[0002] Graphite insulating sand is a functional raw material with graphite as the main component and mixed with insulating aggregates (such as perlite and cenospheres). It is mainly used for insulation in high-temperature scenarios (such as metallurgical furnace linings and photovoltaic silicon material smelting furnace insulation layers). Its use requires extremely high "material uniformity, looseness, and stability".

[0003] Graphite insulating sand contains graphite powder and insulating aggregate, and some production processes add a small amount of binder to improve its formability. When stored for a long time, it is prone to clumping, which affects the performance of the insulating sand. Therefore, a graphite insulating sand turning crane with lifting function is needed.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1 See Figure 1-4A graphite insulation sand turning trolley with lifting function includes a main component 1, which includes: a trolley 11 with a movable block 12 movably connected thereto; a connecting frame 13 fixedly connected to the bottom of the movable block 12; a turning component 2 disposed on the connecting frame 13, the turning component 2 including: a support plate 21 disposed on the connecting frame 13; a lifting mechanism 22 disposed on the connecting frame 13 and the support plate 21; a hopper 23 fixedly connected to the outer end of the support plate 21; a rotating shaft 24 rotatably connected to the inner wall of the hopper 23; and a motor 241 disposed on the outer wall of the hopper 23. The output shaft of the second motor 241 is fixedly connected to one end of the rotating shaft 24; the flip rod 25 is symmetrically and fixedly connected to the outer wall of the rotating shaft 24; the material plate 251 is symmetrically and fixedly connected to the outer wall of the rotating shaft 24; the guide frame 261 is symmetrically and fixedly connected to the right side wall of the hopper 23; the slider 26 is symmetrically and slidably connected inside the guide frame 261; the baffle 27 is fixedly connected to the opposing surface of the slider 26 and slidably connected to the outer wall of the hopper 23; the electric push rod 271 is disposed on the outer wall of the hopper 23, and the top output shaft of the electric push rod 271 is fixedly connected to the slider 26 on one side. The lifting mechanism 22 includes: a cavity 221, formed on the outer wall of the connecting frame 13; a lead screw 222, rotatably connected to the inner wall of the cavity 221, the lead screw 222 passing through the support plate 21, the support plate 21 being threadedly connected to the outside of the lead screw 222, and the support plate 21 being slidably connected to the inner wall of the cavity 221; a bracket 223, fixedly connected to the bottom of the connecting frame 13; and a motor 224, disposed on the top of the bracket 223, the output shaft of the motor 224 being fixedly connected to the bottom end of the lead screw 222. A material level switch 3 is provided on the inner wall of the hopper 23, and a low material level switch 31 is also provided on the inner wall of the hopper 23. The material level switch 3 and the low material level switch 31 are electrically connected to the movable block 12 and the motor 224 via an external controller.

[0015] In use, the overhead crane 11 includes a main beam installed on the top of the factory building or in the silo area to support the weight of other components. End beams are installed at both ends of the main beam, and "wheels" are mounted at the bottom, serving as "support legs" for the crane to move along the track. It also includes a track that provides a fixed path for the crane. The crane's driving mechanism consists of a driving motor, a reducer, and the wheels. An external controller powers the driving motor, and the high-speed rotational power output by the motor is reduced by the reducer and converted into low-speed, high-torque rotation of the wheels. The wheels mesh with the fixed track, driving the movable block 12 to move along the track. The goal is simply to achieve the effect of the movable block 12 moving at the bottom of the overhead crane 11; the specific structure will not be described in detail here.

[0016] Movable block 12 moves hopper 23 to the outlet below the insulation sand silo, controls the opening of the valve at the silo, and the insulation sand is fed into hopper 23. The capacitive level switch 3 forms a "capacitive circuit" with the wall of hopper 23 through the probe. When the material accumulates from above to the contact probe, the dielectric constant of the material will change the capacitance value. The switch detects that the capacitance change exceeds the preset threshold, that is, it outputs a "full signal". At this time, the controller closes the valve at the bottom of the insulation sand silo, and then controls movable block 12 to move hopper 23 out of the bottom of the silo. Then, the lifting mechanism 22 moves hopper 23 upward. The controller controls motor 224 to start. Motor 224 drives screw 222 to rotate. The support plate 21 connected to the external thread of screw 222 moves upward. When motor 224 rotates in the opposite direction, the screw 222 rotates in the opposite direction and drives the support plate 21 to move downward. When the hopper 23 moves above the silo, the electric push rod 271 is extended, which drives the baffle 27 to move upward. The motor 241 drives the tilting rod 25 and the material plate 251 to rotate through the rotating shaft 24. The material plate 251 conveys the insulating sand in the hopper 23 towards the discharge port. The tilting rod 25 agitates and breaks up the locally clumped and sticky insulating sand, and then puts the broken insulating sand back into the silo. This achieves the effect of taking out the insulating sand in batches, processing it, and putting it back into the silo. The breaking effect is good.

[0017] The low level switch 31 installed inside the hopper 23 near the side discharge port is used to detect whether there is any residual insulation sand. When discharging, the material gradually decreases from the side. When the material level is lower than the probe of the low level switch 31, the switch changes from "material present trigger state" to "no material present trigger state" and outputs "discharge completed signal". At this time, the controller controls the motor 241 and the electric push rod 271 to shut down together to avoid idling.

[0018] Example 2 An auxiliary function has been added based on Embodiment 1.

[0019] See Figure 1-4 The cavity 221 and the support plate 21 are both provided with telescopic shells 4 facing each other. The motor 241 is covered with a protective frame 5.

[0020] When the support plate 21 moves upward, the telescopic shell 4 at the top of the support plate 21 retracts, and the telescopic shell 4 fixed at the bottom extends. When the support plate 21 moves downward, the telescopic shell 4 fixed at the top of the support plate 21 extends, and the telescopic shell 4 fixed at the bottom retracts. The telescopic shell 4 blocks the cavity 221, preventing foreign objects from entering the cavity 221 and affecting the normal movement of the lead screw 222 and the support plate 21. The protective frame 5 outside the motor 241 protects the motor 241 and reduces the impact of foreign objects on the motor 241.
