Also, the discharge pipe 102 and the water level sensor 103 are provided on the cleaning flange 101 to facilitate disassembly inspection and replacement.

In addition, in some embodiments of the present invention, a float type water level alarm is provided in the tank 100 to give an alarm when the water level reaches a preset value. The float type water level alarm and the water level sensor 103 may be an integrated structure.

Referring to fig. 2 and 3, in an alternative embodiment of the present invention, the cleaning flange 101 includes a groove region 106 and a flange rim 107, the flange rim 107 is disposed at an outer edge of the groove region 106, the flange rim 107 is disposed at an inner side of the tank body 100, the groove region 106 faces the inner side of the tank body 100, and a bottom of the tank body 100 is higher than the groove region 106, wherein the discharge pipe 102 and the water level sensor 103 are disposed at the groove region 106.

In other words, the recessed area 106 of the cleaning flange 101 is lower than the bottom of the tank 100, so that water can flow out of the discharge pipe 102 more smoothly. The flange rim 107 is attached to the bottom of the tank 100 to facilitate the fixing of the cleaning flange 101, and since the cleaning flange 101 bears the weight of the discharge pipe 102, the water level sensor 103 and the suction pipe 104, the load-bearing capacity of the cleaning flange 101 can be increased by the flange rim 107.

When the cleaning flange 101 is removed in the oil-free state of the tank 100, the cleaning flange 101 is placed in the tank 100 after the bolts for cleaning the flange 101 are removed from the bottom of the tank 100, and then the discharge pipe 102 is washed and cleaned in the tank 100. Alternatively, a flange having a large diameter is provided on the upper portion of the tank 100, and the cleaning flange 101 is taken out from the upper portion of the tank 100 and cleaned.
