Abstract
Description
Technical Field
[0001] This utility model relates to the field of powder conveying technology, and specifically to a powder conveyor. Background Technology
[0002] Powder conveying is a common process in industrial production, and powder conveyors are widely used. However, traditional powder conveyors have many problems in their feed pipe design.
[0003] Traditional feed pipes typically consist of a single, long pipe. This design has significant drawbacks. First, the fixed length of the pipe makes it difficult to adjust to changes in actual production scenarios, failing to adapt to different installation spaces and conveying requirements. Second, a single, long pipe is prone to bending during use. Bending obstructs the flow of powder within the pipe, leading to blockages and affecting the efficiency and stability of powder conveying. Furthermore, when blockages occur, the monolithic design makes repairs difficult, requiring substantial time and manpower for troubleshooting and unblocking. Utility Model Content
[0004] In view of the deficiencies in the prior art, this utility model provides a powder conveyor.

[0022] The present invention will now be described in detail with reference to the accompanying drawings:
[0023] This embodiment provides a powder conveyor, which mainly consists of a negative pressure device 1, a feed pipe 4, and a discharge pipe 3. The negative pressure device 1 is provided with a feed inlet 2 and a discharge outlet. Several feed pipes 4 are connected to the feed inlet 2 in sequence through a connecting mechanism, and the discharge outlet is connected to the discharge pipe 3. The powder is drawn into the negative pressure device 1 through the feed pipes 4 and conveyed to the required position through the discharge pipe 3.
[0024] Connection mechanism structure and connection method:
[0025] The connecting mechanism includes a first flange 5, a second flange 8, and a third flange 12.
[0026] First flange 5: Guide pins 6 are arranged in a circular array along the first flange 5, and limit blocks 7 are connected to the guide pins 6. The first flange 5 is provided at the feed port 2 and one end of the feed pipe 4.
[0027] Second flange 8: The second flange 8 is provided with an arc-shaped groove 9 that mates with the guide pin 6. A through hole 10 is located at one end of the arc-shaped groove 9, and the through hole 10 mates with the limiting block 7. The second flange 8 is provided with a circumferential array of slots 11. The other end of the feed pipe 4 is provided with the second flange 8.
[0028] Third flange 12: The third flange 12 is provided with a locking block 14 that mates with the locking groove 11, and a limiting groove 13 that mates with the limiting position. The second flange 8 and the third flange 12 are provided with mating threaded holes 15, and a hand-tightening screw 16 is installed in the threaded hole 15. The third flange 12 is slidably mounted on the feed pipe 4.
[0029] Feed pipe 4 splicing process:
[0030] When splicing the feed pipes 4, first align the first flange 5 at one end of one feed pipe 4 with the second flange 8 at the other end of the other feed pipe 4, so that the guide pin 6 on the first flange 5 is inserted into the arc-shaped groove 9 of the second flange 8 through the through hole 10. Then rotate the first flange 5 so that the limiting block 7 moves away from the position of the through hole 10, completing the initial connection.
[0031] Next, the third flange 12, which is slidably mounted on the feed pipe 4, is moved to a position where it fits against the second flange 8, so that the locking block 14 on the third flange 12 is engaged in the locking groove 11 of the second flange 8, and the limiting block 7 is engaged in the limiting groove 13 to prevent relative rotation between the first flange 5 and the second flange 8.
[0032] Finally, by tightening the hand screws 16 through the mating threaded holes 15 on the second flange 8 and the third flange 12, the second flange 8 and the third flange 12 are fixed together, thus completing the splicing of the two feed pipes 4. Following the same method, multiple feed pipes 4 can be spliced sequentially to form a feed pipe of the required length. The feed pipe 4 at the end does not have a second flange 8, which serves as a suction nozzle during material suction.
[0033] After the four feed pipes are spliced together, they are spliced together to the feed inlet 2 of the negative pressure equipment 1 in the same way.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
