Problems solved by technology

[0005] However, people cannot predict the location and degree of deformation in advance, so it is still possible that when a certain part of the bushing plate deforms, the cooling fins at this part cannot be adjusted, and the cooling length of the integral cooler is too long, which makes the bushing plate The deformed part has an uneven cooling effect on the bushing plate and the root, which leads to the problem of poor wire drawing effect

Embodiment 1

[0037] Embodiment 1, a method for adjusting a cooling device for a combined basalt fiber drawing bushing includes the following steps: preliminary adjustment: before production, adjust the height of the cooling fin 340 so that its upper side is flush with the lower end of the bushing 110, At the same time, set the width of the cooling fin 340 as Y, the center distance between the cooling fin 340 and the nozzle 110 near the side of the drawing bushing 1 as j, the vertical distance between the cluster origin A and the drawing bushing 1 as K, and the center of the drawing bushing The distance between the wire and the center of the outermost nozzle 110 is J, adjust j to satisfy j>YJ / K; set parameters: set the speed of the wire drawing machine, the speed of the oiler, The water volume of the sprayer is constant and consistent, and the wire drawing machine is set to change heads within a certain period of time h, and h satisfies h=5min; data collection: the area under each wire drawi...

Embodiment 2

[0038] Embodiment 2, a method for adjusting a cooling device for a combined basalt fiber drawing bushing, is characterized in that it includes the following steps: preliminary adjustment: before production, adjust the height of the cooling fin 340 so that its upper side is in line with the lower side of the bushing 110 The end faces are flush, and the width of the cooling fin 340 is Y, the center distance between the cooling fin 340 and the nozzle 110 close to the side of the wire drawing bushing 1 is j, the vertical distance between the cluster origin A and the drawing bushing 1 is K, and The distance between the center line of the wire drawing bushing and the center of the outermost nozzle 110 is J, adjust j to satisfy j>YJ / K; set parameters: set the speed of the wire drawing machine, the coating The rotation speed of the oiler and the water volume of the sprayer are constant and consistent. Set the wire drawing machine to change the head within a certain period of time h, an...

Abstract

The invention discloses a cooling device for a basalt fiber wire-drawing bushing. The cooling device comprises a mounting frame, wherein the mounting frame is arranged in correspondence to the wire-drawing bushing; at least two coolers are arranged on the mounting frame; and each cooler comprises a cooling frame, a plurality of cooling fins used for cooling the discharge spout of the wire-drawingbushing are arranged on one side of the cooling frame, and a water inlet pipe and a water outlet pipe are arranged at two ends of the other side of the cooling frame respectively. According to the invention, the plurality of coolers are arranged on the mounting frame, so the walking stroke of cooling water is short, local bias temperature is prevented from being generated during cooling, and the scrapping of the wire-drawing bushing due to blockage of the discharge spout caused by crystallization of basalt molten liquids at the discharge spout is avoided; the combined coolers can adjust the locally deformed part of the wire-drawing bushing, so the service life of the wire-drawing bushing is prolonged; and when one cooler is damaged, only the cooler needs to be replaced instead complete replacement of the coolers, so cost is reduced.

Description

technical field [0001] The invention relates to the technical field of basalt fiber production equipment, in particular to a cooling device for a basalt fiber drawing bushing. Background technique [0002] Basalt fiber is an engineering material with excellent properties in electrical, mechanical, chemical and optical aspects, and has become a raw material required in construction, transportation, electronics, electrical, chemical, metallurgy, national defense and other industries. The manufacture of basalt fibers usually requires high-temperature melting of batch materials into basalt molten liquid, and then drawing the basalt molten liquid. [0003] In the production process of basalt fiber, after the basalt melt is drawn into filaments by using drawing bushes made of platinum alloys, the glass filaments need to be cooled by drawing bushing coolers before subsequent processing. [0004] Chinese invention patent [CN200920162788.0] provides a wire drawing bushing cooler for...
