Description

Technical Field

[0001] This utility model belongs to the field of pneumatic ash conveying technology, specifically relating to an ash conveying elbow. Background Technology

[0002] Thermal power generation utilizes the heat energy generated during the combustion of combustible materials, converting it into electrical energy through a power generation device. In thermal power generation technology, a large amount of dust is produced during fuel combustion. Existing technologies employ pneumatic ash conveying, which uses gas to carry dust and smoke through pipes to designated equipment. However, the pipeline connection requires ash conveying elbows to connect two cross-shaped pipes. Since pneumatic ash conveying uses gas with a certain impact force to transport dust, the cross-shaped intersection of the ash conveying elbows experiences significant wear. Existing ash conveying elbows cannot replace components at the worn locations, resulting in a short service life for the ash conveying elbows. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides an ash conveying elbow. The adjusting ring of the ash conveying elbow can be rotated to adjust the position so that different adjusting plates reach the intersection and face the strong impact of the airflow.

[0004] A conveying elbow includes a pipe body with an adjusting ring rotatably disposed inside the pipe body. An adjusting plate is integrally disposed on the inner side wall of the adjusting ring. An adjusting mechanism is disposed on one side of the pipe body. The adjusting mechanism includes an air inlet pipe, an outlet pipe, and a rotating pipe. The rotating pipe is rotatably disposed on one side of the pipe body. An outlet pipe is slidably disposed on one side of the rotating pipe. A bidirectional groove is formed on one side of the rotating pipe. An adjusting frame is attached to the surface of the bidirectional groove. The adjusting frame is slidably disposed on one side of the pipe body. A holding spring is disposed between the adjusting frame and the pipe body. The outlet pipe is attached to one side of the adjusting frame.

[0005] The beneficial effects of the above technical solution are as follows:

[0006] The adjustable ring in this design can be rotated to adjust the position of different adjustable plates to reach the intersection. Facing the strong impact of the airflow, the adjustable ring can be fixed or not fixed, which reduces the impact of the airflow at the intersection. Through the bidirectional rotation adjustment of the rotating tube, the position of the adjustable ring can be fixed or rotated. A contact rod is provided on one side of the rotating tube to fix the adjustable ring when it is released. A ventilator connected to the external interface can clear the inside of the tube, allowing gas to be ejected from the nozzle. As the adjustable ring rotates, the position of the nozzle is adjusted.

[0013] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 5 The embodiments are described in detail below.

[0014] This embodiment provides an ash conveying elbow, as shown in the attached figure. Figures 1-5 As shown, the instruction manual is attached. Figure 1 This is a cross-sectional view of the solution; see the attached instruction manual. Figure 2 Included with instruction manual Figure 1 A 3D version, instruction manual included. Figure 3 Cut along the top of intake pipe 4. (See instruction manual attached.) Figure 4 Referenced from the instruction manual Figure 3 This particular location will be shown separately; the instruction manual is attached. Figure 5 The corresponding instruction manual is attached. Figure 4 This is a three-dimensional version, only concealing pipe body 1. The following is a description of this design. Pipe body 1 has two connecting flanges on both sides, responsible for connecting the perpendicular intersections of the ash conveying pipes. Because the ash conveying pipes have strong airflow, an adjusting ring 2 is installed in the middle of pipe body 1. The adjusting ring 2 is rotatably positioned in the middle of pipe body 1. When the airflow flows from left to right, the most easily worn area is at the upward-sloping part of the adjusting ring 2 (refer to the attached instruction manual). Figure 1), so in the adjustment ring 2 of the adjustment ring 2 of the present scheme has a plurality of array of adjustment plate 3, adjustment plate 3 is spiral downward shape, due to the pipeline inside the gas, can make the adjustment plate 3 impact of the air flow, air flow to a certain buffer, and impact adjustment plate 3 can adjust the position of the adjustment ring 2, make the adjustment ring 2 rotation, so as to fix in the process of rotation of the adjustment ring 2, so that different adjustment plate 3 to oblique up, to deal with the impact of air flow, in order to make the present scheme can control the regular switching of different adjustment plate 3 rotation to oblique up, in the pipe 1 side is provided with a rotatable air inlet pipe 4, air inlet pipe 4 side has a gear, gear meshing on the tooth ring 22, tooth ring 22 is fixedly arranged on the lower surface of the adjustment ring 2, so that the air inlet pipe 4 rotation can control the rotation of the adjustment ring 2, because the present scheme also needs to be fixed in the position of the adjustment ring 2 when not adjusting, so the present scheme is designed to rotate the rotatable rotating pipe 6, rotating pipe 6 has two functions, first, can make the adjustment frame 8 move towards the direction of the adjustment ring 2, second, the adjustment frame 8 away from the air inlet pipe 4, the outer surface of the rotating pipe 6 is provided with a bidirectional groove 7, the bidirectional groove 7 is two annular grooves, the middle part has a inclined groove connecting the two annular grooves, such as the description of the accompanying drawings Figure 5 Rotating pipe 6 counterclockwise rotation, will make the adjustment frame 8 under the action of bidirectional groove 7 move towards the direction of the adjustment ring 2 (because the adjustment frame 8 along the pipe 1 inside the limit sliding), rotating pipe 6 clockwise rotation will make the adjustment frame 8 away from the adjustment ring 2, and continue to rotate in one direction will make the adjustment frame 8 maintain in the separation from the adjustment ring 2 or close to the adjustment ring 2, in the side of the adjustment frame 8 has a maintain spring 9, this maintain spring 9 in the description of the accompanying drawings Figure 5When the spring is at its original length, the retaining spring 9 allows the cylinder on one side of the adjusting frame 8 to switch positions between the two annular grooves. This is the bidirectional rotation of the rotating tube 6. The bidirectional rotation controls the adjusting frame 8 to move laterally away from or towards the adjusting ring 2. When the adjusting frame 8 approaches the adjusting ring 2, it controls the extension tube 5 on one side of the rotating tube 6 to insert into the air intake pipe 4 (because the extension tube 5 and the rotating tube 6 can slide relative to each other but cannot rotate relative to each other, and the middle of the extension tube 5 overlaps one side of the adjusting frame 8, so the extension tube 5 will also move when the adjusting frame 8 moves). A driving block 12 is slidably provided on the side of the extension tube 5, and a driving block 12 is provided on one side of the driving block 12. A return spring 13 is provided. Because one side of the driving block 12 is inclined, even if it touches the inner block 14, it will not affect the scheme to restart the rotation of the intake pipe 4. Since the movement trajectory of the extension pipe 5 is a rotational entry, the driving block 12 can be rotated back to the edge of the inner block 14 even if it is squeezed by the inner block 14. This allows the rotating pipe 6 to continue rotating and drive the intake pipe 4 to rotate through the inspection pipe, achieving the effect of rotating the rotating pipe 6 in one direction to control the rotation of the adjusting ring 2. When the adjusting bracket 8 moves away from the adjusting ring 2, the fixing block 15 will be inserted between two adjacent outer blocks 16 (there are many outer blocks 16, not all of which are included in the instruction manual). Figure 5 In that way, similar to the number of contact grooves, the fixing block 15 can lock the outer block 16, so that the intake pipe 4 no longer rotates, that is, the position of the adjusting ring 2 is fixed. One side of the fixing block 15 has a fixing spring support, which also increases the fault tolerance of the fixing block 15.

[0015] The contact rod is slidably arranged on one side of the rotating pipe 6, and the two are provided with a compression spring 18, which is always in a compressed state, so that the release block is automatically inserted into the release slot 19 without external force, so that the contact rod cannot rotate, and the contact rod and the rotating pipe 6 can only slide, so that the rotating pipe 6 cannot rotate, that is, when the rotating pipe 6 is controlled to rotate, the contact rod is first squeezed by hand, and then the rotating pipe 6 is rotated, and the contact rod is not loosened, so that the rotating pipe 6 stops rotating, and the position of the adjusting frame 8 is fixed. The adjusting ring 2 of the present scheme can have two modes, one of which is not fixed, and the adjusting ring 2 can rotate under the action of wind, and the other is that the adjusting ring 2 is fixed, so that the inclined adjusting plate 3 buffers the wind force, and the present scheme has an external interface 21, which can be externally connected to a fan. The fan blows air into the inside of the pipe body 1, the air reaches the air inlet 10 of the air inlet pipe 4 (the air inlet pipe 4 and the pipe body 1 are sealed and rotated, and have a sealing ring and a bearing to make the air inlet pipe 4 rotate), and then is discharged from the air outlet 11 (the adjusting ring 2 and the pipe body 1 also have a rotary seal), and finally is sprayed through the spray outlet 20. Since the adjusting ring 2 can rotate, the spray outlet 20 can also rotate to adjust the position. The spray outlet 20 can play a certain role when it is blocked. The inside of the pipe body 1 is rotatably provided with the adjusting ring 2, the inner side wall of the adjusting ring 2 is integrally provided with the adjusting plate 3, one side of the pipe body 1 is provided with an adjusting mechanism, the adjusting mechanism comprises an air inlet pipe 4, an extension pipe 5 and a rotating pipe 6, the rotating pipe 6 is rotatably arranged on one side of the pipe body 1, the extension pipe 5 is slidably arranged on one side of the rotating pipe 6, and the rotating pipe 6 is provided with a double-sided slot 7 on one side. The surface of the double-sided slot 7 is lapped with the adjusting frame 8, the adjusting frame 8 is slidably arranged on one side of the pipe body 1, and a maintaining spring 9 is arranged between the adjusting frame 8 and the pipe body 1. One side of the adjusting frame 8 is lapped with the extension pipe 5, one side of the air inlet pipe 4 is provided with an air inlet 10, the other side of the air inlet pipe 4 is provided with an air outlet 11, both sides of the extension pipe 5 are slidably provided with a driving block 12, one side of the driving block 12 is provided with a reset spring 13, an inner block 14 is integrally arranged on the inner wall of the air inlet pipe 4, one side of the adjusting frame 8 is slidably provided with a fixing block 15, one side of the fixing block 15 is provided with a fixing spring, one side of the air inlet pipe 4 is integrally provided with an outer block 16, the number of the outer block 16 is multiple, one side of the rotating pipe 6 is slidably provided with a release rod 17, the release rod 17 and the rotating pipe 6 are provided with a compression spring 18, one side of the release rod 17 is integrally provided with a release block 23, the inside of the pipe body 1 is provided with a release slot 19, the surface of the release slot 19 is inserted with the release block 23, the middle of the air inlet pipe 4 is provided with a bearing, the bottom of the adjusting ring 2 is provided with a spray outlet 20, one side of the pipe body 1 is provided with an external interface 21, the outer side of the adjusting ring 2 is integrally provided with a gear ring 22, and one side of the gear ring 22 is engaged with the air inlet pipe 4.
