Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, and in particular to a stirring device for homogenization treatment of industrial flue gas solid waste. Background Technology

[0002] In heavy industries such as power generation, metallurgy, and chemicals, when flue gas generated during combustion is discharged through flues, the particulate matter in the flue gas (such as fly ash, unburned carbon particles, and metal oxides) experiences a sudden drop in temperature, making it prone to adhesion and deposition on the inner wall of the pipe. Experimental data shows that industrial flues that have been operating continuously for more than 6 months can accumulate ash on their inner walls to a thickness of 50-150 mm, resulting in a 30%-50% reduction in effective flow area. This directly leads to increased system resistance, increased energy consumption (equipment load increases by 15%-30%), and the risk of exceeding emission standards.

[0003] Traditional manual ash removal methods require shutting down and dismantling the pipes, which is inefficient (the ash removal cycle for a single boiler can be as long as 7-15 days) and the working environment is harsh, posing safety hazards. In addition to the above-mentioned ash removal methods, workers may also use external force to vibrate the pipe wall to remove the accumulated ash, but this can easily cause cracks in the pipe welds (reducing the vibration fatigue life by more than 50%), and the ash removal rate for hard clumps is less than 40%, resulting in poor smoke and dust cleaning effect. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a stirring device for homogenization treatment of industrial dust and solid waste. This design effectively solves the problems of low work efficiency, high risk and poor cleaning effect of manual dust treatment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The present invention includes a movable arm, one end of which is rotatably connected to an elastic branch pipe, and the other end of which is fixedly connected to a rotating bracket. The rotating bracket is provided with a plurality of spiral nozzle assemblies, which communicate with the inner cavity of the elastic branch pipe. The plurality of spiral nozzle assemblies cooperate to drive the rotating bracket to rotate in one direction. A support rod is fixedly connected to the rotating bracket, and a plurality of scrapers are provided around the support rod. A self-tensioning component is installed between the scrapers and the support rod.

[0006] A connecting block is fixedly connected to the movable arm, a wheel frame is fixedly connected to the connecting block, and a roller is rotatably connected to the wheel frame, which is placed at an angle.

[0007] Preferably, the movable arm and the rotating support are provided with through holes, one end of the through hole is connected to the inner cavity of the elastic branch pipe, and the other end of the through hole is connected to the spiral nozzle assembly.

[0008] Preferably, the rotating bracket is provided with a plurality of fan-shaped mounting seats distributed at equal angles, and the fan-shaped mounting seats are provided with inclined grooves, and the spiral nozzle assembly is located in the inclined grooves.

[0009] Preferably, the self-tensioning assembly includes a first link and a second link, one end of the first link and the second link are hinged to the support rod, the first link and the second link are distributed in parallel, the other end of the first link and the second link are hinged to the scraper, a third link is hinged to the middle of the first link, a sliding sleeve is hinged to the third link, the sliding sleeve is slidably connected to the support rod, and a spring is sleeved on the support rod to apply upward force to the sliding sleeve.

[0012] Compared with the prior art, the outstanding advantages of this utility model are:

[0013] In this invention, the spiral nozzle assembly generates a spiral shearing force, which drives the rotating bracket, support rod, and moving arm to rotate through the rotating airflow. The rotation of the support rod drives the scraper to clean the inner wall of the pipe. During the cleaning process, the airflow can spray debris outward, improving cleaning efficiency. At the same time, there are inclined rollers on the moving arm. As the moving arm rotates, the rollers come into contact with the inner wall of the pipe, reducing the friction between the moving arm and the pipe, allowing the device to better extend into the inside of the pipe.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. 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.

[0021] Please see the appendix Figure 1-5 This embodiment of the stirring device for homogenizing industrial dust and solid waste includes: a movable arm 1, one end of which is rotatably connected to an elastic branch pipe 2, and the other end of which is fixedly connected to a rotating support 3. The rotating support 3 is provided with multiple spiral nozzle groups 4, which communicate with the inner cavity of the elastic branch pipe 2. The multiple spiral nozzle groups 4 cooperate to drive the rotating support 3 to rotate unidirectionally. A support rod 5 is fixedly connected to the rotating support 3, and multiple scraper blades 6 are provided around the support rod 5. A self-tensioning assembly is installed between the scraper blades 6 and the support rod 5. A connecting block 7 is fixedly connected to the movable arm 1, and a wheel frame 8 is fixedly connected to the connecting block 7. Rollers 9 are rotatably connected to the wheel frame 8, which is placed at an angle.

[0022] This device extends into the pipe. The movable arm 1 moves within the pipe, while the flexible branch 2 is located outside the pipe. The flexible branch 2 provides traction for the movement of the movable arm 1. The flexible branch 2 has an internal cavity, and an air pump is connected to its outer end. The air pump inflates the flexible branch 2, and the gas enters the cavity and exits from the spiral nozzle assembly 4. The spiral nozzle assembly 4 is evenly distributed on the rotating support 3, thus providing a uniform tangential force to the rotating support 3, thereby driving its rotation. The moving arm 1 and the support rod 5 are rotated by the motor. The scraper 6 on the periphery of the support rod 5 contacts the inner wall of the pipe. The rotation removes the dust and smoke from the inner wall of the pipe. Under the action of the self-tensioning component, the scraper 6 gradually expands outward to avoid damage to the inner wall of the pipe. The moving arm 1 has a columnar structure. There are multiple sets of connecting blocks 7 and wheel frames 8 around the moving arm 1. The wheel frames 8 and the connecting blocks 7 are placed at an angle. The end of the wheel frame 8 has a roller 9. The roller 9 contacts the inner wall of the pipe. When moving, the roller 9 reduces the friction between the inner wall of the pipe and the moving arm 1, which facilitates the movement of the device in the pipe.

[0023] The movable arm 1 and the rotating support 3 have a through hole in the middle, which connects the inner cavity of the elastic branch pipe 2 and the spiral nozzle assembly 4. This not only achieves the connection between the spiral nozzle assembly 4 and the elastic branch pipe 2, but also avoids external components from affecting the rotation of the rotating support 3.

[0024] The rotating bracket 3 has multiple sector-shaped mounting seats 10, and the arc-shaped edges of the multiple sector-shaped mounting seats 10 are tangent to the same circle. This ensures that the torsional force of the sector-shaped mounting seats 10 on the rotating bracket 3 can better drive the rotating bracket 3 to rotate. A slanted groove 11 is provided on the arc-shaped edge of the sector-shaped mounting seat 10, and the spiral nozzle assembly 4 is installed in the groove 11. This causes the outlet direction of the spiral nozzle assembly 4 to be tilted, so that the gas can better act on the inner wall of the pipe after it is ejected.

[0025] The self-tensioning assembly between the scraper 6 and the support rod 5 can automatically adjust according to the inner wall of the pipe. The scraper 6, the first connecting rod 12, the second connecting rod 13, and the support rod 5 form a parallelogram mechanism. The third connecting rod 14 is hinged to the middle of the first connecting rod 12. The third connecting rod 14 is used to adjust the angle between the first connecting rod 12 and the support rod 5. Figure 3As shown, when the first connecting rod 12 rotates upward, the scraper 6 moves outward under the action of the parallelogram mechanism, so that the scraper 6 contacts the inner wall of the pipe. Multiple third connecting rods 14 converge on a sliding sleeve 15. The spring 16 below the sliding sleeve 15 has an upward elastic force on the sliding sleeve 15. In the initial state, the spring 16 pushes the sliding sleeve 15 to the upper limit position. At this time, the scraper 6 is farthest from the support rod 5. When placed into the pipe, the scraper 6 is contracted by compressing the spring 16. After being placed inside the pipe, the sliding sleeve 15 is released, and the spring 16 pushes the sliding sleeve 15 to move. The sliding sleeve 15 drives the third connecting rod 14 and the first connecting rod 12 to make the scraper 6 stick tightly to the inner wall of the pipe. Then, under the action of the spiral nozzle assembly 4, the rotating bracket 3, the moving arm 1 and the support rod 5 rotate synchronously, so that the scraper 6 moves and rotates inside the pipe, removing the dust from the inner wall of the pipe.

[0026] Furthermore, to improve the cleaning effect of scraper 6 on the dust inside the pipe, scraper 6 has a triangular prism structure. The edges of scraper 6 can better peel and break up the dust on the inner wall of the pipe. In addition, oblique scraper strips 17 are installed on the side of scraper 6. The scraper strips 17 provide raised ridges to the side of scraper 6, which can better break up the lumps of dust and make the cleaning inside the pipe more thorough.

[0027] A tapered top rod 18 is installed on the top of the support rod 5. The top rod 18 has crushing teeth on its side. The top rod 18 acts as an open circuit, performing simple crushing at the front end of the device to facilitate the forward movement of the scraper 6 in the pipeline.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
