Description

Technical Field

[0001] This utility model belongs to the field of anti-collapse agents, and in particular relates to a grinding device for the production of anti-collapse agents. Background Technology

[0002] Anti-collapse agents are chemical agents primarily used to prevent collapse, stratification, and sedimentation of materials such as drilling fluids and cement slurries under high temperature, high pressure, or during transportation. Grinding refines the particles of the anti-collapse agent, improving its dispersibility in drilling fluids or cement slurries, allowing it to be more evenly distributed in the material and achieving a better anti-collapse effect. Grinding also improves its solubility, making it easier to dissolve in the material and exert its effect. However, current grinding equipment for anti-collapse agents requires sieving after grinding. Materials that do not meet the specifications after sieving need to be manually added back to the grinding equipment for further grinding, which is labor-intensive, cumbersome, and inefficient.

[0021] To better understand the purpose, structure, and function of this utility model, the following detailed description of a grinding device for producing an anti-collapse agent is provided in conjunction with the accompanying drawings.

[0022] like Figures 1 to 4 As shown, this utility model discloses a grinding device for producing an anti-collapse agent, including a grinding tank, a support 2 for supporting the grinding tank, a grinding component 5 disposed in the grinding tank for grinding materials, and a screen 6 disposed below the grinding component 5 inside the tank body 1. In use, materials can be added to the grinding tank, and then the grinding component 5 is started to grind the materials. The ground materials are then screened through the screen 6. The operation is simple and convenient.

[0023] The grinding tank includes a tank body 1, a feed channel 3 connected to the top surface of the tank body 1, and a discharge channel 4 connected to the top surface of the tank body 1. The support 2 includes a support ring 21 on the circumferential wall of the tank body 1 and multiple support legs 22 distributed on the bottom surface of the support ring 21. The grinding assembly 5 for grinding materials includes a material carrier cylinder 52 inside the tank body 1, which is a hollow conical shape, wider at the top and narrower at the bottom. A transmission cylinder 53 is rotatably mounted on the top surface of the tank body 1, coaxially mounted with the tank body 1, and its bottom end extends into the tank body 1. A conical grinding table 51 is also provided on the bottom surface of the transmission cylinder 53, which cooperates with the material carrier cylinder 52, and multiple protrusions 56 are distributed on both the outer wall of the grinding table 51 and the inner wall of the material carrier cylinder 52. Simultaneously, a first motor 54 connected to an external power source is also located on the top surface of the tank body 1, and the first motor 54 is connected to the transmission cylinder 53 via a transmission part 55. Material enters tank 1 through feed channel 3, and the material entering tank 1 flows into the gap between grinding table 51 and material carrier cylinder 52. The first motor 54 is started, and it drives grinding table 51 to rotate via transmission cylinder 53. Under the action of material carrier cylinder 52, the material between material carrier cylinder 52 and grinding table 51 is ground. It should be noted that... Figure 3As shown, the gap between the material carrier cylinder 52 and the grinding table 51 is gradually larger at the top and smaller at the bottom. This makes it easier for the material entering the tank 1 to enter the gap between the material carrier cylinder 52 and the grinding table 51, and also makes it easier to grind the material between the material carrier cylinder 52 and the grinding table 51 little by little. The ground material can then fall directly onto the screen 6 for screening.

[0024] like Figure 1 As shown, the transmission part 55 connecting the first motor 54 and the transmission cylinder 53 includes a first gear 551 disposed on the top surface of the transmission cylinder 53 and a second gear 552 disposed on the output end of the first motor 54. The first gear 551 meshes with the second gear 552. When the first motor 54 drives the second gear 552 to rotate, the second gear 552 also drives the meshed first gear 551 to rotate, thereby causing the transmission cylinder 53 connected to the first gear 551 to rotate.

[0025] To prevent the accumulation of large particles that do not meet the screen mesh specifications on the screen 6, a material recovery component 7 is installed inside the tank 1. This component can re-transport large particles from the screen 6 to the grinding component 5 for further grinding. This not only reduces the accumulation of large particles on the screen 6 but also saves time on manual cleaning of the screen 6 and the labor required to transfer the large particles to the grinding component 5 for re-grinding, thus saving time and improving work efficiency. Specifically, the material recovery component 7 includes a conveying channel 71 installed inside the tank 1 via a mounting plate 74, which passes through the screen 6. A second motor 73, connected to an external power source, is located on the bottom of the tank 1. This motor rotates a spiral conveying shovel 72 located within the conveying channel 71, and the connecting shaft of the spiral conveying shovel 72 passes through the top of the tank 1 and is connected to the second motor 73. Figure 2 As shown, the conveying channel 71 passes through the grinding table 51 and is rotatably mounted thereto. To facilitate the discharge of material from the conveying channel 71, multiple first openings 8 are provided on the bottom surface of the transmission cylinder 53. Similarly, to facilitate the entry of large particles from the screen 6 into the conveying channel 71, second openings 10 are provided on the conveying channel 71 corresponding to the position of the screen 6. When the second motor 73 rotates, it drives the spiral conveying shovel 72 to rotate via the connecting shaft. Material that is not screened off the screen 6 enters the conveying channel 71 through the second openings 10 and moves upward under the action of the spiral conveying shovel 72. It is then discharged through the first openings 8 of the transmission cylinder 53. The material discharged through the first openings 8 re-enters the gap between the loading cylinder 52 and the grinding table 51 for grinding, further improving the practicality of the device. Figure 2As shown, the grinding table 51 has a flat-topped cone 9 on its top surface, which is smaller at the top and larger at the bottom. The conveying channel 71 passes through the flat-topped cone 9 and is rotatably connected to it, and the transmission cylinder 53 is connected to the flat-topped cone 9. The material discharged from the first opening 8 falls onto the flat-topped cone 9, and then falls down the inclined surface of the flat-topped cone 9 into the gap between the material carrier cylinder 52 and the grinding table 51. In order to facilitate the better entry of large particles on the screen 6 into the conveying channel 71, the center of the screen 6 is set to be concave, and the conveying channel 71 is located at the center of the screen 6 and is coaxial with it.

[0026] Preferably, multiple sets of vibrating components are distributed on the lower circumferential wall of the conveying channel 71, and multiple swing arms 11 are distributed on the connecting shaft of the spiral conveying shovel 72, with the swing arms 11 cooperating with the vibrating components. The swing arms 11 drive the vibrating components to work, which in turn causes the screen 6 to vibrate, thereby accelerating the screening efficiency of the screen 6 for materials. Specifically, the vibrating components include a support arm 12 disposed on the conveying channel 71, and the support arm 12 is disposed on the portion of the conveying channel 71 located below the screen 6. Furthermore, a top rod 13 is vertically slidably disposed on the support arm 12, with a limiting plate 14 on the top surface and a contact plate 16 on the bottom surface. A spring 15 is sleeved on the top rod 13 between the limiting plate 14 and the support arm 12, and the swing arms 11 disposed on the connecting shaft of the spiral conveying shovel 72 cooperate with the contact plate 16. When the second motor 73 drives the connecting shaft to rotate, the swing rod 11 set on the connecting shaft will also rotate. When the swing rod 11 rotates, it will contact the contact plate 16 and push the contact plate 16 downward as the swing rod 11 rotates. When the contact plate 16 moves downward, it will drive the top rod 13 connected to it to move downward. The limiting plate 14 set on the top rod 13 will also move downward, and the limiting plate 14 will also compress its corresponding spring 15. When the swing rod 11 passes over the contact plate 16 it is pressing down on, the spring 15 will drive the top rod 13 to move upward through the limiting plate 14, and the contact plate 16 set at the bottom of the top rod 13 will also move upward. When the top rod 13 moves upward, the top rod 13 will impact the screen 6, causing the screen 6 to vibrate, thereby improving the screening efficiency of the screen 6 for materials.

[0027] To facilitate the discharge of material from tank 1, the inner bottom surface of tank 1 is designed as a cone shape, wider at the top and narrower at the bottom. Simultaneously, a scraper 17 is provided on the connecting shaft of the spiral conveyor shovel 72, which mates with the inner bottom surface of tank 1. When the connecting shaft rotates, the scraper 17 on the connecting shaft also rotates, displacing the material on the inner bottom surface of tank 1. When the material is displaced to the discharge channel 4, it enters the discharge channel 4 and is discharged.

[0028] Instructions for use: Start the grinding assembly 5 and the second motor 73. Then, add the material into the tank 1 through the feed channel 3. The material entering the tank 1 will be ground by the grinding assembly 5, and the ground material will fall onto the screen 6 for screening. When the second motor is working, it will drive the swing arm 11 on the connecting shaft to rotate. When the swing arm 11 rotates, it will drive the vibration assembly to work. When the vibration assembly works, it will drive the screen 6 to vibrate, which will make the screen 6 screen the material faster. Large particles falling on the screen 6 will be transported back to the grinding assembly 5 for grinding again through the material recovery assembly 7.
