Description

Technical Field

[0001] This utility model relates to the field of vibrating screen motor technology, and in particular to a vibrating screen side plate motor with temperature monitoring function. Background Technology

[0002] Vibrating screens, widely used in the market, are primarily employed in material screening processes to achieve efficient and precise material grading. Traditional vibrating screen designs rely on motors and traction devices to drive their vibration, enabling materials to be thrown upwards, tumbled, and rapidly graded by gravity. However, during prolonged operation, the motors and their connected components, especially those located on the side plates of the vibrating screen, can overheat due to the complexity of the working environment, such as temperature variations and vibration impacts. This directly affects the stability and lifespan of the equipment.

[0003] Existing technologies often monitor motor temperature by installing a set of temperature sensors on the motor. However, this only provides a general indication of the motor's operating temperature and cannot monitor the specific operating temperature of the motor components on the vibrating screen side plate. In cases where the vibrating screen motor experiences performance degradation or even malfunction due to overheating, relying solely on a single set of temperature sensors is unreliable and cannot provide a timely and effective overheat protection mechanism. This fails to guarantee the safety and stability of the equipment during operation, and it also makes it difficult to pinpoint the location of the overheating when the motor is overheating, hindering motor upgrades and improvements.

[0004] Therefore, this application provides a vibrating screen side plate motor with temperature monitoring function to meet the requirements. Utility Model Content

[0005] The purpose of this application is to provide a vibrating screen side plate motor with temperature monitoring function. By building multiple sets of temperature sensors, the temperature status of the stator and bearings of the motor can be monitored in real time during operation. This can effectively evaluate the thermal management of the motor during operation, significantly improve the reliability and safety of the vibrating screen, and facilitate the improvement and upgrading of the motor.

[0006] To achieve the above objectives, this application provides the following technical solution: a vibrating screen side plate motor with temperature monitoring function, comprising:

The partition plate has a through hole for the rotating shaft to pass through. The partition plate separates the space where the front bearing and the stator are located. A bearing temperature sensor is provided on the front side of the partition plate and a stator temperature sensor is provided on the rear side of the partition plate.

The stator temperature sensor is used to monitor the temperature of the stator, and the end of the stator temperature sensor is close to the stator.

[0013] Preferably, the rear side of the temperature measuring plate is provided with a ring sleeve, the ring sleeve is matched with the size of the outer shell, the inner circumference of the ring sleeve is provided with a ring seat, the separator plate is rotatably connected in the ring seat, and the front side of the separator plate is provided with a limiting ring, the limiting ring limits the separator plate from the front side.

The front cover 2 is installed at the front end of the housing 1, and the rear cover 3 is installed at the rear end of the housing 1. Both the front cover 2 and the rear cover 3 are provided with bearings for installing the rotor shaft.

[0029] The temperature measuring plate 4 is installed between the front cover 2 and the outer shell 1. The middle part of the temperature measuring plate 4 is provided with a partition plate 5. The partition plate 5 is provided with a through hole for the rotating shaft to pass through. The partition plate 5 separates the space where the front bearing and the stator 10 are located. The front side of the partition plate 5 is provided with a bearing temperature sensor 7, and the rear side of the partition plate 5 is provided with a stator temperature sensor 8.

[0030] The bearing temperature sensor 7 is used to monitor the temperature of the bearing, and its end is close to the front bearing. The stator temperature sensor 8 is used to monitor the temperature of the stator 10, and its end is close to the stator 10.

[0031] As one implementation method in this embodiment, to make the temperature measurement effect more flexible, such as Figure 2 As shown, a ring 40 is provided on the rear side of the temperature measuring plate 4. The ring 40 matches the size of the outer shell 1. A ring seat 41 is provided on the inner circumference of the ring 40. The separator plate 5 is rotatably connected in the ring seat 41. A limiting ring 6 is provided on the front side of the separator plate 5. The limiting ring 6 limits the separator plate 5 from the front side.

[0032] As one implementation method in this embodiment, to buffer and limit the rotation of the separator 5, such as... Figure 4 As shown, the lower part of the limiting ring 6 is symmetrically provided with columns, and the front side of the temperature measuring plate 4 is symmetrically provided with fixed columns. A tension spring 9 is connected between the corresponding columns and the fixed columns.

[0033] As one implementation method in this embodiment, to facilitate the installation of the bearing temperature sensor 7, such as Figure 3 , Figure 4 As shown, mounting seats 50 are symmetrically provided on the front side of the partition plate 5. Each set of mounting seats 50 is connected to a pressure plate by bolts. A bearing temperature sensor 7 is installed between the mounting seat 50 and the pressure plate.

[0034] As one implementation method in this embodiment, to facilitate the installation of the stator temperature sensor 8, such as Figure 3 , Figure 4 As shown, the separator plate 5 is symmetrically provided with through holes, the limiting ring 6 is symmetrically provided with screw holes, and the stator temperature sensor 8 is threaded into the screw hole and passes through the through hole.

[0035] As one implementation method in this embodiment, to facilitate fixing the rear end cover 3 to the vibrating screen, such as...

[0037] The working principle of this utility model is as follows: When installing the motor, the motor is lifted using the lifting ring 11 on the outer casing 1. The motor is then fixed to the side plate of the vibrating screen using the fixing ring 30 on the outer periphery of the rear end cover 3. When the vibrating screen is working, the motor starts, driving the exciter to vibrate. The partition plate 5 separates the space where the stator 10 and the bearing on the front end cover 2 are located, allowing the bearing temperature sensor 7 and the stator temperature sensor 8 to monitor the temperature of the bearing and stator 10 respectively, reducing mutual interference. Due to vibration, the combination of the partition plate 5 and the limiting ring 6 rotates in the ring seat 41. The tension spring 9 extends and retracts the former's rotation, buffering and limiting the rotation, causing the combination of the partition plate 5 and the limiting ring 6 to rotate back and forth. During this process, the bearing temperature sensor 7 and the stator temperature sensor 8 rotate accordingly, expanding the temperature measurement range and realizing multi-point, large-area temperature monitoring, making temperature monitoring more reliable. The ring 40 facilitates the installation of the temperature measuring plate 4 on the front end of the outer casing 1.
