The spiral conveying mechanism 4 is connected through the bottom of the hopper body 1 and is used to output tar slag to the outside. The material level detection component 3 and the spiral conveying mechanism 4 are electrically connected to the PLC controller installed on the hopper body 1.

[0026] Specifically, a set of tar slag drying equipment is arranged above the device, and the material sealing cover 2 is connected to the tar slag drying equipment through a cylinder lifting mechanism, and the lifting operation of the material sealing cover 2 is controlled by changing the telescopic state of the cylinder lifting mechanism; specifically, the material sealing cover 2 is welded to the telescopic rod of the cylinder lifting mechanism or fastened by bolts, and the discharge port of the tar slag drying equipment is connected to the feed port arranged on the top of the material sealing cover 2 through a pipeline, and the tar slag that has completed the drying process is transported to the inner cavity of the hopper body 1 through the pipeline.

[0027] Specifically, the hopper body 1 is provided with a plurality of groups of leg frames 6 at equal intervals along the length direction of the spiral conveying mechanism 4 .

[0028] Specifically, a plurality of steam heating pipes 7 are sleeved on the peripheral side of the outer wall of the hopper body 1, and one side of each group of steam heating pipes 7 is provided with an air inlet 8 for introducing steam and an air outlet 9 for outputting steam.

[0029] Specifically, in winter when the temperature is low, if the tar residue in the hopper body 1 needs to be kept warm or heated, the user can heat the tar residue in the inner cavity of the hopper body 1 by delivering steam to the air inlet 8, and during the heating process, the steam will enter the steam heating pipe 7 from the air inlet 8, and heat the hopper body 1 along the steam heating pipe 7, and finally be discharged from the air outlet 9.

[0030] Specifically, a sealing gasket is provided at the bottom of the material sealing cover 2, and the shape and size of the sealing gasket match the shape and size of the opening at the top of the hopper body 1.

[0031] Specifically, the inner cavity of the hopper body 1 for containing tar residue is V-shaped, and the size of the bottom of the inner cavity matches the size of the screw conveying mechanism 4 to ensure the sealing effect when the material sealing cover 2 is buckled and connected to the hopper body 1.

[0032] Specifically, the spiral conveying mechanism 4 includes a conveying trough 41, a shaftless spiral conveying blade 42 and a driving motor 43. The discharge end of the conveying trough 41 passes through the side wall of the hopper body 1 and extends outward. The other end of the conveying trough 41 is fixedly connected to the inner cavity wall of the hopper body 1, and the size of the conveying trough 41 matches the size of the bottom of the inner cavity of the hopper body 1. The shaftless spiral conveying blade 42 is rotatably connected in the conveying trough 41.

[0036] The use process of the utility model is as follows:

[0037] First, the hopper body 1 is placed under the material sealing cover 2, and the material sealing cover 2 is controlled to descend by the cylinder lifting mechanism until the material sealing cover 2 is buckled and connected to the top of the hopper body 1; at this time, the tar slag drying equipment is connected to the feed port opened on the material sealing cover 2 through a pipeline, and the tar slag that has completed the drying process is transported to the inner cavity of the hopper body 1;

[0038] Secondly, the material level detection component 3 will monitor the amount of tar residue entering the inner cavity of the hopper body 1 in real time. When the amount of tar residue reaches a preset value, the material level detection component 3 will send a signal to the PLC controller. After receiving the signal, the PLC controller will control the tar residue drying equipment to stop discharging tar residue into the hopper body 1, and control the material sealing cover 2 to rise to the initial position through the cylinder lifting mechanism;

[0039] Then, during the process of discharging tar residue from the tar residue drying equipment, the user can collect harmful gases through the waste gas collection port 5 to facilitate the subsequent treatment of the harmful gases; at the same time, steam can be introduced into the air inlet 8 according to actual conditions to achieve the purpose of heating and heat preservation of the tar residue;

[0040] Finally, after the hopper body 1 is moved to the storage and collection area for the tar slag, the power switch for controlling the working state of the drive motor 43 is turned on, and the shaftless spiral conveying blade 42 will start to rotate under the drive of the drive motor 43 and cooperate with the conveying trough 41 to complete the unloading operation of the tar slag.
