Embodiment Construction

[0018] Referring to Fig. 1 , a resin quartz sand grading premixing equipment of the present invention includes a sand conveying device; a premixing agitator 4 arranged downstream of the outlet end of the sand conveying device. The premix agitator 4 has a quartz sand inlet and at least one binder and auxiliary material injection port 5 and a stirring part arranged in the premix equipment, wherein the binder can be such as resin; the premix The mixing agitator 4 continuously conveys the quartz sand material during the stirring process; the adhesive and auxiliary material injection port 5 is arranged downstream of the quartz sand inlet; the premixing agitator 4 is provided with a mixing material outlet export port. The sand conveying device is a metering feed conveyor 7 . The metering supply conveyor 7 has a sand conveying shell, and a spiral part is arranged in the cylindrical shell, and the sand conveying shell and the spiral part form a sand conveying screw conveyor (commonly...

Abstract

A kind of facilities of preliminary mixing for manufacturing the glass fiber reinforced thermal-setting resin sand-inclusion piping. Including: the sand box, the transporting device, its characteristic lies in: a measure feed transporting machinery is linked to the outlet of the sand box, at the exit of the transporting machinery is linked with a premixing device, a rolling device is linked to the outlet of the preliminary mixture, the said rolling device includes the two parallel rolls, two parallel cloth sand-hood. After the pressing device, it establishes the belt conveyer which matches with a rotating mold. The beneficial result of the invention is that it lowers the resin content effectively, economizes direct material cost of the product. It is advantageous to control the product quantity, the resin is soaking well, the mezzanine sand layer density is high, raising the quantity of the product effectively.

Description

technical field [0001] The invention relates to a gradation premixing equipment for resin quartz sand. Specifically, it is used to produce sand feeding equipment in fiber winding reinforced thermosetting resin sand-filled pipelines. Background technique [0002] The known feeding equipment for adding sand to glass fiber reinforced thermosetting resin sand pipes is as follows: the quartz sand with a mesh number of 20 to 40 mesh accounts for more than 80%, the maximum particle size shall not exceed 10 mesh, and the weight percentage is less than or equal to 7% after grading , rolled to the outer surface of the rotating mold through a conveyor belt or a pocket of abrasive cloth, and then manually or semi-manually impregnated with resin on the outside of the quartz sand layer. The related prior art is the method disclosed in Chinese patent document CN2579572Y. This sand adding process has a low degree of automation, the resin in the sand layer is not easy to penetrate, the resi...
