Description

Technical Field

[0001] This utility model relates to the field of diversion sand, specifically a high-quality steel ladle diversion sand feeding device. Background Technology

[0002] In the iron and steel metallurgical industry, the accurate addition of ladle sand is crucial for the smooth flow of molten steel, directly affecting the efficiency and quality of steel production. Existing high-quality ladle sand feeding devices primarily employ a rotating grooved roller to achieve quantitative feeding. The working principle of this device is that the rotation of the roller utilizes the grooves on its surface to receive and transport the sand, thereby achieving quantitative control of the feeding amount.

[0003] However, in practical applications, significant problems were found in the feeding process of the guiding sand. Due to the particle characteristics of the guiding sand itself, the sand particles tend to support each other when entering the feeding device, forming an open structure. This open structure results in a large number of gaps between the guiding sand particles, preventing the guiding sand entering the drum groove from filling tightly, and causing a significant deviation between the actual filling amount and the theoretically designed quantitative value.

[0004] If this happens, it will seriously affect the accuracy of material feeding and make the quality of molten steel unstable. Utility Model Content

[0005] The purpose of this invention is to provide a high-quality steel ladle guide sand feeding device. By using this device, the problem of sand particles supporting each other and forming an open structure when entering the feeding device is solved due to the particle characteristics of the guide sand itself. This open structure results in a large number of gaps between the guide sand particles, which prevents the guide sand entering the drum groove from filling tightly and causes a large deviation between the actual filling amount and the theoretically designed quantitative value.

A guide groove is formed on the inner side of the first groove. A support cylinder is fixedly connected to the rotating discharge cylinder inside the first groove. A guide rod is fixedly connected to the support cylinder inside the guide groove. A third groove is disposed in the middle of the rotating discharge cylinder. Multiple equidistant first paddles are fixedly connected to the inner wall of the third groove. A second paddle is fixedly connected to the rotating discharge cylinder on one side of the first paddle. A third paddle is disposed inside the second paddle. A support rod is fixedly connected to the first push rod inside the third paddle.

[0009] Preferably, the inner side of the first groove fits against the outer side of the support cylinder, and the support cylinder has a cylindrical shape.

[0010] Preferably, the guide groove is composed of multiple interconnected "V"-shaped grooves.

[0012] Preferably, the central axis of the third paddle is parallel to the central axis of the first paddle, and the central axis of the third paddle is perpendicular to the central axis of the second paddle.

[0013] Preferably, the rotating discharge cylinder has a second groove inside both sides, and the rotating mechanism includes a fourth paddle fixedly connected to the inside of the second groove, and a fifth paddle fixedly connected to the outer shell on one side of the fourth paddle.

[0021] 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.

[0022] Please see Figures 1-4 The present invention provides a technical solution: a high-quality steel ladle sand feeding device, comprising a shell 1, a feed inlet 2 located above the shell 1, a discharge outlet 9 located below the shell 1, a rotating discharge cylinder 3 located inside the shell 1, a motor 4 fixedly connected to the outside of the shell 1 and fixedly connected to the rotating discharge cylinder 3 and the shell 1, a reciprocating assembly 5 inside the rotating discharge cylinder 3, and a rotating mechanism 6 located on both sides of the rotating discharge cylinder 3;

[0023] The outer casing 1 has a hole 7 on the side away from the motor 4. The reciprocating assembly 5 includes a first push rod 501 disposed inside the hole 7. The first push rod 501 has a first groove 502 inside. The inner side of the first groove 502 has a guide groove 503. A support cylinder 504 fixedly connected to the rotating discharge cylinder 3 is disposed inside the first groove 502. A guide rod 505 fixedly connected to the support cylinder 504 is disposed inside the guide groove 503. A third groove 506 is disposed in the middle of the rotating discharge cylinder 3. Multiple equidistantly distributed first paddles 507 are fixedly connected to the inner wall of the third groove 506. A second paddle 508 fixedly connected to the rotating discharge cylinder 3 is disposed on one side of the first paddle 507. A third paddle 509 is disposed inside the second paddle 508. The inner side of the three-paddle 509 is fixedly connected to the support rod 510, which is fixedly connected to the first push rod 501. The inner side of the hole 7 is in contact with the outer side of the first push rod 501, and the appearance structure of the first push rod 501 is cuboid. The inner side of the first groove 502 is in contact with the outer side of the support cylinder 504, and the appearance structure of the support cylinder 504 is cylindrical. The guide groove 503 is composed of multiple grooves with an appearance structure of "V" connected together. The central axis of the third groove 506 is on the same straight line as the central axis of the first groove 502. The central axis of the third paddle 509 is parallel to the central axis of the first paddle 507, and the central axis of the third paddle 509 is perpendicular to the central axis of the second paddle 508. The inner sides of the rotating discharge cylinder 3 are provided with second grooves 8.

[0024] The rotating discharge cylinder 3 has a second groove 8 inside both sides. The rotating mechanism 6 includes a fourth paddle 601 fixedly connected to the inside of the second groove 8. A fifth paddle 602 fixedly connected to the outer shell 1 is provided on one side of the fourth paddle 601. There are multiple fourth paddles 601 and fifth paddles 602, and the fourth paddles 601 and fifth paddles 602 are all distributed in a circular and equidistant manner.

[0025] When material needs to be discharged, the guiding sand is fed from the feed inlet 2, so that the guiding sand enters the groove of the rotating discharge cylinder 3. The motor 4 is started to drive the rotating discharge cylinder 3 to rotate, which in turn drives the support cylinder 504 and the guide rod 505 to rotate. Since the guide groove 503 is composed of multiple "V"-shaped grooves connected together, the guide groove 503 is pushed by the trajectory of the guide rod 505 to drive the first push rod 501 to reciprocate, which in turn drives the support rod 510 and the third paddle 509 to reciprocate. This causes the first paddle 507 and the second paddle 508 to vibrate. Since the central axis of the third paddle 509 is parallel to the central axis of the first paddle 507 and perpendicular to the central axis of the second paddle 508, the rotating discharge cylinder 3 is subjected to vibration in different directions, which reduces the gap between the guiding sand and improves the accuracy of material discharge.

[0026] When the discharge cylinder 3 rotates, it drives the fourth deflector 601 to rotate, causing the fourth deflector 601 to collide with the fifth deflector 602, reducing the gap between the guiding sand and improving the accuracy of material discharge.

[0027] The vibration between the paddles makes the discharge of the rotating discharge cylinder 3 more efficient, reduces the amount of sand that stays inside the rotating discharge cylinder 3, and further improves the accuracy of material discharge.
