Abstract
Description
Technical Field
[0001] The invention relates to the technical field of potassium superoxide preparation, and in particular to a potassium superoxide conveying device. Background Art
[0002] Potassium superoxide is an inorganic compound and a primary oxidant, mainly used for emergency rescue in coal mines. After its preparation, some material lumps will be produced. These lumps are not tightly combined. Usually, they can be broken by gently pressing, but these lumps will affect subsequent transportation, packaging and other operations. There are usually two ways to remove these lumps. One is to use a rotary vibrating screen to screen out the lumps, and then crush the lumps separately, but this method increases the processing steps and also increases the cost. The other is to use a rotary screening device. Since this device will lift the material to a certain height during the rotation process, the lumps can collide with the screen body or the material after falling to achieve crushing, and can be crushed by friction with other materials. There will be no additional processing steps, but the rotary screening device is open and easy to fall into foreign matter and pollute the material. Summary of the invention

[0049] A feed pipe 313 is fixedly mounted on the side wall of the upper shell 310 , and the feed pipe 313 is located between the second screen 330 and the first screen 317 .
[0050] The structure of the upper housing 310 is as follows: Figure 3 and attached Figure 5 As shown, a discharge pipe 306 is fixedly installed on the top, and the discharge pipe 306 is connected to the first pipeline through a first soft connection 307; a first edge 320 is arranged at the bottom of the upper shell 310.

[0052] The structure of the first limiting member 311 is shown in the attached figure. Figure 6 As shown, it is an arc-shaped plate structure.
[0053] As attached Figure 5 and attached Figure 6As shown, a plurality of insertion holes 321 are further provided on the side wall of the upper housing 310, and these insertion holes 321 correspond one-to-one with the first stopper 311 and are located below the first stopper 311. A second stopper 312 corresponding one-to-one with the insertion holes 321 is fixedly mounted on the outer side wall of the upper housing 310, and a T-shaped insertion rod 324 capable of passing through the insertion holes 321 is provided on the second stopper 312.
[0054] The second screen 330 is disposed between the first limiting member 311 and the T-shaped insert rod 324 .

[0057] The first end of the T-shaped plug rod 324 is also fixedly mounted with a sealing sheet 327 and a sealing gasket 328 in sequence, wherein the sealing gasket 328 is made of rubber material, and the sealing sheet 327 is made of hard plastic or metal material. The sealing gasket 328 is located between the sealing sheet 327 and the side wall of the upper shell 310, and a gap is left between the sealing gasket 328 and the end of the first end of the T-shaped plug rod 324.
[0058] The first end of the T-shaped plug rod 324 is also sleeved with a second spring 326, and the two ends of the second spring 326 are respectively against the sealing sheet 327 and the barrier 329, and are always in a compressed state. This structure allows the sealing sheet 327 to always abut against the side wall of the upper shell 310 during the operation of the crushing mechanism 3, thereby sealing the plug hole 321, and also ensuring the stability of the second screen 330.
[0059] The first end of the T-shaped rod 324 is provided with two positioning holes 325 along the length direction thereof, and the latch pin 323 passes through the limiting frame 322 and one of the positioning holes.

After all the second stoppers 312 have been subjected to the above operations, the second screen 330 can be removed.
[0062] As attached Figure 3 , Attachment Figure 5 , Attachment Fig.12 As shown, a first edge 320 is provided at the bottom of the upper shell 310 , a second edge 339 matching the first edge 320 is provided at the top of the lower shell, and an air inlet 315 matching the second soft connection 308 is provided at the bottom of the lower shell.
[0063] The connection method between the upper shell 310 and the lower shell is as shown in the attached Figure 3 and attached Figure 4 As shown, an annular third limiting member 319 is provided between the upper shell 310 and the lower shell. The third limiting member 319 is located between the first edge 320 and the second edge 339 , and an installation groove is provided on its inner wall, the opening of which faces the axis of the third limiting member 319 .
[0064] The edge of the first screen 317 is located in the installation groove, and a sealing ring 318 is installed between the edge of the first screen 317 and the inner wall of the installation groove.
[0065] The structure of the first screen 317 is shown in the attached Fig.11 As shown, it includes a second frame 334 and a second sieve hole 335 arranged inside the second frame 334. An annular support tube 337 is fixedly installed on the bottom edge of the second frame 334, and an annular limiting ring 338 is fixedly installed on the bottom of the support tube 337. The inner diameter of the limiting ring 338 is equal to the inner diameter of the support tube 337, and the outer diameter is larger than the outer diameter of the support tube 337 and also larger than the outer diameter of the second frame 334.
[0066] The limiting ring 338 is located in the installation groove; the aforementioned sealing ring 318 is installed between the limiting ring 338, the supporting tube 337 and the inner wall of the installation groove.
[0067] The structure of the second screen 330 is shown in the attached figure. Fig. 9 As shown, it includes a first frame 331 and a first sieve hole 332 arranged inside the first frame 331 , wherein the first frame 331 is located between the first limiting member 311 and the first end of the T-shaped insert rod 324 .
[0068] As attached Fig. 9 and attached Fig.10 As shown, a plurality of first crushing cones 333 are fixedly mounted on the side of the second screen 330 facing the first screen 317 .
[0069] As attached Fig.11 As shown, a plurality of second crushing cones 336 matching the first crushing cones 333 are fixedly mounted on the side of the first screen 317 facing the second screen 330 .
[0070] The first crushing cone 333 and the second crushing cone 336 are arranged alternately, and a distance is left between the bottom of the first crushing cone 333 and the top of the second crushing cone 336 .
[0071] In this embodiment, the Fig. 9 To Attachment Fig.11 Only some first crushing cones 333 and second crushing cones 336 are shown. The number and density of the first crushing cones 333 and second crushing cones 336 can be designed according to actual needs.
[0072] The first edge 320 abuts against the top of the third position-limiting member 319 , and the second edge 339 abuts against the bottom of the third position-limiting member 319 .
[0073] The first edge 320 and the second edge 339 are fixed by a clamp 314, so that the upper shell 310, the first screen 317 and the lower shell are fixed.
[0074] When in use, the vibration motor and the first fan 2 are turned on; the first fan 2 provides a strong airflow, and the material to be transported enters between the first screen 317 and the second screen 330 from the feed pipe 313. The material particles will "boil" under the action of the strong airflow, then fly up, pass through the first screen 317, and then enter the cyclone separator 8 through the first pipeline. The material agglomerates will jump between the first screen 317 and the second screen 330, and collide with the first screen 317, the second screen 330, the first crushing cone 333, and the second crushing cone 336. After being crushed into a size matching the first screen hole 332, they are blown into the first pipeline. In this process, the airflow provided by the first fan 2 can also cool the material.
[0075] In order to improve the crushing effect of material agglomerates, the structure of the first crushing cone 333 is as shown in the following figure. Fig.14 As shown, the whole is conical, and is composed of six wedge-shaped wedge saw blades 344 surrounding the central axis and fixed together in a circular array. The wedge saw blades 344 can also be three or four, and the material can be metal or wear-resistant plastic, such as polytetrafluoroethylene.
[0076] The large diameter end of the first crushing cone 333 is fixedly connected to the second screen 330 .
[0077] The structure and installation method of the second crushing cone 336 are the same as those of the first crushing cone 333 .
[0078] Since the wedge-shaped saw blade 344 is provided with a plurality of saw teeth, the material agglomerates are crushed more effectively when they collide with the first crushing cone 333 and the second crushing cone 336 .
[0079] Of course, the first crushing cone 333 and the second crushing cone 336 may also adopt common cone structures, such as circular cones, polygonal cones, etc.
[0080] In order to further optimize the crushing effect of material agglomerates, the crushing mechanism 3 also includes an auxiliary crushing disk 316, whose structure is as shown in the attached figure. Figure 3 and attached Fig.13 As shown, it includes an annular third frame 340 , and the difference between the outer diameter and the inner diameter of the third frame 340 is equal to the difference between the outer diameter and the inner diameter of the limiting ring 338 .
[0081] The third frame 340 is located in the installation groove and between the limiting ring 338 and the bottom wall of the installation groove.
[0082] A cross-shaped mounting frame 341 is installed in the third frame 340 , and a plurality of cup rings 342 are fixedly installed on the mounting frame 341 . The top of the cup ring 342 is open, and two crushing balls 343 are placed inside.
[0083] During use, due to the action of the vibration motor, the crushing ball 343 will bounce in the cup ring 342 and knock the first screen 317. This is more conducive to the crushing of material lumps and can also prevent material powder from clogging the first screen 317.
[0084] In order to prevent the crushing ball 343 from escaping from the cup ring 342 , the top of the cup ring 342 abuts against the first screen 317 . Of course, there may be a gap between the top of the cup ring 342 and the first screen 317 , and the size of the gap is smaller than the diameter of the crushing ball 343 .
[0085] The shape of the aforementioned mounting frame 341 may also be other shapes, such as triangular, radial, etc.
[0086] The structure of the aforementioned air conveyor is shown in the attached Figure 1 and attached Fig.15 As shown, it includes a conveyor 5 whose first end is fixedly connected to the air outlet end of the second fan 4.
[0087] The conveyor 5 includes a conveying pipe 506, at the first end of which a feed bin 505 and a second air inlet pipe 502 are fixedly mounted and communicated with the conveying pipe 506. A bin opening 504 is provided at the top of the feed bin 505, which is communicated with the discharge end at the bottom of the buffer bin 7.
[0088] An inclined material guide plate 503 is fixedly installed inside the feed bin 505, and its inclination direction is toward the second end of the conveying pipe 506. The bottom of the material guide plate 503 extends into the conveying pipe 506 and is fixedly connected to the inner wall of the conveying pipe 506.
[0089] The axis of the second air inlet pipe 502 coincides with the axis of the delivery pipe 506, and a nozzle 501 is fixedly installed at the second end thereof, and the diameter of the nozzle 501 is smaller than the diameter of the second air inlet pipe 502. The first end of the second air inlet pipe 502 is fixedly connected to the air outlet end of the second fan 4.
[0090] The end of the air nozzle 501 passes through the material guide plate 503 .
[0091] The second end of the delivery pipe 506 is fixedly connected to the second pipeline.
[0092] The material in the buffer bin 7 flows down along the material guide plate 503 , is then blown into the second pipeline by the air flow sprayed from the air nozzle 501 , and finally enters the packaging machine 6 .
[0093] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
