Abstract
The utility model discloses a gravity dewatering box, which comprises a box body and panels, wherein the panels are arranged above the box body and consist of transverse strips, and channel structures are arranged between the panels and the box body. Through the edge design with the channel structures, higher dewatering rate is ensured through improving the utilization rate of the coanda effect. Ceramic materials are adopted, and the friction between the panels is obviously reduced, so a paper machine can stably operate, and the constant productivity and the stable net structure can be obtained.
Description
Technical field
The utility model relates to a kind of gravity dehydration case, particularly relates to a kind of gravity dehydration case that is used for the papermaking initial procedure.
Background technology
In the papermaking starting stage, the physical method that utilizes paper pulp flow velocity and paper machine operation speed to combine dewaters to the l Water Paper page or leaf.Paper pulp with the speed near net, is sprayed onto online from the lip of head box equably.Along with for no reason fourdrinier wire moves forward, lean on gravity or vacuum force, the moisture in the paper pulp is just discharged from mesh.In the time of along with slurry dehydration on the net, fiber in the paper pulp and filler etc. all are deposited on online and form the l Water Paper page or leaf.In this process, just dewater and not by means of any external force through online gravity dehydration case.Because it self physical characteristic, gravity dehydration the case only scope within 10 meters of wet end front ends are suitable for.But, in dehydration, can consume lot of energy, and the paper machine is unstable in running.
Summary of the invention
The utility model technical problem to be solved is, a kind of gravity dehydration case is provided, and uses less energy consumption to obtain dehydrating effect efficiently, makes operation that the paper machine can be stable and obtain constant production capacity and stable wet end structure.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of gravity dehydration case, comprise casing and panel, and panel is located on the casing; It is characterized in that: described panel is made up of horizontal stripe, is provided with groove structure between described panel and the casing.
Aforesaid gravity dehydration case is characterized in that: the material of said panel is pottery.
Compared with prior art, the utility model has the advantages that: have the edge designs of groove structure, guaranteed higher dehydration rate through the utilization rate that improves Coanda effect; Adopt ceramic material, the friction between panel descends obviously, makes operation that the paper machine can be stable and obtain constant production capacity and stable wet end structure.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the edge contour figure of the utility model.
The specific embodiment
For further disclosing the technical scheme of the utility model; Now be described with reference to the accompanying drawings the embodiment of the utility model: like Fig. 1, shown in 2, a kind of gravity dehydration case comprises casing 1 and ceramic panel 2; Ceramic panel 2 is located on the casing 1, and this ceramic panel 2 is made up of horizontal stripe.Be provided with groove structure 3 between ceramic panel 2 and the casing 1.
Have the edge designs of groove structure, guaranteed higher dehydration rate through the utilization rate that improves Coanda effect; Adopt ceramic material, the friction between panel descends obviously, makes operation that the paper machine can be stable and obtain constant production capacity and stable wet end structure.
More than, the basic design and the basic principle of the utility model have been set forth through introduction to listed embodiment.But the utility model never is limited to above-mentioned listed embodiment, and every equivalent variations, improvement of doing based on the technical scheme of the utility model reaches and deliberately become of inferior quality behavior, all should belong to the protection domain of the utility model.
Claims (2)
1. a gravity dehydration case comprises casing and panel, and panel is located on the casing, it is characterized in that: described panel is made up of horizontal stripe, is provided with groove structure between described panel and the casing.
2. gravity dehydration case according to claim 1 is characterized in that: the material of said panel is pottery.
