[0002] Calcium carbide slag is the waste residue mainly composed of calcium hydroxide after the hydrolysis of calcium carbide to obtain acetylene gas. Acetylene is one of the important raw materials in basic organic synthesis industries. The process of producing acetylene from calcium carbide by adding water is simple and mature, and currently accounts for a large proportion in my country. 1 ton of calcium carbide can produce more than 300 kg of acetylene gas, and at the same time generate 10 tons of industrial waste liquid with a solid content of about 12%, commonly known as calcium carbide slag slurry. Calcium carbide slag can be used to replace limestone in cement production, produce quicklime for use as a raw material for calcium carbide, produce chemical products, produce building materials, and for environmental remediation, etc. Summary of the Invention

[0003] To address the aforementioned problems, this invention discloses a production equipment for preparing active lime from carbide slag. This equipment utilizes a multi-segment structure to transport carbide slag, while simultaneously employing an integrated structure with movable joints to limit the amount of carbide slag being transported. The double-layer transport pipeline structure, with its inner liner dried and heated, provides stable transport conditions and prevents the carbide slag from gradually accumulating due to moisture during transport, thus affecting transport efficiency.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows:

The conveying port of the feeding box is connected to the conveying pipe. The tail output port of the conveying pipe is connected to the drying pipe through an active joint section. The tail end of the drying pipe is connected to a temporary storage chamber through a fixed joint section. The discharge port of the temporary storage chamber is equipped with a spiral discharge mechanism.

[0006] Furthermore, the outer shells of the active joint segment and the fixed joint segment are arc-shaped cylindrical end faces. The active joint segment extends inward along the openings on both sides with arc-shaped bowl-shaped ports. The middle sections of the two sets of arc-shaped bowl-shaped ports are connected in a smooth and continuous opening structure. The arc-shaped bowl-shaped ports are in active contact with the arc-shaped hemispherical ports of the material conveying pipe and the drying pipe.

[0007] Furthermore, the left inlet port of the fixed joint segment is an arc-shaped bowl-shaped port consistent with the active joint segment, and the right side of the arc-shaped bowl-shaped port extends and is connected to a smooth cylindrical material conveying port, which is connected to the temporary storage cavity.

[0008] Furthermore, the outer wall of the active joint segment is surrounded by a ring rib, and a swing docking end is fixedly installed on the bottom end face of the ring rib. The swing docking end is connected to the external swinging robotic arm via transmission.

[0009] Furthermore, the outer shell of the drying pipe is fitted with a flow valve, which is connected to an external boiler via a pipeline. A flow cavity is provided between the outer shell and the inner liner of the drying pipe, and the flow cavity is connected to the flow valve.

[0010] Furthermore, the spiral discharge mechanism includes a spiral discharge end, a friction belt drive motor, and a friction belt. The spiral discharge end is installed at the end of the material conveying port of the temporary storage cavity. The spiral discharge end has a spiral discharge blade built in, and the spiral discharge blade has a rotation drive segment along the middle section of the spiral discharge end. The rotation drive segment is in transmission contact with the friction belt drive motor through the friction belt.

[0011] The beneficial effects of this invention are as follows:

[0012] Compared with the prior art, the present invention adopts a production equipment for preparing active lime from carbide slag. It can transport carbide slag through a multi-segment structure, and at the same time, the transport feed amount of carbide slag can be limited by an integrated structure with movable joints. The double-layer transport pipeline structure with inner liner drying and heating provides stable transport conditions and avoids the carbide slag from gradually accumulating due to moisture during transport, which affects the transport efficiency.
