Embodiment Construction

[0015] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0016] see figure 1 and figure 2 As shown, in this embodiment, a heated integrated urea tube includes a nylon tube body 1 for transporting urea, the end of the nylon tube body 1 is provided with a quick-plug joint 2, and the nylon tube body 1 The outer jacket is provided with a corrugated tube 3, and the connection between the quick-plug connector 2 and the nylon tube body 1 is provided with an overflow stopper 4, and the nylon tube body 1 is wound with a helical tube body heating wire 5. The pipe body heating wire 5 is covered with a Teflon high temperature resistant layer, and the quick-plug connector 2 is evenly wound with a spiral joint heating wire 6, and the joint heating wire 6 is covered with a high temperature resistant tape for fixing. Finally, it is packaged with plastic to form an int...

Abstract

The invention discloses a heating type integrated urea pipe which comprises a urea pipe body. A quick insertion connector is arranged at the end of the urea pipe body, a spiral pipe body heating wire is wound around the urea pipe body, and a spiral connector heating wire is evenly wound around the quick insertion connector. According to the heating type integrated urea pipe, integrated type pipe heating is adopted, the heating speed is high, the performance is stable, and the heating type integrated urea pipe is safer than a traditional PTC heating belt. In addition, heating is more even, the unfreezing efficiency is greatly improved, the heating type integrated urea pipe can start unfreezing within 5 minutes and achieve complete unfreezing within 10 minutes, and the heating and unfreezing time is greatly shortened. The resistance value of the heating wire is fixed, the overall pipe heating power is stable and unchanged, the highest heating temperature is controlled to range from 70 DEG C to 80 DEG C, urea is prevented from going bad due to high temperature, and unnecessary losses are reduced.

Description

technical field [0001] The invention belongs to the diesel engine tail gas treatment technology, and in particular relates to a heated integrated urea pipe for transmitting urea solution in an SCR system. Background technique [0002] The urea pipe is the pipeline used to transport urea in the SCR system. In winter, urea will solidify at low temperature, causing the urea to not be sprayed out, and the SCR system to stop working. Therefore, in order to ensure the normal use of the vehicle, there is a heating urea tube on the market that can melt the solidified urea into liquid. This urea tube The principle of heating is to bind a PTC heating belt in parallel outside the urea tube. Although this kind of urea tube can melt urea, this heating method is not safe, and the joint part cannot be completely thawed; and the heating speed is slow, generally it takes 30 minutes to melt urea, and the energy consumption is high. Contents of the invention [0003] The purpose of the pre...
