When the scheme of the embodiment is used specifically, the flow is as follows:
at the beginning, the viscous liquid storage end control valve 21 and the viscous liquid use end control valve 11 are both in a closed state, the pipe main valve 40 is in a closed state, the pump 60 and the main pipe 30 are in a communication state, the main pipe 30 and the flush pipe 80 are in a disconnection state, and the pipe main valve 40 is in a disconnection state.
When a certain device at the use end sends a signal that a certain viscous liquid at the liquid storage end is required to be stored, the corresponding viscous liquid use end control valve 11 and the corresponding viscous liquid storage end control valve 21 are opened, the pump 60 is started to work, water in the pipeline is discharged, the viscous liquid enters the pipeline, and when the set amount is reached, the pump 60 is stopped; then the control valve 21 of the viscous liquid storage end is closed, the reversing valve 50 acts at the same time, the pump 60 is disconnected from the main pipe 30, the main pipe 30 is communicated with the flushing pipe 80, the main pipe 40 of the pipe is opened, water enters through the flushing pipe 80, and the liquid in the whole pipe is flushed into the equipment corresponding to the use end through the reversing valve 50, the main pipe 30, the branch pipe 32 of the liquid storage end, the main pipe 40 of the pipe and the branch pipe 31 of the use end, so that feeding and conveying of the required viscous liquid are completed, and then all the valves are reset to the initial state.
When the embodiment is specifically applied to the field of laundry detergent conveying, the viscous liquid is various laundry detergents, the viscous liquid using equipment is a washing machine, when a certain washing machine sends a signal and needs a certain laundry detergent, the corresponding washing machine valve is opened, the corresponding laundry detergent valve is opened, and the pump starts to work. The pump pumps the laundry detergent into the pipeline or the liquid storage tank, after the laundry detergent reaches a set amount, the pump stops, the laundry detergent valve is closed, the reversing valve acts, the port 2 is communicated with the port 3, and the pipeline main valve is opened. Water enters the main pipeline or the liquid storage tank through the flushing pipe through the two three-way valve ports 3 and the port 2, and liquid in the main pipeline or the liquid storage tank and the whole pipeline is flushed into the corresponding washing machine, so that feeding and conveying of the laundry detergent are completed. After the actions are finished, the main valve of the pipeline is automatically closed, the reversing valve is automatically reset, and the port 1 is communicated with the port 2. Adopt this scheme to carry out the transport of laundry liquid, compare in current mode, can realize the quick transport of laundry liquid, the technological effect of accurate quick feeding. The present laundry detergent delivery and dispensing method is described as follows:
in the actual operation of the laundry, because different laundry detergents need to be filled into different washing machines through pipelines at different time intervals, the laundry detergents are viscous and are directly pumped by pumps, the resistance of the viscous liquid to the pumps is very large, the efficiency is low, and the laundry detergents cannot be quickly added into the washing machines, one currently adopted conveying mode is shown in fig. 9, a valve end 91 of the washing machine is provided with a plurality of washing machines and is connected with a laundry detergent valve end 92 through a main pipeline, each laundry detergent at the laundry detergent valve end 92 is independently connected with a pump and a check valve 95, all outlets of the laundry detergent valve end 92 are connected with a laundry detergent end conveying pipeline, one end of the laundry detergent end conveying pipeline is connected with the main pipeline, the other end of the laundry detergent end conveying pipeline is connected with a main valve 93, and the main valve 93 is connected with a flushing port 94. When a certain washing machine needs a certain laundry detergent, the pump at the corresponding laundry detergent end and the corresponding washing machine valve are opened, the laundry detergent is pumped into the pipeline by the pump connected with the corresponding laundry detergent, then the main valve is opened, and water flushes the laundry detergent in the pipeline into the needed washing machine through the flushing port. The conveying mode has the problems that the efficiency of pumping the laundry detergent is low, the number of required pumps is large, one laundry detergent needs one pump, and the cost is high.
Another way of conveying the laundry detergent is shown in fig. 10, where a valve end 91 of a washing machine is provided with a plurality of washing machines, and is connected to a valve end 92 of the laundry detergent through a main pipe, a pump is provided on the main pipe, all outlets of the valve end 92 of the laundry detergent are connected to a conveying pipeline of the laundry detergent, one end of the conveying pipeline of the valve end of the laundry detergent is connected to the main pipe, the other end of the conveying pipeline of the valve end of the laundry detergent is connected to a main valve 93, and the main valve 93 is connected to a flushing port 94.

When the method is adopted for conveying, the pump pumps water and the laundry detergent, and the pumping amount is different because the viscosity of the water is different from that of the laundry detergent, and the flow rates of the water and the laundry detergent are different during pumping, so that the conveying method cannot determine the amount of the pumped water and the laundry detergent, and the problem of inaccurate amount of the laundry detergent conveyed into the washing machine can occur; meanwhile, the laundry detergent has large resistance and low efficiency when passing through the pump, and when the laundry detergent is flushed at last, water and the laundry detergent need to pass through the pump body, and the liquid is subjected to resistance when advancing, so that the efficiency is lowered.
When the viscous liquid conveying mode in the application is adopted for conveying and distributing the laundry detergent, when the laundry detergent needs to be conveyed, the pump only pumps water, and the laundry detergent is not pumped, so that the pumping efficiency can be improved; the pump only pumps water, so that the pumped water quantity can be accurately controlled, and the quantity of the laundry detergent pumped into the pipeline can be accurately controlled; meanwhile, when the liquid in the pipeline is sent to the washing machine by flushing water at last, the liquid in the pipeline directly enters the washing machine through the pipeline without passing through a pump, so that the resistance is reduced, and the flushing efficiency is high.
