Novel sand mixer facilitating automatic feeding

Abstract

The invention discloses a novel sand mixer facilitating automatic feeding. The novel sand mixer comprises a liquid charging device and a solid charging device; the liquid charging device comprises a liquid tank, a charging tank and a transmission motor; the solid charging device comprises a solid tank and a bucket elevator; the solid tank is arranged on one side of a sand mixer body through a solid tank support; a material outlet of the solid tank is arranged over a sand inlet of the sand mixer body; a discharging port of the bucket elevator is arranged over a feeding port of the solid tank. By means of the novel sand mixer facilitating automatic feeding, liquid raw materials and solid raw materials can be conveniently added into the sand mixer, and can be subjected to quantitative adding,the matching of the raw materials can be accurate, liquid can also be dispersed uniformly and added into the sand mixer, and molding sand can be mixed more uniformly; and meanwhile, the labor intensity of a worker can also be relieved, and the sand mixing work efficiency is improved.

Description

technical field [0001] The invention relates to a sand mixer, in particular to a new sand mixer which is convenient for automatic feeding. Background technique [0002] The sand mixer is the molding sand mixing equipment often used in the foundry industry. The preparation of the molding sand usually requires adding a variety of raw materials. The commonly used clay sand and water glass sand are both liquid and solid raw materials. Various raw materials are mixed in advance. The pre-calculated ratio is installed and added accurately. Therefore, before adding materials, the operator needs to weigh and measure each group of raw materials, and then add them to the sand mixer. This will undoubtedly increase the labor intensity of the operators and the measurement of raw materials. The accuracy is not enough, and the existing sand mixers generally have metering devices, and at the same time, they cannot automatically add raw materials, and when adding raw materials, usually all gr...

The commonly used clay sand and water glass sand are both liquid and solid raw materials. Various raw materials are mixed in advance. The pre-calculated ratio is installed and added accurately. Therefore, before adding materials, the operator needs to weigh and measure each group of raw materials, and then add them to the sand mixer. This will undoubtedly increase the labor intensity of the operators and the measurement of raw materials. The accuracy is not enough, and the existing sand mixers generally have metering devices, and at the same time, they cannot automatically add raw materials, and when adding raw materials, usually all groups of raw materials are directly added to the sand mixer, especially when adding liquid raw materials , usually poured directly into the sand mixer, which is very unfavorable for the sand mixer to perform sand mixing, and cannot quickly disperse the liquid raw materials. It is often necessary to increase the sand mixing time to mix the molding sand evenly, which also reduces the mixing efficiency. The efficiency of the sand, and will have a certain impact on the quality of the mixed sand
