DETAILED DESCRIPTION

[0045] The present application will now be further described in greater detail in connection with the enclosed drawings and examples, which are not to be construed as limiting the application, but which are only intended to further illustrate the basic principles thereof. The drawings show: Example 1

[0046] As shown in Figures 1-20 a feeding protection system with a feeding and mixing function, comprising a mobile platform 1, characterized in that the mobile platform 1 is provided with a mixing mechanism for feeding and mixing, and the mobile platform 1 is further provided with an airflow mill mechanism, and the mixing mechanism and the airflow mill mechanism are connected by a blanking guide pipe 3.

[0047] Specifically, the mixing mechanism comprises a grinding disc base 4 arranged on the moving platform 1, a mixing assembly 5 and a feeding assembly 16 are stacked on the grinding disc base 4 from bottom to top, a mixing cavity 501 in the mixing assembly 5 is communicated with a feeding cavity 1601 capable of premixing materials in the feeding assembly 16, a stirring assembly 41 capable of extending into the feeding cavity 1601 is movably arranged on the grinding disc base 4, a stirring shaft 14 assembled and arranged on the grinding disc base 4 in the stirring assembly 41 drives a rotating disc 6 through a sliding block coupling 15, a C-shaped stirring blade 17 fixedly connected with the end of the stirring shaft 14 is arranged in the feeding cavity 1601, a conical stirring blade 18 fixedly sleeved and arranged on the stirring shaft 14 is arranged in the mixing cavity 501, an annular rubber protective cover 40 is arranged between the conical stirring blade 18 and the rotating disc 6 in a floating manner, a plurality of discharge holes 19 are arranged at the bottom of the feeding cavity 1601, and a speed reducer 28 is arranged at the lower end of the stirring shaft 14.

[0048] The stirring shaft 14 is driven to rotate through the speed reducer 28, the C-shaped stirring blade 17 and the conical stirring blade 18 on the stirring shaft 14 respectively stir the materials in the mixing cavity 501 and the feeding cavity 1601, a large amount of materials is temporarily stored in the feeding cavity 1601, in order to prevent the materials in the feeding cavity 1601 from falling into the mixing cavity 501 through the discharge holes 19, the upper side of the C-shaped stirring blade 17 is arranged in an inclined manner, the thickness of the C-shaped stirring blade 17 gradually increases from the end to the connection with the stirring shaft 14, the C-shaped stirring blade 17 stirs the materials at the bottom of the feeding cavity 1601, so that the materials can smoothly enter the mixing cavity 501 through the discharge holes 19, and the discharge speed can be controlled by changing the rotating speed of the stirring shaft 14.

[0049] Further, in order to increase the mixing efficiency of the conical stirring blade 18 on the materials in the mixing assembly 5, a plurality of T-shaped stirring rods 20 for stirring materials are arranged on the curved surface of the conical stirring blade 18 in a horizontal manner, so as to increase the contact area between the conical stirring blade 18 and the materials, and further increase the mixing efficiency of the materials.

[0050] In the embodiment, the rotating disc 6 is movably arranged in the annular limiting groove 12 on the grinding disc base 4, the annular rotating groove 7 deviating from the mixing cavity 501 is arranged on the rotating disc 6, the material stirring blade 8 capable of penetrating into the annular rotating groove 7 and having an adjustable penetration depth is arranged on the mixing assembly 5, and the discharge port 2 communicated with the annular limiting groove 12 is further arranged on the grinding disc base 4.

[0051] The stirring shaft 14 can drive the eccentric rotation of the material rotating disc 6 through the slider coupling 15, and a part of the eccentrically driven material rotating disc 6 can be transferred out of the range of the mixing material cavity 501, so that a part of the material rotating disc 6 for the annular material rotating groove 7 is located directly below the mixing material cavity 501, and the other part can extend out of the range of the mixing material cavity 501. When the material rotating disc 6 and the conical stirring knife 18 rotate, part of the material will fall into the annular material rotating groove 7 and be transferred to the periphery of the mixing material cavity 501 with the continuous rotation of the material rotating disc 6. Then, the material in the annular material rotating groove 7 is quantitatively scooped to the discharge port 2 by extending one end of the material pushing knife 8 into the annular material rotating groove 7. In order to increase the effect and efficiency of the material pushing knife 8 in the annular material rotating groove 7, the end of the material pushing knife 8 extending into the annular material rotating groove 7 is provided with a conical material scooping groove 23 with a smooth transition from deep to shallow. The conical material scooping groove 23 is horizontally arranged on one side and forms an obtuse angle with the adjacent side. In order to adjust the depth of the material pushing knife 8 extending into the annular material rotating groove 7, the material pushing knife 8 is divided into three parts, that is, the knife head with the conical material scooping groove 23, the knife body, and the torsion ring with scales. The knife body is hollow and can be fixed on the mixing assembly 5. A part of the knife head is located in the knife body and can slide but not rotate. The knife head is also threadedly connected with the torsion ring rotatingly arranged at the other end of the knife body. By rotating the torsion ring, the depth of the knife head extending into the annular material rotating groove 7 can be controlled.

[0052] The bottom of the side wall of the mixing material cavity 501 is provided with a material pushing guide vane 21 for pushing the material into the annular material rotating groove 7. The inner wall bottom of the mixing material cavity 501 is also provided with an arc-shaped guide vane 22 for layering the material. By arranging the material pushing guide vane 21, the material in the mixing material cavity 501 driven by the T-shaped stirring rod 20 and the material rotating disc 6 can be pushed into the annular material rotating groove 7 exposed directly below the mixing material cavity 501. By arranging the arc-shaped guide vane 22, the sticky material at the bottom of the material rotating disc 6 can be scraped off during the continuous rotation of the material rotating disc 6, so as to prevent material residue. At the same time, the material in the annular material rotating groove 7 can also be extruded and smoothed by the arc-shaped guide vane 22 and the bottom of the mixing assembly 5. In order to facilitate the active embedding of the material rotating disc 6 into the annular limiting groove 12, there is a gap between the material rotating disc 6 and the annular limiting groove 12. The material in the annular material rotating groove 7 can also be scraped into the annular limiting groove 12. Therefore, in order to prevent the material from remaining in the annular limiting groove 12, the bottom side of the material rotating disc 6 is provided with a plurality of pushing pieces 13 for cleaning the residual material in the annular limiting groove 12.

[0053] The air flow mill mechanism comprises an air flow mill shell 31 communicated with the discharging guide pipe 3 through a three-way pipe 29, an assembling cavity 32 is arranged in the air flow mill shell 31, the assembling cavity 32 is embedded with an open abrasive disc 9, the open abrasive disc 9 is provided with an abrasive cavity 10 coaxially arranged with the assembling cavity 32, a tapered protrusion 11 for guiding air flow is arranged at the bottom of the abrasive cavity 10, a first air flow nozzle 38 is arranged in one lateral end of the three-way pipe 29, a feeding pipe 30 is arranged in the other lateral end of the three-way pipe 29, the feeding pipe 30 is also obliquely and sealingly mounted on the air flow mill shell 31, a countersunk cylinder 33 is arranged at the opening of the abrasive cavity 10, a negative pressure discharging pipe 34 coaxially arranged with the countersunk cylinder 33 is also sealingly mounted on the air flow mill shell 31, a plurality of obliquely and coaxially arranged air holes 35 are respectively arranged on the air flow mill shell 31 and the open abrasive disc 9, a second air flow nozzle 36 extending to the outside of the air flow mill shell 31 is arranged in the air holes 35, and one end of the feeding pipe 30 also extends into the abrasive cavity 10 through the air holes 35, a plurality of gas interfaces 37 are obliquely arranged downward at the upper part of the discharging guide pipe 3, and a combination pipe 39 for respectively introducing inert gas into the first air flow nozzle 38, the second air flow nozzle 36 and the gas interface 37 is also arranged on the moving platform 1.

[0054] Through the combination pipe 39, the combination pipe 39 is a gas conveying pipeline for conveying inert gas by assembling and splicing a plurality of gas conveying pipelines, in order to ensure the normal input and output of inert gas, a one-way valve, a pipeline filter and other devices can be installed on the combination pipe 39, and then the inert gas is introduced into the gas interface 37, the first air flow nozzle 38 and the second air flow nozzle 36 through the combination pipe 39, so that the material falling in the discharging guide pipe 3 can be blown towards the three-way pipe 29 by the inert gas sprayed from the gas interface 37, since the end of the first air flow nozzle 38 and the feeding pipe 30 is far away from the longitudinal axis of the three-way pipe 29, the material in the three-way pipe 29 can be blown into the abrasive cavity 10 by the air flow sprayed from the first air flow nozzle 38 through the feeding pipe 30, a plurality of second air flow nozzles 36 are obliquely introduced into the abrasive cavity 10 through the air holes 35, the inert gas flows at high speed in the annular cavity between the countersunk cylinder 33 and the abrasive cavity 10, and the inert gas collides with the inner wall of the abrasive cavity 10 and the outer wall of the countersunk cylinder 33 to be crushed, and the mutual collision between the materials can also achieve the effect of crushing, in order to increase the residence time of the material in the abrasive cavity 10 and increase the efficiency of the collision between the material and the abrasive cavity 10 and the collision between the material and the countersunk cylinder 33, the tapered protrusion 11 for guiding air flow is arranged at the bottom of the abrasive cavity 10, and the symmetrical section of the tapered protrusion 11 is a triangle with circular arc shapes on both sides, and the turning portions of the inner wall of the abrasive cavity 10 are all rounded.

[0055] By setting the conical bump 11 at the bottom of the abrasive cavity 10, when the airflow in the abrasive cavity 10 flows at high speed, part of the airflow will be guided by the outer arc surface of the conical bump 11, and the part of the airflow and the material will be guided vertically upward. At the same time, due to the greater floating nature of the smaller material in the airflow space, part of the fine material will enter the countersunk cylinder 33 and the negative pressure discharge pipe 34 with the airflow, but due to the arc shape of the periphery of the conical bump 11, part of the airflow will rejoin the original annular airflow, and will cause interference to the original flow direction, making it become a vortex ring airflow, bringing the material to repeatedly collide with the inner wall of the abrasive cavity 10 and the outer wall of the countersunk cylinder 33, increasing the material crushing effect.

[0056] The upper opening of the feeding cavity 1601 is also provided with a foldable sealing cover 24, and the sealing cover 24 is also provided with a pressure gauge 25 and a feeding port 2401. The mixing assembly 5 is also provided with a plurality of transparent observation plates 26, and the moving platform 1 is also provided with an electric control box 27 for controlling the running state of the detection equipment. By setting the air tightness of the sealing cover 24 device, it is ensured that the inert gas will not leak, and by introducing inert gas to protect the material, it is also convenient to observe the state of the material feeding, mixing and transfer through the transparent observation plate 26, and finally the running state of the reducer 28 and other components is controlled by the electric control box 27. Example two

[0057] As Figures 1-20 shown, on the basis of example one, a feeding method with feeding and mixing function, the device for feeding, mixing and feeding is realized, including the following steps:

[0058] Step one, the material to be mixed and crushed is placed in the feeding cavity 1601, and the C-shaped stirring knife 17 on the stirring shaft 14 rotates to preliminarily mix the material in the feeding cavity 1601, and pushes the material to fall into the mixing cavity 501;

[0059] Step two, the material in the mixing cavity 501 is further mixed by the conical stirring knife 18, and is transferred and transported by the material transfer disc 6 driven by the eccentric sliding block coupling 15, and the annular material transfer groove 7 on the material transfer disc 6 transfers the material to the periphery of the mixing cavity 501, and the material in the annular material transfer groove 7 is pushed to the discharge port 2 connected with the discharge conduit 3 by the material pushing knife 8;

[0060] Step three, the material in the feeding pipe 3 is blown by the inert gas input by the combination pipe 39 when it enters the tee pipe 29, at the same time, it is blown by the inert gas sprayed by the first gas jet nozzle 38 into the opening abrasive cavity 10 through the feeding pipe 30, and is guided by the annular gas flow formed by the second gas jet nozzle 36 in the abrasive cavity 10, collides with the sidewall of the abrasive cavity 10 and the counterbore cylinder 33 to be crushed, at the same time, part of the gas flow carrying the material is guided into the counterbore cylinder 33 and the negative pressure discharging pipe 34 through the conical bump 11 at the bottom of the abrasive cavity 10 to complete the material output, at the same time, since the conical bump 11 cannot guide all the gas flow into the counterbore cylinder 33 and the negative pressure discharging pipe 34, part of the gas flow will diffuse and blend with the annular gas flow in the abrasive cavity 10, so that the annular gas flow is changed into a vortex ring-shaped gas flow, and the material crushing effect is increased.

[0061] Working principle: the stirring shaft 14 drives the material rotating disc 6 to rotate through the eccentric driving of the sliding block coupling 15, and the mixed material is transferred through the annular material rotating groove 7 on the material rotating disc 6, and then the material is scooped out of the annular material rotating groove 7 through the material shoveling knife 8, so as to complete the material transfer between the material feeding and mixing and the material crushing, and through this method, not only the feeding amount can be accurately controlled by adjusting the distance of the material shoveling knife 8 into the annular material rotating groove 7, but also the material accumulation and blockage can be avoided, at the same time, when the material is crushed, the state of the gas flow is changed through the conical bump 11, the collision efficiency of the material with the abrasive cavity 10 and the counterbore cylinder 33 is increased, and the material crushing effect is further increased.

[0062] The above is the ideal embodiment of the present application, through the above description, the related personnel can make various changes and modifications without deviating from the technical idea of the present application.

The mixing component (5) is also provided with several transparent observation plates (26), and the mobile platform (1) is also provided with an electrical control box (27) for controlling the operating status of the detection equipment.

7. A feeding protection system with feeding and mixing function according to claim 6, characterized in that: The airflow mill mechanism includes an airflow mill housing (31) connected to the feed conduit (3) via a three-way pipe (29). An assembly cavity (32) is provided inside the airflow mill housing (31). An open abrasive disc (9) is embedded in the assembly cavity (32). An abrasive chamber (10) coaxially arranged with the assembly cavity (32) is provided on the open abrasive disc (9). A conical protrusion (11) for guiding airflow is provided at the bottom of the abrasive chamber (10). A first airflow nozzle (38) is provided in one lateral end of the three-way pipe (29), and a feed pipe (30) is provided in the other lateral end of the three-way pipe (29). The tube (30) is also obliquely sealed on the airflow mill housing (31). A countersunk cylinder (33) is provided at the opening of the abrasive chamber (10). A negative pressure discharge pipe (34) coaxially arranged with the countersunk cylinder (33) is also sealed on the airflow mill housing (31). Several oblique and coaxial vent holes (35) are respectively opened on the airflow mill housing (31) and the open abrasive disc (9). A second airflow nozzle (36) extending to the outside of the airflow mill housing (31) is installed in several vent holes (35). One end of the feed pipe (30) also extends into the abrasive chamber (10) through the vent hole (35).

8. A feeding protection system with feeding and mixing function according to claim 7, characterized in that: The upper part of the feeding conduit (3) is inclined downward and has several gas ports (37). The mobile platform (1) is also provided with a combined pipe (39) for introducing inert gas into the first airflow nozzle (38), the second airflow nozzle (36) and the gas ports (37) respectively.

9. A feeding protection system with feeding and mixing function according to claim 8, characterized in that: The inner wall of the abrasive cavity (10) is rounded at all turning points, and the symmetrical cross section of the conical protrusion (11) is a triangle with rounded sides.

10. A feeding method with a feeding and mixing function, implemented using a feeding protection system with a feeding and mixing function as described in claim 9, characterized in that: Includes the following steps: Step 1: Place the material to be mixed and crushed into the feeding chamber (1601), and rotate the C-shaped stirring blade (17) on the stirring shaft (14) to initially mix the material in the feeding chamber (1601) and push the material into the mixing chamber (501); Step 2: The material entering the mixing chamber (501) is further stirred and mixed by the conical stirring blade (18), and the material is transferred and transported by the transfer plate (6) driven eccentrically by the slider coupling (15). The annular transfer groove (7) on the transfer plate (6) transfers the material to the periphery of the mixing chamber (501), and the material in the annular transfer groove (7) is scooped towards the discharge port (2) connected to the discharge guide pipe (3) by the material-pushing blade (8). Step 3: When the material entering the feeding conduit (3) is blown towards the three-way pipe (29) by the inert gas input from the combined pipe (39), it will be simultaneously blown into the open grinding chamber (10) by the inert gas ejected by the first airflow nozzle (38) through the feed pipe (30). It will be guided by the annular airflow formed by the combined action of the airflow ejected by the second airflow nozzle (36) in the grinding chamber (10), and collide with the side walls of the grinding chamber (10) and the countersunk cylinder (33) to crush it. At the same time, the conical protrusion (11) at the bottom of the grinding chamber (10) will guide part of the airflow carrying the material into the countersunk cylinder (33) and the negative pressure discharge pipe (34) to complete the material output. Since the conical protrusion (11) cannot guide all the airflow into the countersunk cylinder (33) and the negative pressure discharge pipe (34), some of the airflow will diffuse and merge with the annular airflow in the grinding chamber (10), so that the annular airflow is transformed into a vortex-shaped airflow, which increases the crushing effect of the material.
