Cleaning sub-station with chemicals pre-allocation function

Abstract

The patent discloses a cleaning sub-station with a chemicals pre-allocation function and relates to cleaning devices. The cleaning sub-station with the chemicals pre-allocation function comprises a shell, a pressure adjusting valve, and a mixing module; a high-pressure water passage is arranged in the mixing module; the mixing module is also provided with a compressed air inlet, a foaming agent inlet and a disinfectant inlet, the compressed air inlet is connected with a first valve, the foaming agent inlet is connected with a second valve, the disinfectant inlet is connected with a third valve, and the incoming water end of the high-pressure water passage is connected with a fourth valve; the mixing module is provided with an adjusting unit, the adjusting unit is provided with at least three stations; when the adjusting unit switches to the first station, only the first valve and the second valve are opened; when the adjusting unit switches to the second station, only the third valve is opened; when the adjusting unit switches to the third station, only the fourth valve is opened; compressed air is fed into the compressed air inlet via the pressure adjusting valve; the foaming agent inlet and the disinfectant inlet are connected with a chemicals pre-allocation station respectively via pipelines. The cleaning sub-station with the chemicals pre-allocation function allows switching of high-pressure water flushing, foam flushing and disinfecting flushing.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a chemical pre-mixed cleaning substation. Background technique [0002] High-pressure cleaning equipment is widely used in people's lives as a cleaning tool, usually used to wash walls, wash cars and other equipment. It uses a power device to make the high-pressure delivery pump generate high-pressure water to wash the surface of the object, which can remove the dirt and wash it away. Go to achieve the purpose of cleaning the surface of the object. [0003] The cleaning of some equipment usually includes multiple cleaning processes, such as foam rinsing, disinfectant rinsing and clean water rinsing; clean water rinsing can be directly produced by the delivery pump with high-pressure water for rinsing; while foam rinsing and disinfectant rinsing require high-pressure water and foam agent and Mixing of disinfectant solution; the existing high-pressure water is mixed with foam agent and disinfe...

AI Technical Summary

Problems solved by technology

But now the mixing of high-pressure water and foam agent or disinfectant is usually carried out with two Venturi tubes, so in the process of disinfecting flushing and foam flushing, it is usually necessary to constantly replace the two pipes, which brings inconvenience to cleaning

[0004] In order to solve the problem of inconvenient switching between disinfection flushing, foam flushing and clean water flushing, our company has developed a dual-channel sub-station cleaning device, which integrates the foam agent suction port and disinfectant liquid suction port on the same venturi tube, and sets The switch module is installed, and the foam agent suction port and the disinfectant liquid suction port can be connected to the Venturi tube respectively by adjusting the switch module, so that the disinfection cleaning, foam flushing and water flushing can be completed through the same Venturi tube through the switching module

However, since the dual-channel sub-station cleaning device relies on high-pressure water to generate a siphon, the foam agent and disinfectant are sucked into the Venturi tube and mixed with water, so chemicals such as foam agent and disinfectant enter the module without pressure in the natural state; and Venturi tube can produce limited suction and cannot realize the long-distance delivery of chemicals without pressure. Therefore, each dual-channel sub-station cleaning device needs to be equipped with a separate chemical storage device to shorten the delivery of chemicals to the foam. The distance between the suction port of the agent and the suction port of the disinfectant solution is used to achieve the purpose of mixing the foam agent and disinfectant with water

When several dual-channel sub-station cleaning devices are required to work simultaneously, it is not possible to supply foam and disinfectant to each dual-channel sub-station cleaning device through a unified chemical storage device, so it is not convenient for chemical storage and distribution
