Medium-density production line deironing apparatus

Abstract

The invention relates to an iron removing device in a middle density production line, which relates to the technical field of the iron removing device in the middle density production line for removing metals contained in fibers. The iron removing device comprises a paving head, a preformer, a metal alarm and the fibers, wherein the paving head is connected with the fibers, and the fibers pass through the preformer and the metal alarm respectively. The iron removing device is characterized by further comprising an adjusting hand wheel, an adjusting screw rod, and a permanent magnet, wherein the permanent magnet is arranged between the paving head and the performer, the upper end of the permanent magnet is connected with the adjusting screw rod, and the screw rod is provided with the adjusting hand wheel. The iron removing device effectively removes most of metallic impurities before the impurities enter the preformer, reduces the damage caused by the metallic impurities to the preformer, and greatly reduces the production cost increase caused by the metal alarm.

Description

technical field [0001] The invention relates to the technical field of a medium-density production line iron removal device for removing metal contained in fibers. Background technique [0002] In the original medium density production line, the iron remover was installed in the slice conveying device, but it is still inevitable that some metal impurities flow into the subsequent process. At the same time, due to the long-term operation of the subsequent equipment, it is inevitable that some equipment will be damaged due to wear, aging, A certain amount of metal impurities are produced due to faults and other reasons, and enter the subsequent process together with the fibers. The production process of MDF must go through pre-pressing and hot-pressing processes. Pressure belts, air-permeable belts, and hot-press steel belts cause varying degrees of damage, and the price of such accessories is very expensive (ranging from 10,000 yuan to 800 million yuan). Therefore, in the ori...

[0002] In the original medium density production line, the iron remover was installed in the slice conveying device, but it is still inevitable that some metal impurities flow into the subsequent process. At the same time, due to the long-term operation of the subsequent equipment, it is inevitable that some equipment will be damaged due to wear, aging, A certain amount of metal impurities are produced due to faults and other reasons, and enter the subsequent process together with the fibers. The production process of MDF must go through pre-pressing and hot-pressing processes. Pressure belts, air-permeable belts, and hot-press steel belts cause varying degrees of damage, and the price of such accessories is very expensive (ranging from 10,000 yuan to 800 million yuan). Therefore, in the original production line, there is a set of Metal alarm device 6, when metal passes through, the alarm will alarm and stop the production line automatically, and discharge the metal material out of the system, which prevents the metal material from entering the hot press to a certain extent, but on the one hand there may still be a very small amount Metal enters the press, and at the same time, each metal alarm will generate a large consumption, which increases the production cost
