Description

Technical Field

[0001] This utility model belongs to the field of pneumatic conveying technology, specifically relating to an anti-clogging carbon black pneumatic conveying device. Background Technology

[0002] The anti-clogging carbon black pneumatic conveying device is a material conveying equipment specifically developed for the characteristics of carbon black powder, which can effectively avoid clogging during the conveying process.

[0003] Patent publication number CN216444235U discloses an anti-clogging carbon black pneumatic conveying device, relating to the technical field of pneumatic conveying. The device, a booster-type energy-saving anti-clogging pneumatic conveying device, includes a storage tank. A discharge pipe is fixedly installed at the bottom of the storage tank, and an air supply pipe is fixedly installed at the bottom of the discharge pipe. A high-pressure air tank is fixedly installed on one side of the air supply pipe. The storage tank is equipped with a cover plate, and a motor is fixedly installed at the top of the cover plate. A stirring rod is provided at the bottom of the motor, and the output end of the motor is fixedly connected to the top of the stirring rod. This booster-type energy-saving anti-clogging pneumatic conveying device has a simple structure and is easy to use. It ensures uniform material conveying, minimizes discharge pipe blockage, improves particle conveying efficiency, and minimizes the dispersion of particulate dust through the exhaust pipe, thus preventing environmental impact. It also enhances connectivity, making the filter head easy to install and disassemble, and facilitating replacement and cleaning.

[0004] However, the current anti-clogging pneumatic conveying device for carbon black has the following problems: carbon black powder has the characteristics of high specific surface area and strong agglomeration. When it accumulates in the feed bin, the particles are easily adsorbed and agglomerated by van der Waals forces, forming a stable arch-shaped structure. When the material is discharged by rotating the spiral blades, the force of the spiral blades only acts on the local material near the discharge port and cannot reach the agglomerated material in the middle and upper part of the bin. Therefore, we propose an anti-clogging pneumatic conveying device for carbon black. Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging carbon black pneumatic conveying device that can solve the problem in related technologies where carbon black powder has a high specific surface area and strong agglomeration properties. When it accumulates in the feed hopper, the particles are easily adsorbed and agglomerated by van der Waals forces, forming a stable arch-shaped structure. When the material is discharged by rotating the spiral blades, the force of the spiral blades only acts on the local material near the discharge port and cannot reach the agglomerated material in the upper middle part of the hopper.

[0006] The specific technical solution adopted by this utility model is as follows: A clog-resistant pneumatic conveying device for carbon black includes a high-legged stand and a support frame. The support frame is positioned below the high-legged stand. A feed tank is fixedly installed inside the high-legged stand. A storage tank is fixedly installed on the inner wall of the support frame. A filter cylinder is installed on the top of the storage tank. A conveying pipe is provided between the storage tank and the filter cylinder. A feeding mechanism is provided on the inner wall of the storage tank. The feeding mechanism includes a feed inlet located at the top of the storage tank. A servo motor is fixedly mounted on the top of the storage tank. An eccentric rod is fixedly mounted on the output end of the servo motor. A stirring blade is provided on the circumferential surface of the eccentric rod. A hollow frame is fixedly mounted on the circumferential surface of the eccentric rod. A reciprocating spiral groove is formed on the circumferential surface of the eccentric rod. The hollow frame is threaded onto the circumferential surface of the eccentric rod. A unblocking rod is slidably mounted on the inner wall of the hollow frame. The rotation of the eccentric rod, combined with the reciprocating spiral groove, causes the hollow frame to move up and down reciprocally. The movement of the hollow frame drives the unblocking rod to move.

[0007] A spring seat is provided between the unblocking rod and the hollow frame. The surface of the unblocking rod near the storage tank is set as an inclined surface. The number of unblocking rods is set to three, and they are arranged in a circular array along the center of the hollow frame.

[0008] A connecting rod is fixedly installed at the bottom of the eccentric rod, and an anti-blocking rod is fixedly installed at the bottom of the connecting rod. A conveying plate is provided inside the feed tank, and the material in the feed tank is rotated and discharged through the conveying plate.

[0009] A vacuum pump is installed at the top of the filter cartridge, and a filter is installed on the surface of the vacuum pump.

[0010] The filter cylinder is equipped with a filtration mechanism inside. The filtration mechanism includes a fixed end of a servo motor II, a filter bag at the output end of the servo motor II, and an exhaust pipe on the circumferential surface of the filter cylinder.

[0011] The filter cartridge is fixedly equipped with a sweeping plate, which contacts the filter bag. The output end of the servo motor rotates the filter bag, causing it to rotate. The rotation of the filter bag causes the dust on the inner wall of the filter bag to be swept off by the sweeping plate and then discharged through the discharge pipe.

[0012] The bottom of the sweeping plate is provided with a discharge pipe, and a fixing button is fixedly installed on the inner wall of the filter cylinder. A rubber plate is rotatably installed on the inner wall of the fixing button. A torsion spring is provided between the rubber plate and the fixing button. The torsion spring drives the rubber plate to reset, so that it can adapt to the thickness of the particles in the filter bag and prevent the filter bag from being scratched. The number of fixing buttons and rubber plates is set to three, and they are arranged in a circular array along the center circumference of the filter cylinder.

[0013] The technical effects achieved by this utility model are as follows: This invention utilizes a feeding mechanism to store materials in a feeding tank. During transport, a vacuum pump extracts air, creating a negative pressure environment. Under this negative pressure, the material in the feeding tank is drawn in through the conveying pipe and ultimately transported to a storage tank for collection. The rotation of the eccentric rod breaks up the agglomerated structure of the carbon black, ensuring uniform dispersion of the carbon black particles. This helps ensure that the carbon black enters the pipeline in a more uniform state during subsequent pneumatic conveying, avoiding transport obstructions caused by agglomeration and guaranteeing the continuity of material supply. During the pneumatic conveying of carbon black, local blockages may occur at the outlet of the feeding tank or at the connecting pipe. The reciprocating unblocking rod and anti-blocking rod disperse the blocked carbon black, restoring normal material flow and ensuring the stable operation of the conveying system.

[0014] This invention, through the design of a filtration mechanism, allows dust generated during material transport to enter the filter bag for filtration as the material passes through the conveying pipe. After passing through the filter bag, the dust is discharged through the exhaust pipe. Over long-term use, the filter bag is prone to clogging due to the accumulation of particulate matter. The rotation of the filter bag causes the particulate matter to be swept off by the sweeping plates and then adsorbed and discharged through the discharge pipe. Simultaneously, as the filter bag rotates, its outer wall contacts the rubber plate, sweeping off any attached particulate matter. This prevents the filter bag from clogging due to long-term particle accumulation, ensuring that the filter cartridge maintains a consistently high filtration efficiency. The outer wall of the filter bag intercepts larger particles, while the inner wall retains smaller particles, allowing the dust-laden airflow entering the filter cartridge to be continuously and effectively filtered.

Detailed Implementation

[0017] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0018] like Figure 1-5 As shown, an anti-clogging carbon black pneumatic conveying device includes a high-leg frame 1 and a support frame 3. The support frame 3 is located below the high-leg frame 1. A feed tank 2 is fixedly installed inside the high-leg frame 1. A storage tank 4 is fixedly installed on the inner wall of the support frame 3. A filter cylinder 6 is installed on the top of the storage tank 4. A conveying pipe 5 is provided between the storage tank 4 and the filter cylinder 6. A feeding mechanism 9 is provided on the inner wall of the storage tank 4. The feeding mechanism 9 includes a feed inlet 90, which is located on the top of the storage tank 4. A fixed end of a servo motor 91 is located on the top of the storage tank 4. The output end of the servo motor 91 is fixed. An eccentric rod 92 is installed, with stirring blades on its circumferential surface. A hollow frame 93 is fixedly installed on the circumferential surface of the eccentric rod 92, and a reciprocating spiral groove is opened on the circumferential surface of the eccentric rod 92. The hollow frame 93 is threaded onto the circumferential surface of the eccentric rod 92, and a slidable rod 94 is slidably installed on the inner wall of the hollow frame 93. The rotation of the eccentric rod 92 can break the agglomerated structure of carbon black, so that the carbon black particles are evenly dispersed. This helps to ensure that the carbon black can enter the pipeline in a more uniform state during the subsequent pneumatic conveying process, avoiding the obstruction of conveying caused by agglomeration and ensuring the continuity of material supply.

[0019] A spring seat is provided between the unblocking rod 94 and the hollow frame 93. The surface of the unblocking rod 94 near the storage tank 4 is set as an inclined surface. The number of unblocking rods 94 is set to three, and they are arranged in a circular array along the center circumference of the hollow frame 93.

[0020] A connecting rod 95 is fixedly installed at the bottom of the eccentric rod 92, and an anti-blocking rod 96 is fixedly installed at the bottom of the connecting rod 95. A conveying plate 97 is installed inside the feed tank 2. With the setting of the unblocking rod 94 and the anti-blocking rod 96 moving up and down, the blocked carbon black is broken up, the normal flow of materials is restored, and the stable operation of the conveying system is ensured.

[0021] A vacuum pump 7 is installed on the top of the filter cartridge 6, and a filter 8 is installed on the surface of the vacuum pump 7. The filter 8 is installed on the surface of the vacuum pump 7 to filter the air entering the system and prevent impurities from entering the system.

[0022] A discharge pipe 104 is provided at the bottom of the sweeping plate 103. A fixing button 105 is fixedly installed on the inner wall of the filter cylinder 6. A rubber plate 106 is rotatably installed on the inner wall of the fixing button 105. A torsion spring is provided between the rubber plate 106 and the fixing button 105. The number of fixing buttons 105 and rubber plates 106 is set to three, and they are arranged in a circular array along the center of the filter cylinder 6.

[0023] According to the above structure, the material is stored in the feed tank 2. During conveying, the air in the feed tank 2 is extracted by the vacuum pump 7 to create a negative pressure environment. Under the action of negative pressure, the material in the feed tank 2 is sucked in through the conveying pipe 5. As the material moves in the conveying pipe 5, it is filtered by the filter cartridge 6 to prevent large particles or impurities in the material from entering the vacuum pump 7, thereby protecting the vacuum pump 7. A filter 8 is installed on the surface of the vacuum pump 7 to filter the air entering the system, preventing impurities from entering the system and ensuring the normal operation of the system. The sucked-in material is finally conveyed to the storage tank 4 for collection. Before the material is conveyed in the feed tank 2, the output end of the servo motor 91 rotates to drive the eccentric rod 92 to rotate. The rotation of the eccentric rod 92 drives the stirring blade to rotate, thereby stirring the material in the feed tank 2. Carbon black, due to its own characteristics... Carbon black particles tend to agglomerate in the feed tank 2. The rotation of the eccentric rod 92 can break up the agglomerated structure of the carbon black, making the carbon black particles evenly dispersed. This helps ensure that the carbon black enters the pipeline in a more uniform state during subsequent pneumatic conveying, avoiding conveying obstructions caused by agglomeration and ensuring the continuity of material supply. During the pneumatic conveying of carbon black, local blockages may occur at the outlet of the feed tank 2 or at the connecting pipeline. The rotation of the eccentric rod 92, with the setting of the reciprocating spiral groove, causes the hollow frame 93 to move up and down. The movement of the hollow frame 93 drives the movement of the unblocking rod 94. At the same time, the rotation of the eccentric rod 92 drives the rotation of the connecting rod 95, which in turn drives the rotation of the anti-blocking rod 96. With the setting of the unblocking rod 94 and the anti-blocking rod 96 moving up and down, the blocked carbon black is dispersed, restoring the normal flow of material and ensuring the stable operation of the conveying system.

[0024] like Figure 1-5 As shown, the filter cylinder 6 is equipped with a filter mechanism 10 inside. The filter mechanism 10 includes a fixed end of a servo motor 100, a filter bag 101 at the output end of the servo motor 100, and an exhaust pipe 102 on the circumferential surface of the filter cylinder 6.

[0025] A sweeping plate 103 is fixedly installed inside the filter cartridge 6. The sweeping plate 103 contacts the filter bag 101, causing the particles attached to the surface to be swept off, so that the filter bag 101 will not be blocked due to the accumulation of particles over a long period of time, thereby ensuring that the filter cartridge 6 always maintains a high filtration efficiency. According to the above structure, when the material passes through the conveying pipe 5, the dust generated during the conveying process will enter the filter bag 101 for filtration and be discharged through the exhaust pipe 102 after passing through the filter bag 101. With long-term use, the filter bag 101 is prone to accumulating particulate matter and becoming clogged. At this time, the output end of the servo motor 100 rotates to drive the filter bag 101 to rotate. The rotation of the filter bag 101 causes the dust on the inner wall of the filter bag 101 to be swept off by the sweeping plate 103 and discharged through the discharge pipe 104. At the same time, when the filter bag 101 rotates, its outer wall contacts the rubber plate 106, causing the particulate matter attached to the surface to be swept off, so that the filter bag 101 will not become clogged due to long-term accumulation of particulate matter. This ensures that the filter cartridge 6 always maintains a high filtration efficiency. The outer wall of the filter bag 101 intercepts larger particulate matter, while the inner wall contains smaller particulate matter, so that the dust-laden airflow entering the filter cartridge 6 can be continuously and effectively filtered.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
