Description

A kind of pulp filter dehydration device

technical field

The utility model relates to the technical field of separation treatment, in particular to a pulp filtration and dehydration device.

Background technique

The use of waste paper to produce new paper can realize the recycling of paper. The process is to first grind the waste paper into pulp, and then make the pulp into paper. In the process of making pulp from waste paper, the silt in the waste paper is mixed into the pulp , in order to ensure the quality of the paper, it is necessary to discharge the silt in the pulp. In this process, the pulp fibers will also be discharged together. The pulp accounts for about 40% of the sewage, causing serious waste.

During the dehydration process of waste paper, the viscosity of the waste paper slurry is relatively high, which increases the difficulty of filtration and separation, and it is easy to block the fine filter, requiring frequent washing and maintenance, which seriously affects the work efficiency and consumes a lot of manpower and time. Production efficiency and output.

Utility model content

The purpose of the utility model is to provide a pulp filtration and dehydration device to solve the deficiencies of the prior art.

For realizing the utility model purpose, the technical scheme that adopts is:

A pulp filtration and dehydration device, comprising a low support, a pulp storage bucket and a high support, characterized in that a dehydration tank is provided on the low support, and an inverted cone-shaped filter screen fixed to its inner wall is arranged in the dehydration tank, and the inverted cone-shaped The lower end of the filter screen is provided with a flow channel, and the flow channel extends into the slurry storage tank; the outer wall of the dehydration tank is provided with a gear ring, the lower bracket is provided with a motor, and the output shaft of the motor is provided with a gear, which is connected with the gear ring; A positive cone filter is provided above the high bracket, and a matching positive cone plate is provided below the positive cone filter. The lower end of the positive cone extends into the dehydration tank and has an interval with the inner wall of the dehydration tank; The high bracket is provided with an annular groove, and the lower end of the positive conical filter net extends into the annular groove; a pulp nozzle is arranged directly above the positive conical filter net.

Further, a water outlet is provided at the bottom of the dehydration tank.

Further, a slurry outlet is provided at the lower part of the slurry storage tank.

Further, the normal conical filter screen is fixedly connected to the normal conical plate through a bracket rod.

Further, the pore diameter of the positive conical filter is larger than the pore diameter of the reverse conical filter.

The beneficial effect of the utility model is that the mixed solution containing pulp from the pulper flows into the top of the forward cone filter through the pulp nozzle, and the mixed solution flows from the top of the forward cone filter to the forward cone filter During the bottom process, the pulp of the mixed solution falls from the filter hole of the forward cone filter screen into the forward cone plate, the impurities in the mixed solution enter the annular groove, and the pulp flows into the reverse cone filter net from the bottom edge of the forward cone plate After dehydration treatment, the dehydrated pulp enters the pulp storage tank; as the motor drives the dehydration tank to rotate, the dehydration tank drives the inverted cone filter to rotate, so that the dehydration of the pulp entering the inverted cone filter is better, and at the same time, it avoids easy blockage of pulp The inverted cone filter seriously affects the dehydration effect, and it is very inconvenient to clean at the same time.

Description of drawings

Fig. 1 is a schematic structural view of a pulp filtration and dehydration device provided by the utility model.

detailed description

The utility model will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.

Fig. 1 has shown the paper pulp filtration and dehydration device provided by the utility model, comprises low support 1, dehydration tank 2, ring gear 3, high support 4, inverted cone filter screen 5, annular groove 6, positive conical plate 7, Positive conical filter screen 8, support rod 9, flow channel 11, pulp storage barrel 12, gear 13, motor 14 and pulp outlet 15. The low bracket 1 is provided with a dehydration tank 2, and the dehydration tank 2 is provided with an inverted conical filter 5 fixed to its inner wall, and the lower end of the inverted conical filter 5 is provided with a flow channel 11, and the flow channel 11 extends into the slurry In the barrel 12, the lower end of the pulp storage barrel 12 protrudes from the dehydration tank 2; the outer wall of the dehydration tank 2 is provided with a gear ring 3, the low support 1 is provided with a motor 14, and the output shaft of the motor 14 is provided with a gear 13, and the gear 13 and the gear ring 3 Cooperate connection; above the high support 4 is provided with a positive cone filter 8, below the positive cone filter 8 is provided with a matching positive cone plate 7, the lower end of the positive cone plate 7 extends into the dehydration tank 2, and there is an interval with the inner wall of the dehydration tank 2; the high bracket 4 is provided with an annular groove 6, and the lower end of the positive conical filter screen 8 extends into the annular groove 6; the positive conical filter screen 8 is directly above A pulp nozzle 10 is provided; the bottom end of the dehydration tank 2 is provided with a water outlet; the lower part of the storage tank 12 is provided with a pulp outlet 15; 9 national connections; the aperture of the positive cone filter 8 is larger than the aperture of the reverse cone filter 5.

Working principle: the pulp-containing mixed solution from the pulper flows into the top of the forward cone filter 8 through the pulp nozzle 10, and the mixed solution flows from the top of the forward cone filter 8 to the forward cone filter 8 During the bottom process, the pulp of the mixed solution falls from the filter hole of the forward conical filter screen 8 onto the forward conical plate 7, the impurities in the mixed solution enter the annular groove 6, and the pulp flows into the inverted cone from the bottom edge of the forward conical plate 7 Dehydration process is carried out on the filter screen 5, and the dehydrated pulp enters the pulp storage tank 12; because the motor 14 drives the dehydration tank 2 to rotate, the dehydration tank 2 drives the inverted cone filter screen 5 to rotate, so that the pulp entering the inverted cone filter screen 5 It is better to dehydrate the pulp, and at the same time avoid that the pulp is easy to block the inverted cone filter screen 5, which will affect the dehydration effect, and it is very inconvenient to clean.
