Description

Technical Field

[0001] The utility model relates to the field of metering equipment, in particular to an automatic metering device for raw materials. Background Art

[0002] Aerated aluminum powder is also called aluminum powder paste for aerated concrete. Its main purpose is to release gas during the chemical reaction between aluminum powder, silicon dioxide and quicklime during the production process, so that a porous structure is formed inside the produced concrete blocks. In the batching process of aerated concrete block production, the aerated powder is added to the aluminum powder slurry mixing tank, and after sufficient mixing, it is put into the aluminum powder slurry weighing scale, and finally put into the pouring mixer together with quicklime, gypsum, fly ash and other raw materials. The aluminum powder in the aluminum powder paste can react with alkaline substances in the aerated concrete slurry to release hydrogen and generate bubbles, so that the aerated concrete slurry expands to form a porous structure.

Although the device can play the role of metering addition, it has some shortcomings. The main one is that during the falling process of the material, the weight of the dynamically falling material obtained by the weighing scale is not accurate due to the gravity caused by the falling material plus the falling speed.

[0024] The raw material automatic metering device comprises a quantitative material storage core 2 which is rotatably arranged in a discharging barrel 1, and after a feed port 3 is connected with a first discharging hole 51, material feeding is realized. After the storage space of the quantitative material storage core 2 is filled, the feed port 3 is cut off from the first discharging hole 51 by rotation, so that a discharging hole 4 is connected with a second discharging hole 61, and material discharge is realized. The utility model realizes quantitative material taking through the quantitative material storage core 2, and compared with the metering scale in the prior art, the cost can be effectively saved, and there is no need to read metering data, and the quantitative acquisition of materials is realized by volume, and the metering is more accurate.

[0025] In some embodiments, there is one feed port 3 and one discharge port 4. One feed port 3 and one discharge port 4 can realize the quantitative material storage core 2 for taking materials, and is used for taking a small amount of materials.

[0026] In this embodiment, the quantitative material storage core 2 is a cylinder, and there are multiple feed ports 3 and discharge ports 4, and there is a distance between adjacent feed ports 3 and discharge ports 4.

[0027] The first discharge hole 51 and the second discharge hole 61 are multiple and correspond to the feed port 3 and the discharge port 4 .

[0028] It also includes a driving mechanism, which includes a driving member 7 and a rotating shaft 8 connected to the power output end of the driving member 7, and the rotating shaft 8 is connected to the quantitative material storage core 2.

[0029] The quantitative material storage core 2 includes a central connecting shaft 21 , the feed port 3 and the discharge port 4 are arranged on the periphery of the central connecting shaft 21 , and the rotating shaft 8 is connected to the central connecting shaft 21 .

The discharge of raw materials is realized by pushing and pulling the discharge plate.

[0032] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
