A kind of sand mixer with cleaning mechanism

Abstract

A sand mixer with a material cleaning mechanism. The invention relates to the technical field of sand mixers; , the upper side inside the box is equipped with a cleaning mechanism, the No. 2 motor in the cleaning mechanism is fixed on the upper side wall of the box, and the lower side of the cleaning mechanism is equipped with a mixing mechanism, and the cylinder in the mixing mechanism fixes the box On the left side of the lower surface, a discharge pipe is inserted on the lower end of the right wall of the box body, a check valve is arranged on the middle end of the discharge pipe, and a water pump is arranged on the upper side of the check valve, and the water pump is fixed on the box. The upper end of the right side wall of the body, the water outlet of the water pump is connected to the inside of the box through a pipe, and a cleaning mechanism is installed on the upper side inside the sand mixer, and the inner wall of the box is cleaned through the cleaning mechanism. The molding sand on the side wall is scraped into the box body to prevent the molding sand from standing on the inner side wall of the box body, thereby reducing the waste of resources. The invention has the advantages of reasonable setting and low manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of sand mixers, in particular to a sand mixer with a cleaning mechanism. Background technique [0002] As a device for mixing molding sand, sand mixer is widely used in the foundry industry. During the sand mixing process of traditional sand mixers, molding sand often sticks to the inside of the sand mixer shell, resulting in sand mixing. If it is uneven, it cannot ensure that the molding sand mixing reaches the required standard, which affects the quality of the molding sand and cannot meet the needs of foundry production. At the same time, the binder will also bond the molding sand to the inner wall of the sand mixer shell. When sanding, it may not be possible to remove the mixed molding sand completely, and it will stick to the sand mixer shell for a long time. After the molding sand is hardened, it will become very troublesome to clear it from the sand mixer shell. When mixing sand, hard particles will ...

[0002] As a device for mixing molding sand, sand mixer is widely used in the foundry industry. During the sand mixing process of traditional sand mixers, molding sand often sticks to the inside of the sand mixer shell, resulting in sand mixing. If it is not uniform, it cannot ensure that the molding sand mixing reaches the required standard, which affects the quality of the molding sand and cannot meet the needs of foundry production. At the same time, the binder will also bond the molding sand to the inner wall of the sand mixer shell. When sanding, it may not be possible to remove the mixed molding sand completely, and it will stick to the shell of the sand mixer for a long time. After the molding sand hardens, it will become very troublesome to clear it from the shell of the sand mixer. When mixing sand, hard particles will be produced in the molding sand, which cannot meet the requirements of use, resulting in a waste of molding sand resources. At the same time, some operators prevent the molding sand from sticking to the sand mixer shell by beating the sand mixer shell. This is easy to cause damage to the sand mixer and affect the service life of the sand mixer, which needs to be improved urgently
