Description

Technical Field

[0001] The invention relates to the technical field of chemical equipment, and in particular to a material blocking structure and a reaction kettle. Background Art

[0002] High-pressure reactor is the core and heavy equipment in the wet high-pressure leaching process of laterite nickel ore. It is mainly used for high-pressure leaching of nickel and cobalt.

[0003] The interior of the high-pressure reactor is usually divided into multiple compartments, each of which is equipped with a mechanical stirring device to promote the full reaction of the slurry and the acid. Two adjacent compartments are separated by a baffle. The presence of the baffle can increase the shear effect of the fluid during the stirring process. During production, the reactants pass through each compartment in turn. In order to ensure that the reactants can pass through the baffle, openings are provided at the upper and lower ends of the baffle.

[0004] Although the openings at the upper and lower ends of the baffle can facilitate the passage of reactants, the baffle's blocking effect on the fluid is weakened because it affects the shearing effect of the fluid during the stirring process. During the design, if the opening on the baffle is large, it will affect the baffle's blocking effect on the fluid and the pressure leaching efficiency; if the opening on the baffle is small, the rate at which the material passes through the baffle will become lower, which will affect the production efficiency. Therefore, how to improve the baffle's blocking effect on the material without affecting the production efficiency, and improve the stirring effect and pressure leaching efficiency of the high-pressure reactor is a technical problem that needs to be solved urgently.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0033] like Figures 1 to 3 As shown, the present invention discloses a material baffle structure 2, including a fixed baffle 21, a movable baffle 22 and a lifting drive assembly 23, the fixed baffle 21 is provided with a plurality of first through grooves 211 evenly spaced in the vertical direction, the fixed baffle 21 is used to separate and fix between two adjacent isolation material chambers; the movable baffle 22 is arranged in close contact with the fixed baffle 21, and the movable baffle 22 is provided with a plurality of second through grooves 221 corresponding to each of the first through grooves 211 spaced in the vertical direction, the second through grooves 221 can be selectively connected with the first through grooves 211 to connect the two adjacent isolation material chambers; the lifting drive assembly 23 is connected to the movable baffle 22, and the lifting drive assembly 23 is used to drive the movable baffle 22 to move, so that the first through grooves 211 are aligned or staggered with the second through grooves 221, and can convert the connected state and the non-connected state of the two adjacent isolation material chambers.

[0034] The present invention also discloses a reactor, comprising a reactor body 1, a plurality of stirring components 3 and the aforementioned plurality of material blocking structures 2, wherein the inner cavity of the reactor body 1 is divided into a plurality of isolated material cavities along the length direction, and each isolated material cavity is provided with a stirring component 3; a material blocking structure 2 is provided between two adjacent isolated material cavities, and each material blocking structure 2 is arranged in the inner cavity of the reactor body 1 at equal intervals along the length direction of the reactor body 1. It can be understood that the fixed baffle 21 is fixed in the reactor body 1, and the shape of the fixed baffle 21 matches the cross-sectional shape of the inner cavity of the reactor body 1, and the inner cavity of the reactor body 1 can be completely isolated. The reactor is particularly suitable for use as a high-pressure reactor.

[0035] Specifically, a feed port 11 and a discharge port 12 are provided on the kettle body 1. The feed port 11 is located at the first isolation material cavity at the end of the kettle body 1, and the discharge port 12 is located at the last isolation material cavity at the other end of the kettle body 1. A slag discharge port 13 is also provided at the lower end of the kettle body 1 away from the feed port 11. A slag discharge valve is installed on the slag discharge port 13, and the slag discharge valve can be selectively opened and closed to timely remove the sediment at the bottom of the inner cavity of the kettle body 1.

[0036] When the reactor is in use, the material needs to be passed from the feed port 11 into the first isolation chamber in the reactor body 1. At this time, the first through slot 211 of the fixed baffle 21 and the second through slot 221 of the movable baffle 22 are staggered, and the first isolation chamber and the adjacent second isolation chamber are in a non-connected state; the material is stirred by the stirring component 3, and after the stirring reaches a preset time, the movable baffle 22 is driven to move by the lifting drive component 23 to align the first through slot 211 with the second through slot 221. At this time, the first isolation chamber and the adjacent second isolation chamber are in a connected state, and the material in the first isolation chamber enters the second isolation chamber via the first through slot 211 and the second through slot 221; the material is then stirred by the stirring component 3 in the second isolation chamber, and after the stirring reaches a preset time, the material blocking structure 2 between the second isolation chamber and the third isolation chamber is opened to allow the material to enter the third isolation chamber. This operation is repeated so that the material can enter each isolation chamber in turn and be stirred. During stirring, the first through groove 211 and the second through groove 221 are staggered to improve the blocking effect on the material, improve the stirring effect and the pressure leaching efficiency. After the stirring is completed, the movable baffle 22 is driven to move by the lifting drive assembly 23, so that the first through groove 211 and the second through groove 221 are aligned and connected, so that the material can quickly enter the next isolation material chamber. The reactor can stably control the blocking effect on the material through the adjustable material blocking structure 2 without affecting the production efficiency, while improving the stirring effect and the pressure leaching efficiency.

[0037] In one of the embodiments, the material blocking structure 2 also includes a lower limit plate 24 and a lower limit rod 25. The bottom end of the lower limit rod 25 is fixed to the bottom wall of the isolation material chamber, and the lower limit plate 24 is fixed to the lower end of the movable baffle 22. A lower limit hole is provided on the lower limit plate 24, and the lower limit rod 25 is movably placed in the lower limit hole so that the lower limit plate 24 and the lower limit rod 25 are relatively slidably arranged in the vertical direction. The movable baffle 22 can be effectively limited by the cooperation between the lower limit plate 24 and the lower limit rod 25, so that the movable baffle 22 and the fixed baffle 21 can be fitted together, thereby improving the stability of the material blocking structure 2.

[0038] Similarly, the material blocking structure 2 can also include an upper limit plate 26 and an upper limit rod 27. The top end of the upper limit rod 27 is fixed to the top wall of the isolation material chamber, and the upper limit plate 26 is fixed to the upper end of the movable baffle 22. An upper limit hole is opened on the upper limit plate 26, and the upper limit rod 27 is movably placed in the upper limit hole so that the upper limit plate 26 and the upper limit rod 27 are relatively slidably arranged in the vertical direction. The movable baffle 22 can also be effectively limited by the cooperation of the upper limit plate 26 and the upper limit rod 27. The arrangement together with the lower limit plate 24 and the lower limit rod 25 can further ensure the fitting effect of the movable baffle 22 and the fixed baffle 21, thereby ensuring the stability and service life of the material blocking structure 2.

[0039] In one embodiment, an upper limit block is provided at the bottom end of the upper limit rod 27, and when the upper limit plate 26 abuts against the upper limit block, the first through slot 211 is connected to or staggered with the second through slot 221. Alternatively, a lower limit block may be provided at the bottom end of the lower limit rod 25, and it is provided that when the lower limit plate 24 abuts against the lower limit block, the first through slot 211 is just connected to or staggered with the second through slot 221. By providing the upper limit block and the lower limit block, the in-position position for switching between the connected state and the non-connected state can be given, and the auxiliary lifting drive assembly 23 can more accurately and quickly drive the movable baffle 22 to the position, so as to improve the work efficiency.

[0040] Optionally, the lifting drive assembly 23 is connected to the upper limit plate 26 , and the lifting drive assembly 23 can move the movable baffle 22 more smoothly by driving the upper limit plate 26 to slide back and forth in the vertical direction.

[0041] Specifically, the lifting drive assembly 23 includes a lifting rod 231, a lower mounting plate 232, an upper mounting plate 233, a column 234, a sleeve 235, a screw rod 236, a threaded sleeve 237 and a rotating drive member 238. The two ends of the column 234 are respectively fixedly connected to the lower mounting plate 232 and the upper mounting plate 233, wherein the lower mounting plate 232 can be selected to be fixedly installed on the top of the kettle body 1; the sleeve 235 is slidably mounted outside the column 234, the screw rod 236 is parallel to the column 234 and is vertically arranged, and the two ends of the screw rod 236 are respectively connected to the lower mounting plate 232 and the upper mounting plate 233. The mounting plate 232 and the upper mounting plate 233 are rotatably connected, and the threaded sleeve 237 is sleeved outside the screw rod 236, and can move up and down following the rotation of the screw rod 236; the rotating driving member 238 is fixedly connected to the screw rod 236, and the rotating driving member 238 is used to drive the screw rod 236 to rotate; the lifting rod 231 is slidably penetrated through the top wall of the isolation material chamber, the lower end of the lifting rod 231 is fixedly connected to the upper limit plate 26, the upper end of the lifting rod 231 passes through the isolation material chamber, and the upper end of the lifting rod 231 is fixedly connected to the threaded sleeve 237 and the sliding sleeve 235.

[0042] In this embodiment, a through hole is opened on the top surface of the kettle body 1, and the lifting rod 231 is slidably penetrated in the through hole. When in use, the rotating driving member 238 drives the screw rod 236 to rotate. When the screw rod 236 rotates, it acts on the threaded sleeve 237. At the same time, the threaded sleeve 237 is limited by the sliding sleeve 235 and cannot rotate. Therefore, the rotation of the screw rod 236 is converted into the up and down movement of the threaded sleeve 237. The threaded sleeve 237 drives the lifting rod 231 to move up and down, thereby driving the upper limit plate 26 and the movable baffle 22 to move up and down.

[0043] See also Figure 3 The threaded sleeve 237 is fixedly connected to the lifting rod 231 via the first connecting rod 2311; the threaded sleeve 237 is also fixedly connected to the sliding sleeve 235 via the second connecting rod 2351 to form a stable connecting rod structure.

[0044] In one embodiment, the rotation driving member 238 includes a rotation driving motor 2381, a driving gear 2382 and a driven gear 2383. The housing of the rotation driving motor 2381 can be fixedly mounted on the lower mounting plate 232 or the upper mounting plate 233, as long as it is relatively stationary with the kettle body 1 and does not interfere with the movement of the first connecting rod 2311, the second connecting rod 2351 and the lifting rod 231. The driving gear 2382 is coaxially fixed to the output shaft of the rotation driving motor 2381, and the driven gear 2383 is coaxially fixed to the screw rod 236. The driven gear 2383 is meshed with the driving gear 2382 for transmission. When in use, the rotation driving motor 2381 drives the driving gear 2382 to rotate together, and the driving gear 2382 and the driven gear 2383 are transmitted, so that the driven gear 2383 can drive the screw rod 236 to rotate together.

[0045] Exemplarily, the stirring assembly 3 includes a stirring shaft 31, a stirring blade 32 and a stirring motor 33. The stirring shaft 31 is rotatably arranged in the kettle body 1, the stirring blade 32 is fixed to the stirring shaft 31, and the stirring motor 33 is connected to the stirring shaft 31 to drive the stirring shaft 31 to rotate. Among them, the shape and height of the stirring blade 32 need to be able to fully stir the materials in the kettle body 1, and can be set with reference to the prior art. This is not the focus of this embodiment and will not be repeated here.

[0046] In one embodiment, the reactor is a horizontal reactor, and the end of the reactor body 1 along the length direction is set to be arc-shaped. To prevent the material from not being able to flow and stir sufficiently, a plurality of baffles 14 are set at the arc-shaped part of the inner cavity of the reactor body 1. The baffles 14 can be used to turn the material back and improve the stirring effect. Alternatively, the reactor can be applied to other reactors with similar problems, and baffles 14 can also be set at their special-shaped positions to optimize the overall working effect of the reactor.
