Description

Technical Field

[0001] This invention relates to the field of pneumatic conveying equipment technology, and in particular to a silo pump ash removal system. Background Technology

[0002] As a core component of pneumatic conveying systems, silo pumps are widely used in industrial dust removal and material handling. Their main function is to temporarily store collected dust and then transport it to a designated location using high-pressure gas. Traditional silo pump dust removal systems typically include the pump body, feeding assembly, air intake assembly, level gauge assembly, pressure detection assembly, exhaust assembly, fluidization assembly, and discharge pipe fittings. The feeding assembly receives dust, the air intake assembly provides conveying pressure, the fluidization assembly assists in dust fluidization, and finally, the discharge pipe fittings and discharge valve assembly achieve dust discharge and conveying.

[0003] In existing silo pump dust removal systems, anti-clogging measures mostly rely on fluidizing plates installed at the bottom of the pump for jet cleaning. Airflow is introduced into the silo through the fluidizing plates to fluidize the dust at the bottom, improving its flowability. However, in practical applications, due to the mutual compression and adhesion between dust particles, dust tends to compact and agglomerate during temporary storage and transport within the pump, significantly reducing its flowability.

[0004] Relying solely on the upward blowing of the bottom fluidized plate to prevent clogging has significant limitations when dust has already compacted. When the dust is compacted into a dense structure, the airflow from the fluidized plate struggles to penetrate the compacted layer, instead further compressing the dust at the bottom, making it even harder to discharge and severely impacting discharge efficiency. This compaction hinders the normal fall of dust, causing it to accumulate continuously within the silo and further exacerbating discharge difficulties.

[0005] At the same time, airflow in one direction cannot fully disrupt the binding relationship between dust particles and cannot effectively break up agglomerates, which can easily cause large pieces of dust to fall and form blockages in the discharge pipe and subsequent conveying pipelines. This will not only interrupt the conveying process, but may also cause equipment shutdown, increasing maintenance costs and the risk of production interruption. Summary of the Invention

[0006] This invention addresses the shortcomings of existing technologies by providing a silo pump ash removal system. It solves the technical problems of traditional silo pumps relying solely on bottom fluidizing plates for blowing, which easily leads to dust compaction, discharge blockage, and low conveying efficiency. The system achieves efficient dust dispersion, prevents compaction and blockage, and improves the operational stability and reliability of the silo pump ash removal system.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A silo pump dust removal system includes a silo pump and a feeding assembly, an air inlet assembly, a level gauge assembly, a pressure detection assembly, an exhaust assembly, a fluidizing assembly, and a discharge pipe fitting mounted on the silo pump. The discharge pipe fitting is equipped with a discharge valve assembly. The lower discharge end of the silo pump is connected to the discharge pipe fitting via a flange. The silo pump is also equipped with an anti-clogging assembly. The anti-clogging assembly contains a rotary jetting mechanism driven by airflow. The rotary jetting mechanism is equipped with an air outlet nozzle that rotates with it. The airflow ejected from the air outlet nozzle cooperates with the airflow ejected from the fluidizing assembly to disperse dust and prevent compaction and clogging.

[0008] Preferably, the anti-clogging component includes a fixed base and a rotating component. Several fixing plates are connected to the outer side of the fixed base. The ends of the fixing plates are fixedly connected to the flange. The rotating component is rotatably mounted on the upper end of the fixed base. The fixing plates securely install the anti-clogging component in the center of the flange, ensuring that the rotating component does not move or shake when running in the chamber, thus providing a stable support foundation for the rotary jetting operation.

[0009] Preferably, the rotating component is a conical cavity component with a protrusion on its inner side forming a mounting groove. The upper end of the fixed bottom shell is placed in the mounting groove, and the two are rotatably connected by a dustproof bearing. The dustproof bearing is located below the protrusion, and the protrusion can physically shield the dustproof bearing, effectively blocking dust and ensuring the smooth rotation of the rotating component over a long period of time.

[0010] Preferably, the fixed base shell is provided with an inclined guide plate inside, and an air inlet pipe is mounted on the fixed base shell. One end of the air inlet pipe is located inside the fixed base shell and above the guide plate, and the other end extends to the outside of the pump. The inclined guide plate can accurately guide the airflow into the air inlet pipe to the drive component, improve the airflow utilization efficiency, and provide a stable and directional power source for the rotary drive.

[0011] Preferably, the rotating component has a driving component inside, which includes a fixed shaft, an impeller and several fixed rods. The impeller is fixed on the fixed shaft, and the two ends of the fixed rods are respectively connected to the fixed shaft and the protrusion. The impeller drives the rotating component to rotate under the drive of airflow.

[0012] Preferably, the outer wall of the rotating component is provided with a spiral blade, which rotates synchronously with the rotating component. The rotation of the spiral blade can agitate and assist in pushing the dust near the discharge port, effectively preventing dust accumulation and bridging, and further improving the smoothness of dust discharge.

[0013] Preferably, the upper end of the rotating component is connected to a crushing component, which includes a connecting pipe, a rotating pipe and an air outlet nozzle. The connecting pipe is connected to the inner cavity of the rotating component, and the two ends of the rotating pipe are respectively connected to the connecting pipe and the air outlet nozzle, thus constructing a continuous airflow delivery channel. This allows the airflow to be stably delivered to the air outlet nozzle, achieving rotary full-area blowing and all-round coverage of the dust compaction area.

[0014] Preferably, the air outlet nozzle has a unidirectional air outlet structure, which only allows airflow to be sprayed outward, preventing dust from flowing back into the rotating pipe and connecting pipe. When the blowing stops, the nozzle automatically closes, which can prevent dust backflow from clogging the pipe and nozzle, ensure the long-term stable operation of the blowing mechanism, and reduce equipment maintenance.

[0015] Preferably, the fluidizing component is a fluidizing plate, which sprays an upward-sloping airflow to form a synergistic dispersing structure with the rotating airflow from the outlet nozzle. The complementary cooperation of the two airflows can thoroughly disperse and compact the dust, avoiding further compaction of the dust caused by single upward blowing, thus solving the problem of dust compaction and blockage at the source.

[0016] Preferably, the connection points between the flange and the silo pump and the discharge pipe fitting are all equipped with sealing rings to ensure the sealing performance of the connection points, prevent gas leakage and dust overflow during system operation, maintain stable internal pressure of the silo pump, and ensure normal conveying operation.

[0017] Compared with the prior art, the present invention has the following beneficial effects: This invention solves the problem of dust compaction and discharge blockage caused by traditional single fluidized plate blowing by adding an anti-clogging component with an airflow-driven rotary jetting mechanism to the silo pump. This component works in synergy with the upward jetting airflow from the fluidized plate to comprehensively disperse compacted dust in the silo and break the binding force between dust particles. The dustproof bearing is physically shielded by the protruding part, ensuring the smooth operation of the rotating structure in the long term. The spiral blades on the outer wall of the rotating part can agitate and assist in pushing the dust, preventing accumulation and bridging at the discharge port. The sealing ring at the flange connection ensures the system's airtightness and maintains stable pressure in the silo. Overall, this invention improves the conveying efficiency and operational stability of the ash removal system, and reduces the risk of production interruption and maintenance costs.

They are merely simplified descriptions for the convenience of describing this invention and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this invention.

[0024] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0025] Example: Please see Figure 1-5A silo pump dust removal system includes a silo pump 1 and a feeding assembly 2, an air inlet assembly 3, a level gauge assembly 4, a pressure detection assembly 5, an exhaust assembly 6, a fluidization assembly 7, and a discharge pipe 8 installed on the silo pump 1. A discharge valve assembly 10 is installed on the discharge pipe 8. The lower discharge end of the silo pump 1 is connected to the discharge pipe 8 via a flange 11. The silo pump 1 is also equipped with an anti-clogging assembly 9. The anti-clogging assembly 9 has a rotary jetting mechanism driven by airflow. The rotary jetting mechanism is equipped with an air outlet nozzle 983 that rotates with it. The airflow ejected from the air outlet nozzle 983 cooperates with the airflow ejected from the fluidization assembly 7 to disperse dust and prevent compaction and clogging. The feeding assembly 2, air intake assembly 3, level gauge assembly 4, pressure detection assembly 5, and exhaust assembly 6 are all installed at preset positions on the outer wall of the silo pump 1 in accordance with conventional methods in the art. They respectively realize the functions of dust feeding, silo pressurization, real-time level monitoring, accurate pressure detection, and exhaust balance during the feeding and depressurization stages. The fluidization assembly 7 adopts a fluidization plate structure and is fixedly installed on the bottom inner side of the silo pump 1. Its blowing direction is inclined upward to provide basic fluidization power for the dust at the bottom. The discharge pipe 8 is connected to the discharge port at the lower end of the silo pump 1. The discharge valve assembly 10 adopts a wear-resistant valve commonly used in the art and is fixed on the discharge pipe 8 for precise control of the opening and closing of the discharge channel. The discharge end at the lower end of the silo pump 1 and the upper end of the discharge pipe 8 are detachably sealed through the flange 11. The contact surfaces of the flange 11 with the silo pump 1 and the discharge pipe 8 are all embedded with sealing rings. Through the compression and sealing of the sealing rings, gas leakage or dust overflow during system operation can be completely avoided, ensuring the airtightness and operational safety of the system.

[0026] The anti-clogging component 9 is installed inside the silo pump 1, directly above the discharge port. It forms a stable and rigid connection with the flange 11 through the fixing plate 92, ensuring that it remains fixed in position under high dust and high airflow impact conditions, providing a stable foundation for rotary jet cleaning. The fixing base 91 of the anti-clogging component 9 is a hollow cylindrical structure, with multiple fixing plates 92 evenly welded to its outer circumference. The free ends of the fixing plates 92 are bolted to the upper surface of the flange 11, so that the fixing base 91 is precisely positioned on the inner ring of the flange 11. At the center, a guide plate 93 is welded to the lower part of the fixed base shell 91 at an angle. The guide plate 93 completely closes the lower end of the fixed base shell 91, leaving only a channel for airflow to flow upward. An air inlet pipe 94 is also welded to the side wall of the fixed base shell 91. The inner end of the air inlet pipe 94 passes through the side wall of the fixed base shell 91 and extends to the top of the guide plate 93, while the outer end passes through the housing of the chamber pump 1 and extends to the outside. It is used to connect to an external high-pressure air supply device to provide a continuous and stable air source for the rotation drive and blowing operation of the anti-blocking component 9.

[0027] The rotating component 95, which mates with the fixed base 91, is a conical cavity component with its cone end pointing upwards. The lower end of its inner wall is integrally formed with a ring-shaped protrusion 951. The protrusion 951 and the inner wall of the rotating component 95 together form a ring-shaped mounting groove 952. The upper edge of the fixed base 91 extends into the mounting groove 952, and the two are rotated together by a dustproof bearing. The dustproof bearing is fitted at the bottom of the mounting groove 952 and is located directly below the protrusion 951. The protrusion 951 can provide all-round physical protection for the dustproof bearing, effectively preventing dust in the chamber pump 1 from falling directly into the bearing, avoiding jamming, wear or failure of the bearing due to dust intrusion, and ensuring that the rotating component 95 can rotate smoothly around the fixed base 91 for a long time.

[0028] A drive component 96 is fixedly installed in the internal cavity of the rotating component 95. The drive component 96 consists of a fixed shaft 961, an impeller 963, and multiple fixed rods 962. The fixed shaft 961 is arranged along the central axis of the rotating component 95. The impeller 963 is coaxially fixed in the middle section of the fixed shaft 961. The multiple fixed rods 962 are evenly distributed around the circumference of the fixed shaft 961. One end of each rod is welded to the upper end of the fixed shaft 961, and the other end is welded to the protrusion 951 on the inner side of the rotating component 95, forming a stable transmission connection. When the air inlet pipe 94 sends high-pressure airflow into the fixed bottom shell 91, the airflow will be guided by the guide plate 93 and will rush upward in an inclined direction to the blades of the impeller 963, thereby driving the impeller 963 to rotate at high speed. The rotational power of the impeller 963 is synchronously transmitted to the rotating component 95 through the fixed shaft 961 and the fixed rods 962, ultimately driving the rotating component 95 to rotate around the fixed bottom shell 91.

[0029] On the conical outer wall of the rotating component 95, a spiral blade 97 spiraling upward is welded. The spiral blade 97 is an integral structure with the rotating component 95 and can rotate synchronously with the rotating component 95. During its rotation, it will continuously agitate, guide, and assist in pushing the dust near the discharge port in the silo pump 1, which can effectively prevent dust from accumulating and bridging above the discharge port, and further ensure the orderly movement of dust towards the discharge port. The top of the conical end of the rotating component 95 is also connected to a crushing component 98. The crushing component 98 consists of a connecting pipe 981, a rotating pipe 982, and an air nozzle 983. The connecting pipe 981 is a vertically arranged hollow tube, the lower end of which is connected to the top of the conical end of the rotating component 95, and the upper end is a closed structure. The rotating pipe 982 is a hollow tube with a vertical arrangement. 982 is a horizontally arranged hollow tube, one end of which is connected to the side wall of the connecting pipe 981, and the other end is connected to the air outlet nozzle 983. This allows the high-pressure airflow inside the rotating component 95 to pass through the connecting pipe 981 and the rotating pipe 982 in sequence, and finally be sprayed out from the air outlet nozzle 983 into the dust area inside the chamber pump 1. The air outlet nozzle 983 adopts a valve-type structure with one-way air outlet that is already available in the prior art. It only allows airflow to be sprayed out from the inside of the nozzle to the outside. When the air supply stops, the valve plate of the nozzle will automatically close under its own elastic force, which can effectively prevent the dust in the chamber pump 1 from flowing back into the rotating pipe 982 and the connecting pipe 981 from the nozzle, avoid the pipeline and nozzle from being blocked due to dust backflow, and ensure the long-term reliability of the anti-blocking component 9.

[0030] The core technical advantage of this invention lies in the dual-airflow synergistic anti-clogging mechanism of the fluidizing component 7 and the anti-clogging component 9. The fluidizing plate of the fluidizing component 7 sprays an upward-sloping airflow, which can form basic fluidization of the dust at the bottom of the silo pump 1. Meanwhile, the air outlet nozzle 983 rotates at high speed with the rotating component 95, which can achieve full-area coverage of the discharge area of ​​the silo pump 1. The rotating airflow and the upward-sloping airflow of the fluidizing plate intertwine and complement each other, which can penetrate the dust layer from the bottom up and also rotate and disperse the dust from the top of the discharge port. The combined force of the two airflows can destroy the binding force between dust particles in all directions, and completely disperse the already compacted dust clumps. This avoids the problem of dust being further compacted due to the traditional single fluidizing plate spraying. At the same time, it can also guide the dust to move in an orderly manner towards the discharge port in a uniform and dispersed state, avoiding large dust particles from falling into the discharge pipe 8, and fundamentally reducing the risk of blockage in the discharge pipe 8 and subsequent conveying pipelines.

[0031] The complete working process of the silo pump dust removal system is coherent and highly automated. After the system starts, the exhaust component 6 is first turned on to balance the exhaust in the silo. Then the feed component 2 is turned on, and the dust falls into the silo pump 1 under the action of gravity. The level gauge component 4 monitors the material level in the silo in real time. When the dust reaches the preset material level, the feed component 2 and the exhaust component 6 are automatically turned off. Then the air intake component 3 is turned on to introduce high-pressure gas into the silo pump 1 for pressurization. The pressure detection component 5 monitors the pressure in the silo in real time. When the pressure reaches the preset conveying pressure, the air intake component 3 stops working, and the discharge valve component 10 opens simultaneously, and the system enters the discharge stage. At the start of the discharge stage, the fluidization component 7 and the anti-clogging component 9 are activated simultaneously. The fluidization plate sprays an upward-sloping airflow to fluidize the dust at the bottom. The air inlet pipe 94 introduces high-pressure airflow into the fixed bottom shell 91. The airflow drives the impeller 963 to rotate, which in turn drives the rotating component 95, the spiral blade 97, and the crushing component 98 to rotate synchronously. The high-pressure airflow is sprayed out from the outlet nozzle 983 through the connecting pipe 981 and the rotating pipe 982. The rotating jet airflow and the airflow of the fluidization plate work together to completely disperse the compacted dust. The 97 plate simultaneously guides the dust, allowing it to enter the discharge pipe 8 through the discharge port in a uniformly dispersed state. Finally, it is transported to the designated position under the push of high-pressure gas. When the dust inside the silo pump 1 is completely transported, the pressure detection component 5 detects that the pressure inside the silo has dropped to the preset lower limit, the discharge valve component 10 automatically closes, and the fluidization component 7 and the anti-blocking component 9 also stop working. The system completes one working cycle and waits for the next feeding command. This process is repeated to achieve continuous, stable and efficient dust removal and conveying operations.
