[0002] Gangue is solid waste generated during coal mining and washing. Large-scale storage of gangue not only wastes precious land resources, but may also spontaneously combust and pollute the environment. However, gangue is also an important secondary resource that can be used to produce building materials, generate electricity, and extract rare metals, etc., to achieve resource recycling. However, the amount of gangue consumed by the above methods is small, resulting in the speed of gangue consumption being lower than the speed of gangue output, that is, the problem of gangue accumulation occupying land resources has not been completely solved.

[0003] my country has actively explored various ways to effectively utilize coal gangue, aiming to reduce environmental pollution while promoting the development of a circular economy. Since the elemental composition of coal gangue is similar to that of soil, but the content is different, coal gangue can also be used as a soil conditioner to increase soil fertility. Through these measures, not only can the environmental problems caused by coal gangue be solved, but waste can also be turned into treasure to create new economic value.

[0004] However, the existing methods for applying coal gangue to improve soil mostly use it in the form of solid coal gangue, which needs to be transported by vehicles during use, resulting in high transportation costs, low transportation efficiency and high transportation difficulty. Therefore, the existing methods cannot be well applied on a large scale as a soil conditioning and improvement component. Summary of the invention

DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0025] A gangue-based organic carbon soil conditioner, which is composed of the following raw materials in percentage by weight: gangue; catalytic decomposition biological enzymes, in a proportion of 0.005%-0.5%, for decomposing macromolecular carbon into small molecular carbon that is beneficial to plant absorption; heavy metal-resistant bacteria, in a proportion of 0.005%-0.5%, for converting highly toxic heavy metals into low-toxic heavy metals; sulfate or slaked lime, in a proportion of 0.5%-2%, for adjusting soil pH; bio-based CMC cellulose, in a proportion of 0.3%-2%, for slow-release of nutrients and increase of viscosity, which is beneficial to prevent segregation during pipeline transportation; TWEEN-80 surfactant, in a proportion of 0.1%-1%, for retaining moisture and increasing the activity of carbon fertilizer.

[0026] Coal gangue is a mixture of microparticles and granules. Through the compounding of various particle sizes, the physical structure of the soil is improved and the air permeability of the soil is ensured.

[0027] The above scheme aims to solve the problem that the existing utilization rate of coal gangue is lower than the output rate of coal gangue, resulting in the accumulation of coal gangue and the occupation of land resources. By mixing coal gangue with other substances to prepare soil conditioners, the accumulated coal gangue can be utilized in large quantities to alleviate the problem of land resource occupation caused by the accumulation of coal gangue; the coal gangue particles and particles can be broken into small round particles by mechanical equipment such as crushers or sand making machines, which is conducive to pipeline fluidization transportation; by crushing the coal gangue into a state of composite large and small particles, it is beneficial to improve the soil structure and restore it to a loose and porous state with appropriate compactness and stability, which is beneficial to the soil to retain moisture and nutrients while resisting weathering and erosion.

[0028] The preparation steps are as follows: S1: crush the coal gangue into a state of mixed large and small particle sizes by a jaw crusher and a double-roll sand making machine in turn; S2: then mix the catalytic decomposition enzyme, heavy metal-resistant bacteria, sulfate or slaked lime, bio-based CMC cellulose and TWEEN-80 surfactant in proportion, and use coal gangue particles and particles to make up the rest to form an organic carbon soil conditioner; S3: add an appropriate amount of water and a selected thickener to the organic carbon soil conditioner to prepare a fluid medium with high stability that is not prone to segregation and sedimentation.

[0029] A fluidized device for preparing a gangue-based organic carbon soil conditioner. Based on the above-mentioned gangue-based organic carbon soil conditioner, please refer to Figure 1-Figure 4 , including: a mounting seat 1; a cover shell 2, mounted on the mounting seat 1, a driving roller group 201 mounted on the mounting seat 1 is rotatably connected in the cover shell 2, an adjusting roller group 202 slidably connected to the mounting seat 1 is slidably and rotatably connected in the cover shell 2, and the driving roller group 201 and the adjusting roller group 202 cooperate to squeeze and crush the coal gangue; a feeding shell 3, mounted on the mounting seat 1, the feeding shell 3 is located above the cover shell 2, and is used to feed materials into the cover shell 2, and the feeding shell 3 is fixedly connected with a first moving A force element 301, wherein the first power element 301 is provided with an eccentric block 302; a weight block 4 is installed in the eccentric block 302, a sliding cavity 303 is provided in the eccentric block 302, the weight block 4 slides in a sealed manner in the sliding cavity 303, and a control flow channel 401 connected to the sliding cavity 303 is provided in the eccentric block 302; a detection component is arranged at a position of the cover shell 2 close to the feeding shell 3, and is used to detect the volume of coal gangue accumulated between the active roller group 201 and the adjusting roller group 202.

[0030] Both the active roller group 201 and the adjusting roller group 202 are composed of a crushing roller and two rectangular seats rotatably connected to the crushing roller. The crushing roller on the active roller group 201 is rotatably connected to the cover shell 2, and the rectangular seat on the active roller group 201 is connected to the mounting seat 1 by bolts; the crushing roller on the adjusting roller group 202 is slidably and rotatably connected to the cover shell 2, and the rectangular seat on the adjusting roller group 202 is slidably connected to the mounting seat 1.

[0031] In the above scheme, it is intended to solve the problem that when using a double-roller sand making machine to crush coal gangue, the uneven particle size distribution of the coal gangue can easily lead to material piling in the double-roller sand making machine, resulting in serious wear of the double-roller sand making machine; transmission fluid can be stored in the control flow channel 401, and power is subsequently transmitted through the transmission fluid; a feed shell 203 can be installed above the cover shell 2 to facilitate guiding the coal gangue sprinkled from the feed shell 3 into the cover shell 2, thereby reducing the probability of coal gangue spilling out of the cover shell 2; the feed shell 3 and the mounting seat 1 can be connected by a spring or other elastic material to reduce the impact of the vibration of the feed shell 3 on the mounting seat 1; the first power element 301 can be a component with the same function such as an electric motor and a hydraulic motor.

[0032] The position of the weight block 4 is changed by controlling the flow of the transmission fluid in the flow channel 401, thereby changing the position of the center of gravity of the eccentric block 302. When the gangue is accumulated on the active roller group 201 and the adjusting roller group 202, the detection component detects that the gangue is accumulated, and controls the weight block 4 to move toward the direction close to the rotation axis of the eccentric block 302 through the transmission fluid, so that the distance between the center of gravity of the eccentric block 302 and the weight block 4 as a whole and the rotation axis of the eccentric block 302 is reduced, that is, the eccentric distance of the eccentric block 302 and the weight block 4 as a whole is reduced, so that the eccentricity of the eccentric block 302 and the weight block 4 is reduced. The centrifugal force on the eccentric block 302 and the weight block 4 as a whole during rotation is reduced, and thus the amplitude of the vibration generated by the eccentric block 302 during rotation is reduced, so that the volume of the coal gangue put into the cover shell 2 by the feeding shell 3 per unit time is reduced. In this way, the coal gangue accumulated on the active roller group 201 and the adjusting roller group 202 is processed first under a limited crushing speed, the volume of the coal gangue accumulated on the active roller group 201 and the adjusting roller group 202 is reduced, and the wear of the active roller group 201 and the adjusting roller group 202 by the coal gangue during rotation is reduced.

[0033] See also Figure 5The detection component includes: a detection frame 5, which is arranged on the cover shell 2, and a rectangular through hole 501 is arranged on the cover shell 2. The detection frame 5 slides in the rectangular through hole 501, and the detection frame 5 is located above the active roller group 201 and the adjusting roller group 202, and is used to detect the height of the coal gangue accumulated between the active roller group 201 and the adjusting roller group 202; a second power element 6, which is installed on the detection frame 5 and is located outside the cover shell 2; a friction member 7, which is installed on the second power element 6, and a friction part 701 is arranged on the friction member 7, and the friction part 701 is frictionally matched with the cover shell 2; a limit assembly, which is arranged on the detection frame 5, and is used to reduce the extrusion force of the detection frame 5 on the coal gangue accumulated between the active roller group 201 and the adjusting roller group 202; a transmission assembly, which is arranged on the detection frame 5, and is used to adjust the position of the weight 4 according to the detection result of the detection frame 5.

[0034] The radius of the friction portion 701 is equal to the distance between the center of the friction member 7 and the housing 2 , and the radius of other positions of the friction member 7 is smaller than the distance between the center of the friction member 7 and the housing 2 .

[0035] In the above scheme, the purpose is to detect the accumulation of coal gangue between the active roller group 201 and the adjusting roller group 202 through the position of the detection frame 5; the cross-section of the detection frame 5 is roughly in the shape of a "mouth", and the width of the "mouth" on the detection frame 5 is greater than the gap between the active roller group 201 and the adjusting roller group 202, so as to reduce the impact on the falling path of the coal gangue; the two ends of the detection frame 5 can be fixedly connected to symmetrically distributed baffles 502, and the baffles 502 are used to block the adjacent rectangular through holes 501 to prevent the coal gangue in the cover 2 from entering the rectangular through holes 501 and hindering the movement of the detection frame 5; the second power element 6 can be a component with the same function such as an electric motor and a hydraulic motor; the material of the friction member 7 can be a material with a high friction coefficient such as hard rubber.

[0036] The friction member 7 is driven to rotate by the second power element 6, so that the friction part 701 is intermittently in contact with the cover shell 2. When the two are in contact, as the friction member 7 rotates, the friction force between the friction part 701 and the cover shell 2 is used to drive the detection frame 5 to move up a certain distance until the friction part 701 loses contact with the cover shell 2. The detection frame 5 then falls under the action of its gravity until the detection frame 5 is reset or contacts with the accumulated coal gangue. At this time, the detection frame 5 stops moving down, and then the above steps are repeated to make the detection frame 5 intermittently move up and then fall, so that the detection frame 5 can always be located above the coal gangue. In this way, the distance between the detection frame 5 and the initial time when it stops falling is the thickness of the accumulated coal gangue.

[0037] See also Figure 5 and Figure 6The limiting assembly includes: an extrusion bar 8, which is slidably connected in the detection frame 5, and the extrusion bar 8 protrudes from the lower side of the detection frame 5, so that the extrusion bar 8 contacts the coal gangue before the detection frame 5; an elastic member 9, which is fixed to the position of the extrusion bar 8 near the rectangular through hole 501, and is used to provide support and reset force for the extrusion bar 8, and the elastic member 9 is slidably connected to the detection frame 5; an elliptical piston 10, which is fixed to the elastic member 9, and an extrusion chamber 101 is provided in the detection frame 5, and the elliptical piston 10 slides in the extrusion chamber 101 in a sealed manner; symmetrically distributed limiting blocks 11, which are sealed and slidably connected in the detection frame 5, and a tension spring is fixed between the limiting blocks 11 and the detection frame 5, and the symmetrically distributed limiting blocks 11 cooperate with the detection frame 5 to form a limiting chamber 111, and the limiting chamber 111 is connected to the extrusion chamber 101, and two symmetrical groups of limiting grooves 112 are provided near the rectangular through hole 501 on the cover shell 2, and the limiting blocks 11 cooperate with adjacent limiting grooves 112 in a limiting manner.

[0038] In the above scheme, the purpose is to reduce the squeezing force of the detection frame 5 on the accumulated coal gangue, to prevent the detection frame 5 from squeezing the coal gangue when it contacts the accumulated coal gangue, causing the squeezing force of the coal gangue on the active roller group 201 and the adjusting roller group 202 to increase, so that the wear of the active roller group 201 and the adjusting roller group 202 increases; the squeezing strips 8 can be two symmetrically distributed, and the distances between the active roller group 201 and the adjusting roller group 202 and the adjacent squeezing strips 8 are equal, which is used to improve the sensitivity of the movement of the transmission limit block 11 of the squeezing strip 8, and the number of subsequent elastic members 9, elliptical pistons 10, limit blocks 11 and limit grooves 112 changes synchronously; the squeezing strip 8 can correspond to two symmetrically distributed elastic members 9, and the elastic member 9 on one side is aligned with the adjacent elliptical piston 1 0 is fixed, and the elastic member 9 on the other side simply provides the power for resetting the adjacent extrusion strip 8; the elastic member 9 can be made of elastic material of plastic or metal. Initially, the elastic member 9 is in a bent state. The minimum distance between the fixed position of the elastic member 9 and the adjacent extrusion strip 8 and the end of the adjacent extrusion strip 8 is less than the length of the elastic member 9 when it is unfolded. When the extrusion strip 8 moves upward relative to the detection frame 5, the elastic member 9 is squeezed to a straight state, and in this process, the end of the elastic member 9 moves along the detection frame 5; the opposite sides of the two symmetrically distributed limit blocks 11 are both inclined surfaces facing obliquely upward, so that when the limit block 11 cooperates with the adjacent limit groove 112, it can only move upward in one direction. Without changing the above scheme, the limit block 11 and the adjacent limit groove 112 can be replaced by a structure similar to a ratchet pawl.

[0039] When the detection frame 5 falls, the detection frame 5 drives the extrusion bar 8 to move downward, and the distance between the extrusion bar 8 and the accumulated coal gangue gradually decreases. When the extrusion bar 8 contacts the coal gangue, the extrusion bar 8 stops moving, and then the detection frame 5 continues to move downward, and the extrusion bar 8 moves up relative to the detection frame 5 and enters the detection frame 5. In this process, the extrusion bar 8 drives the elliptical piston 10 to move through the elastic member 9, and the elliptical piston 10 squeezes the transmission fluid in the adjacent extrusion chamber 101 into the limit chamber 111. The transmission fluid in the limit chamber 111 pushes the symmetrically distributed limit blocks 11 to move backward and stretch the adjacent tension springs. The limit blocks 11 enter the adjacent limit grooves 112 and The detection frame 5 is limited. At this time, the position of the detection frame 5 can reflect the height of the coal gangue accumulated between the active roller group 201 and the adjusting roller group 202. Then, when the detection frame 5 moves up again, the limit block 11 is squeezed by the adjacent limit groove 112 and retracted into the limit cavity 111 to reset. At the same time, the extrusion bar 8 is reset relative to the detection frame 5 under the action of the elastic member 9. In this way, the limit block 11 is driven by the extrusion bar 8 to move and limit the detection frame 5, preventing all gravity on the detection frame 5 from being squeezed onto the coal gangue accumulated between the active roller group 201 and the adjusting roller group 202, thereby reducing the wear of the coal gangue on the active roller group 201 and the adjusting roller group 202.

[0041] The arc length of the friction portion 701 is smaller than the height of the telescopic member 15 .

[0042] The elastic force of the spring between the sealing piston 14 and the transmission cylinder 12 is greater than the centrifugal force exerted on the weight 4 .

[0043] In the above scheme, the purpose is to control the movement of the weight 4 through the transmission fluid according to the situation of coal gangue accumulation detected by the above-mentioned detection component; the arc-shaped liquid bag 18 can be made of elastic material, or the hydraulic telescopic rod 17 is a spring telescopic rod, which is used to drive the sealing plate 16 to reset; the position where the second connecting piece 182 is rotatably connected to the friction piece 7 can be made of hard material, which is used to prevent the second connecting piece 182 from being entangled under the drive of the friction piece 7, and the position where the second connecting piece 182 is rotatably connected to the friction piece 7 can be fixed to the detection frame 5 through a bracket, which is used to improve the stability of the second connecting piece 182 when the friction piece 7 rotates; the position where the first connecting piece 161 is rotatably connected to the eccentric block 302 can be made of hard material, and the position where the first connecting piece 161 is rotatably connected to the eccentric block 302 can be fixed to the lower side of the feeding shell 3 through a bracket, which is used to improve the stability of the first connecting piece 161 when the eccentric block 302 rotates; the telescopic piece 15 can be a bellows or other parts with a contraction function, which are used to make the telescopic piece 15 move with the sealing piston 14.

[0044] During the upward movement of the detection frame 5, the detection frame 5 drives the piston rod 13 to move upward together. The piston rod 13 squeezes the sealing piston 14 upward through the transmission fluid in the transmission chamber 141, and compresses the spring adjacent to the telescopic member 15 and the upper side of the sealing piston 14. When the detection frame 5 falls to contact with the coal gangue, the position of the detection frame 5 changes relative to the initial position. Similarly, the position of the piston rod 13 moves upward relative to the initial position. When the arc-shaped liquid capsule 18 contacts the cover shell 2, the cover shell 2 squeezes the arc-shaped liquid capsule 18, so that the transmission fluid in the arc-shaped liquid capsule 18 passes through the cover shell 2. The connecting flow channel 181 and the second connecting piece 182 flow into the hydraulic telescopic rod 17, the telescopic end of the hydraulic telescopic rod 17 extends out and drives the blocking plate 16 to move, and the blocking plate 16 releases the blockage of the first connecting piece 161. At this time, the sealing piston 14 moves down and resets under the action of its adjacent spring, and squeezes the transmission fluid in the transmission chamber 141, so that the transmission fluid enters the first connecting piece 161 through the telescopic piece 15 and the transfer chamber 121, and the transmission fluid in the first connecting piece 161 drives the weight block 4 to move, thereby realizing the adjustment of the position of the weight block 4.

[0045] As the friction member 7 rotates, the arc-shaped liquid bag 18 loses contact with the cover shell 2, and then the arc-shaped liquid bag 18 is reset and the telescopic end of the transmission hydraulic telescopic rod 17 contracts, so that the blocking plate 16 blocks the first connecting member 161 again, thereby completing the adjustment of the position of the counterweight 4.

[0046] See also Figure 8 and Fig. 9The delay assembly includes: a flow limiting plate 19, which is fixed to the transmission cylinder 12 and located in the transfer chamber 121. The flow limiting plate 19 is provided with a plurality of flow limiting holes 191, and a check valve 192 is installed in some of the flow limiting holes 191.

[0047] In the above scheme, it is intended to delay the change of the feeding flow rate of the feed shell 3 when the volume of the coal gangue accumulated between the active roller group 201 and the adjusting roller group 202 gradually decreases, so that the accumulated coal gangue is quickly crushed, and the wear caused by the coal gangue to the active roller group 201 and the adjusting roller group 202 is reduced; the number of the limiting flow holes 191 can be two or more, and the number of the limiting flow holes 191 selected here is two, and a one-way valve 192 is installed in one of the limiting flow holes 191; the one-way valve 192 flows from bottom to top, and is used for adjusting the position of the weight block 4 through the transmission fluid, and the transmission fluid flows through the two limiting flow holes 191, and when the weight block 4 is reset When the transmission fluid flows only through a single limited flow hole 191, the volume of the transmission fluid flowing in a single time is different under the condition of the same single connection time (i.e., the time for the blocking plate 16 to release and re-block the first connecting piece 161). In this way, the weight block 4 can be quickly adjusted when the coal gangue is accumulated. When the volume of the accumulated coal gangue gradually decreases, the weight block 4 is slowly reset, so that the feeding speed of the feeding shell 3 is maintained at a state lower than the crushing speed of the device. In this way, the volume of the coal gangue accumulated between the active roller group 201 and the adjusting roller group 202 is quickly reduced, thereby shortening the time for the coal gangue to wear the active roller group 201 and the adjusting roller group 202.

[0048] The specific operation of using the device to crush coal gangue is as follows: first, the detection component is started, so that the detection frame 5 intermittently moves up and then falls down, and the worker uses a forklift or a conveyor belt to continuously put the coal gangue processed by the jaw crusher into the feeding shell 3, so that the feeding shell 3 stably puts the coal gangue into the cover shell 2, and the coal gangue is crushed by the opposite rotation of the active roller group 201 and the adjusting roller group 202. When the particle size of the coal gangue falling between the active roller group 201 and the adjusting roller group 202 is too large, the device crushes the coal gangue The speed slows down, causing the coal gangue to accumulate between the active roller group 201 and the adjusting roller group 202. The detection component detects the volume of the coal gangue accumulation, and adjusts the position of the weight block 4 through the transmission component, so that the center of gravity of the eccentric block 302 and the weight block 4 as a whole is offset, reducing the amplitude of the feeding shell 3, and reducing the feeding amount of the feeding shell 3 per unit time. In this way, the accumulated coal gangue is crushed first under the condition of limited crushing speed, reducing the wear of the device, and at the same time, there is no need to actively stop the machine, thereby improving production efficiency.
