DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] refer to Figure 1-2 As shown, the utility model provides a novel domestic sewage treatment device, comprising: a tank body 1 with a sewage pipe 3 at the bottom, a heater 2 is provided between the tank body 1 and the sewage pipe 3, a heating chamber 11 wrapped around the bottom of the tank body 1 is formed in the heater 2, a heating element for electric heating is provided in the heating chamber 11, and the heating element is used to form a high-temperature area between the tank body 1 and the sewage pipe 3.
[0024] Combination Figure 5 As shown, the tank body 1 includes a clean water tank, a membrane tank, a pretreatment tank A, a pretreatment tank B, a pretreatment tank C, a pretreatment tank D and a regulating tank.
[0025] As mentioned above, when using the tank body 1, sewage pipe 3 and heater 2 provided by the utility model, by arranging the heater 2 between the tank body 1 and the sewage pipe 3, the moisture accumulated in the tank body 1 is heated, and the moisture is prevented from freezing or the condensed ice is melted under low temperature conditions, so that the moisture accumulated in the tank body 1 can be smoothly discharged from the tank body 1, keeping the tank body 1 dry and clean, reducing the probability of corrosion of the tank body 1, and extending the service life of the tank body 1. In addition, the structure of the domestic sewage tank body 1 is simple and easy to implement.
[0026] Further, in order to prevent the sewage from sticking to the inner wall of the tank 1, refer to Figure 2 As shown, a hydrophobic coating 8 for repelling water is also sprayed on the inner wall of the tank body 1. The inner wall of the tank body 1 is covered with a hydrophobic coating 8. The hydrophobic coating 8 can be selected from various coatings that have the function of reducing the adhesion of the material surface, such as polysiloxane hydrophobic coatings, fluoroalkylsiloxane hydrophobic coatings, fluoropolymer hydrophobic coatings, etc. Due to the presence of the hydrophobic coating 8 on the inner wall of the tank body 1, the moisture in the compressed air in the tank body 1 will not adhere to the inner wall after condensing on the inner wall, but will flow downward along the inner wall of the tank body 1 and enter the heating area at the bottom of the tank body 1. By covering the inner wall of the tank body 1 with a hydrophobic coating 8, the adhesion of moisture to the inner wall of the tank body 1 can be greatly reduced, so that most of the moisture flows into the heating area, further reducing the moisture content in the tank body 1, and achieving better drying and cleaning effects.
[0027] In the present utility model, combined with Figure 2-4As shown, the heater 2 of this embodiment includes a detachable mounting base 4 and a cover plate 5, which are arranged in sequence from top to bottom. The mounting base 4 is fitted on the bottom of the tank body 1, and a heating chamber 11 is formed between the mounting base 4 and the cover plate 5. A sleeve 7 which is sleeved on the sewage pipe 3 is provided in the middle of the mounting base 4, and a through hole 9 which is sleeved on the sleeve 7 is opened in the middle of the cover plate 5.
[0028] As described above, when using the mounting base 4 and the cover plate 5 provided by the utility model, the mounting base 4 provides a mounting position for the heating element at the bottom of the tank body 1, and the sleeve 7 prevents the heating chamber 11 from directly contacting the sewage pipe 3, thereby preventing the sewage pipe 3 from being damaged by excessive temperature.
[0029] Further, in order to facilitate the maintenance of the heating element, refer to Figure 1-4 As shown, a plurality of threaded holes 10 extending into the mounting seat 4 are provided at the bottom of the cover plate 5 along the edge, and a fastening bolt 6 for connecting the cover plate 5 and the mounting seat 4 is provided in each threaded hole 10. A plurality of fastening bolts 6 can be installed between the mounting seat 4 and the cover plate 5 through the plurality of threaded holes 10. After the fastening bolts 6 are removed, the cover plate 5 can be separated from the mounting seat 4, thereby facilitating the inspection and repair of the heating element in the heating chamber 11.
[0030] In the present utility model, combined with Figure 2-3 As shown, the heating element of this embodiment includes a plurality of heating ring tubes 12 with successively decreasing diameters, and the plurality of heating ring tubes 12 are sequentially and equidistantly distributed outwardly from the sleeve 7 as the center on the mounting seat 4 .
[0031] As described above, when the heating loop tube 12 provided by the present invention is used, the temperature of each position at the bottom of the tank body 1 can be increased by using a plurality of heating loop tubes 12 .
[0032] Further, in order to increase the heating speed of the heating ring tube 12, refer to Figure 2-3 As shown, a heat conducting plate 14 for heat conduction is attached to one side of the mounting seat 4 close to the cover plate 5, and multiple mounting brackets 13 welded to the heat conducting plate 14 are provided on the multiple heating loops 12, and a heat insulating layer 15 for heat insulation is provided on one side of the cover plate 5 close to the mounting seat 4. The mounting bracket 13 facilitates the integration of the heating loop 12 on the heat conducting plate 14, and the heat conducting plate 14 facilitates the rapid transfer of heat heated by the heating loop 12 to the mounting seat 4, thereby facilitating the transfer of heat to the bottom of the tank body 1 through the mounting seat 4, and the heat insulating layer 15 prevents the heat from being released outward through the cover plate 5.
[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
