Description

Technical Field

[0001] The invention belongs to the field of separation technology, and in particular relates to a serial control system and a control method for a setting machine and a fume purifier. Background Art

[0002] The setting machine is a key equipment for textile printing and dyeing finishing. During the heat setting process of the fabric, the temperature is high, so a large amount of high-temperature gas is generated in the setting machine oven. The high-temperature gas contains pollutants such as organic oil, dyes, dye additives, lubricating oil, fiber particles, etc. Therefore, how to purify the fume has become a technical problem that needs to be solved urgently.

[0003] In the existing technical solution, the invention patent application CN109999580A "An oil mist purifier for a chemical fiber setting machine with strong anti-emulsification performance" can scrape off the oil mist through the overall shaking of the exhaust gas decomposition mechanism, combined with the oil mist scraping mechanism, to prevent the oil mist from clogging the filter mesh and increase the passing rate of the oil mist. However, at the same time, there are the following technical problems:

[0004] In order to achieve the oil fume cleaning treatment of the stenter, the existing technical solutions often use the range hood to clean the oil fume of the stenter with a fixed air volume. Since the oil fume pressure of the stenter is not constant, if the air volume of the purifier cannot be controlled according to the oil fume pressure of the stenter, the purifier cannot be operated energy-savingly.

[0005] In view of the above technical problems, the present invention provides a series control system and control method for a setting machine and a fume purifier. Summary of the invention

[0006] To achieve the purpose of the present invention, the present invention adopts the following technical solutions:

[0007] According to one aspect of the present invention, a method for serially controlling a setting machine and a fume purifier is provided.

[0008] A method for serially controlling a setting machine and a fume purifier, specifically comprising:

[0009] S1 connects multiple setting machines with the oil fume purifier for processing, and determines the operation overlap with the preset oil fume pressure range according to the monitoring data of the oil fume pressure of different setting machines, and determines whether there is a setting machine with oil fume pressure in a state of concern among the setting machines based on the operation overlap, if yes, proceed to the next step, if not, proceed to step S4;

[0010] S2 takes the setting machine whose oil fume pressure is in the concerned state as the concerned setting machine, and determines that the purification treatment demand of the oil fume purifier is within the preset demand range based on the monitoring data of the oil fume pressure of different concerned setting machines and the operation overlap of the preset oil fume pressure range, and then proceeds to the next step;

[0011] S3 determines the change of the monitoring data of the oil fume pressure of different setting machines based on the monitoring data of the oil fume pressure of different setting machines, and when it is determined that the oil fume purifier does not need to operate at the maximum wind force according to the change, proceeds to the next step;

[0012] S4 determines the operating ranges of the oil fume pressures of different setting machines based on the analysis results of the monitoring data of the oil fume pressures of different setting machines, and outputs the wind force control results of the oil fume purifier based on the operating ranges of the oil fume pressures of different setting machines.

[0013] The beneficial effects of the present invention are:

[0014] By utilizing the changes in the monitoring data of the oil fume pressure of different setting machines, it is determined whether the oil fume purifier needs to operate at the maximum wind speed, thereby avoiding the technical problem that the purification results of the oil fume purifier do not meet the requirements due to the drastic fluctuations in the monitoring data of the oil fume pressure. In addition, by further combining the purification needs of the oil fume purifier within the preset demand range, the reliability of the oil fume purification treatment is achieved under certain purification needs and in the presence of large fluctuations.

[0015] The wind force control result of the oil fume purifier is output based on the operating range of the oil fume pressure of different setting machines, thereby avoiding the technical problem of poor energy saving effect caused by the use of fixed wind force. By combining the operating range of the oil fume pressure of different setting machines, dynamic adjustment of the wind force control result is achieved according to the actual purification demand of the oil fume pressure. On the basis of meeting the oil fume purification treatment needs, energy-saving control of the oil fume purifier is also achieved.

[0016] A further technical solution is to connect multiple setting machines with the oil fume purifier, specifically including:

[0017] After a plurality of setting machines are connected in parallel, they are uniformly connected to the oil fume purifier.

[0018] A further technical solution is that the preset oil fume pressure range is a pressure range whose deviation from the rated pressure of the setting machine is within a preset deviation range.

[0019] A further technical solution is that the operation overlap situation includes the number of operations falling within the preset oil fume pressure range and the duration of different operation times.

[0020] A further technical solution is that the method for determining the setting machine whose oil fume pressure is in a state of concern is:

[0021] Based on the operation overlap, determining the cumulative operation time of the setting machine in the preset oil fume pressure range;

[0022] Determining the operation overlap coefficient of the setting machine according to the ratio of the cumulative operation time to the cumulative operation time;

[0023] Whether the setting machine is a setting machine whose oil fume pressure is in a state of concern is determined by the operation overlap coefficient.

[0024] A further technical solution is that when the operation overlap coefficient of the setting machine is greater than a preset overlap coefficient threshold, the setting machine is determined to be a setting machine whose oil fume pressure is in a state of concern.

[0025] A further technical solution is that the method for outputting the wind force control result of the oil fume purifier is:

[0026] Determine the oil fume pressure of different setting machines at different operating moments based on the operating range of the oil fume pressure of different setting machines, and determine the oil fume pressure and of different operating time by the oil fume pressure at different operating moments;

[0027] According to the oil smoke pressure of different operating time, the accumulated operating time in different operating intervals is determined, and the operating interval range corresponding to the accumulated operating time ratio greater than the preset time ratio is determined through the accumulated operating time of different operating intervals, and it is used as the common operating interval range;

[0028] The wind force control result of the oil fume purifier is outputted through a commonly used operating range.

[0029] A further technical solution is to output the wind force control result of the oil fume purifier through a commonly used operating range, specifically including:

[0030] The wind force control result of the oil fume purifier is determined by the maximum value of the preset wind force control amount in different operating intervals corresponding to the commonly used operating interval range.

[0031] In a second aspect, the present application provides a sizing machine and a fume purifier interlocking control system, which is applied to the above-mentioned sizing machine and a fume purifier interlocking control method, specifically comprising:

[0032] At least two or more setting machines and oil fume purifiers, wherein each setting machine comprises a plurality of proportional air doors, and a plurality of sensors are arranged on the proportional air doors.

[0033] A further technical solution is that the sensor includes a wind speed sensor, a smoke sensor and a temperature sensor.

[0034] Other features and advantages will be described in the following description. The objects and other advantages of the present invention are realized and obtained by the structures particularly pointed out in the description and drawings.

[0041] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this specification.

[0042] In order to achieve the oil fume cleaning treatment of the setting machine, through the setting of more than two setting machines, an oil fume purifier is provided, and a plurality of proportional dampers are provided in each setting machine, and a plurality of sensors are provided on the proportional dampers. According to the sensing data of the sensor, the damper ratio of the proportional damper of the setting machine is controlled, thereby achieving wind control of the oil fume purifier.

[0043] Setting machines whose oil fume pressure is in a state of concern: Based on the ratio of the cumulative operating time of the setting machines in the preset oil fume pressure range to the cumulative operating time, the operating overlap coefficient of the setting machines is determined, and the setting machines whose operating overlap coefficient is greater than 0.6 are regarded as setting machines whose oil fume pressure is in a state of concern.

[0044] The setting machine whose oil fume pressure is in a state of concern is regarded as a setting machine of concern.

[0045] Purification treatment demand of oil fume purifier: determine the cumulative operating time of different focus setting machines within the preset oil fume pressure range, determine the sum of the cumulative operating time of different focus setting machines based on the cumulative operating time, and use it as the sum of operating time, and determine the purification treatment demand of the oil fume purifier based on the operating time and the corresponding purification treatment demand coefficient.

[0046] Determine that the oil fume purifier does not need to be operated at the maximum wind speed: According to the changes in the monitoring data of the oil fume pressure of different setting machines, determine the change time of the monitoring data corresponding to different setting machines, and determine whether the oil fume purifier needs to be operated at the maximum wind speed based on the proportion of the number of setting machines whose change time accounts for more than 0.3. Specifically, when the proportion of the number of setting machines whose change time accounts for more than 0.3 is more than 0.6, it is determined that the oil fume purifier needs to be operated at the maximum wind speed.

[0047] The wind control result of the fume purifier is determined by the cumulative operating time of the operating range of the fume pressure of different setting machines, and the operating range corresponding to the cumulative operating time ratio is greater than the preset time ratio, and it is used as the commonly used operating range. The wind control result of the fume purifier is determined by the maximum value of the preset wind control amount of different operating ranges corresponding to the commonly used operating range.

[0048] Embodiment 1 To solve the above problem, according to one aspect of the present invention, Figure 1 As shown, a method for controlling a setting machine and a fume purifier in a chain is provided, which specifically includes:

[0049] S1 connects multiple setting machines with the oil fume purifier for processing, and determines the operation overlap with the preset oil fume pressure range according to the monitoring data of the oil fume pressure of different setting machines, and determines whether there is a setting machine with oil fume pressure in a state of concern among the setting machines based on the operation overlap, if yes, proceed to the next step, if not, proceed to step S4;

[0050] Furthermore, multiple setting machines are connected to the oil fume purifier for processing, specifically including:

[0051] After a plurality of setting machines are connected in parallel, they are uniformly connected to the oil fume purifier.

[0052] It can be understood that the preset oil fume pressure range is a pressure range whose deviation from the rated pressure of the setting machine is within a preset deviation range.

[0053] It should be noted that the operation overlap situation includes the number of operations falling within the preset oil fume pressure range and the duration of different operation times.

[0054] It is understandable that if Figure 2 As shown, the method for determining the setting machine whose oil fume pressure is in the state of concern is:

[0055] Based on the operation overlap, determining the cumulative operation time of the setting machine in the preset oil fume pressure range;

[0056] Determining the operation overlap coefficient of the setting machine according to the ratio of the cumulative operation time to the cumulative operation time;

[0057] Whether the setting machine is a setting machine whose oil fume pressure is in a state of concern is determined by the operation overlap coefficient.

[0058] Further, when the operation overlap coefficient of the setting machine is greater than a preset overlap coefficient threshold, it is determined that the setting machine is a setting machine whose oil fume pressure is in a state of concern.

[0059] It should also be noted that the method for determining the setting machine whose oil fume pressure is in a state of concern is:

[0060] Based on the operation overlap, determining the number of times the setting machine operates within the preset oil fume pressure range;

[0061] Determining the screening operation times of the setting machine according to the duration of different operation times;

[0062] Whether the setting machine is a setting machine whose oil fume pressure is in a state of concern is determined by the screening operation times.

[0063] Furthermore, the number of screening runs is the number of runs with a duration within a preset duration interval.

[0064] It should also be noted that when the screening operation times of the setting machine is greater than a preset threshold, the setting machine is determined to be a setting machine with oil fume pressure in a state of concern.

[0065] Optionally, the method for determining the setting machine whose oil fume pressure is in a state of concern is:

[0066] S11, based on the operation overlap, determining the number of times the setting machine operates within the preset oil fume pressure range;

[0067] S12 determines the oil fume operation abnormality coefficients of different operation times according to the duration of different operation times and the oil fume pressure;

[0068] S13 determines the comprehensive abnormality coefficient of the setting machine by using the oil smoke operation abnormality coefficients of different operation times, and determines whether the setting machine is a setting machine in a state of concern according to the comprehensive abnormality coefficient.

[0069] S2 takes the setting machine whose oil fume pressure is in the concerned state as the concerned setting machine, and determines that the purification treatment demand of the oil fume purifier is within the preset demand range based on the monitoring data of the oil fume pressure of different concerned setting machines and the operation overlap of the preset oil fume pressure range, and then proceeds to the next step;

[0070] Specifically, Figure 3 As shown, the method for determining the purification treatment requirements of the oil fume purifier is:

[0071] By focusing on the overlap between the monitoring data of the oil fume pressure of the setting machine and the operation within the preset oil fume pressure range, the cumulative operation time within the preset oil fume pressure range is determined;

[0072] Determine the sum of the accumulated running time of different focus setting machines according to the accumulated running time, and use it as the sum of running time;

[0073] The purification processing requirement of the oil fume purifier is determined according to the operating time.

[0074] Furthermore, the purification processing demand of the oil fume purifier is determined according to the operating time and the corresponding preset demand coefficient.

[0075] It should also be noted that the value range of the purification treatment requirement of the oil fume purifier is between 0 and 1, wherein the higher the purification treatment requirement of the oil fume purifier, the higher the degree of purification treatment requirement of the oil fume purifier.

[0076] It can be understood that when the purification processing demand of the oil fume purifier is not within the preset demand range, it is determined whether the purification processing demand of the oil fume purifier is greater than the preset demand threshold. When the purification processing demand of the oil fume purifier is greater than the preset demand threshold, it is determined that the oil fume purifier needs to operate at the maximum wind force. When the purification processing demand of the oil fume purifier is not greater than the preset demand threshold, it directly enters step S4 to determine the wind force control result of the oil fume purifier.

[0077] It should also be noted that the method for determining the purification treatment requirements of the oil fume purifier is:

[0078] Based on the overlap between the monitoring data of the oil fume pressure of different focus setting machines and the operation within the preset oil fume pressure range, the cumulative operation time of the different focus setting machines within the preset oil fume pressure range is determined;

[0079] Screening the time-limited setting machines among the concerned setting machines according to the accumulated running time;

[0080] The purification processing requirements of the oil fume purifier are determined according to the number of the screening time setting machines.

[0081] Furthermore, the screening time setting machine is a focus setting machine whose cumulative running time is greater than a preset screening time threshold.

[0082] It can be understood that the purification treatment demand of the oil fume purifier is determined according to the ratio of the number of the screening time setting machines to the total number of the setting machines.

[0083] Optionally, the method for determining the purification treatment requirement of the oil fume purifier is:

[0084] S11 determines the cumulative operation time of different concerned setting machines within the preset oil fume pressure range based on the monitoring data of the oil fume pressure of different concerned setting machines and the operation overlap of the preset oil fume pressure range, and determines the initial purification demand coefficient according to the sum of the cumulative operation time of different concerned setting machines;

[0085] S12 obtains the operation time periods of different concerned setting machines within the preset oil fume pressure range, and uses them as the concerned operation time periods, and determines the oil fume abnormality coefficients of different concerned operation time periods by using the oil fume pressures of different concerned setting machines in different concerned operation time periods, and performs overlapping operation demand coefficients by using the oil fume abnormality coefficients of different concerned operation time periods;

[0086] S13 determines the purification processing requirement of the oil fume purifier according to the overlap operation requirement coefficient and the initial purification requirement coefficient.

[0087] Furthermore, the purification treatment demand of the oil fume purifier is determined according to the maximum value of the overlapped operation demand coefficient and the initial purification demand coefficient.

[0088] Optionally, the above step S11 includes steps S111-S113, which are specifically:

[0089] S111 determines the cumulative operation time of different concerned setting machines within the preset oil fume pressure range based on the overlap between the monitoring data of the oil fume pressure of different concerned setting machines and the operation of the preset oil fume pressure range, and when the sum of the cumulative operation time of different concerned setting machines does not meet the requirements, it is directly determined that the oil fume purifier needs to be operated at the maximum wind speed, and when the sum of the cumulative operation time of different concerned setting machines meets the requirements, it goes to step S112;

[0090] S112 selects the time setting machines among the focus setting machines according to the accumulated operation time. When the number of the selected time setting machines does not meet the requirement, it is directly determined that the oil fume purifier needs to run at the maximum wind speed. When the number of the selected time setting machines meets the requirement, the process proceeds to step S113;

[0091] S113 determines the initial purification demand coefficient according to the sum of the accumulated operating time of different focus setting machines, and then proceeds to step S12.

[0092] Optionally, the above step S12 includes steps S121-S123, specifically:

[0093] S121 obtains the operation time periods of different concerned setting machines within the preset oil fume pressure range, and uses them as concerned operation time periods. When the number of concerned operation time periods does not meet the requirement, it is directly determined that the oil fume purifier needs to operate at the maximum wind speed. When the number of concerned operation time periods meets the requirement, it proceeds to step S122;

[0094] S122 determines the oil fume abnormality coefficients of different concerned operation periods by using the oil fume pressures and durations of different concerned setting machines in different concerned operation periods. When there is an concerned operation period in which the oil fume abnormality coefficient does not meet the requirements, the process proceeds to step S123. When there is no concerned operation period in which the oil fume abnormality coefficient does not meet the requirements, the process proceeds to step S124.

[0095] S123: When the number of concerned operation periods in which the oil fume abnormality coefficient does not meet the requirements is greater than the preset number of abnormal operation periods, it is directly determined that the oil fume purifier needs to be operated at the maximum wind speed; when the number of concerned operation periods in which the oil fume abnormality coefficient does not meet the requirements is not greater than the preset number of abnormal operation periods, the process proceeds to step S124;

[0096] S124 performs overlapping operation demand coefficients through the oil fume abnormality coefficients of different focus operation periods. When the overlapping operation demand coefficient does not meet the requirements, it is directly determined that the oil fume purifier needs to operate at the maximum wind speed. When the overlapping operation demand coefficient meets the requirements, it goes to step S13.

[0097] S3 determines the change of the monitoring data of the oil fume pressure of different setting machines based on the monitoring data of the oil fume pressure of different setting machines, and when it is determined that the oil fume purifier does not need to operate at the maximum wind force according to the change, proceeds to the next step;

[0098] Further, determining that the oil fume purifier does not need to operate at the maximum wind speed specifically includes:

[0099] Determine the change time of the oil fume pressure of different setting machines according to the change of the monitoring data of the oil fume pressure of different setting machines;

[0100] Determining the oil smoke fluctuation setting machine in the setting machine according to the number of the change moments;

[0101] Whether the oil fume purifier needs to operate at the maximum wind force is determined by the proportion of the number of the oil fume wave setting machines.

[0102] Specifically, the oil smoke fluctuation shaping machine is a shaping machine in which the proportion of the number of changing moments is greater than the proportion of the number of preset moments.

[0103] It should be noted that when the proportion of the number of the oil fume wave setting machines is greater than the proportion of the number of preset wave setting machines, it is determined that the oil fume purifier needs to operate with the maximum wind speed.

[0104] It should also be noted that determining that the oil fume purifier does not need to operate at the maximum wind speed specifically includes:

[0105] Determine the change time of the oil fume pressure of different setting machines according to the change of the monitoring data of the oil fume pressure of different setting machines. When the number and the change time of the oil fume pressure of different setting machines do not meet the requirements, determine that the oil fume purifier needs to operate at the maximum wind speed;

[0106] When the number of oil fume pressure changes of different setting machines meets the requirements:

[0107] When it is determined by the number of changing moments of the oil fume pressure of different setting machines that there is no setting machine whose number of changing moments does not meet the requirement, it is determined that the oil fume purifier does not need to operate at the maximum wind force;

[0108] When the number of changing moments of the oil fume pressure of different setting machines is used to determine the setting machine whose number of changing moments does not meet the requirements:

[0109] The setting machines whose number at the changing moment does not meet the requirement are regarded as oil fume fluctuation setting machines, and when the number of the oil fume fluctuation setting machines does not meet the requirement, it is determined that the oil fume purifier needs to operate at the maximum wind force;

[0110] When the number of the oil smoke wave setting machines meets the requirements:

[0111] The oil fume fluctuation coefficients of different setting machines are determined based on the number of change moments of different setting machines and the change data of oil fume pressure at different change moments. When the oil fume fluctuation coefficients of different setting machines are all within the preset fluctuation coefficient range:

[0112] It is determined that the oil fume purifier does not need to be operated at the maximum wind speed;

[0113] When there is a setting machine whose oil smoke fluctuation coefficient is not within the preset fluctuation coefficient range:

[0114] The setting machines whose oil fume fluctuation coefficient is not within the preset fluctuation coefficient range are regarded as fluctuation abnormal setting machines. When the number of fluctuation abnormal setting machines does not meet the requirement, it is determined that the oil fume purifier needs to operate at the maximum wind speed;

[0115] When the number of the abnormal fluctuation setting machines meets the requirement:

[0116] The comprehensive fluctuation coefficient of the setting machine is determined by using the oil fume fluctuation coefficients of different setting machines, and whether the oil fume purifier needs to operate at the maximum wind force is determined according to the comprehensive fluctuation coefficient.

[0117] S4 determines the operating ranges of the oil fume pressures of different setting machines based on the analysis results of the monitoring data of the oil fume pressures of different setting machines, and outputs the wind force control results of the oil fume purifier based on the operating ranges of the oil fume pressures of different setting machines.

[0118] Specifically, Figure 4 As shown, the method for outputting the wind control result of the oil fume purifier is:

[0119] Determine the oil fume pressure of different setting machines at different operating moments based on the operating range of the oil fume pressure of different setting machines, and determine the oil fume pressure and of different operating time by the oil fume pressure at different operating moments;

[0120] According to the oil smoke pressure of different operating time, the accumulated operating time in different operating intervals is determined, and the operating interval range corresponding to the accumulated operating time ratio greater than the preset time ratio is determined through the accumulated operating time of different operating intervals, and it is used as the common operating interval range;

[0121] The wind force control result of the oil fume purifier is outputted through a commonly used operating range.

[0122] Furthermore, the wind force control result of the oil fume purifier is outputted through a commonly used operating range, specifically including:

[0123] The wind force control result of the oil fume purifier is determined by the maximum value of the preset wind force control amount in different operating intervals corresponding to the commonly used operating interval range.

[0124] It should also be noted that the above step S11 includes steps S111-S113, which are specifically:

[0125] S111 determines the cumulative operation time of the setting machine within the preset oil fume pressure range based on the operation overlap situation. When the cumulative operation time of the setting machine within the preset oil fume pressure range is greater than the preset cumulative time, the setting machine is determined to be a setting machine in a state of concern. When the cumulative operation time of the setting machine within the preset oil fume pressure range is not greater than the preset cumulative time, the process proceeds to step S112.

[0126] S112: When the cumulative operation time of the setting machine within the preset oil fume pressure range is within the preset operation time interval, the process proceeds to step S113; if not, the operation times of the setting machine within the preset oil fume pressure range are determined based on the operation overlap, and the process proceeds to step S12;

[0127] S113 determines the number of times the molding machine operates within the preset oil fume pressure range based on the operation overlap. When the number of operations is greater than the preset operation number threshold, the molding machine is determined to be a molding machine in a state of concern. When the number of operations is not greater than the preset operation number threshold, the process proceeds to step S12.

[0128] It should also be noted that before entering step S12, it is also necessary to determine whether the cumulative operating time of the molding machine whose oil fume pressure is greater than the preset oil fume pressure is greater than the preset time threshold. When the cumulative operating time of the molding machine whose oil fume pressure is greater than the preset oil fume pressure is greater than the preset time threshold, the molding machine is determined to be a molding machine in the focus state. When the cumulative operating time of the molding machine whose oil fume pressure is greater than the preset oil fume pressure is not greater than the preset time threshold, proceed to step S12.

[0129] It should also be noted that the above step S12 includes steps S121-S123, which are specifically:

[0130] S121 determines the screening operation times of the setting machine according to the duration of different operation times. When the screening operation times are greater than a preset number threshold, the setting machine is determined to be a setting machine in a concerned state. When the screening operation times are not greater than the preset number threshold, the process proceeds to step S122.

[0131] S122 determines the oil fume operation abnormality coefficients of different operation times according to the duration of different operation times and the oil fume pressure. When the oil fume operation abnormality coefficients of different operation times are all within the preset coefficient range, it is determined that the setting machine does not belong to the setting machine in the concerned state. When there is an operation time when the oil fume operation abnormality coefficient is not within the preset coefficient range, enter step S123;

[0132] S123 takes the number of operations in which the oil fume operation abnormality coefficient is not within the preset coefficient range as the number of oil fume operation abnormalities. When the number of oil fume operation abnormalities is greater than the preset abnormal number threshold, it is determined that the molding machine belongs to the molding machine in the attention state. When the number of oil fume operation abnormalities is not greater than the preset abnormal number threshold, it goes to step S13.
