Description

Technical Field

[0001] This utility model belongs to the technical field of high gradient pulsating vertical ring magnetic separator, and in particular relates to a high gradient pulsating vertical ring magnetic separator with a snap ring sound and light automatic alarm device. Background Technology

[0002] In the grinding and beneficiation area of ​​the ore processing plant, the currently used SLON high-gradient pulsating vertical ring magnetic separator frequently experiences ring jamming during actual production due to various reasons (such as loose or fallen magnetic media box fastening screws, warped magnetic stainless steel rods inside the magnetic media box, excessive feed load on the magnetic separator, impurities in the feed, excessive content of strongly magnetic minerals in the feed, and electrical and mechanical issues). When ring jamming occurs during normal operation of the magnetic separator, the rotating ring is stuck and cannot rotate, while the ring drive motor continues to operate. If the personnel do not detect and address this issue promptly, allowing the jamming to continue, it will cause a significant amount of ore to escape from the magnetic separator. Serious problems such as crushing the sorting box, burning out the V-belt, stalling the rotating drive motor, damaging the reducer due to excessive load, and scratching the magnetic media box not only increase the labor intensity of the guards and maintenance personnel, but also cause huge economic losses to the company. If the stuck ring is caused by the loose or fallen fastening screws of the magnetic media box, it is necessary to shut down the machine for a long time for maintenance, lift the rotating ring, remove the screws that have fallen into the gap between the iron blades under the magnetic separator, and replace the magnetic media box that was scratched by the fastening screws. The maintenance time is generally 2 days, which not only increases the load on other magnetic separation equipment, but also makes the production indicators unstable. Summary of the Invention

[0003] The purpose of this utility model is to provide a SLON high gradient pulsating vertical ring magnetic separator with an automatic sound and light alarm device for ring jamming. This solves the problem of large amounts of ore being lost at the work site, damage to the magnetic separation equipment, or damage to the magnetic medium box caused by the failure of on-site personnel to promptly detect and handle the situation when the rotating ring stops or jams during normal operation of the SLON high gradient pulsating vertical ring magnetic separator. This also prevents the equipment accident from escalating.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] The present invention relates to a high-gradient pulsating vertical ring magnetic separator with a retaining ring and an automatic sound and light alarm device, characterized in that it includes a circular induction magnet adsorbed on the main shaft of the magnetic separator's rotating ring, a sensor whose working surface is opposite to the working surface of the circular induction magnet, a monitoring and alarm controller connected to the sensor, and an automatic sound and light alarm lamp connected to the monitoring and alarm controller.

[0006] The diameter of the circular induction magnet is 7mm.

[0007] The circular induction magnets consist of eight pieces, arranged in a star-shaped circular pattern and adsorbed onto the main shaft of the magnetic separator's rotating ring.

[0008] The working gap between the sensor and the circular induction magnet is within 10mm.

[0009] Advantages of this utility model:

[0010] This utility model relates to a high-gradient pulsating vertical ring magnetic separator with an automatic audible and visual alarm device for ring jamming. When the rotating ring of the SLON high-gradient pulsating vertical ring magnetic separator is installed on the rotating main shaft, the device, connected to the main shaft, rotates simultaneously. If the rotating ring stops or jams for any reason, the automatic audible and visual alarm device on the main shaft will issue an alarm signal within 4 seconds, prompting personnel to handle the situation immediately and preventing the equipment accident from escalating. This device effectively monitors the operation of reciprocating rotating equipment, replacing manual monitoring and reducing the risk of ore spillage and equipment or magnetic media box damage caused by the failure to detect jamming or abnormalities in a timely manner. It significantly reduces the workload of personnel and maintenance staff. The installation and application of this device are innovative, practical, and novel, reducing equipment failure rates and economic losses for enterprises, making a significant contribution to cost reduction and efficiency improvement in concentrators. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0012] The specific embodiments of this utility model are further described below with reference to the accompanying drawings.

[0013] like Figure 1 As shown, the high-gradient pulsating vertical ring magnetic separator with a snap ring sound and light automatic alarm device of this utility model is characterized by including a circular induction magnet 1 adsorbed on the main shaft 3 of the magnetic separator rotating ring, a sensor 2 whose working surface is opposite to the working surface of the circular induction magnet 1, a monitoring and alarm controller 4 connected to the sensor 2, and a sound and light automatic alarm lamp 5 connected to the monitoring and alarm controller 4.

[0014] The circular induction magnet 1 has a diameter of 7mm.

[0015] The circular induction magnets 1 consist of eight pieces, which are arranged in a star-shaped circular pattern and adsorbed onto the main shaft 3 of the magnetic separator rotating ring.

[0016] The working gap between the sensor 2 and the circular induction magnet 1 is within 10mm.

[0017] The following describes the specific implementation of the present invention with reference to the accompanying drawings. The magnetic separator's rotating ring is connected to the main shaft, and they rotate simultaneously. First, a circular induction magnet 1 with a diameter of 7 mm is attached to the main shaft 3 of the rotating ring. Eight circular induction magnets 1 are attached to the main shaft 3 of the rotating ring in a star-shaped arrangement, with equal spacing between each circular induction magnet 1. The monitoring and alarm controller 4 is installed near the magnetic separator. The monitoring and alarm controller 4 is wired and installed to the sensor 2 and waterproofed. The sensor 2 bracket is then fixed to the bearing seat of the main shaft. The sensor 2 is positioned facing the working surface of the circular induction magnet 1, with a working gap of less than 10 mm between the sensor 2 and the circular induction magnet 1. Then, the audible and visual automatic alarm light 5 is installed in the operator's room. The audible and visual automatic alarm light 5 is wirelessly connected to the monitoring and alarm controller 4, with an effective distance of up to 4.7 kilometers. The audible and visual automatic alarm light 5 can also be wired to the monitoring and alarm controller 4. The installation of the ring-mounted audible and visual automatic alarm device is now complete.

[0018] This invention relates to a high-gradient pulsating vertical ring magnetic separator with an automatic audible and visual alarm device for ring jamming. After installing the device on the rotating main shaft 3 of the SLON high-gradient pulsating vertical ring magnetic separator, the rotating ring and main shaft 3 rotate simultaneously. When the magnetic separator stops rotating or jams due to various reasons, the automatic audible and visual alarm device on the main shaft 3 will emit an audible and visual alarm signal within 4 seconds, prompting the personnel at the magnetic separator to handle the situation immediately and prevent the equipment accident from escalating. This device has a good monitoring function for the operation of reciprocating rotating equipment, and can replace on-site personnel for real-time monitoring of the equipment. It reduces the occurrence of large-scale ore leakage and equipment or magnetic medium box damage caused by the failure to detect equipment jamming or abnormalities in a timely manner, greatly reducing the labor intensity of on-site and maintenance personnel. The installation and application of this device is innovative, practical, and novel, reducing the equipment failure rate, reducing the economic losses of enterprises, and making a significant contribution to cost reduction and efficiency improvement in concentrators.
