1. The utility model provides a novel polyester polyol case agitator, includes (mixing) shaft and a plurality of stirring leaf, and is a plurality of the one end of stirring leaf all with (mixing) shaft fixed connection, the (mixing) shaft with the stirring leaf is cylinder type cylinder body, the (mixing) shaft with all be provided with circular blind hole in the stirring leaf, just the blind hole of stirring leaf with the blind hole intercommunication of (mixing) shaft, set up the heater in the blind hole, the power cord of heater with the agitator motor of (mixing) shaft lower extreme is connected its characterized in that: and a heat-resistant sealant is arranged at the joint of the stirring shaft and the stirring shaft.

Technical Field

The invention relates to a stirrer, in particular to a novel stirrer for a polyester polyol box.

Background

The polyester polyol has high cohesive strength and adhesive force due to the fact that molecules of the polyester polyol contain more ester groups, amino groups and other polar groups, the polyester polyol has high strength and wear resistance, aliphatic (poly-adipic acid polyester) polyester diol is mainly used for producing casting polyurethane elastomers, thermoplastic polyurethane elastomers, microporous polyurethane soles, PU leather resins, polyurethane adhesives, polyurethane ink, color pastes, fabric coatings and the like, liquid polyester can be turbid when stored at low temperature, but the phenomenon can be eliminated by heating at about 80 ℃ for a short time without influencing the quality, so that the stored polyester polyol needs to be heated.

Disclosure of Invention

The invention aims to solve the problems and provide a novel polyester polyol tank stirrer.

The invention realizes the purpose through the following technical scheme:

the utility model provides a novel polyester polyol case agitator, includes (mixing) shaft and a plurality of stirring leaf, and is a plurality of the one end of stirring leaf all with (mixing) shaft fixed connection, the (mixing) shaft with the stirring leaf is cylinder type cylinder body, the (mixing) shaft with all be provided with circular blind hole in the stirring leaf, just the blind hole of stirring leaf with the blind hole intercommunication of (mixing) shaft, set up the heater in the blind hole, the power cord of heater with the agitator motor of (mixing) shaft lower extreme is connected.

Preferably, a heat-resistant sealant is arranged at the joint of the stirring shaft and the stirring shaft.

Specifically, the heater includes heating shaft and a plurality of heating leaf, heating shaft and a plurality of heating leaf set up respectively in blind hole in the (mixing) shaft and a plurality of blind hole in the stirring leaf.

Specifically, the heating blades have different rated temperatures and sequentially increase along the upper end to the lower end of the stirring shaft.

The invention has the beneficial effects that:

according to the novel stirrer for the polyester polyol box, the heater is directly arranged in the stirrer, so that the polyester polyol is heated more uniformly and more efficiently, energy can be saved by adopting step-type heating, meanwhile, the waste of the space of the storage box is reduced, and the storage volume is increased.

Drawings

FIG. 1 is a cross-sectional view of a novel polyester polyol tank stirrer according to the present invention;

Detailed Description

The invention will be further described with reference to the accompanying drawings in which:

as shown in figure 1, the novel polyester polyol box stirrer comprises a stirring shaft 1 and a plurality of stirring blades 2, wherein one end of each stirring blade 2 is fixedly connected with the stirring shaft 1, the stirring shaft 1 and the stirring blades 2 are cylindrical columns, circular blind holes 4 are respectively arranged in the stirring shaft 1 and the stirring blades 2, the blind hole 4 of the stirring blade 2 is communicated with the blind hole 4 of the stirring shaft 1, a heater is arranged in the blind hole 4, a power cord 7 of the heater is connected with a stirring motor 3 at the lower end of the stirring shaft 1, heat-resistant sealant is arranged at the joint of the stirring shaft 1 and the stirring shaft 1, the heater comprises a heating shaft 5 and a plurality of heating blades 6, the heating shaft 5 and the plurality of heating blades 6 are respectively arranged in the blind hole 4 in the stirring shaft 1 and the blind holes 4 in the plurality of stirring blades 2, the plurality of heating blades 6 have different rated temperatures and are sequentially increased along the stirring shaft 1 from the upper end to the lower end.

The novel polyester polyol box stirrer disclosed by the invention has the following working principle:

when the polyester polyol in the storage box needs to be heated, the stirrer is turned on, meanwhile, the heater in the stirrer works to generate heat, meanwhile, the density of hot water is smaller than that of cold water, so that the temperature of the polyester polyol at the upper part in the storage box is higher than that of the polyester polyol at the lower part, and the temperature at the upper end of the stirrer is lower than that at the lower end of the stirrer, so that the polyester polyol in the storage box can be heated more uniformly by the stirrer, and energy is saved.

The technical solution of the present invention is not limited to the limitations of the above specific embodiments, and all technical modifications made according to the technical solution of the present invention fall within the protection scope of the present invention.
