Description

Technical Field

[0001] This utility model relates to the field of concrete production, specifically to a concrete product raw material mixing mechanism. Background Technology

[0002] The production of concrete products such as autoclaved aerated concrete blocks typically involves processes such as batching and mixing, pouring, static curing, cutting, and high-pressure steam curing.

[0003] The uniformity of the slurry is particularly critical during the mixing stage. Insufficient mixing before pouring can lead to problems such as stratification, clumping, and localized thickening, directly affecting the porosity of the green body and the final product's performance. Existing mixing equipment typically consists of a mixing shaft inside the tank, with several radially extending blades mounted on it. As the shaft rotates, the blades propel the slurry, achieving uniform mixing. However, the current mixing process is monotonous, requiring a long mixing time and impacting production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the above problems by providing a concrete product raw material mixing mechanism that can improve production efficiency.

[0005] To achieve the above objectives, the present invention provides a concrete product raw material mixing mechanism, comprising a horizontally arranged tank with an openable discharge port on its peripheral wall, the tank rotating around its axis; and a feeding pipe coaxially arranged with the tank, one end of which extends into the tank. The feeding pipe has a feeding port on its upper surface outside the tank and a feeding port on its lower surface inside the tank. A baffle plate for cleaning the tank sidewall is provided on the inner wall of the feeding pipe, moving radially along the tank under the action of a protrusion. The protrusion is located on the inner sidewall of the tank, with an arc-shaped side facing the baffle plate and a vertical side facing away from the arc-shaped side. A feeding mechanism is provided inside the feeding pipe. During tank rotation, the protrusions periodically contact the end face of the baffles, causing the baffles to move along the arc surface. The baffles contract radially along the tank under the pushing force of the protrusions. After the protrusions pass the baffles, the baffles immediately return to their original position and extend under elasticity, generating a contraction-extension motion to fully agitate the slurry and shorten the mixing time. Simultaneously, the outer end face of the baffles contacts the inner wall of the tank, allowing the baffles to scrape off some of the material adhering to the inner side wall during tank rotation. As the tank rotates, the contraction and extension of the baffles periodically impact the tank side wall, further reducing the amount of material adhering to the inner wall and decreasing the cleaning workload.

[0006] Furthermore, in order to enable the spoiler to extend and retract radially along the tank body, the spoiler includes a fixed part and a movable part. The fixed part is fixedly installed on the side wall of the feed pipe, and its outer end face is provided with a receiving groove facing the side wall of the tank body. One end of the movable part is inserted into the receiving groove and connected to a spring. The depth direction of the receiving groove and the spring are both arranged radially along the tank body. The other end of the movable part extends out of the receiving groove and extends toward the peripheral wall of the tank body.

[0007] Furthermore, to precisely control the feeding amount, the feeding mechanism includes a feeding screw coaxially arranged with the feeding tube, and the feeding screw rotates under the drive of the feeding motor.

[0008] Furthermore, the tank is disposed inside the shell, and the tank and the shell are connected by a bearing. A discharge port is provided on the lower surface of the peripheral wall of the shell.

[0009] Furthermore, the discharge port is located at the lowest point of the inner wall of the tank in the longitudinal cross-sectional direction.

[0010] The beneficial effects of this invention are as follows: During the rotation of the tank, the baffle plate retracts radially along the tank body under the pushing force of the protrusion; after the protrusion passes the baffle plate, the baffle plate immediately returns to its original position and extends under the action of elasticity, thereby generating a radial extension and contraction motion along the tank body to fully agitate the slurry and shorten the mixing time. At the same time, the outer end face of the baffle plate contacts the inner wall of the tank, so that when the tank rotates, the baffle plate can scrape off some of the material adhering to the inner side wall of the tank. During the rotation of the tank, as the baffle plate extends and contracts, it periodically impacts the side wall of the tank body, further reducing the amount of material adhering to the inner wall of the tank body and reducing the amount of cleaning work.

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0015] Example 1, as Figure 1-2 As shown, the structure of this embodiment is as follows: a concrete product raw material mixing mechanism, including a horizontally arranged tank 1 and a feeding pipe 3. An openable discharge port 2 is provided on the peripheral wall of the tank 1. The tank 1 is disposed within a housing 14, and the tank 1 and housing 14 are connected by bearings spaced apart along the axial direction of the tank 1. A discharge port 15 is provided on the lower surface of the peripheral wall of the housing 14. When the discharge port 2 rotates to the lower end of the tank 1, the discharge port 2 is directly above the discharge port 15. The inner diameter of the discharge port is not less than the inner diameter of the discharge port 2. The tank 1 rotates under the action of a motor, which can be disposed outside the housing 14. The output shaft of the motor extends into the housing and is connected to the tank 1 for transmission. In this embodiment, a concentric gear ring is provided on the end face of the tank 1, and a gear meshing with the gear ring is provided on the output shaft of the motor. The longitudinal section of the tank body 1 and the shell 14 is a cone shape, which is small at both ends and large in the middle, and the discharge port 2 is opened at the lowest point of the inner wall of the tank body 1 in the longitudinal section direction.

[0016] The feeding pipe 3 is coaxially arranged with the tank body 1. One end of the feeding pipe 3 extends into the tank body 1. A bearing is provided at the connection between the feeding pipe 3 and the tank body 1. A feeding port 4 is provided on the upper surface of the feeding pipe 3 outside the shell 14, and a feeding port 5 is provided on the lower surface of the feeding pipe 3 inside the tank body 1. A feeding mechanism 9 is provided inside the feeding pipe 3. The feeding mechanism 9 can be a pusher plate driven by a hydraulic cylinder, etc. In this embodiment, the feeding mechanism 9 includes a feeding screw coaxially arranged with the feeding pipe. The threaded section of the feeding screw extends beyond the feeding port 5. The feeding screw rotates under the drive of the feeding motor 13.

[0017] The feed pipe 3 is located inside the tank 1 and has baffles 6 on its inner wall for cleaning the side wall of the tank 1. Multiple baffles 6 are arranged in a circular array around the axis of the tank 1, and in addition to the circular arrangement, the baffles 6 can also be arranged at intervals along the axis of the tank 1. The baffles 6 include a fixed part 10 and a movable part 11. The fixed part 10 is fixedly installed on the side wall of the feed pipe 3, and its outer end face has a receiving groove facing the side wall of the tank. One end of the movable part 11 is inserted into the receiving groove and connected to a spring 12. Multiple springs 12 can be arranged at intervals along the axial direction of the tank. The other end of the movable part 11 extends out of the receiving groove toward the peripheral wall of the tank 1.

[0018] The spoiler 6 moves radially along the tank body 1 under the action of the protrusion 7. The protrusion 7 is located on the inner wall of the tank body 1. The side of the protrusion 7 facing the spoiler 6 is an arc surface, with the center of the arc surface facing the outside of the tank body 1. The side facing away from the arc surface is a vertical surface 8. The arc surface and the vertical surface 8 are connected by an inclined plane, which extends along the tangent of the arc surface. Figure 2 As shown, tank 1 rotates counterclockwise.

[0019] The specific mixing process is as follows: the mixed raw materials are fed into the feeding pipe 3 through the feeding port 4, and then the materials move towards one side of the tank 1 under the push of the feeding mechanism 9 until they enter the tank 1 through the feeding port 5. The discharge port 2 remains closed during the mixing and material addition process.

[0020] During stirring, the tank 1 rotates. When the protrusion 7 moves to the baffle 6, the movable part 11 first contacts the arc surface and is pushed back into the receiving tank by the gradually increasing height of the arc surface. However, when the protrusion 7 passes the baffle 6, the movable part 11 loses its restriction, and the spring 12 immediately pushes the movable part 11 out. This allows the baffle 6 to fully stir the material in the tank 1 during the rotation of the tank 1. At the same time, the protrusion 7 can also play a role in turbulence and drive the material to move, so that the material is fully mixed, thereby reducing the stirring time.

[0021] When maintaining tank 1, as tank 1 rotates, the moving part 11 comes into instantaneous contact with the tank wall, thereby generating intermittent impacts on tank 1 to vibrate off some of the material adhering to tank 1, which reduces the amount of cleaning work to a certain extent.
