Abstract
The utility model discloses a vacuum water sucking system of a paper making machine. The vacuum water sucking system comprises a vacuum pump and a header pipe which is connected with the vacuum pump, wherein the header pipe is connected with a net part water sucking box, a vacuum couch roll and a press part moisture absorption box respectively; the vacuum pump is a turbine vacuum pump; and branch pipes for connecting the net part water sucking box, the vacuum couch roll and the moisture absorption box with the header pipe are provided with filtrate pumps respectively. By using the vacuum water sucking system of the paper making machine, since the turbine vacuum pump of which a pump body and an impeller are not in contact with sewage is used in place of the conventional water-ring vacuum pump, the service life of the vacuum pump is greatly prolonged, and meanwhile, high-temperature gas produced after an air flow is compressed to do work during work of the vacuum pump can also be recycled.
Description
Technical field
The utility model relates to a kind of paper machine, relates to the vacuum dehydration system in a kind of paper machine specifically.
Background technology
Comprise mainly that at paper-making process wet end drainage, press dewatering, cylinder dried, press polish batch; And carry out cutting and rewinding or cut producing roll web and flat board; In its one initial wet end drainage technical process,, also need adopt usually with the vacuum dehydration system and absorb the most of moisture content that is spread out in the paper pulp on the guipure for better paper pulp being dewatered; Existing vacuum dehydration system mainly comprises a water-ring vacuum pump and the coupled house steward who connects; On house steward, also be connected with several moisture absorption casees usually, a negative pressure that forms when working through water-ring vacuum pump is absorbed the most of moisture content in the paper pulp; But owing to water-ring vacuum pump is by the driven by motor impeller water ring water acting in the vavuum pump to be produced vacuum; The pump housing and impeller cause the life-span of vavuum pump to be reduced in the etch that receives sewage and perishable and cause wearing and tearing, also cause the production cost of whole vacuum dehydration system to improve simultaneously.
The utility model content
For overcoming above-mentioned defective, the utility model aims to provide a kind of both efficient, and is energy-conservation again, has the paper machine vacuum dehydration system of longer life.
For achieving the above object; The technical scheme that the utility model adopts is: a kind of vacuum dehydration system of paper machine; Comprise vavuum pump and the house steward who is connected with vavuum pump, be connected with wet end suction box, suction couch roll and moisture absorption case on the said house steward respectively, said vavuum pump is a turbine vacuum pump.
Being in charge of that said wet end suction box, suction couch roll and moisture absorption case are connected with house steward is respectively equipped with filtrate pump.
Adopted the vacuum dehydration system of the paper machine of the utility model; Do not replace traditional water-ring vacuum pump owing to do not contact the pump housing and impeller the turbine vacuum pump of sewage; Is greatly enhanced the service life of vavuum pump; Air-flow was compressed the high-temperature gas that produces after the acting and can also be recovered utilization when simultaneously, vavuum pump was worked.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The 1-vavuum pump, house steward 2-, 3-wet end suction box, 4-moisture absorption case, 5-is in charge of, 6-filtrate pump, 7-suction couch roll.
The specific embodiment
As shown in Figure 1; The utility model discloses a kind of vacuum dehydration system of paper machine, comprise vavuum pump 1 and the house steward 2 who is connected with vavuum pump 1, be connected with wet end suction box 3, suction couch roll 7 and moisture absorption case 4 on the said house steward 2 respectively; When vavuum pump 1 work, can form a negative pressure; Thereby take the moisture content in the paper pulp away through wet end suction box 3, suction couch roll 7 and moisture absorption case 4, in sum, with the structure basically identical of the vacuum dehydration system of existing paper machine.
The innovative point of the vacuum dehydration system of the paper machine of the utility model is that said vavuum pump 1 is turbine vacuum pump.Compare with traditional water-ring vacuum pump; Turbine vacuum pump is that the impeller with at a high speed rotation directly does work to air and forms stable vacuum; Its pump housing and impeller do not contact with sewage, have avoided the corrosion of sewage to the pump housing and impeller, thus the service life of having improved vavuum pump.
In practical application, usually being in charge of of being connected with house steward 2 be respectively equipped with filtrate pump 6 on 5 at said wet end suction box 3, suction couch roll 7 and moisture absorption case 4.
Claims (2)
