Background
The existing cylinder liner cleaning equipment can carry out batch cleaning on the cylinder liner, cleaning fluid needs to be added in the cylinder liner cleaning process, generally, the concentration of the cleaning fluid is recommended to be blended according to the use instruction when the cylinder liner is cleaned, but the adhesion amounts of solid matters such as carbon deposit, oil sludge and metal chips on the surface of different cylinder liners are different, the required cleaning fluid concentration is also different, if the cleaning fluid is blended according to the same concentration, if greasy dirt on the surface is lighter, the cleaning fluid with lower concentration can be effectively cleaned. Conversely, if the oil is heavy, a higher concentration of cleaning solution may be required for effective removal.
It is also a point that during the cleaning process, the amount of oil stain on the cylinder liner surface is continuously reduced, which results in a cleaning solution having a concentration gradually greater than the required concentration for cleaning the oil stain, and the excessive cleaning solution reacts with the cylinder liner surface, and after a period of reaction, corrosion may occur on the cylinder liner surface.
In summary, if one concentration of cleaning liquid is uniformly used all the time, poor cleaning effect or unnecessary corrosion to the cylinder liner surface may be caused.

On the other hand, the consumption of the cleaning liquid is accurately controlled, so that the waste can be avoided, and the consumption of the cleaning liquid is reduced.

Detailed Description
The present invention will be described in further detail below with reference to examples of the present invention in order to make the objects, technical solutions and advantages of the present invention more apparent. It is to be understood that the specific examples described herein are for purposes of illustration only and are not intended to limit the invention, as the materials, reagents, etc. used in the examples described below are commercially available unless otherwise specified.
The invention provides a continuous cleaning system for cylinder sleeve processing, which is characterized by comprising the following steps of:
S1, placing a batch of cylinder jackets to be cleaned on a conveyer belt according to preset positions, starting the conveyer belt to convey the batch of cylinder jackets into a cleaning chamber, wherein each cylinder jacket is connected with a corresponding spraying device through an independent water pipe, and each spraying device is connected with a water source through a liquid conveying pipe;
Preferably, before the cylinder sleeve is placed on the conveyor belt, the cylinder sleeve is pretreated, and the surface is purged by compressed air to remove large particle impurities, so that the burden of a spraying device is reduced, and the cleaning efficiency is improved;
S2, acquiring a surface image of the cylinder sleeve through an image acquisition device, judging the pollution degree i 0, determining the quantity and the type of surface pollutants according to an energy spectrum analyzer and an image amplification device, and calculating the ratio w 0 of the greasy dirt pollutants in the surface pollutants; wherein, i 0 is 0-5 level, 0 is clean state, 5 is the highest pollution degree state;
w 0 = amount of oil stain/amount of surface contaminants;
Wherein, the pollutants on the surface of the cylinder sleeve comprise solid particles such as greasy dirt, scrap iron dust and the like;
Preferably, an X-ray energy spectrum analyzer is selected to detect the partial surface of the small sample piece in a surface scanning mode, different areas are selected to carry out multiple measurement, and the quantity and the type of surface pollutants are determined according to the components and the appearance characteristics by combining the observation of a super-depth microscope;
after the cleaning liquid and the clean water are mixed in proportion, the cleaning liquid is sprayed onto the corresponding cylinder sleeve through each spraying device to clean the cylinder sleeve; setting the ratio of the cleaning liquid initially added into each spraying device as A 0=A*(0.6+0.25*i0w0);
Wherein A is the proportion of the cleaning solution initially added into the spraying device, and is calculated according to the recommended concentration in the use instruction of the cleaning solution; the central control system adjusts the dosage of the cleaning liquid by adjusting the opening of a solenoid valve arranged on the infusion tube, thereby changing the proportion of the cleaning liquid;
S3, when the cleaning time is T h, suspending cleaning, acquiring a surface image of the cylinder sleeve through an image acquisition device, judging the pollution degree i h at the moment, determining the type of the surface pollutant according to an energy spectrum analyzer and an image amplifying device, calculating the proportion w h of the greasy dirt pollutant in the surface pollutant,
H is the detection times, and h is N +;
If i h =0, closing the spraying device corresponding to the cylinder sleeve;
if i h is not equal to 0, the central control system corrects the dosage of the cleaning solution to A h according to i h and w h;
S4, repeating the step S3 until all the spraying devices corresponding to all the cylinder jackets are stopped.
As a further explanation of this embodiment, in step S3, the specific way to correct the amount of the cleaning liquid added to a h according to i h and w h is as follows:
Ah=Ah-1*[1-0.2*(1-ih/ih-1)-0.1*(1-wh/wh-1)+mh],mh To correct the deviation value.
In the above calculation method, 1-i h/ih-1 is taken to represent the reduction ratio of the contamination level, since the contamination level of the cylinder liner surface is gradually reduced as the cleaning process proceeds, i h/ih-1 is less than 1, that is, 0.2 x (1-i h/ih-1) is a positive value, and the function in the above formula is to reduce the amount of the cleaning liquid to reduce the concentration of the cleaning liquid;
However, the oil contamination ratio is not necessarily gradually reduced, and it is possible that the cleaning speed of other particulate pollutants is greater than that of the oil contamination, which results in w h>wh-1, where w h/wh-1 is greater than 1, then 1-w h/wh-1 is negative, that is, 0.1 x (1-w h/wh-1) is negative, and the effect is to increase the concentration of the cleaning solution, specifically, to compensate for the reduced amount of cleaning solution due to the contamination level i h;
of course, if w h≤wh-1 demonstrates that the rate at which the greasy contaminants are washed is greater than or equal to the rate at which the remaining particulate contaminants are washed, where w h/wh-1 is less than 1, then 1-w h/wh-1 is positive, that is, 0.1 x (1-w h/wh-1) is positive, and the amount of cleaning fluid used can be further reduced.
According to the scheme, the pollution degree and the oil stain content ratio are monitored at a plurality of time points, and the system can dynamically adjust the consumption of the cleaning liquid according to the current pollution condition. The cleaning device has the advantages that the cleaning device is beneficial to ensuring that enough cleaning liquid is used when the pollution is serious, the consumption is reduced when the pollution is lightened, and the cleaning device can timely adjust the consumption of the cleaning liquid according to the actual condition of the cylinder sleeve and the change in the cleaning process, so that the cleaning effect is ensured. On the other hand, the consumption of the cleaning liquid is accurately controlled, so that the waste can be avoided, and the consumption of the cleaning liquid is reduced.
As a further explanation of the present embodiment, in step S3, the manner of determining the corrected deviation value m h is as follows: when T h is measured by a temperature sensor, the cylinder liner surface temperature D h is compared with the cleaning liquid optimum use temperature D Label (C) :
When |d h-D Label (C) ∣/Dh +% m h =0;
the temperature difference of 5% hardly affects the activity of the cleaning liquid, so the correction deviation value is 0;
When (D h-D Label (C) )/Dh >5%, m h=0.3*(Dh-D Label (C) )/Dh;
When the temperature is 5% higher than the optimal use temperature, the cleaning liquid activity decreases. Generally, the temperature increases and the chemical reaction rate increases, which means that the decontamination reaction during cleaning proceeds faster, but this is not found to be the case during use, because the active ingredients in the cleaning solution may be sensitive to temperature and high temperatures may cause decomposition or failure of these ingredients, thereby reducing the cleaning effect; on the other hand, the high temperature also reduces the adhesion of the cleaning liquid to the cylinder liner surface, thereby affecting the cleaning effect of the cleaning liquid, so that m h is a positive value at this time, and compensates for the reduced cleaning liquid concentration.
When (D h-D Label (C) )/Dh < -5%, m h=0.3*(D Label (C) -Dh)/Dh;
When the temperature is lower than the optimal use temperature by 5%, the activity of the cleaning solution is reduced, and the reaction rate of the lower temperature is slowed down, so that the cleaning effect of the cleaning solution is affected. So that m h is still a positive value at this time, again compensating for the reduced cleaning solution concentration.
The scheme considers the influence of temperature on the cleaning effect, and adapts to different temperature conditions by adjusting the consumption of the cleaning liquid. This adaptation enables the cleaning system to maintain a stable cleaning effect under different circumstances.
Wherein, the optimal use temperature D Label (C) of the cleaning solution can be obtained according to the use instruction of the cleaning solution.
As a further explanation of the present embodiment, it further includes:
And S5, spraying clear water without cleaning liquid by all spraying devices to wash the surface of the cylinder sleeve. The purpose of this step is to foam the cleaning fluid remaining on the cleaned cylinder liner to prevent the residue from affecting subsequent processing or use.
Of course, the present invention is capable of other various embodiments and its several details are capable of modification and variation in light of the present invention, as will be apparent to those skilled in the art, without departing from the spirit and scope of the invention as defined in the appended claims.
