Description

Technical Field

[0001] This utility model relates to the field of particle size detection technology, specifically a magnesium oxide uniformity detection system. Background Technology

[0002] The uniformity testing of magnesium oxide is to ensure its consistent quality in applications such as ceramics and refractory materials, avoiding the impact of performance differences on the quality of finished products. It also ensures that when used as a catalyst or additive in chemical reactions, it provides a stable reaction interface and active sites, meeting the stringent performance requirements of high-end fields such as electronic materials. At the same time, it facilitates better mixing with other raw materials during the production process, allows for precise control of process parameters, reduces rework and defective products caused by uneven mixing, and improves production efficiency. Current technologies for testing the uniformity of magnesium oxide typically require the use of a particle size analyzer. The particle size analyzer uses the principle of laser diffraction to collect image data of magnesium oxide under light at different angles. By measuring the intensity of diffracted light at different angles, the particle size distribution is obtained, and then the uniformity is determined.

[0003] Existing technologies require operators to manually place samples in batches on the testing platform when multiple tests are needed on a batch of samples, and then operate a particle size analyzer for testing. After each test, the previous batch of samples needs to be manually unloaded before the next batch is placed, and the testing process is repeated multiple times. The manual operation involves many steps and is quite cumbersome. The time-consuming manual feeding and unloading operations affect the overall testing efficiency, and manual feeding can also result in inaccurate measurements, thus affecting the test data. Therefore, a magnesium oxide uniformity testing system is proposed to solve the above-mentioned problems. Utility Model Content

[0016] 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.

[0017] Example 1 Please see Figures 1-5As shown, a magnesium oxide uniformity detection system includes an operating table 1, on which a mounting shaft 2 is rotatably mounted. A turntable 3 is connected to the top of the mounting shaft 2, and four trays 5 are arranged in a circular array on the turntable 3. A sliding shaft 51 is connected to the bottom of each tray 5. A servo motor 4 is mounted at the bottom of the operating table 1, and the servo motor 4 is configured to rotate intermittently, rotating 90 degrees each time. The output end of the servo motor 4 is connected to the mounting shaft 2. A particle size analyzer 6 is mounted on the operating table 1. The particle size analyzer 6 is existing technology, and its specific structure and working principle will not be described in detail here. The particle size analyzer 6 is equipped with a detection... The probe, when the tray 5 moves, passes under the probe and stops below it. The probe detects the uniformity of the sample on the tray 5. A feeding assembly 7 is installed on the operating table 1. The feeding assembly 7 includes a mounting frame 71, a U-shaped frame 72 slidably mounted on the mounting frame 71, a connecting frame 73 fixedly connected to the mounting frame 71, and a hopper 74 fixedly mounted on the connecting frame 73. A connecting rod 75 is connected to the outer wall of the hopper 74, and a distributing cylinder 76 is connected to the end of the connecting rod 75 away from the hopper 74. A hinged flap 77 is hinged to the bottom of the distributing cylinder 76. A column 78 is connected to the bottom surface of the U-shaped frame 72. The bottom end is connected to an arc-shaped plate 79. The convex frame 72 is provided with a first layer plate and a second layer plate. The first layer plate of the convex frame 72 has a first hole 721, and the second layer plate of the convex frame 72 has a second hole 722. The top surface of the first layer plate of the convex frame 72 is in sliding contact with the bottom of the hopper 74. The top of the distributing cylinder 76 is in sliding contact with the bottom surface of the first layer plate of the convex frame 72. The flip cover 77 is in sliding contact with the top surface of the second layer plate of the convex frame 72. The first hole 721 and the second hole 722 are connected to the arc-shaped plate 79. Hole 722 is offset. When the sliding shaft 51 moves, it slides in contact with the arc-shaped plate 79. A spring is installed between the U-shaped frame 72 and the mounting frame 71. When the tray 5 moves, it passes under the second hole 722. When the turntable 3 rotates, when the tray 5 on the left is about to move under the second hole 722, the sliding shaft 51 at the bottom of the tray 5 abuts against the arc-shaped plate 79 and applies a pushing force to the arc-shaped plate 79, causing the arc-shaped plate 79 to move to the left. The arc-shaped plate 79 passes through the column 78. The convex frame 72 moves to the left. After the first hole 721 on the convex frame 72 moves to the left, the first layer plate abuts against the bottom of the hopper 74, preventing the sample in the hopper 74 from falling. After the second hole 722 moves to the left, it moves to the bottom of the flip cover 77. The second layer plate no longer abuts against the flip cover 77, allowing the flip cover 77 to open. When the tray 5 moves to the bottom of the second hole 722, the flip cover 77 opens, and the sample in the dispensing cylinder 76 falls onto the tray 5, completing the feeding. When the tray 5 rotates again... When in motion, the sliding shaft 51 disengages from the arc-shaped plate 79, and the U-shaped frame 72 resets due to the spring force. The arc-shaped plate 79 then resets as well, and the first hole 721 moves back to below the hopper 74. The second plate again presses against the flip cover 77, closing it. The sample in the hopper 74 enters the dispensing cylinder 76 through the first hole 721 for replenishment, filling the dispensing cylinder 76 with sample, ready for the next feeding. This ensures that the tray 5 passes under the second hole 722 each time.The dispensing cylinder 76 can automatically dispense its internal samples onto the tray 5.

[0018] Furthermore, a sliding rod 711 is slidably connected to the mounting frame 71. A connecting rod 710 is hinged to the bottom of the sliding rod 711. The end of the connecting rod 710 away from the sliding rod 711 is hinged to the U-shaped frame 72. A crossbar 712 is connected to the top of the sliding rod 711. A tilting rod 713 is connected to the end of the crossbar 712 away from the sliding rod 711. The tilting rod 713 is located inside the hopper 74. Multiple blades are connected to the tilting rod 713. When the U-shaped frame 72 moves to the left, the sliding rod 711 moves upward through the connecting rod 710. When the U-shaped frame 72 moves to the right, the sliding rod 711 moves downward through the connecting rod 710. When the sliding rod 711 moves up and down, the tilting rod 713 moves up and down synchronously through the crossbar 712. When the tilting rod 713 moves up and down, the multiple blades above it tilt the sample in the hopper 74, making the sample distribution more uniform and promoting the sample to fall.

[0019] In this embodiment, the feeding component 7 is configured so that each time the tray 5 passes under the second hole 722, the dispensing cylinder 76 can automatically dispose of the sample inside the tray 5 onto the tray 5. The tray 5 then transports the sample to the particle size analyzer 6 for testing, thus achieving the effect of automatic feeding. The tilting rod 713 is configured so that when the tilting rod 713 moves up and down, it flips the sample in the hopper 74 through multiple blades above it, making the sample distribution more uniform and promoting the falling of the sample. The dispensing cylinder 76 can dispense a quantitative amount of material each time, making the sample detection quantity more accurate and stable.

[0020] Example 2 Please see Figures 1-7 As shown, a material spreading assembly 8 is provided on the operating table 1. The material spreading assembly 8 includes a base 81, a serrated strip 82 connected to the base 81, a sliding shaft 51 slidingly contacting the serrated strip 82 when moving, an elastic rod 83 connected to the base 81, and an elastic needle 84 connected to the elastic rod 83. When the tray 5 moves, it passes under the elastic needle 84. The tray 5, sliding shaft 51, base 81, serrated strip 82, elastic rod 83, and elastic needle 84 are all made of elastic materials. During the time the tray 5 passes under the elastic needle 84, the sliding shaft 51 contacts the serrated strip 82, causing the serrated strip 82 to vibrate. The sliding shaft 51 itself also drives the tray 5 to vibrate. The tray 5 can disperse the sample on it through vibration. When the serrated strip 82 vibrates, it drives the elastic needle 84 to vibrate through the base 81 and the elastic rod 83. When the elastic needle 84 vibrates, it contacts the sample on the tray 5, flattening the sample and spreading it evenly on the tray 5.

[0021] In addition, the operating table 1 is equipped with a unloading assembly 9, which includes a corner bar 91. The corner bar 91 is installed on the operating table 1, and a brush 92 is installed on the corner bar 91. When the top surface of the tray 5 moves, it contacts the brush 92. The operating table 1 is equipped with a square groove, which is located below the brush 92. A collection box 93 is slidably installed at the bottom of the operating table 1, which is located below the square groove. After the sample on the tray 5 is tested, it passes under the brush 92. During this process, the brush 92 brushes the sample off the tray 5. The sample falls into the collection box 93 through the square groove of the operating table 1. The collection box 93 can be pulled out for easy handling by the operator.

[0022] In this embodiment, the spreading component 8 utilizes the vibration of the tray 5 itself and the agitation of the elastic needle 84 to disperse and spread the sample evenly on the tray 5, facilitating the particle size analyzer 6 for detection and avoiding localized sample accumulation that could affect the detection results. The unloading component 9 allows the brush 92 to brush the sample from the tray 5 into the collection box 93 for collection. Through the cyclical movement of the four trays 5, the processes of feeding, spreading, detection, and unloading can be continuously and automatically completed, improving the level of automation and accelerating the detection efficiency.

[0023] In this utility model, a magnesium oxide uniformity detection system is used where the servo motor 4 is set to rotate intermittently, rotating 90 degrees each time. When the servo motor 4 rotates, it drives the turntable 3 to rotate via the mounting shaft 2. The turntable 3 then drives four trays 5 to rotate, thus allowing the four trays 5 to intermittently revolve 90 degrees. The particle size analyzer 6 is existing technology; its specific structure and working principle will not be detailed here. The particle size analyzer 6 is equipped with a detection probe. When the trays 5 move, they pass under and stop below the detection probe. The detection probe detects the uniformity of the sample on the trays 5. The sample is placed into the hopper 74. When there is no tray 5 below the second hole 722, one... Hole 721 is located below hopper 74. The sample in hopper 74 falls into dispensing cylinder 76 through hole 721. At this time, the flap 77 is closed by the second layer plate of the U-shaped frame 72, and the sample in dispensing cylinder 76 cannot fall temporarily. When the turntable 3 rotates, when the tray 5 on the left is about to move below hole 722, the sliding shaft 51 at the bottom of the tray 5 abuts against the arc plate 79 and applies a pushing force to the arc plate 79, causing the arc plate 79 to move to the left. The arc plate 79 drives the U-shaped frame 72 to move to the left through the column 78. After hole 721 on the U-shaped frame 72 moves to the left, the first layer plate abuts against the bottom of hopper 74, preventing the sample in hopper 74 from falling. After hole 722 moves to the left and is positioned below the flip cover 77, the second-layer plate no longer presses against the flip cover 77, allowing the flip cover 77 to open. When tray 5 moves to below hole 722, the flip cover 77 opens, and the sample in the dispensing cylinder 76 falls onto tray 5, completing the feeding process. When tray 5 rotates again, the sliding shaft 51 disengages from the arc-shaped plate 79, and the U-shaped frame 72 resets due to the spring force. The arc-shaped plate 79 then resets, and hole 721 moves again to below hopper 74. The second-layer plate presses against the flip cover 77 again, closing the flip cover 77. The sample in hopper 74 enters the dispensing cylinder 76 through hole 721 for replenishment, filling the dispensing cylinder 76 with sample, ready for the next sample. The automatic feeding process ensures that each time the tray 5 passes under the second hole 722, the dispensing cylinder 76 automatically places its internal sample onto the tray 5. The tray 5 then transports the sample to the particle size analyzer 6 for testing, achieving the effect of automatic feeding. When the C-shaped frame 72 moves to the left, it drives the sliding rod 711 to move upward via the connecting rod 710. When the C-shaped frame 72 moves to the right, it drives the sliding rod 711 to move downward via the connecting rod 710. When the sliding rod 711 moves up and down, it drives the tilting rod 713 to move up and down synchronously via the crossbar 712. When the tilting rod 713 moves up and down, it flips the sample in the hopper 74 through multiple blades above it, making the sample distribution more uniform and promoting the falling of the sample.

[0024] After tray 5 leaves the area below hole 722, it moves to the area below elastic needle 84. Tray 5, sliding shaft 51, base 81, serrated bar 82, elastic rod 83, and elastic needle 84 are all made of elastic materials. During the time tray 5 passes the elastic needle 84, sliding shaft 51 contacts serrated bar 82, causing serrated bar 82 to vibrate. Sliding shaft 51 itself also drives tray 5 to vibrate. Through vibration, tray 5 can disperse the sample on it. When serrated bar 82 vibrates, it drives elastic needle 84 to vibrate through base 81 and elastic rod 83. When elastic needle 84 vibrates, it contacts the sample on tray 5, flattening the sample and spreading it evenly on tray 5. After tray 5 leaves the area below elastic needle 84, it moves to the area below particle size analyzer 6. Through the vibration of tray 5 itself and the movement of elastic needle 84, the sample is dispersed and spread evenly on tray 5, making it easy for particle size analyzer 6 to detect, and avoiding local accumulation of sample that would affect the detection effect.

[0025] After the sample on tray 5 is tested, it passes under brush 92. During this process, brush 92 brushes the sample off tray 5 and the sample falls into collection box 93 through the square groove of operating table 1. Collection box 93 can be pulled out for easy handling by operators. After tray 5 leaves under brush 92, it moves again to under hole 722. Through the cyclical movement of the four trays 5, the process of feeding, spreading, testing and unloading can be completed automatically, which improves the level of automation and speeds up the testing efficiency.

[0026] The above embodiments are only used to illustrate the present utility model, and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
