Description

Technical Field

[0001] This invention relates to the field of liquid proportioning technology, and in particular to a coal gangue silicate activator proportioning and supply device. Background Technology

[0002] The coal gangue silicate activator proportioning and supply equipment is an automated batching and conveying integrated device. Its core function is to accurately measure, mix and stably supply silicate activators according to a preset formula, ensuring that the activator and raw materials such as coal gangue continuously and uniformly enter the subsequent reaction or mixing process in a set ratio.

[0003] In existing technologies, when mixing liquids, the liquid is sprayed into a container through a nozzle. After spraying, liquid drips and drips are likely to occur, which reduces the accuracy of the liquid mixing ratio. This causes the actual amount of liquid added to the container to deviate from the preset ratio, thus affecting the overall uniformity of the mixture and the stability of the product performance. The dripping residue also causes raw material waste and is prone to forming scale and adhesion on the inner walls of equipment and containers, increasing the difficulty of subsequent cleaning and maintenance. Some corrosive or viscous liquids can also corrode and contaminate surrounding equipment components, affecting the cleanliness of the production environment and the service life of the equipment.

[0004] Therefore, it is necessary to design a coal gangue silicate activator formulation and supply equipment to solve the above problems. Summary of the Invention

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1: This example describes a coal gangue silicate activator proportioning and supply device, as disclosed in this example. Figure 1-7The system includes a base 11, which serves as the load-bearing and installation foundation for the entire machine. The base 11 is integrally formed from high-strength cast iron, possessing high structural rigidity and stability. Inside the base 11 is a mixing tank 12, made of corrosion-resistant and acid / alkali-resistant stainless steel. The inner wall is polished to reduce liquid adhesion and residue. During the mixing process, liquids of different components are added to the mixing tank 12 for mixing. The mixing tank 12 can be equipped with a stirring mechanism to improve the mixing uniformity of the multi-component activator raw materials, depending on the application requirements. An annular groove 13 is formed on the top surface of the base 11, extending circumferentially along the upper surface of the base 11. The groove has an arc-shaped cross-section, facilitating the smooth convergence of residual liquid towards the drain port 14. A drain port 14 is formed on the outer surface of the base 11, and the drain port 14 is connected to the annular groove 13. 4. An internal guide slope is provided to reduce liquid flow resistance and prevent liquid from stagnating in the drain channel. A container 15 is provided on the outer surface of the base 11, and the container 15 is positioned directly opposite the drain port 14. The container 15 is made of transparent engineering plastic, which makes it easy for staff to observe the amount of waste liquid collected inside in real time. The container 15 is connected to the base 11 by a detachable structure, which can be a snap-fit ​​connection or a threaded connection. The disassembly and assembly are simple and convenient for staff to clean the liquid in the container 15, preventing the waste liquid from accumulating and causing solidification or odor. An installation ring 2 is provided on the top of the base 11. The installation ring 2 is connected to the base 11 by several connecting rods 21. The installation ring 2 and the base 11 are coaxially arranged to ensure that the running trajectory of each moving part is concentric and to reduce the risk of motion interference. A toothed ring 22 and an annular slide rail 23 are fixedly sleeved on the outer surface of the installation ring 2.

[0021] The mounting ring 2 is equipped with a pushing assembly, which includes a bracket 31. A slide block 311 is fixed on the bracket 31. A wear-resistant sliding bushing is embedded in the inner wall of the slide block 311. The slide block 311 is slidably mounted on the annular slide rail 23. During the movement of the bracket 31, the annular slide rail 23 and the slide block 311 provide radial and axial limits for the bracket 31, allowing the bracket 31 to move smoothly along the outer surface of the mounting ring 2 without shaking or displacement. A cylinder 32 is mounted on the bracket 31, and a push block 3 is fixed to the telescopic end of the cylinder 32. 3. A second motor 41 is installed on the bracket 31. The second motor 41 is a servo geared motor with adjustable speed and precise positioning. It can accurately stop the bracket 31 at any position on the annular slide rail 23. The output shaft of the second motor 41 is fixed with a gear 42, which meshes with the gear ring 22. When the second motor 41 is running, it can drive the gear 42 to rotate. When the gear 42 rotates, it drives the bracket 31 to move circumferentially along the annular slide rail 23 through meshing with the gear ring 22, thereby realizing the free movement of the push component.

[0022] The mounting ring 2 is equipped with several liquid supply components. The number of liquid supply components can be flexibly set according to the composition values ​​of the coal gangue silicate activator. Each liquid supply component includes two fixing plates 51, both of which are fixed to the inner wall of the mounting ring 2. The fixing plates 51 and the mounting ring 2 are fastened together with bolts to ensure a firm and reliable connection structure. Each fixing plate 51 is fixed with a guide rail 52. The guide rail 52 is a precision linear guide rail, which has high guiding accuracy and low running resistance. Each guide rail 52 is slidably equipped with a moving seat 53. A liquid supply seat 54 is fixed between two moving seats 53. The liquid supply seat 54 adopts a sealed cavity structure and has a diversion channel inside. The liquid supply seat 54 is connected to a liquid supply pipe 541 and a gas supply pipe 542. The liquid supply pipe 541 is used to supply liquid to the liquid supply seat 54. A flow control valve can be installed on the outside of the liquid supply pipe 541 to accurately control the liquid supply volume. The gas supply pipe 542 is used to supply gas to the liquid supply seat 54. A pressure regulating valve can be installed in the gas supply pipe to adjust the gas injection pressure. The liquid supply seat 54 is connected to the mounting ring 2 by a tension spring 55. In the initial state, under the elastic force of the tension spring 55, the liquid supply seat 54 is in a position close to the mounting ring 2. When the pushing component is removed, the tension spring 55 can drive the liquid supply seat 54 and the injection component to automatically reset without the need for additional driving components.

[0023] A spray assembly is provided below the liquid supply base 54. The spray assembly includes two side plates 61, which are symmetrically distributed on both sides of the bottom of the liquid supply base 54. The structure is evenly stressed. Both side plates 61 are fixed to the bottom surface of the liquid supply base 54. A rotating shaft 62 is rotatably installed on each side plate 61. A spray pipe 63 is fixed between the two rotating shafts 62. The spray pipe 63 is made of wear-resistant and corrosion-resistant metal tubing. The pipe opening is set with a tapered structure to improve the concentration of liquid spray. The spray pipe 63 is connected to the liquid supply base 54 through a flexible hose. The flexible hose is a telescopic high-pressure hose that can adapt to changes in the position and angle of the spray pipe 63.

[0024] In the initial state, each nozzle 63 is set vertically, and the nozzle openings of several nozzles 63 are all facing the annular groove 13, which facilitates the unified collection and treatment of residual liquid. When mixing liquid, the operator can select different liquid supply seats 54 according to the required liquid composition without the need for manual pipe connection switching, thus improving the automation level of the mixing operation. Specifically, the second motor 41 drives the gear 42 to rotate. Under the cooperation of the gear 42 and the gear ring 22, the second motor 41 drives the bracket 31 to move, so that the bracket 31 drives the cylinder 32 to move along the outer surface of the mounting ring 2 until the cylinder 32 moves to the work position corresponding to a certain liquid supply seat 54. The encoder of the motor can realize the closed-loop control of position and the positioning accuracy is high.

[0025] Until cylinder 32 moves to a position directly opposite one of the liquid supply seats 54, cylinder 32 operates, its telescopic end extends and drives push block 33 to move. As push block 33 moves, it pushes the liquid supply seat 54, causing it to move along guide rail 52. As the liquid supply seat 54 moves, nozzle 63 moves synchronously. The movement is smooth and without shaking until nozzle 63 moves above proportioning tank 12. A reasonable distance is maintained between the nozzle 63 opening and the proportioning tank 12 inlet to prevent liquid splashing. Further, the liquid... The liquid enters the liquid supply seat 54 through the liquid supply pipe 541. The liquid supply pipe can be equipped with a flow meter to realize the liquid metering supply and improve the proportioning accuracy. Then, it enters the nozzle 63 through the hose and is finally sprayed into the interior of the proportioning tank 12 through the nozzle 63. In summary, the device uses different liquid supply seats 54 to provide liquids of different components to the proportioning tank 12. The supply order and supply amount of each component can be preset and adjusted by the electronic control system, so as to realize the automatic and accurate proportioning and mixing of liquids, which can meet the proportioning requirements of large-scale production of coal gangue silicate activator.

[0026] Example 2: Based on Example 1, this example discloses a coal gangue silicate activator proportioning and supply device, such as... Figure 4 and Figure 5 As shown, a mounting rod 34 is fixed to the side of the push block 33. The mounting rod 34 is a rigid rod to ensure the stability of the transmission structure. A mounting bracket 35 is fixed to the end of the mounting rod 34 away from the push block 33. The mounting bracket 35 provides a stable mounting base for the first motor 36. The first motor 36 is mounted on the mounting bracket 35. The first motor 36 is also a servo motor, which can realize forward and reverse rotation and precise angle control. A rotating disk 37 is fixed to the output shaft of the first motor 36. The rotating disk 37 has a small moment of inertia and responds quickly. A pressure rod 38 is fixed to the edge of the rotating disk 37. A crossbar 64 is fixed on one of the rotating shafts 62. A groove 641 is opened at the end of the crossbar 64 away from the corresponding rotating shaft 62. The contour of the groove 641 matches the end of the pressure rod 38 to ensure stable transmission and no slippage after the pressure rod 38 is inserted. The end of the pressure rod 38 is rounded to avoid jamming when it is inserted into the groove 641.

[0027] like Figure 6 As shown, during the process of the cylinder 32 pushing the liquid supply seat 54 to move, when the push block 33 contacts the liquid supply seat 54, the pressure rod 38 on the rotating disk 37 moves to the position directly opposite the groove 641. The component position matching accuracy is high, and no additional calibration and adjustment are required. During the subsequent process of the push block 33 pushing the liquid supply seat 54 to move, the pressure rod 38 is always directly opposite the groove 641, ensuring that the angle adjustment mechanism can be put into operation at any time.

[0028] Therefore, the first motor 36 can control the angle of the nozzle 63 through the pressure rod 38 and the crossbar 64, realizing the active adjustment of the nozzle 63's attitude to adapt to different working conditions. Specifically, when the first motor 36 operates, it drives the rotating disk 37 to rotate. When the rotating disk 37 rotates, it drives the pressure rod 38 to rotate. When the pressure rod 38 rotates, it can engage in the groove 641 and press down the crossbar 64, causing the crossbar 64 to drive the corresponding rotating shaft 62 to rotate, ultimately causing the nozzle 63 to rotate. The transmission process is direct and efficient, thereby achieving the effect of adjusting the angle of the nozzle 63. Figure 7 As shown, during the process of adding liquid to the mixing tank 12, the nozzle 63 can be rotated to an inclined state. The inclination angle can be flexibly adjusted according to the position of the feed inlet so that the nozzle 63 can smoothly inject liquid into the mixing tank 12, reducing liquid splashing and waste. After the liquid injection is completed, the nozzle 63 is adjusted to a state where the nozzle opening is tilted upward. In this state, the liquid remaining in the nozzle 63 flows back to the tail of the nozzle 63 under the action of gravity and will not drip downward, avoiding the situation where residual liquid drips randomly and contaminates the equipment and working environment.

[0029] When the nozzle 63 returns to its initial position, the first motor 36 reverses its rotation until the pressure rod 38 separates from the crossbar 64, releasing the constraint on the crossbar 64. This allows the nozzle 63 to return to a vertical position under its own weight, eliminating the need for an additional reset mechanism. In this state, the nozzle 63's inlet faces the annular groove 13, allowing residual liquid in the nozzle 63 to drip into it. The groove's interior is smooth with no dead corners, ensuring smooth liquid flow. The liquid eventually enters the container 15 through the drain port 14, achieving centralized collection of residual waste liquid. Furthermore, in the liquid jet formation... After the nozzle 63 moves to the top of the annular groove 13, the air source provides high-pressure gas to the liquid supply seat 54 through the air supply pipe 542. The gas pressure can be adjusted according to the cleaning requirements, so that the gas is sprayed out through the nozzle 63. The gas sprayed out by the nozzle 63 can form an airflow flushing effect, carrying out the residual liquid in the nozzle 63. At the same time, it can blow away and clean the viscous liquid attached to the inner wall of the nozzle 63, thus cleaning the nozzle 63, preventing the residual liquid from solidifying and clogging the nozzle 63, ensuring the long-term smooth flow of the nozzle 63, and improving the reliability and service life of the equipment.
