Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and in particular to a silo. Background Technology

[0002] Large rectangular silos, as key facilities for large-scale industrial production, often have a single silo capacity of tens of cubic meters, with material storage capacity typically measured in tens of tons. While this large-scale design improves storage efficiency, it also brings significant challenges to material flow. Due to the geometric characteristics of rectangular silos, materials tend to accumulate unevenly within the silo, and bridging effects frequently occur during unloading, preventing materials from being discharged smoothly.

[0003] In related technologies, to solve the bridging problem, methods such as strong mechanical stirring or high-power vibrators are usually used, but these methods are energy-intensive, prone to jamming, and have a great impact on the silo structure. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, one objective of this invention is to provide a hopper that, through a sliding carriage located at the bottom of the storage chamber, can apply mechanical shearing force to the material clumps at the bottom of the storage chamber. Simultaneously, a blower pipe located above the carriage sprays airflow onto the clumps, and through the synergistic effect of mechanical and pneumatic forces, impacts, breaks up, and loosens the clumps, restoring its fluidity, reducing energy consumption and the probability of jamming, and minimizing the impact on the hopper body.

[0005] This utility model provides a silo, which includes a silo body, an arch-breaking mechanism, and a discharge mechanism. The silo body defines a storage cavity, and a discharge port is provided at the bottom of the silo body, which communicates with the storage cavity. The arch-breaking mechanism includes a slide and a jet pipe. The jet pipe is horizontally positioned across the bottom of the storage cavity, and the slide is slidably positioned below the jet pipe. The jet pipe has multiple jet nozzles for jetting airflow. The discharge mechanism is located at the discharge port.

[0006] In some embodiments, the blowpipe is provided with at least two sets of air nozzles, the air nozzles comprising at least two air nozzles spaced apart along the axial direction of the blowpipe.

[0007] In some embodiments, at least two sets of the jet nozzles are located at different circumferential positions on the jet pipe.

[0008] In some embodiments, at least two sets of the jet nozzles are offset axially from each other in the blowpipe.

[0009] In some embodiments, the jet nozzle includes a horizontally upward-sloping jet nozzle and a horizontally downward-sloping jet nozzle.

[0010] In some embodiments, the number of the blowpipes is multiple, and the multiple blowpipes are spaced apart along the length of the storage cavity.

[0011] In some embodiments, the arch-breaking mechanism further includes a carriage drive assembly; the carriage drive assembly is located outside the storage cavity; the drive end of the carriage drive assembly passes through a first opening in the hopper body via a dynamic sealing structure to connect to the carriage.

[0012] In some embodiments, a second opening is provided on the hopper body; the blowpipe passes through the second opening and a sealing structure is provided between the blowpipe and the second opening, and the air inlet of the blowpipe is located outside the storage cavity.

[0013] In some embodiments, the arch-breaking mechanism further includes a high-pressure gas supply component connected to the jet pipe to supply high-pressure gas to the jet pipe, wherein the pressure of the high-pressure gas is 0.6~0.8 MPa.

[0014] In some embodiments, the arch-breaking mechanism further includes a pulse valve, which is installed at the air inlet of the blowpipe and is used to control the opening and closing of the air inlet.

[0015] As can be seen from the technical solution, the embodiments provided by this utility model have the following advantages:

[0016] (1) The continuous mechanical shearing force provided by the carriage and the airflow injected through the jet nozzle work together to break the arching and compaction of the material, efficiently restore its fluidity, and improve the continuity and stability of the discharge.

[0017] (2) The airflow impact can loosen and partially fluidize the agglomerated material, reduce the blockage of the slide by the block material, and significantly reduce the sliding resistance of the slide. This not only reduces the wear of mechanical parts, but also improves the reliability of the arch breaking mechanism.

[0018] (3) Based on the above synergistic effect, the carriage does not need to overcome extremely large initial resistance, so a drive device with lower power and lower cost can be selected. Compared with the traditional solution of simply increasing the drive power, this embodiment achieves better arch breaking effect and lower overall manufacturing cost by introducing a low-cost blow pipe.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The following is for reference. Figures 1-3 Describes a hopper 100 according to an embodiment of the present utility model.

[0033] Example 1

[0034] like Figure 1 As shown, this utility model provides a silo 100, which includes a silo body 1, an arch-breaking mechanism 2, and a discharge mechanism 3. The silo body 1 forms a storage cavity 10, and a discharge port 11 is opened at the bottom of the silo body 1, which communicates with the storage cavity 10. The arch-breaking mechanism 2 includes a slide 21 and a jet pipe 22. The jet pipe 22 is horizontally arranged across the bottom of the storage cavity 10, and the slide 21 is slidably arranged below the jet pipe 22. The jet pipe 22 has multiple jet nozzles 220 for jetting airflow. The discharge mechanism 3 is located at the discharge port 11.

[0035] The blow pipe 22 here is located across the bottom of the storage cavity 10. The blow pipe 22 being located above the bottom wall of the storage cavity 10 means that the carriage 21 slides above the bottom wall of the storage cavity 10, and its sliding trajectory is located in the projection area below the blow pipe 22.

[0036] In a specific application scenario, the storage chamber 10 contains sludge. When the material accumulates to a deep depth, the sticky sludge rubs, compresses, and clumps together, making it difficult for the material to be discharged from the outlet 11. The slide 21 applies mechanical shearing force to the clumped material at the bottom of the storage chamber 10 by sliding. At the same time, the blowpipe 22 above the slide 21 sprays airflow onto the clumped material. Through the combined action of mechanical and pneumatic forces, the clumped material is impacted, broken, and loosened, restoring its fluidity. This allows the material to be smoothly discharged through the outlet 11 at the bottom, and finally unloaded by the unloading device.

[0037] It should be noted that the sliding of the slide 21 needs to overcome the resistance of the sludge, and some materials may jam the slide 21 when they clump together, preventing it from sliding. In this embodiment, the jet nozzle 220 sprays airflow to impact the clumped material. The kinetic energy of the high-pressure gas is used to directly break the bridging structure, preventing the clumped material from moving with the slide 21, thereby reducing the sliding resistance of the slide 21. Therefore, when selecting the slide 21 drive device, a lower-cost and lower-power drive device can be selected. Moreover, compared with the improved technical solution of increasing the power of the slide 21 drive device, the cost of setting the jet nozzle 22 is lower.

[0038] As can be seen from the technical solution, the embodiments provided by this utility model have the following advantages:

[0039] (1) The continuous mechanical shearing force provided by the slide 21 and the airflow injected by the blow pipe 22 through the air nozzle 220 work together to break the arching and compaction of the material, efficiently restore its fluidity, and improve the continuity and stability of the discharge.

[0040] (2) The airflow impact can loosen and partially fluidize the agglomerated material, reduce the blockage of the slide 21 by the block material, and significantly reduce the sliding resistance of the slide 21. This not only reduces the wear of mechanical parts, but also improves the reliability of the arch breaking mechanism 2.

[0041] (3) Based on the above synergistic effect, the carriage 21 does not need to overcome a large initial resistance, so a drive device with lower power and lower cost can be selected. Compared with the traditional solution of simply increasing the drive power, this embodiment achieves better arch breaking effect and lower overall manufacturing cost by introducing a low-cost blow pipe.

[0042] For example, the unloading mechanism 3 can be a continuous unloading device commonly used in the art, such as, but not limited to, a rotary valve or a screw conveyor. A rotary valve can achieve uniform feeding and airtight sealing to prevent gas leakage from the silo; a screw conveyor has both conveying and a certain degree of sealing function, and can be selected according to actual process requirements.

[0043] like Figure 2 As shown, the arch-breaking mechanism 2 further includes a carriage drive assembly 23; the carriage drive assembly 23 is located outside the storage cavity 10; the drive end of the carriage drive assembly 23 passes through the first opening of the hopper body 1 through a dynamic sealing structure to connect to the carriage 21.

[0044] The carriage drive assembly 23 here can specifically be a hydraulic cylinder, an electric push rod, or a pneumatic cylinder. The body of the carriage drive assembly 23 (such as the cylinder body, motor, etc.) is located outside the storage cavity 10. The drive end of the carriage drive assembly 23 (such as the piston rod of the hydraulic cylinder or the rod body of the push rod) extends into the storage cavity 10 through the first opening on the hopper body 1 and is mechanically connected to the carriage 21 located in the storage cavity 10. A dynamic sealing structure (such as a stuffing box, lip seal, or combined seal) is provided at the gap where the drive end passes through the first opening, which can continuously and effectively seal the annular gap between the drive end and the first opening during the reciprocating motion of the drive end.

[0045] For example, a one-way valve is also provided at the jet nozzle 220. The direction of the one-way valve is configured to allow the airflow inside the jet pipe 22 to be ejected outward, while preventing the material (such as sludge or powder) in the storage chamber from flowing back into the internal cavity of the jet pipe 22 through the jet nozzle 220.

[0046] Example 2

[0047] This embodiment is basically the same as Embodiment 1, except for the specific structure of the blow pipe 22.

[0048] like Figure 3 As shown, the blowpipe 22 is further provided with at least two sets of air nozzles, each set of air nozzles including at least two air nozzles 220, and the at least two air nozzles 220 are spaced apart along the axial direction of the blowpipe 22.

[0049] In conjunction with the above embodiments, the blowpipe 22 is positioned across the bottom of the storage chamber 10. Through multiple air nozzles 220 spaced apart along the axial direction of the blowpipe 22, a single blowpipe 22 constitutes a linearly distributed multi-point air source, thereby enabling the spraying of airflow onto the arched material in a strip-shaped area parallel to its own axial direction, greatly improving the coverage and efficiency of the pneumatic arch breaking.

[0050] like Figure 3 As shown, furthermore, at least two sets of jet nozzles are located at different circumferential positions on the jet pipe. These jet nozzle sets are not all located on the same generatrix of the jet pipe, but can be located at different angles in their radial direction. For example, one set of jet nozzles 220 can be located at the bottom of the pipe wall of the jet pipe 22, while the other set can be located on the side of the pipe wall of the jet pipe 22. By setting the jet nozzles 220 at different circumferential positions, the high airflow can impact the material from multiple directions, forming a three-dimensional impact force field from the oblique, lateral, and upward directions, reducing the flow dead zones that are difficult to reach by traditional single-direction airflow.

[0051] like Figure 3As shown, at least two sets of jet nozzles are staggered along the axial direction of the jet pipe. These at least two sets of jet nozzles, positioned at different locations around the circumference of the jet pipe 22, are staggered rather than aligned along the axial direction of the jet pipe. This means that, using the axis of the jet pipe 22 as a reference, each jet nozzle in one set and its corresponding jet nozzle in the other set are not at the same projected position along the axial direction, but are spaced apart and staggered. This staggered arrangement avoids multiple high-intensity airflows concentrating at the same position along the axial direction of the jet pipe 22, dispersing the impact force of the airflow to more points along the axial direction. This not only makes the energy of the airflow more evenly distributed at the bottom of the chamber, improving energy utilization efficiency, but also reduces local fatigue damage to the jet pipe 22 caused by concentrated reaction forces, thus extending the service life of the equipment.

[0052] like Figure 3 As shown, the jet nozzle 220 further includes a horizontally upward-sloping jet nozzle 220 and a horizontally downward-sloping jet nozzle 220. This means that through the horizontally upward-sloping jet nozzle 220 and the horizontally downward-sloping jet nozzle 220, the airflow can be directed at different spatial areas around the blowpipe 22 at different elevation and depression angles. The upward-sloping airflow can impact and loosen the caking material located above and to the sides of the blowpipe 22, effectively acting on the arched areas that are difficult for the carriage 21 or the silo wall to directly access. The downward-sloping airflow concentrates its energy to impact and clean the material at the bottom of the storage chamber 10, and reduces the accumulation of fine particles below the blowpipe 22. The combination of these two elements forms a three-dimensional arch-breaking force field that simultaneously covers the horizontal, vertical, and inclined planes, providing a more comprehensive arch-breaking dimension.

[0053] like Figure 3 As shown, further, there are multiple blowpipes 22, which are spaced apart along the length of the storage cavity 10. These blowpipes 22 are arranged in parallel at certain intervals along the length of the storage cavity 10, together forming an array-type pneumatic arch-breaking system covering the bottom of the storage cavity 10, further increasing the arch-breaking range.

[0054] like Figure 3 As shown, the arch-breaking mechanism 2 further includes a high-pressure gas supply component 24, which is connected to the jet pipe 22 to supply high-pressure gas to the jet pipe 22. The pressure of the high-pressure gas is 0.6~0.8 MPa. The pressure of the high-pressure gas supplied to the jet pipe 22 by the high-pressure gas supply component 24 is stabilized within the preferred range of 0.6~0.8 MPa. This pressure value provides the airflow with sufficient kinetic energy to effectively impact and break the compacted structure of the mud and powder materials, while avoiding a sharp increase in energy consumption and excessive equipment load due to excessive pressure, thus improving the balance between arch-breaking efficiency and economy.

[0055] like Figure 3As shown, the arch-breaking mechanism 2 further includes a pulse valve 25, which is installed at the air inlet of the blowpipe 22 and used to control the opening and closing of the air inlet. Through the pulse valve 25 installed at the air inlet of the blowpipe 22, the pulse valve 25 can be controlled by the program controller to open and close sequentially, automatically, and instantaneously at set intervals. This working mode transforms continuous air supply into a series of transient high-energy pulse shock waves. Each pulse release instantaneously forms a pulse airflow with an intensity far exceeding the continuous airflow inside the blowpipe 22, which is ejected at high speed from the nozzle, producing an explosive impact on the material, significantly improving arch-breaking efficiency while greatly reducing compressed air consumption.

[0056] Combination Figure 1 , Figure 2 and Figure 3 As shown, the silo body 1 is further provided with a second opening; the blow pipe 22 passes through the second opening and a sealing structure is provided between the blow pipe 22 and the second opening, and the air inlet of the blow pipe 22 is located outside the storage cavity 10.

[0057] As described in the above embodiments, each blowpipe 22 on the silo body 1 has a corresponding second opening, through which the blowpipe 22 extends into the storage chamber 10. A reliable sealing structure (e.g., a stuffing box, sealing ring assembly, etc.) is provided at the interface between the blowpipe 22 and the second opening, thus both fixing the blowpipe 22 and preventing material leakage from the silo through this gap. Finally, the air inlet of the blowpipe 22 and the connected pulse valve 25 are both located in the external space of the storage chamber 10.

[0058] The following is combined Figures 1-3 Describe a specific example.

[0059] The hopper 100 includes a base frame 4, a hopper body 1, a discharge mechanism 3, a slide 21, a slide drive assembly 23, a blow pipe 22, a high-pressure gas supply assembly 24, and a pulse valve 25.

[0060] The silo body 1 is fixed on the base frame 4. The silo body 1 has a storage cavity 10 inside, and the cavity 10 is rectangular in shape. The bottom of the silo body 1 has a discharge port 11, which penetrates the bottom wall of the storage cavity 10 to connect with the storage cavity 10. The silo body 1 also has a feed port, which is located at the top of the silo body 1. For example, the feed port can penetrate the side wall of the storage cavity 10 near the top or penetrate the top wall of the storage cavity 10. Thus, feeding and unloading can rely on the weight of the material to enter or exit the storage cavity 10.

[0061] The unloading structure is specifically constructed as a conveying screw conveyor. The unloading structure is installed below the silo body 1 and the inlet of the conveying screw conveyor is sealed to the outlet 11 of the silo body 1.

[0062] The slide 21 is slidably installed inside the storage cavity 10 and is located at the bottom of the storage cavity 10. A first opening is provided on the hopper body 1, which penetrates the hopper body 1 and connects to the storage cavity 10. The slide drive assembly 23 is constructed as a hydraulic cylinder, with the cylinder body fixedly mounted on the base frame 4. The drive rod of the hydraulic cylinder passes through the first opening and is mechanically connected to the slide 21. A dynamic sealing structure is provided between the drive rod and the first opening to fill the annular gap between the drive rod and the first opening. Driven by the slide drive assembly 23, the slide 21 can translate along the length of the storage cavity 10. On the one hand, the continuous mechanical shearing force provided by the slide 21 can break up the arching and compaction of the material, efficiently restoring its fluidity and improving the continuity and stability of the discharge. On the other hand, when the slide 21 translates, it pushes the material to the discharge port 11, thereby assisting in the discharge of the material.

[0063] The high-pressure gas supply assembly 24 includes an air compression tank, the air compression tank being maintained at a set air pressure of 0.6-0.8 MPa.

[0064] There are five jet pipes 22. These five jet pipes 22 are spaced apart along the length of the storage chamber 10, with the same spacing between the axes of adjacent jet pipes 22. The air compression tank has an air outlet, and the air outlet, the air inlet of the jet pipe 22, and the pulse valve 25 are arranged in a one-to-one correspondence. The air outlet of the tank and the air inlet of the jet pipe 22 are connected by the pulse valve 25. The five pulse valves 25 automatically and instantaneously open and close sequentially at programmed intervals.

[0065] Each jet pipe 22 has a diameter of 89mm to 108mm. Each jet pipe 22 is provided with two jet nozzle groups, one jet nozzle group is the first jet nozzle group 221, and the other jet nozzle group is the second jet nozzle group 222. The first jet nozzle group 221 and the second jet nozzle group 222 are respectively located at different positions in the circumferential direction of the jet pipe 22.

[0066] The first jet nozzle group 221 includes three jet nozzles 220 spaced apart along the axial direction of the jet pipe 22, and the second jet nozzle group 222 includes three jet nozzles 220 spaced apart along the axial direction of the jet pipe 22. Along the axial direction of the jet pipe 22, the three jet nozzles of the first jet nozzle group 221 are staggered from the three jet nozzles of the second jet nozzle group 222. The jet nozzles 220 in the first jet nozzle group 221 are horizontally inclined downwards at an angle of α, and the jet nozzles 220 in the second jet nozzle group 222 are horizontally inclined upwards at an angle of β, where α is 15°~25° and β is 15°~25°.

[0067] It is important to emphasize that the large rectangular silo 100, as a key facility for industrial-scale production, often has a single silo capacity of tens of cubic meters, with material storage capacity typically measured in tens of tons. While this large-scale design improves storage efficiency, it also brings significant challenges to material flowability. Due to the geometric characteristics of the rectangular silo 100, materials tend to accumulate unevenly within the silo, frequently resulting in bridging effects during the unloading process. This prevents materials from being discharged smoothly, especially when handling highly viscous, poorly flowing powdery sludge, which is more likely to clump and form severe bridging above the slide 21, rendering the slide 21 unloading device ineffective.

[0068] In the rectangular silo 100, when the material accumulates to a deep depth, the internal friction and compression of the sticky powdery sludge easily leads to caking. This bridging effect causes the material to clump together above the slide 21 and move with the slide 21, resulting in ineffective unloading. The clumped sludge may even jam the slide 21, causing the hydraulic cylinder to overload and trip, resulting in a shutdown.

[0069] Known methods for breaking up sludge bridging, such as vibration and flow-blocking disc methods, have limited effect on the internally agglomerated material when vibrating the side of the silo. The flow-blocking disc method, due to its small air volume, disc vibration amplitude, and spraying area, is ineffective against large, hardened sludge clumps in the central part of the silo 100. These methods cannot fundamentally solve the problem of sludge bridging on the slide 21 of the rectangular silo 100, necessitating a more efficient solution.

[0070] Based on the aforementioned problems, this patent addresses the clumping issue in the rectangular silo 100 by designing a novel arch-breaking technology. A high-pressure gas nozzle with a diameter of 89-108 mm is installed above the slide 21, using pulsed air jets to impact the clumped material. This method utilizes the kinetic energy of the high-pressure gas to directly disrupt the bridging structure, while simultaneously preventing the clumped material from moving with the slide 21.

[0071] Specifically, gas impact can disperse clumps of powdered sludge over a large area, loosening the sludge and restoring its fluidity. The sludge then falls into the conveying system under the influence of gravity and the slide 21. Experiments show that this technology can significantly reduce bridging frequency, improve feeding efficiency, and greatly reduce the probability of the slide 21 jamming and causing tripping and shutdown, without requiring additional equipment size or material costs.

[0072] The hopper 100 in this example has the following advantages:

[0073] (1) High-efficiency breaking of bridging: High-pressure gas (pressure range is usually 0.6-0.8MPa) pulse jet blowing is adopted, with a nozzle diameter of 89-108mm. It can form a strong gas impact above the slide 21, which directly acts on the arch bridge structure of the bridging material, realizes large-scale loosening, and restores the fluidity of the material. It effectively solves the problems of small action area and insufficient impact force of traditional vibration method and flow-assisted air butterfly method.

[0074] (2) Significantly reduce the risk of equipment downtime: By preventing materials from moving with the slide 21 and jamming the equipment, this device greatly reduces the probability of the slide 21 cylinder jumping out and stopping due to overload, and improves the continuity and stability of equipment operation. It is especially suitable for large square silos 100 with a single silo capacity of tens of cubic meters and a storage capacity of tens of tons.

[0075] (3) Adaptability and simple maintenance: The structure of the blow pipe 22, high-pressure gas supply component 24 and pulse valve 25 is simple. They are installed above the slide 21, without occupying additional equipment space, and do not require changes to the original structure of the silo body 1. It is suitable for sludge and other similar materials with high viscosity and poor flowability. Pulse control is achieved by setting the pulse valve 25, and the blowing frequency and duration can be adjusted according to the actual degree of material caking to achieve precise and energy-saving operation. The main body of the system is made of corrosion-resistant steel, without a complex mechanical transmission structure, with a low failure rate, and is convenient for daily inspection and component replacement.

[0076] (3) Economical and practical with low-cost operation and maintenance: Compared with the addition of complex mechanical arch-breaking mechanism 2 or high-frequency vibration equipment, this technology uses compressed air as a power source and adopts pulse control mode. Each spray lasts for no more than 0.5 seconds, which effectively reduces air consumption and operation. It has low energy consumption, fewer parts, and long service life, which greatly reduces the equipment manufacturing cost and subsequent maintenance cost. It is suitable for large-scale industrial promotion.
