Abstract
The invention discloses a vacuum water suction device of a paper machine. The vacuum water suction device solves the problems that the service life of a vacuum pump of an existing vacuum water suction device is short, and the abrasion resistance of a net part vacuum water suction box face plate is not high. The vacuum water suction device comprises a turbine vacuum pump, a suction pipeline connected with the turbine vacuum pump, a net part vacuum water suction box, a vacuum couch roll and moisture absorption boxes, wherein net part vacuum water suction box, the vacuum couch roll and the moisture absorption boxes are all connected with the suction pipeline through branch pipes. The net part vacuum water suction box comprises a water suction box body with a face plate, wherein protection layers made of ceramic materials are arranged on the upper surface and the lower surface of the face plate respectively. The vacuum water suction device is reasonable in structural design and long in service life, and the abrasion resistance of the face plate of the net part vacuum water suction box is high.
Description
[technical field]
The present invention relates to a kind of water absorber, specifically, relate to a kind of paper machine vacuum dehydration equipment.
[background technology]
Existing paper is mainly drawn by paper machine manufacture, in paper-making process, needs to dehydrate paper pulp, in a whole set of paper making equipment, normally completes the work of paper pulp moisture removal by vacuum water absorber.
Existing vacuum water absorber, usually adopt liquid-ring type or Roots vaccum pump to provide suction, then the moisture of l Water Paper part is taken away by wet end suction flat box under negative pressure, and for water-ring vacuum pump, this kind of mode exists following two defects:
(1) owing to being produce vacuum by driven by motor impeller to the water acting of water ring in vavuum pump when water-ring vacuum pump works, therefore, the pump housing and impeller are easily subject to the erosion of sewage, cause the pump housing and impeller to be worn, thus cause service life of vacuum pump to reduce;
(2) panel of wet end suction flat box adopts nylon or high-molecular polythene material to make usually, becomes and turned-down edge because nylon can produce stream under paper machine high-speed friction condition, causes wet end suction flat box sealing and vacuum to decline; And high-molecular polythene panel hardness is low, coefficient of friction large, easily produce concavo-convex wearing and tearing forming web in using, therefore, the ABRASION RESISTANCE of existing wet end vacuum suction box face plate is quite bad.
[summary of the invention]
The object of the present invention is to provide a kind of paper machine vacuum dehydration equipment, mainly solve existing vacuum water absorber and there is the low and problem that wet end vacuum suction box face plate ABRASION RESISTANCE is bad of service life of vacuum pump.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of paper machine vacuum dehydration equipment, comprises turbine vacuum pump, the suction channel be connected with this turbine vacuum pump, and all by wet end suction flat box, suction couch roll and moisture absorption case that arm is connected with this suction channel; Described wet end suction flat box comprises the suction box main body being provided with panel, and the upper and lower surface of this panel is equipped with the protective layer be made up of ceramic material; Described panel itself is provided with humidity sensor, and be then provided with in panel outside the warning device be electrically connected with this humidity sensor, this warning device is built-in with data processing circuit.
Compared with prior art, the present invention has following beneficial effect:
The present invention adopts turbine vacuum pump as the vavuum pump of paper making equipment, instead of traditional water-ring vacuum pump, due to the structure design characteristic of turbine vacuum pump, its operationally the pump housing and impeller can not with waste water, therefore, it can guarantee the service life of paper making equipment vavuum pump.In addition; the present invention is all provided with in the upper and lower surface of wet end vacuum suction box face plate the protective layer be made up of ceramic material; because ceramic material has the feature of high rigidity, high-wearing feature and high oxidative; therefore; it is under the use not affecting suction box, overcomes the defect that wet end vacuum suction box face plate hardness is low and not wear-resisting.

Fig. 1 is structural representation of the present invention.
Fig. 2 is the sectional view of wet end suction flat box.
Wherein, the parts name that Reference numeral is corresponding is called:
1-turbine vacuum pump, 2-suction channel, 3-wet end suction flat box, 31-panel, 4-protective layer, 5-suction couch roll, 6-arm, 7-moisture absorption case, 8-warning device.
[detailed description of the invention]
Below in conjunction with drawings and Examples, the invention will be further described, and embodiments of the present invention include but not limited to the following example.
Embodiment
As shown in Figure 1, 2, the present invention includes turbine vacuum pump 1, the suction channel 2 be connected with this turbine vacuum pump 1, and all by wet end suction flat box 3, suction couch roll 5 and moisture absorption case 7 that arm 6 is connected with this suction channel 2.As shown in Figure 2, described wet end suction flat box 3 comprises the suction box main body being provided with panel 31, and this upper and lower surface of panel 31 is equipped with the protective layer 4 be made up of ceramic material.When the present invention works, utilize the negative pressure that turbine vacuum pump 1 work produces, just by wet end suction flat box 3, suction couch roll 5 and moisture absorption case 7, the moisture in paper pulp can be taken away, turbine vacuum pump 1 is prior art, and its operation principle the present embodiment is not introduced in detail.
Because the impeller in turbine vacuum pump 1 directly produces stable vacuum to air acting, and the pump housing and impeller all not with waste water, therefore, the present invention has that moisture removal is effective, long service life and advantage with low cost.
Meanwhile, panel 31 inside is provided with the humidity sensor for detecting humidity, be then provided with the warning device 8 be connected with this humidity sensor in panel 31 outside, this warning device is built-in with data processing circuit.
Operationally, the data of detection are transferred to data processing circuit by humidity sensor, finally have warning device to give the alarm.
In the present invention, data processing circuit adopts conventional prior art, and the present invention is not described in detail.
According to above-described embodiment, just the present invention can be realized well.
