Description

Technical Field

[0001] This utility model relates to the field of vanadium ore processing technology, and in particular to a cableway-traction type vanadium baking kiln. Background Technology

[0002] Ammonium metavanadate is dehydrated and deammonied upon heating to form vanadium pentoxide. The heating process is generally completed in a tunnel kiln, where the loaded crucible moves inside the kiln. A drive mechanism is installed on the track at the bottom of the tunnel kiln to allow the crucible to feed in from the kiln inlet and discharge from the kiln outlet. In this method, the bottom of the kiln needs to be cleaned regularly, and the track also needs to be cleaned periodically. In addition, the crucible is basically in a "grounded" state, and the bottom of the crucible cannot be effectively heated, resulting in only the upper and side surfaces of the crucible being heated, which affects the rapid and uniform heating of the crucible. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention proposes a vanadium baking kiln that can increase the heating area of ​​the crucible and eliminates the need for frequent cleaning of the kiln bottom.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a cable-driven vanadium baking kiln, characterized in that it includes two rotating wheels, two parallel traction cables, a furnace body, and several crucibles. The two rotating wheels are located at both ends of the furnace body, and one straight section of the traction cable passes through the furnace body. The outer wall of the crucible has two parallel slots, and the crucible can be mounted on the traction cables by being inserted into the two slots by the two traction cables respectively.

[0005] Furthermore, the slot has a notch in the middle, and a limiting block corresponding to the notch is fixedly installed on the traction cable.

[0006] This type of vanadium baking kiln allows the crucible to be suspended on the traction cable, meaning the crucible does not contact the bottom of the furnace body. There is no need for a ground track to guide the movement of the crucible within the furnace body. Instead, the crucible moves smoothly and slowly within the furnace body using the cyclic traction of the traction cable. This allows the entire bottom of the crucible to be directly heated, increasing the heating area and improving heating efficiency and uniformity.

[0007] The traction cables have straight sections on both the inlet and outlet sides of the furnace body for installing and removing crucibles. When installing the crucible, it is directly inserted from top to bottom onto the two traction cables. The positioning of the slots and the traction cables, along with the notches and limiting blocks, prevents the crucible from sliding along the cables. After the vanadium balls are inserted, their own weight maintains the reliable connection between the traction cables and the crucible, preventing tipping or detachment during slow and stable movement. For discharge, the crucible is simply removed upwards. A cooling section is also provided after the outlet to cool it to a safe temperature before removing the crucible and the vanadium balls inside.

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2 and Figure 3 The vanadium baking kiln shown includes two rotating wheels 1, two parallel traction cables 2, a furnace body 3, and several crucibles. The two rotating wheels 1 are located at both ends of the furnace body 3. One straight section of the traction cable 2 passes through the furnace body 3. The outer wall of the crucible has two parallel slots 4. The crucible can be mounted on the traction cable 2 by being inserted into the two slots 4 by the two traction cables 2 respectively. The slot 4 has a notch 5 in the middle. A limiting block 6 corresponding to the notch 5 is fixedly installed on the traction cable 2.

[0014] This type of vanadium baking kiln allows the crucible to be suspended on the traction cable 2, meaning the crucible does not contact the bottom of the furnace body 3. There is no need for a ground track to guide the movement of the crucible within the furnace body 3. Instead, the crucible moves smoothly and slowly within the furnace body 3 by the cyclic traction of the traction cable 2, allowing the entire bottom of the crucible to be directly heated, increasing the heating area, and improving heating efficiency and uniformity.

[0015] The traction cable 2 has a straight section on both the inlet and outlet sides of the furnace body 3 for installing and removing the crucible. When installing the crucible, it is directly inserted from top to bottom onto the two traction cables 2. The positioning of the groove 4 and the traction cable 2, and the limiting block 6 of the notch 5, prevent the crucible from sliding along the cableway. After the vanadium ball is inserted, its own weight maintains the reliable connection between the traction cable 2 and the crucible, preventing tipping or detachment during slow and stable movement. For discharge, it is simply removed upwards. A cooling section is also provided after the outlet to cool the material to a safe temperature before removing the crucible and the vanadium ball inside. Even if slag falls inside the furnace body 3, no special cleaning is required, allowing the furnace body 3 to remain operational without interruption.

[0016] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
