Description

Technical Field

[0001] The utility model relates to the technical field of aluminum foil rolling mill equipment, in particular to a temperature-controllable splash-proof plate. Background Art

[0002] During the aluminum foil rolling process, the working rolls rotate at high speed, and rolling oil will be thrown out between the working rolls and the support rolls, resulting in rolling oil appearing on the surface of the aluminum foil. In order to prevent the rolling oil from falling onto the surface of the aluminum foil and affecting the product quality, a splash guard is usually installed at the outlet of the rolling mill to receive the rolling oil and divert it to both sides. At the same time, a surface purge device is installed on the splash guard to purge the oil droplets on the surface of the aluminum foil.

[0003] The existing splash guard can already well receive the splashed rolling oil, and the upper surface purge device can also effectively purge the oil droplets on the surface of the aluminum foil. When the rolling mill is working, a large amount of oil smoke will be formed at its outlet, some of which will be sucked away by the fan in the rolling mill, but some of the oil smoke will not be sucked away by the fan. When the ambient temperature is low, the temperature of the splash guard body will also be low. At this time, the oil smoke will condense into oil droplets on the splash guard, and then drip onto the surface of the aluminum foil to form oil spots. The upper surface purge device is installed at the bottom of the splash guard and consists of a row of nozzles. When the ambient temperature is low, the surface temperature of the purge nozzle is low, and the oil smoke will also form oil droplets on the surface of the nozzle, which will be blown to the surface of the aluminum foil with compressed air, affecting the product quality of the aluminum foil. Summary of the invention

[0004] In order to solve the problem that when the ambient temperature is low, part of the oil smoke that is not blown away by the fan will condense into oil droplets on the splash plate due to the low temperature of the splash plate, and then drip onto the surface of the aluminum foil to form oil spots, and the surface temperature of the purging nozzle is low, the oil smoke will also form oil droplets on the nozzle surface, and as the compressed air is purged to the surface of the aluminum foil, affecting the quality of the aluminum foil product, the utility model proposes a temperature-controllable splash plate, which heats the high-pressure air sprayed into the air storage box by a heater. At this time, the high-temperature high-pressure air will transfer temperature in the air storage box, thereby ensuring the temperature stability of the splash plate body and the nozzle, and avoiding the oil smoke condensing into oil droplets on the splash plate and the nozzle and flowing onto the aluminum foil to affect the product quality of the aluminum foil when the temperature of the splash plate and the nozzle is low.

[0008] Furthermore, a stop valve is provided on the main pipe, and a pressure regulating valve and a pressure gauge are also provided on each branch pipe. The pressure regulating valve is located between the heater and the main pipe, and the pressure gauge is located between the heater and the first air inlet pipe.

[0009] Furthermore, the lower side of the second splash plate is provided with a plurality of through slots connected to the air outlet, the through slots are arranged obliquely, and the nozzle is located in the through slots.

[0010] Furthermore, two baffles arranged opposite to each other are fixed on the upper side of the first splash plate to guide the rolling oil to the second splash plate, and then divert the rolling oil to both sides of the aluminum foil to prevent the oil droplets from contacting the aluminum foil.

[0011] Furthermore, a guide plate is fixed to the end of the second splash plate away from the first splash plate, and the cross section of the guide plate is a "U" shape with one long side and one short side. The oil smoke brought by the aluminum foil will directly hit the guide plate and then be diverted to both sides of the aluminum foil by the guide plate.

Figure 1 As shown, two oppositely disposed baffles 13 are fixed on the upper side of the first splash plate 1 .

[0025] In this embodiment, the air intake and outlet in the air storage box 3 are realized as follows: specifically, a plurality of air outlets are provided at the lower end of the air storage box 3 inside the second splash plate 2, each of the air outlets is installed with a nozzle 4, and a plurality of first air intake pipes 5 are connected to the upper side of the air storage box 3, and the air intake pipeline includes a main pipe and a plurality of branch pipes, one end of the main pipe is connected to the compressed air station 6, one end of the plurality of branch pipes is connected to the main pipe, and the other end is connected to the first air intake pipe 5, and each of the branch pipes is provided with a heater 7.

[0027] In this embodiment, a plurality of through slots 12 connected to the gas outlet are provided on the lower side of the second splash plate 2. The through slots 12 are arranged obliquely, and the nozzles 4 are located in the through slots 12. Figure 3 and Figure 5As shown, the inclined through slot 12 can converge the high-pressure air blown out by the nozzle 4, thereby improving the blowing effect on the surface of the aluminum foil.
