylinder 30 through the setting of the exhaust pipeline 34, Figure 10 As shown in the above,

[0106] As shown in the above, Figure 9As shown, the air exhaust component includes an air supply pipeline 35, a mesh plate 36 and air exhaust grooves 37, the air supply pipeline 35 is communicated between the input end of the fan 33 and the sealing cylinder 24, the mesh plate 36 is installed at the bottom of the umbrella-shaped material distribution disc 27, the mesh plate 36 is located at the bottom of the mixing cylinder 26, the mesh plate 36 is arranged in a detachable manner, facilitating regular cleaning, and the mixing cylinder 26 is provided with a plurality of air exhaust grooves 37 at the top in a circumferential equiangular manner, and the air exhaust grooves 37 are located inside the sealing cylinder 24.

[0107] Specifically, the air entering the secondary mixing tank 2 passes through the gap between the outer wall of the mixing cylinder 26 and the discharge end of the conical hopper 25, reaches the bottom of the umbrella-shaped material distribution disc 27, then passes through the mesh plate 36 into the inside of the mixing cylinder 26, and the air entering the mixing cylinder 26 enters the inside of the sealing cylinder 24 through the air exhaust grooves 37, and then is discharged under the action of the fan 33 through the arrangement of the air supply pipeline 35.

[0108] The working principle or use process of the present application is as follows:

[0109] When the artificial soil is prepared by using solid waste, first, the mixture is prepared, that is, the river silt (Kundulun Reservoir silt in Baotou City), fly ash, poultry manure, zeolite powder, fermentation agent (syrup, starch, fish protein, urea and whole milk powder are configured according to a certain proportion) are mixed uniformly, and then covered with film and high-temperature oxygen consumption fermentation (the temperature and fermentation time are selected according to the specific conditions), and then the mixture is obtained.

[0110] Since there are many hard lumps in the mixture after high-temperature oxygen consumption fermentation, if these hard lumps cannot be effectively dispersed in the subsequent secondary mixing, they will become defects in the product, not only affecting the penetration and development of the root system, but also the materials wrapped inside cannot play a role, so it is necessary to disperse these hard lumps, and the mixture is sent into the primary mixing tank 1, then the first motor 17 is started, the first motor 17 drives one of the driving gears 14 to rotate, thereby driving the two driving gears 14 to rotate synchronously through the arrangement of the transmission shaft 18, at this time, the two driving gears 14 drive a plurality of intermediate gears 16 on the corresponding positioning disc 4 to rotate, thereby driving the inner tooth ring 15 on the corresponding rotating cylinder 5 to rotate, at this time, the driving direction of the driving gear 14 and the inner tooth ring 15 is opposite, thereby driving the rotating cylinder 5 and the transmission shaft 18 to rotate in the opposite direction.

[0111] With the rotation of the rotating cylinder 5, the plurality of positioning frames 7 and the spiral scraper 6 are driven to rotate around the axis of the rotating cylinder 5, and at the same time, the plurality of stirring rods 9 rotate around the axis of the rotating cylinder 5. With the rotation of the driving gear 14, the transmission shaft 18 is driven to rotate, thereby driving the plurality of first helical gears 19 to rotate. With the rotation of the rotating cylinder 5, the transmission shaft 18 rotates in the opposite direction, and the second helical gear 20 at the corresponding position is driven to rotate by the first helical gear 19, thereby driving the stirring rod 9 at the corresponding position to rotate, and the arc-shaped stirring rod 10 and the connecting seat 11 on the stirring rod 9 are driven to rotate, thereby stirring the mixture.

[0112] With the rotation of the stirring rod 9, the connecting seat 11 rotates around the axis of the stirring rod 9, thereby driving the crushing rod 13 to rotate through the flexible connecting piece 12. In this process, the flexible connecting piece 12 has elasticity, and during the rotation of the stirring rod 9, the inertia of the crushing rod 13 is increased, thereby under the action of centrifugal force, the crushing rod 13 is thrown up during the rotation of the stirring rod 9, thereby through the arrangement of the crushing rod 13, the clumps mixed in the material are broken up. At this time, the flexible connecting piece 12 is deformed to some extent, thereby relieving the impact on the stirring rod 9, and a plurality of tapered protrusions are arranged on each crushing rod 13, thereby further improving the efficiency of breaking up the clumps mixed in the material, facilitating the output of the material with uniform and loose texture, thereby improving the uniformity of the subsequent mixing process and the quality of the final product. Until the mixture enters the secondary mixing tank 2 under the action of the spiral scraper 6.

[0113] Before all the materials are mixed, a small amount of materials (such as zeolite powder, ecological mineral nutrient modifier, and ecological nutrient rejuvenator) are respectively put into the corresponding storage tank 22. Then, a conveying device (generally a screw conveyor 3) is arranged beside the secondary mixing tank 2, the output end of the conveying device is communicated with the feeding connector 21, and then a large amount of materials (such as fly ash and desulfurization gypsum) are mixed uniformly and put into the conveying device. When these materials and the mixture in the primary mixing tank 1 are simultaneously fed into the secondary mixing tank 2, the rotary valve 23 is opened, and the materials in the corresponding storage tank 22 are simultaneously fed into the secondary mixing tank 2. In the process of conveying the mixture and other materials, the speed of conveying the mixture, the speed of conveying other materials with large amount by the conveying device, and the discharging speed of the rotary valve 23 are controlled, thereby controlling the amount of the mixture and other materials with different proportions added into the secondary mixing tank 2 at the same time, thereby ensuring that the composition of the synthetic soil is more uniform.

[0114] When the mixture and the various materials enter the inside of the secondary mixing tank 2, the materials will fall on the conical hopper 25, at this time, the fan 33 is opened, and the fan 33 is arranged through the exhaust pipeline 34 to send air into the air supply cylinder 30, as shown in Figure 10 The air supply groove 32 is arranged on the B side of the ventilation groove 31, and the A side of the ventilation groove 31 opposite to the B side is arranged as an inclined surface. When the air entering the air supply cylinder 30 is quickly discharged through the air supply groove 32, the high-speed flowing air will first contact the A side of the air supply groove 32, and the flow direction of the air is changed through the arrangement of the A side, so as to be aligned with the conical hopper 25, so that the materials entering the conical hopper 25 are preliminarily mixed by the high-speed flowing air. The air entering the secondary mixing tank 2 will pass through the gap between the outer wall of the mixing cylinder 26 and the discharge end of the conical hopper 25 to the bottom of the umbrella-shaped material scattering disc 27, and then pass through the mesh plate 36 to enter the inside of the mixing cylinder 26. The air entering the mixing cylinder 26 will enter the sealed cylinder 24 through the exhaust groove 37, and then be discharged under the action of the fan 33 through the arrangement of the air supply pipeline 35.

[0115] When the materials entering the secondary mixing tank 2 are blown and preliminarily mixed together, then the materials will fall on the umbrella-shaped material scattering disc 27 through the gap between the outer wall of the mixing cylinder 26 and the discharge end of the conical hopper 25, at this time, the second motor 28 is opened, and the second motor 28 drives the mixing cylinder 26 to rotate, so as to drive the umbrella-shaped material scattering disc 27 to rotate through the arrangement of the mixing cylinder 26, so that the preliminarily mixed materials falling on the umbrella-shaped material scattering disc 27 rotate around the axis of the umbrella-shaped material scattering disc 27. At this time, the materials will be thrown to the inner wall of the secondary mixing tank 2 under the action of centrifugal force, and then fall to the bottom of the secondary mixing tank 2, and then be further mixed uniformly through the arrangement of the stirring frame 29, and then be sent to the next link through the arrangement of the conveyor 3, and then be further broken by the high-speed blade crusher, and then be blown by the blowing machine to obtain the artificial soil.

[0116] In the second embodiment, the device for mixing solid waste to obtain artificial soil is also provided with a method for mixing solid waste to obtain artificial soil, which comprises the following steps:

[0117] Firstly, a mixture is prepared. The river channel silt (the silt of the KunDunLun reservoir in Baotou city), fly ash, poultry manure, zeolite powder, and fermentation agent (prepared by mixing molasses, starch, fish protein, urea, and whole milk powder according to a certain proportion) are uniformly mixed, and then covered and high-temperature oxygen consumption fermentation (the temperature and fermentation time are selected according to the specific conditions) is carried out to obtain the mixture.

[0118] The second step involves conveying the mixture into the primary mixing tank 1. Then, the first motor 17 is turned on, driving one of the drive gears 14 to rotate. This, in turn, drives two other drive gears 14 to rotate synchronously via the transmission shaft 18. These two drive gears 14 then drive several intermediate gears 16 on the corresponding positioning discs 4 to rotate, which in turn drive the internal gear rings 15 on the corresponding rotating cylinders 5 to rotate. Since the drive gears 14 and the internal gear rings 15 rotate in opposite directions, the rotating cylinders 5 and the transmission shaft 18 rotate in the opposite direction. As the rotating cylinders 5 rotate, multiple positioning frames 7 and spiral scrapers 6 rotate synchronously around the axis of the rotating cylinders 5. The spiral scrapers 6 then push the mixture to move.

[0119] The third step is to stir the mixture. As the drive gear 14 rotates, it drives the transmission shaft 18 to rotate, which in turn drives several first helical gears 19 to rotate. As the rotating cylinder 5 rotates, since the transmission shaft 18 and the rotating cylinder 5 rotate in opposite directions, the first helical gears 19 drive the corresponding second helical gears 20 to rotate, which in turn drives the stirring rod 9 to rotate. This causes the arc-shaped stirring rod 10 on the stirring rod 9 and the connecting seat 11 to rotate, thus stirring the mixture.

[0120] The fourth step is to break up clumps. As the stirring rod 9 rotates, the connecting seat 11 rotates around the axis of the stirring rod 9, thereby driving the crushing rod 13 to rotate through the flexible connector 12. During this process, due to the elasticity of the flexible connector 12, the rotational inertia of the crushing rod 13 is increased during the rotation of the stirring rod 9. As the stirring rod 9 rotates, the crushing rod 13 is thrown up under the action of centrifugal force. Thus, the crushing rod 13 breaks up the clumps mixed in the material. At this time, the flexible connector 12 undergoes a certain deformation, thereby mitigating the impact of the impact on the stirring rod 9. In addition, each crushing rod 13 is provided with several conical protrusions, which further improves the efficiency of breaking up the clumps mixed in the material, making it easier to output a uniform and loose material, thereby improving the uniformity of subsequent mixing processes and the quality of the final product.

[0121] The fifth step is to add the materials. First, add the materials with small amounts (such as zeolite powder, ecological mineral nutrient modifier, and ecological nutrient rejuvenator) to the corresponding storage tanks 22, then set a conveying device (usually a screw conveyor 3) beside the secondary mixing tank 2, connect the output end of the conveying device to the feeding joint 21, then mix the materials with large amounts (such as fly ash and desulfurization gypsum) uniformly and put them into the conveying device, so that these materials and the mixture in the primary mixing tank 1 enter the secondary mixing tank 2 at the same time, then open the rotary valve 23 to put the materials in the corresponding storage tanks 22 into the secondary mixing tank 2 at the same time.

[0122] The sixth step is to control the feeding speed. During the conveying of the mixture and other materials, control the conveying speed of the mixture, the conveying speed of the conveying device for other materials with large amounts, and the discharging speed of the rotary valve 23, so as to control the amount of the mixture and other materials with different proportions added to the secondary mixing tank 2 at the same time, thereby ensuring that the composition of the synthetic soil is more uniform.

[0123] The seventh step is to mix the materials. When the mixture and various materials enter the secondary mixing tank 2, they will fall into the conical hopper 25. At this time, the fan 33 is started, and the fan 33 sends air to the air supply cylinder 30 through the exhaust pipe 34. As shown in Figure 10 The air supply groove 32 is provided on the B side of the ventilation groove 31, and the A side of the ventilation groove 31 opposite to the B side is provided with a slope. When the air entering the air supply cylinder 30 is quickly discharged through the air supply groove 32, the high-speed flowing air will first contact the A side of the air supply groove 32, change the flow direction of the air through the setting of the A side, and align with the conical hopper 25, so that the high-speed flowing air preliminarily mixes the materials entering the conical hopper 25. The air entering the secondary mixing tank 2 will pass through the gap between the outer wall of the mixing cylinder 26 and the discharge end of the conical hopper 25, come to the bottom of the umbrella-shaped material distribution disc 27, then pass through the mesh plate 36 into the mixing cylinder 26, and then the air entering the mixing cylinder 26 will pass through the exhaust groove 37 into the sealed cylinder 24, and then the air will be discharged under the action of the fan 33 through the air supply pipe 35.

[0124] The eighth step, the material is blown and mixed together in the secondary mixing tank 2, then the material will fall into the umbrella-shaped material disc 27 through the gap between the outer wall of the mixing cylinder 26 and the discharge end of the conical hopper 25, at this time the second motor 28 is started, the second motor 28 drives the mixing cylinder 26 to rotate, so that the umbrella-shaped material disc 27 is driven to rotate through the arrangement of the mixing cylinder 26, so that the material falling on the umbrella-shaped material disc 27 is rotated around the axis of the umbrella-shaped material disc 27, at this time the material is thrown to the inner wall of the secondary mixing tank 2 under the action of centrifugal force, then the material falls to the bottom of the secondary mixing tank 2, and is further mixed uniformly through the arrangement of the stirring frame 29.

[0125] The ninth step, output, through the arrangement of the conveyor 3, the material is sent to the next link, and then is further scattered by using a high-speed blade crusher and a blowing machine to obtain artificial soil.

[0126] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
