Description

Technical Field

[0001] This utility model relates to the field of tumbling machine technology, and in particular to a tumbling chamber for making composite denitrification agent granules tumbling machine. Background Technology

[0002] Composite denitrification agent particles play a key role in the flue gas denitrification process. Their particle size uniformity, density and molding quality directly affect the activity and service life of the denitrification agent. Most of the tumbling machines commonly found on the market are simple horizontal or vertical drum structures, which mainly rely on the rotation of the drum itself and the gravity sliding of the material in the drum to achieve mixing and molding.

[0003] Pure drum rotation often causes some materials to slide only at the bottom of the drum, making it difficult to achieve multi-level mixing. This results in uneven distribution of active ingredients in the particles, affecting the denitrification effect. At the same time, the lack of effective inner wall scrapers and knocking structures makes it easy for materials to adhere to the drum wall during the rolling process, forming clumps. This requires frequent shutdowns for cleaning, reducing equipment utilization. Utility Model Content

[0004] The purpose of this invention is to provide a tumbling chamber structure that can efficiently process materials under multiple mechanical actions such as rolling, shearing, and impact.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tumbling chamber for a tumbling machine for manufacturing composite denitrifying agent granules, comprising a mounting frame and a tumbling pot, wherein the tumbling pot is provided with a discharge pipe and a feed pipe;

[0006] The mounting frame is equipped with a drive assembly, which includes a rotary motor fixed to the mounting frame, a gear ring fixedly sleeved on the outer ring of the tumbling pot, and a gear fixed to the output shaft of the rotary motor, wherein the gear meshes with the gear ring.

[0007] The tumbling pot is equipped with a rotating rod, one end of which passes through the end wall of the tumbling pot and is connected to the output shaft of the rotary motor via a belt drive mechanism.

[0008] Several tumbling paddles are fixed to the outer wall of the rotating rod, and several partitions are welded to the inner wall of the tumbling pot. Several striking plates are hinged between adjacent partitions.

[0009] As a further description of the above technical solution: the rotation direction of the rotating rod is opposite to the rotation direction of the tumbling pot.

[0010] As a further description of the above technical solution: the belt drive mechanism includes a driving wheel and a driven wheel with different diameters, so that there is a speed difference between the tumbling pot and the rotating rod.

[0011] As a further description of the above technical solution: the partitions are evenly distributed along the circumference of the inner wall of the tumbling pot, and the number is 4-8.

[0012] As a further description of the above technical solution: the tumbling paddle is a paddle-type or spiral structure, and is arranged at equal intervals along the axis of the rotating rod.

[0013] As a further description of the above technical solution: the striking plate is hinged to the side wall of the partition by a pin, and its surface can swing freely under the impact of materials.

[0014] As a further description of the above technical solution: the discharge pipe is located on the bottom side wall of the tumbling pot, and the feed pipe is located on the top side wall of the tumbling pot.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] 1. The baffles on the inner wall continuously lift and scatter the material, and the hinged striking plate swings and flips under the impact of the material, forming a knocking and breaking effect and self-cleaning effect, effectively preventing the material from sticking to the wall and reducing the number of times the machine needs to be stopped for cleaning.

[0017] 2. The rotary motor drives the tumbling pot to rotate through gears and a gear ring. At the same time, it drives the central rotating rod in the opposite direction through a belt mechanism. The speed difference between the two gives the material a shearing force in opposite directions, which effectively enhances the mixing and kneading effect and improves the dispersion uniformity of active ingredients.

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-3This utility model provides a technical solution: a tumbling chamber for a tumbling machine for manufacturing composite denitrification agent granules, including a mounting frame 10, which serves as the supporting foundation for the entire device and ensures stable operation of the equipment. A tumbling pot 11 is installed at an angle on the mounting frame 10. The body of the tumbling pot 11 is a hollow cylindrical barrel structure. This angled arrangement utilizes gravity to allow the material to move naturally and slowly from the top to the bottom during the tumbling process, facilitating feeding and discharging. Specifically, the axis of the tumbling pot 11 forms an acute angle with the horizontal plane. At the lower end of the tumbling pot 11, a discharge pipe 111 is provided for discharging the fully tumbled material; at the higher end of the tumbling pot 11, a feed pipe 112 is provided for feeding the powdered raw material of the composite denitrification agent and the liquid binder into the pot.

[0025] The mounting frame 10 is equipped with a drive assembly, which includes a rotary motor 13 fixed to the mounting frame 10. Specifically, in order to drive the tumbling pot 11 to rotate, a gear ring 12 is fixedly sleeved on the outer ring of the tumbling pot 11 near the higher end of the terrain. Correspondingly, a rotary motor 13 is mounted on the mounting frame 10 as a power source. A gear 14 is fixedly sleeved on the output shaft of the rotary motor 13. The gear 14 meshes with the gear ring 12 on the tumbling pot 11. When the rotary motor 13 starts, its power is transmitted to the gear ring 12 through the gear 14, thereby driving the entire tumbling pot 11 to rotate stably around its own central axis.

[0026] Inside the tumbling pot 11, a rotating rod 15 is rotatably mounted on the same axis. One end of the rotating rod 15 passes through the center of the end wall of the higher end of the tumbling pot 11. The rotating rod 15 is connected to the output shaft of the rotary motor 13 via a belt drive mechanism.

[0027] The power output of the rotary motor 13 is split into two: one drive is to rotate the tumbling pot 11 through the meshing of the gear 14 and the gear ring 12; the other drive is to rotate the rotating rod 15 through the belt drive. The rotation direction of the rotating rod 15 is opposite to that of the tumbling pot 11. This reverse rotation design allows the material to be subjected to shearing forces in opposite directions in the cavity, which greatly enhances the mixing and tumbling effect. At the same time, by adjusting the diameter ratio of the pulleys, the speed difference between the tumbling pot 11 and the rotating rod 15 can be achieved, further optimizing the process parameters.

[0028] Multiple tumbling paddles 16 are uniformly fixedly welded along the axial direction on the outer periphery of the rotating rod 15. The shape of the tumbling paddles 16 can be paddle-shaped or spiral-shaped. Their function is to stir, push, turn and knead the material in the tumbling pot 11 under the drive of the rotating rod 15. They are the main source of power to achieve uniform mixing and densification of the material.

[0029] To further improve tumbling efficiency and prevent materials from sticking to the walls and clumping, several baffles 17 extending axially are fixedly welded onto the inner wall of the tumbling pot 11. When the tumbling pot 11 rotates, these fixed baffles 17 continuously lift and raise the materials at the bottom to a higher position. Then, the materials fall due to gravity, forming a continuous tumbling and scattering effect, thus avoiding the problem of uneven mixing caused by materials only sliding at the bottom of the pot.

[0030] Between two adjacent partitions 17, several striking plates 18 are rotatably installed. The striking plates 18 are hinged between the partitions 17 by means of pins or the like. When the tumbling pot 11 rotates and the partitions 17 lift the material, these loose or somewhat sticky material clumps will impact the striking plates 18 below, or collide with the striking plates 18 that are lifted during the fall. Since the striking plates 18 are rotatable, they will swing and flip under the impact of the material, forming a knocking and patting effect. This mechanical knocking action can effectively break up the larger clumps that are forming, and at the same time, it can effectively prevent the material from sticking to the pot body and the partitions 17, ensuring the looseness of the material and the uniformity of the mixing.

[0031] Work steps:

[0032] The compound denitrification agent dry powder and liquid binder, which are mixed in proportion, are fed into the tumbling pot 11 through the feed pipe 112 at the top.

[0033] When the rotary motor 13 is started, the tumbling pot 11 and the internal rotating rod 15 start to rotate simultaneously. The rotating tumbling paddle 16 performs forced shearing, kneading and stirring of the material from the inside. The rotating tumbling pot 11 and the partition 17 continuously lift the material from the bottom, causing it to tumble and fall.

[0034] During the tumbling and falling process, the material collides and slaps against the rotating striking plate 18, further breaking up clumps and preventing them from sticking together.

[0035] Because the tumbling pan 11 is tilted as a whole, the material that has been fully mixed and kneaded into a uniform masterbatch will gradually move to the bottom under the force of gravity and the push of subsequent materials, and will eventually be continuously discharged from the discharge pipe 111 to enter the next granulation process.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
