[0045] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0046] The present application provides an automatic start-stop and temperature control combined control method of a high-temperature cleaning equipment, referring to Figure 1 , Figure 1 Figure 4 is a structural schematic view of an automatic start-stop and temperature control combined control device of a high-temperature cleaning equipment according to an embodiment of the present application; Figure 1 as shown, comprising the following steps:

[0047] Step 101, automatically starting a vacuum pump included in the high-temperature cleaning equipment, so that the vacuum pump performs vacuumizing treatment on the internal cavity, under the condition that the spinning assembly to be cleaned is located in the internal cavity of the high-temperature cleaning equipment.

[0048] In the present application, the high-temperature cleaning equipment includes an equipment main body and a plurality of auxiliary assemblies for assisting the equipment main body to clean the polymer, wherein the equipment main body can be approximately understood as a vacuum furnace, and the internal cavity is formed in the vacuum furnace, and the spinning assembly will be located in the internal cavity during the cleaning process of the spinning assembly.

[0049] The aforementioned vacuum pump is one of the plurality of auxiliary assemblies.

[0050] The aforementioned spinning assembly to be cleaned can be any assembly that can be contaminated by the polymer during the spinning process, such as a spinneret, a filter element, etc.

[0051] When it is detected that the spinning assembly to be cleaned (which needs to be disassembled from the spinning equipment) is placed in the internal cavity of the high-temperature cleaning equipment, and the internal cavity is completely closed (i.e., the cover is completely closed), the starting event of the vacuum pump is triggered to start the vacuum pump to perform vacuumizing treatment on the internal cavity.

[0052] Exemplarily, the above detection can be completed by means of gravity detection or computer vision detection, for example: detecting whether the weight of the equipment region corresponding to the internal cavity exceeds a preset weight threshold, if yes, it is determined that the spinning assembly to be cleaned has been placed in the internal cavity of the high-temperature cleaning equipment, otherwise, it is determined that the spinning assembly to be cleaned has not been placed in the internal cavity of the high-temperature cleaning equipment; or, collecting an image of the equipment region corresponding to the internal cavity, and taking the spinning assembly to be cleaned as a detection target, performing target detection on the collected image, and determining whether the spinning assembly to be cleaned is placed in the internal cavity of the high-temperature cleaning equipment according to the result of target detection.

[0053] Step 102, monitoring the vacuum degree of the internal cavity based on the first sensing component included in the high-temperature cleaning equipment, and automatically starting the temperature raising component included in the high-temperature cleaning equipment when the vacuum degree matches a preset vacuum condition, so that the temperature raising component performs temperature raising processing on the internal cavity.

[0054] The degree of vacuum refers to the degree that the gas pressure in a closed system (i.e. the internal cavity in the present application) is lower than the standard atmospheric pressure, which is usually expressed by pressure value or relative percentage. The higher the degree of vacuum, the thinner the gas molecules in the closed system.

[0055] Step 103, monitoring the temperature of the internal cavity based on the temperature sensor included in the high-temperature cleaning equipment, and automatically closing the temperature raising component and automatically starting the constant temperature component included in the high-temperature cleaning equipment when the temperature is greater than or equal to a preset temperature threshold, so that the constant temperature component controls the temperature of the internal cavity within a preset constant temperature interval.

[0056] It should be understood that the constant temperature interval is an interval in which the high-molecular polymer (such as polyester) adhered to the spinning assembly to be cleaned is quickly decomposed into volatile substances (such as CO2, H2O, etc.). For example, the constant temperature interval can be [495℃-505℃].

[0057] It should be noted that during the operation of the temperature raising component or the constant temperature component, the vacuum pump is also in operation to remove the volatile substances decomposed from the high-molecular polymer, so as to prevent secondary deposition of pollutants.

[0058] Step 104, monitoring the cleaning degree of the spinning assembly to be cleaned based on the second sensing component included in the high-temperature cleaning equipment, and automatically closing the constant temperature component when the cleaning degree matches a preset cleaning condition.

[0059] It should be understood that when the thermostat assembly is closed, the vacuum pump is also closed accordingly, and after the temperature of the internal cavity drops to room temperature, the user is allowed to open the cover of the device body to take out the cleaned spinning assembly.

[0060] In the present application, whether the internal cavity of the high-temperature cleaning device has a spinning assembly to be cleaned, the vacuum degree, and the temperature, and the preset conditions are combined to automatically trigger the start of the vacuum pump, the start and stop of the temperature raising assembly, and the start and stop of the thermostat assembly, so as to replace the manual control of the functions used in the related art by automatic control, thereby avoiding the interference of human factors, and enabling the spinning assembly to stably obtain the expected cleaning effect after being cleaned by the high-temperature cleaning device.

[0061] In one embodiment, the first sensing assembly and the second sensing assembly are the same assembly, and the first sensing assembly is a timer, which is used to record the running time of the vacuum pump.

[0062] In the case where the running time of the vacuum pump is greater than or equal to a preset first time threshold, it is determined that the vacuum degree matches the preset vacuum condition.

[0063] In the case where the running time of the vacuum pump is greater than or equal to a preset second time threshold, it is determined that the cleaning degree matches the preset cleaning condition.

[0064] In the case where the running time of the vacuum pump is greater than or equal to a preset second time threshold, it is determined that the cleaning degree matches the preset cleaning condition.

[0065] In this embodiment, the first sensing assembly and the second sensing assembly are combined into the same assembly, and the assembly is set as a timer, so as to monitor whether the preset vacuum state (i.e., the vacuum degree matches the preset vacuum condition) is reached in the target cavity and whether the cleaning target of the spinning assembly to be cleaned is completed (i.e., the cleaning degree matches the preset cleaning condition) by recording the running time of the vacuum pump, which can reduce the equipment cost of the high-temperature cleaning device and simplify the control logic of the vacuum pump, the thermostat assembly, etc., thereby improving the cleaning effect of the spinning assembly and the reliability of the implementation of the present application.

[0066] For example, the first time threshold and the second time threshold can be refined by collecting operation data (at least including the vacuum pumping time of the vacuum pump, the total running time of the vacuum pump, and the cleaning degree of the spinning assembly) during manual operation and analyzing the three.

[0067] In one embodiment, the method further comprises:

[0068] The temperature of the internal cavity is monitored based on a temperature sensor comprised in the high-temperature cleaning device, and when the temperature is greater than or equal to a preset temperature threshold, a water pump comprised in the high-temperature cleaning device is automatically started to supply water to the internal cavity.

[0069] The cleaning degree of the spinning assembly to be cleaned is monitored based on a second sensing component comprised in the high-temperature cleaning device, and when the cleaning degree matches a preset cleaning condition, the water pump is automatically turned off to stop the water supply to the internal cavity.

[0070] In this embodiment, the water pump is also included in the automatic control management category, and the replacement of manual operation is also realized as much as possible, thereby reducing the labor cost when the method is applied, and improving the cleaning effect of the spinning assembly.

[0071] The water provided by the water pump is used to accelerate the cracking of the aforementioned high molecular polymer and keep the temperature uniform in the internal cavity.

[0072] In one embodiment, the step of heating the internal cavity includes:

[0073] The internal cavity is gradually heated based on a plurality of preset continuous heating intervals, wherein the higher the temperature indicated by the center point of the heating interval, the lower the heating rate of the internal cavity in the corresponding heating interval.

[0074] Based on the above setting, the heating rate of the internal cavity is gradually reduced during the process of heating the internal cavity to the temperature threshold, so as to cooperate with the water pump to keep the temperature of the internal cavity uniform during the heating process, thereby avoiding the problem of excessive temperature difference between different positions in the internal cavity caused by too fast temperature rise, and carbonization of the high molecular polymer to be cleaned in some areas.

[0075] In one example, the heating assembly can include a resistance wire arranged around the inner wall of the internal cavity, and in this example, the heating rate can be adjusted by adjusting the current flowing through the resistance wire.

[0076] The rising heating rate can be understood as the heating amplitude in the internal cavity per unit time, for example, 1 degree Celsius per minute.

[0077] Further, the higher the temperature indicated by the center point of the heating interval, the smaller the interval width in the corresponding heating interval.

[0078] As the temperature in the internal cavity gradually increases, by setting a smaller interval width to provide more refined temperature control means in the later stage of temperature rise (compared to the early stage of temperature rise), by further slowing down the temperature rise rate in the process of the internal cavity about to rise to the temperature threshold, the temperature of different positions in the internal cavity can be guaranteed to rise to the set temperature threshold at the same time as much as possible.

[0079] For example, the temperature threshold can be 500 degrees Celsius, and the plurality of continuous temperature rise intervals can be [0℃, 200℃], (200℃, 350℃], (350℃, 420℃], (420℃, 470℃], (470℃, 500℃].

[0080] In one embodiment, the high-temperature cleaning device further comprises a gas pump for providing inert gas, and the output end of the gas pump is arranged in the internal cavity.

[0081] The step of vacuumizing the internal cavity comprises:

[0082] The vacuum pump is controlled to vacuumize the internal cavity at a first power;

[0083] When the vacuum degree of the internal cavity is greater than or equal to a first threshold, the vacuum pump is controlled to vacuumize the internal cavity at a second power, and the gas pump is automatically triggered to continuously output inert gas to the internal cavity, and the flow of the inert gas output by the gas pump is calculated based on a PID algorithm, and the PID algorithm is used to control the vacuum degree of the internal cavity to gradually increase.

[0084] When the vacuum degree of the internal cavity is greater than or equal to a second threshold, the vacuum pump is controlled to vacuumize the internal cavity at a third power, and the gas pump is automatically triggered to periodically output inert gas to the internal cavity, wherein the first power is greater than the second power, the second power is greater than the third power, and the first threshold is less than the second threshold.

[0085] The stage (one stage, the vacuum degree of the internal cavity is less than the first threshold) of controlling the vacuum pump to vacuumize the internal cavity at a first power can be understood as within 0~N1 seconds (N1 can be 60) after the vacuum pump is started, the vacuum pump in one stage is vacuumized by taking a high gear power (i.e. the first power) to quickly increase the vacuum degree in the internal cavity, and at this time the gas pump is not working to avoid the gas pump affecting the work of the vacuum pump in one stage.

[0086] In the case that the vacuum degree of the internal cavity is greater than or equal to the first threshold value (the second stage), it can be understood that the vacuum pump is started for N1-N2 seconds (N2 can be 240), and the vacuum pump is used to perform vacuum pumping at a medium power (i.e., the second power) in the second stage, so that the vacuum degree in the internal cavity is increased smoothly. At this time, the air pump is working and continuously outputs inert gas to cooperate with the vacuum pump to smoothly increase the vacuum degree in the internal cavity in the second stage. The inert gas is used to protect the high-temperature cracking of the polymer in the subsequent process, inhibit oxidation or carbonization, and is used to cooperate with the vacuum pump to discharge the oxygen and other gases in the internal cavity that may interfere with the cracking of the polymer.

[0087] In the case that the vacuum degree of the internal cavity is greater than or equal to the second threshold value (the third stage), it can be understood that the vacuum pump is started for N2 seconds, and the vacuum pump is used to perform vacuum pumping at a low power (i.e., the third power) in the second stage, so that the vacuum degree in the internal cavity is stably maintained in a preset interval range. At this time, the air pump is periodically working to periodically output inert gas, and the protection of the high-temperature cracking process of the polymer in the subsequent process is maintained without causing the vacuum degree to decrease.

[0088] The above-mentioned inert gas can be nitrogen or argon.

[0089] The feedback adjustment logic of the PID algorithm control of the air pump output can be that when the growth rate of the vacuum degree of the internal cavity (detected by the vacuum gauge) is lower than the set rate threshold, the flow rate of the air pump per unit time is reduced, and otherwise, the flow rate of the air pump per unit time is increased.

[0090] Based on the above settings, the oxidation or carbonization of the polymer can be inhibited, the time consumption of the vacuum pump for vacuumizing the internal cavity can be shortened, that is, the time consumption from the start of the vacuum pump to the matching of the vacuum degree of the internal cavity to the preset vacuum condition can be shortened, the energy consumption can be reduced, and the cleaning efficiency of the spinning assembly can be improved.

[0091] In an embodiment, in the case that the spinning assembly to be cleaned is a spinneret and the spinning assembly to be cleaned is located in the internal cavity of the high-temperature cleaning device, the spinning assembly to be cleaned covers the output end of the air pump.

[0092] In this embodiment, for the case that the spinning assembly to be cleaned is a spinneret, the spinning assembly to be cleaned is arranged to cover the output end of the air pump, so that the spinneret is used as a guide plate of the output end of the air pump, the inert gas output by the air pump is prevented from directly flowing into the inlet of the vacuum pump, and the inert gas provided by the air pump can be uniformly distributed in the internal cavity, so that the effect of the inert gas can be effectively exerted.

[0093] Further, the second sensing component is a timer, which is configured to record the running time of the vacuum pump.

[0094] The method further comprises:

[0095] In a case where the running time of the vacuum pump is greater than or equal to a preset second time threshold, and the pressure drop of the inert gas output by the output end of the air pump passing through the spinning assembly to be cleaned is less than a pressure drop threshold, it is determined that the cleaning degree matches the preset cleaning condition.

[0096] In a case where the spinning assembly to be cleaned is a spinneret, the pressure drop of the inert gas output by the output end of the air pump passing through the spinning assembly to be cleaned is further detected, and the pressure drop is also taken into account as a consideration index of the cleaning condition, so as to adapt to the case where, in addition to the surface-attached high molecular polymer, the spinneret hole is also attached with high molecular polymer, and the cleaning of the high molecular polymer attached in the spinneret hole is more difficult, thereby being able to more accurately determine whether the cleaning degree of the spinneret matches the preset cleaning condition.

[0097] Specifically, the greater the pressure drop of the inert gas output by the output end of the air pump passing through the spinning assembly to be cleaned, the greater the resistance of the inert gas output by the output end of the air pump passing through the spinneret, that is, it is indicated that there is still more high molecular polymer attached in the spinneret hole.

[0098] In one example, the present application also provides an automatic start-stop and temperature control combined control system, as shown in Figures 2-4 The system comprises a control button, a coil, a temperature controller, a heating element and other auxiliary components.

[0099] In the attached Figures 2-4 , the calcination chamber is shown by mark 10, the main heating loop is shown by mark 20, the auxiliary heating loop is shown by mark 30, the water inlet pipe is shown by mark 40, the water outlet pipe is shown by mark 50, and the water pump motor is shown by mark 60.

[0100] The control button comprises: SB1-SB4.

[0101] The button SB1 is a normally closed button, which can be manually stopped by the user to stop the entire system running, and after being pressed, the corresponding control loop is cut off to stop the system working.

[0102] The button SB2 is a normally open button, which is pressed to start the system and provide an initial control signal for the system running, and the related control circuit is turned on.

[0103] The button SB4 is a normally open button, which is specially used to start the heating function, and after being pressed, the control logic related to heating is triggered to make the heating circuit (i.e. the circuit corresponding to the temperature increasing component and the temperature maintaining component) work.

[0104] The button SB3 is used for switching between the manual control mode and the automatic control mode of the water source, and changing the connection state of the water source (i.e. the water pump) control circuit.

[0105] The coils include SK coils, KA1-KA4 coils, and KM1-MK3 coils.

[0106] The SK coils are execution coils associated with the SK time controller and are controlled by the internal time logic of the SK time controller. When the preset start time is reached, the SK time controller triggers the SK coils to be powered on to perform the start action; when the preset stop time is reached, the SK coils are powered off to perform the stop action.

[0107] The SK time controller is an automatic control switch with a time control function. By presetting time parameters (such as daily operation period, timing start and stop time, etc.), the device can be automatically controlled according to the time logic without human intervention.

[0108] The KA1 coil is an intermediate relay coil. When powered on, its contact acts to control the on-off of other circuits, realizing signal amplification and conversion.

[0109] The KA2 coil is controlled by the temperature controller PXF9. When powered on, it performs auxiliary control actions related to the main heating.

[0110] The KA3 coil triggers the stop-related control logic when powered on, which can be used to cut off the heating or other running circuits to realize the stop function.

[0111] The KA4 coil is controlled by the heating start button SB4 and the temperature controller PXF5. When powered on, it controls the related actions of the auxiliary heating circuit.

[0112] The KM1 coil is an AC contactor coil. When powered on, the main contact is closed to provide a power supply path for the PT100 main heating.

[0113] The KM2 coil is an AC contactor coil. When powered on, it controls the power on-off of the auxiliary heating or related circuits.

[0114] The KM3 coil is an AC contactor coil. In the water source control logic, it controls the water source-related circuits according to the manual / automatic state.

[0115] The temperature controller includes the PXF9 temperature controller (which can be understood as the aforementioned temperature rising component) and the PXF5 temperature controller (which can be understood as the aforementioned constant temperature component).

[0116] The PXF9 temperature controller monitors the temperature and controls the on-off of the KA2, KA3, etc. coils according to the comparison result of the set temperature value and the actual temperature, realizing the main heating control and related stop logic.

[0117] PXF5 temperature control: monitor another temperature, according to the temperature, cooperate with SB4 heating start button control KA4 coil, and then control PT100 auxiliary heating.

[0118] The heating element includes PT100 main heating and PT100 auxiliary heating.

[0119] Among them, PT100 main heating: main heating resistance, when KM1 coil is powered, the main contact is closed, the circuit is connected to start heating, and the system temperature is raised.

[0122] Among them, UD indicator light: power indicator light, which lights up when the system is powered on, indicating that the system is in an electrified state.

[0123] Temperature sensor: detects temperature signal and feeds back to temperature controller to provide actual temperature data for temperature controller to realize temperature closed-loop control.

[0124] It should be noted that, Figure 3 A, B, C represent three phase lines (also called live lines) of three-phase alternating current power with different phases (the phases are 120° apart in turn), which provide three-phase power for subsequent main heating (KM1), auxiliary heating (KM2), water pump motor (KM3) and other devices, ensuring stable operation of the system in three-phase power supply mode.

[0125] The operation logic of the system is as follows:

[0126] (1) System startup

[0127] Press SB2 system start button, KA1 coil is powered, KA1 contact is actuated, and initial path is provided for subsequent control circuit. At the same time, UD indicator light is lit, indicating that the system has been powered on. At this time, SK time control starts to run internal timing logic, and if the current time meets the preset automatic start period, SK time control triggers SK coil to be powered, further maintaining system operation logic (if the preset time is not reached, SK coil does not act, and the system only remains powered on standby, without executing subsequent heating and other actions).

[0128] (2) Main heating control

[0129] 1. PXF9 temperature controller receives temperature signal feedback from temperature sensor in real time. When the actual temperature is lower than the set temperature, PXF9 temperature controller controls KA2 coil to be powered, triggering related control logic.

[0130] 2. After KA2 action, if the condition is met, KM1 coil is energized, its main contact is closed, PT100 main heating circuit is connected to start heating. With the temperature rising, when reaching the upper limit temperature value set by PXF9 temperature controller, KA3 coil is energized by PXF9 control, KA3 contact is actuated to cut off KM1 coil circuit, and main heating is stopped.

[0131] (Three) Auxiliary heating control

[0132] Press SB4 heating start button, KA4 coil has energized condition. At this time, PXF5 temperature controller judges according to the temperature feedback signal of temperature sensor. If the temperature does not meet the auxiliary heating start condition, KA4 does not act. If the temperature meets the condition, PXF5 controls KA4 coil to be energized, and then makes the related circuit conductive, PT100 auxiliary heating circuit auxiliary heating.

[0133] (Four) Water source control

[0134] Switch the water source control mode through SB3 water source manual / automatic button:

[0135] Manual mode: SB3 is switched to manual position to directly control KM3 coil related circuit, and water source on-off is manually controlled.

[0136] Automatic mode: SB3 is switched to automatic position, and the system controls KM3 coil on-off through KA3 and KA4 relay contact cooperation according to temperature sensor signal and related control logic (such as temperature reaching a certain value to start water source), to realize automatic control of water source.

[0137] (Five) System stop

[0138] 1. Manual stop: press stop SB1 button to cut off KA1 coil circuit, reset KA1 contact, and then cut off other related control circuits, so that all heating, water source and other running circuits stop working, and the system stops running.

[0139] 2. Time control stop: when SK time control runs to the preset stop time point, SK coil loses power, KA3 coil (stop) is energized, KA3 contact is actuated to cut off heating and other running circuits, and the system is automatically stopped according to time logic. In addition, KA3 coil (stop) can also be triggered to stop action by temperature and other logic.

[0140] The system has the following advantages:

[0141] 1. Integrated SK time control automatic start-stop logic, time parameters can be preset, equipment can be accurately started and stopped according to time logic, no need for real-time manual monitoring, greatly improving the automation level of the system, especially suitable for industrial or civil scenes that need to be operated at regular intervals, reducing labor costs and improving management efficiency.

[0142] 2. Two temperature controllers (PXF9 and PXF5) are used to monitor the temperature, combined with main and auxiliary heating elements (PT100 main heating, PT100 auxiliary heating), which can flexibly switch heating modes according to the difference between actual temperature and set value, realize precise temperature control, meet the requirements of temperature stability and precision in different scenes, and improve heating efficiency and effect.

[0143] 3. The intermediate relay (KA1, etc.) is used for signal amplification and conversion to ensure the stability of the control signal; KA3 coil (stop) and other elements form multiple stop logic, which can cut off the circuit through manual button, temperature trigger or time control logic to ensure safe shutdown of the system, prevent abnormal operation and improve the overall reliability and stability of the system.

[0144] 4. The UD indicator light is used to directly display the power-on state of the system, and the control buttons (SB1, SB2, etc.) are arranged clearly and are easy to operate.
