Description

Technical Field

[0001] This utility model relates to the field of ultrafine pulverizer technology, and in particular to an ultrafine pulverizer that is easy to feed materials. Background Technology

[0002] An ultrafine pulverizer is a device used to pulverize materials to the micron or even nanometer level. It mainly uses high-speed airflow to cause materials to collide and pulverize each other. It is suitable for heat-sensitive materials and is widely used in chemical, pharmaceutical, food and metallurgical fields.

[0003] The ultrafine pulverizer mainly includes a feeding system, a pulverizing chamber, a grading system, and a discharging system. When materials need to be pulverized, the materials are poured into the feeding system in batches. The feeding system allows the materials to enter the pulverizing chamber evenly. After entering the pulverizing chamber, the materials are pulverized by the rotor or hammers. The pulverized materials are screened layer by layer by the grading system. Materials that meet the pulverization requirements are discharged through the discharge pipe.

[0004] However, when the material has excessive moisture or high viscosity, the friction between the material and the inner wall of the feed hopper increases, which can easily cause the material to stick to the wall or even block the feed hopper, affecting the continuous use of the ultrafine pulverizer and reducing its working efficiency. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides an ultrafine pulverizer that facilitates material feeding, aiming to improve the problems in the prior art.

[0027] 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.

[0028] Reference Figure 1-4 One embodiment of this utility model provides: an ultrafine pulverizer for easy material feeding, comprising:

[0029] The ultrafine pulverizer body 1 has a feed pipe 5 fixedly installed on one side for feeding. The outer wall of the ultrafine pulverizer body 1 has an installation hole that communicates with its own inner cavity. One end of the feed pipe 5 is fixedly connected to the inner wall of the installation hole. After the material is poured into the inner cavity of the feed pipe 5, the material enters the inner cavity of the ultrafine pulverizer body 1 along the feed pipe 5 under the action of gravity. The material can be quickly pulverized by the pulverizing equipment inside the ultrafine pulverizer body 1 (this is existing technology and will not be described in detail here).

[0030] The scraper ring 6 is slidably installed in the inner cavity of the feed pipe 5, with its outer wall and the inner wall of the feed pipe 5 in close contact. A connecting block is fixedly installed on the inner wall of the scraper ring 6, and a sliding rod 2 is fixedly installed on the top of the connecting block. A hydraulic cylinder 3 is fixedly installed on the outer wall of the feed pipe 5, and the power output end of the hydraulic cylinder 3 is fixedly connected to the top of the sliding rod 2. After materials with excessive moisture or high viscosity are poured into the inner cavity of the feed pipe 5, the hydraulic cylinder 3 is activated. At this time, the sliding rod 2 moves up and down along its own axis under the action of the hydraulic cylinder 3, thereby causing the scraper ring 6 to move up and down. When the scraper ring 6 moves up and down, it can push the attached... The material with excessive moisture or high viscosity attached to the inner wall of the feed pipe 5 is detached from the inner wall of the feed pipe 5. After detachment, the material falls into the inner cavity of the ultrafine pulverizer body 1 under the action of gravity, which increases the feeding space of the feed pipe 5 and provides a feeding channel for the material. At the same time, the scraper ring 6 can also clear the material in the inner cavity of the feed pipe 5 when it moves up and down, preventing blockage. This improves the smoothness and continuity of feeding materials with excessive moisture or high viscosity, as well as the working efficiency of the ultrafine pulverizer body 1.

[0031] Multiple scraper rings 6 are slidably installed in the inner cavity of the feed pipe 5 along the vertical direction. With the limited vertical movement of the power output end of the hydraulic cylinder 3, the scraper rings 6 can increase the scraping area of ​​the material adhering to the inner wall of the feed pipe 5 and increase the scraping rate of the material adhering to the inner wall of the feed pipe 5.

[0032] The inclined arrangement of the two ends of the multiple scraper rings 6 reduces the contact area between the outer wall of the scraper ring 6 and the inner wall of the feed pipe 5, reduces the resistance when the scraper ring 6 moves up and down, and improves the smoothness of the scraper ring 6's up and down movement.

[0033] A feed rod 7 is rotatably installed vertically inside the feed pipe 5. The top of the feed rod 7 extends directly above the feed pipe 5. A drive motor is fixedly installed on the outer wall of the feed pipe 5. Tensioning wheels are fixedly installed on the power output end of the drive motor and the top of the feed rod 7. The two tensioning wheels are rotatably connected by a tension belt. After the drive motor is started, the two tensioning wheels can rotate synchronously under the action of the tension belt, thus providing a power source for the rotation of the feed rod 7.

[0034] A feeding plate is fixedly installed on the outer wall of the feeding rod 7. The feeding plate is designed with a spiral structure. When the feeding rod 7 rotates along its own axis, the feeding plate rotates simultaneously with the feeding rod 7. The rotating feeding plate can continuously provide downward thrust to the material in the inner cavity of the feeding pipe 5, providing continuous power for the material to fall, preventing the material from being blocked in the inner cavity of the feeding pipe 5, and improving the feeding rate.

[0035] A drive bearing 9 is fixedly installed on the outer wall of the feeding rod 7. Multiple connecting plates that are connected to the inner wall of the feed pipe 5 are fixedly installed in a ring on the outer wall of the drive bearing 9. The drive bearing 9 and the connecting plates cooperate with each other to support the feeding rod 7, which improves the stability of the feeding rod 7 when it rotates, and at the same time reduces the resistance of the feeding rod 7 when it rotates, thus improving the smoothness of the feeding rod 7 rotation.

[0036] The drive bearing 9 is located between the tension wheel and the feed plate to prevent material from accumulating on the outside of the drive bearing 9 and to avoid affecting the rotation of the drive bearing 9 when the material is fed.

[0037] An annular pipe 8 is fixedly installed on the inner wall of the feed pipe 5. Multiple air outlets connected to its own inner cavity are fixedly installed in a ring at the bottom of the annular pipe 8. The annular pipe 8 is located between the drive bearing 9 and the feed plate. An air pump 4 is fixedly installed on the outer wall of the feed pipe 5. A connecting pipe is fixedly installed at the air outlet of the air pump 4. The end of the connecting pipe away from the air pump 4 extends into the inner cavity of the feed pipe 5 and is fixedly connected to the outer wall of the annular pipe 8. After the material enters the inner cavity of the feed pipe 5, the air pump 4 is started. The air around the air pump 4 enters the inner cavity of the connecting pipe through the air inlet. The airflow enters the inner cavity of the annular pipe 8 after passing through the connecting pipe, and then enters the inner cavity of the feed pipe 5 through the multiple air outlets at the bottom of the annular pipe 8. This accelerates the air flow rate in the inner cavity of the feed pipe 5, which can blow off materials with excessive moisture or high viscosity that are attached to the inner wall of the feed pipe 5. At the same time, after feeding is completed, it can accelerate the drying rate of the inner wall of the feed pipe 5 and prevent the dried material from sticking to the inner wall when it enters the inner cavity of the feed pipe 5.

[0038] 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.
