Abstract
Description
Technical Field
[0001] This utility model relates to the field of atmospheric pressure silo technology, specifically to an atmospheric pressure container inlet with an anti-deviation flow guide cone. Background Technology
[0002] Atmospheric pressure silos have the same internal pressure as the external atmosphere, eliminating the need for complex pressure regulation systems. They are used to store materials that are not sensitive to pressure. In industries such as chemicals, grains, and feed, materials are typically fed into large atmospheric pressure silos through the top inlet.
[0003] Existing atmospheric pressure silos directly feed materials through a feed pipe, but the following problems exist: 1. Flow deviation phenomenon: When the concentrated material column impacts a fixed point, it causes the material to accumulate into a pointed cone shape, forming a "mouse hole." The material flows out preferentially from the central channel, disrupting the first-in, first-out principle and affecting the material storage period and mixing uniformity. 2. Material classification: During the falling process, coarse particles roll to the edge due to their large inertia, while fine particles are suspended in the central area, resulting in uneven particle size distribution. 3. Dust: The high-speed material column agitates the air inside the silo, carrying fine powder out and causing environmental pollution and material loss; 4. Impact wear: Long-term impact on fixed points causes localized wear on the bottom of the tank, shortening the equipment's lifespan.
[0004] Therefore, there is an urgent need for an atmospheric pressure vessel inlet with a flow-deflecting guide cone to prevent flow deviation. Utility Model Content
[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0006] Given the problems of flow deviation, material classification, dust emission, and impact wear in the existing technologies mentioned above.
[0007] To achieve the above objectives, this utility model provides the following technical solution: An atmospheric pressure vessel inlet with an anti-deviation guide cone includes a guide cone; a support assembly for connection and support; and an atmospheric pressure silo for storing materials. The guide cone includes: a fixed top ring fixed around the guide cone; and reinforcing ribs disposed on the surface of the guide cone; The support assembly includes: a support rod fixed around the fixed top ring; a telescopic sleeve plate sleeved on the outside of the support rod; and a fixed back plate fixed to the end of the telescopic sleeve plate, the fixed back plate being welded to the inner wall of the atmospheric pressure silo.
[0008] As a further embodiment of this utility model: the atmospheric pressure silo includes: a feed pipe welded to the top of the atmospheric pressure silo, and the guide cone is located below the feed pipe.
[0009] As a further embodiment of this utility model: the top of the guide cone and the vertical center line of the feed pipe are located on the same vertical line, and the distance between the top of the guide cone and the top of the feed pipe is 0.5-1m.
[0010] As a further embodiment of this utility model, the support assembly further includes: an adjustment hole formed inside the support rod; and a fixing screw passing through the telescopic sleeve plate.
[0011] As a further improvement of this utility model: the telescopic sleeve is detachably connected to the support rod by fixing screws, and the telescopic sleeve is slidably connected to the support rod.
[0012] As a further improvement of this utility model, the adjustment holes are evenly distributed at equal intervals along the surface of the support rod.
[0013] As a further embodiment of this utility model: the reinforcing ribs are evenly distributed at equal intervals along the surface of the guide cone, and the reinforcing ribs and the guide cone are integrally formed.
[0014] As a further improvement of this utility model, the cone angle of the guide cone is in the range of 60°-90°, and the diameter of the guide cone is in the range of 1.5-2 times the diameter of the feed pipe.
[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. The guide cone of this utility model is directly installed inside the atmospheric pressure silo, located directly below the feed inlet of the feed pipe. It transforms the traditional method of generating turbulence and random accumulation through point impact into a linear distribution that achieves laminar flow and uniform accumulation.
[0016] 2. This utility model achieves essential optimization of the material flow field through a minimalist mechanical design using a guide cone structure. It has low manufacturing costs, far lower than traditional rotary distributors, and can simultaneously solve four major problems: flow deviation, classification, wear, and dust. It has high versatility and is suitable for fixed silos of various granular and powdery materials. Attached Figure Description

[0019] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0020] 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. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.
[0022] Example 1: Please see Figures 1-4 This is the first embodiment of the present utility model. This embodiment provides an atmospheric pressure container inlet with an anti-deviation flow guide cone, including a flow guide cone 1; a support assembly 3 for connection and support; and an atmospheric pressure silo 5 for storing materials; The guide cone 1 includes: a fixed top ring 2 fixed around the guide cone 1; and a reinforcing rib 4 disposed on the surface of the guide cone 1; The support assembly 3 includes: a support rod 302 fixed around the fixed top ring 2; a telescopic sleeve 301 sleeved on the outside of the support rod 302; and a fixed back plate 304 fixed to the end of the telescopic sleeve 301, the fixed back plate 304 being welded to the inner wall of the atmospheric pressure silo 5.
[0023] Specifically, the atmospheric pressure silo 5 includes: a feed pipe 6 welded to the top of the atmospheric pressure silo 5, and a guide cone 1 located below the feed pipe 6.
[0024] Furthermore, the material of the guide cone 1 is selected according to the material characteristics, such as stainless steel, wear-resistant engineering plastics, ceramic lining plates, etc.
[0025] Specifically, the top of the guide cone 1 and the vertical center line of the feed pipe 6 are located on the same vertical line, and the distance between the top of the guide cone 1 and the top of the feed pipe 6 is 0.5-1m.
[0026] Furthermore, the tip of the guide cone 1 is aligned with the centerline of the feed inlet of the feed pipe 6 to prevent the material from flowing off course when it falls in.
[0027] Specifically, the support assembly 3 also includes: an adjustment hole 305 opened inside the support rod 302; and a fixing screw 303 passing through the telescopic sleeve 301.
[0028] Furthermore, the telescopic sleeve 301 slides outside the support rod 302 and can be adjusted according to the inner wall diameter of the atmospheric pressure silo 5, making it convenient to install the guide cone 1.
[0029] Specifically, the telescopic sleeve 301 is detachably connected to the support rod 302 via fixing screws 303, and the telescopic sleeve 301 and the support rod 302 are slidably connected.
[0030] Furthermore, the fixed back plate 304 can be directly welded to the inside of the atmospheric pressure silo 5, or it can be installed inside the atmospheric pressure silo 5 by bolts.
[0031] Specifically, the adjustment holes 305 are evenly distributed at equal intervals along the surface of the support rod 302.
[0032] Furthermore, the telescopic sleeve 301 and the support rod 302 are locked by inserting the fixing screw 303 into the adjustment hole 305.
[0033] In use, the guide cone 1 is installed directly below the feed inlet of the feed pipe 6 via the support assembly 3. The material falls vertically through the feed inlet of the feed pipe 6 and impacts the top of the guide cone 1. The material spreads radially along the cone surface of the guide cone 1, and the kinetic energy is converted into shear flow along the cone surface. Subsequently, the material detaches at the edge of the guide cone 1, forming a continuous annular thin material layer. The material curtain falls at an approximately uniform speed, forming a uniform material pile on the cross-section of the bin.
[0034] In summary, by setting the guide cone 1 and installing it directly inside the atmospheric pressure silo 5, located directly below the feed inlet of the feed pipe 6, the traditional method of generating turbulence and random accumulation due to point impact is transformed into a linear distribution to achieve laminar flow and uniform accumulation.
[0035] Example 2: Please see Figures 3-5 This is the second embodiment of the present utility model.
[0036] Specifically, the reinforcing ribs 4 are evenly distributed at equal intervals along the surface of the guide cone 1, and the reinforcing ribs 4 and the guide cone 1 are integrally formed.
[0037] Furthermore, the reinforcing rib 4 can strengthen the flow guide cone 1.
[0038] Specifically, the cone angle of the guide cone 1 is in the range of 60°-90°, and the diameter of the guide cone 1 is 1.5-2 times the diameter of the feed pipe 6.
[0039] Furthermore, taking a 2m diameter silo and a 200mm diameter feed pipe 6 as an example, the diameter of the guide cone 1 is 300–400mm, the cone tip of the guide cone 1 is 600mm from the feed inlet, the cone angle of the guide cone 1 is 75°, and its material is the same as that of the atmospheric pressure silo 5.
[0040] In use, the telescopic sleeve 301 moves along the axis of the support rod 302, which can adjust the overall length of the support assembly 3. The fixing screw 303 is inserted into the adjustment hole 305 to lock and fix the telescopic sleeve 301 and the support rod 302. Then the fixing back plate 304 is fixed inside the atmospheric pressure silo 5 to prevent the material from flowing into it.
[0041] In summary, the flow guide cone 1 structure achieves essential optimization of the material flow field through a minimalist mechanical design. It has low manufacturing costs, far lower than traditional rotary distributors, and can simultaneously solve four major problems: flow deviation, classification, wear, and dust. It is highly versatile and suitable for fixed silos of various granular and powdery materials.
