[0051] In some embodiments, the calcium carbide pot unloading system based on multi-pot flipping is generally arranged between two calcium carbide cooling workshops, and unloads the calcium carbide pots in the two calcium carbide cooling workshops at the same time, further improving the unloading efficiency of the calcium carbide pots.

[0052] Specifically, at least one first transfer vehicle 8 is running on the first track 7 between the starting end of the loading roller line 2 and the cooling roller line 5, and the number of the first transfer vehicles 8 is set according to the production capacity requirements of the production line; the first transfer vehicle 8 is used to transport the calcium carbide material pot on the sorting roller line 3 to the loading roller line 2 or the cooling roller line 5 in an orderly manner; the first track 7 is arranged along the vertical direction of the motorized roller line in the loading roller line 2 and the cooling roller line 5, and extends to one end of the sorting roller line 3, so that the first transfer vehicle 8 can carry out material transportation between the sorting roller line 3, the loading roller line 2 and the cooling roller line 5.

[0053] Specifically, a temperature measuring device is installed on the first transfer vehicle 8. In some embodiments, a temperature sensor and a temperature monitoring system are used. The temperature of the calcium carbide pot removed from the sorting roller line 3 is detected by the temperature measuring device on the first transfer vehicle 8. The calcium carbide pot that reaches the cooling temperature is directly sent to the loading roller line 2, and the calcium carbide pot that does not reach the cooling temperature is sent to the motorized roller line of the first row of the cooling roller line 5.

[0054] Furthermore, a second track 9 is arranged at one end of the cooling roller conveyor 5 away from the loading roller conveyor 2 in a vertical direction along the motorized roller conveyor, and at least one second transfer vehicle 10 is running on the second track 9. The number of the second transfer vehicles 10 is set according to the production capacity requirements of the production line; it is used to arrange the cooled calcium carbide pots on the first row of motorized roller conveyors of the cooling roller conveyor 5 in sequence starting from the last row. At this time, it can ensure that the cooling time of the calcium carbide pots placed together is similar, and it is convenient for subsequent batch removal, thereby improving the utilization rate of the cooling roller conveyor 5.

[0055] Specifically, a third track 11 is arranged along the vertical direction at the end of the loading roller line 2, and at least two discharge transfer vehicles 12 are running on the third track 11, including at least one full-material transfer vehicle and at least one empty-pot transfer vehicle; the third track 11 is arranged along the vertical direction of the loading roller line 2, and extends to the starting end of the empty-pot roller line 4, to ensure that the empty-pot transfer vehicle can directly dock with the empty-pot roller line 4, thereby transporting the empty pot; the number of workstations of the discharge transfer vehicle 12 is consistent with the crushing workstation of the hammer unloading machine 6, and the calcium carbide pots running in the loading roller line 2 are discharged and wait on the full-material transfer vehicle. After a group is formed, they are sent to the hammer unloading machine 6 for crushing and discharging; at the same time, the empty pots are also transferred in groups to the empty pot roller line 4 by the empty pot transfer vehicle.

[0056] In some embodiments, the number of workstations of the discharge transfer vehicle 12 may also be smaller than the crushing workstations of the hammer unloading machine 6. At this time, according to the production capacity of the production line, some crushing devices of the hammer unloading machine 6 are closed to meet the usage requirements of different working conditions.

[0057] Specifically, the last workstation at the end of the loading roller line 2 that docks with the discharge transfer vehicle 12 is a lifting and rotating mechanism 13. The lifting and rotating mechanism 13 is composed of a cross lift or a telescopic cylinder lift and a turntable. Before the calcium carbide material pot enters the discharge transfer vehicle 12, it is first adjusted to the same direction through the lifting and rotating mechanism 13, and then enters, which is beneficial to the operation of the hammer unloading machine 6.

The feeding conveyor 17 is inclined 15-60 degrees along the conveying direction, which is convenient for the freight system 18 to load materials while reducing the space occupied by the equipment.

[0060] Specifically, Figure 3-6 The freight system 18 is mainly composed of an electric rail car 1801 and a transfer rail car 1802; the bottom of the electric rail car 1801 runs along the transport track line 19 through rail wheels; the transfer rail car 1802 corresponds to the discharge position of the loading conveyor 17, and can drive the electric rail car 1801 to run in the vertical direction of the transport track line 19, so that the electric rail car 1801 can switch between different transport track lines 19 for operation; the transport track line 19 is arranged in two parallel lines, namely the main transport track line and the auxiliary transport track line; the auxiliary transport track line is used to run the electric rail car 1801 for loading; the main transport track line is used to run the electric rail car 1801 to discharge materials, and finally arrive at the calcium carbide terminal processing station or carry the empty electric rail car 1801; when the empty electric rail car 1801 is loaded, it is loaded from the head. During the loading process, the electric rail car 1801 keeps moving and slowly drops materials to the tail to ensure that the electric rail car 1801 is full; the auxiliary transport rail line connects several cooling workshops, and the main transport rail line is arranged in parallel on one side of the auxiliary transport rail line for connecting to the calcium carbide terminal processing station; and at the exit of each cooling workshop, it is connected to the auxiliary transport rail line through the transfer rail car 1802; when the main transport rail line is busy, the full electric rail car 1801 is suspended on the auxiliary transport rail line of the adjacent cooling workshop; the empty electric rail car 1801 is preferentially transferred by the transfer rail car 1802 to the bottom of the loading conveyor 17 for receiving materials; while waiting for one of the cooling workshops to stop discharging materials, the full electric rail car 1801 is transferred by the transfer rail car 1802 to the main transport rail line, and finally transported to the calcium carbide terminal processing station.

[0061] In some embodiments, Figure 7 As shown, the freight system 18 can also be replaced by an electric truck to directly transport the calcium carbide.

[0062] Specifically, Figure 8 and Fig. 9As shown, the calcium carbide crusher 16 includes a plurality of screening rollers 1601 and crushing rollers 1602 arranged in sequence; the plurality of screening rollers 1601 are distributed at the same interval, and the calcium carbide materials smaller than the interval directly pass through the gap to reach the feeding conveyor 17; the calcium carbide materials larger than the interval are struck and crushed by the crushing rollers 1602 at the end of the screening rollers 1601, and those meeting the size requirements pass through the gap to reach the feeding conveyor 17.

[0063] When using, Fig.10 As shown, first, the lifting mechanism 14 lifts the calcium carbide pot from the storage stereoscopic warehouse 15 to the sorting roller conveyor line 3, and then the first transfer vehicle 8 docks and transfers the calcium carbide pot one by one. At the same time, the temperature of the calcium carbide pot is detected during the transportation process. When it is detected that the calcium carbide pot has reached the cooling temperature, it is directly sent to the loading roller conveyor line 2. The calcium carbide pot that has not reached the cooling temperature is sent to the motorized roller conveyor line of the first row of the cooling roller conveyor line 5. The calcium carbide pots that have entered the motorized roller conveyor line of the first row of the cooling roller conveyor line 5 are discharged one by one from the last row through the second transfer vehicle 10. After cooling is completed, they are sent to the loading roller conveyor line 2 through the first transfer vehicle 8; sent to the The calcium carbide pot on the feeding roller line 2 runs forward via the motorized roller and reaches the lifting and rotating mechanism 13. After being adjusted to the same direction, it is sent to the full material transfer vehicle. After a group is gathered, it is sent to the hammer unloading machine 6 for crushing and discharging. The empty pots after crushing and unloading are also transferred in groups to the empty pot roller line 4 by the empty pot transfer vehicle. Finally, the empty pot is hoisted into the cooling workshop by the lifting mechanism 14. Furthermore, the calcium carbide material enters the calcium carbide crusher 16 from the hammer unloading machine 6 for crushing. The calcium carbide material crushed to a suitable size is transmitted to the freight system 18 via the feeding conveyor 17. The crushed calcium carbide material is finally transported to the calcium carbide terminal processing station via the freight system 18.
