Description

Technical Field

[0001] This invention relates to the field of concrete brick preparation, specifically to a concrete brick foaming and mixing device. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks are a lightweight, porous building material made through a special process. They possess advantages such as lightweight, heat insulation, and fire resistance, and are widely used in modern construction. Their main raw materials are cement, stone, and fly ash, with the addition of a foaming agent. The lightweight characteristic is achieved through the filling of air bubbles.

[0003] Generally, the prepared mortar needs to be thoroughly mixed after the addition of the foaming agent. This mixing process usually requires the assistance of stirring to ensure that the bubbles generated by the foaming agent are evenly mixed in the mortar. However, during this stirring process, because the mortar has a high density and the bubbles have a low density, the bubbles tend to float to the surface of the mortar during stirring, causing foam to form on the surface of the final mixed mortar. This will affect the quality of the mortar when it is used later. Summary of the Invention

[0004] The purpose of this invention is to provide a concrete brick foaming and mixing device to solve the problems mentioned in the background art.

[0018] Please see Figures 1 to 8 The present invention provides a technical solution: a concrete brick foaming mixing device, including an outer cylinder 1 and an inner cylinder 2, wherein a cavity with an opening at the top is formed between the cylinder walls of the outer cylinder 1 and the inner cylinder 2, a support 3 is provided at the top of the outer cylinder 1, a stirring assembly 4 is installed in the support 3, and a circulation collection assembly 5 is connected to the stirring assembly 4. The mixing assembly 4 includes a motor 41 and a mixing blade 42. The bottom of the mixing blade 42 can scrape against the bottom surface of the inner cylinder 2. The motor 41 is installed in the bracket 3 and can drive the mixing blade 42 to rotate. Through the action of the mixing blade 42 driven by the motor 41, the mortar in the inner cylinder 2 is mixed evenly. The circulating collection component 5 includes a sticking plate 51 and a base plate 52. The sticking plate 52 is connected to the base plate 52 via a connecting ring 53. The sticking plate 51 can clean the foam on the surface of the mortar during foaming and mixing.

[0019] In this embodiment, the outer cylinder 1 is provided with feet at its bottom for supporting the outer cylinder 1.

[0020] In this embodiment, a guide rail is provided on the bottom surface of the inner cylinder 2. A guide block 421 is provided at the bottom of the stirring blade 42, and the guide block 421 is slidably connected to the guide rail to provide guidance for the rotation of the stirring blade 42.

[0021] In this embodiment, the stirring blade 42 is provided with stirring holes 422, the stirring blade 422 is mounted on the isolation cylinder 423, the isolation cylinder 423 is mounted on the drive shaft 424, the top of the drive shaft 424 is connected to the output shaft of the motor 41, and the stirring holes 422 are used to help the air bubbles mix evenly with the mortar.

[0022] In this embodiment, the edge of the adhesive plate 51 extends above the cavity, and a reset elastic pad is provided between the adhesive plate 51 and the upper end of the opening of the inner cylinder 1. A cleaning cotton pad is provided on the lower surface of the adhesive plate 51, and an air hole 511 is provided above the cleaning pad on the adhesive plate 51. The lower part of the adhesive plate 51 is connected to the top of the isolation cylinder 423 through an adapter 57. The foam collected by the adhesive plate 51 will be concentrated and converged and finally flow into the cavity to complete the collection.

[0023] In this embodiment, the base plate 52 includes an inner plate 521 and an outer plate 522. The lower surface of the base plate 52 is an arc shape with the height decreasing from the center to the edge. The base plate 52 is provided with air holes 523. The outer edge of the outer plate 522 is provided with a sealing plate. The arc shape is conducive to the flow of the collected bubbles to the cavity position.

[0024] In this embodiment, a connecting wall 54 is provided on the inner edge of the inner plate 521. A pressing ring 55 is connected to the connecting wall 54 and is connected to the transmission shaft 424 through the pressing ring 55. A pressing platform 551 is provided on the pressing ring 55. A pressure receiving ring 56 is provided directly below the pressing ring 55 and mounted on the adhesive plate 51. The pressure receiving ring 56 is provided with a pressure receiving platform 561. When the pressing ring 55 rotates and the pressing platform 551 encounters the pressure receiving platform 561 on the pressure receiving ring 56, it can press the adhesive plate 51 downward, so that the cleaning cotton pad on the adhesive plate 51 can touch the foam on the mortar surface. Through the porous material characteristics of the cleaning cotton pad, the foam is absorbed, and the cleaning purpose is achieved.

[0025] In this embodiment, the top of the connecting ring 53 is provided with a piston plate 531. The piston plate 531 changes the air pressure in the bottom plate 52 by moving up and down. When the adhesive plate 51 moves up and down, the connecting ring 53 can drive the piston plate 531 to move up and down. By changing the air pressure, the foam adsorbed by the cleaning cotton pad is adsorbed between the adhesive plate 51 and the bottom plate 52 through the air hole 1 511 and the air hole 2 523 until it gathers into a stream of water and is then discharged into the cavity.

[0026] Working principle: First, a sufficient amount of mortar is injected into the inner cylinder 2, followed by the injection of a foaming agent. Then, the mortar is thoroughly stirred by the stirring blades 42 to ensure that the mortar and air bubbles are fully mixed. During this process, because the pressing ring 55 is connected to the drive shaft 424, the pressing ring 55 will rotate. When the rotating pressing ring 55 encounters the pressure plate 561 on the pressure ring 56, it can press down on the sticking plate 51, allowing the cleaning cotton pad on the sticking plate 51 to come into contact with the foam on the mortar surface. Through the porous material characteristics of the cleaning cotton pad, the foam is adsorbed, achieving the purpose of cleaning. The air bubbles adsorbed on the cleaning cotton pad will burst, and under the action of the piston plate 531 moving up and down, the liquid produced by the bursting will be drawn into the space between the sticking plate 51 and the bottom plate 52 by the air hole 1 511 and the air hole 2 523 until it gathers into a stream of water and is then discharged into the cavity.

[0027] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative and not exhaustive. All modifications within the scope of this invention or its equivalents are included in this invention.
