Description

TECHNICAL FIELD

[0001] The application relates to the technical field of mixing and stirring, and particularly relates to a reaction kettle for chemical raw material production. BACKGROUND

[0002] In the field of chemical raw material production, the reaction kettle as a core equipment undertakes the key link of various chemical reactions. In the esterification reaction process, phosphorus pentasulfide as an important raw material directly affects the efficiency of esterification reaction and product quality due to its uniform dispersion in the reaction system. First, in the esterification stage, phosphorus pentasulfide is prone to sedimentation in the reaction kettle due to its density and physical and chemical properties. This sedimentation breaks the uniform mixing state of the solid-liquid two-phase, causes local concentration difference in the reaction system, affects the sufficiency and consistency of the reaction, and may also cause side reactions, reducing the yield and purity of the target product.

[0003] Secondly, the traditional reaction kettle adopts a stirring mode of one-way rotation of the stirring shaft. In the stirring process, the solution rotates in the same direction as the stirring shaft under the driving of the stirring shaft, forming a single fluid motion trend, and it is difficult to produce sufficient convection and turbulent flow effect, which may cause insufficient contact and mixing between raw materials, prolong the reaction time and reduce the overall production efficiency.

[0004] In addition, in the stirring process, due to factors such as stirring friction heat generation and reaction heat release, the solution in the reaction kettle is prone to overheating. The high temperature not only changes the kinetic characteristics of the chemical reaction, causes the reaction rate to be out of control, but also may damage the chemical structure of the raw materials and products, affect the chemical mixing effect, and even cause safety hazards.

[0038] As Figures 1 to 14 shown, the reaction kettle for chemical raw material production provided by the embodiment of the application comprises a reaction cylinder 110, a turbulence member and a stirring member.

[0039] The reaction cylinder 110 is vertically arranged, the inside of the reaction cylinder 110 is hollow, the cavity in the inside of the reaction cylinder 110 is a reaction cavity 111, the lower end of the reaction cylinder 110 can be placed on the ground or an operating table, the upper end of the reaction cylinder 110 is provided with a mounting opening, the upper end of the reaction cylinder 110 is provided with a blocking cover for blocking the mounting opening, the blocking cover and the reaction cylinder 110 are connected through fixing bolts, so as to ensure that the blocking cover and the reaction cylinder 110 are convenient to disassemble. The blocking cover is provided with a feeding opening 112 penetrating upward and downward, and a worker can feed raw materials into the reaction cavity 111 through the feeding opening 112. The lower end of the reaction cylinder 110 is provided with a discharge opening communicating with the outside environment and the reaction cavity 111, and the reaction cylinder 110 is provided with a blocking plug, which can block the discharge opening. After the mixing of the raw materials is completed, the mixed raw materials can be discharged from the reaction cavity 111 through the discharge opening.

[0040] The reaction cylinder 110 is provided with a heating cavity 120 in the inside of the side wall, and the side wall of the reaction cylinder 110 is provided with a heat supply opening communicating with the heating cavity 120 and the outside environment. A worker can supply a heat source into the heating cavity 120 through the heat supply opening, and the heat carried by the heat source can heat the reaction cavity 111, so as to ensure that the reaction cavity 111 is at a temperature suitable for the mixing of raw materials. Further, the worker can adjust the temperature of the heat source according to the adaptability of the mixed raw materials.

[0041] The turbulence member comprises a plurality of first turbulence rods 130 and a plurality of second turbulence rods 140, the first turbulence rods 130 and the second turbulence rods 140 are both arranged in a spiral shape, the spiral directions of the first turbulence rods 130 and the second turbulence rods 140 are opposite, and the plurality of first turbulence rods 130 and the plurality of second turbulence rods 140 are uniformly arranged on the inside of the side wall of the reaction cylinder 110. Specifically, as shown in the figure, the plurality of first turbulence rods 130 can be divided into four groups, each group comprises a plurality of first turbulence rods 130, and each group of first turbulence rods 130 is arranged in parallel and at intervals in the axial direction of the reaction cylinder 110, and the four groups of first turbulence rods 130 are uniformly distributed around the inside of the side wall of the reaction cylinder 110. Figure 2 As shown in the figure, the plurality of first turbulence rods 130 can be divided into four groups, each group comprises a plurality of first turbulence rods 130, and each group of first turbulence rods 130 is arranged in parallel and at intervals in the axial direction of the reaction cylinder 110, and the four groups of first turbulence rods 130 are uniformly distributed around the inside of the side wall of the reaction cylinder 110. The plurality of second turbulence rods 140 can be divided into four groups, each group comprises a plurality of second turbulence rods 140, and each group of second turbulence rods 140 is arranged in parallel and at intervals in the axial direction of the reaction cylinder 110, and the four groups of second turbulence rods 140 are uniformly distributed around the inside of the side wall of the reaction cylinder 110, and in the circumferential direction of the reaction cylinder 110, each group of second turbulence rods 140 is arranged between two groups of first turbulence rods 130.

[0042] Further, the plurality of first spoiler rods 130 and the plurality of second spoiler rods 140 are hollow inside, and the plurality of first spoiler rods 130 and the plurality of second spoiler rods 140 are in communication with the heating cavity 120. Since the first spoiler rod 130 and the second spoiler rod 140 are arranged inside the reaction cavity 111, when the heating cavity 120 is filled with a heat source, the heat in the heat source is easily transferred to the inside of the heating cavity 120.

[0043] The stirring piece is used to reciprocatingly stir the raw materials in the reaction cavity 111. When the stirring piece reciprocatingly stirs the raw materials in the reaction cavity 111, the movement form of the raw materials in the reaction cavity 111 changes reciprocally, so that the raw materials form convection and turbulent flow effects in the reaction cavity 111, thereby achieving sufficient stirring of the raw materials and accelerating the mixing of the raw materials. During the stirring of the raw materials by the stirring piece, the blocky raw materials will be subjected to centrifugal force and will move along the axis direction of the reaction cylinder 110 under the guidance of the first spoiler rod 130 and the second spoiler rod 140, thereby avoiding the deposition of the blocky raw materials at the bottom of the reaction cylinder 110. The stirring piece can also cool the raw materials during the stirring of the raw materials. If the raw materials generate heat during the mixing, the temperature in the reaction cavity 111 will rise. If the temperature in the reaction cavity 111 is too high, the high temperature will destroy the chemical structure of the raw materials and affect the mixing of the raw materials. At this time, the stirring piece cools the raw materials during the stirring of the raw materials, so as to ensure that the temperature in the reaction cavity 111 is in a suitable state for the mixing of the raw materials, thereby ensuring that the performance of the raw materials remains stable.

[0044] The reaction kettle for producing chemical raw materials of the present application is used to produce chemical raw materials. The raw materials are fed into the reaction cavity 111 through the feeding port 112. In order to accelerate the reaction speed of the chemical raw materials, the heating cavity 120 is arranged in the side wall of the reaction cylinder 110. A heat source is supplied into the heating cavity 120 through the heat supply port, so that the temperature in the reaction cavity 111 is in a suitable temperature range for the mixing of the raw materials. A plurality of first spoiler rods 130 and a plurality of second spoiler rods 140 are arranged in the side wall of the reaction cylinder 110, and the inside of each first spoiler rod 130 and each second spoiler rod 140 is in communication with the heating cavity 120, thereby accelerating the heat transfer from the heating cavity 120 to the reaction cavity 111 and ensuring that the reaction cavity 111 can quickly reach the required temperature.

[0045] Further, the first spoiler rod 130 and the second spoiler rod 140 are arranged in a spiral shape, and the spiral directions of the first spoiler rod 130 and the second spoiler rod 140 are opposite. When the stirring piece reciprocatingly stirs the raw materials in the reaction cavity 111, the movement form of the raw materials in the reaction cavity 111 changes reciprocally, so that the raw materials form convection and turbulent flow effects in the reaction cavity 111, thereby achieving sufficient stirring of the raw materials and accelerating the mixing of the raw materials.

[0046] Further, during the stirring of the raw materials by the stirring member, the blocky raw materials are subjected to centrifugal force, the blocky raw materials contact the outer sidewalls of the first turbulence rod 130 and the second turbulence rod 140, and the blocky raw materials move along the axis direction of the reaction cylinder 110 under the guidance of the first turbulence rod 130 and the second turbulence rod 140, so as to avoid the deposition of the blocky raw materials at the bottom of the reaction cylinder 110. Further, during the stirring of the raw materials, the chemical reaction between the raw materials is likely to cause the temperature in the reaction cavity 111 to rise. Once the temperature in the reaction cavity 111 is too high, the chemical structure of the raw materials will be damaged. In order to prevent the chemical structure of the raw materials from being damaged due to the excessively high temperature, the stirring member cools the raw materials during the stirring of the raw materials, so as to ensure the stability of the performance of the raw materials in the reaction cavity 111, and further improve the production efficiency of the raw materials in the reaction cavity 111.

[0047] In one of the embodiments, the stirring member includes a stirring shaft 210 and a stirring plate 230. The stirring shaft 210 is coaxially arranged with the reaction cylinder 110, and the upper end of the stirring shaft 210 penetrates the blocking cover, so that part of the stirring shaft 210 is located in the reaction cavity 111. The driving motor 220 is fixedly arranged on the reaction cylinder 110, and the power output shaft of the driving motor 220 is fixedly connected with the stirring shaft 210 coaxially. When the driving motor 220 is started, the stirring shaft 210 is driven to rotate by the driving motor 220. The stirring plate 230 is connected with the stirring shaft 210, and the stirring plate 230 is located in the reaction cavity 111. When the stirring shaft 210 rotates, the stirring plate 230 can stir the raw materials in the reaction cavity 111. Further, during the assembly, the blocking cover is detached from the reaction cylinder 110. After the blocking cover, the stirring shaft 210, the stirring plate 230 and the driving motor 220 are connected as a whole, the stirring plate 230 is placed in the reaction cavity 111. By arranging the blocking cover, the stirring shaft 210 and the stirring plate 230 can be conveniently placed in the reaction cavity 111.

[0048] In one of the embodiments, the stirring plate 230 includes a first plate 231, two second plates 232, a third plate 233 and a fourth plate 234. The first plate 231, the two second plates 232, the third plate 233 and the fourth plate 234 are all cuboid in shape, and the widths of the first plate 231, the two second plates 232, the third plate 233 and the fourth plate 234 are the same. One end of the first plate 231 in the width direction is rotationally connected to the stirring shaft 210, and the width direction of the first plate 231 extends along the radial direction of the stirring shaft 210. The first plate 231 is rotationally connected to the stirring shaft 210 by means of a first connecting rod 242. The two second plates 232 are arranged on the first plate 231, and the two second plates 232 are symmetrically arranged on the first plate 231. The two second plates 232 are connected to the first plate 231 by means of a second connecting rod 243. The third plate 233 is arranged on the first plate 231, and the third plate 233 is connected to the first plate 231 by means of a third connecting rod 244. The fourth plate 234 is arranged on the first plate 231, and the fourth plate 234 is connected to the first plate 231 by means of a fourth connecting rod 245. Figure 5The angle shown is an example, the width direction of the first plate 231 is arranged along the radial direction of the stirring shaft 210, the length of the first plate 231 is arranged along the axis direction of the stirring shaft 210, the first plate 231 has a first side wall and a second side wall with relatively large area, the first side wall and the second side wall are the front side wall and the rear side wall of the first plate 231 when the stirring shaft 210 rotates, and the first side wall and the second side wall serve as the meeting surface of the raw materials. Two second plates 232 are arranged on the upper and lower sides of the first plate 231, the two second plates 232 are arranged in the same plane as the first plate 231, and the two second plates 232 are simultaneously connected to the first plate 231. In the initial state, the distance between the first plate 231 and the second plate 232 is in the maximum state. The third plate 233 is connected to one of the second plates 232, and the third plate 233 is arranged in the same plane as the second plate 232. In the initial state, the distance between the third plate 233 and the second plate 232 is equal to the distance between the second plate 232 and the first plate 231. The fourth plate 234 is connected to the other second plate 232, and the fourth plate 234 is arranged in the same plane as the second plate 232. In the initial state, the distance between the fourth plate 234 and the second plate 232 is equal to the distance between the second plate 232 and the first plate 231. The fourth plate 234 is arranged in the direction of sliding connection with the second plate 232. For easy understanding, the fourth plate 234 can be extended in the length direction, so that the length of the fourth plate 234 can be changed. In the initial state, the length of the fourth plate 234 is in the shortest state, and the shortest length of the fourth plate 234 is less than the length of the third plate 233. When the stirring shaft 210 rotates, the first plate 231, the two second plates 232, the third plate 233 and the fourth plate 234 jointly stir the raw materials. Since the length of the third plate 233 is greater than the length of the fourth plate 234, the first plate 231, the two second plates 232, the third plate 233 and the fourth plate 234 deflect as a whole during the stirring of the raw materials by the stirring shaft 210. During the deflection process, the distance between the first plate 231 and the second plate 232 decreases, the distance between the second plate 232 and the third plate 233 decreases, and the distance between the second plate 232 and the fourth plate 234 decreases. At this time, the block-shaped raw materials are prevented from passing through the stirring plate 230, thereby accelerating the stirring of the raw materials.

[0049] If the chemical reaction between the raw materials during the stirring of the raw materials causes the temperature in the reaction cavity 111 to rise, once the temperature in the reaction cavity 111 is too high, the chemical structure of the raw materials will be destroyed. In this embodiment, when the temperature in the reaction cavity 111 is greater than the first preset temperature, which is a default temperature that is too high, the first preset temperature being a reference parameter set by the worker according to the material of the raw materials. At this time, the length of the fourth plate 234 gradually increases to the length of the third plate 233, and when the length of the third plate 233 is equal to the length of the fourth plate 234, at this time the first plate 231, the two second plates 232, the third plate 233 and the fourth plate 234 are deflected again as a whole to the vertical state. During the deflection process, the distance between the first plate 231 and the second plate 232 increases, the distance between the second plate 232 and the third plate 233 increases, and the distance between the second plate 232 and the fourth plate 234 increases, so that the raw materials can smoothly pass through the stirring plate 230, slow down the stirring of the raw materials, and thus slow down the chemical reaction between the raw materials, thereby indirectly reducing the temperature of the reaction cavity 111.

[0050] In one of the embodiments, the stirring shaft 210 is provided with an arc-shaped first guide rail 240 and a second guide rail 250, both of which are arc-shaped and symmetrically arranged about the rotation shaft of the stirring shaft 210 connecting the first plate 231. The first plate 231 is provided with a first sliding block slidingly arranged along the first guide rail 240, and the fourth plate 234 is provided with a second sliding block slidingly arranged along the second guide rail 250. The first guide rail 240 and the second guide rail 250 are provided with a raised position 260 in the middle of the extension direction, and the raised positions 260 of the first guide rail 240 and the second guide rail 250 are symmetrically arranged about the rotation shaft of the stirring shaft 210 connecting the first plate 231. In the initial state, the first sliding block is arranged at the raised position 260 of the first guide rail 240, and the second sliding block is arranged at the raised position 260 of the second guide rail 250, so that the distance between the first plate 231 and the second plate 232 is at the maximum, the distance between the second plate 232 and the third plate 233 is at the maximum, and the distance between the second plate 232 and the fourth plate 234 is at the maximum.
