Description

Technical Field

[0001] The present invention relates to the technical field of biological food and pharmaceutical fine processing, and specifically to a centrifugal nano-microporous vibrating sieve machine. Background Art

[0002] In the development process of the biological food and medicine field, screening equipment is required to filter the biological powder after grinding or cell wall breaking in order to isolate the fine substances beneficial to the human body. The ultra-fine screening and filtering technology of biological powder plays a decisive role in the application of biological foods and medicines in the dry state. To screen powders with a mesh size above 12,500 meshes, a screening device with the same sieve holes and a matching device must be manufactured; another problem is that to achieve the effect of direct absorption of the powder by the human body, the fineness of the biological powder must reach the ultra-fine state of 12,500 meshes. With the current technology, the corresponding pore diameter of the filtering sieve holes can be achieved, but when the micropores are too fine, the screening cannot be completed by the traditional vibrating sieve method, and the powder will only stay on the surface and cannot pass through the too-fine micropore channels.

[0003] Therefore, the technical personnel in this field have provided a centrifugal nano-microporous vibrating sieve machine to solve the problems raised in the above background art. Summary of the Invention

A negative pressure cover lock is fixedly installed on the outer surface of the negative pressure cover, and an air filter element is fixedly installed inside the negative pressure intake valve.

[0007] Preferably, a feed inlet protective cover is sleeved on the outer surface of the feed inlet.

[0008] Preferably, the columns of the horizontal frame are four-column feet perpendicular to the ground. The front and back sides use single beams up and down, and the left and right sides use double beams up and down. Vibration springs are arranged between the double beams and are fixedly arranged between the upper and lower double beams respectively. The vibration springs on the left and right sides of the upper and lower layers are equal to each other, forming upper and lower opposing matching vibration springs on the left and right sides, which are divided into upper springs and lower springs and are respectively arranged and fixed with the upper and lower double beams. The vibration box supports are inserted in the middle of the upper spring and the lower spring and then fixed. The eight vibration box supports are respectively connected and fixed with the upper and lower springs to form a suspended matching.

[0009] Preferably, the vibration box is a square box body, and the diameter of the top of the upper cone of the centrifugal barrel is smaller than the diameter of the bottom end.

[0014] Preferably, the spiral channels provided inside the lower cone of the centrifugal barrel are distributed on the left and right sides and lead directly to the middle diversion pipe hole in a spiral manner inward and downward.

[0015] Compared with the prior art, the present invention provides a centrifugal nano-microhole vibrating sieve machine, which has the following beneficial effects:

[0016] 1. For this centrifugal nano-microhole vibrating sieve machine, the microhole precision of the stainless steel sieve plate after laser processing can be controlled at more than 12,500 meshes at most. The sieve plates can be selected and installed according to different material component properties. The biological powder can be sieved into ultra-fine powder with more than 12,500 meshes at most, such as the powder of the roots, stems, leaves, flowers and pollen of plants. The sieve plates are arranged in three layers: inner, middle and outer. The inner layer isolates the coarse powder, the middle layer isolates the medium powder, and the outer layer isolates the fine powder. Finally, the ultra-fine powder falls into the conical centrifugal barrel. After being evenly distributed by the three-layer sieve plates, the gravity of the material powder on the sieve plates generated during the rotation of the conical sieve barrel is dispersed and reduced.

[0017] 2. The centrifugal nano-microporous vibrating screen machine adopts an upright conical screen layout for rotation. The centrifugal force generated by the rotation throws the material powder to the surroundings and contacts the screen to generate friction, forming an extrusion effect on the screen surface of the material powder. At the same time, through the vibration force of the vibrator on the top of the vibration box, the fine powder of the material forms a tumbling and staggered extrusion of the screen barrel with the inner wall of the screen barrel. At the same time, after the conical centrifugal barrel rotates at a high speed, the material receiving wrist at the bottom forms friction with the air in the conical centrifugal barrel, and negative pressure is generated in the conical centrifugal barrel. The intake valve adjusts the appropriate intake volume state, and the appropriate amount of air sucked in through the filter element in the intake valve enters the conical screen barrel. In the process of air being discharged outward around the screen barrel, the ultra-fine powder attached to it is discharged to the outer layer, and flows into the conical centrifugal barrel after passing through the first, second and third layers of screen cylinders. The conical centrifugal barrel generates outward and downward centrifugal force through synchronous high-speed rotation, and discharges the ultra-fine powder along the receiving wrist mouth to the spiral channel, and finally flows into the receiving pocket set in the middle guide pipe and falls into the receiving port for collection.

[0018] 3. After the centrifugal nano-porous vibrating screen machine stops, the ultra-fine powder is screened and collected, and then the material collection bag is taken out and replaced with a bag for collecting residual materials. The electromagnetic suction cup switch button is turned on. At this time, the guide tube is upward, and the equipment reverse unloading mode is started. The conical centrifugal barrel is reversed, and the inner, middle and outer three-layer unloading wrists set in the conical screen cylinder start to work, which can automatically discharge the coarse powder remaining in the screen barrel through the spiral channel to the middle guide tube downward.

The circular hollow part provided inside the conical centrifugal bucket lower cone is the activity space of the movable limit disc 20, which plays a role in limiting the "ascending and descending" of the movable limit disc;

[0055] A base bearing 22 is sleeved on the outer surface of the guide pipe 21. An electromagnetic chuck 23 is fixedly installed on the outer surface of the guide pipe 21. A secondary chuck 24 and a discharge pocket fixing device 25 are fixedly installed on the outer surface of the guide pipe 21 from top to bottom respectively. At the top of the centrifugal bucket upper cone 10, a feed inlet 33 is fixedly installed. A feed inlet protective cover 4 is sleeved on the outer surface of the feed inlet 33. At the top of the feed inlet 33, a negative pressure intake valve 26 is fixedly installed. At the center of the upper surface of the conical sieve bucket lower bottom 14, a centrifugal cone 28 is fixedly connected. On the outer surface of the outer sieve bucket 17, conical bucket frame columns 27 are fixedly connected at equal intervals. The inner sieve bucket 15, the middle sieve bucket 16 and the outer sieve bucket 17 are three forms of nano-microporous sieve sheets.

The inner vertical surface is provided with a nano-microporous sieve sheet fixing wire groove, and the wire groove extends from the top to the bottom. The nano-microporous sieve sheet is made of stainless steel and titanium alloy plates. The wire groove opening at the upper end of the conical bucket frame column 27 corresponds precisely to the wire groove port of the conical sieve bucket upper bottom 18. The radian of the inner and outer surfaces of the conical bucket frame column 27 is consistent with the radian of the nano-microporous sieve sheet.

[0057] Please refer to the appendix Figure 2 - appendix Figure 21 At the center of the top of the vibration box 2, a negative pressure cover 9 is fixedly installed inside the gearbox 3. A moving positioning rib 30 is fixedly installed on the outer surface of the diversion pipe 21. A moving positioning groove 29 that matches the moving positioning rib 30 is opened inside the diversion base 13. A negative pressure cover lock 31 is fixedly installed on the outer surface of the negative pressure cover 9. An air filter element 32 is fixedly installed inside the negative pressure air inlet valve 26. The size of the intake air is adjusted through the intake valve provided in the middle of the top of the negative pressure cover 9. After passing through the adjusted intake valve, a certain amount of air enters the inner layer of the conical sieve barrel. While the air gradually diffuses outward after entering, it cooperates with the centrifugal force generated by the rotation of the conical centrifugal barrel and the vibration force generated by the vibrator 8 to perform three different functions, discharging the ultrafine powder attached to the nano sieve sheet into the nano micropores. Through the formation of a convergence inside the outer conical centrifugal barrel, finally, the sieved ultra-fine powder flows into the collection pocket together with the air. The air is discharged after being filtered by the collection pocket, and the ultra-fine powder adheres to the inner wall for collection after entering the collection pocket. Embodiment 3

[0058] For the screening operation process of the present invention, please refer to Figure 1 、appendix Figure 4 、appendix Figure 5 、appendix Figure 6 、appendix Figure 22 、appendix Figure 23 、appendix Figure 24 、appendix Figure 25 、appendix Figure 32 、appendix Figure 33As shown in the figure, the material powder is crushed and then added to the feed inlet 33. Next, the negative pressure cover 9 is sealed and locked. The negative pressure intake valve 26 set in the sealed negative pressure cover 9 is opened and adjusted to the intake volume, and then the intake valve is locked. Further, the feed inlet protective cover 4 is covered to prevent injury accidents during rotation. Synchronously, the material powder passes through the feed inlet and then passes through the top cover 19 of the conical centrifuge barrel directly to the inner sieve barrel 15 of the conical centrifuge barrel. The center of the feed inlet 33, the center of the conical centrifuge barrel, and the center of the lowest discharge port are on the same straight line, and the vertical line is perpendicular to the ground. The material powder entering the conical inner sieve barrel 15 accumulates at the bottom of the conical inner sieve barrel 15. When the conical centrifuge barrel rotates forward, it drives the material powder staying at the bottom of the conical inner sieve barrel 15 to spread around the nano-micro pore sieve barrel in the "upward and outward" manner. More preferably, the material powder is filtered and screened into the middle sieve barrel 16 through centrifugal force and vibration force. Similarly, as the powder gradually overflows to the outer layer, it gradually becomes ultra-fine. Synchronously, under the high-speed rotation of the conical centrifuge barrel, the conical centrifuge barrel gradually generates air negative pressure. The air passes through the mesh holes provided at the top of the feed inlet protective cover 4, and the air passing through the negative pressure intake valve 26 is filtered by the air filter element 32 and enters the inner sieve barrel 15. More preferably, due to the negative pressure generated by the high-speed rotation of the conical centrifuge barrel, after the air enters at the top, the material powder staying around the inner sieve barrel 15, the middle sieve barrel 16, and the outer sieve barrel 17 is under the action of three external forces: the centrifugal force of outward expansion, the vibration force of up and down, and the negative pressure inside. The powder adhering to the nano-micro pore sieve sheet is discharged through the first-layer, second-layer, and third-layer nano-micro pore sieve barrels. More preferably, under the rotation of the conical centrifuge barrel, the filtered ultra-fine powder is collected in the "outward and downward" manner. Under the action of the centrifugal force and negative pressure generated during the forward rotation of the conical centrifuge barrel, the centrifugal barrel receiving wrist opening 12 provided at the bottom preferably sucks the ultra-fine powder into the wrist opening. The centrifugal barrel receiving wrist opening 12 transfers the ultra-fine powder to the diversion pipe 21 in the "downward and inward" spiral manner through the spiral channel. More preferably, the discharging pocket fixing device 25 provided at the tail discharge port of the diversion pipe 21 is bundled and connected to the receiving pocket to receive the sieved ultra-fine powder. Finally, the sieved ultra-fine powder enters the receiving pocket after passing through the discharge port. After the receiving pocket discharges the air, the ultra-fine powder is left, thus completing the sieving and collection process. Example 4

[0059] The rough material unloading operation process of the present invention: Please refer to the attached Figure 4 , attached Figure 6 , attached Figure 9 , attached Figure 10 , attached Figure 19 , attached Figure 20 , attached Figure 24 , attached Figure 25 , attached Figure 26 , attached Figure 27 , attached Figure 28 , attached Figure 29 , attached Figure 30, Attachment Figure 31 As shown, the technical measures for unloading the remaining coarse powder remaining in the conical screen barrel are also discharged to the discharge port at the lower end in a spiral manner, so the discharge port and the discharge port share an outlet. When the equipment stops the screening process, it switches to the discharge mode. At this time, the power switch of the electromagnetic suction cup 23 is turned on, and the electromagnetic suction cup 23 starts to work, absorbing and merging the auxiliary suction cup 24 at the lower end to form a whole. While the auxiliary suction cup 24 rises, it drives the guide tube 21 to move upward, and the six holes at the upper end of the guide tube 21 are directly opposite to the lower outlet of the spiral holes of the guide base 13. At this time, the unloading spiral channel is in a smooth state. Synchronously, when the guide tube moves upward, the left and right holes at the lower end of the guide tube are staggered with the outlet of the spiral channel to form a closed state. Further, the equipment is started in a reverse unloading operation mode. When the conical screen barrel is reversed, the inner, middle and outer collecting wrists arranged at the bottom of the conical screen barrel synchronously collect the remaining coarse powder and send it into the spiral channel. Synchronously, the guide tube 21 is used to discharge the remaining coarse powder from the spiral channel holes "downward and inward" along the spiral channel to the unloading port.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
