TECHNICAL FIELD

[0001] The present application relates to a kind of inner and outer spiral spiral pipe water-cooled tuyere, can be widely used in cupola casting process. BACKGROUND

[0002] Cupola is the important equipment of melting cast iron in foundry production, after melting cast iron block into molten iron, pours into sand mould, and gets castings after opening sand box and cooling down.In the use process of cupola, in order to increase the combustion efficiency of cupola coke, air needs to be blown into the bottom of cupola, and the tuyere of blowing in air is usually inserted into the inside of furnace wall to ensure the smooth blowing in of air, but in actual use, high temperature produced by combustion can easily melt the tuyere, so how to blow in air under high temperature and ensure that the air inlet device is not melted is a difficult technical problem to solve.

[0003] At present, the existing water-cooled tuyere is usually single-cavity structure, most of the cooling water entering the tuyere directly returns to the water outlet, which leads to poor water circulation, short circuit of flow path, poor cooling effect, and water in pipeline is formed into steam by high heat, so the tuyere is often burned out, and replacement of tuyere often needs to stop work, which affects production. SUMMARY

[0004] The present application aims to provide a kind of inner and outer spiral spiral pipe water-cooled tuyere, which can avoid mixing of cold water and hot water, has smooth water flow, improved flow state, improved water flow efficiency, high precision, good performance of equipment, high thermal conductivity, good cooling performance, good corrosion resistance, stable structure performance, excellent mechanical properties and good welding performance.

[0005] To achieve the above purpose, the inner and outer spiral spiral pipe water-cooled tuyere of the present application comprises an outer ring formed by welding a left conical outer ring with inward flanging groove and a right outer ring together, a left inner ring welded with the inward flanging groove of the left conical outer ring, an inner ring formed by welding the left inner ring and a right inner ring together, an inner and outer spiral spiral pipe placed between the outer ring and the inner ring, a left flange connected with the right outer ring, the right inner ring and the inner and outer spiral spiral pipe, a right flange connected with the left flange through a connecting pin, a flange closed cylinder body sealingly connected with the left flange and the right flange, a water inlet pipe installed at the outer end of the flange closed cylinder body and the end of the right inner ring and provided with an arc-shaped groove at the water inlet pipe, a water outlet pipe installed at the outer end of the flange closed cylinder body and the end of the right inner ring and provided with an arc-shaped groove at the water outlet pipe, a water inlet and outlet pipe blocking plate located between the flange closed cylinder body and the right inner ring and installed on the flange closed cylinder body and the right inner ring, a left tuyere mounting ring installed on the left flange, and a right tuyere mounting ring installed on the right flange.

[0006] The inner and outer spiral spiral pipe water-cooled tuyere of the present application, the inner and outer spiral spiral pipe is a whole component, and the inner spiral and the outer spiral are located at the left part.

[0007] The present invention relates to an internal and external spiral tube water-cooled air outlet, wherein the flange-sealed cylinder is a cylindrical body.

[0008] The water-cooled air outlet of the present invention, which is an inner and outer spiral tube, is made of oxygen-free copper. The left conical outer ring, the left inner ring, and the inner and outer spiral tubes are all made of oxygen-free copper.

[0009] The water-cooled air outlet of the present invention, which is an inner and outer spiral tube, is made of carbon steel, wherein the right outer ring and the right inner ring are made of carbon steel.

[0010] The purpose of this invention's internal and external spiral tube water-cooled air inlet, with arc-shaped grooves at both the inlet and outlet pipes, is threefold: First, to control and regulate water flow. The arc-shaped grooves can adjust the water flow by changing its direction and speed, preventing erosion and maintaining waterway stability, thus ensuring smooth water flow. Second, to improve flow regime. The arc-shaped grooves can reduce the intensity and range of vortices within the grooves, thereby reducing the impact force of the water flow. Third, to improve water flow efficiency. By rationally designing the height and shape of the arc-shaped grooves, the water flow path can be optimized, improving the smoothness and efficiency of the water flow and reducing energy loss.

[0011] The working principle of this invention's internal and external spiral tube water-cooled air outlet is as follows: Cooling water enters through the inlet pipe, passes through the arc-shaped groove at the inlet pipe, and flows in a spiral path. First, it flows into the outer spiral of the internal and external spiral tubes, and then into the inner spiral. In this way, it flows along the spiral guide channel towards the outlet in a spiral trajectory, avoiding stagnation and dead zones, ensuring smooth water flow, increasing the circulation path, and improving the water cooling effect. Furthermore, the internal and external spiral tubes, the left conical outer ring, and the left inner ring of this invention are all made of oxygen-free copper, resulting in stable structural performance and good cooling performance. Finally, it flows out through the arc-shaped groove at the outlet pipe.

[0012] The water-cooled air inlet of the present invention, which is an internal and external spiral tube, has a water inlet and outlet pipe baffle plate. Its function is to clearly distinguish between the water inlet pipe and the water outlet pipe, and to prevent cold water from mixing with hot water.

[0013] The present invention relates to an internal and external spiral tube water-cooled air inlet. The arc-shaped groove at the water inlet and the arc-shaped groove at the water outlet are designed to ensure smooth water flow in and out.

[0014] This invention relates to an internally and externally spiral water-cooled air outlet. The internally and externally spiral tube is an integrally cast component with an inner and outer spiral. After casting, it is precision machined on a lathe, forming a single piece that ensures accurate machining of the inner and outer spirals. Therefore, the internally and externally spiral tube has high precision and provides excellent equipment performance.

[0015] This invention relates to an internal and external spiral water-cooled air inlet. The left conical outer ring, left inner ring, and internal and external spiral tubes are made of oxygen-free copper. The advantages of oxygen-free copper mainly include:

[0016] (1) High thermal conductivity: Oxygen-free copper has very high thermal conductivity. High thermal conductivity can help to transfer heat quickly and improve heat exchange efficiency. Therefore, it has good cooling performance.

[0017] (2) Good corrosion resistance: Since oxygen-free copper contains very few oxides, its corrosion resistance is relatively good, especially in environments with high humidity or corrosive water quality, and its structural performance is stable.

[0018] (3) Excellent mechanical properties: Oxygen-free copper has good mechanical properties, including high flexibility and ductility. This allows it to be stretched, bent or shaped during manufacturing without breaking.

[0019] (4) Good welding performance: Oxygen-free copper has excellent welding performance and is easy to connect with other metals.

[0020] Therefore, the present invention has high thermal conductivity, good cooling performance, good corrosion resistance, maintains stable structural performance, excellent mechanical properties, and good weldability.

[0021] In summary, the internal and external spiral tube water-cooled air outlet of this invention avoids the mixing of cold and hot water, ensures stable water flow, improves flow pattern, and increases water flow efficiency. The internal and external spiral tubes have high precision, good equipment performance, high thermal conductivity, good cooling performance, good corrosion resistance, stable structural performance, excellent mechanical properties, and good weldability.
