DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0025] Referring to the drawings Figures 1-7 A sewage treatment tank, comprising a tank body 1, the top of the tank body 1 is provided with a water inlet interface 2, the water inlet interface 2 is provided with a thread inside, so as to facilitate the butt joint of the pipeline, the bottom is provided with a water outlet 3, so as to facilitate the discharge of filtered water, the tank body 1 is provided with a filtering mechanism at the bottom of the water inlet interface 2, the sewage enters the tank body 1 through the water inlet interface 2, is filtered through the filtering mechanism and then is discharged through the water outlet 3.

[0026] The filtering mechanism comprises a filtering frame 41 arranged at the bottom of the water inlet interface 2, a plurality of filtering holes 42 arranged uniformly are formed in the bottom of the filtering frame 41, for filtering impurities in the sewage, the filtering frame 41 is provided with a floating plate 43, the floating plate 43 is in the form of a frame and can slide up and down along the inner wall of the filtering frame 41, the density of the floating plate 43 is less than that of water, so that the floating plate 43 can float up and down with the change of water level.

[0027] A pair of vertical plates 44 is symmetrically arranged at the bottom of the floating plate 43, a pair of vertical grooves 45 is formed in the bottom of the filtering frame 41 for the pair of vertical plates 44 to penetrate, the vertical plates 44 penetrate out of the vertical grooves 45 and are connected with a supporting plate 46, a plurality of through grooves are formed in the bottom of the supporting plate 46, so as to reduce the overall weight of the supporting plate 46.

[0028] A plurality of cleaning columns 47 arranged uniformly is arranged at the top of the supporting plate 46 corresponding to the filtering holes 42, the cleaning columns 47 can be inserted into the filtering holes 42 upwards to clean the impurities blocked in the filtering holes 42.

[0029] The cleaning column 47 comprises a tapered column at the top and a cylindrical column at the bottom, the diameter of the cylindrical column is smaller than that of the tapered column, the diameter of the tapered column is larger at the bottom and smaller at the top, the diameter of the bottom of the tapered column is smaller than the diameter of the inside of the filtering hole 42, so as to ensure that the cleaning column 47 can be smoothly inserted into the filtering hole 42, when the tapered column at the top of the cleaning column 47 is inserted into the filtering hole 42, the filtering hole 42 will not be completely blocked, so as to facilitate the filtering hole 42 to continue filtering the sewage.

[0030] The top of the tank 1 is equipped with a knob 5, and the bottom of the knob 5 is equipped with a rotating column 6 that is inserted into the tank 1. The bottom of the rotating column 6 is equipped with a connecting plate 7. The outer wall of the connecting plate 7 is equipped with a support frame 8 for supporting the filter mechanism. The filter mechanism is arranged circumferentially inside the tank 1 and is placed in the support frame 8. The top of the filter frame 41 is equipped with an outer edge on all four sides, so that when the filter frame 41 is placed in the support frame 8, the outer edge rests on the support frame 8, so as to facilitate the installation and disassembly of the filter mechanism and the support frame 8 and facilitate subsequent cleaning work.

[0031] The top of the tank 1 has an opening, and a lid 9 is provided on the opening. The size of the opening is larger than the size of the filter frame 41. The lid 9 has a handle on the top. The opening of the tank 1 can be opened by lifting the lid 9 with the handle, making it easy to take out the filter mechanism for cleaning.

[0032] Working principle: Wastewater enters tank 1 through inlet 2 and then enters filter frame 41 for filtration. When the filter hole 42 at the bottom of filter frame 41 is blocked, float plate 43 floats upward as the water level in filter frame 41 rises, and drives vertical plate 44 and support plate 46 to move upward. At this time, cleaning column 47 is inserted into filter hole 42 to clean the impurities blocked in filter hole 42. After cleaning, the water level in filter frame 41 will drop, and float plate 43 will move downward. Cleaning column 47 will withdraw from filter hole 42 to ensure that filter hole 42 is unobstructed.

[0033] After prolonged use, turn knob 5 to change the position of the circumferentially set filter mechanism, and then remove the filter mechanism through the opening at the top of tank 1 for deep cleaning. The cleaning process will not affect the continuous use of the sewage treatment tank.
