Description

Paper pulp solution suction filtration device

Technical Field

The utility model relates to the technical field of extraction and suction filtration equipment for detecting the concentration and the beating degree of paper pulp, in particular to a paper pulp solution suction filtration device.

Background

With the implementation of plastic-forbidden regulations, international demand is continuously increasing, and the demand in regions of Japan and Korean, European Union, North America and the like is increasing at a rate of nearly 20% every year, and in recent years, some states in the United states carry out financial subsidies on environment-friendly tableware using straws, so that the demand is increased in a crossing manner. In recent years, the market prospect of tableware in China is all the way good, the market demand is huge, and the tableware becomes a trillion-level large-scale industry. Straw environmental protection tableware, plant straw fiber textile and the like are applications with high added value and high technology content in the field of straw comprehensive utilization, so the straw tableware is the development trend of the future environmental protection tableware.

With the increasing size of companies, the production and detection devices need to be further optimized, improved and perfected. Such as: the detection of the pulp concentration and the beating degree in the pulping process is increasingly difficult due to the increase of the yield. In the prior art, a small vacuum pump is used for suction filtration in a pulping working section for detecting pulp concentration and beating degree, and the detection is delayed because the vacuum pump cannot be used due to the fact that fine wet pulp fibers enter an oil filling box in the pump, so that much trouble is brought to detection work; and the vacuum pump is in the state of not having a rest almost, often leads to the pump body to generate heat because of using frequently and stops work, and the vacuum pump damages the probability very big, can effectively serve production in order to ensure the detection achievement, reduces the detection deviation because of the instrument problem brings, consequently needs a high-efficient suction filter device.

SUMMERY OF THE UTILITY MODEL

Aiming at the problems, the utility model provides a paper pulp solution suction filtration device, which solves the problems that paper pulp detection cannot be met and equipment is easily damaged due to vacuum pumping of a vacuum pump.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a paper pulp solution suction filtration device, includes filter equipment and evacuating device, filter equipment includes the funnel, strains the pocket and sets up the buchner flask under the funnel, strain the pocket and pass through the mounting setting in the funnel, evacuating device includes interconnect's air compressor machine and overhead tank, and the overhead tank can cushion the pressure that the overhead tank conveying was come safely, effectively avoids the safety risk because of the too high pressure that leads to of overhead tank transport, be connected with the exhaust tube between overhead tank and the buchner flask, be equipped with the spiral control valve on the exhaust tube, can adjust vacuum pressure's size at any time.

As optimization, the funnel is buchner funnel, strain the whole column type that is of pocket, just strain the material of pocket and be the cotton, conveniently fully filter the water in the thick liquid.

Preferably, the fixing piece is a circular ring with a clamping groove in the bottom surface, and a plurality of supporting ribs are arranged on the inner edge of the clamping groove.

Preferably, a sealing plug is arranged between the funnel and the filter flask.

The utility model has the beneficial effects that: according to the pulp solution suction filtration device provided by the utility model, the filter bag is formed by selecting cloth with relatively dense porosity and sewing the cloth by itself, so that the influence on a detection result caused by slurry overflow in the suction filtration process is prevented; through the cooperation of air compressor machine and overhead tank, make suction filtration pressure more stable, the suction filtration time shortens, and the suction filtration effect is better, improves the detection rate of thick liquid concentration and kowtow degree, has reduced the detection error because of the equipment reason brings, and the testing result is more accurate.
