Description

Technical Field

[0001] This application relates to the technical field of stainless steel wire rods, and particularly to a pickling and passivation device for the production of stainless steel wire rods. Background Art

[0002] A stainless steel wire rod is a round steel coiled, and its commercial form is usually supplied in coils. Among the wire rods commonly seen on construction sites, most are low-carbon steel, generally not used as the main reinforcement bars in reinforced concrete structures, but mostly used for making steel bar sleeves, and small-diameter ones are used for brick reinforcement in brick-concrete structures.

[0003] During the production process of stainless steel wire rods, pickling and passivation treatment is required. However, currently, during the pickling and passivation treatment of stainless steel wire rods, it is not convenient to take out the stainless steel wire rods from the pickling and passivation device. For this reason, we propose a pickling and passivation device for the production of stainless steel wire rods to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a pickling and passivation device for the production of stainless steel wire rods to solve the problems raised in the above background art.

[0005] The embodiments of this application adopt the following technical solutions:

[0006] A pickling and passivation device for the production of stainless steel wire rods includes a pickling and passivation tank. Both the left side and the right side of the pickling and passivation tank are fixedly installed with two fixing blocks. The upper surface of each fixing block is fixedly installed with an electric hydraulic push rod. The output end of each group of electric hydraulic push rods is fixedly installed with a special-shaped plate. The bottom surface of each special-shaped plate is fixedly installed with a connecting column. The bottom end of each connecting column extends into the interior of the pickling and passivation tank. The bottom surfaces of the four connecting columns are jointly fixedly installed with a placement plate.

[0007] Preferably, a number of equally spaced strip-shaped liquid leakage openings are formed on the upper surface of the placement plate. Two longitudinal enclosures and two transverse enclosures are fixedly installed on the upper surface of the placement plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] To make the objectives, technical solutions and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the described embodiments are only a part rather than all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0023] The following will, with reference to the drawings, elaborate on the technical solutions provided by each embodiment of this application.

[0024] Please refer to Figures 1-4 , the present utility model provides a pickling and passivation device technical solution for the production of stainless steel wire rods:

[0025] A pickling and passivation device for the production of stainless steel wire rods includes a pickling and passivation tank 8. Two fixing blocks 9 are fixedly installed on each of the left side and the right side of the pickling and passivation tank 8. An electric hydraulic push rod 7 is fixedly installed on the upper surface of each fixing block 9. The output end of each group of electric hydraulic push rods 7 is fixedly installed with a special-shaped plate 5. A connecting column 6 is fixedly installed on the bottom surface of each special-shaped plate 5. The bottom end of each connecting column 6 extends into the pickling and passivation tank 8. The bottom surfaces of the four connecting columns 6 are commonly fixedly installed with a placement plate 16; specifically, pickling agent can be stored inside the pickling and passivation tank 8, and the pickling agent can be used for pickling and passivating the stainless steel wire rods. The four fixing blocks 9 respectively support the four electric hydraulic push rods 7. Every two electric hydraulic push rods 7 form a group, which jointly lift the special-shaped plate 5. The four connecting columns 6 jointly connect the placement plate 16 and the two special-shaped plates 5. When the output ends of the four electric hydraulic push rods 7 rise and fall together, the placement plate 16 can be driven to rise and fall through the two special-shaped plates 5 and the four connecting columns 6. Multiple stainless steel wire rods can be placed on the upper surface of the placement plate 16. After the pickling and passivation treatment of the stainless steel wire rods, the worker controls the placement plate 16 to rise, and the stainless steel wire rods can be quickly removed.

[0026] In this embodiment, a plurality of strip-shaped liquid leakage openings 15 arranged at equal distances are formed on the upper surface of the placing plate 16. Two longitudinal enclosures 17 are fixedly installed on the upper surface of the placing plate 16, and two transverse enclosures 18 are fixedly installed on the upper surface of the placing plate 16. A discharge pipe 13 is fixedly communicated with the right side surface of the pickling and passivation tank 8, and a solenoid valve 12 is fixedly installed on the outer surface of the discharge pipe 13. A control box 4 is fixedly installed on the front surface of the pickling and passivation tank 8. A controller 14 is fixedly installed on the inner wall of the control box 4. Each electric hydraulic push rod 7 is electrically connected to the controller 14 through a wire. Specifically, by forming a plurality of strip-shaped liquid leakage openings 15 arranged at equal distances on the upper surface of the stainless steel wire rod, when the placing plate 16 descends, the pickling agent can quickly surge above the placing plate 16 through the plurality of strip-shaped liquid leakage openings 15 and cover the stainless steel wire rod. When the pickling and passivation treatment is completed and the placing plate 16 rises, the pickling agent can quickly drip into the pickling and passivation tank 8 through the plurality of strip-shaped liquid leakage openings 15. The two longitudinal enclosures 17 and the two transverse enclosures 18 jointly play a role in limiting the stainless steel wire rod placed on the upper surface of the placing plate 16. The pickling agent stored inside the pickling and passivation tank 8 can be quickly discharged to the outside of the pickling and passivation tank 8 through the discharge pipe 13. The staff can conveniently control the extension or contraction of the output ends of the four electric hydraulic push rods 7 through the controller 14.

[0027] In this embodiment, a plurality of strip-shaped heat dissipation openings 3 arranged at equal distances are formed on both the left side surface and the right side surface of the control box 4. The solenoid valve 12 is electrically connected to the controller 14 through a wire. A box door 1 is hinged to the inner wall of the control box 4 through a hinge, and a handle 2 is fixedly installed on the front surface of the box door 1. Four support legs 10 are fixedly installed on the bottom surface of the pickling and passivation tank 8, and a support base 11 is fixedly installed on the bottom surface of each support leg 10. Specifically, by forming a plurality of strip-shaped heat dissipation openings 3 arranged at equal distances on both the left side surface and the right side surface of the control box 4, air can freely circulate inside the control box 4, so that the controller 14 inside the control box 4 can be quickly cooled and dissipated. By electrically connecting the solenoid valve 12 to the controller 14 through a wire, the staff can conveniently open or close the solenoid valve 12 through the controller 14. By hinging the box door 1 to the control box 4 through a hinge and installing a handle 2 on the front surface of the box door 1, the staff can conveniently open the box door 1 through the handle 2. By installing four support legs 10 on the bottom surface of the pickling and passivation tank 8, the four support legs 10 can jointly lift the pickling and passivation tank 8 to a certain height. By installing a support base 11 on the bottom surface of each support leg 10, the contact area between the device and the ground can be effectively increased, so that the device can be stably placed.

[0028] Working principle: When the device is in use, the user first places the stainless steel wire rod above the placement plate 16. Subsequently, the staff controls the output ends of the four electro-hydraulic push rods 7 to contract simultaneously through the controller 14. The simultaneous contraction of the output ends of the four electro-hydraulic push rods 7 drives the two special-shaped plates 5, the four connecting columns 6, and the placement plate 16 to move downward, and finally immerses the stainless steel wire rod placed above the placement plate 16 in the pickling agent. When the pickling and passivation treatment of the stainless steel wire rod is completed, the staff controls the output ends of the four electro-hydraulic push rods 7 to extend simultaneously through the controller 14. The simultaneous extension of the output ends of the four electro-hydraulic push rods 7 drives the two special-shaped plates 5, the four connecting columns 6, and the placement plate 16 to move upward, and finally lifts the multiple stainless steel wire rods and the placement plate 16 above the pickling agent. Finally, the staff can remove the stainless steel wire rod from above the placement plate 16.

[0029] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
