Abstract

This utility model discloses a liquid alkali addition device for PVB resin powder production, including a reaction tank top cover. A transmission cylinder is disposed at the top of the reaction tank top cover, and multiple transmission frames are disposed at the bottom of the reaction tank top cover. The multiple transmission frames are distributed in a ring with equal spacing about the transmission cylinder. A driven roller is disposed on one side of each transmission frame, and the driven roller is rotatably connected to the transmission frame via a first rotating shaft. A driving roller is disposed on the other side of the transmission frame, and the driving roller is rotatably connected to the transmission frame via a second rotating shaft.

Compared with the prior art, this application abandons the traditional fixed drip head and increases the number of drip heads from a single head to multiple heads. These multiple drip heads can reciprocate linearly along the transmission frames, thus expanding the range of alkali addition and improving the mixing efficiency of the alkali and raw materials, thereby increasing the processing efficiency of PVB resin.

Description

Technical Field

[0001] This utility model relates to the field of PVB resin production technology, and in particular to a liquid alkali addition device for PVB resin powder production. Background Technology

[0002] PVB resin is a thermoplastic polymer material produced by the condensation reaction of polyvinyl alcohol (PVA) and butyraldehyde. PVB resins come in various forms, among which PVB resin powder possesses excellent adhesion, film-forming properties, and flexibility, and is widely used in coatings, inks, ceramic decals, adhesives, 3D printing, and other fields. The preparation of PVB resin powder requires the continuous addition of alkali solution to adjust the pH value of the reaction solution. Existing alkali solution addition equipment typically has only one fixed drip head, resulting in a higher alkali concentration below the drip head than at other locations, leading to uneven alkali distribution. This hinders the adjustment of the reaction solution's pH value and reduces the PVB resin production efficiency. Utility Model Content
