Pretreatment washing device for coating of aluminum alloy automobile hub

Abstract

The invention discloses a pretreatment washing device for coating of an aluminum alloy automobile hub. The pretreatment washing device for coating of the aluminum alloy automobile hub comprises a cleaning operation box and is characterized by further comprising a water supplementing pipe, a water supplementing valve, a water tank, a water recycling pipe, a water pump water inlet pipe, a water pump, a check valve, a cleaning operation box water inlet pipe, a hot water tower, a hot water pipe, a heat exchanger, an air compressor cooling liquid inlet pipe, an air compressor chamber, an air compressor cooling liquid outlet pipe, a heat exchange pipe group, a water pump water outlet pipe and a plurality of air compressors. The heat exchange pipe group comprises an S-shaped heat exchange water pipe and an S-shaped heat exchange cooling liquid pipe. The heat exchange pipe group is installed in the heat exchanger. The air compressor is installed in the sealed air compressor chamber. A liquid outlet of each air compressor is connected with the left end of the S-shaped heat exchange cooling liquid pipe in the heat exchanger through the air compressor cooling liquid outlet pipe. The pretreatment washing device for coating of the aluminum alloy automobile hub is novel in structure, high in heat energy utilization rate, low in cost, environmentally friendly, safe and reliable in operation.

Description

technical field [0001] The invention relates to automobile processing equipment, in particular to a pre-painting cleaning device for aluminum alloy automobile wheel hubs. Background technique [0002] Before painting, the automobile wheel hub needs to be cleaned to remove dirt. When cleaning, there are technological requirements for the water temperature, and the cleaning water needs to be heated. After the water temperature meets the technological requirements, the cleaning work can be carried out. The existing heating water There are usually two methods, one is to use gas to heat water, and the other is to use electric water to heat water. Both of the above two methods consume a lot of energy and use costs. Will pollute the environment. Contents of the invention [0003] The object of the present invention is to provide a pre-painting and cleaning device for aluminum alloy automobile wheels with novel structure, high heat energy utilization rate, low cost, environmental...
