Description

Technical Field

[0001] This utility model relates to the field of continuous casting technology, specifically a feeding device for the preparation of long stopper rods. Background Technology

[0002] The equipment used in the current preparation of long stopper rods, such as... Figure 1-3 As shown, the device includes a pocket-core assembly consisting of an outer pocket 11, a cap 2, and a core rod 3, as well as a lower pocket section 12, and a feeding assembly consisting of an inner cylinder 4 and a centering device 5. Because the long stopper rod is too long, the feeding process needs to be divided into two stages. The specific steps are as follows: First, place the lower pocket section 12 onto the core rod 3 and fix the feeding assembly consisting of the inner cylinder 4 and the centering device 5 onto the core rod 3 and the lower pocket section 12; add the main body material from the inner cylinder 4 until material rises in the inner cylinder 4, indicating that the lower part of the lower pocket section 12 is full; add a measured amount of slag line material from the gap between the inner cylinder 4 and the centering device 5, ensuring accurate measurement, and then cover it with the main body material until the entire lower pocket section 12 is filled, completing the process. Figure 2 The first feeding is shown; remove the feeding assembly, put the outer bag 11 onto the lower part 12 of the bag, and proceed as follows. Figure 3 The second feeding shown completes the remaining routine feeding. The above feeding method is complicated, labor-intensive, and inefficient. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the prior art by providing a feeding device for the preparation of long stopper rods.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A feeding device for preparing long stopper rods includes a bag, a cap, a core rod, an inner cylinder, and a centering device. The inner cylinder is characterized in that it is composed of a short-diameter cylinder, a connecting enlargement cylinder, and a slag line cylinder connected in sequence, and the annular cavity area between the outer wall of the slag line cylinder and the inner wall of the bag is the slag line material feeding area.

[0006] The inner cavity of the slag line cylinder is provided with inner cylinder positioning elements, and at least three inner cylinder positioning elements are distributed in a circumferential manner along the radial direction of the core rod.

[0007] The inner cavity of the slag line cylinder is equipped with a set of inner cylinder positioning components at both the top and bottom.

[0008] The rear end of the inner cylinder positioning component is fixed to the inner wall of the slag line cylinder, and the gap between the front end and the outer wall of the core rod does not exceed 0.2mm.

[0009] The inner cylinder positioning component is made of thin steel sheet of 1mm to 2mm.

[0010] The height of the inner cylinder positioning component along the axial direction of the mandrel is not less than ten times the thickness of the inner cylinder positioning component.

[0011] The top of the inner cylinder is provided with a protruding screw connector, which is used to connect the pneumatic mechanism. The pneumatic mechanism drives the inner cylinder to vibrate and rise through the screw connector, thus pulling the inner cylinder out of the pocket.

[0012] The screw connector is connected to the top of the inner cylinder via a pin, allowing the screw connector to rotate relative to the inner cylinder.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The feeding device of this utility model extends the length of the inner cylinder and is equipped with a slag line tube, combined with an integrated bag structure, thereby enabling the feeding process to be completed quickly and conveniently, improving efficiency, reducing labor intensity, and reducing the manufacturing cost of the bag.

[0023] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0024] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended meaning of inclusion and that other elements / components / etc. may exist in addition to the listed elements / components / etc.

[0025] like Figure 4-7 As shown: A feeding device for preparing long stopper rods includes a pocket 1, a cap 2, a core rod 3, an inner cylinder 4, and a centering device 5. The pocket 1, cap 2, and core rod 3 constitute a pocket-core rod assembly, and the pocket 1 is an integral structure without inner or outer parts. The inner cylinder 4 and the centering device 5 constitute a feeding assembly. The inner cylinder 4 is composed of a short-diameter cylinder 41, a connecting enlargement cylinder 42, and a slag line cylinder 43 connected in sequence. The annular cavity area between the outer wall of the slag line cylinder 43 and the inner wall of the pocket 1 is the slag line material feeding area.

[0026] like Figure 4-5 As shown: An inner cylinder positioning element 44 is provided within the inner cavity of the slag line cylinder 43. At least three inner cylinder positioning elements 44 are arranged circumferentially along the radial direction of the core rod 3. The rear end of the inner cylinder positioning element 44 is fixed to the inner wall of the slag line cylinder 43, and the gap between the front end and the outer wall of the core rod 3 does not exceed 0.2 mm. The inner cylinder positioning element 44 is made of a thin steel sheet of 1 mm to 2 mm, and the height of the inner cylinder positioning element 44 along the axial direction of the core rod 3 is not less than ten times its thickness. To enhance the centering effect during feeding, it is preferable to arrange a set of inner cylinder positioning elements 44 at the top and bottom of the inner cavity of the slag line cylinder 43. Figure 5 The diagram shows a single-layer arrangement of three inner cylinder positioning components 44; combined with Figure 4 Then there are two layers and two sets of six inner cylinder positioning parts 44; of course, more inner cylinder positioning parts 44 can be set when needed.

[0027] To facilitate the disassembly of the feeding assembly, a screw connector 45 protruding from the centering 5 is provided on the top of the inner cylinder 4. The screw connector 45 is used to thread a pneumatic mechanism, which drives the inner cylinder 4 to vibrate and rise through the screw connector 45, pulling the inner cylinder 4 out of the pocket 1. To facilitate feeding, the screw connector 45 is connected to the top of the inner cylinder 4 by a pin, allowing the screw connector 45 to rotate relative to the inner cylinder 4.

[0028] When using the feeding device for preparing long stopper rods provided by this utility model, such as Figure 6-7 As shown, the lower part of the feeding assembly is fixed to the core rod 3 by six inner cylinder positioning parts 44, the upper centering part 5, and the pocket 1. The height and outer diameter of the slag line cylinder 43 with a large diameter at the bottom of the inner cylinder 4 are the required size and position of the slag line. The upper short-diameter cylinder 41 with a small diameter can reduce the overall weight of the inner cylinder 4. The inner cylinder 4 is made of stainless steel to ensure a smooth inner wall, allowing the material to flow in smoothly. In use, Figure 6 The pocket core assembly shown is assembled as follows after removing cap 2. Figure 7 The feeding assembly shown involves adding the main body material into the inner cylinder 4 until material rises, indicating that the lower part of the main body material is full. A measured amount of slag line material is then added through the gap between the inner cylinder 4 and the centering 5. After accurate measurement, the main body material is used to cover the gap until the cylinder is completely full. The feeding assembly is then pulled out, and the cap 2 is replaced with the head material, completing the product feeding process. The entire feeding process is quick and convenient, improving efficiency, reducing workload, and lowering the production cost of the bags.
