Description
Technical Field
The utility model relates to the technical field of copper smelting, in particular to a sampling device of a rotary anode furnace.
Background
The rotary anode furnace is the main metallurgical furnace kiln equipment of the prior copper smelting and fire refining process, and the crude copper is oxidized and reduced in the anode furnace to produce the product anode copper. The traditional sampling method for final sample application of anode furnace oxidation and final sample application of reduction at present is to sample through an anode furnace mouth, and the sampling of the furnace mouth has the following problems: every sampling is carried out by shaking the furnace mouth from a converting position (generally 0 ℃) to a safety position (generally 40-60 ℃), so that the continuity of the oxidation and reduction operation process of the furnace body is seriously influenced; the safety belt is needed to be worn by the staff in front of the furnace for sampling from the furnace mouth, and potential safety hazards such as high-temperature burning, high falling and the like exist in the sampling process; sampling or measuring temperature from a furnace mouth for 5-10min each time, so that the temperature of the melt in the furnace is reduced by at least 10 ℃; the furnace mouth is frequently opened and closed by furnace mouth sampling, so that the loss rate of facilities such as furnace mouth cylinder sealing and the like is accelerated.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide the sampling device of the rotary anode furnace, which has the advantages of simple structure, low cost, good effect and safe operation process.
The aim of the utility model is realized by the following technical scheme:
a sampling device of a rotary anode furnace, which is characterized in that: including two horn mouth form sampling hole bricks, it has the toper sampling hole to open on the sampling hole brick, and the sampling hole brick sets up in rotary anode furnace side, and the sampling hole communicates with rotary anode furnace inside, and the large aperture of sampling hole is inside towards rotary anode furnace.
Preferably, the sampling hole brick is an electric melting and combining magnesia chrome brick.
Preferably, the sampling hole brick is a half-recombined magnesia chrome brick.
The beneficial effects of the utility model are as follows:
(1) Through the sampling of end wall sampling port, the anodic oxidation second stage, reduction stage operation process are more continuous, keeps warm, reduction efficiency promotes, and natural gas cost obtains the saving.
(2) The sampling process is safer than furnace mouth sampling.
(3) The total opening and closing times of the furnace mouth cover are reduced by about 1/3 compared with the furnace mouth sampling, the sealing loss rate of the furnace mouth cylinder is reduced, the service life is prolonged by 30% compared with that before transformation, and the spare part cost of anode furnace equipment is saved.
(4) The large aperture of the sampling hole faces the inside of the rotary anode furnace hearth, so that the sampling spoon can conveniently extend into the sampling hole in an inclined and downward manner to sample.

Detailed Description
The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present utility model, based on the embodiments of the present utility model.
Referring to fig. 1-3, the present utility model provides a technical solution:
the utility model provides a sampling device of rotary anode furnace, includes two horn mouth form sampling hole bricks 2, and specific size optional is 360 x 350 x 345, open on the sampling hole brick 2 has toper sampling hole 3 (aperture 288-226), and the size guarantees that the sampling spoon can stretch into, and the staff can carry out the sampling operation in front of the furnace. The sampling hole brick 2 is an electrofusion recombined magnesia chrome brick or a semi-recombined magnesia chrome brick. The sampling hole bricks 2 are arranged on the side edges of the rotary anode furnace 1, and the sampling holes 3 are communicated with the inside of the hearth of the rotary anode furnace 1. Specifically, the sampling hole brick 2 is built at the position of the observation port of the end wall of the side, containing the burner brick 4, of the rotary anode furnace 1 (see fig. 1), and when the rotary anode furnace is built, the large aperture of the sampling hole 3 faces the inside of the hearth of the rotary anode furnace 1, so that a sampling spoon can conveniently extend downwards into the sampling hole 3 in an inclined manner to sample. When not sampling, set up the apron in sample hole 3 department, block up sample hole 3, guarantee safety, maintain the heat in the stove.
The foregoing is merely a preferred embodiment of the utility model, and it is to be understood that the utility model is not limited to the form disclosed herein but is not to be construed as excluding other embodiments, but is capable of numerous other combinations, modifications and environments and is capable of modifications within the scope of the inventive concept, either as taught or as a matter of routine skill or knowledge in the relevant art.
