Description

Technical Field

[0001] This utility model relates to the field of resin particle conveying technology, specifically to an ion exchange resin conveying device. Background Technology

[0002] Screw conveyors, also known as auger conveyors, are widely used material conveying equipment in industries such as chemical, mining, food, and construction. They are particularly suitable for conveying ion exchange resin particles (usually spherical particles). Their main function is to achieve continuous material transport, efficiently handling various types of materials, including granules, powders, and lumps, meeting the needs of large-scale production. Screw conveyors have a relatively compact structure, typically consisting of a casing, helical blades, a drive unit, an inlet and outlet, and a support frame. The casing provides protection, while the helical blades are the core component, responsible for propelling the material. The drive unit provides the necessary power; through the cooperation of an electric motor and a reducer, the helical blades rotate, and the material... Driven by gravity and blades, the material enters from the feed inlet and is conveyed along the spiral direction to the discharge outlet. Currently, screw conveyors used for ion exchange resin particles are mainly single-chamber structures. In this case, the ion exchange resin particles in the hopper have poor flowability and are prone to "bridging" under gravity, preventing the material from flowing smoothly into the screw conveyor. Furthermore, ion exchange resin particles also have a certain degree of adhesion and flowability. Especially in humid or damp environments, the particles are prone to sticking together and forming clumps. When these clumps enter the feed inlet of the screw conveyor through the hopper, they can easily cause local blockages, hindering the normal flow of the material. As a result, the material cannot be discharged smoothly, causing the production line to stagnate and affecting the overall production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an ion exchange resin conveying device. A double-tube auger conveyor is installed at the bottom of a conical storage tank. Ion exchange resin particles in the conical storage tank enter the double-tube auger conveyor through the conical wall and are continuously conveyed out. During this process, a centrally located material-pulling structure synchronously receives rotational power from a gear drive unit, a synchronous wheel transmission structure, and a worm gear reduction transmission structure to agitate the granular material in the conical storage tank, allowing it to smoothly enter the double-tube auger conveyor, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an ion exchange resin conveying device, comprising a frame, a conical storage tank installed at the center of the top of the frame, a double-tube auger conveyor installed on two discharge ports on the bottom slope wall of the conical storage tank, and an L-shaped base installed inside the frame on one side of the double-tube auger conveyor. A gear drive unit for driving the double-tube auger conveyor is installed on the inner wall of one side of the L-shaped base. A centrally located material feeding structure is provided in the central axis area inside the conical storage tank. A synchronous wheel transmission structure is installed on the output shaft of the gear drive unit. A worm gear reduction transmission structure is provided at the top of the conical storage tank for receiving the rotational power from the synchronous wheel transmission structure and driving the centrally located material feeding structure.

[0005] Preferably, a feeding port is installed at one edge of the top of the conical storage tank, and a discharge valve is installed at the center of the bottom of the conical storage tank.

[0006] Preferably, the gear drive unit includes a geared motor mounted on the inner wall of one side of the L-shaped base frame, a primary gear mounted on the output shaft of the geared motor, and secondary gears fixed to the ends of the two auger shafts of the twin-tube auger conveyor, wherein the primary gear and the two secondary gears mesh with each other.

[0007] Preferably, the worm gear reduction transmission structure includes a shaft frame fixed on one side of the outer wall of the conical storage tank, a worm body rotatably mounted on the side of the shaft frame near the outer wall of the conical storage tank, and a worm wheel body mounted on the top of the centrally located material feeding structure. The worm body and the worm wheel body mesh with each other, and the other end of the worm body is connected to the output shaft of the reduction motor through a synchronous wheel transmission structure.

[0008] Preferably, the synchronous pulley transmission structure includes a driving pulley mounted on the output shaft of the geared motor, a driven pulley fixed to one end of the shaft frame, and a synchronous belt wound between the driven pulley and the driving pulley.

[0009] Preferably, the centrally located material feeding structure includes a central shaft rotatably mounted at the center of the top of the conical storage tank, a connecting sleeve fixed at one end of the surface of the central shaft, and side rods fixed on both sides of the bottom end of the connecting sleeve. A material feeding paddle is fixed on one outer wall of the side rods, and the top end of the central shaft extends through to the outside of the conical storage tank and is fixedly connected to the bottom end of the worm gear body.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This ion exchange resin conveying device is equipped with a structure that integrates a conical storage tank, a double-tube auger conveyor, a gear drive unit, a synchronous wheel transmission structure, and a worm gear reduction transmission structure. The conical storage tank design allows the material to flow naturally into the double-tube auger conveyor under gravity. The conical structure effectively guides the material downwards, reducing its residence time in the storage tank. The centrally located material-pulling structure, through the cooperation of the gear drive unit and the worm gear reduction transmission structure, periodically agitates the granular material in the storage tank, ensuring that the material can smoothly enter the double-tube auger conveyor. Compared with a single-tube design, the double-tube auger conveyor has a greater conveying capacity and better material handling. The material adaptation design enables more efficient material conveying, especially in large-scale production, significantly improving production efficiency. The synergistic effect of the centrally located material feeding structure ensures uniform material supply, preventing material accumulation at the inlet and further enhancing overall conveying efficiency. Secondly, the centrally located material feeding structure design enables uniform distribution of materials within the storage tank. By periodically feeding materials, it effectively prevents concentrated accumulation of materials within the conical storage tank, ensuring that materials enter the twin-tube auger conveyor evenly. Finally, the synchronous operation of the centrally located material feeding structure and the twin-tube auger conveyor effectively prevents material blockage and reduces the residence time of materials in the storage tank, thereby reducing equipment maintenance and labor costs and ensuring continuous operation of the production line.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figure 1-5 An embodiment of this utility model provides an ion exchange resin conveying device, comprising a frame 1, a conical storage tank 2 installed at the center of the top of the frame 1, a double-pipe auger conveyor 4 installed on two discharge ports on the bottom slope wall of the conical storage tank 2, and an L-shaped base frame 3 installed inside the frame 1 on one side of the double-pipe auger conveyor 4. A feeding port 6 is installed at one edge of the top of the conical storage tank 2, and a discharge valve 5 is installed at the center of the bottom of the conical storage tank 2.

[0019] A gear drive unit 8 for driving the double-tube auger conveyor 4 is installed on the inner wall of one side of the L-shaped base frame 3. The double-tube design of the double-tube auger conveyor 4 greatly enhances the conveying capacity, enabling it to convey a large amount of material in a short time. It is suitable for high-volume production environments. Furthermore, due to the rotation of the auger, it can effectively reduce the wear and loss of materials during the conveying process and improve the utilization rate of materials.

[0020] A central material feeding structure 7 is provided in the central axis area inside the conical storage tank 2. A synchronous wheel transmission structure 10 is installed on the output shaft of the gear drive unit 8. A worm gear reduction transmission structure 9 is provided at the top of the conical storage tank 2 to receive the rotational power from the synchronous wheel transmission structure 10 and drive the central material feeding structure 7 to work.

[0021] The gear drive unit 8 includes a geared motor 801 mounted on the inner wall of one side of the L-shaped base frame 3, a primary gear 802 mounted on the output shaft of the geared motor 801, and secondary gears 803 fixed to the ends of the two auger shafts of the twin-tube auger conveyor 4. The primary gear 802 and the two secondary gears 803 mesh with each other. When the gear drive unit 8 is working, the power supply connected to the geared motor 801 is turned on, and the output shaft of the geared motor 801 drives the secondary gears 803 on both sides to rotate through the primary gear 802. The secondary gears 803 drive one of the auger shafts of the twin-tube auger conveyor 4 to rotate, thereby enabling the twin-tube auger conveyor 4 to work stably. During this process, the gear transmission can withstand a large load, which is suitable for conveying granular materials and ensures the stable operation of the device.

[0022] The worm gear reduction transmission structure 9 includes a shaft frame 901 fixed on one side of the outer wall of the conical storage tank 2, a worm body 902 rotatably mounted on the outer wall of the shaft frame 901 near the conical storage tank 2, and a worm wheel body 903 mounted on the top of the central material feeding structure 7. The worm body 902 and the worm wheel body 903 mesh with each other. The other end of the worm body 902 is connected to the output shaft of the reduction motor 801 through the synchronous pulley transmission structure 10. The synchronous pulley transmission structure 10 includes a driving pulley mounted on the output shaft of the reduction motor 801, a driven pulley fixed on one end of the shaft frame 901, and a synchronous belt wound between the driven pulley and the driving pulley.

[0023] The central material feeding structure 7 includes a central shaft 701 rotatably installed at the center of the top of the conical storage tank 2, a connecting sleeve 702 fixed at one end of the surface of the central shaft 701, and side rods 703 fixed on both sides of the bottom end of the connecting sleeve 702. The output shaft of the geared motor 801 drives the worm body 902 in the worm gear reduction transmission structure 9 to rotate through the synchronous wheel transmission structure 10. Then, the worm body 902 drives the central shaft 701 and the connecting sleeve 702 to rotate through the worm wheel body 903. The worm gear can achieve a large reduction ratio, which is suitable for applications that require low speed and high torque. It can effectively meet the heavy load requirements. The worm gear has a self-locking characteristic, which can keep the load from slipping when the machine stops.

[0024] A material-pushing paddle 704 is fixed on one outer wall of the side rod 703. The top end of the central shaft 701 extends through to the outside of the conical storage tank 2 and is fixedly connected to the bottom end of the worm gear body 903. After the central shaft 701 and the worm gear body 902 are driven to rotate, the side rod 703 and the material-pushing paddle 704 will rotate around the central shaft 701, and the material-pushing paddle 704 will push the separated material in the conical storage tank 2, thereby improving the flowability of the material and reducing the blockage.

[0025] In this embodiment, during use, the operator first feeds sufficient ion exchange resin particles into the conical storage tank 2 through the feeding port 6, ensuring that the ion exchange resin particles can flow smoothly into the conical storage tank 2. Next, the gear drive unit 8 is activated, and a portion of the rotational power of the gear drive unit 8 is transmitted to the twin-tube auger conveyor 4. The two augers in the twin-tube auger conveyor 4 rotate and begin to push the granular material in the conical storage tank 2 toward the discharge port. During this process, the ion exchange resin particles in the conical storage tank 2 directly enter the twin-tube auger conveyor 4 along the conical wall. While the gear drive unit 8 is working, it also transmits rotational power to the central feeding structure 7 through the synchronous wheel transmission structure 10 and the worm gear reduction transmission structure 9, thereby activating the central feeding structure 7. The feeding structure 7 works in conjunction with the twin-tube auger conveyor 4. The central feeding structure 7 moves the granular material in the conical storage tank 2, allowing it to flow evenly into the twin-tube auger conveyor. Operators need to adjust the feeding frequency of the central feeding structure 7 and the conveying speed of the twin-tube auger conveyor 4 according to the material flow to ensure that the material does not accumulate or become blocked in the conical storage tank. During the conveying process, the outlet of the twin-tube auger conveyor 4 is observed to confirm whether the ion exchange resin granules are being conveyed evenly and continuously. After the ion exchange resin granules are conveyed, the gear drive unit 8 is turned off to ensure the device stops operating. The conveying device is then cleaned, especially the outlet and the inside of the conical storage tank 2, to ensure no residual material remains for smooth operation next time.
