Abstract
The utility model discloses a rotating drum for a plane valve drum-type vacuum pulp washer, which comprises a left semi-drum, a right semi-drum, an intermediate cylinder and a rotating drum surface lattice. The left semi-drum is connected with a driving side spindle nose, the right semi-drum is connected with an operation side spindle nose, a filtrate outlet is arranged on the right semi-drum, and the rotating drum surface lattice has a tapered structure, so as to quicken filtrate flowing speed, reduce flowing resistance, improve the production capacity of the pulp washer and the feeding dryness of pulp, and eliminate the buoyancy impact during operation of the rotating drum.
Description
Technical field
The utility model relates to a kind of plane valve drum vacuum pulp washing machine rotary drum, is widely used in that slightly washing and starching of the various slurries of enterprises in pulp and paper industry washed and each section floats the back washing.
Background technology
The drum-type vacuum pulp washing machine drum surface lattice chamber of domestic production at present is a horizontal structure, one end of lattice chamber has the outlet for the filtrate circulation, filtrate resistance when flowing through the HORIZONTAL PLAID chamber is big, and flow velocity is slow, thereby influences the production capacity of wash engine and the blanking mass dryness fraction of slurry.End plate is contained at the two ends of rotary drum, makes whole drum form the hollow structure of a sealing, and rotary drum is installed in the cell body, and when putting into slurry in the cell body, rotary drum is subjected to bigger buoyancy, thereby influences the serviceability of equipment.
Summary of the invention
Problem to be solved in the utility model provides a kind of plane valve drum vacuum pulp washing machine rotary drum, and this structure not only can avoid rotary drum to be subjected to the influence of buoyancy in running, can also solve filtrate suffered influence of resistance greatly in flow process.
For addressing the above problem, the technical solution adopted in the utility model is:
A kind of plane valve drum vacuum pulp washing machine rotary drum, comprise a left side half drum, right half drum, middle cylindrical shell and drum surface lattice chamber, a described left side half drum is connected with the transmission side spindle nose, right half drum is connected with the fore side spindle nose, right half drum is provided with filtrate (liquid, and it is characterized in that: described drum surface lattice chamber is a pyramidal structure.
Below be the utility model for further improvement of these options:
The internal diameter of described drum surface lattice chamber is pursued successively to the end near right half drum by an end that rouses near a left side half and subtracts.
Improve as another kind:
The internal diameter of described drum surface lattice chamber is pursued successively to the end of rousing near a left side half with near the end of right half drum respectively by the middle part and subtracts.
Half drum barrel body and half drum hub are drawn together in a left side half bulge, pass through the support post support and connection between described half drum barrel body and the half drum hub.
The utility model adopts technique scheme, pyramidal structure is adopted in drum surface lattice chamber, the internal diameter of described drum surface lattice chamber near an end of a left side half drum near right half drum, one end successively by subtract or the internal diameter of described drum surface lattice chamber from middle position respectively near the end of a left side half drum and near the end of right half drum successively by subtracting, thereby accelerate the flowing velocity of filtrate, reduced the drag effects in the flow process; Remove the end plate of rotary drum transmission side, change the spoke type structure into, change rotary drum into inside and outside connection by original airtight hollow structure, the inside and outside liquid level difference of rotary drum is zero during duty, the production capacity of wash engine and the blanking mass dryness fraction of slurry have been improved, the buoyancy effect when having eliminated the rotary drum duty.
Below in conjunction with accompanying drawing the utility model is further specified.
