Vertical shaft furnace unit stationary furnace copper outlet throat structure

Abstract

This invention relates to a throat structure for a copper outlet in a vertical shaft furnace unit, comprising a furnace, a copper outlet on the furnace, a molten chamber within the furnace, and a throat connecting the molten chamber and the copper outlet. The throat includes an observation hole and a slag removal hole. The throat comprises a first section, a second section, and a third section. The observation hole and slag removal hole are located on the first section, the second section is located on the center extension line of the molten chamber, and the third section is located at the center of the molten chamber. This invention optimizes the throat structure, facilitating copper reflux and accelerating the reflux speed. The slag removal hole allows observation of the throat's internal condition and facilitates slag removal when the throat or observation hole is blocked. The increased diameter of the throat expands the observation range and cleaning angle of the observation hole, further enhancing observation and slag removal.

Description

Technical Field

[0001] This invention relates to a throat pipe structure for the copper outlet of a vertical furnace unit. Background Technology

[0002] Currently, the flow throat pipe at the copper outlet of the static furnace in the vertical shaft furnace unit has an unreasonable structural design, as shown in the attached... Figure 3 As shown, there is often a lot of cold copper accumulation, which makes it impossible to clean the internal copper slag. The copper slag floats in the upper part of the throat tube. The temperature of the molten copper in the molten cavity is blocked by the copper slag. The temperature in the throat tube area is lower than that in the molten cavity. During the converter, the molten copper is easily blocked by cold copper at the throat joint. The molten copper returns slowly, resulting in cooling blockage. Summary of the Invention

[0003] The technical problem to be solved by this invention is to provide a throat pipe structure for the copper outlet of the static furnace in a vertical shaft furnace unit, which avoids blockage of cold copper in the throat pipe, allows for fast copper molten return, and facilitates oxygen blowing maintenance.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a throat pipe structure for a copper outlet of a vertical shaft furnace unit, comprising a static furnace, a copper outlet disposed on the static furnace, a melting chamber disposed within the static furnace, and a throat pipe for connecting the melting chamber and the copper outlet, wherein the throat pipe is provided with an observation hole and a slag removal hole, the throat pipe comprising a first pipe section, a second pipe section and a third pipe section, wherein the observation hole and the slag removal hole are disposed on the first pipe section, the second pipe section is disposed on the center extension line of the melting chamber, and the third pipe section is disposed at the center position of the melting chamber.

[0005] Preferably, the first pipe section is a circular pipe with a diameter of R1.

[0006] Preferably, the second pipe segment is connected to the first pipe segment and the second pipe segment by a flared arc, and the diameter of the second pipe segment is R2.

[0007] Preferably, the third pipe section is an inclined irregularly shaped pipe with a larger top and a smaller bottom, and the diameter of the third pipe section is R3.

[0008] Preferably, R1 < R3 < R2.

[0009] Preferably, the slag removal hole is flared outwards.

[0010] Preferably, the slag removal hole is provided with a protective cover.

[0011] Preferably, an oxygen pipeline purging device can be removably installed on the slag removal hole.

[0012] In summary, the advantages of this invention are:

[0013] 1. The throat structure has been optimized to facilitate copper liquid reflux and accelerate the copper liquid reflux speed;

[0014] 2. A slag removal hole is provided so that when the throat or observation hole is blocked, the internal condition of the throat can be observed through the slag removal hole and the copper slag at the throat can be easily cleaned.

[0015] 3. An oxygen pipeline purging device can be removably installed on the slag removal hole, which facilitates purging when the throat is blocked, thus shortening the repair time;

[0016] 4. The diameter of the throat tube has been increased, expanding the observation range and cleaning angle of the observation hole, making it easier to observe and clean the slag through the slag removal hole. Attached Figure Description

[0022] To more clearly illustrate the overall concept of the present invention, the invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the terms "upper," "lower," "left," "right," "longitudinal," "lateral," "inner," "outer," "vertical," "horizontal," "top," and "bottom," etc., indicating orientation or positional relationships, are based solely on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0023] A structure for the copper outlet throat pipe of a vertical furnace unit, such as... Figure 1 and Figure 2 As shown, it includes a settling furnace 1, a copper outlet 2 disposed on the settling furnace 1, a melting chamber 3 disposed inside the settling furnace 1, and a throat pipe 4 for connecting the melting chamber 3 and the copper outlet 2. The throat pipe 4 is provided with an observation hole 5 and a slag removal hole 6. The throat pipe 4 includes a first pipe section 41, a second pipe section 42 and a third pipe section 43. The observation hole 5 and the slag removal hole 6 are disposed on the first pipe section 41, the second pipe section 42 is disposed on the center extension line of the melting chamber 3, and the third pipe section 43 is disposed at the center position of the melting chamber 3.

[0024] To facilitate observation, slag removal, and maintenance, the structure of the throat tube 4 is optimized. The first tube segment 41 is a circular tube with a diameter of R1. The second tube segment 42 connects the first tube segment 41 and the second tube segment 42 via an arc-shaped flared end, and the diameter of the second tube segment 42 is R2. The third tube segment 43 is an inclined irregularly shaped tube, wider at the top and narrower at the bottom, with a diameter of R3. R1 < R3 < R2. This modification to the internal structure of the throat tube 4, increasing its diameter, facilitates and accelerates the return of molten copper.

[0025] When the observation hole 5 is blocked, in order to facilitate both observation and slag removal, the slag removal hole 6 is set to be widened from the outside to the inside. At this time, the slag removal hole 6 can be used as the observation hole 5, increasing the diameter of the observation hole 5 and expanding the observation angle of the throat tube 4, and can also be used for slag removal, making it easier to remove the copper slag floating on the throat tube 4.

[0026] To prevent impurities from seeping in and to improve safety during use, a protective cover 7 is provided on the slag cleaning hole 6. The protective cover 7 can be opened for observation and slag cleaning, and then closed again when observation or slag cleaning is complete. The operation is simple and convenient.

[0027] To facilitate oxygen blowing maintenance of the throat 4, an oxygen pipeline purging device 8 can be removed from the slag removal hole 6.

[0028] In addition to the preferred embodiments described above, there are other embodiments of the present invention. Those skilled in the art can make various changes and modifications based on the present invention, and all such changes and modifications should fall within the scope defined by the appended claims, as long as they do not depart from the spirit of the present invention.
