Description

Technical Field

[0001] The invention belongs to the technical field of material crushing, and in particular relates to a roller press with a side baffle wear detection function. Background Art

[0002] The roller press is a mechanical device that crushes products. During long-term use, it will produce obvious wear and tear, causing the thickness of key structures to decrease, posing a great risk to the safe operation of the equipment.

[0003] In a Chinese patent with the announcement number CN 118287205 A, a retractable wear self-detecting side baffle for a roller press feed device is disclosed: a wear-resistant composite liner, which is slidably fitted on the outer periphery of the frame; a driving mechanism, which is arranged in the cavity of the end face sealing back plate, and is used to push the wear-resistant composite liner to move along the roller axial direction; and a detection module, which includes a detection probe, which is fixedly embedded on a side of the wear-resistant composite liner away from the driving mechanism; wherein the driving mechanism drives the wear-resistant composite liner to move horizontally to fill the wear gap caused by wear according to the wear amount of the wear-resistant composite liner detected by the detection module;

[0004] However, the above device has the following problems during use:

[0005] The driving mechanism can drive the wear-resistant composite lining plate to move horizontally to fill the wear gap caused by wear, so that the front side of the wear-resistant composite lining plate is always blocked between the two rollers (equivalent to the rollers). However, the side of the wear-resistant composite lining plate close to the roller, that is, the side of the wear-resistant composite lining plate is also a severely worn area. In the process of the roller crushing the material, the material will squeeze the side of the wear-resistant composite lining plate. The side of the wear-resistant composite lining plate is prone to wear and the gap between the roller is too large, resulting in material leakage.

[0010] A side detection feeding unit is arranged inside the inner plate, and the side detection feeding unit includes two wear-resistant side plates. The two wear-resistant side plates are arranged at two side edges of the inner plate close to the outer walls of the two rollers. The side detection feeding unit is used to detect the thickness of the wear-resistant side plates. After detecting that the thickness of the wear-resistant side plates becomes thinner, the side detection feeding unit pushes the inner plate to move toward the side close to the rollers.

Multiple electromagnetic ultrasonic detection sensors can measure the wall thickness at multiple points of the wear-resistant side plate, and judge the wear condition of the wear-resistant side plate according to the measured data. If the wear exceeds the set value, the wear-resistant side plate can be pushed to the side close to the outer wall of the roller through the side detection feeding unit, shortening the distance between the wear-resistant side plate and the outer wall of the roller, so that the side that is prone to wear can be compensated for the distance according to the wear condition, thereby extending the service life of the inner plate.

[0022] 2. The present invention starts the contraction power unit in the replacement unit, so that the lower wear-resistant plate is converted to a contracted state, and then the winding device is started, and the connecting rope thereon pulls the lower wear-resistant plate up, and the other end of the connecting rope is loosened, and the upper wear-resistant plate moves down under the action of gravity, and finally the upper wear-resistant plate falls to the position of the original lower wear-resistant plate, and then the contraction power unit is started to convert the lower wear-resistant plate to an expanded state. At this time, the positions of the lower wear-resistant plate and the upper wear-resistant plate are swapped. After the positions of the lower wear-resistant plate and the upper wear-resistant plate are swapped, after being used again for a certain period of time, the overall degree of wear of the two is roughly the same. With the moving device that can drive the lower wear-resistant plate and the upper wear-resistant plate to move, the lower wear-resistant plate and the upper wear-resistant plate can maintain synchronous wear, so that the inner plate as a whole can be used for a longer time before being replaced, which can extend the service life of the inner plate.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Reference Figure 1-Figure 3 A roller press with a side baffle wear detection function comprises a roller 1, a support device 2, a feeding frame 3, a track plate 4, an inner plate 5, and an outer plate 6;

[0036] Both ends of the roller 1 are inserted into two supporting devices 2. A working area is provided between the two rollers 1. The working area is used as an area for extruding materials. The two rollers 1 extrude the materials in the working area to crush the materials. A feeding frame 3 is located above the working area. The feeding frame 3 is provided on a track plate 4. The track plate 4 is provided on the supporting device 2.

[0037] The loading frame 3 feeds the material into the component in the working area so that the material falls between the two rollers 1 .

[0038] Reference Figure 4 , Figure 5 The inner plate 5 is arranged on the outer plate 6, and the inner plate 5 is inserted between the two rollers 1. There is a gap between the inner plate 5 and the outer wall of the roller 1. The gap is to avoid mutual wear between the inner plate 5 and the rotating roller 1. The two inner plates 5 are respectively located on both sides of the working area to seal the working area to prevent the material from leaving the working area and thus being unable to be crushed by the roller 1.

[0039] The outer plate 6 is connected to a moving device 7 for controlling the insertion depth of the inner plate 5 between the two rollers 1; the moving device 7 can drive the outer plate 6 to move, and then drive the inner plate 5 to move, and adjust the insertion depth of the inner plate 5 into the two rollers 1. The depth can be determined according to the amount of material entering the working area, so that the inner plate 5 can prevent the material from moving outward and allow the material to be crushed in the working area.

[0040] When the two rollers 1 are crushing the materials, they will squeeze the materials, and the squeezed materials will wear against the inner plate 5, which will cause the inner plate 5 to become thinner and unable to block the materials normally. The inner plate 5 is prone to wear and tear usually on the side of the inner plate 5 (i.e., the outer wall of the inner plate 5 close to the outer wall of the roller 1) and the bottom area of ​​the front of the inner plate 5 (i.e., the area where the distance between the two rollers 1 is the narrowest, which can be referred to Figure 1 , Figure 3 , which is the position of the lower wear-resistant plate 9. )

[0041] In order to detect the side of the inner plate 5 which is easily worn and compensate for the side of the inner plate 5 after wear, a side detection feeding unit 8 is arranged in the inner plate 5. The side detection feeding unit 8 includes two wear-resistant side plates 801. The two wear-resistant side plates 801 are arranged at two side edges of the inner plate 5 close to the outer walls of the two rollers 1. The side detection feeding unit 8 is used to detect the thickness of the wear-resistant side plate 801. After detecting that the thickness of the wear-resistant side plate 801 becomes thinner (due to wear with the material), the side detection feeding unit 8 pushes the inner plate 5 to move toward the side close to the roller 1.

[0042] Specifically, the side detection feeding unit 8 also includes a side detection module 803, which can be a thickness sensor. A side detector mounting groove 802 is provided in the wear-resistant side plate 801, and multiple side detection modules 803 are dispersedly installed in the side detector mounting groove 802. Specifically, the side detection module 803 can be an electromagnetic ultrasonic detection sensor, which is provided in the side detector mounting groove 802. Multiple electromagnetic ultrasonic detection sensors can measure the wall thickness at multiple points in the wear-resistant side plate 801, and the electromagnetic ultrasonic detection sensor can withstand online measurement at a high temperature of 100° for a long time. The wear condition of the wear-resistant side plate 801 is judged according to the measured data. If the wear exceeds the set value, the wear-resistant side plate 801 can be pushed to the side close to the outer wall of the roller 1 by the side detection feeding unit 8 to shorten the distance between the wear-resistant side plate 801 and the outer wall of the roller 1. At this time, the worn wear-resistant side plate 801 can still block the material in the working area;

[0043] Multiple electromagnetic ultrasonic detection sensors are connected to a four-channel thickness gauge, which processes and analyzes the data of the electromagnetic ultrasonic detection sensors and calculates the wall thickness test results. The four-channel thickness gauge is connected to the control system through RS485 and can be connected to the PLC, which can simultaneously upload thickness measurement and waveform data. The control system is equipped with a data server to display the wall thickness and waveform results uploaded by the four-channel thickness gauge. At the same time, the detection parameters of the thickness gauge can be set through the software to achieve accurate measurement of the thickness value.

[0044] The electromagnetic ultrasonic testing device is mainly composed of three parts: high-frequency coil, external magnetic field and the test piece itself. Figure 4 As shown. When a high-frequency current passes through the high-frequency coil placed on the surface of the workpiece, it will generate eddy currents in the skin layer of the workpiece. Under the action of the external magnetic field, this eddy current will be affected by mechanical force and produce high-frequency vibrations, forming an ultrasonic wave source. When receiving ultrasonic waves, the oscillation of the workpiece surface will also induce voltage in the high-frequency coil under the action of the external magnetic field force and be received by the instrument.

[0045] (1) The energy conversion of electromagnetic ultrasonic testing is carried out directly in the skin layer of the workpiece surface. Since the skin layer is the surface layer of the workpiece, the ultrasonic wave generated by electromagnetic ultrasonic does not require any coupling medium;

[0046] (2) Electromagnetic ultrasound can transmit and receive ultrasonic waves without contacting the material in which the sound waves propagate. Therefore, special cleaning of the surface of the workpiece is not required, and rough surfaces can also be directly detected.

[0047] (3) One of the biggest advantages of electromagnetic ultrasound over conventional ultrasound is its non-contact nature. The temperature field radiated by a hot body in space decays exponentially. As the probe is lifted a certain distance from the surface of the test piece, the ambient temperature of the probe decreases significantly. Therefore, electromagnetic ultrasound can be used for high-temperature workpiece inspection.

[0048] Long-term vibration of the detection components may interfere with the detection data results. The equipment filters the vibration interference from both the installation structure and the detection algorithm to ensure detection accuracy.

[0049] (1) Structural method: Set the sensor's vibration-absorbing installation angle to reduce the impact of vibration.

[0050] (2) Algorithm: Through professional filtering algorithms, the noise interference caused by vibration is eliminated, the signal-to-noise ratio is improved, and the echo waveform is accurately identified.

[0051] (3) Thickness measurement data.

[0052] More specifically, the wear-resistant side plate 801 is connected to a side feeding device 804, which is used to push the wear-resistant side plate 801 to move toward the side close to the outer wall of the roller 1 or away from the outer wall of the roller 1. In order to make the wear-resistant side plate 801 more stable when subjected to force, a side groove 501 is provided in the inner plate 5, and the wear-resistant side plate 801 is plugged into the side groove 501.

[0053] Reference Figure 6-Figure 8 In order to detect the narrowest area in the middle of the roller 1 which is easy to wear and replace the worn lower wear-resistant plate 9 according to the detection result, a lower wear-resistant plate 9, an upper wear-resistant plate 10 and a replacement unit 11 are arranged on the inner plate 5, and the lower wear-resistant plate 9 is located at the narrowest interval area between the two rollers 1;

[0054] Specifically, the lower wear-resistant plate 9 and the upper wear-resistant plate 10 are both provided with front wall thickness detection modules 12. The multiple front wall thickness detection modules 12 are respectively used to measure the wall thickness of the lower wear-resistant plate 9 and the upper wear-resistant plate 10. The thickness of the lower wear-resistant plate 9 and the upper wear-resistant plate 10 is judged according to the value of the wall thickness. The front wall thickness detection module 12 can also adopt an electromagnetic ultrasonic detection sensor. The lower wear-resistant plate 9 is located in the area where the distance between the two rollers 1 is the narrowest. The lower wear-resistant plate 9 is worn much faster than the upper wear-resistant plate 10. When the front wall thickness detection module 12 detects that the thickness of the lower wear-resistant plate 9 is too thin (that is, the lower wear-resistant plate 9 is worn too much), the replacement unit 11 swaps the positions of the lower wear-resistant plate 9 and the upper wear-resistant plate 10. The upper wear-resistant plate 10 is moved to the area with the narrowest spacing between the two rollers 1, and the lower wear-resistant plate 9 is moved to the original position of the upper wear-resistant plate 10. In this way, the two wear-resistant plates share the work, and the degree of wear of the upper and lower parts in the middle area of ​​the inner plate 5 tends to be the same, that is, the degree of wear of the two wear-resistant plates tends to be the same. The two wear-resistant plates work separately in the severely worn area between the rollers 1, thereby extending the overall service life of the inner plate 5. At the same time, the two wear-resistant plates can be moved deeper into the working area through the moving device 7 after being worn, and the material sealing work in the working area can still be performed.

[0055] Specifically, the replacement unit 11 includes a winding device 1101, and a connecting rope is arranged in the winding device 1101, one end of the connecting rope is connected to the upper wear-resistant plate 10, and the other end of the connecting rope is connected to the inner frame 1102; one end of the connecting rope moves downward, and the other end moves upward;

[0056] More specifically, the inner frame 1102 is provided with a first square frame 1103 and a second square frame, the first square frame 1103 is provided with a first square groove, the first square groove is inserted with a first connecting rod, the first connecting rod is plugged with a first inclined plate 1104, the first inclined plate 1104 is inserted with an intermediate shaft 1106, the intermediate shaft 1106 is plugged with a second inclined plate 1105, the second connecting rod is inserted into the top of the second inclined plate 1105, the second connecting rod is plugged with a second square groove, the second square groove is provided inside the second frame, and the intermediate shaft 1106 is connected with a contraction power unit 1107;

[0057] The contraction power unit 1107 can push the intermediate shaft 1106 to move up and down, and the intermediate shaft 1106 moves upward. The first inclined plate 1104 and the second inclined plate 1105 move around the intermediate shaft 1106 toward each other, and the lower wear-resistant plate 9 is in a contracted state. At this time, the lower wear-resistant plate 9 and the upper wear-resistant plate 10 are staggered up and down. The contraction power unit 1107 pushes the intermediate shaft 1106 to move downward, and the first inclined plate 1104 and the second inclined plate 1105 move around the intermediate shaft 1106 away from each other. At this time, the lower wear-resistant plate 9 is in an expanded state, and the lower wear-resistant plate 9 and the upper wear-resistant plate 10 are aligned up and down.

[0058] When the front wall thickness detection module 12 measures that the thickness of the lower wear-resistant plate 9 is less than a certain value of the thickness of the upper wear-resistant plate 10, the replacement unit 11 is started, and the retraction power unit 1107 is started, so that the lower wear-resistant plate 9 is converted to a retracted state, and then the winding device 1101 is started, and the connecting rope thereon pulls the lower wear-resistant plate 9 upward. During the process, the other end of the connecting rope is loosened, and the upper wear-resistant plate 10 moves downward under the action of gravity, and finally the upper wear-resistant plate 10 falls to the position of the original lower wear-resistant plate 9, and the lower wear-resistant plate 9 moves to the height of the original upper wear-resistant plate 10, and then the retraction power is started. Unit 1107 allows the lower wear-resistant plate 9 to be converted into an expanded state. At this time, the positions of the lower wear-resistant plate 9 and the upper wear-resistant plate 10 are swapped, and the upper wear-resistant plate 10 is in an area with a faster wear rate. In this way, after the positions of the lower wear-resistant plate 9 and the upper wear-resistant plate 10 are swapped, the overall degree of wear of the two is roughly the same. In conjunction with the moving device 7 that can drive the lower wear-resistant plate 9 and the upper wear-resistant plate 10 to move, the lower wear-resistant plate 9 and the upper wear-resistant plate 10 can maintain synchronous wear, so that the inner plate 5 as a whole can be used for a longer time before replacement, which can extend the service life of the inner plate 5.

[0059] It should be noted that, in order to keep the lower wear-resistant plate 9 and the upper wear-resistant plate 10 stable during the up and down movement, a guide block 1001 is provided in the upper wear-resistant plate 10, and a guide groove 1111 is provided in the replacement unit 11, and the guide block 1001 cooperates with the guide groove 1111;

[0060] A guide plate 1108 is provided on the inner frame 1102 , the guide plate 1108 is connected to a slider 1109 , the slider 1109 is plugged with a guide rail 1110 , the guide rail 1110 is connected to an outer frame, and a guide groove 1111 is provided inside the outer frame.

[0061] Working principle:

[0062] The side detection module 803 may be an electromagnetic ultrasonic detection sensor, which is arranged in the side detector mounting groove 802. A plurality of electromagnetic ultrasonic detection sensors can measure the wall thickness at a plurality of points of the wear-resistant side plate 801, and judge the wear condition of the wear-resistant side plate 801 according to the measured data. If the wear exceeds the set value, the wear-resistant side plate 801 can be pushed to move to the side close to the outer wall of the roller 1 by the side detection feeding unit 8, so as to shorten the distance between the wear-resistant side plate 801 and the outer wall of the roller 1. At this time, the worn wear-resistant side plate 801 can still block the materials in the working area.

[0063] When the front wall thickness detection module 12 measures that the thickness of the lower wear-resistant plate 9 is less than a certain value of the thickness of the upper wear-resistant plate 10, the replacement unit 11 is started, and the retraction power unit 1107 is started, so that the lower wear-resistant plate 9 is converted to a retracted state, and then the winding device 1101 is started, and the connecting rope on it pulls the lower wear-resistant plate 9 up, and the other end of the connecting rope is loosened, and the upper wear-resistant plate 10 moves down under the action of gravity, and finally the upper wear-resistant plate 10 falls to the position of the original lower wear-resistant plate 9, and then the retraction power unit 1107 is started, so that the lower wear-resistant plate 9 Converted to the expanded state, the positions of the lower wear-resistant plate 9 and the upper wear-resistant plate 10 are swapped. At this time, the upper wear-resistant plate 10 is in an area with faster wear speed. In this way, after the positions of the lower wear-resistant plate 9 and the upper wear-resistant plate 10 are swapped, the overall wear degree of the two is roughly the same. With the moving device 7 that can drive the lower wear-resistant plate 9 and the upper wear-resistant plate 10 to move, the lower wear-resistant plate 9 and the upper wear-resistant plate 10 can maintain synchronous wear, so that the inner plate 5 as a whole can be used for a longer time before replacement, which can extend the service life of the inner plate 5.
