Description

Technical Field

[0001] This invention relates to a purging device for the oil nozzle of a sintering machine wheel. Background Technology

[0002] During the production process of the sintering machine, the sintering machine trolley needs to maintain continuous operation. Due to the harsh working conditions such as high temperature, heavy load, impact vibration, dust erosion and water spray during the operation of the sintering machine trolley, the bearing wear is accelerated, and the requirements for lubricating grease replenishment are high.

[0003] During the sintering process, the sintering machine trolley needs to maintain continuous operation. Due to the trolley wheels being exposed to harsh conditions such as high temperature, heavy load, impact vibration, dust erosion, and water spray for a long time, the bearing wear is accelerated, and the requirements for the frequency and cleanliness of grease replenishment are extremely high.

[0004] In recent years, with the development of automatic lubrication technology, many sintering plants have adopted automatic lubrication devices to lubricate wheels. However, after lubrication, grease often remains on the wheel grease nozzles, which can easily form oil stains and hard lumps during subsequent operation, affecting the normal operation of the next automatic lubrication, and even clogging the grease nozzles or contaminating the bearings.

[0005] Currently, the common method is manual spot cleaning, but it has the following drawbacks: low efficiency and high labor intensity; it cannot achieve continuous operation and has poor coordination with automatic refueling systems; manual operation poses safety hazards.

[0006] Some companies have tried using electric brushes or fixed-point air blowing for cleaning, but due to the common phenomenon of deviation during the operation of sintering trolleys, the fixed-point cleaning method cannot adapt to the deviation of the trolley position, resulting in the following problems: the cleaning function fails when the trolley is far away from the cleaning area; when the trolley is close, the cleaning device is easily damaged by the impact of the wheels, resulting in poor reliability.

[0007] Therefore, there is an urgent need for a purging device that can adapt to the trolley position deviation, continuously and efficiently remove residual grease from the nozzle, and has a simple and reliable structure, in order to solve the above-mentioned technical problems. Summary of the Invention

[0008] To solve the above technical problems, the present invention provides a purging device for the oil nozzle of a sintering machine wheel, which can adapt to changes in wheel position during continuous operation of the trolley, efficiently purge residual grease from the oil nozzle, and ensure the stable operation of the automatic refueling system.

[0009] To achieve the above objectives, the purging device for the sintering machine wheel oil nozzle of the present invention includes: a fixed base (1), a rotating seat (2), an elastic element (3), a rotating component (4), a first limiting block (51), and a blowing air pipe (60); wherein, The rotating seat (2) is disposed on the upper end of the fixed base (1); The rotating component (4) is rotatably mounted on the rotating base (2); The elastic element (3) is disposed between the rotating component (4) and the rotating seat (2) to provide a reset torque; The first limiting block (51) is respectively provided on one side of the rotating component; A blower pipe is provided on the rotating component; Without external force, the rotating component abuts against the first limiting block under the action of the elastic element, and the blowing air pipe is perpendicular to the direction of wheel travel under the drive of the rotating component.

[0010] Furthermore, a second limiting block is provided at a predetermined phase angle from the first limiting block, so that the rotating component (4) can rotate relative to the rotating seat (2) by a maximum rotation angle of 90°.

[0011] Furthermore, the front end of the blowing air pipe (60) is provided with an air nozzle (61), and the end is connected to the air supply circuit (62).

[0012] Furthermore, the first limiting block is provided with a buffer pad to absorb the impact energy when the rotating component is struck.

[0013] Furthermore, the nozzle is a flat, fan-shaped nozzle with an adjustable blowing angle.

[0014] Furthermore, the elastic element (3) is a torsion spring.

[0015] Compared with the prior art, the present invention has the following significant advantages: Highly adaptable: Through the cooperation of rotating parts and elastic elements, the air nozzle can automatically adjust its angle as the trolley deviates, always aligning with the oil nozzle area, and achieving dynamic following and blowing. Continuous and efficient: It can clean in real time during the operation of the trolley, significantly improving work efficiency; Simple and reliable structure: pure mechanical and pneumatic structure, no electric parts, high temperature resistance, dust resistance, maintenance-free, and long service life; High safety: Equipped with limit blocks and buffer pads to prevent impact damage and ensure equipment safety; High compatibility: It can be seamlessly integrated with existing automatic refueling systems to work together and improve the overall stability of the lubrication system.

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0021] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] like Figure 1 As shown, the sintering machine wheel oil nozzle blowing device of the present invention aims to use the characteristic that the rotating component can adaptively rotate with the change of the trolley position to blow and clean the oil nozzle of the trolley wheel in operation using an air nozzle.

[0025] Includes: a fixed base (1), a rotating seat (2), an elastic element (3), a rotating component (4), a first limiting block, and a jetting air pipe (60); wherein, The fixed base (1) is installed on the side of the trolley wheel for overall support and positioning; The rotating seat (2) is disposed on the upper end of the fixed base (1); The rotating component (4) is rotatably mounted on the rotating seat (2); as shown in the figure, the rotating component is a strip arm, one end of which is connected to the rotating seat via a pivot; the elastic element (3) is disposed between the rotating component (4) and the rotating seat (2) to provide a reset torque; the elastic element (3) shown in the figure is a torsion spring.

[0026] The first limiting blocks are respectively provided on one side of the rotating component; A blower pipe (60) is provided on the rotating component. Without external force, the rotating component abuts against the first limiting block under the action of the elastic element, and the blowing air pipe is perpendicular to the direction of wheel travel under the drive of the rotating component.

[0027] Working principle: such as Figures 2 to 4 As shown, when the trolley (71) moves forward, the wheel (72) first contacts the air nozzle (61) of the purging device, as... Figure 2 As shown. Then the wheel (72) pushes the air nozzle (61) and the rotating component (4) to rotate around the axis, as... Figure 3 As shown. When the wheel (72) continues to move forward, the air nozzle (61) slides on the wheel (72) and gradually approaches the oil nozzle (73). At this time, the air supply circuit (62) starts to supply air until the air nozzle (61) passes the oil nozzle (73), completing the purging of the oil nozzle (73) of a single wheel.

[0028] Example 1: As attached Figures 1 to 4 As shown, a purging device for the oil nozzle of a sintering machine wheel in this embodiment includes: a fixed base (1), a rotating seat (2), an elastic element (3), a rotating component (4), a first limiting block (51), a second limiting block (52), a blowing air pipe (60), an air nozzle (61), an air supply circuit (62), and an air supply circuit pipeline bracket (63).

[0029] The air nozzle (61) is a flat fan-shaped nozzle with an adjustable blowing angle to improve the cleaning coverage.

[0030] The elastic element (3) is a torsion spring or a disc spring, which has a good fatigue life and is suitable for high-frequency vibration environments.

[0031] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the embodiments described above. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
