[0034] As Figures 1 to 3 The present application provides a reaction kettle, and embodiments of the reaction kettle of the present application include: a kettle body 10, a partition plate assembly 20, a feeding part 30, and a discharging part 40; the kettle body 10 has a reaction cavity 11 extending in the transverse direction; the partition plate assembly 20 is arranged in the reaction cavity 11, and the partition plate assembly 20 includes a plurality of partition plates arranged at intervals in the transverse direction, the plurality of partition plates including a first partition plate 21 and a second partition plate 22, the first partition plate 21 having a first flow gap 23 between the first partition plate 21 and the inner wall of the reaction cavity 11, the second partition plate 22 having a second flow gap 24 between the second partition plate 22 and the inner wall of the reaction cavity 11, the first projection of the first flow gap 23 on a preset cross section being completely non-coincident with the second projection of the second flow gap 24 on the preset cross section; the feeding part 30 is arranged on the kettle body 10, the feeding part 30 being in communication with the reaction cavity 11 and being used for inputting materials; the discharging part 40 is arranged on the kettle body 10, the feeding part 30 and the discharging part 40 being located on two sides of the partition plate assembly 20, the discharging part 40 being in communication with the reaction cavity 11 and being used for outputting materials.

[0035] The technical scheme of the embodiment is applied, the kettle body 10 has a reaction cavity 11 extending in the transverse direction; the baffle assembly 20 is arranged in the reaction cavity 11 to separate the reaction cavity 11 into multiple chambers, the baffle assembly 20 includes first and second baffles 21 and 22 arranged in the transverse direction, that is, the chambers are formed between the first and second baffles 21 and 22 or between the first baffle 21 and the inner wall of the reaction cavity 11 or between the second baffle 22 and the inner wall of the reaction cavity 11, the first baffle 21 and the inner wall of the reaction cavity 11 have a first flow gap 23, and the second baffle 22 and the inner wall of the reaction cavity 11 have a second flow gap 24, the first and second flow gaps 23 and 24 are arranged to enable adjacent chambers in the multiple chambers to be communicated, the feeding portion 30 is arranged on the kettle body 10, the feeding portion 30 is communicated with the reaction cavity 11 and is used for inputting materials; the discharging portion 40 is arranged on the kettle body 10, the feeding portion 30 and the discharging portion 40 are located on both sides of the baffle assembly 20, the discharging portion 40 is communicated with the reaction cavity 11 and is used for discharging materials; since the first projection of the first flow gap 23 on a preset cross section and the second projection of the second flow gap 24 on the preset cross section are completely not coincident, assuming that the first baffle 21 is upstream of the second baffle 22, after the mixed materials flow through the first flow gap 23, the mixed materials will not directly flow through the second flow gap 24, but will be blocked by the second baffle 22 to change the flow direction, so that the mixed materials stay in the chamber between the first and second baffles 21 and 22 for a longer time, avoiding the situation that the mixed materials flow through the first flow gap 23 and then directly flow through the second flow gap 24, and thus the mixing and reaction of the materials are better, and vice versa, if the second baffle 22 is upstream of the first baffle 21. Therefore, the technical scheme of the embodiment can effectively solve the problem of insufficient reaction degree in the related art.

[0036] In addition, the solid material in the mixed material can be prevented from depositing at the bottom of the reaction cavity 11, and the mixing reaction can be improved. It should be noted that the first projection and the second projection overlap at a point, and the first projection of the first flow gap 23 on the preset cross section and the second projection of the second flow gap 24 on the preset cross section do not overlap completely. In the embodiment, the preset cross section refers to the cross section of the reaction cavity 11. The feeding part 30 is in communication with the reaction cavity 11 and is used for inputting the material. The feeding part 30 can at least input the first material and the second material into the reaction cavity 11, and other materials can also be inputted, for example, in the embodiment, the first material is a mineral slurry, the second material is sulfuric acid, and in addition to the mineral slurry and the sulfuric acid, steam can also be inputted into the reaction cavity 11. The discharging part 40 is in communication with the reaction cavity 11 and is used for outputting the material. The mixed material can include the first material and the second material, and can also include other materials, and the materials and the materials can generate substances due to the reaction.

[0037] As shown in Figure 2 and Figure 3 , the first projection and the second projection are symmetrically arranged relative to the preset symmetry line, and the preset symmetry line passes through the center of the preset cross section. In the embodiment, the cross section of the reaction cavity 11 is a circular structure, the preset symmetry line extends in the transverse direction, one of the first projection and the second projection is located directly above, and one of the first projection and the second projection is located directly below, that is, one of the first flow gap 23 and the second flow gap 24 is located directly above, and the other of the first flow gap 23 and the second flow gap 24 is located directly below, so that when the mixed material flows between the first baffle 21 and the second baffle 22, it can flow in the vertical direction and flow through the flow gap in the transverse direction, thereby further increasing the residence time of the mixed material.

[0038] As shown in Figure 1 , the first baffle 21 is a plurality of, the second baffle 22 is at least one, and at least one second baffle 22 is arranged between adjacent first baffles 21. More specifically, in the embodiment, the first baffle 21 is a plurality of, the second baffle 22 is a plurality of, and the plurality of first baffles 21 and the plurality of second baffles 22 are arranged alternately. In this way, the mixed material can flow along a S-shaped flow path in the reaction cavity 11, the residence time of the mixed material in the reaction cavity 11 can be significantly increased, and sufficient reaction can be ensured.

[0039] As shown in Figure 1As shown, the first flow gap 23 is located below the second flow gap 24. The reactor also includes a pressure balancing part 50, which includes a connecting pipe 51 and a branch pipe 52. One end of the branch pipe 52 is connected to the connecting pipe 51, and the other end of the branch pipe 52 is connected to the reaction chamber 11. The corresponding reactor body 10 between two adjacent first partitions 21 is connected to the branch pipe 52. Specifically, the reactor in this embodiment is typically used for mineral smelting. The first material is powdered mineral particles, and the second material is sulfuric acid. The powdered mineral particles and sulfuric acid are mixed and reacted. In addition, water vapor needs to be introduced into the reaction chamber 11 to heat the mixture. Since the first flow gap 23 is located at a lower position, water vapor tends to accumulate at the top of the reaction chamber 11 due to its characteristics and cannot flow, resulting in an imbalance of gas pressure in different parts of the reaction chamber 11. The function of the gas pressure balancing part 50 is to balance the gas pressure in the reaction chamber 11. Specifically, there are multiple branch pipes 52, all of which are connected to the connecting pipe 51. A connecting pipe 51 is provided between each pair of adjacent first partitions 21. In this way, the water vapor accumulated at the top of the reaction chamber 11 can flow into the connecting pipe 51, thereby avoiding the phenomenon of pressure imbalance in different parts of the reaction chamber 11. In this embodiment, from upstream to downstream, the first baffle is the first baffle 21, and the last baffle is the second baffle 22. A portion of the branch pipe 52 is connected to the first end of the vessel body 10 and located on the first side of the baffle assembly 20 (i.e., the side of the baffle assembly 20 closer to the upstream side), allowing the chamber corresponding to the feed section 30 to communicate with the connecting pipe 51. Another portion of the branch pipe 52 is connected to the second end of the vessel body 10 and located on the second side of the baffle assembly 20 (i.e., the side of the baffle assembly 20 closer to the downstream side), allowing the chamber corresponding to the discharge section 40 to communicate with the connecting pipe 51. Furthermore, in other embodiments, the vessel body corresponding to two adjacent second baffles is connected to a portion of the branch pipe. In summary, the function of the branch pipe 52 is to connect relatively isolated chambers where gas flow is difficult to achieve to the connecting pipe 51, thereby balancing the gas pressure in these chambers.

[0040] like Figure 1 As shown, the ratio between the distance between adjacent first partitions 21 and second partitions 22 and the dimension of the reaction chamber 11 in the lateral direction is greater than or equal to 1:10 and less than or equal to 1:3. Specifically, this arrangement ensures that the number of chambers formed between two adjacent partitions is within a suitable range, thereby guaranteeing sufficient mixing of the mixture without creating too many chambers; the ratio between the distance between two adjacent partitions and the dimension of the reaction chamber 11 in the lateral direction can be 1:10, 1:9, 1:8, 1:7, 1:6, 1:5, 1:4, or 1:3.

[0041] like Figure 2 as well as Figure 3As shown, the ratio between the area of the first flow gap 23 and the cross-sectional area of the reaction cavity 11 is greater than or equal to 1:100 and less than or equal to 1:2; the ratio between the area of the second flow gap 24 and the cross-sectional area of the reaction cavity 11 is greater than or equal to 1:100 and less than or equal to 1:2. In this way, the first flow gap 23 and the second flow gap 24 are not too small to cause poor flow of the mixed material, and the first flow gap 23 and the second flow gap 24 are not too large to cause insufficient reaction of the mixed material; the ratio between the area of the first flow gap 23 and the cross-sectional area of the reaction cavity 11 can be 1:100, 1:80, 1:75, 1:68, 1:45, 1:21, 1:10 or 1:2; the ratio between the area of the second flow gap 24 and the cross-sectional area of the reaction cavity 11 can be 1:100, 1:80, 1:75, 1:68, 1:45, 1:21, 1:10 or 1:2. It should be noted that the "area of the first flow gap 23" and the "area of the second flow gap 24" refer to the area of the projection of the flow gap on the cross-sectional area of the reaction cavity 11.

[0042] As shown in Figure 1 The reaction kettle further comprises at least one stirring part 60 arranged in the reaction cavity 11, and at least one stirring part 60 is arranged between adjacent baffles. In this way, each chamber has a stirring part 60 for stirring, thereby ensuring the reaction effect of the mixture.

[0043] As shown in Figure 1 The reaction kettle further comprises a feeding part 70 arranged on the reaction kettle corresponding to the baffle assembly 20 and close to the feeding part 30. Specifically, the feeding part 70 is mainly used for supplementing sulfuric acid and water vapor to ensure the normal progress of the mixed reaction. "The feeding part 70 is arranged close to the feeding part 30" means that the distance between the feeding part 70 and the feeding part 30 in the transverse direction is less than the distance between the feeding part 70 and the discharging part 40.

[0044] As shown in Figure 4 and Figure 5 The second embodiment of the reaction kettle is provided, and the difference between the second embodiment and the first embodiment is that the preset symmetry line extends in an oblique direction. "The preset symmetry line extends in an oblique direction" means that the direction in which the preset symmetry line extends is arranged at an angle with the vertical direction and the transverse direction. In this embodiment, the preset symmetry line is arranged at an angle of 45° with the vertical direction and the transverse direction.

[0045] As shown in Figure 6 and Figure 7As shown, the third embodiment of the reaction kettle is provided in the application, and the third embodiment is different from the first embodiment in that the preset symmetry line extends along the vertical direction. In this way, the first flow gap 23 and the second flow gap 24 are located at the front side or the rear side, respectively.

[0046] In the description of the utility model, it is understood that the orientation words such as '' front, rear, upper, lower, left, right '' '' horizontal, vertical, perpendicular, horizontal '' and '' top, bottom '' and the like indicated orientation or positional relationship is usually based on the orientation or positional relationship shown in the drawings, only for the convenience of describing the utility model and simplifying the description, in the absence of the opposite statement, these orientation words do not indicate and imply that the device or element indicated must have a particular orientation or be constructed and operated in a particular orientation, therefore, it cannot be understood as the limitation of the protection scope of the utility model; the orientation words '' inside, outside '' refer to the inside and outside relative to the contour of each component.

[0047] For the convenience of description, spatial relative terms such as '' above'', '' above'', '' upper surface'', '' upper '' and the like can be used here to describe the spatial position relationship of one device or feature with other devices or features as shown in the drawing. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the device described in the drawing. For example, if the device in the drawing is inverted, the device described as '' above '' or '' above '' other devices or structures will be positioned '' below '' or '' below '' other devices or structures. Thus, the example term '' above '' can include both '' above '' and '' below '' orientations. The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative description used here is interpreted accordingly.

[0048] In addition, it should be noted that the use of '' first'', '' second '' and the like to limit parts is only for the convenience of distinguishing the corresponding parts, and the above words have no special meaning unless otherwise stated, therefore, it cannot be understood as the limitation of the protection scope of the utility model.
