Description

Technical Field

[0001] The utility model belongs to the technical field of electrode paste cooling, and in particular relates to an electrode paste cooling mechanism. Background Art

[0002] Electrode paste is a conductive material used in electric furnaces such as ferroalloy furnaces and calcium carbide furnaces. Electrode paste is also called self-baking electrode. It relies on the heat in the submerged arc furnace to complete the baking. Therefore, the key to the use of electrode paste is to match the electrode consumption rate with the baking rate. As the technology of submerged arc furnaces develops gradually towards large-scale and closed directions, the electrode has reduced the amount of conductive heat and radiant heat obtained by the open furnace in the past to only conductive heat during the baking process. Therefore, the heat obtained by the electrode from the furnace is greatly reduced, which requires improving the sintering performance of the electrode paste to make up for this deficiency.

[0003] Chinese patent application No. 2020228447708 discloses a cooling water cooling device for electrode paste forming, including a sedimentation tank, a cooling cylinder, a crushed material receiving ring, a screen and an annular spray pipe; a mud discharge pipe is connected to the bottom of the sedimentation tank, a drain pipe is connected to the middle of the sedimentation tank, and a mud discharge valve is installed on the mud discharge pipe; the crushed material receiving ring is horizontally fixed to the upper edge of the sedimentation tank, a conical support frame is fixed on the inner side of the crushed material receiving ring, and a screen is fixed above the support frame; a cooling cylinder is fixed by a support rod directly above the sedimentation tank. By opening a hole in the annular spray pipe, the cooling water is fully in contact with the air during the falling process, reducing the cooling water temperature and ensuring normal use in summer; and the water sprayed from the annular spray pipe falls on the screen, separating the electrode paste particles mixed in the cooling water, falling on the crushed material receiving ring, and recycling, realizing the recycling of cooling water, reducing the discharge of cooling water, and reducing water consumption.

[0004] The above-mentioned patent cannot process the cooling water after use for recycling, resulting in a waste of water resources. At the same time, the original device filters the electrode paste and cooling water through a screen. When the screen filters the electrode paste and cooling water, water stains are easily discharged through the slag discharge port, and the screen has a poor filtering effect on the electrode paste and cooling water.
