Description

Technical Field

[0001] The present invention relates to the technical field of building material production, and particularly to a solid-liquid batching device for autoclaved aerated concrete brick production. Background Art

[0002] In the field of autoclaved aerated concrete brick production, with the continuous increase in the demand for green, environmental-friendly and high-quality wall materials in the construction industry, the market share of autoclaved aerated concrete bricks has been continuously expanding due to their excellent properties such as light weight, heat insulation and sound insulation. Under this background, for the key link in the production process of autoclaved aerated concrete bricks, namely the solid-liquid batching link, its accuracy and efficiency have attracted more and more attention.

[0003] Currently, in the solid-liquid batching device for autoclaved aerated concrete brick production commonly seen on the market, in the solid-liquid batching and feeding link, most adopt a continuous feeding method. Continuous feeding relies on relatively fixed flow control devices. However, in actual production, factors such as the characteristics of the materials (such as uneven particle size distribution of solid materials and viscosity fluctuations of liquid materials) and the wear of the equipment itself will cause deviations in flow control. This deviation accumulates continuously during continuous production, making it difficult to accurately control the proportion of solid-liquid batching input into the mixing equipment each time. For example, in a large-scale automated production line, when the production task is large and the equipment runs for a long time, the inner wall of the solid material conveying pipeline may be worn due to material friction, resulting in a change in the material flow rate; the seal of the liquid material pump is worn, causing flow leakage, which may lead to significant differences in the composition of each batch of brick blanks. This difference is reflected in the product quality, manifested as insufficient strength of some brick blanks, which are prone to fracture during building construction, affecting the safety of the building structure; or uneven pore distribution, reducing the heat insulation and sound insulation performance of the brick body, and unable to meet the requirements of modern building energy conservation and comfort.

[0004] In terms of stirring and mixing, traditional equipment mostly adopts a single stirring rod or a stirring structure with the same rotation direction. Due to the limited stirring range of a single stirring rod in a relatively small area, it is difficult for materials to achieve comprehensive and sufficient exchange and fusion during the stirring process. When dealing with a large amount of materials, the materials far from the stirring rod may not be effectively stirred, resulting in uneven mixing. Although the stirring structure with the same rotation direction can promote the rolling and mixing of materials to a certain extent, due to the single rotation direction, the shear force and convection action on the materials are relatively weak. For some materials with high viscosity, such as high-viscosity gelling materials added with special additives, the traditional same-direction stirring structure is difficult to evenly disperse them in the liquid materials, and it is easy to form a lump structure, affecting the internal structure uniformity of the brick body. Moreover, with the refinement of the performance requirements for autoclaved aerated concrete bricks in the construction industry, for example, in some high-end building projects, strict requirements are put forward for indicators such as the coefficient of variation of the compressive strength and the uniformity of the thermal conductivity of the brick body. Obviously, the traditional stirring method cannot meet the mixing requirements of such high-precision formulas.

[0005] Therefore, a solid-liquid batching equipment for autoclaved aerated concrete brick production is proposed to solve the above problems. Summary of the Invention

[0018] Compared with the prior art, the present invention provides a solid-liquid batching device for autoclaved aerated concrete brick production, which has the following

[0019] Beneficial effects:

[0020] 1. Through the setting of the solid-liquid feeding ratio mechanism, driven by the bidirectional motor in the drive gear set and the cooperation of multiple gears in the drive gear set, the rotating plate is intermittently driven to rotate, and then the materials in the feeding pipe are transferred in equal amounts in batches, so that the conduit rotates periodically and intermittently, and the materials are put into the mixing cavity in preset weight batches for mixing and ratioing, avoiding the flow fluctuation problem of continuous feeding, improving the control period of the solid-liquid batching ratio, ensuring the consistency of the composition of each batch of brick blanks, improving the product quality stability, and the rotation of the conduit following the rotating plate can dynamically dredge the material channel, especially suitable for viscous materials or raw materials containing impurities, reducing the risk of blockage caused by agglomeration and material jamming during the conveying process of materials, ensuring the continuity of production. The separation design of the quantitative container and the mixing cavity can flexibly adjust the single-batch batching amount according to production requirements, and at the same time is convenient for equipment maintenance and cleaning, reducing the downtime caused by batching system failures.

[0021] 2. Through the design of the incomplete gears of the half gears in the driving gear set, when meshing with the integral gears, it can achieve the alternate cycle of rotation and pause at the blanking port. By adjusting the number of teeth and rotational speed of the half gears, the duration of each blanking and the intermittent period can be accurately controlled to meet the requirements of different processes for the batching rhythm. Moreover, the rotating conduit can make the material be thrown out in a spiral shape under the action of centrifugal force, avoiding the material accumulation or segregation caused by the traditional straight-drop blanking. In particular, it has a strengthening effect on the premixing of solid particles and liquids.

[0022] 3. Through the setting of the positive and reverse rotation mixing mechanism, under the synchronous drive of the bidirectional motor in the driving gear set, while promoting the intermittent and equal feeding of the material, with the cooperation of multiple bevel gears in the bevel gear set, the two side worms perform reverse rotational movements in the vertical direction, thereby driving the two groups of stirring rods to drive the paddle plates to perform reverse rotational stirring movements in the mixing cavity. It can generate a stirring flow field and acting force different from the traditional single direction, enabling the material to be subjected to forces from different directions during the stirring process, forming more complex and intense convection and shear effects in the stirring area. Different from solving the problem of easy caking of materials during solid-liquid mixing by increasing the stirring power or changing the shape of the stirring blades, etc., the forward rotation stirring shaft pushes the material to flow in one direction, and the reverse rotation stirring shaft pushes the material in the opposite direction. In this way, the material is continuously stretched, sheared, and mixed in the stirring area, effectively breaking the agglomeration force between the materials and preventing the formation of caking, ensuring the uniform mixing of solid-liquid materials.

[0023] 4. Through the coordinated use of the worm gear and the worm, the worm gear and the worm have self-locking characteristics. When the stirring rod rotates forward or backward, it can maintain stability by relying on its self-locking function, preventing the accidental rotation of the stirring rod due to the reaction force of the material. This greatly improves the stability and reliability of the stirring process. Furthermore, in the production of autoclaved aerated concrete bricks, when there is a large resistance during the material mixing, the cooperation of the worm gear and the worm provides a greater torque to meet the power requirements for stirring high-viscosity materials or a large amount of materials. Compared with some existing technologies where insufficient power leads to poor stirring effects, it can better adapt to complex material mixing working conditions and ensure the smooth progress of production.

[0039] Please refer to Figures 1 to 5 As shown:

[0040] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a solid-liquid batching device for producing autoclaved aerated concrete bricks, comprising: a mixing chamber 1, a cover 11 is arranged above the mixing chamber 1, a plurality of feeding pipes are connected to the mixing chamber 1, and the number of the feeding pipes 12 can also be specifically set according to the needs, a solid-liquid feeding and proportioning mechanism 2 is arranged at the top of the mixing chamber 1, and a forward and reverse rotation mixing mechanism 3 is arranged below the solid-liquid feeding and proportioning mechanism 2;

[0041] The solid-liquid material proportioning mechanism 2 is used to intermittently put the different ingredients into the mixing chamber 1 in batches according to the production of concrete bricks for mixing. The solid-liquid material proportioning mechanism 2 includes a rotating plate 21, which is rotatably connected to the mixing chamber 1. A through hole is opened at an eccentric position on one side of the rotating plate 21. A conduit 22 is fixedly connected to the lower surface of the rotating plate 21 where the through hole is opened. The conduit 22 is mainly used to connect the mixing chamber 1 with the feed pipe 12 to transfer the material to the mixing chamber 1. The conduit 22 is connected with the through hole, and a flap plate 23 is attached to the side of the conduit 22 away from the rotating plate 21. The flap plate 23 is mainly used to cooperate with the deflection column 24 and the inner concave ring 29 to intermittently block the lower end of the conduit 22. The middle part of the flap plate 23 is rotatably connected with the conduit 22, and the end of the flap plate 23 away from the conduit 22 is fixedly connected with the deflection column 24. A synchronous tube 25 is fixedly connected at the center of the lower surface of the rotating plate 21, and an annular groove 26 is provided on the upper surface of the inner cavity of the synchronous tube 25.

[0042] The solid-liquid material discharging and proportioning mechanism 2 also includes a function plate 27, which is fixedly connected to the mixing chamber 1. The function plate 27 is located directly below the rotating plate 21. Arc-shaped discharging ports 28 are provided on both sides of the function plate 27. An inner concave ring 29 is fixedly connected to the upper surface of the middle part of the function plate 27. The inner concave ring 29 is mainly used to control the opening and closing of the conduit 22 through two symmetrically arranged inner concave groove surfaces, and then to transport the materials in batches and in equal amounts to the mixing chamber 1 for mixing. The inner concave ring 29 is symmetrically provided with two inner concave arc grooves on one side close to the function plate 27. The deflection column 24 is slidably connected to the lower surface of the inner concave ring 29 and the deflection column 24 is in conflict with the lower surface of the inner concave ring 29. The function plate 2 A driving gear set 210 is arranged in the middle part of 7. The driving gear set 210 is mainly used for the cooperation of multiple gears to intermittently control the synchronous tube 25 to rotate. The driving gear set 210 is composed of a bidirectional driving device, a half gear, and an eccentric gear. A control rod 211 is fixedly connected to the upper surface of the eccentric gear in the driving gear set 210. The end of the control rod 211 away from the eccentric gear is slidably connected in the annular groove 26. An internal gear 212 is fixedly connected to the bottom of the inner ring of the synchronous tube 25. The internal gear 212 is meshed with the driving gear set 210. The bidirectional driving device in the driving gear set 210 is electrically connected to an external controller, and the synchronous tube 25 is rotatably connected to the function board 27.

[0043] For further examples, please refer to Figures 6 to 8 As shown:

[0044] The forward and reverse rotation mixing mechanism 3 is used for performing forward and reverse rotation deep mixing of solid and liquid ingredients for the materials put into the mixing chamber 1. The forward and reverse rotation mixing mechanism 3 includes a working chamber 31. The working chamber 31 is mainly used to protect the internal structure. The working chamber 31 is fixedly connected to the center of the function plate 27. The end of the driving gear set 210 away from the synchronous tube 25 is rotatably connected to the bevel gear set 32. The bevel gear set 32 ​​includes two transverse bevel gears and one vertical bevel gear. The upper end of the vertical bevel gear in the bevel gear set 32 ​​is fixedly connected to the output shaft of the driving gear set 210.

[0045] The forward and reverse rotation mixing mechanism 3 also includes a worm gear 33. The two worm gears 33 are mainly used to perform forward and reverse rotation respectively so that the stirring rod 35 can rotate forward and reversely, thereby mixing the internal solid-liquid materials to avoid problems such as caking. The worm gear 33 is fixedly connected to one end of the two transverse bevel gears in the bevel gear set 32 ​​away from the vertical bevel gear. One side of the two worm gears 33 is transmission-connected to a worm 34. Two worm gears 34 are symmetrically arranged around the axis of the working chamber 31. The worm 34 is rotatably connected in the working chamber 31. The lower ends of the two worm gears 34 extend through the working chamber 31 and are fixedly connected to the stirring rod 35. The outer ring of the stirring rod 35 is fixedly connected to a paddle plate 36. The paddle plates 36 are arranged in groups of three around the stirring rod 35, and there are multiple groups of paddle plates 36.

[0046] Everything in the above example works like this:

[0047] In the initial state: solid and liquid materials are transported in the conveying pipe 12, the rotating plate 21 blocks the lower pipe of the conveying pipe 12, the built-in power supply of the driving gear set 210 is not started, and the half gear and the eccentric gear in the driving gear set 210 are not meshed.

[0048] The following is the working process of the solid-liquid material proportioning mechanism 2 for intermittently feeding equal amounts of different ingredients into the mixing chamber 1 in batches for mixing according to the production of concrete bricks:

[0049] During use, solid and liquid materials are respectively conveyed through the feed pipe 12. The built-in power supply of the driving gear set 210 is started by an external controller. The output shaft drives the half gear in the driving gear set 210 to rotate forward. Then, when the half gear rotates forward, it gradually meshes with the eccentric gear in the driving gear set 210. Under the meshing action, the eccentric gear in the driving gear set 210 is pushed to rotate in a rotational motion opposite to that of the half gear. Through meshing transmission, the rotation of the eccentric gear in the driving gear set 210 drives the internal gear 212 to mesh with it, thereby causing the internal gear 212 to rotate forward. Under the forward rotational motion of the internal gear 212, since the synchronous pipe 25 is fixedly connected to it, the forward movement of the internal gear 212 synchronously drives the synchronous pipe 25 to rotate forward. And through the fixed connection between the synchronous pipe 25 and the function plate 27, the function plate 27 is synchronously driven to rotate forward with the synchronous pipe 25 as the axis. The forward rotation of the synchronous pipe 25 synchronously causes the through hole opened at its eccentric position to gradually rotate to directly below the feed pipe 12. When the through hole opened on the rotating plate 21 rotates to directly below the feed pipe 12, the materials inside the feed pipe 12 are gradually infused into the conduit 22 for storage. At this time, since the deflection column 24 abuts against the plane of the lower surface of the concave ring 29, the turning cover plate 23 fits against the lower surface of the conduit 22 to block it, so that the conduit 22 temporarily forms a storage cavity to store the materials conveyed by the feed pipe 12. And because the volume of the conduit 22 is a fixed value, the solid and liquid materials conveyed in the feed pipe 12 are equally divided and packaged. Under the continuous forward rotational motion of the rotating plate 21, the rotating plate 21 drives the conduit 22 to gradually separate from the feed pipe 12. At the same time, the deflection column 24 slides on the lower surface of the concave ring 29. When continuously rotating forward, the deflection column 24 fits against the concave surface opened on the lower surface of the concave ring 29. Under the action of the concave surface, the deflection column 24 deflects towards the direction close to the concave ring 29. Since the turning cover plate 23 is rotatably connected to the middle of the conduit 22, the upward deflection of the deflection column 24 causes the turning cover plate 23 at the other end to deflect downward, opening the conduit 22, so that the materials stored in the conduit 22 flow into the mixing cavity 1 for mixing. The conduit 22, the turning cover plate 23, and the deflection column 24 can be symmetrically arranged in two groups centered on the axis of the rotating plate 21 according to actual needs.

[0050] Through the setting of the solid-liquid feeding ratio mechanism 2, driven by the bidirectional motor built in the driving gear set 210 and in cooperation with the design of multiple gears in the driving gear set 210, the rotating plate 21 is intermittently driven to rotate, and then the materials in the feeding pipe 12 are transferred in equal amounts in batches, so that the conduit 22 rotates periodically and intermittently, and the materials are put into the mixing cavity 1 in preset weight batches for mixing ratio, avoiding the flow fluctuation problem caused by continuous feeding, improving the control period of the solid-liquid batching ratio, ensuring the consistency of the composition of each batch of brick blanks, enhancing the product quality stability, and the rotation of the conduit 22 following the rotating plate 21 can dynamically dredge the material channel, especially suitable for viscous materials such as cement, fly ash or raw materials containing impurities, reducing the risk of blockage caused by agglomeration and jamming of materials during transportation, ensuring the continuity of production. The separation design of the quantitative container and the mixing cavity 1 can flexibly adjust the single-batch batching amount according to production requirements, such as by replacing quantitative containers with different volumes, and at the same time facilitating equipment maintenance and cleaning, reducing the downtime caused by batching system failures.

[0051] Furthermore, the design of the non-integral gear of the half gear in the driving gear set 210 can achieve the alternate cycle of rotation pause at the feeding port when meshing with the overall gear. By adjusting the number of teeth and rotation speed of the half gear, the single feeding duration and intermittent cycle can be accurately controlled to meet the requirements of different processes for the batching rhythm. And the rotating conduit 22 can make the materials be thrown out in a spiral shape under the action of centrifugal force, avoiding the material accumulation or segregation caused by the traditional straight-down feeding, especially having a strengthening effect on the premixing of solid particles such as sand grains and liquids.

[0052] Please refer to the above working process Figures 1 to 5 。

[0053] The following is the working process of the positive and negative rotation mixing mechanism 3 for deep mixing of solid and liquid materials with positive and negative rotation for the materials put into the mixing cavity 1:

[0054] During use, since the built-in power supply of the driving gear set 210 is implemented as a bidirectional driving motor, while the conduit 22 separates and intermittently feeds materials, the bevel gear set 32 is synchronously started to rotate. The vertical bevel gear in the bevel gear set 32 rotates forward, and at the same time, under the transmission effect, the driving lateral vertical wheels on both sides rotate in positive and negative directions respectively. Then, through the positive and negative rotation of the two lateral bevel gears, the transmission reaches the two worm wheels 33 at both ends to rotate synchronously in positive and negative directions respectively. Continuing under the meshing transmission cooperation, the rotation of the two worm wheels 33 respectively drives the two worm shafts 34 meshing with them to rotate in opposite directions. Through the positive and negative rotation of the two worm shafts 34, the two stirring rods 35 fixedly connected with them rotate in opposite directions synchronously, thereby driving a plurality of paddle plates 36 arranged on the outer circle to perform multi-directional turbulent rotation on the mixing of solid and liquid materials in the mixing cavity 1.

[0055] With the setting of the forward and reverse mixing mechanism 3, under the synchronous drive of the bidirectional motor in the drive gear set 210, while promoting the intermittent and equal feeding of materials, with the cooperation of multiple bevel gears in the bevel gear set 32, the two side worms 34 perform reverse rotational movements in the vertical direction, thereby driving the two groups of stirring rods 35 to drive the paddle plates 36 to perform reverse rotational stirring movements in the mixing cavity 1. This can generate a stirring flow field and acting force different from the traditional single direction, enabling the materials to be subjected to forces from different directions during the stirring process, forming more complex and intense convection and shear effects in the stirring area. Different from solving the problem that materials are prone to caking during solid-liquid mixing by increasing the stirring power or changing the shape of the stirring paddle, the forward rotation stirring shaft pushes the materials to flow in one direction, and the reverse rotation stirring shaft pushes the materials in the opposite direction. In this way, the materials are continuously stretched, sheared, and mixed in the stirring area, effectively breaking the agglomeration force between the materials, preventing the formation of caking, and ensuring the uniform mixing of solid-liquid materials.

[0056] Furthermore, with the coordinated use of the worm gear 33 and the worm 34, the worm gear 33 and the worm 34 have a self-locking property. When the stirring rod 35 rotates forward or backward, it can maintain stability relying on its self-locking function, preventing the stirring rod 35 from accidentally rotating due to the reaction force of the materials, greatly improving the stability and reliability of the stirring process. Furthermore, in the production of autoclaved aerated concrete bricks, when there is a large resistance during material mixing, the cooperation of the worm gear 33 and the worm 34 provides a greater torque to meet the power requirements for stirring high-viscosity materials or a large amount of materials. Compared with some existing technologies where insufficient power leads to poor stirring effects, it can better adapt to complex material mixing conditions and ensure the smooth progress of production.
