The durable vacuum water absorption device comprises a Roots vacuum pump body provided with an air inlet, a sucking pipeline connected with the air inlet of the Roots vacuum pump body, a netted vacuum water absorption box connected with the sucking pipeline through a branch pipe, a vacuum couch roll and moisture absorption boxes. Shafts and rotors are arranged in the Roots vacuum pump body. An air outlet pipeline and an air supplement port are arranged on the Roots vacuum pump body, cooling coils are arranged in the air outlet pipeline, and fins are fixed on the cooling coils. The netted vacuum water absorption box comprises a water absorption box main body provided with a panel, and protective layers made of ceramic materials are arranged on both the upper surface and the lower surface of the panel. The durable vacuum water absorption device disclosed in the invention has the advantages of reasonable structural design, long service life and high abrasion resistance of the panel of the netted vacuum water absorption box.
Description
[technical field]
The present invention relates to a kind of water absorber, specifically, relate to a kind of durable type paper machine vacuum water absorber.
[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 Roots vaccum pump, this kind of vacuum dehydration mode exists following two defects:
(1) easily temperature is too high in the course of the work for traditional Roots vaccum pump, and thus easily occur aging phenomenon, this has not only had a strong impact on the normal operation of Roots vaccum pump, and shortens its service life;
(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 the panel of existing wet end suction flat box is quite bad.
[summary of the invention]
The object of the present invention is to provide a kind of durable type paper machine vacuum water absorber, 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 durable type paper machine vacuum water absorber, comprise the Roots vaccum pump body being provided with air inlet, the suction channel be connected with this Roots vaccum pump body air inlet, and all by wet end suction flat box, suction couch roll and moisture absorption case that arm is connected with this suction channel; Be respectively equipped with axle and rotor in described Roots vaccum pump body, this Roots vaccum pump body be also respectively equipped with wind pipe and wind-supplying mouth, and be also provided with cooling coil in this wind pipe, this cooling coil is also fixed with fin; 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, and is also coated with the sealant for preventing pipe leakage on the whole surface of suction channel.
Described sealant is made by water-repellent paint.
Compared with prior art, the present invention has following beneficial effect:
The present invention is provided with cooling coil and fin on Roots vaccum pump body, heat transfer sheet area during Roots vacuum pump work can be improved, improve its heat exchange efficiency, thus significantly reduce the operating temperature of Roots vaccum pump, prevent it from occurring aging phenomenon, extend the service life of Roots vaccum 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.In a word, structure of the present invention is simple, and reasonable in design, reliable, maintenance cost is low, low production cost.
[accompanying drawing explanation]
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-Roots vaccum pump body, 2-axle, 3-rotor, 4-air inlet, 5-wind pipe, 6-wind-supplying mouth, 7-cooling coil, 8-fin, 9-suction channel, 10-wet end suction flat box, 101-panel, 11-protective layer, 12-suction couch roll, 13-arm, 14-moisture absorption case.
[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 the Roots vaccum pump body 1 being provided with air inlet 4, the suction channel 9 be connected with this Roots vaccum pump body 1 air inlet, and all by wet end suction flat box 10, suction couch roll 12 and moisture absorption case 14 that arm 13 is connected with this suction channel 9; Be respectively equipped with axle 2 and rotor 3 in described Roots vaccum pump body 1, this Roots vaccum pump body 1 be also respectively equipped with wind pipe 5 and wind-supplying mouth 6, and be also provided with cooling coil 7 in this wind pipe 5, this cooling coil 7 is also fixed with fin 8.As shown in Figure 2, described wet end suction flat box 10 comprises the suction box main body being provided with panel 101, and this upper and lower surface of panel 101 is equipped with the protective layer 11 be made up of ceramic material.Owing to being provided with cooling coil 7 and fin 8, therefore, the present invention can reduce its operating temperature in time when Roots vaccum pump body 1 works, thus protects Roots vaccum pump body 1 well.And the upper and lower surface of wet end vacuum suction box face plate is all provided with 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 existing wet end vacuum suction box face plate hardness is low and not wear-resisting.The present invention has reliable, long service life and advantage with low cost.
Meanwhile, be also coated with at the whole outer surface of suction channel 9 sealant be made by water-repellent paint, thus the sealing of pipeline is improved greatly.
According to above-described embodiment, just the present invention can be realized well.
