Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbide production and processing, in particular to an electrode paste adding hopper. Background Art

[0002] The calcium carbide furnace technology currently used is transformed from the ore-fired furnace designed by Aiken in Germany. Its production process mainly uses a large amount of electrical energy to convert into thermal energy to achieve high-temperature chemical reactions and smelting. A large amount of thermal energy comes from the electrode column, and the main component of the electrode column is electrode paste. When manufacturing the electrode column, the block electrode paste needs to be loaded into the electrode cylinder and gradually enter the furnace body with the electrode cylinder. As the temperature rises, it is automatically baked into an electrode with extremely high hardness. The traditional electrode paste installation process is all completed by manpower, and the block electrode paste is completed through the steps of "screening → loading → hoisting".

[0003] The Chinese patent disclosed patent number CN218443333U is a paste hopper for a calcium carbide furnace. When the paste hopper body and the conical plug are used to carry the electrode paste, it is inconvenient to screen the electrode paste, and the electrode paste needs to be manually screened and added to the paste hopper body; however, the baking of electrode columns in a submerged arc furnace has strict requirements on the particle size of the electrode paste, and the industry standard generally requires a particle size of 50-100mm. However, small particles of electrode paste will be produced during the production, transportation and on-site transfer of the electrode paste due to collision, so it is necessary to manually screen the electrode paste with qualified particle size and load it into the hopper for use, which greatly increases the labor intensity of the workers and wastes a lot of time. Utility Model Content

[0004] The utility model aims to provide an electrode paste adding hopper, which is used to solve the problem that the existing electrode paste adding hopper needs to manually screen the electrode paste before adding, which increases the labor intensity of workers.

[0006] Furthermore, the screening and paste adding hopper body includes a first connecting ring, a second connecting ring, a discharge conical ring, a plurality of vertical fixed rods arranged in a circular array on the first connecting ring and the second connecting ring, and a plurality of inclined fixed rods arranged in a conical array between the second connecting ring and the discharge conical ring.

[0007] Furthermore, the screening cone plug includes a blocking cone ring with one end extending out from below the discharge cone ring, and a plurality of inclined columns connected between the blocking cone ring and the sliding rod and arranged in a cone array.

[0008] Furthermore, the bottom area of ​​the blocking conical ring is larger than the bottom area of ​​the discharging conical ring.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] The utility model has the following beneficial effects:

[0011] When it is necessary to load electrode paste, it is only necessary to lift the ton bag of electrode paste to the top of the electrode paste adding hopper by the overhead crane and load it into the screening and adding hopper body. The electrode paste is screened by the screening and adding hopper body and the screening cone plug. The electrode paste that has passed the screening is adjusted to the feeding port at the top of the electrode cylinder by the overhead crane. The contact surface of the lower cone part of the screening and adding hopper body is evenly supported on several ribs inside the electrode cylinder. As the hook of the overhead crane continues to be lowered, the screening cone plug continues to The electrode paste adding hopper falls, and the discharge conical ring outlet of the screening and paste adding hopper body opens, and the electrode paste is evenly discharged into the electrode cylinder along the side of the screening conical plug. After unloading, the screening conical plug is lifted by the overhead crane hook, and the screening conical plug plugs the discharge conical ring outlet of the screening and paste adding hopper body, and then the screening and paste adding hopper body is lifted to load the material; thus, the electrode paste adding hopper solves the problem of manual screening of the electrode paste before installation, and avoids the problems of time-consuming manual screening, heavy labor, and time-consuming hopper loading process.
