Description

Technical Field

[0001] The present invention relates to the technical field of ore washing and screening, and specifically to a compressed air ore washing vibrating screen. Background Art

[0002] Vibrating screens are widely used in the solid particle classification process of various industrial productions. Vibrating screens can generally be divided into circular vibrating screens and rectangular vibrating screens in terms of shape. Circular vibrating screens have a simple structure and are mostly suitable for the classification of small-flow materials. Rectangular vibrating screens can be made into equipment with a larger area and can handle large-flow materials. Ore washing vibrating screens are a kind of screening equipment widely used in the mining industry and other fields, mainly composed of components such as a screen box, vibrating motors, and springs. The screen box is usually made of high-strength steel to ensure firmness and durability. The screen mesh has different mesh numbers and materials according to requirements. Relying on the exciting force generated by the vibrating motors, the materials make high-frequency vibrations on the screen surface. Materials smaller than the screen holes pass through the screen mesh to become undersize materials, and those larger than the screen holes remain on the screen surface and are discharged; The patent application with the publication number CN112090732A discloses a compressed air ore washing vibrating screen, which includes a fixed frame. A conveying device is arranged inside the fixed frame, and a sticky material outlet is arranged at the end of the conveying device; the fixed frame supports an unloading hopper upward, and the conveying device communicates with the unloading hopper upward; the fixed frame is connected with a box body upward, and the box body communicates with the unloading hopper downward; a screen plate is arranged at the bottom of the box body, one end of the box body is connected with a feed inlet and the other end is connected with a target material outlet; an exciter is fixedly connected to the outer wall of the box body; a nozzle fixing plate is arranged inside the box body above the screen plate, a main air pipe is arranged inside the box body above the nozzle fixing plate, and the main air pipe is connected with an air inlet pipe; the nozzle fixing plate is connected with a plurality of nozzles downward, the nozzles are evenly distributed on the nozzle fixing plate, and the air outlet directions of the nozzles are all perpendicular to the screen plate and face the screen plate; The above patent efficiently separates target materials and sticky materials. However, the ore carries sticky materials, and the passing ability of the sticky materials is poor, and even quickly clogs the screen mesh, causing the vibrating screen to completely lose its separation function. It is very difficult to achieve the separation of fine particles of materials containing clay under higher moisture conditions. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the present invention provides a compressed air ore washing vibrating screen to solve the problems raised in the above background art.

[0004] To achieve the above purposes, the present invention is realized through the following technical solutions: A compressed air ore washing vibrating screen, including a fixed seat, and a vibrating mechanism is fixedly connected to the outer wall of the fixed seat; The vibrating mechanism includes: A mounting seat, which is fixedly connected to the outer wall of the fixed seat; A vibrating component, whose outer wall is fixedly connected to the outer wall of the mounting seat; The first spring, which is fixedly connected between the mounting seat and the fixed seat; The rotating plate, a rotating plate is fixedly connected to the top of the mounting seat, and a V-shaped rod is rotatably connected to the top of the rotating plate. The rotatable V-shaped rod and the inclined mounting seat are provided, so that the ore can roll with the shaking of the V-shaped rod during the screening process, reducing the retention and caking of viscous materials at the sieve holes. At the same time, the inclination angle design of the V-shaped rod can guide the material to quickly slide into the second recovery box, significantly reducing the risk of screen blockage.

[0005] Preferably, a first recovery box and a second recovery box are fixedly connected to the outer wall of the fixed seat.

[0006] Preferably, the first recovery box is arranged at the bottom position of the vibration mechanism, and the first recovery box is arranged at the lower position where the V-shaped rod is inclined.

[0007] Preferably, holes are formed in the outer wall of the second recovery box, and a door panel is rotatably connected to the position of the hole on the outer wall of the second recovery box.

[0008] Preferably, an auxiliary mechanism is fixedly connected to the top of the mounting seat. The mounting seat is inclined, and then the V-shaped rod is installed on the mounting seat through the rotating plate. When the ore falls on the V-shaped rod, the vibration component is powered on and started to drive the shaking of the mounting seat, thereby driving the shaking of the V-shaped rod and the rotating plate, and then screening the ore on the V-shaped rod. Moreover, since the V-shaped rod and the rotating plate are rotatably connected, the V-shaped rod can shake. The shaking of the V-shaped rod reduces the ore and sediment from getting stuck between the V-shaped rods. The V-shaped rod is inclined, so it guides the screened ore to fall into the second recovery box. Holes are formed in the corrugated pipe for the ore to fall into the second recovery box.

[0009] Preferably, the auxiliary mechanism includes a corrugated pipe, the corrugated pipe is fixedly connected to the top of the mounting seat, a blocking bin is fixedly connected to the top of the corrugated pipe, a feeding port is formed in the top of the blocking bin, and a first support is fixed between the feeding port and the blocking bin. The compression bin in the auxiliary mechanism periodically releases high-pressure air flow through a fan and a solenoid valve. Combined with the water spraying design of the blocking bin, the dual effects of air flow impact and water washing can be achieved simultaneously. The high-pressure air flow directly flushes the viscous materials on the surface of the ore and in the gaps of the V-shaped rods, and the water washing further softens and separates the clay, effectively solving the problem of separating fine particles in high-moisture materials.

[0010] Preferably, a second bracket is fixedly connected to the top of the feed inlet, the fixing seat fixes the intercepting bin, and the intercepting bin and the mounting seat are connected by a zigzag tube, thereby confining the ore in the intercepting bin and the zigzag tube, thereby effectively screening the ore, and the zigzag tube is made of elastic material, so the zigzag tube will be squeezed and contracted when the mounting seat moves. A feed inlet is provided on the top of the intercepting bin, and the ore to be screened can be put into the intercepting bin and the zigzag tube from the feed inlet, and then the zigzag tube will be squeezed during the vibration of the mounting seat. At this time, a baffle is set in the feed inlet, and the limit plate intercepts the baffle, thereby preventing the airflow from being discharged from the feed inlet. At this time, the zigzag tube is squeezed in The space is reduced, and the air flow will be discharged from the gap of the rotating plate and the lower part of the rotating plate respectively, thereby reducing the adhesion of ore and sticky materials. The outer wall of the second bracket is fixedly connected to the second spring, and the bottom of the second spring is fixedly connected to a baffle, and the baffle is located in the feed inlet. The inner wall of the feed inlet is located at the top of the baffle and is fixedly connected to a limiting plate. The zigzag tube is made of elastic material and produces periodic extrusion and contraction with the vibration of the mounting seat, so that the material in the tube continues to flow in the dynamic space change, reducing the adhesion of sticky materials to the tube wall. At the same time, the matching design of the baffle and the second spring ensures that only ore is allowed to enter during feeding, avoiding material splashing caused by airflow recoil.

[0011] Preferably, the top of the intercepting bin is fixedly connected to a compression bin, the compression bin is communicated with the interior of the intercepting bin, the outer wall of the compression bin is fixedly connected to a solenoid valve, the outer wall of the compression bin is fixedly connected to a fan, the solenoid valve is opened at a timer, the system can automatically complete the compressed air purge, and promptly remove the residual materials on the screen and the V-shaped rod without stopping for manual cleaning, and combined with the double-box design of the first recycling box and the second recycling box, continuous screening and cleaning operations are realized, which significantly improves the operating efficiency and stability of the equipment, and a third bracket is fixedly connected between the fan and the intercepting bin.

[0012] The present invention provides a compressed air ore washing vibrating screen. It has the following beneficial effects: 1. The compressed air ore washing vibrating screen is equipped with a rotatable V-shaped rod and an inclined mounting base, which allows the ore to roll as the V-shaped rod shakes during the screening process, reducing the retention and agglomeration of sticky materials in the screen holes. At the same time, the inclined angle design of the V-shaped rod can guide the material to slide quickly into the second recovery box, significantly reducing the risk of screen clogging.

[0013] 2. The compressed air ore washing vibrating screen periodically releases high-pressure airflow through the compression chamber in the auxiliary mechanism through the fan and solenoid valve. Combined with the water spray design of the interception chamber, it can simultaneously achieve the dual effects of airflow impact and water washing. The high-pressure airflow directly washes the ore surface and the sticky materials in the gap between the V-shaped rods. The water washing further softens and separates the clay, effectively solving the problem of separating fine particles in high-moisture materials.

[0014] 3. The compressed air ore washing vibrating screen is made of elastic material through a zigzag pipe. It generates periodic extrusion and contraction with the vibration of the mounting seat, enabling the material in the pipe to continuously flow in the dynamic space change, reducing the adhesion of viscous materials to the pipe wall. At the same time, the cooperative design of the baffle and the second spring ensures that only ore can enter during feeding, avoiding the material splash caused by the air flow backwash.

[0015] 4. For the compressed air ore washing vibrating screen, through the timed opening of the solenoid valve, the system can automatically complete the compressed air purge, timely remove the residual materials on the screen and the V-shaped rods, without the need for manual cleaning during shutdown. Combining the double-box design of the first recovery box and the second recovery box, it realizes the continuous operation of screening and cleaning, significantly improving the operation efficiency and stability of the equipment.

When the ore falls onto the V-shaped rod 23, the vibrating component 21 is powered on and starts to drive the mounting seat 22 to shake, thereby driving the V-shaped rod 23 and the rotating plate 24 to shake, and then screening the ore on the V-shaped rod 23; A vibrating component 21, the outer wall of the vibrating component 21 is fixedly connected to the outer wall of the mounting seat 22, the V-shaped rod 23 and the rotating plate 24 are rotatably connected, so the V-shaped rod 23 can shake.

The zigzag pipe 61 is provided with holes for the ore to fall into the second recovery box 4; A door panel 5 is provided on the second recovery box 4, and the door panel 5 can be opened to take out the ore after the work is completed. After the work is completed, the first recovery box 3 can also be cleaned.

[0024] Embodiment 2, please refer to Figure 1-8 , on the basis of Embodiment 1, the present invention provides a technical solution: The top of the mounting base 22 is fixedly connected with an auxiliary mechanism 6.

[0025] The auxiliary mechanism 6 includes a zigzag pipe 61. The zigzag pipe 61 is fixedly connected to the top of the mounting base 22. The top of the zigzag pipe 61 is fixedly connected with an interception bin 62. A feeding port 64 is opened at the top of the interception bin 62. A first support 63 is fixed between the feeding port 64 and the interception bin 62. A water pipe is connected to the interception bin 62, and water can be sprayed onto the rotating plate 24 after connecting to a water source.

[0026] The top of the feeding port 64 is fixedly connected with a second support 65. The outer wall of the second support 65 is fixedly connected with a second spring 66. The bottom of the second spring 66 is fixedly connected with a baffle 67. The baffle 67 is located in the feeding port 64. A limiting plate 68 is fixedly connected to the inner wall of the feeding port 64 at the position above the baffle 67; The fixing seat 1 fixes the interception bin 62, and the interception bin 62 is connected to the mounting base 22 through the zigzag pipe 61, thereby restricting the ore in the interception bin 62 and the zigzag pipe 61, and effectively screening the ore. Moreover, the zigzag pipe 61 is made of an elastic material. In this embodiment, it is made of corrosion-resistant ethylene propylene diene monomer rubber. Therefore, when the mounting base 22 moves, it will squeeze and contract the zigzag pipe 61. The feeding port 64 is opened at the top of the interception bin 62, and the ore to be screened can be put into the interception bin 62 and the zigzag pipe 61 from the feeding port 64. Then, during the vibration of the mounting base 22, it will drive the extrusion of the zigzag pipe 61. At this time, the baffle 67 is arranged in the feeding port 64, and the limiting plate 68 intercepts the baffle 67, thereby preventing the air flow from being discharged from the feeding port 64. At this time, the zigzag pipe 61 is squeezed and the space is reduced, and the air flow will be discharged from the gap of the rotating plate 24 and the lower part of the rotating plate 24 respectively, thereby reducing the adhesion of the ore and the viscous material; When the ore is put into the feeding port 64, the baffle 67 will be squeezed down due to the weight of the ore itself, and then the ore will enter the zigzag pipe 61. Then the second spring 66 will drive the baffle 67 to reset.

[0027] A compression chamber 8 is fixedly connected to the top of the interception chamber 62. The compression chamber 8 is internally connected to the interception chamber 62. An electromagnetic valve 7 is fixedly connected to the outer wall of the compression chamber 8. A blower 10 is fixedly connected to the outer wall of the compression chamber 8. A third bracket 9 is fixedly connected between the blower 10 and the interception chamber 62. A water pipe is connected to the interception chamber 62. After connecting to a water source, water can be sprayed onto the rotating plate 24. When the blower 10 is powered on and started, it will blow air into the compression chamber 8. The air continuously enters the compression chamber 8. With the increase of air in the fixed space of the compression chamber 8, the distance between gas molecules is reduced. Then the electromagnetic valve 7 is opened to spray the gas in the compression chamber 8 into the interception chamber 62 and the zigzag pipe 61. Thus, the impact of the air flow guides the sticky materials on the ore to fall off, and the impact of the air flow also drives the V-shaped rod 23 to swing, causing the sticky materials on the V-shaped rod 23 to fall off. The electromagnetic valve 7 will be opened once every three minutes and then closed.
