DETAILED DESCRIPTION
[0022] The utility model is further described below in combination with the drawings.
[0023] The directions involved in the specification are based on the directions of the cyclone discharge port buffering device when it is normally working, and are not limited to the directions when it is stored and transported, and only represent relative positional relationships, not absolute positional relationships.
[0024] Embodiment one:
[0025] For example, Figure 1 , Figure 2 and Figure 3As shown in the figure, a cyclone discharge port buffer device includes a square shell 1 fixed on the discharge port 9 of the cyclone 8, the square shell 1 is arranged in the material collecting box 2, the left side of the square shell 1 is provided with a communication hole 10 communicating with the discharge port 9, and the bottom end of the square shell 1 is open and the diameter of the bottom end of the square shell 1 gradually shrinks downward.
[0026] The square shell 1 is fixed on the discharge port 9, and the coal discharged from the discharge port 9 first enters the square shell 1, and then enters the material collecting box 2 after being blocked and buffered by the square shell 1, thereby avoiding the coal directly impacting the material collecting box 2, reducing the pressure of the material collecting box 2, and greatly reducing the risk of damage of the material collecting box 2 caused by impact. The bottom end of the square shell 1 is open and the diameter of the bottom end of the square shell 1 gradually shrinks downward, so that the bottom end of the square shell 1 is inwardly inclined, so that the coal sliding down the inner wall of the shell passes through the bottom end of the square shell 1 and slides down the inclined bottom end, and the coal is guided and buffered.
[0027] As a preferred case of the embodiment, the square shell 1 is forwardly inclined. The forward inclination of the square shell 1 makes the back side plate 15 of the square shell 1 forwardly inclined, and the coal impacting the right side plate 13 of the square shell 1 falls onto the back side plate 15, which can further buffer the coal and further reduce the impact force, thereby avoiding damage to the lower tank plate of the material collecting box 2.
[0028] As a preferred case of the embodiment, the square shell 1 is made of the upper side plate 11, the left side plate 12, the right side plate 13, the front side plate 14 and the back side plate 15, and the bottom ends of the left side plate 12, the right side plate 13, the front side plate 14 and the back side plate 15 are inwardly bent. The square shell 1 adopts the above structure, which can increase the strength of the square shell 1 and improve the service life of the square shell 1.
[0029] The upper side plate 11, the left side plate 12, the right side plate 13, the front side plate 14 and the back side plate 15 are made of wear-resistant plates made of high-hardness and excellent wear-resistant alloy, and the side plates are welded to form the square shell 1.
[0030] Embodiment two:
[0031] As Figure 1 , Figure 2 and Figure 4As shown, as a further improvement to Embodiment 1, a first buffer plate 16, a second buffer plate 17, and a third buffer plate 18 are sequentially fixed to the right side plate 13 from top to bottom at an inclined arrangement. The angle between the first buffer plate 16 and the right side plate 13 is smaller than the angle between the second buffer plate 17 and the right side plate 13, and the angle between the second buffer plate 17 and the right side plate 13 is smaller than the angle between the third buffer plate 18 and the right side plate 13. With this structure, when coal falls onto the first buffer plate 16, its direction changes, and it moves downwards along the first buffer plate 16 to the second buffer plate 17. The second buffer plate 17 then changes the direction of the coal, causing it to move downwards onto the third buffer plate 18 and continue moving downwards along it. After being buffered by the first buffer plate 16, the second buffer plate 17, and the third buffer plate 18, the coal falls into the collection box 2, further reducing the discharge pressure and preventing damage to the collection box 2. The angle between the three buffer plates and the right side plate 13 gradually increases, which allows the impact force of the coal to be gradually reduced.
[0032] In a preferred embodiment, the lower end of the first buffer plate 16 extends onto and is fixedly connected to the second buffer plate 17, and the lower end of the second buffer plate 17 extends onto and is fixedly connected to the third buffer plate 18. This structure allows the three buffer plates to be connected and reinforce each other, preventing them from detaching or being damaged.
[0033] The first buffer plate 16, the second buffer plate 17 and the third buffer plate 18 are all welded to the right side plate 13. The first buffer plate 16 is welded to the second buffer plate 17 and the second buffer plate 17 is welded to the third buffer plate 18.
[0034] In a preferred embodiment, a reinforcing plate 19 is fixedly connected to the lower end of the third buffer plate 18, and the other end of the reinforcing plate 19 is fixedly connected to the right side plate 13. Specifically, both ends of the reinforcing plate 19 are welded to the right side plate 13 and the third buffer plate 18, respectively. The reinforcing plate 19 strengthens the third buffer plate 18 and prevents it from falling off.
[0035] In a preferred embodiment, a fourth buffer plate 3 is fixedly connected to the left side plate 12 at an angle, and the fourth buffer plate 3 is located below the connecting hole 10. Specifically, the fourth buffer plate 3 is welded to the left side plate 12, and the fourth buffer plate 3 can buffer the coal falling along the left side plate 12.
[0036] Furthermore, a connecting plate is welded to the lower end of the fourth buffer plate 3, and the other end of the connecting plate is welded to the left side plate 12.
[0037] Example 3:
[0038] likeFigure 1 and Figure 5 As shown, as a further improvement to Embodiment 1, the lower parts of the right side plate 13, front side plate 14, and rear side plate 15 are all fixedly connected with first reinforcing ribs 4. The upper ends of the three first reinforcing ribs 4 are connected by connecting blocks 5 surrounding the square shell 1. The end of the connecting block 5 is fixedly connected to the discharge port 9. The lower part of the left side plate 12 is fixedly connected with second reinforcing ribs 6, and the upper end of the second reinforcing ribs 6 is fixedly connected to the discharge port 9. Specifically, the first reinforcing ribs 4 are welded to each side plate, the connecting block 5 is welded to the upper end of the first reinforcing ribs 4, the end of the connecting block 5 is welded to the discharge port 9, and the second reinforcing ribs 6 are welded to the left side plate 12 and the discharge port 9. The provision of the first reinforcing ribs 4 and the second reinforcing ribs 6 can strengthen the lower part of the square shell 1 and prevent deformation of the bottom of the square shell 1.
[0039] Furthermore, a reinforcing block 7 is welded to the bottom of adjacent reinforcing ribs.
[0040] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
