Further, the overflow weir component comprises a first-level overflow weir and a second-level overflow weir from inside to outside in sequence, and the height of the first-level overflow weir is consistent with the height of the liquid level in the tank body.

Furthermore, the overflow weir subassembly is equipped with the filter screen in the backup pad from the near one end of play pipe wall, the tiny filter residue of filtration that can be further, keeps apart tiny suspended solid.

Furthermore, the height of the filter screen is higher than that of the overflow weir component, so that filter residues can be better isolated.

Further, the filter screen is equipped with the backwash pipe from the nearly one side of jar wall, be equipped with a plurality of orifices on the backwash pipe, the backwash pipe is connected with the water source, can wash the filter screen, avoids the filter screen to block up the filter screen because the filter residue.

Further, the interval of the jet holes is 500mm, and the diameter of the jet holes is 50 mm.

Furthermore, be equipped with a plurality of triangle props between filter screen and the backup pad for the filter screen can be more stable be connected with the backup pad.

The working principle is as follows: the fermentation tank is characterized in that a first-stage overflow weir and a second-stage overflow weir are designed at the fermentation tank body, massive filter residues can be removed in the water outlet process through the design of the multistage overflow weir, meanwhile, a filter screen is arranged at the second-stage overflow weir to filter fine filter residues, the water outlet of the water outlet is free of suspended matters, meanwhile, a backwashing sprayer is arranged at the filter screen, the sprayer is connected with a water source, the pressure of the sprayer is used in the opposite direction along the water outlet direction, the filter residues blocked on the mesh of the filter screen are washed down, the filter screen is prevented from being blocked, and the water outlet is influenced.

The utility model has the advantages as follows:

1. the utility model discloses simple structure makes through the design of multistage overflow weir to avoid bold filter residue direct discharge in the play water of fermentation cylinder, is equipped with the filter screen simultaneously at the afterbody of overflow weir and makes and further filter little filter residue, keeps apart little suspended solid, and the effectual pollution scheduling problem that leads to the environment of having avoided a large amount of filter residues at the direct discharge of drainage in-process.

2. The filter screen is equipped with the back flush pipe from the nearly one side of jar wall, be equipped with a plurality of orifices on the back flush pipe, the back flush pipe is connected with the water source, can wash the filter screen, avoids the filter screen because the filter residue plugs up the filter screen.

3. The utility model discloses the filter screen is equipped with the back flush pipe from the nearly one side of jar wall, be equipped with a plurality of orifices on the back flush pipe, the back flush pipe is connected with the water source, can wash the filter screen, avoids the filter screen because the filter residue plugs up the filter screen, is equipped with a plurality of three angular supports between filter screen and the backup pad for the filter screen can be more stable be connected with the backup pad.
