Abstract

The invention provides a urethane resin stirring and synthesizing device which is mainly used in the synthesis industry of raw materials of high-viscosity polyurethane (PU). The invention designs the urethane resin stirring and synthesizing device especially for solving the problem that a common stirring device can hardly stir evenly since the viscosity of size in the prior polyester size kettle is overhigh. In the invention, a polyurethane (PU) size kettle is provided with a bottom blade, a middle guide plate, a wall scrapping blade, and a detachable blade-type baffle; under the mutual matching of the bottom blade, the middle guide plate, the wall scrapping blade, and the detachable blade-type baffle, high-viscosity polyurethane size can not adhere to the bottom wall of the kettle and a stirring shaft during stirring and synthesizing.

Description

Urethane resin stirring and synthesizing device

Affiliated technical field:

The present invention relates to a kind of urethane resin stirring and synthesizing device, be mainly used in the compound probability of high viscosity urethane (PU) raw material.

Background technology:

Urethane (PU) slurry still is widely used in PET industry, too high because of slurry viscosity, original equipment adopts general whipping appts design, and form is relatively backward, in use often stir inhomogeneous, because of viscosity index is too high, can reach several ten thousand centipoises, slurry is easy to be bonded on the still diapire or is bonded on the stir shaft during stirring, cause chemical reaction incomplete, reaction mass undercompounding, such slurry still reaction efficiency is low, and yield rate is not high.

Summary of the invention:

Too high for solving present polyester slurry still because of slurry viscosity, the problem that general mixer can't stir, ad hoc meter urethane resin stirring and synthesizing device, its main technical schemes is such:

At first be located at urethane (PU) slurry still stir shaft lower end and set a grade stirring blade, paddle is designed to corresponding shape at the bottom of the still, and the operation of applying still diapire has solved the problem of pasting in the material reaction at the bottom of the still.

Then, diversion belt in the middle of establishing above the lower gear paddle, diversion belt make because of the lower gear paddle stirs the bottom material that turns over liter and further stir up and down around stir shaft skew surface design in the shape of a spiral, and motion centrifugal force has solved the problem that material is pasted stir shaft simultaneously.

Secondly, establish on stir shaft and scrape the wall paddle, scrape the wall paddle and be " T " font, the still wall is close in " T " word upper end, and the lower end links stir shaft, and the upper end end face is referred and synthesized mutually with the leaf formula of tearing open baffle plate hereinafter described.

Once more, stir up and down at diversion belt under the situation of high-viscosity material, for solving the problem of material adhesion still wall, be provided with again and tear leaf formula plate washer open, tear leaf formula plate washer open and be arranged at the still wall, parallel with the still wall, and keep a segment distance, be " T " font structure, " T " font lower end links to each other with the still wall, tears leaf formula plate washer open and scrapes the wall paddle and combine, with their relative movement, play shearing action, prevented that simultaneously high-viscosity material is adhered to the still wall logistics, when blocking the rotation of material when stirring because of the material of centrifugal force to still wall high-speed motion.

By the lower gear paddle, middle flow deflector is scraped the wall paddle, tears the effect of cooperatively interacting of leaf formula baffle plate open, and the high viscosity polyurethane slurry still diapire no longer occurs being adhered to, the phenomenon of stir shaft in stirring the synthetic process.

The present invention can play and the high viscosity polyurethane slurry be reached stir the action effect that reacts completely.

Description of drawings: accompanying drawing 1 is principle of the invention figure, wherein:

(1) polyurethane slurry kettle, (2) lower gear paddle, the wall paddle scraped in (3) " T " font,

(4) tear leaf formula plate washer open, diversion belt in the middle of (5), (6) stir shaft;

Embodiment:

Narrate concrete working process below in conjunction with accompanying drawing:

Lower gear paddle (2) is installed on stir shaft (6) end, match with polyurethane slurry kettle (1) bottom shape, material is stirred turn over liter, solved the problem at the bottom of material is pasted still, middle diversion belt (5) is the skew surface design around stir shaft (6), making the bottom turn over the bottom material that rises because of lower gear paddle (2) stirs further stirs up and down, on stir shaft (6), establish " T " font and scrape wall paddle (3), " T " font is scraped wall paddle (3) upper end and is close to the still wall, the lower end links stir shaft, the upper end end face with tear leaf formula baffle plate (4) open and refer and synthesize mutually, under the situation that high-viscosity material stirs up and down,, be provided with again and tear leaf formula plate washer (4) open for solving the problem of material adhesion still wall, tear leaf formula plate washer (4) open and be " T " font structure, be arranged on the still wall of polyurethane slurry kettle (1), end face is parallel with the still wall, and keeps a segment distance, scrape wall paddle (3) with " T " font and refer and synthesize mutually, and do relative movement in use.
