Description

Technical Field

[0001] This utility model relates to the field of cyclone separation equipment, specifically to a cyclone cone structure that prevents clogging. Background Technology

[0002] A cyclone separator is a device that uses centrifugal force to achieve gas-solid separation. As a highly efficient, simple, and easy-to-maintain gas-solid separation device, it is widely used in industries such as power, metallurgy, chemical, and building materials for primary or intermediate purification of dust-laden gases. One of the core components of a cyclone separator is the lower conical section, or simply cone. By forming a high-speed rotating airflow, centrifugal force is used to throw particles against the wall and allow them to slide down the cone wall to the discharge port.

[0003] However, when handling dust with high humidity, high viscosity, or easy agglomeration characteristics, the traditional straight cone structure is prone to dust accumulation problems. This is especially true in the processing of materials such as cement raw material powder, where the trace moisture content causes the dust to have a certain degree of adhesion, thus forming a dust layer that is difficult to clean. This dust layer not only reduces the effective flow area of ​​the cyclone separator and lowers the separation efficiency, but also increases the system operating resistance and energy consumption. After the dust accumulates on the cone wall, it is easy to form hard clumps, requiring the entire system to be shut down for manual cleaning, increasing maintenance and time costs, and reducing the continuity and efficiency of production.

[0004] Therefore, it is necessary to invent a cyclone cone structure that prevents clogging to solve the above problems. Utility Model Content

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figure 1 and Figure 2 The diagram shows an anti-clogging cyclone cone structure, including a cone shell 1, which is an inverted frustum-shaped structure that is wider at the top and narrower at the bottom, used to guide dust-laden gas to rotate and achieve gas-solid separation. The cone shell 1 is arranged from top to bottom as a first guide section 11, a second guide section 12 and a third guide section 13, with the inner diameter of each guide section decreasing step by step, and the guide sections are connected by a smooth transition curved surface to optimize the airflow field distribution and reduce the generation of local eddies. A vibration unclogging component 3 is provided inside the cone shell 1, and a drive component 2 is provided outside the cone shell 1.

[0018] like Figure 2 - Figure 4As shown, the vibration unblocking assembly 3 includes a guide rod 31, a sleeve 32, and an elastic ring 33. The sleeve 32 is coaxially sleeved on the outer wall of the guide rod 31 and can reciprocate in the axial direction of the guide rod 31. The right end of the guide rod 31 is fixedly connected to the inner wall of the conical shell 1. The sleeve 32 passes through and is slidably connected to the left side wall of the conical shell 1. The elastic ring 33 is slidably connected to the outer wall of the guide rod 31. The left side of the elastic ring 33 abuts against the right side of the sleeve 32. A limiting block 34 is fixedly connected to the outer wall of the guide rod 31 to limit the axial displacement range of the elastic ring 33. The right side of the elastic ring 33 abuts against the left side of the limiting block 34. The elastic ring 33 is located between the sleeve 32 and the limiting block 34. The elastic ring 33 is made of a metal material with elasticity and recovery ability, namely spring steel. When not subjected to external force, it has a closed ring structure with a circular cross-section. When subjected to axial pressure and squeezed by the compression column 3... 5. When the force is transmitted, elastic deformation occurs, and the cross-section becomes elliptical. After release, it automatically returns to its original shape. At least four extrusion columns 35 are fixedly connected to the outer wall of the elastic ring 33, which are evenly distributed in the circumference. When the sleeve 32 is driven to move to the right, it pushes the elastic ring 33 to compress and deform, causing the extrusion columns 35 to expand radially outward and impact the dust accumulation area on the inner wall of the cone shell 1, achieving local impact clearing. A vertically arranged cutting rod 36 is fixedly connected to the outer wall of the elastic ring 33. The cutting rod 36 has a cuboid structure, and both sides of the cutting rod 36 are provided with blades 361. The included angle of the blades 361 is acute, and the surface of the blades 361 is coated with titanium nitride to enhance the sharpness and wear resistance of the blades 361, making it easier to cut the clumps of dust. A connecting plate 37 is fixedly connected to the left side of the sleeve 32. The connecting plate 37 is connected to the drive assembly 2 for transmission, which drives the sleeve 32 to perform reciprocating linear motion.

[0019] like Figure 1 and Figure 2 As shown, the drive assembly 2 includes a linear motor 21 and a U-shaped motor mounting base 22. The linear motor 21 is fixedly connected to the top of the motor mounting base 22. The linear motor 21 is model 20DAM-L, with a stroke of 50-80mm and an output thrust of 500-800N. The output end of the linear motor 21 extends to the right and is fixedly connected to the left side of the connecting plate 37. It is used to drive the sleeve 32 to perform periodic reciprocating motion along the axis of the guide rod 31. The bottom plate of the motor mounting base 22 is provided with multiple mounting holes 23. These mounting holes 23 are used to pass bolts through to fix the motor mounting base 22 as a whole to the ground or support platform to ensure stability during the drive process. The bolt specifications are M10-M14, and spring washers are provided between the bolts and the mounting holes 23 to prevent the bolts from loosening.

[0020] like Figure 1 and Figure 2As shown, the cone shell 1 is detachably connected to the bottom dust discharge port of the cyclone body by the fastener 14, which facilitates maintenance and replacement. The bottom of the cone shell 1 is provided with a discharge port 15, which is connected to the downstream ash conveying equipment for continuous discharge of separated solid particles.

[0021] The working principle of this practical system is as follows: During the cement production process, the airflow containing cement dust enters through the inlet of the cyclone separator body and then flows downward along the inner wall of the conical shell 1. Under the action of centrifugal force, it forms a high-speed rotating airflow and spirals downward into the conical shell 1. The gas passes through the first guide section 11, the second guide section 12, and the third guide section 13 in sequence. Under the action of centrifugal force, cement dust particles are thrown towards the inner wall of the cone. Then, under the combined action of gravity and airflow thrust, they slide downward along the inner wall. At this time, the larger inner diameter of the first guide section 11 can accommodate high-flow airflow and avoid dust rebound caused by excessive airflow velocity. The gradually changing inner diameter of the second guide section 12 further accelerates the airflow rotation and enhances the centrifugal separation effect. The smaller inner diameter of the third guide section 13 ensures that the dust particles can concentrate and move towards the bottom. Finally, they enter the downstream ash conveying equipment through the discharge port 15 at the lowest end of the conical shell 1, realizing the separation of cement dust and clean gas.

[0022] During long-term operation, cement dust containing trace amounts of moisture has a certain degree of stickiness and easily adheres to the inner wall of the cone shell 1, easily forming dust accumulation. If it is not cleaned in time, it will cause the cone channel to narrow and affect the separation efficiency. At this time, the vibration unblocking component 3 and the drive component 2 start together to achieve real-time unblocking. First, the linear motor 21 is started. The output end of the linear motor 21 pushes the connecting plate 37 to move linearly to the right. This power is transmitted to the sleeve 32 through the connecting plate 37, causing it to slide forward along the axial direction of the guide rod 31. As the sleeve 32 moves to the right, its right end face continuously presses the elastic ring 33 to compress it towards the limiting block 34.

[0023] Because the two ends of the elastic ring 33 are constrained, it undergoes elastic deformation under axial pressure. The closed ring, which was originally circular in cross-section, gradually becomes elliptical, causing the multiple extrusion columns 35 fixed on its outer periphery to expand outward radially in sync. When the expansion reaches its maximum value, the extrusion column 35 violently impacts the dust accumulation area on the inner wall of the cone shell 1, generating a local shock wave that shatters the solidified dust layer, destroys its adhesion, and causes the loose material to fall off and be discharged into the discharge port 15 below.

[0024] At the same time, the vertical cutting rod 36, which is fixed to the outer wall of the same elastic ring 33, also moves up and down as the whole moves. The cutting rod 36 adopts a cuboid structure, with sharp-angled cutting edges 361 on both sides. The surface is coated with a titanium nitride wear-resistant coating with a hardness of over 2800HV. During the reciprocating motion, the cutting edge 361 acts like a scraper to shear and peel off wet, sticky or initially crusted dust, effectively preventing the formation of a continuous adhesive layer.

[0025] When the output of the linear motor 21 resets to the left, the sleeve 32 moves to the left accordingly, the axial pressure on the elastic ring 33 disappears, and it returns to its initial circular state under the action of its own elastic restoring force. The extrusion column 35 also retracts synchronously, completing one impact unblocking cycle. In humid weather during cement production, the probability of dust agglomeration increases. The cutting action of the blade 36 can ensure that the discharge port 15 is always unobstructed and that there is no jamming when connecting with the downstream screw conveyor, thus achieving continuous dust discharge.

[0026] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
