Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment, and in particular to a horizontal cyclone treatment device. Background Technology

[0002] Cyclone dust collectors, as key equipment in industrial dust removal, are widely used in industries such as metallurgy, chemicals, and building materials to treat high-concentration dusty gases. Their core principle is to achieve gas-solid separation through the centrifugal force generated by the rotation of the airflow. Traditional cyclone dust collectors mostly adopt a vertical structure, where the dust-laden airflow enters the cylinder tangentially from the inlet, forming a rotating vortex. Under centrifugal force, the dust is thrown against the cylinder wall and slides down the conical hopper to the collection device. However, this design has significant drawbacks: because the airflow needs to rotate along the inner wall of the conical hopper for a long time to reach the bottom for discharge, the hopper wall surface is continuously subjected to the scouring of high-speed dust particles, especially when dealing with highly abrasive gases. When dealing with media such as slag and metal dust, the cone bucket is prone to localized wear and even perforation, requiring frequent shutdowns for replacement, significantly increasing maintenance costs and affecting production efficiency. In addition, the complex airflow path in traditional devices (such as relying on multiple 90° bends for airflow guidance) further increases wind resistance and reduces dust removal efficiency. Although the industry has tried to alleviate the wear problem by thickening the cone bucket wall or using wear-resistant materials, it has failed to fundamentally change the continuous impact mode of airflow on the cone bucket. Therefore, how to optimize the airflow path to reduce cone bucket wear while taking into account both dust removal efficiency and ease of maintenance has become a core technical challenge that urgently needs to be solved in this field. Utility Model Content

[0003] This invention addresses the shortcomings of existing dust collectors, which suffer from continuous impact on the cone, easily causing wear and tear on the cone. It provides a horizontal cyclone treatment device.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a horizontal cyclone treatment device, comprising a cylinder and a cone connected to the bottom of the cylinder for collecting dust, wherein the cylinder is provided with an air inlet for introducing dust-laden airflow and an air outlet for discharging air, and a baffle is provided inside the cylinder at a position opposite to the air inlet, the baffle being used to cut off the airflow rotation path and guide the dust to fall directly into the cone.

[0005] By adopting the above technical solution, the horizontal cyclone treatment device cuts off the airflow rotation path through the baffle set inside the cylinder, directly guiding the dust to fall into the cone. This changes the way the airflow continuously rotates to the bottom of the cone in the traditional cyclone dust collector, significantly reducing the continuous scouring of the cone wall by the airflow, thus avoiding the problem of the cone being worn through. At the same time, because the dust is directly separated and falls, the rotational resistance of the airflow inside the cylinder is reduced, the overall wind resistance is lowered, and the dust removal efficiency is optimized. In addition, the structural design of the baffle simplifies the airflow path, reduces the need for complex accessories such as 90° elbows required in traditional devices, and lowers manufacturing costs and maintenance difficulty.

[0006] The present invention is further configured such that: the baffle includes a connecting section and a wind-blocking section, the wind-blocking section is in the shape of a straight plate and the straight direction of the wind-blocking section is perpendicular to the center of the cylinder.

[0007] By adopting the above technical solution, the straight-plate windbreak section is set perpendicular to the center of the cylinder. Its straight-line design can effectively block the disordered rotation of the airflow, forming a stable airflow cross-section, forcing the dust to fall directly after separation due to inertia. At the same time, the straight plate structure simplifies the manufacturing process and reduces processing costs. Moreover, its arrangement perpendicular to the cylinder can avoid the formation of secondary eddies on the surface of the baffle, reducing energy loss and further improving dust separation efficiency. In addition, the combination of the straight-plate windbreak section and the connecting section enhances the rigidity of the overall structure, making it suitable for high flow rate or high dust concentration conditions and extending the service life of the device.

[0008] The present invention is further configured such that: the baffle includes a connecting section and a wind-blocking section, the wind-blocking section is in the shape of an arc plate, and the arc curvature of the wind-blocking section is set to match the vortex trajectory of the dust-laden airflow.

[0009] By adopting the above technical solution, the curvature of the arc-shaped windbreak section matches the vortex trajectory of the dust-laden airflow, which can follow the natural rotation path of the airflow and guide the dust to be separated efficiently along the arc-shaped surface, reducing the energy loss caused by the airflow impacting the straight plate. The arc-shaped design can also extend the contact time between dust and airflow, enhance the inertial separation effect, and thus improve the dust removal efficiency. At the same time, the matching of the arc-shaped windbreak section with the vortex trajectory reduces the turbulence of the airflow in the cylinder and reduces local wear, which is especially suitable for handling sticky dust or high-temperature gas. In addition, the streamlined design of the arc-shaped structure further reduces wind resistance, making the device more energy-efficient.

[0010] The present invention is further configured such that the connecting section is detachably connected to the cylinder.

[0011] By adopting the above technical solution, the detachable connection method allows the connecting section of the baffle to be quickly separated from the cylinder, which facilitates the cleaning, replacement or maintenance of the baffle and reduces downtime caused by baffle wear or blockage. At the same time, the detachable design allows for flexible adjustment of the baffle type (such as straight plate or curved plate) according to actual working conditions, which improves the adaptability of the device. In addition, the modular connection structure reduces maintenance costs and allows for the replacement of partial components without disassembling the entire device, which is especially suitable for industrial scenarios that require frequent maintenance.

[0012] The present invention is further configured such that the axis of the air inlet is inclined at an angle to the axis of the cylinder, the inclination angle being 45° to 90°.

[0013] By adopting the above technical solution, the axis of the air inlet is set at an angle of 45° to 90° with the axis of the cylinder. The angle of inclination optimizes the incident direction of the dust-laden airflow, so that the airflow forms a more stable vortex after entering the cylinder, reducing the collision loss between the airflow and the inner wall of the cylinder. The selection of the angle range takes into account both the uniformity of airflow distribution and the compactness of the device. A larger angle, such as close to 90°, can form a strong vortex and enhance the dust separation capability, while a smaller angle, such as 45°, is suitable for low flow rate scenarios to reduce wind resistance. In addition, the design of the inclined air inlet avoids the problem of local airflow accumulation caused by traditional horizontal air inlet, reduces pressure fluctuations inside the cylinder, and improves the stability of the device operation.

[0014] The present invention is further configured such that the inner wall of the cone is covered with a wear-resistant coating.

[0015] The present invention is further configured such that the thickness of the wear-resistant coating is 2-5 mm.

[0016] By adopting the above technical solution, the inner wall of the cone is covered with a wear-resistant coating, the thickness of which is limited to 2-5mm. Through precise control of the thickness range, the coating can fully protect the inner wall of the cone, avoiding rapid wear and failure due to excessive thinness. The high hardness and corrosion resistance of the coating effectively resist the continuous impact of dust particles and chemical corrosion, significantly extending the service life of the cone and reducing the need for frequent replacement due to wear. The wear-resistant coating can also reduce the adhesion rate of dust on the inner wall of the cone, preventing dust accumulation and blockage, and ensuring that dust falls smoothly into the collection device. In addition, the application of the coating simplifies the maintenance process of the cone, requiring only periodic checks of the coating condition, without the need for frequent repairs of the inner wall. It is especially suitable for handling highly abrasive media such as metal dust and slag, greatly reducing operation and maintenance costs.

[0017] The present invention is further configured such that: the side wall of the cone bucket is provided with an inspection port, and the inspection port is equipped with a detachable cover plate.

[0018] By adopting the above technical solutions, the design of the inspection port on the side wall of the cone bucket and the removable cover plate allows operators to directly inspect the internal dust accumulation or perform cleaning and maintenance without disassembling the cone bucket, significantly improving maintenance convenience. The optimized location of the inspection port can cover the areas of the cone bucket that are prone to blockage or wear, facilitating targeted treatment. The removable cover plate adopts a sealed structure design to ensure that dust leakage is prevented when closed. At the same time, the quick opening and closing mechanism of the cover plate reduces maintenance time, making it particularly suitable for industrial environments with continuous production. In addition, the inspection port can also be used to install sensors to monitor the internal status, enabling preventive maintenance and further improving the reliability of the equipment operation.

[0019] This utility model, by adopting the above technical solutions, has significant technical effects: The horizontal cyclone treatment device, through the coordinated design of the cylinder, baffles, cone, and auxiliary structures, forms a highly efficient, durable, and easy-to-maintain dust removal system. Its overall solution significantly solves the problems of easy wear of the cone, high wind resistance, and complex maintenance in traditional cyclone dust collectors. Specifically, by cutting off the airflow rotation path and guiding dust directly downwards through the baffles, the continuous scouring of the cone by the airflow is greatly reduced. Combined with the wear-resistant coating design on the inner wall of the cone, the service life of the cone is significantly extended, avoiding the risk of wear through. The detachable connection method of the baffles, and the design of straight or curved access ports on the side wall of the cone, realizes modular design. This device features streamlined maintenance, reduced downtime, and improved ease of operation. The inlet's tilt angle, ranging from 45° to 90°, optimizes airflow distribution, reduces turbulence and energy loss, and adapts to various operating conditions. The straight baffle section enhances stability in high-velocity environments through rigid cutoff, while the curved baffle section improves dust separation efficiency and reduces wind resistance through curvature matching. Flange connections and gasket designs ensure airtightness and prevent dust leakage. These combined technical features significantly improve dust removal efficiency, operational stability, service life, and maintenance costs. It is particularly suitable for industrial environments with highly abrasive dust, continuous production, or complex operating conditions, and has broad application value.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0026] Example 1:

[0027] A horizontal cyclone treatment device includes a horizontally arranged cylinder 1 and a conical hopper 2 connected to the bottom of the cylinder 1 for collecting dust. One end of the cylinder 1 has an air inlet 3 for introducing dust-laden airflow. The cylinder 1 also has an air outlet 4, which is circular and whose central axis coincides with the central axis of the cylinder 1. The opening direction of the air outlet 4 is perpendicular to the inlet direction of the air inlet 3. Inside the cylinder 1, a baffle 5 is positioned opposite the air inlet 3 to cut off the airflow rotation path and guide the dust directly to fall into the conical hopper 2. The baffle 5 includes a connecting section 51 and a wind-blocking section 52. The connecting section 51 is straight and tangential to the outer ring of the air outlet 4. The wind-blocking section 52 is a straight line and its straight direction is perpendicular to the center of the air outlet 4. The connecting section 51 is detachably connected to the cylinder 1 for easy maintenance or replacement. The arrangement of the baffle 5 causes the dust-laden airflow to form a vortex after entering the cylinder 1 and impact the baffle 5. The dust is separated by inertia and falls directly into the cone hopper 2, avoiding the continuous rotation of the airflow that would cause wear to the cone hopper 2.

[0028] The axis of the air inlet 3 is set at an inclined angle to the axis of the cylinder 1, and the inclined angle ranges from 45° to 90° to optimize airflow distribution and reduce wind resistance. In this embodiment, the axis of the air inlet 3 is at 90° to the axis of the cylinder 1. The inner wall of the cone 2 is covered with a wear-resistant coating with a thickness of 2-5mm to extend service life and prevent wear through.

[0029] A dust outlet 8 is provided at the bottom of the cone bucket 2. The dust outlet 8 is used to discharge dust. The cone bucket 2 is also provided with an inspection port 6 and a removable cover plate 7 to facilitate the inspection and cleaning of the internal structure. When the dust outlet 8 is blocked, the cover plate 7 can be removed and the dust can be manually discharged and the dust outlet 8 can be cleared through the inspection port 6.

[0030] Example 2:

[0031] The difference between this embodiment and Embodiment 1 lies in the structure of the windbreak section 52. In this embodiment, the windbreak section 52 is arc-shaped and its curvature matches the vortex trajectory of the dust-laden airflow to enhance dust separation efficiency. By matching the curvature of the arc-shaped windbreak section 52 with the vortex trajectory of the dust-laden airflow, it can follow the natural rotation path of the airflow, guide the dust to separate efficiently along the arc-shaped surface, reduce the energy loss caused by the airflow hitting the straight plate, and the arc-shaped design can also prolong the contact time between the dust and the airflow, enhancing the inertial separation effect.
