Description

Technical Field

[0001] The utility model belongs to the technical field of special vehicles and pneumatic conveying pipelines, and specifically relates to a step-free quick connector. Background Art

[0002] Quick connectors are used in the material conveying pipeline system of tank vehicles. Tank vehicles refer to special vehicles and car trains equipped with tank-shaped containers and usually equipped with working pumps for transporting liquids, gases or powdered substances, as well as completing specific work tasks. In the field of environmental protection, bulk granular activated carbon used for VOCs waste gas treatment is transported in logistics by a vertical tank transport vehicle. The bulk granular activated carbon needs to be transported by positive pressure pneumatic force to the activated carbon adsorption box on the top of the plant.

[0003] Pneumatic conveying uses the energy of airflow to transport powdered and granular materials along the direction of airflow in a closed pipe. It is a specific application of fluidization technology. The material conveying pipes in the pneumatic conveying system are connected by flanges for easy maintenance and disassembly.

[0004] However, the existing material conveying pipeline system has the following disadvantages:

[0005] Due to the activity of bulk columnar particles, they are easily collided with the step surface of the standard quick connector at the pipeline connection during pneumatic conveying, resulting in material damage and affecting the original physical state of the medium, which cannot meet market and technical requirements. Utility Model Content

[0006] The utility model provides a step-free quick connector, which solves the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a step-free quick connector, including a female end and a male end snap-connected with the female end, and the connection between the female end and the male end is set without steps.

[0008] Preferably, the female end includes a female end pipe, a sleeve a integrated with the female end pipe and connected to the female end pipe, an annular groove a opened along the circumferential direction of the sleeve a, two groups of fixing units a rotatably connected in the annular groove a and symmetrically arranged, and a silicone pad a arranged inside the sleeve a.

[0009] Preferably, the male end includes a male end pipe a, a connecting portion a arranged at the front end of the male end pipe a, and an arc groove a opened along the circumferential direction of the connecting portion a.

[0010] Preferably, the inner diameters of the female end pipe and the male end pipe a are the same, and the sleeve a is provided with a through hole a adapted to the fixing unit a.

[0011] Preferably, it also includes a plugging cover adapted to the male end, the plugging cover includes a sleeve b, an annular groove b opened along the circumferential direction of the sleeve b, two groups of fixing units b rotatably connected in the annular groove b and symmetrically arranged, and a silicone pad b arranged inside the sleeve b, a through hole b adapted to the fixing unit b is opened on the sleeve b, and one end of the sleeve b is configured to be sealed.

[0012] Preferably, it also includes a welding male end that is adapted to the female end, wherein the welding male end includes a male end pipe b, a connecting portion b arranged at the front end of the male end pipe b, and an arc groove b opened along the circumferential direction of the connecting portion b, and the length of the male end pipe b is smaller than that of the male end pipe a.

[0013] The beneficial effects of adopting the above technical solution are:

[0014] By customizing the quick connector, the gap between the quick connector and the seamless pipe is eliminated. For example, the inner diameter of the 3-inch standard quick connector is 70mm, and the inner diameter of the 89*4 seamless pipe used for docking is 81mm. For this reason, the size of the quick connector is adjusted to 81mm, so that there is no step surface at the transition connection, thereby reducing the damage between the material and the pipe and reducing the damage rate of the unloading medium.
