Description

Technical Field

[0001] The present disclosure relates to the technical field of mechanical equipment maintenance, and in particular to a cleaning device for a coal feeder observation window. Background Art

[0002] During the process of adjusting the coal feed rate, the coal feeder is prone to malfunctions such as conveyor belt damage, deviation, or coal breakage. An observation window is installed on the rear door of the coal feeder to check the internal operating status of the coal feeder. Because the coal feeder is under constant positive pressure, a large amount of dust often adheres to the inner glass surface of the observation window, which hinders inspection work.

[0003] In the related art, the coal feeder can be shut down first, and then the observation window can be opened to clean the inner glass. However, this method affects the working efficiency of the coal feeder and cannot effectively clean the observation window in a timely manner while the coal feeder is running. In other solutions, a rotating handle is set to connect the inner and outer sides of the observation window, and the handle is shaken on the outside of the observation window for synchronous cleaning. However, this solution can only continuously accumulate dust attached to the glass surface in one rotation direction and cannot effectively remove the dust. Therefore, the cleaning effect is poor, and the dust remaining on the glass surface will still affect the inspection effect of the internal situation of the coal feeder. Utility Model Content

DETAILED DESCRIPTION

[0026] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0027] In the present disclosure, unless otherwise specified, directional words such as "inside" and "outside" refer to the inside and outside of the relative contours of the relevant components in actual use. For example, in the present application, the inner surface of the observation window refers to the surface located inside the coal feeder when the observation window is installed on the coal feeder. Correspondingly, the outer surface of the observation window refers to the surface of the observation window located outside the coal feeder.

[0028] Furthermore, the adjectives “first,” “second,” etc., used in the present disclosure are intended to distinguish one element from another and do not have any meaning of order or importance.

[0029] The present invention provides a cleaning device for a coal feeder observation window, referring to Figures 1 to 4The cleaning device includes a cleaning assembly and a dust collection assembly 5. The cleaning assembly may include a connecting shaft 2, a cleaning plate 3, and a handle 4. The cleaning plate 3 may be fixed to one end of the connecting shaft 2, and the handle 4 may be detachably connected to the other end of the connecting shaft 2. The connecting shaft 2 is rotatably mounted at the through-hole of the observation window 1, so that the handle 4 can drive the cleaning plate 3 to rotate via the connecting shaft 2, thereby covering and cleaning the inner surface 12 of the observation window 1 through the rotational action. At the same time, a first cavity 21 may be formed inside the connecting shaft 2, and the dust collection assembly 5 may be connected to the connecting shaft 2 and communicate with the first cavity 21. A suction hole 31 may be formed on the side of the cleaning plate 3 opposite to the inner surface 12. The cleaning plate 3 may have a second cavity 32 communicating with the suction hole 31 and the first cavity 21, so that the dust collection assembly 5 can sequentially absorb dust on the inner surface 12 of the observation window 1 through the first cavity 21, the second cavity 32, and the suction hole 31, thereby effectively cleaning the inner surface 12 and facilitating the staff to observe and inspect the interior of the coal feeder from the outer surface 11 of the observation window 1.

[0030] Through the above technical solution, the staff can shake the handle 4 from the outside of the observation window 1 to rotate the connecting shaft 2 that passes through the observation window 1, and control the cleaning plate 3 located on the inner surface 12 of the observation window 1 to rotate through the connecting shaft 2 to clean the dust. During this process, the dust collection component 5 located outside the observation window 1 can adsorb the dust on the inner surface 12 of the observation window 1 through the cavity formed in the connecting shaft 2 and the cleaning plate 3, so that the dust on the inner surface is directly sucked away after cleaning, and will not accumulate on the inner surface of the observation window, so as to improve the dust cleaning effect on the inner surface 12 of the observation window 1.

[0031] In some embodiments, reference Figure 1 and Figure 3 , the connecting shaft 2 can be at least partially protruded from the outer surface 11 of the observation window 1, and the portion of the connecting shaft 2 protruding from the outer surface 11 can protrude radially to form a stop portion 22. The stop portion 22 can be used to limit the connection with the cleaning plate 3 to stop the connecting shaft 2 at the through hole, so that the observation window 1 can be located in the accommodation gap between the stop portion 22 and the cleaning plate 3, preventing the connecting shaft 2 from driving the cleaning plate 3 to slide and disengage in the direction of the inner surface 12 of the observation window 1. In the embodiment where only the stop limit is considered, the connecting shaft 2 and the cleaning plate 3 can be a split structure, which is fixed after being installed to the observation window 1 to complete the assembly. In the embodiment described below where the stop portion 22 is rotatable relative to the connecting shaft 2, the connecting shaft 2 and the cleaning plate 3 can be fixedly connected, and the stop portion 22 is installed after being installed to the observation window 1. The latter will be specifically described below as an example.

[0032] In the above embodiment, the stopper 22 can be configured as an annular structure larger than the diameter of the through-hole of the observation window 1 to prevent the connecting shaft 2 from slipping out of the through-hole. The stopper 22 can effectively limit the connecting shaft 2 outside the observation window 1. At the same time, the cleaning plate 3 can also provide a limiting effect on the inside of the observation window 1, thereby preventing the connecting shaft 2 from undergoing significant axial displacement when installed in the through-hole, thereby ensuring the stability of the cleaning device.

[0033] In some embodiments, a bearing can be fixedly installed in the through hole, the outer ring of the bearing can be fixedly connected to the hole wall of the through hole, and the connecting shaft 2 can be fixedly connected to the inner ring of the bearing, so that the connecting shaft 2 can rotate relative to the observation window 1 through the bearing.

[0034] For example, a cover may be provided at one end of the bearing close to the inner surface 12 to prevent dust generated inside the coal feeder from entering the interior of the bearing (between the inner ring and the outer ring), preventing the interference of dust from reducing the lubrication of the bearing or clogging the bearing, thereby affecting the free rotation of the connecting shaft 2 and hindering the normal cleaning of the observation window 1 by the cleaning device.

[0035] In some embodiments, reference Figure 3 and Figure 5 The number of suction holes 31 can be multiple, and the multiple suction holes 31 can be evenly spaced apart on the side of the cleaning plate 3 opposite the inner surface 12. The suction holes 31 can be evenly spaced apart to form a straight line along the extension direction of the cleaning plate 3, so that after the dust collection assembly 5 is turned on, the suction holes 31 on the cleaning plate 3 can absorb dust at least within the diameter range of the observation window 1. When the cleaning plate 3 rotates driven by the connecting shaft 2, the suction range of the suction holes 31 can cover at least the inner surface 12 of the observation window 1, thereby achieving comprehensive cleaning of the inner surface 12 of the observation window 1.

[0036] In some embodiments, reference Figure 5 and Figure 6 One end of the handle 4 may be provided with a special-shaped connector 41, and the end of the connecting shaft 2 connected to the handle 4 may be provided with a positioning groove for inserting the special-shaped connector 41, wherein a special-shaped notch 23 that is adapted to the shape of the special-shaped connector 41 may be provided in the positioning groove, so that after the handle 4 is inserted into the positioning groove, the special-shaped connector 41 can be fixedly connected with the special-shaped notch 23 in a shape-adapted manner, and relative displacement is not easily generated at least in the circumferential direction of the connecting shaft 2, so that the use of the handle is stable and reliable. It should be noted that this embodiment does not impose any specific restrictions on the shape setting of the special-shaped connector 41 and the special-shaped notch 23, including but not limited to the use of special-shaped structures such as cross-shaped, conical, tooth-shaped or corrugated shapes, which can be selected according to actual usage and will not be described in detail here.

[0037] For example, refer to Figure 4A magnetic block 24 can be fixedly provided at the bottom of the special-shaped notch 23 to attract and fix the special-shaped connector 41 when it is inserted, thereby strengthening the assembly strength between the handle 4 and the connecting shaft 2 in the axial direction, making it difficult for the handle 4 to fall off in the axial direction of the connecting shaft 2. When it is necessary to remove the handle 4 from the connecting shaft 2, it is only necessary to apply a force slightly greater than the magnetic attraction between the magnetic block 24 and the special-shaped connector 41 in the axial direction away from the connecting shaft 2. This facilitates removal and is beneficial for removing the handle 4 after cleaning the inner surface 12 of the observation window 1, thereby reducing obstruction to the worker's field of vision and affecting the worker's observation and inspection of the internal conditions of the coal feeder.

[0038] In some embodiments, reference Figure 3 and Figure 4 The dust collection assembly 5 may include a dust collection member 51 and a dust conveying pipe 52, wherein one end of the dust conveying pipe 52 may be connected to the dust collection member 51, and the other end may be in communication with the first cavity 21 of the connecting shaft 2. In this embodiment, the dust collection member 51 may be connected to the first cavity 21 via the dust conveying pipe 52. The dust collection member 51 may be used to provide suction force and absorb dust located on the inner surface 12 of the observation window 1 through the dust conveying pipe 52 via the first cavity 21, thereby achieving a cleaning effect on the inner surface 12 of the observation window 1.

[0039] For example, refer to Figure 3 and Figure 4 The stopper 22 may have a third cavity 221 formed inside thereof, which communicates with the first cavity 21. The outer peripheral wall of the stopper 22 may be provided with an interface 222 communicating with the third cavity 221. The dust conveying pipe 52 may be sealedly connected to the interface 222, so that the dust collection assembly 5 can sequentially form a suction channel with the suction hole 31 on the cleaning plate 3 through the dust conveying pipe 52, the third cavity 221, and the first cavity 21. At the same time, the stopper 22 is rotatably connected to the connecting shaft 2, so that when the connecting shaft 2 is rotated by the handle 4, the stopper 22 and the connecting shaft 2 can form a relative rotational motion, thereby preventing the dust collection assembly 5 from being rotated by the connecting shaft 2, thereby ensuring a stable dust collection effect of the dust collection assembly 5.

[0040] In the above embodiment, the spatial volume of the third cavity 221 can be larger than the spatial volume of the first cavity 21, so that the third cavity 221 can be formed into a temporary storage space for dust, used to store and buffer dust when the dust collecting member 51 absorbs dust, ensure the consistency of dust absorption, and improve the dust absorption effect and the cleaning effect of the observation window 1. At the same time, this embodiment does not impose specific restrictions on the sealing connection between the dust conveying pipe 52 and the interface 222, including but not limited to using methods such as threaded connection, snap-on connection, bonding, or welding. It only needs to ensure that the sealing effect after the two are connected meets the standard for preventing dust leakage, which is not detailed here.

[0041] In some embodiments, reference Figure 1 and Figure 2 A positioning ring 6 may be provided around the periphery of the observation window 1, and the observation window 1 may be connected to the tail end of the coal feeder via the positioning ring 6. In this embodiment, the positioning ring 6 can stably connect the observation window 1 to the tail end of the coal feeder, including but not limited to methods such as bonding or clamping, which are not specifically limited in this embodiment. Furthermore, after the observation window 1 is positioned at the tail end of the coal feeder via the positioning ring 6, the fixing therebetween may be further strengthened by bolts or other means to ensure the stability of the observation window 1 on the coal feeder.

[0042] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0043] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0044] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
