Description

Technical Field

[0001] This utility model belongs to the field of electrode paste production technology, specifically a cooling device suitable for electrode paste forming equipment. Background Technology

[0002] Electrode paste is a key raw material for self-baking electrodes in submerged arc furnaces (such as ferroalloy furnaces and calcium carbide furnaces). During its production, the high-temperature molten electrode paste needs to undergo cooling and shaping processes. Effective and uniform cooling of the electrode paste is crucial during this process, as it not only affects its final physical properties (such as strength and conductivity) but also directly impacts the efficiency and quality of subsequent crushing and packaging. Simultaneously, the cooling, crushing, and transfer areas of the electrode paste generate a large amount of dust, which not only pollutes the working environment and endangers the health of operators but also poses certain safety risks.

[0003] Currently, water spraying (or water misting) is commonly used for cooling on electrode paste production lines. Typical spraying systems usually include a water supply pipeline and water outlets with a fixed diameter.

[0004] However, this fixed-caliber water spraying method has significant drawbacks and limitations:

[0005] The water spray volume is not adjustable: Because the diameter of the water outlet is fixed, the water spray volume (the amount of water output per unit time) remains constant under relatively stable water supply pressure. It cannot be flexibly adjusted according to real-time changes in the actual temperature of the electrode paste (such as temperature differences between different areas or temperature fluctuations between batches). Utility Model Content

[0006] This invention provides a cooling device suitable for electrode paste forming equipment, in order to overcome the deficiencies in the prior art.

[0007] This utility model is achieved through the following technical solution:

[0008] A cooling device suitable for electrode paste forming equipment includes a frame, an inner tube rotatably connected to the frame via bearings, an outer tube whose inner wall is in contact with the outer wall of the inner tube, and the rear ends of the outer tube and the inner tube are closed. The outer tube has several water spray holes along its length located on the same longitudinal line, and the inner tube has several water outlet holes along its length. The water outlet holes are evenly arranged in several rows along the circumference of the inner tube. The width of each row of water outlet holes increases counterclockwise along the inner tube. The diameter of the water spray holes is larger than the diameter of the water outlet holes. The outer end of the inner tube extends out of the outer tube and is connected to an external water source. The point where the inner tube extends out is rotatably connected to the outer tube via a sealed bearing. The outer end of the inner tube is driven by a drive mechanism to rotate along its axis.

[0009] In use, cooling water enters the inner tube. Because the inner tube is in close contact with the inner wall of the outer tube, water is prevented from flowing out of all the outlet holes of the inner tube. However, one outlet hole is opposite to the spray hole, allowing water to flow out from this outlet hole. When adjusting the water flow, the inner tube is rotated by the drive mechanism, so that another outlet hole is opposite to the spray hole. Since the width between the two adjacent outlet holes is different, the water flow is changed, thereby achieving a better temperature regulation effect.

[0010] Preferably, the drive mechanism includes a drive motor fixedly mounted on the frame, with a drive gear sleeved on the shaft of the drive motor, and a driven gear meshing with the drive gear sleeved on the outer end of the inner tube. When the drive motor is started, the rotation of the drive motor shaft drives the rotation of the drive gear, which in turn drives the rotation of the driven gear, which in turn drives the rotation of the inner tube.

[0011] Preferably, the water outlet is an elongated structure with its width increasing counterclockwise along the inner tube. The outer tube is rotated and stationary via a rotating mechanism. The rotation of the outer tube allows for changes in the water spray angle, thereby achieving better cooling as needed. The elongated shape of the water outlet ensures that water can still be dispensed even when the outer tube rotates at a certain angle.

[0012] Preferably, the rotating mechanism includes an arc-shaped plate fixedly mounted on a frame. The arc-shaped plate has an arc-shaped groove coaxial with the outer tube along its curvature. A rotating shaft is coaxially fixedly connected to the outer tube, and the rotating shaft is rotatably connected to the frame via bearings. One end of the rotating shaft is fixedly connected to a connecting rod, and the other end of the connecting rod is vertically connected to a lead screw inserted into the arc-shaped groove. Two compression nuts are threaded onto the lead screw, and the arc-shaped plate is located between the two compression nuts. The rotation of the outer tube drives the lead screw to rotate within the arc-shaped groove via the rotating shaft and connecting rod. Then, by rotating the compression nuts, the arc-shaped plate is compressed, thereby fixing the outer tube.

[0013] Preferably, the water spray hole is a flared mouth that is wider at the outside and narrower at the inside, and a wire mesh is fixedly connected near the outer end of the flared mouth. Through the flared mouth and the wire mesh, the water sprayed from the water spray hole can be further dispersed, thereby achieving a better cooling effect.

[0014] Preferably, the inner wall of the outer tube has an annular groove along its circumference, the outer ring of the sealing bearing is fixedly connected in the groove, and the inner wall of the inner ring of the sealing bearing is fitted and fixedly connected to the outer wall of the inner tube.

[0015] The beneficial effects of this utility model are as follows: the use of this application can change the amount of water sprayed by rotating the inner tube, thereby achieving better cooling. At the same time, the rotation of the outer tube can change the water spray position, thereby ensuring precise cooling and achieving better cooling. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] A cooling device suitable for electrode paste forming equipment, such as Figure 1 and Figure 2 As shown, the device includes a frame 1, an inner tube 3 rotatably connected to the frame 1 via bearings, an outer tube 2 whose inner wall is fitted and rotatably sealed to the outer wall of the inner tube 3, and the rear ends of the outer tube 2 and the inner tube 3 are closed. The outer tube 2 has several spray holes 4 along its length, located on the same longitudinal line. The inner tube 3 has several outlet holes 5 along its length, evenly arranged in several rows along the circumference of the inner tube 3. The width of each row of outlet holes 5 increases counterclockwise along the inner tube 3, and the diameter of the spray holes 4 is larger than the diameter of the outlet holes 5. The outer end of the inner tube 3 extends out of the outer tube 2 and is connected to an external water source. The point where the inner tube 3 extends out is rotatably connected to the outer tube 2 via a sealed bearing. Specifically, the inner wall of the outer tube 2 has an annular groove along its circumference, and the outer ring of the sealed bearing is fixedly connected within the groove, while the inner wall of the inner ring of the sealed bearing is fitted and fixedly connected to the outer wall of the inner tube 3. The outer end of the inner tube 3 is driven by a drive mechanism to rotate along its axis.

[0023] In use, cooling water enters the inner tube 3. Since the inner tube 3 is in close contact with the inner wall of the outer tube 2, water is prevented from flowing out of all the water outlets 5 of the inner tube 3. However, one water outlet 5 is opposite to the spray hole 4, so that water can flow out from this water outlet 5. When adjusting the water flow, the inner tube 3 is rotated by the drive mechanism, so that another water outlet 5 is opposite to the spray hole 4. Since the width between the two adjacent water outlets 5 is different, the water flow is changed, thereby achieving better temperature regulation.

[0024] The drive mechanism includes a drive motor 6 fixedly mounted on the frame 1. A drive gear 7 is sleeved on the shaft of the drive motor 6, and a driven gear 8 meshing with the drive gear 7 is sleeved on the outer end of the inner tube 3. When the drive motor 6 is started, the rotation of the drive motor 6 shaft drives the rotation of the drive gear 7, which in turn drives the rotation of the driven gear 8, which in turn drives the rotation of the inner tube 3.

[0025] The water outlet 5 has an elongated shape and its width increases counterclockwise along the inner tube 3. The outer tube 2 is driven to rotate and remain stationary by a rotating mechanism. The rotation of the outer tube 2 can change the water spray angle, thereby achieving better cooling as needed. The elongated shape of the water outlet 5 ensures that water can still be discharged even when the outer tube 2 rotates at a certain angle.

[0026] The rotating mechanism includes an arc-shaped plate 12 fixedly mounted on the frame 1. The arc-shaped plate 12 has an arc-shaped groove 9 coaxial with the outer tube 2 along its curvature. A rotating shaft is coaxially fixedly connected to the outer tube 2, and the rotating shaft is rotatably connected to the frame 1 via bearings. One end of the rotating shaft is fixedly connected to a connecting rod, and the other end of the connecting rod is vertically connected to a lead screw 10 inserted into the arc-shaped groove 9. Two compression nuts 11 are threaded onto the lead screw 10, and the arc-shaped plate 12 is located between the two compression nuts 11. The rotation of the outer tube 2 drives the lead screw 10 to rotate within the arc-shaped groove 9 via the rotating shaft and connecting rod. Then, by rotating the compression nuts 11, the arc-shaped plate 12 is compressed, thereby fixing the outer tube 2.

[0027] The water spray hole 4 is a flared mouth that is wider on the outside and narrower on the inside, and a wire mesh is fixedly connected near the outer end of the flared mouth. Through the flared mouth and the wire mesh, the water sprayed from the water spray hole 4 can be further dispersed, so as to achieve better cooling.

[0028] The use of this application allows for changes in the water spray volume through the rotation of the inner tube 3, thereby achieving better cooling. At the same time, the rotation of the outer tube 2 allows for changes in the water spray position, thereby ensuring precise cooling and achieving better cooling.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
