Description

Feeding equipment and feeding method for lead extruder

Technical Field

The invention relates to the technical field of cable preparation, in particular to a feeding device and a feeding method for a lead extruder.

Background

The lead extruder is mainly used for wire and cable cladding lead sheath and cable vulcanization production, and is a device for curing and forming a lead sheath on the surface of a cable by extruding and cooling lead liquid in a series to obtain a continuous lead sheath sheathed armoured cable with a large length. The first process of using the lead extruder is to melt lead raw materials (such as lead ingots, alloy lead, lead particles and the like) into liquid through a lead dissolving furnace. It is known that lead has a density greater than that of common metals such as iron and copper, and the same volume of lead has a mass much greater than that of iron, and the feed opening of a lead melting furnace is often located at a distance from the ground where the raw materials are located, so that the feeding of the lead raw materials into the lead melting furnace on a lead extruder also becomes a first difficulty faced by the lead extrusion process. Meanwhile, a part of lead extruding machines of external heating type melting furnaces, such as YQL series lead extruding machines, need to throw in small lead ingots or lead grains to ensure contact with a furnace bottom heating device before the empty furnace of the lead melting furnace is started, so that the damage of the heating device is avoided, and common lead ingots or alloy lead can be normally thrown in after the lead ingot sections or the lead grains are melted.

In the existing production construction, a worker often sends lead raw materials into a lead melting furnace of a lead extruder manually, which is time-consuming and labor-consuming. Meanwhile, since lead is heavy metal and has high toxicity, the long-time contact of workers is unfavorable for the health of workers, so that lead feeding equipment is needed to replace manual feeding. In the prior art, there are three general types of metal lifting devices: the first method is to use a conveyor belt for transmission, but the shapes of different lead raw materials to be transmitted are not uniform due to the large mass of lead, so that the included angle between the conveyor belt and the horizontal plane can be controlled in a certain range, the manufacturing cost is high, and the use environment is limited; the second is to use a vertically arranged conveyor belt and arrange a lifting baffle, the metal block is lifted by the lifting baffle, the metal with a certain shape can only be lifted conventionally, and the lead raw material with higher quality is easy to fall off the conveyor belt at the highest point; the third is to transport metals using the principle of magnetic attraction, but conventional lead raw materials have no magnetism, such a method cannot be used, and such an apparatus is complicated in structure and excessively high in cost. Therefore, a feeding device and a feeding method for a lead extruder, which have simple structures and easy feeding and can well replace manual feeding, are needed at present.

When the chain 32 is adjusted to be too inclined, in order to ensure that the lifting bucket 33 does not leak during operation, the lifting bucket 33 is preferably constructed as shown in fig. 8, bucket frames 366 matching the profile of the lifting bucket 33 are arranged on both sides of the lifting bucket 33, the bucket frames 366 are hinged on the chain 32 and are provided with rollers 363 corresponding to the sliding rails 36, the shovel end 331 of the lifting bucket 33 is hinged with the bucket frames 366, and the feeding end 332 extends out of the pulleys and is slidingly arranged on the adjusting rail 365 on the bucket frames 366. By adjusting the position of the feeding end 332 on the adjusting slide rail 36, the lifting bucket 33 can incline relative to the lifting frame, so that the inclination of the chain 32 is counteracted, and the raw materials in the lifting device 3 are ensured not to fall down.

A motor connected with a rotary baffle plate 42 is arranged outside the shell of the discharging bin 41, the rotation speed of the motor is matched with the rotation speed of the first rotating shaft 34, and the rotation direction is opposite. The material poured from the lifting bucket 33 enters the discharging bin 41 and is blocked by one of the rotating baffles 42, so that buffering is realized, and then the material is pushed into the lead melting furnace 1 by the subsequent rotating baffle 42.

Further, baffles 22 are arranged on two sides of the lead material conveying device 2, and the lead material conveying device 2 is provided with an arc groove 21 matched with the lifting bucket 33 according to the movement path of the lifting bucket 33.

Example 2

The above-described embodiment 1 is generally applicable to a case where the furnace mouth of the lead melting furnace 1 is opened laterally, and the following is preferable for a case where the furnace mouth of the lead melting furnace 1 is provided at the top.

Specifically, after the loading raw material passes through the first sprocket 341, the lifting bucket 33 is limited by the shovel end sliding rail 361, and steadily moves towards the furnace mouth of the lead melting machine, when the lifting bucket 33 bypasses the third sprocket 371, the feeding end sliding rail 362 limits the lifting bucket 33, when the loading raw material of the lifting bucket 33 reaches the position right above the furnace mouth of the lead melting furnace 1, the shovel end 331 of the lifting bucket 33 touches the feeding stop 364, and meanwhile, the lifting bucket 33 is separated from the limit of the sliding rail 36, and as the chain 32 returns, the lifting bucket 33 tilts towards the feeding end 332, preferably, the feeding stop 364 is set to be a roller 363 horizontally connected, so that the lifting bucket 33 keeps a dumping action for a certain time.

After the lifting bucket 33 dumps the raw material and is separated from the feeding block 364, the lifting bucket 33 naturally dumps towards the shovel end 331 because the shovel end 331 is heavier than the feeding end 332, and then the chain 32 bypasses the fourth sprocket 372 without a central shaft, when the lifting bucket 33 reaches the position of the lead grain conveying device, the roller 363 of the feeding end 332 enters the feeding end sliding rail 362 and deflects under the limitation of the feeding end sliding rail 362, and a shovel action is generated.
