Description
Technical Field
[0001] This utility model relates to a grinding device for zeolite powder. Background Technology
[0002] Zeolite powder is a powdery substance made from natural zeolite through processes such as crushing, grinding, and screening. Its main component is aluminosilicate mineral. Due to its unique crystal structure, zeolite has properties such as adsorption, ion exchange, and catalysis, which enable it to play an important role in many fields. When grinding zeolite powder, additives (including catalysts, buffers, and fillers, etc.) also need to be added.
[0003] Most existing grinding equipment is equipped with only one hopper, where zeolite particles and additives are added together. However, due to the lack of a stirring mechanism in the hopper, the zeolite particles and additives cannot be fully and evenly mixed, and the grinding speed is also relatively slow. In addition, the effective grinding time of existing grinding equipment is short, resulting in poor grinding effect, which leads to large differences in particle size in the ground products and a low qualified rate of the finished product. Further improvements are needed. Utility Model Content

[0019] The main body 2 also includes a feed pipe 25 vertically arranged above the first screw conveyor 26, a first hopper 21 and a second hopper 23 fixed on the movable frame 1 and higher than the grinding box 27, a second screw conveyor 22 arranged between the first hopper 21 and the feed pipe 25, and a third screw conveyor 24 arranged between the second hopper 23 and the second screw conveyor 22.
[0020] The lower opening of the feed pipe 25 is inserted into the upper side of the cylinder of the first screw conveyor 26 and communicates with the inside of the cylinder of the first screw conveyor 26. The upper opening of the feed pipe 25 is communicated with the discharge port of the second screw conveyor 22.

[0021] The discharge port of the third screw conveyor 24 is inserted into one side of the cylinder of the second screw conveyor 22 and communicates with the inside of the cylinder of the second screw conveyor 22. The inlet of the third screw conveyor 24 is inserted into the bottom of the second hopper 23 and communicates with the inside of the second hopper 23.
[0022] The inside of the movable frame 1 is also fixed with a receiving hopper 3, and the bottom opening of the grinding box 27 is sealed to the top opening of the receiving hopper 3.
[0023] A detachable storage compartment 4 is fixed at the bottom opening of the receiving hopper 3. The bottom of the storage compartment 4 is inclined. A discharge pipe 8 is inserted into the lowest side of the bottom of the storage compartment 4. A discharge valve 9 is connected in series on the discharge pipe 8.
[0024] A stirring motor 5 is fixed to the top of the storage hopper 4. A vertically arranged stirring shaft 10 is also inserted into the top of the storage hopper 4. The rotating shaft of the stirring motor 5 is concentrically fixed to the upper end of the stirring shaft 10. The lower end of the stirring shaft 10 extends into the interior of the storage hopper 4 and extends to the top of the root opening of the discharge pipe 8. An impeller 11 is also fixed to the lower end of the stirring shaft 10.
[0025] The top of the mobile frame 1 is also fixed with a bottom plate 13 that is horizontally closed at the top opening of the receiving hopper 3. The top of the bottom plate 13 is also fixed with a separation cover 6. The outer wall of the separation cover 6 is also fixed with a fan 7. The air inlet of the fan 7 is inserted into the top side of the separation cover 6 and communicates with the interior of the separation cover 6.
[0026] The separation hood 6 is also equipped with multiple conical filter cylinders 12. The lower opening of each conical filter cylinder 12 is inserted and fixed in the bottom plate 13 and is connected to the inside of the receiving hopper 3.
[0027] The top openings of the first hopper 21 and the second hopper 23 are respectively fixed with a detachable first hopper cover 216 and a second hopper cover 217.
[0028] Working principle: Open the first hopper cover 216 and pour the zeolite particles into the first hopper 21. Then open the second hopper cover 217 and pour the additives (such as catalysts, buffers, or fillers) into the second hopper 23. Then start the second screw conveyor 22 and the third screw conveyor 24 in the main body 2 at the same time. The second screw conveyor 22 will transport the zeolite particles to the feed pipe 25 at a certain speed. However, before the zeolite particles enter the feed pipe 25, the third screw conveyor 24 will transport the additives into the cylinder of the second screw conveyor 22, and then mix them with the zeolite particles. After mixing, they will enter the feed pipe 25 together.
[0029] Next, the first screw conveyor 26 is started. The first screw conveyor 26 will transport the zeolite particle mixture in the feed pipe 25 to the grinding box 27 in the grinding head at a certain speed. At the same time, the grinding motor 212 in the main body 2 is started to rotate its rotating shaft. Then, the traction shaft 211 is driven to rotate by the driving pulley 213, the driven pulley 214 and the belt 215. Thus, the cover 28 drives the through cover 29 and each annular grinding roller unit to rotate synchronously. The zeolite particle mixture fed into the grinding box 27 will first enter the innermost annular grinding roller unit. Under the action of centrifugal force, it will continuously collide and grind inside the innermost annular grinding roller unit. Only the powdered zeolite mixture will pass through each annular grinding roller unit from the inside to the outside and fall to the bottom of the grinding box 27.
[0030] Subsequently, the powdered zeolite mixture falls into the receiving hopper 3. At this time, the blower 7 is started to create a negative pressure inside the separation hood 6, which in turn creates a negative pressure inside the receiving hopper 3 through each conical filter cylinder 12, thereby accelerating the falling speed of the powdered zeolite mixture into the receiving hopper 3. The negative pressure causes the powdered zeolite mixture floating in the receiving hopper 3 to enter each conical filter cylinder 12 with the air. The air passes through the filter holes of each conical filter cylinder 12 into the separation hood 6 and is finally discharged outward by the blower 7. The powdered zeolite mixture remains inside each conical filter cylinder 12. When the blower is turned off, the powdered zeolite mixture automatically falls into the receiving hopper 3.
[0031] The powdered zeolite mixture in the receiving hopper 3 will fall further into the storage chamber 4 and accumulate at the bottom of the storage chamber 4. Since the bottom of the storage chamber 4 is inclined, the accumulated powdered zeolite mixture will move towards the discharge pipe 8.
[0032] After the discharge valve 9 is opened, the powdered zeolite mixture will be discharged out through the discharge pipe 8. During this process, the stirring motor 5 needs to be started to make its rotating shaft rotate, which in turn drives the impeller 11 to rotate at the bottom of the storage chamber 4, thereby continuously stirring the powdered zeolite mixture located above the root opening of the discharge pipe 8, which can effectively prevent the root opening of the discharge pipe 8 from becoming blocked.
[0033] This invention separates zeolite particles and additives into the first hopper 21 and the second hopper 23, and uses a third screw conveyor 24 to uniformly mix the additives into the second screw conveyor 22 for moving the zeolite particles, thereby ensuring that the zeolite particles and additives are fully and evenly mixed. At the same time, the blower 7 and multiple conical filter cylinders 12 located in the separation hood 6 create negative pressure in the receiving hopper 3 to accelerate the discharge of the powdered zeolite mixture in the grinding box 27, thereby speeding up the grinding process. In addition, this invention can always confine zeolite particles that do not meet the particle size standard inside the grinding head, thereby significantly extending the effective grinding time of the zeolite particles and effectively improving the grinding effect, thus eliminating particle size differences in the ground products and improving the grinding qualification rate of the finished product.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
