Description
Technical field
The present invention relates to a kind of producing device and method thereof of fiberglass sand-adding pipe, particularly relate to producing device and method thereof that a kind of wet type adds fw frp pipeline under the sand.
Background technology
The fiberglass sand-adding pipe is a kind of composite material tube, and it is to add to have certain thickness and can increase the quartz sand of GRP pipe intensity and fire resistance and the mixed layer of resin and making in the middle of the two-layer glass fiber layer that is entwined.At present, the simple glass steel conduit all utilizes dry type to add the sand method on last wrapping machine and makes, promptly earlier on the GRP pipe mould, make after the glass fiber inner liner, drystone English is sand flat the conduit upper that is layered on rotation by conveyer belt, with one deck strap sand is wrapped simultaneously, and spoon resin in the outside of cloth.In this process, because resin is to be penetrated in the quartz sand by itself flowability fully, thereby tends to occur resin and do not permeate or permeate uneven problem, thereby influence the quality of product; And since with this add that the sand method can only once reach 5～8mm add sand thickness, and if will reach design thickness just must repeatedly add sand and operate, thereby operating efficiency is lower; In addition, also there is serious dust raising phenomenon when adding sand, contaminated environment not only, and influence the healthy of operator; Especially the addition that adds resin in the sand process can't be measured, and tends to cause resin excessive, at this moment just needs the operative employee that unnecessary resin is wiped off, thereby cause serious waste.In addition since the diameter of GRP pipe is required increasing, have in addition require to reach more than the 4m, and common to go up wrapping machine be to add sand in conduit upper, so general factory building all can not meet the demands; In addition, operative employee's work high above the ground also can bring hidden danger to personal safety, and therefore this upward wrapping machine can't be finished the making of large glass steel conduit at all.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of accurate measurement, quartz sand and mixed with resin evenly, add that sand thickness is big, device height and low cost of manufacture, no dust pollution, handling safety and can satisfy the large glass steel conduit and make the producing device that the wet type that requires adds fw frp pipeline under the sand.
Another object of the present invention is to provide a kind of wet type to add the preparation method of fw frp pipeline under the sand.
In order to achieve the above object, wet type provided by the invention add fw frp pipeline under the sand producing device mainly by workbench, walking dolly, winding system, add sand system, mould and mould bracing frame and form; Described stationary table is on ground; Being provided with on the workbench can be by being positioned at the one side and driving the walking dolly that lower edge workbench length direction moves by motor-driven chain; Winding system then is fixed on the walking dolly with the partial devices that adds the sand system; And the mould that two ends are supported and can be rotated under the driving of motor by the mould bracing frame axially parallels with the length direction of workbench at a distance of certain distance setting and its with workbench.
Described winding system mainly is made up of creel, drag board, steeping vat, roll coater, filar guide, curing agent jar, flowmeter, resin storage tank, resin pump and blender; Creel and drag board are fixed on the ground of workbench away from mould one side, and steeping vat, roll coater and filar guide then are arranged on the walking dolly; The curing agent that is stored in the curing agent jar is transported to blender at compressed-air actuated effect lower edge pipeline after the flowmeter metering; Be stored in the resin that has added promoter in the resin container and and be transported to blender, and in this blender, mix for twining or adding sand and use with curing agent by the resin pump; Glass fiber by creel, drag board is through being offered steeping vat and comb and lead attached to placing in the steeping vat and enter filar guide behind the resin that has mixed on the roll coater that can rotate in steeping vat then with being soaked with by blender successively, introduces at last to twine towards the mould bottom tangential direction of workbench direction rotation and on the surface of mould and make inner liner or superficial layer.
The described sand system that adds mainly is made up of curing agent jar, flowmeter, resin storage tank, resin pump, blender, agitator, sand hopper, gauze axle and tensioning apparatus, chute and pressure roller; The agitator that is located at walking dolly top can be with from the quartz sand in its top sand hopper with above-mentionedly fully mix from the resin that has mixed in the blender; With the length direction of workbench perpendicular and be fixed on the walking dolly and the chute of agitator below in pass that one deck one end is wrapped on the GRP pipe mould and gauze belt that the other end is emitted from the gauze axle that is contained in the chute front end and the roll of gauze on the tensioning apparatus; Be arranged on chute terminal and with mould mutually roll-in pressure roller then can with by gauze belt together with extruding and damp sand bar through being located at the scraper plate strickling on chute two walls is squeezed on the inner liner that has twined outside the mould along the bottom tangential direction of mould from agitator it on.
But described chute front end also is provided with the positive left-hand thread leading screw that up-down adjustment is positioned at pressure between the pressure roller of chute end and GRP pipe mould.
Wet type provided by the invention adds the preparation method of fw frp pipeline under the sand and carries out according to the following order step:
(1) curing agent is even with the mixed with resin that adds promoter;
(2) glass fiber that will be soaked with resin after the above-mentioned mixing is wrapped in the surface of mould and makes inner liner from the tangential direction of GRP pipe mould bottom;
(3) resin and quartz sand after the above-mentioned mixing are mixed and make damp sand;
(4) damp sand is tiled on the gauze belt, and the gauze belt that will be loaded with the damp sand layer is wrapped on the inner liner that die surface made and makes from the tangential direction of GRP pipe mould bottom and adds layer of sand;
(5) will be soaked with the glass fiber that mixes the back resin at last and make superficial layer from the tangential direction of GRP pipe mould bottom adding on the layer of sand of being wrapped in that die surface made.
It is to twine and add sand in the tangential direction of GRP pipe bottom that wet type provided by the invention adds the producing device of fw frp pipeline under the sand and method thereof, so not only can make equipment reduce the height of a caliber, but also can save corresponding corollary equipment and investment; Because the present invention adopts wet type to add the sand method, thereby no dust pollution, and can not influence the healthy of operator; In addition, owing to reduced operative employee's working depth, thus eliminated hidden danger; Particularly pass through accurate metering before curing agent and the mixed with resin, can guarantee the accurate of addition like this; In addition, the thickness that adds sand can be regulated in the scope of 5～20mm, and therefore comparable prior art is increased work efficiency 2.5～4 times.
