Description

Technical Field

[0001] The utility model belongs to the technical field of silo pump devices, and particularly relates to a silo pump sealing plate. Background Art

[0002] Traditional silo pumps use a honeycomb air distribution plate structure. Compressed air flows through the air silo into the air distribution plate, fluidizing the material. Traditional air distribution plates sandwich a filter cloth between two plates. Compressed air flows through the filter cloth, which can easily damage the filter cloth over time. Compressed air often picks up dust and impurities as it passes through the filter cloth, causing it to clog or break, reducing its service life.

[0003] When the filter cloth is damaged, compressed air directly flushes dust into it, accelerating the wear of the internal vulcanized plate. Under the existing design, the silo pump often needs to be disassembled weekly to replace the filter cloth, resulting in high maintenance labor and increased equipment maintenance complexity. Furthermore, the cost of replacing the vulcanized plate is high, at approximately 3,000 yuan per replacement, and the frequent replacement of spare parts results in wasted manpower and materials.

[0004] Therefore, a silo pump cloth sealing plate is proposed. Utility Model Content

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figure 1-3As shown, a silo pump sealing plate includes a bottom plate 1. The bottom plate 1 is the basic part of the sealing plate, provides overall structural support, and is connected to the inner wall of the silo pump. The bottom plate 1 is provided with a through hole 2. The through hole 2 is an air flow channel connected to the bottom plate 1, allowing compressed air to flow into the sealing plate and enter the silo pump, thereby fluidizing the material. The design of the through hole 2 allows the air flow to flow smoothly, avoids excessive concentration or unevenness of the air flow, and can effectively improve the fluidization effect of the material. An air collecting circle 3 is provided on the edge of the bottom plate 1. The air collecting circle 3 is used to concentrate the airflow, prevent the air from impacting the inner wall of the silo pump in large quantities during the distribution process, and control the flow direction of the compressed air. The air collecting circle 3 enhances the guiding effect of the airflow, makes the airflow distribution more uniform, improves the fluidization effect of the silo pump, and reduces equipment loss caused by uneven airflow.

[0023] Atop base plate 1 is a mid-panel 4, providing connection and support, enhancing overall structural stability and preventing loosening or damage to components caused by airflow. It effectively disperses airflow, reduces pressure concentration, and helps extend service life. Mid-panel 4 is provided with connection holes 5, which provide a certain degree of pressure relief. Airflow passes through these holes and exits through holes 2 in base plate 1, which are covered by mid-panel 4. A top plate 6 is located on top of mid-panel 4, providing resistance and dispersion to airflow, dispersing any compressed air that directly enters.

[0024] A bottom pillar 7 is set at the top center of the bottom plate 1 to connect to the middle plate 4. The bottom pillar 7 is located at the connecting part between the bottom plate 1 and the middle plate 4, and is used to support the middle plate 4 and ensure its stability. It can effectively share the impact pressure of the compressed air. At the same time, the air dispersed to the edge can pass through the through hole 2 of the bottom plate 1 through the space lifted by the bottom pillar 7. A top pillar 8 is set at the top center of the middle plate 4 to connect to the top plate 6. The top pillar 8 is located between the middle plate 4 and the top plate 6, and is used to stabilize the top plate 6 and maintain the overall structure of the cloth sealing plate. The top pillar 8 enhances the stability of the cloth sealing plate and ensures that the top plate 6 does not deform or loosen during long-term operation.

[0025] The following is a detailed description of the design of the above key components:

[0026] The bottom plate 1, middle plate 4, and top plate 6 are all circular plates, with their centers aligned. This circular structure ensures a more uniform and smoother airflow, avoids dead zones, and enhances overall structural stability. Aligning the centers of the bottom plate 1, middle plate 4, and top plate 6 uniformly distributes airflow from top to bottom, effectively reducing airflow refraction and turbulence and improving airflow efficiency.

[0027] The top edge of the inner wall of the air collecting ring 3 is cut at a 45° angle. The 45° angle guides the compressed air from the edge of the bottom plate 1 to the central area in a more concentrated manner, preventing the airflow from dispersing at the bottom edge, improving the airflow guidance efficiency and flow concentration, and enhancing the airflow control capability.

[0028] The bottom edge of the middle plate 4 is connected to the top of the base plate 1 via support columns 9. Six support columns 9 are arranged in a circular pattern around the center of the middle plate 4. The provision of support columns 9 effectively enhances the load-bearing capacity and stability of the middle plate 4, preventing bending or deformation caused by excessive airflow pressure. The even distribution of the six support columns 9 further disperses pressure, avoiding pressure concentration and thereby extending the service life and stability of the middle plate 4.

[0029] The top edges of the middle plate 4 and bottom plate 1 are cut downward at a 45° angle. This 45° angle effectively prevents gas from accumulating in the area between the middle plate 4 and bottom plate 1, promoting even airflow distribution and avoiding localized wear caused by excessive air pressure.

[0030] The diameter of the bottom plate 1 is larger than that of the middle plate 4, which in turn is larger than that of the top plate 6. The design of increasing radial dimensions from top to bottom further guides the airflow downward and disperses it, mitigating the impact of the airflow. This mitigation extends the service life of the filter cloth, and even if the filter cloth is damaged, it can still mitigate the impact of compressed air on the vulcanized plate, extending the life of the vulcanized plate and reducing the frequency of replacement.

[0031] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology. It will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
