Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of sanding machines, and particularly relates to a wire mesh structure for detecting wear of a sanding machine cylinder. BACKGROUND
[0002] As an important industrial equipment, a sanding machine is widely used in the grinding and dispersion processes of various materials. One of the core components of the sanding machine, i.e., a cylinder, is inevitably worn out due to the strong impact and friction of materials and grinding media during a long-time operation. However, the current sanding machine has many deficiencies in the detection and management of the wear of the cylinder, 1. The wear of the cylinder cannot be visually observed during operation, and visual detection can only be performed after the contents are completely discharged; 2. The replacement of the cylinder requires a long downtime; 3. The wear condition cannot be grasped, and the situation of spare parts is more severe; 4. The operation parameters cannot be optimized according to the wear condition, and the efficiency of the whole machine cannot be guaranteed, which may cause damage to the auxiliary parts. Therefore, improvement is needed. CONTENT OF THE UTILITY MODEL
[0003] The application aims to provide a wire mesh structure for detecting wear of a sanding machine cylinder, which can solve the above problems.
[0004] The application aims to provide a wire mesh structure for detecting wear of a sanding machine cylinder, which comprises a horizontal sanding machine, an inner liner arranged in the horizontal sanding machine, a signal acquisition module and a control system, wherein the inner liner is provided with a wire mesh, the wire mesh is connected with the signal acquisition module and the control system, the wire mesh is arranged in the inner liner in a pre-buried manner, and the wire mesh can indicate the wear area of the cylinder liner rubber layer in the operation cycle and remind the operator when the thickness of the cylinder liner rubber layer is worn to a predetermined amount.
[0005] The wire mesh structure for detecting wear of a sanding machine cylinder comprises a main shaft supporting assembly, a cylinder assembly supported by a base, the cylinder assembly comprising a cylinder, a cylinder liner and a discharge end cover. A main shaft assembly is arranged at the center of the main shaft supporting assembly, and has a plurality of drive shafts of grinding discs and a mechanical seal device fixed to the feed end cover. The drive shafts can rotate around the central axis in the clockwise or counterclockwise direction. The grinding discs are spaced apart in any manner in the axial direction, and can be spaced more closely along the outlet side of the cylinder assembly, and a grading wheel is installed on the end face. The main shaft supporting assembly comprises a first main shaft support, a second main shaft support and a main shaft support base.
[0006] The main shaft assembly is fixed by the first main shaft support and the second main shaft support in a single-end double support point and bidirectional manner, and is arranged in a cantilever manner on the grinding disc in the barrel assembly. The inner side of the barrel is a barrel liner, which is distributed in the radial direction and sequentially includes an inner liner steel plate and an inner liner. The ore pulp enters the barrel through the feed port and rotates around the central axis under the driving of the grinding disc, and is finally discharged from the barrel through the ore discharge screen fixed to the discharge end cover under the action of the classification wheel.
[0007] In the present application, the wire mesh is pre-embedded in the inner liner by casting or gluing, etc. for real-time monitoring of the wear condition of the inner liner, so it will not fall off or loosen due to wear. At the same time, the wire mesh can indicate the wear area of the barrel lining rubber layer during the operation cycle. When the wires in a certain area are broken or the signal changes due to wear, it can be judged that the area has been worn. Through the signal change of the wire mesh, the remaining thickness of the barrel lining rubber layer can be calculated, and when the remaining thickness decreases to a predetermined amount, the system will remind the operator to maintain or replace. The signal acquisition module is used to receive the signal transmitted by the wire mesh and convert it into identifiable data, including the position of the wear area, the degree of wear, and the remaining thickness of the lining rubber layer, etc. The control system processes and analyzes the data transmitted by the signal acquisition module. When the wear condition reaches the preset threshold, the control system will issue a warning signal to remind the operator to take appropriate maintenance measures, such as replacing the barrel liner.
[0008] According to the wear data provided by the wire mesh, a more reasonable maintenance plan can be developed to reduce unnecessary downtime and maintenance costs. By timely maintenance and replacement of severely worn parts, the service life of the entire sand mill barrel can be extended.
[0009] Further, the wire mesh is provided with multiple groups.
[0010] According to the size, shape and wear detection requirements of the sand mill barrel, multiple groups of wire meshes can be designed and arranged to form a comprehensive wear monitoring network. Multiple groups of wire meshes can cover more areas of the barrel, thereby more accurately reflecting the wear condition of the barrel and more accurately determining the location and degree of wear.
[0011] Further, one end of the wire mesh is a single signal input port, and the signal is introduced through the signal input port, and the wire mesh is distributed in multiple layers in the radial direction through different thicknesses of predetermined amounts.
[0012] The design of the single signal input port greatly simplifies the connection between the wire mesh and the model collection module and the control system, and there is no need to set up independent signal lines for each wire mesh unit, thereby reducing the complexity and cost of the system. By introducing signals through the single signal input port, it can be ensured that all wire mesh units receive the same signals, thereby improving the reliability and consistency of the entire detection system. The design of the single signal input port also facilitates system maintenance and troubleshooting. Once a problem occurs, the signal input port and its related connection parts can be quickly located, and the problem can be quickly solved.
[0013] The wire mesh is distributed in multiple layers along the radial direction with different thicknesses, which can achieve more precise monitoring of the wear of the rubber layer of the cylinder and more accurately judge the wear state of the cylinder. Since the wear degree of different parts of the cylinder may be different during operation, the multi-layer distributed wire mesh can better adapt to such differences. When the wire mesh of a certain layer is broken or the signal changes due to wear, the wear degree of the region can be immediately judged, and appropriate maintenance measures can be taken.
[0014] Further, the wire mesh is distributed in multiple radial lines along the axial direction according to the length of the cylinder, and the wires in the same radial layer are mirror distributed along the central axis surface, and the ends of the wires are signal output ports.
[0015] The wire mesh is distributed in multiple radial lines along the length direction of the cylinder, which can ensure that the wear of each axial position of the cylinder can be effectively monitored, avoiding the problem of missed detection due to monitoring blind spots, and improving the comprehensiveness of the detection. Each radial wire mesh corresponds to a specific area on the cylinder, and when the wire in a certain area is broken or the signal changes due to wear, the area can be quickly located, thereby achieving accurate judgment of the wear position. In the same radial layer, the wires are mirror distributed along the central axis surface, which can ensure that the wear of the symmetrical positions on both sides of the cylinder can be evenly monitored, avoiding the problem of misjudgment due to uneven wear on both sides of the cylinder, and improving the accuracy of the detection. The mirror distribution design can also optimize the layout of the wire mesh to some extent, making the distribution of the wire mesh in the cylinder more uniform and reasonable. This not only improves the detection efficiency, but also reduces the failure rate of the wire mesh due to improper layout.
[0016] The ends of the wires as signal output ports can transmit wear signals to the control system in real time for processing and analysis, so that the control system can quickly respond to the wear condition and timely issue a warning signal to provide decision support for the operator. The design of the signal output port also facilitates system maintenance and troubleshooting. Once a wire fails or the signal is abnormal, the signal output port of the wire can be quickly located, and the problem can be quickly solved to restore normal operation of the system.
[0017] Further, the inner liner is divided into axial regions by different lengths of the first wires in the wire mesh. The regions include region a with four first wires, region b with three first wires, region c with two first wires, and region d with one first wire. The wear region distribution of the cylinder liner can be listed according to the signal on-off combination between the signal input port and each branch of the first wire.
[0018] The inner liner is divided into axial regions by the first wires in the wire mesh. The first wires have different lengths and extend to different positions along the axial direction of the cylinder from the signal input port, thereby dividing the cylinder into multiple axial regions. According to the number of first wires, the regions are divided into different types. Specifically, region a with four first wires, region b with three first wires, region c with two first wires, and region d with one first wire, improve the detection accuracy and reliability.
[0019] When the rubber layer of the cylinder liner is worn, the first wire in the corresponding region may be broken or the signal may change. By monitoring the signal state (on or off) of these wires, the wear of the rubber layer of the cylinder liner can be obtained. Since each region contains a different number of first wires, the wear region can be uniquely determined by the signal on-off combination. Based on the signal on-off combination between the signal input port and each branch of the first wire, an exhaustive analysis can be performed, i.e., all possible signal on-off combinations are listed and correspond to the wear region distribution of the cylinder liner. In this way, no matter which region of the cylinder liner is worn, the signal on-off combination can accurately determine the wear region.
[0020] During the operation of the sand mill, when the rubber layer of a certain region is worn, the corresponding wire signal will change. By monitoring these signal changes and combining the results of the exhaustive analysis, the wear region can be quickly located, and appropriate maintenance measures can be taken. This not only improves the efficiency of the equipment, but also reduces maintenance costs and safety risks.
[0021] Further, the inner liner is divided into different thickness radial regions by different radial distribution heights of the second wires in the wire mesh. The divided regions are thickness layer a, thickness layer b, thickness layer c, and thickness layer d.
[0022] Among them, thickness layer a has the smallest distribution diameter and is closer to the center axis. Thickness layer d serves as a preset wear threshold, and its distribution height should be carefully considered to achieve the longest service life of the cylinder liner without negatively affecting the operation of the equipment
[0023] The cylinder liner is divided into a plurality of thickness layers by different distribution heights of the second wire in the radial direction, and the thickness layers are sequentially increased from the center axis and are marked as thickness layer a, thickness layer b, thickness layer c and thickness layer d. The thickness layer a is closer to the center axis. The thickness layer d is a preset wear threshold area, and the distribution height and thickness of the thickness layer d need to be carefully considered. The wear threshold of the thickness layer d is determined according to the use conditions, material properties and expected service life of the cylinder, and the threshold can accurately reflect the wear degree of the cylinder liner and give an early warning of potential wear problems.
[0024] In the present application, the signal is input through the signal input port, and the on-off relationship between each branch and the signal input port is operatively collected by the switch signal collection module. As the liner wears, its inner diameter will gradually enlarge to the inner diameter size of the liner steel plate. As a result, at least one wire will be consumed during the grinding process in the actual operation process, and one or more signals provided by the switch signal collection module to the control system will be changed or no longer generated. The change of one or more signals indicates that the liner has worn more than one or more regions, one or more thicknesses of a predetermined amount. For example, if the passage signal between the signal input port and the first wire disappears, it means that the thickness layer a in the region a has been worn.
[0025] When the number of signals or the combination of signals provided to the control system reaches a predetermined setting, the operator can be prompted about the running state of the sand mill and its components by starting an audible and visual alarm signal. The indicator can be provided in any way to adjust the sand mill operating parameters such as filling rate, pulp concentration, pulp flow or main shaft speed before the liner wears or fails, or stop the sand mill from running, or maintain the sand mill, or replace the cylinder liner.
[0026] The beneficial effects of the present application are:
[0027] 1. By providing a wire mesh, a liner thickness continuous monitoring device and method for the service life of the sand mill cylinder liner can be provided to remind the operator when the rubber layer thickness of the cylinder wears to a predetermined amount, and then reasonably arrange the maintenance period;
[0028] 2. By providing a wire mesh, the operator can be instructed about the wear area of the rubber layer of the cylinder during the running cycle, so as to optimize the equipment operating parameters, prolong the service life of the parts, and improve the grinding circuit efficiency;
[0029] 3. By providing a guide net, the replacement efficiency of the cylinder can be improved, and the wear condition of the cylinder can be visually detected without discharging all the contents; BRIEF DESCRIPTION OF DRAWINGS

[0041] The detection wear wire mesh structure of the sand mill cylinder provided by the embodiments of the present application will be described in detail below in combination with the drawings, specific embodiments and application scenarios.
[0042] Embodiment 1:
[0043] As Figures 1 to 6 shown, the embodiments of the present application provide a detection wear wire mesh structure of a sand mill cylinder, which comprises a horizontal sand mill 100, an inner liner 200 arranged in the horizontal sand mill, a signal acquisition module 300 and a control system 400: the inner liner 200 is provided with a wire mesh 500, the wire mesh 500 is connected with the signal acquisition module 300 and the control system 400, the wire mesh 500 is arranged in the inner liner 200 by pre-embedding, the wear area of the cylinder 121 in the running cycle of the rubber lining layer can be indicated by the wire mesh 500, and the operator is reminded when the rubber lining layer of the cylinder 121 is worn to the predetermined amount.
[0044] In some embodiments of the present application, as Figure 1 shown, the detection wear wire mesh 500 structure of the sand mill cylinder 121 is used, the horizontal sand mill comprises a main shaft supporting assembly 110, a cylinder assembly 120 supported by a base 130, the cylinder assembly 120 comprises a cylinder 121, an inner liner 200 of the cylinder 121, and a discharge end cover 123. A main shaft assembly 140 is arranged at the center of the main shaft supporting assembly 110, and has a driving shaft 142 with a plurality of grinding discs 141 and a mechanical seal device 144 fixed to a feed end cover 124, the driving shaft 142 can rotate around the central axis 150 in clockwise or counterclockwise direction. The grinding discs 141 are spaced in any way in the axial direction, and can use closer spacing along the outlet 170 side of the cylinder assembly 120, and a step wheel 143 is installed on the end face. The main shaft supporting assembly 110 comprises a first main shaft support 111, a second main shaft support 112 and a main shaft support base 130 113.
[0045] The main shaft assembly 140 is fixed by the first main shaft support 111 and the second main shaft support 112 in a single-end double-support two-way manner, and is arranged in a cantilevered manner in the barrel assembly 120 with the grinding disc 141 thereon. The inside of the barrel 121 is lined with the barrel liner 200, which is distributed in the radial direction and sequentially includes the liner steel plate 1221 and the liner 200. The ore pulp enters the barrel 121 through the feed inlet 160, is driven by the grinding disc 141 to rotate around the central axis 150, and is finally discharged from the barrel 121 through the ore discharge screen fixed to the discharge end cover 123 under the action of the classification wheel 143.
[0046] In the present application, the wire mesh 500 is embedded in the liner 200 by casting or gluing, etc., for real-time monitoring of the wear condition of the liner 200, so that it will not fall off or loosen due to wear. At the same time, the wire mesh 500 can indicate the wear area of the rubber lining of the barrel 121 during the operation cycle. When the wires in a certain area are broken or the signal changes due to wear, it can be judged that the area has been worn. Through the signal change of the wire mesh 500, the remaining thickness of the rubber lining of the barrel 121 can be calculated, and when the remaining thickness decreases to a predetermined amount, the system will remind the operator to maintain or replace. The signal acquisition module 300 is used to receive the signal transmitted by the wire mesh 500 and convert it into identifiable data, including the position of the wear area, the degree of wear, and the remaining thickness of the rubber lining, etc. The control system 400 processes and analyzes the data transmitted by the signal acquisition module 300. When the wear condition reaches the preset threshold, the control system 400 will issue a warning signal to remind the operator to take appropriate maintenance measures, such as replacing the barrel liner 200.
[0047] According to the wear data provided by the wire mesh 500, a more reasonable maintenance plan can be developed to reduce unnecessary downtime and maintenance costs. Through timely maintenance and replacement of severely worn parts, the service life of the entire sand mill barrel 121 can be extended.
[0048] Embodiment 2:
[0049] The embodiment of the present application provides a wire mesh structure for detecting wear of a sand mill barrel. In addition to the above technical features, the wire mesh structure for detecting wear of the sand mill barrel of the embodiment of the present application further comprises the following technical features.
[0050] As shown in Figure 1 , Figure 2 , Figures 3 to 6 indicates that the wire mesh 500 is provided with a plurality of groups.
[0051] In the embodiments of the present application, according to the size and shape of the sand mill cylinder 121 and the requirement of wear detection, multiple groups of wire meshes 500 can be designed and arranged to form a comprehensive wear monitoring network. The multiple groups of wire meshes 500 can cover more areas of the cylinder 121, thereby more accurately reflecting the wear condition of the cylinder 121 and more accurately determining the location and degree of wear.
[0052] Embodiment 3:
[0053] The embodiments of the present application provide a wire mesh structure for detecting wear of a sand mill cylinder. In addition to the above technical features, the wire mesh structure for detecting wear of the sand mill cylinder according to the embodiments of the present application further comprises the following technical features.
[0054] As shown in Figure 1 , Figure 2 , Figures 3 to 7 , one end of the wire mesh 500 is a single signal input port 510, and the signal is introduced through the signal input port 510, and the wire mesh 500 is distributed in multiple layers along the radial direction with different thicknesses.
[0055] In the embodiments of the present application, the design of the single signal input port 510 greatly simplifies the connection between the wire mesh 500 and the model collection module and the control system 400, and there is no need to set up independent signal lines for each wire mesh 500 unit, thereby reducing the complexity and cost of the system. By introducing the signal through the single signal input port 510, it can be ensured that all wire mesh 500 units receive the same signal, thereby improving the reliability and consistency of the entire detection system. The design of the single signal input port 510 also facilitates the maintenance and troubleshooting of the system. Once a problem occurs, the signal input port 510 and its related connection parts can be quickly located, thereby quickly solving the problem.
[0056] The wire mesh 500 is distributed in multiple layers along the radial direction with different thicknesses, which can achieve more fine monitoring of the wear condition of the rubber layer of the cylinder 121 and more accurately judge the wear state of the cylinder 121. Since the wear degree of different parts of the cylinder 121 may be different during operation, the wire mesh 500 distributed in multiple layers can better adapt to such differences, and when the wire mesh 500 of a certain layer is broken or the signal changes due to wear, the wear degree of the region can be immediately judged, and corresponding maintenance measures can be taken.
[0057] Further, the wire mesh 500 is distributed in multiple radial lines along the axial direction according to the length of the cylinder 121, and the wires in the same radial layer are mirror distributed along the central axis surface, and the ends of the wires are signal output ports 520.
[0058] The wire mesh 500 is distributed in a multi-strand radial pattern along the length of the cylinder 121, ensuring effective monitoring of wear at all axial positions of the cylinder 121. This avoids missed detections due to blind spots and improves the comprehensiveness of the inspection. Each radial wire mesh 500 corresponds to a specific area on the cylinder 121. When a wire in a certain area breaks due to wear or the signal changes, that area can be quickly located, enabling accurate judgment of the wear location. Within the same radial layer, the wires are mirror-distributed along the central axis, ensuring balanced monitoring of wear at symmetrical positions on both sides of the cylinder 121. This avoids misjudgments caused by uneven wear on both sides of the cylinder 121 and improves inspection accuracy. The mirror-distribution design also optimizes the layout of the wire mesh 500 to a certain extent, making its distribution within the cylinder 121 more uniform and reasonable. This not only improves inspection efficiency but also reduces the failure rate caused by improper layout of the wire mesh 500.
[0059] Each conductor's end serves as a signal output port 520, transmitting wear signals to the control system 400 in real time for processing and analysis. This allows the control system 400 to respond quickly to wear conditions, issue timely warning signals, and provide decision support for the operator. The design of the signal output port 520 also facilitates system maintenance and troubleshooting. If a conductor malfunctions or experiences a signal anomaly, the signal output port 520 of that conductor can be quickly located, thereby rapidly resolving the problem and restoring the system to normal operation.
[0060] Example 4:
[0061] This application provides a wire mesh structure for detecting wear on a sand mill cylinder. In addition to the above-mentioned technical features, the wire mesh structure for detecting wear on a sand mill cylinder in this application also includes the following technical features.
[0062] like Figure 7 As shown, the inner liner 200 is divided into axial regions by first conductors 530 of different lengths in the conductor network 500. Each region along the axial direction includes a region a600 with four first conductors 530, a region b610 with three first conductors 530, a region c620 with two first conductors 530, and a region d630 with one first conductor 530. The wear area distribution of the inner liner 200 of the cylinder 121 can be enumerated based on the signal on / off combinations between the signal input port 510 and each branch of the first conductor 530.
[0063] In the embodiment of the present application, the inner liner 200 is divided into axial regions by the first wires 530 in the wire mesh 500, and the first wires 530 have different lengths and extend axially along the cylinder 121 to different positions from the signal input port 510, thereby dividing the cylinder 121 into multiple axial regions. According to the number of first wires 530, the regions are divided into different types. Specifically, the region a 600 includes four first wires 530, the region b 610 includes three first wires 530, the region c 620 includes two first wires 530, and the region d 630 includes one first wire 530, thereby improving the accuracy and reliability of detection.
[0064] When the rubber lining of the cylinder 121 is worn, the first wires 530 in the corresponding region may be broken or the signal may change. By monitoring the signal state (on or off) of the wires, the wear condition of the rubber lining of the cylinder 121 can be obtained. Since each region contains a different number of first wires 530, the wear region can be uniquely determined by the signal on-off combination. Based on the signal on-off combination between the signal input port 510 and each branch of the first wire 530, an exhaustive analysis can be performed, that is, all possible signal on-off combination conditions are listed and correspond to the wear region distribution of the inner liner 200 of the cylinder 121. In this way, no matter which region of the cylinder 121 the rubber lining is worn, it can be accurately determined by the signal on-off combination.
[0065] During the operation of the sand mill, when the rubber lining of a certain region is worn, the corresponding wire signal will change. By monitoring these signal changes and combining the results of the exhaustive analysis, the wear region can be quickly located, and appropriate maintenance measures can be taken, which not only improves the operation efficiency of the equipment, but also reduces the maintenance cost and safety risk.
[0066] Embodiment 5:
[0067] The embodiment of the present application provides a wire mesh structure for detecting wear of a sand mill cylinder, in addition to the above technical features, the wire mesh structure for detecting wear of the sand mill cylinder of the embodiment of the present application further comprises the following technical features.
[0068] As shown in Figure 8 , the inner liner 200 is divided into radial regions of different thicknesses by the second wires 540 in the wire mesh 500 with different radial distribution heights, and the divided regions are: thickness layer a 700, thickness layer b 710, thickness layer c 720, and thickness layer d 730.
[0069] Among them, the thickness layer a 700 is distributed with the smallest diameter, which is closer to the center axis 150.
[0070] In the embodiments of the present application, the second wire 540 in the wire mesh 500 is used to divide the liner 200 into a plurality of thickness layers with different distribution heights in the radial direction, which are sequentially increased from the center axis 150 and marked as thickness layer a 700, thickness layer b 710, thickness layer c 720 and thickness layer d 730. The thickness layer a 700 is closer to the center axis 150. The thickness layer d 730 is a preset wear threshold area, and its distribution height and thickness need to be carefully considered. The wear threshold of the thickness layer d 730 should be determined according to the use conditions, material properties and expected service life of the cylinder 121 and other factors. This threshold should accurately reflect the wear degree of the liner 200 of the cylinder 121 and provide early warning of potential wear problems.
[0071] Embodiment 6:
[0072] The embodiments of the present application provide a wire mesh structure for detecting wear of a sand mill cylinder. In addition to the above technical features, the wire mesh structure for detecting wear of the sand mill cylinder of the embodiments of the present application further comprises the following technical features.
[0073] In the present application, as shown in Figures 1 to 3 After the signal is input through the signal input port 510, the on-off relationship between each branch and the signal input port 510 can be collected by the switch signal collection module 300. As the liner 200 wears, its inner diameter will gradually increase to the inner diameter size of the liner steel plate 1221. As a result, at least one wire will be consumed during the grinding process in the actual operation process. Therefore, one or more signals provided by the switch signal collection module 300 to the control system 400 will be changed or no longer generated. The change of one or more signals indicates that the liner 200 has been worn beyond one or more regions, one or more thicknesses of a predetermined amount. For example, the disappearance of the passage signal between the signal input port 510 and the first wire 530 indicates that the thickness layer a 700 in the region a 600 has been worn.
[0074] When the number of signals or the combination of signals provided to the control system 400 reaches a predetermined setting, an audible and visual alarm signal can be started to prompt the operator about the running state of the sand mill and its components. An indicator can be provided in any way to adjust the sand mill operating parameters such as filling rate, ore pulp concentration, ore pulp flow rate or main shaft speed before the liner 200 wears or fails, or to stop the sand mill from running, or to maintain the sand mill, replace the liner 200 of the cylinder 121, etc.
