Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, and in particular to a dust removal device for oxidized pellet production. Background Technology

[0002] Dust removal equipment for oxidized pellet production is used to remove pollutants such as dust and particulate matter from waste gas during the oxidized pellet production process, thereby purifying the air, protecting the environment, and ensuring the normal operation of production equipment. Common types include baghouse dust collectors, which use fiber filter bags to filter dust-laden gas, effectively filtering through the dust layer formed on the surface of the filter bags. They have advantages such as high dust removal efficiency and good capture effect for fine dust. Electrostatic precipitators use a high-voltage electric field to charge dust particles and adsorb them onto the dust collection plate. They feature large air volume handling capacity, low resistance, and the ability to handle high-temperature and corrosive gases. Cyclone dust collectors rely on the centrifugal force generated by the rotation of dust-laden gas within the cyclone to separate dust particles. They are simple in structure, low in cost, and easy to maintain, and are suitable for separating larger dust particles. Wet scrubbers work by contacting dust-laden gas with a liquid (usually water), allowing the dust to be captured by the liquid. They can remove some gaseous pollutants simultaneously, but generate wastewater that requires treatment. These dust removal devices can be used individually or in combination, depending on factors such as the oxidized pellet production process, dust characteristics, and environmental protection requirements.

[0003] The dust removal equipment currently used in the production of oxidized pellets has certain limitations. Most existing dust removal equipment is designed as a single, integrated structure. While this integrated design ensures the integrity and stability of the equipment to a certain extent, it brings many inconveniences to actual use. When disassembly and maintenance are required, due to the characteristics of its integrated structure, it is difficult for workers to quickly and easily conduct in-depth inspections and maintenance operations on the internal parts of the equipment, requiring a significant amount of time and effort to complete the disassembly and reassembly. Moreover, this inconvenience in disassembly and maintenance prevents the equipment from being flexibly adjusted and optimized according to actual conditions during daily use, thus affecting the efficiency of the entire dust removal operation, making it inconvenient to use, and failing to meet the requirements of efficient and stable operation in oxidized pellet production.

[0004] Therefore, those skilled in the art have provided a dust removal device for oxidized pellet production to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dust removal device for oxidized pellet production that is easier to maintain.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A dust removal device for oxidized pellet production includes:

[0008] The dust removal body includes a cyclone dust collector, and an adjusting gear is sleeved on the outer surface of the cyclone dust collector;

[0009] The support mechanism includes a side support plate. A connecting motor is fixed to one outer side of the side support plate via a fixing plate, and a gear is fixedly connected to the output end of the connecting motor. A positioning bearing and a reinforcing support plate are fixed inside the side support plate from top to bottom.

[0010] Furthermore, the reinforcing support plate has a conical support hole inside, and the lower part of the cyclone dust collector is located inside the conical support hole.

[0011] Furthermore, the inner surface of the conical support hole that contacts the outer surface of the cyclone dust collector is coated with a wear-resistant coating.

[0012] Furthermore, the positioning bearing is fixed to the side support plate by bolts, and the interior of the positioning bearing is fixed to the outer surface of the cyclone dust collector.

[0013] Furthermore, the fixed connecting gear meshes with the adjusting gear, the connecting motor is connected to an external power supply and a controller, and the connecting motor is preferably a hysteresis synchronous motor or a stepper motor.

[0014] Furthermore, a support leg is fixedly connected to the lower end of the side support plate, and a lower base is fixed to the lower end of the support leg, with the lower base in contact with the ground.

[0015] This utility model has the following beneficial effects:

[0016] This utility model proposes a dust removal device for oxidized pellet production. Through a modular design of the dust removal body and support mechanism, this dust removal device enables rapid disassembly and maintenance of key components. The dust removal body can be lifted simply by loosening the positioning bearing bolts, solving the problems of difficult maintenance and long downtime associated with traditional integrated equipment. This improves production line efficiency. The motor-driven gear rotation structure allows the cyclone dust collector to freely adjust its angle, flexibly adapting to different pipeline layout requirements. This avoids repeated disassembly and assembly due to pipeline misalignment, significantly improving operational convenience and compatibility. Furthermore, the top positioning bearing provides axial constraint, the central tapered support hole achieves self-centering support and is equipped with a wear-resistant coating to reduce rotational wear, and the bottom support legs and lower base ensure overall stability, increasing overall stability.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-4 One embodiment of this utility model is a dust removal device for oxidized pellet production, comprising: a dust removal body 1 and a support mechanism 2.

[0025] The advantage of this dust removal equipment lies in overcoming the limitations of traditional integrated structures by adopting a modular, split design. The equipment separates the dust removal body 1 and the support mechanism 2 as two independent modules through a detachable mechanical connection. The dust removal body 1 includes the cyclone dust collector 11 and an adjusting gear 12 fitted onto its outer surface, while the support mechanism 2 consists of components such as a side support plate 22, a positioning bearing 21, and a reinforcing support plate 26. When maintenance is required, only the fixing bolts of the positioning bearing 21 and the side support plate 22 need to be removed, allowing the dust removal body 1 to be moved entirely using lifting equipment. This separate structure overcomes the disadvantage of integrated equipment being difficult to inspect thoroughly, reduces maintenance time and labor costs, and effectively improves the operational continuity of the oxidized pellet production line.

[0026] The device features a rotary adjustment structure. The connecting motor 24 is mounted on the outside of the side support plate 22 via a fixing plate 25, and its output shaft directly drives the connecting gear 23 to rotate. This connecting gear 23 forms a precise meshing relationship with the adjusting gear 12 on the dust collector body 1, enabling the motor to drive the entire cyclone dust collector 11 to rotate axially during operation. The key design of using a hysteresis synchronous motor or stepper motor ensures that the equipment can automatically lock its position when stopped, preventing displacement due to gravity. This rotary function allows the equipment to flexibly adjust the angle and direction of the inlet and outlet air ducts according to on-site conditions, solving the problem of repeated disassembly and reassembly required by traditional equipment due to duct misalignment, greatly improving the convenience of maintenance and operation and the adaptability of the ducts.

[0027] The bottom of the cyclone dust collector 11 is embedded in a conical support hole 29 inside the support plate 26 of the support mechanism 2. This conical structure forms a self-centering physical limit, allowing the weight of the equipment to be evenly distributed to the support mechanism 2 through the conical contact surface. A wear-resistant coating is applied to the inner surface of the conical support hole 29, which effectively reduces frictional losses generated when the cyclone dust collector 11 rotates. The upper positioning bearing 21 is fixed to the side support plate 22 by bolts and sleeved onto the outer wall of the cyclone dust collector 11, forming an axial constraint. The grounded design of the bottom support legs 27 and the lower base 28 provides a stable foundation. This ensures the structural reliability and stability of the equipment during dynamic adjustment and long-term operation.

[0028] Working principle: When in use, the connecting motor 24 can be started to drive the connecting gear 23 to rotate, and then the cyclone dust collector 11 can be adjusted by adjusting the gear 12 to adjust the angle of the cyclone dust collector 11, which is convenient for connecting pipes and for pipe replacement and maintenance.

[0029] When disassembly is required, the entire dust collector body 1 and the support mechanism 2 can be separated by removing the bolts connecting the positioning bearing 21 and the side support plate 22. Then, the dust collector body 1 can be completely removed using lifting equipment without removing the support mechanism 2. The operation is simple and convenient.

[0030] During this process, the lower part of the cyclone dust collector 11 is inserted into the conical support hole 29 of the reinforcing support plate 26 to achieve the function of lifting and increase stability. The inner surface of the conical support hole 29 and the outer surface in contact with the cyclone dust collector 11 are coated with a wear-resistant coating to prevent the cyclone dust collector 11 from being worn and damaged during rotation. At the same time, a planetary reducer can be matched between the connecting motor 24 and the connecting gear 23 to increase stability. Furthermore, the hysteresis synchronous motor or stepper motor cannot rotate after stopping, which further increases stability.

[0031] 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.
