The scum removal device 1 of the sewage treatment tank comprises: a scum collecting box 10, a first support member 30, a second support member 40 and a scum discharge pump 50.
[0026] The slag box 10 can be a metal part. The cross-section of the slag box 10 can be circular, elliptical, polygonal, etc., and the structure of the slag box 10 is not specifically limited. The top of the slag box 10 is provided with an opening of a certain width, namely the slag inlet 13, and the slag inlet 13 can be arranged along the extension direction of the slag box 10. In one embodiment, the length of the slag inlet 13 is close to the length of the slag box 10. The bottom of the slag box 10 is provided with a slag outlet, and the slag in the sewage treatment tank 2 can enter the slag box 10 through the slag inlet 13, and the collected slag can be discharged through the slag outlet. During use, the slag inlet 13 is basically level with the water surface, which is convenient for effectively collecting the slag on the horizontal surface in the sewage treatment tank 2.
[0027] The first support member 30 and the second support member 40 are respectively arranged at opposite ends of the slag box 10. The bottom of the first support member 30 and the bottom of the second support member 40 are respectively rotatably connected to the opposite ends of the slag box 10, which helps to adjust the angle of the slag inlet 13 of the slag box 10. The flexibility is good and helps to clean the slag under different working conditions. The top of the first support member 30 and the top of the second support member 40 are respectively used to be fixedly connected to the sewage treatment tank to fix the slag box 10 in the sewage treatment tank. Optionally, the first support member 30 and the second support member 40 are respectively arranged vertically with the slag box 10, such as Figure 3 and Figure 4 The first support member 30 and the second support member 40 of the embodiment of the present invention are both telescopic members, and the lengths of the first support member 30 and the second support member 40 can be adjusted according to the water level change in the sewage treatment tank and the cleaning requirements, so as to adjust the position of the slag collecting box 10, which is helpful to effectively remove the scum. Figure 3 and Figure 4 As shown, the first support member 30 and the second support member 40 are at a first length, as shown in FIG. Figure 7 and Figure 8 As shown, the first support member 30 and the second support member 40 are at a first length and a second length, and the first length is greater than the second length.
[0028] It should be noted that, in the embodiment of the present invention, the length of the first support member 30 and the second support member 40 can be adjusted to lift the slag collecting box 10 and regularly clean the slag collecting box 10 to keep it in good working condition and facilitate maintenance.
[0029] Further, in order to effectively remove the scum in the slag box 10 from the sewage pool. In the embodiment of the present invention, a slag discharge pump 50 is provided at the outlet of the slag box 10. Specifically, the inlet of the slag discharge pump 50 is connected to the slag outlet through the pipeline 120, and the outlet of the slag discharge pump 50 is used to communicate with the collection device. By using the suction effect of the slag discharge pump 50, the slag in the sewage treatment pool 2 enters the slag box 10 and is discharged into the collection device through the pipeline 120. The embodiment of the present invention uses a slag discharge pump 50 to quickly discharge scum, is less restricted by environmental conditions, and is easy to operate. It should be noted that the pipeline 120 is a hose, which is convenient for adjusting the position of the pipeline 120. The slag discharge pump 50 can be a non-clogging anti-entanglement submersible mud pump. The two ends of the pipeline 120 are respectively connected to the slag outlet and the slag discharge pump 50 by threads to prevent the pipeline 120 from detaching during the slag discharge process.
[0030] The scum removing device 1 for a sewage treatment tank provided in an embodiment of the present invention fixes a scum box 10 in a sewage treatment tank by means of a first support member 30 and a second support member 40, and discharges the scum by means of the suction action of a scum discharge pump 50, so that the cleaning efficiency is high and the operation is convenient. By setting the first support member 30 and the second support member 40 as telescopic members, it is convenient for the user to adjust the position of the scum box 10 based on the water level change in the sewage treatment tank 2 and the cleaning requirements, so as to effectively remove the scum. It is also helpful to regularly clean the scum box 10 for easy maintenance.
[0031] like Figure 5 and Figure 6 As shown, the first support member 30 and the second support member 40 both include: a first support section 41 and a second support section 42. The bottom of the first support section 41 is rotatably connected to the slag collecting box 10.

[0032] In an optional embodiment, the first support segment 41 is slidably connected to the second support segment 42, and under the action of external force, the first support segment 41 can move up and down along the second support segment 42. It should be noted that a limiting structure is provided between the second support segment 42 and the first support segment 41. After the second support segment 42 moves to the target position, the limiting structure can limit the position of the first support segment 41 and the second support segment 42 to prevent the second support segment 42 from moving at will. For example, a groove is provided on the side wall of the first support segment 41, and the protrusion is provided in the groove through an elastic member, that is, the protrusion can be embedded in the groove under the action of external force; a limiting hole is provided on the second support segment 42, and under the action of external force, the protrusion is embedded in the groove. When the limiting hole of the second support segment 42 corresponds to the protrusion, the protrusion pops out and is embedded in the limiting groove, thereby limiting the position of the second support segment 42. It should be noted that there are multiple limiting holes and protrusions. During the movement, the protrusion can be embedded in the groove manually to prevent the protrusion from affecting the movement of the second support segment 42.
[0033] The first support member 30 and the second support member 40 in the embodiment of the present invention further include a sleeve 43, and the first support section 41 and the second support section 42 are connected through the sleeve 43.

The first support section 41 is slidably connected to the inner wall of the sleeve 43, and the first support section 41 can move along the extension direction of the sleeve 43 (the extension direction of the second support section 42) to adjust the length of the first support member 30 and the second support member 40. When the length is shortened, the first support section 41 can be stored in the sleeve 43. It should be noted that a fixing member is provided on the sleeve 43 to limit the position of the first support section 41. For example, a first fixing hole is provided on the side wall of the sleeve 43, and a second fixing hole is provided on the first support section 41. When the second support section 42 moves to the target position, the first fixing hole and the second fixing hole correspond, and the fixing member is sequentially penetrated through the first fixing hole and the second fixing hole, thereby limiting the position of the first support section 41. In another embodiment, the first supporting section 41 is also a telescopic structure, and the top of the first supporting section 41 is fixed in the sleeve 43 .
[0034] In order to effectively adjust the direction of the slag inlet 13 of the slag collecting box 10, the embodiment of the present invention drives the slag collecting box 10 to rotate through a rotating assembly.
