Abstract

PURPOSE: An apparatus for removing dust attached on papers is provided to produce papers having superior printing quality by removing dust from the surface of papers. CONSTITUTION: Large-sized dust is removed by using a brush(1). An ionizer(2) is provided to neutralize a charge of a paper surface by using ions. At this time, the ionizer(2) sprays pressurized air onto the surface of the paper so that dust attached on the paper are easily separated from the paper surface. The dust separated from the paper surface are introduced into a casing(4) by means of an air knife(3) spraying compressed air. Then, dust introduced into the casing(4) are discharged to the outside through a flexible tube(5) by means of a dust collector.

Description

Dust remover system for the Paper Industry}

In the present invention, paper produced in a large group of companies in the paper-related industry with a large production facility has been a major cause of deterioration in print quality due to the share of the paper and US materials when printing in the printing process, but there is no particular interest and measures. However, with the development of the industry, the demand for improvement of print quality has begun to emerge from the demand source, and the paper industry is also seeking to establish countermeasures.

The purpose of the present invention is to produce paper with high print quality by removing the equity and the fine materials which are the main causes of the deterioration of the print quality, and by the method of printing quality oriented, the equity of the ground and the US material removal device and the equity separated from the ground. It consisted of a processing apparatus.

The detailed functions of this equity eliminator can be classified into eight types, and each component is operated in one piece simultaneously.

The phenomenon that the fine paper powder is adsorbed on the paper surface is generated by heat or static electricity generated during the manufacturing process. Figure 2 is described in detail as a structural diagram of the stake removal device when the paper is adsorbed as the paper passes the upper surface of the stake removal device.

As shown in Fig. 2, the first and second stake removal processes are simultaneously performed. First, sweep a large stake with the primary brush (1). The primary ionizer (2) with a built-in electrode that generates ions (INON) neutralizes and removes the charges on the surface of the electrostatic paper by using air ions. It is easily detached from the paper surface by the pressure of the air simultaneously ejected from the secondary ionizer 2. Stake and US material released from the paper surface are swept away from the paper surface by 0.4 to 0.8 bar compressed air sprayed from the primary air knife (3) consisting of air nozzles and stay in the casing (4). It is sucked into a dust collector having a suction force and is discharged to the outside through the flexible pipe (5). Stake and US material not removed by the first process are separated from the paper surface through the secondary ionizer (6), washed down by the secondary air knife (7) and stayed in the casing (4). The secondary brush 8 is discharged to the outside and has a function of preventing the entry of fine substances from the outside when a high pressure suction force is applied in the casing 4 in addition to the function of sweeping down the stake.

When paper is produced using this equity elimination device, it is possible to completely remove the stakes and US substances adsorbed on the surface of the paper, which will result in a high level of satisfaction from the customer due to the improvement of the print quality and the increase in sales of the paper industry. do.

Claims (1)

In order to remove the foreign matter adsorbed on the paper surface, the primary brush (1) of FIG. 2, the primary ionizer (2), the primary air knife (3) and the casing (4) composed of the air nozzle with the paper surface and the inclined angle , The secondary ionizer (6), the secondary air knife (7), and the secondary brush (8) are arranged in order to completely remove the stakes and fine substances. The fines are completely removed.
