Description

Technical Field

[0001] This invention belongs to the field of reaction apparatus, specifically relating to a reaction apparatus for synthesizing polyoxymethylene dialkyl ethers. Background Technology

[0002] Polyoxymethylene dialkyl ethers (PODEs) are excellent fuel quality improvers and alternatives. They can significantly improve fuel quality, enhance fuel combustion characteristics, and drastically reduce fuel exhaust emissions. Moreover, they offer unparalleled advantages over conventional fuels in harsh environments such as high altitudes and low oxygen levels.

[0003] However, in actual reaction processes, some components of polyoxymethylene dialkyl ethers adhere to the inner wall of the reaction vessel, making it difficult to mix the components uniformly and affecting the reaction quality. Furthermore, the synthesis of polyoxymethylene dialkyl ethers involves multiple reactions, including the decomposition of paraformaldehyde (trioxymethylene), the condensation of formaldehyde with alcohols, and the growth of polyoxymethylene dialkyl ether chains. During the reaction, an oil-water mixture of solid catalyst particles and ultrafine powder suspensions is generated. After use, a large amount of impurities adhere to the inner wall of the reaction vessel, requiring workers to clean it. This not only increases the workload of workers but also results in poor cleaning effectiveness, potentially affecting reuse. Therefore, a reaction apparatus for synthesizing polyoxymethylene dialkyl ethers is proposed to solve the aforementioned problems. Utility Model Content

[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 1-3 In this embodiment, the reaction apparatus for synthesizing polyoxymethylene dialkyl ethers can reciprocate to scrape off some of the components adhering to the inner wall of the tank 1 through the scraping component 6, so that they can be fully mixed and avoid problems with the reaction quality. After the reaction is completed, the polyoxymethylene dialkyl ethers can be discharged by opening the discharge valve 3. At this time, the scraping component 6 can also scrape off the residue on the inner wall of the tank 1, so as to avoid the residue affecting the next processing and reduce the manual labor pressure.

[0023] Specifically, it includes a tank body 1 and a cover body 2. The cover body 2 and the tank body 1 are detachably connected by bolts, and the bottom of the tank body 1 is conical.

[0024] Discharge valve 3 is connected to the bottom of tank 1;

[0025] The support plate 4 is installed in the lower part of the inner cavity of the tank body 1;

[0026] Two stirring rods 5 are rotatably mounted on the support plate 4, and the upper end of the stirring rods 5 penetrates the cover 2;

[0027] The scraping component 6 is located in the middle of the support plate 4 and penetrates through the cover 2, and is used to clean the residue on the inner wall of the tank 1;

[0028] The power mechanism 7 is installed on the cover 2. The power mechanism 7 is connected to the two stirring rods 5 and the scraping assembly 6 respectively, and is used to provide power to the stirring rods 5 and the scraping assembly 6.

[0029] Feed pipe 8 is connected to the upper part of the outer wall of tank 1.

[0030] In this embodiment, when needed, the components of the external polyoxymethylene dialkyl ether are poured into the tank 1 through the feed pipe 8. Then, the power mechanism 7 is energized and drives the stirring rod 5 and the scraping component 6 in sequence. The stirring rod 5 can fully mix the components in the tank 1 to complete the reaction process, while the scraping component 6 can reciprocate to scrape off some of the components adhering to the inner wall of the tank 1, so that they can be fully mixed and avoid problems with the reaction quality. After the reaction is completed, the polyoxymethylene dialkyl ether can be discharged by opening the discharge valve 3. At this time, the scraping component 6 can also scrape off the residue on the inner wall of the tank 1 to avoid the residue affecting the next processing and reduce the manual labor pressure.

[0031] Specifically, refer to Figure 2-3 The scraping assembly 6 includes a reciprocating screw 61, the bottom end of which is rotatably mounted on the bearing plate 4 and the top end of which penetrates the cover 2; a reciprocating slider 62 sleeved on the outer wall of the reciprocating screw 61; a support frame 63 mounted on the reciprocating slider 62; and an annular scraper block 64 sleeved on the outer wall of the support frame 63.

[0032] In this embodiment, when the reciprocating screw 61 is driven to rotate, the reciprocating slider 62 can drive the support frame 63 and the annular scraper 64 to move up and down through the threaded engagement between the reciprocating screw 61 and the reciprocating slider 62. The annular scraper 64 scrapes the inner wall of the tank 1, thus removing the residue on the inner wall of the tank 1, preventing the components from sticking to the inner wall of the tank 1 and affecting the reaction. The inner wall of the tank 1 can also be cleaned after the reaction is completed.

[0033] Specifically, refer to Figure 2 The power mechanism 7 includes three gears 71, which are rotatably mounted on the top of the cover 2. The three gears 71 are arranged in a row and adjacent gears 71 mesh with each other. A servo motor 72 is mounted on the top of the cover 2. The two ends of the middle gear 71 are connected to the stirring rod 5 and the output end of the servo motor 72, respectively. Four transmission wheels 73 are mounted on the top of two gears 71 and two stirring rods 5, respectively. The two transmission wheels 73 are connected to each other by a transmission belt 74.

[0034] In this embodiment, when the servo motor 72 is powered on, it can sequentially drive the three gears 71 and the reciprocating lead screw 61 to rotate and two of the transmission wheels 73 to rotate. The two transmission wheels 73 drive the other two transmission wheels 73 and the stirring rod 5 to rotate through the transmission belt 74. The stirring rod 5 can stir the components in the tank 1 to make the components uniformly mixed in order to complete the reaction process.

[0035] Specifically, refer to Figure 2-3 Two limiting rods 9 are provided between the bearing plate 4 and the cover 2, and the reciprocating slider 62 is slidably sleeved on the outer wall of the two limiting rods 9.

[0036] In this embodiment, when the reciprocating slider 62 is driven by the reciprocating lead screw 61, the limiting rod 9 can limit and guide the reciprocating slider 62 to prevent the reciprocating slider 62 from rotating with the reciprocating lead screw 61 without reciprocating up and down, thus affecting its use.
