Abstract
Description
Technical Field
[0001] This utility model relates to the field of cement fly ash, specifically to a flushing pipe at the liquid outlet. Background Technology
[0002] Centrifuges used for treating cement fly ash require flushing of the outlet end via a flushing pipe after use. Existing flushing pipes typically have water inlet at one end and outlet at the side wall. This presents the following problems: 1. The main water supply loop is long, resulting in a long flow time of the flushing water within the pipe; 2. The central axis of the inlet and outlet forms a 90° angle, leading to high flow resistance of the flushing water within the pipe. Utility Model Content
[0003] The purpose of this utility model is to provide a flushing pipe assembly at the liquid outlet end to solve at least one of the above-mentioned technical problems.
[0004] A flushing pipe assembly at the liquid outlet includes a straight pipe with at least four outlets on its side wall. The straight pipe is characterized in that it also has one and only one inlet on its side wall, and at least two outlets are provided on each side of the inlet.
[0005] The central axis of the inlet forms a 75° angle with the central axis of the outlet.
[0006] Yes, the outlets can be arranged at equal intervals. Alternatively, the distance between two adjacent outlets can gradually increase from left to right.
[0007] Preferably, the water inlet is provided with a first connecting pipe, one end of which is welded to the straight pipe, and the other end of the first connecting pipe is provided with a threaded joint on its outer side wall.
[0008] Preferably, the outlet is provided with a second connecting pipe, the upper end of which is welded to a straight pipe, and the lower outer wall of the second connecting pipe is provided with a first annular protrusion protruding outward, the side wall of which is provided with an external thread; the lower inner wall of the first connecting pipe is provided with a second annular protrusion protruding inward, and a third connecting pipe is inserted into the second annular protrusion; the second connecting pipe is fitted with a cylindrical connecting sleeve, the upper inner wall of which is provided with a third annular protrusion protruding inward, the third annular protrusion being provided with an internal thread matching the external thread, and the lower inner wall of the connecting sleeve is provided with a fourth annular protrusion protruding inward, the fourth annular protrusion being welded to the third connecting pipe.
[0009] 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.
[0010] Beneficial effects: 1. The inlet of this invention is located between the inlet and outlet, which effectively reduces the length of the total water supply circuit, thereby effectively reducing the flow time of the flushing water in the flushing pipe. 2. This invention changes the existing 90° angle between the inlet and outlet to a 75° angle, which effectively reduces the flow resistance of the flushing water in the flushing pipe. 3. This invention optimizes the structure of the outlet, which can effectively increase the outlet water pressure. Attached Figure Description

[0014] 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.
[0015] Reference Figure 1 , Figure 2 and Figure 3 The flushing pipe assembly includes a straight pipe 1 with outlets on its side wall. There are at least four outlets. The four outlets can be arranged at equal intervals, or the distance between two adjacent outlets can gradually increase from left to right. Gradually increasing distance is preferred. This allows for different water pressures to be obtained by utilizing the varying distances from the outlets to the inlets, or for flushing different positions at the flushing end.
[0016] A water inlet 2 may also be provided on the side wall of the straight pipe 1. There is only one water inlet 2, preferably located in the middle of the straight pipe 1. Preferably, at least two water outlets are provided on each side of the water inlet 2. This can effectively reduce the length of the total water supply circuit, thereby effectively reducing the flow time of the flushing water in the flushing pipe.
[0017] The central axis of the inlet 2 forms a 75° angle with the central axis of the outlet. This invention changes the existing 90° angle to a 75° angle, which can effectively reduce the flow resistance of flushing water in the flushing pipe.
[0018] The inlet 2 is provided with a first connecting pipe 3. One end of the first connecting pipe 3 is welded with a straight pipe 1, and the other end of the first connecting pipe is provided with a threaded joint on the outer wall, so as to connect to the outside through the threaded joint.
[0019] A second connecting pipe 4 is provided at the water outlet. A straight pipe 1 is welded to the upper end of the second connecting pipe 4. A first annular protrusion protrudes outwards on the outer wall of the lower end of the second connecting pipe 4, and external threads are provided on the side wall of the first annular protrusion. A second annular protrusion protrudes inwards on the inner wall of the lower end of the first connecting pipe, and a third connecting pipe 7 is inserted into the second annular protrusion. An opening is provided at the lower end of the third connecting pipe 7 for connecting a spherical spray head, which makes the water flow more even. A cylindrical connecting sleeve 5 is fitted over the second connecting pipe 4. A third annular protrusion protrudes inwards on the inner wall of the upper end of the connecting sleeve 5, and internal threads matching the external threads are provided on the third annular protrusion. The connecting sleeve 5 connects to the external threads using the internal threads. 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. The lower part forms a stepped structure, which can be used to limit the third connecting pipe 7 by abutting against the stepped structure at its top end, while also reducing the sealing difficulty between the third connecting pipe 7 and the first connecting pipe. A fourth annular protrusion protrudes inward on the inner sidewall of the lower end of the connecting cylinder 5, allowing the third connecting pipe 7 to be welded. This restricts the position of the second connecting pipe 4. A strip-shaped groove is provided on the sidewall of the connecting cylinder 5, with the extension direction of the groove parallel to the central axis of the connecting cylinder 5. This allows for the use of a tool to engage the groove and complete the threaded connection. Preferably, the inner diameter of the third connecting pipe 7 gradually decreases from left to right to increase the outlet water pressure.
[0020] Both ends of the straight pipe 1 are equipped with threaded joints 6 for easy external connection. The inner wall of the straight pipe 1 may have spiral grooves with inward openings, thereby guiding the direction of water flow. The grooves are arranged symmetrically on both sides with the inlet 2 as the center of symmetry.
[0021] 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.
