Toilet paper machine sealing water recovery unit

Technical Field

The utility model relates to the technical field of papermaking equipment, and particularly discloses a sealing water recovery device of a toilet paper machine.

Background

The existing paper making process can be generally made into paper after working procedures of pulping, jordaning, pulp flowing, papermaking, squeezing, drying, calendering and the like. The paper making equipment in the process needs to use sealing water to cool and cool the machinery, for example, a vacuum water washing tank arranged on the paper making machine is essentially a plurality of vacuum pumps, the sealing water in the vacuum pumps is often used as waste water to be directly discharged after being used for a period of time, so that the environment is polluted, the waste of water resources is also caused, and extra fresh water needs to be supplemented as the sealing water to ensure the normal use of the paper making equipment.

In order to solve the above problems, the prior art discloses chinese patents with publication numbers: CN209900842U, a spin filter, including being the tubbiness container, container one end opening other end is equipped with clear water discharge port and row cinder notch, and the opening part is connected with the main inlet tube that the external diameter is less than row cinder notch internal diameter through supporting mechanism, main inlet tube one end is worn out row cinder notch and is formed the end of intaking, main inlet tube outside is equipped with the spin filter that can relatively main inlet tube axial pivoted between supporting mechanism and the end of intaking, this scheme will be followed intake end and got into the sewage in the container and filtered the clear water and pass through clear water discharge port discharge container, waste residue through row cinder notch discharge container, this scheme not only can be used for filtering papermaking plain water also can be used for the filtration etc. of vacuum pump sealing water, and the filter cloth is owing to receiving to erode, can keep filtering capability for a long time. However, the following problems still exist in this solution: the water pressure of the sewage entering the filtering device can not be adjusted according to the flow of the sewage, so that when the water pressure of the sewage is too small, the sewage can not be flushed onto the filtering body, and the sewage is discharged out of the filter without being filtered; because the impurity that sealed water filters is very little, the mesh of filtering the body is very little, if sewage water pressure undersize, the dynamics of assaulting on filtering the body is not enough, and sewage can flow out the filter along the filter to lead to the poor problem of filter effect.

SUMMERY OF THE UTILITY MODEL
