Abstract
The invention discloses a paper pulp flow regulation device for an air-cushioned headbox.The paper pulp flow regulation device is characterized by comprising a flow limiting valve pipe in longitudinal arrangement, a separable pulp flow cover is arranged at the top of the flow limiting valve pipe, and the side wall of the pulp flow cover is provided with a pulp flow round hole array formed by pulp flow round holes; the flow limiting valve pipe comprises a tubular valve pipe body and a tubular connection clamping pipe, a tubular overflow pipe is arranged in the valve pipe body, the side wall of the overflow pipe is provided with an overflow round hole array formed by overflow round holes, and a movable limiting steel ball is arranged in the overflow pipe.Once the pressure of a paper pulp supply pipe fails to reach a preset value, the limiting steel ball presses a conical flow limiting surface to block a paper pulp supply passage, so that reliability and stability in pulp supply are greatly improved.In addition, due to the overflow round holes distributed in the overflow pipe, flocculation of fibers can be effectively prevented to avoid pipeline blockage.
Description
Technical field
The present invention relates to a kind of papermaking apparatus, more precisely, be the paper pulp stream quantity regulating device of a kind of air cushioned headbox.
Background technology
Air cushioned headbox is a kind of common paper making equipment, is mainly used in the flow-control of paper pulp, thus obtaining uniform pulp flow and flow velocity.The pressure of the liquid-supplying system of existing air cushioned headbox is susceptible to fluctuation, causes fiber wadding in head box to gather, the stability of impact stream slurry.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus providing the paper pulp stream quantity regulating device of a kind of air cushioned headbox.
The above-mentioned technical problem of the present invention is addressed mainly by following technical proposals:
A kind of paper pulp stream quantity regulating device of air cushioned headbox, it is characterized in that, the paper pulp stream quantity regulating device of described air cushioned headbox comprises a longitudinally disposed flow-limiting valve pipe, the top of described flow-limiting valve pipe is provided with a separable stream slurry lid, the sidewall of described stream slurry lid is provided with a stream slurry array of circular apertures being made up of stream slurry circular hole, described flow-limiting valve pipe comprises the valve tube body of a tubulose and the Connection Card pipe of a tubulose, the inside of described valve tube body is provided with the overflow pipe of a tubulose, the sidewall of described overflow pipe is provided with an overflow array of circular apertures being made up of overflow circular hole, the bottom of described valve tube body is provided with the current limliting conical surface of a taper, a mobilizable spacing steel ball it is provided with in described overflow pipe.
As preferred embodiment of the present invention, described flow-limiting valve pipe is that foundry goods is one-body molded, and the size of the internal diameter of described overflow pipe and described spacing steel ball adapts.
When the paper pulp stream quantity regulating device of the air cushioned headbox of the present invention has the advantage that use, the paper pulp supply pipe external for Connection Card Guan Yuyi of flow-limiting valve pipe is connected by user, and under the effect of compression pump, serosity enters in overflow pipe.When the pressure that paper pulp supplies pipe reaches a preset value, spacing steel ball rises, and serosity directly flows out from overflow circular hole, and on the last lip flowing out to head box from stream slurry circular hole.The pressure supplying pipe once paper pulp is unable to reach preset value, and spacing steel ball will push down the current limliting conical surface, is blocked by paper pulp feed path, substantially increases the reliability and stability of serosity supply.Further, since overflow pipe is provided with multiple overflow circular hole, can effectively prevent the wadding of fiber from gathering, it is prevented that line clogging.It is simple that the pulp flow of this air cushioned headbox regulates apparatus structure, and effect is obvious, with low cost, practical.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention being made apparent clear and definite defining.
As shown in Figures 1 to 6, the paper pulp stream quantity regulating device 1 of this air cushioned headbox comprises a longitudinally disposed flow-limiting valve pipe 2, the top of this flow-limiting valve pipe 2 is provided with a separable stream slurry lid 3, the sidewall of this stream slurry lid 3 is provided with a stream slurry array of circular apertures being made up of stream slurry circular hole 31, this flow-limiting valve pipe 2 comprises the valve tube body 21 of a tubulose and the Connection Card pipe 22 of a tubulose, the inside of this valve tube body 21 is provided with the overflow pipe 23 of a tubulose, the sidewall of this overflow pipe 23 is provided with an overflow array of circular apertures being made up of overflow circular hole 24, the bottom of this valve tube body 21 is provided with the current limliting conical surface 25 of a taper, a mobilizable spacing steel ball 4 it is provided with in this overflow pipe 23.
This flow-limiting valve pipe 2 is that foundry goods is one-body molded, and the size of the internal diameter of this overflow pipe 23 and this spacing steel ball 4 adapts.
During use, as depicted in figs. 1 and 2, paper pulp supply pipe external with for the Connection Card pipe 22 of flow-limiting valve pipe 2 is connected by user, and under the effect of compression pump, serosity enters in overflow pipe 23.When the pressure that paper pulp supplies pipe reaches a preset value, spacing steel ball 4 rises, and serosity directly flows out from overflow circular hole 24, and on the last lip flowing out to head box from stream slurry circular hole 31.The pressure supplying pipe once paper pulp is unable to reach preset value, and spacing steel ball 4 will push down the current limliting conical surface 25, is blocked by paper pulp feed path, substantially increases the reliability and stability of serosity supply.
Further, since overflow pipe 23 is provided with multiple overflow circular hole 24, can effectively prevent the wadding of fiber from gathering, it is prevented that line clogging.
It is simple that the pulp flow of this air cushioned headbox regulates apparatus structure, and effect is obvious, with low cost, practical.
It is not limited to this, any change expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with claims protection defined.
