Abstract
The utility model relates to a buffer device for controlling a basis weight of a paper machine. The buffer device for controlling the basis weight of the paper machine is arranged at an inlet of an approach flow pipeline of a fan pump, of a cross structure, and arranged along the inside wall of the inlet of the approach flow pipeline, penetrates through the inlet of the approach flow pipeline from top to bottom, and equally divides the inlet of the approach flow pipeline into four portions. Compared with the prior art, by a flow disturbing principle of the buffer device, the buffer device for controlling the basis weight of the paper machine guarantees the stability of approach flow and accordingly the basis weight of produced paper sheets is stable due to the facts that when enriched water passes through the approach flow pipeline of the fan pump and after being split by special flow disturbing plates, the flow velocity is slowed down, a flow vortex is not easy to form, and simultaneously air cannot be mixed in.
Description
Technical field
The utility model relates to a kind of paper production device, especially relates to a kind of quantitative buffer unit of paper machine of controlling.
Background technology
Loss and the minimizing water consumption of paper machine in order to save fiber, the device that reclaims enriched water is arranged on paper machine constant part, exactly white water recycle is mixed with slurry by fan pump after the white water chest again and pump, dewater under effect through forming web and centrifugal force, enriched water is recycling use again.the enriched water pond of Periformer Crescent in design on the ground, but due to the fan pump design and installation at subsurface approximately in the melt pit of 6 meters, from the enriched water pond to fan pump by the flow line road of an end diameter 1016mm reducing to an end diameter 600mm, (the fan pump pump-out is: minimum 29556l/min, max 58331l/min), under the effect of high flow capacity like this, stream when normal operation from the white water chest to the fan pump send the porch easily to form the current whirlpool, the current whirlpool is greatly easily sneaked into large quantity of air, steam-water mixing directly causes the starching flow unstable, the starching flowed fluctuation causes the fluctuation of paper delivery longitudinal basis weight large, cause the papery quality fluctuation, exceed the page longitudinal basis weight fluctuation range that normal device is produced.Easily form simultaneously cavitation erosion and damage fan pump equipment, shorten equipment life, increase manufacturing cost.
The utility model content
The purpose of this utility model is exactly the quantitative buffer unit of control paper machine that provides a kind of improving product quality for the defective that overcomes above-mentioned prior art existence, guarantees production stability.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of quantitative buffer unit of paper machine of controlling, be arranged on the porch in the flow line road of fan pump, this device is decussate texture, along the madial wall setting of flow line road entrance, the entrance that runs through the flow line road from top to bottom is slit into four parts with the entrance average mark in flow line road.
Described buffer unit is the corrosion resistant plate that the argon arc welding welding production obtains decussate texture.
Described buffer unit is welded to connect porch in the flow line road through argon arc welding.
Described buffer unit is connected with the inwall coupling of flow line road entrance.
By the flow-disturbing principle of buffer unit, enriched water to fan pump flow line road by the time, after should special spoiler shunting, flow velocity slows down, and is difficult for formation current whirlpool.The air that can not sneak into simultaneously guarantees the starching stability of flow, and the page quantification of producing is corresponding stable.
Compared with prior art, the utlity model has following advantage:
(1) guarantee that enriched water enters paper machine fan pump and is difficult for producing the current whirlpool, guarantee the enriched water stability of flow, solution causes the quantitative fluctuation problem of appearance because of flow shakiness or entrained air, reduce the loss that causes because product is defective, improving product quality, improving production efficiency;
(2) reduce sneaking into of air, reduce possibility of cavitation erosion, extend fan pump service life, reduction production equipment cost allowance;
(3) guarantee production stability.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
A kind of quantitative buffer unit of paper machine 1 of controlling is arranged on entrance 2 places, flow line road of fan pump, as shown in Figure 1, this device is decussate texture, along the madial wall setting of flow line road entrance 2, run through flow line road entrance 2 from top to bottom, flow line road entrance 2 average marks are slit into four parts.
Buffer unit 1 is obtained and argon arc welding is welded to connect at entrance 2 places, flow line road through the argon arc welding welding production by corrosion resistant plate.Buffer unit 1 mates mutually with the shape of the inwall of flow line road entrance 2.In the present embodiment, buffer unit 1 be about 1800mm, wide 1200mm, high 500mm.
By the flow-disturbing principle of buffer unit 1, enriched water to fan pump flow line road by the time, after should special spoiler shunting, flow velocity slows down, and is difficult for formation current whirlpool.The air that can not sneak into simultaneously guarantees the starching stability of flow, and the page quantification of producing is corresponding stable.
Claims (4)
1. control the quantitative buffer unit of paper machine for one kind, be arranged on the porch in the flow line road of fan pump, it is characterized in that, this device is decussate texture, madial wall setting along flow line road entrance, the entrance that runs through the flow line road from top to bottom is slit into four parts with the entrance average mark in flow line road.
