Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to an anti-clogging dryer feeding structure and drying system. Background Technology

[0002] A dryer is a device that selectively adsorbs moisture from materials using the porous channels and cavities within a desiccant (such as silica gel or molecular sieves). The moisture is then carried away by heat exchange with a heat transfer medium and a carrier such as nitrogen, thus regenerating the desiccant. To prevent desiccant particles from entering the downstream system with the material flow, an isolation structure is usually installed at the feed inlet. The commonly used method in existing technologies is to install a screen around the feed pipe to physically isolate the desiccant from the material.

[0003] However, this structure has obvious drawbacks: Firstly, the limited number and small diameter of the feed pipe openings, coupled with the surrounding screen, result in a small actual material flow area. This leads to excessively high flow rates at the feed inlet during actual production, which can easily erode the desiccant. Furthermore, the desiccant at the feed end is often supersaturated with moisture, inevitably causing it to pulverize during repeated adsorption-desorption processes. This further clogs the screen, increases the pressure difference across the screen, and reduces the lifespan of both the desiccant and the screen, necessitating regular screen inspection and replacement. Secondly, for liquid-phase drying processes using a bottom-in, top-out method, the feed inlet is typically located at the bottom of the equipment and uses an insert-type pipe structure. Replacing the screen requires completely removing the inserted pipe, which easily causes the desiccant to scatter, making collection difficult. This not only increases desiccant loss but also introduces problems such as cumbersome replacement procedures and significant safety hazards. Moreover, since the desiccant's lifespan is usually longer than the screen's, frequent disassembly leads to resource waste. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-clogging dryer feeding structure to solve the technical problems of easy clogging of the feed inlet, frequent maintenance, and desiccant scattering when replacing the filter screen in traditional dryers.

[0005] In a first aspect, the anti-clogging dryer feeding structure provided by this utility model includes: a feeding pipe, a feeding buffer pipe, a desiccant barrier component, and an interception assembly; The desiccant barrier component is disposed in the feed channel of the dryer body. The desiccant barrier component has several holes and is used to support the desiccant bed above and block the desiccant. The feed buffer tube is located below the desiccant barrier component and is connected to the feed channel of the dryer body, and is detachably connected to the feed channel of the dryer body. The interception component is disposed inside the feed buffer pipe and is used to intercept the powdered particles that fall off from the desiccant bed. The feed pipe extends into the feed buffer pipe and is located below the interception component. The feed pipe is used to transport the fluid to be dried. The fluid to be dried passes through the interception component and the desiccant barrier component in sequence and enters the dryer body.

[0006] Furthermore, the pore size of the desiccant barrier component is smaller than the desiccant particle size.

[0007] Furthermore, the desiccant barrier is installed on a baffle block set on the inner wall of the feed channel of the dryer body.

[0008] Furthermore, the outer edge of the desiccant barrier component has a notch, through which the block can pass.

[0009] Furthermore, a handle is provided at the bottom of the desiccant barrier component.

[0010] Furthermore, the feed buffer pipe is connected to the feed channel of the dryer body through the first flange.

[0011] Furthermore, the interception component includes several layers of wire mesh units; Each layer of wire mesh unit contains wire mesh arranged in a cross pattern.

[0012] Furthermore, the feed structure of the anti-clogging dryer also includes a grid; The grid is disposed inside the feed buffer pipe and below the interception component.

[0013] Furthermore, the feed pipe is connected to the feed buffer pipe via a second flange.

[0014] Secondly, this utility model provides a drying system, including the aforementioned anti-clogging dryer feeding structure.

[0015] This utility model provides an anti-clogging dryer feeding structure that decouples the desiccant blocking function from the filtration interception function and adopts a graded arrangement and modular connection design, effectively solving the problems of easy clogging at the feed inlet, frequent maintenance, and desiccant scattering during filter replacement in traditional dryers. First, the desiccant blocking component is set inside the feed channel of the dryer body, with multiple holes that allow fluid to pass smoothly while supporting the upper desiccant bed. Compared to the traditional enclosed screen structure, this design significantly increases the material flow area, significantly reduces the fluid velocity at the same flow rate, reduces the scouring effect on the desiccant, and reduces pulverization caused by mechanical impact, thereby extending the desiccant's service life. Second, the interception component is set inside the feed buffer tube to trap pulverized particles falling from the desiccant bed, preventing them from entering the lower system and causing blockage or equipment damage; the feed buffer tube, as an independent cavity, has the functions of buffering and decelerating, and uniform flow distribution, further improving the system's operational stability. In addition, the feed buffer tube is detachably connected to the feed channel of the dryer body, which allows the interception component to be independently disassembled and replaced without removing the desiccant barrier components or disturbing the desiccant bed. This truly achieves the technical goal of "maintaining only the filter element without replacing the expensive desiccant", greatly reducing maintenance costs and material loss.

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0023] Firstly, such as Figure 1As shown, this embodiment provides an anti-clogging dryer feeding structure, including: a feeding pipe 100, a feeding buffer pipe 200, a desiccant barrier component 300, and an interception assembly 400; the desiccant barrier component 300 is disposed in the feeding channel 1 of the dryer body, and has several holes, which are used to support the desiccant bed above and block the desiccant; the feeding buffer pipe 200 is disposed below the desiccant barrier component 300 and is connected to the dryer body. The feed channel 1 of the dryer body is connected and detachably connected to the feed channel 1 of the dryer body; the interception component 400 is disposed in the feed buffer pipe 200 to intercept the powdered particles that fall off from the desiccant bed; the feed pipe 100 extends into the feed buffer pipe 200 and is disposed below the interception component 400. The feed pipe 100 is used to transport the fluid to be dried. The fluid to be dried passes through the interception component 400 and the desiccant barrier component 300 in sequence and enters the dryer body.

[0024] The anti-clogging dryer feeding structure provided in this embodiment decouples the desiccant blocking function from the filtration interception function and adopts a graded arrangement and modular connection design, effectively solving the problems of easy clogging at the feed inlet, frequent maintenance, and desiccant scattering when replacing the filter screen in traditional dryers. First, the desiccant blocking component 300 is set in the feed channel 1 of the dryer body, and has multiple holes, which can support the upper desiccant bed while allowing fluid to pass smoothly. Compared with the traditional encapsulated screen structure, this design significantly increases the material flow area, significantly reduces the fluid velocity at the same flow rate, reduces the scouring effect on the desiccant, reduces pulverization caused by mechanical impact, and thus extends the service life of the desiccant. Second, the interception component 400 is set inside the feed buffer pipe 200 to intercept pulverized particles that fall from the desiccant bed and prevent them from entering the lower system and causing blockage or equipment damage; while the feed buffer pipe 200, as an independent cavity, has the functions of buffering and decelerating, and uniform flow distribution, further improving the operational stability of the system. In addition, the feed buffer pipe 200 is detachably connected to the feed channel 1 of the dryer body, which allows the interception component 400 to be independently disassembled and replaced without removing the desiccant barrier component 300 or disturbing the desiccant bed. This truly achieves the technical goal of "maintaining only the filter element without replacing the expensive desiccant", greatly reducing maintenance costs and material loss.

[0025] The anti-clogging dryer feeding structure provided in this embodiment optimizes the layout of key components in the feeding path, achieving a large flow area and low flow rate feeding, and supports independent installation and removal of filter elements, thereby significantly improving the equipment's operational stability and maintenance convenience. This embodiment addresses the shortcomings of easy clogging of the screen at the dryer's feed inlet, resulting in short and frequent replacement and maintenance cycles, high maintenance difficulty, and high maintenance costs. By improving the dryer's feed inlet structure, it fundamentally solves the screen clogging problem.

[0026] In an optional embodiment, the pore size of the desiccant barrier component 300 is smaller than the desiccant particle size.

[0027] Specifically, such as Figures 2-3 As shown, the desiccant barrier component 300 is configured as a baffle, serving as both a carrier and separator for the desiccant, and is located inside the feed channel 1 of the dryer body. The baffle has multiple evenly spaced holes, the diameter of which is smaller than the particle size of the desiccant. This allows the baffle to hold the desiccant, preventing it from falling out, and effectively preventing the upper desiccant bed from falling while allowing fluid to pass through. Compared to the original structure, its opening area is larger, resulting in a larger flow area. At the same volumetric flow rate, this reduces the fluid velocity, preventing the fluid from eroding the desiccant and causing it to pulverize. This effectively improves the desiccant's service life. Since this hole size eliminates the need for a screen covering, and the number of screens is increased compared to the inserted feed pipe type, the material flow area is effectively increased, thereby reducing the flow velocity and effectively preventing the desiccant from being eroded by the fluid, thus increasing the desiccant's service life. To further explain, due to the large number of holes and the large total open area, compared with the traditional small-aperture screen structure, the material flow cross section is significantly increased. Under the same flow conditions, the fluid velocity is greatly reduced, which reduces the scouring effect on the desiccant in the feeding area. This helps to reduce the pulverization of the desiccant caused by mechanical impact and extends its service life.

[0028] Optionally, the baffle is a circular structure, which is horizontally arranged across the feed channel 1 of the dryer body and is positioned and supported by the support structure provided on the inner wall of the feed channel 1.

[0029] In an optional embodiment, the desiccant barrier 300 is mounted on a baffle 11 provided on the inner wall of the feed channel 1 of the dryer body.

[0030] In an optional embodiment, the outer edge of the desiccant barrier member 300 is provided with a notch 310, through which the block 11 can pass.

[0031] Specifically, such as Figure 2 and Figure 3As shown, the outer edge of the baffle has a notch 310 (i.e., a groove recessed towards the baffle's own axis). During installation, the baffle can be inserted into the feed channel 1 of the dryer body, aligning the notch 310 with the stop block 11 on the inner wall. After it is fully inserted, it is rotated so that the stop block 11 is located below the baffle, thus achieving fixation. It should be noted that the design requirement for the notch 310 is that the opening size should meet the strength requirements but not be too large to prevent the desiccant from falling out of the notch.

[0032] In an optional embodiment, the edge of the baffle may be evenly provided with three notches 310, and correspondingly, three blocks 11 are welded on the inner wall of the feed channel 1 of the dryer body. During installation, the baffle is inserted, its groove is aligned with the block 11 and slid into place, and then rotated at a certain angle so that the block 11 is located below the groove, thereby supporting the entire baffle and achieving its stable fixation in the feed channel 1. This snap-fit ​​structure can not only reliably support the weight of the upper desiccant bed, but also facilitates the removal of the entire baffle when the desiccant needs to be replaced, avoiding disorderly scattering of the desiccant, improving the safety and controllability of maintenance. At the same time, it can also effectively support the desiccant when replacing the lower structured packing or performing equipment maintenance, preventing it from falling from the bottom of the feed channel 1 into the buffer area or pipe, avoiding material loss and system blockage.

[0033] When the desiccant needs to be replaced, the operator can rotate the baffle to realign the groove with the gap between the baffles 11, and then remove it smoothly. This makes the desiccant release process controllable and facilitates the orderly discharge and centralized collection of waste desiccant.

[0034] In addition, the dryer body is typically filled with tons of desiccant. After the baffle is installed, the weight of the upper desiccant bed can suppress the displacement of the baffle during operation. To further improve the stability of the system operation, optionally, to improve the installation stability of the baffle in the feed channel 1 of the dryer body and prevent it from displacing due to fluid impact or equipment vibration during operation, an upper protrusion 12 is also provided on the inner wall of the feed channel 1 of the dryer body. The upper protrusion 12 is located above the baffle and extends radially inward along the feed channel 1 of the dryer body, forming a limiting fit with the outer edge of the baffle to restrict the upward movement of the baffle in the axial direction, thereby achieving dual positioning of the baffle: the lower part is supported by the support block 11, and the upper part is limited by the upper protrusion 12, which significantly enhances the reliability and safety of the overall structure.

[0035] In an optional embodiment, to further improve operational convenience, a handle 320, such as a T-shaped round steel handle 320, is provided at the bottom center of the desiccant barrier component 300. This handle 320 is a metal component welded to the center of the baffle and can be used to assist in lifting, rotating, and positioning the baffle, significantly optimizing its installation and disassembly process and improving the safety and efficiency of maintenance operations. Since desiccants inevitably pulverize during long-term water absorption and drying, they need to be replaced periodically after reaching their service life. By installing the handle 320, it is easy to remove the baffle when replacing the desiccant, and the baffle can support the desiccant, preventing it from scattering, effectively optimizing the desiccant replacement process.

[0036] Specifically, by installing a round steel handle 320 on the baffle, along with the baffle and snap-fit ​​structure, a detachable load-bearing system is formed. Operators can smoothly lift or lower the baffle using the handle 320, ensuring that the desiccant remains under control during replacement and preventing disorderly collapse and scattering due to sudden loss of support.

[0037] In an optional embodiment, the feed buffer pipe 200 is connected to the feed channel 1 of the dryer body via a first flange 600.

[0038] Specifically, the feed buffer pipe 200 is located below the baffle and communicates with the feed channel 1 of the dryer body to guide the fluid to be dried into the dryer. The feed buffer pipe 200 and the dryer body are detachably connected. In one embodiment, the two are connected by a flange, which facilitates the removal of the feed buffer pipe 200 as a whole during maintenance without disturbing the baffle and desiccant bed above.

[0039] In an optional embodiment, the interception component 400 includes several layers of wire mesh units; each layer of wire mesh unit is provided with wire mesh arranged in a cross pattern.

[0040] Specifically, the interception component 400 is disposed inside the feed buffer pipe 200. As an interception component, 400 is used to trap powdery particles detached from the desiccant bed, preventing them from entering the downstream system with the fluid and causing blockage or equipment damage. In an optional embodiment, the interception component 400 includes multiple stacked wire mesh units (also referred to as wire mesh structured packing), with the wire mesh in each unit intersecting and fixed in a cross shape. This design ensures sufficient filtration area and enhances structural rigidity, preventing deformation or breakage of individual wire mesh sheets. The multi-layered wire mesh units are arranged sequentially along the axial direction, further improving the interception capacity for fine particles. Simultaneously, the wire mesh mesh count is greater than 200 meshes, greatly increasing the flow area, preventing wire mesh blockage, effectively reducing the pressure difference across the wire mesh, and increasing the service life of the wire mesh.

[0041] Specifically, such as Figure 1 As shown, the interception assembly 400 includes a first wire mesh unit 410 and a second wire mesh unit 420 stacked together, with the wire mesh in both the first wire mesh unit 410 and the second wire mesh unit 420 fixed in a cross shape. The wire mesh has a high mesh count and numerous pores, resulting in a large flow area. The powdered desiccant is less likely to clog the wire mesh, effectively ensuring material flow and preventing clogging like other screens. This further reduces the pressure difference across the wire mesh, preventing damage due to high pressure differential and extending the service life of the wire mesh.

[0042] To further explain, the interception component 400 not only intercepts powdered desiccant particles during the drying operation phase, preventing desiccant powder from entering the material feeding system, but more importantly, during dryer regeneration or equipment maintenance, when liquid material needs to be discharged from the bottom outlet, the wire mesh acts as a critical isolation barrier, effectively preventing upper desiccant powder from flowing out with the liquid, ensuring reliable separation of material and desiccant. Furthermore, if bottom feeding is interrupted, the liquid phase may flow backward from the lower outlet due to gravity. In this case, the wire mesh still maintains its desiccant-blocking function, preventing desiccant leakage into the upstream feeding system, ensuring system safety and media purity.

[0043] In an optional embodiment, a grid 500 is also included; the grid 500 is disposed inside the feed buffer pipe 200 and below the interception assembly 400.

[0044] Specifically, to ensure the stability of the wire mesh during operation, a grid 500 is also provided. The grid 500 is installed inside the feed buffer pipe 200 and located below the wire mesh. It is used to support and fix the wire mesh. The wire mesh structure is fixed in the pipe by supporting the grid 500 to prevent it from shifting or collapsing under high flow rate or pressure fluctuations.

[0045] In an optional embodiment, the feed pipe 100 is connected to the feed buffer pipe 200 via a second flange 700.

[0046] Specifically, the feed pipe 100 is used to transport the fluid to be dried, and one end of it extends into and is connected to the feed buffer pipe 200. In an optional embodiment, the feed pipe 100 and the feed buffer pipe 200 are also connected by a flange to achieve quick disassembly and assembly, which facilitates cleaning or replacement of the feed buffer pipe 200 and its internal components.

[0047] In the anti-clogging dryer feeding structure provided in this embodiment, the fluid to be dried is introduced from the outside. The liquid material enters the feed buffer pipe 200 through the feed pipe 100 in a bottom-in, top-out manner. Subsequently, the fluid flows upward through the holes in the baffle and enters the desiccant bed inside the dryer body to complete the moisture adsorption process. The entire flow path achieves orderly control of "graded buffering-uniform material distribution," effectively avoiding local high-speed impacts and pressure differential accumulation.

[0048] Further explanation: This embodiment addresses the problems of easy clogging, frequent replacement, complex maintenance, and easy powdering and scattering of desiccant in the feed inlet of existing dryers by proposing a novel anti-clogging feed structure. This structure abandons the traditional method of covering the feed pipe with the screen, instead adding a graded barrier structure composed of baffles and wire mesh in the feed channel 1. The baffles are located within the feed channel 1 of the dryer body and have multiple through holes, the diameter of which is slightly smaller than the particle size of the desiccant. The large number of through holes results in a large total flow area. This design significantly reduces the flow velocity of the material while ensuring effective desiccant isolation, reducing the scouring effect on the desiccant bed in the feed area, thereby reducing desiccant powdering caused by mechanical impact, improving the service life of the desiccant, and enhancing the operational stability of the adsorption process.

[0049] Furthermore, to effectively retain pulverized particles, a wire mesh is installed below the baffle as an interception component 400. The wire mesh employs a high-mesh, structured packing, featuring a large flow area and high filtration efficiency. Compared to traditional screens, this wire mesh is less prone to clogging by pulverized matter, exhibits slower pressure differential growth, and has a longer service life. Simultaneously, it can be independently replaced without affecting the desiccant bed, significantly reducing maintenance costs.

[0050] Furthermore, addressing the issue of desiccant scattering during desiccant replacement in existing technologies, this embodiment incorporates a handle 320 on the baffle, facilitating controlled disassembly and assembly by operators. This design enables orderly management of the desiccant replacement process, preventing material loss and on-site safety hazards, and significantly improving equipment maintainability and operational safety.

[0051] This embodiment has the following advantages: 1. This structure has a large material flow area. After passing through the wire mesh packing and baffles in the 200mm feed buffer pipe, the material enters the dryer, which fundamentally solves the problem of large pressure difference on both sides of the screen, improves anti-clogging ability, and greatly reduces maintenance frequency. 2. This structure reduces the erosion of the desiccant by materials, thus extending the desiccant's service life; 3. This structure can solve the problem that the desiccant must be replaced when the filter screen of the lower head feed dryer is replaced, so as to realize the replacement of the filter screen separately and reduce maintenance costs; 4. This structure can solve the problem of desiccant not being collected when replacing the filter or removing the desiccant, improving the convenience and safety of maintenance and reducing the workload of maintenance.

[0052] Secondly, this embodiment provides a drying system, including an anti-clogging dryer feed structure. Since the technical effects of the drying system provided in this embodiment are the same as those of the anti-clogging dryer feed structure provided in the above embodiments, they will not be repeated here.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
