Description

Technical Field

[0001] The invention relates to the technical field of building insulation board production, and in particular to a foamed ceramic forming device and method. Background Art

[0002] Foamed ceramics are made of clay tailings, ceramic fragments, river silt, ceramic solid waste, etc. as the main raw materials. By adding special foaming agents, wet or dry material preparation, and then fabrication and high-temperature kiln baking, it is a high-porosity, uniform closed-cell ceramic material. It is regarded as a new high-tech environmentally friendly material that "turns waste into treasure". It has the advantages of light weight, high strength, fire resistance, waterproof and moisture-proof, thermal insulation, sound insulation and noise reduction, green environmental protection, stable performance, and good weather resistance.

[0003] The production process of foamed ceramics requires grinding various raw materials into stone powder, adding a foaming agent and mixing them evenly, pouring the mixture into a mold, and forming it through pressure or vibration. The formed body is placed in a kiln and baked at a high temperature of about 1200°C for about 10 hours to make the body spontaneously ignite, melt and foam to form a closed-cell ceramic material with high porosity. However, in the process of pouring the mixture into the mold, it is necessary to prevent too many air gaps inside the mixture, as too many air gaps will reduce the molding quality of the foamed ceramics.

[0004] A Chinese patent with authorization announcement number CN118003431B discloses a foamed ceramic insulation board forming device, which includes: a mixing component, the mixing component includes a mixing bin and a mixing and vibrating rod, wherein a conveying component for quantitatively conveying the mixed material is provided in the mixing bin, and the mixing and vibrating rod is provided with at least two upper and lower parts for rotating and stirring the mixed material, and the two rotation directions are opposite, and each turns so that the vibrated and stirred mixed material is thrown toward the quantitative conveying component, and the quantitative conveying component is arranged between the two mixing and vibrating rods.

[0005] The above patent uses a conveying frame that matches the size of the foamed ceramic insulation board to quantitatively convey the mixture, and then adopts a direct overall instantaneous pouring method to fill the mold frame. It is not easy to have local unevenness, especially for larger insulation boards. It can well ensure the uniformity of various parts inside the insulation board, and does not require the assistance of specific metering devices for the transportation of materials. At the same time, it ensures that the air gap inside the output mixture has been actively discharged to a large extent, and the mixture itself in the conveying frame is uniform and stable.

[0006] However, in the process of pouring the mixture from the conveying frame into the mold in the above patent, the mixture is easy to adhere to the conveying frame, resulting in the amount of mixture loaded into the mold being lower than the amount of mixture required to form a foamed ceramic insulation board, affecting the molding quality.

[0056] The foamed ceramic forming method according to the embodiment of the present invention is applied to the foamed ceramic forming device according to the embodiment of the present invention, comprising the following steps:

[0057] The first step is stirring and mixing. The powdered raw material and the foaming agent are filled into the mixer 1. The mixer 1 fully stirs the powdered raw material and the foaming agent to form a mixture. The mixer 1 pours the mixture into the lower silo 2.

[0058] The second step is to pour the material. The feeding conveyor belt 14 moves the mold 4 to the conveyor belt 32. The driving shaft 33 drives the conveyor belt 32 to rotate. The conveyor belt 32 moves the mold 4 to below the discharge port of the lower bin 2. The second driving member 13 drives the sealing plate 12 to be received into the lower bin 2, thereby opening the discharge port. The mixed material falls on the mold 4 from the discharge port under the action of gravity. At this time, the driving shaft 33 rotates back and forth, driving the conveyor belt 32 to rotate back and forth, so that the mold 4 moves back and forth in the front and back directions. During the movement of the mold 4, the mixed material falls on the mold 4 and is spread on the mold 4 as the mold 4 moves to form a layer of mixed material. During the pouring process, the lifting mechanism 52 drives the mounting seat 51 to move downward, and the first driving member 54 drives the screw rod 53 to rotate, so that the toggle plate 55 moves back and forth in the left and right directions. The toggle rod can toggle the material located in the center part of the mold 4 to the edge of the mold 4. By toggling the material, the edge of the mold 4 is filled densely to prevent empty material on the side of the mold 4. While the toggle plate 55 reciprocates in the left and right directions, the rotating assembly drives the toggle plate 55 to swing left and right, and the toggle plate 55 drives the stirring rod 6 to swing synchronously. The stirring rod 6 can stir the mixture in the mold 4 to reduce the air gap of the mixture in the mold 4. The stirring rod 6 stirs the single-layer mixture layer. Since the thickness of the single-layer mixture layer is thin, it is easier to reduce the air gap in the single-layer mixture layer. During the swinging process of the toggle plate 55, the scraper 10 swings synchronously with the toggle plate 55, and the scraper 10 always remains at the same height. The scraper 10 can scrape the upper surface of the mold 4 flat and wipe out the traces of the stirring rod 6 in the mixture. When the toggle rod swings to the lowest point, the stirring rod 6 will stop at the bottom surface of the mold 4 and push the mold 4 to move downward, so that the second elastic member 113 contracts and the limiting pin 11311 extends into the limiting hole 11321. After the toggle rod is rotated upward, the spring releases the elastic force, the limiting pin 11311 is squeezed into the first rod 1131, and the second elastic member 113 stretches. The second elastic member 113 pushes the vibrating upper plate 112 to move upward, and the vibrating upper plate 112 pushes the mold 4 to move upward, so that the mold 4 can collide with the lower hopper 2, thereby causing the mold 4 to vibrate. The mixture layer at the bottom of the mold 4 is further compacted by vibration, thereby reducing the air gap in the mixture.

[0059] After the mixture is fully spread on the bottom of the mold 4, the lifting mechanism 52 drives the mounting seat 51 to move upward, and drives the toggle plate 55 to move upward. The upward movement height is equal to the thickness of the mixture layer. Then the mold 4 moves in the opposite direction and lays the next layer of the mixture until the mold 4 is filled with the mixture.

[0060] In the third step, the conveyor belt 32 transfers the mold 4 filled with the mixed material to the discharge conveyor belt 15, and the discharge conveyor belt 15 moves the mold 4 filled with the mixed material to the next process.
