Description

Technical Field

[0001] This utility model relates to a tightly connected pneumatic ash conveying adapter. Background Technology

[0002] In industrial production, pneumatic conveying, as an efficient and clean material transport method, is widely used in the conveying of powder materials. In the actual layout and operation of pneumatic ash conveying systems, situations often arise where the direction of the conveying pipeline needs to be changed. For example, due to limitations such as plant structure, equipment installation location, or process flow adjustments, the ash conveying pipeline cannot be laid in a straight line and needs to be turned and connected at specific locations.

[0003] Some existing adapters have insufficiently tight connections, making them prone to leaks during pneumatic conveying due to the high air pressure and pulsating fluctuations within the pipeline. This not only reduces conveying efficiency but can also lead to a series of safety hazards, such as dust leaks into the surrounding environment, threatening the health of operators, and even posing a risk of dust explosions in certain environments with explosive dust. Utility Model Content

[0004] The main objective of this invention is to provide a tightly connected pneumatic ash conveying adapter to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A tightly connected pneumatic ash conveying adapter includes an adapter pipe with flanges at both ends, insert pipes on the inner sides of both ends of the adapter pipe, a pressure plate on the top surface of the insert pipe, a groove on the end face of the flange, a spring between the bottom surface of the pressure plate and the bottom surface of the groove, a fixing block on the outer circumferential surface of the pressure plate, and a fixing groove on the end face of the flange outside the groove.

[0007] Preferably, the inner wall of the transfer tube is provided with a guide groove along its length, and the outer wall of the insertion tube is provided with a guide block that cooperates with the guide groove.

[0008] Preferably, four guide grooves are provided, and the four guide grooves are evenly distributed along the circumference of the adapter pipe.

[0009] Preferably, eight springs are provided, and the eight springs are evenly distributed between the bottom surface of the pressure plate and the bottom surface of the groove and along the circumference of the pressure plate.

[0010] Preferably, four fixing blocks are provided, and the four fixing blocks are evenly distributed on the outer peripheral surface of the pressure plate.

[0011] Preferably, the fixing block is provided with fixing holes.

[0012] Preferably, the thickness of the fixing block is equal to the depth of the fixing groove.

[0013] Preferably, the inner wall of one end of the insertion tube into the adapter tube is provided with a transition arc surface.

[0014] The beneficial technical effects of this utility model are as follows:

[0015] This invention effectively absorbs the impact force during pneumatic ash conveying by incorporating an insert pipe within the adapter pipe and a spring between the pressure plate and the groove, preventing loosening of the connection. When the adapter is connected to other pipes, the pressure plate is pressed down, the spring is compressed, and the position of the pressure plate is restricted by the fixing block and the fixing groove. When pressed to the lowest point, it will not continue to descend and create gaps, and the spring can always maintain an upward reaction force, thus ensuring a tight connection between the adapter and other pipes and providing a strong guarantee for the stable operation of the pneumatic ash conveying system.

[0023] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0024] like Figures 1-6As shown, the tightly connected pneumatic ash conveying adapter provided in this embodiment includes an adapter pipe 1, flanges 2 at both ends of the adapter pipe 1, insert pipes 3 on the inner sides of both ends of the adapter pipe 1, a pressure plate 4 on the top surface of the insert pipe 3, a groove 5 on the end face of the flange 2, a spring 6 between the bottom surface of the pressure plate 4 and the bottom surface of the groove 5, a fixing block 7 on the outer circumferential surface of the pressure plate 4, and a fixing groove 8 on the end face of the flange 2 outside the groove 5.

[0025] In the initial state, the pressure plate 4 is pushed out of the groove 5 by the spring 6, ensuring that the spring 6 is in a compressed state when connecting other pipes. The two ends of the spring 6 are fixedly connected to the bottom surface of the pressure plate 4 and the bottom surface of the groove 5.

[0026] During connection, the end faces of other pipes press the protruding pressure plate 4 back into the groove 5, while the bottom surface of the fixing block 7 fits against the fixing groove 8. At this point, the end faces of the pressure plate 4 and the flange 2 are on the same plane, and finally, bolts are used to fix the connection. When connecting with other pipes, conventional methods such as sealing gaskets can be used between the adapter and other pipes to further ensure a tight connection.

[0027] After the connection is completed, spring 6 can effectively absorb the impact force brought by pneumatic ash conveying and prevent the connection from loosening.

[0028] In this embodiment, as Figure 4 As shown, the inner wall of the adapter tube 1 is provided with a guide groove 9 along its length, and the outer wall of the insertion tube 3 is provided with a guide block 10 that works in conjunction with the guide groove 9. The guide groove 9 provides precise guidance for the insertion of the insertion tube 3, ensuring that the insertion tube 3 can be accurately and smoothly inserted into the adapter tube 1, and when the pressure plate 4 is pressed, it can ensure that it moves downward in the correct direction, thus ensuring connection stability.

[0029] In this embodiment, as Figure 5 As shown, four guide grooves 9 are provided. The four guide grooves 9 are evenly distributed along the circumference of the adapter tube 1, providing stable guiding force from four directions. This ensures that the insertion tube 3 maintains good alignment during insertion, avoiding tilting or jamming caused by uneven local force, and ensuring that the insertion tube 3 can move evenly and smoothly within the adapter tube 1.

[0030] In this embodiment, as Figure 5 As shown, eight springs 6 are provided. These eight springs 6 are evenly distributed around the bottom surface of the pressure plate 4 and the bottom surface of the groove 5, providing a more balanced elastic force and ensuring a tight connection. At the same time, the evenly distributed springs 6 can effectively disperse pressure, preventing damage or deformation of components due to excessive local pressure, and extending the service life of the springs 6 and the adapter.

[0031] In this embodiment, as Figure 6As shown, there are four fixing blocks 7. The four fixing blocks 7 are evenly distributed on the outer circumferential surface of the pressure plate 4 and along its circumference. They can provide stable support and positioning for the pressure plate 4 and prevent the pressure plate 4 from rotating or shifting during operation.

[0032] In this embodiment, as Figure 6 As shown, the fixing block 7 is provided with fixing holes 11 for easy bolt connection.

[0033] In this embodiment, as Figure 2 As shown, the thickness of the fixing block 7 is equal to the depth of the fixing groove 8, which restricts the displacement of the pressure plate 4 so that it cannot continue to move downward and prevents gaps from appearing between the pipe connections.

[0034] In this embodiment, as Figure 3 As shown, the inner wall of the end of the insertion tube 3 that is inserted into the adapter tube 1 is provided with a transition arc surface, so that the dust can pass through smoothly during the pneumatic dust conveying process and will not accumulate at the corner.

[0035] In summary, in this embodiment, by installing an insert 3 inside the adapter pipe 1 and a spring 6 between the pressure plate 4 and the groove 5, the impact force brought by pneumatic ash conveying can be effectively absorbed, preventing the connection from loosening. When the adapter is connected to other pipes, the pressure plate 4 is pressed down, and the spring 6 is compressed. At the same time, the position of the pressure plate 4 is restricted by the fixing block 7 and the fixing groove 8. When pressed to the lowest point, it will not continue to move downwards and cause gaps. The spring 6 can always maintain an upward reaction force, thereby ensuring a tight connection between the adapter and other pipes, providing a strong guarantee for the stable operation of the pneumatic ash conveying system.

[0036] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
