Description

Technical Field

[0001] This application relates to the technical field of hazardous substance treatment devices, and in particular to a hazardous substance treatment device for the extrusion section of plastic cables. Background Technology

[0002] During cable manufacturing, insulating material needs to be applied to the clean surface of the wire core to prevent current leakage. Common insulating materials include polyethylene (PE) and polyvinyl chloride (PVC).

[0003] Typically, an extrusion method is used to extrude and wrap the insulation layer onto the cable conductor. The cable conductor enters the extruder, which wraps the molten insulation layer around it. The cable conductor wrapped with insulation material is then extruded through the extrusion nozzle. During extrusion, the insulation layer is in a molten state. After the cable conductor moves a certain distance, the insulation layer becomes relatively stable. Then, the cable conductor is placed in a cooling water tank to cool and set the insulation layer.

[0004] There are usually no protective measures for the distance from the extruder to the cooling water tank of the cable conductor. However, the molten insulation layer is exposed to the air, which will produce harmful substances such as hydrogen chloride, vinyl chloride, non-methane total hydrocarbons, and polyvinyl chloride dust. These harmful substances will diffuse into the air and easily cause harm to the human body. Summary of the Invention

[0005] In order to improve the problem of harmful substances spreading due to the exposure of the molten insulation layer to air, this application provides a device for treating harmful substances in the extruded portion of plastic cables.

[0006] The technical solution of the device for treating hazardous substances in the extrusion section of plastic cables provided in this application is as follows:

[0007] A device for treating hazardous substances in the extrusion section of plastic cables includes two fixed frames and a collection box installed between the two fixed frames. The two fixed frames are a first fixed frame fixed to an extruder and a second fixed frame fixed to a cooling water tank. The collection box can be snapped into and fixed to the adjacent fixed frames. An air inlet is installed on the top of the collection box, and an air intake fan is installed at the air inlet. A treatment box is arranged below the collection box, and a connecting pipe is installed between the bottom of the collection box and the treatment box. An exhaust fan and an activated carbon filter are installed in the connecting pipe. An absorbent liquid tank is installed below the treatment box, and the absorbent liquid tank stores absorbent liquid for absorbing hazardous substances. An air outlet is provided on the side wall of the absorbent liquid tank. A spray head is installed on the top of the treatment box, and an inlet pipe is installed between the spray head and the absorbent liquid tank. A water pump is installed on the inlet pipe. An outlet channel communicating with the absorbent liquid tank is opened on the bottom surface of the treatment box.

[0008] By adopting the above technical solution, the cable conductor enters the collection box directly through the extrusion port of the extruder. The activated carbon filter in the collection box absorbs some of the harmful substances in the harmful gas. The blower rotates and blows air into the collection box through the air inlet, so that the filtered harmful gas enters the treatment box through the connecting pipe. Then, the water pump is started and the spray head sprays absorbent liquid onto the harmful gas in the treatment box. The absorbent liquid absorbs the harmful substances in the harmful gas. The purified harmful gas enters the air through the air outlet. The absorbent liquid that has absorbed the harmful substances enters the absorbent liquid tank through the liquid outlet channel for recycling. This achieves the collection and treatment of harmful substances and reduces the possibility of harmful substances spreading into the air and causing harm to the human body.

[0009] Preferably, the collection box is provided with a movable frame and a driving component for pushing the movable frame to move along the length direction of the collection box.

The movable frame is provided with a limiting component for driving the two arc-shaped plates to move towards each other.

[0010] By adopting the above technical solution, the cable conductor enters the collection box from the extrusion port. Since the cable conductor needs to move a distance to reach the cooling water tank, the end of the cable conductor away from the extrusion port is prone to bend downward under its own weight during the movement. Two arc-shaped plates are used to limit the end of the cable conductor, so that the cable conductor remains horizontal during the movement. Then, the drive assembly is used to drive the arc-shaped plates to move, so that the arc-shaped plates and the cable conductor move synchronously.

The clamping blocks are threadedly engaged with the bidirectional lead screw. The movable frame is provided with a rotating component for driving the bidirectional lead screw to rotate.

[0012] By adopting the above technical solution, when the end of the cable conductor moves between the two arc plates, the rotating component drives the bidirectional lead screw to rotate, and the bidirectional lead screw drives the two arc plates to move towards each other, so that the inner arc surface of the arc plate fits against the outer circumferential surface of the cable conductor, thereby limiting the end of the cable conductor.

[0013] Preferably, the rotating assembly includes a rotating sleeve rotatably mounted on the movable frame. A driving gear is fixedly fitted on the outer circumferential surface of the rotating sleeve, and a driven gear that meshes with the driving gear is fixedly fitted on the outer circumferential surface of the bidirectional lead screw.

A plurality of spiral protrusions are evenly distributed on the outer circumferential surface of the moving rod, and a plurality of spiral grooves are formed on the inner circumferential surface of the rotating sleeve. The spiral protrusions and the spiral grooves mesh with each other.

[0014] By adopting the above technical solution, the moving rod is inserted into the rotating sleeve. When the moving rod is moved upward, the spiral protrusion and the spiral groove press against each other, thereby pushing the rotating sleeve to rotate.

[0022] By adopting the above technical solution, after the staff observes through the glass window that all the cable conductors have moved from the extruder into the cooling water tank, the moving frame is moved to the end of the collection box near the extruder. Then, the control block is pressed down, so that the moving contact plate two and the fixed contact plate two make electrical contact. The battery two supplies power to the electromagnetic block two. The attraction force of the electromagnetic block two on the magnetic attraction block two is greater than the attraction force of the electromagnetic block one on the magnetic attraction block one, so that the moving block moves down to reset.

[0058] When the arc plate 46 limits the cable conductor and moves to the side of the housing body 11 near the cooling water tank, the inner arc surface of the arc plate 46 remains in contact with the outer circumference of the cable conductor. After the cable conductor has fully entered the cooling water tank, the operator controls the drive motor 53 to rotate, so that the moving frame 4 moves to the side near the extruder, and the moving block 8 is located above the electromagnetic block 9. Then, the control block 91 is pressed down, so that the moving contact 96 and the fixed contact 97 make electrical contact. The battery 98 supplies power to the electromagnetic block 9, and the electromagnetic block 9 attracts the magnetic block 89.

[0059] The implementation principle of a device for treating hazardous substances in the extrusion part of a plastic cable according to an embodiment of this application is as follows: the cable conductor enters the housing body 11 from the extruder, and the end of the cable conductor presses against the abutment block 85, so that the moving contact piece 851 and the fixed contact piece 852 make electrical contact. The electromagnetic block 76 is energized and works, and the electromagnetic block 76 attracts the magnetic block 83. The electromagnetic block 76 drives the moving block 8 to move upward.

[0060] The moving block 8 drives the moving rod 75 to move upward, and the spiral protrusion and the spiral groove mesh with each other, thereby driving the rotating sleeve 72 to rotate. The rotating sleeve 72 drives the driving gear 73 to rotate, the driving gear 73 drives the driven gear 74 to rotate, the driven gear 74 drives the bidirectional lead screw 61 to rotate, and the bidirectional lead screw 61 drives the two arc plates 46 to move towards the direction close to the cable conductor, so that the inner arc surface of the arc plate 46 is in contact with the outer peripheral surface of the cable conductor, thereby limiting the cable conductor.

[0061] Start the drive motor 53, which drives the reciprocating screw 51 to rotate. The reciprocating screw 51 drives the moving frame 4 to move towards the cooling water tank. The arc plate 46 moves synchronously with the cable conductor, so that the cable conductor remains horizontal during the movement, so that the end of the cable conductor can smoothly enter the cooling water tank.
