Description

Technical Field

[0001] This utility model relates to the technical field of air-entraining agent dispensing devices, specifically a high-efficiency air-entraining agent dispensing device. Background Technology

[0002] Air-entraining agents, also known as air-adding agents, are hydrophobic surfactants that, when dissolved in water, generate a large number of tiny bubbles during concrete mixing. They are mainly used in concrete structures requiring high frost resistance, such as dams, high-grade highways, and cooling towers in thermal power plants. Product varieties include rosin resins and alkylbenzene sulfonates, with common dosages ranging from 50 to 500 ppm by weight of cement.

[0003] Air-entraining agents can improve the fluidity, cohesiveness, and water retention of concrete mixtures, and enhance freeze-thaw resistance. However, they increase air content, leading to a decrease in compressive strength (approximately 3%-5% reduction in strength for every 1% increase in air content). This formulation is suitable for pumped concrete, de-icing salt pavements, and high-durability projects. When using it, the air content must be controlled through testing to avoid excessive addition.

[0004] The current standard air-entraining agent is packaged in 20KG drums. This type of air-entraining agent is manually added, which is inconvenient to handle and difficult to add. Utility Model Content

[0005] The purpose of this invention is to provide a highly efficient air-entraining agent delivery device to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency air-entraining agent dispensing device, comprising a carrier plate and a back plate, wherein the back plate is vertically disposed on one side of the top of the carrier plate, and a rotatable feeding plate is installed on the other side of the carrier plate. Multiple rollers are installed on the bottom surface of the carrier plate, and a recessed roller mounting groove is provided at the center of the top of the carrier plate. Multiple rollers are installed at equal intervals in the roller mounting groove. A connecting shaft I is fixed on each of the two ends of the feeding plate, and a fixing arm is sleeved on the connecting shaft I. A hook is provided on the other end of the fixing arm away from the connecting shaft I. A connecting shaft II that cooperates with the fixing arm is fixed on each of the two ends of the back plate, and a push handle is fixed on the upper part of the side of the back plate opposite to the carrier plate.

[0007] Preferably, a groove is provided in the middle of the side surface of the back plate facing the carrier plate, and a gas-entraining agent barrel flipping device is installed in the groove. The gas-entraining agent barrel flipping device consists of a mounting plate, a rubber pad and a flipping handle. Limiting ribs are provided on both sides of the mounting plate. The rubber pad is fixed to one side of the mounting plate and the flipping handle is fixed to the top of the mounting plate.

[0008] Preferably, a discharge guide plate is fixed at the middle position of one end surface of the carrier plate.

[0009] Preferably, the top surface of the feeding plate is inclined on the side away from the carrier plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the gas-entraining agent barrel is placed horizontally and moved to the carrier plate via the feeding plate. Then, the fixed arm is pulled and hung on the connecting shaft two, which can drive the feeding plate to flip and lift, and restrict the gas-entraining agent barrel on the carrier plate. The gas-entraining agent barrel is moved by pushing this device. After the gas-entraining agent barrel is moved to the designated position, the gas-entraining agent barrel is rotated so that the discharge port on the gas-entraining agent barrel is at the lowest position. Multiple rollers set on the carrier plate can facilitate manual rotation of the gas-entraining agent barrel. Then, the sealing cover on the gas-entraining agent barrel is opened to allow the gas-entraining agent to flow out. This device realizes the transportation of the gas-entraining agent barrel while facilitating the rotation of the gas-entraining agent barrel, thereby adjusting the height of the discharge port on the gas-entraining agent barrel. When the gas-entraining agent is added, the gas-entraining agent barrel is always located on the carrier plate, which facilitates the transportation of empty barrels. The air-entraining agent tank tilting device installed on the back plate consists of a mounting plate, a rubber pad, and a tilting handle. The rubber pad can act as a buffer to reduce the impact of the air-entraining agent tank on the back plate when it is transported to the carrier plate. Since the outer wall of the air-entraining agent tank is attached to the rubber pad, the air-entraining agent tank can be rotated when the tilting handle is pulled upward, which makes it easy to adjust the height of the discharge port of the air-entraining agent tank. The unloading guide plate on the carrier plate can increase the dispensing distance of the air-entraining agent in this device. Attached Figure Description
