[0013] Compared with the prior art, the utility model provides a pneumatic conveying pipeline blockage removal device, which has the following

[0014] Beneficial effects:

[0015] In the technical solution disclosed by the utility model, the ultrasonic generator converts high-frequency ultrasonic waves into high-frequency vibrations through a transducer electrically connected at one end. The transducer fits the bottom surface of the conveying pipe through a base, and the high-frequency vibrations are transmitted to the interior of the conveying pipe, so that the particles accumulated and blocked inside are gradually vibrated and scattered on the inner bottom wall of the conveying pipe, thereby solving the internal blockage problem.

Since the transducer fits the bottom surface of the conveying pipeline through the bottom support, the high-frequency vibration is transmitted to the inside of the conveying pipeline, and the particles blocked inside are vibrated at high frequency, so that the accumulated blockages are dispersed by the high-frequency vibration and spread flatly on the inside of the conveying pipeline to be unblocked. This scheme is suitable for unblocking particles that are heavier in themselves, thereby achieving the purpose of improving the scope of application of the unblocking device and being more practical.

DETAILED DESCRIPTION

[0023] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Figure 1-Figure 4 An embodiment of the utility model is a pneumatic conveying pipeline blockage removal device, comprising a conveying pipeline 1, a bottom surface of the conveying pipeline 1 is provided with a base 2, and a top plate 4 is fixed to the side of the base 2 by a hinge 3, a threaded hole is provided on the bottom surface of the base 2, and a blockage removal component 5 is threadedly connected to the internal thread of the threaded hole, and a mounting structure 6 is threadedly connected to the top surface of the top plate 4.

[0025] The specific problem addressed by this specific embodiment is to solve the problem that for particles with high density and large weight, the impact generated by the release of high-pressure gas cannot disperse and evacuate the accumulated particles. This solution has a poor blocking effect on particles with large weight and a small scope of application. The utility model uses an ultrasonic generator 52 to convert high-frequency ultrasonic waves into high-frequency vibrations through a transducer 51 electrically connected at one end. The transducer 51 fits the bottom surface of the conveying pipe 1 through the base 2. The high-frequency vibration is transmitted to the inside of the conveying pipe 1, so that the particles accumulated and blocked inside gradually vibrate and scatter on the inner bottom wall of the conveying pipe 1, solving the internal blockage problem. It is applicable to the case of blockage by heavier particles.

[0026] The blockage removal component 5 includes a transducer 51 threadedly connected to the threaded hole, and the surface of the transducer 51 is electrically connected to an ultrasonic generator 52, a heat dissipation port is provided on the top surface of the ultrasonic generator 52, and a heat dissipation silicone pad 53 is provided inside the heat dissipation port. In this specific embodiment, according to the blockage position inside the conveying pipeline 1, the bottom bracket 2 and the top plate 4 are placed outside the blockage position, and the bolt 9 is screwed to fix it on the surface of the conveying pipeline 1. Then, the screw 61 is screwed to drive the clamping plate 63 fixed at one end by the bearing 62 to move and squeeze it on the surface of the conveying pipeline 1, so that The base 2 is attached to the bottom surface of the conveying pipe 1. Finally, the ultrasonic generator 52 works, so that the transducer 51 electrically connected at one end thereof converts ultrasonic waves into high-frequency vibrations. Since the transducer 51 is attached to the bottom surface of the conveying pipe 1 through the base 2, the high-frequency vibrations are transmitted to the inside of the conveying pipe 1, and high-frequency vibrations are performed on the particles blocked inside, so that the accumulated blockages are dispersed by the high-frequency vibrations and spread flatly on the inside of the conveying pipe 1, so that they can be unblocked. This solution is suitable for unblocking particles that are heavier in themselves, thereby achieving the purpose of improving the scope of application of the unblocking device and being more practical.

[0028] By setting the screw block 7, an external screwdriver is inserted into the opening and then the screw block 7 is twisted to drive the screw rod 61 to rotate, so that the clamping plate 63 can fit the surface of the conveying pipe 1 more firmly. At the same time, the anti-slip texture provided on the bottom surface of the rubber pad 8 can greatly increase its contact with the surface of the conveying pipe 1 to avoid loosening.
