Description

Technical Field

[0001] This utility model relates to the field of submerged arc furnace technology, specifically to a high-efficiency water manifold for submerged arc furnaces. Background Technology

[0002] In the submerged arc furnace industry, the conductive device that connects the medium / low voltage compensator to the inner copper tube connector is called a busbar. The development history of busbars can be traced back to their evolution in various industrial applications.

[0003] Early busbars were relatively simple, mainly used to distribute electrical energy to the copper tube joints inside the furnace via medium and low voltage compensating conductors. With the continuous advancement of industrial technology, especially in applications such as submerged arc furnaces, higher requirements have been placed on the performance and function of busbars. Traditional submerged arc furnace busbars suffer from many problems, such as insufficient conductive cross-section, poor cooling effect, inconvenient installation and maintenance, and poor connection stability. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency water manifold for submerged arc furnaces to solve the problems of poor cooling effect and inconvenient installation and maintenance in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency water manifold for a submerged arc furnace, comprising a manifold body, clamping members fixedly installed on both sides of the manifold body for clamping conductive copper pipes, and a cooling circulation structure provided on the manifold body. The top of the manifold body is fixedly installed on the lower holding cylinder of the submerged arc furnace through an insulating connecting bracket. The manifold body includes a horizontal part and a vertical part connected thereto, and the whole is in a T-shaped structure. The cooling circulation structure includes a copper pipe joint for connecting a water-cooled cable and a circulating water channel provided inside the manifold body. The copper pipe joint is fixedly installed on the surface of the horizontal part and communicates with the circulating water channel.

[0006] Furthermore, the clamping component includes clamping blocks, and semi-cylindrical slots are equally spaced on the left and right sides of the vertical part. The semi-cylindrical slots on the left and right sides are staggered. Each semi-cylindrical slot is fixedly installed with a clamping block by bolts. A semi-cylindrical slot is provided on the clamping block. The semi-cylindrical slots and semi-cylindrical slots are fitted together to form a cylindrical groove for clamping the conductive copper tube.

[0007] Furthermore, the top end of the insulating connection bracket is fixedly installed on the lower holding cylinder of the electric arc furnace by bolts, and the bottom end of the insulating connection bracket is fixedly installed on the top end of the busbar body by bolts.

[0008] This utility model has the following beneficial effects:

[0009] This invention provides a high-efficiency water manifold for a submerged arc furnace. Cooling water can flow smoothly in the circulating water channel, promptly removing the heat generated by the manifold, thereby ensuring that the manifold always operates in a low temperature environment. Compared with traditional manifolds, this invention has better cooling effect, stronger current carrying capacity, higher mechanical strength, is easier to install and maintain, has a long service life, and low maintenance cost.

[0014] like Figures 1 to 3 As shown, a high-efficiency water-passing manifold for a submerged arc furnace includes a manifold body 1, clamping components fixedly installed on both sides of the manifold body 1 for holding conductive copper pipes, and a cooling circulation structure provided on the manifold body 1. The top of the manifold body 1 is fixedly installed on the lower holding cylinder of the submerged arc furnace through an insulating connecting bracket 2. The manifold body 1 includes a horizontal part and a vertical part connected thereto, and the whole is in a T-shaped structure. The cooling circulation structure includes copper pipe joints 3 for connecting water-cooled cables and a circulation water channel 4 provided inside the manifold body 1. There are four copper pipe joints 3, which are fixedly installed on the surface of the horizontal part and connected to the circulation water channel 4. The water-passing manifold is made of TU1 oxygen-free electrolytic copper, with a maximum conductivity density of 4 amperes / square millimeter. It has high conductivity and oxygen-free copper does not exhibit hydrogen embrittlement. Compared with traditional manifolds, it can maintain its structural temperature ≤32℃ at an ambient temperature of 100℃ to ensure excellent conductivity and mechanical strength.

[0015] The four copper pipe joints 3 are arranged in a parallelogram. Cooling water enters from the two lower copper pipe joints 3, flows through the internal circulation channel 4, and then flows out from the two upper copper pipe joints 3, forming a complete cooling cycle.

[0016] The clamping component includes a clamping block 5. Semi-cylindrical slots are equally spaced on both sides of the vertical section. These semi-cylindrical slots are staggered. Each semi-cylindrical slot is fixed to a clamping block 5 by bolts. A second semi-cylindrical slot is formed on the clamping block 5. When the first and second semi-cylindrical slots fit together, they form a cylindrical groove for holding conductive copper tubes. This increases the conductive cross-sectional area, reduces reactive power loss due to heat generation, and facilitates installation and maintenance. Additionally, a clamping warning gap is provided on the upper side of the clamping point between the clamping block 5 and the busbar body 1, providing space for clamping the copper tubes inside the furnace and preventing current arcing.

[0017] The top end of the insulating connection bracket 2 is fixedly installed on the lower holding cylinder of the electric arc furnace by bolts, and the bottom end of the insulating connection bracket 2 is fixedly installed on the top end of the busbar body 1 by bolts.

[0018] The specific operation process of this utility model is as follows:

[0019] An insulating connection bracket 2 is securely installed on the lower holding cylinder of the electric arc furnace by bolts. The busbar body 1 is bolted to the bottom of the insulating connection bracket 2. The short conductive copper pipe is connected to the water-cooled cable. The water-cooled cable is connected to the copper pipe inside the furnace. The copper pipe inside the furnace is squeezed and clamped between the clamp block 5 and the semi-cylindrical slots on both sides of the bottom of the busbar body 1. The two cooperate with each other to achieve a stable and tight connection. At the same time, the low-voltage compensation copper pipe is connected to the low-voltage compensation water-cooled cable. The low-voltage compensation water-cooled cable is connected to the copper pipe joint 3, which plays the role of conducting electricity and water.

[0020] During the operation of the submerged arc furnace, cooling water flows smoothly through the circulating water channel, promptly carrying away the heat generated by the manifold during operation and ensuring stable operation of the manifold in a low-temperature environment; the water-passing manifold distributes the low-voltage compensated electrical energy to the copper tubes inside the furnace, ensuring the normal operation of the submerged arc furnace.
