Detailed Description

In order to make the technical solutions of the present application better understood by those skilled in the art, 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, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; may be mechanically, electrically or may be in communication with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

In the description of the present application, "a plurality" means two or more unless specifically limited otherwise. Furthermore, the terms "comprises" and any variations thereof, are intended to cover non-exclusive inclusions. For example, a system, product, or device that comprises a list of modules is not limited to only the modules listed, but may alternatively include modules not listed, or may alternatively include other modules inherent to such product or device.

Referring to fig. 1, fig. 1 illustrates a processing liquid temperature control device 100 according to an embodiment of the present disclosure. The processing fluid temperature control apparatus 100 may be applied to an industrial production line for heating and monitoring the temperature of the processing fluid under a safe operation. The working fluid is a fluid used for lubricating and cooling a working tool and a working member during a product working process. The working fluid may be a metal working fluid, such as a cutting fluid specifically used for cutting, a grinding fluid used for grinding, or the like.

As shown in fig. 1, the processing liquid temperature control device 100 includes a heating unit 10. The heating unit 10 is used for supplying and heating the machining fluid, and supplying the heated machining fluid.

Specifically, the heating unit 10 may include a body 11, an inlet port 13, an outlet port 14, and a heater 15.

Wherein, the body 11 is solid. The interior of the body 11 is provided with a passage 12. It will be appreciated that the channel 12 is a recess in the interior of the body 11 which can be used to transport the process fluid. The passage 12 penetrates the surface of the body 11 such that the surface of the body 11 is formed with a plurality of openings (not shown) as connection ends of the passage 12 for connecting other components. The openings of the channel 12 communicate. The body 11 is further provided with a mounting groove (not shown) therein, and the mounting groove also penetrates the surface of the body 11. The mounting groove does not communicate with the passage 12. It is to be understood that the present application is not limited to the shape of the body 11. For example, in some embodiments, referring to fig. 2 and 3, the body 11 may be a hollow rectangular parallelepiped.

The body 11 is a heat conductor, and for example, a metal block (for example, an aluminum block) may be used. The body 11 may function to conduct heat.

Referring to fig. 2 and fig. 3, the liquid inlet 13 and the liquid outlet 14 are both disposed on the surface of the body 11 and are respectively located at corresponding openings on the surface of the body 11, and the liquid inlet 13 and the liquid outlet 14 can thus communicate with the channel 12.

The inlet port 13 and the outlet port 14 can be used to communicate with the processing fluid collection end 200 (shown in fig. 1). The processing liquid collecting terminal 200 stores the processing liquid. When the inlet port 13 and the outlet port 14 are communicated with the processing liquid collecting end 200, the channel 12 can be in fluid circulation connection with the processing liquid collecting end 200 through the inlet port 13 and the outlet port 14. Therefore, the processing fluid in the processing fluid collecting end 200 can flow to the channel 12 through the inlet port 13, and the processing fluid in the channel 12 flows back to the processing fluid collecting end 200 through the outlet port 14.

The heater 15 is installed and fixed in the installation groove of the body 11. The electrical connector 151 of the heater 15 may extend out of the body 11 (see fig. 3) to electrically connect other components. The heater 15 may be used to generate heat when energized. It will be appreciated that since the body 11 is capable of conducting heat, the heat generated by the heater 15 can be transferred through the body 11 to the process fluid in the channel 12, thereby effecting heating of the process fluid in the channel 12.

It is to be understood that the present application is not limited to the type of heater 15. As an example, the heater 15 may employ an electric heating rod.

It is to be understood that the present application is not limited to the number and installation positions of the heaters 15. For example, the heater 15 may be disposed in a plurality and distributed around the channel 12, so that the heat generated by the heater 15 can be quickly transferred to the channel 12, and the heat dissipation can be reduced.

In some embodiments, referring to fig. 5 and 6, in order to improve the heating efficiency of the heater 15, the channels 12 may be arranged in multiple rows and multiple columns, so as to improve the distribution density of the channels 12 in the body 11, so that the heat generated by the heater 15 can be more transferred to the channels 12 and absorbed by the processing fluid in the channels 12. It will be appreciated that the channels 12 in different rows and columns may be in communication with each other so that the temperature of the heating fluid in the channels 12 may be uniform.

It will be appreciated that when the heater 15 is provided in plural, the plural heaters 15 may be uniformly distributed between the channels 12 of different rows and different columns, that is, the channels 12 of each row and each column are at the same distance from the nearest heater 15, so that the heaters 15 can heat the heating liquid in the channels 12 more uniformly.

It will be appreciated that the channels 12 of each row and each column may extend through the surface of the body 11 and form corresponding openings. Therefore, in practical use, two of the openings on the surface of the body 11 can be flexibly selected according to practical situations to install the liquid inlet port 13 and the liquid outlet port 14, so that the connection between the channel 12 and the liquid inlet port 13 and the liquid outlet port 14 is very flexible and convenient. It is understood that, as shown in fig. 2 and 3, the opening not connected to the inlet port 13 and the outlet port 14 may be provided with a cap 16 to close the opening and prevent the processing fluid from flowing out of the opening.

Referring again to fig. 1, the heating unit 10 may further include a regulating valve 17. The regulating valve 17 is provided at least one of the inlet port 13 and the outlet port 14. It can be understood that the flow rate of the processing fluid flowing into the inlet port 13 can be changed by changing the open/close state of the regulating valve 17 mounted on the inlet port 13, and the flow rate of the processing fluid flowing out of the outlet port 14 can be changed by changing the open/close state of the regulating valve 17 mounted on the outlet port 14. It is understood that the present application is not limited to the type of the regulating valve 17, for example, the regulating valve 17 may be a solenoid valve or other electrically connectable and controllable valve.

It is understood that a fluid pump 201 (shown in fig. 1) may be further installed in the processing fluid collecting port 200 to accelerate the circulation of the processing fluid. The inlet port 13 is connected to the outlet of the liquid pump 201, and the outlet port 14 is connected to the inlet of the liquid pump 201. After the liquid pump 201 is powered on to work, the processing liquid to be heated in the processing liquid collecting end 200 can be pumped to the liquid inlet interface 13 through the outlet of the liquid pump 201, and the processing liquid flows into the channel 12 through the liquid inlet interface 13 and is heated by the heater 15. The heated processing fluid in the channel 12 flows back to the processing fluid collecting end 200 through the fluid outlet port 14 and the inlet of the fluid pump 201, and the above-mentioned steps are repeated in this way, so that the temperature of the processing fluid can be kept at a certain temperature value or within a certain temperature range.

Referring to fig. 4, to facilitate moving the heating unit 10, the heating unit 10 may be mounted on a substrate 30. The base plate 30 is provided with rollers so that movement can be very conveniently performed.

Referring again to fig. 4, the heating unit 10 may further include a shield 18. The shield 18 is mounted on the substrate 30 and surrounds the body 11 together with the substrate 30. The shield 18 may be spaced from the body 11. The shield 18 protects the body 11 and also reduces the heat dissipation from the body 11. The protective cover 18 is provided with a through slot (not numbered), and the size of the through slot is larger than that of the liquid inlet port 13 and larger than that of the liquid outlet port 14, so that the liquid inlet port 13 and the liquid outlet port 14 can penetrate through the through slot, and the protective cover 18 covers the heating unit 10 and does not hinder the connection between the heating unit 10 and the processing liquid collecting end 200. The shield 18 is perforated with perforations (not numbered) that facilitate electrical connection between the electrical connector 151 of the heater 15 in the heating unit 10 and other components outside the shield 18.

Referring again to fig. 2 and 3, the heating unit 10 may further include a heat insulation member 19. The body 11 is mounted on the base plate 30 by the thermal insulation 19, i.e. the thermal insulation 19 is located between the base plate 30 and the body 11. It will be appreciated that the thermal shield 19 may separate the substrate 30 from the body 11, which may reduce the amount of heat transferred from the heater 15 through the body 11 to the substrate 30 and the shield 18, thereby reducing heat loss from the heating unit 10, and may also prevent the temperature of the substrate 30 from increasing and affecting the life of other components mounted on the substrate 30.

It is to be understood that the present application is not limited to the specific configuration of the thermal shield 19. For example, the thermal insulation 19 may include a support 191 and a thermal insulation layer 192, and the thermal insulation layer 192 may be made of thermal insulation cotton, for example. The support 191 is mounted on the substrate 30, the thermal insulation layer 192 is located between the support 191 and the body 11, and the support 191 can support the body 11 so that a certain distance exists between the body 11 and the substrate 30 to reduce the speed of transferring heat generated by the heater 15 to the substrate 30 through the body 11. The thermal insulation layer 192 has a low thermal conductivity and can serve as thermal insulation.

Referring to fig. 1 again, the processing liquid temperature control apparatus 100 further includes a detection unit 20. Specifically, the detection unit 20 includes a first temperature sensor 21, a second temperature sensor 22, and a flow sensor 23. The first temperature sensor 21 is disposed on the body 11, the first temperature sensor 21 can be used for detecting the temperature of the body 11, and the temperature of the body 11 is the temperature of the heating unit 10. A second temperature sensor 22 is disposed on the outlet port 14, and the second temperature sensor 22 is used for detecting the temperature of the processing liquid flowing out of the heating unit 10. The flow sensor 23 is disposed on the inlet port 13, and the flow sensor 23 can be used to detect the flow rate of the processing liquid flowing into the heating unit 10.

Referring to fig. 1 again, the processing liquid temperature control apparatus 100 further includes a control unit 40. The control unit 40 serves as a control center of the entire processing liquid temperature control apparatus 100. Specifically, referring to fig. 5 and 6 together, the control unit 40 may include a housing 41 and a controller 42. The cover 41 is mounted on the base plate 30. The controller 42 is housed in the housing 41. The controller 42 may be a general purpose Central Processing Unit (CPU), a microprocessor, an application-specific integrated circuit (ASIC), or one or more integrated circuits. The housing 41 is provided with a through-groove (not numbered), so that the controller 42 can be electrically connected to other components (e.g., the heating unit 10) outside the housing 41 through the through-groove. The surface of the housing 41 may also be provided with a switch button (not shown) and/or a display screen (not shown), both of which may be connected to the controller 42. The switch buttons may facilitate manual activation and deactivation of controller 42 by a worker. The display screen may display corresponding content under the control of the controller 42.

The controller 42 is connected to the detection unit 20, and thus, the controller 42 may receive the machining fluid flow rate, the temperature of the heating unit 10, and the machining fluid temperature from the detection unit 20.

The controller 42 is also connected to the regulator valve 17, and therefore, the controller 42 can control the open-closed state of the regulator valve 17.

The controller 42 is also connected to the liquid pump 201, and thus, the controller 42 can control whether the liquid pump 201 is activated.

It is understood that when the housing 41 is provided with a display screen on the surface thereof, the controller 42 can also control the display screen to display the flow rate of the processing liquid, the temperature of the heating unit 10, the temperature of the processing liquid, the open/close state of the regulating valve 17, and the operating state of the liquid pump 201, so as to be known by the operator.

The controller 42 is also connected to the heating unit 10. It is understood that the flow rate of the machining fluid flowing into the heating unit 10, the temperature of the heating unit 10, and the temperature of the machining fluid flowing out of the heating unit 10 are all associated with the operation of the heating unit 10, and thus the controller 42 can confirm whether the heating unit 10 operates normally according to the flow rate of the machining fluid, the temperature of the heating unit 10, and the temperature of the machining fluid. And controls the heating operation of the heating unit 10 according to the flow rate of the machining fluid, the temperature of the heating unit 10, and the temperature of the machining fluid under the condition that the heating unit 10 normally operates, thereby controlling the temperature of the machining fluid to be at the set temperature threshold.

Specifically, the control unit 40 may start the detection unit 20 before starting the heating unit 10, and confirm whether the working fluid temperature control device 100 can work normally according to the working fluid flow rate, the temperature of the heating unit 10, and the working fluid temperature.

For example, when the temperature of the heating unit 10 detected by the first temperature sensor 21 exceeds a set safety threshold, it indicates that the heating unit 10 is in an abnormal operating state. Therefore, the heating unit 10 needs to be inspected and repaired.

For example, when the control valve 17 is in the open state and the flow rate of the working fluid detected by the flow rate sensor 23 is 0, that is, no working fluid enters the heating unit 10, it may be that there is a problem in the line through which the working fluid flows into the heating unit 10 or that the flow rate sensor 23 cannot normally detect the working fluid. Thus, troubleshooting and maintenance of the piping and flow sensor 23 are required.

For another example, if the control unit 40 cannot normally receive the flow rate of the machining fluid, the temperature of the heating unit 10 and/or the temperature of the machining fluid detected by the detection unit 20, it may indicate that there is a connection line between the control unit 40 and the detection unit 20, or that there is an abnormality in the control unit 40 or the detection unit 20. Therefore, troubleshooting and maintenance of the connection lines, the control unit 40, and the detection unit 20 are required.

After confirming that the heating unit 10 can operate normally, the controller 42 may calculate the flow rate of the machining fluid according to the flow rate of the machining fluid flowing into the heating unit 10, and then calculate the flow rate of the machining fluid, the temperature of the heating unit 10, and the temperature of the machining fluid flowing out of the heating unit 10 as input data by using a PID algorithm within a set temperature threshold, and the controller 42 may control the heating unit 10 to operate at the calculated power.

Wherein, can understand, the control unit 40 can control the heater 15 to preheat the channel 12 first, makes the channel 12 reach predetermined temperature value, controls the governing valve 17 again and opens so that the processing fluid flows into the channel 12 after preheating, so can accelerate the heat treatment of processing fluid.

It will be appreciated that the temperature threshold to be reached by the working fluid may be set accordingly with respect to the working fluid so that the working fluid is at a suitable temperature value or temperature range, so as to fully perform the lubricating and cooling functions.

The control unit 40 may also confirm whether the working fluid temperature control device 100 can normally operate according to the working fluid flow rate, the temperature of the heating unit 10, and the working fluid temperature during the operation of the heating unit 10.

For example, when the temperature of the heating unit 10 exceeds a set safety threshold, which indicates that the heating unit 10 is overheated, the control unit 40 controls the heating unit 10 to stop operating in order to prevent the heating unit 10 from burning out.

For example, when the temperature of the working fluid exceeds the set temperature threshold, it indicates that the heating operation of the heating unit 10 is abnormal, and therefore, the control unit 40 controls the heating unit 10 to stop operating so as to reduce the influence of the excessive temperature on the quality and performance of the working fluid.

For another example, if the temperature of the working fluid and the temperature of the heating unit 10 do not change within a predetermined time, it may indicate that there is a connection line between the control unit 40 and the detection unit 20 or that there is an abnormality in the detection unit 20. Since the control unit 40 cannot obtain real detection data, the control unit 40 cannot effectively control the temperature of the machining liquid based on the detection data of the detection unit 20, and thus the control unit 40 controls the heating unit 10 to stop operating so as to troubleshoot a malfunction.

It will be appreciated that, since the heating unit 10 stops the heating operation, the control unit 40 further controls the regulating valve 17 to close to prevent the processing liquid from being transferred between the heating unit 10 and the processing liquid collecting port 200.

Referring to fig. 1 and 4, the temperature control apparatus 100 for machining fluid may further include an alarm unit 50. The alarm unit 50 is connected to the control unit 40. In this way, the alarm unit 50 can give an alarm when the machining fluid temperature control device 100 is abnormal under the control of the control unit 40.

It is understood that the present application does not limit the installation position of the alarm unit 50, and the alarm unit 50 may be disposed on the housing 41, the base plate 30, or the cover 18 of the control unit 40, for example.

It will be appreciated that the application is not limited to the type of alarm unit 50. For example, the alarm unit 50 may be an indicator lamp, and the indicator lamp may be turned on to prompt the operator when the process fluid temperature control device 100 is abnormal. As another example, the alarm unit 50 may be an audible and visual alarm, which may provide an audible and visual alarm when the machining fluid temperature control apparatus 100 is abnormal. It is understood that when a display screen is provided on the surface of the housing 41, the display screen may display the abnormality of the processing liquid temperature control device 100 in the form of characters or the like when the processing liquid temperature control device 100 is abnormal under the control of the control unit 40.

In some embodiments, the control unit 40 may also be connected to a terminal. The terminal can be a PLC industrial control computer, a mobile phone, a tablet computer and/or a computer and the like.

The control unit 40 may transmit the flow rate of the machining liquid, the temperature of the heating unit 10, the temperature of the machining liquid, the open/close state of the regulating valve 17, and the operation state of the liquid pump 201 to the terminal, so that the operator can very conveniently view the information on the terminal. The operator may also issue related control commands through the terminal, so that the control unit 40 may control the operation states of the heating unit 10 and the water pump, and the open and closed states of the regulating valve 17 based on the related control commands. The operator may also set safety and temperature thresholds via the terminal, which may send the safety and temperature thresholds to the controller 42. The control unit 40 may also transmit an alarm prompt signal to the terminal when the machining-fluid temperature control device 100 is abnormal.

The working principle of the processing liquid temperature control device 100 is as follows:

the controller 42 is first started, and the controller 42 controls the regulating valve 17 to open, and controls the liquid pump 201 to start working, so that the liquid pump 201 pumps the machining liquid at the machining liquid collecting end 200 to the liquid inlet interface 13 and flows into the channel 12 through the liquid inlet interface 13.

The controller 42 controls the detection unit 20 to perform a detection operation to confirm whether the machining fluid temperature control device 100 can operate normally based on detection data of the detection unit 20.

In the case where it is confirmed that the working fluid temperature control apparatus 100 can normally operate, the controller 42 controls the heating unit 10 to start operating to perform the preheating process on the tunnel 12.

In this process, since the detection unit 20 performs the detection operation all the time, the detected flow rate of the machining fluid flowing into the heating unit 10, the temperature of the heating unit 10, and the temperature of the machining fluid flowing out of the heating unit 10 can be transmitted to the controller 42 in real time.

After receiving the machining fluid flow rate, the temperature of the heating unit 10, and the machining fluid temperature detected in real time, the controller 42 determines whether the machining fluid temperature control device 100 is operating normally in real time based on the machining fluid flow rate, the temperature of the heating unit 10, and the machining fluid temperature.

When it is confirmed that the working fluid temperature control device 100 is operating normally, the controller 42 calculates the flow rate of the working fluid, the temperature of the heating unit 10, and the power to be achieved by the heating unit 10 corresponding to the temperature of the working fluid in real time using the PID algorithm, and controls the heating unit 10 in real time according to the calculated power. Therefore, the heating unit 10 can operate with the power calculated in real time to heat the processing fluid in the channel 12, so that the temperature of the processing fluid flowing out from the fluid outlet 14 is always kept at the set temperature threshold.

Thus, the machining fluid temperature control device 100 can supply the machining fluid required for machining for a long time, and since the temperature of the machining fluid is at the set temperature threshold, the temperature is suitable and the variation range is small, the machining fluid can stably exert the functions of lubrication and cooling, which is beneficial to ensuring the machining efficiency, the machining precision and the quality of the product.

It is understood that the controller 42 may also predict whether the temperature of the heating unit 10 exceeds the safety threshold and/or the temperature of the machining fluid exceeds the temperature threshold after the power is calculated, and recalculate the power that the heating unit 10 should reach if the temperature of the heating unit 10 exceeds the safety threshold and/or the temperature of the machining fluid exceeds the temperature threshold, so as to avoid the temperature of the heating unit 10 exceeding the safety threshold and/or the temperature of the machining fluid exceeding the temperature threshold as much as possible, and increase the safety factor of the machining fluid heating process.

When the controller 42 confirms that the working fluid temperature control device 100 is operating abnormally, it controls the alarm unit 50 to give an alarm and further controls the regulating valve 17 to close.

When the machining fluid temperature control device 100 has a connection terminal, the controller 42 also sends the machining fluid flow rate, the temperature of the heating unit 10, and the machining fluid temperature to the terminal in real time, and sends an alarm prompt signal to the terminal when the machining fluid temperature control device 100 is abnormally operated.
