[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] like Figure 1-Figure 6 As shown together, a waste sand and steel shot separation system comprises: a lump iron separation device 1, a conveying device 2 and a sand and shot separation device 3;

[0029] The lump iron separation device 1 comprises a lump iron screening support 11, a lump iron screening device and a lump iron recovery box 14. The lump iron screening device is installed on the lump iron screening support 11. The lump iron recovery box 14 is located below the lump iron discharge port 132 of the lump iron screening device. The feeding end of the conveying device 2 is located below the sand and pellet discharge port 133 of the lump iron screening device.

[0030] The sand and shot separation equipment 3 includes a sand and shot screening bracket 31, a sand and shot screening device, a waste sand recovery box 33 and a steel shot recovery box 34. The sand and shot screening device is installed on the sand and shot screening bracket 31. The waste sand recovery box 33 is located below the waste sand discharge port 322 of the sand and shot screening device. The steel shot recovery box 34 is located below the steel shot discharge port 323 of the sand and shot screening device. The discharge end of the conveying equipment 2 is located above the sand and shot waste material feed port 321.

[0031] When separating waste sand and steel shots, the waste is first poured into the waste feed port 131 of the lump iron screening device, and the lump iron screening device screens the waste, and the larger volume of lump iron screened out falls into the lump iron recovery box 14 through the lump iron discharge port 132, and the remaining waste is a mixture of waste sand and steel shots, which falls onto the feeding end of the conveying equipment 2 through the sand shot discharge port 133, and is transported to the sand shot separation equipment 3 by the conveying equipment 2, and enters the sand shot separation equipment 3 through the sand shot waste feed port 321, and the sand shot separation equipment 3 separates the waste sand and steel shots, and the waste sand falls into the waste sand recovery box 33 through the waste sand discharge port 322, and the steel shots fall into the steel shot recovery box 34 through the steel shot discharge port 323.

[0032] The present application integrates the lump iron separation equipment 1, the conveying equipment 2 and the sand and shot separation equipment 3 together to form a waste sand and steel shot separation system. The waste material flows seamlessly from one device to the next device automatically without frequent loading and unloading. Not only does it require fewer staff, but it also saves time, greatly improves the separation efficiency of waste sand and steel shots, and reduces operating costs.

[0033] In this embodiment, the block iron screening device is preferably a linear vibrating screen 13, which is vertically slidably mounted on the block iron screening bracket 11, and the linear vibrating screen 13 is driven by two vibration motors to vibrate vertically. In other embodiments, the block iron screening device is a drum screen or a swing screen.

[0034] like Figure 3 and Figure 4 As shown together, the linear vibrating screen 13 includes an inclined screening plate 134, the screening plate 134 is provided with a plate screening hole 135, the lump iron discharge port 132 is located at the lower end of the screening plate 134, and the sand and shot discharge port 133 is located below the screening plate 134. The waste passes through the waste feed port 131 and falls onto the upper end of the screening plate 134. Under the action of the vibration force, in the process of flowing from the upper end to the lower end of the screening plate 134, the smaller waste sand and steel shots pass through the plate screening hole 135 and move downward, and are finally output to the conveying equipment 2 from the sand and shot discharge port 133, and the larger lump iron moves downward along the screening plate 134 and falls into the lump iron recovery box 14 from the lump iron discharge port 132.

[0035] An elastic buffer seat 15 is provided at intervals on opposite sides of the linear vibrating screen 13, and an elastic buffer is provided between the elastic buffer seat 15 and the linear vibrating screen 13. The elastic buffer is preferably a coil spring 16, a rubber spring or a rubber shock-absorbing pad. The coil spring 16 is used to prevent vibration from being transmitted to the ground and support the entire weight of the linear vibrating screen 13. When installed, the coil spring 16 must be perpendicular to the ground.

[0036] For the convenience of loading, the block iron screening support 11 is provided with an upper hopper 12, and the upper hopper 12 is located at the waste material feed port 131.
