Description

Technical Field

[0001] The invention belongs to the technical field of solid waste modification, and specifically relates to a device for preparing a soil conditioner by utilizing multi-component solid waste. Background Art

[0002] Bulk solid wastes such as fly ash, gasification slag, desulfurized gypsum, and slag contain a large amount of relatively stable components such as silicon dioxide and aluminum oxide, which limits their scope of application and application effect. In practice, it is often necessary to perform surface modification or structural modification on bulk solid wastes to enhance their activity and achieve high value-added comprehensive utilization. The method of surface modification and re-functionalization of bulk solid waste particles is one of the main means to improve their high value-added utilization. Surface modification of bulk solid waste particles and loading of some functional additives can obtain a new type of functional material. This method can greatly improve the added value of bulk solid waste utilization, greatly mobilize the enthusiasm of enterprises for the deep utilization of bulk solid waste, and promote the deep resource utilization of bulk solid waste resources.

[0003] Solid waste material modification methods are mainly divided into physical modification and chemical modification. Physical modification includes grinding solid waste materials by mechanical grinding and other methods to reduce their particle size and increase their activity, and using hot air method to put solid waste materials into high-temperature hot air for treatment to make them have better physical properties and activity; chemical modification is to use chemical, biological and other agents to react with solid waste materials to change the physical structure and mechanical chemical properties of solid waste materials, thereby improving the performance of solid waste materials; in addition to using acidification to modify solid waste granular materials, the existing technology can also perform dry modification, such as the fly ash modification technology review published in the first issue of "China Non-metallic Mineral Industry Guide" in 2009: weigh a certain amount of fly ash, place it on a glass surface dish, and then take a certain amount of prepared modifier (with initiator) and spray it on the surface of the fly ash. After sufficient stirring, dry it in an oven at 100 degrees for 2 hours. h, a surface modified product of fly ash powder can be obtained, that is, the process of pouring fly ash into a high-speed mixer, adding a modifier at a certain temperature and speed, so that the modifier is coated on the outer surface of the fly ash.

[0042] Embodiment 1

[0043] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Fig.12 As shown, a device for preparing soil conditioner using multi-component solid wastes comprises a solid waste crushing tube 1, a conveying tube 2 and a solid waste modification tube 5, a supporting bottom plate 6 is arranged below the solid waste crushing tube 1 and the solid waste modification tube 5, the solid waste modification tube 5 is respectively arranged on both sides of the solid waste crushing tube 1, a crushing and grinding assembly is arranged in the solid waste crushing tube 1, the conveying tube 2 is connected to the lower end of the solid waste crushing tube 1, a three-way material distribution tube 3 is connected to the conveying end of the conveying tube 2, a screening frame 4 is connected above the solid waste modification tube 5, a discharge pipe port of the three-way material distribution tube 3 is located just above the screening frame 4, a stirring and modifying assembly is arranged in the solid waste modification tube 5, and the multi-component solid waste raw materials can be conveyed into the solid waste crushing tube 1, and the multi-component solid waste is crushed and ground by the crushing and grinding assembly to process the multi-component solid waste into small particles, and then The treated solid waste is transported to the solid waste modification cylinder 5, and a modifier is added to the solid waste modification cylinder 5. Under the action of the stirring modification component, the modifier is coated on the outer surface of the solid waste to form a coated dry modification of the multi-component solid waste. Through this modification method, the subsequent filtering and drying processes such as wet modification using acid and alkali modification can be avoided, which can greatly improve the modification efficiency. The treated solid waste falls into the screening frame 4 and can be screened according to the particle size. The screened multi-component solid waste is transported to the corresponding solid waste modification cylinder 5 respectively, that is, the multi-component solid waste ground into small particles can be further screened and refined into different particle levels for modification treatment respectively, which can not only achieve better control of the modification time, but also enable solid wastes of different particle levels to be used for subsequent different deep processing processes.

[0044] The crushing and grinding assembly includes a crushing rotating rod 13, a rotating disk 14, a crushing pressure roller 18 and a crushing blade 19. The crushing rotating rod 13 is rotatably connected in the solid waste crushing tube 1, the rotating disk 14 is fixedly connected to the two ends of the rod body of the crushing rotating rod 13, the two ends of the crushing pressure roller 18 are movably connected to the edge of the rotating disk 14, and the crushing blade 19 is movably connected to the rod body of the crushing rotating rod 13. The crushing rotating rod 13 can rotate in the solid waste crushing tube 1, so that the crushing blade 19 can cut and crush large particles of multi-solid waste, and the crushing pressure roller 18 can be extended outward under the action of centrifugal force, that is, the distance between the crushing pressure roller 18 and the inner wall of the solid waste crushing tube 1 can be reduced, so that the chopped multi-solid waste can be further ground. In addition, as the rotation speed of the crushing rotating rod 13 continues to increase, the centrifugal force exerted on the crushing pressure roller 18 also increases, so that the distance between the crushing pressure roller 18 and the inner wall of the solid waste crushing tube 1 can be continuously reduced, so as to achieve a more refined grinding process for the multi-solid waste.

[0045] There are multiple solid waste modification barrels 5 on both sides of the solid waste crushing tube 1, and a clutch rotating component 55 is arranged under each solid waste modification barrel 5. A driving rotating rod 56 is connected between the multiple solid waste modification barrels 5 located on the same side, and the stirring and modifying components in the multiple solid waste modification barrels 5 located on the same side are connected to the driving rotating rod 56 through the clutch rotating component 55. It can be achieved by driving multiple stirring and modifying components to rotate in the solid waste modification barrel 5 through a driving rotating rod 56, so as to achieve uniform mixing of the multiple solid wastes and the modifiers in the barrel, so that the modifiers can be coated on the outer surface of the multiple solid wastes. At the same time, the clutch rotating component 55 can control whether the stirring and modifying components rotate and stir along with the rotation of the driving rotating rod 56, that is, each stirring and modifying component can be controlled separately, and can be stirred for a corresponding time according to the amount of multiple solid wastes contained in each solid waste modification barrel 5, so as to avoid excessive stirring or incomplete stirring.

[0046] Embodiment 2

[0047] Improvements based on Example 1:

[0048] like Figures 1 to 10 As shown, hydraulic telescopic struts 12 are connected to both sides of the tube wall of the solid waste crushing tube 1, and the bottom ends of the hydraulic telescopic struts 12 are vertically connected to the upper surface of the support bottom plate 6, and the bottom of the solid waste modification tube 5 is fixedly connected to the upper surface of the support bottom plate 6. The solid waste crushing tube 1 and the solid waste modification tube 5 can be fixedly supported and connected through the support bottom plate 6, and the height of the solid waste crushing tube 1 can be adjusted up and down through the hydraulic telescopic struts 12 to meet different usage conditions;

[0049] Furthermore, support bottom rods 7 are vertically connected to the four corners of the lower plate surface of the support base plate 6, and the bottom end of the support bottom rod 7 is rotatably connected to a roller 71, so that the device can be moved by the roller 71, that is, the flexible mobility of the device can be improved, and when moving the device, the solid waste crushing tube 1 can be moved downward by the hydraulic telescopic support rod 12, that is, the overall center of gravity of the device can be lowered to ensure smoother movement. After the device is moved into place, it is only necessary to lift the solid waste crushing tube 1 upward again by the hydraulic telescopic support rod 12.

[0050] Furthermore, the upper end of the solid waste crushing tube 1 is connected to a feed trough 11, and a leakage screen 111 is connected to the tube body portion of the solid waste crushing tube 1 that is connected to the conveying tube 2, so that solid waste raw materials can be added to the solid waste crushing tube 1 through the feed trough 11, and the solid waste after crushing and grinding can be screened through the leakage screen 111, so that the ground small particles of multi-solid waste can leak into the conveying tube 2 for transportation, and the multi-solid waste that cannot be screened continues to be crushed and ground, that is, it can ensure that the multi-solid waste is thoroughly crushed and ground;

[0051] Furthermore, a conveying spiral blade 21 is rotatably connected in the conveying pipe 2, and a pulverizing motor 8 is fixedly connected to one end of the solid waste pulverizing pipe 1. The pulverizing motor 8 is coaxially connected to the pulverizing rotating rod 13 in the solid waste pulverizing pipe 1, and a driving wheel 81 is sleeved on the rotating shaft of the pulverizing motor 8. The conveying spiral blade 21 is coaxially connected to a driven rotating wheel 82 at one end of the outer side of the conveying pipe 2, and a transmission belt 83 is connected between the driving rotating wheel 81 and the driven rotating wheel 82. The pulverizing motor 8 can provide a driving force to the pulverizing rotating rod 13, thereby driving the pulverizing rotating rod 13 to rotate in the solid waste pulverizing pipe 1, thereby achieving pulverization and grinding of multiple solid wastes. At the same time, the conveying spiral blade 21 in the conveying pipe 2 can be driven to rotate in real time through the transmission of the rotating wheel and the belt, that is, the pulverized and ground multiple solid wastes can be transported at the same time, and as the rotation speed of the pulverizing motor 8 increases, the pulverizing and grinding efficiency also increases. At this time, the rotation speed of the conveying spiral blade 21 also increases, which can ensure that the transportation efficiency of the multiple solid wastes is also improved, that is, the conveying pipe 2 can always meet the transportation requirements;

[0052] It should be noted that the diameter of the driven wheel 82 is greater than the diameter of the driving wheel 81, that is, the decelerated rotation of the conveying spiral blade 21 can be achieved, and the conveying spiral blade 21 can be kept at a reasonable rotation speed while the conveying pipe 2 meets the conveying requirements, which can avoid the situation where the conveying spiral blade 21 rotates too fast and causes serious mechanical wear, and the diameter ratio of the driven wheel 82 to the driving wheel 81 is further optimized to 2.5:1.

[0053] Furthermore, a plurality of positioning blocks 15 are evenly distributed on the inner wall edge of the rotating disk 14, and a movable connecting rod 16 is movably inserted in the positioning block 15. The outer ends of the movable connecting rod 16 are rotatably connected to the two ends of the crushing roller 18 respectively, and the inner end of the movable connecting rod 16 is sleeved with a compression spring 17. The inner end of the movable connecting rod 16 is fixedly connected to the limiting block 112, and the compression spring 17 is abutted between the limiting block 112 and the positioning block 15, so that when the crushing roller 18 is subjected to the effect of centrifugal force, the movable connecting rod 16 can be pulled outward, and the compression spring 17 will be compressed at this time, that is, the compression spring 17 will have a certain anti-centrifugal force on the crushing roller 18, so that when the speed of the crushing rotating rod 13 is continuously increased, the crushing roller 18 can continue to slowly extend outward, and the centrifugal force exerted on the crushing roller 18 and the compression spring 17 The applied counter-centrifugal force remains balanced, so that when the pulverizing shaft 13 maintains a specific rotation speed, the pulverizing roller 18 can maintain a stable connection position, that is, it can achieve specific grinding of the solid waste; it should be noted that three positioning blocks 15 are arranged at the edge of the inner wall of the turntable 14, and the compression springs 17 sleeved on the rod body of each pulverizing shaft 13 have different elastic coefficients. The solid waste can be crushed and crushed by setting three groups of pulverizing rollers 18, and because the elastic coefficients of the compression springs 17 are different, when the pulverizing shaft 13 maintains a specific rotation speed, the compression amplitude of the compression spring 17 is also different, and then the amplitudes of the outward extension of the multiple pulverizing rollers 18 can also be different, that is, the pulverizing shaft 13 can grind the solid waste with different crushing intensities when rotating, and can grind the solid waste according to various working conditions.

[0054] Furthermore, a plurality of blade connection seats 110 are fixedly connected to the rod body of the crushing rotating rod 13, and the blade connection seats 110 are evenly distributed on the rod body of the crushing rotating rod 13, and the blade connection seats 110 are rotatably connected to the crushing blade 19, so that when the crushing rotating rod 13 rotates, the crushing blade 19 can also be affected by the centrifugal force and rotate with the crushing rotating rod 13, thereby cutting and crushing large particles or large blocks of multi-solid waste for further grinding treatment, and because the crushing blade 19 is movably connected to the blade connection seat 110, when the crushing blade 19 cuts the multi-solid waste, if the multi-solid waste particles are too large to be directly cut, the crushing blade 19 will rotate at an angle during cutting, that is, the crushing blade 19 will not be damaged; it should be noted that the blade connection seats 110 can be arranged in a ring shape on the rod body of the crushing rotating rod 13 in a plurality of groups, and the blade connection seats 110 can also be arranged in a spiral shape on the rod body of the crushing rotating rod 13.

[0055] Furthermore, the discharge end of the conveying pipe 2 is connected to the crushed solid waste discharge pipe 22, the upper end of the three-way distribution pipe 3 is connected to the crushed solid waste discharge pipe 22, and the joint between the three-way distribution pipe 3 and the crushed solid waste discharge pipe 22 is sleeved with an outer sleeve 31. The three-way distribution pipe 3 is rotatably connected to the crushed solid waste discharge pipe 22 through the outer sleeve 31, so that the three-way distribution pipe 3 can be rotated, and then when the solid waste crushing pipe 1 needs to be moved downward, the three-way distribution pipe 3 can be rotated to make the other two pipe openings of the three-way distribution pipe 3 parallel to the screening frame 4, so as to avoid motion interference when the solid waste crushing pipe 1 moves downward;

[0056] Furthermore, a fixed baffle 32 is fixedly connected to the pipe mouth of the crushed solid waste discharge pipe 22, and a movable baffle 33 is fixedly connected to the upper end pipe mouth of the three-way distribution pipe 3, the fixed baffle 32 and the movable baffle 33 are placed together, and leakage holes 34 are opened on the plate bodies of the fixed baffle 32 and the movable baffle 33, and the movable baffle 33 can be driven to rotate relative to the fixed baffle 32 by rotating the three-way distribution pipe 3, so that when the other two pipe mouths of the three-way distribution pipe 3 are rotated to just above the screening frame 4, the leakage holes 34 opened by the fixed baffle 32 and the movable baffle 33 overlap with each other, thereby ensuring that the transported multi-solid waste can pass through the leakage holes 34 and fall into the screening frames 4 on both sides respectively; it should be noted that two leakage holes 34 are opened on the plate bodies of the fixed baffle 32 and the movable baffle 33, and the two leakage holes 34 opened by the movable baffle 33 correspond to the two discharge pipe mouths of the three-way distribution pipe 3 respectively.

[0057] like Figure 1 , Figure 2 and Fig.11 As shown, a first mesh screen plate 41, a second mesh screen plate 42 and a guide plate 43 are arranged in the screening frame 4, and the first mesh screen plate 41, the second mesh screen plate 42 and the guide plate 43 are connected together in an inclined state in sequence, and the upper surfaces of the first mesh screen plate 41, the second mesh screen plate 42 and the guide plate 43 are on the same inclined plane, and the mesh diameter of the first mesh screen plate 41 is smaller than the mesh diameter of the second mesh screen plate 42, so that the multi-component solid waste falling into the screening frame 4 can be further screened, and the multi-component solid waste of different particle levels after screening can be dropped into the corresponding solid waste modification cylinder 5, so as to realize further screening optimization of the multi-component solid waste and then perform modification treatment. It should be noted that the outer wall of the screening frame 4 can also be connected to a vibration motor to improve the screening efficiency;

[0058] Furthermore, the bottoms of the first mesh sieve plate 41 and the second mesh sieve plate 42 are connected to a collecting hopper 44, and the bottom outlets of the collecting hopper 44 are respectively located directly above two of the solid waste modification cylinders 5, and the inclined end of the guide plate 43 is located directly above the other solid waste modification cylinder 5, which ensures that the screened solid waste can be collected by the collecting hopper 44 and smoothly fall into the corresponding solid waste modification cylinder 5, while the solid waste that fails to pass the screen will be uniformly dropped into the last solid waste modification cylinder 5. It should be noted that several mesh sieve plates with different mesh diameters can also be connected to the screening frame 4, and the lower surface of each mesh sieve plate is connected to the collecting hopper 44. Several solid waste modification cylinders 5 can be provided according to the number of mesh sieve plates, and each solid waste modification cylinder 5 is located directly below the collecting hopper 44.

[0059] like Figure 1 , Figure 2 , Figures 12 to 17 As shown, the stirring and modifying assembly includes a stirring rotating rod 51, a stirring spiral blade 52 and an inclined material guide tube 53. The stirring spiral blade 52 is fixedly connected to the rod body of the stirring rotating rod 51. The stirring rotating rod 51 is rotatably connected to the solid waste modification barrel 5. The stirring spiral blade 52 can be driven by the stirring rotating rod 51 to rotate, thereby stirring the multi-component solid waste and the modifying agent in the barrel upward, that is, the multi-component solid waste and the modifying agent in the barrel are stirred in an upward flipping manner, which can ensure more uniform stirring. It should be noted that the barrel wall of the solid waste modification barrel 5 can also be installed with an electric heating wire to increase the temperature of the multi-component solid waste during the modification process, that is, the modification rate can be further accelerated;

[0060] Furthermore, the inclined material guide tube 53 is sleeved on the outside of the stirring spiral blade 52, and a limiting connecting rod 54 is connected between the inclined material guide tube 53 and the inner wall of the solid waste modification cylinder 5. The inclined surface of the tube body of the inclined material guide tube 53 is inclined downward, so that when the stirring spiral blade 52 stirs the multi-solid waste and modifier in the cylinder, the multi-solid waste and modifier located below the inclined material guide tube 53 can be stirred upward, while the multi-solid waste and modifier on the periphery can fall downward along the inclined surface of the tube body of the inclined material guide tube 53 and be supplemented to the bottom of the inclined material guide tube 53, which can ensure that when the multi-solid waste and modifier in the cylinder are turned over, all the multi-solid waste and modifier can be turned over and stirred, thereby further improving the stirring efficiency and ensuring the uniform coating of the multi-solid waste by the modifier after stirring.

[0061] Furthermore, a discharge hole 510 is provided at the bottom end of the solid waste modification cylinder 5, and the discharge hole 510 is connected to a modified solid waste discharge pipe 511, and the modified solid waste discharge pipe 511 penetrates the supporting bottom plate 6. An electromagnetic gate valve 512 is installed on the body of the modified solid waste discharge pipe 511, and the modified solid waste can be discharged from the cylinder through the modified solid waste discharge pipe 511, and the modified solid waste discharge pipe 511 can be opened and closed by the electromagnetic gate valve 512;

[0062] Furthermore, a scraper 58 is connected to the rod body of the stirring rod 51, and the scraper 58 is placed on the inner wall of the bottom of the solid waste modification cylinder 5. A material guide slope 59 is provided at the connection position between the scraper 58 and the stirring rod 51. During the stirring process, the solid waste and the modifier at the bottom of the cylinder can be scraped up by the scraper 58 to ensure uniform stirring and mixing. When the multi-solid waste in the cylinder is discharged, as the stirring rod 51 rotates, the scraper 58 can scrape the multi-solid waste remaining at the bottom of the solid waste modification cylinder 5, and cooperate with the action of the material guide slope 59 to enable the multi-solid waste to gather at the discharge hole 510, that is, it can ensure that the multi-solid waste in the cylinder is completely discharged.

[0063] Furthermore, the clutch rotating assembly 55 includes a housing 551, a worm 552 and a worm wheel 553. The housing 551 is covered on the outside of the worm 552 and the worm wheel 553, and the housing 551 is connected to the lower plate surface of the supporting bottom plate 6. The worm 552 is meshed with the worm wheel 553. The shaft of the driving rotating rod 56 passes through the housing 551. The shaft of the worm 552 is provided with a through cavity. The worm 552 is sleeved on the shaft of the driving rotating rod 56 located in the housing 551 through the through cavity. The stirring rotating rod 51 is provided in the housing 551. One end below the support bottom plate 6 is fixedly connected to the worm gear 553, and the lower plate surface of the support bottom plate 6 is also fixedly connected to a stirring drive motor 57, which is coaxially connected to the driving rotating rod 56, and can be driven by the stirring drive motor 57 to rotate. When the driving rotating rod 56 is fixedly connected to the worm 552, the meshing transmission of the worm 552 and the worm gear 553 can be achieved, that is, the driving force can be provided to the stirring rotating rod 51, so that the stirring and modifying assembly can rotate in the solid waste modification cylinder 5;

[0064] Furthermore, a gap is left between the worm 552 and the driving rotating rod 56, sealed bearings 555 are connected between the two ends of the worm 552 and the rod body of the driving rotating rod 56, a plurality of teeth 556 are integrally connected on the inner wall of the inner cavity of the worm 552 and the rod body of the driving rotating rod 56 located in the shell 551, and the gap left between the worm 552 and the driving rotating rod 56 is filled with magnetorheological fluid 557, and a strong electromagnet 554 is fixedly connected to the inner wall of the shell 551, so that when the strong electromagnet 554 is not energized, the magnetorheological fluid 557 is In the fluid state, the worm 552 is rotationally connected to the driving rotating rod 56. At this time, the rotation of the driving rotating rod 56 will not drive the worm 552 to rotate accordingly. When the powerful electromagnet 554 is energized, the magnetorheological fluid 557 will be converted into a solid state, and the action of the teeth 556 can make the worm 552 and the driving rotating rod 56 fixedly connected. At this time, the rotation of the driving rotating rod 56 can drive the worm 552 to rotate accordingly. Therefore, the rotation control of the stirring and modifying components in each solid waste modification cylinder 5 can be achieved by controlling the on and off of the powerful electromagnet 554.

[0065] Working principle: The multi-solid waste raw materials are transported to the solid waste crushing tube 1 through the feeding trough 11, and the multi-solid waste is crushed and ground through the crushing and grinding assembly to process the multi-solid waste into small particles. The crushing blade 19 can cut and crush the large particles of multi-solid waste through the rotation of the crushing rotating rod 13 in the solid waste crushing tube 1, and the crushing roller 18 can be extended outward under the action of centrifugal force, that is, the distance between the crushing roller 18 and the inner wall of the solid waste crushing tube 1 can be reduced, so that the chopped multi-solid waste can be further ground. As the rotation speed of the crushing rotating rod 13 continues to increase, the centrifugal force exerted on the crushing roller 18 also increases, so that the distance between the crushing roller 18 and the inner wall of the solid waste crushing tube 1 can be continuously reduced, so that the multi-solid waste can be ground more finely, and then the processed multi-solid waste can be transported to the solid waste modification tube. 5, by adding the modifier into the solid waste modification cylinder 5, and under the action of the stirring and modifying component, the modifier is coated on the outer surface of the multi-component solid waste, and the stirring spiral blade 52 is driven to rotate by the stirring rod 51, so that the multi-component solid waste and the modifier in the cylinder can be stirred upward, that is, the multi-component solid waste and the modifier in the cylinder are stirred upward, which can ensure that the stirring is more uniform, so as to form a coated dry modification of the multi-component solid waste, and the treated multi-component solid waste falls into the screening frame 4 for particle size screening, and the screened multi-component solid waste is transported to the corresponding solid waste modification cylinder 5, that is, the multi-component solid waste ground into small particles can be further screened and refined into different particle levels for modification treatment, which can not only achieve better control of the modification time, but also enable the multi-component solid waste of different particle levels to be used for subsequent different deep processing processes.
