Description

Technical Field

[0001] The utility model relates to the technical field of silicone oil production, in particular to a silicone oil production material adding device. Background Art

[0002] Silicone oil generally refers to linear polysiloxane products that remain liquid at room temperature. They are generally classified into two categories: methyl silicone oil and modified silicone oil. The most commonly used silicone oil, methyl silicone oil, also known as standard silicone oil, consists entirely of methyl groups. Methyl silicone oil exhibits excellent chemical stability, insulation, and hydrophobic properties. It is produced by hydrolyzing dimethyldichlorosilane with water to produce a primary polycondensation ring. This ring is then cracked and distilled to produce a lower polycondensation ring. The polycondensation ring, a capping agent, and a catalyst are then combined to form a mixture of various polymerization degrees. Low-boiling substances are removed by vacuum distillation to produce the silicone oil.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1

[0021] See also Figure 1-4In this embodiment: a silicone oil production material adding device includes a base 1, a reactor 2 is fixedly installed on the top of the base 1 through a support frame 22, a sealing cover 21 is fixedly installed on the top of the reactor 2, and a symmetrically distributed temporary storage cylinder 6 is fixedly installed on the top of the sealing cover 21. A temporary storage chamber 64 is opened on the inner side of the temporary storage cylinder 6, and a solenoid valve 65 connected to the reactor 2 is installed at the bottom of the temporary storage cylinder 6. A pressure plate 62 is slidably installed on the inner side of the temporary storage chamber 64, and a connecting column 63 is fixedly installed on the top of the pressing plate 62. The top of the connecting column 63 is rotatably connected to an adjusting column 7 threadedly connected to the top of the inner side of the temporary storage cylinder 6. A feeding pipe 5 is plugged into the bottom of the side of the temporary storage cylinder 6. When the solenoid valve 65 is in a closed state, the rotary The button 71 drives the adjusting column 7 to rotate, and the horizontal position of the knob 71 on the scale 61 is observed to set the amount of material to be added in advance. After the adjusting column 7 drives the pressure plate 62 to the set position, the material used for silicone oil production is added to the temporary storage tube 6 through the feed pipe 5. The material is filled up, and then the solenoid valve 65 is opened to allow all the materials in the temporary storage tube 6 to flow into the reactor 2 for reaction. In this way, when silicone oil is produced, the set amount of material added can be temporarily stored in advance. During the reaction, multiple groups of temporary storage tubes 6 are opened at the same time, and mixing can be carried out at the same time. On the one hand, the accuracy of the material addition is guaranteed, and on the other hand, the mixing and reaction of the materials are faster and more thorough. This saves costs while also achieving intuitive visualization of the amount of material added.

[0022] As a preferred embodiment, a scale 61 is fixedly installed on the top of the temporary storage cylinder 6 and on the side of the adjusting column 7, and a knob 71 is fixedly installed on the top of the adjusting column 7, so that the amount of material to be added can be set in advance by comparing the positions of the scale 61 and the knob 71.

[0023] As a preferred embodiment, a storage cylinder 3 is fixedly installed on the top of the base 1 and on the side of the reactor 2, and a liquid pump 4 is fixedly installed on the top of the storage cylinder 3. The end of the feed pipe 5 away from the temporary storage cylinder 6 is connected to the liquid pump 4. When the liquid pump 4 is started, the material stored in the storage cylinder 3 is pumped into the temporary storage cylinder 6 through the feed pipe 5.

[0024] Example 2

[0025] See also Figure 1-4 In this embodiment, a diverter cover 9 is fixedly installed at the bottom of the cover 21, and a plurality of evenly distributed flow holes 91 are opened at the bottom of the diverter cover 9. After the solenoid valve 65 is opened, the materials in the plurality of temporary storage cylinders 6 flow downward at the same time and enter the diverter cover 9, and then flow into the reactor 2 through the flow holes 91. In this way, the materials are mixed in advance in the diverter cover 9, and the diversion through the flow holes 91 further accelerates the mixing and reaction speed of multiple materials in the silicone oil production.

[0026] As a preferred embodiment, a driving motor is fixedly installed inside the cover 21, and a center rod 8 is fixedly installed on the output end of the driving motor. The center rod 8 passes through the diverter cover 9 and extends to the inside of the reactor 2. Stirring rods 81 are fixedly installed on the side of the center rod 8 and below the diverter cover 9 at equal intervals from top to bottom. The driving motor drives the center rod 8 to rotate, so that the stirring rod 81 stirs and mixes the silicone oil production materials. In conjunction with the diverter cover 9, the mixing reaction efficiency of the silicone oil material can be further improved.

[0027] As a preferred embodiment, an internal thread groove is provided on the top of the inner side of the temporary storage tube 6, and an external thread groove that matches the internal thread groove is provided on the outer side of the adjusting column 7. The surface of the adjusting column 7 does not contact the inner side of the temporary storage chamber 64, thereby ensuring the smoothness of the adjustment of the adjusting column 7. At the same time, it also isolates the adjusting column 7 from the silicone oil production material, thereby improving the safety of adding silicone oil material.

[0028] The working principle and use process of the present invention are as follows: the operator rotates the knob 71 to drive the adjustment column 7 to rotate, and adjusts the horizontal position of the knob 71 on the scale 61 to set the amount of material to be added in advance. After the adjustment column 7 drives the pressure plate 62 to the set position, the material used for silicone oil production is added into the temporary storage cylinder 6 through the feeding pipe 5 until it is full. Then, the solenoid valve 65 is opened to allow all the materials in the temporary storage cylinder 6 to flow into the reactor 2 for reaction. In this way, when producing silicone oil, the set amount of material addition can be temporarily stored in advance. During the reaction, multiple groups of temporary storage cylinders 6 are opened at the same time to mix them at the same time. On the one hand, the accuracy of the material addition is ensured, and on the other hand, the mixing and reaction of the materials are faster and more thorough. This saves costs and also realizes the intuitive visualization of the material addition amount. The materials in multiple temporary storage cylinders 6 flow downward at the same time and enter the diverter cover 9. Then, they flow into the reactor 2 through the flow hole 91. In this way, the materials are mixed in advance in the diverter cover 9. The diversion through the flow hole 91 further accelerates the mixing and reaction speed of multiple materials in silicone oil production.
