Problems solved by technology

[0002] At present, the screening machines used do not have the function of defrosting, and the pulp must be deflated first and then enter the screening machine for screening, which causes a lot of undissolved fiber bundles to be discharged as tailings, wasting a lot of resources. The energy consumption of the defibrillation device is also increased while the deflation is carried out first, wasting a lot of energy

Embodiment 1

[0014] Embodiment one: if figure 1 As shown, the screening machine with decompression function includes a casing 1, and the first pressure screen unit 21, the second pressure screen unit 22 and the third pressure screen unit 23 are connected in series in the casing 1, and the The first pressure screen unit 21, the second pressure screen unit 22 and the third pressure screen unit 23 have a common rotor shaft 3 that drives its rotor to rotate; the first pressure screen unit 21 is provided with a pulp inlet 21a, a well A pulp outlet 21c, a residual pulp outlet 21b, the second pressure screen unit 22 is provided with a pulp inlet 22a, a good pulp outlet 22c, and a residual pulp outlet 22b, and the third pressure screen unit 23 is provided with a pulp inlet Port 23a, good pulp outlet 23c, residual pulp outlet 23b, a pulp disintegrator 4 is installed between the residual pulp outlet 21b of the first pressure screen unit 21 and the pulp inlet 22a of the second pressure screen unit 22...

Embodiment 2

[0015] Embodiment two: if figure 2 As shown, the structure is basically the same as that of Embodiment 1, except that a pulp disintegrator 4 is installed between the residual pulp outlet 21b of the first pressure screen unit 21 and the pulp inlet 22a of the second pressure screen unit 22 , the slurry outlet 22b of the second pressure screen unit 22 is connected with the slurry inlet 23a of the third pressure screen unit 23 .

Embodiment 3

[0016] Embodiment three: as image 3 As shown, the structure is basically the same as that of Embodiment 1, except that a pulp disintegrator 4 is installed between the residual pulp outlet 22b of the second pressure screen unit 22 and the pulp inlet 23a of the third pressure screen unit 23 , the slurry outlet 21b of the first pressure screen unit 21 is connected with the slurry inlet 22a of the second pressure screen unit 22 .

[0017] Of course, we can directly make the partition between the second pressure screen unit 22 and the third pressure screen unit 23 in Embodiment two or the first pressure screen unit 21 and the second pressure screen unit 21 in Embodiment three for the convenience of manufacture. The dividing plate between the pressure screen units 22 is removed and just connected.

Abstract

The invention discloses a sieving machine with fluffing function and comprises a machine shell and at least two pressurized screen units that are arranged inside the machine shell and serially connected with each other, and have a common rotor spindle that drives a rotor thereof to rotate; the pressurized screen units have a pulp inlet, an accepted pulp outlet and a residue pulp outlet; the residue pulp outlet of the fore pressurized screen unit is communicated with the pulp inlet of the back pressurized screen unit, and a pulp fluffing machine is at least arranged at one position between the residue pulp outlet of the fore pressurized screen unit and the pulp inlet of the back pressurized screen unit; the fluffing machine is arranged to improve the fluffing function of the sieving machine, the residue pulp outlet at a first level or a second level of a multi-segment sieve is directly connected with the same fluffing machine, and pulp is fluffed then led into a sieving region in next level, thus reducing the possibility that non-fluffed fasciculus is taken as tailings and discharged out from the machine, and saving raw materials; furthermore, the residue pulp and the tailings instead of total pastes are fluffed, thus greatly lowering the energy consumption of fluffing and saving energy.

Description

technical field [0001] The invention relates to a screening machine, in particular to a screening machine with a defrosting function. Background technique [0002] At present, the screening machines used do not have the function of defrosting, and the pulp must be deflated first and then enter the screening machine for screening, which causes a lot of undissolved fiber bundles to be discharged as tailings, wasting a lot of resources. The energy consumption of the defibrillation device is also increased when the defibration is carried out first, and a large amount of energy is wasted. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a screening machine with decompression function which can save resources and greatly reduce decompression energy consumption. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a screening machine with a decompression ...
