Description

Technical Field

[0001] This application relates to the technical field of concrete admixture mixing, and specifically to an environment-friendly premixed concrete dry mixing device. Background Technique

[0002] Concrete admixtures are powdery minerals that are added during concrete production to improve the performance of concrete, save water, and adjust the concrete strength grade. They are natural or artificial substances that can improve the performance of concrete. Generally, concrete admixtures include fly ash, granulated blast furnace slag powder, zeolite powder, silica fume, etc. Currently, in the prior art, when producing concrete, fly ash, granulated blast furnace slag powder, zeolite powder, silica fume and other admixtures need to be added. To ensure that the admixtures are fully incorporated during the mixing process and prevent the admixtures from aggregating into lumps, long-term mixing is required during the mixing of concrete production, resulting in a long production cycle of concrete. Generally, the admixtures are mixed before being added to the concrete.

[0003] A prior patent (publication number: CN219667049U) discloses a dry mixing device for concrete admixtures, which includes a bearing frame. A stepping motor is fixedly connected to the inclined side of the bearing frame. The output shaft of the stepping motor is connected to a mixing barrel through a coupling. The outer wall of the mixing barrel is processed with spiral grooves. A limiting connecting rod is fixedly connected to the inclined side of the bearing frame. A movable folding rod is slidably connected to the outer wall around the limiting connecting rod. One side outer wall of the vertical plate of the movable folding rod is rotatably connected to a movable ball through a connecting rod. The movable ball is slidably connected inside the spiral groove. A fixed connecting rod is fixedly connected to the bottom of the horizontal plate of the movable folding rod. In the design of the present utility model, the movable ball moves in the spiral groove on the mixing barrel, which causes the movable folding rod to move up and down, so that the fixed connecting rod and the mixing mechanism on the fixed connecting rod stir the concrete admixtures up and down, while the mixing barrel stirs the concrete admixtures horizontally, improving the dispersing effect of the concrete admixtures.

[0004] However, during the use of the above dry mixing device, since the mixed materials are prone to generate a large amount of dust during mixing, the above device cannot seal the mixing barrel, which is likely to pollute the environment and affect the health of workers. Secondly, during the use of the above device, workers often need to control the weight of each material based on experience, which is likely to affect the performance of the concrete. Summary of the Utility Model

This design effectively avoids the leakage of dust generated during the mixing process, significantly reduces environmental pollution, and protects the physical health of workers. By setting the weighing device, the weight of the materials inside the mixing tank can be monitored in real time. This function enables operators to accurately control the addition amount of various admixtures, avoiding the proportioning errors caused by relying on experience judgment in the traditional method, thereby ensuring the stability of the concrete performance and improving the quality of the concrete.

[0009] Further, a support frame is fixedly connected to the outer surface of the mixing tank.

[0010] Through the above solution, by setting the support frame, the purpose of supporting the mixing tank can be achieved.

[0011] Further, a weighing device is installed on the upper surface of the bottom plate, and the top end of the weighing device is fixedly connected to the bottom end of the support frame.

[0012] Through the above solution, by setting the weighing device, the weight of the materials inside the mixing tank can be monitored.

[0013] Further, a fixing frame is fixedly connected to the inner wall of the support frame, and a motor is fixedly installed inside the fixing frame. The output end of the motor is fixedly connected to the bottom end of the stirring shaft.

[0018] With the above solution, through the setting of the handle, it is convenient to use the opening and closing cover plate.

[0019] Furthermore, a discharge pipe is fixedly connected to the bottom end of the mixing tank.

[0020] With the above solution, through the setting of the discharge pipe, it is convenient to unload the materials.

[0021] Furthermore, a valve is installed at the bottom end of the discharge pipe.

[0022] With the above solution, through the setting of the valve, the purpose of closing the discharge pipe can be achieved.

[0023] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0024] For this environmentally friendly premixed concrete dry mixing device, by setting a rotatable cover plate on the top of the mixing tank and connecting it to the discharge port of the screw elevator through a corrugated pipe, a fully enclosed operation during the material transmission process is realized. This design effectively avoids the leakage of dust generated during the mixing process, significantly reduces environmental pollution, and protects the health of workers.

[0034] Please refer to Figure 1 、 Figure 2 and Figure 3 A weighing device 11 is installed on the upper surface of the bottom plate 1. The top end of the weighing device 11 is fixedly connected to the bottom end of the support frame 10. Through the setting of the weighing device 11, the weight of the materials inside the mixing tank 2 can be monitored. A fixing frame 12 is fixedly connected to the inner wall of the support frame 10. A motor 13 is fixedly installed inside the fixing frame 12. The output end of the motor 13 is fixedly connected to the bottom end of the stirring shaft 3.

[0035] Please refer to Figure 1 、 Figure 2 and Figure 4, a discharge pipe 16 is fixedly connected to the bottom end of the mixing tank 2.

[0036] In an environment-friendly premixed concrete dry-mixing device in this embodiment, by providing a rotatable cover plate 8 at the top of the mixing tank 2 and connecting it to the discharge port 7 of the screw elevator 5 through a corrugated pipe 9, a fully enclosed operation during the material transmission process is realized. This design effectively avoids the leakage of dust generated during the mixing process, significantly reduces environmental pollution, and protects the physical health of workers. By providing a weighing device 11, the weight of the material inside the mixing tank 2 can be monitored in real time. This function enables operators to accurately control the addition amount of various admixtures, avoiding the proportioning errors caused by relying on experience judgment in the traditional method, thereby ensuring the stability of the concrete performance and improving the quality of the concrete.

[0037] The working principle of the above embodiment is as follows: First, start the screw elevator 5, and send the concrete admixtures to be mixed, such as fly ash, slag powder, etc., into the screw elevator 5 one by one through the feed port 6. As the screw blades rotate, the material is gradually lifted to the top and discharged through the discharge port 7. At this time, the corrugated pipe 9 serves as a connection channel, smoothly guiding the material into the mixing tank 2 while avoiding the problem that the direct connection may interfere with the normal closing of the cover plate 8. After the material enters the mixing tank 2, the cover plate 8 can ensure the sealing of the mixing process and reduce dust leakage. Subsequently, start the motor 13 installed on the fixed frame 12 inside the support frame 10. The motor 13 drives the stirring shaft 3 to rotate, driving a plurality of stirring blades 4 fixed on the outer surface of the stirring shaft 3 to rotate together. The rotation of the stirring blades 4 realizes the efficient mixing of the material, ensuring that the admixtures can be evenly distributed in the concrete and avoiding the occurrence of agglomeration phenomena. During the mixing process, the weighing device 11 monitors the weight change of the material inside the mixing tank 2 in real time. Operators can accurately adjust the addition amount of various admixtures by controlling the feeding amount of the screw elevator 5 according to the preset proportioning requirements, thereby avoiding the proportioning errors caused by relying on experience judgment in the traditional method.
