Detailed Description

The following description of the embodiments with reference to the drawings is provided to explain the embodiments of the present invention in further detail, such as the shapes and structures of the components, the mutual positions and connection relationships among the components, the functions and working principles of the components, the manufacturing process, and the operation and use method, etc., so as to help those skilled in the art to understand the concept and technical solutions of the present invention more completely, accurately and deeply.

As shown in fig. 1, the foundry waste sand recycling system is provided with a first belt conveyor 1 for transporting waste sand to recycle, the first belt conveyor 1 is generally horizontally arranged, the tail end of the first belt conveyor is arranged above a crushing plate 2, the crushing plate 2 is a flat plate arranged in an inclined manner, the tail end of the first belt conveyor 1 is arranged above the upper part of the crushing plate 2, the crushing plate 2 is fixed on a first vibrator 5, crushing nails are densely distributed on the upper surface of the crushing plate 2, so that the waste sand on the first belt conveyor 1 falls into the crushing plate 2 and is scattered by the crushing nails on the upper part of the crushing plate 2, and then the waste sand is vibrated along with the first vibrator 5 and is downwardly displaced along the inclined crushing plate 2, meanwhile, the waste sand can be continuously impacted on the crushing nails, so that the waste sand is fully cracked and crushed.

In order to further improve the crushing effect, the distance between the tail end of the first belt conveyor 1 and the crushing plate 2 right below the first belt conveyor is 80-150cm, so that waste sand agglomerates can be beaten on the crushing nails by the self gravity to achieve a better initial crushing effect, if the distance is too small, the effect is general, the dust raising is too large when the distance is too large, and the effect of 80-150cm is optimal. Simultaneously the first broken nail group 3 that the first half of crushing plate 2 was vertical setting, a vertical direction schizolysis waste sand when being used for waste sand to fall down, the striking is on the broken nail of first broken nail group 3 about the waste sand when utilizing the shaking force simultaneously, reach the broken effect of striking, broken great waste sand caking, the latter half is the broken nail group 4 of second that sets up to the slope of the first half, promptly every broken nail orientation of the broken nail group 4 of second shakes gliding waste sand down, the broken nail of the broken nail group 4 of second is less than 15 degrees with 2 contained angles of crushing plate, and the broken nail group 4 density of second is greater than first broken nail group 3, the broken nail group 4 of second down density is big more, a waste sand caking for broken fritter, can reach better broken schizolysis effect like this.

The bottom end of the crushing plate 2 is located above the crushing platform 12, the crushing platform 12 is a horizontally arranged platform for containing waste sand falling from the crushing plate 2, one side of the crushing platform 12 is located below the lower end of the crushing plate 2, a push plate 10 with a long plate-shaped structure is arranged along the side, a crushing roller 6 arranged along the side is arranged on the adjacent side of the push plate 10, the crushing roller 6 is a cylindrical rod for crushing the waste sand, the push plate 10 and the crushing roller 6 are perpendicular to each other, when the push plate 10 and the crushing roller 6 are located at the initial position, the interference does not occur, the push plate 10 is connected with a second hydraulic cylinder 11, a second hydraulic cylinder 11 and the push plate 10 can be indirectly connected through a connecting rod mechanism, the connecting rod mechanism is used for the layout and force transmission of equipment components, the crushing roller 6 is fixed on a rotating shaft, the rotating shaft is installed on a support 8, the support 8 is connected with a first hydraulic cylinder 9, the support 8 is also, the first hydraulic cylinder 9 is perpendicular to the stroke direction of the second hydraulic cylinder 11.

In order to enable the grinding roller 6 to adapt to waste sand with different laying thicknesses, rotating shafts at two ends of the grinding roller 6 are fixed on a support 8 through vertically arranged spring rods 7, the spring rods 7 can automatically adjust the distance between the grinding roller 6 and the grinding table 12, namely the laid waste sand is large in thickness, the waste sand can upwards extrude the grinding roller 6, and then the grinding roller 6 can upwards extrude the spring rods 7 to ascend.

Second pneumatic cylinder 11 is fixed on the third pneumatic cylinder 17 of vertical setting, and the position of second pneumatic cylinder 11 can be reciprocated in the vertical direction motion of third pneumatic cylinder 17, then can adjust the interval of eaves and grinding down platform 12 under push pedal 10. The third hydraulic cylinder 17 has three height strokes, the lowest position: eaves contact grinding table 12 under push plate 10, and under this state, push plate 10 can grind table 12, intermediate position with useless sand propelling movement department: eaves and grind the height that platform 12 intervals piled up waste sand for the plan under push pedal 10, under this state, push pedal 10 can carry out laying of waste sand, and the roller 6 of being convenient for smash pulverizes waste sand, highest position: the distance between the lower brim of the push plate 10 and the grinding table 12 is far higher than the height of the planned waste sand stacking, and in this state, the push plate 10 is used for displacement without contacting the waste sand.

A screen 13 is arranged below the grinding table 12 at the tail end of the stroke of the push plate 10, the screen 13 is fixed on a second vibrating machine, the screen 13 is used for vibrating and scattering waste sand agglomerates and recovering scattered waste sand, a recovery hopper 15 is arranged below the screen 13, a second belt conveyor 16 is arranged below the recovery hopper 15, and the second belt conveyor 16 conveys the recovered and processed waste sand to a waste sand stacking position.

Based on the control method of the casting waste sand recovery system, after the system is started, the first belt conveyor 1, the second belt conveyor 16, the first vibrator 5 and the second vibrator 14 work;

the following operations are completed by the cooperation of the three hydraulic cylinders at set time intervals:

the third hydraulic cylinder 17 is lifted to the middle position, the second hydraulic cylinder 11 is extended to 70-85% of the stroke, the push plate 10 carries out waste sand laying, the second hydraulic cylinder 11 is moved to 70-85% of the extension stroke, redundant waste sand which cannot be laid is not directly pushed onto the screen 13 but stacked at the tail end of the grinding table 12, then the third hydraulic cylinder 17 is lifted to the highest position, the second hydraulic cylinder 11 retracts to the initial position, then the third hydraulic cylinder 17 is lowered to the lowest position, the push plate 10 returns to the lowest position, any waste sand cannot be touched, the second hydraulic cylinder 11 is extended to 100% of the stroke and retracts to the initial position, and the grinding roller 6 finishes a grinding step of laying waste sand.

In order to avoid pushing the push plate 10 and the grinding roller 6 to push the waste sand out of the grinding table 12, collecting grooves are arranged on three sides (except one side above the screen 13) of the grinding table 12, the collecting grooves are inclined groove bodies which extend out of the grinding table 12 and are positioned below the upper surface of the grinding table 12, the three sides are inclined and assembled to the same lowest end, and the lowest end is positioned above the screen 13, so that scattering and waste of partial waste sand are avoided.

The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
