Description
Technical Field
[0001] This utility model relates to the field of traditional Chinese medicine processing, and in particular to a frequency conversion air separator for processing Astragalus membranaceus. Background Technology
[0002] Astragalus is a commonly used traditional Chinese medicine with effects such as tonifying qi and strengthening the exterior, and promoting diuresis and reducing swelling. In the processing of astragalus, air separation is a crucial step, used to separate impurities and astragalus granules of different qualities. Traditional air separators typically use a fixed wind speed, which cannot be flexibly adjusted according to the size and weight of the astragalus granules, resulting in unsatisfactory separation effects. Furthermore, the air-separated astragalus granules directly enter the collection chamber, lacking a multi-stage screening mechanism, making further separation of astragalus granules of different qualities impossible.
[0003] Based on this, we propose a variable frequency air separator for processing Astragalus membranaceus. Utility Model Content
[0004] To address the technical problems of fixed wind speed and lack of multi-stage screening mechanism in existing Astragalus air separators, this utility model provides a variable frequency air separator for Astragalus processing.
[0005] This utility model is achieved by the following technical solution: a variable frequency air separator for processing Astragalus membranaceus, including a machine body, the machine body including an air separator and a screener, the air separator being installed on a support platform, wherein the air separator includes an air separator chamber, a feeding channel is connected to the top of the air separator chamber, a blower motor is connected to the outside of the air separator chamber, and an air separator pipe is connected to the surface of the air separator chamber, the air separator pipe being positioned corresponding to the screener.
[0006] A drive motor is installed at the top of the air separation chamber, and a drive rod is connected below the drive motor. The bottom end of the drive rod extends outward into the air separation chamber and is connected to a stirring rod.
[0007] The screener includes a screening dish with sieve holes on the bottom surface. The screening dish is installed at an angle, and a feeding plate is connected to the bottom of the screening dish. The feeding plate is arc-shaped.
[0008] The reciprocating vibrating screen mechanism includes:
[0009] The working motor is mounted on the support platform;
[0010] The drive disc is connected to the top of the output shaft of the working motor;
[0011] The bottom end of the moving rod is connected to the edge of the drive disc, and the top end of the moving rod is connected to the reciprocating rod.
[0012] A sliding limit bracket, the bottom end of which is mounted on the upper surface of the support platform;
[0013] A sliding limit groove is formed on the surface of the sliding limit frame. A reciprocating rod is inserted into the sliding limit groove and slides up and down. The top of the reciprocating rod is connected to the screening dish.
[0014] After being air-separated, the Astragalus membranaceus enters the screening dish on the screener through the air separation pipe. Through the operation of the reciprocating vibrating screen mechanism, the working motor drives the drive disc to rotate, which in turn drives the connected moving rod to rotate. The moving rod reciprocates, which in turn drives the reciprocating rod to reciprocate up and down. The reciprocating rod slides inside the limiting sliding groove, and the reciprocating rod drives the screening dish to vibrate back and forth. Through the vibration of the screening dish driven by the reciprocating vibrating screen mechanism, the Astragalus membranaceus is evenly distributed and screened through the sieve holes.
[0015] As a further optimization of this utility model, the screener is provided with at least three sets, and the sieve apertures in the screening dishes of the three sets of screeners decrease in size in sequence. The screening dish at the front end corresponds to the position of the air separator. The outlet of the air separator pipe is located above the screening dish. The feeding plate on the front screening dish overlaps on the rear screening dish, and the feeding plate on the end screening dish overlaps on the storage bin.
[0016] As a further optimization of this utility model, Astragalus enters the air separation chamber through the feeding channel. The blower motor adjusts the wind speed through frequency conversion and performs air separation according to the size and weight of Astragalus. At the same time, the drive motor works, driving the drive rod connected to it to rotate. The drive rod drives the stirring rod connected to it to rotate synchronously. The continuous stirring of the stirring rod prevents the Astragalus from clogging in the air separation chamber.
[0017] As a further optimization of this utility model, a collection dish is provided directly below the screening dish, and an installation rod is fixedly connected to the bottom of the collection dish. A caster wheel is connected to the bottom of the installation rod, and the caster wheel facilitates the transfer of the screening dish.
[0018] As a further optimization of this utility model, the pore size of the screening dish in the multi-stage screener decreases sequentially, which can further separate Astragalus membranaceus of different sizes. Astragalus membranaceus of different sizes falls into the corresponding collection dish below, realizing the collection of Astragalus membranaceus of different sizes. Finally, the remaining Astragalus membranaceus enters the storage chamber through the feeding plate.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

At the same time, the drive motor works, which drives the drive rod connected to it to rotate. The drive rod drives the stirring rod connected to it to rotate synchronously. The continuous stirring of the stirring rod prevents the Astragalus membranaceus from clogging in the air separation chamber.
[0021] 2. This invention utilizes a reciprocating vibrating sieve mechanism to drive the vibration of the screening dish, ensuring that Astragalus membranaceus is evenly distributed and sieved through the sieve holes. Astragalus membranaceus of different sizes falls into the corresponding collection dish below, achieving the collection of Astragalus membranaceus of different sizes. Attached Figure Description

The machine body 1 includes an air separator 2 and a screener 3. The air separator 2 is installed on a support platform 28. The air separator 2 includes an air separation chamber 21. A feeding channel 22 is connected to the upper part of the air separation chamber 21. A blower motor 23 is connected to the outer side of the air separation chamber 21. An air separation pipe 24 is connected to the surface of the air separation chamber 21. The air separation pipe 24 corresponds to the position of the screener 3.
[0032] A drive motor 25 is installed at the top of the air separation chamber 21, and a drive rod 26 is connected below the drive motor 25. The bottom end of the drive rod 26 extends outward into the air separation chamber 21 and is connected to a stirring rod 27.
[0033] More specifically, Astragalus enters the air separation chamber 21 through the feeding channel 22. The blower motor 23 adjusts the wind speed through frequency conversion and performs air separation according to the size and weight of Astragalus. At the same time, the drive motor 25 works, which drives the drive rod 26 connected to it to rotate. The drive rod 26 drives the stirring rod 27 connected to it to rotate synchronously. The continuous stirring of the stirring rod 27 prevents the Astragalus from getting blocked in the air separation chamber 21.
[0034] The screener 3 includes a screening dish 31 with a sieve hole 32 on the bottom surface. The screening dish 31 is installed at an angle and a feeding plate 33 is connected to the bottom of the screening dish 31. The feeding plate 33 is arc-shaped and the screening dish 31 is placed on the support platform 28.
[0035] It should be noted that there are at least three sets of screeners 3. The aperture of the sieve holes 32 in the screening dish 31 of the three sets of screeners 3 decreases in size in sequence. The screening dish 31 at the front corresponds to the position of the air separator 2. The outlet of the air separator pipe 24 in the air separator 2 is located above the screening dish 31. The feeding plate 33 on the front screening dish 31 overlaps on the rear screening dish 31. The feeding plate 33 on the screening dish 31 at the end overlaps on the storage bin 8.
[0036] Both sides of the screening dish 31 are equipped with a reciprocating vibrating screening mechanism 4;
[0037] The reciprocating vibrating screen mechanism 4 includes:
[0038] The working motor 41 is mounted on the support platform 28.
[0039] Drive disk 42 is connected to the top of the output shaft of working motor 41;
[0040] The bottom end of the moving rod 43 is connected to the edge of the drive disc 42, and the top end of the moving rod 43 is connected to the reciprocating rod 44.
[0041] The bottom end of the sliding limit bracket 45 is installed on the upper surface of the support platform 28;
[0042] A sliding limiting groove 46 is formed on the surface of a sliding limiting frame 45. A reciprocating rod 44 is inserted into the sliding limiting groove 46 and slides up and down. The top end of the reciprocating rod 44 is connected to the screening dish 31.
[0043] More specifically, the astragalus in the air separation chamber 21, after air separation, enters the screening dish 31 on the screener 3 through the air separation pipe 24. Through the operation of the reciprocating vibrating screen mechanism 4, the working motor 41 drives the drive disk 42 to rotate, the drive disk 42 drives the connected moving rod 43 to rotate, the moving rod 43 reciprocates, and then drives the reciprocating rod 44 to reciprocate up and down. The reciprocating rod 44 slides inside the limiting sliding groove 46, and the reciprocating rod 44 drives the screening dish 31 to vibrate back and forth. Through the vibration of the screening dish 31 driven by the reciprocating vibrating screen mechanism 4, the astragalus is evenly distributed and screened through the sieve holes 32.
[0044] A collection dish 5 is located directly below the screening dish 31. A mounting rod 6 is fixedly connected to the bottom of the collection dish 5, and a caster wheel 7 is connected to the bottom of the mounting rod 6.
[0045] Specifically, the pore size of the screening dish 31 in the multi-stage screener 3 decreases sequentially, which can further separate Astragalus membranaceus of different sizes. Astragalus membranaceus of different sizes falls into the corresponding collection dish 5 below it, realizing the collection of Astragalus membranaceus of different sizes. Finally, the remaining Astragalus membranaceus enters the storage chamber 8 through the feed plate 33.
[0046] Specific implementation steps of this utility model:
[0047] In use, Astragalus enters the air separation chamber 21 through the feeding channel 22. The blower motor 23 adjusts the wind speed through frequency conversion and performs air separation according to the size and weight of Astragalus. At the same time, the drive motor 25 works, which drives the drive rod 26 connected to it to rotate. The drive rod 26 drives the stirring rod 27 connected to it to rotate synchronously. The continuous stirring of the stirring rod 27 prevents the Astragalus from getting blocked in the air separation chamber 21.
[0048] After being air-separated, the Astragalus membranaceus in the air separation chamber 21 enters the screening dish 31 on the screener 3 through the air separation pipe 24. Through the operation of the reciprocating vibrating screen mechanism 4, the working motor 41 drives the drive disc 42 to rotate, and the drive disc 42 drives the connected moving rod 43 to rotate. The moving rod 43 reciprocates, and then drives the reciprocating rod 44 to reciprocate up and down. The reciprocating rod 44 slides inside the limiting sliding groove 46, and the reciprocating rod 44 drives the screening dish 31 to vibrate back and forth. Through the vibration of the screening dish 31 driven by the reciprocating vibrating screen mechanism 4, the Astragalus membranaceus is evenly distributed and screened through the sieve holes 32.
[0049] The pore size of the screening dish 31 in the multi-stage screener 3 decreases sequentially, which can further separate Astragalus membranaceus of different sizes. Astragalus membranaceus of different sizes falls into the corresponding collection dish 5 below it, realizing the collection of Astragalus membranaceus of different sizes. Finally, the remaining Astragalus membranaceus enters the storage chamber 8 through the feed plate 33.
