Description

Technical Field

[0001] This utility model relates to the field of chloroprene rubber latex acidification technology, specifically to a chloroprene rubber latex acidification device. Background Technology

[0002] In the post-processing of chloroprene rubber, a freeze-coagulation method is used to freeze chloroprene latex into a film. To achieve this process, acetic acid needs to be added to the chloroprene latex to neutralize the stable pH of approximately 11 to approximately 5.2. At this state, the latex partially destabilizes, and after freezing, it completely loses its stability, which is beneficial for subsequent washing. However, due to the high viscosity of chloroprene latex, it is prone to gelation during flow, causing poor flow. Moreover, a small amount of gelation is always generated when chloroprene latex is neutralized with acetic acid. Therefore, there has been no satisfactory solution for acidification and automatic control of the material tray level.

[0003] In current production, extensive manual operation is used, which is labor-intensive, has low control precision, and makes it impossible to control the flow speed and position difference of the acidified latex during the circulation process.

[0004] Therefore, it is necessary to provide a new chloroprene latex acidification device to solve the above-mentioned technical problems. Utility Model Content

The bottom output end of the first rotary motor passes through the through hole into the interior of the mixing tank. A rotating shaft is fixedly connected to the bottom output end of the first rotary motor, and stirring rods are fixedly connected around the rotating shaft. The latex and acid can be mixed by the rotating shaft and stirring rods.

[0008] Preferably, the mixing tank has openings on both sides, and a transfer pipe is installed inside each of the two sets of openings. A valve is installed on the outside of each of the two sets of transfer pipes. The feed can be controlled by the transfer pipes and valves.

Compared with related technologies, the chloroprene rubber latex acidification device provided by this utility model has the following beneficial effects: This utility model provides a chloroprene rubber latex acidification device; This invention utilizes a mixing tank to acidify latex. When latex acidification is required, the control panel opens two sets of valves, allowing latex and acid to be fed through a transmission pipe. After the latex and acid enter the mixing tank in a certain proportion, the control panel controls the first rotary motor to rotate, which in turn rotates the shaft and multiple sets of stirring rollers to mix the latex and acid. The control panel also controls one output end of the second rotary motor to rotate, which in turn rotates the ball valve, allowing the acidified latex to flow through the connecting pipe into the flow channel, thus achieving the acidification and discharge of the latex. This invention can control the flow rate of latex by setting a comb-shaped baffle. After the acidified latex flows into the flow channel, the bottom output end of the push rod motor at the top of the adjustment frame can be extended and retracted by operating the control panel, which drives the comb-shaped baffle to move up and down. By adjusting the contact surface between the comb-shaped baffle and the flowing latex, the flow rate of the latex can be controlled. Attached Figure Description
