Description

TECHNICAL FIELD

[0002] Cold ramming paste is a material used for the construction of aluminum electrolysis cells, which may include asphalt, polymers, fillers and other additives, which can maintain a certain fluidity and plasticity at low temperatures, facilitating construction and forming. Under-ramming of cold ramming paste refers to insufficient compaction of cold ramming paste during construction, which can lead to electrolyte leakage, affecting the efficiency and safety of the electrolysis cell. Over-ramming of cold ramming paste refers to excessive compaction of cold ramming paste, which can weaken the paste's ability to absorb thermal expansion stress during the start-up of the electrolysis cell, potentially causing the cathode bottom block to delaminate or leak, affecting the structural integrity and service life of the electrolysis cell. Penetration depth is an indicator used to measure the hardness or consistency of a material. Detecting the penetration depth of cold ramming paste can determine its consistency and bonding performance, ensuring that the cold ramming paste has appropriate fluidity and adhesion during construction, thereby ensuring the quality of the aluminum electrolysis cell and avoiding damage to the aluminum electrolysis cell due to poor performance of the cold ramming paste. Therefore, it is necessary to detect the penetration depth of cold ramming paste.

[0003] In the prior art, a penetration depth detection device measures the penetration depth of cold ramming paste by using a detection needle. The detection needle typically includes a vertically movable needle shaft, on which a standard mass needle or cone is mounted.

[0056] In order to clearly describe the technical solutions of the embodiments of the present application, the following briefly introduces some terms and technologies involved in the embodiments of the present application:

[0057] Penetration detection device: a device for measuring the hardness or consistency of a material. By vertically inserting a detection needle into the material under certain conditions, and measuring the depth of the detection needle, the device can determine the softness or hardness of the material to ensure that it meets certain engineering standards and quality requirements.

[0058] Detection needle: an elongated probe used to insert into the material being measured. Its main function is to measure the insertion depth of the material by applying a certain pressure or weight. The insertion depth of the detection needle can reflect the softness or consistency of the material.

[0059] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description of the exemplary embodiments is intended to apply to all alternative modifications and embodiments as would be apparent to those skilled in the art. It is to be understood that the following description is not meant to limit the application in any way.

[0060] The technical solutions of the present application will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes may not be described again in some examples. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0061] In order to clearly understand the technical solutions of the present application, the prior art solutions will be described in detail. In the use process of cold ramming paste, the cold ramming paste may have problems such as insufficient flowability, uneven hardening or poor adhesion, which will affect its performance in sealing, filling or bonding applications. By detecting the penetration of cold ramming paste, the consistency and hardness of cold ramming paste can be accurately judged, so as to ensure its applicability in different environmental conditions, to avoid the problems of flowability and hardening in the use process, and to ensure the reliability and effectiveness of the product.

[0062] At present, in the detection process of the penetration detection device, the cold ramming paste sample is usually placed in a standard container, and then the detection needle of the penetration detection device is vertically penetrated into the cold ramming paste under certain time and load. The consistency and hardness of the cold ramming paste are determined by measuring the penetration depth of the needle. However, the penetration detection device relies on mechanical measurement of depth and lacks temperature monitoring, which may lead to inconsistency of measurement results under different temperature conditions; and the traditional penetration detection device lacks automatic data processing capability, and still needs manual detection of the depth of the penetration hole after obtaining the penetration hole, which increases the error of manual detection. Therefore, the current penetration detection device has the problems of lack of temperature regulation and large manual detection error.

[0063] Therefore, in order to solve the problems of lack of temperature regulation and large manual detection error in the penetration detection device in the prior art, it is found in the research that in order to solve the problem, a penetration detection device is needed, which can calculate the penetration according to the depth and temperature of the penetration hole, and does not need manual detection: ① multiple sensors can be used to detect multiple parameters required for calculating the penetration. ② In order to detect the depth of the penetration hole, a sensor for detecting the depth can be arranged on the device. ③ In order to detect the temperature of the penetration hole, a sensor for detecting the temperature can be arranged on the device. After obtaining the depth and temperature of the penetration hole, the penetration is calculated according to the depth and temperature.

[0064] Specifically:

[0065] A sensor for measuring distance can be arranged on the device connected with the detection needle, and the depth of the needle entry hole is detected by the sensor for measuring distance after the detection needle is inserted into the cold rammer paste to obtain the needle entry hole. Then, a sensor for measuring temperature is arranged on the detection needle, and the temperature of the needle entry hole is detected by the sensor for measuring temperature after the detection needle is inserted into the cold rammer paste. Finally, the needle entry degree is calculated according to the depth and the temperature.

[0066] The needle entry degree detection device of the embodiment of the present application is arranged with a first sensor and a second sensor on the bottom plate connected with the detection needle, the first sensor is used for measuring the depth of the needle entry hole, and the second sensor is used for detecting the temperature of the needle entry hole. The bottom plate is also provided with a calculator, and the calculator calculates the needle entry degree according to the depth and the temperature of the needle entry hole. The temperature is an important factor affecting the physical properties of the material, and the viscosity and hardness of the cold rammer paste may change with the change of the temperature, so it is possible that the actual needle entry degree of the material cannot be comprehensively reflected only by relying on the depth. By detecting the depth and the temperature of the needle entry hole and calculating the needle entry degree based on the two parameters, compared with calculating the needle entry degree only according to the depth, the accuracy and the reliability of the measurement can be significantly improved. By introducing the temperature parameter, the change of the material properties caused by the change of the temperature can be compensated, so that the calculation result of the needle entry degree is more representative and consistent.

[0067] Based on the above creative finding, the technical scheme of the present application is proposed.

[0068] The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0069] Figure 1 The structure of the needle entry degree detection device provided by the embodiment of the present application is shown in Figure 1 . As shown in Figure 1 , in the present embodiment, the needle entry degree detection device comprises a connecting rod 100, a hammer body 200, a bottom plate 300 and a detection needle 400.

[0070] Specifically, the connecting rod 100 is used to provide a stable sliding path in the device, enabling the hammer body 200 to move along its free fall, ensuring the precise movement of the hammer body 200 and the base plate 300 in the vertical direction. The hammer body 200 is used to provide impact force during the detection process. It slides along the connecting rod 100 in a free-fall manner, thereby pushing the base plate 300 to move downward, causing the detection needle 400 to insert into the cold rammer paste. The function of the hammer body 200 is to ensure that the detection needle 400 can be inserted into the material with constant force and speed. The base plate 300 is used to support and transmit the impact force of the hammer body 200 to the detection needle 400. The design of the base plate 300 ensures that the detection needle 400 can be inserted vertically into the cold rammer paste. The detection needle 400 is used to actually insert into the cold rammer paste to form a needle hole. One end of it is connected to the base plate 300, and the other end is provided with a second sensor 4001 for measuring the temperature of the needle hole. The main function of the detection needle 400 is to provide physical measurement data by inserting into the cold rammer paste, which is then used to calculate the penetration degree of the cold rammer paste.

[0071] The hammer body 200 is provided with a first moving groove, and the connecting rod 100 is in sliding connection with the first moving groove. The first moving groove is used to provide a stable sliding track for the hammer body 200.

[0072] Specifically, a slot with the same size as the connecting rod 100 can be designed on the hammer body 200 as the first moving groove, which can tightly fit with the connecting rod 100. The size and shape of the first moving groove match the connecting rod 100, enabling the hammer body 200 to slide smoothly along the connecting rod 100. This design can provide a stable sliding track for the hammer body 200, ensuring that the hammer body 200 remains on the correct path during free fall, thereby accurately transmitting force to the base plate 300. This stable sliding mechanism ensures the repeatability and accuracy of the penetration detection process.

[0073] The top of the base plate 300 is provided with a second moving groove 3001, and the connecting rod 100 is in sliding connection with the second moving groove 3001. The bottom of the base plate 300 is connected to one end of the detection needle 400.

[0074] Specifically, a slot with the same size as the connecting rod 100 can be designed on the top of the base plate 300 as the second moving groove 3001. The size and shape of the second moving groove 3001 match the connecting rod 100, enabling the base plate 300 to slide smoothly along the connecting rod 100. This design can ensure that the base plate 300 can stably move downward along the connecting rod 100 under the action of the force exerted by the hammer body 200, thereby causing the detection needle 400 to be inserted vertically into the cold rammer paste. The base plate 300 is connected to one end of the detection needle 400, ensuring that the detection needle 400 can accurately insert into the cold rammer paste when the base plate 300 moves, so as to measure the penetration degree. This sliding connection mechanism ensures the accuracy and stability of the detection process.

[0075] The bottom of the base plate 300 is provided with a first sensor 3002 for detecting the depth of the needle penetration hole.

[0076] Specifically, when the detection needle 400 is inserted into the cold rammer paste under the action of the hammer body 200, the first sensor 3002 senses and records the depth data of the needle penetration hole. This depth measurement is crucial for calculating the penetration degree of the cold rammer paste, because the penetration degree is determined according to the depth of the detection needle insertion. By obtaining accurate depth data, the first sensor 3002 provides the necessary basis for subsequent calculation and analysis.

[0077] The other end of the detection needle 400 is provided with a second sensor 4001 for detecting the temperature of the needle penetration hole.

[0078] Specifically, the second sensor 4001 can directly measure the temperature when the detection needle 400 is inserted into the cold rammer paste. This temperature measurement is crucial for determining the physical properties of the cold rammer paste, because temperature can affect the penetration characteristics of the material. By obtaining the temperature data of the needle penetration hole, the second sensor 4001 provides the necessary information for the calculator 3003 to calculate the penetration degree of the cold rammer paste more accurately in combination with the depth data. This temperature measurement helps to improve the accuracy and reliability of the detection results.

[0079] The side of the base plate 300 is provided with a calculator 3003 for calculating the penetration degree of the cold rammer paste according to the depth and temperature.

[0080] Specifically, the calculator 3003 receives the depth data from the first sensor 3002 and the temperature data from the second sensor 4001, and processes and analyzes these data through a pre-set algorithm or formula to calculate the penetration degree of the cold rammer paste. The role of the calculator 3003 is to convert the physical measurement data into a useful penetration value, which reflects the physical properties of the material under certain conditions. By integrating depth and temperature, the calculator 3003 can provide more accurate and reliable penetration detection results.

[0081] In the detection of the penetration degree of the cold rammer paste, the hammer body 200 is used to free fall along the connecting rod 100, so that the base plate 300 moves downward, the base plate 300 is used to drive the detection needle 400 to move downward, so that the detection needle 400 is inserted into the cold rammer paste, the first sensor 3002 is used to detect the depth of the needle penetration hole and send the depth to the calculator 3003, the second sensor 4001 is used to detect the temperature of the needle penetration hole and send the temperature to the calculator 3003, and the calculator 3003 is used to calculate the penetration degree of the cold rammer paste according to the depth and temperature.

[0082] The needle penetration detection device provided by the embodiment realizes accurate measurement of the needle penetration of cold ramming paste material through the combination of the mechanical structure of the integrated connecting rod, hammer body, bottom plate and detection needle, and the depth and temperature sensors. The needle penetration detection device achieves the following technical effects: by setting a second sensor on the other end of the detection needle, the device can monitor the temperature of the needle penetration hole in real time, thereby solving the problem of lack of temperature monitoring in traditional needle penetration detection devices and ensuring the accuracy of measurement results under different temperature conditions. Secondly, the first sensor provides digital depth measurement, reducing human measurement errors and improving measurement accuracy and reliability. Through these improvements, the accuracy and consistency of measurement are improved, and the operation process is simplified.

[0083] Figure 2 Structure diagram of the needle penetration detection device provided by the embodiment Figure 2 As shown in Figure 2 , the embodiment will be described in detail based on the Figure 1 embodiment.

[0084] The needle penetration detection device further comprises a fixed plate 500.

[0085] The bottom of the fixed plate 500 is connected to the other end of the connecting rod 100, and the fixed plate 500 is used to limit the movement range of the hammer body 200.

[0086] Specifically, the bottom of the fixed plate 500 can be connected to the other end of the connecting rod 100 by welding, bolt fixing or other mechanical connection methods. The fixed plate 500 can limit the movement range of the hammer body 200 on the connecting rod 100, preventing it from exceeding the preset track or height. This limitation ensures that the hammer body 200 is always in a controlled state during free fall, thereby improving the accuracy and safety of needle penetration detection.

[0087] The fixed plate 500 is provided with an electromagnet 5001 and a reset button 5002, the reset button 5002 is used to control the on-off of the electromagnet 5001, and the electromagnet 5001 is used to reset the hammer body 200 to the first position when powered on; wherein the first position refers to the position when the hammer body 200 contacts the electromagnet 5001.

[0088] Specifically, the fixed plate 500 is installed with an electromagnet 5001 and a reset button 5002. The reset button 5002 is used to control the energization state of the electromagnet 5001. When the electromagnet 5001 is energized, it will generate a magnetic force to attract the hammer body 200 to a first position on the fixed plate 500, i.e., the position where the hammer body 200 contacts the electromagnet 5001. This design is used to reset the hammer body 200 to the initial position after the detection operation is completed, in order to prepare for the next detection. In this way, it can be ensured that the hammer body 200 is in the same starting position at the beginning of each detection, thereby improving the accuracy and consistency of the detection results.

[0089] The fixed plate 500 is provided with a pull ring 5003 including a handle.

[0090] Specifically, the fixed plate 500 is installed with a pull ring 5003 including a handle. This pull ring 5003 is used to facilitate the user to move or adjust the position of the device when needed. By grabbing the handle of the pull ring, the user can more easily carry or reposition the entire device, especially when fine-tuning the detection position or moving the device from one working area to another. This design improves the portability and operational convenience of the device.

[0091] The side of the bottom plate 300 is also provided with a display screen 3004, which is used to display the penetration of the cold rammer paste calculated by the calculator 3003.

[0092] Specifically, the side of the bottom plate 300 is installed with a display screen 3004. The display screen 3004 is connected with the calculator 3003, and is used to display the penetration value of the cold rammer paste calculated by the calculator 3003 in real time. Through this design, the user can directly view the detection results on the display screen 3004 without additional equipment or steps, thereby improving the operational convenience and efficiency. This function enables the user to quickly obtain detection data, facilitating timely analysis and decision-making.

[0093] The side of the bottom plate 300 is also provided with a first indicator light 3005, a second indicator light 3006 and a third indicator light 3007, which are used to indicate the under-ramming state, ideal state and over-ramming state of the cold rammer paste, respectively, according to the penetration of the cold rammer paste calculated by the calculator 3003

[0094] Specifically, the side of the bottom plate 300 is mounted with a first indicator light 3005, a second indicator light 3006 and a third indicator light 3007. The state of the cold ramming paste can be judged according to the range in which the penetration is located, and the indicator lights are connected with the calculator 3003 and indicate the state according to the penetration of the cold ramming paste calculated by the calculator. Through this design, the user can quickly understand the current ramming state of the cold ramming paste by observing the state of the indicator light, so as to facilitate timely adjustment of process parameters and ensure product quality.

[0095] As shown in Figure 4 , Figure 4 is a schematic diagram of the change of the penetration at different temperatures at the same depth. When the penetration is in the first preset range, it indicates that the cold ramming paste is in an under-ramming state, and the first indicator light 3005 is on; when the penetration is in the second preset range, it indicates that the cold ramming paste is in an ideal state, and the second indicator light 3006 is on; when the penetration is in the third preset range, it indicates that the cold ramming paste is in an over-ramming state, and the third indicator light 3007 is on.

[0096] As shown in Figure 5 , Figure 5 is a schematic diagram of the change of the penetration at different depths and different temperatures. When the penetration is in the first preset range, it indicates that the cold ramming paste is in an under-ramming state, and the first indicator light 3005 is on; when the penetration is in the second preset range, it indicates that the cold ramming paste is in an ideal state, and the second indicator light 3006 is on; when the penetration is in the third preset range, it indicates that the cold ramming paste is in an over-ramming state, and the third indicator light 3007 is on.

[0097] The bottom plate 300 is also provided with a wireless communicator 3011, which is used to send the depth, temperature and penetration to an external device.

[0098] Specifically, the wireless communicator 3011 is mounted on the bottom plate 300. The wireless communicator 3011 is connected with the calculator 3003 and is used to wirelessly transmit the depth, temperature and penetration data obtained during the detection process to an external device, such as a computer, a smart phone or other data processing terminal. Through this design, the user can remotely monitor and record the detection data in real time, improving the convenience and flexibility of data management.

[0099] The first sensor 3002 is an ultrasonic sensor, and the second sensor 4001 is a sensor based on a thermistor.

[0100] Specifically, the first sensor 3002 adopts an ultrasonic sensor for measuring the depth of the needle entry hole formed after the insertion of the detection needle 400 into the cold rammer paste. The ultrasonic sensor determines the depth of the needle entry hole by emitting and receiving sound waves, which has the advantages of high precision and non-contact measurement. The second sensor 4001 adopts a sensor based on thermistor for measuring the temperature of the needle entry hole.

[0103] The second moving groove 3001 is provided with a reset spring 3008.

[0104] One end of the reset spring 3008 is connected to the connecting rod 100, and the other end of the reset spring 3008 is connected to the bottom plate 300. The reset spring 3008 is used to reset the bottom plate 300 to the second position; wherein the second position refers to the initial position of the bottom plate 300 under the action of no external force.

[0105] Specifically, the reset spring 3008 is installed in the second moving groove 3001, one end of which is connected to the connecting rod 100 and the other end of which is connected to the bottom plate 300. The reset spring 3008 can use the elastic restoring force of the spring to push the bottom plate 300 back to the second position, i.e. the initial position of the bottom plate 300 under the action of no external force, after the applied external force is removed during the detection process. This design can ensure that the bottom plate 300 and the detection needle 400 can automatically return to the starting position after each detection, thereby preparing for the next detection and improving the operation efficiency and continuous working ability of the device. In this way, the device can automatically reset without manual intervention, simplifying the operation process.

[0106] The second moving groove 3001 is provided with a limiting groove 3009.

[0107] Specifically, the limiting groove 3009 is designed to cooperate with the sliding piece 3010 on the connecting rod 100 to ensure that the bottom plate 300 slides along the preset path during movement. The sliding piece 3010 is installed at the end of the connecting rod 100 connected to the bottom plate 300, and slides in the limiting groove 3009 to provide a stable guide rail. This design can prevent the bottom plate 300 from deviating in directions other than the vertical direction, thereby ensuring the accuracy of the insertion angle and position of the detection needle 400 and improving the reliability and repeatability of the detection results.

[0108] The end of the connecting rod 100 connected to the bottom plate 300 is provided with a sliding piece 3010, and the connecting rod 100 is used to be slidingly connected with the limiting groove 3009 through the sliding piece 3010.

[0109] Specifically, one end of the connecting rod 100 is externally mounted with a sliding piece 3010. The sliding piece 3010 provides a precise guiding mechanism by cooperating with the limiting groove 3009, preventing the bottom plate 300 from deviating laterally or rotating during movement. This design can ensure that the detection needle 400 maintains the correct angle and position when inserted into the cold rammer paste, improving the accuracy and consistency of detection, while reducing errors caused by irregular movement.

[0110] The technical effect of the embodiment is that the reset spring is arranged in the second moving groove, realizing the automatic reset function of the bottom plate. Through automatic reset, the need for manual intervention is reduced, ensuring that the device can quickly prepare for the next detection after each detection, thereby improving the continuity and smoothness of the detection work; the limiting groove is arranged inside the second moving groove, and the sliding piece is arranged outside the end of the connecting rod connected with the bottom plate, realizing the sliding connection of the connecting rod and the limiting groove. This design can provide a precise guiding and limiting mechanism, ensuring that the bottom plate maintains stable straight-line movement during movement, preventing lateral deviation or rotation. This structure improves the movement accuracy and reliability of the detection device, ensuring that the detection needle can be accurately inserted into the cold rammer paste, thereby improving the accuracy of the penetration degree measurement.
