Abstract

A water inlet end connecting structure of a high-pressure spray header assembly of a metal strip foil cleaning line is used for high-pressure spray cleaning of metal foils. Comprising a high-pressure spraying header, a connecting flange and a water inlet connector, and the high-pressure spraying header penetrates through a through hole of the connecting flange, extends to the outer end of the connecting flange and forms a movable connecting structure with the connecting flange; the water inlet connector is fixedly arranged at the outer end of the high-pressure spraying header, high-pressure spraying liquid directly enters the high-pressure spraying header through the water inlet connector, and therefore after high-pressure water enters the high-pressure spraying header, the acting force for pushing the connecting flange cannot be generated, and the problem that when an existing metal strip foil cleaning line works, the working efficiency is high is solved. The problem that the wall plate of the box body deforms due to the movement of the connecting flange is solved, so that spraying liquid leakage caused by the deformation of the wall plate of the box body is avoided, and the technical effects of improving the environment of a production field and avoiding adverse effects on the body health of workers on the production field are achieved.

The existing problem of the connection structure between the high-pressure spray header and the box wall panel of the metal strip and foil cleaning line is that: since the water inlet end of the high-pressure spray header is floatingly connected to the connecting flange, and the high-pressure water enters the high-pressure spray header through the connecting flange, when the high-pressure water enters the high-pressure spray header, it will push the connecting flange to move, thereby causing the box wall panel fixed with the connecting flange to deform; and the box wall panel is equipped with a number of sealing structures of working rollers (the working roller support bearings are fixedly arranged on the outer frame structure of the box). When the box wall panel is deformed, it will affect the sealing performance of the working roller sealing structure, causing the spray liquid in the box to leak from the working roller sealing structure, thereby polluting the production site environment; in addition, some spray liquids are acidic or alkaline, so the leaked spray liquid will also have an adverse effect on the health of the production site workers.

[0016] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0017] See the instruction manual Figure 1 : It shows the water inlet end connection structure of the existing metal strip foil cleaning line high-pressure spray header assembly, which includes a high-pressure spray header 1, a header water inlet end 2, a connecting flange 3, and a plug A4. A through hole is provided in the middle of the connecting flange 3, a flange end cavity 3.1 is provided at the right end of the through hole, a flange water inlet 3.2 is provided on the left side wall of the through hole, and a flange water inlet joint 11 is fixedly provided at the flange water inlet 3.2; the header water inlet end 2 is fixedly connected to the left end of the high-pressure spray header 1, the header water inlet end 2 is movably arranged in the flange end cavity 3.1, and a gap is provided between the outer end surface 2.1 of the header water inlet end 2 and the bottom of the flange end cavity 3.1, and the gap is used to compensate for the length change of the high-pressure spray header 1 (such as the temperature change of the production workshop, the spray liquid in the high-pressure spray header 1 is at a high temperature, which will cause the length of the high-pressure spray header 1 to change), and the plug A4 is fixedly arranged at the left end of the through hole of the connecting flange 3;

[0018] When high-pressure water (6.5MPa) enters the high-pressure spray manifold 1 from the flange water inlet 3.2, it will enter the gap between the outer end face 2.1 of the manifold water inlet end 2 and the bottom of the flange end cavity 3.1, thereby generating a leftward thrust at the bottom of the flange end cavity 3.1, pushing the connecting flange 3 to move to the left, thereby causing the box wall panel 5 that fixes the connecting flange 3 to deform (in fact, the box wall panel 5 at the drain outlet end of the high-pressure spray manifold 1 will also deform). When the box wall panel is deformed, it will affect the sealing performance of the working roller sealing structure, causing the spray liquid in the box to leak from the working roller sealing structure, thereby polluting the production site environment.

[0019] Example 1, see the attached specification Figure 2 :

[0020] A water inlet end connection structure of a high-pressure spray header assembly of a metal strip foil cleaning line comprises a high-pressure spray header 1, a connecting flange 3, and a water inlet joint 9; a through hole is provided in the connecting flange 3, and is fixedly connected to a box wall plate 5; the high-pressure spray header 1 passes through the through hole of the connecting flange 3, extends to the outer end of the connecting flange 3, and is movably connected to the connecting flange 3, and is used to compensate for the length change of the high-pressure spray header 1; two sealing rings are provided between the high-pressure spray header 1 and the connecting flange 3 to prevent leakage of spray liquid in the box; the water inlet joint 9 is fixedly provided at the outer end of the high-pressure spray header 1, and the high-pressure spray liquid enters the high-pressure spray header 1 through the water inlet joint 9;

[0021] When the metal strip and foil cleaning line is working, the high-pressure spray liquid directly enters the high-pressure spray header 1 through the water inlet joint 9. Therefore, after the high-pressure water enters the high-pressure spray header 1, it will not generate a force to push the connecting flange 3, thereby solving the problem of deformation of the box wall panel when the existing metal strip and foil cleaning line is working, and then avoiding the leakage of spray liquid caused by the deformation of the box wall panel, thereby achieving the technical effect of improving the production site environment and avoiding adverse effects on the health of production site workers.

[0022] Example 2, see the attached specification Figure 3 :

[0023] In this embodiment, a reducer 6 and a water inlet pipe 8 are added; the water inlet end of the high-pressure spray header 1 is welded to the water inlet pipe 8 through the reducer 6, the water inlet pipe 8 passes through the through hole of the connecting flange 3, extends to the outer end of the connecting flange 3, and is movably connected to the connecting flange 3, and two sealing rings are arranged between the water inlet pipe 8 and the connecting flange 3; the water inlet joint 9 is fixedly arranged at the outer end of the water inlet pipe 8;

[0024] In this embodiment, the diameter of the connecting flange 3 is reduced by the reducer 6 and the water inlet pipe 8, thereby reducing the diameter of the connecting flange 3 and reducing the cost of the connecting flange 3.

[0025] Example 3, see the attached specification Figure 4 :

[0026] This embodiment is a modification scheme based on the existing water inlet connection structure of the high-pressure spray header assembly of the metal strip foil cleaning line, and can be used to modify the water inlet connection structure of the high-pressure spray header assembly of the existing metal strip foil cleaning line; in this embodiment, based on the existing water inlet connection structure of the high-pressure spray header assembly of the metal strip foil cleaning line, a reducer 6, a water inlet pipe 8, and a water inlet joint 9 are added, the header water inlet end 2 is cancelled, and a through hole is processed in the plug A4 to transform it into a plug B7;

[0027] The water inlet end of the high-pressure spray header 1 is welded and connected to the water inlet pipe 8 through a reducer 6, and the plug B7 is fixedly arranged at the outer end of the connecting flange 3; the water inlet pipe 8 passes through the through holes of the connecting flange 3 and the plug B7, extends to the outer end of the plug B7, and is movably connected with the connecting flange 3 and the plug B7, and two sealing rings are arranged between the water inlet pipe 8 and the connecting flange 3 and the plug B7; the water inlet joint 9 is fixedly arranged at the outer end of the water inlet pipe 8, and the flange water inlet 3.2 of the original connecting flange 3 is fixedly provided with a drainage joint 10 (which is the flange water inlet joint 11 of the existing metal strip foil cleaning line high-pressure spray header assembly), and the drainage joint 10 is connected back to the box of the metal strip foil cleaning line through a pipeline;

[0028] When the water inlet connection structure of the existing metal strip and foil cleaning line high-pressure spray header assembly is modified, because the through hole of the connecting flange 3 is a water hole, its surface roughness is relatively high. During long-term operation, the two sealing rings between the water inlet pipe 8 and the connecting flange 3 will wear due to compensation for the length change of the high-pressure spray header 1, and thus leakage is prone to occur; when the two sealing rings between the water inlet pipe 8 and the connecting flange 3 leak, the leaked spray liquid returns to the box of the metal strip and foil cleaning line through the drainage joint 10, avoiding pollution to the production site environment.

[0029] Example 4, see the attached specification Figure 5 :

[0030] This embodiment is a further optimization based on the third embodiment. This embodiment cancels the plug B7 in the third embodiment, and simplifies the flange end cavity 3.1 of the connecting flange 3. A drainage ring groove is set in the through hole of the connecting flange 3, and a threaded hole is set at the bottom of the drainage ring groove. The drainage joint 10 is fixed in the threaded hole and connected to the drainage ring groove.

[0031] The various technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the various technical features in the above-described embodiments are described. However, it should be understood that the present utility model is intended to protect all changes and improvements of all embodiments within the scope of the present concept and utility model.

[0032] The parts not described in detail in this utility model are prior art.
