[0002] The sand mixer is an important equipment in the foundry process. Only by fully mixing the no-hardening resin sand can the quality of the mold be guaranteed and castings that meet the requirements can be produced. However, such mixers commonly used in the foundry industry in the past are all Using the ordinary screw conveying method, the mixing effect is not ideal, and the usual productivity is only about 30% to 40%, which cannot meet the current production requirements of large castings, and the efficiency is low

The invention provides a continuous sand mixer which is simple in structure and improves the mixing efficiency and reliability. The continuous sand mixer comprises a spiral conveyor, a conveying pipeline, a transfer stirring device, a conveying belt and an elevator. The spiral conveyor is horizontally arranged in the conveying pipeline. A feeding hopper is arranged on one side of the conveying pipeline, and the other side of the conveying pipeline is provided with a discharging port and a transfer port. The transfer port is connected with the transfer stirring device. The conveying belt is located under the transfer stirring device. The elevator is used for elevating a mixture on the conveying belt into the feeding hopper. The transfer stirring device comprises a distributing hopper, a stirring tank and four stirrers. The top of the stirring tank is provided with an inlet, and the bottom of the stirring tank is provided with an outlet. The stirring tank is provided with four stirring bins. The distributing hopper is used for distributing the mixture in the transfer port into the four stirring bins. The stirrers are arranged in the stirring bins in a one-to-one correspondence mode. In working, the continuous sand mixer improves the mixing reliability and is high in efficiency.
Description
technical field [0001] The present invention relates to a sand mixer, in particular to a continuous sand mixer. Background technique [0002] The sand mixer is an important equipment in the foundry process. Only by fully mixing the no-hardening resin sand can the quality of the mold be guaranteed and castings that meet the requirements can be produced. However, such mixers commonly used in the foundry industry in the past are all The mixing effect is unsatisfactory with the common screw conveying method, and the usual production rate is only about 30% to 40%, which cannot meet the current production requirements of extra-large castings, and the efficiency is low. Contents of the invention [0003] Aiming at the above problems, the present invention provides a continuous sand mixer with simple structure and improved mixing efficiency and reliability. [0004] The technical solution of the present invention is: comprising screw conveyor, conveying pipeline, transfer mixing ...
