Description

Technical Field

[0001] This invention relates to the field of soil cementitious agent production technology, specifically to a mixing device for producing soil cementitious agents. Background Technology

[0002] Soil cementitious solidifiers, as core materials for improving soft soil and poor foundation conditions, are widely used in municipal roads, high-speed railway subgrades, and land reclamation projects. Their core function is to enhance the compressive strength, impermeability, and stability of soil through the synergistic effect of multiple components such as cement, slag powder, lime, and alkali activators, thereby reducing the risk of engineering settlement. With increasing demands for soil solidification efficiency and environmental friendliness in infrastructure construction, mixing equipment has become the core equipment in their production process.

[0003] Soil cementitious solidifiers have complex raw material components, including not only dry powders such as cement and slag powder, but also heavy slag powder tends to settle at the bottom and light activator floats to the top in traditional mixing equipment, resulting in uneven mixing of the solidifier. Furthermore, the material in the middle of the tank is prone to forming a static area due to centrifugal force balance, causing cement, activator and other components to accumulate there. Summary of the Invention

[0004] To solve the above technical problems, the present invention is achieved through the following technical solution: a mixing device for producing soil cementitious solidifying agent, comprising a shell and a support column fixedly installed at the bottom of the shell, the support column being evenly distributed at the bottom of the shell, and a discharge pipe being fixedly connected to the middle of the bottom of the shell, the discharge pipe being connected to the shell. A connecting component is fixedly installed on the top of the housing. A feed pipe is fixedly connected to the outside of the connecting component, and a motor is fixedly connected to the middle of the top of the connecting component. The mixing component is installed inside the housing and is fixedly connected to the output end of the motor. The mixing component includes a rotating shaft, which is fixedly connected to the output end of a motor. Material is fed into the interior of the shell through a feed pipe. The motor, powered by an external power source, drives the rotating shaft to rotate. This rotation, via a central block, drives the mixing plate and spiral plate to rotate. The arc-shaped surface of the mixing plate conforms to the inclined edge of the limiting ring inside the tank. The gaps between the spiral plates form a shearing zone, breaking down and grinding slightly agglomerated material, further improving dispersibility. Simultaneously, because the dry powder material is fine-grained and easily adheres to the wall surface, forming a difficult-to-clean wall-hanging layer, the mixing plate conforms to the inner wall of the shell to prevent material from remaining there. This design can reduce material waste and prevent long-term accumulation and deterioration of residual materials, thus avoiding cross-contamination of the next batch of mixed materials and ensuring the consistency and purity of product composition. Two intermediate blocks are fixedly connected to the outer side of the rotating shaft, symmetrically positioned at both ends of the shaft in the vertical direction. Stirring plates are fixedly connected to the outer side of the intermediate blocks. The stirring plates are U-shaped, with each end fixedly connected to one of the two intermediate blocks. There are three stirring plates in total. A spiral plate is fixedly connected to the bottom of the inner wall of the stirring plate near the rotating shaft. The end of the spiral plate away from the stirring plate is fixedly connected to the top of the inner wall of the adjacent stirring plate.

[0005] Preferably, there are three spiral plates, evenly distributed around the rotating shaft. The spiral plates and stirring plates are alternately arranged. A trapezoidal block is fixedly connected to the center of each stirring plate. As the rotating shaft rotates, the stirring plate rotates. The trapezoidal block, recessed towards the rotating shaft, creates a localized negative pressure zone during stirring, causing the material to move into the tank. Furthermore, the central ring in the middle of the inner shell's inner wall blocks the circular flow of material as it rotates, forcibly diverting the material to the upper and lower sides of the ring. Simultaneously, the inclined design of the ring's edge guides the diverted material towards the stirring center, creating conditions for the stirring plate to grasp and disperse the material, increasing the material convection velocity. The guide plates above and below the trapezoidal block are inclined in opposite directions around the trapezoidal block as a symmetrical center. When the material enters the trapezoidal block, the upper guide plate throws the material upwards to the upper area of ​​the tank, while the lower guide plate... The square guide plate pushes the material downwards to the lower part of the tank, forming an upward and downward crisscrossing motion trajectory. Combined with the material diverted by the middle ring, it can achieve rapid exchange of materials in the upper, middle and lower parts of the tank, improving mixing efficiency. The opening of the trapezoidal block is located near the inner wall of the shell. The inner wall of the stirring plate is fixedly connected to the guide plate. There are multiple guide plates, with four guide plates forming a group. Each group of guide plates is fixedly connected to one stirring plate. The four guide plates in a group are evenly and symmetrically arranged around the trapezoidal block as the center. The guide plates at the upper and lower ends of the trapezoidal block are inclined in opposite directions. The guide plate at one end of the trapezoidal block is parallel to the axis of rotation. An inclined plate is set at the interval between two adjacent trapezoidal blocks. The two ends of the inclined plate are fixedly connected to the two adjacent trapezoidal blocks respectively. The inclined plate is parallel to the inclined side of the trapezoidal block.

[0006] Preferably, the shell includes a tank body, the bottom of which is fixedly connected to the discharge pipe. An inner shell is fixedly connected inside the tank body. A limit ring is fixedly connected to the bottom inner side of the tank body. The inner shell is located at the gap between the tank body and the limit ring, and its inner wall contacts the limit ring. The tank body and the inner shell form a double-shell structure. In this case, a sealed air gap is formed between the inner shell and the tank body, which can reduce the transfer of external low or high temperatures into the tank. When the equipment is in a cold environment, compared to a single-shell tank, it can effectively increase the temperature inside the tank, preventing the soil cementitious material from clumping or increasing in viscosity due to low temperatures. Simultaneously, by setting a fixed ring and a fixed block at the gap between the tank body and the inner shell as a connecting support structure for the double shell, and using a combination of grooves and protrusions in the fixed ring, the two are connected by a spring rather than rigid welding, which can reduce heat loss due to direct metal contact. The side of the limit ring furthest from the inner shell is... The tank is tilted and has two limiting rings symmetrically positioned at the top and bottom of the tank body. A fixing block is fixedly connected to the inner wall of the tank, with the fixing blocks vertically positioned and connected at both ends to the top and bottom of the tank body, respectively. Multiple fixing blocks are evenly distributed on the inner wall of the tank. A protrusion is fixedly connected to the side of the fixing block closest to the inner shell, with multiple protrusions evenly arranged on the fixing block. A fixing ring is fixedly connected to the outer side of the inner shell, with multiple fixing rings evenly arranged on the inner shell. An intermediate ring is fixedly connected to the middle of the inner wall of the inner shell, located inside a trapezoidal block. A slot is opened in the middle of the side of the fixing ring furthest from the inner shell, with a protrusion located inside the slot of the fixing ring. A spring is installed inside the slot of the fixing ring, with both ends of the spring fixedly connected to the protrusion and the slot of the fixing ring, respectively.

[0007] Preferably, the connecting assembly includes a connecting cylinder, which is fixedly connected to the feed pipe. The top center of the connecting cylinder is fixedly connected to the motor. A circular hole is formed on the side of the connecting cylinder away from the feed pipe. A positioning ring is fixedly connected inside the circular hole of the connecting cylinder. A central rod is provided inside the circular hole of the connecting cylinder. An annular groove is formed on the outer side of the central rod. The positioning ring is located inside the annular groove of the central rod. Initially, under the elastic force of the spring plate, the side of the annular groove near the spring plate is in close contact with the positioning ring. The inclined side of the positioning ring is parallel to the inclined side of the inner wall of the annular groove. When the equipment starts working, the air pressure inside the tank will gradually increase with the mixing and stirring time. When the internal air pressure exceeds a certain threshold, the spring plate is stretched under the action of the air pressure, causing the central rod to move towards the connecting cylinder inside the circular hole. The outer side of the cylinder moves, so that the positioning ring is located in the middle of the inner ring groove. At this time, the gas inside can be discharged through the gap between the positioning ring and the ring groove, avoiding weld cracking, shell deformation or even explosion of the tank due to overpressure. The risk of equipment damage is reduced, and the injury to operators caused by flying fragments and splashing materials is prevented. A slider is set inside the circular hole of the connecting cylinder, and a groove is opened on the outer side of the intermediate rod. The connecting cylinder is slidably connected to the groove on the intermediate rod through the slider. The intermediate rod passes through the connecting cylinder through the circular hole. A circular plate is fixedly connected to one end of the intermediate rod. The circular plate is located on the outer side of the connecting cylinder. A spring plate is fixedly connected to the outer side of the circular plate near the intermediate rod. The end of the spring plate away from the circular plate is fixedly connected to the connecting cylinder. There are multiple spring plates, which are evenly distributed on the circular plate.

[0008] This invention provides a mixing device for producing soil cementitious solidifying agents. It has the following beneficial effects: (i) The mixing equipment for producing this soil cementitious solidifying agent drives the mixing plate and spiral plate to rotate through the intermediate block via the rotating shaft. The arc-shaped surface of the mixing plate can fit the inclined edge of the limiting ring inside the tank. The gap between the spiral plates forms a gap shearing zone, which divides and grinds the slightly lumped material, further improving its dispersibility.

[0009] (ii) The mixing equipment for producing this soil cementitious solidifying agent, through the trapezoidal blocks that are recessed inward towards the rotating shaft, will form a local negative pressure zone during the mixing and rotation, causing the material to move into the tank. In addition, the middle ring in the middle of the inner wall of the inner shell can block the circumferential flow of the material formed by the mixing and rotation, and force the material to be diverted to the upper and lower sides of the ring. At the same time, the inclined design of the ring edge guides the diverted material to converge towards the mixing center, creating conditions for the mixing plate to grasp and disperse, and improving the material convection speed.

[0010] (III) The mixing equipment for producing this soil cementitious solidifying agent uses guide plates above and below the trapezoidal block that are tilted in opposite directions with the trapezoidal block as the center of symmetry. When the material enters the trapezoidal block, the upper guide plate throws the material upward to the upper area of ​​the tank, and the lower guide plate pushes the material downward to the lower area of ​​the tank, forming an upward throwing and downward pushing cross motion trajectory. Combined with the material diverted by the middle ring, it can realize the rapid exchange of materials in the upper, middle and lower parts of the tank, and improve the mixing efficiency.

[0011] (iv) The mixing equipment for producing the soil cementitious solidifying agent uses a spring plate to stretch the middle rod inside the round hole towards the outside of the connecting cylinder, so that the positioning ring is located in the middle of the ring groove. At this time, the gas inside can be discharged through the gap between the positioning ring and the ring groove, avoiding weld cracking, shell deformation or even explosion of the tank due to overpressure, reducing the risk of equipment damage, and preventing injury to operators from flying fragments and splashing materials.

Detailed Implementation

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] First embodiment, such as Figures 1 to 4 As shown, the present invention provides a technical solution: a mixing device for producing soil cementitious solidifying agent, comprising: a shell 2, and a support column 1 fixedly installed at the bottom of the shell 2, the support column 1 being multiple in number and evenly distributed at the bottom of the shell 2, and a discharge pipe 5 fixedly connected to the middle of the bottom of the shell 2, the discharge pipe 5 being connected to the shell 2. Connecting component 3 is fixedly installed on the top of housing 2. A feed pipe 4 is fixedly connected to the outside of connecting component 3. A motor 7 is fixedly connected to the middle of the top of connecting component 3. The mixing component 6 is installed inside the housing 2 and is fixedly connected to the output end of the motor 7; The mixing component 6 includes a rotating shaft 61, which is fixedly connected to the output end of a motor 7. Material is fed into the interior of the shell 2 through the feed pipe 4. The motor 7, powered by an external power source, drives the rotating shaft 61 to rotate. This rotation, via the intermediate block 62, causes the stirring plate 64 and the spiral plate 63 to rotate. The arc-shaped surface of the stirring plate 64 fits against the inclined edge of the limiting ring 25 inside the tank 21. The gaps between the spiral plates 63 form a shearing zone, dividing and grinding slightly agglomerated material, further improving dispersibility. Simultaneously, because the dry powder material is fine and easily adheres to the wall surface, forming a difficult-to-clean wall layer, the stirring plate 64 fits against the inner wall of the inner shell 23 to prevent material from remaining on the inner wall of the inner shell 23. This can reduce material waste and prevent long-term accumulation and deterioration of residual materials from causing cross-contamination of the next batch of mixed materials, thus ensuring the consistency and purity of product composition. There are two intermediate blocks 62 fixedly connected to the outer side of the rotating shaft 61. The two intermediate blocks 62 are symmetrically arranged at both ends of the vertical direction of the rotating shaft 61. A stirring plate 64 is fixedly connected to the outer side of the intermediate block 62. The stirring plate 64 is U-shaped. The two ends of the stirring plate 64 are fixedly connected to the two intermediate blocks 62 respectively. There are three stirring plates 64. A spiral plate 63 is fixedly connected to the bottom of the inner wall of the stirring plate 64 near the rotating shaft 61. The end of the spiral plate 63 away from the stirring plate 64 is fixedly connected to the top of the inner wall of the adjacent stirring plate 64.

[0016] There are three spiral plates 63, evenly distributed around the rotating shaft 61. The spiral plates 63 and stirring plates 64 are alternately arranged. A trapezoidal block 66 is fixedly connected to the middle of the stirring plate 64. The rotation of the rotating shaft 61 drives the stirring plate 64 to rotate. At this time, the trapezoidal block 66, which is concave towards the rotating shaft 61, creates a local negative pressure zone during stirring and rotation, causing the material to move into the tank. Furthermore, the intermediate ring 26 in the middle of the inner wall of the inner shell 23 can block the circumferential flow of material formed by the stirring and rotation, forcibly diverting the material to the upper and lower sides of the ring. Simultaneously, the inclined design of the ring edge guides the diverted material to converge towards the stirring center, creating conditions for the stirring plate 64 to grasp and disperse the material, increasing the material convection velocity. The guide plates 67 above and below the trapezoidal block 66 are inclined in opposite directions with the trapezoidal block 66 as the center of symmetry. When the material enters the trapezoidal block 66, the upper guide plate throws the material upwards to the upper area of ​​the tank 21, and the lower guide plate... The material is pushed downwards to the lower part of the tank 21, forming an upward and downward intersecting motion trajectory. Combined with the material diverted by the intermediate ring, it can achieve rapid exchange of materials in the upper, middle and lower parts of the tank, improving mixing efficiency. The opening of the trapezoidal block 66 is located near the inner wall of the shell 2. The inner wall of the stirring plate 64 is fixedly connected to a guide plate 67. There are multiple guide plates 67. Four guide plates 67 are grouped together. The guide plates 67 in a group are fixedly connected to one stirring plate 64. The four guide plates 67 in a group are evenly and symmetrically arranged around the trapezoidal block 66. The guide plates 67 at the upper and lower ends of the trapezoidal block 66 have opposite inclination directions. The guide plate 67 at one end of the trapezoidal block 66 is parallel. The guide plate 67 is perpendicular to the rotating shaft 61. An inclined plate 65 is provided at the interval between two adjacent trapezoidal blocks 66. The two ends of the inclined plate 65 are fixedly connected to the two adjacent trapezoidal blocks 66 respectively. The inclined plate 65 is parallel to the inclined side of the trapezoidal block 66.

[0017] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 5 to 6As shown, the shell 2 includes a tank body 21, the bottom of which is fixedly connected to the discharge pipe 5. An inner shell 23 is fixedly connected inside the tank body 21. A limiting ring 25 is fixedly connected to the bottom inner side of the tank body 21. The inner shell 23 is located at the gap between the tank body 21 and the limiting ring 25, and its inner wall contacts the limiting ring 25. The tank body 21 and the inner shell 23 form a double-shell structure. At this time, a sealed air gap is formed between the inner shell 23 and the tank body 21, which can reduce the transfer of external low or high temperatures into the tank. When the equipment is in a cold environment... In this environment, compared to a single-shell tank, it can effectively increase the internal temperature of the tank, preventing the soil cementitious material from clumping or increasing in viscosity due to low temperature. Simultaneously, by setting a fixing ring 24 and a fixing block 22 at the interval between the tank body 21 and the inner shell 23 as a connecting support structure for the double shell, and employing a combination of the groove and protrusion 27 of the fixing ring 24, the two are connected by a spring rather than rigid welding, which reduces heat loss due to direct metal contact. The side of the limiting ring 25 away from the inner shell 23 is inclined. There are two limiting rings 25, symmetrically arranged at the top and bottom inside the tank body 21. A fixing block 22 is fixedly connected to the inner wall of the tank body 21. The fixing block 22 is vertically arranged, with its two ends connected to the top and bottom of the tank body 21, respectively. There are multiple fixing blocks 22, evenly distributed on the inner wall of the tank body 21. A protrusion 27 is fixedly connected to the side of the fixing block 22 closest to the inner shell 23. There are multiple protrusions 27, evenly arranged on the fixing block 22. A fixing ring 24 is fixedly connected to the outer side of the housing 23. There are multiple fixing rings 24, which are evenly arranged on the inner housing 23. An intermediate ring 26 is fixedly connected to the middle of the inner wall of the inner housing 23. The intermediate ring 26 is located inside the trapezoidal block 66. A slot is opened in the middle of the side of the fixing ring 24 away from the inner housing 23. A protrusion 27 is located inside the slot of the fixing ring 24. A spring 28 is provided inside the slot of the fixing ring 24. The two ends of the spring 28 are fixedly connected to the protrusion 27 and the slot of the fixing ring 24, respectively.

[0018] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 7 to 8As shown, the connecting assembly 3 includes a connecting cylinder 31, which is fixedly connected to the feed pipe 4. The top center of the connecting cylinder 31 is fixedly connected to the motor 7. A circular hole is opened on the side of the connecting cylinder 31 away from the feed pipe 4. A positioning ring 32 is fixedly connected inside the circular hole of the connecting cylinder 31. An intermediate rod 33 is set inside the circular hole of the connecting cylinder 31. An annular groove 34 is opened on the outer side of the intermediate rod 33. The positioning ring 32 is located inside the annular groove 34 of the intermediate rod 33. In the initial state, under the elastic force of the spring plate 36, the side of the annular groove 34 near the spring plate 36 is in close contact with the positioning ring 32. The inclined side of the positioning ring 32 is parallel to the inclined side of the inner wall of the annular groove 34. When the equipment starts to work, the air pressure inside the tank 21 will slowly increase with the mixing and stirring time. When the internal air pressure exceeds a certain threshold, the spring plate 36 is stretched under the action of air pressure, so that the intermediate rod 33 is inside the circular hole towards the connecting cylinder 31. The outward movement causes the positioning ring 32 to be located in the middle of the annular groove 34. At this time, the internal gas can be discharged through the gap between the positioning ring 32 and the annular groove 34, preventing the tank 21 from cracking due to overpressure, deforming of the shell, or even exploding. This reduces the risk of equipment damage and also prevents injury to operators from flying fragments and splashing materials. A slider is provided inside the circular hole of the connecting cylinder 31, and a groove 35 is provided on the outer side of the intermediate rod 33. The connecting cylinder 31 is slidably connected to the groove 35 on the intermediate rod 33 through the slider. The intermediate rod 33 passes through the connecting cylinder 31 through the circular hole. A circular plate 37 is fixedly connected to one end of the intermediate rod 33. The circular plate 37 is located on the outer side of the connecting cylinder 31. A spring plate 36 is fixedly connected to the outer side of the circular plate 37 near the intermediate rod 33. The end of the spring plate 36 away from the circular plate 37 is fixedly connected to the connecting cylinder 31. There are multiple spring plates 36, which are evenly distributed on the circular plate 37.

[0019] In use, the material is added into the interior of the shell 2 through the feed pipe 4. The motor 7 is connected to an external power source and drives the rotating shaft 61 to rotate. The rotating shaft 61 drives the stirring plate 64 and the spiral plate 63 to rotate through the intermediate block 62. The arc-shaped surface of the stirring plate 64 can fit the inclined edge of the limiting ring 25 inside the tank 21. The gap between the spiral plates 63 forms a gap shearing zone, which divides and grinds the slightly agglomerated material, further improving the dispersibility.

[0020] The rotation of the shaft 61 drives the stirring plate 64 to rotate. At this time, the trapezoidal block 66, which is recessed inward towards the shaft 61, will form a local negative pressure zone during the stirring and rotation, causing the material to move into the tank. The middle ring 26 in the middle of the inner wall of the inner shell 23 can block the circumferential flow of the material formed by the stirring and rotation, and force the material to be diverted to the upper and lower sides of the ring. At the same time, the inclined design of the edge of the ring guides the diverted material to converge towards the stirring center, creating conditions for the stirring plate 64 to grasp and disperse, and increasing the material convection speed. The guide plates 67 above and below the trapezoidal block 66 are inclined in opposite directions with the trapezoidal block 66 as the center of symmetry. When the material enters the trapezoidal block 66, the upper guide plate throws the material upward to the upper area of ​​the tank 21, and the lower guide plate pushes the material downward to the lower area of ​​the tank 21, forming an upward throwing and downward pushing cross motion trajectory. With the material diverted by the middle ring, the material in the upper, middle and lower parts of the tank can be rapidly exchanged, improving the mixing efficiency.
