Abstract
The utility model relates to blast pulping complete equipment which is used for pulping which comprises fibre raw material, and is mainly composed of a raw material air conveying device, a storing feeding device, a blast pulping device, a steam and pulp separation device, a pulp pool, etc. The utility model is characterized in that the blast pulping device (3) is connected with a flange seal of an expansion pipe (3-3) by a conical nozzle (3-1), wherein, the conical nozzle (3-1) which is made of a steel plate with 6 mm thickness is made into a conical seal head with 60 DEG; the surface of the conical seal head is drilled out with conical met holes with 90 DEG from outer to inner by a homogeneous distribution mode, and the diameter of each of the conical met holes is 3 mm. The length of the expansion pipe (3-3) is 780 mm, and the conical degree is between 10 DEG and 12 DEG. The steam and pulp separation device (4) is composed of a once tangential separation cylinder (4-1), a secondary radial separation cylinder (4-2) and a top separation conical seal head (4-3). The steam and pulp separation device (4) is characterized in that the met holes with 3 mm diameters are uniformly arranged on the cylinder walls of the once tangential separation cylinder (4-1), the secondary radial separation cylinder (4-2) and the top separation conical seal head (4-3).
Description
The utility model provides a kind of explosion pulping complete set of equipments, belongs to universal machine.Be mainly used in the slurrying of fibre-bearing raw material, as the slurrying of paper grade (stock) grass fiber and tobacco, food, brewage, the fiber slurrying of feedstuff industry or expanded.
Chemical method is adopted in common fiber slurrying at present mostly, is restricted owing to chemical pulping process can cause serious environmental to pollute, and there are into problems such as pulp yield is low, cost height in chemical method simultaneously.
The purpose of this utility model provides a kind of explosion pulping complete set of equipments of mechanical-physical pulping process.To overcome the problems such as serious environmental pollution that chemical pulping process causes that are extensive use of at present, owing in pulping process, do not add any chemical substance, produce so there is chemical contamination, can effectively improve into pulp yield simultaneously, have that cost is low, characteristics such as automatic controlling level and slurrying efficient height.
Explosion pulping complete set of equipments of the present utility model mainly is made up of raw material wind power transmission device (1), storage charging gear (2), explosion pulping device (3), vapour and pulp separating device (4), stock tank (5).Wherein raw material wind power transmission device (1) adopts bolt to be connected with storage charging gear (2).Explosion pulping device (3) adopts pipe flange to be tightly connected with vapour and pulp separating device (4).It is characterized by the middle Conic nozzle (3-1) of explosion pulping device (3) is connected with expansion tube (3-3) flange seal by ball valve (3-2), wherein Conic nozzle (3-1) is made 60 degree conical heads by the 6mm steel plate, and the Conic nozzle surface gets out Ф 3mm 90 degree taper mesh from evenly distributing outside to inside.Expansion tube (3-3) length is 780mm, tapering 10-12 degree.
Separate conical head (4-3) and form by a tangential separation tube (4-1), secondary radial separation tube (4-2), top in the vapour and pulp separating device (4), wherein evenly make Ф 3mm mesh on a tangential separation tube (4-1), secondary radial separation tube (4-2) and top separation conical head (4-3) barrel.
Accompanying drawing 1 is a primary structure schematic diagram of the present utility model.
Accompanying drawing 2 is vapour, slurry separator structural representation.
The utility model embodiment is as follows, have cyto-architectural fibrous raw material by raw material wind power transmission device (1), store charging gear (2) and pack in the explosion pulping device (3), add 1.0-2.5MP.Saturated vapor, under the saturated vapor effect, fiber is by the steam swollen, fibre crystallinity improves, the degree of polymerization descends, at high temperature lignin is softening, plastic, hemicellulose partly decomposes.By technological requirement through boost-after pressurize-decompression is boosted again, open ball valve (3-2) and make material enter expansion tube (3-3).When the material that is full of steam pressure reduced pressure suddenly, because the rapid expansion effect of medium, the part lignin was stripped from, and fiber is dissociated becomes slurry.Under alternate load and action of pressure, because the Conic nozzle surface gets out the effect of Ф 3mm 90 degree taper mesh from evenly distributing outside to inside, it is unimpeded to have guaranteed that steam pressure passes, and can stop slurry, and Conic nozzle has stronger rigidity and functional reliability.Slurry after expansion tube (3-3) explosion enters vapour and pulp separating device (4) by pipeline, after the vapour slurry tangentially enters separator (4), slurry is descending along the inner walls rotation, and rotating through Ф 3mm mesh along a tangential separation tube (4-1) outer wall, steam enters secondary separation radial separation tube (4-2), along the purpose that reaches the secondary radial separation after outer wall passes Ф 3mm mesh.Conical head (4-3) is separated on the top can effectively change the slurry up direction, and can carry out first separation, and a small amount of slurry that passes Ф 3mm mesh can flow into stock tank along conical inboard wall.The separated back of steam in the slurry is discharged by pipeline, and slurry enters stock tank (5).
Claims (2)
1, a kind of explosion pulping complete set of equipments, by raw material wind power transmission device (1), store charging gear (2), explosion pulping device (3), vapour and pulp separating device (4), five most of compositions such as stock tank (5), it is characterized in that the Conic nozzle (3-1) in the explosion pulping device (3) is connected with expansion tube (3-3) flange seal by ball valve (3-2), wherein Conic nozzle (3-1) is made 60 degree conical heads by the 6mm steel plate, the conical head surface gets out the 90 degree taper mesh of Ф 3mm from evenly distributing outside to inside, expansion tube (3-3) length is 780mm, tapering 10-12 degree.
2, explosion pulping complete set of equipments according to claim 1, it is characterized in that vapour and pulp separating device (4) is mainly separated conical head (4-3) and formed by a tangential separation tube (4-1), secondary radial separation tube (4-2), top, steel plate or steel tube surface that its cylinder and conical head adopt are evenly made Ф 3mm mesh.
