Description

Technical Field

[0001] The utility model relates to the technical field of grinding aid metering, and more specifically, to a grinding aid metering device. Background Art

[0002] In the existing technology, the liquid grinding aid metering device is a key equipment in the cement production process. As an auxiliary material, cement grinding aid can significantly improve the performance of cement, including improving grinding efficiency, improving cement quality and reducing energy consumption. With the development of the cement industry, it is particularly important to accurately control the amount of grinding aid added, because it directly affects the quality and production cost of cement products.

[0003] However, the existing grinding aid metering devices have some technical limitations in terms of precise proportioning. First, the existing technology often cannot provide intuitive and accurate observation of the grinding aid dosage. The inaccuracy of this observation may lead to excessive or insufficient addition of grinding aid, thereby affecting the quality of cement or increasing production costs.

[0004] Secondly, existing grinding aid storage tanks are usually placed directly on the ground. This arrangement has some problems. Since the ground may be uneven, the liquid level in the storage tank may be tilted, affecting the accuracy of the liquid level meter reading. This inaccuracy may cause deviations in the amount of grinding aid added, thereby affecting the cement production process and product quality.

[0005] In addition, in the prior art, the delivery of liquid grinding aids usually relies on a pipeline system. However, the existing internal structure of the pipeline is relatively simple and lacks flexibility, and the delivery speed cannot be adjusted according to actual needs. This limitation may lead to untimely or excessive delivery of grinding aids, affecting efficiency and product quality. Utility Model Content

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the utility model provides a grinding aid metering device, which has the following beneficial effects:

[0019] 1. The design of the metering device realizes accurate observation of the liquid level of the grinding aid through the coordinated action of the connecting pipe, the metering tube and other components. The connecting pipe connects the storage tank and the metering tube, so that the grinding aid can flow smoothly into the metering tube. A ruler and a scale bar are provided on one side of the metering tube. The liquid level of the grinding aid can be observed intuitively through the moving position of the float and the scale line on the ruler. This design enables the operator to accurately understand the amount of grinding aid added, thereby improving the quality of the final product.

[0020] 2. The design of the leveling device achieves smooth adjustment of the storage tank through the coordinated action of the support block, the fixing ear, the adjusting rod and the connecting frame. The adjusting rod and the connecting frame are movably connected through threads. By turning the adjusting rod, the support block can be driven up or down to adjust the balance state of the storage tank. This design enables the storage tank to adapt to the uneven ground, maintain the stability of the liquid level, and ensure the accuracy of the grinding aid metering.

[0021] 3. The design of the regulating device realizes the flexible adjustment of the liquid delivery speed in the pipeline through the coordinated action of the baffle block, matching block, screw, rotating tube, internal gear and external gear. Driven by the motor, the driving wheel drives the driven wheel to rotate, and then drives the internal gear to rotate. Through the meshing action of the gears, the screw sleeve rotates, thereby driving the screw to rise. The rise of the screw pushes the baffle block to move, and the baffle block drives the sliding block to slide along the inclined sliding groove, thereby changing the cross-sectional area of ​​the corresponding position in the connecting pipe and limiting the flow speed of the liquid in the pipe. This design enables the operator to adjust the delivery speed of the grinding aid according to actual needs, thereby improving the flexibility and accuracy of the equipment.

The inner gear 12 is fixedly connected to the inner side of the rotating tube 10, and the outer gear 13 is fixedly connected to the outer side of the screw sleeve 14. The driving wheel 15 is installed at the output end of the motor 16, and the driven wheel 9 is fixedly connected to the outer side of the rotating tube 10, and the driving wheel 15 is meshed with the driven wheel 9. A leveling device is provided at the bottom end of the storage tank 1, and the leveling device includes a support block 18, an adjusting rod 19 and a connecting frame 20. The connecting frame 20 is arranged at the bottom end of the storage tank 1, and the adjusting rod 19 and the connecting frame 20 are movably connected through threads, and the support block 18 is fixedly provided at the bottom end of the adjusting rod 19.

[0032] A fixing ear 21 is provided at the top of the screw rod 6 , and the fixing ear 21 is fixedly connected to the top of the screw rod 6 .

[0033] A limiting plate 22 is provided in the fixing tube 11 , and the screw sleeve 14 is rotatably mounted on the limiting plate 22 .

[0034] A sliding block 23 is provided on one side of the baffle block 3 , a sliding groove 24 is provided on the inner side of the connecting pipe 8 , and the sliding block 23 is slidably arranged in the sliding groove 24 .

[0035] The sliding groove 24 is designed as an inclined structure.

[0036] In this embodiment, when it is necessary to adjust the conveying speed in the pipeline accordingly, the motor 16 is turned on, and the motor 16 drives the driven wheel 9 to rotate through the driving wheel 15 connected to the output end, and then the driven wheel 9 drives the internal gear 12 to rotate through the rotating tube 10, and then the internal gear 12 drives the external gear 13 meshing therewith to rotate, thereby driving the screw sleeve 14 to rotate. Since the screw sleeve 14 and the screw rod 6 are movably connected through threads, and the matching groove 5 and the matching block 4 form a limit to prevent the screw rod 6 from rotating, then the screw rod 6 will rise along the screw sleeve 14, and then the screw 6 will push the baffle block 3 to move, and then the baffle block 3 will drive the sliding block 23 to slide along the sliding groove 24. Due to the special inclined structural design of the sliding groove 24 , the baffle block 3 will gather inward while moving, and the baffle block 3 will slide along the matching groove 5 and the matching block 4, and then the top block 7 will gradually come together, and then the push spring 17 connected to one side of the top block 7 will be compressed, so that the gap between the push springs 17 will change, thereby limiting the speed at which the liquid passes through. At the same time, the movement of the baffle block 3 changes the cross-sectional area of ​​the corresponding position in the connecting pipe 8, thereby further limiting the flow rate of the liquid in the pipe. When it is necessary to level the storage tank 1, the adjusting rod 19 is rotated through the fixing ear 21. Since the adjusting rod 19 and the connecting frame 20 are movably connected through threads, when the adjusting rod 19 is rotated, it will drive the support block 18 to rise or fall. When the equipment is leveled, stop rotating the fixing ear 21 and the adjusting rod 19.

[0037] See also Figure 1 and Figure 3 As an implementation method of a grinding aid metering device, the metering device includes a connecting pipe 25 and a metering pipe 26, one end of the connecting pipe 25 is connected to the storage tank 1, and the other end of the connecting pipe 25 is connected to the metering pipe 26.

[0038] A ruler 27 is provided on one side of the measuring tube 26 , and a scale bar 28 is provided on one side of the ruler 27 .

[0039] A buoy 29 is provided in the metering tube 26 , and the buoy 29 is movably disposed in the metering tube 26 .

[0040] More specifically, after the equipment is leveled, the liquid grinding aid is transported to the storage tank 1, and then the grinding aid entering the storage tank 1 will enter the metering tube 26 through the connecting tube 25, the liquid level will gradually rise, and then the grinding aid entering the metering tube 26 will lift the buoy 29, causing the buoy 29 to move in the transparent tube, and then the liquid level of the grinding aid can be accurately observed by the moving position of the buoy 29 combined with the scale lines on the ruler 27, thereby improving the quality of the final product.

[0041] In summary, when the overall equipment is in use or running: when it is necessary to adjust the conveying speed in the pipeline accordingly, turn on the motor 16, the motor 16 drives the driven wheel 9 to rotate through the driving wheel 15 connected to the output end, and then the driven wheel 9 will drive the internal gear 12 to rotate through the rotating tube 10, and then the internal gear 12 will drive the external gear 13 meshing therewith to rotate, thereby driving the screw sleeve 14 to rotate, because the screw sleeve 14 and the screw rod 6 are movably connected through threads, and the matching groove 5 and the matching block 4 form a limit to prevent the screw rod 6 from rotating, then the screw rod 6 will rise along the screw sleeve 14, and then the screw 6 will push the baffle block 3 to move, and then the baffle block 3 will drive the sliding block 23 to slide along the sliding groove 24, due to the special inclined type of the sliding groove 24 According to the structural design, the baffle block 3 will gather inward while moving, and the baffle block 3 will slide along the matching groove 5 and the matching block 4, and then the top block 7 will gradually come together, and then the push spring 17 connected to one side of the top block 7 will be compressed, so that the gap between the push springs 17 will change, thereby limiting the speed at which the liquid passes through. At the same time, the movement of the baffle block 3 changes the cross-sectional area of ​​the corresponding position in the connecting pipe 8, thereby further limiting the flow speed of the liquid in the pipe. When it is necessary to level the storage tank 1, the adjusting rod 19 is rotated through the fixing ear 21. Since the adjusting rod 19 and the connecting frame 20 are movably connected through threads, when the adjusting rod 19 is rotated, it will drive the support block 18 to rise or fall. When the equipment is leveled, stop rotating the fixing ear 21 and the adjusting rod 19.

[0042] After the equipment is leveled, the liquid grinding aid is transported to the storage tank 1, and then the grinding aid entering the storage tank 1 will enter the metering tube 26 through the connecting pipe 25. The liquid level gradually rises, and then the grinding aid entering the metering tube 26 will lift the buoy 29, causing the buoy 29 to move in the transparent tube. Then, the liquid level of the grinding aid can be accurately observed through the moving position of the buoy 29 combined with the scale lines on the ruler 27, thereby improving the quality of the final product.
