Description

Technical Field

[0001] This utility model relates to the field of silane coupling agent synthesis technology, specifically a constant temperature device for silane coupling agent synthesis. Background Technology

[0002] Silane coupling agents were first used in fiberglass as surface treatment agents for glass fibers, which greatly improved the mechanical, electrical, and anti-aging properties of fiberglass. Their importance in the fiberglass industry has long been recognized. With the continuous development of technology, the application of silane coupling agents has expanded from glass fiber reinforced plastics to surface treatment agents for glass fiber reinforced thermoplastics, surface treatment agents for inorganic fillers, and other surface treatment agents. During the synthesis of silane coupling agents, it is necessary to control the synthesis temperature of the raw materials, but the temperature control performance of existing constant temperature devices is insufficient.

[0003] In the existing synthesis process of silane coupling agents, raw materials need to be supplied to the reactor through a pipe valve structure. However, the gas generated during the reaction can enter the pipeline through the pipe opening and flow into the raw material tank, causing the raw materials to react. Utility Model Content

[0004] The purpose of this invention is to provide a constant temperature device for the synthesis of silane coupling agents. When the liquid raw material enters the pipe through the feeding valve, the raw material diffuses and flows from the top of the valve ball to its surroundings. It flows into the bottom of the valve ball through the gap between the valve ball and the ball screen. The valve ball is suspended inside the valve ball under the interaction of the liquid pressure above and the buoyancy at the bottom. When the feeding stops, the valve ball falls and blocks the screen groove, which can prevent gas from flowing back from the inside of the screen groove into the pipe and solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a constant temperature device for the synthesis of silane coupling agents, comprising a reactor, a top cover being provided on the top of the reactor, a steam coil being provided on the outside of the reactor, wherein an angle bracket is provided above the steam coil and the angle bracket is connected to the reactor by bolts, a pipe shaft is provided above the top cover, a motor assembly is provided on the top of the pipe shaft, a locking cover, a feeding valve pipe and a pressure relief valve pipe are provided around the surface of the top cover, and a bottom drain pipe is provided at the bottom of the reactor.

[0006] Furthermore, a connecting rod is provided inside the reactor, and a drive rod is provided above the connecting rod. The drive rod is connected to the connecting rod by bolts, and the drive rod extends into the tube shaft and is rotatably connected to the motor assembly.

[0007] Furthermore, a bottom scraper is provided at the bottom of the connecting rod, and the bottom scraper is connected to the connecting rod by screws. A stirring blade is provided above the bottom scraper.

[0008] Furthermore, the lock cover is provided with latches on all four sides, and the latches are rotatably connected to the lock cover.

[0009] Furthermore, a through pipe is provided at the bottom of the feed valve pipe, which extends into the interior of the reactor, wherein a ball screen is provided at the bottom of the through pipe.

[0010] Furthermore, the ball screen has a screen groove at its bottom and a valve ball inside, wherein the valve ball is configured as a teardrop shape.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, the feed valve pipe for conveying raw materials extends into the reactor through the bottom pipe. At the same time, the liquid level inside the reactor must not exceed the position of the ball screen at the bottom of the pipe. When the liquid raw material enters the pipe through the feed valve pipe, the raw material diffuses from the top of the valve ball to its surroundings and flows into the bottom of the valve ball through the gap between the valve ball and the ball screen. The valve ball is suspended inside the valve ball under the interaction of the liquid pressure above and the buoyancy at the bottom. After the feeding stops, the valve ball falls and blocks the screen groove, which can prevent gas from flowing back into the pipeline from the inside of the screen groove.

[0013] 2. In this utility model, one end of the steam coil is connected to the steam equipment. The steam coil is wrapped around the outside of the reactor. The steam can heat the reactor as it passes through the steam coil, thereby maintaining a constant temperature inside the reactor. The reactor is equipped with a temperature sensing module, which can monitor the internal temperature in real time and regulate the steam supply. Attached Figure Description

[0018] 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.

[0019] To address the issue in existing silane coupling agent synthesis processes where raw materials are supplied to the reactor via a pipe-valve structure, but the gases generated during the reaction can enter the pipeline through the inlet and flow into the raw material tank, causing the raw materials to react; please refer to... Figure 1-3 The present invention provides the following solution:

[0020] A constant temperature device for the synthesis of silane coupling agent includes a reactor 1. The top of the reactor 1 is provided with a top cover 101. A steam coil 2 is provided on the outside of the reactor 1. An angle bracket 102 is provided above the steam coil 2 and is connected to the reactor 1 by bolts. A pipe shaft 301 is provided above the top cover 101. A motor assembly 3 is provided on the top of the pipe shaft 301. Locking caps 103, feeding valve pipes 104 and pressure relief valve pipes 105 are provided around the surface of the top cover 101. A bottom drain pipe 106 is provided at the bottom of the reactor 1.

[0021] In this embodiment, one end of the steam coil 2 is connected to a steam device. The steam coil 2 surrounds the outside of the reactor 1. The steam can heat the reactor 1 as it passes through the steam coil 2, thereby maintaining a constant temperature inside the reactor 1. The reactor 1 is equipped with a temperature sensing module, which can monitor the internal temperature in real time and regulate the steam supply.

[0022] The reactor 1 is equipped with a connecting rod 3021 inside, and a drive rod 302 is provided above the connecting rod 3021. The drive rod 302 is connected to the connecting rod 3021 by bolts. The drive rod 302 extends into the tube shaft 301 and is rotatably connected to the motor assembly 3. A bottom scraper 3023 is provided at the bottom of the connecting rod 3021. The bottom scraper 3023 is connected to the connecting rod 3021 by screws. A stirring blade 3022 is provided above the bottom scraper 3023.

[0023] In this embodiment, the bottom scraper 3023 is located at the bottom of the connecting rod 3021. While playing a stirring role, it can also scrape off the solid raw materials that are stuck and deposited at the bottom of the reactor 1 from the inner wall, so as to avoid the incomplete reaction of the raw materials. The stirring blade 3022 installed above the bottom scraper 3023 can quickly disperse the raw materials that enter the cavity and make them quickly fuse and react through centrifugal force.

[0024] Locking buckles 1031 are provided around the locking cover 103. The locking buckles 1031 are rotatably connected to the locking cover 103. A through pipe 1041 is provided at the bottom of the feeding valve pipe 104. The through pipe 1041 extends into the interior of the reactor 1. A ball screen 1042 is provided at the bottom of the through pipe 1041. A screen groove 1043 is provided at the bottom of the ball screen 1042. A valve ball 1044 is provided inside the ball screen 1042. The valve ball 1044 is designed with a teardrop shape.

[0025] In this embodiment, the feed valve pipe 104 for conveying raw materials extends into the reactor 1 via the bottom through pipe 1041. At the same time, the liquid level inside the reactor 1 must not exceed the position of the ball screen 1042 at the bottom of the through pipe 1041. When the liquid raw material enters the through pipe 1041 through the feed valve pipe 104, the raw material diffuses from the top of the valve ball 1044 to its surroundings. It flows into the bottom of the valve ball 1044 through the gap between the valve ball 1044 and the ball screen 1042. The valve ball 1044 is suspended inside the valve ball 1044 under the interaction of the liquid pressure above and the buoyancy at the bottom. After the feeding stops, the valve ball 1044 falls and blocks the screen groove 1043, which can prevent gas from flowing back into the pipeline from inside the screen groove 1043.

[0026] Working principle: When liquid raw materials enter the through pipe 1041 through the feed valve pipe 104, the raw materials diffuse from the top of the valve ball 1044 to its surroundings. They flow into the bottom of the valve ball 1044 through the gap between the valve ball 1044 and the ball screen 1042. The valve ball 1044 is suspended in the pipe under the interaction of the liquid pressure above and the buoyancy at the bottom. After the feed stops, the valve ball 1044 falls and blocks the screen groove 1043, which can prevent gas from flowing back into the pipe from the inside of the screen groove 1043. Then, the motor drives the connecting rod 3021 to rotate. The bottom scraper 3023 is located at the bottom of the connecting rod 3021. While playing a stirring role, it can also scrape off the solid raw materials that are stuck and deposited at the bottom of the reactor 1 from the inner wall, so as to avoid the incomplete reaction of the raw materials. The stirring blade 3022 installed above the bottom scraper 3023 can quickly disperse the raw materials entering the cavity and make them quickly fuse and react through centrifugal force.
