Description

Technical Field

[0001] This utility model relates to the field of acid treatment technology for galvanized steel pipes, specifically to an acid treatment device for galvanized steel pipes that prevents splashing. Background Technology

[0002] Galvanized steel pipe is a type of welded steel pipe with a hot-dip or electro-galvanized layer on its surface. To improve the corrosion resistance of steel pipes, ordinary steel pipes are galvanized. Ungalvanized pipes are called black iron pipes, while galvanized pipes are called white iron pipes. Galvanized steel pipes are divided into two types: cold-galvanized steel pipes and hot-dip galvanized steel pipes. Cold-galvanized steel pipes have been banned, while hot-dip galvanized steel pipes are widely used.

[0003] A search revealed a device for acid treatment of galvanized steel pipes, publication number (CN211570780U). The device includes a housing with a cover plate movably connected to the top. An observation port is provided on the upper surface of the cover plate. Two rollers are fixedly connected inside the housing. A central shaft is movably connected to one side of each roller. A square frame is movably connected between the two central shafts. A storage rod and a telescopic rod are movably connected between the two rollers. This device uses the sliding of the extension rod within a groove to change the tension of a spring. It utilizes a change in magnetic field to collect undigested rust and other substances from hydrochloric acid. The rollers drive the steel pipe to rotate, repeatedly reacting in the hydrochloric acid and then polishing the surface under the cover plate. Polishing can be performed directly during the reaction with hydrochloric acid, saving hydrochloric acid and more conveniently removing rust from the steel pipe surface. However, this structure cannot prevent acidic liquids from splashing out, which could easily cause harm to the human body. Therefore, a new structure is proposed to solve this technical problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an acid treatment device for galvanized steel pipes that prevents splashing, which has advantages such as preventing splashing and solves the problem mentioned in the background art that traditional devices cannot prevent acidic liquids from splashing out during use.

[0005] To achieve the purpose of preventing acidic liquid splashing mentioned in the background art, this utility model provides the following technical solution: an acid treatment device for anti-splashing galvanized steel pipe, comprising a base, a bottom tank disposed on one side of the outer surface of the base, an acidification tank disposed inside the bottom tank, a device tube disposed inside the bottom tank, a mesh plate disposed on one side of the inner wall of the device tube, a bent pipe disposed on one side of the outer surface of the device tube, a threaded plate disposed on one side of the inner wall of the bottom tank, a cover plate disposed on one side of the outer surface of the bottom tank, a threaded rod disposed on one side of the outer surface of the cover plate, an auxiliary tube disposed on one side of the outer surface of the cover plate, a pull rod disposed inside the auxiliary tube, a placement groove disposed at one end of the pull rod, a spring disposed on the upper side of the inner wall of the placement groove, a clamping plate disposed at one end of the spring, a support rod disposed on one side of the outer surface of the clamping plate, and a device hole disposed on one side of the outer surface of the placement groove.

[0008] Preferably, one end of the bent pipe contacts one side of the outer surface of the device tube, penetrates one side of the outer surface of the device tube, extends into the device tube, and is fixedly connected to the device tube.

[0009] Preferably, there are two threaded plates, and the two threaded plates are evenly arranged on the left and right sides of the inner wall of the bottom tank.

[0010] Preferably, one side of the outer surface of the threaded plate contacts one side of the inner wall of the bottom tank, penetrates one side of the inner wall of the bottom tank, extends to one side of the outer surface of the bottom tank, and is fixedly connected to the bottom tank.

[0011] A threaded hole is provided on one side of the outer surface of the threaded plate, and one end of the threaded hole contacts one side of the outer surface of the threaded plate and penetrates one side of the outer surface of the threaded plate to the other side of the outer surface of the threaded plate. The threaded hole is adapted to the threaded rod, so that when the threaded rod and the threaded hole are threadedly connected, the cover plate is connected to the bottom tank. When the threaded rod is disengaged from the threaded plate, the cover plate can be removed, thus achieving the effect of easy disassembly and assembly.

[0012] Furthermore, the auxiliary tube has upper and lower sliding grooves on both sides of its inner wall. One side of the outer surface of the upper and lower sliding grooves contacts one side of the inner wall of the auxiliary tube and penetrates one side of the inner wall of the auxiliary tube into the auxiliary tube. The pull rod penetrates the auxiliary tube, and sliding rods are provided on both sides of the outer surface of the pull rod. One end of the sliding rod is fixedly connected to one side of the outer surface of the pull rod, and the other end of the sliding rod is slidably connected to the inner wall of the upper and lower sliding grooves. This allows the pull rod to move only up and down and makes it more stable.

[0013] Furthermore, the clamp is set in the placement groove, and the left and right ends of the clamp are inclined, so that when the galvanized steel pipe is placed in the placement groove, the galvanized steel pipe is squeezed against the clamp, which makes it easier to place.

[0014] Compared with the prior art, this utility model provides an acid treatment device for splash-proof galvanized steel pipes, which has the following beneficial effects:

[0015] 1. This utility model uses a mesh plate installed inside the device, which runs through the device tube and the acidification tank. When the galvanized steel pipe to be processed is placed in the placement trough and then covered with a cover plate, the acidic liquid is squeezed out of the mesh plate and flows into the device tube when the galvanized steel pipe enters the acidification tank. It then flows out through the bend pipe, thus preventing splashing.

[0016] 2. In this utility model, by setting a placement groove in the device and setting a clamping plate in the placement groove, and connecting the clamping plate and the placement groove by a spring, the steel pipes of different specifications placed in the placement groove will be squeezed and fixed, increasing the flexibility of use.
