As shown in fig. 1, the sand vibrating platform 7 is provided with four symmetrical fixing rods 6, and the four fixing rods 6 are respectively hinged with the upper ends of the four connecting rods A2. The existence of the fixed rod 6 effectively reduces the weight of the sand vibrating platform 7 and reduces the resetting burden of the plate spring 3 on the parallelogram four-bar mechanism formed by the base 1, the connecting rod A2 and the connecting rod B4.
As shown in fig. 3 and 5, four guide rails 12 are installed in the discharge opening A9 of the conical cylinder A8, and four guide blocks 15 on the rolling column 14 slide in the guide grooves 13 on the inner walls of the four guide rails 12 respectively. The cooperation of the guide block 15 and the guide groove 13 plays a guiding role in the running of the rolling column 14.
The vibration assembly 5 of the present invention is of the prior art.
The working flow of the invention is as follows: in the initial state, the four links A2 are in the vertical state, the leaf spring 3 is in the compressed state, and the shutter a21 is in the closed state for the discharge tube 18.
When it is necessary to separate the casting sand attached to the casting, the casting with the casting sand attached thereto is placed on the sand vibrating platform 7.
Simultaneously, two vibration assemblies 5, a motor A41 and a dust suction pump are started to run, a motor B44 is started to run in a forward and backward reciprocating mode, the motor A41 drives the cone bowl 23 to rotate fast relative to the cone drum A and the cone drum B through a gear C40, a gear B39 and a ring sleeve B27, the ring sleeve A26 on the cone bowl 23 drives the cone drum C to rotate relative to the cone drum A and the cone drum B through a gear B35, a gear A36, a gear A34, a ring sleeve C32 and a connecting rod A31, and the rotating direction of the cone drum C is opposite to the rotating direction of the cone bowl 23.
Meanwhile, the two vibration assemblies 5 drive a corresponding group of parallelogram four-bar mechanisms to swing at a high frequency in a reciprocating manner, the two groups of parallelogram four-bar mechanisms drive the vibration sand platform 7 to vibrate synchronously, the vibration sand platform 7 drives castings on the vibration sand platform to vibrate, casting sand attached to the castings breaks away from the castings under the vibration of the vibration sand platform 7, the casting sand separated from the castings falls into the cone A through the meshed vibration sand platform 7, the casting sand entering the cone A reaches the bottom of the cone bowl 23 through a material leakage opening A9 at the bottom of the cone A, and the casting sand reaching the bottom of the cone bowl 23 moves towards the conical inner wall of the cone bowl 23 under the combined action of friction force and centrifugation at the bottom of the cone bowl 23. At the same time, the agglomerate of foundry sand falling to the bottom of the cone bowl 23 is crushed by the reciprocating crushing column 14, and the partial separation of the binder clay from the foundry sand in the agglomerated foundry sand is achieved.
During the movement of the casting sand to the inner wall of the cone bowl 23, the casting sand which is not adhered with the adhesive after being partially separated from the casting during the vibration process in the casting sand and the casting sand which is crushed and separated by the rolling column 14 fall into the cone barrel B through the leakage holes 24 densely distributed on the side wall of the cone bowl 23, and the casting sand falling into the cone barrel B falls into the discharge barrel 18 through the leakage holes B17 and is accumulated on the baffle plate. And the adhesive clay crushed and separated by the crushing column 14 in the casting sand is discharged from the dust suction holes A10 and the dust suction holes B11 at the dust suction holes A10 densely distributed on the outer side wall of the cone drum A in the process of moving towards the side wall of the cone bowl 23 under the centrifugal action, thereby realizing the primary partial purification of the casting sand.
Most of the foundry sand agglomerates reaching the bottom of the cone bowl 23 are crushed by the reciprocating and moving crushing column 14 and the separation of sand from binder is achieved, and a small part of the foundry sand agglomerates reach the inner wall of the rotating cone C through the inner wall of the cone bowl 23 under the centrifugal action when not crushed by the crushing column 14 in time. Because the rotation direction of the cone drum C is opposite to the rotation direction of the cone bowl 23, the casting sand agglomeration moving to the inner wall of the cone drum C under the action of the rotation and centrifugation of the cone bowl 23 is overturned and collided under the action of the reverse rotation of the cone drum C, the movement speed is gradually reduced under the blocking of the annular groove 30 on the cone drum C, the overturned and collided casting sand agglomeration can also separate the adhesive from the casting sand to a certain extent, when the separated casting sand and clay fall back to the inner wall of the cone bowl 23, the casting sand after separation falls into the cone drum B through the leakage holes 24 on the side wall of the cone bowl 23 and enters the discharge cylinder 18 to be accumulated on the baffle plate, and the clay after separation through the overturned and collided is discharged from the dust collection hole A10 and the dust collection hole B11 due to the negative pressure caused by the dust collection pump, so that the purification of the casting sand is further part is realized.
When the purified casting sand accumulated on the baffle plate reaches a certain amount and the moment generated by the casting sand on the baffle plate is larger than the moment generated by the counterweight 22 on the baffle plate, the baffle plate swings around the pendulum shaft 20 and instantly opens the discharge cylinder 18, the casting sand accumulated on the baffle plate is discharged through the opened discharge cylinder 18, and the baffle plate swings back around the pendulum shaft 20 under the action of the counterweight 22 to reset and close the discharge cylinder 18 again.
When the casting sand attached to the casting is completely separated from the casting, the operation of the motor A41 and the motor B44 and the two vibration assemblies 5 is stopped.
In summary, the beneficial effects of the invention are as follows: the invention can effectively separate the castings attached with sand by the sand vibrating platform 7 driven by the vibration assembly 5, integrates sand vibrating, sand crushing, dust removing and purifying, and can effectively separate and purify resin or clay binder and sand in the casting sand after the castings are fully separated from the sand, thereby improving the regeneration purity of the casting sand while achieving casting, reducing the procedures of separating and purifying the casting sand from the castings by integrating the traditional equipment for assisting the separation and purification of the castings sand and the like, and improving the separation efficiency of the castings and the attached sand and the purification, recovery and reutilization efficiency of the sand.
