Abstract

The invention relates to the building materials industry, namely to devices for the preparation of bitumen. The purpose of the invention is to increase productivity and reduce the cost of bitumen preparation. The installation for the preparation of bitumen contains a heat-insulated body 1, in the upper part of which the melting unit 5 is located in the form of fixed heaters made in the shape of container 6. In the lower part of the body there is a melting unit 4. The container 6 is supported on the melting unit 5 and is made with an internal volume exceeding the volume of the latter for free introduction during the smelting of bitumen. The process of deinking and melting bitumen occurs simultaneously. 4 il.

Description

The invention relates to the building materials industry, namely to devices for the preparation of bitumen.

The purpose of the invention is to increase productivity and reduce the cost of bitumen preparation.

Fig. 1 shows an installation for preparing bitumen, a general view, in Fig. 2, view A in Fig. 1. Fig. 3 shows view B in Fig. 1; figure 4 - section bb In fig.Z.

The installation for preparing bitumen contains a heat-insulated body 1 and a loading hatch 2 with a lid 3. In the lower part of the body 1, the melting unit 4 is located, in the upper part - the melting unit 5 in the form of fixed heaters arranged in the shape of the container 6. the grille 7, which has the first 8, the second 9, and the lower 10 Russ, the edges 11 of which are offset from each other, for example, by half the lattice spacing. The ribs of each tusa are pointed. The grille is made of tubes through which coolant passes, for example steam, for which an inlet 12 and a vapor outlet 13 are provided. For a more accurate installation of the container 6, guides 14 are made on the inner surface of the housing.

A pump 15 is installed to pump out the molten bitumen. The container is supported on the smelting unit 5 and is made with an internal volume exceeding the volume of the latter, for free introduction during the smelting of bitumen.

The installation works as follows.

Open the cover 3 of the loading door 2 d install the container 6, for example, in the form of glasses in an overturned position on the block 5 melting. Block 5 for melting, melting bitumen, cuts the edge of the upper base into solid bitumen, cutting a piece in the shape of a cylinder from it. The incision of the melting unit 5 into bitumen is facilitated by the lowering of the container 6 under the force of gravity. The container 6 outside is heated by heat from the already melted and heated to 1300

150 ° C of bitumen, a molten layer of bitumen is formed along the contour of the container 6. The longitudinal edges of the smelting unit 5 are cut - the wall layer of solid bitumen is melted, which is lowered into the first grade 8 of the lattice 7.

I

When the melting unit 5 completely enters the inside of the container 6, it closely contacts with its inner walls, contributing to their better purification from bitumen residues. The ribs 11 of the races of the hot lattice are cut — pieces of bitumen are melted into smaller ones. Moreover, the cutting is carried out both along and across the pieces, thus exposing a large number of faces of solid bitumen, with the result that it melts faster. From Russias 8 and 9, already small pieces of bitumen fall onto the lower Russian 10, whose fins 11 are displaced, for example, by 0.5 steps relative to the edges of the previous Russ4, and are additionally crushed, almost completely melted. The bitumen flows from English 10 into the lower part of housing 1, where the heat from the heaters of the melting unit 4 is heated to 130-150 ° C. The bitumen melted and heated to the required temperature is pumped out of the housing 1 by means of a pump 15.
