Description

Technical Field

[0001] This invention belongs to the field of cement preparation technology, specifically a device for preparing cement-based polymers. Background Technology

[0002] Soil-based cement is a novel alkali-activated cementitious material. Its development stems from a profound reflection on the performance defects of traditional silicate cement and the urgent need for the resource utilization of industrial solid waste. In the 1930s, Purdon in the United States first proposed the "alkali activation" theory while studying the hardening mechanism of cement, discovering that NaOH could catalyze the dissolution and repolymerization of silica-alumina compounds in cement. Subsequently, Soviet scholars systematically studied the activation effects of various alkali metal salts such as hydroxides, carbonates, and silicates, and initially applied this technology to construction engineering in the 1960s.

[0003] For example, the invention disclosed in CN222553873U discloses a device for preparing retarded silicate cement, which includes a batching tank with an inlet at the front end and a motor on the side. The output shaft of the motor is fixedly connected to a rotating shaft. The inside of the batching tank is equipped with an up-and-down stirring mechanism and a striking mechanism. The up-and-down stirring mechanism includes a fixed plate, a bevel gear B, and a rotating gear. A rotating rod is rotatably connected through the top of the fixed plate, and a slide cylinder is slidably connected to the surface of the rotating rod. By setting up the up-and-down stirring mechanism, this invention achieves the effect that when the motor drives the rotating shaft to rotate, the bevel gear B, bevel gear A, rotating gear, hydraulic chamber, and other components work together to drive the slide cylinder to rotate while repeatedly moving up and down, so that the stirring paddle can completely stir the contents of the batching tank and improve the stirring effect.

[0004] While the aforementioned comparative documents achieve complete mixing in the batching tank and improve the mixing effect, they cannot ensure the precise addition of each raw material according to the set ratio. Errors in the ratio will directly lead to a series of quality problems such as incomplete hydration reaction, unstable strength development, and uncontrolled setting time. Therefore, a soil-based cement preparation device is proposed to address these issues. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, the present invention proposes a soil-based cement preparation device.

[0006] The technical solution adopted by the present invention to solve its technical problem is: the present invention provides a soil-based cement preparation device, including a preparation barrel, a crushing component is provided at the top of the preparation barrel, a stirring component is provided inside the preparation barrel, and a metering feeding component is provided on both sides of the top of the preparation barrel. The quantitative feeding component includes an L-shaped support plate fixedly connected to the side of the preparation barrel, a rectangular shell fixedly connected to the side of the L-shaped support plate, a feeding pipe fixedly connected to the top of the rectangular shell, a transfer plate slidably connected inside the rectangular shell, a feeding hole opened at the bottom of the inside of the rectangular shell, a guide frame fixedly connected to the bottom of the rectangular shell, an electric telescopic rod assembled on the side of the rectangular shell, and a drive rod fixedly connected to the telescopic end of the electric telescopic rod.

[0007] Preferably, the end of the drive rod away from the electric telescopic rod is fixedly connected to the side of the transfer plate, and the two sets of guide frames are located above the crushing component.

[0008] Preferably, the rectangular shell has a guide groove on its side, and the driving rod is slidably connected inside the guide groove.

[0009] Preferably, the guide frame is located below the discharge hole, and the discharge pipe is connected to the rectangular shell.

[0010] Preferably, the transfer plate has a through-hole for storing material, and the diameter of the discharge hole matches the diameter of the storage trough.

[0011] Preferably, the transfer plate is slidably connected inside the rectangular shell, and the discharge hole is located on the movement trajectory of the transfer plate.

[0012] The beneficial effects of this invention are: This invention provides a device for preparing terephthalic acid cement. An electric telescopic rod drives a sliding transfer plate. When the storage trough aligns with the discharge hole at the bottom of the rectangular shell, the raw materials in the storage trough fall through the discharge hole and are guided along the guide frame to the crushing component, thereby crushing lumps or large particles. The crushed raw materials fall to the bottom of the preparation tank. At this time, the agitator is activated to fully mix the various powders in the preparation tank. The quantitative discharge components on both sides work independently, allowing for separate control of the discharge amount of different raw materials. By controlling the extension frequency or stroke of the electric telescopic rod, precise control of the discharge amount can be achieved, as well as accurate proportioning and continuous operation, significantly improving preparation efficiency and finished product quality.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Specific implementation examples are given below.

[0017] Please see Figures 1-4 The present invention provides a soil-based cement preparation device, including a preparation barrel 1, a crushing component 2 is provided at the top of the preparation barrel 1, a stirring component 3 is provided inside the preparation barrel 1, and a quantitative feeding component 4 is provided on both sides of the top of the preparation barrel 1. The quantitative feeding component 4 includes an L-shaped support plate 401 fixedly connected to the side of the preparation barrel 1. A rectangular shell 402 is fixedly connected to the side of the L-shaped support plate 401. A feeding pipe 403 is fixedly connected to the top of the rectangular shell 402. A transfer plate 404 is slidably connected inside the rectangular shell 402. A feeding hole 405 is opened at the bottom of the rectangular shell 402. A guide frame 406 is fixedly connected to the bottom of the rectangular shell 402. An electric telescopic rod 409 is assembled on the side of the rectangular shell 402. A drive rod 408 is fixedly connected to the telescopic end of the electric telescopic rod 409.

[0018] During operation, the powder first falls into the storage tank 410 of the transfer plate 404. When it is full, it is a fixed volume of one unit. The transfer plate 404 is pulled horizontally by the electric telescopic rod 409. The storage tank 410 filled with material is moved to the discharge hole 405. The material falls into the crushing component 2 by gravity through the discharge hole 405 and the guide frame 406. Each time the transfer plate 404 is pushed, the amount of material discharged is constant, realizing quantitative feeding by volume. There is no need to equip it with an electronic scale or flow meter. The structure is simple and the cost is low. The stirring component 3 is composed of a set of motors and stirring rods. The motors are fixedly connected to the bottom of the preparation tank 1, and the output shaft of the motors is fixedly connected to the stirring rods.

[0019] Furthermore, such as Figures 1-4 As shown, the end of the driving rod 408 away from the electric telescopic rod 409 is fixedly connected to the side of the material transfer plate 404. Two sets of guide frames 406 are located above the crushing component 2. A guide groove 407 is provided on the side of the rectangular shell 402, and the driving rod 408 is slidably connected inside the guide groove 407.

[0020] During operation, there is a set of quantitative feeding components 4 on each side of the top of the preparation barrel 1. Each feeding component has a guide frame 406 at the bottom. The outlet of the guide frame 406 is suspended directly above the inlet of the crushing component 2. The guide groove 407 provides a fixed motion track for the driving rod 408, which ensures that the transfer plate 404 can only slide in a straight line inside the rectangular shell 402, and will not get stuck or deflected due to uneven resistance, thereby driving the transfer plate 404 inside the rectangular shell 402 to slide back and forth.

[0021] Furthermore, such as Figures 1-4 As shown, the guide frame 406 is located below the discharge hole 405, the discharge pipe 403 is connected to the rectangular shell 402, and the transfer plate 404 has a storage groove 410 through it. The diameter of the discharge hole 405 matches the diameter of the storage groove 410. The transfer plate 404 is slidably connected to the inside of the rectangular shell 402, and the discharge hole 405 is located on the movement trajectory of the transfer plate 404.

[0022] During operation, the rectangular shell 402 serves as the outer casing, inside which the transfer plate 404 moves. The feeding pipe 403 is responsible for feeding materials into this outer casing. Simultaneously, a storage trough 410 is formed through the interior of the transfer plate 404. The transfer plate 404 is a single plate with a through-hole in the middle; this hole is the storage trough 410. Meanwhile, the crushing component 2 consists of two sets of crushing rollers. One set of crushing rollers is connected to a motor, which drives the other set of crushing rollers to rotate. Gears are fixedly connected to the outer sides of both sets of crushing rollers, and the two sets of gears mesh. Therefore, when one set of crushing rollers rotates, it drives one set of gears to rotate, which in turn drives the other set of gears and its other set of crushing rollers to rotate. Thus, the crushing component 2 crushes and grinds raw materials with lumps or large particles, processing them into fine powder that meets the requirements, providing good conditions for subsequent uniform mixing. Working principle: When adding raw materials to the preparation tank 1, the raw materials are first injected into the rectangular shell 402 through the feeding pipe 403. After falling in, the raw materials fill the storage trough 410 on the transfer plate 404. At this time, the electric telescopic rod 409 can be activated. Its telescopic end can push the transfer plate 404 to slide inside the rectangular shell 402 through the driving rod 408. When the storage trough 410 moves to align with the feeding hole 405 at the bottom of the rectangular shell 402, the raw materials in the storage trough 410 fall through the feeding hole 405 and are concentrated and guided to the crushing component 2 along the guide frame 406. At the same time, by controlling the extension frequency or stroke of the electric telescopic rod 409, the precise control of the feeding amount can be achieved. The quantitative raw materials fall into the crushing component 2 at the top of the preparation tank 1 through the guide frame 406. The crushing component 2 consists of two sets of crushing rollers. The process involves a set of crushing rollers connected to a motor, which drives the rollers to rotate. Gears are fixedly connected to the outer sides of both sets of rollers, and the two sets of gears mesh. Therefore, when one set of rollers rotates, it drives the gears to rotate, which in turn drives the other set of gears and its other set of rollers to rotate. Thus, the crushing component 2 crushes and grinds the raw materials that are agglomerated or have large particles, processing them into fine powder that meets the requirements. This provides good conditions for subsequent uniform mixing. The crushed raw materials fall to the bottom of the preparation tank 1. At this time, the agitator 3 is activated to fully stir the various powders in the preparation tank 1, making them evenly mixed, and finally forming the finished cementitious product. Throughout the process, the metering feeders 4 on both sides work independently, which can control the amount of different raw materials fed, achieving precise proportioning and continuous operation, significantly improving preparation efficiency and finished product quality.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
