Description

TECHNICAL FIELD

[0001] The utility model relates to ore dehydration technical field especially relates to an ore dehydration device. BACKGROUND

[0002] Ore dehydration refers to the dehydration equipment with high water content of ore to remove certain moisture, so that its water content is reduced to a certain range, the dehydration of mineral by mine equipment is generally separated by mechanical gravity, pressure or centrifugal force, or directly dried by drying equipment.

[0003] In the beneficiation process, the ore with high water content often causes many troubles in beneficiation, such as affecting the grinding effect, increasing the pulp viscosity, reducing the contact between bubbles and particles, etc., and the water content of the lump ore is obviously reduced after dehydration, so these problems can be effectively solved, and the beneficiation efficiency is improved; secondly, the lump ore with high water content occupies more volume in the transportation process, and increases the transportation cost, and the volume of the lump ore after dehydration is smaller and the weight is lighter, which can greatly reduce the transportation cost; in addition, the lump ore with high water content is easy to pollute in the process of transportation and stacking, so dehydration treatment can not only reduce the waste of water resources, but also reduce environmental pollution.

[0004] After retrieval, the utility model with publication number CN213179064U discloses a centrifugal dehydrator for ore dehydration, which comprises a placing cylinder, a sealing cover, a dehydration mechanism, a drive device and a limiting mechanism. The placing cylinder is installed with a sealing cover on one side through a rotating seat. The dehydration mechanism comprises a filter cylinder and a fixed pipe. The bottom of the placing cylinder is centrally rotatably connected with the fixed pipe, and the top of the fixed pipe is fixedly installed with the filter cylinder. The surface of the fixed pipe and outside the placing cylinder are fixedly installed with the drive device. The limiting mechanism comprises a limiting rod, a spring, a limiting disc and a water outlet hole. The application realizes ore dehydration by centrifugal method, but the capacity of the device is limited during single dehydration, so it is necessary to repeatedly start and stop the equipment and take and place the materials when facing the large amount of ore dehydration demand in the mining industry, which leads to the inability of the device to run continuously and the difficulty of efficiently performing the operation. UTILITY MODEL CONTENT

[0005] In view of the above prior art, the utility model provides an ore dehydration device, and the main technical problem to be solved is how to efficiently perform ore dehydration operation.

[0006] To achieve the above purpose, the technical scheme of the utility model embodiment is as follows:

[0007] An ore dewatering device includes a material box, which contains a conveying mechanism and a vibration mechanism. Several air inlets and outlets are respectively opened on both sides of the material box. Fans are fixedly connected to both the air inlets and outlets of the material box. The fans are used to generate airflow in the material box. The conveying mechanism includes a conveyor belt for conveying ore in the airflow. The vibration mechanism includes several rollers. Blades are fixedly connected to the bottom end of the rollers. Several swing arms are fixedly connected to the leeward side of the rollers. The blades are driven by the airflow to strike the conveyor belt and cause vibration.

[0008] Furthermore, a rotating shaft is rotatably connected to one end of the inner wall of one side of the material box, and a circular through hole is opened at one end of the other side of the material box. One end of the rotating shaft extends to the outside of the material box at the circular through hole. A housing is fixedly connected to the outer wall of the material box outside the circular through hole. A motor is fixedly connected inside the housing, and the output shaft of the motor is fixedly connected to the rotating shaft.

[0009] Furthermore, a connecting shaft is rotatably connected between the inner walls of the two sides of the material box on the side away from the rotating shaft. Both ends of the connecting shaft are connected to driven wheels by keys. Both ends of the rotating shaft inside the material box are connected to driving wheels by keys. The two driving wheels correspond to the two driven wheels respectively.

[0010] Furthermore, the same belt is fitted around the corresponding driving and driven wheels on the left and right sides. Several frames are fixedly connected at equal intervals between the two belts. The conveyor belt is fitted around the frame and is a mesh belt.

[0011] Furthermore, the rollers are rotatably connected between the inner walls of the two sides of the material box, and a torsion spring is fixedly connected between the rollers and the material box. Several rollers are equidistantly distributed at the top inner side of the conveyor belt, and the swing arm is made of rubber.

[0012] Furthermore, the top of both sides of the material box is provided with a feed port and a discharge port respectively. The material box is fixedly connected to a feed plate at the feed port and a discharge plate at the discharge port. Both the feed plate and the discharge plate are inclined.

[0013] Furthermore, a mesh panel is fixedly connected to the top of the material box.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This device generates a stable airflow in the material box using a fan, ensuring that the air pressure inside the box is lower than the air pressure at the top. This pressure difference creates a downward airflow on the conveyor belt, which assists in the dewatering process as the ore is transported. Simultaneously, the airflow in the material box blows the blades, causing the rollers to deflect. The rollers then return to their original position under the force of the torsion springs and the gravity of the blades. This repeated action causes the swing arm to continuously strike the conveyor belt, inducing vibration. This not only helps to shake off external moisture from the ore but also ensures sufficient contact between the ore and the airflow, thereby improving the dewatering efficiency. Furthermore, this device allows for continuous ore dewatering via the conveyor belt, further maintaining the high efficiency of this process.

[0016] 2. The equidistant arrangement of rollers at the top of the conveyor belt can provide support, so the conveyor belt can stably transport ore and avoid the weight of the ore from pressing on the conveyor belt, causing it to deform or dent, which would affect the smooth and stable operation of the ore dewatering process.

[0017] 3. By setting up a mesh plate, the mesh plate can not only protect the ore above the conveyor belt and prevent it from splashing due to the vibration of the conveyor belt, but also filter the airflow from top to bottom on the conveyor belt to prevent the airflow from carrying too many external impurities, thus protecting the ore.

[0025] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the utility model.

[0026] Example 1

[0027] See attached document Figures 1-4 This application provides an ore dewatering device, including a material box 1. The material box 1 is equipped with a transmission mechanism and a vibration mechanism. Several air inlets and outlets are opened on both sides of the material box 1. Fans 2 are fixedly connected to the air inlets and outlets of the material box 1. The fans 2 are used to generate airflow in the material box 1. This airflow includes horizontal airflow generated by the operation of the fans and downward airflow generated by the pressure difference between the inside and outside of the material box 1 caused by the gas flow. By using this downward airflow to act on the surface of the ore, it can assist in its dewatering. The lumpy ore does not adhere very tightly to each other, so this measure effectively helps in its dewatering. The transmission mechanism includes a conveyor belt 4, which is used to transport the ore in the airflow. The vibration mechanism includes several rollers 14. Blades 15 are fixedly connected to the bottom end of the rollers 14. Several swing arms 16 are fixedly connected to the leeward side of the rollers 14. The blades 15 drive the swing arms 16 to strike the conveyor belt 4 through the airflow to induce vibration.

[0028] Preferably, a rotating shaft 8 is rotatably connected to one end of the inner wall of one side of the material box 1, and a circular through hole is opened at one end of the other side of the material box 1. One end of the rotating shaft 8 extends to the outside of the material box 1 through the circular through hole. A housing 6 is fixedly connected to the outer wall of the material box 1 outside the circular through hole. A motor 7 is fixedly connected inside the housing 6, and the output shaft of the motor 7 is fixedly connected to the rotating shaft 8. A connecting shaft 9 is rotatably connected between the inner walls of the two sides of the material box 1 on the side away from the rotating shaft 8. Driven wheels 10 are connected to both ends of the rod of the connecting shaft 9 by keys. Driven wheels 13 are connected to both ends of the rod of the rotating shaft 8 inside the material box 1 by keys. The two driven wheels 13 correspond to the two driven wheels 10 respectively. The driving wheel 13 and the driven wheel 10 on the left and right are fitted with the same belt 12. Several skeletons 11 are fixedly connected at equal intervals between the two belts 12. The conveyor belt 4 is fitted on the outside of the skeleton 11. The conveyor belt 4 is a mesh belt. The conveyor belt 4 in this form has better air permeability, which is conducive to the dehydration of ore.

[0029] When using this device to dewater ore, the motor 7 and all the fans 2 can be started. The motor 7 can drive the two drive wheels 13 to rotate through the rotating shaft 8. Under the support of the driven wheel 10, the rotation of the drive wheel 13 can drive the belt 12 to run, and the two belts 12 can drive the conveyor belt 4 to run through the frame 11.

[0030] The fans 2 located at both ends of the material box 1 can respectively perform the functions of ventilation and exhaust when running. Therefore, the operation of the fans 2 can generate a stable airflow in the material box 1. This airflow can make the pressure inside the material box 1 less than the pressure on its outer top. Therefore, this pressure difference can be used to generate an airflow from top to bottom at the conveyor belt 4.

[0031] Preferably, the roller 14 is rotatably connected between the inner walls of the two sides of the material box 1, and a torsion spring 17 is fixedly connected between the roller 14 and the material box 1. Several rollers 14 are equidistantly distributed at the inner top of the conveyor belt 4, and the swing arm 16 is made of rubber.

[0032] On the other hand, the airflow flowing in the material box 1 can also blow the blades 15 to deflect the roller 14. Then, under the elastic force of the swing arm 16 and the torsion spring 17 and the gravity of the blades 15, the roller 14 will return to its original state. Therefore, in this process, the roller 14 will drive the swing arm 16 to repeatedly strike the conveyor belt 4 to cause it to vibrate.

[0033] Preferably, the top of the two sides of the material box 1 are respectively provided with a feed inlet and a discharge outlet. The material box 1 is fixedly connected to the feed inlet with a feed plate 5 and the material box 1 is fixedly connected to the discharge outlet with a discharge plate 3. Both the feed plate 5 and the discharge plate 3 are inclined.

[0034] After that, the ore to be dehydrated can be fed from the feed plate 5 onto the conveyor belt 4. The operation of the conveyor belt 4 can transport the ore, and during the transport process, the airflow from top to bottom can act on the surface of the ore to assist its dehydration process. At the same time, the vibration of the conveyor belt 4 can also shake the ore, so it can not only help shake off the moisture on the outside of the ore, but also ensure that the ore is in full contact with the airflow, thereby ensuring the efficiency of the device in dehydrating the ore.

[0035] After the ore has been dehydrated, the continuous operation of the conveyor belt 4 can move the ore to the discharge plate 3. Therefore, it is only necessary to place a container at the bottom of the discharge plate 3 to collect the dehydrated ore.

[0036] Example 2

[0037] See attached document Figure 5 This application provides an ore dewatering device. Compared with Embodiment 1, in order to protect the ore, a mesh plate 18 is fixedly connected to the top of the material box 1.

[0038] When using the airflow on the surface of the conveyor belt 4 to assist in the dehydration of the ore, the screen plate 18 can filter the airflow flowing from top to bottom, thus preventing the airflow from carrying too many external impurities into the ore; in addition, the screen plate 18 can cover the top of the conveyor belt 4, thus preventing the vibration of the conveyor belt 4 from causing the ore to splash, thereby providing a protective effect for the ore.

[0039] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
