Both baf fle plates are fixed inside the reactor body and are perpendicular to the width direction of the reactor body . The acid spray assembly comprises a pumping unit , two first adj ustment valves , and two first noz zles . The inlets of the two first noz zles are respectively connected to the outlet of the pumping unit through the two first adj ustment valves . Both first noz zles are located between the two baf fle plates , and their outlets are directed towards the two baf fle plates . The opening and closing of the two first adj ustment valves are determined based on the vibration direction of the reactor body in the width direction .

The baffle plate, after being impacted, will drive the reactor body to vibrate in the direction towards the same side as the baffle plate, thereby opposing the real-time vibration direction of the reactor body. This reduces the vibration intensity of the reactor body, improves safety, and extends the lifespan of the precision instruments installed on the reactor.

Detailed Description

[0032] To make the obj ectives , technical solutions , and advantages of this invention clearer, the following detailed description is provided in conj unction with the drawings and embodiments . It should be understood that the speci fic embodiments described here are intended only to illustrate the invention and are not meant to limit the scope of the invention .

[0033] To address the technical problem of severe shaking of the reactor body during operation due to intense reactions of the reactants and the action of the stirring device in a high-pressure reactor for laterite nickel ore , which poses safety risks and signi ficantly shortens the li fespan of precision instruments installed on the reactor, this invention provides a stabili zation system for the high-pressure reactor . The system is designed to reduce vibration during operation, enhance safety, and extend the li fespan of the precision instruments mounted on the reactor .

[0034] It should be noted that the stabili zation system for the high-pressure reactor for laterite nickel ore described in this invention is applicable not only to high-pressure reactors for laterite nickel ore but also to other similar equipment . For the sake of simplicity, the following description will use the application of the stabili zation system to high-pressure reactors for laterite nickel ore as an example . The principles and applications of the stabili zation system in other types of equipment are essentially the same as those in high-pressure reactors for laterite nickel ore , and thus will not be repeated here .

[0035] Please refer to FIG . 1 , Figure 1 is a schematic diagram of the structure of the stabili zation system for a high-pressure reactor for laterite nickel ore according to an embodiment of this invention . The stabili zation system includes a reactor body 1 , a vibration detection mechanism 2 , and a vibration reduction mechanism 3 .

[0036] Please refer to FIGs . 1 to 3 . The vibration detection mechanism 2 is positioned on both sides of the reactor body 1 in the width direction and is used to detect the vibration direction of the reactor body 1 in the width direction . In this embodiment , the focus is on detecting the vibration direction of the reactor body 1 in the width direction because the amplitude of vibration is generally larger in the width direction compared to the length direction . Therefore , the vibration detection mechanism 2 is used to monitor the reactor body 1 ' s vibration in the width direction, and the vibration reduction mechanism 3 is used to dampen the vibrations in this direction .

[0037] The vibration reduction mechanism 3 includes two baf fle plates 31 and an acid spray assembly 32 . Both baf fle plates 31 are fixed inside the reactor body 1 and are perpendicular to the width direction of the reactor body 1 . The acid spray assembly 32 consists of a pumping unit 321 , two first adj ustment valves 322 , and two first noz zles 323 . The inlets of the two first noz zles 323 are connected to the outlets of the pumping unit 321 via the two first adj ustment valves 322 . The two first noz zles 323 are positioned between the two baf fle plates 31 , and their outlets face towards the respective baf fle plates 31 . The opening and closing of the two first adj ustment valves 322 are determined based on the vibration direction of the reactor body 1 in the width direction .

[0038] During operation, the vibration detection mechanism 2 detects the real-time vibration direction of the reactor body 1 in the width direction . When the vibration direction shi fts towards one side , the first adj ustment valve 322 on the opposite side is opened, causing the first noz zle 323 on the opposite side to spray acid and impact the corresponding baf fle plate 31 . The impact on the baf fle plate 31 then drives the reactor body 1 to vibrate in the direction of the baf fle plate 31 , which is opposite to the real-time vibration direction of the reactor body 1 . This reduces the vibration intensity of the reactor body 1 , enhances safety, and extends the li fespan of the precision instruments mounted on the reactor .

[0039] In one embodiment , as shown in FIGs . 3 and 4 , the vibration detection mechanism consists of two units . These two vibration detection mechanisms are placed on both sides of the reactor body in the width direction . The vibration detection mechanism 2 includes a detection base 21 and a pressure sensor 22 . One end of the pressure sensor 22 is connected to the detection base 21 , and the other end is connected to the side wall of the reactor body 1 . In this embodiment , when the reactor body vibrates in the width direction and shi fts towards one side , the pressure sensor 22 on that side will measure an increased pressure value , while the pressure sensor 22 on the opposite side will measure a decreased pressure value . Therefore , the real-time vibration direction of the reactor body in the width direction can be detected by the two pressure sensors 22 .

[0040] In one embodiment , as shown in FIGs . 3 and 4 , the vibration detection mechanism 2 also includes a first mounting plate 23 , a telescopic spring 24 , and a second mounting plate 25 . The first mounting plate 23 is fixed to the other end of the pressure sensor 22 , and the two ends of the telescopic spring 24 are connected to the first mounting plate 23 and the second mounting plate 25 , respectively . The second mounting plate 25 is fixed to the side wall of the reactor body 1 . In this embodiment , when the reactor body vibrates in the width direction and shi fts towards one side , the telescopic spring 24 on that side will contract , causing the pressure sensor 22 on that side to measure an increased pressure value . Conversely, the telescopic spring 24 on the opposite side will extend, and the pressure sensor 22 on that side will measure a decreased pressure value . Therefore , the real-time vibration direction of the reactor body in the width direction can be detected by the two pressure sensors 22 .

[0041] In one embodiment , as shown in Figures 3 and 4 , the pressure sensor 22 is a ceramic pressure sensor .

[0042] In one embodiment , as shown in Figs . 2 to 5 , the acid spraying component 32 also includes an acid inlet pipe 324 , a four-way valve 325 , a second regulating valve 326 , and a second spray head 327 . The acid inlet pipe 324 is fixed to the reactor body 1 . The first port of the four-way valve 325 is connected to one end of the acid inlet pipe 324 . The second and third ports of the four-way valve 325 are connected to the two first regulating valves 322 . The fourth port of the four-way valve 325 is connected to one end of the second regulating valve 326 . The other end of the second regulating valve

[0043] 326 is connected to the inlet of the second spray head 327 . The outlet of the second spray head 327 is oriented downward . In this embodiment , by setting up the second regulating valve 326 and the second spray head 327 , and with the outlet of the second spray head 327 oriented downward, the spraying of the acid liquid from the second spray head

[0044] 327 will not af fect the lateral movement of the reactor body 1 . During operation, i f the vibration intensity of the reactor body 1 is weak and damping is not needed through the damping mechanism 3 , the acid liquid can be fully sprayed from the second spray head 327 , without being sprayed from the first spray head 323 . This avoids causing the reactor body 1 to vibrate in the hori zontal direction due to the acid liquid being sprayed from the first spray head 323 .

[0045] In one embodiment , as shown in Figs . 2 to 5 , the acid spraying component 32 also includes a controller . The controller is electrically connected to the two pressure sensors 22 , the two first regulating valves 322 , and the two second regulating valves 326 .

[0046] When the pressure values of the two pressure sensors 22 are equal , it indicates that there is no vibration of the reactor body 1 in the width direction . In this case , both first regulating valves 322 are closed, and the second regulating valve 326 is opened to ensure that all the acid liquid is sprayed out from the second noz zle 327 .

[0047] When the pressure value of one pressure sensor 22 is greater than that of the other pressure sensor 22 , the first regulating valve 322 on the same side as the pressure sensor with the smaller pressure value is opened . This causes the first noz zle 323 on the same side as the pressure sensor with the smaller pressure value to spray acid liquid and impact the corresponding side ' s baf fle plate 31 . The impact on the baf fle plate 31 will then drive the reactor body 1 to vibrate towards the same side as the baf fle plate 31 , counteracting the real-time vibration direction of the reactor body 1 , thereby reducing its vibration intensity .

[0048] In one of the embodiments , referring to Figs . 2-5 , the pumping unit 321 includes an acid storage tank 3211 and a pump body 3212 . The inlet of the pump body 3212 is connected to the acid storage tank 3211 , and the outlet of the pump body 3212 is connected to the other end of the acid supply pipe 324 . It should be understood that , due to the continuous reaction inside the high-pressure nickel laterite reactor, materials and acid liquids are continuously introduced into the high-pressure reactor during production . Therefore , the input of acid liquid is continuous , which allows the kinetic energy of the continuously supplied acid liquid to be used as the power source to overcome the vibration of the reactor body 1 . In one of the embodiments, referring to Figs. 2-5, the pumping unit 321 also includes a first pipe 3213. One end of the first pipe

[0049] 3213 is inserted into the acid storage tank 3211, and the other end of the first pipe 3213 is connected to the inlet of the pump body 3212.

[0050] In one of the embodiments, referring to Figs. 2-5, the pumping unit 321 also includes a second pipe 3214. One end of the second pipe

[0051] 3214 is connected to the outlet of the pump body 3212, and the other end of the second pipe 3214 is connected to the other end of the acid inlet pipe 324.

[0052] In one of the embodiments, referring to Figs. 2-5, the pumping unit 321 also includes a flexible hose 3215. One end of the flexible hose 3215 is connected to the other end of the second pipe 3214, and the other end of the flexible hose 3215 is connected to the other end of the acid inlet pipe 324.

[0053] In one of the embodiments, referring to Fig. 1, the upper end of the reactor body 1 is provided with a feed inlet 11, and the lower end of the reactor body 1 is provided with a discharge outlet 12. The discharge outlet 12 is equipped with a discharge valve 13.

[0054] In one of the embodiments, referring to Figures 1 and 2, the reactor body 1 is also provided with a stirring device 4. The stirring device 4 includes a stirring shaft 41, stirring blades 42, and a stirring motor 43.

[0055] To better understand this invention, the technical solutions of this invention are detailed below with reference to Figs. 1 to 5 : During use, the vibration detection mechanism 2 detects the real-time vibration direction of the reactor body 1 in the width direction. When the vibration direction is toward one side, the first adjustment valve 322 on the opposite side is opened, causing the first nozzle 323 on the opposite side to spray acid and impact the corresponding baffle plate 31. The baffle plate 31, upon impact, will cause the reactor body 1 to vibrate in the direction of the same side as the baffle plate 31, which is opposite to the real-time vibration direction of the reactor body 1. This reduces the vibration intensity of the reactor body 1, enhances safety, and extends the lifespan of the precision instruments installed on the reactor. The speci fic embodiments described above are not intended to limit the scope of protection of this invention . Any various other modi fications and alterations made according to the technical concepts of this invention should be included within the scope of the claims of this invention .
