[0002] Composite carbon sources are widely used in wastewater treatment, microbial fermentation and other fields. Their quality directly affects the subsequent treatment effect. During the production process of composite carbon sources, various impurities, such as solid particles and microbial cells, will inevitably be mixed in. These impurities will not only reduce the purity of the composite carbon source, but may also affect the utilization efficiency of microorganisms of carbon source, and even cause problems such as pipeline blockage and equipment wear in subsequent use.

[0003] Existing impurity removal equipment for composite carbon sources achieves efficient separation of impurities within the composite carbon source through the centrifugal rotation of the centrifugal filter cartridge. However, the centrifugal filter cartridge is mounted on the inner wall of the impurity removal cylinder. After long-term use, a large number of impurity particles will adhere to the centrifugal filter cartridge, requiring cleaning by staff. However, because this installation method results in the centrifugal filter cartridge being tightly connected to the inner wall of the impurity removal cylinder, the operating space is very narrow during maintenance and cleaning, making it difficult for maintenance personnel to carry out related work. This increases the difficulty of maintenance and prolongs the time cost required for maintenance. Therefore, it is necessary to design an impurity removal device for composite carbon sources to solve the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-8 This utility model provides a technical solution: a composite carbon source impurity removal device, including a filter cylinder 1 and a top cover 2. The filter cylinder 1 is cylindrical in shape, which ensures smooth flow of the composite carbon source inside. The diameter of the top cover 2 is adapted to the diameter of the upper opening of the filter cylinder 1 and is tightly fixed to the upper opening of the filter cylinder 1 by bolts. A sealing ring is provided at the connection between the filter cylinder 1 and the top cover 2. The sealing ring is made of annular rubber material, and its inner diameter is closely fitted with the outer diameter of the opening edge of the filter cylinder 1. The outer diameter is slightly larger than the inner diameter of the connection part of the top cover 2. After tightening the bolts, it can effectively seal. The top cover 2 is provided with a feed port, which is the raw material entry channel. The feed port ensures that the composite carbon source can smoothly enter the interior of the filter cylinder 1.

[0020] A positioning seat 3 is rotatably connected to the bottom of the filter cylinder 1. Multiple connecting rods 5 are welded and fixed to the positioning seat 3. One end of the connecting rod 5 is welded and fixed to the annular cover 7. An annular frame 8 is welded and fixed to the outside of the annular cover 7. The annular frame 8 is provided with multiple through holes 16, which provide flow channels for the filtered composite carbon source, allowing it to flow smoothly from the top to the bottom of the filter cylinder 1 under the action of gravity. A limiting ring 9 is welded and fixed to the bottom of the filter cylinder 1. The annular frame 8 rotates within the limiting ring 9. The presence of the limiting ring 9 restricts the rotation range of the annular frame 8, ensuring that the annular frame 8 can only rotate within a specified trajectory and guaranteeing the stability of the rotation of the annular frame 8.

[0021] An assembly ring 11 is rotatably mounted on the upper end of the inner side of the top cover 2. The assembly ring 11 is located inside the filter cylinder 1. The upper end of the filter frame 12 is bolted to the assembly ring 11. This installation method facilitates the disassembly and replacement of the filter frame 12. The lower end of the filter frame 12 is engaged with the upper part of the annular cover 7. Specifically, the lower end of the filter frame 12 is provided with multiple positioning grooves 13. Multiple positioning plates 10 are fixed on the annular cover 7. The positioning plates 10 are inserted into the positioning grooves 13, so that the filter frame 12 and the annular cover 7 are firmly connected and are not prone to displacement during rotation. When the equipment is running, due to the tight cooperation between the positioning plates 10 and the positioning grooves 13, the filter frame 12 can rotate synchronously and stably with the annular cover 7, ensuring the stability of the rotation of the filter frame 12.

[0022] A main filter screen 17 is fixed to the filter frame 12 by bolts. A bracket 14 is welded and fixed to the lower end of the filter frame 12. An auxiliary filter screen 18 is fixed to the bracket 14 by bolts. The main filter screen 17 and the auxiliary filter screen 18 filter the composite carbon source at the same time. The diameter of the filter holes is smaller than the diameter of the impurities in the composite carbon source, ensuring that the purity of the composite carbon source after passing through the filter screen meets the standard. When the composite carbon source moves towards the main filter screen 17 and the auxiliary filter screen 18 under the action of centrifugal force generated by the rotation of the filter frame 12, the impurities cannot pass through due to the limitation of the filter screen pore size, while the composite carbon source can pass through the filter screen smoothly, ensuring the quality of the composite carbon source. The annular frame 8 is provided with multiple through holes 16, through which the filtered composite carbon source can flow to the bottom of the filter cylinder 1.

[0023] A stirring motor 19 is installed on the upper cover 2. The stirring motor 19 is fixed to a pre-set mounting base on the upper cover 2 by bolts. A rotating rod 20 is installed at the output end of the stirring motor 19 via a coupling. The rotating rod 20 passes through the upper cover 2 and extends into the filter cylinder 1, where it engages with the positioning seat 3. Specifically, the lower end of the rotating rod 20 has a locking groove 22. A locking rod 4 is welded and fixed to the positioning seat 3. The locking rod 4 is inserted into the locking groove 22, so that the rotating rod 20 can synchronously drive the positioning seat 3 to rotate during rotation. A sealing ring structure is provided at the connection between the rotating rod 20 and the upper cover 2 to prevent leakage of the composite carbon source. A stirring blade 23 is welded and fixed to the rotating rod 20. The stirring blade 23 is located inside the filter cylinder 1 and rotates under the drive of the rotating rod 20. When the stirring blade 23 rotates, it accelerates the flow rate of the composite carbon source. The principle is that the rotation of the stirring blade 23 will generate a driving force on the composite carbon source, causing the composite carbon source to form a circulation in the filter cylinder 1. This circulation can increase the contact frequency between the composite carbon source and the main filter screen 17 and the auxiliary filter screen 18, thereby improving the filtration efficiency. On the other hand, the stirring blade 23 is fixed with a transverse filter screen 24, which can filter the composite carbon source during the stirring process and intercept some impurities. The presence of the transverse filter screen 24 increases the number of filtration levels. During the stirring process of the composite carbon source, larger particles of impurities are first intercepted by the transverse filter screen 24, reducing the filtration burden on the main filter screen 17 and the auxiliary filter screen 18, and also improving the purity of the composite carbon source after final filtration.

[0024] Multiple locking pins 21 are fixed to the lower end of the rotating rod 20, and multiple locking slots 15 are provided on the bracket 14. The locking pins 21 are inserted into the locking slots 15, and the locking pins 21 and the locking slots 15 form a key connection structure. When the stirring motor 19 starts and drives the rotating rod 20 to rotate, the locking pins 21 at the lower end of the rotating rod 20 will rotate together with the rotating rod 20. Since the locking pins 21 are inserted into the locking slots 15 of the bracket 14, the torque of the rotating rod 20 is transmitted to the bracket 14 through the friction between the locking pins 21 and the locking slots 15, thereby driving the filter frame 12 connected to the bracket 14 to rotate synchronously, ensuring that the filter frame 12 rotates stably in the filter cylinder 1, and achieving efficient filtration of composite carbon sources. At the same time, this connection method is also easy to disassemble during equipment maintenance. Simply lift the rotating rod 20 upward to disengage the locking pins 21 from the locking slots 15, and the rotating rod 20 can be easily separated from the bracket 14, reducing the difficulty of maintenance.

[0025] A scraper 6 is fixed to the lower end of the connecting rod 5. The scraper 6 rotates synchronously with the rotating rod 20. During the rotation, it continuously scrapes the bottom of the filter cylinder 1, effectively cleaning and clearing the composite carbon source attached to the bottom of the filter cylinder 1. This ensures that the filtered composite carbon source can flow smoothly to the discharge port at the bottom of the filter cylinder 1. The scraper 6, through its close contact with the bottom of the filter cylinder 1, scrapes up the composite carbon source deposited at the bottom under the action of the rotating rod 20, allowing it to re-enter the flow state. This ensures that the filtered composite carbon source can continuously and stably flow through the through hole 16 to the discharge port, maintaining the normal operation of the equipment.

[0026] Working principle: When in use, the composite carbon source to be filtered is slowly injected into the filter cylinder 1 through the feed port on the top cover 2. At this time, the stirring motor 19 is started by the external power supply and the corresponding controller. The stirring motor 19 drives the rotating rod 20 to rotate. The rotating rod 20 drives the positioning seat 3 to rotate synchronously through the cooperation of the locking rod 4 and the locking groove 22. The positioning seat 3 drives the annular cover 7 to rotate through the connecting rod 5. Since the positioning plate 10 on the annular cover 7 is inserted into the positioning groove 13 at the lower end of the filter frame 12, the rotation of the annular cover 7 further drives the filter frame 12 to rotate around the axis. At the same time, the locking pin 21 at the lower end of the rotating rod 20 is tightly engaged with the locking groove 15 on the bracket 14 to ensure that the power of the rotating rod 20 is transmitted to the filter frame 12 through the bracket 14 and makes the filter frame 12 rotate in the filter cylinder 1. As the filter frame 12 rotates, the composite carbon source moves towards the main filter screen 17 on the filter frame 12 and the auxiliary filter screen 18 on the support 14 under the action of centrifugal force. The main filter screen 17 and the auxiliary filter screen 18 simultaneously filter the composite carbon source. The diameter of the filter holes of the main filter screen 17 and the auxiliary filter screen 18 is smaller than the diameter of the impurities in the composite carbon source, so that the impurities cannot pass through, thereby ensuring the purity of the composite carbon source after the filter screen. During this process, the stirring blades 23 on the rotating rod 20 also rotate synchronously. When the stirring blades 23 rotate, on the one hand, they can accelerate the flow speed of the composite carbon source, allowing the composite carbon source to contact the main filter screen 17 and the auxiliary filter screen 18 for filtration more quickly. On the other hand, the transverse filter screen 24 fixed on the stirring blades 23 can also filter the composite carbon source during the stirring process, intercept some impurities, and reduce the filtration burden of the main filter screen 17 and the auxiliary filter screen 18. After being filtered by the main filter screen 17 and the auxiliary filter screen 18, the composite carbon source flows smoothly to the bottom of the filter cylinder 1 through the through hole 16 on the ring frame 8. The scraper 6 fixed at the lower end of the connecting rod 5 rotates synchronously with the rotating rod 20, continuously scraping the inner bottom of the filter cylinder 1. This effectively cleans and clears the composite carbon source attached to the bottom of the filter cylinder 1, ensuring that the filtered composite carbon source can flow continuously and smoothly to the discharge port at the bottom of the filter cylinder 1. When the equipment has been running for a period of time, if it is necessary to clean or replace the main filter screen 17, auxiliary filter screen 18, or transverse filter screen 24, simply turn off the stirring motor 19 and stop the equipment. At this time, remove the bolts used to fix the upper cover 2 to the filter cylinder 1, and then use external hoisting tools to move the upper cover 2 upward horizontally. At this time, the filter frame 12 will move upward along the positioning plate 10, and the rotating rod 20 will move upward along the locking rod 4. When the filter frame 12 is completely separated from the inside of the filter cylinder 1, remove the bolts between the filter frame 12 and the assembly ring 11 to move the filter frame 12 downward horizontally. During the process of the bracket 14 moving downward synchronously with the filter frame 12, the slot 15 also separates from the locking pin 21 on the rotating rod 20, separating the filter frame 12 from the assembly ring 11 and the bracket 14 from the rotating rod 20. At this time, the filter frame 12 has been completely disassembled, and the main filter screen 17, auxiliary filter screen 18, and transverse filter screen 24 can be cleaned or replaced, thereby reducing the maintenance difficulty and shortening the maintenance time cost.
