Description

Technical Field

[0001] The present application relates to the technical field of flash tanks, and in particular to a flash tank stabilization system. Background Art

[0002] The flash tank is a key equipment in the high pressure acid leaching (HPAL) process of laterite nickel ore. It is mainly used to treat the slurry after high temperature and high pressure acid leaching, and realize the rapid vaporization of water in the slurry and the separation of gas and liquid through the flash process.

[0003] The flash tank is prone to vibration during operation, and the vibration is mainly caused by the flash valve on the flash tank. The flash valve is an automatic control valve used to control fluid pressure and flow. When high-temperature and high-pressure fluid passes through the flash valve, the fluid flows from the high-pressure area to the low-pressure area, and its pressure drops rapidly. At this time, part of the fluid will quickly change from liquid to gas, resulting in flash evaporation. When the phase state and pressure of the fluid in the flash valve change drastically, it is easy to cause the flash valve to vibrate, which in turn drives the flash tank to vibrate.

[0004] Long-term and violent shaking of the flash tank may cause the flash tank pipeline fixing structure to loosen, thus posing certain safety hazards. Summary of the invention

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0019] In order to solve the technical problem that long-term violent shaking of the flash tank may cause the loosening of the flash tank pipeline fixing structure, thereby bringing certain safety hazards, the present application provides a flash tank stabilization system, which can reduce the vibration of the flash tank during operation, thereby preventing the loosening of the flash tank pipeline fixing structure and improving safety.

[0020] See also Figure 1 , Figure 1 Schematic diagram of the structure of a flash tank stabilization system in one embodiment of the present application. The flash tank stabilization system includes a support mechanism 1 and a vibration reduction assembly 2.

[0021] The support mechanism 1 includes a base 11 , a column 12 and a top plate 13 . The base 11 is used to fix the flash tank 3 , and the column 12 is used to connect the base 11 and the top plate 13 .

[0022] The vibration reduction assembly 2 includes a hydraulic cylinder 21, a pressure plate 22, a strain gauge 23 and an oil pump 24. The cylinder body of the hydraulic cylinder 21 is fixed to the top plate 13. The output shaft of the hydraulic cylinder 21 is fixedly connected to one end of the pressure plate 22. The other end of the pressure plate 22 is connected to one end of the strain gauge 23. The other end of the strain gauge 23 is connected to the upper end of the flash tank 3. The oil pump 24 is used to supply oil to the hydraulic cylinder 21 and can adjust the output pressure of the oil pump 24 according to the pressure detected by the strain gauge 23 so that the pressure of the flash tank 3 on the pressure plate 22 is equal to the pressure of the hydraulic cylinder 21 on the pressure plate 22.

[0023] The vibration of the flash tank 3 during operation is mainly in the up-and-down direction. When the flash tank 3 vibrates upward, the pressure on the strain gauge 23 increases, and the oil pump 24 increases the output pressure, so that the pressure of the flash tank 3 on the pressing plate 22 is equal to the pressure of the hydraulic cylinder 21 on the pressing plate 22. Therefore, the pressure increased by the oil pump 24 can limit the upward vibration of the flash tank 3, reduce the vibration of the flash tank 3 during operation, thereby preventing the pipeline fixing structure of the flash tank 3 from loosening and improving safety.

[0024] It should be understood that the oil pump 24 is a hydraulic pump, which is a hydraulic system power element that is driven by an engine or an electric motor and converts mechanical energy into hydraulic energy. It sucks oil from the hydraulic oil tank, forms pressure oil and discharges it, and finally sends it to the actuator (such as a hydraulic cylinder, a hydraulic motor, etc.). The operation of the hydraulic pump is based on the change in the volume of the pump chamber. When the volume of the pump chamber decreases, the oil is compressed and pressure is generated; when the volume of the pump chamber increases, a vacuum is formed and oil is sucked from the oil tank. This periodic change in volume enables the hydraulic pump to continuously suck and discharge oil, providing stable pressure oil for the hydraulic system. In this embodiment, the inlet of the oil pump 24 is connected to the oil tank (not shown), and the oil tank is filled with hydraulic oil.

[0025] In one embodiment, see Figure 1 and Figure 2 The base 11 is fixed to the ground 4 via a plurality of anchor bolts 111, so that the base 11 can be fixed to prevent the base 11 from vibrating. Preferably, a slot is provided on the ground 4, and the base 11 is clamped in the slot, so that the base 11 can be further limited to improve the stability of the base 11.

[0026] In one embodiment, see Figure 1 and Figure 2 The support mechanism 1 further includes a plurality of lower inclined rods 14 , the upper end of each of the lower inclined rods 14 is fixed to the flash tank 3 , and the lower end of each of the lower inclined rods 14 is fixed to the base 11 .

[0027] In one embodiment, see Figure 1 and Figure 2 The lower end of each lower inclined rod 14 is fixed to the base 11 via a plurality of locking screws 141 .

[0028] In one embodiment, see Figure 1 and Figure 3The vibration reduction assembly 2 also includes two upper inclined rods 25, the lower ends of the two upper inclined rods 25 are respectively fixed to the two sides of the upper end of the flash tank 3, and the two upper inclined rods 25 are inclined and arranged opposite to each other; the number of the hydraulic cylinder 21, the pressure plate 22, the strain gauge 23 and the oil pump 24 is two, the cylinder bodies of the two hydraulic cylinders 21 are fixed to the top plate 13, the output shafts of the two hydraulic cylinders 21 are respectively fixedly connected to one end of the two pressure plates 22, the other ends of the two pressure plates 22 are respectively connected to one end of the two strain gauges 23, and the other ends of the two strain gauges 23 are respectively connected to the upper ends of the two upper inclined rods 25. In this embodiment, by setting two groups of vibration reduction assemblies 2, the swing and vibration of the flash tank 3 can be effectively dealt with.

[0029] In one embodiment, see Figure 1 and Figure 3 The pressure plate 22 is provided with a plurality of guide holes, a pressure block 26 is fixed to the upper end of the upper inclined rod 25, and a plurality of guide columns 261 are fixed to the pressure block 26. The guide columns 261 are respectively and one by one slidably inserted into the guide holes. The strain gauge 23 is arranged between the pressure block 26 and the pressure plate 22. When the flash tank 3 vibrates upward, the pressure block 26 vibrates upward and approaches the pressure plate 22. The pressure on the strain gauge 23 increases, and the oil pump 24 increases the output pressure, so that the pressure of the flash tank 3 on the pressure plate 22 is equal to the pressure of the hydraulic cylinder 21 on the pressure plate 22. The function of the guide column 261 is to prevent the pressure plate 22 from moving sideways.

[0030] In one embodiment, see Figure 1 and Figure 3 A limiting protrusion 2611 is formed at the end of the guide column 261 to prevent the pressing plate 22 from separating from the guide column 261 .

[0031] In one embodiment, see Figure 1 and Figure 3 A piston 211 is slidably disposed in the cylinder body of the hydraulic cylinder 21 , and an output shaft 212 of the hydraulic cylinder 21 is fixedly connected to the piston 211 .

[0032] In one embodiment, see Figure 1 and Figure 3 The outlet of the oil pump 24 is connected to the oil inlet of the hydraulic cylinder 21 via a high-pressure hose 27 .

[0033] In order to better understand this application, the following Figures 1 to 3The technical solution of the present application is described in detail: when in use, the vibration of the flash tank 3 is mainly in the up-and-down direction. When the flash tank 3 vibrates upward, the pressure on the strain gauge 23 increases, and the oil pump 24 increases the output pressure, so that the pressure of the flash tank 3 on the pressing plate 22 is equal to the pressure of the hydraulic cylinder 21 on the pressing plate 22. Therefore, the pressure increased by the oil pump 24 can limit the upward vibration of the flash tank 3, reduce the vibration of the flash tank 3 when working, thereby preventing the pipeline fixing structure of the flash tank 3 from loosening and improving safety.

[0034] The specific implementation methods of the present application described above do not constitute a limitation on the protection scope of the present application. Any other corresponding changes and modifications made according to the technical concept of the present application should be included in the protection scope of the claims of the present application.
