Description

Technical Field

[0001] This utility model relates to the field of material screening technology, and more specifically, to a self-cleaning vibration anti-clogging device for a mesh screen. Background Technology

[0002] In the production processes of industries such as mining, metallurgy, and building materials, grate mesh (grid structure) is a core component of screening and feeding equipment. Its function is to separate materials of different particle sizes to ensure that the particle size of materials produced in subsequent processes meets the requirements. However, when processing sticky materials such as wet coal and clay, the material easily adheres to the mesh openings of the grate mesh, causing blockage and leading to the following problems:

[0003] Screening efficiency drops significantly: When the mesh becomes clogged, materials of the correct particle size cannot pass through normally, and screening efficiency can drop by more than 50%, seriously affecting production progress.

[0004] The cleaning methods have defects: traditional manual cleaning requires machine shutdown, which not only interrupts continuous production but also poses a safety risk of operators coming into contact with operating equipment; mechanical scraper cleaning solutions have complex structures, and the scraper is prone to friction with the grate mesh, causing damage to the mesh; high-pressure water washing solutions consume a lot of energy and change the moisture content of the material, making them unsuitable for materials that are sensitive to water.

[0005] Lack of real-time monitoring methods: Existing equipment cannot accurately monitor the degree and location of material blockage, resulting in either delayed cleaning operations (discovering the blockage only after it becomes severe) or excessive cleaning (cleaning even when there is no blockage), wasting energy.

[0006] Sampling requires machine shutdown: Material composition detection requires sampling, but traditional sampling methods require machine shutdown, further reducing the efficiency of continuous equipment operation.

[0007] To address the aforementioned issues, there is currently no solution that simultaneously achieves "real-time monitoring, automatic unblocking, non-stop sampling, and low energy consumption." Therefore, there is an urgent need to design a new type of anti-clogging device for grate mesh. Utility Model Content

[0008] In view of the problems existing in the prior art, the purpose of this utility model is to provide a self-cleaning vibration anti-clogging device for a mesh screen, so as to achieve precise unclogging and sampling without stopping the machine, thereby improving the stability of equipment operation and production continuity.

[0009] The present invention adopts the following technical solution:

[0010] The self-cleaning vibration anti-clogging device for the grate mesh includes multiple vibrators and an infrared imaging detection system. Vibrators are installed at the four corners and the middle of the grate mesh. The infrared imaging detection system is arranged diagonally above the grate mesh and is connected to a controller, which in turn is connected to the vibrators.

[0011] Furthermore, the infrared imaging detection system uses an infrared sensor.

[0012] Furthermore, the mesh includes a frame and a mesh body. The mesh body is installed inside the frame and includes multiple horizontal and vertical mesh rods. The horizontal and vertical mesh rods intersect perpendicularly. Both ends of the horizontal and vertical mesh rods are installed at the frame. A vibrator is installed at each of the four corners of the frame, and a vibrator is installed at the intersection of the middle horizontal and vertical mesh rods.

[0013] Furthermore, multiple sampling bottles are installed on the grate mesh.

[0014] Furthermore, multiple sampling bottle mounting racks are installed on the grate mesh, and sampling bottle mounting rods are provided on both sides of the sampling bottle, with the sampling bottle mounting rods installed at the sampling bottle mounting racks.

[0015] Furthermore, the sampling bottle mounting rack includes a channel steel, which is installed at the mesh body, and a bracket is installed at the channel steel, with the sampling bottle mounting rod placed at the bracket.

[0016] Beneficial effects

[0017] This invention uses an infrared sensor to monitor the light transmittance of the mesh. When the light transmittance drops by 20%, the vibrator is triggered to work.

[0018] This invention achieves precise vibration anti-clogging: the vibrator is synchronously controlled via Bluetooth Mesh networking, and the vibration frequency and duration can be adjusted according to the degree of material blockage;

[0019] This invention incorporates a sampling bottle mounting bracket in the mesh grid, enabling sampling and testing without shutting down the machine. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] This utility model discloses a self-cleaning vibration anti-clogging device for a grate mesh, including multiple vibrators 1 and an infrared imaging detection system. Vibrators 1 are installed at the four corners and the middle of the grate mesh 2. The infrared imaging detection system is arranged diagonally above the grate mesh 2. The infrared imaging detection system is connected to a controller, and the controller is connected to the vibrators 1.

[0027] This utility model is mainly used in screening or feeding equipment equipped with grate mesh in industries such as mining, metallurgy, and building materials. It is especially suitable for processing sticky materials such as wet coal and clay that are easy to clog the mesh.

[0028] The number and distribution of vibrators 1 ensure that the vibration energy can evenly cover the entire grate mesh, avoiding blind spots in local clearing; the vibrators are connected to each other via Bluetooth Mesh networking, which can achieve synchronous or zoned control.

[0029] In one embodiment of this utility model, the infrared imaging detection system is an infrared sensor 3.

[0030] The infrared imaging detection system consists of at least one infrared sensor (preferably an infrared linear array sensor), which is arranged 30-50cm above the grate mesh. If the grate mesh area is large, multiple infrared sensors can be networked together (the detection range of adjacent infrared sensors overlaps by 10%-15%) to ensure no blind spots in monitoring. The infrared sensor 3 is used to collect the transmittance data of the mesh openings and is not affected by the color of the material or dust.

[0031] Infrared imaging system monitors mesh transmittance and establishes a baseline transmittance curve;

[0032] When a local light transmittance decreases by more than a set threshold (e.g., 20%), it is determined to be a blockage.

[0033] The controller activates the vibrator in the corresponding area, which dislodges the blockage material through vibration.

[0034] After the vibration ended, the infrared imaging system checked the transmittance again to confirm the blockage removal effect.

[0035] In one embodiment of this utility model, the mesh 2 includes a frame 21 and a mesh body 22. The mesh body 22 is installed inside the frame 21. The mesh body 22 includes multiple horizontal mesh rods 221 and vertical mesh rods 222. The horizontal mesh rods 221 and vertical mesh rods 222 intersect perpendicularly. Both ends of the horizontal mesh rods 221 and both ends of the vertical mesh rods 222 are installed at the frame. A vibrator 1 is installed at each of the four corners of the frame 21, and a vibrator 1 is installed at the intersection of the middle horizontal mesh rod 221 and the middle vertical mesh rod 222. Here, the number of vibrators 1 is 5.

[0036] In one embodiment of this utility model, a plurality of sampling bottles 4 are installed on the mesh 2. The sampling bottles 4 are used for sampling.

[0037] In one embodiment of this utility model, a plurality of sampling bottle mounting racks 5 are installed on the grate mesh 2, and sampling bottle mounting rods 6 are provided on both sides of the sampling bottle 4. The sampling bottle mounting rods 6 are installed at the sampling bottle mounting racks 5. The bottom of the sampling bottle 4 does not contact the grate mesh 2 to prevent blockage.

[0038] In one embodiment of this utility model, the sampling bottle mounting frame 5 includes a channel steel 51, which is installed at the mesh body 22. A bracket 52 is installed at the channel steel 51, and the sampling bottle mounting rod 6 is placed at the bracket 52. The sampling bottle mounting rod 6 and the bracket 52 are connected in a plug-in manner, which facilitates the removal of the assembly of the sampling bottle mounting rod 6 and the sampling bottle 4. After sampling, the sampling bottle 4 can be directly removed without stopping the machine.

[0039] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
