Description

Technical Field

[0001] This utility model relates to the field of humic acid production, and in particular to a metering device for humic acid production. Background Technology

[0002] Humic acid has a wide range of applications in many fields. In agriculture, it serves as a high-quality organic fertilizer additive, improving soil structure, enhancing soil fertility, and promoting crop growth. Industrially, it is frequently used as a chemical raw material and water treatment agent. In the production process of humic acid, the metering step is crucial. Accurate metering not only affects the stability of product quality but also influences the effectiveness of subsequent applications. Therefore, appropriate metering equipment is essential for achieving accurate metering of humic acid and ensuring its optimal condition during production.

[0003] In existing humic acid production, metering operations are usually carried out using ordinary metering tanks. The metering tank is generally equipped with a feed pipe to receive the humic acid material to be metered, and a discharge pipe at the bottom is responsible for transporting the metered material to the subsequent process.

[0004] In the existing technology, traditional stirring devices can only achieve rotational stirring in one direction. For humic acid, a liquid with a certain viscosity, the stirring effect is limited, making it difficult to mix the liquid thoroughly and evenly. This may lead to differences in the quality of different batches of humic acid during subsequent metering and discharge, affecting the stability of product quality and its performance in various application scenarios. Therefore, a metering device for humic acid production is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a metering device for humic acid production, comprising a metering tank, a feed pipe at the top of the metering tank, a discharge pipe at the bottom of the metering tank, a metering tube on the outer wall of the metering tank, a drive motor fixedly connected to the top of the metering tank, a fixed shaft fixedly connected to the output end of the drive motor, a sleeve fixedly connected to the inner wall of the right end of the metering tank, a lifting mechanism on the inner wall of the sleeve, a rectangular block fixedly connected to the outer wall of the fixed shaft, a stirring shaft slidably connected to the outer walls of both the fixed shaft and the rectangular block, multiple sets of stirring shafts being fixedly connected to each other via connecting plates, a pressing plate fixedly connected to the outer wall of the fixed shaft, and a cleaning mechanism on the outer wall of the metering tank; The lifting mechanism includes a movable tube that passes through and is slidably connected to the inner wall of the sleeve. The left end of the movable tube is hinged to a connecting ring via a hinge rod.

[0007] As a further description of the above technical solution: The cleaning mechanism includes a servo motor, which is fixedly connected to the outer wall of the metering tank via a bracket.

A support plate is fixedly connected to the outer wall of the metering tank.

[0008] As a further description of the above technical solution: The reciprocating lead screw is rotatably connected to the inner wall of the support plate.

[0009] As a further description of the above technical solution: The guide rod is fixedly connected to the inner wall of the support plate.

Detailed Implementation

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3This utility model provides an embodiment of a metering device for humic acid production, comprising a metering tank 1, an inlet pipe 2 at the top of the metering tank 1 allowing liquid humic acid to enter the metering tank 1, and an outlet pipe 3 at the bottom of the metering tank 1 to deliver the humic acid to the reaction vessel of the next production process in a set quantity. A metering tube 4 with clear graduation markings is provided on the outer wall of the metering tank 1, allowing for a direct observation of the approximate height of the liquid within the metering tank 1 by observing the liquid level. A drive motor 5 is fixedly connected to the top of the metering tank 1, and a fixed shaft 6 is fixedly connected to the output end of the drive motor 5. The fixed shaft 6 primarily connects to the entire stirring shaft 12. A sleeve 7 is fixedly connected to the inner wall of the right end of the metering tank 1, providing a sliding point for a moving tube 8, allowing the moving tube 8 to move laterally along the sleeve 7. The inner wall of the sleeve 7 is equipped with a lifting mechanism. A rectangular block 11 is fixedly connected to the outer wall of the fixed shaft 6. The rectangular block 11 allows the fixed shaft 6 to rotate with the stirring shaft 12, and also allows the stirring shaft 12 to move up and down. The outer walls of the fixed shaft 6 and the rectangular block 11 are slidably connected to the stirring shaft 12. The stirring shaft 12 has stirring blades, which can stir the humic acid liquid to prevent it from stratifying. There are multiple sets of stirring shafts 12, which are fixedly connected to each other by connecting plates 13. The connecting plates 13 connect multiple stirring shafts 12 together to ensure that multiple connecting plates 13 rotate or move up and down synchronously. A squeezing plate 14 is fixedly connected to the outer wall of the fixed shaft 6. The right end of the squeezing plate 14 is inclined, which can squeeze the moving tube 8 to make it move. The outer wall of the metering tank 1 is equipped with a cleaning mechanism.

[0020] The lifting mechanism includes a movable tube 8, which is slidably connected to the inner wall of the sleeve 7. The sleeve 7 has a corresponding slot for the movable tube 8, which allows the movable tube 8 to move along the inner wall of the sleeve 7. The sleeve 7 is located above the inner wall of the metering tank 1, and the liquid will not completely enter the sleeve 7. The opening of the sleeve 7 is vertically connected. The left end of the movable tube 8 is hinged to a connecting ring 10 via a hinge rod 9.

[0021] Reference Figure 1 and Figure 4The cleaning mechanism includes a servo motor 15, which is fixedly connected to the outer wall of the metering tank 1 via a bracket. A reciprocating lead screw 16 is fixedly connected to the output end of the servo motor 15. The reciprocating lead screw 16 is a transmission component capable of converting rotary motion into linear reciprocating motion, or vice versa. A slider 19 is provided on the outer wall of the reciprocating lead screw 16. A groove matching the reciprocating lead screw 16 is formed in the middle of the slider 19. A guide rod 17 is slidably connected through the inner wall of the slider 19, allowing the slider 19 to move vertically. The slider 19 moves in a direction that does not deviate from its trajectory. A cleaning ring 20 is fixedly connected to the left end of the slider 19. A support plate 18 is fixedly connected to the outer wall of the metering tank 1. The support plate 18 mainly supports and connects the reciprocating screw 16 and the guide rod 17. The reciprocating screw 16 is rotatably connected to the inner wall of the support plate 18, and the guide rod 17 is fixedly connected to the inner wall of the support plate 18. The inner wall of the cleaning ring 20 is in contact with the outer wall of the metering tube 4. The cleaning ring 20 is made of rubber and can absorb cleaning agent, helping the cleaning ring 20 to clean the surface of the metering tube 4.

[0022] Reference Figures 1-3 The left end of the moving tube 8 is hinged to one end of the hinge rod 9. Since the length of the hinge rod 9 is fixed, when the moving tube 8 moves to the right, it will cause the moving tube 8 to move to the right along with one end of the hinge rod 9. Then the other end of the hinge rod 9 will move upward along with the connecting ring 10. Conversely, when the moving tube 8 moves to the left with one end of the hinge rod 9, the other end of the hinge rod 9 will move downward along with the connecting ring 10. The other end of the hinge rod 9 is hinged to the outer wall of the connecting ring 10. The connecting ring 10 is rotatably connected to the outer wall of the stirring shaft 12. The right end of the extrusion plate 14 is in contact with the upper end of the moving tube 8. The fixed shaft 6 is rotatably connected to the inner wall of the metering tank 1.

[0023] Working principle: When it is necessary to stir the stratified humic acid liquid in metering tank 1, simply start the drive motor 5. The output of the drive motor 5 drives the fixed shaft 6 to rotate, causing the stirring shaft 12 to rotate along with the fixed shaft 6. The stirring blades on the stirring shaft 12 stir the humic acid liquid in metering tank 1, preventing stratification and ensuring the uniformity of the liquid. Furthermore, multiple stirring shafts 12 are fixedly connected by connecting plates 13, ensuring that multiple stirring shafts 12 can rotate and stir synchronously. When the fixed shaft 6 rotates, its outer wall is fixed... The extrusion plate 14 also rotates. The right end of the extrusion plate 14 is inclined. During the clockwise rotation, it will contact the upper end of the moving tube 8 and generate an extrusion effect. Since the sleeve 7 provides a sliding point for the moving tube 8, the moving tube 8 can move laterally along the sleeve 7. When the moving tube 8 moves, it will eventually drive the stirring shaft 12 to move upward. Conversely, when the moving tube 8 returns to the left, the stirring shaft 12 will return to the lower position due to its own gravity. In this way, the stirring shaft 12 can move up and down while rotating and stirring, which further enhances the stirring effect on the humic acid liquid and makes the liquid in the tank more fully mixed.

[0024] When cleaning the metering tube 4 is required, simply start the servo motor 15. The output of the servo motor 15 drives the reciprocating screw 16 to rotate. When the reciprocating screw 16 rotates, the slider 19 will move back and forth in a straight line along the reciprocating screw 16. Driven by the slider 19, the cleaning ring 20 moves back and forth in a straight line along the outer wall of the metering tube 4, thereby wiping and cleaning the surface of the metering tube 4, removing dirt and other impurities that may be attached to the outer wall of the metering tube 4, ensuring that the metering tube 4 can display the liquid level height normally and accurately, and maintaining the good operating condition of the entire metering equipment.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
