Description

Technical Field

[0001] This invention relates to the field of tailings recovery technology, and in particular to a tailings recovery device for a ore washing machine. Background Technology

[0002] Ore washing machines are large-scale equipment used in ferrous and non-ferrous metallurgical mines, steel mills, metallurgical plants, chemical plants, and building materials industries to clean ores. They are divided into two main categories: spiral ore washing machines and cylindrical ore washing machines. Currently, common ore washing machines cannot directly screen and separate sand and gravel according to their specifications during sand and gravel washing. They can only concentrate the sand and gravel together for subsequent screening and separation, resulting in reduced practicality and functionality, and failing to meet usage requirements.

[0003] Chinese utility model patent application number CN202122700607.9 discloses a tailings separation and recovery device for a ore washing machine. This prior art utilizes a conveyor screen to screen sand and gravel. After the conveyor screen filters the ore, fine sand and gravel fall to the bottom of the machine body. The slope at the bottom concentrates the fine sand and gravel, which then enters the discharge port. The drive motor is then started, and a linked guide plate is activated to discharge the material, making the process convenient and quick. However, in this prior art, the tailings that cannot be further processed also have many uses, resulting in waste. Summary of the Invention

[0004] To address the aforementioned technical problems, the technical solution proposed in this invention can solve the problem of low tailings recovery efficiency in ore washing machines. It is highly practical and can refine and screen tailings particles multiple times to meet recovery standards.

[0005] The technical solution used in this invention is as follows: a tailings recovery device for a ore washing machine, comprising a base, a water tank at the bottom of the base, and a filter conveyor belt movably mounted above the water tank; a screening component for screening ore particles is fixedly mounted at one end of the base, a screening plate is fixedly mounted on the screening component, and a push rod is movably mounted on the screening component for pushing away ore particles remaining on the screening plate; a transport component for conveying ore particles is mounted on the screening component; a refining component for refining mineral particles is mounted on the side of the base, and the ore particles are transported to the refining component for refining treatment via the transport component; a drying component for air-drying ore is mounted at the other end of the base. The unit includes a drying component with a rotating fan and a heater. Several vibrating rods are rotatably mounted inside the filter conveyor belt, their shafts making contact with the belt. Rotation of the vibrating rods causes the conveyor belt to vibrate. A cleaning component is movably mounted inside the water tank. This component includes a sliding plate installed in the tank, a scraper movably mounted on the plate, and an electromagnet controlling the scraper's extension and retraction. Two electromagnet triggers are mounted on the scraper. Limit switches are located at both ends of the tank. When the electromagnet contacts the triggers, it activates the electromagnet to control the scraper's extension and retraction.

[0006] Furthermore, when the water filter conveyor belt is driven, the drying component, the shaking rod, and the screening component are simultaneously linked with the water filter conveyor belt; when the cleaning component is driven, the refining component is linked with the cleaning component.

[0007] Furthermore, one end of the vibrating rod is fixedly connected to a vibrating rod gear, and the vibrating rod gears on each vibrating rod mesh with each other.

[0008] Furthermore, the drying component includes a mounting base, a fan is rotatably mounted on the mounting base, a fan gear is fixedly connected to the fan, a drive shaft is rotatably mounted on the mounting base, a drive shaft gear is fixedly connected to the drive shaft, and the drive shaft gear meshes with the fan gear.

[0009] Furthermore, the screening component includes a screening box, a screening plate fixedly installed on the screening box, inclined plates fixedly connected to both sides of the screening box, a conveying component including a conveying shaft rotatably installed on the screening box, ore particles sliding down the inclined plates into the conveying shaft, the screening plate slidably installed on the screening box, a connecting rod rotatably installed on one end of the push rod, and the screening component also includes a crank turntable rotatably installed on the base, the crank turntable being rotatably connected to one end of the connecting rod.

[0010] Furthermore, the refining component includes a refining box fixedly disposed on the side of the base, and a plurality of pulverizing shafts are rotatably installed inside the refining box. One end of each pulverizing shaft is fixedly connected to a pulverizing shaft gear, and the pulverizing shaft gears on each pulverizing shaft mesh with each other.

[0011] Furthermore, the cleaning component also includes a lead screw rotatably mounted on the base, the lead screw and the slide plate forming a helical pair.

[0012] The advantages of this invention compared with the prior art are: (1) the drying component can quickly dry the ore particles; (2) the rotation of the shaking rod can shake the water conveyor belt, which helps to shake off the water on the water conveyor belt and accelerate the drying; (3) the cleaning component can remove impurities and water in the water tank, reducing the subsequent cleaning work.

Detailed Implementation

[0019] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0020] like Figure 1 and Figure 2 As shown, a collection box 101 is provided on one end of the base 1, a drive motor 102 is fixedly provided on the side of the base 1, a water tank is provided on the base 1, and a water filter conveyor belt 103 is movably provided above the water tank. The water filter conveyor belt 103 is provided with water filter holes. The output shaft of the drive motor 102 is fixedly connected to a roller at one end of the water filter conveyor belt 103 to drive the water filter conveyor belt 103 to move. A belt drive structure 104 is also provided on the output shaft of the drive motor 102. Several vibrating rods 105 are rotatably provided on the inner side of the water filter conveyor belt 103. One end of each vibrating rod 105 is fixedly connected to a vibrating rod gear 106. Every two adjacent vibrating rod gears 106 mesh with each other. The belt drive structure 104 is connected to one end of one of the vibrating rods 105. When the drive motor 102 drives the water filter conveyor belt 103, the vibrating rod 105 is also driven.

[0021] For the drying component 2, the mounting base 201 is fixedly mounted on one end of the base 1, the fan 202 is rotatably mounted on the mounting base 201, the fan gear 203 is fixedly connected to the fan 202, the drive shaft 204 is rotatably mounted on the mounting base 201, the drive shaft gear 205 is fixedly connected to the drive shaft 204, the drive shaft gear 205 meshes with the fan gear 203, and the mounting base 201 is provided with a heater for heating air; one end of the drive shaft 204 is connected to the roller at one end of the water filter conveyor belt 103 through a belt drive structure 107, and the fan 202 is also driven when the water filter conveyor belt 103 is driven.

[0022] like Figure 1 , Figure 2 and Figure 5 As shown, for screening component 3, screening box 301 is fixedly installed at the other end of base 1. Screening box 301 is provided with a feed inlet. Screening plate 307 is fixedly connected inside screening box 301. Screening plate 307 has screening holes. Inclined plates 308 are fixedly connected to both sides of screening plate 307. Push rod 306 is slidably installed inside screening box 301. Connecting rod 303 is rotatably installed on one end of push rod 306. Crank turntable 305 is rotatably installed on base 1. Crank turntable 305 is rotatably connected to one end of connecting rod 303. Screening box 301 is provided with a transport mechanism. The component, for the transport component, includes two conveyor shafts 309 rotatably mounted on the screening box 301. The two conveyor shafts 309 are connected by a belt drive structure 302. One of the conveyor shafts 309 is connected to a roller at one end of the filter conveyor belt 103 by a belt drive structure 108, and the other conveyor shaft 309 is connected to a crank turntable 305 by a belt drive structure 304. When the filter conveyor belt 103 is driven, the two conveyor shafts 309 are driven, which in turn drives the crank turntable 305, enabling the push rod 306 to reciprocate.

[0023] For the refining component 4, the refining box 401 is fixedly installed on the side of the base 1. Several grinding shafts 402 are rotatably installed inside the refining box 401. One end of the grinding shaft 402 is fixedly connected to a grinding shaft gear 403, and the grinding shaft gears 403 on each grinding shaft 402 mesh with each other.

[0024] like Figure 3 and Figure 4 As shown, for the cleaning component 5, the lead screw motor 501 is fixedly installed at one end of the base 1, the output shaft of the lead screw motor 501 is fixedly connected to the lead screw 503, the lead screw 503 is rotatably installed on the base 1, and a belt drive structure 6 502 is connected to the output shaft of the lead screw motor 501. One end of the belt drive structure 6 502 is connected to one of the agitation shafts 402. When the lead screw motor 501 drives the lead screw 503, the agitation shaft 402 is driven.

[0025] The slide plate 504 is slidably installed in the water tank. The slide plate 504 and the lead screw 503 form a helical pair. A scraper 505 is movably installed on the slide plate 504. An electromagnet 506 is provided on the slide plate 504 to control the extension and retraction of the scraper 505. Two electromagnet triggers 507 are provided on the scraper 505. Limit switches 508 are provided at both ends of the water tank. When the limit switch 508 contacts the electromagnet triggers 507, the electromagnet 506 is triggered to control the extension and retraction of the scraper 505. The belt drive structure in the above-mentioned case consists of two pulleys and a belt.

[0026] In the execution of this invention, ore particles enter the screening box 301 and fall onto the screening plate 307. Ore particles that can pass through the screening holes on the screening plate 307 fall onto the water filter conveyor belt 103. When the water filter conveyor belt 103 is driven by the drive motor 102, several vibrating rods 105 rotate under the connection of belt drive structure one 104. At the same time, under the connection of belt drive structure three 108, belt drive structure four 302, and belt drive structure five 304, the conveyor shaft 309 rotates, the crank turntable 305 rotates, and under the connection of the connecting rod 303, the push rod 306 slides repeatedly to push the particles remaining on the screening plate 307 to the conveyor shafts 309 on both sides. The rotation of the conveyor shafts 309 transports the ore particles into the refining box 401.

[0027] When the vibrating rod 105 rotates, its body exerts a squeezing effect on the filter conveyor belt 103, causing the filter conveyor belt 103 to vibrate while transporting ore. This helps to shake off the water on the filter conveyor belt 103. When driving the filter conveyor belt 103, the drive shaft 204 rotates under the connection of the belt drive structure 107. Under the meshing of gears, the fan 202 rotates, and under the action of the heater, the fan 202 generates hot air to dry the ore particles on the filter conveyor belt 103. The relevant operators can set the corresponding transmission ratio of the gear drive and belt drive so that the fan 202 can rotate quickly when driving the filter conveyor belt 103 to achieve the drying effect.

[0028] When the water tank needs cleaning, the lead screw motor 501 drives the lead screw 503, causing the slide plate 504 to move. This pushes out the water and impurities falling from the filter holes on the filter conveyor belt 103. During this process, the electromagnet 506 controls the scraper 505 to extend, so that the end of the scraper 505 facing the bottom of the water tank contacts the bottom of the water tank. When one of the electromagnet triggers 507 on the scraper 505 contacts the limit switch 508 at one end of the water tank, the electromagnet 506 controls the scraper 505 to retract, and the slide plate 504... 04. The return motion is performed so that the bottom of the scraper 505 does not contact the bottom of the water tank during the return stroke, preventing water and impurity particles from being pushed back. Another electromagnet trigger 507 on the scraper 505 contacts the limit switch 508 at the other end of the water tank. The electromagnet 506 controls the scraper 505 to extend, and this is repeated. When the lead screw motor 501 drives the lead screw 503, under the connection of the belt drive structure 502, several crushing shafts 402 are driven to crush and refine the ore particles transported by the conveyor shaft 309 for further screening.

[0029] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the protection scope of this invention.
