[0031] Please refer to Figure 1 and Figure 2 This embodiment provides a residual coal collection device, which includes a cleaning mechanism 10, a first conveying mechanism 20, and a hopper 30. The inlet of the first conveying mechanism 20 is connected to the cleaning mechanism 10, and the outlet of the first conveying mechanism 20 is connected to the hopper 30. The cleaning mechanism 10 is used to collect residual coal on the machine-side operating platform 210 of the coke oven 200 and transfer it to the first conveying mechanism 20. The first conveying mechanism 20 is used to transfer the residual coal into the hopper 30. The residual coal collection device can automatically clean and collect residual coal that has fallen from the machine side of the coke oven 200.

[0032] The cleaning mechanism 10 is used to collect excess coal from the coke oven 200's side operating platform 210 and transport it to the feed port of the first conveying mechanism 20. This facilitates the unified transport and collection of excess coal from the side operating platform 210. The present application does not limit the cleaning method of the cleaning mechanism 10, as long as it can collect excess coal from the side operating platform 210 and transport it to the feed port of the first conveying mechanism 20.

[0033] The first conveying mechanism 20 is used to convey the residual coal, so as to convey the residual coal from the feed port of the first conveying mechanism 20 to the discharge port of the first conveying mechanism 20. In this embodiment, the first conveying mechanism 20 is a screw conveyor, and of course it can also be a belt conveyor or the like.

[0034] The discharge port of the first conveying mechanism 20 is connected to the inlet port of the hopper 30. Thus, the first conveyor can convey the excess coal into the hopper 30, thereby collecting and storing the excess coal in the hopper 30. In this way, the excess coal in the hopper 30 can be regularly transferred by a transfer vehicle, and the excess coal on the machine-side operating table 210 can be promptly removed, keeping the machine-side operating table 210 clean.

[0035] In this embodiment, the hopper 30 has a receiving cavity, and the receiving cavity is configured in a conical shape. That is, the receiving cavity of the hopper 30 gradually converges from the inlet to the bottom of the receiving cavity. This facilitates the flow of excess coal into the hopper 30 along the cavity wall of the receiving cavity, thereby facilitating the collection of the excess coal. Of course, the conical receiving cavity is only an example of this application. In other embodiments, those skilled in the art may also configure the receiving cavity to be square based on the storage capacity requirements of the receiving cavity of the hopper 30.

[0036] It should also be noted that in this embodiment, the cleaning mechanism 10, first conveying mechanism 20, and hopper 30 are mounted on the coke pushing car 220. This allows the cleaning mechanism 10 to collect excess coal from the machine-side operating platform 210 by moving the coke pushing car 220. It should be understood that the cleaning mechanism 10, first conveying mechanism 20, and hopper 30 should be positioned on the coke pushing car 220 to avoid interfering with the excess coal collection process. For example, the cleaning side of the cleaning mechanism should be exposed to the coke pushing car 220.

[0037] In summary, this embodiment provides a residual coal collection device, which includes a cleaning mechanism 10, a first conveying mechanism 20, and a hopper 30. The feed port of the first conveying mechanism 20 is connected to the cleaning mechanism 10, and the discharge port of the first conveying mechanism 20 is connected to the hopper 30. The cleaning mechanism 10 is used to collect the residual coal on the machine-side operating table 210 of the coke oven 200 and transfer it to the first conveying mechanism 20. The first conveying mechanism 20 is used to transfer the residual coal into the hopper 30. In this way, during the residual coal collection process, the cleaning mechanism 10 can be used to clean and transfer the residual coal on the machine-side operating table 210 of the coke oven 200, so that the residual coal is transferred to the feed port of the first conveying mechanism 20 through the cleaning mechanism 10; then, the residual coal is transferred from the feed port of the first conveying mechanism 20 to the discharge port of the first conveying mechanism 20 through the first conveying mechanism 20, and then transferred from the discharge port of the first conveying mechanism 20 to the discharge port of the first conveying mechanism 20. In this way, the remaining coal on the machine side operating table 210 can be collected from the table top of the machine side operating table 210 into the hopper 30, so that the remaining coal on the machine side operating table 210 can be cleaned. Compared with the prior art which usually adopts a manual method to clean the scattered remaining coal on the machine side operating table 210, the automatic cleaning and collection method of the remaining coal in this application is not only simple in cleaning method, but also can reduce labor intensity and improve cleaning efficiency.

[0038] In order to avoid harm to the human body caused by dust generated during the residual coal collection process, optionally, in this embodiment, the residual coal collection device also includes a separator 40 and a centrifugal fan 50 connected to the separator 40, the separator 40 includes a first connection port 41 and a second connection port 42, the first connection port 41 is connected to the cleaning mechanism 10, and the second connection port 42 is connected to the hopper 30, the separator 40 is used to suck the powder generated by the cleaning mechanism 10 during the cleaning process into the separator 40 under the action of the centrifugal fan 50, and unload it into the hopper 30 through the second connection port 42.

[0039] Among them, the first connection port 41 of the separator 40 is connected to the cleaning mechanism 10. In this way, the dust generated when the cleaning mechanism 10 cleans the remaining coal can be sucked into the separator from the first connection port 41 through the negative pressure generated by the centrifugal fan 50, thereby effectively preventing the dust from flying everywhere and causing environmental pollution.

[0040] The second connection port 42 of the separator 40 is connected to the hopper 30. In this way, the dust generated by the cleaning mechanism 10 when collecting the residual coal can be discharged into the hopper 30 through the second connection port 42 after being deposited in the separator 40, thereby realizing the recovery of the dust. In this way, environmental pollution is reduced, and the residual coal collection rate is improved, thereby avoiding the waste of residual coal.

[0041] In this embodiment, a rotary sealing valve is optionally connected to the second connection port 42. Thus, in actual use, dust generated by the cleaning mechanism 10 when collecting residual coal can be first sucked into the separator 40, and after a certain period of sedimentation, the residual coal in the separator 40 can be discharged into the hopper 30 by controlling the rotary sealing valve, thereby further preventing dust from polluting the environment.

[0042] Please refer to Figure 3 and Figure 4 In this embodiment, optionally, the above-mentioned cleaning mechanism 10 may include a machine base 11, a second conveying mechanism 12 and a chute 13, the second conveying mechanism 12 is connected to the machine base 11, the chute 13 is connected to the bottom of the machine base 11, and the feed port of the chute 13 is connected to the discharge port of the second conveying mechanism 12, and the discharge port of the chute 13 is connected to the feed port of the first conveying mechanism 20.

[0043] The second conveying mechanism 12 is used to remove excess coal from the machine-side operating platform 210. The feed port of the chute 13 is connected to the discharge port of the second conveying mechanism 12, and the discharge port of the chute 13 is connected to the first conveying mechanism 20. In this way, excess coal collected by the second conveying mechanism 12 can enter the chute 13 from the discharge port of the second conveying mechanism 12, and then enter the first conveying mechanism 20 through the chute 13, thereby entering the hopper 30.

[0044] The chute 13 is connected to the bottom of the base 11, which makes it easier to transport the remaining coal. Figure 4 In this embodiment, the chute 13 gradually converges from the feed port to the discharge port of the chute 13, so that the residual coal can be conveniently transported in the chute 13, thereby improving the transmission efficiency of the residual coal.

[0045] In addition, it should be noted that the base 11 is used to connect the second conveying mechanism 12 and the slide bin 13 , wherein the bottom of the base 11 should have an opening for exposing the cleaning side of the second conveying mechanism 12 .

[0046] In order to further improve the cleaning quality of the residual coal collection device of the present application, optionally, in this embodiment, the second conveying mechanism 12 includes a second conveyor 121 and a third conveyor 122, the third conveyor 122 is located between the second conveyor 121 and the hopper 30, and the material conveying direction of the second conveyor 121 and the material conveying direction of the third conveyor 122 are both perpendicular to the moving direction a of the residual coal collection device.

[0047] In this way, during actual use, the remaining coal on the machine side operating table 210 can be collected first by the second conveyor 121, and then the remaining coal on the machine side operating table 210 can be collected for a second time by the third conveyor 122 located between the second conveyor 121 and the hopper 30. In this way, the remaining coal can be collected more comprehensively and thoroughly.

[0048] In addition, in this embodiment, the material conveying direction of the second conveyor 121 and the material conveying direction of the third conveyor 122 are both perpendicular to the moving direction a of the residual coal collection device, and the feed port of the second conveyor 121 is located on the side of the second conveyor 121 away from the third conveyor 122.

[0049] In order to facilitate the setting of the chute 13, optionally, the discharge port of the second conveyor 121 is located on the side of the second conveyor 121 close to the third conveyor 122, and the discharge port of the third conveyor 122 is located on the side of the third conveyor 122 close to the second conveyor 121, and the feed port of the chute 13 is provided between the second conveyor 121 and the third conveyor 122, and is respectively connected to the discharge port of the second conveyor 121 and the discharge port of the third conveyor 122.

[0050] In this embodiment, the cleaning mechanism 10 optionally further includes a rotating brush head 60, which is disposed in the machine base 11 and is located at the feed port of the third conveyor 122. Thus, the rotating brush head 60 can sweep the residual coal on the machine-side operating table 210, thereby pushing the residual coal to the feed port of the third conveyor 122, so that the residual coal enters from the feed port of the third conveyor 122 and is discharged from the discharge port of the third conveyor 122 to enter the chute 13.

[0051] It should be noted that in this embodiment, when the cleaning mechanism 10 is provided with a rotating brush head 60, the feed port of the third conveyor 122 is optionally located on a side of the third conveyor 122 away from the second conveyor 121. When the cleaning mechanism 10 is not provided with a rotating brush head 60, the feed port of the third conveyor 122 is located on a side of the third conveyor 122 closer to the second conveyor 121. In this way, the combination of the second conveyor 121 and the third conveyor 122 can further improve the cleaning efficiency of the residual coal.

[0052] Optionally, in this embodiment, the first conveying mechanism 20, the second conveyor 121 and the third conveyor 122 are all screw conveyors.

[0053] Furthermore, in this embodiment, a lifting mechanism is connected to the second conveying mechanism 12, and the lifting mechanism is used to drive the second conveying mechanism 12 toward or away from the machine-side operating platform 210. In this way, by controlling the lifting and lowering of the cleaning mechanism 10, damage to the cleaning mechanism 10 due to uneven ground or foreign objects during the material collection process can be avoided.

[0054] For example, in this embodiment, the above-mentioned lifting mechanism may include a rocker arm 71, a driving member 72, a first connecting rod 73 and a second connecting rod 74. The rocker arm 71 is bent, and the driving rod 721 of the driving member 72 is hinged to the first connecting rod 73. The end of the first connecting rod 73 away from the driving member 72 is hinged to the second connecting rod 74, and the end of the second connecting rod 74 away from the first connecting rod 73 is hinged to the rocker arm 71. The end of the rocker arm 71 away from the second connecting rod 74 is connected to the second conveying mechanism 12; the driving rod 721 is driven to move toward the moving direction a of the residual coal collection device, and the hinged ends of the first connecting rod 73 and the second connecting rod 74 are abutted against the bending part of the rocker arm 71 so that the rocker arm 71 drives the second conveying mechanism 12 away from the machine-side operating table 210. The driving rod 721 is driven to move in the opposite direction of the moving direction a of the residual coal collecting device, and the hinged ends of the first connecting rod 73 and the second connecting rod 74 are separated from the bending part of the rocker arm 71 so that the rocker arm 71 drives the second conveying mechanism 12 to gradually approach the machine side operating table 210.

[0055] So, please refer to Figure 3As shown, during the normal cleaning and collection process, the driving rod 721 of the driving member 72 is retracted, the first connecting rod 73 and the second connecting rod 74 are hinged, the second connecting rod 74 and the rocker arm 71 are hinged, and the cleaning mechanism 10 is in a lowered state; when the cleaning mechanism 10 needs to be lifted, the driving rod 721 of the driving member 72 is extended, and at this time, the first connecting rod 73 rotates, thereby driving the second connecting rod 74 to rotate, and then the hinge of the first connecting rod 73 and the second connecting rod 74 abuts against one side of the rocker arm 71, gradually lifting the rocker arm 71 until the hinge of the first connecting rod 73 and the second connecting rod 74 abuts against the bend of the rocker arm 71. Since the lifting state of the cleaning mechanism 10 from the lowered state is the reverse process of the above process, those skilled in the art can simply infer it through the description of the above process, so this application will not repeat it here.

[0056] In this embodiment, the rocker arm 71, the first connecting rod 73 and the second connecting rod 74 each include two groups, such as Figure 3 or Figure 4 shown.

[0057] In order to prevent the cleaning mechanism 10 from accidentally falling after being lifted by the lifting mechanism, in this embodiment, the residual coal collection device is further provided with a suspension mechanism, which can be located above the driving member 72. When the cleaning mechanism 10 is in the raised state, the suspension mechanism is used to lock the swing rod 71 of the cleaning mechanism 10 to prevent the swing rod 71 from falling. For example, the suspension mechanism can be a locking member, which can cooperate with the swing rod 71 to lock or unlock the swing rod 71.

[0058] In order to ensure that the rotating brush head 60 is in effective contact with the machine side operating table 210, thereby thoroughly cleaning the remaining coal on the machine side operating table 210, and at the same time to facilitate the replacement of the rotating brush head 60, in this embodiment, optionally, an adjusting rod 80 is connected to the machine base 11, and the rotating brush head 60 is connected to the adjusting rod 80, and the adjusting rod 80 is used to adjust the height of the rotating brush head 60 relative to the machine side operating table 210.

[0059] For example, the rotating brush head 60 can be slidably connected to the adjusting rod 80 through a connecting piece (i.e., one end of the connecting piece is connected to the rotating brush head 60, and the other end is slidably connected to the adjusting rod 80). By changing the position of the rotating brush head 60 on the adjusting rod 80, the height of the rotating brush head 60 relative to the machine-side operating table 210 can be adjusted. Of course, the rotating brush head 60 can also be screwed to the adjusting rod 80 through a connecting piece (i.e., the adjusting rod 80 is provided with an external thread, one end of the connecting piece is connected to the rotating brush head 60, and the other end is screwed to the adjusting rod 80). It should be understood that the above-mentioned sliding connection and screw connection are only two examples given in this application, and should not be regarded as a limitation on the adjustment method of the adjusting rod 80 of this application. In other embodiments, those skilled in the art can also adopt other adjustment methods to adjust the height of the rotating brush head 60, and this application does not impose any limitation.

[0060] The foregoing description is merely an optional embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.

[0061] 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 invention will not further describe various possible combinations.
