Description

Technical Field

[0001] This utility model relates to the field of raw material cleaning technology, specifically a raw material cleaning device for metal casting. Background Technology

[0002] Metal casting raw materials mainly include molten materials such as pig iron, scrap steel, and recycled materials, as well as molding materials such as casting sand. Quartz sand is widely used in the casting process, mainly because it has high fineness, good thermal stability and durability. During the processing of quartz sand, the crushed sand needs to be cleaned.

[0003] Chinese Utility Model Announcement No. CN222020230U includes a frame with a cleaning tank on it. A top cover is connected to the top of the cleaning tank. A water inlet pipe is located on one side of the cleaning tank. A rotatable roller along its length is installed inside the cleaning tank. Multiple filter holes are provided on the circumference of the roller. A feed inlet and a discharge outlet are respectively located at both ends of the roller. A feeding hopper is located at the feed inlet. A spiral guide plate is provided on the inner wall of the roller. A belt mounting groove is provided at the connection between the feed inlet and the roller. A servo motor is fixed on the top cover. A pulley is connected to the output end of the servo motor. The pulley is connected to the roller via a belt. A drain valve is located at the bottom of the cleaning tank. A brushing mechanism is located above the roller. This equipment can achieve continuous feeding and cleaning of quartz sand, greatly improving work efficiency.

[0004] The applicant discovered some shortcomings in the use of the patent: the raw materials discharged from the outlet after cleaning contain moisture on their surface. Since it does not have a drying function, the water-containing raw materials are inconvenient for subsequent processing.

[0005] Therefore, this utility model designs a raw material cleaning device for metal casting to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this invention is to provide a raw material cleaning device for metal casting, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a raw material cleaning device for metal casting, comprising: a cleaning tank, a mesh cylinder rotating between the two sides of the cleaning tank, an inlet and an outlet respectively provided on the two sides of the mesh cylinder, a drain outlet on one side of the bottom of the cleaning tank, a collection box installed below the outlet side of the cleaning tank, a U-shaped plate fixedly installed on the inner wall of the collection box, the U-shaped plate penetrating one side of the collection box, a water filter screen provided on the side of the U-shaped plate inside the collection box, a drain outlet at the bottom of the collection box, and long boxes installed on the inner walls of both ends of the collection box, the long boxes being above the water filter screen, and a plurality of nozzles provided at one end of the long boxes.

[0008] Preferably, the collection box is equipped with a vibrator. Activating the vibrator can cause the collection box to vibrate, which in turn causes the U-shaped plate to vibrate, thus preventing raw materials from accumulating on the U-shaped plate.

[0009] Preferably, a main air box is installed on one side of the collection box, a hot air fan is provided at the bottom of the main air box, and air pipes are installed at both ends of the main air box. The two air pipes are respectively connected to two long boxes. When the hot air fan is started, hot air enters the two long boxes simultaneously through the air pipes and the main air box, so that several nozzles at both ends spray hot air.

[0010] Preferably, an L-shaped feeding pipe is installed on one side of the cleaning box near the feed inlet, with the bottom of the L-shaped feeding pipe located inside the feed inlet. The L-shaped feeding pipe facilitates the addition of raw materials by the staff.

[0011] Preferably, both the sewage outlet and the drain outlet are equipped with valves.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, the raw material is discharged through the outlet and enters the U-shaped plate of the collection box. The filter screen blocks the raw material, while the water in the raw material passes through the filter screen, thereby achieving preliminary water removal. Due to the tilt of the U-shaped plate, the raw material will roll downward. During the rolling process, the nozzle sprays hot air to dry the raw material and further remove water, which facilitates the further processing of the cleaned raw material.
