Description

Technical Field

[0001] This utility model relates to the field of sand mixers, specifically to a water glass sand mixer. Background Technology

[0002] A water glass sand mixer is a device used for mixing water glass sand, primarily for preparing water glass sand in the foundry industry. Water glass sand is a commonly used molding material, and the choice of sand mixer during its preparation significantly impacts the quality of the sand mold and production efficiency. A Chinese patent (authorization announcement number CN 222113445 U) discloses a water glass sand mixer that achieves thorough mixing of water glass sand and catalyst through the coordination of a servo motor, bevel gears, bevel gears, a rotating rod, a stirring rod, a servo motor, a worm gear, a worm wheel, a rotating rod, and a stirring frame. This results in better mixing and faster production. However, this design cannot effectively scrape away sand adhering to the inner wall of the mixer, leading to insufficient mixing of water glass and sand. Therefore, those skilled in the art have developed a water glass sand mixer to address the problems mentioned in the background section. Utility Model Content

[0004] Preferably, a machine cover is installed on the top of the tank, with a feed inlet on the upper side of the machine cover and a discharge outlet on the lower side of the tank. Multiple support feet are installed on the outer wall of the tank.

[0005] Preferably, the limiting ring is provided with a limiting groove, an anti-detachment plate is installed on the outer wall of the limiting ring, a limiting plate is installed in the limiting groove, the limiting plate is installed on the side wall of the slider, an anti-detachment groove is provided on the inner side of the limiting plate, and an anti-detachment plate is provided in the anti-detachment groove;

[0006] Preferably, the slider is connected to the connecting rod, a connecting ring is installed in the middle of the connecting rod, the outer wall of the connecting ring is provided with multiple slots, a card plate is installed in the slot, and the card plate is installed on the outer wall of the rotating shaft.

[0007] The technical effects and advantages of this utility model are as follows:

[0008] 1. The scraper blades, using trapezoidal scraper heads, scrape away sand adhering to the inner wall of the sand mixer tank, ensuring uniform mixing of water glass and sand. This improves material uniformity and reduces dead zones and adhesion during the mixing process, thereby increasing the efficiency of the sand mixer.

[0009] 2. The connecting rod is fixed by the card plate installed on the outer wall of the rotating shaft, which is inserted into the slot in the connecting ring. The limiting groove in the limiting ring and the anti-detachment plate installed on the outer wall ensure the normal operation of the scraper when the rotating shaft rotates, and prevent it from falling off during rotation. The structure is simple, easy to disassemble and assemble, and facilitates later cleaning and maintenance. Attached Figure Description
