[0004] Although the explosion-proof electric heater with a protective function can filter the incoming liquid to prevent impurities from entering the heating chamber through the provided filter tube, filter screen and connecting flange, the filter screen of the explosion-proof electric heater with a protective function is blocked by impurities in the liquid, which reduces the rate at which the liquid enters the heating chamber. The filter screen needs to be cleaned regularly, which is more troublesome to use.

[0005] Therefore, we proposed a thermal insulation and energy-saving explosion-proof electric heater. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a thermal insulation, energy-saving explosion-proof electric heater, which solves the problem that the filter of the existing device is clogged by impurities in the liquid, which reduces the rate at which the liquid enters the heating chamber and requires regular cleaning of the filter, making it more troublesome to use.

[0010] Preferably, the brush is in contact with the surface of the protective tube and is opposite to the position of the filter hole. When the liquid is discharged into the heating chamber through the liquid inlet pipe, the liquid will impact the blades, which will then drive the ring to rotate. When the ring rotates, it can drive the connecting plate and the brush to rotate around the outside of the protective tube, and then the impurities attached to the protective tube are cleaned off by the brush, which helps to avoid the filter hole being blocked by impurities.

[0011] Preferably, a sewage pipe connected to the heating chamber is fixedly installed in the middle of the bottom side of the explosion-proof heat-insulating shell, wherein impurities inside the heating chamber can be discharged through the sewage pipe.

[0014] The utility model provides a heat-insulating, energy-saving explosion-proof electric heater. It has the following beneficial effects:

[0015] The heat-insulating and energy-saving explosion-proof electric heater transports external liquid to the interior of the heating chamber through the liquid inlet pipe. The liquid passes through the liquid inlet pipe and impacts on the blades, and then drives the sleeve ring and the connecting plate to rotate along the outer surface of the protective tube. The liquid passes through the filter hole and enters the interior of the protective tube. Impurities in the liquid are filtered by the filter hole, which can prevent the impurities from contacting the heating tube and preventing the impurities from adhering to the heating tube, thereby reducing the heating efficiency of the heating tube, which is beneficial to saving electric energy and avoiding the situation that the liquid directly impacts the heating tube and causes damage to the heating tube, which is beneficial to protecting the heating tube. When the connecting plate rotates, it can drive the brush to brush the outer surface of the protective tube, and then clean up the impurities attached to the protective tube. The electromagnetic valve on the drain pipe can be opened to discharge the impurities in the heating chamber, thereby preventing the impurities from clogging the filter hole. The cleaning process of the protective tube does not require additional electric energy, and the cleaning process is energy-saving and environmentally friendly. It is simple and convenient to use, and solves the problem that after the filter net of the existing device is clogged by impurities in the liquid, the rate at which the liquid enters the interior of the heating chamber is reduced, and the filter net needs to be cleaned regularly, which is troublesome to use.
