Description

Technical Field

[0001] The utility model relates to the field of cooling devices for anode mud materials, in particular to a cooling coil of a slow cooling tank. Background Art

[0002] The function of the slow cooling tank in the current copper anode mud leaching system is to quickly cool the high-temperature anode mud slurry to below 80°C, facilitating the subsequent solid-liquid separation of the slurry.

[0003] A scheme entitled “A Nickel Salt Slow Cooling Tank” (publication number CN208635396U, hereinafter referred to as Document 1) is disclosed, which cools the solution in the tank body through a built-in cooling device, wherein the cooling device includes a spiral coolant pipe ring, one end of the spiral coolant pipe ring is connected to the coolant inlet straight pipe, and the other end is connected to the coolant outlet straight pipe, the coolant inlet straight pipe is horizontally arranged, and the coolant outlet straight pipe is horizontally arranged.

[0004] The spiral coolant pipe ring in Document 1 is a whole, and there are the following problems when it is used: first, due to the scouring of materials, the spiral coolant pipe ring inside the slow cooling tank is often damaged and needs to be welded, but welding is difficult and requires high technical skills of the welder, and replacing it is a whole replacement, which takes a long time and has high maintenance costs; second, the flow path of the coolant is single, and the coolant flows from bottom to top. The same part of the coolant flows inside the slow cooling tank for a long time, affecting the cooling of the material at the top of the slow cooling tank, and the cooling effect is not good. Utility Model Content

[0005] The utility model aims to provide a cooling coil for a slow cooling tank, so as to improve the cooling effect on the material inside the slow cooling tank.

[0006] The utility model can be implemented through the following technical scheme: a slow cooling trough cooling coil, including an upper circle tube and a lower circle tube arranged in a horizontal plane, the upper and lower ends of the vertically arranged spiral tube are respectively connected to the upper circle tube and the lower circle tube via connecting flanges, and the spiral tubes are arranged at intervals within the circumferential range of the upper circle tube and the lower circle tube.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] The coolant flows along the lower circle tube, the spiral tube and the upper circle tube, taking away the heat of the material in the slow cooling trough to achieve cooling of the material; wherein an upper circle tube, a lower circle tube and a plurality of spiral tubes are provided, and both are connected by flanges, so that on the one hand, it is convenient to replace the upper circle tube, the lower circle tube and the spiral tube at the damaged position, and on the other hand, the coolant flows in a single spiral tube, and the length of its flow path is reduced, and the same part of the coolant will not flow in the slow cooling trough for a long time, thereby ensuring that the material at the top of the slow cooling trough can be cooled in time; at the same time, since the overall length of the cooling coil composed of the upper circle tube, the lower circle tube and the spiral tube is relatively long, the contact area between the cooling coil and the material in the slow cooling trough is increased, and then in the same time, the cooling coil used in the present application can take away more heat in the slow cooling trough, thereby improving the cooling efficiency.

[0013] See also Figure 1-4 As shown, a slow cooling tank cooling coil comprises an upper coil tube 10 and a lower coil tube 20 arranged with coil surfaces located in a horizontal plane, the upper and lower ends of a vertically arranged spiral tube 30 are respectively connected to the upper coil tube 10 and the lower coil tube 20 via connecting flanges, and the spiral tubes 30 are arranged at intervals within the circumferential range of the upper coil tube 10 and the lower coil tube 20; a water outlet pipe 40 is connected to the pipe wall of the upper coil tube 10, and a water inlet pipe 50 is connected to the pipe wall of the lower coil tube 20;

[0014] In the above scheme, the coolant flows in from the water inlet pipe 40 on the lower circle tube 20, then flows along the tube cavity of the lower circle tube 20, and enters the spiral tube 30 from the lower end of each spiral tube 30 respectively. The coolant entering the spiral tube 30 flows upward along the flow path of the spiral tube 30, and finally flows out from the upper end of the spiral tube 30, and enters the upper circle tube 10, and finally is discharged from the water outlet pipe 40 of the upper circle tube 10, completing the entire flow process in the slow cooling tank, thereby taking away the heat of the material (such as anode mud material) in the slow cooling tank, and realizing the cooling of the material; wherein the upper circle tube 10, the lower circle tube 20 and the plurality of spiral tubes 30 are arranged, and both are connected The flange connection facilitates the replacement of the upper circle tube 10, the lower circle tube 20 and the spiral tube 30 at the damaged position on the one hand, and on the other hand, the coolant flows in a single spiral tube 30, and the length of its flow path is reduced. The same part of the coolant will not flow in the slow cooling tank for a long time, thereby ensuring that the material at the top of the slow cooling tank can be cooled in time; at the same time, since the overall length of the cooling coil composed of the upper circle tube 10, the lower circle tube 20 and the spiral tube 30 is relatively long, the contact area between the cooling coil and the material in the slow cooling tank is increased, and then in the same time, the cooling coil used in the present application can take away more heat in the slow cooling tank, thereby improving the cooling efficiency.

[0015] In the above, the upper tube 10 is composed of two arc-shaped upper tube unit tubes 11, and the tube ends of the two upper tube unit tubes 11 are connected via the upper tube connecting flange 12. The lower tube 20 is composed of two arc-shaped lower tube unit tubes 21, and the two lower tube unit tubes 21 are connected at the tube ends via the lower tube connecting flange 22; by dividing the upper tube 10 into two upper tube unit tubes 11, when one of the upper tube unit tubes 11 on the upper tube 10 is damaged and needs to be replaced, only one of the upper tube unit tubes 11 needs to be replaced, thereby reducing the maintenance amount, and the two upper tube unit tubes 11 are connected by the upper tube connecting flange 12, which is convenient to replace; similarly, the same is true for the lower pipe 20. In this way, the molding cost and the amount of accessories of the upper tube 10 can be reduced while improving the molding quality of the upper tube 10.

[0016] The upper tube 10 and the lower tube 20 have the same shape and size, and the center of the upper tube 10 and the center of the lower tube 20 are on the same vertical line; on the one hand, the spiral tube 30 can be arranged between the upper tube 10 and the lower tube 20 at equal intervals, and on the other hand, it is convenient to replace the upper tube 10 and the lower tube 20. This solution is particularly suitable for cylindrical slow cooling tanks. The upper tube 10 and the lower tube 20 have the same shape and size, which can reduce the pre-stock of accessories.

[0017] Lower tube connecting pipes 23 are arranged at intervals within the circumferential range of the lower tube 20, and the lower tube connecting pipes 23 are connected to the spiral tube 30 via the lower tube connecting pipe flange 24; the coolant in the lower tube 20 flows through the lower tube connecting pipe 23 and the lower tube connecting pipe flange 24 in sequence, and then enters the spiral tube 30. Upper tube connecting pipes 13 are arranged at intervals within the circumferential range of the upper tube 10, and the upper tube connecting pipe 13 is connected to the spiral tube 30 via the upper tube connecting pipe flange 14; the coolant in the spiral tube 30 flows through the upper tube connecting pipe flange 14 and the upper tube connecting pipe 13 in sequence, and then enters the upper tube 10, and finally flows out from the water outlet pipe 40.
