Description

Technical Field

[0001] This utility model relates to the technical field of silicone oil filtration equipment, and in particular to a filtration device for vinyl silicone oil. Background Technology

[0002] The production of vinyl silicone oil mainly involves a polymerization reaction of octamethylcyclotetrasiloxane and other compounds with a suitable catalyst, followed by the addition of vinyltrimethoxysilane for end-capping. The purpose of end-capping is to introduce vinyl functional groups at both ends of the vinyl silicone oil molecule, giving it good reactivity and facilitating subsequent cross-linking and curing. End-capping is typically carried out under mild conditions. After the reaction, neutralization and filtration are required to remove reaction residues (including unreacted raw materials and oligomers) to obtain the preliminary vinyl silicone oil product. In existing technologies, vinyl silicone oil is usually filtered through a filter tank. For example, Chinese patent CN202221368398.0 discloses a "vinyl silicone oil cost filter tank". This technology mainly provides a structure that facilitates cleaning the filter screen inside the filter tank. It is an improvement project of our company's previous generation of equipment. After long-term use, it was found that the equipment still has shortcomings: 1. It is difficult to thoroughly clean the impurities on the filter screen by simply rotating the flip seat to remove impurities; 2. After rotating the flip seat, it is necessary to manually shake the flip seat by hand to clean the filter screen, which is laborious and has low cleaning efficiency. Utility Model Content

[0005] Furthermore, the vibration support assembly includes a support column fixedly installed on the outer wall of the filter tank, a spring groove is provided at the top of the support column, and a compression spring and a vibration plate are installed sequentially from the bottom to the opening of the spring groove.

[0006] Furthermore, the vibrating plate is L-shaped.

[0007] Furthermore, the angle between the support column and the vertical direction is 15° to 45°.

[0016] like Figure 1 and Figure 2As shown, a filtration device for vinyl silicone oil includes a filter tank 1 with an open top, a discharge pipe 2 installed at the bottom of the filter tank 1, a tilting cylinder 3 hinged to the top of the filter tank 1, a sealing cap 4 hinged to the top of the tilting cylinder 3, a filter screen 7 and a hopper 5 installed sequentially from top to bottom inside the filter tank 1, an air blowing pipe 8 installed on the filter tank 1, the air blowing pipe 8 being located between the filter screen 7 and the hopper 5, the air blowing pipe 8 being connected to a compressed air source, a ball valve installed on the air blowing pipe 8, the air blowing pipe 8 being used to clean impurities on the filter screen 7, a sealing plug 6 screwed to the bottom end of the hopper 5, and a vibration support assembly installed inclined upward on the outer wall of the filter tank 1, the vibration support assembly being used to support and vibrate the tilting cylinder 3 in the open state.

[0017] like Figures 2 to 4 As shown, the vibration support assembly includes a support column 9 fixedly installed on the outer wall of the filter tank 1. A spring groove 10 is provided at the top of the support column 9. A compression spring 11 and a vibration plate 12 are installed sequentially from the bottom to the opening of the spring groove 10. The vibration plate 12 is L-shaped. The angle between the support column 9 and the vertical direction is 30°. A limiting rod 13 is connected to the vibration plate 12. A limiting groove 14 is provided on the support column 9. The limiting groove 14 is connected to the spring groove 10. The limiting rod 13 and the limiting groove 14 are slidably connected vertically. A vibration motor 15 is installed on the vibration plate.

[0018] During normal filtration operations, such as Figures 1 to 4 As shown, remove the sealing plug 6 and close the tilting cylinder 3 (even if the tilting cylinder 3 is coaxial with the filter tank 1). During filtration, impurities are left on the filter screen 7, and the silicone oil product passes through the filter screen 7 and is discharged and collected through the discharge pipe 2. When it is necessary to clean the filter screen 7, tilt the cylinder 3 outward and place it on the vibrating plate 12. Then, screw the sealing plug 6 at the discharge end of the hopper 5. Finally, open the ball valve on the air blowing pipe 8. Compressed air can thoroughly clean the impurities on the filter screen 7. For convenient and smooth discharge, the vibration motor 15 can be started to make the vibrating plate 12 vibrate elastically, thereby driving the tilting cylinder 3 to vibrate and accelerate the discharge of impurities.
