Description

Technical Field

[0001] This utility model relates to the field of citral technology, specifically to a continuous reaction synthesis furnace for citral. Background Technology

[0002] Citral is a colorless or slightly yellow oily liquid with a strong lemon aroma. It is sparingly soluble in water but readily soluble in organic solvents such as ethanol and ether. Its chemical structure contains one aldehyde group and two carbon-carbon double bonds, and it exists in two geometric isomers: cis (neraldehyde) and trans (geranialdehyde). Natural citral is usually a mixture of these two isomers.

[0003] In the preparation of citral, two raw materials need to be mixed. To improve mixing efficiency, the raw materials are placed inside a synthesis furnace. After heating and processing in the synthesis furnace, citral can be prepared. Usually, when preparing citral in a synthesis furnace, a certain amount of citral raw material needs to be added sequentially. After the synthesis of citral is completed, the synthesized citral is removed. By repeating this process, the quality of citral can be achieved. However, the continuity of the citral preparation process is poor, and it is impossible to control the synthesis furnace to continuously synthesize the raw materials, resulting in low citral synthesis efficiency. Therefore, we propose a continuous reaction synthesis furnace for citral. Utility Model Content

[0004] To address the shortcomings of existing continuous reaction synthesis furnaces for citral, this invention provides a continuous reaction synthesis furnace for citral that, when the sealing sleeve rotates, aligns the feed inlet with the feed trough inside the mounting tank, allowing for the timely and quantitative feeding of citral raw materials. Simultaneously, as the rotating seat rotates, the synthesized citral is discharged at regular intervals, thereby improving the synthesis efficiency of citral and solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a continuous reaction synthesis furnace for citral, comprising a reactor, a first cover plate installed on the upper end of the reactor via a connecting plate, a first mixing chamber and a second mixing chamber sequentially installed on the upper part of the first cover plate, a second cover plate sleeved on the upper part of the second mixing chamber, a stirring rod installed inside the second cover plate, a sealing sleeve installed at the lower end of the stirring rod via a speed reduction process, an inlet opening inside the sealing sleeve, an installation groove at the bottom end of the second mixing chamber, a conveying pipe fixedly connected inside the first mixing chamber, a rotating seat movably sleeved inside the reactor, and a motor installed at the lower end of the rotating seat.

[0006] Preferably, a bracket is fixedly connected to the outside of the first cover plate, and the bracket is sleeved on the outside of the first mixing tank.

[0007] Preferably, the conveying pipes are arranged in an S-shape, and both ends of the conveying pipes are connected to the mounting groove and the first cover plate in sequence.

[0008] Preferably, the mounting groove has an inlet groove inside, the sealing sleeve is movably fitted inside the mounting groove, and the inlet port is aligned with the inlet groove.

[0009] Preferably, the rotating seat has a discharge hole on its side, and a discharge pipe is fixedly connected to one side of the lower part of the reactor. The discharge hole and the discharge pipe are aligned and installed with each other.

[0010] Preferably, a vertical rod is fixedly connected to the upper part of the rotating seat, and the rotating seat is fitted and installed against the inner wall of the reactor.

[0011] Preferably, the first mixing box and the second mixing box are stacked on top of each other, and the upper sides of the second cover plate are equipped with inlets.

[0012] Compared with existing continuous reaction synthesis furnaces for citral, this invention has the following advantages:

[0013] 1. In this continuous reaction synthesis furnace for citral, the raw material for citral production is fed into the interior of the second cover plate and simultaneously transported to the interior of the second mixing chamber. At the same time, the stirring rod drives the raw material to be stirred inside the second mixing chamber, ensuring that the raw material is fully mixed. This also prevents insufficient mixing of raw materials from affecting the synthesis effect during subsequent continuous synthesis of citral.

[0014] 2. This continuous reaction synthesis furnace for citral uses a stirring rod to drive the sealing sleeve to rotate. After the sealing sleeve controls the alignment of the feed inlet with the feed trough, the initially stirred raw materials are sequentially and quantitatively added into the furnace. At the same time, the raw materials react and synthesize inside the furnace. As the rotating seat rotates, it aligns the discharge hole and discharge pipe, ensuring that the synthesized raw materials are quantitatively discharged. This prevents excessive raw material addition during citral synthesis, thus avoiding exceeding the furnace's load and improving the safety and sufficiency of citral synthesis.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A continuous reaction synthesis furnace for citral includes a reactor 1. A first cover plate 2 is installed on the upper end of the reactor 1 via a connecting plate 3, sealing the upper part of the reactor 1 to maintain a sealed state during raw material synthesis. A first mixing chamber 4 and a second mixing chamber 5 are sequentially installed on the upper part of the first cover plate 2. The second mixing chamber 5 drives the raw materials to mix and stir. A second cover plate 7 is fitted onto the upper part of the second mixing chamber 5. A stirring rod 8 is installed inside the second cover plate 7, driving the raw materials to stir. A sealing sleeve 9 is installed at the lower end of the stirring rod 8 after a speed reduction process. The first mixing chamber 4 has an inlet 10. After the sealing sleeve 9 rotates to control the alignment of the inlet 10 with the mounting groove 11, it can drive the quantitatively mixed raw materials to be transported into the interior of the reactor 1. The bottom of the second mixing chamber 5 has a mounting groove 11. The interior of the first mixing chamber 4 is fixedly connected to a conveying pipe 12, which drives the raw materials to be guided and transported. The interior of the reactor 1 is movably fitted with a rotating seat 13. The lower end of the rotating seat 13 is equipped with a motor 15. When started, the motor 15 and the vertical rod 14 drive the rotating seat 13 to rotate. The rotating seat 13 controls the vertical rod 14 to stir the raw materials, thereby improving the completeness of the raw material reaction and synthesis.

[0023] Please see Figure 1 A bracket 6 is fixedly connected to the outside of the first cover plate 2. The bracket 6 is sleeved on the outside of the first mixing box 4. The bracket 6 is fixedly connected to the outside of the first cover plate 2 and sleeved on the outside of the first mixing box 4, which controls the stability of the first mixing box 4 at the upper end of the first cover plate 2.

[0024] Please see Figure 2 The conveying pipe 12 is arranged in an S-shape, and its two ends are connected to the mounting groove 11 and the first cover plate 2 in sequence. The conveying pipe 12 is installed inside the first mixing box 4 and is located between the mounting groove 11 and the first cover plate 2. When the raw material is conveyed downward through the mounting groove 11, it is conveyed to the inside of the reactor 1 through the conveying pipe 12. The S-shape of the conveying pipe 12 can improve the allowance time for the raw material to be conveyed and avoid direct discharge into the inside of the reactor 1. When the equipment inside the reactor 1 is heating and mixing, the steam generated by heating flows back to the inside of the second mixing box 5 through the conveying pipe 12.

[0025] Please see Figure 5 The installation groove 11 has an inlet groove inside. The sealing sleeve 9 is movably fitted inside the installation groove 11. The inlet 10 is aligned with the inlet groove. The stirring rod 8 is started and drives the raw materials to mix. The sealing sleeve 9 is driven to rotate at a reduced speed through the reduction gear. After the inlet 10 is aligned with the inlet groove, the raw materials mixed inside the first mixing box 4 can be conveyed downward. During the continuous rotation of the sealing sleeve 9, the raw materials are quantitatively added in sequence, which improves the convenience of raw material addition and the uniformity of mixing between raw materials.

[0026] Please see Figure 4 The rotating seat 13 has a discharge hole 16 on its side. A discharge pipe 17 is fixedly connected to one side of the lower part of the reactor 1. The discharge hole 16 and the discharge pipe 17 are aligned with each other. The rotating seat 13 rotates to drive the vertical rod 14 to mix the materials and stir. When the discharge hole 16 and the discharge pipe 17 are aligned, the quantitatively mixed citral can be discharged.

[0027] Please see Figure 4 A vertical rod 14 is fixedly connected to the upper part of the rotating seat 13. The rotating seat 13 is fitted to the inner wall of the reactor 1. The vertical rod 14 is installed on the upper part of the rotating seat 13. During the rotation of the rotating seat 13, the vertical rod 14 mixes the raw materials to ensure that the citral synthesis reaction is stirred, thereby improving the efficiency of citral synthesis.

[0028] Please see Figure 2 The first mixing box 4 and the second mixing box 5 are stacked on top of each other. The upper sides of the second cover plate 7 are equipped with inlets. The second cover plate 7 is installed on the upper part of the second mixing box 5, and the upper part of the second cover plate 7 is equipped with inlets. Through the inlets, raw materials can be continuously fed in, improving the continuity of citral synthesis.

[0029] Working materials: During use, the synthetic raw materials are fed into the second mixing chamber 5 through the second cover plate 7. The stirring rod 8 is started, and the stirring rod 8 stirs the raw materials. The stirring rod 8 drives the sealing sleeve 9 to rotate through the reduction gear. The sealing sleeve 9 drives the inlet 10 to rotate inside the mounting groove 11. When the inlet 10 is aligned with the inlet groove opened inside the mounting groove 11, the initially mixed raw materials are conveyed into the conveying pipe 12. The conveying pipe 12 carries the raw materials to the reactor 1 through buffer conveying. That is, during the rotation of the sealing sleeve 9 driven by the stirring rod 8, the raw materials can be sequentially and quantitatively fed in. The mixing time of the raw materials is provided to avoid incompletely mixed materials being transported into the reactor 1, which would affect the reaction synthesis effect. At the same time, the rotating seat 13 and the heating device are started. The rotating seat 13 drives the raw materials to run and stir through the vertical rod 14, which improves the completeness of the circular reaction. At the same time, when the rotating seat 13 drives the discharge hole 16 to align with the discharge pipe 17, the synthesized citral is discharged through the discharge pipe 17. Therefore, the installation tank 11 quantitatively drives the stirred raw materials to be transported into the reactor 1, and the reactor 1 drives the quantitatively synthesized raw materials to be discharged through the discharge pipe 17, which improves the continuity and completeness of the raw material synthesis.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the material and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
