Embodiment 1

[0057] This embodiment proposes a method for filling insulation cotton suitable for insulation boxes based on any of the above implementations or a combination thereof:

[0058] In the above embodiment, when the vibrating component is used to vibrate and enrich the insulating box of the vibrating station, the specific operation steps can be:

[0059] (1) After the insulating box is filled with insulation cotton at the filling station of the insulating box filling roller table 3, the filling effect is detected and processed by distance sensors and other equipment;

[0060] (2) Then, the qualified insulation box after the detection is transferred from the insulation box filling roller table 3 to the vibrating roller table 1, and the insulation box is stopped at the position directly above the vibrating sieve plate 14;

[0061] (3) Raise the vibrating lifting member 13 to drive the vibrating sieve plate 14 to lift, so that the vibrating sieve plate 14 carries the insulating box a...

Abstract

The invention relates to a low-temperature insulation box heat insulation cotton filling method for a liquefied natural gas ship liquid cargo maintenance system. An insulation box to be filled is conveyed to a filling station through a filling roller way, after the insulation box is filled with the heat preservation cotton by an insulation cotton filling mechanism, and then the insulation box is transferred to a vibration station on a vibration roller way for vibration filling treatment. Compared with the prior art, the method has the advantages that the compactness degree of the heat preservation cotton is more uniform, the filling defects such as over-tightening, unevenness, edge warping, corner pressing and the like generated in the filling process are reduced, and the high quality andthe consistency of the filling effect are realized and ensured.

Description

technical field [0001] The invention belongs to the technical field of insulation cotton filling in insulation boxes, and relates to a method for filling insulation cotton in a low-temperature insulation box (hereinafter referred to as the insulation box) of a liquid cargo maintenance system for liquefied natural gas ships. Background technique [0002] For the low-temperature insulation box of the liquid cargo maintenance system used by liquefied natural gas ships, it is a hollow box that is divided into multiple longitudinal compartments by vertical partitions of multiple insulating boxes. Insulation cotton material with the same cross-section. In order to ensure the insulation effect of each box, the filling of the insulation cotton in the box must be tight and uniform without gaps. The existing artificial filling method is labor-intensive, low in efficiency, and the filling quality cannot be guaranteed, which is likely to cause quality problems such as edge warping, pre...
