AI Technical Summary

Benefits of technology

This new technology uses sea sand that can be used for making brick without being too sensitive or easily damaged during manufacturing process. It does this through its unique properties such as low water absorption capacity, strong resistance against bending stress, ease with cracks when breaking off from previous products made at home, and ability to absorb more moisture than existing materials while still maintain their strengths under harsh conditions like seawater. Overall, it provides technical benefits compared to traditional methods.

Problems solved by technology

The technical problem addressed in this patented text relates to finding ways to utilise resources found at sea that were previously wasted due to overuse caused by sedimentation during excavations. This could lead to environmental damage if no suitable methods exist available.

Embodiment 1

[0017] Use East China Sea silt to make load-bearing hollow bricks that meet the GB13544-2000 national standard. The specification is 240×115×90mm, a circular hole with a diameter of 20mm, and a hole rate of 25%. The specific steps are as follows:

[0018] ⑴Excavation: Excavate and pile up sea silt and sea sand at the beaches along the East China Sea and Haikou beaches at the same time;

[0019] ⑵Weathering: The accumulated sea silt and sea sand are naturally dehydrated and weathered for 6 months;

[0020] ⑶ Ingredients: the weathered sea silt and sea sand are mixed in proportion to form mud: sea silt: sea sand = 50: 50 parts by weight, and then homogenized by a twin-shaft mixer, placed in the shed for 72 hours of aging Change

[0021] ⑷ Purification: The aged mixed mud is filtered through a purification extruder to remove impurities such as stones, plant roots, and then crushed by a roller to finely crush small impurities such as shells in the filtered mud;

[0022] ⑸ Billet making: Us...

Embodiment 2

[0026] Use East China Sea sludge to make sintered hollow bricks that meet the GB13545-2003 national standard. The size is 290×190×90mm, the holes are arranged in an orderly manner, and the hole rate is 40%. The specific steps are as follows:

[0027] ⑴Excavation: Excavate and pile up sea silt and sea sand at the beaches along the East China Sea and Haikou beaches at the same time;

[0028] ⑵Weathering: The accumulated sea silt and sea sand are naturally dehydrated and weathered for 8 months;

[0029] ⑶ Ingredients: The weathered sea silt and sea sand are mixed in proportion to form a mud material: sea silt: sea sand = 55:45 parts by weight, and then homogenized by a twin-shaft mixer, placed in the shed for 96 hours of aging Change

[0030] ⑷ Purification: The aged mixed mud is filtered to remove impurities such as stones and plant roots through a purification extruder, and then a fine crushing roller is used to finely crush small impurities such as shells in the filtered mud;

Embodiment 3

[0035] Using East China Sea silt to make sintered hollow blocks that meet the GB13545-2003 national standard, the size is 290×290×190mm, the holes are arranged in an orderly manner, and the porosity is 40%. The specific steps are as follows:

[0036] ⑴Excavation: Excavate and pile up sea silt and sea sand at the beaches along the East China Sea and Haikou beaches at the same time;

[0037] ⑵Weathering: The accumulated sea silt and sea sand are naturally dehydrated and weathered for 10 months;

[0038] ⑶ Ingredients: The weathered sea silt and sea sand are mixed in proportion to form a mud: sea silt: sea sand = 60: 40 parts by weight, and then homogenized by a twin-shaft mixer, placed in the shed for 96 hours of aging Change

[0039] ⑷ Purification: The aged mixed mud is filtered to remove impurities such as stones and plant roots through a purification extruder, and then a fine crushing roller is used to finely crush small impurities such as shells in the filtered mud;

Abstract

The invention discloses a method for manufacturing brick by utilizing sludge from the East China Sea. The method includes that sea sludge and sea sand at the coastwise beach and sea port beach of the East China Sea are excavated and piled, natural dehydration weathering is carried out, sea sludge and sea sand which are subject to weathering are mixed into pug in proportion, and stirring, homogenizing, ageing, purifying, fine grinding, blanking, drying and roasting are carried out. The invention overcomes the defects that coefficient of drying sensitivity is high, plasticity index is high, brick body is easy to crack and shrink rate is high which are caused by the manufacturing in the prior art, natural resource is utilized and waste material is changed into things of value while reaching the national standards GB13544-2000 and GB13545-2003, thus not only saving a mass of tilled land resource but also solving the problems in wall material reformation and building energy conservation emission reduction project in brick making industry in coastal area.
