Description

Technical Field

[0001] This utility model relates to the field of ore crushing equipment cleaning technology, specifically a cleaning device for vibrating screens. Background Technology

[0002] In mineral processing and screening, linear vibrating screens are widely used as important screening equipment for grading and screening materials such as ores, sand, and coal. However, during long-term use, a large amount of material particles, dust, and impurities easily accumulate on the surface and in the gaps of the screen mesh inside the screen box. If these residual materials are not cleaned in time, they will cause a series of problems. For example, the accumulation of residual materials on the screen surface will clog the screen holes, resulting in a significant decrease in the efficiency of subsequent screening operations, affecting the grading accuracy and output of materials. In addition, some corrosive or sticky residual materials will adhere to the screen mesh and the inner wall of the screen box for a long time, which will accelerate the wear and aging of the equipment, shorten the service life of the vibrating screen, and increase the maintenance cost and replacement frequency of the equipment.

[0003] Traditional cleaning methods mostly rely on manual rinsing or simple fixed water spray devices. Manual cleaning is not only labor-intensive and inefficient, but also difficult to thoroughly clean dead corners such as screen gaps. Fixed water spray devices have problems such as limited cleaning range, fixed water outlet angle, and insufficient cleaning pressure, which cannot meet the cleaning needs of residual materials under different screening conditions, resulting in unsatisfactory cleaning effects. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning device for vibrating screens, which solves the problems of limited cleaning range, fixed water outlet angle, and insufficient cleaning pressure in traditional cleaning methods mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for a vibrating screen, comprising a base plate, a linear vibrating screen mounted on the base plate, and a cleaning mechanism mounted on the base plate and used in conjunction with the linear vibrating screen. The cleaning mechanism includes a lifting frame mounted on the base plate, a horizontal moving component mounted on the lifting frame, and a rotating cleaning component mounted on the horizontal moving component. The rotating cleaning component is adapted to the screen box of the linear vibrating screen and is located above the screen box of the linear vibrating screen.

[0006] Furthermore, the lifting frame includes fixed cylinders at the four top corners of the base plate, telescopic rods that slide vertically inside the fixed cylinders, rectangular frames on the four telescopic rods, and cylinders on the base plate; the output shaft of the cylinders is connected to the rectangular frames.

[0007] Furthermore, the horizontal moving assembly includes a first motor disposed on one side of the rectangular frame, a screw rod rotatably disposed between the two longitudinal arms of the rectangular frame, and a moving plate slidably disposed between the two transverse arms of the rectangular frame; the output shaft of the first motor is connected to the screw rod, and the screw rod is threadedly engaged with the moving plate.

[0008] Furthermore, the rotating cleaning assembly includes vertical plates on both sides of the bottom of the moving plate, a water inlet pipe rotatably connected between the two vertical plates, and a driving component on the moving plate; the water inlet pipe is provided with multiple water outlet pipes equidistantly along its length, and valves are provided at both ends of the water inlet pipe; the driving component is connected to the water inlet pipe to drive the water inlet pipe to rotate.

[0009] Furthermore, the driving component includes a second motor mounted on a movable plate, a first pulley connected to the output shaft of the second motor, and a second pulley mounted on the water inlet pipe. The first pulley and the second pulley are connected by a belt drive.

[0010] Furthermore, both ends of the water outlet pipe are located outside the water inlet pipe, with one end of the water outlet pipe sealed and the other end tapered.

[0011] This utility model, through optimized structural design, specifically addresses the shortcomings of existing vibrating screen cleaning technologies, and has the following beneficial effects:

[0012] 1. In the rotating cleaning assembly of this utility model, the water inlet pipe can rotate around its own axis under the drive of the driving component. Combined with the tapered constriction design of the water outlet pipe, the water flow can cover the multi-angle area inside the screen box during the rotation process. At the same time, the horizontal moving component drives the rotating cleaning assembly to move horizontally along the length of the screen box. Combined with the height adjustment function of the lifting frame, the screen and inner wall inside the vibrating screen box are cleaned, effectively removing residual materials.

[0013] 2. The tapered constriction design of the water outlet pipe of this utility model increases the water pressure and enhances the impact force of the water flow on residual materials, which can quickly peel off stubbornly attached materials; the cleaning method that combines rotating cleaning and horizontal movement reduces cleaning time. Compared with traditional manual cleaning or fixed water spray devices, the cleaning efficiency is significantly improved and the cleaning is more thorough.

[0014] 3. This utility model achieves automated adjustment through power components such as cylinders, first motors, and second motors. Workers only need to control the start and stop of each component through the control cabinet to complete the cleaning operation, reducing labor intensity. The lifting frame can flexibly adjust the cleaning height, and the horizontal moving component can adjust the cleaning lateral position, which is suitable for different specifications of vibrating screens or different residue levels, and has strong versatility.

[0015] 4. Regularly cleaning the vibrating screen with this device can prevent residual materials from corroding and wearing the screen mesh and screen box, reduce the equipment failure rate, extend the service life of the vibrating screen, and reduce equipment maintenance and replacement costs.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe them in conjunction with specific embodiments and appendices. Figure 1-2 The present invention will be further described in detail below.

[0021] This utility model discloses a cleaning device for vibrating screens, aiming to solve the problem of inefficient cleaning of residual materials inside the screen box after use. Its overall structure includes a base plate 1, a linear vibrating screen 2, and a cleaning mechanism. The base plate 1 serves as the mounting foundation for the entire device, providing stable support for other components. The linear vibrating screen 2, fixedly mounted on the base plate 1, is the core equipment to be cleaned, and its screen box easily retains residual materials. The cleaning mechanism is also located on the base plate 1 and works in conjunction with the linear vibrating screen 2 to clean the screen mesh inside the screen box of the linear vibrating screen 2. It includes a lifting frame, a horizontal moving component, and a rotating cleaning component, with the rotating cleaning component adapted to and located above the screen box of the linear vibrating screen 2. The specific structural relationships are as follows:

[0022] The lifting frame is used to adjust the overall height of the cleaning mechanism to adapt to different cleaning needs or to raise the cleaning mechanism when not in operation. Its specific structure includes four fixed cylinders 3, four telescopic rods 4, a rectangular frame 5, and a cylinder 6. The four fixed cylinders 3 are vertically fixed at the four top corners of the base plate 1, providing sliding guides for the telescopic rods 4. The four telescopic rods 4 slide vertically through their respective fixed cylinders 3, and can move up and down along the axial direction of the fixed cylinder 3. The rectangular frame 5 is horizontally positioned, with its bottom fixedly connected to the top of the four telescopic rods 4, achieving stable installation through the support of the telescopic rods 4. The cylinder 6 is fixedly mounted on the base plate 1, with its output shaft vertically upward and fixedly connected to the bottom center of the rectangular frame 5. The extension and retraction of the cylinder 6's output shaft drives the rectangular frame 5 and the telescopic rods 4 to move up and down along the fixed cylinders 3, thereby achieving height adjustment of the lifting frame.

[0023] The horizontal moving assembly is used to drive the rotating cleaning assembly to move horizontally, thereby expanding the cleaning range. Its specific structure includes a first motor 7, a screw 8, and a moving plate 9. The first motor 7 is fixedly mounted on one longitudinal arm of the rectangular frame 5, serving as the power source for horizontal movement. The screw 8 is horizontally rotatable between the two longitudinal arms of the rectangular frame 5, with one end fixedly connected to the output shaft of the first motor 7 via a coupling, allowing it to rotate around its own axis under the drive of the first motor 7. The moving plate 9 is horizontally slidable between the two transverse arms of the rectangular frame 5, threadedly engaged with the screw 8. When the screw 8 rotates, the moving plate 9 slides horizontally along the transverse arm direction of the rectangular frame 5 under the action of the threaded driving force.

[0024] The rotating cleaning assembly is the core component that directly achieves the cleaning function, cleaning the screen box through a combination of rotation and water spraying. Its specific structure includes two vertical plates 10, an inlet pipe 11, multiple outlet pipes 12, a valve 13, and a drive unit. There are two vertical plates 10, vertically fixed on both sides of the bottom of the movable plate 9, used to support the inlet pipe 11. The inlet pipe 11 is a stainless steel pipe, horizontally rotatably connected between the two vertical plates 10, with its two ends respectively connected to the corresponding vertical plate 10 via bearings, allowing it to rotate freely around its own axis. The inlet pipe 11 is used to supply cleaning water. Multiple outlet pipes 12 are equidistantly arranged along the length of the inlet pipe 11, each outlet pipe 12 communicating internally with the inlet pipe 11. Both ends of the outlet pipe 12 are located outside the inlet pipe 11, with one end sealed and the other end tapered; the tapered design increases the water pressure and enhances the cleaning effect, while the sealed end prevents unnecessary water loss. Valves 13 are respectively installed at both ends of the inlet pipe 11 to control the flow and volume of water within the inlet pipe 11. A drive unit is mounted on the movable plate 9 and is connected to the inlet pipe 11 for driving its rotation. It includes a second motor 14, a first pulley 15, and a second pulley 16. The second motor 14 is fixedly mounted on the movable plate 9, the first pulley 15 is fixedly connected to the output shaft of the second motor 14, and the second pulley 16 is fixedly sleeved on the middle part of the inlet pipe 11. The first pulley 15 and the second pulley 16 are connected by a belt drive. When the second motor 14 operates, it drives the inlet pipe 11 to rotate through the first pulley 15, the second pulley 16, and the belt.

[0025] The cylinder 6, first motor 7, and second motor 14 of this device all have self-locking functions. The water inlet pipe 11 is connected to the factory's industrial circulating cooling water or other water sources via a soft water pipe and a water pump. All power-consuming equipment, including the cylinder 6, first motor 7, second motor 14, and water pump, is powered through the factory's power supply system and electrical control box, and its start and stop are controlled by the control cabinet. It should be further noted that the linear vibrating screen 2, cylinder 6, first motor 7, screw 8, valve 13, second motor 14, bearings, pulleys, belts, water pipes, and other components involved in this device are all commercially available and readily available products. Specific models and specifications can be selected based on the application scenario. Personnel do not need to understand their specific structure and working principle; as long as the product functions normally, it will not affect the specific implementation of this utility model. Further details are omitted here.

[0026] When the linear vibrating screen 2 needs cleaning after completing the screening process, the working process of this utility model is as follows:

[0027] 1. Height adjustment: Start cylinder 6, the output shaft of cylinder 6 extends and retracts, driving the rectangular frame 5 and the telescopic rod 4 to move up and down along the fixed cylinder 3, adjusting the rotating cleaning component to a suitable height corresponding to the screen box of the linear vibrating screen 2.

[0028] 2. Horizontal position adjustment: Start the first motor 7. The output shaft of the first motor 7 drives the screw 8 to rotate. The moving plate 9, which is threaded with the screw 8, slides horizontally along the cross arm of the rectangular frame 5, moving the rotating cleaning component above the area to be cleaned in the screen box.

[0029] 3. Cleaning operation: Connect the water source to one end of the water inlet pipe 11, open the valve at the end connected to the water source, and close the valve 13 at the other end. The cleaning water enters through the water inlet pipe 11 and sprays out from the constricted ends of each water outlet pipe 12. The second motor 14 can be started, and the second motor 14 drives the water inlet pipe 11 to rotate through the first pulley 15, the belt and the second pulley 16, so that the water outlet pipe 12 rotates together with the water inlet pipe 11. The water flow increases the cleaning range under the action of rotation.

[0030] 4. Coverage: During the cleaning process, the first motor 7 can be controlled to drive the moving plate 9 to move horizontally, so that the rotating cleaning component can move along the length of the screen box, thereby achieving comprehensive cleaning of the entire area of ​​the screen box.

[0031] 5. End of operation: After cleaning is completed, close valve 13 to stop water supply, turn off the second motor 14 and the first motor 7, and raise the cleaning mechanism through cylinder 6 to complete the entire cleaning operation.

[0032] This invention achieves efficient and comprehensive cleaning of the vibrating screen box through the coordinated operation of the lifting frame, horizontal moving component, and rotating cleaning component. It is easy to operate and has a good cleaning effect.
