Description

Technical Field

[0001] The utility model belongs to the technical field of ceramsite sand production, and particularly relates to a raw material transfer and storage device for ceramsite sand. Background Art

[0002] The petroleum fracturing proppant - ceramsite sand is a ceramic particle product, which is made from high-quality raw materials such as bauxite and kaolin through multiple processes including crushing, grinding, granulation and high-temperature calcination. It has the characteristics of low density, high strength, strong conductivity and corrosion resistance. Before granulating the ceramsite sand, it is necessary to first grind the raw materials of the ceramsite sand by a ball mill to reduce the particle size of the raw materials, obtain a raw material powder with an outlet fineness of about 600 - 800 meshes, store the raw material powder in a silo, and then transfer the raw material powder to a designated position for granulation through conveying equipment such as a chain conveyor.

[0003] The top of the existing raw material silo for ceramsite sand is a cylindrical structure, and the bottom is a conical structure. The raw material powder in the silo falls into the chain conveyor through the bottom of the conical structure, thereby completing the transfer and storage of the raw material powder. However, the raw material powder will accumulate and even agglomerate at the bottom of the silo, which is not conducive to the transportation of the raw material powder. Content of the Utility Model

[0005] The utility model provides a raw material transfer and storage device for ceramsite sand, including a buffer silo. At least one feed inlet is opened on the buffer silo for receiving the raw material powder of the upper-level conveying equipment; the buffer silo includes a rectangular silo, a conical silo and a blanking silo arranged from top to bottom, and the rectangular silo, the conical silo and the blanking silo are communicated in sequence;

[0006] A dispersing assembly is arranged inside the blanking silo for dispersing the accumulated raw material powder in the blanking silo. An auxiliary blanking assembly is further arranged at the bottom of the blanking silo. The feed inlet of the auxiliary blanking assembly is communicated with the blanking silo, and a chain conveyor is arranged at the bottom of the discharge outlet of the auxiliary blanking assembly for sending the raw material powder to the next-level equipment.

[0008] One end of the rotating shaft is connected with the first motor through a first speed reducer, and the other end of the rotating shaft is rotatably connected with the outer wall of the blanking silo through a flange; a plurality of spike teeth are uniformly arranged on the surface of the rotating shaft.

[0009] Further, the auxiliary blanking assembly includes a second motor and a discharge chute;

An outlet is provided at one end of the discharge chute, and the position of the outlet is adapted to the position of the chain conveyor. An installation plate is provided at the end of the discharge chute away from the outlet and extends outward. The bottom of the second motor is connected to the installation plate;

[0011] A first spiral feeding rod is arranged inside the discharge chute, and the first spiral feeding rod is connected to the second motor through a second speed reducer.

[0012] In a further solution, a second spiral feeding rod is further arranged in the discharge chute. A first gear is arranged at the output end of the second speed reducer.
