Asphalt moulding method and system apparatus thereof

Abstract

The invention discloses an asphalt forming method, comprising the steps of pressurizing and cooling liquid asphalt and then jetting the asphalt via a nozzle-type former for cooling formation. The invention also provides a system device for implementing the method. The device is mainly composed of a forming pump (3), a gasification cooler (9), a cooling coil (10), a steam condenser (13), the nozzle-type former (16) and a link plate conveyor (17), the cooling coil (10) is disposed in the gasification cooler (9), the steam condenser (13) is connected with the gasification cooler (9), the nozzle-type former (16) is connected with the end of the cooling coil (10) and is disposed above the link plate conveyer (17). The device is simple in process and convenient in operation, and pressurizes andcools the asphalt in a sealed system for formation so that the asphalt has quite small contact area with the air, thus can solve the problems such as inferior appearance, high moisture and serious pollution, etc. The cured asphalt is columnar in shape, uniform in thickness and almost solid and has water content not more than 5%, which accords with the national standards.

Description

technical field [0001] The invention relates to an asphalt forming method, in particular to a solid-state forming method of liquid medium-temperature asphalt or modified asphalt produced in the process of coal tar processing. The invention also relates to a system device for carrying out the asphalt forming method. Background technique [0002] The formation of tar pitch (medium temperature pitch or modified pitch) in China basically adopts the technology of the former Soviet Union in the 1950s, that is, the pitch from the high-set tank directly enters the feeder (discharge funnel) with several mesh holes at the bottom without cooling. ), the asphalt flows out from the sieve hole and flows to the chain conveyor that is immersed in water and moves. Due to the large surface area of ​​the feeder and the high temperature of the asphalt, a large amount of asphalt fume volatilizes. Even if there is a fume hood, the fume still escapes due to the need to open the cover for inspecti...

AI Technical Summary

Problems solved by technology

Its mechanical transmission, power and other equipment are many, the operation and maintenance are complicated, the failure rate is high, the labor intensity is high, and the pollution is also large

In recent years, some coking manufacturers in China have introduced unique or patented technologies such as Coopers and French Irh, and adopted the nozzle forming method, which has a good forming effect, but there are also disadvantages such as uncontrollable forming temperature, large investment, and high technology transfer fees.

[0005] The purpose of the present invention is to provide an improved asphalt forming method, which is simple, can control the temperature, pressure and flow of asphalt, and can reduce the smoke and dust pollution in asphalt forming, and can solve the problem of traditional asphalt forming process at the same time. Asphalt agglomeration, hollow, brittle, high water content and other problems

[0006] Another object of the present invention is to provide a system device for implementing the forming method. The device has low investment and simple process, and effectively overcomes the disadvantages of the previous asphalt forming device that the temperature and pressure cannot be adjusted.
