Method for producing screwed filter tube, special equipment and product

Abstract

The invention discloses a method for continuously producing a screwed filter tube, special equipment used by the method, and a product produced by using the method. The method comprises the following technological processes: a, carrying out raw materials preparation and carrying out extrusion molding by a plastic extruding machine; b, putting thermoplastics in a mold, molding screwed tube, and cooling; f, carry out traction by a tractor; g, coiling finished products, packaging and putting the finished products in a storage; and the method is characterized in that: c, punching by a punching machine; d, packaging by non-woven fabrics; e, continuous gluing by a gluer; and when performing the step (f), namely carrying out traction by the tractor, compacting the non-woven gluing opening simultaneously. The method solves the problems of the overlapping and looseness of non-woven fabric packaging existing in the production of the conventional screwed filter tube, and also solves the problems of continuous punching and continuous gluing on the screwed tube, which can save the non-woven raw materials, reduce the production cost, and greatly improve the production efficiency; and the produced screwed filter tube has the advantages of difficult blockage, smooth drainage and good using effect.

Description

Technical field: [0001] The invention relates to a plastic threaded filter pipe, in particular to a production method of the threaded filter pipe, special equipment used in the production method and products produced by the production method. Background technique: [0002] With the rapid development of the country's economic construction, the land for various infrastructure constructions is very tight. The construction of science and technology parks, development zones, etc., will encounter muddy land, swamps, rivers, rivers, and lakes. The traditional foundation treatment methods such as pumping water, removing silt, and excavating have a large amount of work, which greatly increases the cost of infrastructure construction. Cost. People have thought of many ways to reduce the amount of engineering and the cost of basic treatment. One of the more fashionable methods now is to use a new method of drainage with threaded filter pipes. This method is to bury the threaded filter ...

AI Technical Summary

Problems solved by technology

This production method and the threaded filter tube produced by this method have the following defects and deficiencies: 1, because the threaded filter tube produced by this method adopts non-woven fabric to be wound on the outer wall of the threaded filter tube in a spiral manner, that is, the latter A part of the non-woven fabric of the circle is pressed on the non-woven fabric of the previous circle, thereby increasing the consumption of non-woven fabric, causing waste of non-woven fabric, and also increasing the production cost of the threaded filter tube; 2. The cloth is only entangled and not consolidated. If the threaded filter tube is cut off, the non-woven fabric at the fracture is easy to loosen, which brings a lot of inconvenience to use and transportation; 3. During the use of the product, due to the former A joint gap is formed between the non-woven fabric of the first circle and the next circle of non-woven fabric, and a lot of sediment penetrates into the filter tube from the joint gap, and will block the drainage holes on the wall of the threaded filter tube, resulting in poor drainage and As for the effect of drainage
