Description

Technical Field

[0001] This utility model relates to the field of condensate polishing technology, specifically to a condensate polishing resin conveying anti-clogging device. Background Technology

[0002] In steam circulation systems such as thermal power plants and nuclear power plants, the quality of condensate water is directly related to the safe and stable operation of thermal equipment. Condensate fine treatment is a key step in ensuring condensate water quality and preventing corrosion and scaling of thermal equipment, which is of great significance for extending equipment service life and improving system operating efficiency. Currently, condensate polishing primarily relies on ion exchange resins for water purification, including strongly acidic cation exchange resins (such as styrene-based sulfonic acid resins) and strongly basic anion exchange resins (such as quaternary ammonium resins). Strongly acidic cation exchange resins are mainly used to remove impurities from condensate. , , Anion exchange resins containing both cationic and strongly basic elements are mainly used for the removal of... , Anionic resins, through the synergistic effect of the two types of resins, can effectively reduce the ion content in condensate, thus meeting the system's water quality requirements. In practical applications, the exchange capacity of ion exchange resin particles gradually decreases after a period of use, requiring replacement to ensure the purification effect. Currently, the resin replacement process mainly involves manual operation. Specifically, the operator aligns the resin bag with the feeding port, pours the resin particles into the resin delivery pipe, and then transports the resin to the designated location through the delivery pipe. However, the aforementioned manual resin addition process has the following drawbacks: During transport, resin particles, due to their inherent characteristics and the influence of the transport environment, easily adhere to the inner walls of the conveying pipes and the feeding hopper. This leads to a reduction in the actual amount of resin delivered to the target location, decreasing transport efficiency and affecting the resin replacement schedule. Furthermore, the adhered residual resin requires manual cleaning, increasing the workload of operators; the cleaning process is cumbersome, time-consuming, and labor-intensive. In addition, if the residual resin is not cleaned in time, it is prone to clumping when environmental humidity and temperature change, further exacerbating the risk of blockage in the conveying pipes and feeding hopper, affecting subsequent resin addition and transport.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] Example To address the technical problems in the background art, the following anti-clogging device for conveying condensate polishing resin is provided: Combination Figures 1-6As shown, this utility model provides a condensate polishing resin conveying anti-clogging device, comprising: a mounting platform 100, two sets of feeding hoppers 200 fixedly mounted on the top of the mounting platform 100, a guiding component 800 rotatably mounted inside the feeding hopper 200, a cleaning unit 300 extending into the top of the feeding hopper 200 fixedly mounted, a conveying pipe 500 communicating with the feeding hopper 200 fixedly mounted on the top inside the mounting platform 100, and a mounting shell 600 fixedly mounted on the top inside the mounting platform 100. The assembly includes a drive unit 700 for driving the material guiding component 800; the cleaning unit 300 includes a mounting frame 301, a servo motor 302, a mounting plate 303, and an internal plate 305. The mounting frame 301 is fixedly mounted on the top of the feeding bin 200, and the servo motor 302 is fixedly mounted on the top of the mounting frame 301. The output end of the servo motor 302 passes through the mounting frame 301 and is connected to the mounting plate 303. The internal plate 305 extending into the feeding bin 200 is fixedly mounted at the end of the mounting plate 303.

[0015] Mounting platform 100: As a basic support structure, two sets of feeding hoppers 200 are fixed on the top; Feeding hopper 200: Internal rotating guide component 800, top extending to internally installed cleaning unit 300; Conveying pipe 500: Connects to the feeding hopper and is used for resin conveying; Mounting housing 600: Built-in drive unit 700 for driving the material guiding component 800; Cleaning unit 300: Servo motor 302 drives the mounting plate 303 to rotate, which in turn drives the built-in plate 305 and the rubber scraper 304 to scrape the inner wall of the feeding hopper to prevent resin residue. Drive unit 700: Servo motor 701 drives shaft 704 through main gear 702 and secondary gear 703, and is connected to guide component 800 via magnetic coupler 705; Material guiding component 800: The shaft 801 cooperates with the spiral blade 802 to accelerate resin delivery when rotating.

[0016] In this embodiment, a rubber scraper 304 is fixedly installed on the inner side of the built-in plate 305, and the built-in plate 305 scrapes the inner wall of the feeding bin 200 through the rubber scraper 304.

[0017] The rubber scraper 304 is installed inside the built-in plate 305. Through the rotation of the servo motor 302, it periodically scrapes the inner wall of the feeding hopper to ensure that there is no resin residue. It is cleaned after the operation or scraped in real time when conveying high viscosity resin.

[0018] In this embodiment, the drive unit 700 includes a second servo motor 701, a main gear 702, a secondary gear 703, a rotating shaft 704, and a magnetic coupler 705. The second servo motor 701 is fixedly installed at the bottom of the mounting housing 600. The output end of the second servo motor 701 extends into the mounting housing 600 and is connected to the main gear 702. Two sets of rotating shafts 704 are rotatably installed inside the mounting housing 600. One end of the rotating shaft 704 is fixedly connected to the secondary gear 703 that meshes with the main gear 702. A connecting connector 400 is fixedly installed on one side of the conveying pipe 500. The shaft 801 passes through the connector 400 and extends into the conveying pipe 500. A sealing sleeve 401 is fixedly connected to the inner wall of the connector 400.

[0019] The other end of the rotating shaft 704 is fitted with a magnetic coupler 705, and the rotating shaft 704 is connected to the material guiding component 800 via the magnetic coupler 705.

[0020] The magnetic coupler 705 enables selective drive of the device: the connection between the rotating shaft 704 and the shaft 801 is controlled by the magnetic coupler 705. When operating a single feeding hopper, only the corresponding magnetic coupler is activated; When both groups are operating simultaneously, all magnetic couplers are activated.

[0021] In this embodiment, the material guiding component 800 includes a shaft 801 and a spiral blade 802. The shaft 801 is installed inside the conveying pipe 500. The outer end of the shaft 801 extends into the mounting shell 600 and is connected to the magnetic coupler 705. The spiral blade 802 is fixedly installed on the shaft 801 inside the conveying pipe 500.

[0022] Select the resin hopper to be conveyed, activate the corresponding material guiding component 800 through the drive unit 700, and the spiral blade 802 rotates to propel the resin. The function of the spiral blade 802 is to propel the resin in a directional manner when rotating, thereby improving the conveying efficiency, and it is especially suitable for high-density resin powder.

[0023] In this embodiment, a mounting base 601 is fixedly mounted on the top of the mounting shell 600, and the mounting shell 600 is fixed to the top of the mounting platform 100 through the mounting base 601.

[0024] The mounting base 601 enables the installation connection between the mounting shell 600 and the mounting platform 100. The two are fixed together by components, which facilitates disassembly, inspection and maintenance in the future.

[0025] Working principle and usage process of this utility model: In use, the electrical components on the device are connected to an external controller via wires, and the controller is used for power control. The motor and coupler in the electrical components are existing and widely used in the field, so they will not be elaborated on here. During the process, the resin is injected through the feeding hopper 200 and then vertically enters the conveying pipe 500 for conveying. The two sets can be used for feeding and conveying strong acidic cationic resin powder and strong basic anionic resin respectively. The second step is to accelerate the conveying speed of the resin conveying pipe 500 during the conveying process. The servo motor 701 can be started to drive the auxiliary gear 703 to rotate through the main gear 702. The magnetic coupler 705 on the corresponding rotating shaft 704 can be started according to actual needs to couple with the shaft 801. If both sets of feeding bins 200 need to convey, the magnetic coupler 705 can be started at the same time to complete the connection between the rotating shaft 704 and the shaft 801. At that time, the spiral blade 802 on the shaft 801 will rotate to accelerate the conveying of the resin. The third step is to start the servo motor 302 after the work is completed. The servo motor 302 drives the mounting plate 303 to rotate, causing the built-in plate 305 to use the rubber scraper 304 to scrape the inner wall of the feeding bin 200, thereby cleaning the resin on the inner wall of the feeding bin 200.
