Description

Papermaking wringer roll cartridge

Technical field

The utility model relates to a kind of papermaking instrument, refers to a kind of papermaking wringer roll cartridge especially.

Background technology

Dewatering device in the paper manufacturing systems is follow-up drying cost, and the key technology of paper molding flat degree, particularly, commonly use dewatering device mainly with two cloth interband clipping paper pulp, cooperate two dehydration wheels to roll, and pull of vacuum effect, and then reach the function of dehydration, for reaching this purpose, its dehydration wheel must constitute a glue-line at outer surface, and runs through to process at glue-line and dehydration wheel and inhale the hole, but makes two dehydration wheel elasticity roll two straps, make two straps that paper pulp is wherein extruded moisture, simultaneously, cooperate the vavuum pump effect in the dehydration wheel, more further with dewatering of pulp, in order to subsequent drying processing, this structure has following technical disadvantages:

1, adopt two dehydrations to take turns in the process that rolls, to make paper pulp surface degree not good, because two straps are when being subjected to two dehydration wheel compactings, its lines is directly printed off on the paper pulp surface, and the fiber of this paper pulp itself can display because of pressurized, thus, just causes paper pulp when drying is paper, its surface smoothness is not good, so the space of improvement is still arranged.

2, finish with drilling indirectly in the suction hole of dehydration wheel, below its aperture can't be reduced to a certain degree, generally speaking this aperture is 4MM, this aperture is relatively large to the paper pulp fine particle, so the paper pulp fine particle enters easily and stops up wherein, therefore use a period of time one by one each hole to be led to instrument, and the cleaning and dewatering wheel is inner, and then causes the puzzlement that to keep in repair often, moreover, inhale the hole because of it and finish with drilling indirectly, so the hole count in its unit are is certain, its specific area is approximately 37 percent, thus, the area of its vacuum dehydration just is restricted, and also more inhomogeneous, causes overall vacuum dehydration usefulness to detract to some extent.

The utility model content

The purpose of this utility model is to provide a kind of papermaking wringer roll cartridge that can significantly promote dewatering efficiency, increase paper molding flat degree.

To achieve these goals, technical solution of the present utility model is: a kind of papermaking wringer roll cartridge, comprise a support body, be pivoted on support body an inner core free to rotate, and the netted urceolus that is covered with outward of inner core of this device wherein, inner core is hollow form, its inner accommodation space that forms, be provided with vacuum chamber in the accommodation space, the inner core periphery is provided with one group of capacitor, the chamber bottom is provided with the suction hole that is through to the inner core accommodation space, the inner core peripheral closure is provided with the netted urceolus that paper supply is starched direct smooth support, reached vacuum dehydration, and netted urceolus is fully with each chamber top closure.

Aforesaid papermaking wringer roll cartridge, wherein suspention is provided with vacuum chamber in the inner core accommodation space, the vacuum chamber top end opening all end faces in the inner core that are tightly connected, the vavuum pump of vacuum chamber to inner core.

Aforesaid papermaking wringer roll cartridge, wherein inner core periphery spacer ring is provided with one group of groove, constitutes rib between each groove, is interval with the caulking groove that is embedded for dividing plate on inner core, each rib, and constitutes one group of chamber.

Aforesaid papermaking wringer roll cartridge, wherein netted urceolus are spliced by thick order inner plexiform layer and detailed catalogue inner plexiform layer and form.

After adopting said structure, the utility model has following two advantages at least:

1, the utility model is an interface with netted urceolus, make vacuum chamber, inhale the hole, chamber reaches full side face and evenly dewaters via interface, the aperture of this netted urceolus can be far smaller than the drilling aperture, so general paper pulp fine particle can't enter in the inner core, only can be attached on the netted urceolus, need only cooperate this moment and wash net machine water spray, just the paper pulp fine particle can be eliminated, so, just can reach the advantage that reduces the maintenance inner core, moreover the mesh of the netted urceolus of the utility model, its specific area are far longer than commonly uses boring more than one times, thus, the specific area of its vacuum dehydration just significantly promotes, and is also more even, so actual dewatering efficiency of the present utility model increases.

2, the utility model directly carries out the evenly vacuum dehydration of full week with the overall structure of inner core, netted urceolus, need not adopt and commonly use two-wheel and roll, the utility model to the pressure of paper pulp greatly about every square centimeter 250 unit, the pressure of commonly using is then at every square centimeter 450 unit, so the utility model is commonly used the enhancement effect of dwindling the paper power consumption, and paper pulp is after drying, its surface very smooth and outstanding (because of pressure less).
