Description

Technical Field

[0001] The utility model mainly relates to the technical field of chemical engineering, and particularly relates to a methyl carbamate synthesis device. Background Art

[0002] Carbamate compounds have a wide range of uses and can be used as intermediates for pesticides, pharmaceuticals, and organic synthesis, etc. Among them, methyl carbamate is a typical carbamate compound. Methyl carbamate, abbreviated as MC, has a molecular weight of 75.07, alias urethane, methyl urethane, white crystalline granules, is easily soluble in water and alcohol. Methyl carbamate can be used for mothproofing fabrics and has good application prospects. It is odorless, has a moderate volatility, low toxicity, and good mothproofing effect, superior to mothproofing agents such as refined naphthalene, p-dichlorobenzene, and trioxymethylene, and is one of the more ideal varieties to replace camphor. In addition, methyl carbamate also has good applications in other insecticides, acaricides, and fungicides, with a variety of varieties and good drug effects.

[0003] The inventor found the following defects during the operation of specific embodiments:

[0004] When synthesizing methyl carbamate using methanol and urea, the traditional synthesis method will generate high-temperature and high-pressure gas-liquid mixed impurities inside the synthesis device. This part of the high temperature needs to be released in time to ensure the smooth progress of the reaction. At the initial and final stages of the release of high-temperature and high-pressure impurities, the flow rate of high-temperature and high-pressure gases is relatively large. When these gases pass through the steel pipe, they will splash out the high-temperature and high-pressure impurities closely accompanying them from the steel pipe and directly spray them around the steel pipe, seriously affecting the personal safety of the staff around the steel pipe.

Inside the outer frame 2, a synthesis tank 3 is installed. On one side of the top of the synthesis tank 3, a feed pipe 4 passing through the top wall of the outer frame 2 is connected. The feed pipe 4 can allow synthesis raw materials to enter the inside of the synthesis tank 3. A stirring mechanism is provided inside the synthesis tank 3. The synthesis raw materials are injected into the inside of the synthesis tank 3 through the feed pipe 4, and the raw materials are stirred by the stirring mechanism for processing and synthesis. Symmetrically connected to the bottom of both sides of the synthesis tank 3 are discharge pipes 5. Symmetrically arranged at the bottom of both sides of the outer frame 2 are cooling boxes 6 that can move horizontally. One end of the discharge pipe 5 passes through the inside of the inner side of the outer frame 2 and can be inserted into the inside of the cooling box 6. Inside the cooling box 6, a rotatable cooling column 7 is provided. On the outer periphery of the cooling column 7, a cooling and cleaning mechanism is provided. Both the cooling and cleaning mechanism and the cooling column 7 are driven by a first motor 8. On one side of the bottom wall of the cooling box 6, a discharge port 601 is opened.

[0028] In this embodiment, the first motor 8 is installed in the middle of the top wall of the cooling box 6. The output end of the first motor 8 is connected to a rotating shaft 9, and the bottom end of the rotating shaft 9 is connected to the top surface of the cooling column 7.

[0029] It should be noted that when the first motor 8 is started to drive the rotating shaft 9 to rotate, the rotating shaft 9 drives the cooling column 7 to rotate. A resin layer is provided on the outer side wall of the cooling column 7. Then, high-temperature impurities are sprayed on different surfaces of the cooling column 7, and the resin layer is used to directly contact the high-temperature impurities, expanding the contact range with the high-temperature impurities and improving the cooling efficiency of the high-temperature impurities.

[0030] In this embodiment, the cooling and cleaning mechanism further includes a water tank 19, which is installed inside the cooling box 6. A water pump 20 is installed on the top of the water tank 19. The output end of the water pump 20 is connected with a hose. A fixing frame 21 is arranged on the outer periphery of the cooling column 7. A water spraying pipe 22 is connected to the inner side wall of the fixing frame 21. The top end of the hose is communicated with the inside of the water spraying pipe 22. A plurality of water spraying openings 2201 are uniformly arranged on the side wall of the water spraying pipe 22.

[0031] It should be noted that the water pump 20 extracts the cleaning water inside the water tank 19 and conveys it to the water spraying pipe 22 through the hose. Finally, it is sprayed on the cooling column 7 through a number of water spraying openings 2201, realizing the cleaning and cooling of the cooling column 7, accelerating the cooling speed of the high-temperature impurities. After the cooling is completed, the impurities are discharged through the discharge port 601.

Both ends of the bottom of the moving seat 26 are connected with sliders that slide inside the slideways 101.

[0033] It should be noted that when high-temperature impurities need to be released inside the synthesis tank 3, the second motor 25 is started to drive the screw rod 23 to rotate. The screw rod 23 drives the two moving seats 26 to approach each other. At the same time, the moving seat 26 also moves horizontally on the cross bar 24. The two moving seats 26 drive the two cooling boxes 6 to approach each other until the extended end of the discharge pipe 5 is inserted into the inside of the cooling box 6. The discharged high-temperature impurities are sprayed on the outer side wall of the cooling column 7 through the discharge pipe 5.

[0034] Working principle of the utility model: The synthetic raw materials are injected into the interior of the synthesis tank 3 through the feed pipe 4, and the raw materials are stirred by the stirring mechanism for processing and synthesis. When high-temperature impurities need to be released inside the synthesis tank 3, the second motor 25 is started to drive the screw 23 to rotate. The screw 23 drives the two moving seats 26 to approach each other. At the same time, the moving seats 26 also move horizontally on the cross bar 24. The two moving seats 26 drive the two cooling boxes 6 to approach each other until the extended end of the discharge pipe 5 is inserted into the interior of the cooling box 6. The discharged high-temperature impurities are sprayed on the outer side wall of the cooling column 7 through the discharge pipe 5. Then, the first motor 8 is started to drive the rotating shaft 9 to rotate. The rotating shaft 9 drives the cooling column 7 to rotate, thereby spraying the high-temperature impurities on different surfaces of the cooling column 7, expanding the contact range with the high-temperature impurities. The water pump 20 pumps the cleaning water inside the water tank 19 and conveys it to the water spraying pipe 22 through the hose. Finally, it is sprayed on the cooling column 7 through a number of water spraying ports 2201, realizing the cleaning and cooling of the cooling column 7, accelerating the cooling speed of the high-temperature impurities. After the cooling is completed, the impurities are discharged through the discharge port 601.

[0035] The above embodiments only represent certain implementation manners of the utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
