Abstract
Description
Cross Reference to Related Application The present disclosure claims benefit of Chinese Patent Application No. 202423316571.4, filed on December 31, 2024, entitled “Reaction Kettle”, the contents of which are hereby incorporated by reference in its entirety. Technical Field The present disclosure relates to the technical field of chemical devices, specifically to a reaction kettle. Background A reaction kettle is a chemical device commonly used for ore smelting. A horizontal reaction kettle is a type of reaction kettle that has a reaction cavity extending along a transverse direction. In related technologies, a reaction cavity of a horizontal reaction kettle is usually provided with a plurality of baffles at intervals along a transverse direction, and the baffles divide the reaction cavity into a plurality of cavities. In a direction from an upstream side to a downstream side (i.e., in a direction from a feeding portion to a discharging portion), the heights of the baffles gradually decrease to allow reaction materials to gradually overflow into the next cavity through the baffle. During the continuous operation of the horizontal reaction kettle, the amount of reaction materials in each cavity is relatively large. In this way, the above reaction materials are prone to entering the cavity at the downstream side after just entering the cavity without sufficient mixing and reaction, resulting in a lower reaction degree of the reaction materials. Therefore, there is a problem of insufficient reaction degree in related fields. Summary A main objective of the present disclosure is to provide a reaction kettle to solve the problem of insufficient reaction degree in related technologies. In order to achieve the above objective, the present disclosure provides a reaction kettle, including: a kettle body including a reaction cavity extending along a transverse direction; a partition assembly arranged in the reaction cavity, wherein the partition assembly includes a plurality of partitions arranged at intervals in the transverse direction, the plurality of partitions include a first partition and a second partition, a first flow passage gap is formed between the first partition and an 2025204824 26 Jun 2025 inner wall of the reaction cavity, a second flow passage gap is formed between the second partition and the inner wall of the reaction cavity, and a first projection of the first flow passage gap on a preset cross section completely does not coincide with a second projection of the second flow passage gap on the preset cross section; a feeding portion arranged on the kettle body, wherein the feeding portion is communicated with the reaction cavity and is configured to feed materials; and a discharging portion arranged on the kettle body, wherein the feeding portion and the discharging portion are located on two sides of the partition assembly, and the discharging portion is communicated with the reaction cavity and is configured to discharge materials. Further, the first projection and the second projection are symmetrically arranged relative to a preset symmetric line, and the preset symmetric line passes through a center of the preset cross section. Further, a plurality of first partitions are provided, at least one second partition is provided, and at least one second partition is arranged between adjacent first partitions of the plurality of first partitions. Further, the preset symmetric line extends along a vertical direction; and / or the preset symmetric line extends along the transverse direction; and / or the preset symmetric line extends along an oblique direction. Further, the first flow passage gap is located below the second flow passage gap, the reaction kettle further includes an air pressure balance portion, the air pressure balance portion includes a communicating pipe and branch pipes, one end of each of the branch pipes is communicated with the communicating pipe, and the other end of each of the branch pipes is communicated with the reaction cavity, wherein a corresponding kettle body between two adjacent first partitions of the plurality of first partitions is connected to a part of the branch pipes; and / or when a plurality of second partitions are provided, a corresponding kettle body between two adjacent second partitions is connected to a part of the branch pipes; and / or a part of the branch pipes is connected to a first end of the kettle body and is located on a first side of the partition assembly; and / or a part of the branch pipes is connected to a second end of the kettle body and is located on a second side of the partition assembly. Further, a ratio of a distance between two adjacent partitions of the plurality of partitions to a size of the reaction cavity in the transverse direction is greater than or equal to 1:10 and less than or equal to 1:3. Further, a cross section of the reaction cavity is of a circular structure. 2025204824 26 Jun 2025 Further, a ratio of an area of the first flow passage gap to an area of a cross section of the reaction cavity is greater than or equal to 1:100 and less than or equal to 1:2; and / or a ratio of an area of the second flow passage gap to an area of a cross section of the reaction cavity is greater than or equal to 1:100 and less than or equal to 1:2. Further, the reaction kettle further includes at least one stirring portion arranged in the reaction cavity, and at least one stirring portion is arranged between two adjacent partitions. Further, the reaction kettle further includes a supplementing portion, and the supplementing portion is arranged on the reaction kettle corresponding to the partition assembly and is close to the feeding portion. By applying the technical solutions of the present disclosure, a kettle body has a reaction cavity extending along a transverse direction. The partition assembly is arranged in the reaction cavity to divide the reaction cavity into a plurality of cavities. The partition assembly includes a first partition and a second partition arranged at intervals in the transverse direction, that is, the cavity is formed between the first partition and the second partition or between the first partition and the inner wall of the reaction cavity or between the second partition and the inner wall of the reaction cavity. A first flow passage gap is formed between the first partition and the inner wall of the reaction cavity, and a second flow passage gap is formed between the second partition and the inner wall of the reaction cavity. By forming the first flow passage gap and the second flow passage gap, adjacent cavities in the plurality of cavities can be communicated.

A discharging portion is arranged on the kettle body, the feeding portion and the discharging portion are located on two sides of the partition assembly, and the discharging portion is communicated with the reaction cavity and is configured to discharge materials. Because a first projection of the first flow passage gap on a preset cross section completely does not coincide with a second projection of the second flow passage gap on the preset cross section, assuming that the first partition is located at the upstream side of the second partition, after the mixed material flows through the first flow passage gap, the mixed material will not directly flow through the second flow passage gap, but will be blocked by the second partition to change the flow direction. In this way, the mixed material stays in the cavity between the first partition and the second partition for a longer period of time to avoid the situation that the mixed material flows through the first flow passage gap and then directly flows through the second flow passage gap, so that the mixing and reaction effects of the material are better. On the contrary, if the second partition is located at the upstream side of the first partition, the situation is the same. Therefore, the technical solutions of the present application can effectively solve the problem of insufficient reaction degree in related technologies. 2025204824 26 Jun 2025 Brief Description of the Drawings The accompanying drawings of the specification that constitute a part of the present application are used to provide a further understanding of the present disclosure.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numbers and letters represent similar items in the following accompanying drawings. Therefore, once a certain item is defined in one accompanying drawing, it does not need to be further discussed in subsequent accompanying drawings. As shown in Fig. 1 to Fig. 3, the present application provides a reaction kettle. An example of a reaction kettle of the present application includes: a kettle body 10, a partition assembly 20, a feeding portion 30, and a discharging portion 40. The kettle body 10 includes a reaction cavity 11 extending along a transverse direction. The partition assembly 20 is arranged in the reaction cavity 11, the partition assembly 20 includes a plurality of partitions arranged at intervals in the transverse direction, the plurality of partitions include a first partition 21 and a second partition 22, a first flow 2025204824 26 Jun 2025 passage gap 23 is formed between the first partition 21 and the inner wall of the reaction cavity 11, a second flow passage gap 24 is formed between the second partition 22 and the inner wall of the reaction cavity 11, and a first projection of the first flow passage gap 23 on a preset cross section completely does not coincide with a second projection of the second flow passage gap 24 on the preset cross section. The feeding portion 30 is arranged on the kettle body 10, and the feeding portion 30 is communicated with the reaction cavity 11 and is configured to feed materials. The discharging portion 40 is arranged on the kettle body 10, the feeding portion 30 and the discharging portion 40 are located on two sides of the partition assembly 20, and the discharging portion 40 is communicated with the reaction cavity 11 and is configured to discharge materials. By applying the technical solution of this example, the kettle body 10 has a reaction cavity 11 extending along a transverse direction. A partition assembly 20 is arranged in the reaction cavity 11 to divide the reaction cavity 11 into a plurality of cavities. The partition assembly 20 includes a first partition 21 and a second partition 22 arranged at intervals in the transverse direction, that is, the cavity is formed between the first partition 21 and the second partition 22 or between the first partition 21 and the inner wall of the reaction cavity 11 or between the second partition 22 and the inner wall of the reaction cavity 11. A first flow passage gap 23 is formed between the first partition 21 and the inner wall of the reaction cavity 11, and a second flow passage gap 24 is formed between the second partition 22 and the inner wall of the reaction cavity 11. By forming the first flow passage gap 23 and the second flow passage gap 24, adjacent cavities in the plurality of cavities can be communicated. A feeding portion 30 is arranged on the kettle body 10, and the feeding portion 30 is communicated with the reaction cavity 11 and is configured to feed materials. A discharging portion 40 is arranged on the kettle body 10, the feeding portion 30 and the discharging portion 40 are located on two sides of the partition assembly 20, and the discharging portion 40 is communicated with the reaction cavity 11 and is configured to discharge materials. Because a first projection of the first flow passage gap 23 on a preset cross section completely does not coincide with a second projection of the second flow passage gap 24 on the preset cross section, assuming that the first partition 21 is located at the upstream side of the second partition 22, after the mixed material flows through the first flow passage gap 23, the mixed material will not directly flow through the second flow passage gap 24, but will be blocked by the second partition 22 to change the flow direction. In this way, the mixed material stays in the cavity between the first partition 21 and the second partition 22 for a longer period of time to avoid the situation that the mixed material flows through the first flow passage gap 23 and then directly flows through the second flow passage gap 24, so that the mixing and reaction effects of the material are better. On the contrary, if the second partition 22 is located at the upstream side of the first partition 21, the situation is the same. 2025204824 26 Jun 2025 Therefore, the technical solution of this example can effectively solve the problem of insufficient reaction degree in related technologies. In addition, this arrangement can also prevent solid materials in the mixed material from depositing at the bottom of the reaction cavity 11, thereby improving the degree of mixing reaction. It should be noted that the situation that the first projection coincides with the second projection at a point also meets the condition that "the first projection of the first flow passage gap 23 on the preset cross section completely does not coincide with the second projection of the second flow passage gap 24 on the preset cross section". In this example, the preset cross section refers to a cross section of the reaction cavity 11. "The feeding portion 30 is communicated with the reaction cavity 11 and is configured to feed materials" refers to: the feeding portion 30 can at least feed a first material and a second material into the reaction cavity 11, and can also feed other materials. For example, in this example, the first material is mineral slurry, and the second material is sulfuric acid. In addition to the mineral slurry and sulfuric acid, steam can also be fed into the reaction cavity 11. "The discharging portion 40 is communicated with the reaction cavity 11 and is configured to discharge materials" refers to: the mixed material can not only include the first material and the second material, but also other materials, as well as substances produced by reactions between materials. As shown in Fig. 2 and Fig. 3, the first projection and the second projection are symmetrically arranged relative to a preset symmetric line, and the preset symmetric line passes through the center of the preset cross section. In this example, the cross section of the reaction cavity 11 is of a circular structure, and the preset symmetric line extends along the transverse direction. One of the first projection and the second projection is located directly above, and the other is located directly below, that is, one of the first flow passage gap 23 and the second flow passage gap 24 is located directly above, and the other is located directly below. In this way, when the mixed material flows between the first partition 21 and the second partition 22, the mixed material can flow along the vertical direction and flow through the flow passage gap in the transverse direction, thereby further prolonging the retention time of the mixed material. As shown in Fig. 1, a plurality of first partitions 21 are provided, at least one second partition 22 is provided, and at least one second partition 22 is arranged between adjacent first partitions 21. More specifically, in this example, a plurality of first partitions 21 are provided, a plurality of second partitions 22 are provided, and the plurality of first partitions 21 and the plurality of second partitions 22 are arranged alternately. By this arrangement, the mixed material can flow along a similar-S-shaped flow path in the reaction cavity 11, thereby significantly prolonging the retention time of the mixed material in the reaction cavity 11 to ensure the sufficient reaction. 2025204824 26 Jun 2025 As shown in Fig. 1, the first flow passage gap 23 is located below the second flow passage gap 24, the reaction kettle further includes an air pressure balance portion 50, the air pressure balance portion 50 includes a communicating pipe 51 and branch pipes 52, one end of each of the branch pipes 52 is communicated with the communicating pipe 51, the other end of each of the branch pipes 52 is communicated with the reaction cavity 11, and the corresponding kettle body 10 between two adjacent first partitions 21 is connected to the branch pipe 52. Specifically, the reaction kettle in this example is usually used for mineral smelting, the first material is powdery mineral particles, the second material is sulfuric acid, and the powdery mineral particles and the sulfuric acid are mixed for reacting. In addition, it is necessary to introduce water vapor into the reaction cavity 11 to heat the mixed material. Due to the lower position of the first flow passage gap 23, the water vapor easily accumulates at the top of the reaction cavity 11 due to the characteristics thereof and cannot flow, resulting in imbalance of the air pressure of each part of the reaction cavity 11. The function of arranging the air pressure balance portion 50 is to balance the air pressure inside the reaction cavity 11. Specifically, a plurality of branch pipes 52 are provided and are all communicated with the communicating pipe 51, and a branch pipe 52 is arranged between every two adjacent first partitions 21. In this way, the water vapor accumulated at the top of the reaction cavity 11 can flow into the communicating pipe 51, thereby avoiding the phenomenon of imbalance of the air pressure of each part of the reaction cavity 11. In this example, in a direction from the upstream side to the downstream side, the initial partition is the first partition 21, and the last partition is the second partition 22. A part of the branch pipes 52 is connected to the first end of the kettle body 10 and located on the first side of the partition assembly 20 (i.e., the side of the partition assembly 20 close to the upstream side), so that the cavity corresponding to the feeding portion 30 is communicated with the communicating pipe 51. A part of the branch pipes 52 is connected to the second end of the kettle body 10 and located on the second side of the partition assembly 20 (i.e., the side of the partition assembly 20 close to the downstream side), so that the cavity corresponding to the discharging portion 40 is communicated with the communicating pipe 51. In addition, in other examples, the corresponding kettle body between two adjacent second partitions is connected to a part of the branch pipes. In short, the function of the branch pipe 52 is to communicate the relatively isolated cavities in which the gas is not easy to circulate with the communicating pipe 51, thereby balancing the air pressure of the cavities. As shown in Fig. 1, the ratio of the distance between the adjacent first partition 21 and second partition 22 to the size of the reaction cavity 11 in the transverse direction is greater than or equal to 1:10 and less than or equal to 1:3. Specifically, by this arrangement, the number of cavities formed between two adjacent partitions is within a relatively appropriate range, thereby ensuring the 2025204824 26 Jun 2025 sufficient mixing of the mixed material without providing too many cavities. The ratio of the distance between two adjacent partitions to the size of the reaction cavity 11 in the transverse direction may be 1:10, 1:9, 1:8, 1:7, 1:6, 1:5, 1:4, or 1:3. As shown in Fig. 2 and Fig. 3, the ratio of the area of the first flow passage gap 23 to the area of the cross section of the reaction cavity 11 is greater than or equal to 1:100 and less than or equal to 1:2; and the ratio of the area of the second flow passage gap 24 to the area of the cross section 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 passage gap 23 and the second flow passage gap 24 cannot be too small to cause poor circulation of the mixed material, and the first flow passage gap 23 and the second flow passage gap 24 cannot be too large to cause insufficient reaction of the mixed material. The ratio of the area of the first flow passage gap 23 to the area of the cross section of the reaction cavity 11 may be 1:100, 1:80, 1:75, 1:68, 1:45, 1:21, 1:10, or 1:2. The ratio of the area of the second flow passage gap 24 to the area of the cross section of the reaction cavity 11 may 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 passage gap 23" and the "area of the second flow passage gap 24" both refer to the area of the projection of the flow passage gap on the cross section of the reaction cavity 11. As shown in Fig. 1, the reaction kettle further includes at least one stirring portion 60 arranged in the reaction cavity 11, and at least one stirring portion 60 is arranged between two adjacent partitions. By this arrangement, each chamber has a stirring portion 60 for stirring, thereby ensuring the reaction effect of the mixture. As shown in Fig. 1, the reaction kettle further includes a supplementing portion 70, and the supplementing portion 70 is arranged on the reaction kettle corresponding to the partition assembly 20 and is close to the feeding portion 30. Specifically, the supplementing portion 70 is mainly configured to supplement sulfuric acid and water vapor to ensure the normal progress of the mixing reaction. "The supplementing portion 70 is close to the feeding portion 30" refers to: in the transverse direction, the distance between the supplementing portion 70 and the feeding portion 30 is less than the distance between the supplementing portion 70 and the discharging portion 40. As shown in Fig. 4 and Fig. 5, the present application further provides a second example of a reaction kettle. The difference between the second example and the first example is: the preset symmetric line extends along an oblique direction. "The preset symmetric line extends along an oblique direction" refers to: an included angle is formed between the extension direction of the preset symmetric line and the vertical direction as well as between the extension direction of the preset symmetric line and the transverse direction. In this example, an included angle of 45° is 2025204824 26 Jun 2025 formed between the preset symmetric line and the vertical direction as well as between the preset symmetric line and the transverse direction. As shown in Fig. 6 and Fig. 7, the present application further provides a third example of a reaction kettle. The difference between the third example and the first example is: the preset symmetric line extends along a vertical direction. In this way, the first flow passage gap 23 and the second flow passage gap 24 are respectively located on the front side or the rear side. In the description of the present disclosure, it should be understood that the orientation or position relationships indicated by orientation words such as "front, rear, up, down, left and right", "transverse, vertical, perpendicular and horizontal", and "top and bottom" are usually based on the orientation or position relationships shown in the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description. Unless otherwise stated, these orientation words do not indicate or imply that the apparatus or component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present disclosure. The orientation words "inside and outside" refer to the inside and outside of the contour relative to each component. For ease of description, spatial relative terms such as "above ...", "over ...", "on an upper surface of ..." and "on the top of ..." can be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to include different orientations in use or operation other than the orientations of the devices described in the figures. For example, if the devices in the accompanying drawings are inverted, the devices described as "over other devices or structures" or "above other devices or structures" will be then positioned as "under other devices or structures" or "below other devices or structures". Therefore, the exemplary term "over ..." may include two orientations: "over ..." and "under ...". The device may also be positioned in other different manners (rotated 90 degrees or in other orientations), and the spatial relative description used here is explained accordingly. In addition, it should be noted that using terms such as "first" and "second" to define parts is only intended to facilitate the differentiation of corresponding parts. Unless otherwise stated, the above terms have no special meanings and therefore cannot be understood as limiting the scope of protection of the present disclosure. The above descriptions are only preferred embodiments of the present disclosure, but are not intended to limit the present disclosure. It will be apparent to those skilled in the art that various 2025204824 26 Jun 2025 modifications and changes can be made in the present disclosure. Any modifications, equivalent substitutions, improvements, and the like made within the spirit and principle of the present disclosure shall be included within the scope of protection of the present disclosure.
