Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a lime powder conveying pipeline connector. Background Art

[0002] Lime powder is a white powdery substance with calcium carbonate as the main component. It has a wide range of applications. The most common one is used in the construction industry, that is, industrial calcium carbonate. The other is food-grade calcium carbonate, which is a common calcium supplement and is widely used. In processing and production, lime powder is usually transported by pipeline. There are also various ways to connect lime powder delivery pipelines. Pipeline connectors are more important in the transportation of lime powder.

[0003] At present, the connection modes of lime powder conveying pipelines are mostly threaded connection or flange connection. There are dead angles at the connection points, which may cause lime powder to be retained. This may cause the pipeline to be blocked for a long time. In addition, after the existing pipeline connector is bumped, it is easy to cause the pipeline connector to be damaged, thereby causing lime powder to leak. The disassembly and replacement of the existing pipeline connector is also relatively cumbersome, and the flange is easy to loosen after being used for a long time. Therefore, a lime powder conveying pipeline connector is proposed to address the above problems. Utility Model Content

[0004] The utility model aims to provide a lime powder conveying pipeline connector to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A lime powder conveying pipeline connector comprises a left pipeline, wherein a first clamping block is fixedly connected to a side of the left pipeline close to the right pipeline, and a second clamping block is fixedly connected to a side of the right pipeline close to the left pipeline, a convex ring is fixedly connected to the middle of an end of the first clamping block away from the left pipeline, a groove is provided in the middle of an end of the second clamping block away from the right pipeline, an inner liner is provided between the first clamping block and the second clamping block, a sealing ring is fixedly connected to the middle of the outer side of the inner liner, a semi-open ring is provided on the outer side of the first clamping block and the second clamping block, an anti-collision pad is fixedly connected to the outer edge of the semi-open ring, a trapezoidal clamping groove is provided on the inner side of the semi-open ring, a fixing block is fixedly connected to one side of the semi-open ring, a circular hole is provided on one side of the fixing block, a bolt is provided on the inner side of the circular hole, an elastic gasket is provided on the outer side of the bolt, and a nut is spirally connected to the outer side of the bolt.

[0007] Preferably, the first snap-fit ​​block is the same size as the second snap-fit ​​block, the convex ring and the groove have the same volume, the outer diameter of the liner is the same as the inner diameter of the left pipe, the diameter of the sealing ring is the same as the diameter of the groove, and the thickness of the sealing ring is slightly larger than the thickness of the groove.

[0008] Preferably, the number of the semi-open rings is two, the number of the anti-collision pads is four, and the number of the trapezoidal engaging grooves is two.

[0009] Preferably, the number of the fixing blocks is four, and the fixing blocks are symmetrically distributed on both sides of the semi-open ring, and the number of the circular holes is eight.

[0010] Preferably, the number of the bolts, elastic washers and nuts is eight, and the inner diameter of the elastic washers is slightly larger than the outer diameter of the bolts.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, the dead angles in the pipe connector are reduced by arranging the first engaging block, the second engaging block, the convex ring, the groove, the liner and the sealing ring. The convex ring and the groove press the sealing ring to seal the pipe. The liner inside the sealing ring fills the dead angles of the pipe connector. The lime powder will not be retained when passing through the pipe connector. The anti-collision pad located at the outer edge of the semi-open ring greatly reduces the damage to the pipe connector when it is bumped.

[0013] 2. In the utility model, by providing a semi-open ring, a trapezoidal snap-fitting groove, a fixing block, a round hole, a bolt, an elastic gasket and a nut, when in use, it is only necessary to put the liner into the inner side of the first snap-fitting block, align the first snap-fitting block and the second snap-fitting block, snap the trapezoidal snap-fitting groove provided on the semi-open ring into the first snap-fitting block and the second snap-fitting block, and tighten the bolts to successfully install the pipe connector, making it more convenient to disassemble and replace the pipe connector. The elastic gasket located on the outside of the bolt greatly reduces the possibility of the bolt loosening. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The first snap-fitting block 3 and the second snap-fitting block 4 are of the same size, the convex ring 5 and the groove 6 have the same volume, the outer diameter of the liner 7 is the same as the inner diameter of the left pipe 1, the diameter of the sealing ring 8 is the same as the diameter of the groove 6, the thickness of the sealing ring 8 is slightly larger than the thickness of the groove 6, the liner 7 can be inserted between the first snap-fitting block 3 and the second snap-fitting block 4, the number of semi-open rings 9 is two, the number of anti-collision pads 10 is four, the number of trapezoidal snap-fitting grooves 11 is two, the number of fixing blocks 12 is four, and the fixing blocks 12 are symmetrically distributed on both sides of the semi-open ring 9, the number of circular holes 13 is eight, the number of bolts 14, elastic washers 15 and nuts 16 are all eight, and the inner diameter of the elastic washers 15 is slightly larger than the outer diameter of the bolts 14.

[0025] Working process: When in use, first put the liner 7 into the inner side of the first snap-fitting block 3, align the first snap-fitting block 3 with the second snap-fitting block 4 and close them. At this time, the sealing ring 8 will be snapped into the groove 6, and the convex ring 5 is located on the side of the sealing ring 8 away from the groove 6. Then pick up the semi-open ring 9, and insert the trapezoidal snap-fitting groove 11 set on the semi-open ring 9 into the first snap-fitting block 3 and the second snap-fitting block 4. Put the elastic gasket 15 on the outside of the bolt 14, insert the bolt 14 into the round hole 13 on the fixing block 12, use the nut 16 to screw on the outside of the bolt 14 and tighten it. At this time, the trapezoidal groove transfers the pressure applied by the bolt 14 to between the first snap-fitting block 3 and the second snap-fitting block 4, and the pressure between the first snap-fitting block 3 and the second snap-fitting block 4 The sealing ring 8 is subjected to the pressure of the convex ring 5 and the groove 6 and fits tightly with the convex ring 5 and the groove 6, thereby ensuring the sealing of the device. The liner 7 located inside the first clamping block 3 and the second clamping block 4 fills the dead angle in the pipe connector.

The elastic gasket 15 located on the outside of the bolt 14, when the bolt 14 is tightened, the elastic gasket 15 limits the bolt 14 from loosening easily. When the lime powder passes through, the lime powder directly enters the liner 7 from the left pipe 1, and then enters the right pipe 2, and the lime powder retained in the pipe connector is greatly reduced.
