Description

Technical Field

[0001] This utility model relates to the field of ore cleaning technology, and in particular to an ore cleaning device for mining. Background Technology

[0002] During the mining process, ore often becomes contaminated with a large amount of impurities such as soil, rock fragments, and organic matter. For example, in open-pit iron ore mining, the surface of the ore is often covered with a large amount of weathered soil and rock. Washing can remove these impurities, thereby relatively increasing the grade of the ore (the content of useful components).

[0003] Therefore, an ore washing device, disclosed in CN222856142U, is used for ore mining. The ore is poured into the shaking mechanism. After the ore is poured, the drive motor is started, and the connecting shaft 8 rotates to drive the shaking plate to shake. The ore on the surface is then subjected to force and rolls back and forth. The guide hose is connected to the washing water source. The washing water enters the water storage box and then flows into multiple water pipes. It is then sprayed out by the spray head to wash the ore. During the shaking process, the washing water passes through the screening screen and enters the receiving box, and then is discharged through the drain hole on the receiving box. At the same time, small pieces of ore that leak out during the shaking process are collected by the receiving box. When the small ore receiving box is full, the support platform is pulled out by the handle for recycling. After the ore is washed, the shaking plate can be driven in one direction to rotate and pour out the ore. Then, the subsequent ore can be received.

[0004] In existing technologies, ores are usually piled together during the cleaning process, and the cleaning water is sprayed only from above. When the ores are piled together, only the surface ores can fully contact the water flow, while the contact range between the internal buried ores and the water flow is small, resulting in the impurities and harmful substances in the internal ores not being effectively cleaned. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a mining ore washing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a mining ore cleaning device, comprising a frame, wherein a longitudinally lifting U-shaped plate is inserted into the frame, and several layers of partition frames are slidably installed on the U-shaped plate relative to its inner wall. Hydraulic rods are fixedly installed at the four corners of the bottom edge of each partition frame. In two adjacent partition frames, the hydraulic rod cylinder at the bottom of the upper partition frame is fixedly installed on the top of the lower partition frame, and the hydraulic rod cylinder at the bottom of the lower partition frame is fixedly installed on the bottom of the U-shaped plate. The upper and lower surfaces of the partition frames are hollowed out, and several rotary joints are fixedly installed on one inner wall of the partition frame. The central axes of the several rotary joints are arranged in parallel, and a water spray pipe that is rotatably connected to the other inner wall of the partition frame is fixedly installed at the water outlet end of the rotary joint.

[0007] Preferably, a worm gear ring is fixedly installed on the outer wall of the outlet end of the rotary joint, and a worm is rotatably connected to the inner wall of the partition frame and meshes with a plurality of worm gear rings.

[0008] Preferably, a water inlet pipe is fixedly installed on the inner wall of the partition frame. The water inlet pipe passes through the water inlet ends of several rotary joints within the same partition frame. The water inlet pipe is connected to the water inlet ends of the several rotary joints and extends outward through the partition frame.

[0009] Preferably, hydraulic rods are also provided between the bottom of the frame and the four corners of the bottom of the U-shaped plate.

[0010] Preferably, each of the U-shaped plates is slidably mounted with a baffle, the opposite sides of the two baffles are slidably connected to the two sides of the partition frame, the vertical sides of the two baffles are inserted into the outer side of the U-shaped plate and an electric push rod is provided between the baffle and the bottom edge of the outer wall of the U-shaped plate.

[0011] Preferably, guide rods are fixedly installed on both vertical sides of one side of the frame, and lead screws driven by motors are rotatably installed thereon. The guide rods and lead screws are arranged parallel to each other, and a material distribution box is provided between the guide rods and lead screws.

[0012] Preferably, the opening of the material distribution box faces the partition frame and horizontally installed electric telescopic rods are fixedly installed on both outer walls of the material distribution box. The telescopic end of the electric telescopic rod is fixedly installed with a plug that is inserted into the material distribution box in the horizontal direction. The two plugs are set at the same height and are respectively sleeved on the guide rod and threadedly connected to the lead rod.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting several layers of partition frames, when in use, the U-shaped plate moves up and down inside the frame, so that the several layers of partition frames inside move up and down synchronously. The ore to be cleaned is evenly distributed on the surface of each layer of partition frames, so that the thickness of the stack is reduced. By spraying water upward and downward on the partition frames, it is easy to wash the upper and lower surfaces of the layer of ore stacked on the partition frames at the same time, so as to ensure the cleaning effect.

[0015] 2. In this utility model, an electric push rod is used to retract and pull the baffle down, and two baffles are used to block both sides of the partition frame to prevent ore from falling during the cleaning process. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figures 1-4As shown, a mining ore washing device includes a frame 1. A longitudinally lifting U-shaped plate 5 is inserted into the frame 1. Several layers of partition frames 2 are slidably installed on the U-shaped plate 5 relative to its inner wall. During use, the U-shaped plate 5 moves up and down within the frame 1, simultaneously lifting the internal partition frames 2. The ore to be washed is evenly distributed on the surface of each partition frame 2, reducing the thickness of the stack. Water is sprayed upwards and downwards from the partition frames 2, facilitating simultaneous washing of the upper and lower surfaces of the layer of ore stacked on the partition frames 2. Hydraulic rods 11 are fixedly installed at the four corners of the bottom edge of each partition frame 2. In adjacent partition frames 2, the cylinder of the hydraulic rod 11 at the bottom of the upper partition frame 2 is fixedly installed at the top of the lower partition frame 2. The hydraulic rod 11 cylinder at the bottom of the separator 2 is fixedly installed inside the U-shaped plate 5. The hydraulic rod 11 is used to fix the position of the separator 2. The hydraulic rod 11 can be extended and retracted to adjust the spacing between adjacent separator 2 layers according to the size of the ore. The upper and lower surfaces of the separator 2 are hollowed out, and several rotary joints 14 are fixedly installed on one inner wall of the separator 2. The central axes of the rotary joints 14 are parallel, and the water outlet of the rotary joints 14 is fixedly installed with a water spray pipe 12 that is rotatably connected to the other inner wall of the separator 2. The water for cleaning is sprayed out along the water spray pipe 12 through the rotary joints 14. The rotation of the rotary joints 14 causes the water spray pipe 12 to rotate, so that the high-speed water flow can be sprayed to wash the surface of the ore.

[0024] A worm gear ring 13 is fixedly installed on the outer wall of the outlet end of the rotary joint 14. A worm 16 is rotatably connected to the inner wall of the partition frame 2 and meshes with several worm gear rings 13. The worm 16 can be driven by a motor installed on the partition frame 2. The motor drives the worm 16 to rotate. Under the action of meshing connection, the worm gear ring 13 drives the non-fixed end of the rotary joint 14 to rotate, so that the water spray pipe 12 can rotate. A water inlet pipe 15 is also fixedly installed on the inner wall of the partition frame 2. The water inlet pipe 15 passes through the water inlet ends of several rotary joints 14 in the same partition frame 2. The water inlet pipe 15 is connected to the water inlet ends of several rotary joints 14 and extends outward through the partition frame 2. The water inlet end of the water inlet pipe 15 is connected to a water pump through a hose. The water pump uses water for cleaning to enter the movable end along the fixed end of the rotary joint 14 and finally spray out through the water spray pipe 12.

[0025] Hydraulic rods 11 are also installed between the bottom of the frame 1 and the four corners of the bottom of the U-shaped plate 5. The U-shaped plate 5 is reciprocated by the hydraulic rods 11 installed here.

[0026] Each U-shaped plate 5 is slidably fitted with a baffle 3. The opposite sides of the two baffles 3 are slidably connected to the two sides of the partition frame 2. The vertical sides of the baffles 3 are inserted into the outer sides of the U-shaped plate 5, and an electric push rod 4 is installed between the baffles 3 and the bottom edge of the outer wall of the U-shaped plate 5. During the cleaning process, to prevent ore from falling, the electric push rod 4 is used to retract and pull the baffles 3 down, using the two baffles 3 to block the two sides of the partition frame 2, and so on. Figure 1 and combined Figure 2 As shown, there is a strip-shaped notch on the right side baffle 3 at the position of the water inlet pipe 15, to ensure that the baffle 3 will not affect the connection of the water inlet pipe 15 to the hose and water pump when it is lowered.

[0027] Guide rods 7 and motor-driven lead screws 8 are fixedly installed on the vertical sides of one side of the frame 1. The guide rods 7 and lead screws 8 are parallel to each other, and a material distribution box 6 is set between them. The opening of the material distribution box 6 faces the partition frame 2, and horizontally arranged electric telescopic rods 9 are fixedly installed on both outer walls of the material distribution box 6. The telescopic ends of the electric telescopic rods 9 are fixedly installed with inserts 10 that are horizontally inserted into the material distribution box 6. The two inserts 10 are set at the same height and are respectively sleeved on the guide rods 7 and threadedly connected to the lead screws 8. When it is necessary to feed ore from bottom to top onto each layer of partition frame 2, the guide rods 7 and lead screws 8 are fixedly installed on the guide rods 7 and lead screws 8, respectively. The motor drives the lead screw 8 to rotate, and with the assistance of the guide rod 7, the two insert blocks 10 drive the distribution box 6 to rise and fall onto the corresponding layer partition frame 2. The ore is put into the distribution box 6 and slides directly onto the corresponding layer partition frame 2. In order not to affect the subsequent descent of the baffle 3 and to prevent gaps, the electric telescopic rod 9 set on the insert block 10 is used to push the distribution box 6 to slide horizontally between the two insert blocks 10. This allows the opening side of the distribution box 6 to be attached to the side of the partition frame 2, or the opening side of the distribution box 6 to be detached from the side of the partition frame 2, so as to facilitate the descent of the baffle 3.

[0028] The working principle is as follows: Based on the size of the ore to be cleaned, the spacing between two adjacent partition frames 2 is adjusted. With the baffle 3 raised, the distribution box 6 slides and rises against the side of the partition frame 2, driving the screw 8 to rotate. With the assistance of the guide rod 7, the two insert blocks 10 drive the distribution box 6 to rise and fall to the corresponding partition frame 2. The ore is put into the distribution box 6 and slides directly onto the corresponding partition frame 2. After the ore is sorted, the electric telescopic rod 9 set on the insert block 10 is used to push the distribution box 6 to slide horizontally between the two insert blocks 10. One side of the opening of the distribution box 6 is separated from the side of the partition frame 2, which facilitates the lowering of the baffle 3. The U-shaped plate 5 swings up and down in the frame 1, realizing the synchronous up and down movement of several partition frames 2 inside. The ore to be cleaned is evenly distributed on the surface of each partition frame 2, reducing the thickness of the stack. Water is sprayed upwards and downwards from the partition frame 2 to facilitate the simultaneous washing of the upper and lower surfaces of the layer of ore stacked on the partition frame 2.

[0029] The wiring diagrams of the motor, electric push rod 4, electric telescopic rod 9, and hydraulic rod 11 in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the motor, electric push rod 4, electric telescopic rod 9, and hydraulic rod 11 will not be explained in detail.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
