Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic aluminum, in particular to a feeder oiling and lubricating device. Background Art

[0002] Electrolytic aluminum, as the core production method of the modern aluminum industry, is the process of extracting high-purity aluminum from alumina through electrolysis. It uses cryolite as a solvent and alumina as a solute, and uses a strong direct current to carry out an electrolytic reaction in the electrolytic cell, thereby precipitating aluminum liquid on the cathode. Due to its high purity and excellent physical and chemical properties, electrolytic aluminum is widely used in aerospace, automobile manufacturing, construction, packaging, electrical and electronic appliances and other fields, becoming one of the indispensable important materials for modern industry. However, the production process of electrolytic aluminum is also accompanied by high energy consumption and certain environmental pollution problems. Therefore, with the increasing global requirements for sustainable development and environmental protection, the electrolytic aluminum industry is also constantly exploring the innovation and application of energy-saving, emission reduction and environmental protection technologies.

[0003] Lubrication of the tank top equipment is essential maintenance during daily electrolytic aluminum production.

DETAILED DESCRIPTION

[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 5 The lubricating device for a feeder shown in the figure includes a three-way valve 1, a circular opening is provided inside the three-way valve 1, and an air inlet 2, an air outlet 4, and an oil inlet 6 are respectively provided on the three-way valve 1, which are connected to the circular opening to form a passage. The air inlet 2 and the air outlet 4 are connected to the main pipe of the feeder, and the outside of the air inlet 2 and the air outlet 4 are both provided with threads. The air inlet 2 is connected to the air inlet pipe 3 through threads, and the air outlet 4 is connected to the air outlet pipe 5 through threads. The oil inlet 6 is connected to the oil inlet pipe 8, and the oil inlet pipe 8 inputs lubricant into the main pipe. Through the above technical solution, lubricant can automatically enter the feeder, which improves the lubrication quality of the feeder, reduces the frequency of personnel disassembling and assembling the feeder, reduces the workload of employees, saves maintenance hours, reduces the difficulty and labor intensity of work, improves work efficiency, and reduces safety hazards. A fixing ring 7 is rotatably installed on the oil inlet 6, and the inner side of the fixing ring 7 is provided with threads. The outer side of the oil inlet pipe 8 is provided with threads and is fixed in conjunction with the fixing ring 7.

[0025] A valve body 17 is rotatably installed in the three-way valve 1. The valve body 17 is circular and blocks the air inlet 2, the air outlet 4 and the oil inlet 6 in the circular opening of the three-way valve 1. A connecting path 19 is provided in the valve body 17. The rotating connecting path 19 connects the air inlet 2 and the air outlet 4. A secondary channel 18 is provided in the three-way valve 1. The secondary channel 18 is connected to the air outlet 4. The rotating connecting path 19 connects the oil inlet 6 and the secondary channel 18. A one-way valve 20 is installed between the air outlet 4 and the secondary channel 18, and the lubricating oil can flow from the secondary channel 18 to the air outlet 4. When the connecting path 19 connects the air inlet 2 and the air outlet 4, the oil inlet 6 and the auxiliary channel 18 are blocked, and the air cylinder and the feeder are ventilated normally. When lubricating oil is needed, the valve body 17 is rotated to block the air outlet 4 and the air inlet 2, and the lubricating oil flows from the oil inlet 6 to the auxiliary channel 18. The lubricant in the auxiliary channel 18 flows to the air outlet 4 through the one-way valve 20. Through the above technical solution, the timing of adding lubricating oil can be switched freely, and during the adding of lubricating oil, it can be ensured that the lubricating oil will not affect the original air intake pipeline, and at the same time, the air intake pipeline will not enter the auxiliary channel 18 when ventilated.

[0026] A rotating cap 12 is fixedly mounted on the top of the valve body 17. The cross-shaped rotating cap 12 is conveniently rotated by hand. A sealing cap 10 is attached to the top of the three-way valve 1. This cap is equipped with a handle 11 and covers the rotating cap 12. A sealing ring 9 is fixed to the three-way valve 1, which contacts the sealing cap 10 for a seal. This technical solution allows for easy manual rotation of the rotating cap 12 to switch the valve body 17, while the sealing cap 10 also protects against dust and ensures long service life.

[0027] The three-way valve 1 is provided with a plurality of engaging grooves 16, and an engaging block 15 is slidably mounted on the rotating cap 12. A spring 13 is fixedly mounted between the engaging block 15 and the rotating cap 12, and the engaging block 15 can be engaged and fixed in the engaging grooves 16. Through the above technical solution, the stability of the rotating cap 12 and the valve body 17 can be ensured after switching, and they do not rotate when oil or air is passed. Moreover, the cooperation between the engaging block 15 and the engaging grooves 16 can achieve precise positioning and control of the valve size.

[0028] Working principle: Connect the air inlet 2 and the air outlet 4 to the main air inlet pipe of the feeder, tighten the air inlet pipe 3 and the air outlet pipe 5 by rotating the knob, insert the oil inlet 6 into the oil inlet pipe 8, and then rotate the fixing ring 7 to allow the fixing ring 7 to fix the oil inlet pipe 8. Under normal conditions, the connecting path 19 connects the air inlet 2 and the air outlet 4 to work. When maintenance and maintenance are required, hold the handle 11 and pull out the sealing cover 10 upward with force, then move the snap-fit ​​block 15 to disengage the snap-fit ​​block 15 from the snap-fit ​​groove 16, and then rotate the rotating cap 12 until the oil inlet 6 is connected to the secondary channel 18. At this time, there is also a snap-fit ​​groove 16 at the corresponding position. Loosen the snap-fit ​​block 15, and under the action of the spring 13, the snap-fit ​​block 15 is clamped into the snap-fit ​​groove 16 for fixation, and then send lubricating oil to the feeder and the cylinder.
