Description

Technical Field

[0001] This utility model relates to the field of modified powder storage technology, and in particular to a centralized storage bin for modified powder. Background Technology

[0002] Powder modification refers to the treatment of powder surfaces through physical, chemical, and mechanical methods to change their physicochemical properties or endow them with new functions.

[0003] After modification and production, powders are stored in storage silos before packaging and transportation. However, existing temporary storage silos are mostly equipped with a silo body and inlet / outlet pipes. Although they meet basic operational requirements, the fast discharge speed and large discharge volume make them prone to arching. When materials enter the silo for storage, dust will be generated due to the light weight of the powder. If the external environment is humid, condensation will occur on the inner wall of the temporary storage silo. At this time, some powder particles will stick to the inner wall of the temporary storage silo, which will cause certain chemical reactions and affect the product performance. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a modified powder centralized storage bin.

[0005] The technical solution of this utility model is achieved through the following scheme: a modified powder centralized storage silo, including a protective outer silo, a storage inner silo, a cover and an auger screw conveyor. The protective outer silo is fitted onto the outer surface of the storage inner silo through a shock-absorbing protective layer. A cover is detachably installed at the opening of the protective outer silo. The cover is provided with a feed pipe and a sealing drive plate. Several material stabilizing slopes are fixedly provided on the inner wall of the storage inner silo. The material stabilizing slopes are directly opposite the feed pipe. The auger screw conveyor passes through the protective outer silo and the storage inner silo. The outer surface of the storage inner silo is covered with a condensation barrier.

[0006] The material release ramp is arched and has several material discharge holes.

[0007] Through the above technical solutions, the slow-moving slope effectively blocks the direct impact and rapid fall of the powder. The arched design allows the powder to disperse and slide down the surface of the slope after contacting it, changing the original concentrated falling trajectory of the powder. Furthermore, a portion of the powder is preferentially discharged through the discharge hole, increasing the channel and flowability of the powder and preventing the powder from accumulating and arching in a certain area of ​​the silo. The double-layer storage combined with the condensation partition effectively prevents humid air from the external environment, thus avoiding condensation on the inner wall due to the temperature difference between the inside and outside, ensuring the stability of the modified powder storage. The shock-absorbing protective layer ensures the stability of the inner silo during large-volume discharge, ensuring the stability of the double-layer storage structure.

[0008] Preferably, the bottom of the inner cavity of the storage compartment is provided with a discharge slope and an auger moving groove. An agitator is provided on the discharge slope, the lowest point of the discharge slope is connected to the auger moving groove, and the agitator abuts against the slope surface of the discharge slope.

[0009] Preferably, the shock-absorbing protective layer includes several shock-absorbing airbags and several buffer spring columns. Several shock-absorbing airbags are provided between the outer surface of the inner storage compartment and the inner wall of the outer protective compartment. The inner storage compartment is connected to the outer protective compartment through the buffer spring columns.

[0010] Through the above technical solutions, the discharge slope provides a natural downward guide for the powder, ensuring that the powder can enter the auger's moving trough in a concentrated and smooth manner, providing good material aggregation conditions for the subsequent conveying of the powder by the auger screw conveyor; the continuous rotation of the agitator fan ensures that the powder is evenly spread and slides down the discharge slope; the buffer spring column and the shock-absorbing airbag work together to absorb and disperse vibration energy. At the same time, the buffer spring column can limit the position of the inner storage chamber, improve the anti-interference ability of the storage chamber, protect the double-layer structure of the inner and outer chambers, and ensure the normal operation of the storage chamber.

[0011] Preferably, the cover has sealing lines, a movable groove inside the cover, and a sliding groove. The sealing drive plate is movably installed in the movable groove, and a sealing block is snapped onto one side of the cover, the sealing block being adapted to the movable groove.

[0012] Preferably, the sealing drive plate includes a linear actuator and a sealing baffle. The linear actuator is detachably installed on the top surface of the cover. The telescopic end of the linear actuator is connected to the sealing baffle. The sealing baffle is movably installed in the movable groove. The telescopic end of the linear actuator is located in the sliding groove. The sealing lines are located on both sides of the sliding groove.

[0013] Preferably, a protective conveying pipe is attached to the outer surface of the storage compartment, and the screw conveyor passes through the protective conveying pipe and the storage compartment.

[0014] Preferably, the protective outer chamber has through holes that are compatible with the protective conveying pipe.

[0015] Through the above technical solutions, the linear actuator can quickly and accurately push the sealing baffle to complete the sealing, improving the overall sealing performance of the storage bin. The sealing markings clearly define the sealing location and provide a clear visual reference for the sealing operation. Simply remove the sealing block and move the linear actuator to the maximum distance of the slide, and the sealing baffle will push all the powder in the movable trough out along the preset path, ensuring that there are no dead corners in the cleaning and timely cleaning of the powder that has entered the movable trough. This effectively prevents the powder that enters the movable trough during feeding from accumulating and clumping inside the movable trough.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. This utility model effectively blocks the direct impact and rapid fall of powder through a slowing slope. The arched design allows the powder to disperse and slide down the surface of the slope after contacting it, changing the original concentrated falling trajectory of the powder. Furthermore, a portion of the powder is preferentially discharged through the discharge hole, increasing the channel and flowability of the powder and preventing the powder from accumulating and arching in a certain area of ​​the silo. The double-layer storage combined with the condensation partition effectively prevents humid air from the external environment, thus avoiding condensation on the inner wall due to the temperature difference between the inside and outside, ensuring the stability of the modified powder storage. The shock-absorbing protective layer ensures the stability of the inner silo during large-volume discharge, ensuring the stability of the double-layer storage structure.

[0018] 2. The discharge slope provides a natural guide for the powder to slide down, ensuring that the powder can enter the auger's moving trough in a concentrated manner, providing good material aggregation conditions for the subsequent conveying of the powder by the auger screw conveyor; the agitator fan rotates continuously, so that the powder is evenly spread and ensures that the powder slides down along the discharge slope; the buffer spring column and the shock-absorbing airbag work together to absorb and disperse vibration energy. At the same time, the buffer spring column can limit the position of the inner storage bin, improve the anti-interference ability of the storage bin, protect the double-layer structure of the inner and outer bins, and ensure the normal operation of the storage bin.

[0019] 3. The linear actuator quickly and accurately pushes the sealing baffle to complete the sealing, improving the overall sealing performance of the storage bin. The sealing markings clearly define the sealing location and range, providing a clear visual reference for the sealing operation. Simply remove the sealing block and move the linear actuator to the maximum distance of the slide, and the sealing baffle will push all the powder in the movable trough out along the preset path, ensuring thorough cleaning without dead corners and timely removal of powder entering the movable trough. This effectively prevents powder entering the movable trough during feeding from accumulating and clumping inside the movable trough. Attached Figure Description

[0028] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] A modified powder centralized storage silo, such as Figures 1-7 As shown, the system includes a protective outer chamber 1, a storage inner chamber 2, a cover 3, and an auger conveyor 5. The protective outer chamber 1 is fitted onto the outer surface of the storage inner chamber 2 via a shock-absorbing protective layer 4. The cover 3 is detachably installed at the opening of the protective outer chamber 1. The cover 3 is equipped with a feed pipe 10 and a sealing drive plate 6. Several buffer slopes 21 are fixedly installed on the inner wall of the storage inner chamber 2. The auger conveyor 5 passes through the protective outer chamber 1 and the storage inner chamber 2. The outer surface of the storage inner chamber 2 is covered with a condensation layer 7, which is preferably a polytetrafluoroethylene (PTFE) sheet with a thickness of 3 mm. A gap exists between the storage inner chamber 2 and the protective outer chamber 1, and the shock-absorbing protective layer 4 is installed within the gap. The shock-absorbing protective layer 4 is connected to the condensation partition 7 of the inner storage chamber 2 on one side and to the outer protective chamber 1 on the other side. The shock-absorbing protective layer 4 can absorb and disperse some energy, reduce the impact of material feeding and external vibration on the powder in the inner storage chamber 2, and ensure the stability and safety of powder storage. The outer protective chamber 1 provides an external protective shell for the entire device. Together with the condensation partition 7, it protects the powder in the inner storage chamber 2 from the influence of the external ambient temperature. The sealing drive plate 6 controls the opening and closing of the feed pipe 10 as needed. When the powder is full or no further feeding is required, the feed pipe 10 can be sealed by the sealing drive plate 6 to prevent powder leakage.

[0031] The gap layer can effectively slow down temperature penetration. Together with the condensation layer 7, it forms a double protection. The gap layer first buffers temperature changes, while the condensation layer 7 further plays its role in isolating humid gases from the outside, making it difficult for external temperatures to directly affect the powder in the storage chamber 2.

[0032] like Figure 1 As shown, an observation window is also provided on the cover 3 to observe the amount of powder stored inside.

[0033] like Figure 2 As shown, the slowing slope 21 is directly opposite the feed pipe 10. The slowing slope 21 is arched, and the number of two is preferred. It is integrated with the storage inner silo 2. The slowing slope 21 is provided with several discharge holes. During the falling process, the powder needs to slide along the slope surface to increase the falling path of the powder and effectively slow down the falling speed of the powder. When the powder flows on the slowing slope 21, some of the powder will fall through the discharge holes, further dispersing the falling process and avoiding the impact caused by the concentrated and rapid falling of the powder, making the falling speed more stable and controllable.

[0034] like Figure 5 As shown, a protective conveying pipe 8 is connected to the outer surface of the inner storage chamber 2. An auger screw conveyor 5 passes through the protective conveying pipe 8 and the inner storage chamber 2. The auger screw conveyor 5 includes a servo motor and a screw conveying roller. The servo motor is mounted on the platform of the outer protective chamber 1 and installed on the protective conveying pipe 8 on one side of the inner storage chamber 2. The protective conveying pipe 8 on the other side has a discharge port. The protective conveying pipe 8 is adapted to the screw conveying roller. The protective conveying pipe 8 consists of two sections, which are respectively set on both sides of the through groove in the inner storage chamber 2 through which the screw conveying roller passes.

[0035] The outer protective chamber 1 has through holes that are compatible with the protective conveying pipe 8, which mechanically limits the protective conveying pipe 8 and prevents the spiral conveying roller inside the protective conveying pipe 8 from colliding with the inner storage chamber 2.

[0036] like Figure 7 As shown, the bottom of the inner cavity of the storage chamber 2 is provided with a discharge slope 23 and an auger trough. An agitator 22 is provided on the discharge slope 23. The lowest point of the discharge slope 23 is connected to the auger trough. The agitator 22 abuts against the slope surface of the discharge slope 23. The slope of the discharge slope 23 is 4%. The drive motor of the agitator 22 is embedded in the discharge slope 23. The discharge slope 23 is inclined towards the auger trough, which gradually guides and gathers the material accumulated on the discharge slope 23 to the lowest point, and then smoothly enters the auger trough, preparing for subsequent material conveying. During the material descent, the agitator 22 can continuously stir the material and break up any lumps that may form. The agitator 22 can not only prevent agglomeration, but also apply a certain pushing force to the material, assisting the material to slide down the discharge slope 23.

[0037] like Figure 3 and Figure 7As shown, the shock-absorbing protective layer 4 includes several shock-absorbing airbags 41 and several buffer spring columns 42. Several shock-absorbing airbags 41 are arranged between the outer surface of the inner storage chamber 2 and the inner wall of the outer protective chamber 1. The inner storage chamber 2 is connected to the outer protective chamber 1 through the buffer spring columns 42. The shock-absorbing airbags 41 are located on the bottom and four sides of the gap layer, and the buffer spring columns 42 are located on the four sides of the gap layer. The multiple buffer spring columns 42 restrict the lateral displacement of the inner storage chamber 2, prevent the inner storage chamber 2 from colliding with the outer protective chamber 1, and work with the shock-absorbing airbags 41 to alleviate the vibration of the inner storage chamber 2 during operation, evenly distribute the impact force generated by the material feeding, and make the double-layer material storage more stable.

[0038] When the outer protective compartment 1 is subjected to external impact, it can also initially absorb and disperse the impact energy, reducing the energy transferred to the inner storage compartment 2.

[0039] The shock-absorbing airbag 41 located in the gap layer can withstand the pressure generated by the vertical impact of material feeding in the storage chamber 2 and resist the impact force in the horizontal direction, preventing the storage chamber 2 from shaking or displacing in the horizontal and vertical directions. It can reduce the impact and vibration of the storage chamber 2 during material feeding in all directions, reduce the impact on the material in the storage chamber 2, protect the structure of the storage chamber 2, and stabilize the dual-chamber storage structure.

[0040] like Figure 1 and Figure 6 As shown, the cover 3 has a sealing etched line, a movable groove inside the cover 3, and a sliding groove. The sealing drive plate 6 is movably installed in the movable groove and moves within the movable groove inside the cover 3. The movable groove passes through the feed pipe 10, thereby sealing the feed pipe 10. The sealing etched line and the sliding groove provide a moving track and positioning reference for the sealing drive plate 6.

[0041] The sealing drive plate 6 includes a linear actuator 61 and a sealing baffle 62. The linear actuator 61 is detachably installed on the top surface of the cover 3. The telescopic end of the linear actuator 61 is connected to the sealing baffle 62. The sealing baffle 62 is movably installed in the movable groove. The telescopic end of the linear actuator 61 is located in the slide groove. The sealing lines are located on both sides of the slide groove. The linear actuator 61 is preferably a servo electric cylinder. The sealing line and the sealing baffle 62 are adapted to the movable groove.

[0042] One side of the movable groove has an opening that runs directly through the cover 3. A sealing block 9 is snapped into the opening. The sealing block 9 is also snapped into one side of the cover 3. The sealing block 9 is adapted to the movable groove. Simply open the sealing block 9 and start the linear drive 61 to push it. The length of the chute is the maximum extension distance of the linear drive 61. The blocking baffle 62 pushes out the powder to complete the cleaning. The powder entering the movable groove is cleaned in time to prevent the powder from accumulating and clumping in the movable groove. This prevents the blocking drive plate 6 from being obstructed or damaged due to powder blockage, thereby reducing the occurrence of equipment failure.

[0043] Working principle: The staff connects the modified powder discharge pipe to the feed pipe 10 of the cover 3, releases the blockage of the feed pipe 10 by the sealing drive plate 6, and starts feeding. The powder begins to be fed in large quantities. At this time, the powder is slowed down by the slowing slope 21. During the flow of the powder, a part of the powder falls through multiple discharge holes on the slowing slope 21 to reduce the vibration caused by the impact of the discharge. In addition, the shock-absorbing protective layer 4 effectively disperses and avoids the remaining vibration.

[0044] When it is necessary to block the feed pipe 10, the linear actuator 61 is started, and its telescopic end drives the blocking baffle 62 to move in the movable groove. The telescopic end of the linear actuator 61 moves along the slide to the blocking mark position, thus blocking the feed pipe 10 and preventing external impurities from entering the storage chamber 2, thereby ensuring the quality of the powder in the storage chamber 2.

[0045] During storage, the double-layer gap combined with the condensation partition 7 ensures the stability of the powder storage environment;

[0046] When discharging, the screw conveyor 5 starts, and together with the agitator 22 on the discharge slope 23, the powder is fed quickly, so that the powder is gathered in the screw conveyor trough, and then the powder in the screw conveyor trough is transported out.

[0047] All parts and equipment use conventional models in the existing technology. In addition, the circuit connection and communication connection adopt conventional connection methods in the existing technology, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
