Description

Technical Field

[0001] This application relates to the field of cement production technology, and more specifically, to a cement batching device. Background Technology

[0002] The cement batching device mixes raw materials such as limestone, clay, iron powder, gypsum, and slag in proportion according to the preset formula requirements, providing qualified raw materials for subsequent calcination, grinding and other processes.

[0003] Patent CN221021690U discloses an automatic cement batching device. Cement batching workers input cement raw materials into conveying bins. Then, controlled by a microcontroller, motor one at the top of each conveying bin rotates, driving the spiral blades to transport a fixed quantity of cement raw materials through discharge pipe one to the conveyor belt inside the batching platform. Next, controlled by the microcontroller, motor two rotates, its output shaft rotating, driving the leftmost conveyor shaft to rotate. This, in turn, drives the rightmost conveyor shaft to rotate synchronously via the conveyor belt, performing the feeding operation. All the fixed quantities of cement raw materials are fed into the mixing tank through the guide plate. Controlled by the microcontroller, motor three rotates, its output shaft rotating, driving the mixing shaft and stirring blades to thoroughly mix the cement raw materials. Finally, the batched cement raw materials are discharged through the control valve of discharge pipe two. This device achieves precise quantitative output of each raw material for cement batching, accurately controls the cement batching ratio, and ensures thorough mixing of the cement batching, reducing the occurrence of poor quality due to changes in the chemical composition or segregation of raw materials.

[0004] However, in actual use, the above-mentioned batching device involves materials falling from the feed box onto the conveyor belt and then being fed into the mixing drum for mixing. Although the conveyor belt can achieve the initial material conveying connection, the materials (especially fine powder raw materials such as slag) are prone to dust generation due to vibration and airflow disturbance during the conveyor belt process, resulting in some material being scattered and lost. In addition, when the surface of the conveyor belt is uneven or there is residual material, it will cause the raw materials to adhere and accumulate, resulting in the actual amount of material entering the mixing drum being less than the theoretical batching amount, directly causing the batching ratio deviation. Summary of the Invention

[0005] The purpose of this application is to provide a cement batching device that can solve the technical problems raised in the background art.

[0030] like Figure 1-4As shown, this application provides a cement batching device, including a first support frame 1. A batching box 2 and a mixing drum 3 are arranged from top to bottom on the first support frame 1. A conveying hopper 4 is provided between the batching box 2 and the mixing drum 3. The inlet end of the conveying hopper 4 is connected to the outlet of the batching box 2, and the outlet end of the conveying hopper 4 is connected to the inlet of the mixing drum 3. The conveying hopper 4 is mounted on a second support frame 5, and a vibration component 6 is provided on the conveying hopper 4. When the cement batching device is working, the first support frame 1 provides stable support for the overall structure. The material in the batching box 2 enters the inlet end of the conveying hopper 4 through the outlet of the batching box 2. The conveying hopper 4, fixed by the second support frame 5, guides and conveys the material, ensuring that the material accurately enters the inlet of the mixing drum 3 through the outlet end of the conveying hopper 4. Simultaneously, the conveying... The vibration component 6 on the feeding hopper 4 operates, continuously vibrating to prevent material from stagnating or bridging in the conveying hopper 4, ensuring that the material can be smoothly and continuously conveyed from the batching box 2 to the mixing tank 3 for mixing. The batching device of this application sets the batching box 2 and the mixing tank 3 from top to bottom on the first support frame 1, and uses the conveying hopper 4 to directly connect the inlet and outlet of the two, eliminating the traditional conveyor belt transfer link. The vibration component 6 on the conveying hopper 4 can effectively prevent the material from clogging or bridging during the conveying process, reducing the loss and residue of the material during the conveying process. This ensures the smoothness and continuity of the material conveying, improves the batching accuracy, and at the same time, the overall structure is compact, reducing the floor space occupied, and the coordinated cooperation of each component improves the overall efficiency of cement batching.

[0031] like Figure 2-4 As shown, the batching box 2 is provided with multiple receiving cavities 21. Each receiving cavity 21 has a discharge port at its bottom and a conveying component 7 at the discharge port. The multiple receiving cavities 21 in the batching box 2 can store different types of cement raw materials. When the batching operation is carried out, the discharge port at the bottom of each receiving cavity 21 is controlled by the corresponding conveying component 7 to output raw materials according to the preset formula requirements. By adjusting the operating status of the conveying component 7 (such as start / stop and conveying speed), the quantitative release of different raw materials is realized, providing raw materials in proportion for the subsequent mixing process.

[0032] like Figure 2-4As shown, the material conveying assembly 7 includes a rotating shaft 71, a spiral blade 72, and a conveying motor 73. The rotating shaft 71 is rotatably mounted at the discharge port, the spiral blade 72 is fixed on the rotating shaft 71 and located inside the discharge port, and the conveying motor 73 is fixed on the batching box 2. One end of the rotating shaft 71 extends outside the discharge port and is connected to the output shaft of the conveying motor 73. When the material conveying assembly 7 is working, after the conveying motor 73 starts, it drives the rotating shaft 71 connected to its output shaft to rotate at the discharge port. The spiral blade 72 fixed on the rotating shaft 71 rotates synchronously with the rotating shaft 71. By using the spiral pushing action of the spiral blade 72, the material in the receiving cavity 21 is stably conveyed out along the discharge port. By controlling the start, stop, and speed of the conveying motor 73, the conveying amount and conveying speed of the material can be precisely controlled.

[0033] like Figure 1 and Figure 4 As shown, the top of the conveying hopper 4 is provided with a matching sealing cover 41, and a clearance hole 42 is provided on one side of the conveying hopper 4. The discharge port of the batching box 2 extends into the conveying hopper 4 through the clearance hole 42. A dustproof cloth 8 is provided between the clearance hole 42 and the discharge port. The discharge end of the conveying hopper 4 is connected to the inlet of the mixing tank 3 through a hose 9. The cooperation between the sealing cover 41 and the dustproof cloth 8 effectively blocks the spread of dust during the material conveying process, improves the production environment and reduces material loss. The connection method of the hose 9 enhances the installation adaptability between the conveying hopper 4 and the mixing tank 3, and can alleviate the hard impact caused by equipment vibration. In actual use, the inner side of the sealing cover 41, the inner wall of the conveying hopper 4 and the inner side of the dustproof cloth 8 are all coated with an anti-stick coating (Teflon coating or nano anti-stick coating, etc.), which can reduce the adhesion of material dust on the inner side of the sealing cover 41, the inner wall of the conveying hopper 4 and the dustproof cloth 8.

[0034] like Figure 3 As shown, the vibration assembly 6 includes a vibration motor 61 and a mounting base 62. The vibration motor 61 is connected to the conveying hopper 4 through the mounting base 62. Specifically, the mounting base 62 is fixed on the conveying hopper 4, and the vibration motor 61 is fixed on the mounting base 62. When the vibration motor 61 is working, the vibration force generated is transmitted to the conveying hopper 4 through the mounting base 62, causing the conveying hopper 4 to vibrate continuously. The impact force generated by the vibration breaks the adsorption and cohesion between materials and between materials and the inner wall of the conveying hopper 4, promoting the smooth flow of materials in the conveying hopper 4 and preventing material stagnation or blockage. The mounting base 62 can be a rubber pad, which can not only ensure the effective transmission of the vibration force of the vibration motor 61 to prevent material adhesion and blockage, but also use its elasticity to buffer the vibration impact, reduce the impact wear of the vibration motor 61 on the conveying hopper 4, and extend the service life of the equipment.

[0035] like Figure 3As shown, a stirring assembly 10 is provided inside the stirring tank 3. The stirring assembly 10 includes a drive motor 101, a stirring shaft 102, and multiple stirring rods 103. The drive motor 101 is fixed to the top of the stirring tank 3. The stirring shaft 102 is rotatably disposed inside the stirring tank 3. The upper end of the stirring shaft 102 extends to the outside of the stirring tank 3 and is connected to the output shaft of the drive motor 101. Multiple stirring rods 103 are evenly fixed on the stirring shaft 102. A bearing is provided at the connection between the stirring shaft 102 and the stirring tank 3. After the drive motor 101 is started, its output shaft drives the stirring shaft 102 to rotate inside the stirring tank 3. The multiple stirring rods fixed on the stirring shaft 102 rotate synchronously with the stirring shaft 102, so that the materials are mixed under the action of stirring force.

[0036] like Figure 3 As shown, there are two stirring components 10. The stirring shafts 102 of the two stirring components 10 are symmetrically arranged, and the stirring rods 103 of the two stirring components 10 are staggered vertically, which can form a three-dimensional cross stirring effect on the material in the barrel, thereby enhancing the stirring effect. The two stirring components 10 stir at the same time, and with the staggered stirring rods 103, the stirring range is expanded and the stirring efficiency is improved.

[0037] like Figure 3 As shown, the bottom of the mixing tank 3 is provided with a discharge port, and an electric valve 11 is provided at the discharge port. The discharge of materials in the mixing tank 3 is controlled by opening and closing the electric valve 11.

[0038] The cement batching device of this application also includes a microcontroller (not shown in the figure), which is externally powered and electrically connected to the conveyor motor 73, the drive motor 101, the vibrating motor 61, and the electric valve 11. The microcontroller centrally controls the operating status of each component, such as controlling the start and stop and speed of the conveyor motor 73 to adjust the raw material conveying amount, controlling the drive motor 101 to drive the mixing assembly 10, controlling the start of the vibrating motor 61 to prevent material blockage, and controlling the opening and closing of the electric valve 11 to complete the discharge.

[0039] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
