[0002] In the production process of fine coal, vertical dryer plays a vital role. Its main function is to dry the fine coal to meet the requirements of subsequent processing and use. However, traditional fine coal vertical dryer has many significant problems in the unloading link. Among them, the unloading drive system is often more complicated, requiring multiple power sources and complex transmission structures to realize the opening and closing of the unloading plate, which not only leads to high equipment manufacturing costs, but also increases energy consumption and equipment operation instability. Too many power components and complex transmission links increase the system failure rate, and the maintenance difficulty and cost also increase accordingly, which seriously affects the continuity and economy of production. To this end, we propose a unloading device for fine coal vertical dryer. Utility Model Content

[0023] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0024] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] Please see the attached Figure 1 -Attached Figure 5The utility model discloses a discharge device of a fine coal vertical dryer, comprising a discharge pipe 1, a discharge assembly 2 being provided at the bottom of the discharge pipe 1, the discharge assembly 2 being openably and closably mounted on the bottom edge of the discharge pipe 1, the discharge assembly 2 comprising a bottom box 21, a limiting ring 22, a rotating ring 23, a baffle plate 24 and a transmission connecting rod 25, the top of the bottom box 21 being open, a through opening 211 being provided in the middle thereof, the limiting ring 22 being fixed to the top of the bottom plate of the bottom box 21, and the limiting ring 22 being located at the periphery of the through opening 211, the rotating ring 23 being rotatably mounted on the top of the bottom plate of the bottom box 21 with the center of the through opening 211 as a reference, and the rotating ring 23 being located at the periphery of the limiting ring 22;

[0026] The material baffle 24 is provided with three corners, namely corner one 241, corner two 242 and corner three 243. Corner one 241 is rotatably connected to pivot one 221 provided at the top of the limiting ring 22, and corner two 242 is transmission-connected to the rotating ring 23 through a transmission link 25. One end of the transmission link 25 is rotatably connected to pivot two 244 provided at the top of corner two 242, and the other end of the transmission link 25 is rotatably connected to pivot three 231 provided at the top of the rotating ring 23, and a push block 232 is provided on the outside of the rotating ring 23, and the push block 232 slides in fit with the slot 212 provided on the outside of the bottom box 21.

[0027] In the first embodiment, there are five baffle plates 24 and five transmission connecting rods 25, and the two correspond one to one. The corners 241 of each of the five baffle plates 24 are respectively rotatably connected to the five pivot shafts 221 evenly spaced at the top of the limiting ring 22. The side wall between the corner 1 241 and the corner 3 243 of one baffle plate 24 coincides with the side wall between the corner 242 and the corner 3 243 of the adjacent baffle plate 24.

[0028] Specifically, the corners 241 of each of the five baffle plates 24 are rotatably connected to the five pivot shafts 221 evenly spaced at the top of the limiting ring 22, thereby constructing a stable rotation connection structure, so that each baffle plate 24 can flexibly adjust the angle within a specific rotation range, wherein the side wall between the corner 1 241 and the corner 3 243 of one baffle plate 24 coincides with the side wall between the corner 2 242 and the corner 3 243 of the adjacent baffle plate 24. This structural design helps to form a good sealing effect when the baffle plate 24 is closed, effectively preventing material leakage.

[0029] In the second embodiment, the five transmission connecting rods 25 are respectively rotatably connected with the five second pivot shafts 244 evenly spaced at the top of the rotating ring 23. The top of the rotating ring 23 is evenly spaced with limit grooves 233 running through its bottom. The top of the bottom plate of the bottom box 21 is provided with a limit column 213 corresponding to the limit groove 233. A bracket 214 is welded to the side wall of the bottom box 21. The electric push rod 3 is installed on the bracket 214. The connecting block 301 provided at the output end of the electric push rod 3 is connected to the push block 232 on the outside of the rotating ring 23. The top edge of the bottom box 21 is connected to the mounting block 101 welded to the periphery of the bottom end of the discharge pipe 1 through a bolt pair 4. The top of the discharge pipe 1 is connected to the discharge port of the dryer.

[0030] Specifically, the five transmission links 25 are respectively rotatably connected to the five pivot shafts 244 evenly spaced at the top of the rotating ring 23, ensuring the uniformity and stability of the connection between the transmission links 25 and the rotating ring 23, so that when the rotating ring 23 rotates, the transmission links 25 can accurately and evenly drive each baffle plate 24 to perform synchronous opening and closing actions, thereby achieving precise control of the unloading amount. Through the cooperation of the limit groove 233 and the limit column 213, the rotation range of the rotating ring 23 can be further limited to prevent it from excessive deviation or shaking during the rotation process, thereby improving the operating stability of the entire unloading assembly 2. Through the telescopic movement of the electric push rod 3, the rotating ring 23 can be accurately driven to rotate, and then the baffle plate 24 can be driven to open and close with the help of the transmission link 25, providing a strong guarantee for the automatic control of the unloading device.

[0031] Working principle:

[0032] First, in the initial state of the device, the electric push rod 3 is in a retracted state. At this time, the baffle plate 24 is in a closed position, and the material is blocked in the discharge pipe 1 and cannot fall. When unloading is required, the electric push rod 3 is started, and its output end extends to push the rotating ring 23 to rotate along the top of the bottom plate of the bottom box 21. Since the transmission connecting rod 25 is respectively connected to the second corner 242 of the baffle plate 24 and the rotating ring 23, the rotation of the rotating ring 23 will drive the transmission connecting rod 25 to move, and then the baffle plate 24 rotates around the pivot 1 221 on the limit ring 22, realizing the opening action of the baffle plate 24, and the material can fall through the opening 211 of the bottom box 21;

[0033] Secondly, during the rotation of the rotating ring 23, the push block 232 on the outside thereof slides along the notch 212 on the outside of the bottom box 21. At the same time, the limiting groove 233 on the top of the rotating ring 23 cooperates with the limiting post 213 on the top of the bottom plate of the bottom box 21 to ensure that the rotating ring 23 rotates smoothly and within a predetermined range.

[0034] Finally, by controlling the telescopic stroke of the electric push rod 3, the opening and closing degree of the baffle plate 24 can be accurately adjusted, thereby achieving precise control of the discharge amount. At this point, the entire workflow is completed.

[0035] The above-mentioned front, back, left, right, up and down are all based on the Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.

[0036] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments.

[0038] For those skilled in the art, it is possible to make various changes, modifications, substitutions and variations to these embodiments without departing from the principles and spirit of the present invention, and they still fall within the scope of protection of the present invention.
