Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wind-powered conveyors for mugwort floss, specifically a wind-powered conveying device for mugwort floss. Background Technology
[0002] Moxa floss is a traditional Chinese medicine material made from the dried leaves of the Artemisia argyi plant (a member of the Asteraceae family) through a series of complex processes. Specifically, the leaves undergo repeated sun-drying, pounding, crushing, and sifting to remove impurities and dust, ultimately resulting in a soft, cotton-like substance called moxa floss. Moxa floss is grayish-white in color, soft as down, easily ignited without producing a flame, and has a fragrant aroma, making it ideal for moxibustion. Moxa floss pneumatic conveying devices are typically equipment that uses wind or airflow to transport moxa floss. Such devices may include fans, ducts, conveying pipes, dust removal devices, etc., designed to efficiently transport moxa floss from one location to another while minimizing the carrying of impurities and dust. Pneumatic conveying technology has wide applications in many fields, such as chemical engineering, food processing, and mining. In the field of moxa floss processing, when long-distance, large-volume transportation of moxa floss is required, and the integrity and quality requirements of the moxa floss are not high, pneumatic conveying technology can be used.
[0003] Chinese Patent Publication No. CN107879114A discloses a rice husk pneumatic conveyor, comprising a base, a feeding pipe, a suction motor, a suction motor base, a hopper, a suction pipe, and a suction tube. The feeding pipe, suction motor, suction motor base, hopper, and suction pipe are mounted on the base. The feeding pipe is connected to the air outlet of the suction motor, the air inlet of the suction motor is connected to the suction tube, the suction tube is connected to the hopper, and the hopper outlet is connected to the feeding pipe. This invention, by setting a spiral scraper rod inside the suction tube and using a scraper motor to drive the scraper rod to rotate, can keep the suction tube unobstructed even when transporting damp rice husks, preventing blockages. The scraper motor is sealed with a sealed housing to prevent rice husks from entering the scraper motor. The scraper rod is connected to the scraper motor via a clamp, making disassembly convenient.
[0004] The existing technical solutions described above have the following drawbacks: Moxa wool is very dry and extremely susceptible to moisture. When moxa wool becomes damp, its internal active ingredients may change due to the moisture, leading to a reduction in efficacy. This directly affects the effectiveness of moxa wool in moxibustion and other therapies. Existing pneumatic conveying devices simply blow the moxa wool into the storage chamber using high-pressure air. When the air humidity is high, humid air is also blown into the storage chamber, causing the moxa wool in the storage chamber to become damp. Therefore, we propose a pneumatic conveying device for moxa wool to solve the problems mentioned above. Utility Model Content
[0005] The purpose of this invention is to provide a pneumatic conveying device for moxa wool, in order to solve the problem mentioned in the background art that the existing pneumatic conveying devices only blow moxa wool into the storage chamber using high-pressure air. When the air humidity is high, humid air will also be blown into the storage chamber, causing the moxa wool in the storage chamber to become damp.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic conveying device for moxa wool, comprising a Roots blower, an air heating mechanism installed on one side of the Roots blower, a feeding hopper installed on one side of the air heating mechanism, a storage tank installed on one side of the feeding hopper, and an exhaust box installed on one side above the storage tank. The exhaust box includes an exhaust box shell, a blower plate, a baffle mechanism, a guide plate, a first filter screen, an inner filter barrel, an outer filter barrel, and an exhaust filter plate.
[0007] Preferably, the outer end of the exhaust box is provided with an exhaust box shell, the outer end of the storage tank is provided with a storage tank shell, and the lower end of the exhaust box shell is provided with an induced draft fan plate. The induced draft fan plate has a bottom-large and top-bottom structure, and the storage tank shell and the induced draft fan plate are sealed and fixedly connected.
[0008] Preferably, two baffle mechanisms are installed at the lower end of the exhaust box, with one end of the baffle mechanism near the center of the exhaust box tilting downwards.
[0009] Preferably, a first filter screen is installed above the exhaust box, a guide plate is installed above the first filter screen, the guide plate is fixedly connected to the exhaust box shell, an inner filter barrel is sealed and installed above the exhaust box shell, an outer filter barrel is installed outside the inner filter barrel, the lower end of the outer filter barrel is sealed and fixedly connected to the guide plate, and an exhaust filter plate is provided at the upper end of the exhaust box shell.
[0010] Preferably, the material blocking mechanism includes a central baffle, an upper baffle, and a lower baffle. The upper baffle is equidistantly disposed above the central baffle, and the lower baffle is equidistantly disposed below the central baffle. One end of the upper baffle and the lower baffle is fixedly connected to the central baffle, and one end of the upper baffle and the lower baffle is inclined downward.
[0011] Preferably, an air supply pipe is sealed between the outlet end of the Roots blower and the inlet end of the air heating mechanism; a feeding check valve is sealed below the feeding hopper; a three-way pipe is sealed below the feeding check valve; the outlet end of the air heating mechanism and one end of the three-way pipe are sealed together by an air inlet pipe; a feeding box is fixedly installed at one end of the storage tank; and the other end of the three-way pipe is sealed together with the feeding box by a feeding pipe.
[0012] Preferably, the air heating mechanism includes a junction box, a heating chamber, a first heating element, a second heating element, and a thermometer. The junction box is fixedly installed at the upper end of the air heating mechanism. A heating chamber is provided inside the air heating mechanism. The first heating element and the second heating element are arranged at intervals inside the air heating mechanism. The first heating element and the second heating element are staggered. A thermometer is installed at the middle position of the upper end inside the heating chamber.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model heats air by setting up an air heating mechanism. The junction box of the air heating mechanism powers and heats the second heating element, which is spaced and staggered, with the first heating element. A thermometer monitors the temperature in real time. After the air heating mechanism has preheated, the feeding check valve and the Roots blower are turned on. The turned-on Roots blower compresses the air and blows it into the air delivery pipe. The air delivery pipe guides the air into the air heating mechanism, where it is heated by the first and second heating elements. The heated air is then blown into the three-way pipe through the air inlet pipe. The air pressure difference draws the moxa wool from the feeding hopper into the delivery pipe. The heated air not only reduces the humidity in the air but also dries the moxa wool, reducing the impact of moisture absorbed by the moxa wool itself. This solves the problem of existing pneumatic conveying devices that only blow moxa wool into the storage chamber with high-pressure air, which can also blow humid air into the storage chamber when the air humidity is high, causing the moxa wool in the storage chamber to become damp.
[0015] 2. In this utility model, the moxa wool flows into the feeding box and towards the exhaust box along with the airflow. The moxa wool first comes into contact with the lower baffle mechanism, and the lower baffle at the bottom of the baffle mechanism blocks the moxa wool. Due to gravity, the moxa wool falls into the storage tank. Some air flows to the top of the central baffle due to its inclination, and is blocked again by the upper baffle, thus causing some moxa wool to be blocked and fall into the storage tank along the arc of the baffle mechanism. It then comes into contact with the upper baffle mechanism again, and is blocked again, falling into the storage tank along the arc of the baffle mechanism. This reduces the impact of the pressure of the airflow on the first filter screen, which affects the filtration efficiency. The moxa wool is filtered by the first filter screen, and some of it is filtered above the first filter screen. The moxa wool comes into contact with the inner filter barrel and is filtered by the inner filter barrel, remaining inside the inner filter barrel. Finally, the moxa wool comes into contact with the outer filter barrel and is filtered by the outer filter barrel, remaining inside the outer filter barrel. The air after passing through the outer filter barrel is discharged after passing through the exhaust filter plate. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Please see Figure 1-4 One embodiment of this utility model is a pneumatic conveying device for moxa wool, comprising a Roots blower 1, an air heating mechanism 3 installed on one side of the Roots blower 1, a feeding hopper 2 installed on one side of the air heating mechanism 3, a storage tank 4 installed on one side of the feeding hopper 2, and an exhaust box 11 installed on one side above the storage tank 4.

[0023] Air is heated by an air heating mechanism 3. The junction box 12 of the air heating mechanism 3 powers the first heating element 14 and the second heating element 15, which are spaced apart and staggered, to heat the air. The thermometer 16 monitors the temperature in real time. After the air heating mechanism 3 has preheated, the feeding check valve 8 and the Roots blower 1 are turned on. The turned-on Roots blower 1 compresses the air and blows it into the air supply pipe 5. The air supply pipe 5 guides the air into the air heating mechanism 3. The air is heated by the first heating element 14 and the second heating element 15. The heated air is blown into the three-way pipe 9 through the air inlet pipe 6. The air flow pressure difference introduces the moxa wool from the feeding hopper 2 into the supply pipe 7. The heated air not only reduces the humidity in the air, but also dries the moxa wool, reducing the impact of the moisture absorbed by the moxa wool itself on the moxa wool.
[0024] Please see Figure 3 The outer end of the exhaust box 11 is provided with an exhaust box shell 18, the outer end of the storage tank 4 is provided with a storage tank shell 17, the lower end of the exhaust box shell 18 is provided with a blower plate 19, the blower plate 19 has a bottom-large and top-bottom structure, the storage tank shell 17 is sealed and fixedly connected to the blower plate 19, and two baffle mechanisms 20 are installed at the lower end inside the exhaust box 11, the end of the baffle mechanism 20 near the center of the exhaust box 11 is inclined downward.
[0025] Please see Figure 3 A first filter screen 22 is installed above the exhaust box 11, and a guide plate 21 is installed above the first filter screen 22. The guide plate 21 is fixedly connected to the exhaust box housing 18. An inner filter barrel 23 is sealed and installed above the exhaust box housing 18. An outer filter barrel 24 is installed outside the inner filter barrel 23. The lower end of the outer filter barrel 24 is sealed and fixedly connected to the guide plate 21. An exhaust filter plate 25 is provided at the upper end of the exhaust box housing 18.
[0026] Please see Figure 4 The material blocking mechanism 20 includes a central baffle 26, an upper baffle 27 and a lower baffle 28. The upper baffle 27 is equidistantly disposed above the central baffle 26, and the lower baffle 28 is equidistantly disposed below the central baffle 26. One end of the upper baffle 27 and the lower baffle 28 is fixedly connected to the central baffle 26, and one end of the upper baffle 27 and the lower baffle 28 is inclined downward.
[0027] Please see Figure 1 An air supply pipe 5 is sealed between the outlet end of the Roots blower 1 and the inlet end of the air heating mechanism 3. A feeding check valve 8 is sealed below the feeding hopper 2. A three-way pipe 9 is sealed below the feeding check valve 8. The outlet end of the air heating mechanism 3 and one end of the three-way pipe 9 are sealed together by an air inlet pipe 6. A feeding box 10 is fixedly installed at one end of the storage tank 4. The other end of the three-way pipe 9 is sealed together with the feeding box 10 by a feeding pipe 7.
[0028] Please see Figure 2 The air heating mechanism 3 includes a junction box 12, a heating chamber 13, a first heating element 14, a second heating element 15, and a thermometer 16. The junction box 12 is fixedly installed at the upper end of the air heating mechanism 3. The heating chamber 13 is provided inside the air heating mechanism 3. The first heating element 14 and the second heating element 15 are arranged at intervals inside the air heating mechanism 3. The first heating element 14 and the second heating element 15 are staggered. The thermometer 16 is installed at the middle position of the upper end inside the heating chamber 13.
[0029] Working principle: In use, first turn on the air heating mechanism 3. The junction box 12 of the air heating mechanism 3 powers the first heating element 14 and the second heating element 15, which are spaced and staggered, to heat it. The thermometer 16 monitors the temperature in real time. After the air heating mechanism 3 has preheated, turn on the feeding check valve 8 and the Roots blower 1. The turned-on Roots blower 1 compresses the air and blows it into the air supply pipe 5. The air supply pipe 5 guides the air into the air heating mechanism 3, where it is heated by the first heating element 14 and the second heating element 15. The heated air is then blown into the three-way pipe 9 through the air inlet pipe 6. The air pressure difference draws the moxa wool from the feeding hopper 2 into the conveying pipe 7. The heated air not only reduces the humidity in the air but also dries the moxa wool, reducing the impact of moisture absorbed by the moxa wool itself. The conveying pipe 7 transports the moxa wool to the feeding box 10. The moxa wool flows with the air into the feeding box 10 and towards the exhaust box 11. The moxa wool first comes into contact with the lower part of the feeding box 10. The baffle mechanism 20 has a lower baffle 28 at its lower end that blocks the moxa wool. Due to gravity, the moxa wool falls into the storage tank 4. Some air flows to the top of the central baffle 26 due to its inclination, and is blocked again by the upper baffle 27. This causes some of the moxa wool to fall into the storage tank 4 along the arc of the baffle mechanism 20. It then comes into contact with the upper baffle mechanism 20 again and is blocked again, falling into the storage tank 4 along the arc of the baffle mechanism 20. This reduces the impact of the pressure of the air flow on the first filter screen 22, which affects the filtration efficiency. The moxa wool is filtered by the first filter screen 22, and is filtered above the first filter screen 22. The moxa wool comes into contact with the inner filter barrel 23 and is filtered by the inner filter barrel 23, where it stays inside. Finally, the moxa wool comes into contact with the outer filter barrel 24 and is filtered by the outer filter barrel 24, where it stays inside. The air that passes through the outer filter barrel 24 is discharged after passing through the exhaust filter plate 25.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
