Heat-free temperature-controlled blending silo

Abstract

The invention discloses a heating-free temperature-controlled blending silo, which comprises a main transmission shaft, wherein the main transmission shaft is provided with a spiral blade on a part ofa feeding bin, a stirring blade is arranged on a part of the main transmission shaft on the blending silo, the high speed rotation of the main transmission shaft drives the spiral blade and the stirring blade to rotate at a high speed, the materials are mutually rubbed inside the blending silo, and the material and the inner bin of the blending silo are subjected to heat generation for material blending, the sealing effect of the feeding bin and the blending silo is good, the heat is not easy to be lost, the unit energy consumption is low, the mixing time is short, and the pushing effect of the spiral blade makes the material not easy to be blocked during a conveying process, and in addition, the material can be dried during a mixing process, which reduces the production cost; a dissection blending silo body is employed, which is convenient for maintenance. at the same time, the blending silo uses the cooling water circuit for temperature control, avoids the decomposition of the material due to excessive temperaturee, and does not affect the performance of the fiber reinforced composite material.

Description

technical field [0001] The invention relates to a mixing bin, in particular to a heating-free temperature-controlled mixing bin, which belongs to the field of mechanical technology. Background technique [0002] Fiber Reinforced Polymer (or Fiber Reinforced Plastic, referred to as FRP) is formed by reinforcing fiber materials, such as glass fiber, carbon fiber, aramid fiber, etc., and matrix materials through winding, molding or pultrusion. composite material. According to different reinforcing materials, common fiber reinforced composites are divided into glass fiber reinforced composites (GFRP), carbon fiber reinforced composites (CFRP) and aramid fiber reinforced composites (AFRP). [0003] The production process of fiber-reinforced composite materials needs to use a blender. The blender generally includes a feeding bin and a mixing bin.

Problems solved by technology

[0003] The production process of fiber-reinforced composite materials needs to use a blender. The blender generally includes a feeding bin and a mixing bin. The feeding bin is used for the entry of fibers and matrix materials, and the mixing bin is used for mixing fibers and matrix materials; The currently used blending machines generally use electric heating or oil heating to mix the fiber and the matrix material. The unit energy consumption is high and the mixing time is long. During the feeding process of the fiber and the matrix material, it is very easy to cause blockage. At the same time, the fiber and The water vapor and other volatile gases produced by the matrix material during the mixing process are not easy to discharge. In addition, the bin body of the mixing bin is an integral structure, and the closed bin structure is inconvenient for maintenance. Because the material generates a large amount of gas during the mixing process Heat, when the temperature is too high, the material is easy to decompose, which reduces the performance of the fiber reinforced composite material
