Description

Technical Field

[0001] This utility model relates to the field of cement production technology, and in particular to a cement batching device for a cement production line. Background Technology

[0002] Cement is a powdery hydraulic inorganic binder that, when mixed with water, forms a paste that hardens in air or, even better, in water, effectively binding materials such as sand and stone together. Early mixtures of lime and volcanic ash were very similar to modern lime-volcanic ash cement. Concrete made from this binder, using it to bind crushed stone, not only achieved high strength after hardening but also resisted erosion from both fresh and salt water. For a long time, it has been widely used as an important binder in civil engineering, water conservancy, and national defense projects.

[0003] Cement batching refers to mixing cement and other ingredients together. Most cement production lines currently use mixing equipment that employs agitators to stir the cement, as follows:

[0004] A search revealed a patent with authorization announcement number CN220499550U, which discloses a cement batching device for a cement production line. The device includes a batching box containing a mixing structure and multiple sets of cleaning structures. The mixing structure includes a motor mounted on the upper wall of the batching box, with a rotating shaft connected to the motor's drive end. Multiple sets of stirring rods are mounted on the rotating shaft, arranged from top to bottom. Each set of cleaning structures includes a pair of scrapers located on the upper and lower sides of the stirring rods, sliding through the side wall of the batching box. This invention features a reasonable structure and novel design. The mixing structure effectively mixes cement materials, while the auger on the rotating shaft facilitates discharge, preventing cement blockage at the discharge port. The cleaning structures allow for easy cleaning of the stirring rods without manual intervention, saving time and effort. Furthermore, the side wall cleaning structures facilitate cleaning of the inner wall of the batching box.

[0005] However, the cement batching device in the above-mentioned cement production line still has the following areas for optimization. For example, its mixing mechanism is a fixed design, which results in many dead zones in the mixing of raw materials inside the batching box, leading to poor mixing uniformity and reducing the quality of cement production. In addition, although theoretically the mixing rod and the inner wall of the batching box can be cleaned by scrapers and cleaning plates respectively, solidified cement may also adhere to the ends of the scrapers and the bottom of the cleaning plates. Since the scrapers and cleaning plates are not easy to disassemble, this cement cannot be cleaned off effectively. Over time, this will affect the production of cement in the next round. Therefore, there is an urgent need for a cement batching device for a cement production line to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model discloses a cement batching device for a cement production line. It is equipped with a stirring mechanism, allowing the raw materials required for cement production to be added to the mixing tank through a feed hopper during operation. Then, a reduction motor is activated, driving the rotating shaft and stirring rods to rotate, thereby mixing the cement raw materials inside the mixing tank. Simultaneously, an electric cylinder is activated, reciprocating within a set range, which in turn moves the top seat and mounting base up and down, further driving the rotating shaft and multiple sets of stirring rods to move up and down within a certain range. Therefore, it effectively reduces dead zones in the mixing tank and improves the mixing efficiency. The uniformity of the cement production process is improved, thus enhancing the overall quality. After cement production, the electric cylinder can be activated to extend to its maximum length, causing the top seat to move upwards. This, in turn, moves the mounting base, rotating shaft, and stirring rod upwards until they are all outside the mixing tank. This allows for thorough cleaning of the rotating shaft, stirring rod, and the inner wall of the mixing tank using an external high-pressure water gun. The cleaning effect is excellent. After cleaning, the rotating shaft and stirring rod can be reset, minimizing disruption to the next round of cement production. In summary, this addresses the problems mentioned in the background technology.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model discloses a cement batching device for a cement production line, including a base. The top of the base has two horizontally opened grooves, and a sliding seat is slidably installed at the two grooves through a sliding connector. The sliding seat is U-shaped. A mixing tank is fixedly mounted on the top of the base. The mixing tank is located in the groove of the sliding seat. The top of the mixing tank is open. A feed hopper and a discharge pipe with a valve mechanism are provided on one side of the mixing tank.

[0009] A stirring mechanism includes an electric cylinder, which is fixedly installed in a through-type manner at a slide. A top seat is fixedly connected to the telescopic end of the electric cylinder. A mounting seat is fixedly connected to the bottom of the top seat through multiple connecting rods. A geared motor is fixedly installed at the mounting seat. The output end of the geared motor passes through the mounting seat and is fixedly connected to a rotating shaft. Multiple sets of stirring rods are provided outside the rotating shaft, and all sets of stirring rods are located inside the stirring tank.

[0010] A drive mechanism is located on top of the base and connected to the slide.

[0011] Furthermore, the slide block is fixedly connected with two telescopic support rods in a through-type manner. The telescopic ends of the telescopic support rods are fixedly connected to the bottom of the top block, and the two telescopic support rods are respectively close to the front and rear sides of the slide block. The two telescopic support rods and the electric cylinder are designed with an isosceles triangle distribution.

[0012] Furthermore, multiple guide rods are movably mounted through the mounting base, and a cover is fixedly connected to the bottom of the multiple guide rods. A through groove is opened in the center of the cover, and the size of the through groove is larger than the size of the rotating shaft. The bottom of the cover fits against the top opening of the mixing tank.

[0013] Furthermore, a spring is mounted on the outer side of the guide rod, and the two ends of the spring are fixedly connected to the mounting base and the cover, respectively.

[0014] Furthermore, a sealing gasket layer is attached to the bottom of the cover, and the sealing gasket layer is made of rubber material.

[0015] Furthermore, the multiple guide rods are arranged in a ring array, and the top of each guide rod is fixedly connected to a limiting block.

[0016] Furthermore, the driving mechanism includes a cylinder, which is fixedly mounted on the top of the base by a mounting component. A transmission plate is fixedly connected to the telescopic end of the cylinder, and the top of the transmission plate is fixedly connected to the bottom of the slide.

[0017] The present invention has the following advantages over the prior art:

[0018] 1. This technical solution incorporates a mixing mechanism, allowing the raw materials required for cement production to be added to the mixing tank via the feed hopper during operation. The mixing mechanism then mixes the cement materials inside the tank. The rotating shaft and mixing rod within the mixing mechanism can move up and down, effectively reducing dead zones in the mixing tank and improving the uniformity of mixing, thus enhancing the quality of cement production. After cement production is complete, the electric cylinder in the mixing mechanism can be activated, moving the mounting base, rotating shaft, and mixing rod to the outside of the mixing tank. This allows for cleaning of the rotating shaft, mixing rod, and the inner wall of the mixing tank using an external high-pressure water gun. The cleaning effect is good. After cleaning, the rotating shaft and mixing rod can be reset, minimizing disruption to the next round of cement production. This design demonstrates high practicality.

[0019] 2. This technical solution incorporates a drive mechanism, allowing the electric cylinder to be activated first, moving the rotating shaft and stirring rod upwards to the outside of the mixing tank during cleaning. Then, the drive mechanism moves the sliding block, causing the rotating shaft and stirring rod to move laterally away from the mixing tank. At this point, the rotating shaft, stirring rod, and the interior of the mixing tank can be cleaned. Because the rotating shaft and stirring rod are positioned away from the top of the mixing tank, it facilitates cleaning of the inner wall of the tank and effectively prevents accidental activation of the rotating shaft and stirring rod, thus reducing safety hazards during cleaning. This significantly improves the convenience and safety of the cleaning process, making it highly practical. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0031] Reference Figures 1-5 A cement batching device for a cement production line includes a base 1. Two horizontal grooves 2 are provided on the top of the base 1. Slide seats 3 are slidably installed on the two grooves 2 through sliding connectors. The slide seats 3 are U-shaped. A mixing tank 4 is fixedly mounted on the top of the base 1. The mixing tank 4 is located in the groove of the slide seat 3. The top of the mixing tank 4 is designed to be open. A feed hopper 5 and a discharge pipe 6 with a valve mechanism are provided on one side of the mixing tank 4.

[0032] The stirring mechanism 7 includes an electric cylinder 702, which is fixedly installed through the slide 3. The telescopic end of the electric cylinder 702 is fixedly connected to a top seat 703. The bottom of the top seat 703 is fixedly connected to a mounting base 705 via multiple connecting rods 704. A reduction motor 706 is fixedly installed at the mounting base 705. The output end of the reduction motor 706 passes through the mounting base 705 and is fixedly connected to a rotating shaft 707. Multiple sets of stirring rods 708 are provided on the outside of the rotating shaft 707. All sets of stirring rods 708 are located inside the stirring tank 4. The driving mechanism 8 is located on the top of the base 1 and connected to the slide 3.

[0033] Two telescopic support rods 709 are fixedly connected through the slide block 3. The telescopic ends of the telescopic support rods 709 are fixedly connected to the bottom of the top seat 703. The two telescopic support rods 709 are located close to the front and rear sides of the slide block 3, respectively. The two telescopic support rods 709 and the electric cylinder 702 are arranged in an isosceles triangle. Multiple guide rods 710 are movably installed through the mounting base 705. The bottom of the multiple guide rods 710 is fixedly connected to a cover 711. A through groove is opened in the center of the cover 711. 712, the size of the through groove 712 is larger than the size of the rotating shaft 707, the bottom of the cover 711 fits against the top opening of the mixing tank 4; the guide rod 710 is externally fitted with a spring 713, the two ends of the spring 713 are fixedly connected to the mounting base 705 and the cover 711 respectively; the bottom of the cover 711 is fitted with a sealing gasket 714, which is made of rubber material; multiple guide rods 710 are arranged in a ring array, and the top of the guide rod 710 is fixedly connected to a limit block 701.

[0034] In practical implementation, during operation, the raw materials required for cement production can be added into the mixing tank 4 through the feed hopper 5. Then, the reduction motor 706 can be started, driving the rotating shaft 707 and the stirring rods 708 to rotate, thereby mixing the cement raw materials inside the mixing tank 4. Simultaneously, the electric cylinder 702 is activated, causing it to reciprocate within a set range, thereby driving the top seat 703 and the mounting seat 705 to move up and down, which in turn drives the rotating shaft 707 and multiple sets of stirring rods 708 to move up and down within a certain range. Therefore, it can effectively reduce the dead zones in the mixing tank 4, improve the uniformity of mixing, and achieve the desired effect. The purpose of cement production and processing quality is to extend the electric cylinder 702 to its maximum extension distance after cement production and processing is completed. This will cause the top seat 703 to move upward, thereby causing the mounting seat 705, rotating shaft 707, and stirring rod 708 to move upward until the rotating shaft 707 and stirring rod 708 are both moved to the outside of the mixing tank 4. This allows for the cleaning of the rotating shaft 707, stirring rod 708, and the inner wall of the mixing tank 4 by an external high-pressure water gun mechanism. The cleaning effect is good. After the cleaning work is completed, the rotating shaft 707 and stirring rod 708 can be reset, which will not easily affect the next round of cement production and processing.

[0035] Among them, what kind of support rod can improve the overall stability of the top seat 703, making it less prone to shaking, thereby making the stirring rod 708 less prone to shaking;

[0036] During operation, the cover 711 can fit against the top opening of the mixing tank 4, effectively preventing material from splashing out from the top opening of the mixing tank 4. When the mounting base 705 moves up and down, the spring 713 can extend and retract to ensure that the cover 711 remains in contact with the top opening of the mixing tank 4 without obstructing the up and down movement of the mounting base 705. The guide rod 710 can improve the overall stability of the cover 711.

[0037] Among them, the sealing gasket 714 can improve the sealing performance at the connection between the cover 711 and the top opening of the mixing tank 4, effectively preventing material leakage;

[0038] The design of multiple guide rods 710 arranged in a ring array can uniformly improve the stability of the cover 711, and the fixed connection of the top end of the guide rod 710 with the limit block 701 is to prevent the guide rod 710 from separating from the mounting base 705. Specific Implementation Example 2:

[0040] Reference Figure 3 and Figure 6 In a preferred embodiment, the drive mechanism 8 includes a cylinder 801, which is fixedly mounted on the top of the base 1 by a mounting member. The telescopic end of the cylinder 801 is fixedly connected to a transmission plate 802, and the top of the transmission plate 802 is fixedly connected to the bottom of the slide block 3.

[0041] In the specific implementation process, when carrying out cleaning work, the electric cylinder 702 can be started first to move the rotating shaft 707 and the stirring rod 708 to the outside of the mixing tank 4. Then, the pneumatic cylinder 801 can be started to extend it, which, in conjunction with the two sliding grooves 2, moves the sliding seat 3, thereby moving the rotating shaft 707 and the stirring rod 708 laterally until the rotating shaft 707 and the stirring rod 708 are moved to the top away from the mixing tank 4. At this time, the rotating shaft 707, the stirring rod 708, and the inside of the mixing tank 4 can be cleaned. Since the rotating shaft 707 and the stirring rod 708 are far away from the top of the mixing tank 4, it is convenient for the staff to clean the inner wall of the mixing tank 4. It can also effectively prevent the rotating shaft 707 and the stirring shaft from being accidentally started and rotated, which could injure the staff. This reduces the safety hazards when cleaning the inner wall of the mixing tank 4, and thus effectively improves the convenience and safety of the cleaning work.

[0042] Working Principle: During operation, the raw materials required for cement production can be added into the mixing tank 4 through the feed hopper 5. Then, the reduction motor 706 is started, driving the rotating shaft 707 and the stirring rods 708 to rotate, thereby mixing the cement raw materials inside the mixing tank 4. Simultaneously, the electric cylinder 702 is activated, causing it to reciprocate within a set range, which in turn drives the top seat 703 and the mounting seat 705 to move up and down, which in turn drives the rotating shaft 707 and multiple sets of stirring rods 708 to move up and down within a certain range. Therefore, it can effectively reduce the dead zones in the mixing tank 4, improve the uniformity of mixing, and achieve the goal of improving cement production efficiency. To improve the quality of cement production and processing, after cement production and processing are completed, the electric cylinder 702 can be activated to extend to its maximum extension distance, driving the top seat 703 to move upward, thereby driving the mounting base 705, the rotating shaft 707, and the stirring rod 708 to move upward until the rotating shaft 707 and the stirring rod 708 are both moved to the outside of the mixing tank 4. This allows for the cleaning of the rotating shaft 707, the stirring rod 708, and the inner wall of the mixing tank 4 by an external high-pressure water gun mechanism. The cleaning effect is good. After the cleaning work is completed, the rotating shaft 707 and the stirring rod 708 can be reset, which will not easily affect the next round of cement production and processing.

[0043] Furthermore, during cleaning, the electric cylinder 702 can be activated first to move the rotating shaft 707 and the stirring rod 708 upwards to the outside of the mixing tank 4. Then, the pneumatic cylinder 801 can be activated to extend it, which, in conjunction with the two sliding grooves 2, moves the sliding seat 3, thereby causing the rotating shaft 707 and the stirring rod 708 to move laterally until they are above the mixing tank 4. At this point, the rotating shaft 707, the stirring rod 708, and the interior of the mixing tank 4 can be cleaned. Since the rotating shaft 707 and the stirring rod 708 are above the mixing tank 4, it is easier for workers to clean the inner wall of the mixing tank 4. This also effectively prevents the rotating shaft 707 and the stirring shaft from being accidentally started and rotated, which could injure workers. This reduces the safety hazards when cleaning the inner wall of the mixing tank 4, thereby effectively improving the convenience and safety of the cleaning work.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
