Problems solved by technology

Nowadays, the country is doing everything possible to reduce pollution and reduce the impact of smog on people's health. Although the current production capacity of iron and steel enterprises is excessive, some enterprises are operating at a loss, and it is difficult to raise funds. However, the hydraulic transmission of the stepping heating furnace must be used for production. Therefore, this equipment must be equipped. Innovative transformation adopts hydraulic balance

Embodiment 1

[0036] Such as figure 1 Shown is a single-cylinder hydraulic balance energy-saving retrofit device for a walking heating furnace that has been produced, which is a complete and independent hydraulic balance system. It adopts a single large-capacity welded high-pressure gas tank 1 (for the structure details of the large-capacity welded high-pressure gas tank 1, see image 3 ), a single large-capacity welded high-pressure gas tank 1 is connected to the high-pressure ball valve group 2, and then connected to the piston accumulator 3-1, and the piston accumulator 3-1 is connected to the safety valve group installed on it, and the safety valve group is one The oil return port is connected with the oil return line T1. The high-pressure oil port of the safety valve group is connected to the control valve group 1 4-1, and then connected to the 5-piston chamber port of the hydraulic cylinder with position control to push the lifting platform up. When the lifting platform descends, th...

Embodiment 2

[0047] Such as figure 2As shown, it is another double-cylinder hydraulic balance energy-saving transformation device for walking heating furnace that has been produced. It includes the two hydraulic cylinders of the original system, but the original piston cylinder is changed into a plunger cylinder, and the original The oil inlet pipe with the piston rod is removed and blocked with a valve so that it can be reinstalled when the original system is restored. The original oil inlet is equipped with an air filter, or connected to a high-level oil tank to keep oil in the cylinder cavity and prolong the life of the seal. It is connected with the original hydraulic cylinder through a three-way valve, so that the two systems can be switched on and off at any time, and all other equipment, connection methods, and functions are the same as figure 1 same plan. Although it is a hydraulic control cylinder with a small flow rate to control the position and speed of the two hydraulic cyl...

Abstract

The invention provides a produced stepping heating furnace hydraulic balance energy-saving transformation device. Air is supplied to an energy accumulator through an air container, oil pressure is provided to a piston cavity in a hydraulic cylinder through a valve, and a rack is pushed to go up; and when the rack contacts a steel billet fixed onto the rack, a valve of the energy accumulator is controlled to be closed, meanwhile, the valve is opened, the energy accumulator supplies the oil pressure to the hydraulic cylinder so as to continuously lift the rack and the steel billet, and the valveis closed after in place. Reverse actions are carried out during lowering and lifting, the rack and the steel billet are lowered by self-weight, and the pressure in the piston rod cavity in the hydraulic cylinder is added so as to press high-pressure oil in the piston cavity into various energy accumulators. One cycle is accomplished. A lifting speed and a lifting position are controlled througha proportional valve 7. The produced stepping heating furnace hydraulic balance energy-saving transformation device has the advantages of simplicity and convenience in design and load adjustment (a billet weight change). Energy conservation, a synergistic effect and emission reduction are realized. An original system keeps the same. Two systems can be quickly switched over to operate so as to ensure production. Equipment and original devices are mature and reliable so as to be less in investment. The investment can be returned after one year. Transformation can be accomplished in overhaul.

Description

technical field [0001] The present invention relates to a manufactured hydraulic balance energy-saving transformation device for a walking heating furnace, which adopts a gas tank and a piston accumulator to realize the energy storage of the descending potential energy of the lifting platform of the walking heating furnace and the billet, and then store the energy in the accumulator. It is used to lift the lifting platform and the steel billet to achieve a complete balance of the two loads, so that it only needs to overcome some small resistances in the transmission and movement of the liquid gas, valves and cylinders, so as to achieve the maximum energy saving. Some resistance system also exists, so it can be approximated that the heavy-duty lifting movement of the walking heating furnace is running without loss. [0002] The invention is used in pneumatic, hydraulic, mechanical and other transmissions, and belongs to the fields of pneumatic, hydraulic, mechanical, gas, hydra...
