[0048] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0049] The liner monitoring system and the mixer of the present invention will be described below with reference to the accompanying drawings.

[0050] like Figure 1 and Figure 2 As shown, the present invention provides a lining monitoring system, wherein the lining monitoring system comprises:

[0051] A lining device 1, wherein the inner side of the lining device 1 is set as a working surface 11, and the lining device 1 is formed with an installation space 12 on a side away from the working surface 11;

[0052] The thickness monitoring device 2 is arranged in the installation space 12 and is used to detect the thickness from the thickness monitoring device 2 to the working surface 11;

[0053] The control device is communicatively connected with the thickness monitoring device 2 and is configured as follows:

[0054] The service life of the lining plate device 1 is determined based on the detection data of the thickness monitoring device 2 .

[0055] When the above-mentioned lining monitoring system is used, the inner side of the lining device 1 is set as a working surface 11, and the working surface 11 is used to contact the raw material to be processed. The lining device 1 is formed with an installation space 12 on the side away from the working surface 11. The thickness monitoring device 2 is arranged in the installation space 12 and is used to detect the thickness from the thickness monitoring device 2 to the working surface 11. The control device is communicated with the thickness monitoring device 2 and determines the service life of the lining device 1 according to the detection data of the thickness monitoring device 2. Then, through the lining monitoring system, the wear condition of the lining device 1 can be automatically obtained. Compared with manual judgment, the result is more accurate, and the control device can output the service life of the lining device 1 according to the wear condition, so as to help the operator to more intuitively determine the timing of replacing the lining device 1. On the premise of ensuring that the lining device 1 is not damaged, the replacement frequency of the lining device 1 is reduced to reduce the production cost.

[0056] It should be noted that the lining monitoring system provided by the present invention is applicable to a variety of processing equipment, and is particularly applicable to a concrete mixing mixer. The following embodiments are explained using a concrete mixing mixer as an example, and the raw materials to be processed are aggregates commonly used in construction.

[0057] like Figure 5 As shown, in the embodiment of the present invention, determining the service life of the lining device 1 according to the detection data of the thickness monitoring device 2 includes:

[0058] Step S100 , determining the single wear amount of the working surface 11 .

[0059] It can be understood that the single wear amount refers to the mass or thickness of the wear of the working surface 11 of the liner device 1 after the mixer completes one raw material processing (the two can be converted according to the area of ​​the working surface 11 and the material density of the hardened plate 134 of the liner device 1). The purpose of determining the single wear amount is to quantify the wear of the raw material to be processed on the working surface 11, so as to assist in judging the wear trend of the working surface 11 in the processing of subsequent batches.

[0060] Specifically, the single wear amount can be obtained through preliminary experimental measurements, or a mapping formula from material parameters of component processing raw materials and processing time to wear amount can be obtained based on the preliminary experiments.

[0061] Step S200 , determining the remaining wear amount according to the preset safety thickness and the detection data of the thickness monitoring device 2 .

[0062] Specifically, when the wear amount is set to the thickness of the wear on the working surface 11, the remaining wear amount is: the real-time thickness measured by the thickness monitoring device 2 - the preset safety thickness; when the wear amount is set to the mass of the wear on the working surface 11, the remaining wear amount is expressed as: (real-time thickness - preset safety thickness) × the area of ​​the working surface 11 × the material density of the lining device 1 at the working surface 11.

[0063] Step S300, determining the service life of the lining device 1 according to the remaining wear amount and the single wear amount.

[0064] Through this method, the service life of the lining device 1 can be quantified, so that the operator can intuitively know the wear of the lining device 1. It is understandable that the material parameters of the principle to be processed and the processing time will affect the single wear amount of the lining device 1. If the thickness of the lining device 1 is used as the judgment standard for whether it needs to be replaced, it is still difficult for the operator to determine whether the thickness of the lining device 1 can meet the needs of the next processing operation.

[0065] like Figure 6 As shown, in the embodiment of the present invention, step S100, determining the single wear amount of the working surface 11 includes:

[0066] Step S110, obtaining material parameters and processing time of the raw material to be processed.

[0067] Specifically, the material parameters and processing time can be manually input into the control device by the operator, or a material mixing and processing table can be configured in the control device. In the table, the type of concrete corresponds to the material parameters and processing time one by one. The operator selects the required concrete type on the control panel of the control device, and the control device can automatically determine the material parameters and processing time.

[0068] Step S120, inputting material parameters and processing time into a life monitoring model to obtain a single wear amount.

[0069] Specifically, the material parameters include material strength and material wear coefficient, and the life monitoring model can be in the form of a calculation formula or a table. If the calculation formula is used, the life monitoring model is specifically:

[0070]

[0071] In the formula, H m represents the hardness of the working surface 11; M represents the single wear amount of the working surface 11 (referring to the mass of the wear of the working surface 11); K represents the probability of forming wear chips; K xrepresents the material wear coefficient; C represents the material strength; T represents the processing time.

[0072] If a table is used, a mapping table of component material parameters, processing time and single wear amount is prepared through multiple preliminary experiments or combined with production parameters. The mapping table is stored in a storage module of the control device, and the control device searches for corresponding results in the table through the input parameters.

[0073] Through the life monitoring model, the control device can quickly determine the remaining service life of the lining device 1 and promptly remind the operator to replace the lining device 1.

[0074] Specifically, the control device is also equipped with an alarm module, which is used to send a reminder signal to the operator when the service life of the lining device 1 reaches a preset value, so as to remind the operator to replace the lining device 1 in time. Figure 7 As shown, after the alarm module is configured, the execution process of the control device is as follows:

[0075] The thickness monitoring device 2 first measures the real-time thickness of the lining device 1 and sends the real-time thickness data to the control device. The control device inputs the aggregate hardness, formula strength and single-tank mixing time into the life monitoring model to obtain the single wear amount of the lining device 1. The service life of the lining device 1 is determined by the single wear amount and real-time thickness of the lining device 1. When the service life reaches the alarm threshold, the alarm module is activated. When the service life is greater than the alarm threshold, the thickness monitoring device 2 continues to monitor the thickness of the lining device 1.

[0076] Further, see Figure 8 , the alarm program of the alarm module is set as follows:

[0077] The alarm program starts. When the service life of the lining device 1 reaches the alarm threshold, the alarm module sends out the first reminder maintenance signal. If the operator does not replace the lining device 1, the alarm module continues to send out the first reminder maintenance signal. If the operator completes the first replacement of the lining device 1, the alarm module continues to execute the subsequent process; eight hours after the operator completes the first replacement of the lining device 1, the alarm module sends out the second reminder maintenance signal. If the operator does not replace the lining device 1, the alarm module continues to send out the second reminder maintenance signal. If the operator completes the second replacement of the lining device 1, the alarm module continues to execute the subsequent process; twenty-four hours after the operator completes the second replacement of the lining device 1, the alarm module sends out the third reminder maintenance signal. If the operator does not replace the lining device 1, the alarm module continues to send out the third reminder maintenance signal. If the operator completes the third replacement of the lining device 1, the alarm module continues to execute the subsequent process; when the operator completes the third replacement of the lining device 1, the alarm module sends out a reminder maintenance signal every one hundred hours, and the reminder maintenance signal continues until the operator replaces the lining device 1.

[0078] It should be noted that the detection of whether the lining device 1 is replaced can be done manually by the operator, or a corresponding detection device can be set up. For example, an electrical component that can send an electrical signal is installed on the lining device 1, and the electrical component is electrically connected to the control device. When the lining device 1 is removed, the electrical component is disconnected from the control device. When the lining device is replaced, the new electrical component is electrically connected to the control device, and the control device can accordingly judge that the lining device 1 has been replaced.

[0079] Furthermore, the alarm module may send out a maintenance reminder signal by connecting to a signal light or an audio device. For a blender with a display screen, the alarm module may also display the maintenance reminder information on the display screen.

[0080] Furthermore, the service life of the lining device 1 may refer to the thickness of the lining device 1, or the usage time, or the remaining number of operations. Figure 8In a specific embodiment of the present invention, the alarm threshold is set to the thickness of the lining device 1 being less than or equal to 0.6(m+n), wherein (m+n) represents the initial thickness of the lining device 1. Of course, the alarm threshold can also be set to other conditions, for example, whether the use time of the mixer is greater than five hours. If it is greater than five hours, the alarm module sends the first reminder maintenance signal; or the alarm threshold is set to the remaining number of working times of the lining device 1 being less than one. Through the above-mentioned life monitoring model, the single wear amount of the lining device 1 can be calculated, and combined with the thickness data measured by the thickness monitoring device and the preset safety thickness, the remaining wear amount of the lining device 1 can be obtained. The remaining number of uses of the lining device 1 can be determined by the remaining wear amount and the single wear amount. When the control device determines that the remaining number of working times of the lining device 1 is less than one, the alarm module sends the first reminder maintenance signal.

[0081] It is understandable that the above-mentioned service lives are all theoretical service lives. During the actual mixing process, the accuracy of the thickness monitoring device 2, the differences in raw materials from different batches, and the use environment may cause the actual service life of the lining device 1 to be unequal to the theoretical service life. In order to avoid the problem that the theoretical service life is greater than the actual service life, which leads to incorrect judgment on the replacement timing of the lining device 1, the control device can be set to multiply the determined theoretical service life by a safety factor to ensure that the theoretical service life will not exceed the actual service life. The setting of the safety factor is a commonly used technical means in the field of industrial design, so it will not be repeated here.

[0082] like Figure 1 As shown, in the embodiment of the present invention, the lining device 1 includes a lining body 13 and an adhesive filling layer 14. The inner side of the lining body 13 forms a working surface 11. The lining body 13 is formed with a filling hole through the thickness direction. The filling hole is sequentially set as a filling space and an installation space 12 from the inside to the outside. The adhesive filling layer 14 is placed in the filling space and flush with the working surface 11. When installing the lining monitoring system, the thickness monitoring device 2 is first embedded in the filling hole, and then the adhesive for forming the adhesive filling layer 14 is poured into the filling hole. Through this installation method, it can be ensured that the adhesive filling layer 14 covers the thickness monitoring device 2, and it is ensured that there is no gap between the thickness monitoring device 2 and the adhesive filling layer 14, thereby ensuring the accuracy of the detection.

[0083] It is understandable that the commonly used thickness detection methods are electromagnetic induction, ultrasonic propagation and beta-ray transmission. First, the electromagnetic induction principle determines the thickness through the eddy current signal generated by the induction coil on the surface of the object to be measured. The current size is related to the magnetic flux line strength, frequency and material conductivity. Secondly, the ultrasonic propagation principle uses the reflection time of ultrasonic waves inside the object to measure the thickness. Ultrasonic waves are generated and detected by crystals, and the regression time determines the thickness of the object. Finally, the beta-ray transmission principle calculates the thickness by measuring the signal intensity after the beta rays pass through the object. Its penetration is related to the mass of the object, the path length and the energy loss. All three methods can effectively measure the thickness of the object, but all require that the sensor be in effective contact with the object to be measured to avoid the presence of other media (such as air) between the sensor and the object to be measured affecting the detection results.

[0084] Specifically, the thickness monitoring device 2 actually detects the thickness of the adhesive filling layer 14. Compared with the lining body 13, the contact area between the adhesive filling layer 14 and the raw material is smaller. When the mixer is working, the raw material mainly contacts the lining body 13 on both sides of the adhesive filling layer 14. The wear degree of the adhesive filling layer 14 will not exceed the wear degree of the lining body 13 due to the material difference between the adhesive filling layer 14 and the lining body 13. The wear thickness of the adhesive filling layer 14 and the lining body 13 is roughly the same, and the real-time thickness of the adhesive filling layer 14 can be regarded as the real-time thickness of the lining body 13.

[0085] like Figure 1 As shown, in the embodiment of the present invention, the liner body 13 includes a bottom plate 131, a hardened layer 132 and a fastener 133. The hardened layer 132 is arranged on the inner side of the bottom plate 131, and the filling hole passes through the hardened layer 132 and the bottom plate 131 from the inside to the outside. The side of the hardened layer 132 facing away from the bottom plate 131 is set as the working surface 11. The fastener 133 is arranged on the outer side of the bottom plate 131 and is used to connect the inner wall of the mixer. Then the liner device 1 can be detachably installed to facilitate the replacement of the operator, and the liner body 13 adopts the structure of the bottom plate 131 + hardened layer 132. The replaced liner device 1 can re-lay the hardened layer 132 to achieve the reuse of other components of the liner device 1 and reduce the maintenance cost of the mixer.

[0086] Specifically, the lining body 13 also includes a frame 135 and reinforcing ribs 136. The frame 135 is arranged along the periphery of the bottom plate 131. The hardened layer 132 is located in the area enclosed by the frame 135, which protects the hardened layer 132. The reinforcing ribs 136 are used to connect the opposite sides of the frame 135 to support the bottom curvature and ensure that the installation curvature is qualified.

[0087] like Figure 2As shown, in the embodiment of the present invention, the thickness monitoring device 2 includes a thickness sensor 21, and the detection end of the thickness sensor 21 has at least two probes, and the at least two probes are arranged in sequence along the extension direction of the working surface 11, and have different probe lengths. Each probe can obtain a result corresponding to the detection, and at least two detection results can be obtained at different positions of the working surface 11 through at least two probes. By summarizing all the detection results, the accurate wear condition of the working surface 11 can be obtained, and the detection error can be reduced.

[0088] It should be noted that the thickness monitoring device 2 provided by the present invention is suitable for measuring the thickness of different types of lining devices 1, and is particularly suitable for measuring the thickness of arc-shaped lining devices 1. It is understandable that in the mixer, the raw materials to be processed will collide with the lining device 1 on the side wall of the mixer as the stirring paddle rotates, which is likely to cause greater wear at a local position of the working surface 11. By summarizing the detection results of at least two probes, misjudgment can be avoided.

[0089] Further, see Figure 3 The thickness monitoring device 2 also includes a data processor 22, a gateway and a computer 3 as a control device. The probe measures the thickness of the lining device 1 in real time, and the probe signal is connected to the data processor 22. The data processor 22 can convert the signal of each connected probe into digital form separately, and has the function of detecting whether the signal is disconnected in real time; the data processor 22 uses the CAN bus to transmit data to the gateway, and the gateway is connected to the computer 3 for communication. The service life of the lining device 1 can be determined through the life monitoring model, and whether each probe has an abnormal contact failure. The computer 3 is equipped with a display to realize data visualization. When the thickness of the lining device 1 is reduced to the life threshold, the alarm reminder program is started to realize the life monitoring and reminder functions.

[0090] Furthermore, the control device is also configured with a data iteration module, which updates the parameters of the life monitoring model based on the life monitoring model and in combination with the actual wear of the lining device 1 in the actual production process, thereby improving the accuracy of the life monitoring model.

[0091] like Figure 4As shown, in the embodiment of the present invention, the detection end of the thickness sensor 21 has a first probe 211, a second probe 212 and a third probe 213, and the first probe 211, the second probe 212 and the third probe 213 are arranged in sequence along the extension direction of the working surface 11, and the spacing between the first probe 211 and the working surface 11 is 0.3 (m + n), the spacing between the second probe 212 and the working surface 11 is 0.6 (m + n), and the spacing between the third probe 213 and the working surface 11 is 0.7 (m + n), wherein m represents the initial thickness of the hardened layer 132, and n represents the thickness of the bottom plate 131. The probes of the thickness sensor 21 are arranged in a stepped manner, which has wide adaptability. The stepped probes can measure irregular shapes such as arcs, and are suitable for the lining device 1 whose working surface 11 is an arc surface and a plane. The stepped arrangement can avoid stress concentration, enhance structural stability, and thus improve the service life of the thickness sensor 21. In addition, by setting the distance between each probe and the working surface 11, it can be better linked with the alarm module. For example, the distance between the second probe 212 and the working surface 11 is 0.6 (m+n). When the lining device 1 is worn to a thickness less than 0.6 (m+n), the second probe 212 will be damaged, and the data processor 22 loses the thickness data fed back by the second probe 212. The control device can determine that the real-time thickness of the lining device 1 is less than 0.6 (m+n). Even if the thickness sensor 21 has a detection error, it can remind the operator to replace the lining device 1.

[0092] It should be particularly noted that the above-mentioned distance between the probe and the working surface 11 refers only to the distance between the two in the initial state, that is, the distance between the probe and the working surface 11 when the hardened layer 132 is not worn.

[0093] Furthermore, the probe material is preferably stainless steel; a protective shell is provided on the top of each probe to reduce the impact of abnormal fracture of the hardened layer 132 on the sensor.

[0094] In an embodiment of the present invention, there are two filling holes, which are arranged on both sides of the fastener 133 along the extension direction of the working surface 11. There are two thickness monitoring devices 2, which are arranged one by one in the installation space 12 of the two filling holes.

[0095] In the embodiment of the present invention, the bottom plate 131 is configured as a metal part, and the hardening layer 132 is configured as a ceramic part.

[0096] Specifically, the hardened layer 132 can be set to one or a combination of 94 alumina ceramics, 96 alumina ceramics, 99 alumina ceramics, zirconium oxide ceramics, and silicon carbide ceramics. The bottom plate 131 can be set to one or a combination of Q355 and NM series wear-resistant steels. The material of the reinforcing rib 136 can be one or a combination of NM wear-resistant steel series, Bainite wear-resistant steel series, and cemented carbide.

[0097] In summary, the lining monitoring system provided by the present invention has the following beneficial effects:

[0098] (1) The present invention uses data acquisition technology to process the liner thickness to detect the amount of liner wear and determine whether it needs to be replaced. Compared with manual experience judgment, it is more intuitive and reliable.

[0099] (2) The data conversion device converts data signals according to the thickness detection results and automatically sends them to the upper control device, with a high degree of automation;

[0100] (3) The lining device 1 of the present invention can effectively improve the hardness of the wearing parts and accurately detect the service life of the wearing parts, thereby achieving the purpose of increasing the service life of the mixer equipment and accurately replacing the wearing parts, while not affecting the production capacity of the mixer.

[0101] Specifically, see Fig.10 and Fig.11 The shape of the lining device 1 can be a rectangle or a parallelogram; if the shape of the lining device 1 is set to be a rectangle, the reinforcing rib 136 divides the enclosed area of ​​the frame 135 into two equal rectangular areas; if the shape of the lining device 1 is set to be a parallelogram, the reinforcing rib 136 divides the enclosed area of ​​the frame 135 into two equal right-angled trapezoidal areas.

[0102] like Fig. 9 As shown, in order to achieve the above object, the present invention also provides a mixer, wherein the mixer includes the above liner monitoring system.
