[0023] In order to solve the problem in the prior art that the service life of the chute is short and the coal washing quality is reduced, the present application provides a connecting device and a coal washing production line having the same.

[0024] like Figure 1 As shown, the communication device includes a communication structure 10 and a buffer structure 20. The communication structure 10 has a feed port 11, a discharge port 12, and a communication cavity 13. The feed port 11 is connected to the discharge port 12 through the communication cavity 13. At least a portion of the communication structure 10 is arranged in an inclined shape so that the material entering the communication cavity 13 through the feed port 11 moves toward the discharge port 12 under the action of gravity. The communication cavity 13 has a buffer section, and the bottom wall of the buffer section is provided with a receiving recess 131 for accommodating the material. The buffer structure 20 is arranged on the cavity wall of the communication cavity 13. The buffer structure 20 buffers the material by limiting the movement of the material.

[0025] Applying the technical solution of this embodiment, the communication device includes a communication structure 10 and a buffer structure 20. In the communication device, the communication structure 10 has a feed port 11, a discharge port 12, and a communication cavity 13. The feed port 11 is connected to the discharge port 12 through the communication cavity 13. At least part of the communication structure 10 is arranged in an inclined shape so that the material entering the communication cavity 13 through the feed port 11 moves toward the discharge port 12 under the action of gravity. The communication cavity 13 has a buffer section, and a receiving recess 131 for receiving the material is provided on the bottom wall of the buffer section. The buffer structure 20 is provided on the cavity wall of the communication cavity 13. The buffer structure 20 buffers the material by limiting the material during movement. In this way, as the material flows from the feed port 11 to the discharge port 12, the material will fall into the receiving recess 131, thereby slowing down the flow rate of the material and reducing the impact force of the material on the connecting device. When the receiving recess 131 is filled, the materials in the receiving recess 131 will rub against each other, thereby achieving material transportation while reducing the friction area between the material and the wall of the connecting cavity 13, greatly reducing the wear rate of the wall and extending the service life of the connecting device. At the same time, the buffer structure 20 can buffer the impact of the material, further reducing the flow rate of the material and reducing the impact force, while avoiding the impact and fragmentation of the material, thereby improving the processing quality of the material, thereby solving the problem of the short service life of the chute in the prior art and causing the coal washing quality to be reduced.

[0026] In this embodiment, the material is coal.

[0027] like Figure 1 As shown, there are multiple accommodating recesses 131, which are spaced apart along the direction of material movement. Thus, the multiple accommodating recesses 131 are arranged in the buffer section, ultimately forming a stepped structure. This further reduces the friction area between the material and the wall of the connecting cavity 13, while making the number of accommodating recesses 131 more flexible and diverse to accommodate different working conditions and usage requirements, and also improving the processing flexibility of the staff.

[0028] like Figure 1 As shown, there are multiple accommodating recesses 131, at least one of which is located opposite the feed port 11. In this way, the material flowing out of the feed port 11 at a relatively high speed can directly collide with the material accumulated in the accommodating recess 131 located opposite the feed port 11. Through the collision between the materials, the flow rate of the material is quickly reduced while extending the service life of the connecting device.

[0029] like Figure 1As shown, the connecting structure 10 includes a tubular connecting body 14 and a receiving structure 15. The tubular connecting body 14 has an inlet 11, an outlet 12, and a first mounting opening. The first mounting opening is located on the bottom wall of the inner bore of the tubular connecting body 14. The receiving structure 15 has a receiving recess 131, and the receiving structure 15 is removably mounted to the first mounting opening via the first mounting structure. This allows for a removable connection between the receiving structure 15 and the tubular connecting body 14, making it easier for workers to replace the receiving structure 15 and further extending the service life of the chute.

[0030] In this embodiment, the first mounting structure is a flange bolt structure, and the containing structure 15 is detachably mounted at the first mounting port through the flange bolt structure, thereby ensuring that the containing structure 15 is firmly and reliably mounted and prevents it from loosening or falling off due to vibration or impact, thereby realizing the detachable setting of the containing structure 15.

[0031] In this embodiment, the receiving structure 15 is in the shape of a triangular prism.

[0032] Specifically, the containing structure 15 is a "bucket-shaped" container formed by removing a prism surface of the containing structure 15 .

[0033] like Figure 1 As shown, the tubular connecting body 14 includes a first sub-tubular structure 141, a second sub-tubular structure 142, and a third sub-tubular structure 143 that are interconnected. The second sub-tubular structure 142 is located between the first sub-tubular structure 141 and the third sub-tubular structure 143. The first sub-tubular structure 141 has a discharge port 12, and the third sub-tubular structure 143 has a discharge port 12. The second sub-tubular structure 142 is arranged in an inclined shape to form a buffer section, and the first mounting port is arranged on the bottom wall of the inner hole of the second sub-tubular structure 142. In this way, the first sub-tubular structure 141, the second sub-tubular structure 142, and the third sub-tubular structure 143 included in the tubular connecting body 14 are connected one by one to form a tight material flow channel to prevent material leakage. At the same time, the above arrangement also makes the structure of the tubular connecting body 14 simpler, easier to process and implement, thereby reducing the processing cost of the tubular connecting body 14.

[0034] Specifically, the first sub-tubular structure 141 is mounted vertically and fixedly to facilitate the flow of materials from the feed port 11. The second sub-tubular structure 142 is mounted at an appropriate angle to ensure a moderate falling speed of the materials under the action of gravity. The third sub-tubular structure 143 is mounted vertically and fixedly to facilitate the flow of materials from the discharge port 12 and prevent material accumulation.

[0035] like Figure 1As shown, the buffer structure 20 is disposed on the inner wall of the third sub-tubular structure 143. Along the extension direction of the second sub-tubular structure 142, the projection of the second sub-tubular structure 142 onto the inner wall of the third sub-tubular structure 143 forms the impact zone, and the buffer structure 20 is located within this zone. This buffer structure 20 disperses the impact force of the material on the impact zone of the third sub-tubular structure 143, thereby reducing wear on the inner wall of the third sub-tubular structure 143 and preventing wear in the impact zone. Furthermore, by buffering the impact force of the material, material fragmentation can be avoided, thereby improving the processing quality of the material.

[0036] In this embodiment, a second mounting opening is provided on the inner wall of the third sub-tubular structure 143, located within the impact zone. The buffer structure 20 includes a cover-like body that is removably mounted to the second mounting opening via a second connecting structure. This allows the cover-like body to be removably mounted to the second mounting opening via the second connecting structure, making it easier for personnel to remove the cover-like body. This allows personnel to replace the cover-like body if damaged, extending the service life of the communication device.

[0037] In this embodiment, the buffer structure 20 further includes a first buffer member disposed within the cover-shaped body. The first buffer member is used to limit and stop the material. At least a portion of the first buffer member is made of a flexible material. This allows the first buffer member to absorb the material's kinetic energy, reduce its flow rate, and reduce noise caused by impact.

[0038] In this embodiment, the buffer structure 20 adopts a box-type detachable structure (hood-shaped body), and scraper steel sheets are welded inside. Regular replacement of the scraper steel sheets can also extend the service life of the entire buffer structure 20.

[0039] Specifically, the scraper steel sheet is made of manganese steel to ensure high wear resistance of the scraper steel sheet.

[0040] Optionally, the containment structure 15 has a discharge hole connected to the containment recess 131, and the buffer structure 20 and containment structure 15 further include: a blocking member, reversibly disposed on the containment structure 15, having a blocking position and a relief position. When the blocking member is in the blocking position, the blocking member blocks the discharge hole; when the blocking member is in the relief position, the blocking member avoids at least a portion of the discharge hole; and / or a second buffer member, disposed on the bottom wall of the containment recess 131, for limiting and stopping material falling into the containment recess 131, at least a portion of the second buffer member being made of an elastic material. Thus, when the blocking member is reversibly disposed in the blocking position, the discharge hole is blocked, and material is accumulated within the containment recess 131, thereby reducing material flow and ensuring normal operation of the communication device. When the blocking member is reversibly disposed in the relief position, the discharge hole is opened, allowing material to flow out of the containment recess 131, thereby preventing blockage of the communication device. Furthermore, the second buffer member is made of an elastic material, which can reduce noise when it collides with material, thereby improving the working environment for employees.

[0041] This embodiment also provides a coal washing production line (not shown), which includes multiple coal washing equipment and a connecting device. The connecting device is used to connect two adjacent coal washing equipment, and the connecting device is the above-mentioned connecting device.

[0042] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0043] The connecting device includes a connecting structure and a buffer structure. The connecting structure has a feed port, a discharge port and a connecting cavity. The feed port is connected to the discharge port through the connecting cavity. At least part of the connecting structure is arranged in an inclined shape so that the material entering the connecting cavity through the feed port moves toward the discharge port under the action of gravity. The connecting cavity has a buffer section, and a receiving recess for receiving the material is provided on the bottom wall of the buffer section; the buffer structure is provided on the cavity wall of the connecting cavity, and the buffer structure buffers the material by limiting and stopping the material during the movement. In this way, in the process of the material flowing from the feed port to the discharge port, the material will fall into the receiving recess to slow down the flow speed of the material and reduce the impact force of the material on the connecting device. When the receiving recess is filled, the material in the receiving recess will rub against each other, thereby reducing the friction area between the material and the cavity wall of the connecting cavity while realizing material transportation, greatly reducing the wear rate of the cavity wall and extending the service life of the connecting device. At the same time, the buffer structure can cushion the impact of the material, further reducing the flow rate of the material and the magnitude of the impact force, while avoiding the impact and fragmentation of the material, thereby improving the processing quality of the material, and further solving the problem of the short service life of the chute in the prior art and the reduction in the quality of coal washing.
