Description

Technical Field

[0001] The present invention relates to the technical field of fluidized solidified soil, and in particular to a multi-solid waste fluidized solidified soil and a preparation device thereof. Background Art

[0002] Fluidized solidified soil is a filling material with good fluidity, which is made of soil and curing agent as the main raw materials. It is mixed with water to obtain a filling material with good fluidity. It is usually used in engineering projects such as foundation pit backfilling and foundation treatment. At present, when preparing fluidized solidified soil, industrial solid waste, construction waste, etc. are usually added to the soil as raw materials to reuse the waste. Compared with the traditional manual compaction backfilling method, fluidized solidified soil does not need to be compacted because it has high fluidity and can be filled to the required position and then hardened naturally quickly. While improving the construction efficiency, its density and strength can also be adjusted according to specific engineering needs during actual use. Therefore, fluidized solidified soil is widely used in engineering projects such as foundation pit backfilling and foundation treatment. However, because fluidized solidified soil relies on soil with high viscosity and strong water absorption capacity as the main component, in order to achieve ideal fluidity, the amount of mixing water actually used exceeds the amount required for the hydration of the curing agent. Therefore, in the subsequent drying process, the fluidized solidified soil is prone to large shrinkage and cracks, which seriously affects the quality of the project. Summary of the invention

[0016] When the pressure plate is blocked by stones and cannot move further downward, the connecting plate is disconnected from the fixed column, so that the fixed column can no longer drive the connecting plate to move downward, thereby preventing the two pressure plates from continuing to move downward after contacting the stones, causing the two pressure plates and the screen plate to deform due to pressure, thereby affecting the normal use of the two pressure plates and the screen plate.

[0017] The first cleaning block and the second cleaning block are used to clean soft impurities such as plastic bags attached to the sieve plate, thereby reducing the probability of such impurities falling into the mixing tank, thereby reducing the probability of such impurities being entangled on the mixing module in the mixing tank, ensuring the normal use of the mixing module, and at the same time reducing the impact of such impurities on the formation of the internal structure of the fluidized solidified soil, thereby ensuring the overall strength and stability of the prepared fluidized solidified soil.

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Industrial waste slag includes one or more of granulated blast furnace slag, fly ash, and steel slag; The specific surface area of ​​granulated blast furnace slag shall not be less than 400m 2 / kg; The residue of fly ash after sieving through a 45μm square hole sieve shall not exceed 30%; The specific surface area of ​​steel slag shall not be less than 350m 2 / kg; The mineral components of industrial by-product gypsum include CaSO4·2H2O and CaSO4; Industrial by-product gypsum is desulfurized gypsum; The preparation of fluidized solidified soil includes the following steps: The construction waste soil is crushed to a particle size not exceeding 5 mm, and then mixed evenly with polystyrene particles, tung oil and water to obtain a mixed slurry A with a moisture content of not less than 50%; Industrial waste residue, cement, industrial by-product gypsum, and activator are mixed with water to obtain a curing agent slurry; The obtained curing agent slurry, compound water reducing agent and mixed slurry A are stirred evenly to obtain fluidized cured soil.

[0023] Example 2: Based on Example 1, a multi-solid waste fluidized solidified soil preparation device is provided. Figure 1-Figure 3 As shown, the preparation device includes: a fixed frame 1; a stirring tank 2, which is fixedly connected to the fixed frame 1, a stirring module is arranged in the stirring tank 2, and a slurry discharge port is arranged on the lower side of the stirring tank 2; a feed shell 3, which is fixedly connected to the upper side of the fixed frame 1, and the feed shell 3 is fixedly connected to and communicated with the stirring tank 2; a sieve plate 4, which is fixedly connected to the upper side of the feed shell 3; a guide shell 5, which is fixedly connected to the upper side of the fixed frame 1 through a connecting piece, and the guide shell 5 is located above the feed shell 3; an electric rotating shaft 6, which has two symmetrically distributed ones, both of which are arranged on the guide shell 5, and the electric rotating shaft 6 is fixedly connected with a pressing plate 7, and the pressing plate 7 is located in the guide shell 5 and slides; an electric push rod 8, which is fixedly connected to one side of the guide shell 5, and a connecting plate 9 is arranged at the telescopic end of the electric push rod 8, and the connecting plate 9 is rotatably connected to the two electric rotating shafts 6.

[0024] In the above scheme, the stirring module is an existing device, which is not fully shown in the figure. The stirring module can be selected as a combination of a stirring blade and a driving motor, and the stirring module is connected to the remote control terminal network; the sieve plate 4 is welded by a plurality of transverse ribs (set on the left and right) and a plurality of longitudinal ribs (set on the front and back), and the specific number of the transverse ribs and the longitudinal ribs can be selected by the staff to adjust the size of the sieve holes on the sieve plate 4; the two electric rotating shafts 6 are placed on the left and right, and the two electric rotating shafts 6 are connected to the remote control terminal network; initially, the two pressing plates 7 are placed vertically, and the electric The connection position between the rotating shaft 6 and the adjacent pressing plate 7 is located on the opposite side of the two pressing plates 7. At the same time, the connection position between the electric rotating shaft 6 and the adjacent pressing plate 7 is not at the lowest side of the adjacent pressing plate 7. When the pressing plate 7 is initially, the sum of the areas of the opposite sides of the two pressing plates 7 is equal to the flow area of ​​the feed shell 3, which is used to ensure that the two pressing plates 7 can completely cover the sieve plate 4 after rotating to a horizontal state to avoid missing parts on the sieve plate 4; the electric push rod 8 is connected to the remote control terminal network, and the electric push rod 8 and the connecting plate 9 are both located on the left side of the guide shell 5; in this embodiment, the telescopic end of the electric push rod 8 is fixedly connected to the connecting plate 9.

[0025] Further, such as Figure 2 As shown, the guide shell 5 is in a "convex" shape as a whole, and the flow area on the feed side of the guide shell 5 is smaller than the flow area on the discharge side thereof, and the flow area on the discharge side of the guide shell 5 is equal to the flow area of ​​the feed shell 3, which is used to guide the material to the middle part of the screen plate 4 so that the material can move smoothly into the feed shell 3.

[0026] The specific working process of the above scheme is as follows: when it is necessary to use this device to prepare fluidized solidified soil, the remote control terminal starts the mixing module, and the staff uses the existing transportation device (generally an excavator) to transport the raw materials (including soil and solid waste, etc.) and additives (including curing agents, etc.) to the guide shell 5, and move downward along the guide shell 5 to the sieve plate 4, and then the raw materials and additives pass through the sieve plate 4 to move into the feed shell 3, and finally move into the shell of the mixing tank 2. At the same time, the existing pumping system is used to transport a certain amount of water into the mixing tank 2, so that the raw materials, additives and water in the mixing tank 2 gradually form mud (i.e., fluidized solidified soil) under the stirring action of the mixing module. After the mud preparation is completed, the staff releases the prepared mud through the slurry discharge port on the lower side of the mixing tank 2 for use.

[0027] In the above process, when a quantitative raw material is transported into the guide shell 5 by using a transport device, if the viscosity of the soil is high, its fluidity will be significantly reduced, making it difficult for the soil to smoothly pass through the sieve holes on the sieve plate 4 and enter the feed shell 3, resulting in accumulation on the sieve plate 4, affecting the feed speed and production efficiency of the entire system. In view of this situation, the following measures are taken to solve it: The remote control terminal starts the two electric shafts 6 at the same time, and the two electric shafts 6 respectively drive the adjacent pressure plates 7 to rotate, and then after the two pressure plates 7 are synchronously rotated from a vertical state to a horizontal state, the remote control terminal shuts down the two electric shafts 6 and starts the electric push rod 8 at the same time, and the telescopic end of the electric push rod 8 drives the connecting plate 9 to move downward synchronously, and the connecting plate 9 drives the two pressure plates 7 to move downward synchronously through the transmission of the two electric shafts 6, squeezing the soil accumulated on the sieve plate 4, so that the soil accumulated on the sieve plate 4 falls smoothly into the feed shell 3, ensuring the accuracy of the proportion, and no additional operation of the staff is required, making the entire workflow faster and ensuring the smooth progress of subsequent processes.

[0028] After using the device to produce a sufficient amount of fluidized solidified soil, the staff shuts down the mixing module and cleans the fluidized solidified soil and soil remaining on the device in preparation for subsequent use.

[0029] Embodiment 3: Based on embodiment 2, Figure 2-Figure 4 As shown, it also includes: a fixed column 10, which is fixedly connected to the telescopic end of the electric push rod 8, and a liquid storage portion is provided at the end of the fixed column 10 away from the electric push rod 8, and the connecting plate 9 is provided with a through hole, and the fixed column 10 is located in the through hole of the connecting plate 9; a push plate 11, which is slidably connected to the liquid storage portion of the fixed column 10; a limit block 12, which is slidably connected to the liquid storage portion of the fixed column 10, and the limit block 12 is used to connect the fixed column 10 and the connecting plate 9, and an elastic member 13 is fixedly connected between the limit block 12 and the push plate 11; an adjusting component, which is arranged on the connecting plate 9, and the adjusting component is used to change the position of the push plate 11.

[0030] In the above scheme, the fixed column 10 is located at the lower side of the telescopic end of the electric push rod 8, and the liquid storage part on the fixed column 10 is located at the lower side thereof. The specific number of push plates 11 can be specifically selected by the staff during actual use. At the same time, the specific shape of the liquid storage part of the fixed column 10 also changes synchronously with the specific number of push plates 11. If there is one push plate 11, the liquid storage part of the fixed column 10 is a blind hole; if there are two push plates 11, the liquid storage part of the fixed column 10 is a through hole. The figure and the text are both represented by taking two push plates 11 as an example, and the two push plates 11 are symmetrically distributed front and back; there are also two limit blocks 12, and the two limit blocks 12 are respectively located on the opposite sides of the two push plates 11; there are also two elastic members 13, and the elastic member 13 is a spring; two hemispherical grooves are arranged in the through hole of the connecting plate 9, and the two limit blocks 12 are respectively located in adjacent hemispherical grooves on the connecting plate 9.

[0031] The working process of the above scheme is as follows: when the telescopic end of the above-mentioned electric push rod 8 moves downward, the telescopic end of the electric push rod 8 drives the two limit blocks 12 to move downward synchronously through the fixed column 10, and then drives the connecting plate 9 to move downward synchronously through the two limit blocks 12, so as to achieve the above-mentioned purpose of squeezing the soil on the screen plate 4.

[0032] The two limit blocks 12 are gradually squeezed by the connecting plate 9 in the process of moving upward, so that the two limit blocks 12 are close to each other, and the two elastic members 13 are compressed and stored, until the two limit blocks 12 lose contact with the connecting plate 9, the connecting plate 9 and the fixed column 10 lose connection synchronously, and the fixed column 10 can no longer drive the connecting plate 9 to move downward, so as to avoid the two pressing plates 7 continuing to move downward after the two pressing plates 7 come into contact with the stones, causing the two pressing plates 7 and the sieve plate 4 to be deformed under pressure, thereby affecting the normal use of the two pressing plates 7 and the sieve plate 4.

[0033] After the connection between the connecting plate 9 and the fixing column 10 is lost, the remote control terminal starts the electric push rod 8 in reverse, so that the telescopic end of the electric push rod 8 drives the fixing column 10 to move upward, and the fixing column 10 drives the connecting plate 9 to move upward synchronously through the two limit blocks 12 (at this time, the two limit blocks 12 are both located on the lower side of the connecting plate 9). When the connecting plate 9 moves upward to the limit position (initial position), the fixing column 10 does not move upward to the initial position. Subsequently, when the fixing column 10 continues to move upward, the lower side of the connecting plate 9 squeezes the two limit blocks 12, so that the two limit blocks 12 approach each other again until the two limit blocks 12 are close to each other. The blocks 12 are all moved into the liquid storage part of the fixed column 10. During the upward movement of the fixed column 10, the two limit blocks 12 no longer approach each other. When the center of the two limit blocks 12 moves upward to the same horizontal line as the center of the hemispherical groove adjacent to the connecting plate 9, the two elastic members 13 respectively drive the adjacent limit blocks 12 to reset, so that the two limit blocks 12 are moved back to the adjacent hemispherical grooves on the connecting plate 9, and the connecting plate 9 is reconnected with the fixed column 10. Then the remote control terminal resets the two pressure plates 7 to the vertical position, and the staff cleans the remaining stones on the sieve plate 4 to ensure the smooth progress of the subsequent processes.

[0034] Further, such as Figure 3 and Figure 4 As shown, the adjustment component includes: a liquid storage shell 14, which is fixed to the connecting plate 9, and the liquid storage shell 14 is connected to the liquid storage part on the fixed column 10 through a hose; a movable plate 15, which is slidably connected to the liquid storage shell 14; a movable rod 16, which is rotatably connected to the movable plate 15, and the movable rod 16 is provided with an external thread, and the movable rod 16 passes through the liquid storage shell 14 and is threadedly connected thereto.

[0035] In the above scheme, the connecting position between the fixed column 10 and the hose thereon is located between the two push plates 11, and hydraulic oil is stored between the two push plates 11 and in the liquid storage shell 14, the moving rod 16 is located on the upper side of the moving plate 15, and the connecting position between the liquid storage shell 14 and the hose thereon is located below the moving plate 15.

[0036] When the soil is relatively dry, if the soil contains larger lumps of soil, the lumps of soil will still be intercepted by the sieve plate 4 and cannot move downward when they come into contact with the sieve plate 4. At the same time, when the two pressing plates 7 come into contact with the dry lumps of soil, they will also be intercepted by the dry lumps of soil and cannot move downward. The force required to break the dry lumps of soil is greater than that of the wet lumps of soil. Therefore, it is necessary to adjust the force required for the connection plate 9 and the fixed column 10 to be separated and connected according to the dryness and wetness of the soil, so as to ensure that the dry lumps of soil can be crushed by the squeezing of the two pressing plates 7, and then pass through the sieve plate 4 into the feed shell 3, so as to ensure the accuracy of the fluidized solidified soil ratio. The specific operation process is as follows: by rotating the moving rod 16, the moving rod 16 drives the moving plate 15 to move downward synchronously during the rotation process, and squeezes the hydraulic oil in the liquid storage shell 14 into the liquid storage part of the fixed column 10, so as to make the two push plates 11 move away from each other, compress the two elastic members 13, and then increase the force required for the two limit blocks 12 to approach each other, that is, increase the force required for the connection plate 9 and the fixed column 10 to be separated and connected.

The feed shell 3 is provided with two groups of first chutes that are symmetrically distributed, and the number of first chutes in each group of the feed shell 3 is consistent with the number of first cleaning blocks 22.

The first cleaning blocks 22 are provided with symmetrically distributed inclined portions, and the inclined portions of the first cleaning blocks 22 are provided with symmetrically distributed inclined surfaces; the first arc-shaped racks 23 have two symmetrically distributed first cleaning shells 17, which are respectively fixed to one side of the adjacent first arc-shaped groove 18, the center of the circle where the first arc-shaped rack 23 is located coincides with the center of the circle where the adjacent first arc-shaped groove 18 is located, and the first connecting rod 21 is fixed with a first gear meshing with the adjacent first arc-shaped rack 23; a cleaning assembly is provided on the fixed frame 1, and the cleaning assembly is used to assist the cleaning mechanism in cleaning impurities attached to the screen plate 4.

[0039] Further, such as Figure 5 , Figure 6 and Figure 8-Figure 10As shown, the cleaning assembly includes: a second cleaning shell 24, which has two symmetrically distributed ones, both of which are fixed to the upper side of the fixed frame 1, the two second cleaning shells 24 are fixed to the feed shell 3, and the two second cleaning shells 24 are respectively located on both sides of the feed shell 3, the two second cleaning shells 24 and the two first cleaning shells 17 are staggered, and one side of the two second cleaning shells 24 is provided with a second arc groove 25; a second threaded rod 26, a connecting column is fixed to the upper side of the fixed frame 1, and the second threaded rod 26 is rotatably connected to the connecting column of the fixed frame 1; a limiting rod 27 is fixed to the connecting column of the fixed frame 1; a second connecting rod 28 is slidably connected to the limiting rod 27, and the second threaded rod 26 is threadedly connected to the second connecting rod 28; a second elastic telescopic rod 29 is fixed to the side of the second connecting rod 28 away from the second threaded rod 26; a third connecting rod 30 is rotatably connected to the telescopic end of the second elastic telescopic rod 29, and the third connecting rod 30 Sliding in the adjacent second arc groove 25, a second torsion spring is arranged between the telescopic end of the second elastic telescopic rod 29 and the third connecting rod 30; the second cleaning blocks 31, which have a plurality of them, are all fixedly connected to the third connecting rod 30, the feed shell 3 is provided with two groups of second slide grooves symmetrically distributed, and the number of the second slide grooves in each group of the feed shell 3 is consistent with the number of the second cleaning blocks 31, the second cleaning blocks 31 slide along the adjacent second slide grooves on the feed shell 3, the second cleaning blocks 31 are provided with symmetrically distributed inclined portions, and the inclined portions of the second cleaning blocks 31 are provided with symmetrically distributed inclined surfaces; the second arc-shaped racks 32, which have two symmetrically distributed ones, are respectively fixedly connected to one side of the adjacent second cleaning shell 24 close to the adjacent second arc groove 25, the center of the circle where the second arc-shaped rack 32 is located is the same as the center of the circle where the adjacent second arc groove 25 is located, and the third connecting rod 30 is fixedly connected with a second gear meshing with the adjacent second arc-shaped rack 32.

[0040] In the above scheme, the two second cleaning shells 24 are symmetrically distributed front to back; the second arc-shaped groove 25 is located on the right side of the adjacent second cleaning shell 24, and the two second arc-shaped grooves 25 are symmetrically distributed front to back; the specific number of connecting columns on the fixing frame 1 can be specifically selected by the staff, and two are shown as an example in the figure, and the connecting column on the fixing frame 1 is located on its right side; a power module for driving the second threaded rod 26 to rotate is provided on the fixing frame 1, and the power module is an existing device and is not shown in the figure; the second elastic telescopic rod 29 is located on the left side of the second connecting rod 28, and the second threaded rod 26 rotates during the process The second elastic telescopic rod 29 is driven to move forward and backward through the transmission of the second connecting rod 28; the specific number of each group of second chutes on the feed shell 3 and the specific number of second cleaning blocks 31 are the same as the specific number of longitudinal ribs on the sieve plate 4; the two groups of second chutes on the feed shell 3 are respectively located on the front and rear sides thereof; the second arc-shaped rack 32 is located on the right side of the adjacent second cleaning shell 24, and the two second arc-shaped racks 32 are symmetrically distributed front and back, which are used to drive the third connecting rod 30 to rotate, and then drive all the second cleaning blocks 31 to change from a horizontal position to a vertical position, thereby increasing the falling speed of impurities in the second cleaning blocks 31.

[0041] Further, such as Figure 8 As shown, the angles between the inclined portions of the first cleaning block 22 and the second cleaning block 31 and the horizontal plane are both less than 45°, which is used to increase the separation speed between the sieve plate 4 and flexible impurities such as plastic bags.

[0042] Further, such as Figure 8 As shown, a first groove is provided on the transverse rib plate of the sieve plate 4, and a second groove is provided on the longitudinal rib plate of the sieve plate 4. The first groove on the sieve plate 4 and the second groove on the sieve plate 4 are vertically staggered and connected to each other, and the first groove on the sieve plate 4 is connected to the adjacent first slide groove on the feed shell 3, and the second groove on the sieve plate 4 is connected to the adjacent second slide groove on the feed shell 3. The first cleaning block 22 moves along the adjacent first groove on the sieve plate 4, and the second cleaning block 31 moves along the adjacent second groove on the sieve plate 4, which is used to clean out the soil accumulated in the first groove and the second groove, and at the same time to clean the flexible impurities attached to the sieve plate 4.

[0043] The specific working process of the above scheme is as follows: after the above-mentioned pressing plate 7 is reset upward to the initial position, the remote control terminal first starts the driving module, and the driving module drives the first threaded rod 19 to rotate, and the first threaded rod 19 drives the first elastic telescopic rod 20 to move to the right, and the telescopic end of the first elastic telescopic rod 20 drives all the first cleaning blocks 22 to move to the right synchronously through the transmission of the first connecting rod 21, and in the process of the first cleaning block 22 moving to the right, the first cleaning block 22 moves along the adjacent first groove on the sieve plate 4, and the inclined part on the right side of the first cleaning block 22 cleans the soil remaining in the adjacent first groove on the sieve plate 4, and at the same time drives the plastic on the adjacent transverse rib plate attached to the sieve plate 4 to move to the right. Soft impurities such as material bags move upward, so that such impurities are separated from the sieve plate 4 and move to the right synchronously with the adjacent first cleaning block 22, reducing the probability of such impurities falling into the mixing tank 2, thereby reducing the probability of such impurities being entangled on the mixing module in the mixing tank 2, ensuring the normal use of the mixing module, and reducing the influence of such impurities on the formation of the internal structure of the fluidized solidified soil (when soft impurities such as plastic bags are mixed into the fluidized solidified soil, the density of the fluidized solidified soil will change, thereby causing the uniformity and continuity of the material to decrease, and reducing the compressive strength and other mechanical properties of the fluidized solidified soil after solidification), ensuring the overall strength and stability of the prepared fluidized solidified soil.

[0044] Until the first connecting rod 21 moves to the right and contacts with the first arc-shaped groove 18 on the right side, the gear on the first connecting rod 21 moves synchronously to the position meshing with the arc-shaped rack on the first cleaning shell 17 on the right side. At this time, the first cleaning block 22 has been separated from the screen plate 4, and the soft impurities attached to the first cleaning block 22 gradually move downward along the inclined portion on the right side of the first cleaning block 22, thereby falling into the first cleaning shell 17 on the right side. In the process where the first connecting rod 21 continues to move to the right, the first connecting rod 21 moves downward along the first arc-shaped groove 18 on the right side and pulls out the telescopic end of the first elastic telescopic rod 20, so that the first elastic telescopic rod 20 accumulates force. In this process, the first gear on the first connecting rod 21 drives the first connecting rod 21 and other parts connected thereto to rotate synchronously (clockwise) under the action of the first arc-shaped rack 23 on the right side, and rotates the first cleaning block 22 from the horizontal direction to the vertical direction, thereby accelerating the falling speed of impurities accumulated on the first cleaning block 22.

[0045] Until the first elastic telescopic rod 20 moves to the right to the limit position, the first connecting rod 21 moves to the limit position synchronously, and then the remote control terminal reversely starts the driving module, and the control module drives the first threaded rod 19 to rotate in the opposite direction, thereby resetting the first elastic telescopic rod 20 to the left. After the first elastic telescopic rod 20 is reset to the left to the initial position, the remote control terminal shuts down the driving module and starts the power module at the same time, and the power module drives the second connecting rod 28 to move backward synchronously, thereby driving all the second cleaning blocks 31 to move backward synchronously, so as to remove impurities attached to the longitudinal ribs of the sieve plate 4 and the second cleaning blocks 31 on the sieve plate 4. The residual soil in the groove is cleaned out (the specific process will not be described in detail, just refer to the above). After the cleaning is completed, the remote control terminal starts the power module in reverse, and the power module drives the second connecting rod 28 to reset forward, and then drives all the second cleaning blocks 31 to reset forward to the initial position synchronously. The remote control terminal shuts down the power module, and the staff continues to transport raw materials and additives into the mixing tank 2 according to the above operations. In the subsequent use process, if the sieve plate 4 needs to be cleaned again, the remote control terminal moves the first cleaning block 22 and the second cleaning block 31 according to the above operations to clean the sieve plate 4.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
