The conversion structure 4 includes a motor 41, a rotating shaft 42, a bearing 43 and a rotating plate 44. The output end of the motor 41 penetrates the housing 1 and is in transmission connection with one end of the rotating shaft 42, and the other end of the rotating shaft 42 is rotatably connected to the inner wall of the housing 1 through the bearing 43. The middle of the rotating shaft 42 is rotatably connected to the rotating plate 44. The motor 41 is installed on the housing 1. The dust collection structure 5 includes a fan 51, an exhaust pipe 52, a dust suction hood 53 and an air outlet pipe 54. The right end of the fan 51 is connected to the exhaust pipe 52, the right end of the exhaust pipe 52 is installed with a dust suction hood 53, the left end of the fan 51 is connected to the air outlet pipe 54. The fan 51 is installed on the housing 1. The structures of the first screening structure 6 and the second screening structure 7 are the same and are symmetrically distributed, which is beneficial to screening and standby, and avoids affecting production when blocked or damaged. The rotating plate 44 is arranged under the feed pipe 2, which is convenient for guiding the tar residue through the rotating plate 44. The left end of the air outlet pipe 54 is connected to an external dust cleaner, which is beneficial to centralized treatment of tar residue dust.

[0023] Please refer to Figure 5, the present utility model provides a tar residue screening device. The first screening structure 6 includes a first filter layer 61, a second filter layer 62, a guide plate 63, a first discharge port 64, a second discharge port 65 and a third discharge port 66. The second filter layer 62 is arranged below the first filter layer 61, and the guide plate 63 is arranged below the second filter layer 62. The first discharge port 64, the second discharge port 65 and the third discharge port 66 are respectively installed on the left sides of the first filter layer 61, the second filter layer 62 and the guide plate 63. The first filter layer 61, the second filter layer 62 and the guide plate 63 are all installed on the inner wall of the housing 1, and the first filter layer 61, the second filter layer 62 and the guide plate 63 are all inclined, which is convenient for the tar residue to automatically roll down and be discharged outside by the inclined shape.

[0024] The working principle is as follows:

[0025] First, first place the device at the required position and connect the circuit.

[0026] Second, operate by controlling the fan 51, add the tar residue to be screened into the feeding pipe 2. The dust falling from the feeding pipe 2 is sucked into the exhaust pipe 52 through the dust suction hood 53 and transported to the external dust processor through the air outlet pipe 54 for centralized treatment. The tar residue falling on the upper end of the rotating plate 44, due to the inclined shape of the rotating plate 44, makes the tar residue fall from the left side to the upper side of the first filter layer 61.

[0027] Third, the tar residue is roughly screened by the first filter layer 61, and the large-particle tar residue is filtered on the upper side. The rest falls to the upper side of the second filter layer 62. The second filter layer 62 performs medium screening, and the small-particle tar residue is screened to the lower side of the guide plate. The rest remains on the upper side of the second filter layer 62. Since the dust is extracted to the outside by the fan 51, the tar residue on the upper side of the guide plate 63 achieves the effect of fine screening. Since the first filter layer 61, the second filter layer 62 and the guide plate 63 are all inclined, the screened tar residue is respectively discharged to the outside through the first discharge port 64, the second discharge port 65 and the third discharge port 66, achieving the purpose of screening.

[0028] Fourth, when the screening is blocked or damaged, control the motor 41 to rotate. The output end of the motor 41 drives the rotating shaft 42 to rotate, and the rotating shaft 42 drives the rotating plate 44 to rotate by 90 degrees, so that the direction of guiding the tar residue by the rotating plate 44 is changed. Since the structures of the first screening structure 6 and the second screening structure 7 are the same, one can be used as a standby, avoiding the interruption of production due to blockage or damage, and thus affecting the screening efficiency.

[0029] The control mode of the present utility model is controlled by manually starting and closing the switch. The wiring diagram of the power element and the power supply are common knowledge in the art, and the present utility model is mainly used to protect mechanical devices.
