Example Embodiment

[0032] Example 1:

[0033] refer to figure 1 The present invention provides a technical solution, a device that prints no burn bricks using the river lake in the bottom mud 3D, including the test bench 1, the model groove 2, the moving portion 3, the feed portion 4, the print nozzle 5, and the controller 6; The model slot 2 is disposed on the experimental platform 1, the feed unit 3 is connected to the print pad 5, and the controller 6 is used to control the moving unit 3, the feed portion 4, and the print nozzle 5;

[0034]The moving unit 3 includes a ring slide rail 7, a first slide rail 8, a first mobile device 9, a second sliding rail 10, a second mobile device 11, a third slide rail 12, a third mobile device 13, and a fourth mobile device 14. The annular slide 7 is a closed annular orbit consisting along the test bench 1, and the annular slide rail 7 is fixed to four support columns at the bottom of the test bearing 1; the first slide rail 8 is disposed in the vertical direct...

Example Embodiment

[0039] Example 2:

[0040] refer to Figure 1-6 The present invention provides a technical solution, a method of printing the burn bricks, using a river lake sessate, using a device for printing the burn bricks with the river lake in Example 1, including the following steps:

[0041] First, the material is prepared: the bottom of the river lagoon is pulpatically, and then the submerged river lake sessate is stirred with the curing agent, the appliance is stirred and loaded into the stirring cell, add water, aggregate to obtain a 3D printing substrate;

[0042] Second, three-dimensional modeling: use 3D modeling software to establish the size of the three-dimensional stereoscopic model of the flask brick; the three-dimensional stereoscopic model of the flask brick includes a six-roll slope tile 20, a honeycomb slope tile 21, a self-eated wall block 19 and Interlocking sliding tile 22, the self-eated wall block 19 is a trapezoidal structure, the six-prism slope tile 20 is a six-ride ...

Example Embodiment

[0048] Example 3:

[0049] refer to Figure 1-6 On the basis of Example 2, the 3D printing substrate was made of the following mass percentage of raw materials: 60% of the river lake, 18% curing agent, 15% natural stone, 5%, high-efficiency water reducer 2%, each The sum of the components of mass is 100%. The bottom mud is not required to be dehydrated. The water content is 60% by weight, and the resulting 28D 3D print free burn brick is intensified. Its compressive strength is 15MPa, and the "Hazardous Waste Identification Standard Leaching Toxicity Different" (GB5085 .3-2007).

Abstract

The invention discloses a device for 3D printing of baking-free bricks through river and lake bottom mud and a manufacturing method, and belongs to the technical field of 3D printing. The device comprises a test bearing platform, a model groove, a moving part, a feeding part, a printing spray head and a controller; the model groove is arranged on the experiment bearing platform, the feeding part is connected with the printing spray head, and the controller is used for controlling the moving part, the feeding part and the printing spray head; a river and lake bottom mud baking-free brick is manufactured through in-situ material taking on site and 3D printing, and the links of transportation and stockpiling are reduced; and a three-dimensional model of the river and lake bottom mud baking-free bricks is flexibly designed, the three-dimensional model comprises a self-embedded soil retaining block in a slope protection retaining wall structure in roadbed engineering, a hexagonal block in a slope protection surface and a honeycomb grid or chain type slope protection brick body model, resource utilization of the river and lake bottom mud is achieved, and the three-dimensional model is diversified in form, flexible in application, convenient and fast to construct and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and relates to a device and a manufacturing method for 3D printing burn-free bricks using river and lake bottom mud. Background technique [0002] The amount of sediment produced by river or lake bottom dredging in my country is more than 1 billion cubic meters per year. These river and lake sediments are a natural resource that is abandoned but can be reused. The main chemical composition of river and lake bottom mud is composed of quartz, clay minerals and feldspar minerals, and also contains a small amount of carbonate, trace sulfate, phosphate and organic matter, which belongs to silicate raw materials; it can replace clay and shale raw materials ecological resources. The main sources of river and lake bottom mud are: one is the minerals naturally formed by the sediment brought by rainwater, river and lake water movement, and floods; the other is the waste discharged from industry and aq...
