SU268926A1 - METHOD OF TRANSPORTATION OF SUGAR-RAWS TO THE SUDAH - Google Patents

Description

Known methods of transporting saharasyrts on ships in bulk involve the use of dry cargo vessels or special sugar-transport vessels. In the practice of world shipping with a steady flow of cargo, empty ship runs are not compromised. The same thing happens with oil tankers.

According to the proposed method, to reduce the cost of transportation by disposing of free runs of oil tankers for transporting raw sugar, tankers are loaded with raw sugar after unloading from oil products or other liquid cargo, cleaning and processing with detergents so that the temperature raw sugar did not exceed ambient air temperature by more than 12 ° С, and the humidity of the saharase was not more than 0.7%, and during its transportation in cargo tanks it is maintained the equilibrium moisture regime of the tank insulation, sealing and periodical ventilation.

Insulation tanks can be different. In the present embodiment, raw sugar is loaded into medium tanks, and nasal, fodder and airborne tanks are used as the insulating layer. In addition, in order to increase the insulation strength and facilitate unloading of cargo tanks on their bottom, removable elastic flooring is laid before loading with raw sugar. For a more complete loading of tanks and their effective unloading, a pipe is suspended vertically under the deck of each cargo tank, which is closed with a lid when loading, and when unloading the suction valve of the air handler is opened and passed into the pipe. In the process of loading and unloading, the tube is periodically vibrated in a vibrator with a vibrator.

FIG. 1 shows the loading scheme of a tanker, for example, when filling seven medium tanks, indicated by Roman numerals and letter indices; in fig. 2 - cross-section of the tanker during loading; in fig. 3 - the same, prp unloading. After unloading from the tanks of petroleum products

all pipelines, bulkheads and kit are cleaned in a chemical-mechanized way using a detergent preparation. The car wash serves at the same time as tank degassing. After washing the bottom of medium (cargo) tanks

stack removable elastic flooring / tarpaulin. Under the neck 2 of each tank vertically between the bottom and the bottom hang the pipe 3, which consists of separate sections 4. To prevent raw sugar

Cover all the valves of the tanks. Load sugar mechanisms, such as coastal conveyors. In this case, the pipes 5 are given oscillatory movements by the vibrators 5. After loading the filler cap 2 of the tank is hermetically sealed. For the ballasting of a vessel, separate unloaded tanks are used, for example, central / - // and airborne / a, / b, ///, VII. The temperature of the water in adjacent tanks is maintained within the temperature of the raw sugar.

During the voyage, the cargo in the tank is periodically ventilated depending on the difference in temperature between the dew point of the outside air, the temperature of the cargo and the hull of the vessel, and when equilibrium humidity of the sugar and air is observed. Sugar is unloaded by suction pipes 6 with a diameter of at least 200 ml1 through necks 2 and pipes 3. The tank is cleaned from the remnants of raw sugar with hoses, pipe 3 mines. During unloading, vibrators are turned on as needed (to destroy load arches).

Electric powered vibrators 5 that are fed by wire are fastened to the lower part of the pipes 3, which are fastened with fasteners 7 in tanks before loading. Below and above the pipes there must be free space for the goods to enter. When loaded, the pipes are closed with caps 8, and the cargo supplied by the conveyors 9 is freely scattered in the tanks, having an angle of repose in them. When vibrators are turned on, the angle of repose is significantly reduced, which eliminates the need for stowing the load inside the tanks. When unloading, the covers 3 are removed from the covers and the suction pipes 6 of the pneumatic supercharger are removed in them, which select a load from under the pipes. The vacated space is continuously filled with a load discharged from the upper layers.
