Description

Technical Field

[0001] This utility model relates to the field of nickel-based alloy preparation technology, and in particular to a circulating water cooling system used in the preparation process of nickel-based alloys. Background Technology

[0002] Nickel-based alloys are a class of alloys that possess high strength and certain resistance to oxidation and corrosion at high temperatures of 650–1000℃. They are further subdivided according to their main properties into nickel-based heat-resistant alloys, nickel-based corrosion-resistant alloys, nickel-based wear-resistant alloys, nickel-based precision alloys, and nickel-based shape memory alloys. High-temperature alloys are classified according to their matrix into iron-based high-temperature alloys, nickel-based high-temperature alloys, and cobalt-based high-temperature alloys. Nickel-based high-temperature alloys are often simply referred to as nickel-based alloys, and their manufacturing process requires the use of a circulating water cooling system.

[0003] In the preparation of nickel-based alloys, the circulating water cooling system needs to continuously cool key components such as high-temperature reaction equipment and smelting devices, causing the circulating water to frequently undergo alternating cycles of heating and cooling. During this process, dissolved minerals in the water are prone to precipitate and form scale, and impurities such as metal fragments generated by equipment wear may also be mixed in. If impurities accumulate, they can cause pipe blockage and reduced heat exchange efficiency, thereby affecting the preparation quality and production continuity of nickel-based alloys. In existing technologies, fixed filters are usually installed at the inlet or outlet of the circulating water cooling system to intercept impurities. However, the interception channel of this structure is fixed, and impurities easily adhere to the filter screen and form blockages. Frequent disassembly and cleaning by operators are required, increasing manual labor intensity and affecting the efficiency of circulating water cooling and the production progress of nickel-based alloys.

[0004] Therefore, it is necessary to propose a circulating water cooling system for nickel-based alloy preparation processes to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a circulating water cooling system for nickel-based alloy preparation processes, in order to solve the problem that in the prior art, fixed filters are usually installed at the inlet or outlet of the circulating water cooling system to intercept impurities. However, the interception channel of this structure is fixed, and impurities are easily attached to the filter screen to form a blockage. This requires operators to frequently disassemble and clean the filter screen, which increases the intensity of manual labor and affects the efficiency of circulating water cooling and the production progress of nickel-based alloys.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a circulating water cooling system for a nickel-based alloy preparation process, comprising a filtration mechanism, a water cooling mechanism, and a conveying mechanism, wherein the conveying mechanism is located between the filtration mechanism and the water cooling mechanism; The filtration mechanism includes a filter funnel located inside the tank. A rotating column is installed above the filter bucket. The top of the rotating column is integrally formed with a cone for receiving the incoming water flow, with the tip of the cone pointing upwards. Blades are installed on the side wall of the cone. During filtration, the tip of the filter funnel faces upward and surrounds the outside of the rotating column. The rotating column and the cone rotate on their own axis, while the tip of the filter funnel moves back and forth along the height of the rotating column. When cleaning, the tip of the filter funnel should face downwards to allow impurities to slide off.

[0007] Preferably, the filter bucket includes a thin section, an elastic section, and a coarse section, with the elastic section fixed between the thin section and the coarse section, and the coarse section fixed on the inner wall of the tank.

[0008] Preferably, an inner ring is fixedly connected to the end of the thin segment away from the elastic segment, and the inner ring is slidably disposed on the rotating column.

[0009] Preferably, the bottom of the tank is provided with a through groove, a connecting rod is slidably arranged inside the through groove, the top end of the connecting rod is fixedly connected to the inner ring, and an electric push rod is provided on the outside of the tank to drive the connecting rod to move up and down.

[0010] Preferably, a support plate is fixedly installed on the inner wall of the tank, and a circular sleeve is fixedly connected to the support plate, with the rotating column rotatably mounted on the circular sleeve.

[0011] Preferably, the tank is equipped with a water inlet pipe, and the water outlet end of the water inlet pipe is vertically downward and facing the cone head, and the bottom end of the tank is connected to a water outlet pipe.

[0012] Preferably, the bottom of the tank is provided with a bottom groove, and a cover plate fits inside the bottom groove.

[0013] The technical effects and advantages of this utility model are as follows: 1. This utility model, by setting up a filter bucket, cone head and other structures, can flexibly realize the filter bucket tip facing up or down, quickly switch between filtration and cleaning, and achieve the effect of impurity filtration and automatic collection, reducing the frequency of manual cleaning and improving the efficiency of the circulating water cooling system. 2. The filter is equipped with a cone and blade structure, which rotates by the impact of water flow. The centrifugal force generated during the rotation helps the water flow to spread outward, so that the water flow can flow evenly across the filter surface of the filter bucket and improve the filtration efficiency. 3. Because the filter bucket is bucket-shaped, the water flow will carry the impurities on the filter bucket downwards and concentrate them at the connection between the coarse section and the inner wall of the tank, thus completing the automatic collection of impurities. 4. In this utility model, the self-rotation of the cone head can disperse the vertically falling water flow, reduce the impact force of the water flow on the filter bucket, thereby reducing the scouring and wear of the filter bucket and extending its service life. 5. The connecting rod drives the inner ring to reciprocate along the height of the rotating column, which in turn drives the tip of the filter bucket to reciprocate synchronously, creating a shaking effect in the filter bucket and accelerating the sliding of impurities down the filter bucket. 6. With the filter bucket tip pointing downwards, impurities attached to the filter bucket will slide down towards the tip of the filter bucket under the action of gravity, and then slide out through the inner ring and bottom groove. At the same time, shaking the filter bucket will accelerate the sliding of impurities. Attached Figure Description

[0021] This utility model provides, for example Figures 1-6 The circulating water cooling system used in a nickel-based alloy preparation process shown includes a filtration mechanism 1, a water cooling mechanism 2, and a conveying mechanism 3. The conveying mechanism 3 is located between the filtration mechanism 1 and the water cooling mechanism 2. The conveying mechanism 3 includes a corrosion-resistant centrifugal pump, matching pipeline components, and other structures, which are used to stably convey the circulating water filtered by the filtration mechanism 1 to the water cooling mechanism 2. The water cooling mechanism 2 includes a shell-and-tube heat exchanger, a cooling fan assembly, a temperature sensor, and a flow regulating valve, which are used to cool the circulating water and then return it to key components such as high-temperature reaction equipment and smelting devices.

[0022] The filtration mechanism 1 includes a tank 101, on which an inlet pipe 102 is installed for inputting heated water into the tank 101. The bottom end of the tank 101 is connected to an outlet pipe 103, which is connected to the conveying mechanism 3.

[0023] The bottom end of the tank body 101 is provided with a bottom groove 104, and a cover plate 105 is threadedly connected inside the bottom groove 104.

[0024] The tank body 101 is equipped with a filter hopper 4, which includes a thin section 401, an elastic section 402 and a coarse section 403. The elastic section 402 is fixed between the thin section 401 and the coarse section 403. The outer ring edge of the coarse section 403 is fixed to the inner wall of the tank body 101, and a sealing gasket is provided between the coarse section 403 and the inner wall of the tank body 101 to ensure the sealing of the connection.

[0025] Both the fine section 401 and the coarse section 403 are made of stainless steel filter screens with a mesh size of 80-120 mesh, which can effectively intercept impurity particles in the water. The elastic section 402 is made of high-temperature resistant rubber material and has a certain degree of elasticity. When the tip of the filter bucket 4 moves up and down with the inner ring 5, the elastic section 402 will stretch and deform accordingly, causing the filter surface of the filter bucket 4 to vibrate slightly, preventing impurities from adhering and accumulating on the filter screen, and improving the continuity of filtration. The water flows from top to bottom along the inclined surface of the filter bucket 4 to complete the filtration process. The clean water filtered by the filter bucket 4 is collected at the bottom of the tank 101 and transported to the conveying mechanism 3 through the water outlet pipe 103.

[0026] A rotating column 8 is installed above the filter hopper 4. The top of the rotating column 8 is integrally formed with a cone head 9, and the outlet end of the water inlet pipe 102 is vertically downward and facing the cone head 9. The cone angle of the cone head 9 is 60-90°, and the tip of the cone head 9 is upward. 3-4 blades 10 are evenly installed on the side wall of the cone head 9 along the circumference. A support plate 6 is fixedly installed on the inner wall of the tank body 101 by welding. A circular sleeve 7 is fixedly connected to the support plate 6 by bolts. The rotating column 8 is rotatably mounted on the circular sleeve 7. The circular sleeve 7 can provide stable support for the rotating column 8. At the same time, a ball bearing structure is provided between the rotating column 8 and the circular sleeve 7 to reduce the frictional resistance when the rotating column 8 rotates and to ensure the smoothness of the rotating column 8 during rotation.

[0027] An inner ring 5 is fixedly connected to the end of the thin segment 401 away from the elastic segment 402. The inner ring 5 is slidably mounted on the rotating column 8. A wear-resistant bushing is provided between the inner ring 5 and the rotating column 8 to reduce wear during relative sliding. A through groove 1101 is opened at the bottom of the tank body 101. A connecting rod 11 is slidably mounted inside the through groove 1101. A sealing sleeve is provided on the inner wall of the through groove 1101 to prevent water leakage. The top end of the connecting rod 11 is fixedly connected to the inner ring 5. An electric push rod 12 is provided on the outside of the tank body 101 to drive the connecting rod 11 to move up and down. The fixed end of the electric push rod 12 is mounted on the support of the tank body 101. The connecting rod 11 is fixedly connected to the telescopic end of the electric push rod 12. The electric push rod 12 drives the connecting rod 11 and the inner ring 5 to move up and down, thereby making the tip of the filter hopper 4 face up or down.

[0028] During filtration, the tip of filter funnel 4 should face upwards and surround the outside of rotating column 8 (see reference). Figure 2 The inner ring 5 and the rotating column 8 are in sliding fit. The circulating water is transported to the tank 101 through the water inlet pipe 102. Since the water outlet of the water inlet pipe 102 is vertically downward and facing the cone 9, when the water flow impacts the blades 10 on the side wall of the cone 9, it will generate a rotational torque along the axis of the rotating column 8, which will drive the rotating column 8 and the cone 9 to rotate in the sleeve 7. The centrifugal force generated during the rotation can help the water flow to spread outward, so that the water flow can flow evenly through the filter surface of the filter bucket 4 and improve the filtration efficiency. At the same time, since the filter bucket 4 is bucket-shaped, the water flow will carry the impurities on the filter bucket 4 to slide down and fall to the connection between the coarse section 403 and the inner wall of the tank 101, completing the automatic collection of impurities and reducing the frequency of manual cleaning.

[0029] Compared to the existing technology where water flows vertically and directly acts on the filter element, the cone head 9 in this invention can disperse the vertically falling water flow, reduce the impact force of the water flow on the filter bucket 4, thereby reducing the scouring and wear of the filter bucket 4 and extending its service life.

[0030] At the same time, the electric push rod 12 outside the tank 101 is activated, which drives the inner ring 5 to reciprocate along the height direction of the rotating column 8 through the connecting rod 11, thereby driving the tip of the filter hopper 4 to reciprocate synchronously. The filter hopper 4 produces a shaking effect, which accelerates the impurities to slide down the filter hopper 4, ensuring that the fine section 401 always maintains a good filtration efficiency.

[0031] During cleaning, close the inlet valve of the inlet pipe 102, remove the cover plate 105, and the electric push rod 12 drives the connecting rod 11 to move the inner ring 5 downward. At this time, the thin section 401 of the filter hopper 4 flips downward under the action of gravity and the tension of the inner ring 5, and the elastic section 402 undergoes reverse deformation, so that the tip of the filter hopper 4 faces downward. The impurities attached to the filter hopper 4 slide down to the tip of the filter hopper 4 under the action of gravity and slide out through the inner ring 5 and the bottom groove 104. At the same time, the operator assists in cleaning and can shake the filter hopper 4 several times to accelerate the sliding of impurities. The entire cleaning process does not require disassembling the filter screen or stopping the machine for a long time, which greatly shortens the cleaning time and reduces the intensity of manual labor.

[0032] In addition, during a longer service life (such as 1 year), operators should remove the filter hopper 4 and other structures for inspection and replacement.

[0033] After cleaning, the electric push rod 12 drives the inner ring 5 to reset upwards, and the filter hopper 4 returns to the filtration state with its tip facing upwards.

[0034] In summary, by setting up structures such as the filter bucket 4 and the cone head 9, this utility model can flexibly achieve the upward or downward orientation of the tip of the filter bucket 4, quickly switch between filtration and cleaning, and achieve the effect of impurity filtration and automatic collection, reducing the frequency of manual cleaning and improving the efficiency of the circulating water cooling system.
