Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The utility model will be further explained with reference to the drawings.

As shown in figure 1, the papermaking fiber filtering and collecting device at least comprises a pulp storage tank 1, an outer cylinder 2, a screen cylinder 5 and a lifting auger 4.

Wherein the screen cylinder 5 is coaxially arranged within the outer cylinder 2. A lifting packing auger 4 is arranged in the outer cylinder 2 and is used for driving a motor 3 of the lifting packing auger 4 to be fixed at the upper end of the screen cylinder 5. The lower end of the outer cylinder 2 vertically extends into the pulp storage tank 1, and the lower part thereof is provided with a scum feed pipe 6 communicated with the pulp storage tank 1 so as to suck scum 9 floating on the surface of pulp 8 stored in the pulp storage tank 1. The upper part of the annular collecting chamber is provided with a scum outlet pipe 7 for discharging scum from the upper part.

The sieve drum 5 is provided with sieve pores, and an annular material collecting cavity is formed between the sieve pores and the outer drum 2. The lifting auger 4 sucks the scum 9 and then feeds the scum upwards, and fine paper pulp fibers carried in the scum 9 outwards pass through the sieve holes along with the pulp under the action of centrifugal force and enter the annular aggregate cavity. The bottom of the annular collecting cavity is provided with a fiber returning port 10 communicated to the paper pulp storage tank 1, so that the recycled pulp containing the fine paper pulp fibers flows back to the paper pulp storage tank 1.

The papermaking fiber filtering and collecting device provided by the utility model utilizes the advantages that the specific gravity of the fibers is high, the scum is lifted by the auger, and the pulp fibers are thrown out along with the pulp under the inertia effect, so that the fine pulp fibers are collected, the waste is changed into valuable, the cost is reduced, and the use of raw materials is reduced.

Specifically, 750 kg of high-quality pulp fiber can be obtained from 1 ton of waste paper (national waste), and about 190 kg of discharged general solid waste plastic and waste foam, 20 kg of sand, which contains about 40 kg of pulp fiber. The papermaking fiber filtering and collecting device can effectively collect pulp fibers mixed with waste plastics and foams, the collecting efficiency reaches about 95 percent, 3800 tons of pulp fibers can be recycled every year according to the annual processing of 10 ten thousand tons of waste paper capacity, and more than 800 ten thousand yuan can be saved every year according to the current price of 2500 yuan per ton of recycled pulp, and the economic benefit value is considerable.

In other embodiments, it is preferred that the upper part of the annular collecting chamber is provided with a cleaning device. The cleaning device has a plurality of cleaning heads which spray or rinse towards the inner wall of the outer cylinder 2, thereby avoiding excessive accumulation of fibers on the inner wall of the outer cylinder 2. Preferably, the water intake of the cleaning device extends into the bottom of the pulp storage tank 1, and the cleaning is completed by the pulp itself.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be construed as the protection scope of the present invention.
