Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of stirring, and specifically relates to a retarder stirring and mixing equipment for sea sand concrete preparation. BACKGROUND

[0002] Because seawater contains a large amount of sodium chloride, magnesium chloride, magnesium sulfate and other salts, the above-mentioned salts are also wrapped in sea sand. When directly using untreated seawater and sea sand to mix concrete, it often leads to a series of problems such as a large advance in concrete setting time and a too fast loss of slump, which cannot meet the construction requirements. To solve the above-mentioned problems, the prior art uses the retarding and water-reducing components of the retarder to improve the problems of too fast setting and poor dispersion caused by directly using seawater and sea sand, and uses small molecules of sacrificial agents to slow down the too fast loss of concrete slump over time, effectively improving the situation that the fresh performance does not meet the requirements during the application of seawater and off-shore materials.

[0003] At present, in the actual production and processing process of the retarder, in order to ensure uniform mixing of the materials and improve the production quality, a stirring mechanism is used to stir the raw materials. The retarder that has been fully stirred and mixed is generally discharged through the bottom material port. However, the current retarder stirring and mixing equipment needs to manually open the material port when discharging. For example, a concrete retarder production stirring machine disclosed in Publication No. CN219333876U includes a stirring box (1), which is characterized in that a pretreatment box (2) is connected to the top of the stirring box (1), a sorting assembly (8) is fixedly installed through the left side of the inner cavity of the pretreatment box (2), a crushing assembly (7) is fixedly installed through the right side of the inner cavity of the pretreatment box (2), a protective sleeve (6) is welded at the center of the inner cavity of the pretreatment box (2), a stirring assembly (5) is arranged through the inner cavity of the stirring box (1), and a discharge valve (3) is connected to the bottom of the inner cavity of the stirring box (1). The above-mentioned concrete retarder production stirring machine relies on the discharge mode of the weight of the retarder itself. At the same time, the discharge speed cannot be controlled, and the material port cannot be automatically controlled to close. For example, a concrete retarder mixing equipment disclosed in Publication No. CN220940468U includes a mixing cylinder, a support is fixedly installed outside the mixing cylinder, a servo motor is installed on the support, a rotating shaft is fixedly connected to the output end of the servo motor, and a cleaning structure is arranged outside the rotating shaft. The concrete retarder mixing equipment sets a sliding extension rod on the stirring rod of the original retarder mixing equipment, sets a scraper on the end of the extension rod, and enables the extension rod to conveniently drive the scraper to extend and adhere to the inner wall of the mixing cylinder. Therefore, the present application proposes a retarder stirring and mixing equipment that can automatically control discharge and automatically close. SUMMARY
