Description

Manufacturing device for carbon dioxide carbonized brick body

Technical Field

The utility model belongs to civil engineering device class, concretely relates to making devices of carbon dioxide carbonization brick body.

Background

With the continuous development of urbanization, a large number of urban and rural buildings are removed, and a lot of the removed buildings are clay bricks. In the last 50 years, China has produced 200 hundred million m in total³Left and right clay bricks, which are discarded along with the removal, accounting for about 30-50% of the construction waste. The waste clay bricks have abundant sources, and the waste bricks are transported to suburbs or villages without any treatment, some waste bricks are directly used as filling materials of ordinary road foundations, some waste bricks are treated in an open-air stacking or landfill mode, and the good application of building wastes is not realized. The treatment modes not only occupy a large amount of land, but also scatter a large amount of dust and dust in the clearing and stacking processes, thus aggravating environmental pollution and causing more and more pressure on social environment. When an old building is dismantled, a large amount of brick body materials are needed for the construction of a new building, for example, a partition wall of a house building, a sidewalk or a park ground and the like need a large amount of brick bodies, and if waste building waste can be used for manufacturing the brick bodies, the utilization value of the building waste is greatly improved.

The traditional brick mainly uses clay as a main material and is made into bricks with different colors by the processes of molding, drying, high-temperature kiln calcination and the like. The manufacturing installation of traditional brick body mainly divide into box kiln and tunnel cave: the box-type kiln comprises a structural kiln, an injection port, an exhaust port and a heating device, wherein the structural kiln is composed of a refractory wall and has a space for loading brick bodies; the inlet port supplies material into the structure, the exhaust port exhausts combustion gas from the kiln, and the heating device is mainly used for firing bricks. The device has a complex structure, cannot be heated again when entering a carbon coating process, and has long carbon coating time and low efficiency. The tunnel kiln is composed of a preheating part, a burning part and a cooling part, and also comprises a carbon car, but the device has a complex structure and consumes high energy. For example, the invention patent CN 111499348A "a process for producing a baked brick" discloses a method for preparing a baked brick, but malodorous gas is generated in the processes of sludge drying and raw material aging, dioxin which is harmful to human beings or animals and toxic gas can be generated when the brick body is baked in a baking kiln, and the brick making environment is not friendly; the method utilizes the energy of the coal cinder and the added wood chips to continuously sinter the brick body for 3 days at the temperature of 950-1000 ℃, and a large amount of wood is consumed. The invention patent CN 111484263A "method for preparing novel baked brick from construction waste" discloses a method for more fully and uniformly stirring raw materials for preparing baked brick, although the method improves the quality of the baked brick, the method is similar to the method of the invention patent CN 111499348A, the method adopts a sintering process to prepare the baked brick, the firing time is long, the resource consumption is large, and the sustainable development is not facilitated.

In the later development, baking-free bricks are also produced, and the used materials mainly comprise cement, industrial slag, steel slag, sludge and the like. For example, patent CN 107879704A "A preparation method of a composite steel slag carbonized brick" discloses a method for treating and making bricks from steel slag, which utilizes kerosene to ignite and promote the oxidation-reduction reaction of unoxidized metal substances in steel slag, improves the porosity of steel slag to make the hydration reaction more sufficient, and utilizes the properties of carbomer that gel is coagulated in an alkaline environment and the gel is dissolved in an acidic environment to fully carbonize the steel slag. The method comprises a plurality of procedures such as ball milling, combustion cooling, steam pressure curing, vinegar smoking, carbonization and the like, and the brick making method is scientific, but has low brick making efficiency because the brick making steps are complicated, the addition agent is more, the process is complex, more dispersing devices are required. The invention also discloses a device for recycling construction waste to make bricks, as the invention patent CN 111688014A 'a construction waste brick making device', the device comprises a hammering cavity, a screening magnetic separation component, a river sand stirring cavity, a sand grinding cylinder and a brick forming chamber, the strength of the extruded brick body mainly comes from stone and river sand separated from the construction waste, but the stone is difficult to avoid being damaged in the sorting and hammering process, and the brick body also contains excessive soil materials which can influence the strength of the brick body, but in practice, the construction waste contains a large amount of soil materials, for example, the proportion of waste clay bricks in the construction waste is often as high as 30%, and the engineering requirements are difficult to be achieved by using a gelling agent and other strength reinforcing agents. In a word, the existing method has complicated device steps, large construction amount, strict requirements on additives and low brick forming strength.

The magnesia carbonization technology appeared in recent years proves that the magnesia carbon brick is remarkably excellent, and compared with the common brick body preparation technology, the magnesia carbon brick has the advantages of small resource consumption, less greenhouse gas emission, short preparation period, high strength, good water resistance and the like. However, the existing carbonization technology is still imperfect and has a plurality of problems. For example, the invention patent CN 104326736B, a simple method for preparing magnesia fiber brick, discloses a simple method for preparing magnesia fiber brick by using cotton-containing cloth as a template, but the method requires that the brick-shaped cloth is put into a tunnel kiln, then rapidly heated to 400-800 ℃, and then slowly heated to 1100-1600 ℃ for sintering for 0.5-1 h, the method has higher requirements on construction machinery, and the sintering method must consume a large amount of energy for preparing the magnesia fiber brick. For example, in patent CN 105837143B, "a method for preparing an activated magnesium oxide carbonized block", the invention uses cement, crushed stone, sand and other materials as raw materials, and although the strength and quality of the block are ensured, the problems of cost and difficulty in obtaining materials are not considered, and environmental pollution is directly or indirectly caused by using a large amount of portland cement; the invention only discloses a method and a technical scheme for preparing a magnesium oxide building block, and a specific and efficient manufacturing device is not provided. In addition, no matter which technique is adopted for making the brick, the prior documents have the problems of difficult demoulding, slow strength increase, poor environmental benefit and the like in the preparation process of the brick body, the brick body is still difficult to directly take out from a cavity or can not freely fall off after the injection molding of the brick machine, the brick body can fall off only by adding a demoulding procedure, and the brick making efficiency is greatly reduced.

To sum up, to the existing problem about brickmaking method and brickmaking device of existing file, the utility model discloses combine the advantage of building rubbish wastes material utilization and magnesium oxide carbonization technique, solve the brickmaking in-process simultaneously and can appear the difficult problem of drawing of patterns, this has direct and realistic meaning to improving brickmaking efficiency, protection ecological environment.
