Description

Technical Field

[0001] This utility model relates to the field of organosilicon oil production technology, and in particular to a device for continuous removal of low molecular weight organosilicon oil. Background Technology

[0002] In the production process of silicone oil, removing low-molecular-weight substances is a crucial step in ensuring product quality and performance. The presence of low-molecular-weight substances affects key indicators of silicone oil, such as viscosity, thermal stability, and chemical stability. If these substances are not effectively removed, silicone oil products will experience performance degradation and shortened service life in application scenarios.

[0003] Existing silicone oil de-molecular weight removal devices mostly adopt intermittent production methods. On the one hand, intermittent operation makes the production process discontinuous, and frequent start-up and shutdown operations not only reduce production efficiency but also increase energy consumption and labor costs. On the other hand, it is difficult to accurately control the feeding speed and flow rate during the feeding process. Often, feeding too fast will result in insufficient de-molecular weight removal of the silicone oil in the de-molecular weight removal tank, or feeding too slow will cause the equipment to be idle and the production efficiency to be low. Therefore, we propose a continuous silicone oil de-molecular weight removal device to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a device for continuous removal of low molecular weight silicone oil to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A continuous de-molecular weight removal device for silicone oil includes: a base plate, a feed tank, a de-molecular weight removal tank, and a collection tank. A support is fixedly installed on the top of the base plate, and a pump body is installed on the top of the support. A discharge pipe connects the bottom of the feed tank to the feed end of the pump body. A conveying pipe connects the top of the de-molecular weight removal tank to the discharge end of the pump body. A connecting pipe (first connection) connects to the top of the de-molecular weight removal tank, and a connecting pipe (second connection) connects to the top of the collection tank. A condenser pipe connects the first and second connecting pipes. The de-molecular weight removal tank contains multiple layers of heating coils and baffles. A drive motor is fixedly installed on the top of the collection tank. A stirring shaft is fixedly installed on the output end of the drive motor. Multiple sets of stirring blades are fixedly installed on the outer side of the stirring shaft. Valve pipes are installed at the bottom of both the de-molecular weight removal tank and the collection tank. Screws are threadedly connected to the bottom of both sets of valve pipes. Valve bodies are fixedly installed on the top of both sets of screws. Turntables are fixedly installed at the bottom of both sets of screws. Discharge pipes are connected to the outer side of both sets of valve pipes.

[0006] Preferably, the bottom of the feed tank, the dewatering tank, and the collection tank are all provided with support legs, and multiple sets of the support legs are arranged on the base plate.

[0007] Preferably, the two sets of valve bodies are rotatably mounted on the inner wall of the corresponding valve pipe, and the two sets of valve bodies are adapted to the suction pipe.

[0008] Preferably, multiple sets of the stirring blades are arranged inside the collection tank.

[0009] Preferably, the liquid inlet of the condenser is connected to one end of the connecting pipe one, and the liquid outlet of the condenser is connected to one end of the connecting pipe two.

[0010] Preferably, the top of the feed tank is connected to a feed inlet.

[0011] In this invention, the continuous de-molecularization device for silicone oil involves depositing the de-molecularized silicone oil at the bottom of a de-molecularization tank. A rotating turntable drives a screw to rotate, which is threaded onto a valve pipe. As the screw rotates, it moves up and down, causing the valve body fixed to the top of the screw to rotate, opening the valve body and allowing the silicone oil to be discharged from the valve pipe through a discharge pipe. A collection tank receives the de-molecularized silicone oil. A drive motor at the top of the collection tank drives a stirring shaft to rotate, causing multiple sets of stirring blades on the shaft to rotate and stir the silicone oil entering the collection tank, ensuring uniform mixing and product quality. The valve pipe and discharge pipe at the bottom of the collection tank have similar structures to the de-molecularization tank. After the silicone oil is uniformly stirred, rotating the turntable opens the valve body, allowing the silicone oil to be discharged through the discharge pipe for further processing or packaging. This meets high-quality production requirements, improves product qualification rate and stability, allows for flexible adjustment of discharge time and quantity, avoids affecting the production process due to excessively fast or slow discharge, and enhances the controllability of production operations. This utility model features a reasonable structural design. During use, silicone oil enters the feed tank through the inlet at the top and is stored there. The pump body is activated to deliver the silicone oil from the outlet pipe to the pump body, which then pumps it through the delivery pipe to the descaling tank, completing the feeding process. The pump body can control the flow rate and speed of the silicone oil. After entering the descaling tank, the heating coils inside heat the silicone oil, causing it to reach a higher temperature and promoting the volatilization of low-molecular-weight substances. Baffles are staggered within the descaling tank, causing the silicone oil to flow in a tortuous pattern under the obstruction and guidance of the baffles, extending its residence time and ensuring full contact between the silicone oil and the heating coils. The heating process ensures uniform heating, thereby more effectively removing low-molecular-weight substances. The volatile low-molecular-weight substances rise and enter the condenser through the connecting pipe at the top of the descaling tank. The low-molecular-weight substances are cooled in the condenser, changing from a gaseous state to a liquid state. The condensed low-molecular-weight liquid flows into the collection tank through the connecting pipe for storage and collection. This achieves the separation and recovery of low-molecular-weight substances, avoiding their discharge into the environment and preventing pollution. It also avoids insufficient treatment in the descaling tank due to excessively fast feeding or reduced production efficiency due to excessively slow feeding. This enables the continuous descaling device for silicone oil to achieve efficient and orderly continuous production, ensuring that the low-molecular-weight substance content in the produced silicone oil product meets the standards and improving product quality.

Discharge pipes 13 are connected to the outside of both sets of valve pipes 9.

[0016] In this embodiment, the bottom of the feed tank 2, the de-sinking tank 8 and the collection tank 17 are all provided with support legs 21. Multiple sets of support legs 21 are set on the base plate 1, which improves the flexibility of device installation.

[0017] In this embodiment, two sets of valve bodies 10 are rotatably installed on the inner wall of the corresponding valve pipe 9. The two sets of valve bodies 10 are compatible with the suction pipe, ensuring the safety of the production process and preventing the leakage of hazardous materials from causing harm to the operators.

[0018] In this embodiment, multiple sets of stirring blades 20 are arranged inside the collection tank 17 to ensure the stability and reliability of product quality.

[0019] In this embodiment, the liquid inlet of the condenser tube 15 is connected to one end of the connecting pipe 14, and the liquid outlet of the condenser tube 15 is connected to one end of the connecting pipe 16, thus ensuring the high efficiency of the condensation and collection process.

[0020] In this embodiment, the top of the feed tank 2 is connected to the feed inlet 3 to ensure the quality of the organosilicon oil raw material and provide a good foundation for the subsequent de-low molecular weight treatment.

[0021] In this embodiment, during use, silicone oil enters the feed tank 2 through the feed inlet 3 at the top of the feed tank 2 for storage. The pump body 6 is started to transport the silicone oil from the discharge pipe 4 to the pump body 6, and then the pump body 6 pumps the silicone oil through the conveying pipe 7 to the descaling tank 8, completing the feeding process. The pump body 6 can control the flow rate and speed of the silicone oil. After the silicone oil enters the descaling tank 8, the heating coil 23 inside the descaling tank 8 heats the silicone oil, causing it to rise in temperature and promoting the volatilization of low-molecular-weight substances. Baffles 22 are staggered inside the descaling tank 8, and the silicone oil is blocked by the baffles 22.

This guarantees uniform heating and more effectively removes low molecular weight substances. The volatile low molecular weight substances move upward and enter the condenser 15 through the connecting pipe 14 at the top of the descaling tank 8. The low molecular weight substances are cooled in the condenser 15, changing from a gaseous state to a liquid state. The condensed low molecular weight liquid flows into the collection tank 17 through the connecting pipe 16 for storage and collection, thus achieving the separation and recovery of low molecular weight substances and preventing them from being discharged into the environment and causing pollution. After the de-molecular treatment, the silicone oil is deposited at the bottom of the de-molecular tank 8. By rotating the turntable 12, the screw 11 is driven to rotate. The screw 11 is threadedly connected to the valve pipe 9. When the screw 11 rotates, it will move up and down, thereby driving the valve body 10 fixed at the top of the screw 11 to rotate, so that the valve body 10 is opened and the silicone oil is discharged from the valve pipe 9 through the discharge pipe 13. The collection tank 17 is used to receive the de-saturated silicone oil product. The drive motor 18 at the top of the collection tank 17 drives the stirring shaft 19 to rotate. The multiple sets of stirring blades 20 on the stirring shaft 19 rotate accordingly to stir the silicone oil entering the collection tank 17, so that the silicone oil is mixed evenly and the product quality is guaranteed. The valve pipe 9 and the discharge pipe 13 at the bottom of the collection tank 17 have similar structures to the de-saturation tank 8. After the silicone oil is stirred evenly, the valve body 10 is opened by rotating the turntable 12, and the silicone oil is discharged through the discharge pipe 13 for further processing or packaging.
