Abstract
The utility model belongs to the technical field of paper making machinery and particularly relates to a head box, which comprises a box body, a pulp inlet device, a pulp distributor, a pulp homogenizer and a pulp spray device. A pneumatic pulse system is fixedly arranged on a movable lip plate of the pulp spray device. The pneumatic pulse system is electrically connected with a computer control system. The magnitude of an opening between the movable lip plate and an inner bottom plate of the box can be freely adjusted through the pneumatic pulse system and the computer control system. The pulp distributor is a pulp distribution component which is provided with three stepped holes inside. The pulp homogenizer comprises two rectification and pulp homogenization rolls which are arranged in parallel at the inner lower part of the box body. The head box has the advantages that the design is reasonable, the flowing speed and the concentration of pulp can be automatically adjusted, the automation level is high, the pulp surface flowing speed is stable, the difference of gram weight of paper can be guaranteed, the overall quality of the paper is high, the pulp is evenly and stably distributed when the paper making machine rotates at high speed, and the head box is suitable for popularization and implementation.
Description
Technical field
The utility model belongs to papermaking equipment technical field, particularly relates to a kind of head box.
Background technology
The first operation of paper machine is paper stock online, and be the slurry that starching pump is sent here as its main task of head box of paper stock Internet device, from the circulation of pipeline slurry, become slurry stream homogeneous, that rectangular, its width equates with paper machine, and its longitudinal flow velocity uniformity, speed and quality that the quantitative homogeneity of head box and stability are directly connected to papermaking.And at present the contained head box of paper machine exists the fluctuation of slurry stream uneven, slurry surface current speed is not steady, and the defect that can not accurately control of slurry surface current speed, thereby is difficult to guarantee the grammes per square metre gap of paper, and the total quality of paper is poor.
Summary of the invention
The technical problems to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art exactly, and provides a kind of reasonable in design, can automatically regulate plasma flow velocity and concentration effect, automaticity is high, slurry surface current speed steadily, can guarantee the grammes per square metre gap of paper, the head box that paper total quality is high.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of head box, comprise casing, enter sizing device, pulp distributor, homogenizer and refractory gunning equipment, on the contained movable labial lamina of described refractory gunning equipment, be fixed with air pulsing system, air pulsing system is electrically connected to computerized control system, by air pulsing system and computerized control system can free adjustment described in the size of opening between movable labial lamina and casing inner bottom plating.
Described pulp distributor is provided with the cloth slurry element of three stepped holes in being.
Described homogenizer comprises two rectification doctor-rolls that be arranged in parallel that are positioned at casing bottom.
Described enter the sizing device side of being pyramidal structure enter to starch house steward.
The beneficial effect of technical solutions of the utility model is:
1, structurally, the utility model head box comprises casing, enters sizing device, pulp distributor, homogenizer and refractory gunning equipment, on the contained movable labial lamina of described refractory gunning equipment, be fixed with air pulsing system, air pulsing system is electrically connected to computerized control system, reasonable in design; By air pulsing system and computerized control system can free adjustment described in the size of opening between movable labial lamina and casing inner bottom plating, thereby control and can automatically regulate plasma flow velocity, concentration effect by computer, automaticity is high, and, slurry surface current speed steadily, the grammes per square metre gap that has guaranteed paper, the total quality of paper is high.
2, structurally, pulp distributor described in the utility model is provided with the cloth slurry element of three stepped holes in being, cloth slurry element adopts three stepped holes to form, full width inhomogeneities that can fine compensation whitewashing, thus obtain good dispersion effect, reasonable in design; Described homogenizer comprises two rectification doctor-rolls that be arranged in parallel that are positioned at casing bottom, this doctor-roll is on the one hand by changing geometry and the size of runner, slurry stream is evenly mixed with steering procedure in deceleration, acceleration, increase on the other hand the flow resistance of slurry stream, can redistribute, change, and complete in this course the neat and well spaced requirement to slurry stream, reasonable in design, when paper machine is run up, slurry is even, stable distributes, and homogenate rectification effect is good.
3, to sum up, the utility model head box is reasonable in design, can automatically regulate plasma flow velocity and concentration effect, automaticity is high, and slurry surface current speed steadily, can guarantee the grammes per square metre gap of paper, paper total quality is high, and when paper machine runs up, slurry is evenly distributed, stablizes, and is suitable for promotion and implementation.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail, wherein:
Fig. 1 is the structural representation of the utility model head box;
Sequence number in figure: 1, casing, 2, enter sizing device, 3, pulp distributor, 4, homogenizer, 5, refractory gunning equipment, 6, movable labial lamina, 7, air pulsing system.
the specific embodiment
Embodiment mono-:
Referring to Fig. 1, in figure, the utility model head box, comprise casing 1, enter sizing device 2, pulp distributor 3, homogenizer 4 and refractory gunning equipment 5, on the contained movable labial lamina 6 of described refractory gunning equipment 5, be fixed with air pulsing system 7, air pulsing system is electrically connected to computerized control system, by air pulsing system and computerized control system can free adjustment described in the size of opening between movable labial lamina and casing inner bottom plating.
Described pulp distributor 3 is provided with the cloth slurry element of three stepped holes in being.
Described homogenizer 4 comprises two rectification doctor-rolls that be arranged in parallel that are positioned at casing bottom.
It is described that to enter sizing device 2 be square pyramidal structure enters to starch house steward.
The foregoing is only the schematic specific embodiment of the utility model; not in order to limit scope of the present utility model; any those skilled in the art is not departing from equivalent variations and the modification of making under the prerequisite of the utility model design and principle, all should belong to the scope of the utility model protection.
