[0048] A cleaning method for a self-cleaning device of a mixer, including a self-cleaning system of the mixer. The self-cleaning system of the mixer includes a cleaning module and an adjustment module. The cleaning module includes a telescopic control sub-module, a liquid transmission sub-module, and a valve control sub-module. The telescopic control sub-module is electrically connected to the linear drive. The liquid transmission sub-module is electrically connected to the first pump body 25 and the second pump body 21.

[0049] The telescopic control sub-module includes a distance recognition unit for recognizing the length of the support rod 12 extended. The valve control sub-module includes a metering unit for recording the amount of liquid sprayed out.

[0050] The adjustment module includes a logic judgment sub-module, a speed control sub-module, a liquid level height receiving sub-module, and a comparison sub-module. The speed control sub-module is electrically connected to the speed reducer 3. The liquid level height receiving sub-module is electrically connected to the liquid level sensor 26.

[0051] The self-cleaning system of the mixer includes the following specific operation steps:

[0052] Step 1: When the mixer needs to be cleaned, first discharge the materials in the housing 1, start the cleaning component, and pour the external liquid into the cleaning rod 8 to clean the inside of the housing 1.

[0053] Specifically, start the first pump body 25 and the second pump body 21 at the same time, transport the cleaning agent and the liquid to the fourth liquid infusion tank 22, so that the two form a mixed liquid. Open the spray head 15 to spray the mixed liquid onto the inner wall surface of the housing 1. Start the speed reducer 3 to drive the rotating rod 6 to rotate, thereby driving the spray head 15 to rotate so that the inner wall of the housing 1 can be sprayed with the mixed liquid, which is convenient for the impurities on the inner wall of the housing 1 to soften and fall off. When the mixed liquid is sprayed and contacted, start the linear drive through the telescopic control sub-module, so that the scraping plate 14 on the cleaning rod 8 contacts the inner wall of the housing 1, and the rotating rod 6 still rotates, so that the scraping plate 14 can scrape off the fallen impurities.

[0054] After using the mixed liquid, in order to ensure the cleanliness of the inner wall of the housing 1, close the second pump body 21, start the first pump body 25, pump the liquid in the water source to the cleaning rod 8, and then spray it onto the inner wall of the housing 1 through the spray head 15 to brush off the impurities on the inner wall of the housing 1 and ensure the cleanliness of the inner wall of the housing 1.

[0055] Through the above steps, the inner wall of the housing 1 can be sprayed with a cleaning agent and a liquid successively, effectively scraping off impurities.

[0056] Step 2: After the first cleaning is completed, close the second valve 18. The liquid and the cleaning agent will flow into the bottom of the housing 1 to form a mixed liquid. The liquid level sensor 26 detects the height of the mixed liquid inside the housing 1 to judge the amount of impurities scraped off from the inner wall of the housing 1.

[0057] It should be noted that this step is judged under the condition that the transportation of the liquid and the cleaning agent is closed after the impurities on the inner wall of the housing 1 are cleaned.

[0058] Step 3: After the first cleaning is completed, the distance recognition unit is used to recognize the extended length of the support rod 12 and compare it with the radius of the housing 1 to judge the degree of impurity attachment on the inner wall of the housing 1, so as to adjust the state of the cleaning component to improve the cleaning quality.

[0059] Step 2 includes the following operating steps:

[0060] Step 2-a: When the cleaning agent and the liquid are transported into the housing 1, the metering unit monitors the amount of the cleaning agent and the liquid entering the housing 1 to form a mixed liquid.

[0061] Specifically, the metering unit respectively records the amount of the cleaning agent entering the housing 1 as , the amount of the liquid entering the housing 1 as , and the total amount calculation formula of the mixed liquid is: , where is the total amount of the mixed liquid.

[0062] It should be noted that the unit of the liquid amount is volume;

[0063] Step 2-b: The liquid level sensor 26 monitors the height of the bottom of the housing 1, analyzes the actual volume of the mixed liquid, and then calculates the amount of impurities scraped off from the inner wall of the housing 1 through the comparison sub-module in combination with the total amount of the mixed liquid.

[0064] Specifically, the calculation formula of the actual volume of the mixed liquid is: , where, is the actual volume of the mixed liquid, is the actual height of the mixed liquid, and S is the area of the bottom of the housing 1;

[0065] The calculation formula of the amount of impurities scraped off from the inner wall of the housing 1 is: , where is the proportion of the impurities scraped off from the inner wall of the housing 1 to the actual volume of the mixed liquid. When , it means that the amount of scraped impurities is small, which is low level. When , it means that the amount of scraped impurities is large, which is high level.

[0066] Step three includes the following steps:

[0067] Step three-a: Set the radius of the housing 1 as L in the logic judgment sub-module, and the distance between the side of the scraping plate 14 close to the inner wall of the housing 1 and the rotating rod 6 monitored in real time by the distance recognition unit is , and compare the two to determine whether the impurities on the inner wall of the housing 1 are cleaned up;

[0068] Specifically, when L is equal to , it indicates that the impurities on the inner wall of the housing 1 are cleaned up. When is less than L, it indicates that the impurities on the inner wall of the housing 1 are not cleaned up, and judge the degree of impurity adhesion on the inner wall of the housing 1;

[0069] Further judge the degree of impurity adhesion. The calculation formula is: , where is the ratio of the thickness of the impurities attached to the inner wall of the housing 1 to the radius of the housing 1. When , it means that the thickness of the impurities attached to the inner wall of the housing 1 is low level. When , it means that the thickness of the impurities attached to the inner wall of the housing 1 is high level.

[0070] Step three-b: Combine the degree of cleaning of the impurities on the inner wall of the housing 1 with the amount of scraped impurities to analyze the firmness of the impurity adhesion on the inner wall of the housing 1;

[0071] Specifically, when the impurities attached to the inner wall of the housing 1 are of low level and the amount of scraped impurities is of high level, it indicates that the firmness of the impurity adhesion on the inner wall of the housing 1 is of low level, indicating that the impurities on the inner wall of the housing 1 are easy to be scraped off;

[0072] When the impurities attached to the inner wall of the housing 1 are of low level and the amount of scraped impurities is of low level, and when the impurities attached to the inner wall of the housing 1 are of high level and the amount of scraped impurities is of high level, it indicates that the firmness of the impurity adhesion on the inner wall of the housing 1 is of medium level, and only part of them can be scraped off;

[0073] When the impurities attached to the inner wall of the housing 1 are of high level and the amount of scraped impurities is of low level, it indicates that the firmness of the impurity adhesion on the inner wall of the housing 1 is of high level and it is difficult to be scraped off;

[0074] Step three-c: Adjust the state of the cleaning component according to the situation of the impurity adhesion on the inner wall of the housing 1, so as to improve the quality of cleaning impurities;

[0075] Specifically, when the degree of firm adhesion of impurities on the inner wall of the housing 1 is medium, repeat the cleaning steps of Step 1. Different from Step 1, first turn on the second pump body 21, spray the cleaning agent onto the inner wall of the housing 1 through the nozzle 15, and let it stand for a period of time to give more reaction time, so that the impurities that are difficult to scrape off can be automatically detached better. After a period of time, when continuing to control the scraper 14 to contact the inner wall of the housing 1, continue to control the support rod 12 to slowly extend through the telescopic control sub-module, strengthen the pressure of the scraper 14 contacting the inner wall of the housing 1, improve the efficiency of scraping off impurities, and when the support rod 12 extends, continue to recognize through the distance unit that L is equal to or indicates successful processing;

[0076] When the degree of firm adhesion of impurities on the inner wall of the housing 1 is high, repeat the above cleaning method. Different from the above method, after the cleaning agent stands for a period of time, transmit the signal to the telescopic control sub-module to control the support rod 12 to extend (Based on extend a distance of half the thickness of the impurities), perform layered processing to avoid impurities with a high degree of firmness at one time, and continue to control the nozzle 15 to work while the scraper 14 is running, spray the cleaning agent while scraping the impurities, and control the reduction gear 3 to reduce the rotation speed through the rotation control sub-module, thereby driving the rotation speed of the rotating rod 6 to decrease, so as to reduce the working speed of the scraper 14, and the impurities can be fully scraped off to avoid the phenomenon of "blade yielding" caused by too fast a speed;

[0077] After this layer is scraped, then control the support rod 12 to continue to extend, and continuously scrape the impurities on the inner wall of the housing 1 during the extension process until the scraper 14 contacts the inner wall of the housing 1, and the remaining impurities can be scraped off. After scraping off the impurities in this mode, if the impurities are still not scraped clean, it means that there is a "blade yielding" phenomenon, indicating that there is a problem during the cleaning of the cleaning component, and it is necessary to pause the work for the staff to repair or replace the cleaning component to ensure the working efficiency of the cleaning component;

[0078] It should be noted that since the scraper 14 works while spraying the cleaning agent and the speed of the scraper 14 is reduced, the reaction time between the cleaning agent and the impurities can be further increased, and the impurities can be scraped off better.

[0079] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0080] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
