Description

Technical Field

[0001] The utility model relates to the technical field of lead ingot production equipment, in particular to an online spray device for preventing lead ingots from sticking. Background Art

[0002] Lead (Pb) is a high-density, low-melting-point, soft blue-gray metal. The density of lead is 11.34g / cm3, the melting point is 327℃, and the crystal structure of lead is a cubic lattice. It has low hardness, softness, and strong ductility. The characteristics of lead with high density, softness, and strong ductility determine that when the lead ingots are stacked, if the temperature is too high, the hardness of the lead ingots is insufficient, and the bottom lead ingots are prone to adhesion due to gravity. The adhesion of the lead ingots affects the next step of separation and processing, and increases the safety risk during the operation. The current solution to this problem is to fully cool the lead ingots and reduce the chance of adhesion by increasing the cooling water circulation volume, reducing the cooling water temperature, slowing down the speed of the ingot casting machine, and extending the cooling time.

[0003] This approach has the following disadvantages:

[0004] 1) Increased equipment investment. Increasing the cooling water circulation volume and lowering the cooling water temperature require a higher-power water pump, a cooling tower with greater cooling capacity, and more construction area, which requires a larger one-time investment. Later equipment operation also requires more water and electricity, and the production cost increases accordingly.

[0005] 2) Reduced production capacity. Slowing down the speed of the ingot casting machine and extending the cooling time will break the original balance between refining and ingot casting. Refining and ingot casting will cause a mismatch between the two times, which will eventually lead to a decrease in ingot casting capacity per unit time and an increase in cost.

[0006] 3) Energy waste. The lead ingots usually stick together only in the bottom three layers. The upper lead ingots are relatively less subject to gravity and generally do not stick together. However, the existing technology reduces the temperature of all lead ingots, resulting in a decrease in the cooling efficiency of the cooling water. Utility Model Content

DETAILED DESCRIPTION

[0030] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0031] like Figure 1 As shown, an online spray device for preventing lead ingots from sticking comprises a hanger 1, a first substrate 2 located below the hanger, a second substrate 3 located below the first substrate and an atomizing cooling mechanism. The hanger is provided with a lifting mechanism for driving the first substrate to move up and down along the hanger and a translation mechanism for driving the first substrate to move horizontally along the hanger. The hanger is provided with a movable plate 6, which is slidably connected to a guide rail 7 arranged along the length direction of the hanger. The lifting mechanism and the translation mechanism are both connected to the movable plate. The first substrate is provided with a rotating mechanism for driving the second substrate to rotate along it. The second substrate is provided with a lead ingot clamping mechanism. The atomizing cooling mechanism comprises an atomizing nozzle 4 and an atomizing water pipe 5. The atomizing nozzle is connected to the atomizing water pipe. The atomizing nozzle is located at the bottom of the second substrate. The atomizing water pipe is provided with an electromagnetic valve. The electromagnetic valve is connected to the control system of the lead ingot production line to automatically control the spraying time and spraying amount of cooling water. The atomizing cooling water of the utility model is transported by compressed air, which will not be described in detail here. The utility model discloses an online spray device for preventing lead ingots from sticking, which is installed at the discharge port of a lead ingot conveyor line. A lead ingot clamping mechanism is used to clamp the lead ingots on the production line, and the clamped lead ingots are transferred, stacked and piled by a lifting mechanism, a translation mechanism and a rotating mechanism respectively. During the clamping and transportation process, an atomizing nozzle sprays cooling water on the surface of the lead ingots to achieve direct and rapid cooling.

[0032] like Figure 1 and Figure 2 As shown, the lifting mechanism includes a lifting cylinder 8 and a guide column 9. The lifting cylinder is vertically installed on the movable plate, and its output shaft is connected to the first base plate. One end of the guide column is connected to the first base plate, and the other end passes through the movable plate and is slidably connected to the movable plate. The lifting cylinder controls the lifting of the first base plate, thereby driving the second base plate, the lead ingot clamping mechanism and the lead ingot to perform lifting movements, which is convenient for stacking the lead ingots.

[0033] Combination Figures 1 to 5 As shown, the translation mechanism includes a translation motor 10, a gear 11 and a rack 12. The translation motor is installed on the moving plate and connected to the gear. The gear is connected with the rack arranged along the length direction of the hanger. The translation motor drives the gear to rotate, and the gear is meshed with the rack, thereby driving the moving plate to slide horizontally along the guide rail, and finally driving the horizontal movement of the first substrate, the second substrate, and the lead ingot clamping mechanism. Figure 3As shown, the rotating mechanism includes a rotating cylinder 13, a rotating shaft 14 and a cam 15. One end of the rotating shaft is connected to the second substrate, and the other end is rotatably connected to the first substrate. The cam is connected to one side of the rotating shaft. The rotating cylinder is installed on the first substrate and hinged with the cam. The extension and retraction of the output shaft of the rotating cylinder drives the cam to swing, thereby driving the rotating shaft to rotate and adjusting the stacking direction of the lead ingots.

[0034] like Figure 1 and Figure 2 As shown, the lead ingot clamping mechanism includes two clamping components symmetrically arranged on both sides of the second substrate. The two clamping components can work synchronously to clamp the lead ingot. Each clamping component includes a clamping cylinder 16, a support arm 17, a rotating arm 18 and a clamping block 19. The clamping cylinder is fixedly installed on the second substrate, and its output shaft is hinged to one end of the rotating arm, and the other end of the rotating arm is connected to the clamping block. The middle part of the rotating arm is hinged to the support arm fixed on the second substrate. By lever rotation, when the output shafts of the two clamping cylinders are synchronously extended, the upper ends of the two rotating arms swing to the two sides of the second substrate respectively, and the two clamping blocks swing in opposite directions, that is, the distance between the two clamping blocks is reduced, and the lead ingot is clamped and fixed; conversely, when the output shafts of the two clamping cylinders are synchronously contracted, the distance between the two clamping blocks is increased, and the lead ingot can be loosened. The vertical cross-section of the clamping block is L-shaped, which can hold the end of the lead ingot to improve its stability. A lead ingot limiting block 20 is also provided at the bottom of the second substrate to quickly position the lead ingot. The lead ingot is clamped more firmly during transportation without slipping, which is safe and reliable.

[0035] The working principle of the utility model is as follows:

[0036] like Figure 1 As shown, the utility model is installed at the discharge port of the conveying device of the lead ingot production line, the lead ingot 22 is conveyed by the conveying device, a blocking device is added at the discharge port, the utility model is moved to the top of the discharge port of the conveying device, the lifting cylinder 8 drives the first substrate 2, the second substrate 3 and the lead ingot clamping mechanism to descend, when the lead ingot limit block 20 conflicts with the upper surface of the lead ingot, the two clamping cylinders 16 work, drive the two clamping blocks 19 to move to clamp the lead ingot 22, the production line control system starts the solenoid valve 21, the atomizing nozzle 4 sprays cooling water to the surface of the lead ingot 22 for rapid cooling, the lifting cylinder 8 and the translation motor 10 work, the clamped lead ingot 22 is hoisted and transported to the specified position, and then the lead ingot 22 is stacked and placed, and the two clamping blocks 19 are released; then a new round of lead ingot 22 clamping, transportation and stacking process is started.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
