[0002] Fly ash is a pozzolanic material. Fly ash recycled concrete is a kind of concrete with waste fly ash as the main admixture. It is an environment-friendly concrete with good fluidity during construction, easy to fill, high compactness, and can reduce the amount of cement required for the project and the cost. Moreover, fly ash concrete can also slowly release carbon dioxide gas and reduce environmental pollution. The common batching components of fly ash recycled concrete are cement, fly ash, sand, and stones, and their proportions are adjusted according to usage requirements. In order to facilitate the batching and processing of fly ash recycled concrete, a fly ash recycled concrete batching and mixing device is needed.

[0003] Since the fly ash recycled concrete batching and mixing device often requires the user to pre-weigh and take out cement, fly ash, sand, and stones before specific use, and then pour them into the mixing tank of the fly ash recycled concrete batching and mixing device in sequence, and realize the mixing process of raw materials through the mixing structure composed of the motor and the stirring shaft on the mixing tank. This makes the device not easy to meet the classified and weighing type automatic feeding operation, affects the batching efficiency and intelligence level, and is inconvenient to operate, and can no longer meet people's needs. Therefore, we propose a new type of fly ash recycled concrete automatic batching and mixing device to solve the above-mentioned problems. Content of the Utility Model

[0030] During use, when the powder vacuum feeding mechanism 3 is utilized, the vacuum pump 10 is started and cooperates with the feeding tank 12, so that the inside of the feeding tank 12 has a negative pressure, and the gas inside the powder pre-storage tank 8 can be pumped into the feeding tank 12 through the material guide pipe 11 and then discharged from the bottom of the feeding tank 12 and guided into the mixing tank 1, realizing the automatic vacuum feeding operation of the powdery raw materials;

[0040] The working principle of the present utility model is as follows: First, an external power supply and a control device are connected. The user can divide the four raw materials, namely cement, coal ash, sand, and stones, used for proportioning fly ash recycled concrete, into two categories, namely the two types of powdery raw materials, i.e., cement powder and coal ash, and the two types of granular raw materials, i.e., sand and stones. Then, the powdery raw materials are respectively poured into the powder pre-storage box 8 inside the powder vacuum feeding mechanism 3 arranged at both ends of the mixing tank 1 for pre-storage, and the granular raw materials are respectively poured into the granular material pre-storage box 15 inside the granular material feeding mechanism 5 arranged on both sides of the mixing tank 1 for pre-storage. This enables the device to perform classified automatic feeding operations according to the characteristics of the four raw materials used for preparing fly ash recycled concrete, improving the efficiency and intelligence of batching. At the same time, when the powder vacuum feeding mechanism 3 is in use, the vacuum pump 10 starts and cooperates with the function of the feeding tank 12, so that the inside of the feeding tank 12 has a negative pressure, and the gas inside the powder pre-storage box 8 can be pumped into the feeding tank 12 through the guide pipe 11 and then discharged from the bottom of the feeding tank 12 and guided into the mixing tank 1 to achieve the automatic vacuum feeding operation of the powdery raw materials. Secondly, the motor structure equipped on the inclined screw feeder 13 of the granular material feeding mechanism 5 is started, and the granular raw materials inside the granular material pre-storage box 15 arranged at its output end are automatically and evenly sent upward in a spiral manner and then introduced into the mixing tank 1 through the feeding pipe 14, enabling the device to achieve the automatic spiral feeding operation of the granular raw materials. Moreover, by using the controller externally connected to the device, two motors 17 can be started to drive the automatic sealing plate 16 to automatically flip to expose the through-hole inside the feeding seat 4 and automatically reset, making it convenient for the feeding seat 4 to achieve automatic opening and closing control, which is convenient for the feeding operation of the mixing tank 1.

Subsequently, two stepping motors 2 are started, and the mixing tank 1 with the feeding port closed is flipped at a frequency of 180 degrees each time. The rotation of the mixing tank 1 drives the rolling movement of the materials inside the mixing tank 1, which is beneficial to fully mixing and processing the various raw material products for batching.
