Description

Technical Field

[0001] The present invention belongs to LC 3 The technical field of low-carbon gelling materials is particularly related to a method for producing LC 3 A device for preparing low-carbon cementitious materials. Background Art

[0002] LC 3 Low-carbon cementitious material is a new type of low-carbon cementitious material designed to replace traditional cement. This material can significantly reduce carbon dioxide emissions during the production process, which is of great significance to environmental protection and sustainable development. 3 Low carbon cementitious materials are prepared by combining two raw materials, lime and calcined clay, to form a new, environmentally friendly cement substitute that has great potential. 3 In the process of low-carbon cementitious materials, it is necessary to mix the crushed lime and calcined clay through mixing equipment. Specifically, lime and calcined clay enter the space in the mixing device through different conveying pipes, so that a lime area and a calcined clay area are formed in the space, making it difficult to mix and stir the lime and calcined clay more fully through the mixing and stirring facilities in the space in the mixing device, reducing the uniformity of the lime and calcined clay, and thus affecting the quality of the final product. Among them, it is often difficult to achieve a sufficient mixing effect when only lime and calcined clay are mixed through a mixing device, which is mainly due to the following two reasons:

[0003] 1. Lime and calcined clay have significant differences in physical properties, such as particle size, density and fluidity, which may lead to their uneven distribution in the mixing device. Specifically, lime is usually loose, while calcined clay may show higher viscosity. This difference in physical properties may cause them to form different areas in the mixing device, thus affecting the uniformity of mixing.

[0004] 2. The stirring dynamics in the mixing device are crucial to achieve uniform mixing. If the design and configuration of the stirring rods cannot adapt to the different fluidity and reactivity of lime and calcined clay, inadequate mixing may result; improper setting of the gap between the stirring rods will also affect the mixing effect.

[0005] In summary, the reason why lime and calcined clay form different areas in the mixing device and are difficult to fully mix and stir is related to the difference in the physical properties of the two raw materials themselves and the adaptability of the mixing mechanics. Therefore, it is urgent to design a mixing device that can effectively break the local areas formed by lime and calcined clay and improve the problem of insufficient mixing to ensure sufficient and uniform mixing.

[0006] After searching, the existing Chinese invention application document with publication number CN118990799A discloses a processing device for producing solid waste cementitious materials for cement, "including a mixing tank, the top of the mixing tank is connected with a first feed pipe and a second feed pipe, the bottom is connected with a discharge pipe, the inside of the mixing tank is provided with a rotating shaft rotatably mounted along its axial direction, the outside of the rotating shaft is fixedly sleeved with a mixing disk at a position close to the top of the mixing tank, the outside of the rotating shaft is sleeved with a sleeve below the mixing disk, and a plurality of first stirring paddles are distributed on the sleeve, and the first feeding pipe and the second feeding pipe enter the mixing tank. The internal materials are premixed on the mixing disk, and then fall to the bottom of the mixing tank through the mixing disk flipping. During the flipping process, the mixing disk drives the sleeve to slide relative to the rotating shaft while rotating synchronously with the rotating shaft. "The device uses a mixing disk to solve the problem of large-area accumulation of solid waste materials and activators in the initial state when they are fed into the stirring device, thereby prolonging the stirring time. The solid waste materials and activators are fed into the stirring tank and then fall onto the rotating mixing disk, and the two materials are alternately spread out in a circular shape on the mixing disk to achieve premixing of the two materials, so as to save subsequent stirring time. However, the device is relatively simple in structure and functional details, and has the following limitations: First, the device does not take into account the physical properties of lime and calcined clay, and does not take into account the adjustment of the gap and configuration of the stirring rod, so that more sufficient mixing cannot be achieved; at the same time, the device does not take into account the possible blockage problem during the feeding process, and there is no corresponding structural design to prevent the blockage of the feed port, which has obvious shortcomings. Therefore, the device has certain limitations and is not suitable for LC 3 The mixing operation of lime and calcined clay in the preparation of low carbon cementitious materials.

The inner shell can be used to initially concentrate lime and burnt clay, and the rotating plate can be used to rotate to achieve initial mixing and stirring of the materials in the inner shell. At the same time, the device uses the guide block on the rotating plate to effectively guide the mixed raw materials at the corner of the inner shell to move out of the corner, which has unique advantages in terms of mixing uniformity of lime and burnt clay; and, the design of the rotating plate squeezing the touch block during rotation and driving the stirring frame to move up and down at the feed port can also effectively prevent the blockage of the first inlet and the second inlet, thereby significantly improving the feeding speed and preparation efficiency; in addition, the present application further provides a detachable horizontal stirring component and a vertical stirring component, so that the gap inside the device can be flexibly adjusted, which can adapt to the mixing and diversion requirements under different stirring amounts, and further enhance the applicability and flexibility of the equipment.

[0047] The top of the tank body 1 is connected to a first inlet 4 and a second inlet 5, and the first inlet 4 and the second inlet 5 are arranged opposite to each other; the bottom of the tank body 1 is connected to an outlet 7, and the outlet 7 is provided with an electromagnetic valve 6 for controlling the on and off of the outlet 7; the inside of the tank body 1 is provided with an inner shell 16, a transverse flow guide component, and a longitudinal flow guide component from top to bottom; in this embodiment, the tank body 1 is a cylindrical-conical combination structure, including a cylindrical area and a conical area, the inner shell 16 and the transverse flow guide component are located in the cylindrical area, and the longitudinal flow guide component is located in the conical area.

[0048] The inner shell 16 is annular and fixedly mounted on the upper inner wall of the tank body 1 . The top of the inner shell 16 is connected to the first inlet 4 and the second inlet 5 . A plurality of leakage holes are evenly formed at the bottom of the inner shell 16 , and a movable groove is formed on the inner end surface of the inner shell 16 .

[0049] There are two rotating plates 17, and the two rotating plates 17 are symmetrically fixed on the upper part of the stirring frame 3; specifically, the rotating plate 17 includes a connecting plate and a stirring plate, the connecting plate has a shape matching the cross-section of the movable groove, one end of the connecting plate is fixedly connected to the stirring frame 3, and the other end of the connecting plate is provided with the stirring plate, the stirring plate is located on the inner side of the inner shell 16, and has the same shape as the single-side cross-section of the inner shell 16, and is used for pre-mixing the lime and calcined clay inside the inner shell 16; two guide blocks 18 are symmetrically fixed on the stirring plate, and the two guide blocks 18 are respectively located on both sides of the lower end of the stirring plate, are wedge-shaped, and the tip of the wedge faces the center of the stirring plate, and is used to guide the mixed raw materials at the corner of the inner shell 16 to move out of the corner.

At a suitable rotation speed, the rotating plate 17 can make the raw materials form a vortex or laminar flow, reducing the possibility of raw materials flying. It also meets the requirements for the mixing degree of raw materials in the premixing stage. Even if a small amount of raw materials fly up, due to the continuous stirring of the rotating plate 17, the flying raw materials will soon be re-entered into the mixing area, and can be further mixed evenly in the subsequent overall stirring process in the tank body 1.

[0051] The transverse flow guide assembly is located in the middle of the inner wall of the tank body 1, the transverse stirring assembly is located in the middle of the stirring frame 3, and the transverse stirring assembly and the transverse flow guide assembly are staggered with each other; specifically, the transverse flow guide assembly includes two groups of shaft rods 9, the two groups of shaft rods 9 are relatively symmetrically fixed on the inner wall of the tank body 1, all the shaft rods 9 in each group are longitudinally distributed in a row and the inner end faces are flush, and there is a gap between the shaft rods 9 in the same group; at the same time, the transverse stirring assembly includes two groups of roller sleeves 8, the two groups of roller sleeves 8 are detachably installed on the middle outer wall of the stirring frame 3, and the length of each roller sleeve 8 is determined according to the inner diameter of the tank body 1, that is, the length of each roller sleeve 8 is slightly smaller than the distance from the inner wall of the tank body 1 to the outer wall of the stirring frame 3; and each group of roller sleeves 8 has a setting spacing matching the two groups of shaft rods 9, so that each roller sleeve 8 cooperates with each shaft rod 9 when rotating with the stirring frame 3 without interfering with each other.

[0052] The longitudinal flow guide assembly is located at the lower part of the inner wall of the tank body 1, the longitudinal stirring assembly is located at the lower part of the stirring frame 3, and the longitudinal stirring assembly and the longitudinal flow guide assembly are staggered with each other; specifically, the longitudinal flow guide assembly includes two groups of rotating sleeves, and the two groups of rotating sleeves are relatively symmetrically fixed to the inner side of the bottom wall of the tank body 1, and the rotating sleeves in each group are horizontally distributed in a row, and the upper end surfaces of each rotating sleeve are flush, and there is a gap between each rotating sleeve in the same group; at the same time, the longitudinal stirring assembly includes two bottom plates 10 and two groups of stirring sleeves The two groups of stirring sleeves are respectively arranged on the lower end surfaces of the two bottom plates 10, and the two bottom plates 10 are symmetrically fixed to the lower part of the stirring frame 3.

[0053] In this embodiment, the stirring sleeve includes a first stirring sleeve 11, a second stirring sleeve 12 and a third stirring sleeve 13 from the inside to the outside, and each set of rotating sleeves includes a first rotating sleeve 14 and a second rotating sleeve 15; the first rotating sleeve 14 has a diameter that matches the width of the gap between the first stirring sleeve 11 and the second stirring sleeve 12; the second rotating sleeve 15 has a diameter that matches the width of the gap between the second stirring sleeve 12 and the third stirring sleeve 13, so that the raw materials can be squeezed and crushed while mixing, increasing the contact between the raw materials, thereby improving the mixing uniformity. In another embodiment, each rolling sleeve 8 can be detachably fixed to the stirring frame 3, and each stirring sleeve can be detachably fixed to the bottom plate 10, so that when any rolling sleeve 8 or any stirring sleeve is damaged, it can be replaced in time to ensure the stable operation of the preparation device. At the same time, through detachable fixing, the diameter of the rolling sleeve 8 and the stirring sleeve can be adjusted according to the raw materials put in, avoiding the problem of uneven stirring caused by too large a gap, and avoiding the problem of increased stirring resistance and reduced efficiency caused by too small a gap.

[0054] The first inlet 4 and the second inlet 5 are each provided with an anti-blocking mechanism, the lower edge of which is lower than the upper edge of the rotating plate 17, so that the anti-blocking mechanism can reciprocate up and down in the corresponding inlet with the contact during the rotation of the rotating plate 17. The anti-blocking mechanism includes a transmission component, an elastic component, and a dredging component; during operation, when the rotating plate 17 rotates, when the rotating plate 17 touches the transmission component, the transmission component is subjected to upward pressure and transmits the force to the transmission component and the elastic component, and the elastic component is pressed upward by the force, so that the elastic component is forced to shrink upward, and drives the dredging component to move up and down in the first inlet 4 and the second inlet 5 respectively.

[0055] Specifically, the transmission assembly includes a trigger block 23 and a connecting bar 22 , and the connecting bar 22 is disposed at both ends of the trigger block 23 . The elastic component is arranged on the outer end of the connecting strip 22, and the elastic component includes a telescopic block 21, a spring 20 and a circular sleeve 19. The circular sleeve 19 passes through the inner shell 16 and the upper end surface of the tank body 1 and is fixed to the top of the tank body 1.

The dredging assembly includes a moving rod 24 and a stirring frame 25 . The moving rod 24 is located inside each corresponding inlet, and a plurality of stirring frames 25 are fixed on the moving rod 24 . The stirring frames 25 are evenly distributed along the radial height direction of the moving rod 24 .

[0056] During the rotation of the rotating plate 17, when the rotating plate 17 touches the touch block 23, the touch block 23 is subjected to upward pressure and transmits the force to the connecting strip 22. After the connecting strip 22 is subjected to the force, the force is transmitted to the telescopic block 21. After the telescopic block 21 is subjected to the force, it presses the spring 20 upward, so that the spring 20 is forced to contract. When the rotating plate 17 is separated from the touch block 23, the force disappears, and the spring 20 returns to its initial state. The elastic elasticity of the spring 20 can drive the moving rod 24 to move up and down in the corresponding inlet, so that the stirring frame 25 can be used to achieve the anti-blocking effect inside the corresponding inlet. At the same time, it can also improve the circulation efficiency of the raw materials at the inlet, ensure that the raw materials can smoothly enter the tank body 1, and improve the operation efficiency and reliability.

In a further preferred embodiment, the preparation unit further includes an external display, which is signal-connected to the control unit and displays the result of image processing by the control unit in real time.

At the same time, the staff controls the driving motor 2 to operate, so that the output end of the driving motor 2 rotates to drive the stirring frame 3 to rotate, so that the stirring frame 3 fully mixes and stirs the lime and calcined clay inside the tank body 1 to improve the uniformity of the mixing; including the following specific steps:

[0065] S3-1. Pre-mixing and stirring the lime and calcined clay by using the rotating plate 17 to complete the preliminary mixing of the lime and calcined clay, obtain a preliminary mixed raw material, improve the stability and uniformity of the entire system in the subsequent mixing process, and make the obtained preliminary mixed raw material fall into the middle and lower parts of the tank body 1 from the circular hole on the inner shell 16: Specifically, the stirring frame 3 drives the rotating plate 17 located on the upper part of the tank body 1 to rotate, so that the rotating plate 17 mixes and stirs the lime and calcined clay on the inner side of the inner shell 16, and the guide block 18 can guide the mixed raw material at the corner of the inner shell 16 to move out of the corner, and the pre-mixed preliminary mixed raw material moves out of the inner shell 16 through the circular hole and moves to the lower part of the tank body 1.

[0066] By mixing lime and calcined clay first, the temperature and humidity during the mixing process can be better controlled, making the reaction of lime and calcined clay more gentle, which is conducive to adjusting the reaction conditions within a wider range, helping to improve the stability and uniformity of the entire system in the subsequent mixing process, and to a certain extent, promoting the overall reaction activity when mixing with cement clinker and other additives later.

[0067] S3-2, the preliminary mixed raw materials are mixed and stirred for a second time by means of the transverse stirring assembly and the longitudinal stirring assembly to obtain the mixed raw materials: specifically, the stirring frame 3 drives all the roller sleeves 8 located in the middle of the stirring frame 3 to rotate, so that the roller sleeves 8 cooperate with the corresponding shaft rods 9 when passing through the shaft rods 9 provided on the inner wall of the tank body 1; at the same time, the stirring frame 3 drives the bottom plate 10 located at the lower part of the stirring frame 3 to rotate, and the rotation of the bottom plate 10 further drives all the corresponding stirring sleeves to rotate, so that the first stirring sleeve 11, the second stirring sleeve 12 and the third stirring sleeve 13 cooperate with the corresponding rotating sleeves when passing through the first rotating sleeve 14 and the second rotating sleeve 15 provided on the inner wall of the tank body 1. Through the mutual cooperation between the transverse stirring assembly and the transverse flow guide assembly, and the mutual cooperation between the longitudinal stirring assembly and the longitudinal flow guide assembly, through their respective relative activities, the preliminary mixed raw materials can be squeezed to increase the degree of crushing of the preliminary mixed raw materials, and at the same time, the gap between the stirring assembly and the corresponding flow guide assembly can be used to ensure the flow guide requirements during the mixing process.

[0068] S4. At the same time, during the rotation of the rotating plate 17, when the rotating plate 17 squeezes the touch block 23, the touch block 23 transmits the force to the telescopic block 21 through the connecting strip 22, so that the spring 20 is compressed and contracted, so that each touch block 23 drives the corresponding moving rod 24 to move upward inside the first inlet 4 and the second inlet 5; when the rotating plate 17 is separated from the touch block 23, the contracted spring 20 can use its own restoring force to drive the touch block 23 to reset through the telescopic block 21 and the connecting strip 22, so that each touch block 23 drives the corresponding moving rod 24 to move upward inside the corresponding first inlet 4 and the second inlet 5. By moving the moving rod 24 up and down inside the corresponding inlet, the multiple stirring racks 25 on the moving rod 24 can be driven to stir up and down inside the corresponding inlet, so as to effectively prevent the first inlet 4 and the second inlet 5 from being blocked during transportation, and improve the preparation efficiency by increasing the feeding speed.

[0069] S5. Keep stirring until the mixture is evenly mixed, and discharge from outlet 7 after the mixture is completely mixed.

[0070] In another embodiment, when the preparation device further includes a control unit, the following specific steps are also included:

[0071] S5-1. During the stirring process, the mixing condition in the tank body 1 is monitored in real time by the control unit and the sensor in the tank body 1. Specifically, the mixed raw materials are scanned by the optical sensor arranged in the tank body 1, and the obtained scanning result signal is transmitted to the control unit. The control unit processes and analyzes the scanning result signal by using image processing technology, generates a pseudo-color image and outputs the display to an external display. The mixed raw materials are judged whether they are completely mixed and uniform according to the display color. The uniformly mixed area is displayed in green, and the unevenly mixed area is displayed in red. Through the visual display method, the mixing state inside the tank body 1 can be judged in time, and it can be used as an analysis basis for the optimization of the production process and the replacement of the stirring component, so that the mixing effect under different raw materials, different ratios, and different total mixing amounts can be improved more targeted, and it has a wide range of applicability.

[0072] S5-2. When there is still a red area, that is, the tank body 1 is not mixed evenly, continue stirring until there is no red area, that is, the tank body 1 is completely mixed evenly, and then the control unit controls the electromagnetic valve 6 located at the outlet 7 of the tank body 1 to open, so that the mixed raw materials move to the subsequent preparation device through the outlet 7 and the external pipeline. When the mixed raw materials in the tank body 1 are completely discharged, stop stirring and close the electromagnetic valve 6.

[0073] In step S5-2, after the lime and calcined clay are completely mixed and before the electromagnetic valve 6 is opened, the lime used to produce LC can be transported to the calcined clay by an external conveying device. 3Other raw materials of low-carbon cementitious material are also transported into the inner side of the tank body 1 through the first inlet 4 and the second inlet 5, and continue to be stirred until they are completely mixed, so that all raw materials can be mixed in the same device, reducing the loss during the transfer process and the risk of ratio error.
