Description

Technical Field

[0001] This utility model relates to the field of metallurgical equipment technology, specifically to a quantitative material addition device for metallurgical applications. Background Technology

[0002] Metallurgical material addition refers to the operation of adding various raw materials and additives to equipment such as furnaces and reaction vessels during the metallurgical production process. Some powdery materials usually need to be added in a quantitative manner. The existing addition method usually uses a motor to directly drive a feeding component with multiple partitions to complete the material feeding.

[0003] While existing feeding methods are simple and convenient, they cannot guarantee that the powder will fill the space when it enters the partition. This results in inconsistent amounts of material in each partition, which can easily lead to a decline in the quality of the manufactured metal and cause considerable inconvenience. Therefore, a metallurgical material quantitative addition device is proposed to solve the above-mentioned problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a quantitative material addition device for metallurgical applications. It has the advantage of ensuring the uniformity of materials within the partition during the feeding process. This solves the problem that while existing feeding methods are simple and convenient, they cannot guarantee that the powder will fill the space when it enters the partition, resulting in inconsistent amounts of material within the partition each time. This can easily lead to a decline in the quality of the manufactured metal and cause significant inconvenience.

[0009] This metallurgical material quantitative addition device has the advantage of ensuring the uniformity of materials within the partition during the feeding process.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the feeding frame consists of a feeding roller and spacers. There are six spacers distributed in a ring at equal intervals outside the feeding roller. There is rotational damping between the feeding roller and the feeding cylinder.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the rotational damping can ensure that the material cannot rotate naturally under its own weight when there is material inside, thus ensuring the feeding effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the embodiments, by Figure 1-3 The present invention discloses a material quantitative addition device for metallurgical applications. The device includes a feeding cylinder 1, an external feed pipe 2 extending above the feeding cylinder 1 and eccentrically positioned thereon, a feeding rack 3 positioned between the front and rear walls of the inner side of the feeding cylinder 1, a pushing block 4 that can slide up and down along the pipe wall inside the feed pipe 2, a linear pushing member 5 that drives the pushing block 4 to move up and down outside the feed pipe 2, an inlet pipe 6 located below the lower limit of the pushing block 4 connected to the external side of the feed pipe 2, a circulation pipe 7 connected at the other end of the inlet pipe 6 connected to the feed pipe 2, the connection between the circulation pipe 7 and the feed pipe 2 being located at the upper limit of the pushing block 4, a feeding container 8 connected to the end of the inlet pipe 6, and a discharge hole 9 opened at the bottom of the feeding cylinder 1.

[0027] Furthermore, the feeding frame 3 is composed of a feeding roller 31 and a spacer plate 32. There are six spacer plates 32, which are distributed in a ring at equal intervals outside the feeding roller 31. There is rotational damping between the feeding roller 31 and the feeding cylinder 1.

[0028] By setting up partition plates 32, powdery materials can fall into the space between the partition plates 32 when they enter, thereby completing the storage and transportation of materials.

[0029] Furthermore, the thickness of the partition plate 32 on the side away from the feed roller 31 is greater than the distance on the side closer to the feed roller 31, and the width of the discharge hole 9 is less than the distance between the two adjacent partition plates 32 on the side away from the feed roller 31.

[0030] Furthermore, the outside of the feeding cylinder 1 is provided with a detection element whose direction is opposite to that of the feeding pipe 2. When the detection element is triggered, the gap between two adjacent partition plates 32 is aligned with the discharge hole 9. The detection element is linked with the linear pusher 5 and controls it.

[0031] The detection component consists of a detection sleeve and a reflective photoelectric switch. When the partition plate 32 moves to the detection component, the reflective photoelectric switch is triggered by the end of the partition plate 32, indicating that the feeding operation is completed and controlling the linear pusher 5 to stop moving until the feeding starts again on the second start.

[0032] Specifically, this device should be used in conjunction with a controller, and the controller should have a built-in timer. The timer should be used to time the interval between two feedings, and the controller should be used to receive and transmit control signals.

[0033] Furthermore, the top of the push block 4 is inclined, and a sealing ring is provided on the outside of the push block 4 to form a seal with the inner wall of the feed pipe 2.

[0034] Furthermore, a material detection sensor 10 is installed inside the feed container 8, and an alarm 11 that is linked to the material detection sensor 10 is installed in the feed container 8.

[0035] Working principle:

[0036] By setting up a feeding cylinder 1, the material is separated and replenished inside the feeding cylinder 1 by the feeding rack 3. In use, the material inside the feeding container 8 arrives at the inside of the feeding pipe 2 through the feeding pipe 6 and falls into the feeding rack 3. Then, the linear pusher 5 pushes the pusher block 4 to start pressing down on the powdered material. Under the action of the downward pressure, the powdered material fills the separation space and pushes the feeding rack 3 to start rotating.

[0037] When the material feeding rack 3 is divided and reaches the discharge hole 9, the material can be discharged directly through the discharge hole 9. When the discharge is completed, the feed pipe 2 and the feeding cylinder 1 complete the new material assembly, and the linear pusher 5 stops moving, waiting for the second feeding action.
