[0029] The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0030] As Figures 1 to 7 shown, in one embodiment, a kind of anti-bleeding polyurea coating preparation device for seawater desalination project, including mixing bucket, mixing bucket includes mixing cavity 1 and heat preservation chamber 2, heat preservation chamber 2 is fixedly covered in the outside of mixing cavity 1, heat preservation chamber 2 includes heat preservation cavity 201, pumping cavity 202, reflux cavity 203 and plug interface 204, water pump 3 is provided in pumping cavity 202, the water suction end of water pump 3 is communicated with plug interface 204, the water outlet end of water pump 3 is communicated with heat preservation cavity 201, plug interface 204 is communicated with reflux cavity 203 by first communication port 4, heat preservation cavity 201 is communicated with reflux cavity 203 by second communication port 5, water inlet 6 is set in the top of heat preservation chamber 2;

[0031] The bottom end of heat preservation chamber 2 is threadedly sleeved with heating chamber 21, the top of heating chamber 21 is communicated with plug 7, plug 7 is inserted in plug interface 204, third port 8 is formed in the side of the end of plug 7, reflux pipe 9 is communicated with the other side of the end of plug 7, the bottom end of reflux pipe 9 extends to the inside bottom end of heating chamber 21, the top end of reflux pipe 9 is communicated with second communication port 5, heating wire 10 is provided in heating chamber 21.

[0032] The surface of the plug-in head 7 is sleeved with a sealing ring 11, which is in contact with the bottom surface of the heat preservation chamber 2 and the top surface of the heating chamber 21 respectively.

[0033] It should be understood that, in the process of screwing the heat preservation chamber 2 and the heating chamber 21, the plug-in head 7 will be gradually inserted into the plug-in interface 204 until the sealing ring 11 is in close contact with the bottom surface of the heat preservation chamber 2 and the top surface of the heating chamber 21 respectively, realizing the butt joint communication and ensuring the sealing performance;

[0034] When the butt joint of the plug-in head 7 and the plug-in interface 204 is completed, the top end of the return pipe 9 is in butt joint communication with the second communication port 5, water is injected into the heat preservation chamber 2 through the water injection port 6, and the water will enter the heating chamber 21 through the second communication port 5 and the return pipe 9 until the water depth reaches a position close to the water injection port 6, and the water injection is stopped. At this time, the heating wire 10 is electrified, and the water pump 3 will suck the water in the heating chamber 21 into the water pump 3 through the third communication port 8 and the plug-in interface 204, and then discharge the sucked heated water to the heat preservation cavity 201.

[0040] It should be understood that by separating the heat preservation cavity 201 into the first cavity 20101 and the second cavity 20102, the water can be shunted, so that the problem that the temperature of water at a higher position in the heat preservation cavity 201 cannot be guaranteed after the heated water enters the heat preservation cavity 201 from the inner bottom end of the heat preservation cavity 201 and backflows into the backflow cavity 203, so that the water heated and pumped into the first cavity 20101 needs to flow upward to the height of the shunt hole 18 before being shunted into the second cavity 20102, which is conducive to reducing the temperature difference of water at different depths in the heat preservation cavity 201.
