There is grout outlet；The position of described grout outlet be higher than pulp-inlet pipe with enter the position that stock tank connects.
As the improved technical scheme of this utility model, also include flashboard adjusting handle, described flashboard adjusting handle is installed
On casing, and the flashboard that is in transmission connection, for adjusting the gap between flashboard and box bottom.
As the improved technical scheme of this utility model, also include aulaeum, top lip of slice；Described aulaeum is fixedly connected on
Grout outlet；Described top lip of slice is installed on the top of grout outlet and leaves pulp gap and between aulaeum.
As the further improved technical scheme of this utility model, also include adjusting bracket；Described adjusting bracket includes handss
Wheel, connecting seat and some adjusting rods；Described adjusting rod one end is connected with top lip of slice, and the other end is installed on connecting seat；Institute
State connecting seat to be installed on casing；Described handwheel is in transmission connection and realizes adjusting rod is carried out with the tune of short transverse position in mounting seat
Section.
Beneficial effect
Low speed head box of the present utility model, by arranging several pulp-inlet pipes entering stock tank bottom, and using entering stock tank
With the difference in height going out stock tank, slurry stream and current are transformed into the homogeneous slurry stream being covered with paper machine full width, and fibrous suspension does not produce
Raw Xu Juhejiang road, is effectively ensured slurry and sprays homogeneous and stability, can be widely applied for low speed（Minimum reach 3m/
Min), the paper production of high grammes per square metre, the such as separator paper of accumulator and other long stapled manufacturings.

Specific embodiment
Purpose and technical scheme for making this utility model embodiment are clearer, implement below in conjunction with this utility model
The accompanying drawing of example, is clearly and completely described to the technical scheme of this utility model embodiment.Obviously, described embodiment
It is a part of embodiment of the present utility model, rather than whole embodiments.Based on described embodiment of the present utility model,
The every other embodiment that those of ordinary skill in the art are obtained on the premise of without creative work, broadly falls into this practicality
Novel protected scope.
The implication of " inside and outside " described in this utility model refers to respect to equipment itself, inside sensing equipment
Direction be interior, otherwise be outer, rather than the specific restriction to equipment mechanism of the present utility model.
The implication of " connection " described in this utility model can be between being directly connected between part or part
By being indirectly connected with of other parts.
A kind of low speed head box as shown in accompanying drawing 1-4, including casing 1 and flashboard 2；Described flashboard 2 is along its length
Be arranged in inside casing 1, and by casing 1 be divided into into stock tank 11 with go out stock tank 12 two parts；Described enter stock tank 11 bottom even
Several pulp-inlet pipes 8 are installed；Described go out stock tank 12 be provided with grout outlet, and the position of grout outlet is higher than the position of pulp-inlet pipe 8
Put；The position going out stock tank 12 bottom surface in casing described in the present embodiment 1 is higher than position into stock tank 11 bottom surface, and grout outlet is arranged out
The lower end of stock tank 12；Flashboard 2 is located at into stock tank 11 and the intersection going out stock tank 12, leaves between flashboard 2 and casing 1 bottom simultaneously
Gap is it is therefore intended that the connection that ensures into stock tank 11 and go out slurry between stock tank 12；Here, the effect of flashboard 2 is according to slurry
The height of liquid level stops the laitance in slurry.In order to adjust the gap between flashboard 2 and casing 1 bottom, also include flashboard and adjust handss
Wheel 6, described flashboard adjusting handle 6 is installed on casing 1, and the flashboard 2 that is in transmission connection, and rotates handwheel 3 and realizes to flashboard 2 and casing
The regulation in 1 gap between bottom.
It is fixedly connected with aulaeum 9, in the present embodiment, aulaeum 9 is secured by bolts in out at described grout outlet
At slurry mouth；The top of grout outlet is provided with top lip of slice 7, leaves pulp gap between top lip of slice 7 and aulaeum 9, on controlling
Gap between labial lamina 7 and aulaeum 9 can control the cross direction ration of pulp concentration, pulp；
And in order to realize the adjustability in gap between top lip of slice 7 and aulaeum 9, also include adjusting bracket；Described adjusting bracket
Including handwheel 3, connecting seat 4 and some adjusting rods 5, described adjusting rod 5 one end is connected with top lip of slice 7, and the other end is installed on
