Technical Field

[0001] This utility model relates to the field of red mud filter press production, and in particular to an automatic track refueling device. Background Technology

[0002] Red mud filter press production is an important byproduct preparation process in bauxite (aluminum ore) refining. It mainly involves the extraction of aluminum oxides from bauxite after crushing, grinding, and calcination. The processed bauxite often contains a large amount of waste material, namely red mud. The treatment of red mud is crucial, and many bauxite companies use filter presses for dewatering to reduce its moisture content and volume, making it easier to store and handle. The working principle of a filter press relies on filter plates and filter cloth using high pressure to separate the liquid from the slurry, thus achieving a highly efficient dewatering process.

[0003] In the process of developing this application, the inventors discovered the following problems with the existing technology: Traditional track lubrication methods rely on manual periodic oiling, which has many problems, such as low efficiency of manual oiling, and improper operation may lead to over-oiling or leakage, thereby affecting the operation of the equipment. Due to dripping of lubricating oil, excessive use, or inadequate lubrication, equipment failure, environmental pollution, or even safety accidents may occur.

[0004] Therefore, those skilled in the art have provided an automatic rail refueling device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic track lubrication device. This invention can automatically identify the activity state of the filter plates and perform precise lubrication at the correct time, avoiding manual intervention, improving lubrication efficiency, ensuring a clean and safe production environment, and possessing high efficiency and energy-saving characteristics.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automatic rail refueling device includes a filter press, a lubricating oil storage tank, and a system control box. Rails are fixedly installed on both the front and rear sides of the upper end of the filter press, and filter plates are movably installed between each pair of rails. Cables are installed on the outside of the system control box, and multiple photoelectric sensors are installed at the cable connection points. A refueling pump is fixedly installed at the upper end of the lubricating oil reservoir, and a pressure sensor is fixedly installed at the output end of the refueling pump. An oil outlet is fixedly installed on the other side of the upper end of the lubricating oil reservoir, and a pipe is fixedly installed at the output end of the oil outlet. A refueling nozzle is installed at the output end of multiple connections at the outer end of the pipe, and a solenoid valve is fixedly installed near the refueling nozzle on the pipe.

[0007] Furthermore, an ultrasonic level gauge is installed on the upper rear side of the lubricating oil reservoir.

[0008] Furthermore, the plurality of photoelectric sensors are electrically connected to the system control box, and the plurality of photoelectric sensors are electrically connected to the solenoid valve.

[0009] Furthermore, the filter press is electrically connected to the operating status sensor, and the oil pump is electrically connected to the operating status sensor.

[0010] Furthermore, the lubricating oil reservoir is electrically connected to the system control box, and an oil tank temperature sensor is installed at the outer end of the lubricating oil reservoir.

[0011] Furthermore, a universal telescopic pipe is fixedly installed between the pipeline and the refueling nozzle.

[0012] Furthermore, a fixing ring is fixedly sleeved on the outer end of the pipe, and an adjusting rod is connected to the front end of the fixing ring by bolt hinge. A telescopic rod is fixedly installed between the refueling nozzle and the adjusting rod. Compared with the prior art, the beneficial effects of this utility model are: This invention proposes an automatic lubrication device for the track. A working status sensor monitors the operating status of the filter press. When the filter press is ready to unload, the sensor sends a signal to start the lubrication pump. Then, a photoelectric sensor detects that the filter plates have opened and formed a sufficient gap. The system control box controls the lubrication process via a solenoid valve. The lubricating oil is precisely sprayed onto the track surface through a lubrication nozzle, ensuring smooth track operation. The touchscreen displays the liquid level, oil temperature, oil pressure, and the status of the lubrication pump and valves in real time. This significantly improves the lubrication efficiency of the red mud filter press track, avoids operational errors and safety hazards caused by manual lubrication, and ensures the stability and efficiency of the equipment. Furthermore, the device's automatic control and energy-saving features effectively reduce lubricating oil waste, decrease maintenance costs, and improve equipment operating efficiency. Through intelligent monitoring and automatic alarm functions, the system can also ensure timely replenishment of lubricating oil when needed, thereby extending the equipment's service life and reducing downtime.

An oil refueling pump 205 is fixedly installed on the upper end of the lubricating oil storage tank 2, and a pressure sensor 206 is fixedly installed at the output end of the oil refueling pump 205. An oil outlet 201 is fixedly installed on the other side of the upper end of the lubricating oil storage tank 2, and a pipe 202 is fixedly installed at the output end of the oil outlet 201. Multiple connection points on the outer end of the pipe 202 are equipped with refueling nozzles 203, and solenoid valves are fixedly installed near the refueling nozzles 203 on the pipe 202. 204. An ultrasonic level gauge is installed on the rear side of the upper end of the lubricating oil storage tank 2. Multiple photoelectric sensors 302 are electrically connected to the system control box 3. Multiple photoelectric sensors 302 are electrically connected to the solenoid valve 204. The filter press 1 is electrically connected to the working status sensor. The oil pump 205 is electrically connected to the working status sensor. The lubricating oil storage tank 2 is electrically connected to the system control box 3. An oil tank temperature sensor is installed at the outer end of the lubricating oil storage tank 2. A metal universal telescopic pipe 20301 is fixedly installed between the pipe 202 and the oil nozzle 203. A fixing ring 20302 is fixedly sleeved on the outer end of the pipe 202. An adjusting rod 20303 is connected to the front end of the fixing ring 20302 by bolt hinge. A telescopic rod 20304 is fixedly installed between the oil nozzle 203 and the adjusting rod 20303.

[0020] Specifically, such as Figure 1The photoelectric sensor 302 is located at the connection point of cable 301. During system operation, the working status sensor is connected to the plate-pulling trolley. The plate-pulling trolley is a prior art technology, built into the filter press 1, and is installed on both sides of the filter plate 102 to pull the filter plate 102 apart. Specifically, the plate-pulling trolley is installed on the tracks 101 on both sides of the filter plate 102 of the filter press 1, and is usually composed of a drive device, a mechanical gripper or hook. Its function is to grab and move the filter plate 102 one by one according to the program instructions, so as to realize the separation and resetting of the filter plate 102. After the filter press 1 completes the filtration of red mud, the filter plates 102 are tightly arranged, and the red mud is stored in the filter chamber. The hydraulic system releases the clamping plate to make room for the plate-pulling trolley to move. After the control system issues a command, the trolley starts to move from the initial position (usually the end of the filter press 1) and fixes the first filter plate 102 by the mechanical arm, hook or magnetic device. The trolley moves along track 101, causing filter plates 102 to separate from adjacent plates, gradually opening the filter chamber. Due to the high viscosity of red mud, filter plates 102 need to be pulled apart slowly to avoid uneven filter cake adhesion. The trolley pauses after each plate is pulled apart, allowing the filter cake to fall off due to gravity, before continuing to pull the next plate. After unloading, the trolley moves in the opposite direction, pushing the filter plates 102 back together. Once the filter plates 102 are pressed together, the trolley returns to its initial position, awaiting the next operation. The working status sensor is a proximity switch, which monitors whether the plate-pulling trolley is in its initial state. The control box uses this proximity switch to determine whether the plate-pulling trolley is in its original position and then decides whether to control the oil pump 205 to operate, thus ensuring good lubrication for each operation of the plate-pulling trolley. This mechanism ensures that the oil pump 205 only starts when the filter press 1 is about to begin plate-pulling and unloading, avoiding prolonged operation of the oil pump 205 and reducing lubricant waste. Meanwhile, the upper side of the lubricating oil reservoir 2 has a return pipe and a return port. During the refueling process, if the reservoir is full or the oil pressure is too high, the return pipe will guide the excess fuel back to the reservoir or circulation system to prevent fuel leakage. The photoelectric sensor 302 monitors the open state of the filter plate 102. When the filter plate 102 completes the filtration operation and opens to form a sufficient gap, the photoelectric sensor 302 sends a signal to the system control box 3. Upon receiving the signal, the system control box 3 controls the solenoid valve 204 to open the lubricating oil passage, delivering the lubricating oil through the pipe 202 to the refueling nozzle 203, precisely spraying it onto the surface of the track 101. The refueling amount and timing are adjusted by the system control box 3 based on the activity state of the filter plate 102 and sensor feedback, thereby achieving precise control of the lubricating oil. This device is also equipped with multiple sensors, including an oil tank temperature sensor for real-time monitoring of the oil temperature, ensuring that the lubricating oil operates within a reasonable temperature range and avoiding excessively high or low oil temperatures from affecting the refueling effect. And a pressure sensor 206 at the output end of the fuel pump 205 is used to detect the output pressure of the fuel pump 205 in real time, so as to ensure the pressure is stable during the refueling process and prevent excessively high or low pressure from affecting the system performance.When the pressure sensor 206 detects stable pressure, oil is discharged normally from the outlet pipe. If the pressure is abnormal, the system can automatically adjust the pump speed or switch to return oil mode to maintain stability. This data can be displayed on the touchscreen of the control box, allowing users to monitor the liquid level, oil temperature, oil pressure, and the status of the refueling pump 205 and solenoid valve 204 in real time, thus ensuring stable system operation. In addition, this device is equipped with an ultrasonic level gauge to monitor the oil level in the lubricating oil reservoir 2 in real time, ensuring sufficient oil supply. If the oil level falls below the set threshold, the system control box 3 will issue an alarm signal, prompting the replenishment of lubricating oil to avoid insufficient lubrication leading to abnormal equipment operation.

[0021] The system control box 3 mainly contains a PLC and some switching components, namely relays. The PLC, based on signals from various sensors, controls the relay contactors to achieve various controls. According to the working cycle of the filter press 1, the system control box 3 only activates the lubrication process during the plate pulling and unloading stage. When the oil level is detected to be below the safety threshold, the oil temperature is abnormal, or the pressure exceeds the limit, the system control box 3 immediately cuts off the power to the lubrication pump 205 and triggers an audible and visual alarm. Simultaneously, a fault code is displayed on the human-machine interface (touchscreen), prompting maintenance personnel to intervene. Through the integrated touchscreen, the system control box 3 allows users to manually set lubrication parameters (such as lubrication volume, trigger gap threshold), view real-time data (oil temperature, oil pressure, liquid level status) and historical records, and supports manual start / stop of the equipment or forced lubrication, achieving flexible control. During the plate pulling process, the filter plates 102 are pulled apart one by one to form gaps. The photoelectric sensor 302 transmits the position signal of the filter plates 102 to the system control box 3 in real time via cable 301. When the gap of filter plate 102 reaches the set threshold, the control box controls the relay through PLC, and the lubricating oil is precisely sprayed onto the surface of track 101 through pipe 202 and oiling nozzle 203. like Figure 5 The image shown is an enlarged view of the fuel nozzle 203. When it is necessary to adjust the fuel spray angle of the fuel nozzle 203, simply loosen the bolts at the fixing ring 20302 and the adjusting rod 20303. At this time, the direction of the adjusting rod 20303 can be adjusted, thereby realizing the adjustment of the fuel spray angle of the fuel nozzle 203. The telescopic rod 20304 and the metal universal telescopic tube 20301 can adapt to the position change of the fuel nozzle 203, thereby preventing the fuel nozzle 203 from moving excessively.

[0022] Working Principle: During system operation, the working status sensor is connected to the plate-pulling trolley. This trolley, a standard technology, is integrated into the filter press 1 and is installed on both sides of the filter plates 102 to pull them apart. Specifically, the plate-pulling trolley is mounted on tracks 101 on both sides of the filter plates 102 of the filter press 1. It typically consists of a drive unit, a mechanical gripper, or a hook. Its function is to grasp and move the filter plates 102 one by one according to programmed instructions, achieving the separation and repositioning of the filter plates 102. After the filter press 1 completes the filtration of red mud, the filter plates 102 are tightly arranged, and the red mud is stored in the filter chamber. The hydraulic system releases the clamping plate, making room for the plate-pulling trolley to move. After the control system issues a command, the trolley begins to move from its initial position (usually the end of the filter press 1) and fixes the first filter plate 102 using a mechanical arm, hook, or magnetic device. The trolley moves along track 101, causing the filter plates 102 to separate from adjacent filter plates 102, gradually opening the filter chamber. Due to the high viscosity of red mud, the filter plates 102 need to be pulled open slowly to avoid uneven adhesion of the filter cake. After each filter plate 102 is pulled open, the process is paused to allow the filter cake to fall off due to gravity, and then the trolley continues to pull the next plate. After unloading, the trolley moves in the opposite direction, pushing the filter plates 102 back together. Once the filter plates 102 are pressed tightly, the trolley returns to its initial position, awaiting the next operation. A working status sensor monitors the working status of the filter press 1. When the filter press 1 is ready to pull the plates to unload, the sensor sends a signal to start the lubrication pump 205. Then, the photoelectric sensor 302 monitors the opening state of the filter plates 102. When the filter plates 102 have completed the filtration operation and opened to form a sufficient gap, the photoelectric sensor 302 sends a signal to the system control box 3. Upon receiving the signal, the system control box 3 controls the solenoid valve 204 to open the lubricating oil passage, delivering the lubricating oil through the pipe 202 to the lubrication nozzle 203, which is then precisely sprayed onto the surface of the track 101. The amount and timing of lubricant addition are adjusted by the system control box 3 based on the activity status of the filter plate 102 and sensor feedback, thereby achieving precise control of the lubricating oil. This device is also equipped with multiple sensors, including an oil tank temperature sensor for real-time monitoring of oil temperature to ensure the lubricating oil operates within a reasonable temperature range, preventing excessively high or low temperatures from affecting the lubrication effect; and a pressure sensor 206 at the output of the lubricating pump 205 to detect the output pressure of the pump in real-time, ensuring stable pressure during the lubrication process and preventing excessively high or low pressure from affecting system performance. This data can be displayed on the touchscreen of the control box, allowing users to view the liquid level, oil temperature, oil pressure, and the status of the lubricating pump 205 and solenoid valve 204 in real time. Furthermore, this device is equipped with an ultrasonic level gauge to monitor the oil level in the lubricating oil reservoir 2 in real-time, ensuring sufficient oil supply. If the oil level falls below a set threshold, the system control box 3 will issue an alarm signal, prompting the replenishment of lubricating oil.
