Description

Technical Field

[0001] This utility model belongs to the field of concrete mixing technology, specifically relating to a concrete construction mixing device. Background Technology

[0002] Concrete construction is the process of pouring concrete materials into structures that meet design requirements through a series of processes and technologies. During construction, concrete needs to be mixed. Existing mixing devices have long suffered from problems such as easy solidification of materials in low-temperature environments, uneven mixing leading to residue on the tank walls, and low heat energy utilization. Although traditional mixing equipment has attempted to improve this through simple heating or optimization of the mixing structure, the separation of the heating components from the mixing mechanism results in low heat transfer efficiency and makes it impossible to uniformly control the temperature of the concrete. In addition, there are gaps between the conventional mixing blades and the tank wall, making it difficult to effectively scrape off adhering materials. After the residue solidifies, it not only affects the mixing efficiency but also increases the cleaning burden. At the same time, existing equipment lacks a waste heat recovery structure, and the direct emission of high-temperature gases causes energy waste. These problems are more prominent, especially in winter construction or cold regions, which restricts the construction progress and the stability of concrete quality. There is an urgent need for a composite mixing device that integrates heating and anti-condensation, high-efficiency mixing, and heat energy recycling to overcome the technical bottlenecks.

[0021] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-5 The present invention provides a technical solution: a concrete construction mixing device, comprising a tank 1 for containing materials and a cover plate 2. The bottom of the cover plate 2 is fixed to the top of the tank 1, and a fixing frame 3 is fixed to the top of the cover plate 2. The cover plate 2 can reduce dust flying during the concrete mixing process. An anti-solidification mixing component 4 for mixing materials is fixedly installed on the inner wall of the top of the fixing frame 3. A portion of the anti-solidification mixing component 4 is located on the outside of the tank 1. A support leg 5 is fixed on the outside of the anti-solidification mixing component 4. A discharge pipe 6 is fixedly installed through the outside of the tank 1, and a plug is provided at the other end of the discharge pipe 6.

[0023] In actual use, the concrete raw materials are manually put into the tank 1 and a certain amount of water is added. Then, the anti-solidification mixing component 4 is controlled by an external controller. When the anti-solidification mixing component 4 is started, the concrete raw materials and water in the tank 1 can be fully mixed. The anti-solidification mixing component 4 can also heat the concrete to prevent it from solidifying in a low-temperature environment, thus improving the mixing efficiency of the concrete. When discharging the concrete into the tank 1, the plug at the other end of the discharge pipe 6 can be removed, making it convenient to use.

[0024] Furthermore, to enhance the stability and support strength of the mixing device, anti-slip pads are provided at the bottom of the support legs 5. The anti-slip pads are made of wear-resistant rubber material, which increases the friction with the ground and prevents the mixing device from sliding or shifting during operation, thereby improving the safety and stability of the mixing device. At the same time, the number and position of the support legs 5 are rationally designed according to the weight and distribution of the tank 1 and the mixing components to ensure the balance and stability of the overall structure.

[0025] As a technical optimization of this utility model, the anti-solidification mixing assembly 4 includes a driving component 401, a mixing component 402, and a heating component 403 to prevent concrete solidification. The driving component 401 is fixedly installed on the top inner wall of the fixed frame 3, the mixing component 402 is fixedly installed on the bottom of the driving component 401, the bottom of the heating component 403 is fixedly installed on the top of the cover plate 2, and the output end of the heating component 403 is rotatably installed on the top of the mixing component 402. A heat preservation frame 404 is fixed on the outside of the tank body 1, and an air outlet 405 is provided on the heat preservation frame 404. The fully utilized hot air can flow out through the air outlet 405. A connecting pipe 406 is rotatably installed on the bottom of the mixing component 402, and the other end of the connecting pipe 406 is inserted and fixed to the bottom of the heat preservation frame 404.

[0026] The driving component 401 consists of a motor, a driving gear, and a driven gear. The motor is fixedly mounted on the top inner wall of the fixed frame 3. The top of the driving gear is fixed on the motor output shaft. The driven gear is meshed on one side of the driving gear and can drive the connecting shaft to rotate stably. The stirring component 402 consists of a connecting shaft with a built-in cavity, a C-shaped stirring frame, and a reinforcing rod. The top of the connecting shaft is fixedly mounted on the bottom of the driven gear. The C-shaped stirring frame is fixed on the outside of the connecting shaft. The outside of the C-shaped stirring frame contacts the inner wall of the tank 1, which facilitates cleaning of the inner wall of the tank 1. The reinforcing rod is fixedly mounted inside the C-shaped stirring frame. The heating component 403 consists of a heating box and a gas supply pipe. The bottom of the heating box is fixedly mounted on the top of the cover plate 2. A fan is installed on one side of the heating box. A heating tube with a heating wire inside is installed inside the heating box to heat the air. One end of the gas supply pipe is fixed to the other side of the heating box, and the other end of the gas supply pipe is rotatably mounted on the top of the connecting shaft.

[0027] In use, the motor of the drive component 401 drives the connecting shaft and the C-shaped mixing frame on the outside to rotate at high speed through the meshing of the active gear and the driven gear. During the rotation, the C-shaped mixing frame comes into close contact with the inner wall of the tank 1, and the scraping action of its edges removes the concrete residue attached to the tank wall, ensuring the efficiency and uniformity of the mixing process. At the same time, the reinforcing rod further enhances the mixing force, making the materials evenly mixed. Meanwhile, the heating box in the heating component 403 introduces external air through a fan, which is heated by the internal heating tube to form hot air. The hot air is delivered to the top of the connecting shaft through the air supply pipe. The hot air flows downward along the built-in cavity of the connecting shaft. The hot air can flow into the interior of the insulation rack 404 through the connecting pipe 406, and then be discharged from the air outlet 405. The setting of the insulation rack 404 allows the hot air to be reused on the outside of the tank 1, which not only fully heats the concrete inside the tank 1 and prevents the concrete from solidifying in a low-temperature environment, but also significantly reduces the waste of heat.
