DETAILED DESCRIPTION
[0022] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0023] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.
[0024] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.
[0025] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.
[0026] The present application is further described below with reference to the accompanying drawings:
[0027] like Figures 1 to 5 As shown, the present application provides a sewage discharge mechanism, including a sewage discharge chassis 1, which is arranged under the conveyor belt 4. The sewage discharge chassis 1 is usually made of stainless steel and has high corrosion resistance. It can receive materials that accidentally fall from all around during the transportation of the conveyor belt 4, and guide and discharge the received materials.
[0028] The bottom of the sewage discharge chassis 1 is configured to be arc-shaped along the first direction, which can gather and collect the received materials, thereby further facilitating the discharge and reducing the accumulation of materials. Considering that the materials on the sewage discharge chassis 1 are usually discharged after flushing, the curvature of the bottom of the sewage discharge chassis 1 can be obtained and manufactured by discrete element simulation according to the actual accumulation angle of the water-containing material, so as to further reduce the probability of material accumulation.
[0029] In some embodiments, reinforcing ribs are provided under the bottom of the sewage discharge chassis 1 to improve the structural strength of the bottom of the sewage discharge chassis 1 and reduce the probability of deformation.
[0030] A sewage outlet 11 is provided on one side of the sewage discharge chassis 1 in the second direction, and the material in the sewage discharge chassis 1 can be discharged through the sewage outlet 11. A sewage hopper 2 is arranged at the sewage outlet 11 along the second direction. The sewage hopper 2 can guide the material discharged from the sewage outlet 11 to reduce the occurrence of material scattering. The bottom of the sewage hopper 2 is configured to be arc-shaped along the first direction. The curvature of the bottom of the sewage discharge chassis 1 is not greater than the curvature of the bottom of the sewage hopper 2. The sewage hopper 2 is at least connected with the lowest point of the bottom of the sewage discharge chassis 1 at the lowest point of the bottom, ensuring that the gathered materials can flow out from the sewage hopper 2 and will not be blocked by the structure of the sewage hopper 2 itself, thereby reducing the difficulty of sewage discharge, reducing dead corners, thereby reducing the occurrence of material accumulation, protecting the cleanliness of the sewage discharge chassis 1 and the sewage hopper 2, and reducing corrosion.
[0031] In the present application, the first direction generally refers to the width direction of the conveyor belt 4 , and the second direction generally refers to the conveying direction of the conveyor belt 4 . The materials dropped on both sides of the width of the conveyor belt 4 can be received, collected and gathered by the sewage discharge chassis 1 .
[0032] like Figure 2 In the embodiment shown, the curvature of the bottom of the sewage chassis 1 is equal to the curvature of the bottom of the sewage hopper 2, and the curvatures of the two match each other. In this case, the material convergence effects of the sewage chassis 1 and the sewage hopper 2 can be kept consistent, thereby achieving more stable guidance.
[0033] like Figure 2In the embodiment shown, the bottom of the sewage outlet 11 is aligned with the bottom of the sewage chassis 1, so that the bottom of the sewage chassis 1 and the bottom of the sewage hopper 2 can be connected almost seamlessly, thereby reducing the jamming and accumulation of materials when passing through, and improving the smoothness of sewage discharge. At the same time, this design reduces dead corners and can also facilitate cleaning, reducing the occurrence of material residues in dead corners.
[0034] like Figure 1 In the shown embodiment, a first flushing device 3 is provided on the sewage chassis 1 at a side away from the sewage outlet 11. The first flushing device 3 includes a first flushing channel 31 and a plurality of first flushing heads 32. The first flushing channel 31 penetrates the sewage chassis 1 along a first direction. The first flushing heads 32 are arranged at equal intervals on the first flushing channel 31. The flushing direction of the first flushing heads 32 is toward the sewage outlet 11. The first flushing heads 32 can spray flushing liquids such as clean water to flush and mix the materials collected in the sewage chassis 1, and flow them out to the sewage outlet 11.
[0035] like Figure 2 In the shown embodiment, waterproof baffles 12 are installed on both sides of the sewage discharge chassis 1 in the first direction. The waterproof baffles 12 are inclined along the bending direction of the bottom of the sewage discharge chassis 1. The waterproof baffles 12 and the first direction form an angle α, 45°≤α<90°. Since the bottom of the sewage discharge chassis 1 is arc-shaped, the material is easy to slide out on both sides of the sewage discharge chassis 1. The setting of the waterproof baffles 12 can guide the falling material into the sewage discharge chassis 1, and can also reduce the probability of the material in the sewage discharge chassis 1 falling out of the sewage discharge chassis 1 from both sides.
[0036] like Figure 4 In the illustrated embodiment, water guide plates 41 are provided on both sides of the conveyor belt 4. The water guide plates 41 are inclined, one side of the water guide plate 41 extends to the outside of the conveyor belt 4, and the other side of the water guide plate 41 extends to above the waterproof baffle 12 or above the sewage chassis 1. The water guide plates 41 are suitable for guiding the water on the conveyor belt 4 to the waterproof baffle 12 or the sewage chassis 1. The water guide plates 41 cooperate with each other to form a funnel-shaped structure that gradually shrinks toward the sewage chassis 1 below the conveyor belt 4, so as to guide and collect the materials falling from the conveyor belt 4 and the sewage flowing down.
[0037] In some embodiments, the projections of the waterproof baffle 12 and the water guide plate 41 in the vertical plane passing through the central axis of the conveyor belt 4 at least partially overlap, which can improve the material receiving effect and reduce the probability of the material falling out of the waterproof baffle 12.
[0038] In some embodiments, the projections of the waterproof baffle 12 and the water guide plate 41 in the horizontal plane at least partially overlap, which can improve the material connection effect and reduce the probability of the material falling out of the waterproof baffle 12.
[0039] In some embodiments, one end of the sewage hopper 2 away from the sewage outlet 11 is lower than the sewage outlet 11 , so that the water-containing material can flow out of the sewage hopper 2 more smoothly and quickly.
[0040] In some embodiments, sewage baffles 21 are provided on both sides of the sewage hopper 2. The sewage baffles 21 gradually approach the center line of the sewage hopper 2 in the direction away from the sewage chassis 1. The sewage baffles 21 are used to gather and guide the water-containing materials passing through the sewage hopper 2.
[0041] In some embodiments, the sewage discharge chassis 1 and the sewage discharge bucket 2 are bonded by a casting glue process, which can reduce weld scars and welds, solve the problem that weld scars and welds are easily corroded, and improve service life.
[0042] like Figures 3 to 5 As shown, the present application also provides a belt cleaning device, comprising a conveyor belt 4 and a sewage discharge mechanism of any of the above-mentioned embodiments.
[0043] like Figure 4 and 5 In the illustrated embodiment, a second flushing device 5 is provided below the conveyor belt 4. The second flushing device 5 includes a second flushing channel 51 and a second flushing head 52. The flushing direction of the second flushing head 52 is toward the bottom of the conveyor belt 4. The second flushing device 5 can be used to flush the structure and components at the conveyor belt 4, and the sewage flushed can be received and uniformly discharged by the sewage discharge mechanism below.
[0044] It can be understood that the sewage discharge mechanism and belt cleaning device of the present application can be applied to the field of coal mine transportation, can effectively deal with the collection and sewage discharge of the corrosive aqueous coal powder suspension generated during belt cleaning, and has high stability in use and a long service life.
