Description
Technical field
The present invention relates to the papermaking equipment technical field, relate in particular to a kind of pressure pulp screen.
Background technique
Pulp cleaner is one of requisite visual plant in the waste paper processing process, and screening can be removed plurality of impurities such as lumps, sicker, hot-melt object, chip etc., and the quality quality of final products depends on the height of screening effeciency to a great extent; Comprise in the waste paper processing process at the pulping and paper-making production line now, the sieve overwhelming majority of using is pressurized screen, the screening area of pressurized screen mainly is made up of a columnar screen cylinder and rotor, when rotor turns round, epitrochanterian rotor will sieve from the paper pulp of liquid feeding pump producing waterpower pulse near sieve plate face place.Pressurized screen reliability and working efficiency be decided by rotor, but existing rotor shaft seal is mechanical seal, shortcoming is: the life-span is low, replacings is difficult, maintenance expenses is high, operating cost is big, and needs press water to lubricate; Packing_seal because packing gland is positioned at a side of liquid, can't solve a difficult problem of adjusting sealing load as a kind of sealing means better than mechanical seal, also can't be applied to the shaft sealing of pulp cleaner.
Summary of the invention
Technical problem to be solved by this invention provides a kind of employing packing_seal, and be easy to housekeeping operation, simple and reliable, operating cost is low, do not need that press water is lubricated, the shaft sealer of the pressure pulp screen of high life.
For solving the problems of the technologies described above, technological scheme of the present invention is: the shaft sealer of pressure pulp screen, comprise the bearing support that is fixedly mounted on the pulp cleaner housing bottom, the two ends of described bearing support are installed with two bearings, be installed with bearing cap on the bearing support of the exterior edge face of described two bearings respectively, by the rotatable rotor shaft that is installed in the described bearing support of two bearings, it is power intake that described rotor shaft is positioned at the outer end of pulp cleaner housing, the end that described rotor shaft is positioned at the pulp cleaner housing is installed with the pulp cleaner rotor, the end of described bearing seat in described pulp cleaner housing is installed with the packing seat, be provided with packing in the described packing seat, also be provided with the packing gland device of adjusting packing_seal pressure on the described packing seat, described rotor shaft is provided with seal ring corresponding to axle sleeve detachably is installed on the shaft part of described packing between described axle sleeve and the described rotor shaft; Be provided with airtight space between described packing seat and the described bearing support, described packing gland device is installed in the described airtight space.
As a kind of improvement, described packing gland device comprises packing gland and symmetrically arranged packing gland adjustment bolt, in the confined space that described packing gland is provided with between described packing seat and described bearing support, be provided with the packing gland that is through to outer power intake one end of described bearing support in the described bearing support and adjust bolt hole, described packing gland adjustment bolt passes described packing gland adjustment bolt hole and is threaded with described packing gland, and described packing gland adjustment bolt is rotatable to be installed in the described packing gland adjustment bolt hole.
Owing to adopted technique scheme, the shaft sealer of pressure pulp screen, comprise the bearing support that is fixedly mounted on the pulp cleaner housing bottom, the two ends of described bearing support are installed with two bearings, be installed with bearing cap on the bearing support of the exterior edge face of described two bearings respectively, by the rotatable rotor shaft that is installed in the described bearing support of two bearings, it is power intake that described rotor shaft is positioned at the outer end of pulp cleaner housing, the end that described rotor shaft is positioned at the pulp cleaner housing is installed with the pulp cleaner rotor, the end of described bearing seat in described pulp cleaner housing is installed with the packing seat, be provided with packing in the described packing seat, also be provided with the packing gland device of adjusting packing_seal pressure on the described packing seat, described rotor shaft is connected to axle sleeve corresponding to detachable fixed cover on the shaft part of described packing, is provided with seal ring between described axle sleeve and the described rotor shaft; Be provided with airtight space between described packing seat and the described bearing support, described packing gland device is installed in the described airtight space; After adopting said structure, replace mechanical seal to become possibility with packing_seal, and leak-down rate is low, is easy to housekeeping operation, operating cost is low, and then has improved the working efficiency of pressurized screen.
