[0002] Qilong Capsule is a Chinese patent medicine. It is composed of Astragalus, Pheretima, Salvia miltiorrhiza, Angelica sinensis, Red Peony Root, Chuanxiong, Safflower, and Peach Kernel. It has the effects of invigorating Qi and activating blood circulation, removing blood stasis and unblocking collaterals. It is used for the recovery period of ischemic stroke (cerebral infarction), with symptoms of hemiplegia, crooked mouth and tongue, slurred speech, hemiplegia, and ecchymosis and petechiae on the tongue.

[0003] Freeze-dried powder is a sterile powder injection made by freezing the liquid medicine into a solid state under a sterile environment and vacuuming the water to sublimate and dry it. Freeze-drying is an effective preservation method for drying heat-sensitive products and substances that need to maintain biological activity. Qilong Capsule freeze-dried powder is a powder formed by freeze-drying the raw materials in a freeze dryer, which brings convenience to subsequent storage, transportation and use;

[0004] The raw materials after freeze-drying need to be recycled, that is, the freeze-dried powder of Qilong Capsules is taken out from the sample tray of the freeze dryer and transferred to a suitable place for storage. In this process, if manual scraping and pouring are used, there will undoubtedly be inefficiency, and there will be problems with the freeze-dried powder of Qilong Capsules remaining in the sample tray; therefore, when recycling the freeze-dried powder of Qilong Capsules, some people will use a vacuum cyclone dust collector for recycling, which greatly increases the recycling efficiency. However, when using a vacuum cyclone dust collector for recycling, if the recycling environment is not clean and there are dust impurities around the sample tray, it is very likely that the inhaled freeze-dried powder of Qilong Capsules is mixed with dust impurities. Since the freeze-dried powder of Qilong Capsules is a medicine, it has strict requirements on hygiene. Therefore, this method is very likely to make the freeze-dried powder of Qilong Capsules not meet the hygiene requirements and affect its use.

[0005] In view of this, the present invention solves the above technical problems by proposing a Qilong Capsule freeze-dried powder vacuum cyclone recovery device and a method of using the same. Summary of the invention

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figure 2 As shown;

[0038] The vacuum cyclone recovery device for freeze-dried powder of Qilong Capsules described in the present invention comprises: a cart 1; a cyclone dust collector 2, wherein the cyclone dust collector 2 is fixedly mounted on the cart 1, an exhaust pipe 21 is arranged on the top of the cyclone dust collector 2, an air intake pipe 22 is arranged on the side of the cyclone dust collector 2, and a collecting box 23 is detachably connected to the bottom of the cyclone dust collector 2; and further comprises: a recovery unit 3, wherein the recovery unit 3 is connected to the air intake pipe 22, and the recovery unit 3 can suck and recover the freeze-dried powder of Qilong Capsules, and reduce the suction of dust impurities during the recovery process by covering the sample tray of the freeze dryer.

[0039] During operation, freeze-dried powder is a sterile powder injection formed by freezing liquid medicine into a solid state under a sterile environment and vacuumizing the water to sublimate and dry it. Freeze-drying is an effective preservation method for drying heat-sensitive products and substances that need to maintain biological activity. Qilong Capsule Freeze-dried Powder is a powder formed by freeze-drying the raw materials in a freeze dryer, which brings convenience to subsequent storage, transportation and use. The freeze-dried raw materials need to be recycled, that is, the Qilong Capsule freeze-dried powder is taken out from the sample tray of the freeze dryer and transferred to a suitable place for storage. In this process, if manual scraping and pouring are used, there will undoubtedly be low efficiency and the problem of Qilong Capsule freeze-dried powder remaining in the sample tray; therefore, when recycling the Qilong Capsule freeze-dried powder, some people will use a vacuum cyclone dust collector 2 for recycling, which greatly increases the recycling efficiency. However, when using a vacuum cyclone dust collector 2 for recycling, if the recycling environment is not clean and there are dust and impurities around the sample tray, it is very likely There is dust impurities mixed in the inhaled freeze-dried powder of Qilong Capsules. Since the freeze-dried powder of Qilong Capsules is a medicine, it has strict requirements on hygiene. Therefore, this method is likely to make the freeze-dried powder of Qilong Capsules fail to meet the hygiene requirements and affect its use. Therefore, a recovery unit 3 is set, and the recovery unit 3 is connected to the air inlet pipe 22. The recovery unit 3 can inhale and recover the freeze-dried powder of Qilong Capsules, and reduce the inhalation of dust impurities during the recovery process by covering the sample tray of the freeze dryer. In the present application, the trolley 1 is set to facilitate the overall movement of the device, and the cyclone dust collector 2 is the vacuum cyclone dust collector 2 of the prior art. Its structure and principle can be specifically referred to the prior art. The exhaust pipe 21 is connected to the vacuum pump, and the freeze-dried powder of Qilong Capsules is inhaled from the air inlet pipe 22, and then concentrated in the collection box 23. The collection box 23 can be detachably connected to the bottom of the cyclone dust collector 2, such as a threaded connection, and the collection box 23 can be removed at regular intervals to collect the freeze-dried powder of Qilong Capsules.

[0040] As a specific embodiment of the present invention, Figure 3 , Figure 4 as well as Figure 5 As shown, the recovery unit 3 includes: a recovery rod 31, which is fixedly connected to the air intake pipe 22 through a pipeline; a recovery nozzle 311 is fixedly connected to the bottom end of the recovery rod 31, and a ring block 312 is fixedly connected to the rod body of the recovery rod 31; a No. 1 rod 32, which is four and distributed in a ring around the ring block 312, one end of the No. 1 rod 32 is connected to a right-angle block 33, and a right-angle groove 331 is provided at the bottom of the right-angle block 33; an elastic membrane 34, which is fixedly connected between the No. 1 rod 32 and the right-angle block 33. When the No. 1 rod 32 is unfolded, the elastic membrane 34 is rectangular, and the elastic membrane 34 can be a silicone film, or an elastic fiber material, such as DuPont Lycra.

[0041] like Figure 3As shown, the rod 32 is hinged to the annular block 312 and the right-angle block 33 through a ball chain, and the rod 32 is a telescopic rod.

[0042] The right-angle block 33 is a permanent magnet.

[0043] During operation, when the freeze-dried powder of Qilong Capsules in the freeze dryer sample tray needs to be recovered, since the sample tray is a rectangular tray, such as Figure 1 As shown, the rod 32 and the right-angle block 33 are rotated, and the right-angle groove 331 at the bottom of the right-angle block 33 is aligned with the four corners of the sample tray, so that the four corners of the sample tray are inserted into the right-angle groove 331. Since the right-angle block 33 is a permanent magnet and the sample tray is made of magnetic material, the four corners of the sample tray are inserted into the right-angle groove 331, so that the right-angle block 33 can be well fixed at the four corners of the sample tray. Since the elastic membrane 34 is fixedly connected between the rod 32 and the right-angle block 33, the rod 32 cooperates with the elastic membrane 34 so that the elastic membrane 34 wraps the top of the sample tray, that is, the rod 32, the elastic membrane 34 and the sample tray form a closed area; then the recovery nozzle 311 absorbs the freeze-dried powder of Qilong Capsules to isolate it from external dust, which relatively ensures The cleanliness of the inhaled freeze-dried powder of Qilong Capsules is improved to reduce the inhalation of external dust. Of course, an opening is provided at the position of the elastic membrane 34 near the annular block 312, and a filter is provided at the opening to ensure that the area between the elastic membrane 34 and the sample tray is connected to the external atmospheric pressure, thereby ensuring the normal operation of the recovery nozzle 311; it should be noted that the No. 1 rod 32 is hinged with the annular block 312 and the right-angle block 33 through a ball chain, and the No. 1 rod 32 is a retractable rod. The purpose is to enable the recovery unit 3 to adapt to sample trays of different sizes through the rotation of the ball chain and the extension and retraction of the No. 1 rod 32 to different lengths, and to ensure that the recovery rod 31 can move, so as to facilitate the recovery nozzle 311 to recover the freeze-dried powder of Qilong Capsules at various places on the sample tray.

[0044] As a specific embodiment of the present invention, Figure 3 As shown, the cross section of the recovery nozzle 311 is trapezoidal.

[0045] During operation, since the freeze-dried powder of Qilong Capsules after freeze-drying in the freeze dryer is loose and porous, and condensed in a sponge-like state at the bottom of the sample tray, the recovery nozzle 311 has a trapezoidal cross-section, which can effectively scrape the freeze-dried powder of Qilong Capsules and absorb it through the recovery nozzle 311. Since the No. 1 rod 32 is hinged with the annular block 312 and the right-angle block 33 through a ball chain, the No. 1 rod 32 is a retractable rod. With the rotation of the ball chain and the extension and retraction of the No. 1 rod 32, the recovery rod 31 can move along the bottom of the sample tray, and then the recovery nozzle 311 can move along the bottom of the sample tray. With the trapezoidal cross-section of the recovery nozzle 311, the recovery nozzle 311 can effectively scrape the freeze-dried powder of Qilong Capsules and recycle it.

[0046] As a specific embodiment of the present invention, Figure 6As shown, the recovery rod 31 is composed of a mother rod 313 and a child rod 314. The child rod 314 is nested in the mother rod 313. A No. 1 cavity 315 is formed between the inner part of the mother rod 313 near the bottom end and the outer wall of the child rod 314. A No. 1 spring 316 is arranged in the No. 1 cavity 315. The No. 1 spring 316 is fixedly connected to the outer wall of the child rod 314 and the inner wall of the mother rod 313.

[0047] like Figure 8 As shown, two elastic tubes 35 are provided at the bottom of the right-angle block 33, and each of the elastic tubes 35 is fixedly connected to the inner wall of each right-angle groove 331 so that the elastic tube 35 is in a square shape; the elastic tubes 35 between adjacent right-angle blocks 33 are fixedly connected to the elastic membrane 34; the No. 1 rod 32 and the elastic tube 35 are both hollow structures, and the No. 1 rod 32, the elastic tube 35 and the No. 1 cavity 315 are connected.

[0048] like Figure 6 as well as Figure 7 As shown, one end of the sub-rod 314 away from the recovery nozzle 311 is fixedly connected to a No. 1 ring 36 .

[0049] When the bottle cap 310 is in the airtight position, the spring 316 is pressed against the bottle cap 314, and the bottle cap 310 is in the airtight position, so that the bottle cap 310 is in the airtight position, and the bottle cap 310 is in the airtight position. The structure is that the No. 1 rod 32, the elastic tube 35 and the No. 1 cavity 315 are interconnected. Therefore, when the space of the No. 1 cavity 315 is reduced, the elastic tube 35 expands and squeezes the side wall of the sample tray, so that the elastic tube 35 is in closer contact with the side wall of the sample tray, further reducing the possibility of the elastic membrane 34 falling off and dust entering. In addition, the end of the sub-rod 314 away from the recovery nozzle 311 is fixedly connected to the No. 1 ring 36. The addition of the No. 1 ring 36 makes the opening of the No. 1 ring 36 smaller than the inner diameter of the sub-rod 314. When the Qilong Capsule freeze-dried powder is inhaled, the airflow and the blowing of the Qilong Capsule freeze-dried powder cause the sub-rod 314 to move slightly toward the inside of the mother rod 313, thereby slightly squeezing the No. 1 cavity 315, and then the elastic tube 35 expands and squeezes the inner wall of the sample tray. Therefore, when the device is started, even if the recovery rod 31 does not move with the sample tray, the elastic tube 35 can be close to the side wall of the sample tray, ensuring the sealing and connection stability.

[0050] A method for using the vacuum cyclone recovery device for freeze-dried powder of Qilong Capsules as described above comprises the following steps:

[0051] S1: Rotate the No. 1 rod 32 and the right-angle block 33, and align the right-angle groove 331 at the bottom of the right-angle block 33 with the four corners of the sample tray, so that the four corners of the sample tray are inserted into the right-angle groove 331, and the No. 1 rod 32 cooperates with the elastic film 34, so that the elastic film 34 wraps the upper part of the sample tray;

[0052] S2: The exhaust pipe 21 is connected to a vacuum pump, and the freeze-dried powder of Qilong Capsules is sucked in from the air inlet pipe 22 and then collected in a collection box 23. The collection box 23 is detachably connected to the bottom of the cyclone dust collector 2, and the collection box 23 can be removed at regular intervals to collect the freeze-dried powder of Qilong Capsules;

[0053] S3: When the recovery rod 31 moves along the sample tray and the device is started, the space of cavity No. 1 315 shrinks, and the elastic tube 35 expands, squeezing the side wall of the sample tray, so that the elastic tube 35 is in closer contact with the side wall of the sample tray, further reducing the possibility of the elastic membrane 34 falling off and dust entering, ensuring the sealing and connection stability.
