Description
Technical field
The utility model relates to a kind of suction flat box, belongs to papermaking dehydration equipment field.
Background technology
In paper production, dewatering to wet paper is important manufacturing procedure.Suction flat box is the main dehydration equipment in papermaking operation, by it being connected with vavuum pump, making to form negative pressure in casing, thus carrying out suction dehydration to the wet paper be attached on screen cloth.For alleviate screen cloth and suction flat box dehydration panel between wearing and tearing, usually on dehydration panel, arrange protruding wearing layer, wearing layer has the material such as aluminium oxide ceramics, glass.Existing wearing layer in use for some time, because wearing and tearing cause smoothness to reduce, increases the friction of the screen cloth of delivery wet paper, causes the damage of screen cloth and dewatering box, raise production cost.Existing wearing layer directly bonds fixing, during use, under the dragging of screen cloth, is easy to come off, and produces " key " phenomenon.
Utility model content
According to above the deficiencies in the prior art, technical problem to be solved in the utility model is: provide a kind of suction flat box, have self-lubricating property, coefficient of friction is low, long service life, and fixation, without key phenomenon, reduces production cost.
Suction flat box described in the utility model, comprise casing, casing is provided with dehydration panel, dehydration panel comprises backing board, and on backing board, fixed intervals distribute and the bar shaped base be parallel to each other, and arrange dewatering hole between adjacent two bar shaped bases, dewatering hole two ends are equipped with can pull sealing strip, bar shaped base arranges wear rib, and wear rib is connected by dovetail configuration with bar shaped base, and wear rib adopts silicon nitride material.
Because silicon nitride has self lubricity, coefficient of friction is low, during use, greatly can reduce the frictional force between the screen cloth of delivery wet paper and dehydration panel, reduce mutual wearing and tearing between the two, increase the service life, reduce production cost.Wear rib is connected with bar shaped base by dovetail configuration, and transversely fixation is reliable, and wear rib is difficult to come off, and avoids key phenomenon occurs.Can finely tuning vacuum by pull sealing strip of dewatering hole two ends.
Described bar shaped base has dovetail groove, and corresponding wear rib bottom is provided with dovetail, and dovetail inserts in dovetail groove.
Described wear rib and bar shaped base contacts face bond fixing by binding agent, fixing further by bonding, strengthen the attachment force between wear rib and bar shaped base, binding agent is filled in the micro gap between wear rib and bar shaped base, avoid the fine motion of wear rib, increase the service life.
Described backing board and bar shaped base are integrated, and backing board is bolted on casing, can carry out integral replacing, casing reusable edible to dehydration panel.
Described backing board and bar shaped base are glass steel material.
Three vacuum chambers are provided with in described casing, adjacent vacuum room is separated by dividing plate, each vacuum chamber is connected with vacuum tube respectively, vacuum chamber is connected with vavuum pump by vacuum tube, an original casing arranges a vacuum chamber, when combinationally using, needs multiple casing parallel arranged to use, cause the interval between adjacent vacuum room comparatively large, use inconvenience.By being integrated in a casing by three vacuum chambers, greatly facilitate use.
The brace summer of inclination and transverse direction is set in described vacuum chamber, increases support strength.
During use, the screen cloth carrying wet paper is walked on dehydration panel, and under the negative-pressure ward effect of vavuum pump, moisture content enters in casing along dewatering hole, thus dewaters to wet paper.Screen cloth is laterally advanced along wear rib, produces horizontal thrust to wear rib, and wear rib, under dovetail configuration and bonding fixation, fixedly secures on bar shaped base, avoids producing key phenomenon.
Compared with prior art, the beneficial effect that the utility model has is:
This suction flat box is connected by dovetail configuration with bar shaped base by arranging wear rib, realizes lateral locking, and fixation is reliable, without key phenomenon; By arranging the wear rib of silicon nitride material, have self-lubricating property, coefficient of friction is low, long service life; By being provided with three vacuum chambers in casing, greatly facilitating use, strengthening water separation capability.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Fig. 1 ~ 2, this suction flat box comprises casing 1, casing 1 is provided with dehydration panel 2, dehydration panel 2 comprises backing board 201, on backing board 201, fixed intervals distribute and the bar shaped base 203 be parallel to each other, and arrange dewatering hole 204 between adjacent two bar shaped bases 203, and dewatering hole 204 communicates with box house through backing board 201, dewatering hole 204 two ends are equipped with can pull sealing strip, and sealing strip can be finely tuned vacuum.Bar shaped base 203 is arranged wear rib 202, wear rib 202 adopts silicon nitride material, and wear rib 202 is connected by dovetail configuration with bar shaped base 203, and this dovetail configuration for have dovetail groove on bar shaped base 203, corresponding wear rib 202 bottom is provided with dovetail, and dovetail inserts in dovetail groove.Also can adopt bar shaped base 203 top that dovetail is set, the mode of dovetail groove is set in wear rib 202 bottom.Wear rib 202 bond fixing with bar shaped base 203 contact surface by binding agent, by fixing of binding agent and dovetail configuration, realize lateral locking, fixation reliably, without key phenomenon.Backing board 201 and bar shaped base 203 are integrated, convenient processing, and adopt glass steel material, and backing board 201 is bolted on casing 1, change, casing 1 be can be recycled after convenient wearing and tearing.
As shown in Figure 3, be provided with three vacuum chambers 5 in casing 1, adjacent vacuum room 5 is separated by dividing plate 6, and each vacuum chamber 5 is connected with vacuum tube 5 respectively, arranges the brace summer 4 of inclination and transverse direction in vacuum chamber 5.By being integrated in a casing 1 by three vacuum chambers 5, greatly facilitating use, enhancing suction dehydrating function.
The course of work:
During use, carry screen cloth walking on dehydration panel 2 of wet paper, under the negative-pressure ward effect of vavuum pump, moisture content enters in casing 1 along dewatering hole 204, thus dewaters to wet paper.Screen cloth is laterally advanced along wear rib 202, produces horizontal thrust to wear rib 202, and wear rib 202, under dovetail configuration and bonding fixation, fixedly secures on bar shaped base 203, avoids producing key phenomenon.
