Description

Technical Field

[0001] This application relates to the field of casting technology, and in particular to a flow-through inoculant feeding device and casting equipment. Background Technology

[0002] Currently, in the gray iron casting production process, instantaneous inoculation is used for molten iron inoculation. This means that during the pouring of molten iron, a large number of artificial crystal nuclei are added along with the molten iron flow, forcing the cast iron to undergo eutectic solidification under controlled conditions. This can fully meet the performance requirements of thin-walled, high-quality cylinder blocks. It is crucial to deliver the inoculator in sufficient and accurate quantity to the molten iron flow during pouring. Currently, it is common to use 4-point pipes cut to the required length and then transfer them to the feeding equipment via rubber hoses. Compressed air is used to blow the inoculator onto the molten iron flow. However, during pouring, blockages or damage to the inoculator pipes inevitably occur, requiring replacement of the inoculator pipe or switching to a different inoculator pipe. After replacement or switching of the inoculator pipe, it is difficult to reset the inoculator pipe, resulting in significant changes in the inoculator pipe's posture before and after replacement, which affects the accuracy of the subsequent material feeding process.

[0021] The following reference Figures 1 to 3 The following describes the inoculant feeding device and casting equipment described in the embodiments of this application.

[0022] See Figures 1 to 3 As shown, an embodiment of this application provides a flow-through inoculant feeding device. This device includes a flow-through tube 1, a positioning assembly, and a locking assembly. The positioning assembly includes a positioning member 2 and a positioning sleeve 3. The flow-through tube 1 passes through the positioning sleeve 3, and the positioning member 2 has a through-hole portion. The locking assembly includes a locking member 4, which passes through the through-hole portion and is rotatable relative to the through-hole portion. One end of the locking member 4 protrudes through the through-hole portion and connects to the positioning sleeve 3. Preferably, the connection between the locking member 4 and the positioning sleeve 3 is welded. When the locking member 4 rotates relative to the positioning member 2, the positioning sleeve 3 and the flow-through tube 1 passing through the positioning sleeve 3 rotate synchronously. The positioning member 2 has a positioning portion, and by calibrating and comparing the relative positions of the positioning portion and the positioning sleeve 3, the flow-through tube 1 can be positioned.

[0023] Specifically, the positioning member 2 is flat and fixedly positioned at a designated location. In this embodiment, the positioning member 2 is vertically welded below the molten iron flow channel. One side surface of the positioning member 2 faces the outer wall of the positioning sleeve 3, and the through-hole is a hole structure that penetrates both sides of the positioning member 2. Preferably, the through-hole is located at the center of the positioning member 2.

[0024] The positioning part specifically includes the positioning tip 6 and the positioning scale. The side wall of the positioning member 2 is composed of multiple indexing surfaces, which are distributed along the circumference of the positioning member 2. All the indexing surfaces are connected end to end in sequence. Each indexing surface is a plane, so that an outwardly protruding positioning tip 6 is formed between two adjacent indexing surfaces. All the positioning tips 6 are set at equal intervals along the circumference of the positioning member 2.

[0025] Furthermore, the positioning scale specifically includes a first positioning line and a second positioning line. The side surface of the positioning component 2 facing the positioning sleeve 3 is the positioning surface. Multiple first calibration lines are provided near the edge of the positioning surface. The multiple first calibration lines are equally spaced along the circumference of the positioning surface. The number of first calibration lines is the same as the number of positioning tips 6. Each positioning tip 6 is positioned opposite a first positioning line.

[0026] There are multiple second positioning lines. The same number of second positioning lines are set between any two adjacent first positioning lines. Each first positioning line and each second positioning line extends radially along the positioning member 2. All the first positioning lines and all the second positioning lines are centrally symmetrical about the center of the positioning member 2, so that the positioning member 2 as a whole has a structure and shape similar to a protractor.

[0027] Preferably, a marking line (not shown in the figure) is provided on the outer wall surface of the positioning sleeve 3 facing the positioning member 2. The length of the marking line extends along the length of the positioning sleeve 3, and the marking line is parallel to the axis of the positioning sleeve 3. By comparing the angle between the marking line and the positioning member 2, the angle between the positioning sleeve 3 and the flow tube 1 and the positioning member 2 can be reflected, thereby quantitatively determining the current position of the flow tube 1.

[0028] Preferably, when the marking line deflects from the first positioning line to the second positioning line adjacent to the first positioning line, or when the marking line deflects from the second positioning line to the adjacent second positioning line or the first positioning line, the positioning sleeve 3 and the follower tube 1 rotate by 5°.

[0029] Furthermore, the locking assembly also includes a locking member 5. The locking member 4 is elongated, preferably a screw, and the locking member 5 is a locking nut that can be adapted to connect with the locking member 4. After adjusting the deflection of the positioning sleeve 3 to the correct position according to process requirements, the locking member 5 is used to lock the locking member 4 and the positioning member 2. At this time, the positioning member 2 is tightly clamped between the locking member 5 and the positioning sleeve 3, and the positioning sleeve 3 remains in a fixed position and no longer rotates. The relative position and corresponding angle between the marking line and the positioning part are recorded at this time. When replacing or switching the follower tube 1, the locking member 5 can be removed so that the positioning sleeve 3 and the locking member 4 can be separated from the positioning member 2, which facilitates the replacement of the follower tube 1. After the replacement is completed, the position of the positioning sleeve 3 and the follower tube 1 can be quickly reproduced according to the recorded position and angle.

[0030] Furthermore, the follow-through tube 1 is a long and slender tube. One end of the follow-through tube 1 is the inlet 101, which is used to connect to an external hose. The other end of the follow-through tube 1 is the outlet 102. Preferably, the outlet 102 is a beveled cut, and the plane of the beveled cut forms an angle α with the axis of the follow-through tube 1. Preferably, 30°≤α≤50°. In this embodiment, the outlet 102 is designed as a beveled cut, which increases the opening area compared to a normal round opening, thereby increasing the release flow rate, while also taking into account the ability of the tube opening to constrain the inoculant. During the feeding process, molten iron may splash and solidify on the inoculant tube head, causing blockage. If this is not detected in time and the blockage is not dealt with, the inoculant may be added in insufficient or missed amounts, seriously affecting the casting material, especially the thin-walled cylinder material. In this embodiment, the structure of the outlet 102 is optimized to significantly reduce the probability of blockage at the outlet 102.

[0031] Preferably, the length of the oblique cut is not less than 10 cm, and more preferably 10 cm. It should be noted that the length of the oblique cut here is specifically the axial length of the oblique cut, or the length of the oblique cut that occupies the flow tube 1 along the axial direction.

[0032] Furthermore, the discharge port 102 is provided with a protective layer (not shown in the figure). Preferably, a protective layer is provided on a section of the inner wall surface of the discharge port 102, a section of the outer wall surface of the discharge port 102, and the end face of the discharge port 102. The coverage height of the protective layer is not less than 10 cm. The protective layer is preferably a refractory coating commonly used in the prior art. When molten iron splashes and hangs on the pipe head, it plays a blocking role, reducing the solidification of molten iron on the iron pipe wall. If a small amount of solidification occurs, it is easy to clean. At the same time as discharge, it can wash away some iron slag, which facilitates inspection and processing operations and improves efficiency.

[0033] Furthermore, this inoculant feeding device also includes a detection component, which is used to detect whether the inoculant tube 1 has shifted downwards or detached. The detection component specifically includes: a detection element 8, a detection ring 7, and an alarm 10. The alarm 10 integrates a control board and a controller 9. The detection element 8 is specifically a contactless switch, electrically or communicatively connected to the alarm 10. The detection ring 7 is positioned near the inlet 101 of the inoculant tube 1, surrounding the inoculant tube 1. The detection element 8 is located on an external hose. When the external hose is normally connected to the inlet 101, the detection element 8 can detect the presence of the detection ring 7. When the inoculant tube 1 shifts downwards or detaches, the detection ring 7 leaves the detection range of the detection element 8, and the acquisition signal from the detection element 8 disappears. At this time, the controller 9 controls the alarm 10 to trigger an alarm signal, and the alarm 10 alerts the operator through an audible and visual warning.

[0034] Preferably, the controller 9 is also electrically connected to the control system of the inoculation mechanism of the casting equipment, so that the alarm 10 is linked with the mechanism under other operation processes of the equipment and stops working when there is a problem.

[0035] Preferably, the alarm 10 is provided with a reset button 11 to clear the alarm information after a fault is handled. In summary, the in-flow inoculant feeding device provided in this application, when cutting or replacing the in-flow tube 1, can quantitatively locate the in-flow tube 1 by calibrating and recording its position before disassembly, ensuring accuracy. After switching or replacing the tube, the position can be quickly reproduced, ensuring that the position of the in-flow tube 1 is consistent before and after, thereby avoiding any impact on the subsequent feeding process. This in-flow inoculant feeding device has a simple structure, is easy to operate, is suitable for widespread use, and has strong practicality. The embodiments of this application also provide a casting equipment, including the in-flow inoculant feeding device described in any of the above embodiments, and thus have all the beneficial technical effects of the in-flow inoculant feeding device, which will not be repeated here.

[0036] This casting equipment can significantly improve the accuracy of adjusting the position of the inoculant tube 1 through the above-mentioned in-flow inoculant feeding device. Moreover, the adjustment process is easy to operate and has small errors, which can effectively ensure the stability and reliability of the subsequent feeding process.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
