Full-automatic anode busbar lifting frame hydraulic system realizing energy saving

Abstract

The invention provides a full-automatic anode busbar lifting frame hydraulic system realizing energy saving. A motor (1), a coupler / bell jar (2), a hydraulic pump (3), a reversing valve (5), a hydraulic motor (6) and a hydraulic oil tank (7) of the system are connected through pipelines and joints which are used for connecting hydraulic components; the motor (1) is used for driving the hydraulicpump (3) to feed a hydraulic oil pump in the hydraulic oil tank (7) into a high pressure oil pipeline through the coupler / bell jar (2); the high pressure oil pipeline is connected to the reversing valve (5) and the hydraulic motor (6) in sequence; the reversing valve (5) is used for controlling the positive rotation or negative rotation of the hydraulic motor (6); and a pump outlet valve group (8) is also arranged in the high pressure oil pipe at the output side of the hydraulic pump (3). The system reduces the loss of energy sources, the failure rate of the components and the impact on equipment, realizes zero-load starting and improves the quality of products, the intellectualization, the integration and the intelligent operability of the products.

Description

(1) Technical field [0001] The invention relates to a fully automatic anode bus lifting frame hydraulic system, in particular to a fully automatic anode bus lifting frame hydraulic system which can realize zero-load startup with low oil return pressure. (2) Background technology [0002] In the busbar lifting frame, the loosening and tightening of the small box clamps is the key operation when lifting the busbar in the electrolytic aluminum industry. The traditional busbar lifting operation is manually operated, and a special wrench is required to complete the loosening of the small box clamps. and tighten. However, manual operation will cause the following problems: ①When manually loosening and tightening the small box clamps, the operator needs to stand on the high-temperature slot cover to operate, which may easily cause personal injury or burn accidents; ②The small box clamps cannot be loosened. In place or insufficient tightening torque, damage to equipment and persona...

Problems solved by technology

However, manual operation will cause the following problems: ①When manually loosening and tightening the small box clamps, the operator needs to stand on the high-temperature slot cover to operate, which may easily cause personal injury or burn accidents; ②The small box clamps cannot be loosened. In place or insufficient tightening torque, damage to equipment and personal injury; ③Multiple personnel are required to cooperate during operation, resulting in low efficiency, high cost, and long operation time; ④Misoperation may easily lead to vicious accidents such as explosions

[0006] In such a hydraulic system, there are mainly the following problems: there is a problem that the torque of the hydraulic torque wrench varies greatly and is not accurate enough, and the torque of tightening or loosening the small box clamp cannot be accurately set or adjusted, which seriously affects production. safety during the process; in addition, there is a recoil damage fault to the hydraulic pump when the motor starts and stops, usually there is a difficult problem that the hydraulic motor shaft seal is washed away due to the high back pressure of the oil return; in addition, during the start-up process, the traditional The system design is not energy-saving and environmentally friendly, and does not conform to the concept of energy-saving and emission reduction, which makes the start-up load of the entire system very large and wastes energy; and with the use of equipment, the cleanliness of the oil will gradually decrease, causing wear and tear of components, making the entire system not stable. Stable; the whole system is not integrated and intelligent enough, this solution can improve the intelligent operability of the product, the degree of visualization is higher, and the layout of each component is more compact, and the layout of pipelines is more concise, beautiful and reasonable; In the system, under the premise of satisfying the above basic functions, the design of the hydraulic system cannot be made safer, more perfect and more humanized
