Fig. 1-2 show a preferred embodiment of the utility model, a waste heat utilization type oven structure for a profile electrophoresis line, comprising a preheating duct 1, a U-shaped burner 2. The opening 21 of the U-shaped combustion furnace 2 is engaged with the outlet of the preheating duct 1, and the first side wall 11 of the preheating duct 1 is connected with the side wall of the U-shaped combustion furnace 2, and the second side wall 12 of the preheating duct 1 is located between the opposite side walls of the U-shaped combustion furnace 2, so that the opening 21 of the U-shaped combustion furnace 2 is divided into a preheating wind branch port 211 and an overflow hot wind branch port 212. The preheating pipeline 1 is connected with a first exhaust fan 41 at a position far away from the U-shaped combustion furnace 2, and the first exhaust fan 41 is used for sucking hot gas in the U-shaped combustion furnace 2 into the preheating pipeline 1 and discharging the hot gas to the external environment.

During operation, the chain 7 hangs the work piece and passes through in this waste heat utilization formula oven structure that is used for section bar electrophoresis line, through preheating the preliminary heating of pipeline 1 to and after the high temperature stoving of U type burning furnace 2, alright thoroughly dry the work piece, then send out along overflow hot-blast branch mouth 212, pack after the work piece cools off or carry out the powder spraying technology as required can.

Obviously, by adding the preheating pipeline 1 on the basis of the U-shaped combustion furnace 2 and sucking the hot air in the U-shaped combustion furnace 2 into the preheating pipeline 1 by using the first exhaust fan 41 in parallel, more hot air flows to the preheating air branch port 211 instead of the overflow hot air branch port 212, the utilization of the waste heat and the preheating of workpieces are realized, the energy consumption is saved, and the phenomenon of workshop temperature rise caused by the escape of the hot air of the U-shaped combustion furnace 2 to a workshop is avoided. In addition, the negative pressure effect is generated based on the first exhaust fan 41, so that hot air is more difficult to escape along the overflow hot air branch port 212, thereby further reducing the temperature rise phenomenon of a workshop and further saving energy consumption. Moreover, the preheating pipeline 1 has a certain length, so that enough time can be reserved for the early preheating of the workpiece, and the working mechanism of continuous slow conveying of the chain 7 is matched more. In particular, the opening 21 based on the U-shaped burner 2 is engaged with the outlet of the preheating duct 1 and the hot air must pass through the opening 21 in order to overflow to the plant; the part of the opening 21 is the preheating wind branch opening 211, so that part of hot wind flows to the preheating wind branch opening 211, namely the escape amount of the hot wind is reduced; when the surplus hot air is ready to escape to the workshop through the overflow hot air branch port 212, the escape amount of the hot air is further reduced based on the negative pressure of the first exhaust fan 41, thereby further improving the utilization of the surplus hot air.

Referring to fig. 2, it is preferable that a section of the U-shaped furnace 2 near the preheating duct 1 (i.e., the entire section or a certain section) has an inclined structure, and its height gradually increases in a direction away from the preheating duct 1. In this way, the gas with higher temperature is always positioned at the top of the U-shaped combustion furnace 2 based on the rising characteristic of the gas with higher temperature, so that the workpiece is baked by the gas with high temperature, and the gas with lower temperature is sucked by the first exhaust fan 41 to the preheating pipeline 1 to preheat the workpiece, thereby saving more energy. And, at this time, the heat in the U-shaped combustion furnace 2 is more difficult to escape to the workshop along the overflow hot air branch port 212, so that the energy consumption is further saved.

Droplets attached to the surface of the workpiece based on the electrophoresis reaction may contain electrophoresis liquid, and the droplets are directly discharged into the external environment to cause great pollution. Therefore, it is preferable that the water spray tower 51, the UV photolysis purifier 52, and the activated carbon adsorption tower 53 are connected to the air outlet of the first exhaust fan 41 in this order.

In operation, under the coordination of the actual output power of first suction fan 41 and third suction fan 43, the negative pressure of first suction fan 41 is greater, thereby making the air flow more prone to first suction fan 41.

The workpiece is subjected to standing for a period of time through the standing chamber 6 and then enters the preheating passage, so that the energy consumption can be further reduced. Wherein, the standing chamber 6 is in sealing connection with the pipeline of the previous working procedure of the electrophoresis line.

In order to ensure that the preheating passage is in a negative pressure state with respect to the U-shaped combustion furnace 2, it is preferable that the first suction fans 41 are provided in plurality, the plurality of first suction fans 41 are arranged in parallel, and the outlets of the plurality of first suction fans 41 converge with each other.
