TH76282B - A device for cutting asphalt lines into lumps. Or any other similar shape, the device consists of a pilot system, a flow of asphalt line - Google Patents

Abstract

The proposed invention involved a device for cutting asphalt lines (20) into blocks of asphalt (80) or similar shapes. The device is immersed in a bath of cooling fluid (30). It consists of a rotating cutterhead (60 and 70) consisting of a rotating cylinder. That are equipped with multiple cutting blades And the cutting head rotates counter to the cylinder Rotating cutter head and counter rotating cutter The cylinders are aligned facing each other to cut the asphalt (20) that passes between the The two cutting heads into asphalt blocks (80) are characterized by that they consist of one device (40) for piloting the flow of the asphalt line to the cutting device (60 and 70). Attach to the aforementioned cutting equipment (60 and 70). To make the asphalt line (20) flow vertically down between the cylindrical cutter and the conical cutter.

Claims (9)

1. A device for cutting asphalt strips (20) into asphalt aggregates (80) or similar shapes. The device is immersed in a cooling fluid bath (30). Said device comprises a rotating cutting head assembly (60 and 70) consisting of a cylindrical rotating cutting head fitted with several cutting blades and a cylindrical counter-rotating cutting head. Said rotating cutting head and cylindrical counter-rotating cutting head are arranged facing each other to cut the asphalt strips (20) passing between them into asphalt aggregates (80). The device comprises a device (40) for guiding the flow of the asphalt strips to the cutting devices (60 and 70). Said guide device (40) is fitted to the cutting devices (60 and 70) to cause the asphalt strips (20) to flow vertically down between the cylindrical cutting heads and the counter-rotating cylindrical cutting heads. 2. An apparatus for cutting asphalt strips (20) into asphalt blocks (80) or similar shapes as claimed in claim 1, wherein the apparatus also comprises a second asphalt strip guide device (90) mounted below the cutting devices (60 and 70) to act as a guide for the asphalt strips (20) coming out of the cutting devices (60 and 70) that have been cut into blocks (80) to flow into the cooling fluid reservoir (30). 3. A device for cutting asphalt strips (20) into asphalt blocks (80) or similar shapes as claimed in claims 1 or 2, such that the first and/or second asphalt strip guide devices (40 and 90) comprise at least one set of two baffles (401, 421, 901). The baffles (401, 421, 901) are arranged facing each other to form a leading space, a narrow guideway (400, 420, 900) facing the cutting devices (60 and 70). 4. A device for cutting asphalt strips (20) into asphalt blocks (80) or similar shapes claimed in claim 3, wherein the baffles (421) are hydrodynamically shaped in order to improve the circulation of coolant around the first and/or second asphalt strip guide devices (40 and 90) when the devices are immersed in a coolant bath (30). 5. A device for cutting asphalt strips (20) into asphalt blocks (80) or similar shapes as claimed in claim 4, wherein the baffle (421) has a hydrodynamic shape in the form of a longitudinally cut tube so as to cause a circulation of coolant into the baffle (421) when the device is immersed in a coolant bath (30). 6. A device for cutting asphalt strips (20) into asphalt blocks (80) or similar shapes claimed in any one of claims 3 to 5, wherein the baffles (401 and 421) of the first asphalt strip guide device (40) are arranged in the shape of a feeding cone (411). 7. A device for cutting asphalt strips (20) into asphalt blocks (80) or similar shapes as claimed in any one of claims 3 to 6, wherein the baffles (401, 421 and 901) are provided with at least one opening (431, 432, 433) to provide a passage for coolant to flow through when the device is immersed in a coolant bath (30). 8. A device for cutting asphalt strips (20) into asphalt blocks (80) or similar shapes as claimed in any one of claims 1 to 7, such that the device further comprises a cutting cover 50 that protects the cutting devices (60 and 70). The cutting cover 50 is arranged to cover the cutting devices (60 and 70) in such a way that it provides a circulation of cooling fluid around the cutting devices (60 and 70) by means of the rotation of the cutting devices (60 and 70). 9. A device for cutting asphalt strips (20) into asphalt blocks (80) or similar shapes claimed in claim 8, such that there are gaps (450, 950) between the cutting strip cover assembly 50 and the first and/or second asphalt strip guide devices (40 and 90). 1. A device for cutting asphalt strips (20) into asphalt blocks (80) or similar shapes claimed in claim 8, such that, with respect to the cutting strip cover assembly, the first and/or second asphalt strip guide devices (40 and 90) are formed into a single part with the cutting strip cover assembly 50.
