Extruder capable of conveniently and rapidly cooling plastic drainage plate

Abstract

The extruder comprises a heating cylinder, a pump chamber, a support and a water tank, the top of one side of the heating cylinder fixedly communicates with a feeding hopper, the middle of the heating cylinder penetrates through an equipment chamber, the equipment chamber is fixed to the top of a base, and a rotating cylinder is rotationally mounted in the heating cylinder; one end of the rotating cylinder penetrates through the heating cylinder and is rotationally connected with the base. According to the extruder capable of conveniently and rapidly cooling the plastic drainage plate, the pressing rollers, the spiral water-cooling pipe and the water tank are arranged, the two pressing rollers are matched to extrude materials to form the materials, meanwhile, the water chilling unit conveys cold water to the spiral water-cooling pipe through the liquid slip ring, the cold water primarily cools a finished product through the pressing rollers, then the finished product enters the water tank, and the water in the water tank secondarily cools the finished product; and meanwhile, deformation of the finished product in the period of time after the finished product is formed and before the finished product enters the water tank is avoided, the quality of the finished product is improved, and use is more practical.

Description

technical field [0001] The invention relates to the technical field of processing plastic drainage boards, in particular to an extruder for rapidly cooling plastic drainage boards. Background technique [0002] Plastic drainage board is an important building material. Its concave-convex hollow vertical rib structure can quickly and effectively guide rainwater, greatly reducing or even eliminating the hydrostatic pressure of the waterproof layer. Through this active water guiding principle, the effect of active waterproofing can be achieved. [0003] Existing extruders are usually not equipped with a drying structure, and water droplets adhere to the surface of the finished product after cooling, which is not only easy to pollute the surrounding environment, but also inconvenient for subsequent winding and storage, and the existing extruder Extruders usually only rely on the shear force of the screw to stir the materials in the heating barrel. This mixing method has limited e...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of extruder that is convenient for rapidly cooling the plastic drainage board, to solve the problem that the existing extruder proposed in the above background technology is usually not provided with a drying structure, and the surface of the finished product after cooling and forming is adhered to The water droplets are not only easy to pollute the surrounding environment, but also inconvenient for subsequent winding and storage, and the existing extruders usually only rely on the shear force of the screw to stir the materials in the heating cylinder, and the effect of this stirring method is limited. It is difficult to mix the materials in a large range, resulting in poor mixing uniformity of the finished product. The existing extruder usually only relies on the water in the water tank to cool the finished product, but before the material enters the water tank, it is affected by its own weight. Inevitably there will be slight deformation, leading to the problem of lower quality of finished products
