Abstract
Description
Technical Field
[0001] This utility model relates to the field of fine mineral recovery technology, specifically to a fine mineral recovery device. Background Technology
[0002] Currently, iron ore mining mostly employs large-diameter deep-hole open-face filling and segmented open-face filling methods. After blasting within the stope, the ore is transported to the stope pass by a loader, and then loaded onto a vibratory ore feeder onto a 12m rail-guided intermediate transport system at -1060m. 3 Mine cars, pulled by electric locomotives, are unloaded at the unloading station into the raw ore bin. After crushing, the ore enters the finished ore bin and is then loaded onto the main shaft skip via a conveyor belt (belt inclined shaft). The ore is then hoisted from the main shaft. During hoisting, fine ore easily falls and accumulates at the bottom of the mine. Traditional methods require manual operation of trackless equipment to recover the fine ore from the bottom of the mine, resulting in high labor intensity and low work efficiency. Therefore, we propose a fine ore recovery device. Utility Model Content

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0017] Please see Figure 1 , Figure 2 and Figure 3This utility model provides a technical solution: a powder ore recovery device, including an inclined chute 1, which is welded from stainless steel plates and is inclined. The inclined chute 1 is located in the middle section of the mine bottom from -1277m to -1060m. One end of the inclined chute 1 is provided with a feed port 2, and the other end of the inclined chute 1 is provided with a discharge port 3. The feed port 2 is located at the bottom of the mine, and the discharge port 3 is located above the conveyor belt of the transport equipment. The powder ore falling in the mine is recovered through the inclined chute 1 and introduced into the conveyor belt of the transport equipment. Then, the powder ore is transferred from the bottom of the mine to the external silo by the conveyor belt. This effectively avoids the accumulation of powder ore at the bottom of the mine, realizes the mechanization and automation of powder ore cleaning, and reduces labor intensity.
[0018] A reinforcing block 8 is welded and fixed to the outer wall of the feed port 2. The reinforcing block 8 strengthens the overall strength of the feed port 2 and prevents the powder from impacting the feed port 2 during its fall, causing deformation and damage.
[0019] like Figure 2 As shown, a guide plate 4 is detachably and fixedly mounted on the inner wall of the feed port 2 by fixing bolts and fixing nuts. The guide plate 4 is inclined and guides the powder entering the feed port 2 so that the powder falls into the inclined chute 1.
[0020] like Figure 2 As shown, the inner cavity of the inclined chute 1 is detachably and fixedly fitted with an inner liner 5 by fixing bolts and fixing nuts. The inner liner 5 is V-shaped. By setting the inner liner 5, the turning point of the inclined chute 1 is protected, so as to avoid the powder ore from impacting the side wall of the inclined chute 1 during the falling process, causing deformation and damage inside the inclined chute 1.
[0021] like Figure 2 As shown, a vibration mechanism 6 is fixedly mounted at the bottom of the discharge port 3. The vibration generated by the vibration mechanism 6 facilitates the discharge of material from the discharge port 3 onto the surface of the conveyor belt. Figure 2 and Figure 3As shown, the vibration mechanism 6 includes an inclined frame 61, which is mounted at the bottom of the discharge port 3. Connecting shafts 62 that pass through the inclined chute 1 are fixedly connected to the four corners of the bottom of the inclined frame 61. A fixed frame 64 is welded and fixed to the bottom of the discharge port 3. A fixed shaft 65 is welded and fixed inside the fixed frame 64. The connecting shaft 62 is inserted into the fixed shaft 65. A support spring 66 is mounted between the connecting shaft 62 and the fixed shaft 65. A mounting plate 67 is welded and fixed between the connecting shafts 62. A vibration motor 63 is fixedly mounted at the bottom of the mounting plate 67. The vibration motor 63 is electrically connected to an external power supply and an external controller. The vibration motor 63 can drive the inclined frame 61 to vibrate within a certain range at the bottom of the discharge port 3, so as to avoid blockage when the powder passes through the inclined frame 61 and facilitate downward feeding.
[0022] like Figure 2 and Figure 3 As shown, a purging mechanism 7 is fixedly installed at the top of the discharge port 3. The purging mechanism 7 can purge the surface of the inclined frame 61 below to prevent wet and sticky materials from sticking to the inclined frame 61, thereby affecting the subsequent feeding operation of powdered ore.
[0023] The purging mechanism 7 includes a mounting block 71, which is fixedly connected to the top of the inner cavity of the discharge port 3. The bottom of the mounting block 71 has a mounting groove 72, and the inner cavity of the mounting groove 72 is fixedly fitted with an air outlet pipe 73. Air outlet nozzles 74 are evenly fixedly fitted at the bottom of the air outlet pipe 73. One end of the air inlet pipe 75 is fixedly connected to the top of the air outlet pipe 73. The other end of the air inlet pipe 75 passes through the mounting block 71 and the inclined chute 1. The mounting block 71 protects the air outlet pipe 73 to prevent the powder from damaging the air outlet pipe 73 during the falling process. The air inlet end of the air inlet pipe 75 is connected to an external air compressor. High-pressure gas is introduced into the air inlet pipe 75 and the air outlet pipe 73 through the external air compressor. The high-pressure gas is sprayed downward from the air outlet nozzles 74 to purge the surface of the inclined frame 61.
[0024] Working principle: This utility model is installed near the bottom of the mine. During the upward transportation of mined ore by the mine hoist, the powder ore that falls will enter the inclined chute 1 through the feed port 2, and then enter the conveyor belt of the conveyor through the discharge port 3. The inclined chute 1 can transfer the powder ore in time, avoiding the accumulation and residue of powder ore at the bottom of the mine. The bottom of the discharge port 3 is equipped with a vibration mechanism 6, which can effectively prevent the powder ore from blocking the discharge port 3 during the discharge process. At the same time, a blowing mechanism 7 is installed at the top of the discharge port 3. When no powder ore passes through the discharge port 3, the blowing mechanism 7 can be opened periodically to effectively reduce the adhesion of material to the surface of the inclined frame 61 during discharge, and clean the inclined frame 61 in time.
