Description

Cabin cleaning process for viscous materials of bulk carrier Technical Field The invention belongs to the field of bulk carriers, and particularly relates to a cabin cleaning process for viscous materials of bulk carriers. Background Bulk carriers are short for bulk carriers and are specially used for transporting non-packed goods, such as grains, coal, ore sand, salt, cement and the like. The bulk cargo ship is of a single deck tail type structure with the cross section of the cargo hold being octagonal so as to be convenient for loading and unloading, and the bulk cargo ship has a large cargo hold volume because the bulk cargo has single type, low separation requirement on cabins and large specific gravity difference due to the fact that the bulk cargo is single in type and not prone to extrusion, and the bulk cargo ship is loaded and transported in a box mode. Bulk cargo is usually discharged after being piled up through a loader or a pusher falling into the cargo hold and a bulk cargo grab bucket, but the bulk cargo is difficult to clean when being completely cleaned by means of tools such as brooms and spades, especially the residues of the cargoes adhered to the bulkhead, and the bulk cargo is difficult to clean when being cleaned by the bulkhead due to the fact that the cargo hold is large in volume and high in bulkhead, the whole cleaning operation time is 8-12 hours, 10-20 workers are different, the consumed time is long, the cleaning efficiency is low, viscous materials are not easy to clean when being remained on the bulkhead, and the recovery rate is low. Disclosure of Invention The invention aims to overcome the defects, and provides a cabin cleaning process for viscous materials of bulk carriers, which can quickly and efficiently realize cabin cleaning of the viscous materials and improve the recovery rate of the materials. The invention aims at realizing the cabin cleaning process of viscous materials of bulk cargo ships by the following technical scheme, which comprises the following specific steps: S1, bulk cargos piled in a cargo cabin are fed into a conveying belt positioned at the bottom of the cargo cabin through a hydraulically operated switch gate, are conveyed to the head part or the tail part of a bulk cargo ship through the conveying belt, are lifted to the deck height of the bulk cargo ship through a belt conveyor, and are conveyed to the shore through the conveying belt on a discharging arm; S2, scraping materials on the bulkhead of the cargo hold from top to bottom through a grab bucket machine, enabling the scraped materials to fall into the bottom of the cargo hold along with the action of self gravity, intensively grabbing the scraped materials at the bottom of the cargo hold by the grab bucket machine, then conveying the scraped materials onto a conveying belt on a discharging arm from bottom to top, enabling the grab bucket machines to circulate for multiple times and cooperate with each other, enabling the materials adhered to the surface of the bulkhead to be uniformly conveyed onto the conveying belt of the discharging arm, and then conveying the materials onto a shore through the conveying belt on the discharging arm; S3, circularly beating the materials to the bulkhead of the cargo hold through a plurality of high-pressure gases, enabling the materials adhered to the bulkhead to fall to the bottom of the cargo hold, gathering the materials at the bottom of the cargo hold, and then delivering the materials to the shore through a grab bucket machine and a conveyer belt of a discharge arm; S4, pumping high-pressure water into the cabin wall and the bottom of the cargo cabin, flushing the residual materials on the cabin wall and the bottom of the cargo cabin, and mixing the materials with the high-pressure water to the bottom of the cargo cabin; S5, pumping and pressing the mixed materials and high-pressure water in the cargo hold into a storage cylinder on a deck through a high-pressure pump, carrying out solid-liquid separation on the storage cylinder, treating the separated wastewater, discharging no pollution, drying the separated solid materials, and conveying the dried solid materials to the shore for storage; S6, introducing high-pressure gas into the cargo hold to carry out air drying, and carrying out quick drying treatment on the interior of the cargo hold.
