[0002] Foamed concrete is a new type of lightweight thermal insulation material containing a large number of closed pores. It is produced by mechanically foaming a foaming agent using a foaming machine system, uniformly mixing the foam with cement slurry, and then allowing it to cure naturally. It features lightweight, thermal insulation, heat insulation and fire resistance, sound insulation, and frost resistance.

[0003] In the preparation of foamed concrete, problems often arise such as foam defoaming, foam breakage during mixing, and inaccurate addition of foam. A foamed concrete mixing device is a machine that thoroughly mixes raw materials such as cement, foam, and water. Existing foamed concrete mixing devices are complex in structure. To address the difficulties in preparing foamed concrete in construction environments with small project scales, limited space and conditions for large-scale foamed concrete preparation, difficulties in transporting and installing large fixed mixing equipment, or frequent changes in work sites, it is necessary to provide a foamed concrete preparation device that solves the aforementioned engineering and technical problems.

[0004] The present invention aims to provide a foamed concrete preparation device that can meet the needs of small-scale foamed concrete preparation, is suitable for environments with small construction sites or unsuitable for large-scale foamed concrete preparation, and has the advantages of small size and simple use.

[0005] The technical solution adopted in this application is as follows:

[0006] A small-batch foamed concrete preparation apparatus includes a base frame, on which a mixing tank, a mixing mechanism, and a foaming mechanism are mounted. The mixing tank has a foam inlet and a feed inlet for adding raw materials. The foaming mechanism generates foam and sends the generated foam into the mixing tank through a foam outlet pipe from the foam inlet. The mixing mechanism mixes the raw materials and foam in the mixing tank evenly.

[0007] In the foamed concrete preparation apparatus described above, the mixing tank is rotatably mounted on the base frame, and a positioning mechanism is provided between the mixing tank and the base frame. The positioning mechanism is used to fix the mixing tank on the base frame or to release the relative fixation between the two.

[0008] As described above, in a foamed concrete preparation apparatus, the positioning mechanism includes a positioning hole provided on the mixing tank, and a positioning pin that can pass through the base frame and be movably positioned and connected to the positioning hole.

[0009] As described above, a foamed concrete preparation apparatus includes a foaming mechanism comprising a foaming machine for generating foam and a foaming agent storage box disposed on one side of the foaming machine for supplying foaming agent thereto. The foaming machine is connected to the foaming pipe, and a flow meter is provided on the foaming pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model provides a foamed concrete preparation device, including a base frame, a mixing tank, a mixing mechanism and a foaming mechanism, wherein the foaming mechanism is used to generate foam and transport it into the mixing tank, and the mixing mechanism mixes the raw materials and foam in the mixing tank evenly. This device can meet the requirements of small-scale foamed concrete preparation and is suitable for environments with small construction sites or unsuitable for large-scale foamed concrete preparation. It has the advantages of small size and simple use.

[0018] 2. The foaming mechanism used in this utility model can accurately control the amount of foam entering the mixing tank through a flow meter, so as to achieve a precise ratio of foam and concrete. This can greatly improve the performance of foamed concrete and ensure the quality of the project. The foaming machine directly introduces the prepared foam into the mixing tank through the flow meter and the foam outlet pipe to achieve full mixing with the concrete. This can avoid the foam defoaming caused by external environmental factors (such as sunlight and dust) and affect the foam performance, thereby producing foamed concrete with certain performance requirements.

[0019] 3. The mixing tank used in this utility model is rotatably mounted on the base frame, and a positioning mechanism is provided between the mixing tank and the base frame. The positioning mechanism can be used to fix the mixing tank on the base frame or to release the relative fixation between the two. After the foamed concrete is prepared, the mixing tank can be manually rotated to discharge the foamed concrete remaining at the outlet of the mixing tank through the discharge pipe. This solves the practical engineering problems in actual application, such as the large amount of foamed concrete remaining at the bottom of the mixing tank that cannot be discharged, as well as the foam breakage and inaccurate foam addition caused by transporting the prepared foam from the foaming machine to the mixer. It also solves the problem of the foamed concrete remaining at the outlet of the mixing tank that cannot be completely poured out.

[0020] 4. The foamed concrete preparation device proposed in this utility model can solve the problem of difficulty in preparing foamed concrete in some construction environments where the project scale is small, there is no conditions or space for large-scale foamed concrete preparation, it is difficult to transport and install large fixed mixing equipment, or it is necessary to frequently change the workplace.
