Abstract

The utility model belongs to the technical field of the straining, comprising a frame, a screen cradle, a sieve plate, a size box, a device for regulating the level of pulp and a pulp box. The centre line of the screen cradle where a vibration device is arranged at is changed to one end of the screen cradle where pulp box is not arranged on; the longth between the terminal line of the end and the position the vibration device is arranged is 1/4-1/3 length of the screen cradle. The vibration device comprises a main shaft driven by an electrical machine and two eccentric wheels arranged on the main shaft. The sieve plate of the utility model can not be clogged by the fiber slurry residue in the paper pulp easily; the speed of screening out slurry residue is fast; the weight of the sieve plate is light; the service life is long; the height of the screen cradle is reduced to 40%-45%; the power consumption is reduced to 30%-45%.

Description

Polarization strainer

The utility model belongs to the apparatus for screening fibrous suspensions technical field.

Traditional frame plansifter that shakes, its vibrating device is arranged on the center of sieve nest, and the oscillation trajectory of screenings on sieve plate is ellipse garden shape during work, amplitude at the sieve plate two ends is same, sieve plate is easily twined by the long fiber screenings, causes the sieve plate large tracts of land to stop up, not easy-clear, so it is slow not only to make screenings sift out speed, and the increase of sieve plate weight, be easy to break, shortened service life, power consumption is big, very starches of poor quality.

The purpose of this utility model is a kind of new apparatus for screening fibrous suspensions of design, and the sieve plate of this apparatus for screening fibrous suspensions is difficult for being stopped up by the long fiber screenings in the paper pulp during work.

The utility model comprises that frame, four jiaos are with the stock tank that hangs sieve plate that sieve nest that spring is suspended on frame top and sieve nest bottom be connected as a single entity, place in the bottom of frame, the slurry case placed above the slurry position adjusting device of the slag notch of an end setting of stock tank and bottom setting, a end at sieve nest, its improvements are that vibrating device is arranged on the end that sieve nest is not placed the slurry case, distance apart from this end end line is the 1/5-2/5 of sieve nest length, and vibrating device comprises and passes sieve nest and the main shaft that is linked to each other with motor by flexible shaft coupling, is installed in two eccentric wheels on the main shaft.

The utility model is changed to an end that deviates from slurry case sieve nest with vibrating device by the center of sieve nest, the amplitude of paper pulp on sieve plate changed, end amplitude near the slurry case is little, end amplitude near vibrating device is big, because it is few near the screenings amount in the end paper pulp of slurry case, many near the screenings amount in the end paper pulp of vibrating device, therefore realized that screenings amount many places amplitude is big, the screenings amount is located the little rational deployment of amplitude less, and the utility model is compared with traditional frame plansifter that shakes has following characteristics:

1, sieve plate is difficult for being stopped up by the long fiber screenings in the paper pulp, has solved screenings and has sifted out slow-footed problem;

2, the height of the weight saving of sieve plate, sieve nest reduces 40%-45%, long service life;

3, the power of motor of vibrating device adapted reduces, and power consumption reduces 30%-45%;

4, very starch the quality height, impurely in the good slurry be lower than 0.2%.

Describe concrete structure of the present utility model in detail below in conjunction with drawings and Examples.

Accompanying drawing has provided embodiment of the present utility model, wherein:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is vertical views of the present utility model.

Among the figure: (1) is sieve nest, and (2) for hanging spring, (3) are the slurry case, (4) be frame, (5) be stock tank, (6) are sieve plate, and (7) are slurry position adjusting device, (8) be main shaft, (9) be eccentric wheel, (10) are sparge pipe, and (11) are around the property shaft coupling, (12) be motor, (13) are slag notch.

In the present embodiment, each parts selects for use metal material to make, and motor (12) is selected Y series 3 kilowatt motors for use, sieve plate (6) is gone up and is bored equally distributed brill shape hole, and top aperture is little, and following aperture is big, the small end aperture is φ 2.5-10mm, and the aperture is more little, and it is high more very to starch quality.The main shaft of vibrating device (8) is installed in sieve nest (1) and does not place slurry case (3) one ends, is 1/4 of sieve nest (1) length apart from this end end line distance.During work, connect motor (12) power supply, motor (12) rotation, drive main shaft (8) rotation by flexible shaft coupling (11), eccentric wheel (9) is rotation thereupon also, make sieve plate (6) produce vibration, filter by slurry case (3) and be placed in paper pulp on the sieve plate (6), long stapled screenings is separated with good slurry.

Claims

1, a kind of polarization pulp screen, comprise frame (4), four jiaos with hanging the sieve nest (1) that spring (2) is suspended on frame (4) top, the sieve plate (6) that bottom sieve nest (1), is connected as a single entity, the stock tank of placing in the bottom of frame (4) (5), the slag notch (13) that is provided with at an end of stock tank (5) and the slurry position adjusting device (7) of bottom setting, the slurry case of placing in the end top of sieve nest (1) (3), it is characterized in that vibrating device is arranged on the end that sieve nest (1) is not placed slurry case (3), distance apart from this end end line is the 1/5-2/5 of sieve nest (1) length, vibrating device comprises the main shaft (8) that passes sieve nest (1) and linked to each other with motor (12) by flexible shaft coupling (11), is installed in two eccentric wheels (9) on the main shaft (8).

2, according to the said polarization pulp screen of claim 1, it is characterized in that described vibrating device is arranged on the end that sieve nest (1) is not placed slurry case (3), be 1/4 of sieve nest (1) length apart from this end end line distance.
