Description

Technical Field

[0001] The utility model provides an automatic material distribution mechanism for a sintering machine, and relates to the technical field of sintering machines. Background Art

[0002] The sintering machine is suitable for the sintering operation of large-scale ferrous metallurgical sintering plants. It is the main equipment in the exhaust sintering process. It can sinter concentrate powder and rich ore powder of different components and different particle sizes into blocks, and partially eliminate harmful impurities such as sulfur and phosphorus contained in the ore. When the existing sintering machine is spreading, the mixed material is usually sent into the buffer silo by a shuttle conveyor. The bottom of the buffer silo is equipped with a main gate that can control the discharge rate and a roller for guidance. A nine-roller spreading machine is usually set under the roller. The above equipment completes the spreading process together, and the mixed material is evenly laid on the sintering trolley from top to bottom and from fine to coarse according to the particle size.

[0003] In order to distribute the materials evenly, the mixed materials in the buffer silo will not be discharged until the silo is more than half full. The mixed materials are easy to adhere to the inside of the silo and gradually block the discharge port. In the prior art, a method of installing a vibration motor on the outer wall of the silo near the discharge port is used to solve the blockage problem. However, due to the large volume of the buffer silo used for sintering machine distribution and the integral welding of the silo and the foundation support beam, this method of vibrating from the outside of the silo does not achieve good results. Therefore, we propose an automatic distribution mechanism for sintering machines. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the buffer bin is easily blocked when the sintering machine is distributing materials.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is as follows: an automatic feeding mechanism of a sintering machine includes a buffer silo, a vibration mechanism is arranged in the buffer silo, and the vibration mechanism includes a vibration seat, vibration rods symmetrically fixed on both sides of the vibration seat, a vibration plate detachably mounted on the vibration rods, and a mounting seat fixed to the inner wall of the buffer silo, and one end of the vibration rod away from the vibration seat is movably inserted into the inner side of the mounting seat.

[0006] Preferably, a mechanism cavity is provided in the vibration seat, and a vibration motor is fixedly installed in the mechanism cavity.

[0007] Preferably, a guide block is symmetrically fixed to the end of the vibration rod, a guide groove matching the guide block is opened on the inner side of the mounting seat, and the guide block is slidably placed inside the guide groove.

[0008] Preferably, the width of the guide groove is greater than the width of the guide block.

[0009] Preferably, one end of the vibration rod close to the mounting seat is also fixedly connected to a spring, the other end of the spring is fixedly connected to a mounting head, and the mounting head is rotatably connected to the inner side of the mounting seat through a bearing.

[0010] Preferably, a fixer is provided between the vibration plate and the vibration rod, and the fixer includes a fixing hoop, side ears fixed to both sides of the fixing hoop, and a socket fixed to the top of the fixing hoop. One end of the vibration plate is provided with a plug matching the socket, and the side ears and the socket and the plug are fixed by bolts and nuts.

[0011] Preferably, a positioning key is fixedly connected to the inner side of the fixing hoop, and a key slot matching with the positioning key is formed on the side wall of the vibration rod.

[0012] Beneficial effects of the utility model:

[0013] By setting up a vibration mechanism, the mixture can be vibrated directly from the inside of the buffer silo through the vibration mechanism during discharging, so as to prevent the mixture from adhering to the inner wall of the buffer silo during discharging and causing blockage of the discharging port, thereby solving the problem that the vibration motor set outside the buffer silo in the prior art cannot solve the blockage problem well.

[0020] The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

[0021] Reference Figures 1 to 5 The utility model provides an automatic feeding mechanism for a sintering machine, including a buffer bin 1, which is used to store mixed materials during feeding. A feeding port is provided at the bottom of the buffer bin 1, and a vibration mechanism is provided in the buffer bin 1. The vibration mechanism includes a vibration seat 5, vibration rods 3 symmetrically fixed on both sides of the vibration seat 5, a vibration plate 4 detachably mounted on the vibration rod 3, and a mounting seat 2 fixed to the inner wall of the buffer bin 1, and one end of the vibration rod 3 away from the vibration seat 5 is movably inserted into the inner side of the mounting seat 2. Specifically, the mounting seat 2 supports the vibration rod 3 and the vibration rod 3 can move in the mounting seat 2, and vibration can be generated by the vibration seat 5 and transmitted to the vibration rod 3 and the vibration plate 4, so that the mixed material in the buffer bin 1 is vibrated by the vibration plate 4, so as to avoid the mixed material adhering to the bin wall of the buffer bin 1 during the feeding process, resulting in the blocking of the feeding port of the buffer bin 1.

[0022] Furthermore, if Figure 5 As shown, a mechanism cavity 17 is provided in the vibration seat 5, and a vibration motor 18 is fixedly installed in the mechanism cavity 17. Specifically, vibration is generated by the vibration motor 18, and the vibration motor 18 is a prior art, so its specific structure and working principle will not be described in detail.

[0023] Furthermore, if Figure 2 , Figure 3 As shown, the end of the vibration rod 3 is symmetrically fixed with a guide block 10, and the inner side of the mounting seat 2 is provided with a guide groove 9 that matches the guide block 10, and the guide block 10 is slidably placed inside the guide groove 9. Specifically, through the cooperation of the guide groove 9 and the guide block 10, the vibration rod 3 can vibrate left and right in its own axial direction, and at the same time, the guide groove 9 restricts the guide block 10, so that the end of the vibration rod 3 is always on the inner side of the mounting seat 2; further, the width of the guide groove 9 is greater than the width of the guide block 10, so that the vibration rod 3 can also rotate in a small range in its own circumferential direction, so that the vibration plate 4 can rotate in a small range with the vibration rod 3 as the center while vibrating left and right, thereby expanding the range of vibration.

[0024] Furthermore, if Figure 3 As shown, a spring 7 is fixedly connected to one end of the vibration rod 3 near the mounting seat 2, and a mounting head 6 is fixedly connected to the other end of the spring 7. The mounting head 6 is rotatably connected to the inner side of the mounting seat 2 through a bearing. Specifically, the spring 7 can support the end of the vibration rod 3, and at the same time, the springs 7 on the left and right sides are continuously squeezed and stretched, and the vibration effect is better under the reaction force of the spring 7.

[0025] Furthermore, if Figure 4As shown, a fixer 8 is provided between the vibration plate 4 and the vibration rod 3, and the fixer 8 includes a fixing hoop 13, side ears 14 fixed to both sides of the fixing hoop 13, and a socket 15 fixed to the top of the fixing hoop 13. A plug 16 matching the socket 15 is provided at one end of the vibration plate 4, and the side ears 14, the socket 15 and the plug 16 are fixed by bolts and nuts. Specifically, by setting the fixer 8, the vibration plate 4 and the vibration rod 3 can be detachably connected, which is convenient for maintenance of the vibration plate 4.

[0026] Furthermore, if Figure 4 As shown, a positioning key 12 is fixedly connected to the inner side of the fixing hoop 13, and a key slot 11 matching the positioning key 12 is formed on the side wall of the vibration rod 3. Specifically, the positioning key 12 is inserted into the key slot 11 to prevent the fixing hoop 13 from sliding left and right.

[0027] Working principle: Start the vibration motor 18, generate vibration through the vibration motor 18, and transmit the vibration to the vibration rod 3 and the vibration plate 4. While the vibration plate 4 vibrates left and right, it can also rotate in a small range with the vibration rod 3 as the center. The mixed material in the buffer silo 1 is vibrated by the vibration plate 4, so as to avoid the mixed material adhering to the silo wall of the buffer silo 1 during the discharge process, causing the discharge port of the buffer silo 1 to be blocked.

[0028] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
