Preparation device of deck covering for ship

Abstract

The invention discloses a preparation device of a deck covering for a ship. The preparation device comprises a circular tube-shaped pushing cavity, wherein two ends of the pushing cavity are respectively provided with a feed inlet and a discharge outlet, a screw propulsion rod is coaxially arranged in the pushing cavity, a screw surface of the screw propulsion rod is provided with multiple scraper blades extending outwards, the mounting position of each scraper blade is adjustable, the scraper blades are arranged along the axial direction of the screw propulsion rod, the outer edge of each scraper blade and the inner wall of the pushing cavity form clearance fit, and the inner wall surface of the pushing cavity and the surface of the screw propulsion rod are provided with smoothing layers; by rotating the screw propulsion rod, various raw materials including a viscous material can be pushed to the discharge outlet from the feed inlet in sequence, and a viscous mixture adhered to the inner wall of the pushing cavity and formed by mixing various raw materials can be scraped off by the scraper blades, and is also pushed to the discharge outlet, so that the raw materials are prevented from remaining in a production device, and accurate metering is realized.

Description

technical field [0001] The invention relates to the technical field of production of marine deck coverings, in particular to a preparation device for marine deck coverings capable of improving the ratio accuracy of raw materials. Background technique [0002] In facilities such as ships and offshore drilling platforms, it is often necessary to carry out heat insulation, rust prevention, corrosion prevention and fire prevention treatment on cabins and decks. In order to protect cabins and decks from fire, smoke, gas and water, it is usually necessary to lay marine deck coverings on the cabin floor and deck surface. [0003] Marine deck coverings are generally made by fully mixing raw materials including latex, powder and aggregate in a certain proportion. Since marine deck coverings contain flame retardant and thermally insulating materials, marine deck coverings form a fire-resistant covering when applied to a ship's deck surface. Marine deck coverings can improve the heat...

Problems solved by technology

These situations will make it difficult to ensure the proportioning accuracy of the raw materials falling into the mixing tank, and cause the binders to mix between different batches of materials, and lead to instability in the quality of the finished dressing after mixing

[0006] What's more, some of the batch materials accumulated on the inner wall of the push barrel will be bonded and solidified during the production interval, resulting in uneven shrinkage of the push channel diameter in the push barrel

This will not only affect the normal push of raw materials, but also scratch the screw and cause damage to the screw in severe cases.

[0007] In addition, although the gap between the outer diameter of the screw and the inner wall of the push barrel can be reduced by simply increasing the outer diameter of the screw, due to the large difference in particle size between different raw materials, when conveying raw materials with larger particle sizes , this method will still become difficult to apply

It will be more difficult in terms of economy and operation to match raw materials with different particle sizes with screws with suitable outer diameters.
