Abstract
A taper pipe pulp distributor comprises a horizontal pulp distribution header pipe which has a hollow cavity; the pulp distribution header pipe is provided with a pulp feed pipe and pulp return pipes; the pulp feed pipe is arranged in the middle portion of the pulp distribution header pipe; the pulp return pipes are arranged at two ends of the pulp distribution header pipe; the cross section of the pulp distribution header pipe gradually shrinks from the pulp feed pipe to the bilateral pulp return pipes. Pulp discharge branch pipes are uniformly arranged on the external side of the pulp distribution header pipe along the length direction thereof. The flux of the pulp distribution header pipe is divided half-and-half by learning from the design of a three-way pipe. The problem of pressure reduction at the tail end which is caused by arranging the pulp feed pipe at one end is solved. Additionally, the cross section of the pulp distribution header pipe gradually shrinks from the pulp feed pipe to the bilateral pulp return pipes, thus keeping the pressure of each pulp discharge branch pipe on the pulp distribution header pipe in consistency as much as possible, and consequently avoiding the uneven pulp distribution caused by the uneven pressure of the pulp discharge branch pipes. The ratio difference between the uniformity and the aspect intensity of the finished paper is small, and the quality of the finished paper is higher.
Description
Technical field
The present invention relates to a kind of papermaking equipment, be specifically related to a kind of pulp distributing device with taper pipe.
Background technology
At present, along with the progress of science and technology, the quality requirement of paper is also more and more higher, and high-quality paper requires that paper has very little cross direction ration deviation and the good fiber-wall-element model uniformity.The quality of paper and the uniformity is become to depend primarily on the quality of paper machine pulp distributor cloth slurry performance.
Paper machine pulp distributor is that the stream of slurry send and distribution apparatus, and its effect is distributed to uniformly in head box along net is wide by online slurry, and high efficiency pulp distributor can make slurry obtain uniform distribution once entering paper machine.The pulp distributor used at present is squeezed in cloth slurry pipe by slurries by stock pump, then carry out cloth slurry by bobbin carriage.Because used cloth slurry pipe is for square, square cloth slurry pipe one side is distributed with multiple cloth plasm mouth along its length, slurries reduce gradually along cloth slurry length of tube directional pressure, affect the cloth slurry of far-end, cloth is caused to starch uneven, make into the paper uniformity and vertical transverse strength ratio large, affect into the quality of paper.
Summary of the invention
The object of the present invention is to provide a kind of pulp distributing device with taper pipe, slurries in existing square cloth slurry pipe can be solved and reduce gradually along cloth slurry length of tube directional pressure, affect the cloth slurry of far-end, cause cloth to starch uneven problem.
For achieving the above object, technical scheme of the present invention is: pulp distributing device with taper pipe, comprise the cloth slurry house steward of the level with hollow cavity, described cloth slurry house steward is provided with pulp-inlet pipe and return pipe, described pulp-inlet pipe is positioned at the middle part above cloth slurry house steward, described return pipe is positioned at the two ends of cloth slurry house steward, and described cloth slurry house steward cross section reduces to the return pipe of both sides gradually from pulp-inlet pipe; The outside of described cloth slurry house steward is evenly distributed with pulp arm along its length.
When adopting technique scheme, use for reference the design of three-way pipe, cloth has been starched house steward's subdivision flow on a fifty-fifty basis.Solve and pulp-inlet pipe is arranged in one end and problem that the terminal pressure that causes reduces.Moreover cloth slurry house steward cross section reduces to the return pipe of both sides gradually from pulp-inlet pipe, and the pressure of each pulp arm making cloth starch on house steward is consistent to the full extent, prevents the pressure inequality because of pulp arm from causing cloth to starch uneven.The uniformity and the vertical transverse strength ratio of one-tenth paper are little, become the quality of paper higher.
Further, the opposite described cloth slurry house steward being positioned at pulp-inlet pipe is provided with delivery pipe, and described delivery pipe is provided with cleaning valve.This design can directly by opening cleaning valve, and perfusion cleaning fluid cleans pulp distributing device with taper pipe.
Further, described return pipe is bent downwardly, and this design can be convenient to the realization of overfall under gravity.
Further, the cross section of described pulp-inlet pipe reduces from top to bottom successively.This design can increase flow to a certain extent, and can play dispersive pressure, the object of equalizing pressure.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of pulp distributing device with taper pipe embodiment of the present invention.
Detailed description of the invention
As shown in Figure 1, pulp distributing device with taper pipe of the present invention, comprise the cloth slurry house steward 1 of the level with hollow cavity, cloth slurry house steward 1 is provided with pulp-inlet pipe 2 and return pipe 3, and the cross section of pulp-inlet pipe 2 reduces from top to bottom successively.This design can increase flow to a certain extent, and can play dispersive pressure, the object of equalizing pressure.Return pipe 3 is bent downwardly, and this design can be convenient to the realization of overfall under gravity.Pulp-inlet pipe 2 is positioned at the middle part above cloth slurry house steward 1, and return pipe 3 is positioned at the two ends of cloth slurry house steward 1, and cloth slurry house steward 1 cross section reduces to the return pipe 3 of both sides gradually from pulp-inlet pipe 2; The outside of cloth slurry house steward 1 is evenly distributed with pulp arm 4 along its length.Opposite cloth slurry house steward 1 being positioned at pulp-inlet pipe 2 is provided with delivery pipe 5, and delivery pipe 5 is provided with cleaning valve.This design can directly by opening cleaning valve, and perfusion cleaning fluid cleans pulp distributing device with taper pipe.
The present invention has used for reference the design of three-way pipe, cloth is starched house steward 1 subdivision flow on a fifty-fifty basis.Solve and pulp-inlet pipe 2 is arranged in one end and problem that the terminal pressure that causes reduces.Moreover cloth slurry house steward 1 cross section reduces to the return pipe 3 of both sides gradually from pulp-inlet pipe 2, and the pressure of each pulp arm 4 making cloth starch on house steward 1 is consistent to the full extent, prevents the pressure inequality because of pulp arm 4 from causing cloth to starch uneven.The uniformity and the vertical transverse strength ratio of one-tenth paper are little, become the quality of paper higher.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; without departing from the inventive concept of the premise; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
