Water flow and waste residues can smoothly enter the center position of the limiting barrel through the water passing hole formed in the limiting barrel, the water flow speed can be effectively reduced, the grab bucket cannot be separated from the limiting barrel after extending into the center barrel, and therefore the grab bucket is prevented from being clamped on channel steel at the bottom of the rotational flow well body.

Description

Technical Field

[0001] This utility model relates to the field of steel smelting equipment, and in particular to a vortex well. Background Technology

[0002] Steel companies typically use cyclone wells to treat solid waste such as iron oxide scale generated during steel rolling. The iron oxide scale enters the cyclone well with the turbid circulating water, settles inside, and is then grabbed by a grab bucket and transported away. A traditional cyclone well structure, as described in Chinese Patent Application No. 201520396281.7, includes a well body with a central cylinder inside, which is supported by a support column on top of a slag hopper. In actual production, due to the large water drop and high flow velocity within the cyclone well, the high-speed rotation of the grab bucket during slag removal causes severe twisting of the grab bucket's wire rope, resulting in frequent damage. Furthermore, the grab bucket may become stuck on the support column (usually a channel steel). If stuck, it will be quickly buried by the slag in the cyclone well, making it extremely difficult to remove. Therefore, a redesign of the internal space of the cyclone well is necessary. Utility Model Content

[0003] The purpose of this invention is to provide a vortex well.

[0004] The technical solution to achieve the purpose of this utility model is as follows: a vortex well, comprising a vortex well body, a central cylinder vertically disposed at the center of the vortex well body, the central cylinder being fixedly supported by channel steel fixed to the vortex well body; a grab bucket limiting assembly is installed between the bottom of the central cylinder and the bottom of the vortex well body, the grab bucket limiting assembly comprising a limiting cylinder having a limiting cylinder top end and a limiting cylinder bottom end, both the limiting cylinder top end and the limiting cylinder bottom end being open, the limiting cylinder having several water passage holes on its cylinder wall, the limiting cylinder being nested inside the bottom of the central cylinder and fixed to the central cylinder, the limiting cylinder bottom end extending from the bottom of the central cylinder; the limiting cylinder being fixedly supported by a support frame fixed to the bottom of the vortex well body, the support frame being disposed below the bottom end of the limiting cylinder and arranged circumferentially along the edge of the bottom end of the limiting cylinder, the height of the support frame being less than the height of the grab bucket clamp.

[0005] Furthermore, two reinforcing ribs are installed on the inner side of the bottom end of the limiting cylinder. The two reinforcing ribs are arranged in a cross shape, and both ends of the reinforcing ribs are fixed to the inner wall of the limiting cylinder.

[0006] The vortex well implemented in this utility model has a grab bucket limiting component set on one side of the bottom of the vortex well body. The limiting cylinder of the grab bucket limiting component has a water passage hole, which allows water and waste to smoothly enter the center position of the limiting cylinder and can effectively slow down the water flow rate. The support frame is used to ensure that the entire grab bucket limiting component is firmly fixed inside the vortex well. The height of the support frame is less than the height of the grab bucket clamp. After the grab bucket is extended into the central cylinder, it will not detach from the limiting cylinder, thereby preventing the grab bucket from getting stuck on the channel steel at the bottom of the vortex well body.

[0010] The specific embodiments of the vortex well of this utility model are described in detail below with reference to the accompanying drawings:

[0011] like Figure 1 and Figure 2 As shown, a vortex well includes a vortex well body 1, a central cylinder 2 vertically disposed at the center of the vortex well body 1, and the central cylinder 2 being fixedly supported by a channel steel 3 fixed to the vortex well body 1; a grab bucket limiting assembly 4 is installed between the bottom 21 of the central cylinder 2 and the bottom 11 of the vortex well body 1, the grab bucket limiting assembly 4 including a limiting cylinder 41, the limiting cylinder 41 having a limiting cylinder top end 411 and a limiting cylinder bottom end 412, both the limiting cylinder top end 411 and the limiting cylinder bottom end 412 being open, the cylinder wall of the limiting cylinder 41 having several water passage holes 413, and two reinforcing ribs 414 being installed on the inner side of the limiting cylinder bottom end 412, the two reinforcing ribs 414 being arranged in a cross shape, and both ends of the reinforcing ribs 414 being fixed to the inner wall of the limiting cylinder 41 respectively.

[0012] The limiting cylinder 41 is nested inside the bottom 21 of the central cylinder 2 and fixed to the central cylinder 2. The bottom end 41 of the limiting cylinder extends out from the bottom 21 of the central cylinder 2. The limiting cylinder 41 is fixedly supported by a support frame 42 fixed to the bottom of the vortex well body 1. The support frame 42 is located below the bottom end 412 of the limiting cylinder and is arranged circumferentially along the edge of the bottom end 412 of the limiting cylinder. The height of the support frame 42 is less than the height of the clamp of the grab bucket (not shown).

[0013] During operation, the grab bucket extends from the central cylinder 2 and through the limiting cylinder 41 into the bottom 11 of the vortex well body 1 to perform sediment grabbing operations. Since the height of the support frame 42 is less than the height of the grab bucket's clamps, the range of motion of the grab bucket's clamps is limited within the limiting cylinder 41, thereby preventing the clamps from coming out of the limiting cylinder 41 and getting stuck on the channel steel 3.

[0014] The number and size of the water passage holes in this invention can be set as needed. The water passage holes allow water and waste residue to smoothly enter the center of the limiting cylinder and effectively slow down the water flow rate. The number of the support frames is also unlimited, as long as they can provide effective support for the limiting cylinder. The reinforcing ribs can be set as needed, and adding reinforcing ribs can improve the strength of the limiting cylinder.

[0015] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent process transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
