Description

Technical Field

[0001] This utility model relates to the field of mixing and stirring devices, and in particular to a mixing and stirring device for pretreatment of raw materials for GRC products. Background Technology

[0002] GRC products, or glass fiber reinforced concrete products, are highly favored in the modern building materials industry due to their advantages such as lightweight, high strength, excellent durability, and good plasticity. In the production process of GRC products, the pretreatment of raw materials is a crucial step, and the mixing device is the core equipment for this step. Its performance directly affects the quality and production efficiency of the GRC products.

[0003] However, in practical use, existing stirring and mixing devices have many shortcomings.

[0004] On the one hand, it is difficult to guarantee the uniformity of mixing different types of raw materials. For example, when mixing glass fiber and concrete matrix, due to the large differences in their properties, traditional mixing equipment is unable to mix them thoroughly, resulting in uneven internal composition of GRC products, which affects the strength and stability of the products.

[0005] On the other hand, some mixing devices lack the function of pre-processing raw materials. For example, some raw materials with lumps or large particles cannot be effectively crushed before mixing. This not only reduces the mixing efficiency, but may also damage the internal structure of the mixing device due to the presence of large pieces of material, affecting the service life of the equipment. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a stirring and mixing device for pretreatment of raw materials for GRC products, which overcomes the shortcomings of the prior art and effectively solves the problems of difficulty in ensuring the uniformity of stirring and mixing and lack of pretreatment function for raw materials in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A mixing device for pretreatment of raw materials for GRC products includes a box body. A first spiral conveying rod is rotatably connected to the bottom of the box body, and a second spiral conveying rod is rotatably connected to the bottom of the box body on both sides of the first spiral conveying rod. A bracket is fixed to the outer wall of the box body, and a fixed frame is fixed to both ends of the top of the bracket. A screw is rotatably connected to the inner walls of the upper and lower ends of one of the fixed frames, and a guide rod is welded to the inner walls of the upper and lower ends of the other fixed frame. A driving mechanism is connected between the screw and the guide rod. The driving mechanism includes a connecting plate, a rotating shaft rotatably connected to the bottom of the connecting plate at equal distances, a first gear sleeved and fixed to the bottom end of the rotating shaft, a second gear meshing between two adjacent first gears, a rotating rod fixed to the top of the second gear, and a U-shaped frame rotatably connected to the top of the rotating rod. A crushing mechanism is connected to one side of the box body, and the crushing mechanism includes a crushing box, a crushing roller rotatably connected to the crushing box, a guide groove inserted and fixed to the bottom of the outer wall of one side of the crushing box, and a support frame welded and fixed to both ends of the bottom of the crushing box.

[0009] Preferably, a discharge pipe is inserted and fixed to the bottom of the box, and a solenoid valve is installed on the discharge pipe.

[0010] Preferably, the spiral directions of the first spiral conveyor rod and the second spiral conveyor rod are opposite, and a hexagonal block is fixed to the top of both the first spiral conveyor rod and the second spiral conveyor rod.

[0011] Preferably, a servo motor is installed on the top of one of the fixing frames and the top of the connecting plate, and the output shafts of the two servo motors are respectively connected and fixed to the top of the screw and one of the rotating shafts via couplings.

[0012] Preferably, the U-shaped frame is fixed to the bottom of the connecting plate, and the bottom of the rotating shaft is provided with a hexagonal groove that can be inserted into the hexagonal block.

[0013] Preferably, one top end of the connecting plate is screwed to the screw rod, and the other top end of the connecting plate is slidably connected to the guide rod, so that the connecting plate and the top of the box form a sealed fit.

[0014] Preferably, the bottom end of the feed trough is inserted and fixed to one side of the outer wall of the box, and a drive motor is installed and fixed on one side of the outer wall of the crushing box. The output shaft of the drive motor is connected and fixed to one end of one of the crushing rollers through a coupling. The other ends of the two crushing rollers are fitted and fixed with a third gear that is set outside the crushing box and meshes with each other.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. By setting up a first spiral conveyor and a second spiral conveyor with opposite spiral directions, a unique material flow path can be formed during the mixing process. When the first spiral conveyor pushes the material upward, the second spiral conveyor pushes the material downward, causing strong convection and mixing effects inside the box, which greatly improves the uniformity of mixing, ensures that the raw materials of GRC products can be fully mixed, and improves product quality;

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example:

[0025] Reference Figure 1-4 A mixing device for pretreatment of raw materials for GRC products includes a housing 1. A first spiral conveying rod 3 is rotatably connected to the bottom of the housing 1. Second spiral conveying rods 4 are rotatably connected to the bottom of the housing 1 on both sides of the first spiral conveying rod 3. A bracket 6 is fixed to the outer wall of the housing 1. Fixing frames 7 are fixed to both ends of the top of the bracket 6. A screw 8 is rotatably connected to the inner walls of the upper and lower ends of one fixing frame 7. A guide rod 9 is welded to the inner walls of the upper and lower ends of the other fixing frame 7. A driving mechanism 10 is connected between the screw 8 and the guide rod 9. The driving mechanism 10 includes a connecting plate 11. A rotating shaft 13 is equidistantly rotatably connected to the bottom of the connecting plate 11; a first gear 14 is sleeved and fixed to the bottom end of the rotating shaft 13; a second gear 15 is meshed between two adjacent first gears 14; a rotating rod 16 is fixed to the top of the second gear 15; and a U-shaped frame 17 is rotatably connected to the top end of the rotating rod 16. A crushing mechanism 18 is connected to one side of the box body 1. The crushing mechanism 18 includes a crushing box 19; a crushing roller 20 that is meshed and rotatably connected to the crushing box 19; a guide groove 22 that is inserted and fixed to the bottom of the outer wall of one side of the crushing box 19; and a support frame 23 that is welded and fixed to both ends of the bottom of the crushing box 19.

[0026] A discharge pipe 2 is fixedly inserted into the bottom of the housing 1, and a solenoid valve is installed on the discharge pipe 2. The solenoid valve on the discharge pipe 2 at the bottom of the housing 1 allows for precise control of the timing and amount of material discharge after mixing, facilitating subsequent production operations. The first spiral conveyor rod 3 and the second spiral conveyor rod 4 have opposite spiral directions, and both have hexagonal blocks 5 fixed to their tops. When different types of raw materials need to be mixed, the first spiral conveyor rod 3 and the second spiral conveyor rod 4 are driven to rotate by a motor. Due to the opposite spiral directions, they can create an upward and downward convection mixing effect of the material inside the housing 1. The hexagonal blocks 5 on the top facilitate the subsequent connection of the drive mechanism 10, allowing the drive mechanism 10 to drive the spiral conveyor rods to rotate more stably.

[0027] One of the fixed brackets 7 and the top of the connecting plate 11 are each equipped with a servo motor 12. The output shafts of the two servo motors 12 are respectively connected and fixed to the top of the screw 8 and one of the rotating shafts 13 via couplings. The U-shaped bracket 17 is fixed to the bottom of the connecting plate 11, and the bottom of each rotating shaft 13 is provided with a hexagonal groove that forms an insertion fit with the hexagonal block 5. One end of the top of the connecting plate 11 is screwed to the screw 8, and the other end of the top of the connecting plate 11 is slidably connected to the guide rod 9. The connecting plate 11 and the top of the housing 1 form a sealed fit. The fixed brackets 7 at both ends of the top of the bracket 6 have screws 8 rotatably connected to the inner walls of the upper and lower ends of one fixed bracket 7, and guide rods 9 are welded and fixed to the inner walls of the upper and lower ends of the other fixed bracket 7. A drive mechanism 10 is connected between the screw 8 and the guide rod 9. One end of the top of the connecting plate 11 in the drive mechanism 10 is screwed to the screw 8, and the other end is slidably connected to the guide rod 9. When the servo motor 12 drives the screw 8 to rotate, the connecting plate 11 is screwed to the screw 8 and slidably connected to the guide rod 9. Under the limiting action of the threaded transmission and the guide rod 9, the connecting plate 11 can move up and down along the direction of the guide rod 9. The rotating shaft 13, which is equidistantly connected to the bottom of the connecting plate 11, can transmit power to the hexagonal block 5 at the top of the screw conveyor rod through the meshing transmission of the first gear 14 and the second gear 15 during rotation, thereby driving the screw conveyor rod to rotate. The fixed frame 7 and the servo motor 12 installed on the top of the connecting plate 11 provide power for the rotation of the screw 8 and the rotating shaft 13, respectively. By controlling the speed and direction of the servo motor 12, the rotation speed and direction of the screw conveyor rod can be flexibly adjusted to adapt to the mixing requirements of different raw materials. The U-shaped frame 17 is fixed to the bottom of the connecting plate 11, and the bottom of the rotating shaft 13 has a hexagonal groove that forms an interlocking fit with the hexagonal block 5. When the connecting plate 11 moves downward under the action of the screw 8 and the guide rod 9, the hexagonal groove at the bottom of the rotating shaft 13 can accurately engage with the hexagonal block 5 at the top of the screw conveyor, ensuring that the power can be stably transmitted from the rotating shaft 13 to the screw conveyor, achieving efficient mixing. The connecting plate 11 and the top of the box 1 form a sealed fit, which can effectively prevent materials from splashing out of the box 1 during the mixing process, ensuring a clean mixing environment, avoiding material loss, and ensuring the accuracy and integrity of the mixing.

[0028] The bottom end of the feed chute 22 is inserted and fixed to one side of the outer wall of the box 1. A drive motor 21 is installed and fixed to one side of the outer wall of the crushing box 19. The output shaft of the drive motor 21 is connected and fixed to one end of one of the crushing rollers 20 through a coupling. The other ends of both crushing rollers 20 are fitted with and fixed to a third gear that is set outside the crushing box 19 and meshes with each other. The bottom ends of both support frames 23 are welded and fixed to the bracket 6. When the raw materials need to be pre-treated, the drive motor 21 is started. The drive motor 21 drives one of the crushing rollers 20 to rotate. Through the meshing transmission of the third gear, the other crushing roller 20 also rotates in the opposite direction. At this time, the raw materials to be crushed are placed into the crushing box 19. Under the mutual squeezing and shearing action of the two crushing rollers 20, the raw materials are crushed into fine particles, and then enter the box 1 through the guide chute 22 for subsequent stirring and mixing operations.

[0029] Working principle:

[0030] When using the mixing and stirring device for pre-treatment of raw materials for GRC products, first, place the various raw materials required for GRC products, such as cement, glass fiber, and aggregates, into the crushing box 19 of the crushing mechanism 18. Start the drive motor 21 of the crushing mechanism 18, which drives one of the crushing rollers 20 to rotate. Since the two crushing rollers 20 are connected by an externally meshing third gear, the other crushing roller 20 will also rotate in the opposite direction. Under the mutual squeezing and shearing action of the two crushing rollers 20, the raw materials are crushed into fine particles, which enter the interior of the box 1 through the feed chute 22.

[0031] Meanwhile, according to the mixing requirements, the servo motor 12 on the bracket 6 is activated. One of the servo motors 12 drives the screw 8 to rotate. Since the connecting plate 11 is screwed to the screw 8 and slidably connected to the guide rod 9, under the limiting action of the threaded transmission and the guide rod 9, the connecting plate 11 will move up and down along the direction of the guide rod 9. When the connecting plate 11 moves downward, the first gear 14 and the second gear 15 on its bottom rotating shaft 13 mesh with each other, transmitting power to the hexagonal block 5 at the top of the spiral conveyor rod, driving the first spiral conveyor rod 3 and the second spiral conveyor rod 4 to rotate. Since the spiral directions of the first spiral conveyor rod 3 and the second spiral conveyor rod 4 are opposite, during the rotation, they will drive the material to form an upward and downward convection mixing effect inside the box 1, so that the material can be fully and evenly mixed.

[0032] During the mixing process, the rotation speed and direction of the screw conveyor can be flexibly adjusted by controlling the speed and direction of the servo motor 12 to meet the mixing requirements of different raw materials. After mixing is completed, the solenoid valve on the discharge pipe 2 at the bottom of the box 1 is opened, and the evenly mixed material is discharged from the box 1 for subsequent production of GRC products. Throughout the entire process, the raw materials are pre-treated by the crushing mechanism 18, which improves the mixing efficiency and product quality. At the same time, the unique mixing structure ensures thorough mixing of the materials, achieving efficient and high-quality pre-treatment mixing of GRC product raw materials.

[0033] 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.
