Description

TECHNICAL FIELD

[0001] The utility model belongs to concrete production equipment technical field, especially, relate to a kind of pre-fusion equipment for concrete additive. BACKGROUND

[0002] Concrete is the most common material in the construction industry, and when producing concrete, first put the concrete additive into the mixing tank or reaction kettle, so that the additive is pre-fused, and then put the concrete raw material into the mixing tank or reaction kettle again for mixing and stirring after the additive is pre-fused, and the finished product is obtained after the reaction is completed. Or use a pre-fusion device to pre-fuse the additive, and then put the pre-fused additive into the mixing tank or reaction kettle that is stirring the concrete raw material, to obtain the finished product of usable concrete.

[0003] A Chinese patent application (or patent) with publication number CN217341169U discloses a raw material pre-fusion device for concrete additive, which includes a pre-fusion tank. A stirring shaft is rotatably installed at the middle end of the inner bottom of the pre-fusion tank. A transmission drum is movably connected to the top surface of the stirring shaft. The utility model wraps two groups of transmission soft belts around the front and rear ends of the transmission drum. When the motor drives the stirring shaft to stir and disperse the raw materials in the pre-fusion tank, it also drives the transmission drum to wind the transmission soft belts, which in turn drives the two sliding plates and the cleaning scrapers installed on their surfaces to scrape and clean the inside of the pre-fusion tank. This avoids the adhesion of raw materials to the pre-fusion tank, reduces the energy consumption and manufacturing cost of the entire cleaning device, and is practical and suitable for wide application and use.

[0004] The above-mentioned raw material pre-fusion device for concrete additive is provided with a pre-fusion tank, which is a cylindrical tank with a support rod at the bottom. It is difficult to adapt to the use of concrete mixing tank or reaction kettle, and after the pre-fusion of the additive is completed, it needs to be taken out from the tank body and then put into the concrete mixing tank. This process may cause the pre-fused additive to be contaminated on the transportation equipment, resulting in a decrease in the actual use of pre-fused additive. In addition, the pre-fusion tank is also provided with a transmission soft belt, a sliding plate and a cleaning scraper. Through the linkage effect of the transmission soft belt and the sliding plate, the cleaning scraper moves up and down in the pre-fusion tank, achieving the effect of cleaning the additive attached to the inner wall of the pre-fusion tank. However, because the transmission soft belt, the sliding plate and the cleaning scraper are all installed in the pre-fusion tank, they will still come into contact with the additive. Therefore, during the pre-fusion process of the additive, there will be a lot of additive attached to the surface of the cleaning scraper, which cannot be cleaned. Moreover, the actual amount of pre-fused additive obtained is much smaller than the input amount, causing waste of raw materials. Therefore, we provide a pre-fusion equipment for concrete additive to solve the above-mentioned problems. Utility model content
