Description

Technical Field

[0001] This utility model relates to the field of magnesia raw material mixing technology, specifically to a batching and mixing device for magnesia raw materials. Background Technology

[0002] Magnesia, also known as sintered magnesia, is produced by calcining magnesium hydroxide, which is obtained by reacting magnesite, magnesia, or seawater with lime milk at high temperatures. It has a strong hydration ability and is mainly used to make alkaline refractory materials, such as magnesia bricks and magnesia-alumina bricks. Magnesia with more impurities is used to pave the bottom of steelmaking furnaces. In the production process of magnesia, multiple different raw materials need to be put into the mixing tank at the same time and mixed.

[0003] A dust-reducing magnesia raw material mixing device, disclosed in CN222805088U, includes a mixing cylinder. A feed pipe is installed at the top center of the mixing cylinder, and mounting plates are installed on both sides of the top of the feed pipe. Electric push rods are installed on one side of the top of each of the two sets of mounting plates, and scrapers are installed at the bottom of each set of electric push rods. An installation ring is installed on the side surface of the mixing cylinder near the top. The device, with its mounting plates, electric push rods, scrapers, installation rings, through holes, dust collection cylinder, connecting pipe, air pump, collection pipe, filter plate, collection cylinder, and threaded pipe, effectively solves the problem that existing mixing devices, when multiple different raw materials are simultaneously placed inside the mixing cylinder and mixed, easily generate large amounts of dust, affecting the surrounding environment and even causing users to inhale large amounts of dust, thus impacting their physical and mental health.

[0004] However, the patent still has the following problems in actual use: when the device is feeding magnesia raw material, it is not easy to control the feeding speed, which makes it difficult to add and mix the magnesia raw material evenly, and it is easy to cause blockage at the feeding port, thereby reducing the subsequent mixing efficiency.

[0005] Therefore, a batching and mixing device for magnesia raw materials is proposed to solve the problems mentioned above. Utility Model Content

[0017] Preferably, the slide bar is fixedly connected to the second spring, the slide bar is slidably connected to the sliding groove, and the slide bar is in contact with the inner wall of the sliding groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a mixing component and a guiding component, the scraper will move back and forth in a straight line, pushing and flattening the magnesia raw material on the top of the conveyor belt, avoiding excessive accumulation in some areas. The stirring rod drives the slide bar and scraper to rotate, performing uniform mixing. The slide bar drives the scraper to move until the scraper is pressed against the inner wall of the mixing box, facilitating the scraping and cleaning of the magnesia raw material remaining on the inner wall of the mixing box, thus improving the mixing effect. The specific details are as follows:

[0019] By setting up a mixing component, after the magnesia raw material enters the mixing box, the operator starts the stepper motor. The stepper motor drives the rotating shaft to rotate, which in turn drives the stirring rod to rotate. The stirring rod drives the slide bar and scraper to rotate, and the slide bar, subjected to centrifugal force, slides out from the inside of the sliding groove. The slide bar stretches the second spring, and at the same time, the slide bar drives the scraper to move until the scraper is pressed against the inner wall of the mixing box, which facilitates the scraping and cleaning of the magnesia raw material remaining on the inner wall of the mixing box, thus improving the mixing effect.

[0020] By setting up a material guiding component, the drive motor drives the active roller of the conveyor belt to rotate, thereby driving the conveyor belt to transport the magnesia raw material at the top. At the same time, the operator starts the servo motor, which drives the side shaft and auxiliary roller to rotate. The auxiliary roller assists the conveyor belt in its transmission. The side shaft drives the main gear to rotate, the main gear drives the driven gear and vertical shaft to rotate, the vertical shaft drives the push plate to rotate, the push plate drives the push block to rotate, and the push block rotates to squeeze the inclined surface of the inclined block, thereby driving the inclined block to move. The inclined block drives the scraper and slider to move. The slider slides inside the inner groove and compresses the first spring. When the push block rotates to separate from the inclined block, the elastic force of the first spring drives the slider and scraper to slide back to their original position, so that the scraper will move linearly back and forth. The scraper pushes and flattens the magnesia raw material at the top of the conveyor belt, avoiding excessive accumulation in some areas. Then the flattened magnesia raw material enters the mixing box through the feeding plate, which facilitates uniform feeding and facilitates the subsequent mixing and processing.

[0030] Please see Figure 1 - Figure 7 The present invention provides a technical solution: a batching and mixing device for magnesia raw materials, including a mounting frame 1, an auxiliary roller 5, a mixing box 8 and a support leg 2 fixedly connected to the bottom of the mounting frame 1. A conveyor belt 3 is fixedly installed inside the mounting frame 1, and a drive motor 4 is fixedly installed on one side of the back of the mounting frame 1. The output end of the drive motor 4 is fixedly connected to the drive roller of the conveyor belt 3.

[0031] The auxiliary roller 5 is located in the middle of the inside of the conveyor belt 3. The auxiliary roller 5 is rotatably connected to the mounting frame 1. The material guide assembly 6 is provided in the middle of the outer side of the mounting frame 1. The bottom of the mixing box 8 is fixedly connected to the support column 10.

[0032] The top of the mixing box 8 is fixedly connected to the guide trough 11, and the bottom of the mixing box 8 is provided with the discharge port 12.

[0033] The material guiding assembly 6 includes a side shaft 61 that is symmetrically rotatably connected to the outside of the mounting frame 1. A servo motor 62 is fixedly installed in the middle of one side of the back of the mounting frame 1. The output end of the servo motor 62 is fixedly connected to the side shaft 61 on the back. Two vertical shafts 65 are symmetrically rotatably installed on the top of the mounting frame 1. A push plate 67 is fixedly connected to the upper outer side of the vertical shaft 65. A push block 68 is fixedly connected to the bottom of the push plate 67. A scraper 612 is slidably installed on the inner wall of the mounting frame 1.

[0034] There are no fewer than four support legs 2. A feeding plate 7 is fixedly connected to the side of the mounting frame 1 near the guide trough 11. The feeding plate 7 overlaps with the guide trough 11. The side shaft 61 is fixedly connected to the auxiliary roller 5.

[0035] A main gear 63 is fixedly connected to the outer side of the side shaft 61, and a driven gear 66 is fixedly connected to the bottom end of the vertical shaft 65. The main gear 63 and the driven gear 66 are meshed together.

[0036] A connecting plate 64 is fixedly connected to the middle of the outer side of the vertical shaft 65. The connecting plate 64 is fixedly connected to the top of the mounting frame 1. The inner wall of the mounting frame 1 is symmetrically provided with an inner groove 69. A slider 610 is fixedly connected to the side of the scraper 612 near the inner groove 69.

[0037] The slider 610 is slidably connected to the inner groove 69. A spring 611 is fixedly connected to one side of the inner groove 69. The slider 610 is fixedly connected to the spring 611. An inclined block 613 is fixedly connected to the top of the scraper 612.

[0038] The drive motor 4 drives the active roller of the conveyor belt 3 to rotate, thereby driving the conveyor belt 3 to transport the magnesia raw material at the top. At the same time, the operator starts the servo motor 62 to work. The servo motor 62 drives the side shaft 61 and the auxiliary roller 5 to rotate. The auxiliary roller 5 assists the transmission of the conveyor belt 3. The side shaft 61 drives the main gear 63 to rotate. The main gear 63 drives the driven gear 66 and the vertical shaft 65 to rotate. The vertical shaft 65 drives the push plate 67 to rotate. The push plate 67 drives the push block 68 to rotate. The push block 68 rotates and squeezes the inclined surface of the inclined block 613, thereby driving the inclined block 613 to move. The inclined block 613 drives the scraper plate 612 and the slider 610 to move. The slider 610 slides inside the inner groove 69 and compresses the spring 611.

[0039] When the pusher block 68 rotates to separate from the inclined block 613, the elastic force of the spring 611 drives the slider 610 and the scraper 612 to slide and reset, causing the scraper 612 to move back and forth in a straight line. The scraper 612 pushes and flattens the magnesia raw material on the top of the conveyor belt 3, avoiding excessive accumulation in some areas. Then, the flattened magnesia raw material enters the mixing box 8 through the feeding plate 7, which facilitates uniform feeding and facilitates the subsequent mixing and processing.

[0040] The mixing chamber 8 is equipped with a mixing component 9. The mixing component 9 includes a stepper motor 91 fixedly installed at the bottom of the mixing chamber 8. The output end of the stepper motor 91 passes through the mixing chamber 8 and is fixedly connected to a rotating shaft 92. A stirring rod 93 is fixedly connected to the outside of the rotating shaft 92. A slide bar 96 is slidably installed on the side of the stirring rod 93 away from the rotating shaft 92. A scraper 97 is fixedly connected to the side of the slide bar 96 away from the stirring rod 93.

[0041] The stirring rods 93 are symmetrically arranged, and there are no fewer than four stirring rods 93. A sliding groove 94 is provided on the side of the stirring rod 93 near the slide bar 96, and a spring 95 is fixedly connected to one side of the inner wall of the sliding groove 94.

[0042] After the magnesia raw material enters the mixing box 8, the operator starts the stepper motor 91. The stepper motor 91 drives the rotating shaft 92 to rotate, the rotating shaft 92 drives the stirring rod 93 to rotate, and the stirring rod 93 drives the slide bar 96 and the scraper 97 to rotate. The slide bar 96 is subjected to centrifugal force and slides out from the inside of the sliding groove 94. The slide bar 96 stretches the spring 95. At the same time, the slide bar 96 drives the scraper 97 to move until the scraper 97 is pressed against the inner wall of the mixing box 8, which facilitates the scraping and cleaning of the magnesia raw material remaining on the inner wall of the mixing box 8 and improves the mixing effect. The discharge port 12 is equipped with a discharge pipe inside and a shut-off valve is installed on the outside of the discharge pipe to facilitate the discharge of the mixed magnesia raw material.

[0043] The slider 96 is fixedly connected to the spring 95, and the slider 96 is slidably connected to the sliding groove 94, with the slider 96 fitting against the inner wall of the sliding groove 94.

[0044] Working principle:

[0045] Before using this batching and mixing equipment for magnesia raw materials, it is necessary to check the overall condition of the equipment to ensure that it can operate normally. Figure 1 - Figure 7As shown, the operator starts the servo motor 62, which drives the side shaft 61 and auxiliary roller 5 to rotate. The auxiliary roller 5 assists in the transmission of the conveyor belt 3. The side shaft 61 drives the main gear 63 to rotate, which in turn drives the driven gear 66 and vertical shaft 65 to rotate. The vertical shaft 65 drives the push plate 67 to rotate, which in turn drives the push block 68 to rotate. The push block 68 rotates and presses against the inclined surface of the inclined block 613. The inclined block 613 drives the scraper plate 612 and the slider 610 to move. When the push block 68 rotates to the point where it separates from the inclined block 613, the elastic force of the spring 611 causes the slider 610 and the scraper plate 612 to slide back to their original positions. This causes the scraper plate 612 to move linearly back and forth, pushing and flattening the magnesia raw material on the top of the conveyor belt 3, preventing excessive accumulation in certain areas. Next, the spread-out magnesia raw material enters the mixing box 8 through the feeding plate 7 for uniform feeding. After the magnesia raw material enters the mixing box 8, the operator starts the stepper motor 91. The stepper motor 91 drives the rotating shaft 92 to rotate, which in turn drives the stirring rod 93 to rotate. The stirring rod 93 drives the slide bar 96 and the scraper plate 97 to rotate. The slide bar 96 is subjected to centrifugal force and slides outward from the inside of the sliding groove 94. The slide bar 96 stretches the spring 95, and at the same time, the slide bar 96 drives the scraper plate 97 to move until the scraper plate 97 is pressed against the inner wall of the mixing box 8, which facilitates the scraping and cleaning of the magnesia raw material remaining on the inner wall of the mixing box 8 and improves the mixing effect. A discharge pipe is installed inside the discharge port 12, and a shut-off valve is installed on the outside of the discharge pipe to facilitate the discharge of the mixed magnesia raw material.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
