[0002] Dibenzyl ether, also known as benzyl ether, is used as a toughening agent for nitrocellulose and a solvent in fragrance formulation. It can also be used as a moderate antioxidant, primarily in the manufacture of sponge rubber products. It is used as a plasticizer for nitrocellulose and cellulose acetate, and as a solvent for resins, rubbers, waxes, and artificial musk. A mixture of dibenzyl ether and zinc oxide is used as a repellent for mosquitoes, flies, midges, and fleas.

[0003] Chinese patent document CN222943484U discloses a synthesis reactor, including a reactor body. A top cover is fixedly installed on the top of the reactor body. A motor is fixedly installed at the center of the top of the top cover. A rotating shaft is rotatably installed at the center inside the top cover.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0014] Compared with the prior art, the present invention has the following beneficial effects:

A support mechanism 2 is fixedly connected to the lower part of the outer surface of the reactor body 1, which can support and fix the reactor body 1. A discharge pipe 3 is fixedly connected to the bottom of the outer surface of the reactor body 1. A solenoid valve 31 is installed and fixedly installed in the inner cavity of the discharge pipe 3. A limiting mechanism 4 is fixedly connected to the upper part of the outer surface of the reactor body 1, which can lock and limit the installation position of the sealing mechanism 5. The sealing mechanism 5 is movably connected to the upper part of the outer surface of the reactor body 1, which can seal the upper opening end of the reactor body 1. The lower side of the sealing mechanism 5 is threadedly connected to the inner part of the limiting mechanism 4. A servo motor 6 is fixedly installed at the middle position of the upper side of the sealing mechanism 5. A stirring mechanism 7 is fixedly connected to the lower output end of the servo motor 6, which can fully stir the raw materials fed into the inner cavity of the reactor body 1. A venting component 8 is fixedly connected to the upper left side of the sealing mechanism 5, which can release the gas generated in the inner cavity of the reactor body 1 during processing.

[0024] To achieve the purpose of supporting and fixing the reactor body 1, refer to... Figure 2 The support mechanism 2 includes a ring frame 21, and a number of support legs 22 are fixedly connected to the lower end of the outer surface of the ring frame 21 in a ring array, which can realize the function of stabilizing the reactor body 1.

[0025] To achieve the purpose of clamping and limiting the installation position of the sealing mechanism 5, refer to... Figure 2 The limiting mechanism 4 includes a fixed base 41, and an internally threaded sleeve 42 is fixedly connected to the upper end of the outer surface of the fixed base 41, which can lock the position of the externally threaded sleeve 52 through the threaded connection.

[0026] To achieve the purpose of sealing the upper opening of the reactor body 1, please refer to... Figure 3 The sealing mechanism 5 includes a sealing cover 51, and an external threaded sleeve 52 is fixedly connected to the outer side of the lower end of the outer surface of the sealing cover 51. The outer surface of the external threaded sleeve 52 is threadedly connected to the inner surface of the internal threaded sleeve 42.

[0027] By rotating the sealing cover 51, the external threaded sleeve 52 and the inner wall of the internal threaded sleeve 42 are driven by threaded transmission, so that the sealing cover 51 can be firmly installed and clamped on the upper part of the outer surface of the reactor body 1, thereby ensuring the airtightness between the upper opening end of the reactor body 1 and the lower end of the sealing cover 51.

[0028] To ensure thorough mixing of the raw materials fed into the inner cavity of reactor body 1, please refer to... Figure 3The stirring mechanism 7 includes a rotating shaft 71, and a number of stirring plates 72 are fixedly connected to the outer surface of the rotating shaft 71 in a ring array. It can achieve the function of fully stirring raw materials and catalysts under the drive of the servo motor 6. The upper end of the outer surface of the rotating shaft 71 is fixedly connected to the lower output end of the servo motor 6.

[0029] To achieve the purpose of venting the gases generated during the processing of the inner cavity of the reactor body 1, see [reference needed]. Figure 4 The ventilation component 8 includes a ventilation pipe 81. Several guide grooves 82 are arranged in an annular array on the upper part of the outer surface of the ventilation pipe 81. A receiving cavity 83 is provided at the upper end of the outer surface of the ventilation pipe 81. A reset component 84 is fixedly connected to the bottom wall of the inner cavity of the receiving cavity 83, which can facilitate the reset of the position of the exhaust end cover 85. An exhaust end cover 85 is slidably connected to the upper part of the outer surface of the ventilation pipe 81. Several exhaust ports 86 are arranged in an annular array on the side wall of the outer surface of the exhaust end cover 85. A receiving cavity 87 is provided on the top wall of the inner cavity of the exhaust end cover 85.

[0030] To facilitate the repositioning of the exhaust end cap 85, please refer to... Figure 4 The reset assembly 84 includes two annular connecting plates 841. The outer surfaces of the two annular connecting plates 841 are close to each other and are fixedly connected to a rust-proof spring 842. The lower end of the outer surface of the lower annular connecting plate 841 is fixedly connected to the bottom wall of the inner cavity of the first receiving cavity 83, and the upper end of the outer surface of the upper annular connecting plate 841 is fixedly connected to the top wall of the inner cavity of the second receiving cavity 87.

[0031] When a large amount of heat is generated in the inner cavity of the reactor body 1 during processing, the gas pressure in the inner cavity increases significantly. When the gas pressure in the inner cavity of the reactor body 1 rises to a predetermined value, the gas pressure will push the exhaust end cover 85 to slide upward along the inner cavity of several guide grooves 82. At this time, several exhaust ports 86 will be connected to the upper opening end of the vent pipe 81, so that the heat in the inner cavity of the reactor body 1 can be smoothly discharged outward along the inner cavity of the vent pipe 81 through several exhaust ports 86. When the gas pressure in the inner cavity of the reactor body 1 drops to a certain value, that is, when the gas pressure in the inner cavity of the reactor body 1 is lower than the rebound force of the anti-rust spring 842, the rebound force of the anti-rust spring 842 will pull the exhaust end cover 85 downward until the exhaust end cover 85 is completely fitted onto the upper end of the outer surface of the vent pipe 81 again, so that the opening end of several exhaust ports 86 is sealed by the side wall of the outer surface of the vent pipe 81, thereby sealing the heat in the inner cavity of the reactor body 1.

[0032] It should be noted that the servo motor 6 in this utility model is a Siemens 1FT7, and the solenoid valve 31 is a DSG-02. The specific installation method, circuit connection method and control method of the servo motor 6 and the solenoid valve 31 are all conventional designs, and this utility model will not elaborate on them in detail.

[0033] The working principle of this invention is as follows: After all the catalyst raw materials, such as benzyl alcohol and benzoic anhydride, are added into the inner cavity of the reactor body 1, the external threaded sleeve 52 is rotated along the inner cavity of the internal threaded sleeve 42 and locked onto the upper side of the reactor body 1 by holding the sealing cap 51. Then, the servo motor 6 is turned on, causing the rotating shaft 71 to start rotating, thereby allowing the stirring plates 72 to fully stir the raw materials in the inner cavity of the reactor body 1. During the stirring, the raw materials undergo a chemical reaction and generate a large amount of gas. When the gas pressure in the inner cavity of the reactor body 1 reaches a predetermined value, the gas pressure will push upward. The exhaust end cover 85 slides upward along the outer surface of the vent pipe 81. At the same time, the upward sliding exhaust end cover 85 will pull the anti-rust spring 842 to undergo elastic deformation. When the exhaust end cover 85 rises, the opening ends of several exhaust ports 86 will connect with the upper opening end of the vent pipe 81, so that the gas in the inner cavity of the reactor body 1 can be smoothly discharged outward. When the gas pressure in the inner cavity of the reactor body 1 is less than the elastic force of the anti-rust spring 842, the rebound force of the anti-rust spring 842 will pull the exhaust end cover 85 downward to reset to the initial position, thereby sealing the inner cavity of the reactor body 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
