Description

Technical Field

[0001] The utility model relates to the field of color steel production, in particular to a zinc liquid extraction device. Background Art

[0002] In hot-dip galvanizing production, when the zinc pot needs to be repaired, the inductor needs to be replaced, or the type of product needs to be changed, nearly 100 tons of zinc liquid must be taken out. Usually, a special zinc pump is required to extract the zinc liquid into the zinc storage tank. Using a zinc pump to extract zinc is a special operation. The zinc pump works in a high temperature environment of 300-600℃, which has high requirements for the material, corrosion resistance, safety and stability of the zinc pump and the operating skills of the operator. During the zinc extraction operation, the upper bearing of the zinc pump is often stuck due to the increase in temperature, and the lower part is often blocked due to the suction of bottom slag. The shaft or impeller part immersed in the zinc pot zinc liquid should also prevent the temperature difference from being too large to prevent deformation. Attention must be paid to all details to successfully complete the operation. After the zinc pump operation is completed, it must be placed in an acid tank to pickle the zinc slag, and the bearing, motor and other parts must be maintained before they can be used later. Therefore, the conventional liquid extraction method is not only a live operation, there is a risk of electric shock, poor safety, but also has a high comprehensive cost. Utility Model Content

DETAILED DESCRIPTION

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0023] Embodiment 1

[0024] like Figure 1-4 As shown, the utility model discloses a device for extracting zinc liquid from a zinc pot, which includes a box 1 for containing zinc liquid and a series of structures arranged in the box for opening and closing the zinc liquid inlet inside the box. A flat steel X-shaped suspension 14 is installed around the upper end of the box to lift and transfer the box and the zinc liquid in the box. The box is enclosed and welded by 4 steel plates (size is 900×700×870×15mm), and then welded with a bottom steel plate (upper×lower×height×thickness: 700×700×900×15mm) to form a square bucket. A circular zinc liquid inlet (diameter 40-80mm) is left in the center of the bottom steel plate for the zinc liquid to enter and exit. A sealing plug 8 is arranged above the liquid inlet, and the upper end of the sealing plug is connected to the lifting rod 2. The upper end of the main square bucket is open, and a crossbeam 13 is welded at its horizontal center. The crossbeam is a U-shaped channel steel (width × height × thickness: 80 × 40 × 4mm). The end surface of the channel steel faces upward, serving as the support surface for operating the lifting rod 2 and the driving lever 5. A sleeve 15 is welded to the center hole of the support surface. The lifting rod 2 passes through the sleeve upward and is hinged to the first hinge seat 3 at the left end of the driving lever 5 (length 650mm DN25 galvanized pipe). A support seat 16 (height h = 100mm) is welded at 110mm from the center of the surface, and the second hinge seat 4 on the driving lever 5 is hinged to the support seat. Each hinge seat is connected with a metal pin. By operating the driving lever rod to lift and press up and down, the lifting rod 2 can move up and down along the sleeve 15 (diameter × height: Ф27mm × 20mm), and the sealing plug at the lower end of the lifting rod opens or closes the zinc liquid inlet. The driving lever 5 drives the lifting rod 2 to move up and down within a range of 50 mm. The upper and lower ends within the range of movement are temporarily positioned by a rotating seat 6 and two positioning rods of different heights installed on the rotating seat.

[0025] The support shaft 9 is welded on the upper end of the right wall of the box body, the rotating sleeve 6-1 of the rotating seat 6 is sleeved on the outside of the support shaft 9, and the base 6-2 is welded on the lower end of the rotating sleeve. The base is a steel plate with a hole in the center (height×width×thickness: 150×150×15mm). The rotating sleeve is welded above the center hole, and the base can rotate with the rotation of the rotating sleeve. The upper positioning rod 10 is welded on the side of the upper end of the rotating sleeve, and the lower positioning rod 11 is welded below the upper positioning rod and on the other side of the rotating sleeve. The positioning seat 12 is welded on the side wall of the box body. When it is necessary to open the zinc liquid inlet to allow the zinc liquid to enter the box body 1 from the bottom of the box body, the rotating sleeve 6-1 is screwed to the position where the upper positioning rod 10 and the lower positioning rod 11 are parallel to the driving lever 5, and the end of the driving lever 5 is pressed. The driving lever 5 rotates with the second hinge seat 4 as the fulcrum, and the driving lever 5 drives the first hinge seat 3 to rise, thereby driving the lifting rod 2 to rise, and the sealing plug 8 at the bottom of the lifting rod rises, the zinc liquid inlet is opened, and the zinc liquid in the zinc pot flows in through it. At this time, the rotating sleeve 6-1 is rotated until the upper positioning rod 10 is located above the driving lever 5. Figure 2-3 As shown, the upper positioning rod 10 presses the driving lever 5, and the positioning seat 12 is fixed to the base 6-2 by the positioning pin 7, and the zinc liquid inlet is always in an open state.

[0026] When the zinc liquid rises to a certain height in the box, the rotating sleeve 6-1 is screwed again to the position where the upper positioning rod 10 and the lower positioning rod 11 are parallel to the driving lever 5, the end of the driving lever 5 is lifted, and the other end is lowered accordingly. The lifting rod 2 is lowered to drive the sealing plug 8 to descend. The sealing plug is made of elastic material. The lifting rod is lowered to press and deform the sealing plug to seal the zinc liquid inlet, and then the rotating sleeve 6-1 is screwed to the position where the lower positioning rod 11 is located below the driving lever 5. Figure 4 As shown, the positioning seat 12 is fixed to the hole at the other end of the base 6-2 by a positioning pin 7 to prevent the end of the driving lever 5 from being pressed down and causing leakage.

[0027] A suspension consisting of two intersecting square steels (20×20mm, length 2200mm) is welded at a height of 800mm at the center of the upper opening of the box for easy lifting. A professional lifting machinery hook is connected to this hanging position to assist in the operation of taking and placing the zinc pot and zinc liquid.

[0028] Embodiment 2

[0029] In this embodiment, the sealing plug 8 is as follows Figure 5 The stepped shaft structure shown includes a covering section 8-1 with a larger diameter at the top and an inserting section 8-2 with a smaller diameter at the bottom. When the sealing plug is used to block the zinc liquid inlet, the inserting section is inserted into the zinc liquid inlet, and the covering section covers the upper end of the zinc liquid inlet to achieve blocking.

[0030] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
