[0002] In the cement production process, bucket elevator is a common equipment, and the chain plate is an important structure in the bucket elevator. In the cement production process, the bucket elevator is used for a long time, and the chain plate will also crack and crack due to fatigue, and finally break, which will lead to production suspension accidents.

[0003] Therefore, although the chain plate appears to break suddenly during the production process, the chain plate does not break all at once, but is a slower process. For example, there will be cracks at first, and then the cracks will slowly turn into cracks, and the cracks will break after a long time.

[0004] Therefore, in order to avoid the chain plate from breaking, you can find out when the chain plate has cracks or cracks, and replace the chain plate in advance to prevent the chain plate from breaking suddenly, and effectively prevent the production stoppage accident caused by the bucket elevator chain plate breaking.

[0005] Previously, studies have been conducted on the use of ultrasonic technology to detect defects in bucket elevator chain plates for cement production.

[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0043] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0044] The method for detecting defects in the bucket elevator chain plate of cement production provided in the embodiment of the present application can be applied to Figure 1In the application environment shown, the application environment includes chain plates, amorphous wire weak magnetic sensors and computer equipment.

[0045] The amorphous wire is installed near the chain plate, and further, is installed near the position where defects are likely to occur on the chain plate.

[0046] Among them, the computer device can be a host computer. Further, the host computer is connected to the amorphous wire weak magnetic sensor signal to receive the real-time magnetic field strength of the chain plate sent by the amorphous wire weak magnetic sensor, and compares the real-time magnetic field strength with the normal strength to determine whether the chain plate has defects.

[0047] Optionally, the application environment further includes a display terminal connected to the host computer for receiving and displaying data sent by the host computer. Further, the data sent by the host computer may be the real-time magnetic field strength, normal magnetic field strength and detection results of the chain plate.

[0048] In addition, the chain plates mentioned in this application, unless otherwise specified, are chain plates on the structure of a cement production bucket elevator.

[0049] In an exemplary embodiment, Figure 2 As shown, a method for detecting defects in a bucket elevator chain plate of a cement production is provided, the method being executed by a computer device. Figure 1 Taking the host computer in as an example, the following steps 201 to 204 are included:

[0050] Step 201, receiving the real-time magnetic field strength sent by the amorphous wire weak magnetic sensor at every predetermined time interval, wherein the amorphous wire weak magnetic sensor is installed near the chain plate of the cement production bucket elevator to be detected.

[0051] The predetermined time length may be an empirical value, for example, the predetermined time length may be 10 minutes.

[0052] Among them, the amorphous wire weak magnetic sensor is an ultra-small, highly sensitive weak magnetic sensor, which is used to collect the magnetic field strength of the chain plate in real time and send it to the host computer.

[0053] Furthermore, the amorphous wire weak magnetic sensor is installed at a first predetermined position, the first predetermined position is close to a second predetermined position, and the second predetermined position is a position where the probability of defects in the chain plate of the bucket elevator for cement production is greater than a predetermined value.

[0054] Furthermore, for the positions on the chain plate where defects may occur, the probability of the defects occurring is determined in advance, which can be determined manually based on experience.

[0055] The predetermined value is determined manually based on experience, for example, 0.3, and defects include cracks, fissures, fractures, etc. Positions where the probability of defects occurring is greater than the predetermined value can be considered as positions on the chain plate where defects are prone to occur.

[0056] Therefore, the amorphous wire weak magnetic sensor is installed at the second predetermined position to collect the magnetic field strength at the position on the chain plate where defects such as cracks, fissures, and fractures are likely to occur in real time.

[0057] Furthermore, the first predetermined position may be other positions on the cement production bucket elevator, for example, may be a panel.

[0058] Furthermore, locations on the chain plate where defects such as cracks, fissures, and breakages are prone to occur include the outside of the chain plate, the inside of the chain plate, the outer edge of the chain plate, the outer edge of the shaft sleeve, and the like.

[0059] Step 202, comparing the real-time magnetic field strength with a normal magnetic field strength, where the normal magnetic field strength is the magnetic field strength corresponding to when the bucket elevator chain plate of cement production has no defects.

[0060] The normal magnetic field strength is stored in the server in advance so that it can be obtained in time when needed.

[0061] This application is based in principle on Figure 3 and Figure 4 The principle of magnetic induction on the surface of the object shown, Figure 3 is the magnetic induction line corresponding to the object 100 without defects, Figure 4 In FIG. 1 , the position of the triangle is the defect of the object 100, and the magnetic induction lines of the object 100 when the defect exists are shown. The present application detects defects by using the difference in magnetic field strength generated by the magnetic induction lines of the object without defects and the magnetic induction lines of the object with defects.

[0062] Further, Figure 5 This is a schematic diagram of a bucket elevator driving chain plate in cement production with crack defects. Figure 5 The position indicated by the middle arrow is the crack defect of the chain plate.

[0063] For the internal composition of the amorphous wire weak magnetic sensor, please refer to Figure 6 The amorphous wire weak magnetic sensor includes a three-axis geomagnetic sensor, an analog adjustment circuit, an analog-to-digital converter (English full name: Analog-to-digital converter; English abbreviation: ADC) and a repairer (correction software). Furthermore, a communication interface is provided on the processor to transmit data with a host computer through the communication interface. For a more detailed structure of the amorphous wire weak magnetic sensor, please refer to the relevant prior art, and this application will not elaborate on this.

[0064] When used to detect defects, the sensor relies on the induction of the amorphous wire inside the sensor to the magnetic field of the surrounding objects. The surrounding weak magnetic signals are converted into electrical signals through its coil to identify changes in the magnetic field.

[0065] When the real-time magnetic field strength is consistent with the normal magnetic field strength, step 203 is executed; when the real-time magnetic field strength is inconsistent with the normal magnetic field strength, step 204 is executed.

[0066] Step 203: When the real-time magnetic field strength is consistent with the normal magnetic field strength, it is determined that the detection result is defect-free.

[0067] The fact that the real-time magnetic field strength is consistent with the normal magnetic field strength can be understood as: the real-time magnetic field strength varies within a predetermined range around the normal magnetic field strength.

[0068] Furthermore, in actual operation, the magnetic field strength can be converted into voltage or current, and the real-time magnetic field strength can be compared with the normal magnetic field strength by comparing the voltage or current. In this case, the predetermined range is also voltage or current. Furthermore, the predetermined range can be an empirical value, for example, 5V for voltage and 10 mA for current.

[0069] Step 204: When the real-time magnetic field strength is inconsistent with the normal magnetic field strength, determine that the detection result is defective.

[0070] Similarly, the inconsistency between the real-time magnetic field strength and the normal magnetic field strength can be understood as: the variation range of the real-time magnetic field strength exceeds the predetermined range around the normal magnetic field strength.

[0071] Generally, when defects are present, the magnetic field strength increases.

[0072] The method for detecting defects in the bucket elevator chain plate of cement production provided in the embodiment of the present application uses an amorphous wire weak magnetic sensor to obtain the real-time magnetic field strength of the bucket elevator chain plate of cement production in real time; then compares the real-time magnetic field strength with the normal magnetic field strength to determine whether the real-time magnetic field strength is consistent with the normal magnetic field strength; if they are consistent, it is determined that the bucket elevator chain plate of cement production has no defects; if they are inconsistent, it is determined that the bucket elevator chain plate of cement production has defects; thereby achieving the purpose of real-time detection of defects in the bucket elevator chain plate of cement production. Therefore, compared with the prior art that uses ultrasonic waves for defect detection, the present application uses real-time magnetic field strength for defect detection. Since a more accurate real-time magnetic field strength of the chain plate can be obtained, the present application improves the accuracy of detecting defects in the bucket elevator chain plate of cement production.

[0073] In addition, the prior art requires the application of liquid coupling agent in advance when using ultrasonic echo reflection for detection. However, the present application does not require the application of liquid coupling agent in advance, thus simplifying the detection process and improving the convenience of the detection process.

[0074] In addition, the above method can timely detect whether there are defects in the chain plate, and when defects are detected, timely measures can be taken to reduce the sudden breakage of the chain plate during the cement production process, thereby reducing the production stoppage due to chain plate breakage, and further improving cement production efficiency.

[0075] Optionally, when comparing the magnetic field strength, it can be done with the aid of two-dimensional coordinates, where the abscissa of the two-dimensional coordinates is the time period or the displacement period of the chain plate compared to the reference position, and the ordinate is the magnetic field strength.

[0076] The time period can be understood as the time it takes for the chain plate to run for one cycle, starting from a fixed point on the chain plate. Figure 7 and Figure 8 For example, the chain plate runs for a period of 40 minutes.

[0077] The displacement cycle can be understood as: taking a fixed point on the chain plate as the starting point, the distance between the fixed point and the reference position when the chain plate runs one circle.

[0078] in, Figure 7 A coordinate diagram of real-time magnetic induction intensity collected for an amorphous wire weak magnetic sensor. Figure 8 This is a coordinate diagram of normal magnetic field intensity.

[0079] Alternatively, see Fig. 9 In another exemplary embodiment of the present application, the above normal magnetic field strength is obtained by following steps 301 to 303:

[0080] Step 301, receiving a plurality of first magnetic field intensities, wherein the first magnetic field intensities are obtained by collecting data from a same cement production bucket elevator chain plate without defects using a plurality of amorphous wire weak magnetic sensors.

[0081] Since the first magnetic field strength is acquired by multiple amorphous wire weak magnetic sensors on the same chain plate, multiple first magnetic field strengths are acquired.

[0082] Step 302, receiving a plurality of second magnetic field intensities, wherein the plurality of second magnetic field intensities are obtained by collecting the magnetic field intensities of a plurality of cement production bucket elevator chain plates without defects by using the same amorphous wire weak magnetic sensor.

[0083] Since the second magnetic field strength is acquired by an amorphous wire weak magnetic sensor on a plurality of chain plates, the acquired second magnetic field strength is also multiple.

[0084] Step 303: Calculate an average value of the multiple first magnetic field strengths and the multiple second magnetic field strengths to obtain the normal magnetic field strength.

[0085] Through the above steps 301 to 303, the accuracy of the normal magnetic field strength can be improved, thereby improving the accuracy of chain plate detection.

[0086] Optionally, in another exemplary embodiment of the present application, after step 203 or step 204, the method further includes the following steps 401 to 403:

[0087] Step 401: Send the real-time magnetic field strength to a display terminal so that the real-time magnetic field strength is displayed through the display terminal.

[0088] Step 402: Send the normal magnetic field strength to the display terminal so that the normal magnetic field strength is displayed through the display terminal.

[0089] Step 403: Send the detection result to the display terminal so that the detection result is displayed through the display terminal.

[0090] The real-time magnetic field strength, normal magnetic field strength and detection results are displayed on the display terminal, so that the staff can understand the detection situation in time.

[0091] Optionally, in another exemplary embodiment of the present application, a device for detecting defects in the chain plate of a cement production bucket elevator is provided, the device comprising: a cement production bucket elevator chain plate body and an amorphous wire weak magnetic sensor, the amorphous wire weak magnetic sensor is installed at a first predetermined position, the first predetermined position is close to a second predetermined position, and the second predetermined position is a position where the probability of defects in the cement production bucket elevator chain plate body is greater than a predetermined value.

[0092] For descriptions of the first predetermined position, the second predetermined position and the predetermined value, please refer to the relevant description in the method embodiment.

[0093] The device for detecting defects in the chain plate of a bucket elevator for cement production provided in the embodiment of the present application obtains the real-time magnetic field strength of the chain plate of the bucket elevator for cement production in real time by installing an amorphous wire weak magnetic sensor near the position where the chain plate is prone to defects; thus, it can be determined whether the chain plate has defects based on the real-time magnetic field strength, thereby achieving the purpose of real-time detection of defects in the chain plate of the bucket elevator for cement production. Therefore, compared with the prior art that uses ultrasonic waves for defect detection, the present application uses an amorphous wire weak magnetic sensor for defect detection, which does not require the application of liquid coupling agent in advance, simplifies the detection process, and improves the convenience of the detection process.

[0094] In addition, the eddy current strong magnetic defect detection in the prior art requires an external magnetic field to be applied to the defect detection object, but there is no suitable position to apply an external magnetic field to the bucket elevator chain plate of cement production, so this method is not suitable for detecting defects in the bucket elevator chain plate of cement production. The amorphous wire weak magnetic sensor used in this application is not only small in size and can be installed in a small space near the chain plate to achieve miniaturization of the equipment, but also does not require an external magnetic field, simplifying the detection process.

[0097] Optionally, in another exemplary embodiment of the present application, the apparatus further includes a computer device. Further, the computer device may be a host computer, and the host computer is connected to the amorphous wire weak magnetic sensor signal.

[0098] The amorphous wire weak magnetic sensor sends the collected real-time magnetic field strength to the host computer; after receiving the real-time magnetic field strength, the host computer compares the real-time magnetic field strength with the normal magnetic field strength to determine whether there is a defect in the chain plate. The specific determination process can be found in the relevant description in the above method embodiment, and this application will not describe it in detail here.

[0099] Optionally, in another exemplary embodiment of the present application, the device further includes a display terminal, and the display terminal is signal-connected to the host computer.

[0100] The display terminal is used to receive signals sent by the host computer, where the signals include real-time magnetic field strength, normal magnetic field strength and detection results, so that the real-time magnetic field strength, normal magnetic field strength and detection results can be displayed through the display terminal, so that the staff can understand the detection situation in time.
