Cold-state asphalt ton box type transportation method

Abstract

The invention relates to a cold-state asphalt ton box type transportation method. The method comprises the following steps of 1, cooling hot-state asphalt, filling the asphalt ton box with the cooledhot-state asphalt, and cooling the ton box until the surface temperature is reduced to 46 DEG C or below; 2, loading the ton box into a transport vehicle and then transporting the ton box to a destination, wherein the transport vehicle is an ordinary truck; 3, unloading again to disassemble the ton box, and then heating the solid asphalt through the heating device to convert the solid asphalt intoliquid asphalt, wherein the heating device is movable; and 4, recycling and folding the empty box after the box is disassembled, and transporting the empty box back to a subpackaging site for later use. Compared with an automobile transportation tank car, the method has the price advantage, and the storage cost is reduced for customers; the ton box is small and exquisite in package, the box bodyis detachable, the destination heating efficiency is high, the occupied space is small after the box body is detached, recycling is convenient, and the operation turnover efficiency is higher than that of a railway container; and the return transport vehicle can load other cargos, no-load return is avoided, and cost is saved.

Description

technical field [0001] The invention belongs to the technical field of asphalt transportation, and in particular relates to a ton-box type transportation method of cold asphalt. Background technique [0002] Petroleum asphalt is a product of the crude oil processing process. It is a black or dark brown viscous liquid, semi-solid or solid at room temperature. The general petroleum asphalt is transported by tanker truck, asphalt bag mode and railway container mode. [0003] Railway containers are suitable for long-distance transportation, and the unloading site needs to be near the railway line, and the configuration requirements for unloading stations and heating stations are relatively high; the overall resources in the railway container market are about 9,000, and the operating cycle is long while the heating efficiency of the unloading site is low. Insufficient supply guarantee capacity. [0004] The bagging mode is the off-season of the asphalt market in winter, requirin...

AI Technical Summary

Problems solved by technology

[0007] 1. Asphalt tank trucks are suitable for medium and short-distance transportation. Long-distance transportation will cause asphalt to solidify and need to be heated when unloading, which will affect transportation efficiency;

[0008] 2. During the mid-transportation of asphalt tankers, with the loss of heat, the temperature of the asphalt decreases and the viscosity increases, which will result in a decrease in unloading efficiency and loss of tons;

[0009] 3. The asphalt tanker can only be transported one way, and it cannot be distributed when the empty vehicle returns, and the transportation cost is high;

[0010] 4. The transportation of asphalt tanker is a dangerous chemical vehicle, and the traffic control is strict

However, the current tank truck transportation mode is only suitable for short- and medium-distance routes, and the cost of long-distance logistics is high, and the insulation effect is insufficient, and heating is limited;

[0011] 5. Due to the lack of overall vehicle supply in the market, the price of automobile asphalt transportation has risen in peak seasons, and the overall guarantee is sufficient
