Description

Technical Field

[0001] This utility model relates to the field of propoxy introduction technology in the production of mercaptopropyltriethoxysilane, and particularly to a propoxy introducer for the production of mercaptopropyltriethoxysilane. Background Technology

[0002] Mercaptopropyltriethoxysilane is a sulfur-containing silane, a pale yellow to yellow transparent liquid with an unpleasant sulfide odor. It is insoluble in water but soluble in alcohol. It will slowly undergo a chemical book reaction with water. It is often used to treat inorganic fillers such as silica and carbon black. In polymers such as rubber and silicone rubber, it acts as an activator, coupling agent, crosslinking agent, and reinforcing agent.

[0003] In the production of mercaptopropyltriethoxysilane, sodium hydrosulfide and chloropropyltriethoxysilane are used as raw materials. Under aqueous conditions, a condensation reaction occurs by adding a propoxy phase transfer catalyst. In this process, a propoxy introducer is needed to inject propoxy groups into the container for the production of mercaptopropyltriethoxysilane to participate in the chemical reaction and generate the desired compound.

[0004] Since the inlet is generally an empty and sealed tank, and the inlet itself lacks a pressure control structure and a filtration structure, it cannot filter the propoxy liquid and continuously and stably introduce propoxy into the container for the production of mercaptopropyltriethoxysilane, thus affecting the stability of the reaction effect of mercaptopropyltriethoxysilane raw material inside the container.

[0005] Therefore, it is necessary to provide a propoxy introducer for the production of mercaptopropyltriethoxysilane to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a propoxy introducer for the production of mercaptopropyltriethoxysilane, which solves the problem that the introducer itself lacks a pressure control structure and a filtration structure, which cannot continuously and stably introduce propoxy into the container for the production of mercaptopropyltriethoxysilane, thus affecting the reaction stability of the raw materials in the container. The present invention includes: a mounting base;

[0007] A base frame is fixedly connected to the top of the mounting base. An inlet device is fixedly connected to the base frame. A fixing ring is fixedly connected to one end of the inlet device. A sealing ring is provided at one end of the fixing ring, and a pressure control membrane is installed at the other end of the sealing ring. A top frame is fixedly connected to the top of the outer surface of the inlet device. Multiple liquid inlet pipes are installed on the top of the top frame. A liquid level sensor is installed on the top of the top frame. A filter structure is installed on the top of the top frame.

[0008] A pressure sensor is installed at one end of the inlet, and a telescopic rod is installed at the other end of the inlet via a sealing seat. A connecting bolt is installed at the telescopic end of the telescopic rod. An inlet tube is installed at one end of the inlet near the bottom, and a valve is installed at the other end of the inlet tube. A filter bucket is fixedly connected to the inner surface of the inlet at the top position.

[0009] The pressure-controlled membrane divides the inlet into two chambers. The filter structure is installed on the outer surface of the inlet at the end with the telescopic rod, allowing filtered air to enter the interior of the inlet to assist the pressure-controlled membrane in stabilizing the pressure in the chamber containing propoxy-containing liquid. Both the pressure-controlled membrane and the sealing ring are made of corrosion-resistant materials. The liquid level sensor can monitor the height of the propoxy-containing liquid inside the inlet, and the pressure sensor can monitor the pressure in the chamber containing the propoxy-containing liquid inside the inlet. Together with the control of the telescopic rod, the pressure of the inlet is stabilized, allowing it to continuously and stably introduce propoxy-containing liquid into the mercaptopropyltriethoxysilane production container. Valves are installed on the inlet pipes, and the valves on the inlet pipes are connected to the mercaptopropyltriethoxysilane production container through pipelines.

[0010] Preferably, an equipment box is fixedly connected to the front of the base frame, and an operation screen is mounted on the front of the base frame via a fixed base;

[0011] The control panel can control the operation of the equipment on the base frame, and the equipment box contains power switches and controllers for controlling the operation of the equipment.

[0012] Preferably, a heating device is installed at the bottom of the base frame, and a heating resistor is installed at the top of the heating device;

[0014] Preferably, a drain pipe is fixedly connected to the bottom of the filter bucket, and a threaded cap is threadedly connected to the other end of the drain pipe.

[0015] Preferably, the mounting base includes a base plate, and mounting holes are provided at the top of the base plate near the four corners. Four buffer bolts are fixedly connected to the top of the base plate.

[0016] The top of the buffer bolt is connected to the bottom of the base frame.

[0017] Preferably, the filter structure includes a through pipe, the top end of which is threadedly connected to an exhaust bracket, and a filter disc is mounted inside the exhaust bracket via an mounting ring;

[0018] The filter disc can prevent dust from entering the inside of the inlet.

[0019] To solve the above-mentioned technical problems, this utility model provides a propoxy introducer for the production of mercaptopropyltriethoxysilane.

[0020] Compared with related technologies, the propoxy introducer for the production of mercaptopropyltriethoxysilane provided by this utility model has the following beneficial effects:

[0021] This invention provides a propoxy introducer for the production of mercaptopropyltriethoxysilane. To ensure a continuous and stable introduction of filtered propoxy groups into the mercaptopropyltriethoxysilane production container, a fixing ring is fixedly connected to one end of the introducer. A pressure-controlled membrane is then bolted onto the fixing ring, and a sealing ring is placed between the pressure-controlled membrane and the fixing ring to enhance sealing. The pressure-controlled membrane divides the introducer into two chambers, and the extension and retraction of a telescopic rod drives the movement of the pressure-controlled membrane to balance the pressure in the two chambers. This allows for the production of propoxy groups. To maintain continuity and stability during the base introduction process, a filter funnel is installed inside the introducer, with the funnel and inlet pipe positioned correspondingly. This allows for the filtration of the propoxy-containing liquid entering the introducer before it is introduced into the mercaptopropyltriethoxysilane production vessel. This design enhances the introducer's filtration and pressure control functions, ensuring a continuous and stable introduction of the propoxy-containing liquid into the mercaptopropyltriethoxysilane production vessel. This improves the stability of the raw material reaction during mercaptopropyltriethoxysilane production and increases the quality of mercaptopropyltriethoxysilane production.

[0044] To solve the above-mentioned technical problems, this utility model provides a propoxy introducer for the production of mercaptopropyltriethoxysilane.

[0045] The working principle of the propoxy introducer for the production of mercaptopropyltriethoxysilane provided by this utility model is as follows:

[0046] A fixing ring 23 is fixedly connected to one end of the introducer 6. A pressure-controlling membrane 19 is then bolted onto the fixing ring 23, and a sealing ring 24 is placed between the pressure-controlling membrane 19 and the fixing ring 23 to increase sealing. The pressure-controlling membrane 19 divides the introducer 6 into two chambers, and the extension and retraction of the telescopic rod 17 drives the movement of the pressure-controlling membrane 19 to balance the pressure in the two chambers of the introducer 6, maintaining continuity and stability during propoxy introduction. Simultaneously, a filter funnel 15 is installed inside the introducer 6, with the filter funnel 15 corresponding to the inlet pipe 8. This allows for the filtration of the propoxy liquid entering the introducer 6 before it is introduced into the mercaptopropyltriethoxy liquid. In the mercaptopropyltriethoxysilane production container, during actual use, propoxyl liquid is first transported into the inlet 6 through the inlet pipe 8. During this process, the propoxyl liquid is filtered by the filter bucket 15. Then, the pressure and liquid level inside the inlet 6 are monitored by the pressure sensor 5 and the liquid level sensor 7. After that, the valve 4 on the inlet pipe 3 is opened, and the propoxyl liquid is introduced into the mercaptopropyltriethoxysilane production container through the inlet pipe 3. During this process, the telescopic rod 17 moves slowly in sync with the pressure changes monitored by the pressure sensor 5, so that the chamber containing the propoxyl liquid is maintained at a stable pressure, thereby allowing the propoxyl liquid to be introduced into the mercaptopropyltriethoxysilane production container stably and continuously.

[0047] Compared with related technologies, the propoxy introducer for the production of mercaptopropyltriethoxysilane provided by this utility model has the following beneficial effects:

[0048] To ensure a continuous and stable introduction of filtered propoxy groups into the mercaptopropyltriethoxysilane production container, a retaining ring 23 is fixedly connected to one end of the inlet 6. A pressure-controlled membrane 19 is then bolted onto the retaining ring 23, and a sealing ring 24 is placed between the pressure-controlled membrane 19 and the retaining ring 23 to enhance sealing. The pressure-controlled membrane 19 divides the inlet 6 into two chambers, and the extension and retraction of the telescopic rod 17 moves the pressure-controlled membrane 19 to balance the pressure in the two chambers of the inlet 6. This ensures a stable supply of propoxy groups during the introduction process. To ensure continuity and stability, a filter bucket 15 is installed inside the inlet 6, with the filter bucket 15 corresponding to the liquid inlet pipe 8. This allows the propoxy liquid entering the inlet 6 to be filtered before being introduced into the mercaptopropyltriethoxysilane production container. This design enhances the filtration and pressure control functions of the inlet 6, enabling the propoxy liquid to be filtered and then continuously and stably introduced into the mercaptopropyltriethoxysilane production container. This is beneficial to the stability of the raw material reaction during the mercaptopropyltriethoxysilane production process and increases the quality of mercaptopropyltriethoxysilane production.
