Description

Technical Field

[0001] This utility model relates to the technical field of calcium powder production equipment, specifically to a vibrating washing screen for ore raw materials used in calcium powder production. Background Technology

[0002] In modern industrial production, calcium carbonate powder is an important basic raw material widely used in many fields such as construction, plastics, rubber, coatings, and papermaking. Its quality directly affects the performance and quality of downstream products. In the calcium carbonate powder production process, the pretreatment of ore raw materials is a crucial step that plays a decisive role in the quality of the final calcium carbonate powder product.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN216026570U) discloses a waterproof display and control instrument, including a first rotating wheel movably mounted on the outer wall of the connecting frame, with a connecting chain connected to the outer side of the first rotating wheel, and a second rotating wheel movably mounted on the right side of the first rotating wheel. This vibrating calcium powder production raw stone cleaning equipment utilizes the vibration of the filter plate frame to move the raw stone, thereby cleaning the raw stone from various angles, and can recycle and reuse the rinsing water, reducing water waste.

[0004] While the aforementioned patent employs eccentric wheels and connecting springs, utilizing the rotation of a second rotating wheel to drive the connecting chain and the first rotating wheels on both sides, with the first rotating wheels connected to the eccentric wheels, allowing multiple eccentric wheels to move simultaneously, and using the simultaneous movement of multiple eccentric wheels to drive the lifting plate and connecting spring within the connecting frame, the lifting plate drives the filter plate frame to move, thereby moving the raw stones placed on the filter plate frame, thus improving cleaning efficiency, its single-layer screening structure cannot meet the needs of calcium powder production for fine grading of ore raw materials with different particle sizes. This results in a large amount of ore needing to be repeatedly screened, increasing energy consumption and production cycle. Furthermore, the fixed angle of the screen surface makes it difficult to adapt to ores with different characteristics. For example, when processing ores with poor flowability, problems such as screen blockage and low screening efficiency are prone to occur.

[0005] Therefore, this utility model provides a vibrating washing screen for ore raw materials in calcium powder production to solve the above problems. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-6 As shown, the purpose of this embodiment is to provide a vibrating washing screen for ore raw materials in calcium powder production, including a processing box 1. A mounting groove 101 is provided on one side of the processing box 1. Multiple limiting grooves 102 are symmetrically provided on the inner side of the processing box 1, and a screening component is provided between the inner sides of the multiple limiting grooves 102. A mounting frame 3 is fixedly connected to the top of the processing box 1. A washing component is fixedly connected to the top of the mounting frame 3. A movable groove 301 is provided on the upper surface of the mounting frame 3, and an adjustment component is provided on the inner side of the movable groove 301. The screening assembly includes sliders 201 that are slidably connected to the inner sides of multiple limiting grooves 102, and a screen frame 202 is rotatably connected between one side of every two sliders 201. The screen aperture of the multiple screen frames 202 gradually decreases from top to bottom. A discharge plate 203 is fixedly connected to one end opening of each of the multiple screen frames 202, and the outlet directions of the multiple discharge plates 203 are different. Two connecting ends 204 are symmetrically fixedly connected to one side of each of the multiple screen frames 202.

[0020] A drive assembly is provided on the inner side of the mounting slot 101. The drive assembly includes a limit frame 6 that is fixedly connected to both the inner and outer sides of the processing box 1. A connecting frame 601 is slidably connected between the inner walls of the limit frame 6. One end of the connecting frame 601 is slidably connected to the inner side of the slide 506. A radial groove 602 is provided on one side of the connecting frame 601.

[0021] The drive assembly also includes a mounting bracket 7 fixedly connected to the inner side of the mounting groove 101. A drive motor B701 is fixedly connected to the inner side of the mounting bracket 7. A rotating wheel 702 is fixedly connected to one end of the output shaft of the drive motor B701. A protrusion 703 is fixedly connected to the side of the rotating wheel 702 that is off-center from the axis, and the outer side of the protrusion 703 is adapted to the inner side of the radial groove 602.

[0022] A support frame 10 is fixedly connected to the outside of the processing box 1, and a shock-absorbing pad 11 is fixedly connected to the bottom of the support frame 10.

[0023] In this embodiment, the screen frame 202 is slidably connected to the inner limiting groove 102 of the processing box 1 via the slider 201, thereby providing a stable support foundation for the screen frame 202 and allowing the screen frame to have a certain amount of room to move.

[0024] Furthermore, the aperture of the multi-layer screen frame 202 gradually decreases from top to bottom in the vertical direction. Under the weight of the raw material and the external force applied by the adjustment component, the grading screen is activated.

[0025] After the ore raw material enters the equipment through the feed hopper 8, it first falls into the uppermost screen frame 202. Then, by starting the drive motor B701, the output shaft drives the rotating wheel 702 to rotate. Since the protrusion 703 is fixedly connected at a position off the axis of the rotating wheel 702, when the rotating wheel 702 rotates, the protrusion 703 slides in the radial groove 602, thereby pushing the connecting frame 601 to slide back and forth along the inner wall of the limiting frame 6. One end of the connecting frame 601 slides with the slide groove 506. In conjunction with this, the fixed seat 505, connecting seat 504, and other components move, which in turn pushes the connecting end 204 via the connecting rod 507, causing the screen frame 202 to vibrate along the direction of the limiting groove 102. Under the vibration of the screen frame 202, the ore is screened according to its particle size. When the raw material particle size is larger than the screen hole of the current screen frame 202, it will be trapped on the screen surface of the current screen frame 202 and continue to participate in the screening process or be discharged through the discharge plate 203; while the raw material with a particle size smaller than the screen hole will fall smoothly into the lower screen frame 202 for finer particle screening. Finally, the ore raw materials of different particle sizes are discharged through the discharge plate 203 of the corresponding screen frame 202, achieving precise grading and providing raw materials of different specifications for subsequent calcium powder production.

[0026] In this embodiment, as Figure 2 and Figure 5As shown, the adjustment assembly includes a support plate 501. The outer side of the support plate 501 is slidably connected to the inner side of the movable groove 301. A drive motor A502 is fixedly connected to the upper surface of the support plate 501. One end of the output shaft of the drive motor A502 passes through the inner wall of the support plate 501 and is fixedly connected to a lead screw 503. A connecting seat 504 is threaded to the outer wall of the lead screw 503. A fixed seat 505 is fixedly connected to one side of the connecting seat 504. A sliding groove 506 is opened on one side of the fixed seat 505. Multiple connecting rods 507 are fixedly connected to both sides of the connecting seat 504, and one end of each of the multiple connecting rods 507 is fixedly connected to the inner wall of multiple connecting ends 204.

[0027] In this embodiment, based on the characteristics of different ore raw materials, the drive motor A502 is started, and its output shaft drives the lead screw 503 to rotate. During rotation, the lead screw 503, through its threaded engagement with the lead screw 503 connecting seat 504, causes the connecting seat 504 to move linearly up and down along the axis of the lead screw 503. The connecting seat 504 is fixedly connected to the connecting end 204 of the screen frame 202 via the connecting rod 507. Therefore, when the connecting seat 504 moves, multiple screen frames 202 rotate around the connection point between the slider 201 and the limiting groove 102, thereby adjusting the tilt angle of the screen frames 202. This adjustment of the screen frame angle allows for flexible modification according to the characteristics of the ore raw materials. For example, with raw materials of poor flowability, the tilt angle of the screen frame 202 can be increased to accelerate the flow rate of the raw materials, prevent screen blockage, and improve the screening throughput.

[0028] In this embodiment, as Figure 4 As shown, the flushing assembly includes a mounting base 401 and a water storage tank 402 fixedly connected to the upper surface of the mounting frame 3. A water inlet valve 403 is fixedly connected to the upper surface of the water storage tank 402. A water pump 404 is fixedly connected to the inner side of the mounting base 401. A connecting pipe A405 is fixedly connected to the input end of the water pump 404. One end of the connecting pipe A405 communicates with the interior of the water storage tank 402. Both output ends of the water pump 404 are fixedly connected to connecting pipes B406. One end of each connecting pipe B406 is fixedly connected to a diversion pipe 407. Multiple drain pipes 408 are fixedly connected to the outer side of the diversion pipe 407. Fixing members 409 are fixedly connected to the outer side of both ends of the diversion pipe 407. One end of each fixing member 409 is fixedly connected to the outer side of the mounting frame 3.

[0029] The top of the mounting frame 3 is fixedly connected to the feed hopper 8, and the bottom of the processing box 1 is fixedly connected to the drain valve 9.

[0030] In this embodiment, by starting the water pump 404, clean water is drawn from the water storage tank 402 through the connecting pipe A405. After being pressurized by the water pump 404, the water is transported to the diversion pipe 407 through the connecting pipe B406. Then, the water is evenly distributed to multiple drain pipes 408 through the diversion pipe 407, and then discharged from the ports of the multiple drain pipes 408. The water sprayed from the drain pipes 408 can cover the ore raw material on the screen frame 202, thereby washing away the mud, dust and other impurities attached to the surface of the ore, thus ensuring the purity of the raw material. The washed wastewater will collect at the bottom of the treatment tank 1 under the action of gravity, and then be discharged through the drain valve 9.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
