Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy wheel hubs, in particular to an aluminum alloy wheel hub wet repair system. Background Art

[0002] The wheels after casting and machining are polished and then put on the painting line. After the pre-treatment process and the three-spray and three-bake painting process (three sprays: foundation spray room, liquid spray room, powder spray room; three bakes: foundation baking oven, liquid baking oven, powder baking oven), a uniform coating is formed on the surface of the aluminum alloy wheel hub, which improves the aesthetics of the wheel hub and enhances its corrosion resistance and impact resistance to meet the needs of different customers.

[0003] In the prior art, conventional repair systems consist of two main components: 1. A fresh air exchange system consisting of an intake fan, an exhaust fan, and connected air ducts in the repair area; and 2. A paint mist filtering device consisting of a fixed size and number of plastic palm filters. Conventional repair systems, under the action of the air flow of the fresh air exchange system, complete their operation by filtering the paint mist that is ejected into the air by a high-pressure spray gun during the repair operation but does not cover the surface of the aluminum alloy wheel hub through a paint mist filtering device equipped with a plastic palm filter. However, when the aluminum alloy wheel hub is being repaired by spraying paint, a large amount of paint mist that is ejected into the air by the high-pressure spray gun but does not cover the surface of the aluminum alloy wheel hub is completely filtered by the plastic palm filter. A large amount of paint mist will quickly accumulate on the surface of the plastic palm filter in a short period of time, resulting in a high replacement frequency, increased consumption of the plastic palm filter, and high enterprise costs. Therefore, a new wet repair system for aluminum alloy wheels is needed. Utility Model Content

[0008] Preferably, a plurality of overflow grooves are equidistantly provided on the front surface of the baffle near the bottom. The baffle is located above the water reservoir, so that when the water inside the baffle is full, the overflowing water will flow evenly downward along the plurality of overflow grooves, forming a more uniform water curtain.

[0009] Preferably, the outer surface of the fixed frame is fixedly connected to the inner surface of the processing workshop near the top, and the front surface of the fixed frame is fitted with the rear surface of the baffle, so that when the fixed frame is fixed inside the processing workshop, it fits with the surface of the baffle to prevent part of the gas from bypassing the filter and affecting the filtering effect.

[0025] like Figure 2 As shown, a water reservoir 10 is provided at the inner bottom of the processing workshop 1, and the pump body 804 is located at the inner bottom of the water reservoir 10, so as to facilitate the collection and recovery of the flowing water curtain. When the pump body 804 is working, the water in the water reservoir 10 is extracted to facilitate the recycling of the water.

[0026] like Figure 4 As shown, the front surface of the diverter block 802 is fixedly connected to the rear surface of the baffle 801, and the outer surfaces of the multiple branch pipes 806 are movable through the outer surface of the baffle 801. The water in the diverter block 802 can be evenly and quickly injected into the interior of the baffle 801 under the action of the multiple branch pipes 806, so that the water can flow out evenly from the multiple drip holes 805.

[0027] like Figure 2-4 As shown, a plurality of overflow grooves 807 are equidistantly provided on the front surface of the baffle 801 near the bottom. The baffle 801 is located above the water reservoir 10, so that when the water inside the baffle 801 is full, the overflowing water will flow evenly downward along the plurality of overflow grooves 807, forming a more uniform water curtain.

[0028] like Figure 2 As shown, the outer surface of the fixed frame 901 is fixedly connected to the inner surface of the processing workshop 1 near the top, and the front surface of the fixed frame 901 is in contact with the rear surface of the baffle 801, so that when the fixed frame 901 is fixed inside the processing workshop 1, it is in contact with the surface of the baffle 801 to prevent some gas from bypassing the filter 902 and affecting the filtering effect.

[0031] The method of use and working principle of this device: When in use, when personnel are performing paint repair work on aluminum alloy wheels in the processing workshop 1, the intake fan 6 and the exhaust fan 7 are started synchronously, so that when they are working, the outside air enters the processing workshop 1 through the first pipe body 4 and the first cover body 2, and the replaced gas in the processing workshop 1 bypasses from the bottom of the baffle 801, passes through the fixed frame 901 from bottom to top, and enters the second cover body 3, and is transported out through the second pipe body 5 to form a fresh air exchange system. During the flow of air, the pump body 804 in the water reservoir 10 is started, and the pump body 804 will The treated water in the water reservoir 10 is sucked and transported to the diversion block 802 through the delivery pipe 803, and flows out evenly from multiple branch pipes 806, so that it is quickly injected into the interior of the baffle 801. The internal water flow of the baffle 801 flows out evenly from multiple drip holes 805 to form a first water curtain. When the water overflowing from the baffle 801 flows downward along multiple overflow grooves 807, it will form a uniform second water curtain. The water of the two water curtains flows into the water reservoir 10. The water reservoir 10 is equipped with a paint residue water treatment device.

A small amount of paint mist will rise with the water vapor after passing through the gaps in the water curtain with the air flow. Under the action of the water barrier 903 and the through groove 904, most of the water molecules in the rising air flow condense into water when they come into contact with the surface of the water barrier 903, removing Most of the moisture in the rising gas and the residual paint mist in the rising gas will be intercepted and filtered by the stainless steel filter 902. The filtered air is discharged through the second tube 5 connected to the exhaust fan 7 under the power of the exhaust fan. During the aluminum alloy wheel hub repair process, most of the paint mist will be carried away by the continuous water curtain flow, and the residual paint mist will be filtered by the stainless steel filter 902, thereby reducing the filtering burden of the filter 902, reducing its replacement frequency, reducing the consumption of the filter 902, and improving the use effect of the aluminum alloy wheel hub wet repair system.
