[0028] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a sand casting dust removal device, comprising: a tank body 1, a motor 2 is fixedly installed on the top of the tank body 1, the output shaft of the motor 2 is fixedly connected to a rotating shaft 3, a conveying disc 4 is fixedly provided on the outer wall of the rotating shaft 3, a discharge port 5 is fixedly provided on the end of the conveying disc 4 away from the bottom of the inner cavity of the tank body 1, a feed port 6 is fixedly provided on the top of the tank body 1, a vibrator 7 is fixedly installed on the outer wall of the tank body 1, a discharge tray 8 is fixedly connected to the inner wall of the tank body 1, an air inlet pipe 9 is penetrated through the top of the tank body 1, an air outlet pipe 10 is penetrated through the side wall of the tank body 1, and a discharge pipe 12 is penetrated through the bottom of the outer wall of the tank body 1.

[0029] like Figure 2 and Figure 3 As shown, the top of the conveying tray 4 is provided with convex points for increasing friction, and the friction between the molding sand and the conveying tray 4 is increased by the convex points, so that the molding sand can be lifted upward along with the conveying tray 4.

[0030] like Figure 2 and Figure 3As shown, the opening end of the discharge port 5 is located between the outer diameter of the conveying tray 4 and the inner diameter of the discharge tray 8. The molding sand lifted up by the conveying tray 4 is discharged to the bottom of the inner cavity of the tank body 1 through the discharge port 5. The position of the discharge port 5 prevents the molding sand from falling onto the conveying tray 4 and the discharge tray 8.

[0031] like Figure 1 and Figure 2 As shown, a dustproof net 11 is fixedly provided at one end of the air outlet pipe 10 located in the inner cavity of the tank body 1. The dustproof net 11 can protect the air outlet pipe 10 to prevent particles from entering the air outlet pipe 10 along with the air.

[0032] like Figure 1 and Figure 2 As shown, an observation window 13 is provided on the outer wall of the tank body 1 , through which the working conditions inside the tank body 1 can be observed.

[0033] like Figure 1 and Figure 2 As shown, a sealing cover is provided at the top of the feed port 6, and the feed port 6 is located directly above the front end of the discharge tray 8. The sealing cover can prevent the molding sand from flying out through the feed port 6 during dust removal to cause environmental pollution, and the molding sand can be placed on the discharge tray 8 through the feed port 6.

[0034] The technical solution provided by the utility model is to pour the molding sand into the discharge tray 8 through the feed port 6. Under the action of the vibrator 7, the molding sand in the discharge tray 8 will quickly fall to the bottom of the tank body 1. In the process of the molding sand sliding on the discharge tray 8, a part of the dust can be removed. The molding sand that falls to the bottom of the tank body 1 will drive the conveyor tray 4 to rotate under the rotation of the motor 2, thereby lifting the molding sand at the bottom of the tank body 1. When it is lifted to the highest point, it will fall again through the discharge port 5, so that it can be cleaned again. The cleaned molding sand is discharged out of the tank body 1 through the discharge pipe 12.

[0035] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.
