Description

Technical Field

[0001] This utility model relates to the field of steel plate processing technology, and in particular to a corrosion-resistant monitoring and protection device for the oil level of a sintering plant reducer. Background Technology

[0002] With technological advancements, remote operation of sintering plant equipment has become a trend. Retrofitting existing equipment for remote operation requires adding numerous remote sensors to transmit various equipment information to the backend for maintenance and operation personnel. The reducer, as one of the most critical components in sintering plant equipment, normally uses an oil bath for lubrication of its bearings and gears. The oil temperature and level in the oil bath are parameters of utmost concern to maintenance personnel. High oil temperature indicates problems with reducer operation and potential bearing and gear failures; low oil level affects the lubrication of the reducer's bearings and gears. Practice has shown that timely cleaning and oil changes based on changes in oil temperature and level in the oil bath are crucial for extending the reducer's service life.

[0003] However, existing speed reducers generally only use visual oil sight glasses or dipsticks, which require operators to visually inspect the oil. They cannot transmit data to the back-end speed reducer main control system, resulting in low automation efficiency. Moreover, when the lubricating oil temperature in the speed reducer exceeds the preset value, it is inconvenient to dissipate heat from the lubricating oil, affecting the performance of the speed reducer. These issues need to be improved.

[0004] Therefore, this utility model provides a corrosion-resistant monitoring and protection device for the oil level of a sintering plant reducer to solve the problems in the background art. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1-5 A corrosion-resistant monitoring and protection device for the oil level of a sintering plant reducer includes: a gearbox 1, a heat dissipation mechanism 4, and a monitoring mechanism 5;

[0023] A housing 2 is fixedly connected to one side of the gearbox 1, and a round tube 3 is fixedly installed on one side of the housing 2. The heat dissipation mechanism is set inside the housing 2 and the round tube 3 and connected to the gearbox 1. The gearbox 1 has an installation hole, and a monitoring mechanism 5 is installed in the installation hole.

[0024] The heat dissipation mechanism 4 includes a liquid pump 41, a three-way pipe 42, a heat dissipation pipe 43, a heat dissipation fan 44, a delivery pipe 45, a solenoid valve 46, and a solenoid valve 47. The liquid pump 41 is fixedly installed inside the housing 2, and one end of the liquid pump 41 is sealed to the gearbox 1. The heat dissipation fan 44 is fixedly installed inside the round pipe 3, and multiple dustproof nets are installed at one end of the round pipe 3. Through the coordinated design between the gearbox 1, the monitoring mechanism 5, and the heat dissipation mechanism 4, the lubricating oil in the gearbox 1 can be automatically monitored, and the lubricating oil can also be automatically cooled. The liquid pump 41 and the heat dissipation fan 44 are connected to the main control module of the downstream gearbox via electrical connection.

[0025] In this method, one end of the liquid pump 41 is sealed to a three-way pipe 42, and one end of the three-way pipe 42 is sealed to a heat dissipation pipe 43. One end of the heat dissipation pipe 43 is sealed to the gearbox 1. Through the function of the heat dissipation pipe 43, heat transfer with the lubricating oil can be achieved, thereby facilitating the cooling of the lubricating oil.

[0026] In this method, the heat dissipation pipe 43 corresponds to the heat dissipation fan 44, and one end of the tee pipe 42 is sealed and connected to the delivery pipe 45. One end of the delivery pipe 45 passes through the housing 2. Through the action of the heat dissipation fan 44, the air flows rapidly in the housing 2, thereby achieving the effect of heat transfer between the air and the heat dissipation pipe 43, and thus achieving the effect of heat dissipation and cooling of the lubricating oil.

[0027] In this method, a mounting groove 6 is provided on one side of the housing 2. A dustproof net is fixedly installed in the mounting groove. The mounting groove 6 corresponds to the heat dissipation pipe 43 and the heat dissipation fan 44 to facilitate air circulation. A solenoid valve 46 is provided on the delivery pipe 45, and a solenoid valve 47 is provided on the heat dissipation pipe 43 to facilitate remote control of the opening and closing of the heat dissipation pipe 43 and the delivery pipe 45, thereby improving automation efficiency.

[0028] In this method, the monitoring mechanism includes a fixed base 51, a liquid level sensor 52, a protective tube 53, a temperature sensor 54, and a wire 55. The fixed base 51 is threaded into the mounting hole, and the liquid level sensor 52 is fixedly installed on the fixed base 51. The liquid level sensor 52 extends into the gearbox 1, and a protective tube 53 is fitted onto the liquid level sensor 52. One end of the protective tube 53 is fixedly connected to the fixed base 51 and is compatible with the fixed base 51. The temperature sensor 54 is fixedly installed on one end of the protective tube 53. The temperature sensor 54 can detect the temperature of the lubricating oil in the gearbox 1 and transmit the detected information to the back-end gearbox main control module through the wire 55. The liquid level sensor 52 can detect the oil level in the gearbox 1 and transmit the detected information to the back-end gearbox main control module. At this time, the back-end gearbox main control module analyzes the received information and controls and drives the liquid pump 41 and the cooling fan 44 according to the analysis results.

[0029] In this method, a wire 55 is fixedly installed on the mounting base 51. The wire 55 is connected to the liquid level sensor 52 and the temperature sensor 54. One end of the wire 55 is connected to the main control module of the rear reducer. Both the temperature sensor 54 and the liquid level sensor 52 are provided with a corrosion-resistant layer, which is a nickel alloy.

[0030] In this method, the gearbox 1 contains lubricating oil, and a partition 7 is fixedly installed inside the gearbox 1. The partition 7 is located above the inlet end of the liquid pump 41. One end of the partition 7 has a through hole 8. During the process of the liquid pump 41 drawing lubricating oil below the partition 7, the uncooled lubricating oil in the gearbox 1 will flow through the through hole 8 through the guide of the partition 7 to the bottom of the partition 7, thereby achieving the effect of circulating the lubricating oil and facilitating the circulation and heat dissipation of the lubricating oil.

[0031] The working principle of the corrosion-resistant oil level monitoring and protection device for a sintering plant reducer provided by this utility model is as follows:

[0032] In use, the hydraulic pump 41 and the cooling fan 44 are driven and controlled by the back-end reducer main control module. The temperature sensor 54 can detect the temperature of the lubricating oil in the gearbox 1 and transmit the detected information to the back-end reducer main control module through the wire 55. The level sensor 52 can detect the oil level in the gearbox 1 and transmit the detected information to the back-end reducer main control module. At this time, the back-end reducer main control module analyzes the received information and controls and drives the hydraulic pump 41 and the cooling fan 44 according to the analysis results.

[0033] When it is necessary to cool the lubricating oil in the gearbox 1, the lubricating oil under the partition 7 is drawn out by the hydraulic pump 41 and the solenoid valve 47 is opened and transported to the heat dissipation pipe 43 through the three-way pipe 42, so that the lubricating oil and the heat dissipation pipe 43 can transfer heat. At the same time, the air is made to flow rapidly in the housing 2 by the cooling fan 44, so that the air and the heat dissipation pipe 43 can transfer heat, thereby achieving the effect of cooling the lubricating oil.

[0034] Afterwards, the cooled lubricating oil is discharged to the top of the gearbox 1 through the other end of the heat dissipation pipe 43. During this process, the uncooled lubricating oil in the gearbox 1 will flow through the through hole 8 through the guide of the partition 7 to the bottom of the partition 7, thereby achieving the effect of circulating the lubricating oil and facilitating the circulation and heat dissipation of the lubricating oil.

[0035] Driven by the hydraulic pump 41, the solenoid valve 46 is opened, thereby drawing out the lubricating oil in the gearbox 1 and discharging it through the delivery pipe 45, thus achieving the effect of automatically drawing out the lubricating oil and facilitating the replacement of the lubricating oil in the gearbox 1.

[0036] Compared with related technologies, the corrosion-resistant monitoring and protection device for the oil level of a sintering plant reducer provided by this utility model has the following beneficial effects: through the cooperation of various components, the lubricating oil in the reducer 1 can be automatically monitored, which improves convenience. It can also achieve the effect of automatic heat dissipation of the lubricating oil. Moreover, the structure is simple and the practicality is higher.
