Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

A high softening point asphalt granulation distributor is shown in figure 1-2, and comprises a heating extrusion cylinder 1, wherein the heating extrusion cylinder 1 is used for heating asphalt materials in the cylinder to enable the asphalt materials to be in a semi-molten state and extruded. The softening temperature of the asphalt is low, the asphalt can be softened at the temperature of 40-80 ℃, and the asphalt can have certain fluidity when the temperature reaches a semi-molten state of about 100 ℃. Granulation is achieved at this temperature, and much less heat energy is required to heat the bitumen, and the bitumen does not emit harmful gases.

Specifically, a heating pipe is arranged in the interlayer of the side wall of the heating extrusion cylinder 1, and the heating pipe raises the temperature in the heating extrusion cylinder 1 to 110 ℃ so that the asphalt material is in a semi-molten state. The top of the heating extrusion cylinder 1 is provided with a hydraulic cylinder for extruding the pitch in a semi-molten state out of the discharging sieve plate 2. A plurality of sieve pores which are distributed in an array are arranged on the discharging sieve plate 2. The sieve mesh is the cylinder hole of diameter 5mm, and a plurality of sieve meshes are the rectangular array and distribute. The discharge end of the discharge sieve plate 2 is connected with an insulating heat-resistant plate 4, and the insulating heat-resistant plate 4 is provided with sieve pores corresponding to a plurality of sieve pores of the discharge sieve plate 2. The insulating heat-resistant plate 4 is a polytetrafluoroethylene plate which has the characteristics of insulation and high temperature resistance, and also has good non-sticking property and is not easy to stick asphalt.

A granulating mechanism 3 is arranged below the discharging sieve plate 2, and the granulating mechanism 3 comprises a plurality of groups of electrothermal cutting wires 31 and an insulating frame 32. The insulating frame 32 is a square insulating frame and is used for tightening the plurality of groups of the electrothermal cutting wires 31. The two ends of the insulating frame 32 are respectively connected with an air cylinder 33, and the air cylinders 33 are guide pillar type air cylinders, so that extra slide rail guide is not needed. When the cylinder 33 extends, the insulating frame 32 is driven to reciprocate linearly.

The plurality of groups of electrothermal cutting wires 31 in the insulating frame 32 are longitudinally arranged and arranged in a single row; each group of the electrothermal cutting wires 31 corresponds to two rows of sieve holes of the discharging sieve plate 2. When the cylinder moves telescopically, each group of the electrothermal cutting wires 31 can cut strip asphalt materials in two rows of sieve holes into short column-shaped asphalt particles in one stroke. The multi-group electric heating cutting wires 31 can produce hundreds of asphalt particles in one second, and compared with the existing equipment, the efficiency is higher.

In order to prevent the suspended swing of the strip asphalt material extruded from the meshes of the insulating heat-resistant plate 4 and the inconvenience for cutting, the plurality of groups of electrothermal cutting wires 31 cling to the surface of the polytetrafluoroethylene plate to perform reciprocating linear motion, and the strip asphalt material is cut off and granulated uniformly. The melting point of the polytetrafluoroethylene is 327 ℃, the temperature of the electric heating cutting wire 31 is set to be 260 ℃ and higher than the melting temperature of the asphalt, so that strip asphalt materials with the diameter of 5mm can be cut into short column asphalt particles instantly.
