Description

Technical Field

[0001] This utility model belongs to the technical field of mining mills, and in particular relates to a detachable two-stage feeding device for a mining mill. Background Technology

[0002] The ore mill is a core piece of equipment in the mineral processing flow. Its main function is to grind ore into powder through mechanical forces such as impact and grinding, thereby effectively separating valuable minerals from gangue and preparing for subsequent separation operations. Its basic working principle is that the rotating cylinder drives the internal grinding media (such as steel balls, steel rods, or the ore itself) to move, crushing the material through throwing and cascading. During the feeding process, the ore material is conveyed into the ore mill. However, the ore mill feeding device still has the following drawbacks in actual use: When the feeding device of the ore mill is in operation, it is directly installed on the ore mill. During the conveying process, the material is directly fed into the feeding device through the feeding structure. During the conveying process, the ore particles are easily blocked due to their different sizes and mutual obstruction, which can cause a "bridging" phenomenon (i.e., the material is blocked at the feed inlet), affecting the smoothness of the feeding. Secondly, during the feeding process of the ore mill, the ore falls directly into the mill after entering the device, resulting in a large impact. Over a long period of operation, this can easily lead to damage to the internal components of the mill, affecting the safety of the equipment. Utility Model Content

[0003] The purpose of this utility model is to provide a detachable two-stage feeding device for a ore mill. By setting up a conveying bin, a fixed plate and a flexible frame, it solves the problem that the bridging and blockage of the ore mill feeding device is easy to occur, which affects the smoothness of feeding, and that the ore impacting the internal parts of the ore mill is easy to cause damage.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a detachable two-stage feeding device for a mining mill, comprising a conveying chamber, fixed plates, and a flexible frame. Several fixed rods are evenly spaced on the lower part of the inner wall of the conveying chamber, and wear-resistant strips are evenly spaced on the top of all the fixed rods. Two fixed plates are fixed on both sides of the conveying chamber. The conveying chamber is inclined, with an opening at the downward-sloping end. A flexible frame is fixed to the downward-sloping end of the conveying chamber, and a conveying plate is fixed to the lower part of the flexible frame on the side away from the conveying chamber. The inclined conveying chamber has wear-resistant strips installed inside via fixed rods to receive and buffer falling ore materials. The opening at the bottom of the inclined chamber connects to the flexible frame, and a conveying plate is installed at the end of the flexible frame to guide the material to the next stage of equipment. The fixed plates on both sides of the conveying chamber are used to connect to external support structures.

[0005] Furthermore, a fixing port is provided on the top of the conveying chamber. The fixing port is located at the end of the conveying chamber that is open away from the conveying chamber. The fixing port on the top of the conveying chamber is used to connect the feeding frame, so as to realize the channel for materials to enter the conveying chamber from the upper equipment.

[0006] Furthermore, a feeding frame is fixed to the outside of the fixed opening at the top of the conveying bin, and an installation frame is fixed to the upper part of the outside of the feeding frame. An installation hole is opened through each corner of the installation frame. The feeding frame is fixedly connected to the upstream feeding equipment with bolts through the installation frame and the installation hole at the top, ensuring that the material is smoothly input into the conveying bin.

[0007] Furthermore, each of the fixed plates has a rectangular array of damping springs fixed to its bottom, and all the damping springs at the bottom of each fixed plate are fixed to a support pile. Each fixed plate has multiple sets of damping springs at its bottom, and the lower ends of the springs are fixed to the support pile. This is used to reduce the transmission of vibration from the conveying chamber to the ground and maintain the stability of the equipment.

[0008] Furthermore, a vibration motor is fixed in the middle of both sides of the conveying chamber, and two fixing plates on the same side of the conveying chamber are set on both sides of the vibration motor. Vibration motors are installed in the middle of both sides of the conveying chamber to cause the chamber to vibrate, prevent materials from clogging between the wear-resistant strips, and improve conveying efficiency.

[0009] Furthermore, a second mounting frame is fixed to the outside of the flexible frame. A second mounting hole is provided through each corner of the second mounting frame. The second mounting frame is provided on the outside of the flexible frame. The second mounting frame is connected to the feed inlet of the ore mill through the second mounting hole and bolts to achieve flexible and sealed installation, thereby reducing vibration transmission and material impact.

[0010] This utility model has the following beneficial effects: This invention solves the problem of bridging and blockage in the feeding device of a ore mill, which affects the smoothness of feeding, by setting up a conveying bin and a fixed plate. During operation, the material is conveyed into the feeding frame and then into the conveying bin. After falling onto the fixed rod in the conveying bin, the fixed rod is positioned in a suitable location. As the ore material passes between the fixed rods, the conveying bin is driven to vibrate by a vibrating motor. During the vibration of the conveying bin, the wear-resistant strips vibrate, and smaller ore objects fall to the bottom of the conveying bin. At the same time, the vibration conveys the ore material, allowing it to be smoothly conveyed into the flexible frame. This makes the ore mill feeding device less prone to bridging and blockage, ensuring the smoothness of feeding.

[0011] This invention solves the problem of ore being easily damaged by impact with the internal components of a ore mill by setting up a conveying bin and a flexible frame. The conveying plate is placed inside the ore mill. After the conveying bin and the installation device at the input end of the ore mill are installed, the conveying plate is positioned at the feed position of the ore mill. After the bottom of the conveying bin and the wear-resistant strips separately convey the ore material, the ore material enters the flexible frame and falls onto the conveying plate. The conveying plate guides the ore into the ore mill, reducing the impact of the ore being directly fed into the mill. The ore conveyed by the ore mill's feed device will not impact the internal components of the ore mill at high speed, protecting the internal components and preventing damage from impact.

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0016] Please see Figure 1-5 This utility model relates to a detachable two-stage feeding device for a ore mill, comprising a conveying chamber 1, a fixing plate 3, and a flexible frame 4. Several fixing rods 103 are evenly spaced on the lower part of the inner wall of the conveying chamber 1. During operation, the conveying chamber 1 transfers ore internally and then conveys it to the next production equipment (i.e., the ore mill). Wear-resistant strips 104 are connected and fixed within the conveying chamber 1 via the fixing rods 103. All fixing rods 103 have wear-resistant strips 104 evenly spaced at their tops. When the ore to be conveyed falls onto the wear-resistant strips 104, the finer ore is conveyed to the bottom of the conveying chamber 1. The bottom of the conveyor is used for transfer and output. Two fixed plates 3 are fixed on both sides of the conveyor 1. The fixed plates 3 connect the support structure to the conveyor 1. The conveyor 1 is set at an inclination, and the downward inclined end of the conveyor 1 is open to facilitate material conveying. A flexible frame 4 is fixed at the downward inclined end of the conveyor 1. The flexible frame 4 reduces the vibration of the conveyor 1 and transmits it to the ore mill. A conveying plate 402 is fixed at the lower part of the side of the flexible frame 4 away from the conveyor 1. The conveying plate 402 extends into the subsequent production equipment and guides the graded conveyed material to the next production equipment.

[0017] Specifically, the top of the conveying chamber 1 is provided with a fixing port 101. The fixing port 101 is located at the end of the conveying chamber 1 that is open. During operation, the conveying chamber 1 is fixed to the feeding frame 2 through the fixing port 101, and the feeding frame 2 is used to transport materials into the conveying chamber 1.

[0018] Furthermore, a feeding frame 2 is fixed to the outside of the fixed opening 101 at the top of the conveying bin 1, so that the conveying bin 1 is connected to the conveying bin 1. An installation frame 201 is fixed to the upper part of the outside of the feeding frame 2. An installation hole 202 is opened through each corner of the installation frame 201. The conveying bin 1 conveys the material to the next production equipment through the feeding frame 2. After the installation frame 201 contacts the output end of the upper feeding equipment, and the installation hole 202 is aligned with the output end hole of the upper feeding equipment, the installation bolts are inserted into the installation frame 201 and then screwed into the output end of the upper feeding equipment and tightened, so that the ore material is conveyed into the feeding frame 2.

[0019] Furthermore, a vibration motor 102 is fixed in the middle of both sides of the conveying chamber 1. Two fixing plates 3 on the same side of the conveying chamber 1 are set on both sides of the vibration motor 102. The conveying chamber 1 drives the material passing through it to vibrate through the vibration generated by the vibration motor 102, so as to prevent the ore material from getting stuck between the adjacent wear-resistant strips 104.

[0020] The operation process of this embodiment is as follows: During operation, firstly, align the mounting frame 201 at the top of the feeding frame 2 with the output end of the upper feeding device, insert the mounting bolts into the mounting holes 202 of the mounting frame 201, and then screw in the upper feeding device and tighten it. When the operation starts, the material is conveyed into the feeding frame 2 and then into the conveying bin 1. It falls onto the wear-resistant strip 104 at the top of the fixed rod 103 through the conveying bin 1. The vibration motor 102 drives the conveying bin 1 to vibrate, and the vibration of the conveying bin 1 causes the wear-resistant strip 104 to vibrate. Smaller ore objects fall to the bottom of the conveying bin 1. At the same time, the vibration conveys the ore material, so that the ore material is smoothly conveyed into the flexible frame 4. Specific Implementation Example 2

[0021] Please see Figure 1 , 2 6. Based on the specific embodiment one, each fixed plate 3 has a rectangular array of damping springs 301 fixed at its bottom. All the damping springs 301 at the bottom of each fixed plate 3 are fixed with a support pile 302. The fixed plate 3 reduces the vibration transmitted to the support pile 302 through the damping springs 301 and is supported on the ground by the support pile 302.

[0022] Specifically, a second mounting frame 401 is fixed to the outside of the flexible frame 4. Each corner of the second mounting frame 401 is provided with a second mounting hole 403. The flexible frame 4 is movably connected to the mounting bolts through the second mounting holes 403 on the second mounting frame 401. After the mounting bolts pass through the second mounting frame 401, they are screwed into the feed position of the ore mill, thus installing the conveying chamber 1 together with the ore mill, so that the ore material is conveyed into the ore mill.

[0023] The operation process of this embodiment is as follows: During operation, the conveyor plate 402 is first placed in the ore mill. After the installation device of the conveyor bin 1 and the input end of the ore mill is installed, the conveyor plate 402 is set at the feed position of the ore mill. After the bottom of the conveyor bin 1 and the wear-resistant strip 104 separately convey the ore material, the ore material enters the flexible frame 4 and falls onto the conveyor plate 402. It is then guided and conveyed into the ore mill by the conveyor plate 402, reducing the large impact caused by the direct conveying of ore into the ore mill.
