Description
Technical field
The invention belongs to the experimental provisions of field of papermaking, and in particular to a kind of rectangular handshcet former of use for laboratory.
Background technique
The handshcet former that field of papermaking is related to is mainly with preparing handsheet, for detecting paper performance, evaluate material performance with
And influence of the adjusting process condition to paper performance, handshcet former common at present is round and without plain boiled water circulatory function, round
Handsheet is size-limited in later period coating waste water, is unfavorable for paper performance after evaluation post-processing, does not have plain boiled water circulation function
Just the influence to paper performance can not can be recycled by plain boiled water in simulated production.
Summary of the invention
To solve the above-mentioned problems, the present invention provides that a kind of structure is simple, easy to operate, the laboratory of plain boiled water circulatory function
With rectangular handshcet former.
In order to achieve the above object, the present invention designed by the rectangular handshcet former of use for laboratory, including grooving, station,
Plain boiled water bucket, the forming trench bottom are connect with aspiration tube, there is backing plate on the station, and the backing plate passes through hinge and grooving
Connection, the backing plate side connect with vacuum tube, has support plate and pressing handwheel on the backing plate, have in the support plate several
There is forming device on dewatering hole, the backing plate, there is plain boiled water bucket under the station.
Further embodiment is that compressed air valve is installed in the aspiration tube, the compressed air valve connection compression
Air door switch.
Further embodiment is that vacuum valve is installed on the vacuum tube, and the vacuum valve connects vacuum threshold switch.
Further embodiment is that the support plate is connect by drainpipe with plain boiled water bucket, and draining is installed on the drainpipe
Valve, the drain valve connect drainage valve switch.
Further embodiment is that the plain boiled water bucket is connect by outlet pipe with water pump, and the outlet pipe is equipped with blowdown valve,
The water pump connects pump switch.
Further embodiment is that have upper hose on the water pump, and the upper hose water outlet is on grooving.
Further embodiment is that the forming device includes square frame and forming net.
The obtained rectangular handshcet former of use for laboratory of the present invention, compared with traditional handshcet former, handsheet web dimension is larger,
Meet the needs of Paper Coating processing, a handsheet can satisfy the detection of multiple indexs, save the time, reduce into
This.With plain boiled water circulatory function, influence of the plain boiled water recycling to paper performance can be simulated, it is easy to operate, it is easy to use.

Embodiment 1
Referring to Fig. 1, the rectangular handshcet former of use for laboratory of the present embodiment description includes grooving 1, station 2, plain boiled water bucket 3, will be at
Shape dress is set 11 and is placed in support plate 8, is then aligned 1 bottom of grooving with backing plate 5, tightens pressing handwheel 9, guarantees grooving
1 does not occur water leakage situation with 5 contact portion of backing plate；Plain boiled water bucket 3 is injected water into, pump switch 22 is pressed, the water warp in plain boiled water bucket 3
Outlet pipe 19, by the way that in 23 injection molding slot 1 of upper hose, water level reaches certain altitude in grooving 1, presses water pump by water pump 20
Switch 22, water pump 20 stop working, and paper pulp is added in grooving 1；Press compressed air valve switch 13, compressed air valve
12 open, and air, even into grooving 1, is generated uniform bubble, uniformly stir pulp suspension by aspiration tube 4；Again
Compressed air valve switch 13 is pressed, compressed air valve 12 is closed, and air-blowing is stopped；Press drainage valve switch 18, drain valve 17
It opens, water is discharged into plain boiled water bucket 3 by forming net 26 and dewatering hole 10 by drainpipe 16；When paper pulp on forming device 11 at
