Description

Technical Field

[0001] This utility model relates to the field of cement fly ash, specifically to a flushing pipe at the slag discharge end. Background Technology

[0002] Centrifuges used for treating cement fly ash require flushing of the discharge end via a flushing pipe after use to prevent material adhesion and blockage. In practice, it has been found that the area behind the discharge end can be flushed by the water flowing down from the front. However, existing flushing pipes at the discharge end typically have liquid outlets spaced evenly, meaning the water usage at the rear is not reduced by the water flowing down from the front, resulting in a large volume of flushing water. Utility Model Content

[0003] The purpose of this utility model is to provide a slag discharge end flushing pipe assembly to solve the above-mentioned technical problems.

[0004] A slag discharge end flushing pipe assembly includes a straight pipe, the right end of which is connected to a curved pipe, and the straight pipe has a liquid outlet. The liquid outlet is characterized in that there are at least three liquid outlets, and the distance between two adjacent liquid outlets is smaller as they are closer to the curved pipe.

[0005] Preferably, the liquid outlet is provided with a connecting assembly, which includes a first assembly, a second assembly, and a third assembly;

[0006] The first component includes a first connecting pipe, the upper end of which is welded to the straight pipe; the lower outer side wall of the first connecting pipe is provided with a first annular protrusion protruding outward, and the side wall of the first annular protrusion is provided with external threads; the lower inner side wall of the first connecting pipe is provided with a second annular protrusion protruding inward.

[0007] The third component is a tubular second connecting tube, which is inserted into the second annular protrusion.

[0008] The second component includes a cylindrical connecting cylinder, the upper inner wall of which is provided with an inwardly protruding third annular protrusion, and the third annular protrusion is provided with an internal thread that matches the external thread.

[0009] The lower inner wall of the connecting cylinder is provided with a fourth annular protrusion that protrudes inward, and the second connecting pipe is welded to the fourth annular protrusion.

[0010] Preferably, the inner diameter of the second annular protrusion gradually decreases from top to bottom, then remains constant, then suddenly increases, and then remains constant again.

[0011] Preferably, the side wall of the connecting cylinder is provided with a strip-shaped groove, and the extending direction of the strip-shaped groove is parallel to the central axis of the connecting cylinder.

[0012] Preferably, the inner diameter of the second connecting pipe is larger as it gets closer to the bend in the pipe.

[0013] Beneficial effects: 1. This utility model changes the equal spacing of the liquid outlets to a higher density closer to the bend in the pipe, thereby increasing the number of liquid outlets in front of the slag discharge end and reducing the number of liquid outlets behind the slag discharge end. The water flowing down from the front of the slag discharge end assists in rinsing the area behind it, thus reducing the amount of water used for rinsing. 2. The connecting components of this utility model are easy to install and replace. Whether the liquid outlet is connected to the connecting components and whether the connecting components are connected to the spherical spray head can be selected as needed. 3. This utility model limits the inner diameter of the second connecting pipe to be larger closer to the bend in the pipe, thereby increasing the pressure at the rear of the slag discharge end and ensuring the rinsing effect.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0018] Reference Figure 1 , Figure 2 and Figure 3 The slag discharge end flushing pipe assembly includes a straight pipe 2, and a bent pipe 1 is connected to the right end of the straight pipe 2. The straight pipe 2 has liquid outlets, at least three of which are provided, and the distance between two adjacent liquid outlets is smaller as they are closer to the bent pipe 1.

[0019] A connecting assembly is provided at the liquid outlet. The connecting assembly includes a first assembly 4, a second assembly 5, and a third assembly 6. The first assembly 4 includes a first connecting pipe, the upper end of which is welded to a straight pipe 2. The lower outer wall of the first connecting pipe has an outwardly protruding first annular protrusion, and the side wall of the first annular protrusion has external threads. The lower inner wall of the first connecting pipe has an inwardly protruding second annular protrusion. The third assembly 6 is a tubular second connecting pipe, which is inserted into the second annular protrusion. The second assembly 5 includes a cylindrical connecting cylinder, the upper inner wall of which has an inwardly protruding third annular protrusion, and the third annular protrusion has internal threads that match the external threads. The second assembly 5 uses internal threads to connect to external threads. The second connecting pipe can be directly inserted into the slag outlet to clean the slag outlet. Alternatively, the lower end of the second connecting pipe has an opening 7 for connecting a spherical spray head, which makes the water output more uniform.

[0020] Preferably, the inner diameter of the second annular protrusion gradually decreases from top to bottom, then remains constant, then suddenly increases, and then remains constant again, thus forming a trumpet-shaped structure at the top, which is beneficial for increasing water pressure, and a stepped structure at the bottom. This allows the second connecting pipe to be positioned by abutting against the stepped structure at its top end, while also reducing the sealing difficulty between the second connecting pipe and the first component 4. A fourth annular protrusion protrudes inward on the inner sidewall of the lower end of the connecting cylinder, allowing the second connecting pipe to be welded to it. Alternatively, the second connecting pipe may have an outward-protruding annular baffle, the outer diameter of which is larger than the inner diameter of the fourth annular protrusion. The baffle presses against the fourth annular protrusion from above, thus restricting the position of the second connecting pipe. A strip-shaped groove 3 is provided on the sidewall of the connecting cylinder, extending parallel to the central axis of the connecting cylinder. This allows a tool to be engaged using the groove 3, enabling the threaded connection between the second component 5 and the first component 4. Alternatively, the outer contour of the connecting cylinder's cross-section may be an equilateral hexagonal shape. This makes the connecting cylinder nut-shaped, allowing the threaded connection between the second component 5 and the first component 4 to be completed using existing tools.

[0021] The straight pipe 2 and the bent pipe 1 are preferably connected by welding to ensure a tight seal. The end of the bent pipe 1 furthest from the straight pipe 2 is preferably equipped with a threaded joint. The end of the straight pipe 2 furthest from the bent pipe 1 is preferably equipped with a threaded joint 8. This allows for more convenient external connections using the threaded joints.

[0022] The inner diameter of the second connecting pipe is preferably larger as it approaches the bend in the pipe 1. This increases the water flow rate in front of the slag discharge end, reduces the water flow rate behind the slag discharge end, and increases the water pressure behind the slag discharge end. Alternatively, the inner diameter of the second connecting pipe can gradually decrease from top to bottom to increase the outlet water pressure.

[0023] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
