Description

Technical Field

[0001] This utility model relates to the field of ore screening technology, and in particular to an integrated ore screening plate. Background Technology

[0002] Ore screening is the process of classifying loose materials by particle size through sieves. In mineral processing plants, it is often combined with crushing operations to improve beneficiation efficiency and product quality. The main functions of screening include pre-screening, which separates qualified particles that meet the particle size requirements before the ore enters the crusher, thereby preventing over-crushing and improving crushing efficiency. Furthermore, screening equipment plays a crucial role in mineral beneficiation; by optimizing screening technology and processes, ore quality and overall processing capacity can be effectively improved.

[0003] In the ore screening process, the screening plate, as a core component, directly affects the material residence time and screening accuracy due to its screen surface angle. However, most ore screening plates on the market currently adopt a fixed installation structure, and the screen surface angle cannot be adjusted according to material characteristics or production needs. This results in the material having too short a residence time on the screen surface and passing through the screen too quickly, leading to a decrease in screening accuracy. Fine particles are discharged before being fully screened, affecting the effect of subsequent mineral processing. This fixed design has poor adaptability to ores with different particle size distributions or varying moisture content, limiting the overall performance and applicability of the screening equipment. Therefore, improvement is needed. Utility Model Content

[0004] One objective of this invention is to provide an integrated ore screening plate. This invention addresses the problem mentioned in the background that most commercially available ore screening plates adopt a fixed installation structure, and the screen surface inclination angle cannot be adjusted according to material characteristics or production needs. This results in the material having too short a residence time on the screen surface and passing through the screen too quickly, leading to a decrease in screening accuracy. Fine-grained materials are discharged before being fully screened, affecting the effect of subsequent mineral processing. This fixed design has poor adaptability to ores with different particle size distributions or varying moisture content, limiting the overall performance and applicability of the screening equipment.

[0005] An integrated ore screening plate according to an embodiment of the present utility model includes:

[0006] A screen adjustment mechanism includes a screening plate and a frame at its bottom. The frame is installed on a screening device. A rotating block and a rotating seat are fixedly installed at one end of the screening plate and the frame, respectively. Mounting plates are provided on both sides of the bottom of the screening plate. A guide groove is opened inside the mounting plate. A lifting plate is rotatably installed on the top of the frame corresponding to the position of the mounting plate. A first guide rod is fixedly installed at one end of the top of the lifting plate corresponding to the guide groove. Screws are rotatably installed on both sides inside the frame. A moving block is threadedly installed on the outside of the screws. A second guide rod is fixedly installed on both sides of the moving block. A push-pull rod is rotatably installed between the eccentric part of the outside of the lifting plate and the outside of the second guide rod. The screening plate is connected to the frame through a drive assembly to realize the adjustment of the screen angle. A dust collection mechanism is installed on the top of the screening plate.

[0007] Preferably, the rotating block and the rotating seat are rotatably connected.

[0008] Preferably, the mounting plate is fixed to the screening plate by bolts.

[0009] Preferably, the first guide rod is adapted to the guide groove, and the first guide rod slides laterally horizontally inside the guide groove.

[0010] Preferably, the moving block and the second guide seat both slide in the slots inside the frame, and the second guide rod passes through the interior of the frame.

[0011] Preferably, the drive assembly includes a driven bevel gear fixed to the end of the screw and a rotating rod rotating inside one end of the frame. A driving bevel gear is fixedly provided on the outer side of the rotating rod corresponding to the driven bevel gear, and the driven bevel gear and the driving bevel gear are meshed and driven.

[0012] Preferably, a handle is fixedly provided at the end of the rotating rod.

[0013] Preferably, the dust collection mechanism includes a fixed frame that is bolted to the top of the screening plate, a dust collection disc that is fixedly installed at the bottom of the fixed frame, a suction pump that is connected to the dust collection disc that is fixedly installed at the top of the fixed frame, a delivery pipe that is fixedly installed at the top of the suction pump, and the delivery pipe that is connected to an external collection box.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model, through its screen surface adjustment mechanism, effectively avoids the problems of material passing through the screen too quickly and screening accuracy decreasing due to the non-adjustable screen angle in traditional fixed screening plates. In use, rotating the handle drives the rotating rod to rotate, causing the active bevel gear to mesh and drive the driven bevel gears on both sides, synchronously pushing the screw to rotate. The rotation of the screw forces the moving block to move horizontally along the groove inside the frame. Through the second guide rod and the linkage push-pull rod, the lifting plate is lifted. The first guide rod at the top of the lifting plate slides laterally along the guide groove of the mounting plate, thereby lifting the screening plate and precisely adjusting the tilt angle with the rotating block and rotating seat as fulcrum. Therefore, this mechanism improves the adaptability of the screening equipment to ores with different particle size distributions and humidity changes, ensures the full screening of fine-grained materials, and optimizes screening efficiency and product quality.

[0016] 2. This utility model effectively avoids the problems of deteriorated working environment, accelerated equipment wear and health hazards caused by dust flying during ore screening by setting up a dust suction mechanism. During the screening process, the suction pump creates negative pressure in the dust suction disc, and the dust raised on the surface of the screening plate is sucked into the dust suction disc in real time. The dust is directly transported to the external collection box for centralized treatment through the conveying pipe, thereby realizing the cleanliness and safety of the screening operation, and improving the overall quality of the production environment and the long-term operational stability of the equipment.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] refer to Figures 1-6 An integrated ore screening plate, comprising:

[0027] The screen surface adjustment mechanism 1 includes a screening plate 101 and a frame 102 located at its bottom. The frame 102 is installed on the screening equipment. A rotating block 103 and a rotating seat 104 are respectively fixedly installed at one end of the screening plate 101 and the frame 102. Mounting plates 105 are provided on both sides of the bottom of the screening plate 101. A guide groove 106 is opened inside the mounting plate 105. A lifting plate 107 is rotatably installed on the top of the frame 102 corresponding to the position of the mounting plate 105. The top of the lifting plate 107... A first guide rod 108 is fixedly provided at one end of the guide groove 106. Screws 109 are rotatably provided on both sides inside the frame 102. A moving block 110 is threadedly provided on the outside of the screws 109. A second guide rod 111 is fixedly provided on both sides of the moving block 110. A push-pull rod 112 is rotatably provided between the eccentric part of the outer side of the lifting plate 107 and the outer side of the second guide rod 111. The screening plate 101 is connected to the frame 102 through a drive assembly to realize the adjustment of the screen surface angle.

[0028] The drive assembly includes a driven bevel gear 113 fixed to the end of the screw 109, and a rotating rod 114 rotating inside the frame 102. A driving bevel gear 115 is fixedly provided on the outer side of the rotating rod 114 corresponding to the driven bevel gear 113. The driven bevel gear 113 and the driving bevel gear 115 are meshed and driven. A handle 116 is fixedly provided at the end of the rotating rod 114.

[0029] In use, rotating the handle 116 drives the rotating rod 114 to rotate, causing the active bevel gear 115 to mesh and drive the driven bevel gears 113 on both sides, which in turn push the screw 109 to rotate. The rotation of the screw 109 forces the moving block 110 to move horizontally along the slot inside the frame 102. The second guide rod 111, in conjunction with the push-pull rod 112, pushes the lifting plate 107 to rise. The first guide rod 108 at the top of the lifting plate 107 slides laterally along the guide groove 106 of the mounting plate 105, thereby raising the screening plate 101 and precisely adjusting the tilt angle with the rotating block 103 and the rotating seat 104 as fulcrums.

[0030] Example 1: The rotating block 103 and the rotating seat 104 are rotatably connected, allowing the screening plate 101 to be angled relative to the frame 102. The mounting plate 105 is fixed to the screening plate 101 by bolts. The first guide rod 108 is adapted to the guide groove 106, and the first guide rod 108 slides horizontally inside the guide groove 106 to ensure that the screening plate 101 moves smoothly during adjustment. The moving block 110 and the second guide seat slide in the slot inside the frame 102. The second guide rod 111 passes through the inside of the frame 102. The rotation of the screw 109 drives the moving block 110 to move horizontally, thereby causing the lifting plate 107 to deflect and achieving precise adjustment of the screen surface inclination angle.

[0031] Example 2: A dust collection mechanism 2 is installed on the top of the screening plate 101. The dust collection mechanism 2 includes a fixing frame 201 fixed to the top of the screening plate 101 by bolts. A dust collection disc 202 is fixedly installed at the bottom of the fixing frame 201. A suction pump 203 connected to the dust collection disc 202 is fixedly installed on the top of the fixing frame 201. A conveying pipe 204 is fixedly installed on the top of the suction pump 203. The conveying pipe 204 is connected to an external collection box.

[0032] During the screening process, the suction pump 203 creates negative pressure in the dust collection disc 202, and the dust raised on the surface of the screening plate 101 is sucked into the dust collection disc 202 in real time. The dust is then directly transported to the external collection box for centralized treatment via the conveying pipe 204, thereby achieving clean and safe screening operations and improving the overall quality of the production environment and the long-term operational stability of the equipment.

[0033] Working principle: In use, firstly, rotating the handle 116 drives the rotating rod 114 to rotate. The driving bevel gear 115 on the rotating rod 114 meshes with and drives the driven bevel gears 113 on both sides, thereby synchronously pushing the screw 109 to rotate. The rotation of the screw 109 causes the moving block 110 to move horizontally along the groove inside the frame 102. The moving block 110 drives the second guide rod 111 to push the lifting plate 107 to rise in conjunction with the push-pull rod 112. The first guide rod 108 at the top of the lifting plate 107 slides laterally along the guide groove 106 of the mounting plate 105, thereby lifting the screening plate 101 with the rotating block 103 and the rotating seat 104 as fulcrums, realizing precise adjustment of the screen surface inclination angle and effectively avoiding This invention addresses the problems of material passing through the screen too quickly and reduced screening accuracy caused by the non-adjustable angle of traditional screening plates 101. Simultaneously, the dust collection mechanism 2 installed on top of the screening plate 101 fixes the dust collection disc 202 to the screening plate 101 via a fixing frame 201. During screening, the suction pump 203 is activated, creating negative pressure within the dust collection disc 202 to suck up dust rising from the surface of the screening plate 101 in real time. The dust is then transported via a conveying pipe 204 to an external collection box for centralized treatment. This effectively avoids the impact of dust on the working environment, equipment wear, and worker health, achieving cleaner and safer screening operations and improving the overall quality of the production environment and the long-term operational stability of the equipment.
