Continuous sand mixer is widely used in the foundry industry to mix foundry sand and various additives. However, during use, the sand quality at the head and tail of the sand mixer is often uneven, which is the so-called "head and tail sand" problem, which will affect the quality of castings.

[0003] In order to solve this problem, a device for reducing the head and tailings of a continuous sand mixer is designed to reduce the amount of head and tailings of a continuous sand mixer. Utility Model Content

[0010] When using a device for reducing the head and tail sand of a continuous sand mixer in the technical solution, raw materials are added to the first feed trough through the feed trough, and the raw materials entering the first feed trough are transported through the first feeding mechanism, so that the raw materials enter the stirring tank for stirring. During the stirring process, the raw materials enter the second feed trough, and under the action of the second feeding mechanism, the raw materials continuously fill the second feed trough and surge upward. At this time, the surging raw materials enter the return trough and return to the stirring tank through the third feeding mechanism for further stirring and mixing. After the equipment has been running for a period of time, the third feeding mechanism is stopped, so that the raw materials can overflow through the discharge trough after entering the second feed trough.

At the same time, one end of the return trough away from the stirring trough is connected and installed with the top of the second feeding trough, and the discharging trough is connected and installed on the top of the second feeding trough. When performing specific operations, raw materials are added into the first feeding trough through the feeding trough, and the raw materials entering the first feeding trough are conveyed through the first feeding mechanism, so that the raw materials enter the stirring trough for stirring. During the stirring process, the raw materials enter the second feeding trough, and under the action of the second feeding mechanism, the raw materials continuously fill the second feeding trough and surge upward. At this time, the surging raw materials enter the return trough, and return to the stirring trough through the third feeding mechanism for stirring and mixing again. After the equipment has been running for a period of time, the operation of the third feeding mechanism is stopped, so that the raw materials can overflow through the discharging trough after entering the second feeding trough, thereby achieving the effect of reducing the amount of sand at the head and tail of the sand mixer.
