Description

Technical Field

[0001] This utility model relates to the technical field of organosilicon compound synthesis equipment, and in particular to a tert-butyldimethylchlorosilane synthesis device with automatic packaging function. Background Technology

[0002] tert-Butyl dimethylchlorosilane (TBDMSCl) is an important organosilicon protective agent, widely used in pharmaceuticals, pesticides, fine chemicals and other fields. Its synthesis process usually uses dimethylchlorosilane and tert-butyl chloride as raw materials, and generates it through an addition reaction under the action of a catalyst.

[0003] The existing tert-butyldimethylchlorosilane synthesis apparatus has the following problems:

[0004] 1. During the reaction process, when adding raw materials or catalysts to the reaction vessel, the lack of a sealing and protective device will cause the raw materials or catalysts to be directly or indirectly exposed to the air, thereby affecting product quality.

[0005] 2. The lack of coordinated control between systems makes it impossible to monitor key parameters in the production process (such as reaction temperature and filling volume) in real time, which can easily lead to large batch differences in products and poor production stability.

[0006] 3. During the reaction process, excess high-temperature gas will be generated due to the reaction between the raw materials and the catalyst. Although the existing equipment can discharge the excess high-temperature gas, there is no effective way to deal with the sudden pressure increase of the reactor, which poses a huge safety hazard.

[0007] To address the aforementioned issues, we propose a tert-butyldimethylchlorosilane synthesis apparatus with an automated encapsulation function. Utility Model Content

[0008] The purpose of this invention is to provide a tert-butyldimethylchlorosilane synthesis apparatus with automatic packaging function, which aims to solve the technical problems in the prior art.

[0009] To achieve the above objectives, this utility model employs a tert-butyldimethylchlorosilane synthesis apparatus with an automatic packaging function, comprising a synthesis tank. A raw material inlet is provided on one side of the upper part of the synthesis tank, and a catalyst inlet is also provided on one side of the upper part of the synthesis tube. The catalyst inlet is located on the same side as the raw material inlet. One-way valves are respectively provided above the raw material inlet and the catalyst inlet. A main control box is provided on one side of the synthesis tank, and a pressure relief three-way valve is provided on the side of the synthesis tank away from the main control box. A rotating handle is rotatably provided above the pressure relief three-way valve.

[0010] The synthesis tank has a limit frame at its upper center, a motor at its center, a rotating shaft at its lower end, and the end of the rotating shaft away from the motor passes through the synthesis tank and is located inside the lower part of the synthesis tank. A mixing roller is provided on the lower outer surface of the rotating shaft.

[0011] The synthesis tank has a partition plate located above the center of its interior. The partition plate has a cavity at its center for the shaft to pass through. A vent is also provided on one side of the partition plate.

[0012] The synthesis pipe is provided with an exhaust pipe on one side, and a double-pass gas guide pipe is provided on the outer surface of the end of the exhaust pipe away from the synthesis tank.

[0013] The synthesis tank is provided with a discharge pipe at the bottom, and a cooling jacket is provided on the outer surface of the discharge pipe.

[0014] Beneficial effects:

[0015] 1. This utility model discloses a tert-butyldimethylchlorosilane synthesis device with automatic packaging function. The one-way valves at the raw material inlet and catalyst inlet can effectively prevent air from entering the synthesis tank in reverse, avoiding premature contact between the raw material and air to generate impurities. The partition plate inside the synthesis tank, combined with the vent holes, ensures the orderly discharge of reaction gases and reduces the infiltration of external air, thereby reducing the possibility of product moisture absorption and deterioration from the source. When the product is discharged, the cooling jacket on the outer surface of the discharge pipe can quickly cool the high-temperature product to a stable range, avoiding decomposition or side reactions caused by high temperature, further ensuring the quality of the finished product, making the product purity fluctuate less, and effectively solving the pain points of easy product deterioration and large batch differences in the prior art.

[0016] 2. This utility model discloses a tert-butyldimethylchlorosilane synthesis apparatus with automatic packaging function. Addressing the corrosiveness, irritancy, and safety hazards of tert-butyldimethylchlorosilane during the reaction process, the apparatus incorporates a comprehensive protection mechanism. Regarding human contact, the apparatus integrates the synthesis tank with automatic packaging functions. Raw materials are automatically fed via a one-way valve, and the product, after cooling, directly enters the packaging process, significantly reducing manual handling and preventing operators from directly contacting corrosive products, thus reducing the risk of skin burns and respiratory irritation, while also minimizing the risk of human error or misjudgment. For pressure control, a pressure relief three-way valve on the synthesis tank side, coupled with a rotary handle, allows for rapid pressure relief in case of abnormal pressure within the tank.

[0017] 3. The exhaust pipe and dual-way vent pipe can direct harmful gases to the treatment system, preventing gas leaks from endangering personnel and equipment. Furthermore, the central control box enables centralized monitoring and emergency control of parameters such as motor speed and cooling jacket temperature. In case of abnormalities, operators can remotely activate emergency procedures without approaching the danger zone, effectively reducing the risk of direct contact and ensuring operational safety.

Detailed Implementation

[0023] Please see Figure 1 , Figure 1 This is a schematic diagram of the overall structure of this utility model. Figure 2 This is a front view of the entire utility model. Figure 3 This is a utility model Figure 2 The present invention provides a tert-butyldimethylchlorosilane synthesis apparatus with automatic packaging function, as shown in the AA-line structural cross-sectional view. The apparatus includes a synthesis tank 101, a raw material inlet 109 on one side of the upper part of the synthesis tank 101, a catalyst inlet 110 on another side of the upper part of the synthesis tank 101, and the catalyst inlet 110 being located to the side of the raw material inlet 109. One-way valves 111 are respectively installed above the raw material inlet 109 and the catalyst inlet 110. A main control box 108 is located on one side of the synthesis tank 101, and a pressure relief three-way valve 112 is located on the side of the synthesis tank 101 away from the main control box 108. A rotating handle 113 is rotatably mounted above the pressure relief three-way valve 112.

[0024] In this embodiment, the one-way valve 111 prevents air from entering the synthesis tank 101 in reverse during the feeding process, thus preventing the raw materials from contacting air and generating oxidative impurities, ensuring the purity of the raw materials. Simultaneously, the one-way valve 111 blocks the HCl gas generated in the reaction within the synthesis tank 101 from overflowing from the raw material inlet 109 or the catalyst inlet 110, reducing pollution to the operating environment. The centralized control design of the main control box 108 precisely controls the feed rate through preset parameters, avoiding problems of excessive or insufficient raw materials caused by manual operation. The combination of the pressure relief three-way valve 112 and the rotary handle 113 provides a manual emergency pressure relief scheme, mitigating the potential failure risks of the automatic pressure relief system and ensuring rapid handling of abnormal pressure within the synthesis tank 101, preventing damage to the synthesis tank 101 due to overpressure and ensuring equipment safety.

[0025] Furthermore, a limiting frame 102 is provided at the upper center of the synthesis tank 101, a motor 103 is provided at the center of the limiting frame 102, a rotating shaft 104 is provided at the lower end of the motor 103, and one end of the rotating shaft 104 away from the motor 103 passes through the synthesis tank 101 and is located inside the lower part of the synthesis tank 101. A mixing roller 105 is provided on the lower outer surface of the rotating shaft 104.

[0026] In this embodiment, the motor 103 is stably fixed by the limiting frame 102 to prevent the vibration generated by the high-speed operation of the motor 103 from causing the rotating shaft 104 to shift, ensuring that the mixing roller 105 always stirs in the central area of ​​the synthesis tank 101, thus improving the mixing uniformity. The mixing roller 105 adopts a spiral blade structure and acts in the lower part of the synthesis tank 101. Compared with the traditional top stirring paddle, it can effectively avoid the problem of uneven mixing caused by raw materials settling at the bottom of the synthesis tank 101, increasing the contact area between the raw materials and the catalyst by more than 40%, accelerating the reaction rate by 25%, and shortening the reaction cycle. At the same time, the mechanical seal design of the rotating shaft 104 ensures that there is no gas leakage in the synthesis tank 101, further ensuring operational safety.

[0027] Furthermore, the partition plate 106 is provided above the center of the synthesis tank 101, the partition plate 106 has a cavity in the center for the shaft 104 to pass through, and the vent hole 107 is also provided on one side of the interior of the partition plate 106.

[0028] In this embodiment, the initial dispersion effect of the partition plate 106 makes the raw materials fall more evenly, reduces the stirring load of the mixing roller 105, further improves the mixing efficiency, and avoids the problem of intense local reactions caused by concentrated raw materials. The setting of the vent hole 107 ensures that the reaction gas is discharged in an orderly manner, and the metal filter inside the vent hole 107 prevents the raw materials from clogging the pipes, ensuring smooth gas flow. In addition, the partition plate 106 divides the synthesis tank 101 into upper and lower areas, avoiding raw material splashing caused by direct gas impact on the surface of the raw materials, reducing raw material loss, and improving raw material utilization.

[0029] Furthermore, the exhaust pipe 114 is also provided on one side of the synthesis tank 101, and the dual-pass vent pipe 115 is provided on the outer surface of the end of the exhaust pipe 114 away from the synthesis tank 101.

[0030] In this embodiment, the cooperation between the exhaust pipe 114 and the dual-channel duct 115 enables the directional discharge and flexible handling of gas, ensuring that harmful gases are effectively treated while preventing gas leakage and environmental pollution, thus protecting the health of operators.

[0031] Furthermore, the discharge pipe 116 is provided below the synthesis tank 101, and the cooling jacket 117 is provided on the outer surface of the discharge pipe 116.

[0032] In this embodiment, the cooling jacket 117 can quickly cool the high-temperature product to a stable range, preventing the product from decomposing or deteriorating due to high temperature (tert-butyldimethylchlorosilane absorbs moisture at a significantly faster rate when the temperature exceeds 40°C). The remote control of the electric gate valve on the discharge pipe 116 and the real-time monitoring of the temperature sensor on the cooling jacket 117 replace the traditional manual control of discharge and temperature measurement, which not only improves the convenience of operation but also accurately controls the product temperature, avoiding product quality problems caused by human misjudgment. At the same time, the cooled product flows directly from the discharge pipe 116 into the automatic packaging equipment, reducing the manual transfer link and further reducing the risk of product contact with air.

[0033] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
