Description

Technical Field

[0001] The utility model relates to the technical field of returned ore disposal, in particular to a returned ore disposal device for a sintering machine. Background Art

[0002] Sintering machine is suitable for sintering operation in large-scale ferrous metallurgical sintering plants, and is mainly suitable for sintering iron ore powder in large and medium-sized sintering plants. It is the main equipment in the exhaust sintering process, which 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.

[0003] After searching, the patent announcement number CN218554699U discloses a sintering return device with controllable particle size, which relates to the technical field of sintering furnace. The sintering return device with controllable particle size includes two vertical poles, the opposite surfaces of the two vertical poles are fixedly connected with a fixed platform, the top surface of the fixed platform is fixedly connected with a sintering furnace, the top surface of the sintering furnace is fixedly connected with a feed pipe, the bottom surface of the sintering furnace is fixedly connected with a discharge pipe, the lower end of the discharge pipe is fixedly connected with a processing box, the processing box is fixedly connected with the two vertical poles, the processing box is connected with the inside of the discharge pipe, the bottom surface of the processing box is fixedly connected with a discharge hopper, the processing box is connected with the inside of the discharge hopper, and a pushing device is arranged inside the processing box. Through the arrangement of the pushing device, when raw materials with larger particle size accumulate on the vibrating screen, the push plate is used to move, and the raw materials with larger particle size on the vibrating screen are pushed toward the second discharge port and discharged from the second discharge port, so that the vibrating screen can be prevented from being blocked by raw materials with larger particle size, thereby improving the practicality of the device.

[0004] When CN218554699U in the prior art is used, it pushes the raw materials with larger particle size on the vibrating screen toward the second discharge port and is discharged from the second discharge port. This can prevent the vibrating screen from being blocked by the raw materials with larger particle size, thereby improving the practicality of the device. However, in actual screening, the raw materials are still in the screening position after screening, and the direct discharge height is relatively high, so it still needs to be improved. Utility Model Content

[0005] The utility model aims to provide a sintering machine return ore disposal device to solve the problems raised in the above background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a sintering machine return ore disposal device, including a bearing base, a collection box, a sintering furnace and a guide plate,

[0008] A feed pipe 1 is embedded and fixed on the top surface of the sintering furnace, and the sintering furnace is connected to the screening box through a connecting pipe;

[0009] A guide frame is installed on the side end surface of the inner wall of the screening box, and a screen is installed on the inner wall of the screening box;

[0010] A driving mechanism is installed on the side end surface of the guide frame, and a screw rod is arranged on the output shaft of the driving mechanism;

[0012] A fixing tube is installed on the top surface of the bearing base;

[0013] A driving motor is installed on the top surface of the fixed tube, and a spiral blade is installed on the output shaft of the driving motor via a rotating shaft;

[0014] A buffer plate is welded to the inner wall side end surface of the collection box.

[0015] Preferably, a material guide pipe is embedded and fixed on the side end surface of the screening box, and a second material discharge pipe is embedded and fixed on the bottom end surface of the screening box. The material guide pipe allows the raw materials with larger particle sizes on the screen in the screening box to be discharged through the material guide pipe by pushing, and the raw materials that meet the mesh size of the screen can continue to fall and be discharged through the second material discharge pipe.

[0016] Preferably, a support block is welded to the bottom end surface of the bearing base, and there are four support blocks in total, and the four support blocks are distributed in a rectangular array relative to the bearing base. The bearing base can be installed and supported by the support blocks.

[0017] Preferably, the guide plate is slidably sleeved in the guide frame, and the guide plate is installed on the screw rod by means of threads. The guide plate is slidably sleeved in the guide frame for position limiting, and when the position limiting is performed, the guide plate is installed on the screw rod by means of threads, so that a person can open the driving mechanism to drive the screw rod to rotate, and the guide plate can be driven to move left and right in the screening box according to the rotation direction of the screw rod.

[0018] Preferably, one end of the fixed tube is embedded with a feed tube 2, and the end of the fixed tube away from the feed tube 2 is embedded with a discharge tube. The raw materials to be processed by the sintering furnace of the sintering machine can be injected into the feed tube 2 through the feed tube 2. After injection, the personnel can turn on the driving motor to drive the spiral blade to rotate through the rotating shaft, so that the raw materials are spirally moved up and transported to the discharge tube through the fixed tube for discharge.

[0019] Preferably, the front and rear ends of the collection box are both welded with fixing frames, and the bottom end surface of the fixing frame is welded to the bearing base.

[0020] Preferably, a discharge pipe 1 is embedded and fixed on the bottom end surface of the collecting box, and the discharge pipe 1 is connected to the collecting box. The raw materials entering the collecting box can be discharged through the discharge pipe 1.

[0021] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0022] 1. The utility model provides a fixed pipe. When the personnel use the sintering furnace of the sintering machine, the raw materials to be processed by the sintering furnace of the sintering machine can be injected into the feed pipe 2 through the feed pipe 2. After the injection, the personnel can turn on the driving motor to drive the spiral blade to rotate through the rotating shaft, so that the raw material spirally moves up and is transported to the discharge pipe through the fixed pipe for discharge, so that the raw material falls into the sintering furnace through the feed pipe 1. After the injection, it can be processed by the sintering furnace of the sintering machine. The processed raw material can be discharged into the screening box through the connecting pipe, so that the raw material can fall on the screen for return ore disposal. When it falls on the screen, the personnel can install a vibration motor on the bottom end surface of the screen to drive the screen to vibrate, so that the raw material and the return ore can be screened and disposed, thereby meeting the feeding requirements and avoiding the inconvenience of processing caused by the feeding position being too high.

[0023] 2. The utility model provides a collecting box. When personnel use the sintering furnace of the sintering machine, the raw materials can fall on the screen for screening. The large particles of raw materials are on the screen, and then the guide plate is slidably sleeved in the guide frame for limiting. When limiting, the guide plate is installed on the screw rod through a thread, so that the personnel can open the driving mechanism to drive the screw rod to rotate. According to the rotation direction of the screw rod, the guide plate can be driven to move left and right in the screening box, so that the large particles of raw materials can be squeezed and pushed by the limiting frame, and the raw materials are discharged through the material guide pipe. When discharged, the materials are received through the collecting box to avoid the excessively high material discharge position affecting the subsequent processing. Therefore, the raw materials returned after screening fall on the buffer plate for buffering when falling, avoiding the direct discharge into the collection box to cause damage to the collection box, thereby meeting the subsequent material receiving operation and avoiding the excessively high material discharge position affecting the processing.
