Description

Technical Field

[0001] This invention relates to the field of airflow mixing technology, specifically to an airflow mixing device for an airflow circulation system. Background Technology

[0002] In airflow circulation systems, material mixing is a common and critical process. Traditional airflow mixing equipment has several shortcomings: some equipment relies solely on the natural flow of air to mix materials, lacking effective mechanical agitation components, resulting in uneven mixing of materials and airflow, making it difficult to achieve the desired mixing degree and affecting subsequent processes. During the material discharge stage, due to the inherent characteristics of the materials (such as viscosity and agglomeration) and unreasonable equipment discharge structure design, materials easily accumulate in the discharge channel, causing blockages. This not only reduces production efficiency but may also damage the equipment and increase maintenance costs. Furthermore, traditional equipment often only mixes and discharges materials of specific types or states, exhibiting poor adaptability to different types and physical properties, and failing to meet diverse production needs. Summary of the Invention

[0003] To solve the above technical problems, the present invention is achieved through the following technical solution: an airflow mixing device for an airflow circulation system, comprising: a support frame, an air mixing tank fixedly installed inside the support frame, a guide pipe fixedly installed on one side of the outer surface of the air mixing tank, an air supply chamber fixedly installed on the top of the air mixing tank, and an induced draft fan connected to the outer surface of the air supply chamber through a pipe; A mixing component for mixing materials and airflow within a gas mixing tank, the mixing component being fixedly installed at the bottom of the gas mixing tank; The discharge component, used for conveying the mixed material, has a motor fixedly mounted on its outer surface and is fixedly installed at the bottom of the mixing component. Before using the airflow mixing equipment to mix the material, the operator checks all components, such as the air mixing tank, mixing component, discharge component, blower, and motor, to ensure they are securely installed and functioning properly. Ensure the air tank and air guide ring are properly connected via a flexible metal hose, and that sufficient gas pressure is available. Then, the operator adds the material to be mixed into the air mixing tank through the feed pipe. The blower is then started, and air is pumped into the air chamber through the pipe, entering the air mixing tank and initially contacting the material. Powdered materials are conveyed to the air-mixing tank via pneumatic conveying. The pneumatic conveying initially disperses the mixture, making the materials loose. Then, it passes through the mixing components below the air-mixing tank for fine mixing. The finely mixed material is sampled by an automatic sampler on the discharge pipe to test its pass rate. If the test is qualified, it enters the next process through the valve below the discharge pipe. If the test is unqualified, it is switched to another pneumatic conveying channel installed on the outside of the discharge pipe by a flap valve and re-enters the air-mixing tank. This process is the key to fine mixing. Through re-conveying, the finely mixed material is dispersed again. The unorganized and irregular flow of air causes the unqualified material to be dispersed and mixed again irregularly. This cycle is repeated to achieve fine mixing of the material. At the same time, the system has the function of adding materials and mixing again in the middle. The system is controlled by PLC to achieve fully unmanned operation. Under the condition that conditions permit, it can mix multiple times and can also separate the extremely fine materials generated during the mixing process to ensure uniform particle size distribution of the product.

[0004] The mixing assembly includes a tapered conduit with a guide cone fixedly installed in the middle of its interior. Limiting blocks are fixedly installed on both sides of the outer surface of the tapered conduit. A gas guide ring is located below the limiting blocks. A connecting pipe is fixedly installed at the bottom of the tapered conduit, and an airflow mixing head is fixedly installed on the surface of the connecting pipe. Gas from the gas storage tank enters the gas guide ring through a metal flexible hose and is then delivered to the airflow mixing head via a gas delivery pipe.

[0005] Preferably, the conical conduit is fixedly installed at the bottom of the gas mixing tank, the gas guide ring pipe is fixedly connected to the gas mixing tank, and the gas guide ring pipe is fixedly installed at the top of the gas flow mixing head. The gas guide ring pipe is fixedly connected to the gas storage tank through a metal flexible hose.

[0006] Preferably, the airflow mixing head includes a hydraulic press, with an air delivery pipe running through its interior. A mounting base is driven onto the top of the hydraulic press, and an internal threaded tube is threaded onto the mounting base. An air jet pipe is fixedly mounted on the top of the internal threaded tube, and an air disc is fitted onto the top of the air jet pipe. When the hydraulic press operates, it drives the mounting base to move via a transmission mechanism. Since the mounting base extends through the connecting pipe into the interior of the tapered conical guide tube, and the air disc is fitted onto the top of the air jet pipe and movably mounted on the side of the bottom of the tapered conical guide tube, the movement of the mounting base causes the air disc to perform corresponding actions, such as oscillation or vibration. When the airflow from the storage tank enters the air jet pipe through the air delivery pipe, the airflow impacts the air disc, causing it to move at the bottom side of the tapered conical guide tube. Because the air disc is made of wear-resistant silicone, changes in air pressure cause high-frequency vibrations at the edge of the air disc, directly acting on the material and breaking up arches or agglomerates.

[0007] Preferably, the air delivery pipe extends through the air guide ring into its cavity, the hydraulic press is fixedly connected to the connecting pipe, the mounting base extends through the connecting pipe into the interior of the conical guide tube, and the air disc is movably installed on the side of the bottom of the conical guide tube. Simultaneously with the operation of the air disc, the gas ejected from the jet pipe impacts the material at a certain pressure and angle. Under the combined action of the mechanical disturbance of the air disc and the impact force of the gas, the arch-like accumulation structure formed by the material at the bottom of the conical guide tube is broken, and the friction and adhesion between the material particles are weakened, allowing them to fall smoothly and achieving a flow-aiding effect. At the same time, gas is ejected from the jet pipe, and within the conical guide tube, with the guidance of the guide cone, the airflow and material are fully mixed and agitated, achieving uniform mixing of the material and airflow. During the continuous mixing and discharge of the material, the air disc maintains the aforementioned operation and jetting state, continuously breaking up and aiding the flow of the material, ensuring smooth flow of the material within the conical guide tube, and preventing material accumulation from affecting the mixing and discharge effect.

[0008] Preferably, the air disc is made of wear-resistant silicone material, the air disc is frictionally adapted to the material, and the air discs are evenly arranged in a circumferential shape below the guide cone.

[0009] Preferably, the discharge assembly includes a discharge pipe, a stirring chamber fixedly installed at the bottom of the discharge pipe, a T-junction fixedly installed at the bottom of the stirring chamber, mounting brackets fixedly installed on both sides of the outer surface of the stirring chamber, a drive shaft fixedly installed on the outer surface of the mounting brackets, and an anti-clogging device rotatably installed at the center of the drive shaft. After the mixing assembly completes the uniform mixing of the material and the airflow, the mixed material smoothly enters the discharge pipe of the discharge assembly through the connecting pipe, and then the discharge pipe guides the material into the stirring chamber. The operator starts the motor in advance, and the output end of the motor drives the drive shaft to start rotating. Since the drive shaft is fixedly connected to the anti-clogging device, the anti-clogging device also rotates inside the stirring chamber as the drive shaft rotates.

[0010] Preferably, the discharge pipe is fixedly installed at the bottom of the connecting pipe, the drive shaft is fixedly connected to the output end of the motor, and the anti-blocking device is rotatably installed inside the stirring chamber via the drive shaft.

[0011] Preferably, the anti-clogging component includes two positioning bushings. A shaft is rotatably mounted between the opposing surfaces of the two positioning bushings. A collar is fitted onto the surface of the shaft, and a connecting frame is fixedly mounted on the outer surface of the collar. A deflector plate, configured as a triangular folded plate structure, is fixedly mounted on the outer surface of the connecting frame. During rotation, the deflector plate and other components of the anti-clogging component agitate the material within the agitation chamber, keeping the material in a flowing state and effectively preventing material accumulation and blockage within the agitation chamber. After being processed by the anti-clogging component, the material smoothly passes through the agitation chamber and is ultimately guided to the designated subsequent processing equipment or storage location via a three-way pipe.

[0012] Preferably, the positioning bushing is fixedly installed on the outer surface of the mounting frame, the shaft is fixedly connected to the drive shaft, and the shaft drive shaft is rotatably installed inside the agitation chamber.

[0013] Preferably, two collars are provided, and the two collars are symmetrically arranged with the shaft as the center. The actuating plate, the connecting frame and the collars are adapted to the material through friction with the shaft.

[0014] This invention provides an airflow mixing device for an airflow circulation system. It has the following beneficial effects: I. The airflow circulation system's airflow mixing equipment uses a guide cone in the mixing component to guide the material flow, while air discs, in conjunction with the ejected airflow, mix and agitate the material from multiple directions. This ensures thorough and uniform mixing of the material and airflow, improving mixing uniformity and efficiency. The air discs are made of wear-resistant silicone material, which is friction-compatible with the material, ensuring mixing effectiveness while reducing wear and extending service life.

[0015] 2. In the airflow mixing equipment of the airflow circulation system, when the airflow in the air storage tank enters the jet pipe through the air delivery pipe, the airflow blows and causes the air disc to move at the bottom edge of the conical guide tube. Since the air disc is made of wear-resistant silicone material, the change in air pressure causes the edge of the air disc to generate high-frequency vibration, which directly acts on the material, breaking the arch or agglomeration.

[0016] III. The airflow mixing device in this airflow circulation system utilizes an air disc that, while activating, ejects gas from a jet pipe that impacts the material at a specific pressure and angle. Under the combined effect of the air disc's mechanical agitation and the gas's impact force, the arch-like accumulation structure formed by the material at the bottom of the conical guide tube is broken, weakening the friction and adhesion between material particles, allowing them to fall smoothly and achieving a flow-aiding effect. Simultaneously, gas ejected from the jet pipe, within the conical guide tube, works in conjunction with the guiding action of the guide cone to fully mix and agitate the airflow and material, achieving uniform mixing. During the continuous mixing and discharge of the material, the air disc maintains the aforementioned actions and jetting state, continuously breaking up and aiding the flow of the material, ensuring smooth flow within the conical guide tube and preventing material accumulation that could affect the mixing and discharge effect.

[0017] IV. The airflow mixing equipment of this airflow circulation system uses a triangular folded plate structure for the anti-blocking agitator. When rotating, it can generate a good agitation effect on the material, which can effectively deal with materials that are prone to caking or have high viscosity and are prone to blockage. This ensures that the material flows continuously in the mixing chamber, avoids blockage, and ensures continuous and stable operation of the equipment.

[0018] V. The airflow mixing equipment in this airflow circulation system uses components such as the anti-clogging deflector to agitate the material within the mixing chamber during rotation, keeping the material in a flowing state and effectively preventing material accumulation and blockage within the mixing chamber. Furthermore, the anti-clogging deflector can adapt to the discharge requirements of different types and states of materials. Whether granular, powdery, or mixed, the material can be smoothly discharged thanks to the anti-clogging deflector, demonstrating strong applicability and usability in various airflow mixing scenarios. After being processed by the anti-clogging deflector, the material smoothly passes through the mixing chamber and is ultimately guided to the designated subsequent processing equipment or storage location via a three-way pipe.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] First embodiment, such as Figures 1 to 2 As shown, the present invention provides a technical solution: an airflow mixing device for an airflow circulation system, comprising: a support frame 3, an air mixing tank 2 fixedly installed inside the support frame 3, a guide pipe 5 fixedly installed on one side of the outer surface of the air mixing tank 2, an air supply chamber 1 fixedly installed on the top of the air mixing tank 2, and an induced draft fan connected to the outer surface of the air supply chamber 1 through a pipe. Mixing component 6, which is used to mix the material and the airflow in the gas mixing tank 2, is fixedly installed at the bottom of the gas mixing tank 2; Discharge component 7 is used for conveying the mixed material. A motor 4 is fixedly mounted on the outer surface of discharge component 7, which is also fixedly installed at the bottom of mixing component 6. Before using the airflow mixing equipment to mix the material, the operator checks all components, such as the air mixing tank 2, mixing component 6, discharge component 7, blower, and motor 4, to ensure they are securely installed and functioning properly. Ensure the air tank and air guide ring pipe 62 are properly connected via a flexible metal hose, and that sufficient gas pressure is available. Then, the operator adds the material to be mixed into the air mixing tank 2 through the material guide pipe 5. The blower is started, and air is delivered to the air supply chamber 1 through the pipe. The airflow enters the air mixing tank 2 and initially contacts the material. Powdered materials are conveyed to the air mixing tank 2 via pneumatic conveying. The pneumatic conveying initially disperses the mixture, making the materials loose. Then, it is finely mixed by the mixing component 6 below the air mixing tank 2. The finely mixed material is sampled and tested for pass rate by an automatic sampler on the discharge pipe 73. If the test is qualified, it enters the next process through the valve below the discharge pipe 73. If the test is unqualified, it is switched to another pneumatic conveying channel installed outside the discharge pipe 73 by a flap valve and re-enters the air mixing tank 2. This process is the key to fine mixing. Through re-conveying, the finely mixed material is dispersed again. Through the unorganized and irregular flow of air, the unqualified material is dispersed and mixed again irregularly. This cycle is repeated to achieve fine mixing of materials. At the same time, the system has the function of adding materials and mixing again in the middle. The system is controlled by PLC to achieve fully unmanned operation. Under the condition that conditions permit, it has the possibility of multiple mixing. It can also separate the extremely fine materials generated during the mixing process to ensure uniform particle size distribution of the product.

[0023] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 3 to 8 As shown, the mixing component 6 includes a tapered conduit 61. A guide cone 66 is fixedly installed in the middle of the interior of the tapered conduit 61. Limiting blocks 65 are fixedly installed on both sides of the outer surface of the tapered conduit 61. A gas guide ring pipe 62 is provided below the limiting blocks 65. A connecting pipe 63 is fixedly installed at the bottom of the tapered conduit 61. An airflow mixing head 64 is fixedly installed on the surface of the connecting pipe 63. Gas in the gas storage tank enters the gas guide ring pipe 62 through a metal flexible hose, and is then transported to the airflow mixing head 64 through the gas delivery pipe 642.

[0024] The conical conduit 61 is fixedly installed at the bottom of the gas mixing tank 2, the gas guide ring pipe 62 is fixedly connected to the gas mixing tank 2, and the gas guide ring pipe 62 is fixedly installed at the top of the gas flow mixing head 64. The gas guide ring pipe 62 is fixedly connected to the gas storage tank through a metal hose.

[0025] The airflow mixing head 64 includes a hydraulic press 641, with an air supply pipe 642 passing through its interior. A mounting base 644 is driven to the top of the hydraulic press 641, and an internal threaded tube 645 is threaded into the mounting base 644. An air jet pipe 646 is fixedly mounted on the top of the internal threaded tube 645, and an air disc 643 is fitted onto the top of the air jet pipe 646. When the hydraulic press 641 operates, it drives the mounting base 644 to move via a transmission mechanism. Since the mounting base 644 extends through the connecting pipe 63 into the interior of the tapered conical guide tube 61, and the air disc 643 is fitted onto the top of the air jet pipe 646 and movably mounted on the side of the bottom of the tapered conical guide tube 61, the movement of the mounting base 644 causes the air disc to produce corresponding actions, such as oscillation or vibration. When the airflow in the gas storage tank enters the jet pipe 646 through the air delivery pipe 642, the airflow blows and causes the air disc 643 to move at the bottom edge of the conical guide tube 61. Since the air disc 643 is made of wear-resistant silicone material, the change in air pressure causes the edge of the air disc to vibrate at a high frequency, which directly acts on the material, breaking the arch or agglomeration.

[0026] The air supply pipe 642 extends through the air guide ring pipe 62 into its cavity. The hydraulic press 641 is fixedly connected to the connecting pipe 63. The mounting base 644 extends through the connecting pipe 63 into the interior of the conical guide tube 61. The air disc 643 is movably installed on the side of the bottom of the conical guide tube 61. Simultaneously, the air disc is activated, and the gas ejected from the jet pipe 646 impacts the material at a certain pressure and angle. Under the combined action of the mechanical disturbance of the air disc and the impact force of the gas, the arch-shaped accumulation structure formed by the material at the bottom of the conical guide tube 61 is broken, and the friction and adhesion between the material particles are weakened, allowing them to fall smoothly and achieving a flow-aiding effect. At the same time, gas is ejected from the jet pipe 646 and, within the conical guide tube 61, with the guidance of the guide cone 66, the airflow and material are fully mixed and agitated, achieving uniform mixing of the material and the airflow. During the continuous mixing and discharge of the material, the air disc maintains the aforementioned action and jetting state, continuously breaking up and aiding the flow of the material, ensuring smooth flow of the material within the conical guide tube 61, and preventing material accumulation from affecting the mixing and discharge effect.

[0027] The air disc 643 is made of wear-resistant silicone material. The air disc 643 is adapted to friction with the material, and the air disc 643 is evenly arranged in a circumferential shape below the guide cone 66.

[0028] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 9 to 12As shown, the discharge assembly 7 includes a discharge pipe 73, with a stirring chamber 71 fixedly installed at the bottom of the discharge pipe 73. A three-way pipe 74 is fixedly installed at the bottom of the stirring chamber 71. Mounting brackets 76 are fixedly installed on both sides of the outer surface of the stirring chamber 71, and a drive shaft 72 is fixedly installed on the outer surface of the mounting brackets 76. An anti-blocking device 75 is rotatably installed at the axis of the drive shaft 72. After the mixing assembly 6 completes the uniform mixing of the material and the airflow, the mixed material smoothly enters the discharge pipe 73 of the discharge assembly through the connecting pipe 63, and then the discharge pipe 73 guides the material into the stirring chamber 71. The operator starts the motor 4 in advance, and the output end of the motor 4 drives the drive shaft 72 to start rotating. Since the drive shaft 72 is fixedly connected to the anti-blocking device 75, the anti-blocking device 75 also rotates inside the stirring chamber 71 as the drive shaft 72 rotates.

[0029] The discharge pipe 73 is fixedly installed at the bottom of the connecting pipe 63, the drive shaft 72 is fixedly connected to the output end of the motor 4, and the anti-blocking device 75 is rotatably installed inside the stirring chamber 71 through the drive shaft 72.

[0030] The anti-blocking device 75 includes two positioning bushings 752. A shaft 753 is rotatably mounted between the opposing surfaces of the two positioning bushings 752. A collar 754 is fitted onto the surface of the shaft 753. A connecting frame 755 is fixedly mounted on the outer surface of the collar 754. A deflector 751 is fixedly mounted on the outer surface of the connecting frame 755. The deflector 751 is configured as a triangular folded plate structure. During rotation, the deflector 751 and other components of the anti-blocking device 75 agitate the material in the agitation chamber 71, keeping the material in a flowing state and effectively preventing the material from accumulating and blocking in the agitation chamber 71. After being processed by the anti-blocking device 75, the material smoothly passes through the agitation chamber 71 and is finally guided to the designated subsequent processing equipment or storage location via the three-way pipe 74.

[0031] The positioning bushing 752 is fixedly installed on the outer surface of the mounting bracket 76, the shaft 753 is fixedly connected to the transmission shaft 72, and the shaft 753 and the transmission shaft 72 are rotatably installed inside the stirring chamber 71.

[0032] Two collars 754 are provided, and the two collars 754 are symmetrically arranged with the shaft 753 as the center. The actuating plate 751, the connecting frame 755 and the collars 754 are adapted to the material through friction with the shaft 753.

[0033] Before using the airflow mixing equipment to mix materials, operators should check all components, such as the air mixing tank 2, mixing assembly 6, discharge assembly 7, induced draft fan, and motor 4, to ensure they are securely installed and functioning properly. Ensure the air tank and air guide ring pipe 62 are properly connected via a flexible metal hose, and that sufficient gas pressure is available. Then, operators should add the material to be mixed into the air mixing tank 2 through the material guide pipe 5. Start the induced draft fan; it will then blow air into the air delivery chamber 1 through the pipe, allowing the airflow to enter the air mixing tank 2 and initially contact the material.

[0034] Gas from the storage tank enters the air guide ring pipe 62 through a metal hose, and is then delivered to the airflow mixing head 64 via the air delivery pipe 642. The hydraulic press 641 operates, driving the mounting base 644 to move via a transmission mechanism. Since the mounting base 644 extends through the connecting pipe 63 into the interior of the conical guide pipe 61, and the air disc 643 is fitted onto the top of the jet pipe 646 and movably mounted on the side of the bottom of the conical guide pipe 61, the movement of the mounting base 644 causes the air disc to perform corresponding actions, such as oscillation and vibration. When the airflow from the storage tank enters the jet pipe 646 through the air delivery pipe 642, the airflow impacts the air disc 643, causing it to move on the side of the bottom of the conical guide pipe 61. Because the air disc 643 is made of wear-resistant silicone, changes in air pressure cause high-frequency vibrations at the edge of the air disc, directly acting on the material and breaking up arches or agglomerates.

[0035] Under the combined action of the mechanical disturbance of the air disc and the impact force of the gas, the arch-shaped accumulation structure of the material at the bottom of the conical guide tube 61 is broken, and the friction and adhesion between the material particles are weakened, allowing them to fall smoothly and achieving a flow-aiding effect. Simultaneously, gas is ejected from the jet pipe 646, and within the conical guide tube 61, in conjunction with the guiding action of the guide cone 66, the airflow and material are thoroughly mixed and agitated, achieving uniform mixing of the material and the airflow. During the continuous mixing and discharge of the material, the air disc maintains the aforementioned actions and jetting state, continuously breaking up and aiding the flow of the material, ensuring smooth flow of the material within the conical guide tube 61, and preventing material accumulation from affecting the mixing and discharge effect.

[0036] After the mixing component 6 completes the uniform mixing of materials and airflow, the mixed materials smoothly enter the discharge pipe 73 of the discharge component through the connecting pipe 63, and then the discharge pipe 73 guides the materials into the stirring chamber 71. The operator starts the motor 4 in advance, and the output end of the motor 4 drives the drive shaft 72 to start rotating. Since the drive shaft 72 is fixedly connected to the anti-blocking device 75, the anti-blocking device 75 also rotates inside the stirring chamber 71 as the drive shaft 72 rotates.

[0037] During rotation, the agitator 751 and other components of the anti-blocking device 75 agitate the material in the agitation chamber 71, keeping the material in a flowing state and effectively preventing the material from accumulating and clogging in the agitation chamber 71. After being processed by the anti-blocking device 75, the material passes smoothly through the agitation chamber 71 and is finally guided to the designated subsequent processing equipment or storage location through the three-way pipe 74.
