Description

Technical Field

[0001] This utility model relates to the field of phosphate rock desliming technology, and in particular to a desliming device for phosphate rock processing. Background Technology

[0002] Phosphate rock, a general term for economically viable phosphate minerals, is a key chemical mineral raw material. It is not only a core raw material for the production of phosphate fertilizers but can also be used to prepare yellow phosphorus, phosphoric acid, phosphates, and various phosphate products. However, after mining, phosphate ore requires scrubbing and desliming equipment to remove the mud and water adhering to its surface. Current technical solutions suffer from cumbersome mechanisms; their auger components lack ore scrubbing capabilities, and the water-bearing ore inside the tank, after being transported by the auger, still requires secondary cleaning by a water spray mechanism, resulting in low overall cleaning efficiency.

[0003] To address the aforementioned problems, a scrubbing and desliming device has emerged. For example, Chinese Utility Model Patent CN219817274U discloses a scrubbing and desliming device for phosphate rock beneficiation. This device includes a support unit and a fixed cylinder mounted on the support unit. The fixed cylinder comprises an open-fronted outer shell with a tilted design, higher at the front and lower at the rear. A washing cylinder is rotatably connected inside the outer shell, and a feeding and washing device is located at the central axis of the washing cylinder. This phosphate rock beneficiation scrubbing and desliming device utilizes a rotating washing cylinder inside the outer shell. A motor drives the entire washing cylinder to rotate, and the phosphate ore is transported forward by the spiral blades inside the washing cylinder. During transport, the phosphate ore is subjected to centrifugal force and rotates along with the washing cylinder, then falls under gravity. This causes the phosphate ore to come into contact and rub against each other during transport. Combined with the continuous spraying of cleaning water into the washing cylinder by nozzles, the overall scrubbing and desliming efficiency of the equipment is improved. However, the gap between the outer shell 10 and the cleaning shell 20 of the above-mentioned device has no flow guiding structure. The mud and water rely on a fixed tilt angle to flow naturally to the mud discharge trough 101, which easily accumulates in the gap and may even flow back to the cleaning shell 20. Therefore, a desliming device for phosphate rock processing is proposed to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a desliming device for phosphate rock processing.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses a desliming device for phosphate rock processing, comprising a shell, a desliming mechanism, and a feeding rack. The desliming mechanism is disposed inside the shell, and the feeding rack is disposed on the shell and extends into the desliming mechanism. The shell has an outlet for discharging the cleaned phosphate rock and a mud discharge port. The device also includes multiple guide plates, a filter screen, and a mud discharge pump. The multiple guide plates are spaced apart on the inner side wall of the shell, with one end facing the mud discharge port. The filter screen is disposed on the guide plates and located on one side of the mud discharge port to intercept large particles of impurities and prevent the mud discharge port from clogging. The mud discharge pump is located at the bottom of the shell, and its suction port is connected to the mud discharge port.

[0006] As a preferred embodiment of this utility model, the desliming mechanism includes a motor, a desliming cylinder, auger blades, and a cleaning assembly. The motor is mounted on the housing, and its output shaft is coaxially connected to the desliming cylinder. Annular sliders are provided at both ends of the desliming cylinder. Annular grooves adapted to the annular sliders are provided on the inner wall of the housing. The desliming cylinder rotates within the housing. The auger blades are located on the inner wall of the desliming cylinder. Desliming holes are provided on the desliming cylinder. The cleaning assembly is mounted on the feeding frame to clean the phosphate rock inside the desliming cylinder.

[0007] As a preferred technical solution of this utility model, the cleaning component includes a water pipe and a plurality of first nozzles. The water pipe is located at the bottom end of the feeding frame, and one end of the water pipe extends into the desludge cylinder. The first nozzles are located on the water pipe and are connected to the desludge cylinder. An electric valve is provided on the water pipe.

[0008] As a preferred technical solution of this utility model, it also includes a backwashing assembly, which includes multiple backwashing pipes and multiple second nozzles. The backwashing pipes are located at the bottom of the feeding frame and are connected to the water pipe through corresponding connecting pipes. The connecting pipes are equipped with solenoid valves. The second nozzles are located on the backwashing pipes and are located inside the desludge dewatering cylinder and face different directions.

[0009] As a preferred embodiment of this utility model, it also includes a pressure sensor, which is disposed on the housing, and both the pressure sensor and the solenoid valve are electrically connected to the controller.

[0010] As a preferred embodiment of this utility model, the side end of the housing is fixed with multiple mounting plates, and each mounting plate is provided with multiple support legs.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The phosphate ore is placed on the feeding rack and falls into the desliming mechanism under gravity. The desliming mechanism cleans the phosphate ore, and the resulting mud and water fall onto the inner wall of the shell. The flow of the mud and water is accelerated by the guide plate. The mud and water are guided through the filter screen to the mud discharge port and finally discharged from the mud discharge port. The mud discharge pump provides the power for active mud discharge, ensuring that the mud and water are discharged quickly and avoiding blockage of the mud discharge port. The cleaned phosphate ore is discharged from the discharge port. The filter screen can intercept large particles of impurities and prevent blockage of the mud discharge port. It is also fixed to the guide plate with quick-release screws for easy replacement and cleaning.

[0012] 2. Opening the electric valve will spray clean water from multiple nozzles onto the phosphate ore in the desliming cylinder, rinsing its surface. The phosphate ore falls from the feeding frame into the desliming cylinder. Starting the motor transmits its output torque to the desliming cylinder via a coupling. The rotation of the desliming cylinder throws the mud and water from the phosphate ore through the desliming holes onto the inner wall of the casing. The auger blades transport the phosphate ore from the rear end of the desliming cylinder to the discharge port at the front end. 3. The pressure sensor can detect the pressure of mud and water between the shell and the desliming cylinder. When the data detected by the pressure sensor is greater than the threshold set by the controller, the controller will control the solenoid valve to open, allowing clean water to spray out from the second nozzle to flush the desliming hole.

[0014] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0015] Example 1: Figure 1-4 This utility model provides a desliming device for phosphate rock processing, including a shell 1, a desliming mechanism, and a feeding rack 2.

The shell 1 has an outlet 3 for discharging the cleaned phosphate rock and a mud discharge port 4. It also includes multiple guide plates 5, a filter screen 6, and a mud discharge pump 7. The multiple guide plates 5 are spaced apart on the inner side wall of the shell 1, with one end facing the mud discharge port 4. The filter screen 6 is located on the guide plates 5 and is located on one side of the mud discharge port 4 to intercept large particles of impurities and prevent the mud discharge port 4 from being blocked. The mud discharge pump 7 is located at the bottom of the shell 1, and its suction port is connected to the mud discharge port 4.

[0016] In this embodiment, phosphate ore is placed on the feeding rack 2. Under the action of gravity, the phosphate ore will fall into the desliming mechanism. The desliming mechanism can clean the phosphate ore. The mud and water generated after cleaning will fall onto the inner wall of the shell 1. The flow of the mud and water is accelerated by the guide plate 5. The mud and water are introduced into the mud discharge port 4 through the filter screen 6 and finally discharged from the mud discharge port 4. The mud discharge pump 7 can provide the power for active mud discharge to ensure that the mud and water are discharged quickly and avoid the mud discharge port 4 from being blocked. The cleaned phosphate ore will be discharged from the discharge port 3. The filter screen 6 can intercept large particles of impurities to prevent the mud discharge port 4 from being blocked. It is also fixed to the guide plate 5 with quick-release screws for easy replacement and cleaning.

[0017] Example 2: Preferably, as another embodiment of this utility model, in Figure 1 Based on the embodiment shown, the desliming mechanism includes a motor 81, a desliming cylinder 82, an auger blade 83, and a cleaning assembly. The motor 81 is mounted on the housing 1, and its output shaft is coaxially connected to the desliming cylinder 82. The two ends of the desliming cylinder 82 are provided with annular sliders 84. The inner sidewall of the housing 1 is provided with annular grooves that are adapted to the annular sliders 84. The desliming cylinder 82 rotates inside the housing 1. The auger blade 83 is mounted on the inner sidewall of the desliming cylinder 82. The desliming cylinder 82 is provided with desliming holes 85. The cleaning assembly is mounted on the feeding rack 2 to clean the phosphate rock inside the desliming cylinder 82.

[0018] In this embodiment, as one implementation method, phosphate ore falls from the feeding rack 2 into the desliming cylinder 82. The motor 81 is started, and the output torque of the motor 81 is transmitted to the desliming cylinder 82 through the coupling. The rotation of the desliming cylinder 82 can throw the mud and water on the phosphate ore out from the desliming hole 85 to the inner wall of the shell 1. The auger blades 83 can transport the phosphate ore from the rear end of the desliming cylinder 82 to the discharge port 4 at its front end for discharge.

[0019] Specifically, the cleaning assembly includes a water pipe 91 and multiple first nozzles 92. The water pipe 91 is located at the bottom of the feeding frame 2, and one end of it extends into the desliming cylinder 82. The first nozzles 92 are located on the water pipe 91 and are located inside the desliming cylinder 82. An electric valve 93 is provided on the water pipe 91.

[0020] Connect the water pipe 91 to an external water source and open the electric valve 93 to spray clean water from multiple first nozzles 92 onto the phosphate rock in the desliming cylinder 82, which can wash the surface of the phosphate rock.

[0021] Example 3: Preferably, as another embodiment of this utility model, in Figure 1 Based on the embodiment shown, a backwashing assembly is also included. The backwashing assembly includes multiple backwashing pipes 101 and multiple second nozzles 102. The backwashing pipes 101 are located at the bottom of the feeding frame 2 and are connected to the water pipe 91 through corresponding connecting pipes 103. A solenoid valve 104 is provided on the connecting pipe 103. The second nozzles 102 are located on the backwashing pipes 101 and are located inside the desludge dewatering cylinder 82 and facing different directions.

[0022] In this embodiment, as one implementation method, when the solenoid valve 104 is opened, clean water will flow from the water pipe 91 into the backwash pipe 101 and spray out from multiple second nozzles 102, spraying out high-pressure water flow, which can clear the blockage on the mud removal hole 85.

[0023] Preferably, it also includes a pressure sensor 105, which is disposed on the housing 1. Both the pressure sensor 105 and the solenoid valve 104 are electrically connected to the controller.

[0024] The pressure sensor 105 can detect the pressure of mud and water between the housing 1 and the desliming cylinder 82 (excessive pressure indicates that the desliming hole 85 is blocked). When the data detected by the pressure sensor 105 is greater than the threshold set by the controller, the controller will control the solenoid valve 104 to open, allowing clean water to spray out from the second nozzle 102 to flush the desliming hole 85.

[0025] Preferably, multiple mounting plates 11 are fixed to the side of the housing 1, and each mounting plate 11 is provided with multiple support legs 12.

[0026] The length of the support leg 12 located at the front end of the housing 1 is greater than that of the support leg 12 located at the rear end of the housing 1, so that the housing 1 is in a natural tilted state.

[0027] The working principle of this utility model: The phosphate ore is placed on the feeding rack 2, and under the action of gravity, it falls into the desliming cylinder 82. Opening the electric valve 93 will spray clean water from multiple first nozzles 92 onto the phosphate ore in the desliming cylinder 82 to wash the surface of the phosphate ore. Start the motor 81, and the output torque of the motor 81 is transmitted to the desliming cylinder 82 through the coupling. The rotation of the desliming cylinder 82 will throw the mud and water on the phosphate ore from the desliming hole 85 onto the inner wall of the shell 1. The auger blades 83 will transport the phosphate ore from the rear end of the desliming cylinder 82 to the discharge port 4 at its front end. The mud and water generated after washing will fall onto the inner wall of the shell 1. The flow of the mud and water will be accelerated by the guide plate 5. The mud and water will be introduced into the discharge port 4 through the filter screen 6 and finally discharged from the discharge port 4.
