Description

Connecting structure of residue-free conveying pipeline

Technical Field

The utility model relates to a concentrate feed technical field, in particular to no residual pipeline connection structure.

Background

The centralized feeding system is formed by a plurality of pipeline connection functional devices, and pipelines are always connected with one another. If the splicing mode is adopted, the wall of the pipeline can have fall to cause material blockage, and the material blockage can be mixed when another material is conveyed; if the welding mode is adopted, the welding seam is easily washed, so that the materials are doped. Either way, mixing is easily caused to affect the quality of the product.

It is therefore necessary to provide a pipe connecting structure to solve this problem.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a no residual pipeline connection structure can avoid pipeline seam card material to influence the product quality.

The utility model discloses a following technical scheme realizes above-mentioned purpose: the utility model provides a no residue pipeline connection structure, includes first pipeline port and the second pipeline port with the pipe diameter, first pipeline port with all be equipped with the flange on the relative terminal surface of second pipeline port, the clamp is through two flanges with first pipeline port and the coaxial fixed of second pipeline port.

Specifically, the end face of the flange is provided with a circular groove, and a sealing ring is clamped between the two circular grooves.

Specifically, the clamp comprises a first semi-ring and a second semi-ring, the tail portions of the first semi-ring and the second semi-ring are hinged to each other, the free end of the second semi-ring is provided with a U-shaped portion, the free end of the first semi-ring is rotatably connected with a threaded pin, and the threaded pin can be embedded into the U-shaped portion and fixed through a nut sleeved on the threaded pin.

Furthermore, the rear part of flange is the shape of cone, the inboard V-arrangement groove that has the matching conical surface structure of clamp.

Furthermore, the tail end of the second half ring is also provided with an elastic sheet which can support the inner side of the first half ring.

Adopt above-mentioned technical scheme, the utility model discloses technical scheme's beneficial effect is:

the utility model discloses can avoid the pipeline seam residual material and influence the quality of product.

Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1 to 3, the utility model discloses a no residue pipeline connection structure, including first pipeline port 1a and second pipeline port 1b with the pipe diameter, all be equipped with flange 11 on the relative terminal surface of first pipeline port 1a and second pipeline port 1b, the clamp is through two flange 11 with first pipeline port 1a and the coaxial fixed of second pipeline port 1 b. The clamp can let the axial of first pipeline port 1a and second pipeline port 1b align voluntarily, avoids transition face between them to produce the step of easy card material. Therefore, the influence of residual materials on the quality of the product caused by the residual materials at the pipeline joint can be avoided.

As shown in fig. 3, the end surface of the flange 11 is provided with a circular groove (not shown), and the seal ring 3 is held between the two circular grooves. The sealing ring 3 has elasticity, and can seal the interface between the flanges 11, so as to avoid air leakage to influence the conveying effect. The sealing ring 3 also has a certain positive effect on the alignment of the two pipeline ports.

As shown in fig. 1, the clamp includes a first half ring 21 and a second half ring 22 hinged at the tail, the free end of the second half ring 22 has a U-shaped portion 221, the free end of the first half ring 21 is rotatably connected with a threaded pin 23, and the threaded pin 23 can be embedded into the U-shaped portion 221 and fixed by a nut 24 sleeved thereon. The clamp is convenient to operate, has rigidity, and can better realize the pipe orifice centering effect.

As shown in fig. 2 and 3, the rear portion of the flange 11 is tapered and the inside of the clip has V-shaped grooves (not labeled) that match the taper configuration. The V-shaped groove can be in slope contact with the flanges 11 on the two sides, when the hoop is tensioned, radial component force can be generated on the conical surfaces on the two sides, if axial deviation exists, the resultant force of the radial component force can adjust the two pipe openings to be centered, and therefore the purpose of avoiding the joint from having fall can be achieved.

As shown in fig. 1, the tail end of second half 22 is further provided with a spring 222 capable of supporting the inner side of first half 21. When the clamp is fixed, the elastic sheet 222 has a rebound force on the first half ring 21, so that the clamp can be prevented from loosening, and the problem of infirm connection of the pipe orifice is avoided.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
