Description

Technical Field

[0001] This utility model relates to the field of pickling tank technology, specifically to a pickling tank for hot-dip galvanizing. Background Technology

[0002] Hot-dip galvanizing involves first pickling the iron workpiece to remove iron oxide from its surface. After pickling, the workpiece is cleaned in an aqueous solution of ammonium chloride or zinc chloride, or a mixture of both, before being immersed in a hot-dip galvanizing bath. Hot-dip galvanizing offers advantages such as uniform coating, strong adhesion, and long service life.

[0003] Chinese patent CN217517030U discloses a pickling tank for hot-dip galvanizing processes with good demisting effect. The tank includes a base, with the pickling tank body fixedly connected to the top of the base. One end of the pickling tank body has a discharge port, and a sealing cover is fixedly connected to the top of the pickling tank body. This application utilizes the coordinated arrangement of the discharge port, sealing cover, bend pipe, motor, and fan blades. The sealing cover is fixedly connected to the top of the pickling tank body, and the bend pipe passes through the sealing cover and communicates with the inner cavity of the pickling tank body. When the user turns on the motor, negative pressure is applied to discharge the acid mist inside the pickling tank body through the bend pipe. Simultaneously, negative pressure is generated inside the pickling tank body, allowing outside air to enter through the discharge port and seal it, preventing acid mist from escaping. This minimizes the problem of acid mist generated inside the pickling tank body diffusing into the surrounding environment and harming the health of workers.

[0004] However, it still has the following drawbacks: the device controls the extension of the hydraulic cylinder to move the iron workpiece to the right for discharge, but during the pickling process, the concentration of the pickling solution changes locally, and the device does not agitate the pickling solution, affecting the pickling effect. Therefore, we propose a pickling tank for hot-dip galvanizing to solve this problem. Utility Model Content

[0005] The purpose of this utility model is to provide an pickling tank for hot-dip galvanizing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pickling tank for hot-dip galvanizing, comprising a pickling tank, wherein a hydrochloric acid concentration detection component is provided on the pickling tank, and a pickling device is provided on the outside of the pickling tank, wherein the pickling device includes a pickling section;

[0007] The pickling section includes a cover plate, a fixing block, a hydraulic rod, a motor, and a drive plate. The bottom surface of the hydraulic rod is fixedly connected to the top surface of the fixing block, the top surface of the motor is fixedly connected to the bottom surface of the pickling tank, and the outer surface of the top end of the motor output rod rotates through the bottom surface of the pickling tank and extends into the interior of the pickling tank through a sealed bearing. The drive plate is fixedly sleeved on the outer surface of the motor output shaft.

[0008] The pickling tank is equipped with a positioning part inside;

[0009] The positioning part includes a T-shaped slide rod, a connecting rod, a placement plate, and a connecting plate. The bottom surface of the connecting rod is fixedly connected to the top surface of the placement plate, and the back surface of the connecting plate is fixedly connected to the front surface of the T-shaped slide rod.

[0011] A further improvement is that the sleeve is fitted on the outside of the drive plate, the fixing plate is fixedly fitted on the outer surface of the sleeve, and the front and rear end faces of the fixing plate are fixedly connected to the inner wall of the pickling tank. By setting the fixing plate, sleeve, motor and drive plate, it is convenient to drive the pickling liquid to circulate.

[0012] A further improvement is that the top surface of the cover plate has a through hole, and the bottom surface of the suction pipe is fixedly connected to the top surface of the cover plate. By setting the suction pipe, it is convenient to absorb the harmful gases generated during the pickling of iron workpieces.

[0013] A further improvement is that a T-shaped through groove is formed on the outer surface of the cover plate, the outer surface of the rear end of the T-shaped slide rod extends into the interior of the T-shaped slide groove and slides in connection with the inner wall of the T-shaped slide groove, and the top surface of the connecting rod is fixedly connected to the bottom surface of the T-shaped slide rod. By setting up the T-shaped slide rod, the connecting plate, the connecting rod and the placement plate, the placement plate moves forward when the cover plate is opened, which facilitates the picking up and placing of iron workpieces.

[0014] A further improvement is that the positioning part also includes a positioning bolt and a limiting plate. The outer surface of the rear end of the positioning bolt is threaded through the front of the connecting plate and the front of the cover plate and extends into the inside of the cover plate. By setting the positioning bolt, it is convenient to position the placement plate.

[0015] A further improvement is that a groove is provided on the top surface of the T-shaped slide rod, the outer surface of the limiting plate is slidably connected to the inner wall of the T-shaped slide rod, and the top surface of the limiting plate is fixedly connected to the inner wall of the cover plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This pickling tank for hot-dip galvanizing processing, by setting up a fixed block, hydraulic rod, motor, suction pipe, drive plate, sleeve, fixed plate and cover plate, can control the up and down movement of the cover plate by controlling the extension of the hydraulic rod. The workpiece to be pickled is placed inside the pickling tank, and the iron workpiece can be pickled. The sleeve and fixed plate guide the pickling solution inside the pickling tank. Starting the motor makes the drive plate rotate, so that the pickling solution circulates inside the pickling tank, so that the pickling solution inside the pickling tank is pickled. A more uniform solution concentration is beneficial for improving the pickling speed and effect of iron workpieces. By setting up a T-shaped slide bar, connecting rod, placement plate, and connecting plate, the iron workpiece is placed on the placement plate, suspending it in the pickling tank. By pulling the connecting plate, the placement plate can be moved back and forth, making it easy to pick up and place the iron workpiece. By setting up positioning bolts and limiting plates, the connecting plate is positioned by rotating the positioning bolts, keeping the placement plate stable. The limiting plate limits the T-shaped slide bar, preventing it from being pulled out completely from the cover plate. Attached Figure Description

[0027] The outer surface of the fixing block 321 is fixedly connected to the outer surface of the pickling tank 1, and the top surface of the hydraulic rod 322 output rod is fixedly connected to the bottom surface of the cover plate 328. By setting the fixing block 321, hydraulic rod 322, motor 323, suction pipe 324, drive plate 325, sleeve 326, fixing plate 327 and cover plate 328, the cover plate 328 can be moved up and down by controlling the extension of the hydraulic rod 322. The workpiece to be pickled is placed inside the pickling tank 1, and the iron workpiece can be pickled. The sleeve 326 and fixing plate 327 are used to guide the pickling solution inside the pickling tank 1. The motor 323 is started to make the drive plate 325 rotate, so that the pickling solution circulates inside the pickling tank 1, making the concentration of the pickling solution inside the pickling tank 1 more uniform, which is conducive to improving the pickling speed and pickling effect of the iron workpiece.

[0028] The pickling tank 1 is equipped with a positioning part 31;

[0029] The positioning part 31 includes a T-shaped slide bar 311, a connecting rod 312, a placement plate 313 and a connecting plate 314.
