When the cleaning device is used, the cleaning device can be operated without professional staff (as long as a cleaner has simple electrical and chemical knowledge and has the consciousness of electric shock prevention, scald prevention and corrosion prevention).
Impurities, scales and other substances generated after the equipment is used for a long time need to be cleaned by adopting an acid solution. In this embodiment, the cleaning liquid is preferably an oxalic acid solution or a phosphoric acid solution, and since oxalic acid/phosphoric acid has weak acidity and reducing property, the effect of cleaning dirt is very remarkable. Since the acidic solvent (e.g., oxalic acid/phosphoric acid) is slowly dissolved at normal temperature, and thus the cleaning solution needs to be heated, as shown in fig. 3, the cleaning apparatus further includes a heater 700, and a heater 400 is disposed at a bottom region of the solution preparation tank 100 for heating the cleaning solution, thereby accelerating the solubility of oxalic acid/phosphoric acid in water. The bottom area indicates that the heater 700 may be provided at the bottom of the liquid distribution tank 100, or may be provided at an area of the side surface near the bottom. The heater 700 is, for example, a heating rod, and the heating rod is preferably two heating rods, the two heating rods are mounted on the side surface of the liquid distribution box 100 near the bottom surface and are arranged parallel to the bottom surface, one end of the heating mounting seat is connected to the heating rod body, and the other end of the heating mounting seat is connected to the heater power cord.

The heater 700 may be provided according to the prior art by one skilled in the art. In the present embodiment, the heating temperature of the heater 700 is set to 50 degrees, and the maximum is not more than 70 degrees. On one hand, oxalic acid/phosphoric acid dissolution can be accelerated, and on the other hand, the temperature of the cleaning liquid cannot be too high to scald a cleaner or a worker. In other embodiments, other temperatures may be set, such as 40 degrees or 45 degrees. It should be noted that when the heater 700 stops heating, the cleaning liquid cannot be heated automatically after the temperature of the cleaning liquid is reduced, so that on one hand, the heater is prevented from heating automatically after cleaning is completed, which causes a safety problem, and on the other hand, unnecessary loss caused by re-heating is prevented, thereby saving energy. Of course, the heater 700 may be powered off manually or automatically, for example, after the temperature of the cleaning solution is determined by the cleaner, the power is turned off manually; for another example, the heater 700 may be automatically powered off when the temperature is higher than the maximum preset temperature.
Preferably, the temperature of the cleaning liquid is determined by a cleaner, the cleaner or other workers are prevented from being scalded by overhigh temperature, and the solubility of the oxalic acid/phosphoric acid is prevented from being influenced by overlow temperature. Referring to fig. 4, the cleaning apparatus further includes a temperature sensor 900 (in fig. 4, an operation schematic diagram of the temperature sensor 900 is shown, and an actual connection relationship and a position relationship are not shown), which is disposed in the liquid distribution box 100 and is used for sensing a temperature in the liquid distribution box 100. Preferably, the temperature sensor 900 is disposed near the heater 700 and parallel to the heating rod, the temperature sensor 900 is disposed perpendicular to a sidewall of the liquid distribution box 100, a detection end thereof extends into the sidewall of the liquid distribution box 100 for detecting an internal temperature, and a display end thereof extends out of the sidewall of the liquid distribution box 100 for a washer to view a temperature. In other embodiments, the temperature sensor 900 may also be a thermometer, which is attached to the inner wall of the liquid distribution box 100, and the height of the detection end is lower than the liquid level that the cleaning liquid can cover. Of course, other temperature sensing devices can be provided by those skilled in the art according to the prior art.
Further, in the process of cleaning the equipment, the cleaning solution needs to be in an acidic condition to have a cleaning effect, so that the acidity and alkalinity of the cleaning solution need to be detected, and the detection indexes are as follows: (1) detecting the pH value of the prepared oxalic acid/phosphoric acid solution, and when the pH value is 2-3, meeting the requirement of the pH value of the cleaning solution, and starting cleaning; (2) in the cleaning process, the acidity of the cleaning solution is weakened, and when the pH reaches 5-6, oxalic acid/phosphoric acid needs to be added again to restore the pH to 2-3; (3) when the pH of the cleaning solution is maintained at 2-3 for 30 minutes without significant change, it is indicated that the cleaning is completed and the cleaning effect is achieved. The cleaning device preferably further comprises a pH detection unit for detecting the pH of the cleaning liquid. The pH detection unit is, for example, a pH indicator or a pH test paper. When the pH test paper is used, a cleaner collects the cleaning solution to detect the pH before, during and after the cleaning under the requirements of the above three indexes, specifically, referring to fig. 1, a dry glass rod or a rubber dropper is used to enter the upper surface of the liquid level from the upper end opening 110, and a drop of the cleaning solution is dipped or sucked and then dropped in the middle of the pH, and the acidity and alkalinity of the cleaning solution is determined according to the comparison between the color change of the pH test paper and a standard colorimetric card. When using a pH indicator for detection, several drops of the pH indicator are added to the wash solution from the upper opening 110, different indicators will change color depending on the pH value, and the pH range is determined depending on the indicator color. Specifically, the pH indicator, such as litmus sample, changes to red when exposed to acid and changes to blue when exposed to alkali, thereby determining the approximate range of pH, and those skilled in the art can determine the degree of acidity or alkalinity according to the color change of litmus sample.
In order to facilitate observation of the liquid level of the cleaning liquid in the liquid preparation tank 100, and during preparation of the cleaning liquid, the amount of the liquid (such as water) can be quantitatively determined, so that the cleaning liquid can be conveniently prepared, for example, 50L of water is poured, and 2.5L of phosphoric acid is poured by calculation; alternatively, 90L of water and then 4.5L of phosphoric acid, measured in a measuring cup, may be added to the tank 100, the volume of water added to the tank 100 being determined. Preferably, as shown in fig. 1 to 3, the liquid dispensing tank 100 includes a scale indicating member 150 for displaying the liquid level of the cleaning liquid and dispensing the cleaning liquid. Specifically, the scale indication component 150 is made of a transparent material and is attached to the side surface of the liquid distribution box 100, so that a cleaner can observe the liquid level of the cleaning liquid outside the liquid distribution box 100, and meanwhile, the transparent material or the transparent material is provided with a liquid level scale 151, so that the liquid level information of the cleaning liquid can be determined. Wherein, the liquid level scale 151 is calculated by the volume in the liquid preparation tank.
