Example (b): as shown in attached figures 1-6, the high-strength FDY polyester filament comprises a polyester melt material which comprises a strength filler, wherein the strength filler is any one or a mixture of glass powder or silicon micropowder.
In the embodiment, the glass powder or the silicon powder is a common hardness filler, and after a proper amount of the glass powder or the silicon powder is added, the strength of the FDY polyester filament yarn can reach 5.0-6.0 CN/dtex. If the strength filler is changed to silicon carbide or the like with higher hardness, the final filament strength should be improved, but the overall economic benefit is not as good as the present invention.
In the drawing spinning process of the FDY polyester filament: the spinning temperature is 260-280 ℃, the stretching ratio is 1.6-2.0 times, the heat setting temperature is 120-130 ℃, and the winding tension is 2.0-2.3 cN.
In this embodiment, the draw ratio and the winding tension are slightly increased compared with those of the conventional FDY polyester filament yarn production process, which is also a value that can be achieved only after the addition of the hard filler, and the final reaction is reflected in the filament performance, i.e., the filament has relatively high strength.
The particle sizes of the glass powder and the silicon micro powder are 5.0-70.0nm, and the glass powder and the silicon micro powder are prepared by grinding with a middle water-cooled ball mill.
In this embodiment, if the particle size of the glass frit and the silica powder is smaller than the above range, the workload of the preliminary grinding operation is significantly increased, and if the particle size is larger than the above range, the hardness filler in the filament is significantly raised, which affects the hand feeling in use, and thus the above relatively suitable particle size range is determined.
The utility model provides a middle part water-cooled ball mill, includes shell 11, sets up lower inlet pipe 12 and last discharging pipe 13 on the 11 lateral walls of shell, rotation axis 14, stirring post 15, and set up abrasive material on the 11 roof of shell adds hole 16, still including cup jointing the setting and being in the cavity block ring unit 1 of 14 lower parts of rotation axis department sets up in the inlet pipe 12 down and connect the cavity of cavity block ring unit 1 is intake ring unit 2, sets up on the cavity block ring unit 1 upper surface and be used for the cooling the water-cooled tube 3 of the 11 lateral walls of shell sets up 3 upper end mouth of pipe department of water-cooled tube and with the cavity intercommunication ring unit 4 that rotation axis 14 cup jointed, and set up in the abrasive material adds in the hole 16 and with cavity play water ring unit 5 that cavity intercommunication ring unit 4 is connected.

First, cavity ring unit 2 that intakes, cavity ring unit 5 self shape are the ring shape, can wait to grind the material and add, grinding ball a adds the operation in the middle of the ring, therefore whole water-cooling structure does not influence normal grinding operation.
Secondly, the grinding balls a are glass powder and silicon powder with the particle sizes meeting the requirements of the range, so that materials to be ground with overlarge particle sizes, which are added at the lower feeding pipe 12, can be discharged at the upper discharging pipe 13 in a reasonable particle size state.
Thirdly, the hollow water inlet ring unit 2 and the hollow water outlet ring unit 5 are installation and fixation parts of the whole water cooling structure, the former ensures that the water cooling structure is not easy to loosen up and down, and the latter ensures that the water cooling structure is not easy to loosen left and right.
Fourthly, the number of the water-cooling tubes 3 is 4-10, and the water-cooling tubes are positioned at a crack between the rotating area of the stirring column 15 and the inner side surface of the shell 11, so that the side wall of the shell 11 and the grinding balls a can both obtain relatively quick and comprehensive water-cooling effect.
And finally, the advancing sequence of the cooling water is sequentially a hollow water inlet ring unit 2, a hollow clamping ring unit 1, a water cooling pipe 3, a hollow communicating ring unit 4 and a hollow water outlet ring unit 5, so that the middle inside the whole grinding machine is ensured, and the efficient water cooling operation of sealing, omnibearing and direct contact can be carried out.
The hollow snap-fit ring unit 1 comprises a lower hollow ring 101 with an inner ring surface snap-fit with the rotating shaft 14, and a transverse connecting pipe 102 arranged on the annular side wall of the lower hollow ring 101 and used for connecting the hollow water inlet ring unit 2.
In this embodiment, the inner diameter of the lower hollow ring 101 is 3-8cm larger than the diameter of the rotating shaft 14, and the rotating shaft 14, which originally has no limit at the lower end and is freely swayed back and forth, is clamped and limited, so that the whole rotating and stirring action is more stable and ordered.
Wherein, the grinding operation mainly depends on the grinding balls a, the inner side surface of the shell 11 and the self material hardness of the stirring column 15, and the rotation action of the stirring column 15 is minor, so the rotation speed of the stirring column 15 is relatively slow, which is a prerequisite condition that the whole water cooling structure can be installed in the shell 11.
The hollow water inlet ring unit 2 comprises a side hollow circular ring 201 and a water inlet pipe 202, wherein the outer annular surface of the side hollow circular ring is clamped in the lower feed pipe 12, is connected with the transverse connecting pipe 102, and is used for vertically fixing the hollow clamping ring unit 1, and the water inlet pipe is arranged on the side hollow circular ring 201 and is used for being connected with a water pump.
In this embodiment, the outer annular surface of the side hollow circular ring 201 is tightly attached to the inner annular surface of the lower feeding pipe 12, so that the whole water cooling structure can be stably installed.

In this embodiment, since the upper end of the rotating shaft 14 is fixed by the shaft body mounting hole, the upper end does not need to be limited, and therefore, the inner diameter of the upper hollow ring 401 can be made relatively larger.
In addition, the height of the upper hollow ring 401 must be higher than the uppermost stirring column 15, so as to prevent the stirring column 15 from hitting the vertical connecting pipe 402.
The vertical connecting pipe 402 is inserted upward into the abrasive adding hole 16, and the inner ring of the upper surface of the upper hollow circular ring 401 is inclined downward.
In this embodiment, the abrasive adding hole 16 is located above the upper hollow ring 401, so that the inclined upper surface of the upper hollow ring 401 can ensure that the grinding balls a are not easily accumulated on the upper hollow ring 401 accidentally.
In addition, the height of the upper surface of the whole ground material is lower than that of the upper hollow circular ring 401 and is positioned at the height position of the upper discharge pipe 13, so that the ground material can be smoothly discharged.
The hollow water outlet ring unit 5 includes an upper hollow ring 501 disposed on the vertical connecting pipe 402 and having an outer circumferential surface engaged with the abrasive adding hole 16, and a water outlet pipe 502 disposed on a top plate of the upper hollow ring 501 and connected to a water tank.
In this embodiment, the outer annular surface of the upper hollow circular ring 501 also needs to be tightly attached to the annular surface of the circular abrasive adding hole 16, so as to ensure that the whole water cooling structure is not prone to left-right shaking.
And silicon carbide coatings are arranged on the outer side surfaces of the hollow clamping ring unit 1, the hollow water inlet ring unit 2, the water cooling pipe 3, the hollow communicating ring unit 4 and the hollow water outlet ring unit 5.
In this embodiment, the glass powder and the silicon powder have relatively high hardness, so that the outer side surface of the whole water-cooling structure, the inner side surface of the shell 11, and the surfaces of the rotating shaft 14 and the stirring column 15 can be coated with the silicon carbide coating, so as to ensure that the equipment is not easily abraded.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. These are non-inventive modifications, which are intended to be protected by patent laws within the scope of the claims appended hereto.
