Description
Technical Field
The utility model relates to a paper deacidification technical field, more specifically the utility model relates to a fixing device for paper deacidification that says so.
Background
According to incomplete statistics: the pH value of the paper literature in 20-30 years of the 20 th century in China is below 4.0 and is in a severe acidification state, and the pH value of the paper literature in 50 years is below 5.0 and is in a severe acidification state. During the slow aging process of the paper, the acidification degree of the paper is directly related to the deterioration speed, and the paper acidification can cause the reduction of the folding strength of the paper, thereby causing the breakage of the paper. Deacidification technology has become one of the most important measures for paper protection.
The paper is placed on the workbench panel of deacidification equipment, if not reliably fixed, at the process of spraying deacidification liquid and towards, under the gas injection effect of spray gun, the paper is very easily blown away, deacidification liquid can not evenly reliably be sprayed on the paper, and deacidification quality very can guarantee.
SUMMERY OF THE UTILITY MODEL
The utility model provides a fixing device for paper deacidification has overcome above-mentioned defect, and this device utilizes negative pressure principle (the paper upper and lower face of face formation pressure differential) reliably to fix the paper on the table board for in the spray gun cross work process, the paper can reliably adsorb fixedly, guarantees spraying deacidification operating mass with rated load.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a fixing device for paper deacidification, includes table panel, pipeline and air exhauster, and table panel's inside is equipped with the groove of induced drafting, is equipped with the adsorption zone on the table panel, set up a plurality of holes of induced drafting that run through table panel on the adsorption zone, the hole of induced drafting is linked together with the groove of induced drafting, and the groove of induced drafting is linked together with the one end of pipeline, and the other end and the air exhauster of pipeline are linked together.
The working process is as follows: when the exhaust fan works, air above the workbench panel enters the air suction grooves through the plurality of air suction holes in the workbench panel, flows through the pipeline, enters the fan inlet and then is taken out of the outlet of the exhaust fan through the power of the exhaust fan to be discharged into the atmosphere. Forming a complete air circuit.
Lay the paper on the workstation panel and cover the back with the hole of induced drafting, the groove of induced drafting of paper lower part, the air in the pipeline is outwards taken out by the air exhauster, even partial hole of induced drafting does not cover by the paper, because the air exhauster flow is greater than the air input of the hole of induced drafting for the downthehole air of induced drafting of paper lower part becomes more rarefied, forms the negative pressure, makes the paper adsorb to fix on table surface with the pressure differential that produces above and below the paper.
Furthermore, the air suction holes are arranged on the workbench panel at equal intervals. When the equidistant distribution of hole of induced drafting helps adsorbing the paper for the paper atress is even, makes the paper adsorbed more stable.
Furthermore, the end part of the air suction hole on the workbench panel is provided with a fillet. The fillet can avoid by the tip edges and corners scratch of the hole of induced drafting by adsorbed paper.
Furthermore, the aperture of the air suction hole is 1.5mm-6 mm.
Furthermore, the distance between the air suction holes arranged on the working table panel is 10mm-20 mm.
Furthermore, a first filter screen is arranged in the middle of the air suction hole. The first filter screen can prevent foreign matters from entering the air suction groove through the air suction hole on the table top plate, and further blocking a pipeline or damaging the exhaust fan.
Furthermore, a second filter screen is arranged at the end part of the air pipe, which is contacted with the air suction groove. The second filter screen can prevent foreign matters from entering the air suction groove through the air suction hole on the table board, and further blocking a pipeline or damaging the exhaust fan.
Further, the area of the adsorption area is smaller than or equal to the area of the adsorbed paper. So that the paper is absorbed more stably.
Compared with the prior art, the utility model beneficial effect who has is:
the utility model discloses simple structure, the practicality is strong. When the exhaust fan works, air above the workbench panel enters the air suction grooves through the plurality of air suction holes in the workbench panel, flows through the pipeline, enters the fan inlet and then is taken out of the outlet of the exhaust fan through the power of the exhaust fan to be discharged into the atmosphere. Forming a complete air circuit. Lay the paper on the workstation panel and cover the back with the hole of induced drafting, the groove of induced drafting of paper lower part, the air in the pipeline is outwards taken out by the air exhauster, even partial hole of induced drafting does not cover by the paper, because the air exhauster flow is greater than the air input of the hole of induced drafting for the downthehole air of induced drafting of paper lower part becomes more rarefied, forms the negative pressure, makes the paper adsorb to fix on table surface with the pressure differential that produces above and below the paper. In the process of the spray gun working, the paper can be reliably adsorbed and fixed, and the spraying deacidification working quality is ensured.
