Description

Technical Field

[0001] This utility model relates to the field of mineral washing equipment technology, and in particular to a countercurrent centrifugal continuous washing device for nephrite salt ore. Background Technology

[0002] Salt mines, especially jadeite salt mines, typically contain mud, sand, impurities, and soluble salts after mining. To obtain high-purity products, thorough washing is necessary. Currently, mechanized washing equipment is widely used in industry to clean the minerals.

[0003] Existing washing technologies mainly utilize rotating drums or agitated tanks to clean salt mines. The basic principle is to use mechanical stirring or tumbling to ensure full contact between the material and the washing liquid, thereby removing impurities. However, these traditional washing devices have revealed many shortcomings in practical applications. On the one hand, many washing equipment adopt a batch operation mode, with the washing process and subsequent dehydration process usually carried out independently. The material needs to be transferred multiple times between processes, resulting in low production efficiency, increased labor costs, and difficulty in achieving continuous and automated production lines. On the other hand, simple mechanical stirring or tumbling washing methods are not effective in removing fine particles or stubborn impurities adhering to the surface of minerals. Especially for nephrite salt ore, which requires high purity, the washing effect is difficult to meet the strict product quality requirements, resulting in impurity residue and affecting the purity of the final product. In addition, the washed material often contains a large amount of water, and the subsequent dehydration process directly affects production energy consumption and material drying costs. How to achieve efficient and rapid solid-liquid separation is a key issue. Traditional solutions have the drawbacks of complex structure, high energy consumption, or low dehydration efficiency in achieving a close connection between washing and dehydration. They cannot provide a comprehensive solution that is compact in structure, stable in operation, has good washing and dehydration effects, and can achieve continuous operation.

[0004] Therefore, this utility model proposes a countercurrent centrifugal continuous washing device for jadeite salt mine to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing technology of washing and dewatering equipment for jadeite salt mines, such as low production efficiency due to the separation of washing and dewatering processes, difficulty in achieving automated continuous operation, and low cleanliness due to the single tumbling washing method, this utility model aims to provide a countercurrent centrifugal continuous washing device for jadeite salt mines with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a countercurrent centrifugal continuous washing device for jadeite salt mine, including: a support frame, a washing mechanism, a screening mechanism, a first motor, a rotating shaft, rollers, a baffle, a water injection plate, a second motor, centrifugal blades, and a hydraulic push rod.

[0007] The washing mechanism is equipped with centrifugal blades driven independently by two motors, forming a combined motion of tank rotation and internal stirring. At the same time, the washing mechanism can achieve overall tilting discharge through the drive of hydraulic push rods.

[0008] Furthermore, the motor drives the washing mechanism to rotate via friction transmission through a rotating shaft and rollers. The rotating washing mechanism is supported by the baffle. The screening mechanism is located below the discharge end of the washing mechanism. Through this integrated structure of washing, discharge, and dewatering, continuous automation of material processing is achieved.

[0009] Preferably, the screening mechanism includes a fixed frame for receiving materials, a screen installed inside the fixed frame, and a vibrator fixedly connected to the right end of the fixed frame, the vibrator being used to drive the fixed frame and the screen to vibrate.

[0010] Preferably, the screening mechanism further includes a fixed frame fixedly connected to the right side inside the support frame, and buffer frames are fixedly connected to the four top corners of the fixed frame. The fixed frame is connected to the top of the fixed frame through the buffer frames.

[0011] Preferably, the left end of the fixed frame is rotatably connected to an arc-shaped rod, and the other end of the arc-shaped rod cooperates with the support frame or the washing mechanism to adjust the tilt angle of the fixed frame in coordination when the hydraulic push rod pushes the washing mechanism.

[0012] Preferably, the arc-shaped rod is provided with bolts, which are used to rotate and fix the arc-shaped rod to lock the tilt angle of the fixing frame.

[0013] Preferably, the centrifuge tank is connected to the left end of the screening tank and is used for preliminary screening and washing of the material. The processed material then enters the screening tank for deep washing.

[0014] Preferably, one end of the hydraulic push rod is rotatably connected to the left end of the support frame, and the other end acts on the bottom of the washing mechanism, so as to achieve the overall tilting of the washing mechanism by extension and retraction.

[0015] Preferably, the centrifugal blades rotate inside the centrifuge tank under the drive of motor two, which is used to agitate the material entering the centrifuge tank and the washing liquid injected through the water injection plate.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem in the prior art that the washing and dewatering processes are separated, the materials need to be transferred multiple times, and continuous automated production cannot be achieved by setting up a washing mechanism that can be driven to tilt by a hydraulic push rod and connecting the vibrating screening mechanism to the discharge end of the washing mechanism. It achieves the effect of integrating the washing and dewatering processes, realizing automatic material transfer and continuous processing, and significantly improving production efficiency.

[0018] 2. This utility model solves the problem in the prior art of drum washing that relies solely on the tumbling of the tank, resulting in a single force and insufficient mixing of materials and washing liquid, leading to low washing cleanliness, by setting centrifugal blades driven by an independent motor to rotate high speed inside the rotating washing tank. It achieves the effect of using the tank's rotation and the internal centrifugal blades to form a compound powerful flush, cleaning materials in all directions without dead angles, and significantly improving washing effect and efficiency.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example:

[0029] Please refer to Figures 1 to 6 This utility model provides a countercurrent centrifugal continuous washing device for alumina salt ore, which aims to solve the problem in the prior art that the washing mechanism 2 and the dewatering mechanism of the alumina salt ore washing device are structurally separated, making it difficult to achieve continuous and automatic material transfer.

[0030] Please refer to Figure 1 , Figure 2 and Figure 3 A countercurrent centrifugal continuous washing device for nephrite salt ore includes a support frame 1, and a washing mechanism 2 and a screening mechanism 3 installed on the support frame 1. The support frame 1 serves as the mounting base for the entire device, providing stable installation and support for the washing mechanism 2 and the screening mechanism 3. The washing mechanism 2 is used to centrifugally wash the nephrite salt ore, and the screening mechanism 3 is installed at the discharge end of the washing mechanism 2 and is used to vibrate and dehydrate the washed nephrite salt ore.

[0031] Please refer to Figure 1 , Figure 2 and Figure 4 Motor 201 is fixedly connected to the top left side of support frame 1. The output end of motor 201 is fixedly connected to shaft 202. Rollers 203 are fixedly connected to both ends of shaft 202. Rollers 203 have wear-resistant elastic outer surfaces. Rollers 203 are rotatably connected to shaft 202 through bearings to provide driving force for centrifuge tank 207 and screening tank 208. Baffles 210 are installed on the front and rear sides of the middle part of support frame 1. Baffles 210 have arc-shaped upper surfaces. Baffles 210 are used to rotate and support centrifuge tank 207 and screening tank 208. At the same time, the outer peripheral walls of centrifuge tank 207 and screening tank 208 are adapted to the outer surface shape of roller 203 and the arc-shaped upper surface shape of baffle 210. In the assembled state, the roller 203 abuts against the outer peripheral walls of the centrifuge tank 207 and the screening tank 208 and drives the centrifuge tank 207 and the screening tank 208 to rotate synchronously through friction transmission. The outer peripheral walls of the centrifuge tank 207 and the screening tank 208 simultaneously rotate against the arc-shaped upper surface of the baffle 210. This multi-point support and friction-driven structure ensures the stability and continuity of the centrifuge tank 207 and the screening tank 208 during the rotation process, effectively improving the washing effect of the nephrite salt ore.

[0032] As another preferred embodiment, in order to provide stable support for the vibration of the screening mechanism 3 and reduce the wear caused by vibration, please refer to... Figure 3 and Figure 4 The screening mechanism 3 also includes a fixed frame 301 fixedly connected to the right side of the support frame 1. Buffer frames 302 are fixedly connected to the four corners of the top of the fixed frame 301. The buffer frames 302 are made of elastic material. The fixed frame 304 is connected to the top of the buffer frame 302 through the four bottom corners. When the vibrator 303 is working, the buffer frame 302 can absorb and reduce vibration energy, protect the main structure of the device, and increase the screening frequency.

[0033] As another preferred embodiment, in order to flexibly adjust the tilt angle of the screening mechanism 3 according to the material characteristics and dewatering requirements, please refer to... Figure 5 An arc-shaped rod 306 is rotatably connected to the left end of the fixed frame 304. The other end of the arc-shaped rod 306 is rotatably connected to the corresponding position of the support frame 1. Through the rotatable connection with the fixed frame 304, the arc-shaped rod 306 can cooperate with and adjust the tilt angle of the fixed frame 304 when the hydraulic push rod 206 pushes the washing mechanism 2 to tilt, so as to adapt to the discharge and dewatering requirements under different working conditions.

[0034] As another preferred embodiment, in order to accurately lock the tilt angle of the screening mechanism 3, please refer to... Figure 5 The arc-shaped rod 306 is provided with a bolt 307. The bolt 307 passes through the preset hole of the arc-shaped rod 306 and is screwed into the threaded hole on the fixed frame 304 or the support frame 1. After the bolt 307 is tightened, the arc-shaped rod 306 can be rotated and fixed, thereby reliably locking the tilt angle of the fixed frame 304 and ensuring the stability of the screening and dewatering process.

[0035] In another preferred embodiment, to ensure the continuous washing and processing effect of the nephrite salt ore, the centrifuge tank 207 is connected to the left end of the screening tank 208. This connection method allows the material that has been pre-treated by the centrifuge tank 207 to smoothly and continuously enter the screening tank 208. The centrifuge tank 207 is mainly used for preliminary mixing and washing of the material and to complete the preliminary screening of larger particles. The processed material then enters the screening tank 208 for more detailed washing, ensuring the continuity and efficiency of the entire washing process.

[0036] As another preferred embodiment, in order to realize the tilting and discharging function of the washing mechanism 2, please refer to... Figure 4One end of the hydraulic push rod 206 is rotatably connected to the left end of the support frame 1 via a pin, and the other end of the hydraulic push rod 206 acts on the bottom of the washing mechanism 2 via a detachable connector. Through the extension and retraction of the hydraulic cylinder, the contact point between the washing mechanism 2 and the baffle 210 can be used as the fulcrum to realize the overall tilting of the washing mechanism 2, thereby facilitating the discharge of materials from the washing mechanism 2 into the screening mechanism 3.

[0037] In another preferred embodiment, in order to enhance the washing effect inside the centrifuge tank 207, the centrifuge blade 209 rotates inside the centrifuge tank 207 under the drive of the motor 205. The centrifuge blade 209 has multiple blades, and the high-speed rotation of the centrifuge blade 209 can generate strong agitation and centrifugal force, so that the jasper mineral material entering the centrifuge tank 207 is fully mixed with the washing liquid injected through the water injection plate 204, which accelerates the dissolution and separation of dirt and improves washing efficiency.

[0038] Working principle: When the agate salt mineral material is fed into the centrifuge tank 207 of the washing mechanism 2, the motor 1 201 starts and drives the roller 203 to rotate through the rotating shaft 202. The roller 203 then drives the centrifuge tank 207 and the screening tank 208 to rotate synchronously around the central axis through friction. At the same time, the washing liquid is injected into the centrifuge tank 207 through the water injection plate 204. The motor 205 drives the centrifugal blades 209 inside the centrifuge tank 207 to rotate at high speed. Under the dual action of the tank's rotation and the stirring of the centrifugal blades 209, the material and the washing liquid are fully mixed, rinsed and separated in the centrifuge tank 207 to achieve efficient washing. The washed material continuously enters the screening tank 208 for secondary washing under the action of the spiral guide plate.

[0039] After washing is completed, the hydraulic push rod 206 extends, tilting the entire washing mechanism 2 towards the screening mechanism 3. The material automatically slides onto the screen 305 of the screening mechanism 3. At this time, the vibrator 303 starts, and the high-frequency vibration generated causes the water on the material to be quickly removed, completing the dehydration operation. Through this structural cooperation and automated control of the washing mechanism 2 and the screening mechanism 3, this utility model solves the problem of the separation of washing and dehydration processes in the prior art and the inability to continuously automate the process, significantly improving production efficiency.
