DEVICE FOR MELTING AND HEATING PACKED BITUMEN Russian patent published in 2021 - IPC E01C19/08 C10C3/12 

FIELD: road construction.

SUBSTANCE: invention relates to the production of road construction materials, namely to the preparation of bitumen in the preparation of hot asphalt concrete mixtures. The device for melting and heating packed bitumen contains a case, a receiving chamber, registers of the bitumen melting and heating unit, a storage cavity, a temperature sensor and a drain device. The pipes of the first upper cutting row of the melting block register are made of round pipes or of pipes with a cross section in the form of an isosceles triangle and have a sharp knife blade in the upper part with a height of no more than 2 cm. Each pipe of the upper cutting row is laid on a round pipe of the second row of the melting block register. Each subsequent row of pipes of the melting block register, starting from the third, is displaced in parallel in the plane of the row relatively to the pipes of its upper row by no more than the radius of the round pipes.

EFFECT: technical result of the invention is an increase in the productivity of the device for melting and heating packed bitumen.
