Description

Technical Field

[0001] The utility model relates to the technical field of methyl ethyl ketone peroxide production, in particular to a neutralization reaction device for methyl ethyl ketone peroxide production. Background Art

[0002] At present, butanone peroxide is an organic compound, mainly used as a room temperature curing agent for unsaturated polyester resins, an initiator for organic synthesis, a bleaching agent,

[0003] Among them, methyl ethyl ketone peroxide is the most widely used initiator for unsaturated polyester resin in the world. More than 90% of the initiators used in injection molding are methyl ethyl ketone peroxide, which has low price, good performance, extremely convenient use, and easy mixing with resin. Methyl ethyl ketone peroxide needs to be neutralized during the production process. The current neutralization reaction equipment has poor neutralization effect and poor reaction rate.

[0004] However, butanone peroxide is a colorless, transparent, viscous liquid. When adding materials, it is very easy to adhere to the inner wall, which is not only difficult to clean, but also very likely to cause inaccurate adding. Therefore, it is necessary to design a new technical solution to solve this problem. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a neutralization reaction device for producing methyl ethyl ketone peroxide, comprising a neutralization tank, a discharge pipe is connected and installed in the middle of the bottom side of the neutralization tank, a feed cylinder is connected and installed in the top of the side wall of the neutralization tank, and a quantitative feed extrusion mechanism is installed in the feed cylinder;

[0007] The quantitative feeding extrusion mechanism includes a piston hole opened in the middle of one side of the feed barrel, a piston rod movably installed in the piston hole, an extrusion plate fixedly installed on the other side of the piston rod, a discharge pipe connected and installed in the middle of the other side of the feed barrel, and a material guide pipe connected and installed at the top of the feed barrel. The extrusion plate is movably installed on the inner wall of the feed barrel, and the other end of the discharge pipe is connected and installed in communication with the inside of the neutralization tank.

[0008] As an optional solution of the technical solution of the present application, a servo motor is fixedly installed in the middle of the top of the neutralization tank, the drive output end of the servo motor is connected to the transmission shaft, and a rotating rod is fixedly installed at the other end of the transmission shaft, which can drive the rotating rod and the stirring rod to rotate.

[0009] As an optional solution of the technical solution of the present application, a stirring rod is fixedly installed at the bottom of the rotating rod, and a scraper is fixedly installed on the top of the rotating rod. The side wall of the scraper fits with the inner wall of the neutralization tank, so that the materials inside the neutralization tank and the inner wall can be mixed.

[0010] As an optional solution of the technical solution of the present application, solenoid valves are fixedly installed on the discharge pipe, the guide pipe and the discharge pipe to control the internal flow of the discharge pipe, the guide pipe and the discharge pipe.

[0011] As an optional solution of the technical solution of the present application, scale lines are engraved on the outer wall of the feed barrel, and an observation mirror is fixedly installed in the middle of the neutralization tank to detect the internal state of the neutralization tank.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The technical solution of the present application opens the solenoid valve of the material guide pipe and closes the solenoid valves on the discharge pipe and the discharge pipe, so that the operator holds one side of the piston rod and pulls the extrusion plate on one side of the piston rod to move outward, so that the methyl ethyl ketone oxide inside the material guide pipe is continuously drawn into the feed barrel, and the capacity of methyl ethyl ketone oxide is added as needed. The operator can stop pulling the piston rod, open the discharge pipe, close the solenoid valve of the material guide pipe, and push the extrusion plate at one end of the piston rod in the opposite direction to introduce a certain amount of methyl ethyl ketone oxide in the feed barrel into the neutralization tank, which not only ensures the quantitative addition of methyl ethyl ketone oxide, but also prevents the methyl ethyl ketone oxide from adhering to the inner wall of the feed barrel through extrusion by the extrusion plate.

[0014] 2. The technical solution of the present application is that a stirring rod is fixedly installed at the bottom of the rotating rod, and a scraper is fixedly installed at the top of the rotating rod. When the quantitative feeding extrusion mechanism is pushed to introduce methyl ethyl ketone peroxide into the neutralization tank, the servo motor on the top of the neutralization tank is driven to synchronously drive the stirring plate and the scraper on the rotating rod to rotate, so that the materials inside and on the inner wall of the neutralization tank can be stirred, which greatly improves the neutralization reaction efficiency for the production of methyl ethyl ketone peroxide inside the neutralization tank.
