Abstract
Description
Technical Field
[0001] This application relates to the technical field of conical bottom silos, specifically a porous air-blowing fluidized conical bottom silo. Background Art
[0002] A conical bottom silo is a device used for storing and processing granular materials, and is widely used in industries such as chemical engineering, food, pharmaceuticals, and mining. Its main feature is that the bottom is designed in a conical shape, which can effectively promote the flow and discharge of materials.
[0003] The bottom of the conical bottom silo is conical. This design helps the materials to flow downward under the action of gravity. However, the materials at the upper end of the discharge port are prone to arching and causing discharge blockage under this conical design. Currently, in the prior art, an arch-breaking motor and a stirring paddle type arch-breaking device are used to perform arch-breaking treatment on the conical bottom silo. Generally, the above-mentioned existing arch breakers can only perform local arch-breaking on the upper part of the discharge port. When arching forms on the side, although the materials will not be blocked as a whole, it will still affect the falling speed of the materials and the production progress. For this reason, a porous air-blowing fluidized conical bottom silo is proposed to solve the above-mentioned problems. Utility Model Content
[0004] In view of the deficiencies of the prior art, this application provides a porous air-blowing fluidized conical bottom silo, which has the advantages of multi-directional commutation arch-breaking and ensuring smooth discharge.
[0005] To achieve the above object, this application provides the following technical solution: A porous air-blowing fluidized conical bottom silo, including a conical bottom silo outer wall and a conical bottom silo inner wall that are fixedly connected to each other. The outside of the conical bottom silo outer wall is communicated with an annular air-blowing pipe through a plurality of connecting pipes. Ventilation holes are penetrated and opened on the conical bottom silo inner wall, and a pressurization structure is arranged on the outer side of the conical bottom silo inner wall;
[0006] The pressurization structure includes an air hood fixedly installed outside the conical bottom silo inner wall, a pressurization pipe fixed on the inner wall of the air hood, and a pressing plate located inside the pressurization pipe.
[0007] Further, connection flanges are welded to the tops of both the conical bottom silo outer wall and the conical bottom silo inner wall. The size of the conical bottom silo outer wall is larger than that of the conical bottom silo inner wall. A sealing gasket is added between the two connection flanges on the conical bottom silo outer wall and the conical bottom silo inner wall for sealed connection.
[0008] Further, a discharge port is welded to the bottom of the conical bottom silo outer wall, and a detachable sealing block that closely fits on the inner wall of the discharge port is fixedly installed at the bottom end of the conical bottom silo inner wall.
[0009] Further, the detachable sealing block is selected to be circular, and a bottom sealing gasket is further provided at the bottom of the discharge port.
[0010] Furthermore, the annular air blowing pipe is a circular pipe, several connecting pipes are continuously arranged inside the annular air blowing pipe, and the outside of the annular air blowing pipe is directly connected to an air pump.
[0011] Furthermore, an air supply hole is penetrated and opened at one end of the air hood away from the ventilation hole, and the air supply hole corresponds to the ventilation hole.
[0012] Furthermore, the pressurizing pipe is located outside the air supply hole, a limiting ring is fixedly installed on the inner wall of the pressurizing pipe, and the pressing plate is closely attached to the limiting ring.
[0013] Furthermore, the cross section of the limiting ring is semi-circular. The limiting ring includes a sealing ring and a blocking ring, which are annular and distributed up and down on the inner wall of the pressurizing pipe. The diameter of the pressing plate is smaller than the inner diameter of the pressurizing pipe and larger than the inner diameter of the blocking ring.
[0014] Furthermore, a bracket located inside the air hood is fixedly installed on the outer wall of the inner wall of the conical bottom bin, and a return spring is fixedly installed between the bracket and the pressing plate.
[0015] Compared with the prior art, the technical solution of the present application has the following beneficial effects:
[0016] For this porous air-blowing fluidized conical bottom bin, a cavity is formed between the outer wall and the inner wall of the conical bottom bin, and hot air is continuously introduced into the cavity through the annular air blowing pipe, so that the upper piled materials in the conical bottom bin can be broken arch in a 360° circumferential direction, ensuring smooth discharging. At the same time, the conical bottom bin is kept dry and not easily adhered and arched. The hot air blown in breaks the arch and reduces the humidity in the conical bottom bin, avoiding moisture and deterioration of the materials. By setting a pressurizing structure, the blown hot air has a certain impact ability, effectively dealing with the arching phenomenon. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0023] Please refer to Figures 1 to 4 , the porous air blowing type fluidized conical bottom bin in this embodiment includes an outer wall 1 of the conical bottom bin and an inner wall 2 of the conical bottom bin that are fixedly connected to each other. Among them, connecting flanges 3 are welded to the tops of both the outer wall 1 of the conical bottom bin and the inner wall 2 of the conical bottom bin. Flange connection is carried out through two connecting flanges 3 with the same outer diameter and different inner diameters, so that a cavity is formed between the inner wall 2 of the conical bottom bin and the outer wall 1 of the conical bottom bin and they are connected to each other.
[0024] It should be added that both the outer wall 1 of the conical bottom bin and the inner wall 2 of the conical bottom bin are rolled into a conical shape by iron plates or stainless steel plates, and the size of the outer wall 1 of the conical bottom bin is larger than that of the inner wall 2 of the conical bottom bin, so as to form a conical cavity between the outer wall 1 of the conical bottom bin and the inner wall 2 of the conical bottom bin.
[0025] Preferably, a sealing gasket 4 is also added between the two connecting flanges 3 on the outer wall 1 of the conical bottom bin and the inner wall 2 of the conical bottom bin for sealed connection.
[0026] A discharge port 5 is welded to the bottom of the outer wall 1 of the conical bottom bin, and a removable sealing block 6 that closely fits on the inner wall of the discharge port 5 is fixedly installed at the bottom end of the inner wall 2 of the conical bottom bin. Among them, the removable sealing block 6 is selected as a circular ring to close the bottom of the cavity formed between the outer wall 1 of the conical bottom bin and the inner wall 2 of the conical bottom bin, and can also be used to clean the materials entering the cavity from the lower port. A bottom sealing gasket 7 is also provided at the bottom of the discharge port 5 to enhance the sealing of the connection.
[0027] In this embodiment, the outside of the outer wall 1 of the conical bottom bin is connected to an annular air blowing pipe 8 through a plurality of connecting pipes 9. The annular air blowing pipe 8 is a circular pipe, and a plurality of connecting pipes 9 are continuously arranged on the inner side of the annular air blowing pipe 8, and the outside of the annular air blowing pipe 8 is directly connected to an air pump.
[0028] With such a design, the gas blown into the cavity between the outer wall 1 of the conical bottom bin and the inner wall 2 of the conical bottom bin by the air pump can be evenly fed and distributed.
[0029] It should be noted that ventilation holes 10 are penetrated through the inner wall 2 of the conical bottom bin. The ventilation holes 10 surround the inner wall 2 of the conical bottom bin and can evenly blow out the gas in the cavity from the pores, so as to realize the gas arch breaking of the materials on the inner wall 2 of the conical bottom bin.
[0030] In this embodiment, a pressurizing structure is arranged on the outer side of the inner wall 2 of the conical bottom bin. The pressurizing structure is located in the cavity between the inner wall 2 of the conical bottom bin and the outer wall 1 of the conical bottom bin, and a pressurizing structure is arranged at each ventilation hole 10.
[0031] In this embodiment, the pressurizing structure includes an air hood 11 fixedly installed outside the inner wall 2 of the conical bottom bin, a pressurizing pipe 13 fixed on the inner wall of the air hood 11, and a pressing plate 14 located in the pressurizing pipe 13.
[0032] Among them, an air supply hole 12 is penetrated through one end of the air hood 11 far from the ventilation hole 10. The air supply hole 12 corresponds to the ventilation hole 10 and is used to communicate the inside and outside of the inner wall 2 of the conical bottom bin with each other.
[0033] The pressurizing pipe 13 is located outside the air supply hole 12. The pressurizing pipe 13 is a circular pipe penetrating up and down. The pressurizing pipe 13 can prevent the direct connection between the air supply hole 12 and the ventilation hole 10 and form a conditional blockage.
[0034] It should be noted that a limiting ring 15 is also fixedly installed on the inner wall of the pressurizing pipe 13, and the pressing plate 14 is closely attached to the limiting ring 15.
[0035] Specifically, the cross section of the limiting ring 15 is semicircular. The limiting ring 15 includes a sealing ring 152 and a blocking ring 151, which are annular and distributed up and down on the inner wall of the pressurizing pipe 13. The limiting ring 15 is made of rubber or silica gel. The diameter of the pressing plate 14 is smaller than the inner diameter of the pressurizing pipe 13 and larger than the inner diameter of the blocking ring 151.
[0036] Preferably, the blocking ring is located at one end of the pressurizing pipe 13 far from the air supply hole 12, the sealing ring is located at one end of the pressurizing pipe 13 close to the air supply hole 12, and the pressing plate 14 is located between the sealing ring 152 and the blocking ring 151.
[0037] With such a design, when the pressing plate 14 needs to cross over the blocking ring 151, it is necessary to squeeze the blocking ring 151 to make it deformed. Therefore, to a certain extent, the inner cavity of the pressurizing pipe 13 can be in a sealed state, and a certain air pressure is required to push open the pressing plate 14.
[0038] To reset the pressing plate 14, a bracket 16 located within the air hood 11 is fixedly installed on the outer wall of the inner wall 2 of the conical bottom bin in this embodiment. A reset spring 17 is fixedly installed between the bracket 16 and the pressing plate 14. One end of the reset spring 17 is fixedly connected to the pressing plate 14, and the other end of the reset spring 17 is fixedly connected to the bracket 16. The spring force of the reset spring 17 should be selected according to the pressure difference of the actual blocking ring 151, so that under the push of the reset spring 17, the pressing plate 14 can cross over the blocking ring 151 and abut against the sealing ring 152 to close the pressurizing pipe 13 under normal conditions.
[0039] The working principle of the above embodiment is as follows:
[0040] While discharging materials using the conical bottom bin, control an external air pump to send hot air through the annular air blowing pipe 8 and the connecting pipe 9 into the cavity between the outer wall 1 of the conical bottom bin and the inner wall 2 of the conical bottom bin. The gas accumulates in the cavity. Since the cavity and the ventilation hole 10 are blocked by the air hood 11 and are connected through the air supply hole 12, the gas can enter the inner wall of the pressurizing pipe 13 from the air supply hole 12. Subject to the pressure of the limiting ring 15 and the reset spring 17 on the pressing plate 14, the air pressure accumulates and increases in the cavity. When the air pressure reaches a certain value, it can push open the pressing plate 14 so that the gas rushes into the inner wall 2 of the conical bottom bin from the ventilation hole 10, realizing arch breaking in the inner wall 2 of the conical bottom bin;
[0041] After the first arch breaking, the air pressure in the cavity drops. Under the push of the reset spring 17, the pressing plate 14 closes again and repeats the above process. Due to the blocking of the bracket 16, the entry of materials from the inner wall 2 of the conical bottom bin into the cavity can be reduced.
[0042] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
