Description

Technical Field

[0001] This invention relates to the field of material conveying technology, and more particularly to an apparatus and its operating method for conveying solid materials using fluid. Background Technology

[0002] A company's main energy plant has power generation and water supply processes that require primary and secondary demineralized water. The water treatment equipment currently in use includes cation and anion beds, mixed beds, and reverse osmosis. Since the cation and anion beds and mixed beds are filled with cation and anion resins, which are solid particulate materials with an average particle diameter of 600-800um and a fine particle content of <0.425mm:0.5%max.

[0003] Anion and cation exchange resins contain a certain amount of water, which should be preserved as much as possible during transportation and storage. If the resin dehydrates during storage, it should first be soaked in concentrated saline solution (-10%), and then gradually diluted. It should not be placed directly in water to avoid the resin from expanding rapidly and breaking.

[0004] During long-term storage, strong resins should be converted to their salt form, while weak resins can be converted to their corresponding hydrogen or free basic forms, or simply to their salt form, and then soaked in clean water. During storage or transportation, the resin should be maintained at a temperature of 5-40°C to avoid excessive cold or heat, which could affect its quality. If insulation equipment is unavailable in winter, the resin can be stored in a saline solution, the temperature of which can be adjusted according to the ambient temperature.

[0005] Due to the properties of the resin, it was originally necessary to manually carry the bags one by one to the manhole and pour them into the tank when filling it into the yin-yang bed storage tank. Because the filling manhole was small, the manual filling was inefficient and affected the water production output to varying degrees, thus impacting downstream production users. Summary of the Invention

[0006] In response to the aforementioned technical problem, an apparatus for conveying solid materials using fluid and a method for operating the same are provided.

[0007] The technical means employed in this invention are as follows:

[0008] An apparatus for conveying solid materials using fluid includes: a feeding assembly, a conveying pipeline, a moving assembly, and a water and air supply assembly. The feeding assembly is mounted on the moving assembly and includes a hopper and a conveying component. The top of the hopper has a feed inlet, and the bottom is connected to the conveying pipeline via the conveying component. Solid materials are poured into the hopper and conveyed into the conveying pipeline. One end of the conveying pipeline is connected to the water and air supply assembly, and the other end is connected to a resin storage tank. The water and air supply assembly is used to supply fluidizing water or fluidizing air to the conveying pipeline.

[0009] Furthermore, the conveying pipeline includes a first pipeline and a second pipeline connected by a flange structure, and the conveying component is connected to the first pipeline and is close to the second pipeline.

[0010] Furthermore, the conveying component includes a discharge port at the bottom of the hopper and a short pipe connected to the discharge port, the short pipe forming a three-way structure with the first pipeline.

[0011] Furthermore, the first pipeline has an inlet at the end furthest from the second pipeline, which is connected to the water and air supply components. The second pipeline has an outlet at the end furthest from the first pipeline, which is an outlet flange, and the outlet flange is sealed to the inlet flange of the resin storage tank.

[0012] Furthermore, the water and air supply assembly includes a water supply device and an air supply device, which are connected to the inlet via separate pipelines. A water pump is installed on the pipeline connecting the water supply device and the inlet.

[0013] Furthermore, the second pipeline is a delivery hose.

[0014] Furthermore, the moving component includes a base, multiple columns, and multiple wheels. The multiple wheels are installed at the bottom of the base, the bottom ends of the multiple columns are welded to the upper surface of the base, and the top ends of the multiple columns are welded to the outer wall of the hopper.

[0015] Furthermore, a conveyor is provided on one side of the hopper, and the outlet side of the conveyor is located directly above the hopper.

[0016] The present invention also provides a method for operating an apparatus for transporting solid materials using fluid, comprising the following steps: The material is fed into the hopper through the inlet, and then falls into the conveying pipeline through the conveying component. Under the power of the fluidizing water or air supplied to the conveying pipeline by the water and air supply components, the material at the outlet of the conveying component is fluidized, making the material looser and conveyed to the outlet. This prevents the material from being blocked or jammed at the outlet. Furthermore, under the power of the fluidizing water or air, the material in the conveying pipeline is conveyed downstream in a timely and stable manner, which is conducive to the stable delivery of the material to the resin storage tank.

[0017] Compared with the prior art, the present invention has the following advantages: 1. The device and its working method for conveying solid materials using fluid provided by this invention realize the automated conveying and filling of small particulate solid materials such as resin. The device adopts a modular structure, which combines mobility and ease of operation, and can significantly improve the material transfer efficiency. The material transmission path is optimized, and the loss of resin during the filling process is effectively reduced through the closed conveying system. The material utilization rate is increased by more than 30% compared with the traditional method. The metering and semi-automated operation of the conveying process are realized, which not only reduces the intensity of manual intervention by 60%, but also ensures the stability of the production process.

[0018] 2. The device and its working method for conveying solid materials using fluid provided by the present invention conveys materials into a conveying pipeline through a hopper and conveying components, and provides fluidizing water or fluidizing air into the conveying pipeline through a water supply and air supply assembly. Under the action of this power, the material at the outlet of the conveying components can be fluidized, making the material looser and conveyed to the discharge port, thereby preventing the material from being blocked or jammed at the discharge port. At the same time, under the power of the fluidizing water or fluidizing air, the material in the conveying pipeline can be conveyed downstream in a timely and stable manner, which is beneficial to the stable delivery of the material to the resin storage tank.

[0019] Based on the above reasons, this invention can be widely applied in fields such as solid material conveying. Attached Figure Description

Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0028] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description.

[0031] Example 1 Traditional manual filling methods for smooth, small resin particles present significant technical drawbacks: production data shows that manually filling 20 tons of resin requires two operators and 16 hours, posing safety hazards. Furthermore, the long filling cycle and high labor intensity can lead to uneven resin distribution, affecting subsequent water quality. Manual operation also carries the risk of foreign objects such as plastic bags and gloves being introduced into the resin storage tank, potentially damaging the resin's function. Frequent high-altitude handling is not only labor-intensive and time-consuming (averaging over 48 hours of reduced production recovery time), but also poses safety risks such as falls from heights. Technical analysis reveals that the working environment of resin has hydrophilic characteristics, providing a new technical approach to solving this problem.

[0032] 1. Technical feasibility: The project is based on a solid theoretical and practical foundation. The research methods used are all proven in practice and have corresponding achievements and practical equipment, demonstrating a solid practical foundation.

[0033] 2. Economic feasibility: The implementation of this project can significantly shorten the resin filling time, reduce downtime, and improve production stability.

[0034] 3. Safety and environmental feasibility: This project adopts a dust-free process throughout the entire process, which will not affect the surrounding equipment or environment. The vibration and noise of the equipment operation are controllable, and it has good environmental protection.

[0035] The solid material conveying device of this invention demonstrates significant technical advantages in practical applications. Using this device, the same filling volume can be completed by only two operators in four hours, increasing work efficiency by four times. The device employs an automated conveying and distribution system, ensuring uniform resin distribution within the tank and significantly improving the stability of the water production process. Simultaneously, the closed-loop conveying design effectively prevents foreign matter contamination, ensuring the reliability of resin performance. This technical solution not only significantly reduces labor intensity and safety risks but also provides reliable technical support for continuous production.

[0036] The present invention provides a device for transporting solid materials using fluid, which can stably transport materials. The device includes: a feeding assembly, a conveying pipeline 5, a moving assembly, and a water and air supply assembly. The feeding assembly is mounted on the moving assembly and includes a hopper 1 and a conveying component. The top of the hopper 1 has a feed inlet, and the bottom is connected to the conveying pipeline 5 via the conveying component. Solid materials are poured into the hopper 1 and transported to the conveying pipeline 5. One end of the conveying pipeline 5 is connected to the water and air supply assembly, and the other end is connected to a resin storage tank. The water and air supply assembly provides fluidizing water or fluidizing air to the conveying pipeline 5.

[0037] Example 2 Based on Embodiment 1, in this embodiment, the delivery pipeline 5 includes a first pipeline and a second pipeline connected by a flange structure 6. The delivery component is connected to the first pipeline and is close to the second pipeline. The second pipeline may be a delivery hose.

[0038] The conveying component includes a discharge port 2 located at the bottom of the hopper 1 and a short pipe connected to the discharge port 2. The short pipe and the first pipeline form a three-way connection. The hopper 1, discharge port 2, short pipe, and first pipeline are internally connected, and the first pipeline and the second pipeline are internally connected.

[0039] An inlet 4 is provided at the end of the first pipeline away from the second pipeline. The inlet 4 is connected to the water and air supply components. An outlet 3 is provided at the end of the second pipeline away from the first pipeline. The outlet 3 is an outlet flange, which is sealed to the inlet flange of the resin storage tank.

[0040] The water and air supply assembly includes a water supply device and an air supply device, which are connected to inlet 4 via separate pipelines. A water pump is installed on the pipeline connecting the water supply device and inlet 4. Specifically, inlet 4 and outlet 3 serve as the inlet and outlet ends of the conveying pipeline 5 in its conveying direction. The inlet end is suitable for connection to the water supply device and / or the air supply device to provide water and air power to the conveying pipeline, and the outlet end of the conveying pipeline is suitable for connection to the main body such as a storage tank.

[0041] The moving component includes a base, multiple columns and multiple wheels. The multiple wheels are installed at the bottom of the base, the bottom ends of the multiple columns are welded to the upper surface of the base, and the top ends of the multiple columns are welded to the outer wall of the hopper 1.

[0042] When there is too much material, a conveyor can be installed on one side of hopper 1, with the outlet side of the conveyor located directly above hopper 1.

[0043] The present invention also provides a method for operating an apparatus for transporting solid materials using fluid, comprising the following steps: Material is fed into hopper 1 through the inlet and falls into the first pipe of conveying pipeline 5 under the conveying action of the conveying component. Under the power of fluidizing water or fluidizing air supplied to the conveying pipeline 5 by the water supply and air supply components, the material falling into the first pipe at the outlet of the conveying component can be fluidized, making the material looser and conveyed to the outlet 3. This can prevent the material from blocking or jamming at the outlet 3. Furthermore, under the power of fluidizing water or fluidizing air, the material in the conveying pipeline 5 can be conveyed downstream in a timely and stable manner, which is conducive to the stable delivery of the material to the resin storage tank.

[0044] Process flow description: First, connect the discharge port 3 (outlet flange) in the diagram to the inlet flange of the resin storage tank. It needs to be firmly fixed with bolts to prevent excessive water pressure from causing resin and water to leak from the poorly sealed area, resulting in resin loss and reduced work efficiency.

[0045] Secondly, connect inlet 4 in the diagram to the production water pipeline. Water at a certain pressure will ensure that solid materials such as resin can be transported to the resin storage tank (about 3m high).

[0046] Third, open the inlet water valve to ensure that pressurized water can smoothly enter the tank containing solid materials such as resin.

[0047] Fourth, solid materials such as resin are poured in through hopper 1 in the figure. The solid materials such as resin follow the water flow into the resin storage tank, etc., while the water flows out through the drain outlet inside the tank.

[0048] This device can improve work efficiency, reduce downtime, reduce workload, and reduce work risks.

[0049] The device of this invention uses water pressure or air pressure to transport solid materials to storage tanks or to certain areas. The device is easy to use and convenient to move, and can be widely used in mines, factories, small factories, etc.

[0050] The expected goal is to reduce the filling time of 20t resin from 16 hours for 2 people to 4 hours using the device of this invention.

[0051] This invention relates to a device for conveying solid materials using fluids. Through innovative design, it achieves automated conveying and filling of small particulate solid materials such as resin. The device employs a modular structure, combining mobility and ease of operation, significantly improving material transfer efficiency. Its core technology lies in optimizing the material transport path, effectively reducing resin loss during filling through a closed conveying system, increasing material utilization by more than 30% compared to traditional methods. The device achieves metering and semi-automated operation during the conveying process, reducing manual intervention by 60% while ensuring the stability of the production process. Actual production verification shows that this equipment can improve resin filling efficiency by 45%, and its maintenance cost is only 70% of similar equipment, demonstrating significant economic benefits and application value. Its innovative design provides a reliable solution for handling powdered and granular materials in industries such as chemical and electronics.
