[0044] As Figures 1-4 The reaction kettle descaling system can be applied to the descaling operation of the high-pressure reaction kettle, and can uniformly and comprehensively spray descaling into the high-pressure reaction kettle and brush the inner wall of the high-pressure reaction kettle, thereby improving the descaling effect and descaling efficiency.

[0045] It is to be noted that the reaction kettle descaling system of the present embodiment is used in but not limited to the high-pressure reaction kettle, and can also be applied to other equipment that needs to be descaled. In the present embodiment, only the reaction kettle descaling system applied to the high-pressure reaction kettle for the hydrometallurgy of laterite nickel ore is taken as an example for description, and the principle of the reaction kettle descaling system applied to other equipment is substantially the same as that applied to the present equipment, which will not be described herein.

[0046] The reaction kettle descaling system comprises a kettle body 1, a cleaning device 2, and a washing and brushing device 3. The kettle body 1 has a closable cleaning port 11. In the normal production process, the cleaning port 11 is in a closed state, and in the descaling operation, the cleaning port 11 is opened.

[0047] The cleaning device 2 comprises a water pump 21, a pipeline 22, a sprayer 23, and a plugging device 24. The water pump 21 is in communication with the sprayer 23 through the pipeline 22. The water pump 21 is arranged outside the kettle body 1 and is connected with a flushing water supply or storage device. The pipeline 22 penetrates through the cleaning port 11 so that the sprayer 23 extends into the kettle body 1. The sprayer 23 has a plurality of water outlets 2331 and is rotatably connected with the pipeline 22. The water pump 21 delivers flushing water into the sprayer 23 through the pipeline 22, and the sprayer 23 can rotate under the action of the flushing water. The plugging device 24 is arranged on the pipeline 22 to plug the cleaning port 11. The washing and brushing device 3 is used for brushing the inner wall of the kettle body 1.

[0048] The flushing water is pushed by the water pump 21 to flow at a high speed, thereby pushing the sprayer 23 to rotate, and at the same time, the flushing water is sprayed from the sprayer 23 to be sprayed in all directions in the high-pressure reaction kettle to impact the scale bodies everywhere, so that most of the scale on the inner wall can be effectively removed, the labor intensity of the descaling workers is greatly reduced, and the descaling effect and descaling efficiency are improved by combining the washing and brushing of the inner wall of the kettle body 1 by the washing and brushing device 3.

[0049] In some embodiments, a tubular structure extends outward from the vessel body 1 to form a cleaning port 11. This tubular structure is preferably arranged at an angle, so that the pipe 22 and the sprayer 23 extend obliquely into the vessel body 1. The cleaning port 11 is located at a suitable position on the vessel body 1, including but not limited to the top or side surface, so that the sprayer 23 can extend into a suitable position inside the vessel body 1 to spray rinsing water evenly and comprehensively.

[0050] In some embodiments, the water pump 21 is an ultra-high pressure pulse-type water pump. Ultra-high pressure refers to pressurizing the flushing water to over 100 MPa, so that the flushing water reaches a sufficiently high velocity and kinetic energy to drive the sprayer 23 to rotate at the required speed, and the sprayed flushing water also has sufficient kinetic energy to impact the scale. Pulsed output of flushing water also achieves better spraying effect.

[0051] In some embodiments, the pipe 22 includes a first pipe 221 and a second pipe 222. The first pipe 221 connects the water pump 21 and the plug 24, and the second pipe 222 connects the plug 24 and the sprayer 23. The first pipe 221 is located outside the vessel body 1, and the second pipe 222 passes through the cleaning port 11 and enters the vessel body 1.

[0052] In a preferred embodiment, the first pipe 221 is a flexible hose to allow for flexible arrangement of the water pump 21. The second pipe 222 is a rigid pipe used to connect and support the sprayer 23, so that the sprayer 23 is located in a suitable position inside the vessel body 1.

[0053] like Figure 3 As shown, in some embodiments, a groove 2221 is formed at the end of the second pipe 222 near the sprayer 23. The sprayer 23 is fitted onto the opening of the second pipe 222 and has a corresponding retaining block 231. The retaining block 231 engages with the groove 2221 and can rotate freely within the groove 2221. This allows the sprayer 23 to rotate relative to the pipe 22. In other embodiments, other rotating connection methods may also be used.

[0054] In some embodiments, the sprayer 23 includes a housing 232 and a plurality of nozzles 233. The housing 232 has an inner cavity, and the nozzles 233 are distributed on the outer surface of the housing 232, with the water outlet 2331 of the nozzles 233 communicating with the inner cavity. The pipe 22 also communicates with the inner cavity, and the flushing water first enters the inner cavity and then is sprayed out from each nozzle 233. The housing 232 may have a spherical or near-spherical structure, and the nozzles 233 are evenly distributed on the outer surface of the housing 232, thereby achieving the effect of spraying flushing water in all directions.

[0055] In some embodiments, the sprayer 23 further includes a turbine (not shown) built into the inner cavity, the turbine being fixedly connected to the housing 232, the pipe 22 being arranged toward the turbine, and the flushing water rushing out from the pipe 22 impacting the turbine to cause the turbine to drive the sprayer 23 to rotate.

[0056] As Figure 4 shown, in some other embodiments, no turbine is arranged in the shell 232, but at least part of the water outlet holes 2331 of the nozzles 233 are arranged in the same rotational direction, i.e. arranged clockwise or counterclockwise, while the water outlet holes 2331 of the other nozzles 233 are arranged radially, without hindering the rotation of the sprayer 23. Thus, the flushing water pushes the sprayer 23 to rotate when it is sprayed from the water outlet holes 2331.

[0057] In some embodiments, a flange is arranged at the cleaning port 11, and the stopper 24 is a flange corresponding to the flange, and the two are connected to achieve the stoppage of the cleaning port 11. In some other embodiments, the stopper 24 is a sealing plug with elasticity, which is inserted into the cleaning port 11 to achieve the stoppage of the cleaning port 11.

[0058] In some embodiments, the washing device 3 comprises a stirring mechanism 31 and a brush 32, the stirring mechanism 31 is arranged on the kettle body 1 and is in transmission connection with the brush 32 to drive the brush 32 to rotate, the brush 32 has an end in contact with the inner wall of the kettle body 1, and the stirring mechanism 31 drives the brush 32 to rotate to brush the scale on the inner wall of the kettle body 1. The brush 32 is flexible and will not interfere with the cleaning device 2 when rotating.

[0059] In some embodiments, the kettle body 1 further has a manhole (not shown) which is a hole for people to pass through and is generally used for workers to enter the kettle body 1 for maintenance. The brush 32 is detachably connected with the stirring mechanism 31. It is easy to understand that the high-pressure reaction kettle generally has a stirring mechanism 31 for stirring sulfuric acid and ore pulp during production operation. During the scale removal operation, the original stirring mechanism 31 of the high-pressure reaction kettle can be used to install the brush 32 on the stirring mechanism 31, and the stirring mechanism 31 drives the brush 32 to rotate to remove the scale. After the scale removal is completed, the brush 32 is removed, and the stirring mechanism 31 continues to be used for production stirring.

[0060] In some embodiments, the reaction kettle scale removal system further comprises a plurality of partitions 4 which are arranged in the kettle body 1 and are fixedly connected with the kettle body 1 to divide the kettle body 1 into a plurality of reaction chambers which are in communication with each other, at least one washing device 3 and cleaning port 11 are arranged in each reaction chamber, and each reaction chamber performs the scale removal operation respectively.

[0061] It is noted that in the description of the present specification, the description referring to the terms "some embodiments", "other embodiments", and the like means that the specific features, structures, materials or characteristics described in the embodiments or examples are included in at least one embodiment or example of the present application. In the present specification, the illustrative description of the above terms does not necessarily mean the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0062] The above are only preferred embodiments of the present application and the technical principles applied. Those skilled in the art will understand that the present application is not limited to the specific embodiments described herein, and that various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the scope of the present application. Therefore, although the present application has been described in more detail through the above embodiments, the present application is not limited to the above embodiments, and can include more other equivalent embodiments without departing from the concept of the present application, and the scope of the present application is determined by the scope of the appended claims.
