Description

Technical Field

[0001] This invention relates to the field of gas-solid reaction experimental equipment technology, and in particular to a radial-circumferential partitioned particle receiving device at the bottom of a reaction tower. Background Technology

[0002] The flash furnace is the core equipment in the flash copper smelting process, and its structure includes a reaction tower, settling tank, and rising flue. During flash smelting, the structure of the concentrate nozzle directly determines the mixing effect between the material and the reaction gas flow, thus affecting smelting efficiency. Conducting gas-particle mixing tests directly in the industrial setting is not only limited by the high-temperature environment and production conditions within the furnace, but also presents challenges such as high testing costs, significant operational risks, and difficulties in data acquisition. Therefore, a cold-state similarity model experimental system was constructed to study particle dispersion behavior. A scaled-down model reaction tower, operating at ambient temperature and pressure, was used to reproduce the gas-solid two-phase flow characteristics within the industrial furnace.

[0003] When studying the gas-particle flow and particle dispersion behavior inside a flash reactor, it is necessary to obtain the particle deposition amount at different spatial locations at the bottom of the tower. This allows for the quantification of the radial and circumferential distribution characteristics of particles under different airflow conditions within the reaction tower. Furthermore, the influence of relevant airflow parameters on particle diffusion and deposition distribution within the reaction tower can be analyzed.

[0004] The existing experimental material receiving equipment has the following defects: the collection container has a simple structure, mostly adopting a fixed integrated silo, which cannot be disassembled and weighed independently, resulting in large experimental data errors; it lacks a fine zoning structure, cannot distinguish the particle deposition differences in the central, circumferential, and fan-shaped regions, and lacks multi-dimensional spatial data support.

[0005] Therefore, it is necessary to provide a new type of radial-circumferential partitioned particle receiving device at the bottom of a reaction tower to solve the above-mentioned technical problems. Summary of the Invention

[0006] The main objective of this invention is to provide a radial-circumferential partitioned particle receiving device at the bottom of a reaction tower, which aims to solve the technical problem of large experimental data errors caused by the lack of fine partitioning structure in existing receiving equipment.

[0007] To achieve the above objectives, the present invention proposes a radial-circumferential partitioned particle receiving device at the bottom of a reaction tower, comprising a receiving device, a lifting mechanism, and multiple receiving bins. The receiving device is used to connect to the bottom of the reaction tower and is divided into multiple receiving compartments of various sizes. The multiple receiving bins are detachably connected to the bottom of the multiple receiving compartments in a one-to-one correspondence. The receiving device is mounted on the lifting mechanism.

[0008] A further improvement of the radial-circumferential partitioned particle receiving device at the bottom of the reaction tower of the present invention is that the receiving device is divided into multiple annular regions from the inside to the outside in the radial direction, with the center of the cross section as the starting point, and the circular region is evenly divided into multiple equiangular fan-shaped regions along the circumferential direction with the center of the cross section as the vertex to form the receiving grid.

[0009] A further improvement of the radial-circumferential partitioned particle receiving device at the bottom of a reaction tower according to the present invention is that the receiving compartment includes a settling section and a converging particle chute, the particle chute being located at the bottom of the settling section.

[0010] A further improvement of the radial-circumferential partitioned particle receiving device at the bottom of a reaction tower according to the present invention is that the bottom of the particle chute is provided with a connecting section for connecting the receiving bucket.

[0011] A further improvement of the radial-circumferential partitioned particle receiving device at the bottom of the reaction tower of the present invention is that a chuck is detachably provided on the top of the receiving barrel, the chuck is clamped on the receiving barrel and connected to the connecting section by a clamp.

[0012] A further improvement of the radial-circumferential partitioned particle receiving device at the bottom of a reaction tower according to the present invention is that the plurality of receiving barrels include three receiving barrels of different diameters, respectively corresponding to the receiving compartments of three different diameters.

[0013] A further improvement of the radial-circumferential zoned particle receiving device at the bottom of a reaction tower according to the present invention is that the lifting mechanism includes a movable base, a lifting assembly, a support platform and a lifting drive, the support platform is located above the movable base, the lifting assembly and the lifting drive are both hinged between the movable base and the support platform, and the receiving device is installed on the support platform.

[0014] A further improvement of the radial-circumferential partitioned particle receiving device at the bottom of the reaction tower of the present invention is that the lifting assembly includes two scissor links, which are respectively located on both sides of the top surface of the movable base.

[0015] A further improvement of the radial-circumferential partitioned particle receiving device at the bottom of the reaction tower of the present invention is that the bottom of the movable base is provided with multiple integrated double-brake casters.

[0016] A further improvement of the radial-circumferential partitioned particle receiving device at the bottom of the reaction tower of the present invention is that the lifting drive component is a hydraulic rod.

[0017] The technical solution of the present invention has the following beneficial effects: This invention provides a radial-circumferential zoned particle receiving device at the bottom of a reaction tower. By detachably installing the receiving device and the receiving hopper, it allows for more flexible replacement of various collection containers such as the receiving hopper, sintered metal filter, dust collector bag, and plastic collection cylinder. Each receiving hopper is independently detachable, allowing for individual weighing of particles in each zone, effectively reducing experimental errors. It is adaptable to different experimental conditions, including ventilation, static settling, and rapid detection. In ventilation tests, a permeable sintered metal filter or dust collector bag is used instead of the receiving hopper, allowing the incoming airflow to penetrate the container and exit, while the particles are trapped. This is suitable for cold gas-solid two-phase flow tests in flash furnaces. In static settling tests, no high-speed airflow is used, allowing the study of particles settling freely into the receiving hopper under gravity. In rapid batch detection tests, disposable filter bags can be used instead of the receiving hopper. After the test, the entire device can be removed for weighing, eliminating the need for container cleaning and improving experimental efficiency. This avoids the problems of existing integrated fixed silos, which cannot be disassembled for weighing and have a limited range of collection devices. This invention avoids the shortcomings of existing integrated fixed silos that cannot be disassembled for weighing and have a single type of collection carrier.

[0018] This invention uses radially and circumferentially partitioned receiving grids to divide the material into independent central, circumferential, and fan-shaped collection areas. This allows for the simultaneous collection of particle deposition at different spatial locations, quantifying the radial and circumferential dispersion differences of the particles. Simultaneously, the settling sections and converging particle chutes within the partitions guide the particles, preventing accumulation and stagnation at partition corners and hopper inlets, thus preventing material blockage and overcoming the shortcomings of existing devices that lack precise partitioning.

[0019] This invention utilizes a lifting device with integrated double-brake casters to achieve overall horizontal movement, fixed position, and adjustable height of the heavy-duty receiving device. It can achieve precise alignment with the bottom of the reaction tower without manual lifting, avoiding material leakage and reducing operational difficulty and experimental interference.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0024] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0027] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0028] like Figures 1-13 As shown, the present invention proposes a radial-circumferential partitioned particle receiving device at the bottom of a reaction tower, including a receiving device 1, a lifting mechanism 3, and multiple receiving buckets 2. The receiving device 1 is used to connect to the bottom of the reaction tower. The receiving device 1 is divided into multiple receiving compartments 101 of various sizes. The multiple receiving buckets 2 are detachably connected to the bottom of the multiple receiving compartments 101 in a one-to-one correspondence. The receiving device 1 is installed on the lifting mechanism 3.

[0029] Specifically, the receiving device 1 is divided into multiple annular regions from the center of the cross section to the outside in a radial direction. The circular region is then evenly divided into multiple equiangular sector regions along the circumference, with the center of the cross section as the vertex, to form the receiving grid 101.

[0030] In this embodiment, in order to analyze the influence of airflow parameters on particle dispersion behavior in the reaction tower, a method of collecting particles in a certain area at the bottom of the reaction tower is used to obtain relevant data.

[0031] The designed receiving device 1 is installed at the bottom of the model reaction tower, and its cross-section is a circular area of ​​the same size as the reaction tower. To achieve quantitative analysis of the particle dispersion characteristics at the bottom of the reaction tower, the cross-section adopts a multi-dimensional division strategy of "radial + angular" to divide it into several sub-regions, as follows: ① Radial division: such as Figure 5 As shown, starting from the center of the cross-section, it is divided into 5 annular regions from the inside to the outside in the radial direction. The outer diameters of each region are 200 mm, 500 mm, 874 mm, 1188 mm and 1470 mm, respectively. They are labeled as Region I (center), Region II, Region III, Region IV and Region V from the inside to the outside.

[0032] ② Circumferential division: such as Figure 6 As shown, with the center of the cross-section as the vertex, the circular area is evenly divided into 12 equal-angle sector areas along the circumference, with the central angle of each area being 30°; starting from the area between 12 o'clock and 1 o'clock, the areas are numbered sequentially in a clockwise direction as area 1, 2, ..., 12.

[0033] like Figure 7 As shown, following the above division method, the section of the receiving device 1 is divided into 49 sub-regions (5 radial zones × 12 angular zones, where region I is not subdivided by angle). Each sub-region is identified using the format "radial region number - circumferential region number," for example, "I" represents the central region (without angular subdivision), and "Ⅳ-12" represents the sub-region at the intersection of the 4th radial ring and the 12th angular sector. This division strategy takes into account both the radial distribution hierarchy and the circumferential angular differences, providing a systematic spatial reference framework for subsequent analysis of particle dispersion behavior.

[0034] Preferably, such as Figure 4 , Figure 8 , Figure 9 The receiving compartment 101 includes a settling section 102 and a shrinking particle chute 103, which is located at the bottom of the settling section 102. The shrinking particle chute 103 can guide the particles, preventing them from accumulating and stagnating at the corners of the compartments and at the inlet of the hopper, thus preventing material blockage.

[0035] Furthermore, the bottom of the particle chute 103 is provided with a connecting section 104 for connecting the receiving bucket 2, so that the receiving bucket 2 and the receiving grid 101 can be installed in a one-to-one correspondence.

[0036] Preferably, such as Figures 10-12 As shown, the top of the receiving hopper 2 is detachably equipped with a chuck 201, which is snapped onto the receiving hopper and connected to the connecting section 104 by a clamp 202. In this embodiment, the receiving hopper 2 is made of sintered metal filter screen, and the clamp 202 is used to achieve quick assembly and disassembly connection with the receiving device 1, so as to accurately collect and analyze the particulate material that falls and tends to disperse in the reaction tower.

[0037] Specifically, the plurality of receiving hoppers 2 include three receiving hoppers 2 of different diameters, corresponding to the three different diameter receiving compartments 101. In this embodiment, three sizes of receiving hoppers 2 are used according to the area division of the receiving device 1 at the bottom of the reaction tower. These receiving hoppers 2 are all made of the aforementioned sintered metal filter screen material, and their material composition and structure are exactly the same. The only difference is in their geometric dimensions, in order to adapt to the installation requirements and material collection volume of different areas.

[0038] The specific allocation of the three diameter receiving buckets 2 is as follows: (a) Type 1: Used for particle collection in the central region (Region I); (b) Type 2: 12 in total, used for each sector sub-region of Region II; (c) Type 3: 36 in total, used for each sector sub-region of Region III, Region IV and Region V.

[0039] Through the above division, the particle samples falling into different cross-sectional areas of the receiving device 1 were collected independently, providing reliable sample data for subsequent analysis of the dispersion uniformity of particles in the reaction tower, as shown in Tables 1 and 2.

[0040] Table 1. Data collected in receiving bucket 2 during the experiment. In the experiment, receiving bucket 2 collected a total of 3140.3 g of particles, and the particle composition is shown in Table 2: Table 2. Particle percentage in receiving bucket 2 After weighing the receiving bucket 2 containing the particles, inverting the receiving bucket 2 can clean out most of the particles. The remaining particles in the bucket are cleaned by vibration.

[0041] Specifically, such as Figure 13As shown, the lifting mechanism 3 includes a movable base 301, a lifting assembly 302, a support platform 303, and a lifting drive component 304. The support platform 303 is located above the movable base 301. The lifting assembly 302 and the lifting drive component 304 are both hinged between the movable base 301 and the support platform 303. The receiving device 1 is installed on the support platform 303. The support platform 303 has mounting holes for installing the receiving device 1. The lifting mechanism 3 facilitates the lifting operation of the receiving device 1 (used to assemble 49 receiving buckets 2, with a total weight of 103.6 kg for all unfilled receiving buckets 2).

[0042] Furthermore, the lifting assembly 302 includes two scissor links, which are located on opposite sides of the top surface of the movable base 301. The scissor links are composed of multiple rods hinged in a scissor-like configuration, which is existing technology and will not be described in detail here.

[0043] Furthermore, the bottom of the mobile base 301 is provided with multiple integrated double-brake casters 306. In this embodiment, the mobile base 301 has a rectangular frame structure, and the number of integrated double-brake casters 306 is four, which are respectively installed at the four corners of the mobile base 301, enabling the device to move freely on the ground and fix its position; the circular support platform 303 is used to place the receiving bucket 2 to ensure precise docking with the bottom of the reaction tower.

[0044] In this embodiment, the lifting drive component 304 is a hydraulic rod. The pressure and flow rate of the hydraulic rod are adjusted via an electric control box 305 (existing technology, not described further), driving the hydraulic rod to extend and retract, which in turn drives the scissor lift linkage to rotate around the hinge point, achieving stable vertical lifting of the support platform 303. The operator can precisely adjust the lifting height via the electric controller to meet the docking requirements between the receiving device 1 and the bottom of the reaction tower. The lifting assembly 302, while bearing a large load, ensures ease of operation and stability.

[0045] The above description is only a preferred embodiment of the present invention and does not limit the scope of the present invention. All equivalent structural transformations made under the concept of the present invention using the description and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the protection scope of the present invention.
