TECHNICAL FIELD

[0001] The utility model belongs to the smelting field, concretely relates to a kind of anode plate cooling tank. BACKGROUND

[0002] The process of copper concentrate fire smelting production anode copper is generally first to make copper sulfide concentrate through sulfur smelting to obtain copper matte, then send copper matte into blowing furnace and blow to become crude copper, and after the desulfurization and deoxidation of crude copper in anode furnace, the purity of anode copper is 99.5%.

[0003] The anode refining process of copper smelting is to obtain copper water with the purity of 99.5% and the temperature of 1150-1200℃ from anode furnace, and the high-temperature copper water is cast into anode plate by disc casting machine, and the temperature of anode plate is generally several hundred degrees Celsius when it is extracted by extraction machine, so it needs to be immersed in water tank for further cooling, and the cooling water of water tank adopts the circulation mode of bottom water inlet and upper overflow, and this cooling water circulation mode has many defects: the water level of water tank is slow to adjust, it is easy to boil due to high water temperature, which leads to splashing and hurting people everywhere, the scene has a lot of water vapor, the environment has poor visibility, it is easy to cause safety accidents and white pollution, and the cooling effect is poor. SUMMARY

[0009] The technical scheme of the utility model will be described further in connection with the drawings.

[0010] An anode plate cooling tank, comprising a cooling tank 10, a spraying device 20 is arranged on the groove edge of the cooling tank 10, the nozzle 21 of the spraying device 20 points to the opposite side groove wall and the water outlet falls into the groove of the cooling tank 10, and the water outlet pipe 11 of the cooling tank 10 is connected to the water inlet 22 of the spraying device 20 through a circulating pump 30. Figure 1 As shown in the figure, the spraying device 20 is arranged on the two side groove edges of the cooling tank 10, which greatly improves the stability of the cooling tank, and in the conventional case, the conveying device needs to be arranged in the cooling tank 10 to move the anode plate A to be cooled from the leading end to the other end, and the corresponding conveying equipment and the moving process of the anode plate will cause certain damage to the cooling tank, the arrangement of the spraying device 20 greatly improves the stability of the cooling tank and saves the maintenance and repair time of the cooling tank 10.

[0011] Specifically, as shown in the figure, Figures 1-3 The cooling tank 10 is a rectangular straight tank. When the anode plate A to be cooled enters the cooling tank, it enters from above one short side of the cooling tank 10, which can be called the leading end of the anode plate A to be cooled. At this time, the anode plate A to be cooled is in an inclined state (as shown in the figure), Figure 2 、 3 The water sprayed from the spraying device 20 is directly sprayed on the anode plate A to be cooled to preliminarily cool it, which can avoid the deformation of the anode plate caused by the sudden temperature drop when the anode plate A to be cooled directly enters the cooling tank 10, and the pollution of the environment by a large amount of water vapor. Secondly, the cooling effect of the anode plate A to be cooled is better in a limited cooling time. Thirdly, the temperature of the anode plate A to be cooled is as high as several hundred degrees Celsius, even after preliminary cooling by spraying water, the temperature is still very high. When it enters the cooling water in the cooling tank 10, it can still make the cooling water boil. The newly added spraying device can also "suppress" the boiling cooling water, so that the high-temperature cooling water is appropriately cooled, so as not to roll, splash and smoke, which greatly improves the working environment of the anode plate cooling link.

[0012] The two opposite side groove edges of the cooling tank 10 near the groove end of the anode plate A to be cooled are provided with spraying devices 20, and the two branch pipes of the water outlet pipe of the circulating pump 30 are respectively connected to the water inlets 22 of the two spraying devices 20. Compared with the traditional cooling tank 10, the water level of the circulating cooling water is easier to control, and the spraying mode is also more conducive to the cooling of the circulating water, which further improves the cooling effect of the anode plate A to be cooled.

[0013] The spraying directions of the nozzles 21 of the spraying device 20 include horizontal directions pointing towards the opposite side wall of the tank, as well as upward and / or downward directions. Multiple spraying directions can increase the contact opportunity between the sprayed water and the anode plate A to be cooled, thereby improving the cooling effect. Since the anode plate A to be cooled only needs spraying for cooling at the inlet end of the cooling tank 10, theoretically, it is sufficient to install the spraying device 20 only at the corresponding location. Alternatively, to enhance the stability of the cooling tank 10, the spraying device 20 can extend to the entire edge of the tank on its side, requiring only nozzles 21 at the corresponding location. However, as a preferred solution, such as... Figure 1 As shown, nozzles are installed on the entire spray device 20. This is beneficial for cooling the circulating cooling water. Furthermore, since the cooling water temperature in the cooling tank 10 is high, more steam evaporates. Increasing the spray area of ​​the spray water helps to suppress the steam and reduce steam contamination. Of course, in actual operation, the size of the nozzles 21 can be flexibly set, or the spray intensity can be adjusted as needed. For example, the spray volume of the nozzles 21 near the inlet end of the anode plate A to be cooled can be increased to accelerate the cooling effect of the anode plate A and suppress the boiling cooling water in the cooling tank 10. The spray volume of the nozzles 21 at other locations can be appropriately reduced, only serving to absorb or suppress the steam.

[0014] The spraying device 20 is a steel pipe arranged along the length of the cooling tank 10, and the spray holes opened on the steel pipe constitute nozzles 21.

[0015] In the specific design, while adding a reinforcing device with angle steel on the upper part of the cooling tank 10, steel pipes and angle steel are welded together on the left and right sides of the cooling tank 10. φ8mm*20 holes (i.e., nozzles 21) are drilled 5cm apart on the angle steel. A DN32 shut-off valve is installed in front of the steel pipe for cooling water. The reinforcing angle steel on the tank serves as the cooling water pipe, and the DN32 shut-off valve serves as the regulating device for controlling the water volume and temperature. When the anode plate A to be cooled moves into the spray area of ​​the spray device 20 above the cooling tank 10, the cooling water on the angle steel cools the anode plate through the holes, and the surface is sprayed with water to enhance the cooling effect. The water level in the tank can be adjusted quickly, solving problems such as excessively high temperature of the circulating cooling water in the tank and insufficient cooling time for the anode plate. This improves the on-site environment, enhances the quality of the anode plate, and eliminates safety hazards.
