Drainage control method for dyeing process

Abstract

The invention discloses a drainage control method for a dyeing process. The method comprises the steps that all draining water in a main tank runs through a measuring water tank in the dyeing process;when the main tank drainage function is implemented in the dyeing process, a shaving power drainage valve is opened to pump up water to the measuring drainage tank, after the water is drained to a set water level, the shaving power drainage is switched off, and a horizontal pump is switched on to drain residual liquid into the measuring drainage tank through a power overflow drainage valve; afterwater in the main tank is drained off, the drainage valve is opened to drain off water in the measuring drainage tank; water flows into the main tank from a preparation tank, before the water inflowquantity reaches a set value, a first water inflow valve is opened, a second water inflow valve is closed, and when the water inflow quantity reaches the set value, the first water inflow valve is closed, and the second water inflow valve is opened to ensure the water inflow precision. According to the drainage control method for the dyeing process, all the draining water in the main tank must runthrough the measuring drainage tank in the dyeing process, so that the precision of the liquor ratio is ensured, the total drainage quantity is convenient to calculate, and the measuring drainage tank is used for precisely calculating the water absorption rate.

Description

technical field [0001] The invention relates to the field of dyeing, in particular to a drainage control method for dyeing process. Background technique [0002] At present, the drainage control in the dyeing process generally has the following deficiencies: the traditional statistical method of drainage volume is to simulate and count the drainage volume, and the statistical data is not accurate; the drainage of the drainage tank and the water intake of the main tank cannot be carried out at the same time, and it is impossible to achieve water intake while draining; Accurately calculate the water absorption rate; water is only added to the reserve tank when it is used, which prolongs the dyeing process cycle and reduces the process efficiency; when the reserve tank is not prepared with enough water, there is no reminder, which affects the progress of the process; the displacement of each time cannot be Visual display is not convenient for later problem analysis.
