Description

Technical Field

[0001] This utility model belongs to the field of vibrating screening technology, specifically relating to an intelligent screen plate mounted on a rail base. Background Technology

[0002] A vibrating screen is a mechanical device used for screening, grading, dewatering, desliming, or demediuming granular, powdery, or small lump materials. It primarily uses a vibrating motor or other excitation device to generate vibration, causing the material on the screen plate to move in a regular pattern, thereby achieving the purpose of separating materials of different particle sizes or properties. When the vibrating screen is working, the vibration generated by the exciter drives the screen box and the screen plates installed inside the screen box to vibrate. Material enters the screen surface through the feed inlet, and under the action of vibration, the material jumps and slides on the screen surface. Material smaller than the screen aperture size falls through the screen holes and is collected as undersize; material larger than the screen aperture size moves along the screen surface and is discharged from the other end of the screen box as oversize.

[0003] During the screening process, the screen plates are considered wear parts of vibrating screens and require frequent replacement. Currently, rail-mounted structures are commonly used in coal preparation plants for easy installation and disassembly, but they are prone to detachment. Detached screen plates not only directly affect the screening efficiency of the vibrating screen but can also cause abnormal shutdowns or even damage to downstream equipment. Since there are many vibrating screens in a coal preparation plant, and each screen has a large number of screen plates, the inspection of these plates is particularly important. However, manual inspection is not only labor-intensive but also inefficient, especially for multi-layer screens, where manual inspection cannot effectively check for detached screen plates on the second or third layers. Utility Model Content

[0004] Based on the technical problems existing in the prior art, this utility model provides a smart screen plate mounted on a rail base, which integrates the sensor with the rail base and the sensor with the screen plate into one unit to form a smart screen plate. The built-in sensor can monitor the changes in the relative position between the screen plate and the rail base in real time, solving the problems of low efficiency and the need for manual inspection in the prior art.

[0005] According to the technical solution of this utility model, this utility model provides a smart sieve plate mounted on a rail base, which includes a sieve plate, a rail base, a sensor, and a sensing element;

[0006] Screen plates are used for grading and sorting materials. Screen plates have screen holes of a specific size. Materials smaller than the screen hole size pass through the screen hole and become the undersize, while materials larger than the screen hole size cannot pass through the screen hole and become the oversize, thus achieving the purpose of grading and sorting.

[0007] The rail base is used to support and fix the screen plate. The rail base is a polyurethane casting structure with steel inserts inside the polyurethane.

[0008] The sensor is used to detect whether the sieve plate is installed in place or whether it is loose. It is embedded in the rail base and is integrally formed with the rail base. The change in the signal received by the sensor reflects the change in the distance between the sensor and the sensing element.

[0009] The sensing element is embedded in the polyurethane edging on both sides of the screen plate. When the screen plate is not installed properly or becomes loose, the sensor signal changes beyond the design threshold, indicating that the screen plate is abnormal.

[0010] Preferably, the sensor and the rail base are integrated into one unit. The sieve plate is polyurethane-coated, and the sensing element is integrated with the sieve plate.

[0011] Preferably, the rail base is equipped with a latch; when installing the screen plate, the screen plate slot is pressed into the latch of the rail base. The sensor uses wired signal transmission or wireless communication.

[0012] Preferably, the screen plate and the rail base adopt a press-in and pry-out design. The screen plate is installed on the rail base, and two screen plates are installed on each rail base. Each screen plate has an embedded sensing element.

[0013] Preferably, after the screen plate and the rail base are installed in place, the sensing element is directly above the sensor. The sensor monitors the sensing element, and the strength of the signal is related to the distance between the sensor and the sensing element. The change in position between the screen plate and the rail base is determined based on the strength of the signal.

[0014] Furthermore, the sensor and the track are integrally molded using polyurethane casting. The sensing element and the screen plate are also integrally molded using polyurethane casting.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] It should also be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0027] It should be noted that the concepts of "first" and "second" mentioned in this utility model are only used to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units or their interdependencies.

[0028] It should be noted that the terms "a" and "a plurality of" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0029] This utility model discloses a rail-mounted intelligent sieve plate, comprising a sieve plate, a rail base, a sensor, and a sensing element. The sieve plate is used for material grading and sorting; the rail base supports and fixes the sieve plate; the sensor detects whether the sieve plate is properly installed or loose; the sensing element is embedded in the polyurethane edging on both sides of the sieve plate. When the sieve plate is not properly installed or becomes loose, the sensor signal change exceeds the design threshold, indicating a sieve plate malfunction. Based on existing technology, this utility model integrates the sensor, rail base, and sieve plate into a single intelligent sieve plate. Through the built-in sensor, this utility model can monitor the relative position changes between the sieve plate and the rail base in real time. When the sieve plate becomes loose, it can issue an early warning to the central control system and accurately locate the loose position for proactive handling, solving the problems of manual inspection and low efficiency in existing technologies.

[0030] like Figures 1-2 As shown, this utility model provides a smart sieve plate mounted on a rail base, which includes a sieve plate 1, a rail base 2, a sensor 3, and a sensing element 4.

[0031] Screen plate 1 is used for material grading and sorting. It has screen holes of a specific size. Materials smaller than the screen hole size pass through and become undersize, while materials larger than the screen hole size cannot pass through and become oversize, thus achieving the purpose of grading and sorting. Screen plate 1 has a polyurethane-lined structure, and its dimensions are standardized, with specifications of 610mm×610mm and 610mm×305mm. The polyurethane edging on both sides of the screen plate has grooves for mounting and fixing the screen plate to the rail base.

[0032] The sensing element 4 is integrated with the screen plate 1; the screen plate 1 is the core component for material screening, and its main functions include screening and grading materials. The vibrating screen operates using the reciprocating vibration generated by the standard excitation of the vibrator. The screen plate 1 has screen holes of different sizes. When the vibrating screen is working, the vibration generated by the vibrator drives the screen box and the screen plate installed inside the screen box to vibrate. The material enters the screen surface from the feed inlet, and under the action of vibration, the material jumps and slides on the screen surface. Material smaller than the screen hole size falls through the screen holes and is collected as undersize; material larger than the screen hole size moves along the screen surface and is discharged from the other end of the screen box as oversize.

[0033] The rail base 2 is used to support and fix the screen plate 1. The rail base 2 is a polyurethane casting structure with steel inserts inside the polyurethane. The polyurethane rail base has clips; during screen plate installation, the screen plate 1 is pressed into the clips of the rail base 2 to fix the screen plate 1. The rail base 2 is a polyurethane-coated component, possessing high strength, wear resistance, and corrosion resistance. The sensor 3 is integrated with the rail base 2. The rail base 2 supports the screen plate 1, preventing it from being subjected to friction and wear from the material, thereby extending the service life of the screen plate 1 and improving screening efficiency and quality.

[0034] Sensor 3 is used to detect whether the screen plate is installed in place or whether it is loose. Sensor 3 is embedded in the rail base 2 and is integrally formed with the rail base 2. Sensor 3 is used in conjunction with sensing element 4. When the distance between sensing element 4 and sensor 3 is within a certain range, a sensing signal will be generated inside sensor 3. The change in the sensing signal reflects the change in the distance between sensor 3 and sensing element 4.

[0035] Sensor 3 can use wired signal transmission or wireless communication. When using wired signal transmission, the power supply cable and signal cable of sensor 3 pass through the cable tray inside the rail base, and all sensor cables are connected in series.

[0036] The sensing element 4 is embedded in the polyurethane edging on both sides of the sieve plate 1 and is integrally formed with the sieve plate 1 by polyurethane casting. The sensing element 4 is usually a magnetic element. When the sieve plate 1 is not installed properly, or the sieve plate 1 becomes loose, or the distance between the sensing element 4 and the sensor 3 is within a certain range, the sensor 3 will generate a sensing signal. If the change in the sensor 3 signal exceeds the design threshold, it can be determined that the sieve plate 1 is abnormal.

[0037] like Figure 1 and Figure 2 As shown, a smart sieve plate mounted on a rail base includes a sieve plate 1, a rail base 2, a sensor 3, and a sensing element 4. The sensor 3 is integrated with the rail base 2, and the sensing element 4 is integrated with the sieve plate 1. The sieve plate 1 and the rail base 2 adopt a press-in and pry-out design. The sieve plate 1 is installed above the rail base 2, and two sieve plates 1 are installed on each rail base 2. Each sieve plate 1 has an embedded sensing element 4. The sensing element 4 is embedded in the sieve plate 1 and integrally molded by polyurethane casting. The sensor 3 is embedded in the rail base 2 and integrally molded by polyurethane casting. After the sieve plate 1 and the rail base 2 are installed in place, the sensing element 4 is directly above the sensor 3. The sensor 3 monitors the sensing element 4, and the strength of the signal is related to the distance between the sensor and the sensing element 4. The change in position between the sieve plate 1 and the rail base 2 is determined based on the signal strength.

[0038] In this embodiment, during installation, the screen plate 1 and the rail base 2 are first connected to the dedicated rail base via a single-sided hook, and the dedicated rail base is then connected to the supporting angle steel of the screen plate 1 via countersunk screws. This design solves the problem of difficult disassembly of the screen plate 1 and prevents the screen plate 1 from falling off during vibration, thereby saving maintenance time and reducing maintenance costs. Next, the sensing element 4 is embedded inside the screen plate 1. Finally, the sensor 3 is installed on the rail base 2, with the sensor 3 directly below the sensing element 4.

[0039] This utility model is based on a rail-mounted structure, which has strong versatility and interchangeability. It can monitor whether the screen plate is initially installed correctly. If the screen plate is not installed correctly, it can issue an alarm and accurately locate the alarm position. It can monitor the positional changes between the screen plate and the rail in real time. When the change exceeds the threshold, it can issue an alarm and accurately locate the alarm position to prevent the screen plate from falling off and causing serious losses. It replaces manual inspection, which is more efficient and accurate.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
