The detergent delivery pipe 210 is sequentially connected with a valve 220 and a metering pump 230, and the tap water delivery pipe 310 is connected with a first flow regulating valve 320.
The first liquid level sensor 110, the concentration sensor 120 and the stirring device 130 are arranged in the proportioning barrel 1, and the second liquid level sensor 240 is arranged in the detergent storage tank 2.
The external side wall of the detergent storage tank 2 is provided with a jacket 250, and a temperature sensor 260 is arranged in the detergent storage tank 2.
The heating medium inlet of the jacket 250 is provided with a second flow rate adjustment valve 2501.
The detergent proportioning machine is further provided with a controller 4, and the controller 4 is respectively connected with the first liquid level sensor 110, the concentration sensor 120, the stirring device 130, the second liquid level sensor 240, the valve 220, the metering pump 230, the second flow regulating valve 2501, the temperature sensor 260, the first flow regulating valve 320 and the alarm 5.
Specifically, when a vehicle is cleaned at a station, concentrated detergent and tap water are required to be mixed and proportioned according to a proportion to obtain a detergent aqueous solution, and then a pressure pump is started to spray the detergent aqueous solution to the vehicle to be cleaned through one or more detergent spray pipes, so that the vehicle is cleaned. The mixing of the detergent with tap water makes the detergent generate abundant foam, which is convenient for removing stains on vehicles, and the mixing proportion is determined by the cleaning capability of the detergent.
In the process of cleaning the vehicle, the power supply is turned on, the controller 4 opens the valve 220 on the detergent conveying pipeline 210, the metering pump 230 and the first flow regulating valve 320 on the tap water conveying pipeline 310, the detergent and the tap water are conveyed to the proportioning barrel 1, and the stirring device 130 is turned on for stirring, so that the detergent and the tap water are uniformly mixed, abundant foam is conveniently generated, and the cleaning of stains is facilitated. Whether the detergent is input into the proportioning barrel 1 or not is controlled by controlling the switch of the valve 220, the metering pump 230 is used for pumping the detergent in the detergent storage tank 2 to the proportioning barrel 1 through the detergent conveying pipeline 210 after the valve 220 is opened, meanwhile, the flow of the detergent can be adjusted, the metering pump 230 can improve the conveying capacity of the detergent, is suitable for the detergents with different viscosities, and is favorable for accurate proportioning of the detergent and water. By communicating the tap water conveying pipeline 310 with the tap water interface 3, the first flow regulating valve 320 is used for controlling the start and stop of the tap water and regulating the flow rate of the tap water, and the concentration of the detergent aqueous solution is controlled by the metering pump 230 and the first flow regulating valve 320. Meanwhile, the concentration of the detergent aqueous solution is displayed in real time by the concentration sensor 120, and a concentration signal is transmitted to the controller 4, and the controller 4 determines the adjustment of the flow rate of the metering pump 230 or the first flow rate adjustment valve 320 according to the received concentration signal.

If the detergent proportioning machine works in a low-temperature environment, the detergent is not beneficial to conveying due to temperature reduction and viscosity increase, at the moment, the metering pump 230 is adopted to pump the detergent into the proportioning barrel 1, the operating load of the metering pump 230 is increased due to the fact that the detergent is high in viscosity, and the energy consumption of the metering pump 230 is increased due to long-time operation, so that the temperature of the body of the metering pump 230 is increased, and the service life is shortened. Therefore, the detergent in the detergent tank 2 is heated by providing the jacket 250 on the outer sidewall of the detergent tank 2, providing the second flow rate adjustment valve 2501 at the heating medium inlet of the jacket 250, and adjusting the flow rate of the heating medium entering the jacket 250 by the second flow rate adjustment valve 2501. The temperature rise enables the viscosity of the detergent to be reduced, the mobility of the detergent to be larger, the adhesion and adhesion of the detergent to conveying equipment in the transportation process are reduced, the waste is reduced, and the cost is reduced. Meanwhile, the transportation load of the metering pump 230 is reduced, the power consumption is reduced, the measured data of the metering pump 230 is more accurate, and the ratio of the detergent to the water is more accurate. The heating medium of jacket 250 is water. The temperature sensor 260 is disposed in the detergent storage tank 2, and is configured to detect the temperature of the detergent in the detergent storage tank 2 in real time, and transmit a temperature signal to the controller 4, and the controller 4 determines the opening degree of the second flow rate adjustment valve 2501 according to a difference between the received temperature signal and a set detergent temperature, and then adjusts the temperature of the detergent in the detergent storage tank 2. Wherein the set detergent temperature is determined according to the viscosity temperature characteristics of the purchased detergent. By the arrangement, the detergent proportioning machine can be suitable for environments with wide temperature change range, such as winter. The applied detergent proportioning machine is not limited to the proportion of the detergent used in the car washing station to the water, and can also be suitable for the proportion of other liquid to the water, such as the proportion of clothes detergent, restaurant detergent to the water, and the proportion of nonvolatile liquid such as cutting fluid, petroleum and the like to the water in the industry.

Through setting up the measuring pump, can improve the conveying capacity of detergent, be applicable to the ratio of the detergent aqueous solution of different viscosities under the different temperatures. The concentration of the detergent is controlled through the metering pump and the first flow regulating valve, the concentration of the detergent is displayed in real time through the concentration sensor, the metering pump and the first flow regulating valve are controlled through the controller, the flow regulation of the metering pump and the first flow regulating valve is facilitated, the accurate proportioning of the detergent and water is facilitated, the foam is richer, and the cleaning of the detergent to stains is facilitated. The alarm is arranged, so that workers can supplement the detergent in time, and the continuous operation of the detergent proportioning machine is ensured. The jacket is arranged on the outer side wall of the detergent storage tank, the opening degree of the second flow regulating valve is controlled through the controller, the temperature of the detergent in the detergent storage tank is further regulated, the viscosity of the detergent is reduced, adhesion of the detergent and conveying equipment in the transportation process is reduced, waste is reduced, the power consumption of the metering pump is reduced, and the cost is reduced. The detergent proportioning machine of this application can be applicable to the environment of different temperatures.
Fig. 2 is a schematic structural diagram of a detergent proportioning machine for a washing station according to another embodiment of the present application, and as shown in fig. 2, a heating coil 2101 is optionally coiled on the outside of the detergent conveying pipeline 210.
Specifically, during the transportation process of the detergent, the temperature decrease of the detergent in the detergent transportation pipeline 210 has little influence on the viscosity of the detergent, so that the energy consumption of the metering pump 230 does not change significantly, and a heat preservation device is not required. However, if the distance between the proportioning barrel 1 and the detergent storage tank 2 is long and the ambient temperature is low, that is, the temperature of the detergent in the detergent conveying pipeline 210 is too low, which results in a large increase in the viscosity of the detergent and an increase in the energy consumption of the metering pump 230, the heating coil 2101 needs to be coiled outside the detergent conveying pipeline 210 to convey the detergent in a heat preservation manner, so that the conveying efficiency is improved, and the accuracy of the proportioning of the detergent and the water is further improved. The heating medium in the heating coil 2101 is the same as the heating medium in the jacket 250.

Specifically, the third flow rate adjustment valve 2102 is used to adjust the flow rate of the heating medium entering the heating coil 2101, and the degree of opening of the third flow rate adjustment valve 2102 is controlled by the controller 4 so that the flow rate of the heating medium entering the heating coil 2101 is equal to the flow rate of the heating medium entering the jacket 250, ensuring that the viscosity of the detergent does not decrease.
Optionally, the tap water conveying pipeline 310 is further connected to a spare tap water storage tank 6 through a spare tap water pipeline 330, a fourth flow regulating valve 3301 is disposed on the spare tap water pipeline 330, and the fourth flow regulating valve 3301 is disposed in parallel with the first flow regulating valve 320.
The fourth flow rate adjustment valve 3301 is connected to the controller 4.
Specifically, when the controller 4 detects that the first flow regulating valve 320 is equal to 0, the controller 4 closes the first flow regulating valve 320 and opens the fourth flow regulating valve 3301 on the spare tap water pipeline 330, so that the detergent proportioning machine stops working when the tap water is cut off, the proportioning needs to be manually performed, and the accuracy of manual operation is poor. The automatic tap water source switching device is more automatic, reduces manual input and ensures the continuous operation of the detergent proportioning machine through the controller 4.
Fig. 3 is a schematic structural diagram of a detergent proportioning machine for a washing station according to still another embodiment of the present disclosure, and as shown in fig. 3, optionally, a filter 340 is connected to the tap water conveying pipeline 310, and the filter 340 is respectively connected in series with the first flow regulating valve 320 and the fourth flow regulating valve 3301.
Specifically, the tap water conveying pipeline 310 is connected with a filter 340 for filtering impurities in the tap water from the tap water connector 3 and the tap water storage tank 6, so as to prevent the impurities from blocking the detergent water solution outlet of the proportioning barrel 1 or causing adverse effects on the operation of the proportioning barrel 1.
Optionally, the stirring device 130 includes a motor 1301, a stirring shaft 1302, and a stirring paddle 1303 connected in sequence, and the motor 1301 is connected to the controller 4.
The stirring paddles 1303 are arranged at intervals along the vertical direction.
Specifically, the stirring device 130 makes the detergent and the tap water mixed more uniformly, enhancing the cleaning effect of the detergent. The stirring paddles 1303 are arranged at intervals along the vertical direction, so that the mixture of the detergent and the water can be ensured to passively move along with the rotation of the stirring paddles 1303 to achieve the effect of full mixing when the capacity of the proportioning barrel 1 is large or the diameter of the proportioning barrel is large, and the phenomenon that the stirring part of a large amount of liquid is static is prevented.
Optionally, one end of the detergent conveying pipeline 210 extending into the proportioning barrel 1 is 10-20cm away from the side wall of the proportioning barrel 1.
Specifically, the arrangement avoids the detergent from hanging on the wall after entering the proportioning barrel 1, so that the amount of the detergent mixed with tap water is reduced, the data measured by the concentration sensor 120 is small, and the controller 4 controls the metering pump 230, so that the flow of the detergent conveyed to the proportioning barrel 1 is increased, the concentration of the detergent aqueous solution is large, and the detergent is wasted. Furthermore, a guide plate can be arranged at the detergent inlet inside the proportioning barrel 1, so that the detergent entering the proportioning barrel 1 is directly mixed with tap water, and the phenomenon of wall hanging is avoided.
