Description

Technical Field

[0001] The utility model relates to the technical field of casting material preparation, in particular to an integrated production device for baking-free self-flowing casting material. Background Art

[0002] Refractory castables refer to a mixture of refractory aggregates, binders and admixtures, which are mixed with water to form a mud material that can be constructed by pouring. The difference from other amorphous refractory materials is that refractory castables have a certain coagulation and hardening time after construction, so after pouring and forming, they need to be cured for a certain period of time before demoulding, and then after a suitable period of natural curing, they can be put into baking and use.

[0003] Refractory castables are a mixture of refractory aggregates, powders and binders. After adding water or other liquids, they are suitable for construction by pouring and vibration methods. They can also be prefabricated into prefabricated parts with specified shapes and sizes for the construction of industrial furnace linings. In order to improve the physical and chemical properties and construction performance of refractory castables, appropriate amounts of additives are often added, such as plasticizers, dispersants, accelerators, retarders, expanders, debonders and gelling agents, etc.

[0004] The preparation equipment of refractory castables mainly includes the mixing of various powders and the filling after mixing. The existing production equipment includes mixing equipment and filling equipment. The two equipment cannot be highly integrated. After the mixed powder is prepared, it needs to be transported, which increases labor costs and reduces production efficiency. Therefore, an integrated production equipment capable of powder mixing and filling is needed. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an integrated production equipment for baking-free self-flowing castable material.

[0006] The technical solution of the utility model is: an integrated production equipment for baking-free self-flowing castable material, including a fixed frame, a stirrer is fixedly connected to the upper left side of the fixed frame, a feed trough is fixedly connected to the upper left side of the stirrer, a storage box is provided at the lower right side of the stirrer, a filler is fixedly connected at the lower part of the storage box, and the filler is fixedly connected to the fixed frame.

[0007] Furthermore, the agitator includes a mixing drum, a guide cover is hinged on the right side of the mixing drum, a guide mechanism for controlling the rotation of the guide cover is fixedly connected to the upper right side of the mixing drum, a mixing motor is fixedly connected to the left side of the mixing drum, a spiral stirring rod is rotatably connected inside the mixing drum, and the left end of the spiral stirring rod is drivingly connected to the output shaft of the mixing motor.

[0008] Description: The dual purpose of stirring and feeding is achieved through the forward and reverse rotation of the spiral stirring rod. When the spiral stirring rod rotates forward, the powder at the bottom is transported upward through the spiral stirring rod, and the powder moves downward under the action of gravity. The purpose of stirring and mixing is achieved through the up and down reciprocating motion of the powder. After the spiral stirring rod is reversed, the powder is discharged from the mixing drum under the action of gravity and the downward conveying of the spiral stirring rod.

[0010] Description: The closing and opening of the mixing drum discharge port is achieved through the guide mechanism. Due to the gravity of the powder, the opening and closing effect through the handover method is poor, and the closing and opening effect of the discharge port through rotation is better.

[0011] Furthermore, the filler includes a filling cylinder, the top of which is fixedly connected to the storage box, the left end of which is movably connected to a pneumatic rod, the fixed end of which is fixedly connected to the fixed frame, the telescopic end of which is movably connected to the inside of the filling cylinder, and the left end of which is hinged with a sealing cover.

[0012] Description: The telescopic end of the pneumatic rod moves to the left, and the sealing cover closes the right end of the filling cylinder under the action of gravity, forming a negative pressure in the filling cylinder. The sealing cover is tightly combined with the right end of the filling cylinder. The powder in the storage box is transported downward into the filling cylinder under the action of negative pressure and gravity. The telescopic end of the pneumatic rod moves to the right, pushing the powder in the filling cylinder to move to the right, pushing open the sealing cover, and filling the powder.

[0013] Furthermore, a conveyor belt is provided below the filler, and the conveyor belt is fixedly connected to the fixing frame.

[0014] Description: Conveyor belts help move bagged powders on a conveyor.

[0015] The beneficial effects of the utility model are:
