Description

Technical Field

[0001] This utility model relates to the field of airflow classification technology, specifically a Ganoderma lucidum spore powder airflow classification device. Background Technology

[0002] Airflow classification is a particle separation process that utilizes the difference in settling velocity (see settling) of particles in an airflow. By reducing the flow velocity and changing the flow direction, the airflow carrying powder particles causes coarse particles to settle while carrying away fine particles, thus separating coarse and fine powder particles.

[0003] A search revealed a patent document with publication number CN 215313950 U, which discloses an airflow grading device for Ganoderma lucidum spore powder. The device includes a housing with an installation plate fixedly mounted on its outer wall. An air blowing device is fixedly mounted on the top of the installation plate and connected to the housing via the installation plate. One end of the air blowing device has an air pipe that extends through the outer wall of the housing and into the interior of the housing, connecting to a hollow air outlet pipe. The other end of the air pipe extends through the outer wall of the hollow air outlet pipe into its interior. The hollow air blowing device disperses the airflow within the housing, effectively improving airflow control and reducing the problem of poor spore powder grading results due to inadequate airflow control. This significantly improves the quality of spore powder grading, enhances the ease of collection after grading, increases work efficiency, reduces worker workload, minimizes spore powder waste, and effectively saves economic costs.

[0004] Although the aforementioned prior art can perform airflow grading of Ganoderma lucidum spore powder, the airflow diffuses in an umbrella shape when it is blown out at the end of the air outlet, causing the graded Ganoderma lucidum spore powder to be distributed in a ring. Furthermore, the parallel linear arrangement of the receiving trough in the aforementioned prior art results in a difference in particle size between the Ganoderma lucidum spore powder at both ends of the guiding trough and the Ganoderma lucidum spore powder in the middle, affecting the uniformity of grading. Utility Model Content

[0005] The purpose of this invention is to provide a Ganoderma lucidum spore powder airflow grading device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A Ganoderma lucidum spore powder airflow grading device includes a support frame, a box fixedly connected to the top of the support frame, multiple annular material collection grooves at the bottom of the box, an air inlet pipe rotating through the middle of the box from bottom to top, a connecting pipe connected to the bottom end of the air inlet pipe via a rotating pipe joint, the connecting pipe being fixedly connected to the output end of a fan, the fan being fixedly connected to the bottom inner side of the support frame, a flared mouth fixedly connected to the top of the air inlet pipe, an arc-shaped dust filter screen fixedly connected to the inner side of the box above the flared mouth, an air outlet at the top of the box, and a filling hopper embedded at the top of the box, the filling hopper penetrating the arc-shaped dust filter screen and its outlet corresponding to the flared mouth.

[0008] As a further embodiment of this utility model: the bottom of each of the annular receiving troughs is provided with a discharge pipe, and a collection tank is threadedly connected to each discharge pipe.

[0009] As a further embodiment of this utility model: a motor is fixedly installed at the bottom of the box, a first gear is fixedly connected to the output end of the motor, a second gear is fixedly connected to the outer wall of the air inlet pipe, the second gear meshes with the first gear for transmission, a rotating arm is fixedly connected to the upper outer wall of the air inlet pipe, and a matching scraper is fixedly connected to the bottom surface of the rotating arm to each annular material collection groove, and the scraper is inserted into the corresponding annular material collection groove.

[0010] As a further improvement of this utility model: a wind-breaking cone is suspended below the filling hopper by a hanger rod, and the wind-breaking cone is inserted into the horn mouth and is adapted to the horn mouth.

[0011] As a further improvement of this utility model: the top edge of the filling hopper is provided with a filling port, and a cover is threaded onto the filling port.

[0012] As a further improvement of this utility model: a vertical shaft is movably connected through the middle of the filling hopper, and a sealing plug that is compatible with the discharge port of the filling hopper is fixedly connected to the bottom end of the vertical shaft.

[0013] As a further improvement of this utility model: a rotating handle is fixedly connected to the top of the vertical shaft, and a toggle blade is fixedly connected to the edge of the sealing block.

[0014] As a further improvement of this utility model: the annular receiving troughs are concentrically arranged, and the top of each annular receiving trough is provided with a guiding ramp.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses a fan to blow air into the air inlet pipe and out through the horn, thereby forming an umbrella-shaped airflow inside the box. When Ganoderma lucidum spore powder is added to the feeding hopper, the Ganoderma lucidum spore powder is blown by the airflow and forms a grade, falling into different annular collection troughs for collection. Compared with parallel collection troughs, this effectively improves the uniformity of Ganoderma lucidum spore powder in the troughs.

[0017] 2. The motor, in conjunction with the first and second gears, can drive the rotating arm to rotate, thereby causing the scraper to move in a ring within the annular receiving trough to scrape the wall and push the material, thus facilitating the discharge of the graded Ganoderma lucidum spore powder from the discharge pipe.

[0018] 3. Setting a sealing plug in the feeding hopper can prevent Ganoderma lucidum spore powder from falling directly during feeding. At the same time, the rotation of the leaf can easily disturb the Ganoderma lucidum spore powder in the feeding hopper, making it easier to discharge. Attached Figure Description

[0024] 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.

[0025] Please see Figures 1-4 In this embodiment of the present invention, a Ganoderma lucidum spore powder airflow grading device includes a support frame 1, a box 2 fixedly connected to the top of the support frame 1, a plurality of annular material collection grooves 3 provided at the bottom of the box 2, an air inlet pipe 5 rotatably connected from bottom to top in the middle of the box 2, a connecting pipe 7 connected to the bottom end of the air inlet pipe 5 through a rotating pipe joint 6, the connecting pipe 7 being fixedly connected to the output end of a fan 8, the fan 8 being externally connected to a power supply and a switch, the air inlet of the fan 8 being provided with a dust filter structure to reduce the influence of air impurities, the fan 8 being fixedly connected to the bottom inner side of the support frame 1, a flared mouth 9 being fixedly connected to the top of the air inlet pipe 5, an arc-shaped dust filter screen 10 being fixedly connected to the inner side of the box 2 above the flared mouth 9, an air outlet 11 being provided at the top of the box 2, and a filling hopper 12 being embedded at the top of the box 2, the filling hopper 12 penetrating the arc-shaped dust filter screen 10 and its outlet corresponding to the flared mouth 9.

[0026] Air is blown into the air inlet pipe 5 by the blower 8 and blown out through the horn 9, thus forming an umbrella-shaped airflow inside the box 2. When Ganoderma lucidum spore powder is added to the feeding hopper 12, the Ganoderma lucidum spore powder is blown by the airflow and formed into a grade, falling into different annular collection troughs 3 for collection. Compared with parallel collection troughs, this effectively improves the uniformity of Ganoderma lucidum spore powder in the trough.

[0027] The bottom of the annular receiving trough 3 is provided with a discharge pipe 13, and a collection tank 14 is threadedly connected to the discharge pipe 13. The outer wall of the discharge pipe 13 is provided with external threads, and the inner wall of the opening of the collection tank 14 is provided with internal threads.

[0028] The collecting jar 14 allows for the collection of graded Ganoderma lucidum spore powder, and it can also be easily removed and replaced.

[0029] A motor 15 is fixedly installed at the bottom of the housing 2. A first gear 16 is fixedly connected to the output end of the motor 15. A second gear 17 is fixedly connected to the outer wall of the air inlet pipe 5. The second gear 17 meshes with the first gear 16 for transmission. A rotating arm 26 is fixedly connected to the upper outer wall of the air inlet pipe 5. A matching scraper 27 is fixedly connected to the bottom surface of the rotating arm 26 for each annular material collection groove 3. The scraper 27 is inserted into the corresponding annular material collection groove 3.

[0030] The motor 15, in conjunction with the first gear 16 and the second gear 17, can drive the rotating arm 26 to rotate, thereby causing the scraper 27 to move in a ring within the annular receiving trough 3 to scrape the wall and push the material, thus facilitating the discharge of the graded Ganoderma lucidum spore powder from the discharge pipe 13.

[0031] A wind-breaking cone 19 is suspended below the filling hopper 12 by a hanger 18. The wind-breaking cone 19 is inserted into the horn mouth 9 and is compatible with the horn mouth 9.

[0032] The air-breaking cone 19 and the horn mouth 9 form an annular air outlet gap. At the same time, the motor 15, in conjunction with the first gear 16 and the second gear 17, can drive the air intake pipe 5 to rotate, thereby making the umbrella-shaped airflow more uniform.

[0033] The top edge of the filling hopper 12 is provided with a filling port 20, and a cover 21 is threaded onto the filling port 20.

[0034] The filling port 20 of the filling hopper 12 is closed by the cover 21, and the airflow blown out by the horn 9 is deflected by the air-breaking cone 19, thereby avoiding backflow.

[0035] A vertical shaft 22 is movably connected through the middle of the filling hopper 12, and a sealing plug 23 that is adapted to the discharge port of the filling hopper 12 is fixedly connected to the bottom end of the vertical shaft 22.

[0036] A handle 24 is fixedly connected to the top of the vertical shaft 22, and a toggle blade 25 is fixedly connected to the edge of the sealing plug 23.

[0037] Setting a sealing plug 23 inside the feeding hopper 12 can prevent Ganoderma lucidum spore powder from falling directly during feeding. At the same time, the rotation of the leaf 25 can easily disturb the Ganoderma lucidum spore powder inside the feeding hopper 12, making it easier to discharge.

[0038] The annular receiving troughs 3 are arranged concentrically, and each annular receiving trough 3 is provided with a guide ramp 4 at its top.

[0039] By setting up the feeding ramp 4, the Ganoderma lucidum spore powder falling on it is guided to the adjacent annular receiving trough 3.

[0040] The working principle of this utility model is as follows:

[0041] In use, first open the cover 21 and add Ganoderma lucidum spore powder into the filling hopper 12 through the filling port 20. Then close the cover 21. At this time, start the blower 8. The blower 8 blows air into the air inlet pipe 5 through the connecting pipe 7 and the rotating pipe joint 6, and finally blows it out through the horn 9. The blown air is distributed in an umbrella shape and passes through the arc-shaped dust filter screen 10 and is discharged through the air outlet 11. At this time, start the motor 15. The motor 15 drives the first gear 16 to rotate. The first gear 16 drives the air inlet pipe 5 through the second gear 17. The vertical shaft 22 is lifted and rotated by the handle 24. At this time, the sealing plug 23 is separated from the outlet of the feeding hopper 12, and the Ganoderma lucidum spore powder inside the feeding hopper 12 is agitated by the agitator blade 25. The Ganoderma lucidum spore powder falls and is classified by the airflow into different annular collection troughs 3. At this time, the air inlet pipe 5 rotates, and the inner wall of the annular collection trough 3 is cleaned by the rotating arm 26 and the scraper 27, and the classified Ganoderma lucidum spore powder is pushed to the discharge pipe 13 and discharged into the collection tank 14 for collection.

[0042] Although the present invention 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 invention should be included within the protection scope of the present invention.
