Example 1
As shown in fig. 1, a washing process of a 16-bin counter-current rinsing tunnel type washing machine comprises the following steps:
(1) Loading by a loader: the loader adopts a weighing conveyer belt and a climbing conveyer belt. Workers put linen to be washed into the climbing conveyor belt (the minimum weight of the linen is 35KG, and the maximum weight of the linen does not exceed a set value: generally within 60 KG). When the time of a washing cycle of the tunnel washing machine is up, the weighing conveyer belt and the climbing conveyer belt run after the warehouse is reversed and ended. The weighing conveyer belt is used for weighing the linen, and the climbing conveyer belt is used for conveying the weighed linen to an inlet of the tunnel type washing machine (a photoelectric sensor at the tail end of the climbing conveyer belt).
(2) Pre-washing: and (3) conveying the linen to the photoelectric sensor at the tail end of the climbing conveyor belt for sensing, and conveying the linen to the pre-washing bin. And (3) starting water adding in a pre-washing bin after a general delay time (such as 20-30 seconds) from the start of the operation of the climbing conveyor belt, wherein water adding in the pre-washing stage can be selected from one or more of a first water tank, a second water tank and raw water, and the water is added in sequence according to the set water adding amount.
Wherein, the water in the first water tank comes from the water discharged from the rinsing bin, the water in the second water tank comes from the water discharged from the neutralization bin and the water in the squeezing water tank, and raw water is normal clear water. In the embodiment, the water in the rinsing bin, the neutralization bin and the squeezing water tank is secondarily utilized in the pre-washing stage, so that the consumption of raw water is greatly reduced.
The pre-washing stage is generally carried out by adding water 4-5.5 times of the weight of the linen: namely, 4L to 5.5L of water is added into one kilogram of linen, and the real-time water adding is set according to the weight of the linen instead of setting the fixed water adding amount, so that the water adding bath ratio is optimized, and the water consumption is reduced.
The pre-washing bin is mainly used for fully mixing dry linen and water, the linen with blood stains is washed clean in the pre-washing bin through material conversion reaction, and the material conversion adding amount in the pre-washing stage is 0.3-2.0 times of the linen weight.
In this embodiment, the number of pre-washing bins is set to two bins, namely 1 bin and 2 bins, and the washing time is 3-6 minutes. Or can be arranged into three bins, namely 1 to 3 bins, and the washing time is 4 to 10 minutes.
(3) And (3) main washing: the main washing bin is used for mainly changing dirty water in the pre-washing bin, and increasing the temperature to provide a factor for cleaning main washing liquid.
After the pre-washing is finished, the pre-washed linen is conveyed into a main washing bin, water and chemical materials are added into the main washing bin for washing, the temperature is heated at 55-80 ℃ in the washing process, and the main washing time is 10-20 minutes.
The main washing bin is 3 bins to 10 bins, and the main washing bin can be set to be 4 bins to 10 bins under special conditions.
