[0087] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0088] The embodiment of the present application provides a spray high-pressure washing sand drying method based on three-stage power blast. The execution subject of the spray high-pressure washing sand drying method based on three-stage power blast includes but is not limited to at least one of the electronic devices such as a server and a terminal that can be configured to execute the method provided by the embodiment of the present application.

The server includes but is not limited to: a single server, a server cluster, a cloud server or a cloud server cluster, etc.

[0089] Reference Figure 1FIG. 1 is a flow chart of a spray high-pressure washing sand drying method based on three-stage power blasting provided by an embodiment of the present invention. In this embodiment, the spray high-pressure washing sand drying method based on three-stage power blasting includes:

[0090] S1. Performing a first air duct evaporation test on the pre-acquired wet sand to be dried according to a preset first-level blast power gradient to obtain a first evaporation mass set and a first evaporated wet sand set.

[0091] In detail, the wet sand to be dried is wet sand that has been sprayed with high-pressure water, the first-level blowing power gradient refers to the blowing power gradient for blowing and evaporating the wet sand to be dried in the first air duct using the first blower, and the first evaporation mass set refers to the evaporated water mass set corresponding to the first-level blowing power in the first-level blowing power gradient.

[0092] It can be explained that the first-level blast power gradient can be: 1000w, 1200w, 1400w, 1600w, etc. The first air duct evaporation test refers to using the first air duct to perform evaporation tests on the wet sand to be dried with different blast powers according to the first-level blast power gradient. See the following embodiments for details. The first evaporated wet sand set refers to the residual mass set of the wet sand to be dried obtained after the wet sand to be dried is subjected to an evaporation test in the first air duct using the first-level blast power gradient. For example: when the mass of the wet sand to be dried is 100kg, the first evaporation mass set can be: 1kg, 2kg, 3kg, 4kg, and the corresponding first evaporated wet sand set is 99kg, 98kg, 97kg, 96kg.

[0093] It is understandable that since wet sand that has not been sprayed with high pressure contains more impurities, spraying with high pressure is required.

[0094] In detail, during the first air duct evaporation test, the wet sand to be dried is first conveyed to the feed port above the first air duct by a conveyor belt, and then the wet sand to be dried falls freely under the action of gravity. During this process, the blower in the first air duct is started to perform blowing evaporation from bottom to top, and finally the wet sand to be dried falls into the carrying platform in the first air duct for carrying the first evaporated wet sand, thereby completing the first air duct evaporation test.

[0095] In the embodiment of the present invention, the first air duct evaporation test is performed on the pre-acquired wet sand to be dried according to the preset first-level blast power gradient to obtain the first evaporation mass set and the first evaporated wet sand set, including:

[0096] identifying the initial wet sand mass of the wet sand to be dried;

[0097] extracting the primary blast power in the primary blast power gradient in sequence, and performing blast evaporation on the wet sand to be dried in the first air duct according to the primary blast power to obtain a first evaporated wet sand set;

[0098] The first evaporated wet sand is sequentially extracted from the first evaporated wet sand set, the first wet sand mass of the first evaporated wet sand is identified, and the first evaporated mass is calculated according to the initial wet sand mass and the first wet sand mass using the following formula to obtain the first evaporated mass set:

[0099] m ′ 1 =M 0 -M 1

[0100] Among them, m ′ 1 Indicates the first evaporation mass, M 0 represents the initial wet sand mass, M 1 Indicates the first wet sand mass.

[0101] It should be understood that the initial wet sand mass refers to the mass of the wet sand to be dried. The first wet sand mass refers to the mass of the first evaporated wet sand.

[0102] S2. Plot points in a pre-constructed power-evaporation mass coordinate system according to the primary blast power gradient and the first evaporation mass set to obtain a primary evaporation fitting point set.

[0103] In detail, the horizontal axis of the power-evaporation mass coordinate system represents the blowing power, and the vertical axis represents the evaporation mass.

[0104] Furthermore, the first-level evaporation fitting point set refers to a set of fitting points determined according to the correspondence between the first-level blowing power and the first evaporation mass during the first air duct evaporation test. For example, when the first-level blowing power is 1000w, the first evaporation mass is 1kg. At this time, the determined first-level evaporation fitting point is (1000w, 1kg).

[0105] It can be understood that the first-level evaporation fitting point set is obtained by plotting points in a pre-constructed power-evaporation mass coordinate system according to the first-level blast power gradient and the first evaporation mass set, including:

[0106] Identifying in the first evaporation mass set a first evaporation mass corresponding to each first-level blast power in the first-level blast power gradient;

[0107] The coordinates of the first-level power evaporation point are determined in the power-evaporation mass coordinate system according to the first-level blowing power and the first evaporation mass, so as to obtain a first-level evaporation fitting point set.

[0108] Furthermore, the first-level power evaporation point coordinates refer to the coordinates of the first-level evaporation fitting point in the power-evaporation mass coordinate system, for example: (1000w, 1kg).

[0109] S3. Perform a second air duct evaporation test on each first evaporated wet sand in the first evaporated wet sand set according to a preset secondary blowing power gradient to obtain multiple groups of second evaporation mass sets and multiple groups of second evaporated wet sand sets.

[0110] In detail, the secondary blowing power gradient refers to the blowing power gradient of the first evaporated wet sand being blown and evaporated by the second blower in the second air duct, and the second evaporation mass set refers to the set of evaporated water masses of the first evaporated wet sand at each secondary blowing power in the secondary blowing power gradient.

[0111] For example, the secondary blowing power gradient may be 800w, 900w, 1000w, 1100w, and so on.

[0112] Further, the second air duct evaporation test refers to using the second air duct to perform evaporation tests of the first evaporated wet sand at different blowing powers according to the secondary blowing power gradient, as described in the following embodiments. Since the first evaporated wet sand set includes a plurality of first evaporated wet sands, each first evaporated wet sand corresponds to a set of second evaporation mass sets, and therefore, the first evaporated wet sand set corresponds to a plurality of second evaporation mass sets. Similarly, each first evaporated wet sand corresponds to a set of second evaporated wet sand sets, and therefore, the first evaporated wet sand set corresponds to a plurality of second evaporation wet sand sets.

[0113] In the embodiment of the present invention, the second duct evaporation test is performed on each first evaporated wet sand in the first evaporated wet sand set according to the preset secondary blast power gradient to obtain multiple groups of second evaporation mass sets and multiple groups of second evaporated wet sand sets, including:

[0114] extracting secondary blowing power in the secondary blowing power gradient in sequence, and using the secondary blowing power to blow and evaporate the first evaporated wet sand in the second air duct to obtain second evaporated wet sand;

[0115] The second wet sand mass of the second evaporated wet sand is identified, and the second evaporated mass is calculated according to the first wet sand mass and the second wet sand mass using the following formula:

[0116] m ′ 2 =M 1 -M 2

[0117] Among them, m ′ 2 Indicates the second evaporation mass, M 2 Indicates the second wet sand mass;

[0118] The second evaporation mass sets of each first evaporated wet sand under the secondary blast power gradient are collected to obtain multiple groups of second evaporation mass sets, and the second evaporation wet sand sets of each first evaporated wet sand under the secondary blast power gradient are collected to obtain multiple groups of second evaporated wet sand sets.

[0119] For example, when the first evaporated wet sand set is 100kg, 101kg, 102kg, and 103kg, and the secondary blowing power is 800w, the second evaporated wet sand set can be 99.5kg, 100.4kg, 101.3kg, and 102.1kg, and the corresponding second evaporation mass set is 0.5kg, 0.6kg, 0.7kg, and 0.9kg; when the secondary blowing power is 900w, the second evaporated wet sand set can be 98.5kg, 99.4kg, 100.3kg, and 101.1kg, and the corresponding second evaporation mass set is 1.5kg, 1.6kg, 1.7kg, and 1.9kg; when the secondary blowing power is 1000w, the second evaporated wet sand set can be 97.5kg, 98.4kg, 99.3kg, and 100.1kg, and the corresponding second evaporation mass set is 2.5kg, 2.6kg, 2.7kg, and 2.9kg.

[0120] S4. According to the secondary blast power gradient and multiple sets of second evaporation mass sets, the primary evaporation fitting point set is used to perform point mapping, thereby obtaining multiple sets of secondary evaporation fitting point sets.

[0121] It should be understood that the multiple sets of secondary evaporation fitting point sets refer to a set of fitting points determined on the basis of the primary evaporation fitting point set according to the correspondence between the secondary blowing power and the second evaporation mass during the second air duct evaporation test.

[0122] In the embodiment of the present invention, the plotting is performed using the primary evaporation fitting point set according to the secondary blast power gradient and the multiple sets of second evaporation mass sets, and multiple sets of secondary evaporation fitting point sets may be provided, including:

[0123] Extracting the first-level evaporation fitting points in sequence from the first-level evaporation fitting point set, and identifying the first-level blast power and the first evaporation mass of the first-level evaporation fitting points;

[0124] sequentially extracting the secondary blast power from the secondary blast power gradient, and sequentially extracting the second evaporation mass sets from the plurality of second evaporation mass sets;

[0125] According to the primary blast power, the secondary blast power, the first evaporation mass and the second evaporation mass in the second evaporation mass concentration, the secondary power evaporation point coordinates of the secondary evaporation fitting point are calculated using the following formula:

[0126]

[0127] Among them, P2 The horizontal coordinate value of the secondary power evaporation point coordinate, P 1 Indicates the first-stage blast power, p 2 Indicates the secondary blast power, M 2 The ordinate value representing the coordinates of the secondary power evaporation point;

[0128] Points are drawn in the power-evaporation mass coordinate system according to the coordinates of the secondary power evaporation points to obtain a secondary evaporation fitting point set, and the secondary evaporation fitting point set of each primary evaporation fitting point is summarized to obtain multiple groups of secondary evaporation fitting point sets.

[0129] For example, when the first-level power evaporation point coordinates of the first-level evaporation fitting point are (1000w, 1kg), the second-level blowing power is 800w, and the second evaporation mass is 0.5kg, the corresponding second-level power evaporation point coordinates are (1800w, 1.5kg); the second-level blowing power is 900w, the second evaporation mass is 0.6kg, and the corresponding second-level power evaporation point coordinates are (1900w, 1.6kg); the second-level blowing power is 1000w, the second evaporation mass is 0.7kg, and the corresponding second-level power evaporation point coordinates are (2000w, 1.7kg). At this time, the second-level power evaporation point coordinates of the second-level evaporation fitting points in the second-level evaporation fitting point set are (1800w, 1.5kg), (1900w, 1.6kg), and (2000w, 1.7kg), respectively.

[0130] S5. Perform a third air duct evaporation test on each of the multiple groups of second evaporated wet sand sets using the pre-constructed third air duct to obtain multiple groups of three-level blowing power gradients.

[0131] It can be understood that the three-level blowing power gradient refers to using the third blower to collect each group of second evaporated wet sand in the third air duct to complete the drying blowing power sequence.

[0132] In detail, the third air duct evaporation test refers to using the third air duct to perform a third stage evaporation test on the second evaporated wet sand based on the dryness of the second evaporated wet sand reaching a preset dryness threshold value, as detailed in the following embodiments.

[0133] It can be understood that the third air duct evaporation test is performed on each of the plurality of second evaporation wet sand sets by using the pre-constructed third air duct to obtain a plurality of sets of three-level blast power gradients, including:

[0134] Sequentially extracting second evaporated wet sand from the plurality of groups of second evaporated wet sand collections, and performing a blast evaporation test on the second evaporated wet sand in the third air duct until target evaporated dry sand is obtained, wherein the target evaporated dry sand refers to dry sand whose dryness reaches a preset dryness threshold after the blast evaporation test in the third air duct, and the mass difference between the target evaporated dry sand and the second evaporated wet sand is the third evaporation mass of the second evaporated wet sand;

[0135] The test blast power of the target evaporated dry sand during the blast evaporation test is identified, and the test blast powers of each second evaporated wet sand are collected to obtain multiple groups of three-level blast power gradients.

[0136] It can be understood that the dryness refers to the ratio of the mass of pure dry sand in the target evaporated dry sand to the mass of the target evaporated dry sand, and the mass of pure dry sand refers to the mass of the target evaporated dry sand minus the mass of water in the target evaporated dry sand. The dryness threshold can be 99.9 / 100 (i.e., 99.9%). After obtaining the target evaporated dry sand, the target evaporated dry sand is stored in the third silo.

[0137] For example, when the mass of the second wet sand of the second evaporation wet sand is 102 kg, in the third air duct evaporation test, when the blowing power is 700 w, 800 w, 900 w and 1000 w, the mass of the sand obtained is 101.5 kg, 101 kg, 100 kg and 97.5 kg respectively, and the 101.5 kg sand contains 0.5 kg of water and the dryness is about 99.5%, and the 101 kg sand contains 0.4 kg of water and the dryness is about 9 9.6%, 100kg of sand contains 0.1kg of moisture and the dryness is 99.90%, 97.5kg of sand contains 0.05kg of moisture and the dryness is about 99.95%. At this time, the blowing power of 700w and 800w does not meet the standard of the target evaporated dry sand, the blowing power of 900w just meets the standard of the target evaporated dry sand, and the blowing power of 1000w exceeds the standard of the target evaporated dry sand. Therefore, the test blowing power for the second evaporated wet sand should be 900w.

[0138] S6.

The optimal blast power sequence refers to the optimal blast power sequence determined according to the target blast power sequence and meeting the user's standard.

[0140] In the embodiment of the present invention, the target blast power sequence is identified according to the primary evaporation fitting point set, multiple groups of secondary evaporation fitting point sets and multiple groups of third-level blast power gradients, including:

[0141] Extracting first-level evaporation fitting points in sequence from the first-level evaporation fitting point set, and extracting a group of second-level evaporation fitting point sets corresponding to the first-level evaporation fitting points from the multiple groups of second-level evaporation fitting point sets;

[0142] Connecting the primary evaporation fitting point with the corresponding set of secondary evaporation fitting points in sequence to obtain a power evaporation path set of the primary evaporation fitting point;

[0143] Extracting power evaporation paths in sequence from the power evaporation path set, and identifying the three-level blast power corresponding to the power evaporation path in the multiple groups of three-level blast power gradients;

[0144] Extracting the coordinates of the secondary power evaporation points corresponding to the secondary evaporation fitting points in the power evaporation path;

[0145] identifying a third evaporation mass corresponding to the secondary evaporation fitting point;

[0146] According to the coordinates of the secondary power evaporation point, the third-level blast power and the third evaporation mass, the coordinates of the third-level power evaporation point of the power evaporation path are calculated using the following formula:

[0147]

[0148] Among them, P 3 The horizontal coordinate value of the third-level power evaporation point coordinate, p 3 Indicates the third-level blast power, M 3 Indicates the vertical coordinate value of the third-level power evaporation point coordinate, m ′ 3 Indicates the third evaporation mass;

[0149] According to the coordinates of the three-level power evaporation points, points are drawn in the power-evaporation mass coordinate system to obtain three-level evaporation fitting points;

[0150] Connecting the secondary evaporation fitting point in the power evaporation path with the tertiary evaporation fitting point to obtain a target power evaporation path set;

[0151] Identify the unit evaporation power consumption of each target power evaporation path in the target power evaporation path set to obtain a unit evaporation power consumption set, wherein the unit evaporation power consumption refers to the electric energy consumed for drying a unit mass of wet sand to be dried through the target power evaporation path;

[0152] Identifying a minimum unit evaporation power consumption in the unit evaporation power consumption set, and identifying a minimum power consumption evaporation path corresponding to the minimum unit evaporation power consumption;

[0153] The primary blast power, the secondary blast power and the tertiary blast power in the minimum power consumption evaporation path are identified, and the target blast power sequence is established according to the primary blast power, the secondary blast power and the tertiary blast power in the minimum power consumption evaporation path.

[0154] It can be understood that the power evaporation path set refers to the set of routes obtained by sequentially connecting the first-level evaporation fitting point with each second-level evaporation fitting point in a corresponding set of second-level evaporation fitting points. The third evaporation mass refers to the mass difference between the second evaporation wet sand and the target evaporation dry sand corresponding to the second-level evaporation fitting point. The third-level power evaporation point coordinates refer to the coordinates of the third-level evaporation fitting point in the power-evaporation mass coordinate system. The third-level evaporation fitting point refers to the set of fitting points determined on the basis of the multiple sets of second-level evaporation fitting point sets according to the correspondence between the third-level blast power and the third evaporation mass during the third duct evaporation test. The target power evaporation path set refers to the set of routes obtained by sequentially connecting a corresponding set of first-level evaporation fitting points, second-level evaporation fitting points and third-level evaporation fitting points. The minimum power consumption evaporation path refers to the target power evaporation path corresponding to the minimum unit evaporation power consumption.

[0155] In the embodiment of the present invention, the step of identifying the optimal blowing power sequence according to the target blowing power sequence includes:

[0156] Identify a first adjacent power evaporation path and a second adjacent power evaporation path of the minimum power consumption evaporation path in the target power evaporation path set, wherein the first adjacent power evaporation path is formed by sequentially connecting a first primary evaporation fitting point, a first secondary evaporation fitting point, and a first tertiary evaporation fitting point, and the second adjacent power evaporation path is formed by sequentially connecting a second primary evaporation fitting point, a second secondary evaporation fitting point, and a second tertiary evaporation fitting point;

[0157] Respectively identifying a first unit evaporation power consumption and a second unit evaporation power consumption of the first adjacent power evaporation path and a second adjacent power evaporation path;

[0158] determining whether the first unit evaporation power consumption is greater than the second unit evaporation power consumption;

[0159] If the first unit evaporation power consumption is greater than the second unit evaporation power consumption, determining an optimal power consumption path interval according to the second adjacent power evaporation path and the minimum power consumption evaporation path;

[0160] If the first unit evaporation power consumption is not greater than the second unit evaporation power consumption, determining an optimal power consumption path interval according to the first adjacent power evaporation path and the minimum power consumption evaporation path;

[0161] An acceptable unit power consumption difference value input by a user is received, and an optimal fan power sequence is selected in the optimal power consumption path interval according to the acceptable unit power consumption difference value.

[0162] It can be understood that the first adjacent power evaporation path and the second adjacent power evaporation path refer to two target power evaporation paths adjacent to the minimum power consumption evaporation path above and below, the first first-level evaporation fitting point, the first second-level evaporation fitting point and the first third-level evaporation fitting point respectively refer to the first-level evaporation fitting point, the second-level evaporation fitting point and the third-level evaporation fitting point in the first adjacent power evaporation path, and the second first-level evaporation fitting point, the second second-level evaporation fitting point and the second third-level evaporation fitting point respectively refer to the first-level evaporation fitting point, the second second-level evaporation fitting point and the third-level evaporation fitting point in the second adjacent power evaporation path.

[0163] Further, the first unit evaporation power consumption and the second unit evaporation power consumption refer to the unit evaporation power consumption corresponding to the first adjacent power evaporation path and the second adjacent power evaporation path, respectively. The optimal power consumption path interval refers to the path interval where the optimal blast power sequence is located. The acceptable unit power consumption difference refers to the unit evaporation power consumption difference used to adjust the accuracy of the optimal blast power sequence, as described in the following embodiments.

[0164] In the embodiment of the present invention, the selecting the optimal blowing power sequence in the optimal power consumption path interval according to the acceptable unit power consumption difference includes:

[0165] Identify a first boundary power consumption path and a second boundary power consumption path of the optimal power consumption path interval, wherein when the first unit evaporation power consumption is greater than the second unit evaporation power consumption, the first boundary power consumption path is a minimum power consumption evaporation path, and the second boundary power consumption path is a second adjacent power evaporation path; when the first unit evaporation power consumption is not greater than the second unit evaporation power consumption, the first boundary power consumption path is a first adjacent power evaporation path, and the second boundary power consumption path is a minimum power consumption evaporation path;

[0166] Identify an intermediate power consumption path in the optimal power consumption path interval, wherein the intermediate power consumption path is formed by sequentially connecting an intermediate first-level evaporation fitting point, an intermediate second-level evaporation fitting point, and an intermediate third-level evaporation fitting point, and the horizontal coordinate value of the intermediate first-level evaporation fitting point is equal to the average of the first-level blast power in the first boundary power consumption path and the first-level blast power in the second boundary power consumption path, the horizontal coordinate value of the intermediate second-level evaporation fitting point is equal to the average of the second-level blast power in the first boundary power consumption path and the second-level blast power in the second boundary power consumption path, and the horizontal coordinate value of the intermediate third-level evaporation fitting point is equal to the average of the third-level blast power in the first boundary power consumption path and the third-level blast power in the second boundary power consumption path;

[0167] Acquire the intermediate unit evaporation power consumption of the intermediate power consumption path, and calculate the unit power consumption difference between the intermediate unit evaporation power consumption and the minimum unit evaporation power consumption;

[0168] Determining whether the unit power consumption difference is less than the acceptable unit power consumption difference;

[0169] If the unit power consumption difference is not less than the acceptable unit power consumption difference, the first adjacent power evaporation path, the second adjacent power evaporation path and the minimum power consumption evaporation path are respectively updated by using the first boundary power consumption path, the second boundary power consumption path and the intermediate power consumption path, and the step of respectively identifying the first unit evaporation power consumption and the second unit evaporation power consumption of the first adjacent power evaporation path and the second adjacent power evaporation path is returned to;

[0170] If the unit power consumption difference is less than the acceptable unit power consumption difference, identifying the first-level blowing power, the second-level blowing power and the third-level blowing power of the intermediate power consumption path;

[0171] The optimal blowing power sequence is established according to the primary blowing power, the secondary blowing power and the tertiary blowing power of the intermediate power consumption path.

[0172] It is understandable that the first boundary power consumption path and the second boundary power consumption path refer to the first power evaporation path and the second power evaporation path on the boundary of the optimal power consumption path interval, respectively. For example, when the first unit evaporation power consumption is 0.1 kWh, the second unit evaporation power consumption is 0.2 kWh, and the minimum unit evaporation power consumption is 0.15 kWh, the first boundary power consumption path is the first adjacent power evaporation path, and the second boundary power consumption path is the minimum power consumption evaporation path.

[0173] Further, the intermediate power consumption path refers to an intermediate path belonging to the optimal power consumption path interval determined by the first-level blowing power in the first boundary power consumption path and the first-level blowing power in the second boundary power consumption path, the second-level blowing power in the first boundary power consumption path and the second-level blowing power in the second boundary power consumption path, the third-level blowing power in the first boundary power consumption path and the third-level blowing power in the second boundary power consumption path. After determining the average values ​​of the above three blowing powers, testing is performed based on the average values ​​of the three blowing powers to obtain the corresponding three evaporation masses, and the vertical coordinate values ​​are determined based on the three evaporation masses, thereby determining the intermediate first-level evaporation fitting point, the intermediate second-level evaporation fitting point and the intermediate third-level evaporation fitting point.

[0174] In detail, the intermediate unit evaporation power consumption refers to the unit evaporation power consumption corresponding to the intermediate power consumption path. The unit power consumption difference refers to the difference between the intermediate unit evaporation power consumption and the minimum unit evaporation power consumption. When the unit power consumption difference is not less than the acceptable unit power consumption difference, it means that the intermediate power consumption path does not meet the user's accuracy standard, and therefore it is necessary to recalculate the intermediate unit evaporation power consumption in a cycle. If the unit power consumption difference is less than the acceptable unit power consumption difference, the optimal blast power sequence is directly formed according to the first-level blast power, the second-level blast power and the third-level blast power of the intermediate power consumption path, and the optimal blast power sequence is used for spray high-pressure washing and sand drying.

[0175] In order to solve the problem described in the background technology, the present invention constructs a target blast power sequence through a first-level evaporation fitting point set, multiple groups of second-level evaporation fitting point sets and multiple groups of third-level blast power gradients, then identifies the optimal blast power sequence in the target blast power sequence, and finally uses the optimal blast power sequence to spray high-pressure washing sand drying. Therefore, it is necessary to first obtain a first-level evaporation fitting point set, multiple groups of second-level evaporation fitting point sets and multiple groups of third-level blast power gradients. When obtaining the first-level evaporation fitting point set, firstly perform a first duct evaporation test on the pre-acquired wet sand to be dried according to the preset first-level blast power gradient to obtain a first evaporation mass set and a first evaporated wet sand set. Then, according to the first-level blast power gradient and the first evaporation mass set, points are drawn in a pre-constructed power-evaporation mass coordinate system to obtain a first-level evaporation fitting point set. When obtaining multiple groups of second-level evaporation fitting point sets, it is necessary to perform a first evaporation test on the first evaporated wet sand set according to the preset second-level blast power gradient. Each first evaporated wet sand in the second duct is subjected to a second duct evaporation test to obtain multiple groups of second evaporation mass sets and multiple groups of second evaporated wet sand sets, and then according to the secondary blast power gradient and the multiple groups of second evaporation mass sets, the first evaporation fitting point set is used to draw points, and multiple groups of second evaporation fitting point sets are obtained. When obtaining multiple groups of three-level blast power gradients, it is necessary to use the pre-constructed third duct to perform a third duct evaporation test on each second evaporated wet sand in the multiple groups of second evaporation wet sand sets to obtain multiple groups of three-level blast power gradients. Further, the three-level blast power gradient refers to the blast power sequence for drying each group of second evaporated wet sand sets in the third duct. Finally, the target blast power sequence can be identified according to the first evaporation fitting point set, the multiple groups of second evaporation fitting point sets and the multiple groups of three-level blast power gradients, and then the optimal blast power sequence can be identified according to the target blast power sequence, and the optimal blast power sequence is used to spray high-pressure washed sand drying. Therefore, the present invention can solve the problems of low drying efficiency and high energy consumption in the current process of drying washed sand.

[0179] The secondary evaporation fitting point plotting module 102 is used to perform a second air duct evaporation test on each first evaporated wet sand in the first evaporated wet sand set according to a preset secondary blast power gradient, to obtain multiple sets of second evaporation mass sets and multiple sets of second evaporation wet sand sets, wherein the secondary blast power gradient refers to the blast power gradient for blast evaporation of the first evaporated wet sand in the second air duct, and the second evaporation mass set refers to the set of evaporated water masses of the first evaporated wet sand at each secondary blast power in the secondary blast power gradient; according to the secondary blast power gradient and the multiple sets of second evaporation mass sets, the primary evaporation fitting point set is used for plotting, to obtain multiple sets of secondary evaporation fitting point sets;
