Technical Field

The utility model relates to the technical field of casting cleaning, in particular to a device for cleaning and recovering casting sand on the surface of a casting.

Background Art

The basic raw materials of sand casting are casting sand and sand binder. The molding sand and core sand are used as modeling materials to make a mold, and liquid metal fills the mold under gravity to produce castings. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting, because the modeling materials used in sand casting are cheap and easy to obtain.

For example, a casting cleaning device disclosed in Chinese patent CN207255219U cleans the surface of the casting by installing a motor and a high-pressure water pump on a bottom plate.

During cleaning, the casting sand on the surface of the casting is not cleaned thoroughly and a lot of casting sand will remain. At the same time, the cleaning casting sand cannot be recovered and pollutes the working environment.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-3. The utility model provides a technical solution: a casting surface casting sand cleaning and recovery device includes a chassis 1, a mounting plate 5 is rotatably provided on the top of the inner cavity of the chassis 1, an annular slide rail 4 for driving the mounting plate 5 to rotate is provided on the top of the inner wall of the chassis 1, a liftable horizontal brush roller 9 is provided below the mounting plate 5 along one radial direction, an electric slide rail is provided at the bottom of the mounting plate 5 along another radial direction, and a vertical brush roller 10 is provided on the sliding part of the electric slide rail.

The horizontal brush roller 9 moves in a complete loop, covering the top of the casting, and the vertical brush roller 10 moves transversely to cover the side of the casting.

The electric slide rail can change the position of the vertical brush roller 10 according to the size of the casting, and brush the sides of castings of different sizes. The inner end of the horizontal brush roller 9 exceeds the center of the circle, and covers the complete plane when rotating, without forming a blank in the middle.

A group of roller conveyors 7 are arranged on both sides of the bottom of the inner cavity of the chassis 1. The casting enters from one side of the chassis 1 and passes through the other side through the transmission of the two groups of roller conveyors 7. A bottom surface cleaning component is arranged between the two roller conveyors 7.

There are feed inlets and discharge outlets on both sides of the chassis 1. When the roller conveyor frame 7 conveys the casting to half of the inner cavity of the chassis 1, the horizontal brush roller 9 brushes the casting. At this time, the roller conveyor frame 7 stops conveying, and the vertical brush roller 10 brushes the side of the casting. After the horizontal brush roller 9 and the vertical brush roller 10 finish brushing the casting, the roller conveyor frame 7 conveys the casting to the discharge outlet, and the roller conveyor frame 7 reciprocates and intermittently conveys the casting that needs to be cleaned in turn.

The chassis 1 is suitable for cleaning castings with regular surfaces and no cavities.

A sliding block is provided on the annular slide rail 4 , and the sliding block is fixedly connected to one end of a diameter of the top of the mounting plate 5 .

The inner cavity of the chassis 1 is provided with a spray head 2 which is located on the outer circle of the mounting plate 5 and tilted downward.

The nozzle 2 is in the shape of a shower head, and the water flow is dispersed into multiple groups so as to evenly cover the surface of the casting, thereby better cleaning the surface of the casting and achieving a better cleaning effect.

The bottom surface auxiliary cleaning assembly includes two rotatable brush rollers and a nozzle. The nozzle is arranged between the two brush rollers. The length direction of the brush roller is perpendicular to the transmission direction of the roller conveyor frame 7.

When the casting moves to the lower end of the brush roller, the bristles on the front brush roller clean the bottom surface of the casting. After the front brush roller finishes cleaning the bottom surface of the casting, the casting moves backward and the nozzle sprays water to rinse the bottom surface of the casting. When the casting moves to the top of the rear brush roller, the brush roller rinses the bottom surface of the casting after rinsing.

When the two brush rollers clean the bottom surface of the casting, the nozzles spray water, which can more perfectly clean the dust and impurities on the bottom surface of the casting and improve the cleaning efficiency.

The bottom of the inner cavity of the chassis 1 is a grid plate, and a collection box 8 is arranged at the bottom of the chassis 1.

The mesh plate is made of metal, which allows dust and impurities falling from the surface of the casting to fall into the collection box 8 at the bottom through the filter screen. The outside of the collection box 8 is connected to a discharge pipe to discharge the casting sand in the collection box 8 so as not to pollute the working environment.

Telescopic rods 6 are provided at both ends of a radius at the bottom of the mounting plate 5, and mounting seats are provided at the bottoms of the two telescopic rods 6, and the horizontal brush roller 9 is rotatably connected between the two mounting seats.

When the telescopic rod 6 is extended downward, the horizontal brush roller 9 can fully contact the casting surface to brush the casting surface. After brushing, the telescopic rod 6 drives the horizontal brush roller 9 to retract, saving space in the chassis 1.

A mounting frame is provided at the bottom end of the sliding part of the electric slide rail, and a driving motor 3 is provided in the inner cavity of the mounting frame. A connecting disk 11 is fixedly connected to the bottom of the driving motor 3, and the output shaft of the driving motor 3 passes through the bottom of the connecting disk 11. The vertical brush roller 10 is detachably arranged at the bottom of the connecting disk 11.

The sliding part of the electric slide rail can move the mounting frame and the vertical brush roller 10 at the bottom of the mounting frame to clean castings of different specifications. When sliding to the outside of the electric slide rail, the vertical brush roller 10 cleans the side of the casting. The vertical brush roller 10 can be removed manually. If it is damaged or aged during the engineering process, the vertical brush roller 10 can be removed in time to facilitate better cleaning.

During operation, when the casting is conveyed to the feed port on the front side of the chassis through the roller conveyor frame 7 and enters the inner cavity of the chassis, the horizontal brush roller 9 rotates in a circle to cover the entire top of the casting for brushing, the electric slide rail drives the vertical brush roller 10 to brush the sides of the casting, and the bottom cleaning component cleans the bottom of the casting. During cleaning, the nozzles 2 arranged on both sides of the chassis spray water on the casting, and the water flow covers the surface of the casting to improve the cleaning process. After cleaning, the roller conveyor frame 7 conveys the casting to the discharge port to leave the chassis to complete the cleaning of the casting.
