Description

Technical Field

[0001] This utility model relates to the field of magnesium oxide expanding agent technology, and in particular to a magnesium oxide expanding agent preparation device. Background Technology

[0002] In the field of building materials, magnesium oxide expansive agents, as an important additive, play a crucial role in optimizing the performance of concrete. With increasingly stringent requirements for concrete quality in construction projects, such as the need for precise control of shrinkage and expansion in large-volume concrete structures to prevent cracking and ensure the durability of building structures, [further development is needed].

[0003] Traditional methods of preparing magnesium oxide expanding agents rely heavily on manual operation, which has many drawbacks. Firstly, manual weighing of raw materials is not only inefficient but also makes it difficult to ensure precise proportions, easily leading to unstable product quality due to human error and affecting the final performance of concrete. Secondly, the lack of systematic integration during the storage, transportation, and addition of different raw materials easily causes material spillage and pollution, increasing production costs and harming the environment. Furthermore, under the demands of large-scale production, traditional preparation methods cannot meet the requirements of rapid, continuous operation processes, severely restricting production efficiency.

[0004] Therefore, we propose a magnesium oxide expanding agent preparation device. Utility Model Content

[0005] The main purpose of this utility model is to provide a magnesium oxide expanding agent mixing device to prevent concrete from cracking due to shrinkage and ensure the durability of building structures; to prevent problems such as unstable product quality, raw material spillage and pollution, increased production costs, environmental protection problems and low production efficiency caused by manual operation during the mixing process of magnesium oxide expanding agent, thereby improving the quality of concrete and the mixing efficiency and quality stability of magnesium oxide expanding agent, and effectively solving the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A magnesium oxide expanding agent preparation device includes a first support, a rotating frame rotatably connected to the inner side of the first support, a first motor fixedly installed on the outer wall of the first support, the output end of the first motor fixedly connected to the rotating frame, four storage mechanisms arranged in a ring on the inner side of the rotating frame, each storage mechanism including a storage box connected to the rotating frame via a rotating rod, a first inlet provided at the top of the storage box, a box cover installed at the top of the first inlet, a viewing window provided on one side of the storage box, and a first outlet provided at the bottom of the storage box, with an electric valve installed on the first outlet.

[0008] A conveying mechanism is provided on the inner side of the first support and below the rotating frame. A mixing mechanism is provided below the conveying mechanism away from the rotating frame. The mixing mechanism includes a mixing tank. A second feed inlet is provided at the top of the mixing tank. A flipping mechanism is rotatably connected inside the second feed inlet. The flipping mechanism includes a connecting rod. A movable concave plate is provided through the outside of the connecting rod. A weighing device is fixedly connected to the inner surface of the movable concave plate. One end of the connecting rod extends through the second feed inlet to the outside and is fixedly connected to a gear. A fixing frame is provided on the outer wall of one end of the second feed inlet. A cylinder is fixedly installed on the fixing frame. A rack is fixedly connected to the output end of the cylinder. A limiting frame that slides with the rack is fixedly connected to the outer wall of one end of the second feed inlet. The rack meshes with the gear.

[0009] By adopting the above technical solution, this dispensing device relies on the first support as a supporting structure, with a rotating frame rotatably connected to its inner side. The first motor fixed on the outer wall of the first support plays a driving role, and its output end is fixedly connected to the rotating frame. Four storage mechanisms are distributed in a circular array on the inner side of the rotating frame, which provides convenience for raw material storage. The storage box in each storage mechanism is flexibly connected to the rotating frame through a rotating rod. The first inlet at the top of the storage box is used for feeding. The box cover installed at the top ensures sealing and prevents the raw materials from being contaminated or damp. The viewing window on one side allows the operator to check the remaining amount of raw materials in the storage box at any time.

[0010] When the magnesium oxide expanding agent preparation process is started, the first motor starts and drives the rotating frame to rotate. With this rotation, the storage box containing the raw material to be discharged can be precisely rotated to the appropriate position, so that the first discharge port at the bottom is aligned with the conveying mechanism below. At the same time, the electric valve installed on the first discharge port is opened under the command of the control system according to the preset raw material ratio requirements, so that the raw material flows out smoothly from the first discharge port of the storage box and enters the conveying stage.

[0011] The conveying mechanism is located in a specific position below the rotating frame. Its core responsibility is to stably transport the raw materials flowing out of the storage box to the mixing mechanism, ensuring the continuity of the raw material conveying path.

[0012] After the raw material is conveyed to the position of the second feed inlet, the weighing device in the flipping mechanism immediately starts the working process. The weighing device is fixedly connected to the inner surface of the movable concave plate. When the raw material falls onto the weighing device, it will transmit the weight signal to the control system connected to it. Once the weight of the raw material reaches the preset value, the control system will drive the cylinder fixed on the fixed frame. The output end of the cylinder pushes the rack fixedly connected to it. Since the rack and the gear fixedly connected to one end of the connecting rod that passes through the second feed inlet and extends to the outside are meshed with each other, the gear drives the connecting rod to rotate under the push of the rack, thereby causing the movable concave plate to flip. In this way, the weighed raw material can be accurately poured into the mixing tank through the second feed inlet. During this process, the limiting frame fixedly connected to the outer wall of one end of the second feed inlet plays a key auxiliary role, ensuring that the sliding direction of the rack is accurate and that the rotation of the gear and the connecting rod is stable and smooth, laying a solid foundation for the smooth feeding of raw materials.

[0013] After the raw materials successfully enter the mixing tank, the mixing mechanism is immediately started. The agitator will fully mix the raw materials according to the set specific speed, so that the various raw materials are evenly mixed in the mixing tank. After a certain period of mixing, a magnesium oxide expander with uniform quality is finally formed to meet the needs of subsequent use.

[0014] Furthermore, the conveying mechanism includes a conveying cylinder, and a third feed inlet is fixedly connected to the upper part of the outer wall of the conveying cylinder.

[0015] By adopting the above technical solution, when the magnesium oxide expanding agent preparation process is started, the raw material in the storage box located on the rotating frame flows out through the first discharge port and enters the conveying cylinder through the third inlet.

[0016] Furthermore, a third discharge port is fixedly connected to the lower part of the outer wall of the conveying cylinder away from the third feed port.

[0017] By adopting the above technical solution, the raw materials conveyed by the conveying cylinder flow out through the third discharge port, which is precisely aligned with the second inlet of the mixing mechanism, ensuring that the raw materials can enter the mixing stage accurately and smoothly, so that the subsequent mixing operations can be smoothly connected, thereby ensuring the continuity and efficiency of the magnesium oxide expanding agent preparation process.

[0018] Furthermore, a second bracket is fixedly connected to the lower part of the outer wall of the conveying cylinder near the third discharge port.

[0019] By adopting the above technical solution, the conveyor cylinder has a certain tilt angle in order to achieve smooth material conveying, which leads to uneven distribution of its center of gravity and makes it prone to shaking or even tipping over. The second bracket, which is fixedly connected to the lower part of the outer wall near the third discharge port, provides a reliable point of force for the conveyor cylinder by contacting the ground or other supporting planes.

[0020] Furthermore, a second motor for driving the auger inside the conveying cylinder is fixedly installed at one end of the conveying cylinder.

[0021] By adopting the above technical solution, when the second motor starts, the rotational motion of the motor is directly transmitted to the auger inside the conveying drum. The auger starts to rotate, and its spiral blades will generate an axial pushing force on the raw materials entering the conveying drum, thereby conveying the raw materials.

[0022] Furthermore, the first, second, and third feed inlets are all funnel-shaped structures.

[0023] By adopting the above technical solution, the funnel-shaped structure of the first, second, and third feed inlets facilitates the receipt and introduction of raw materials.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) This utility model discloses a magnesium oxide expanding agent mixing device. Through a weighing device installed in the flipping mechanism, combined with a linkage structure consisting of gears, racks, and cylinders, the device can accurately control the input amount of each raw material. When the weight of the raw material reaches the preset value, the system automatically drives the flipping action to ensure that the raw materials are accurately poured into the mixing tank according to the predetermined ratio. Compared with traditional manual weighing and batching, this device greatly improves the batching accuracy and effectively avoids the quality problems of magnesium oxide expanding agent caused by the deviation of the raw material ratio. This allows the final product to stably exert its shrinkage and expansion regulating performance when applied to concrete, ensuring the safety of the building structure.

[0026] (2) The present invention provides a magnesium oxide expanding agent preparation device, which relies on a first support, a rotating frame and a first motor to construct a rotary storage and discharge structure, and is equipped with a conveying mechanism to realize the rapid switching and continuous conveying of raw materials. The operator only needs to start the device, and the first motor can accurately rotate the rotating frame so that the required raw material storage box is aligned with the discharge position. The electric valve opens according to the instruction to discharge the material, and the raw material quickly arrives at the mixing mechanism through the conveying mechanism. The whole process does not require frequent manual handling and weighing of raw materials, which greatly shortens the preparation cycle, meets the needs of large-scale production, and provides strong support for enterprises to increase production capacity and reduce production costs.

[0033] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0034] To prevent concrete from cracking due to shrinkage and ensure the durability of building structures; to prevent problems such as unstable product quality, raw material spillage and pollution, increased production costs, environmental impact, and low production efficiency caused by manual operation during the preparation of magnesium oxide expansive agents; and to improve the quality of concrete and the preparation efficiency and quality stability of magnesium oxide expansive agents, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a magnesium oxide expanding agent preparation device includes a first support 1, a rotating frame 2 rotatably connected to the inner side of the first support 1, a first motor 3 fixedly installed on the outer wall of the first support 1, the output end of the first motor 3 fixedly connected to the rotating frame 2, four storage mechanisms 4 arranged in a ring on the inner side of the rotating frame 2, each storage mechanism 4 including a storage box 5 connected to the rotating frame 2 via a rotating rod, a first inlet 6 provided at the top of the storage box 5, a box cover 7 installed at the top of the first inlet 6, a viewing window 8 provided on one side of the storage box 5, a first outlet 9 provided at the bottom of the storage box 5, and an electric valve installed on the first outlet 9;

[0035] A conveying mechanism 27 is provided on the inner side of the first support 1 and below the rotating frame 2. A stirring and mixing mechanism 10 is provided below the conveying mechanism 27 away from the rotating frame 2. The stirring and mixing mechanism 10 includes a stirring tank 11. A second feed inlet 12 is provided at the top of the stirring tank 11. A flipping mechanism 13 is rotatably connected inside the second feed inlet 12. The flipping mechanism 13 includes a connecting rod 18. A movable concave plate 19 is provided through the outside of the connecting rod 18. A weighing device 20 is fixedly connected to the surface inside the movable concave plate 19. One end of the connecting rod 18 extends through the second feed inlet 12 to the outside and is fixedly connected to a gear 21. A fixing frame 14 is provided on the outer wall of one end of the second feed inlet 12. A cylinder 15 is fixedly installed on the fixing frame 14. A rack 16 is fixedly connected to the output end of the cylinder 15. A limiting frame 17 that slides with the rack 16 is fixedly connected to the outer wall of one end of the second feed inlet 12. The rack 16 meshes with the gear 21.

[0036] In use, this dispensing device relies on the first support 1 as a supporting structure, with the rotating frame 2 rotatably connected to its inner side. The first motor 3, fixed to the outer wall of the first support 1, plays a driving role, and its output end is fixedly connected to the rotating frame 2. Four storage mechanisms 4 are distributed in a ring array on the inner side of the rotating frame 2, which provides convenience for raw material storage. The storage box 5 in each storage mechanism 4 is flexibly connected to the rotating frame 2 through a rotating rod. The first feed port 6 at the top of the storage box 5 is used for feeding. The box cover 7 installed at the top ensures airtightness and prevents the raw material from being contaminated or damp. The viewing window 8 on one side allows the operator to check the remaining amount of raw material in the storage box 5 at any time.

[0037] When the magnesium oxide expanding agent preparation process is started, the first motor 3 starts and drives the rotating frame 2 to rotate. With this rotation, the storage box 5 containing the raw materials to be discharged can be rotated to the appropriate position so that the first discharge port 9 at the bottom is aligned with the conveying mechanism 27 below. At the same time, the electric valve installed on the first discharge port 9 is opened under the command of the control system according to the preset raw material ratio requirements, so that the raw materials flow out smoothly from the first discharge port 9 of the storage box 5 and enter the conveying stage.

[0038] The conveying mechanism 27 is located at a specific position below the rotating frame 2. Its core function is to stably transport the raw materials flowing out of the storage box 5 to the mixing mechanism 10, ensuring the continuity of the raw material conveying path.

[0039] After the raw material is conveyed to the position of the second feed inlet 12, the weighing device 20 in the flipping mechanism 13 immediately starts its working process. The weighing device 20 is fixedly connected to the inner surface of the movable concave plate 19. When the raw material falls onto the weighing device 20, it transmits a weight signal to the control system connected to it. Once the weight of the raw material reaches the preset value, the control system drives the cylinder 15 fixed on the fixed frame 14. The output end of the cylinder 15 pushes the rack 16 fixedly connected to it. Since the rack 16 passes through the second feed inlet 12 and extends to the outside... The gear 21 fixedly connected to one end of the connecting rod 18 meshes with each other. Under the push of the rack 16, the gear 21 drives the connecting rod 18 to rotate, which in turn causes the movable concave plate 19 to flip. In this way, the weighed raw materials can be accurately poured into the mixing tank 11 through the second feed port 12. During this process, the limiting frame 17 fixedly connected to the outer wall of one end of the second feed port 12 plays a key auxiliary role, ensuring that the sliding direction of the rack 16 is accurate and that the gear 21 and the connecting rod 18 rotate stably and smoothly, laying a solid foundation for the smooth feeding of raw materials.

[0040] After the raw materials successfully enter the mixing tank 11, the mixing mechanism 10 is immediately started. The agitator will fully mix the raw materials according to the set specific speed, so that the various raw materials are evenly mixed in the mixing tank 11. After a certain period of mixing, a magnesium oxide expanding agent with uniform quality is finally formed to meet the subsequent use requirements.

[0041] For example, such as Figure 3 As shown, the present invention also includes a conveying mechanism 27 comprising a conveying cylinder 22, wherein a third feed inlet 23 is fixedly connected to the upper part of the outer wall of the conveying cylinder 22.

[0042] When in use, when the magnesium oxide expanding agent preparation process is started, the raw material in the storage box 5 located on the rotating frame 2 flows out through the first discharge port 9 and enters the conveying cylinder 22 through the third inlet port 23.

[0043] For example, such as Figure 3 As shown, the present invention also includes a third discharge port 24 fixedly connected to the lower part of the outer wall of the conveying cylinder 22 away from the third feed port 23.

[0044] In use, the raw materials conveyed by the conveying cylinder 22 flow out through the third discharge port 24. The third discharge port 24 is precisely aligned with the second feed port 12 of the mixing mechanism 10 to ensure that the raw materials can enter the mixing stage accurately, so that the subsequent mixing operations can be smoothly connected, thereby ensuring the continuity and efficiency of the magnesium oxide expansion agent preparation process.

[0045] For example, such as Figure 3 As shown, the present invention also includes a second bracket 26 fixedly connected to the lower part of the outer wall of the conveying cylinder 22 near the third discharge port 24.

[0046] When in use, the conveying cylinder 22 has a certain tilt angle in order to achieve smooth material conveying, which leads to uneven distribution of its center of gravity and makes it easy to shake or even tip over. The second bracket 26, which is fixedly connected to the lower part of the outer wall near the third discharge port 24, provides a reliable point of force for the conveying cylinder 22 by contacting the ground or other supporting planes.

[0047] For example, such as Figure 3 As shown, the present invention also includes a second motor 25 for driving the auger inside the conveying cylinder 22, which is fixedly installed at one end of the conveying cylinder 22.

[0048] When in use, after the second motor 25 is started, the rotational motion of the motor is directly transmitted to the auger inside the conveying cylinder 22. The auger starts to rotate, and its spiral blades will generate an axial pushing force on the raw materials entering the conveying cylinder 22, thereby conveying the raw materials.

[0049] For example, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the present invention also includes that the first feed inlet 6, the second feed inlet 12 and the third feed inlet 23 are all funnel-shaped structures.

[0050] When in use, the funnel-shaped structure of the first feed port 6, the second feed port 12, and the third feed port 23 facilitates the receipt and introduction of raw materials.

[0051] It should be noted that this utility model is a magnesium oxide expanding agent preparation device. The first motor 3 is started, which drives the rotating frame 2 to rotate and rotates the storage box 5 containing the raw material to be discharged to a suitable position, so that the first discharge port 9 at the bottom of the storage box 5 is aligned with the conveying mechanism 27 below. The control system commands the electric valve installed on the first discharge port 9 to open according to the preset raw material ratio requirements. The raw material flows out from the first discharge port 9 of the storage box 5 and enters the conveying cylinder 22 through the third inlet 23 of the conveying mechanism 27.

[0052] Start the second motor 25, which drives the auger inside the conveying cylinder 22 to rotate. The spiral blades of the auger generate an axial pushing force on the raw material entering the conveying cylinder 22. The raw material flows out through the third discharge port 24 of the conveying cylinder 22. The third discharge port 24 is precisely aligned with the second feed port 12 of the mixing mechanism 10, and the raw material enters the position of the second feed port 12.

[0053] The raw material falls onto the weighing device 20 inside the flipping mechanism 13. The weighing device 20 transmits the weight signal to the control system. Once the weight of the raw material reaches the preset value, the control system drives the cylinder 15 fixed on the fixed frame 14. The output end of the cylinder 15 pushes the rack 16 fixedly connected to it. The rack 16 meshes with the gear 21, which drives the gear 21 to rotate the connecting rod 18, causing the movable concave plate 19 to flip. The weighed raw material is accurately poured into the mixing tank 11 through the second feed port 12. During this process, the limit frame 17 ensures that the sliding direction of the rack 16 is accurate and that the rotation of each component is stable and smooth.

[0054] After the raw materials enter the mixing tank 11, the mixing mechanism 10 starts to operate. The agitator fully mixes the raw materials according to the set specific speed, so that the various raw materials are evenly mixed in the mixing tank 11. After a certain period of mixing, a magnesium oxide expanding agent with uniform quality is finally formed to meet the subsequent use requirements.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
