Description

Technical Field

[0001] The utility model relates to the technical field of pipeline repair, in particular to a nozzle structure of anti-corrosion mortar spraying equipment. Background Art

[0002] Anti-corrosion mortar spraying in pipeline repair is a specific repair technology, which is mainly used to enhance the corrosion resistance of pipelines, form an anti-corrosion mortar layer on the surface of pipelines, reinforce pipelines, and realize pipeline repair.

[0003] The anti-corrosion mortar spraying equipment mainly includes a mixing box, a pump group, a pipeline and a nozzle. Since most spraying equipment usually adopts a single nozzle form during the spraying process inside the pipeline, uneven spraying is very likely to occur. Therefore, during the spraying process of the inner wall of the pipeline, an annular nozzle is often used for spraying. The annular nozzle can increase the coverage range and ensure a good spraying effect on the inner wall of the pipeline. However, when the current annular nozzle is used to transport mortar, some branch pipelines are blocked, which will cause some nozzles to fail, resulting in uneven spraying. Moreover, the internal pipeline transportation form of the annular nozzle is single, which can easily lead to unstable pressure, thereby reducing the spraying effect. In view of the shortcomings of the existing technology, the utility model provides an anti-corrosion mortar spraying equipment nozzle structure to solve the above problems. Utility Model Content

When the anti-corrosion mortar adheres to the inner wall of the pipeline, the pipeline is repaired. At the same time, multiple groups of pressure reducing pipes are added. The set pressure reducing pipes can reduce the pressure of the traditional conveying method of the main conveying pipe and the branch pipe. On the one hand, it prevents the branch pipe from being unable to spray when it is blocked. On the other hand, it ensures that the pressure between each nozzle body is stable, so that the anti-corrosion mortar is sprayed evenly and the pipeline adsorption effect is good.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a nozzle structure for anti-corrosion mortar spraying equipment, comprising an output pipe of the spraying equipment and a joint body threadedly connected to the output pipe of the spraying equipment, the joint body being provided with a main delivery pipe, the main delivery pipe being provided with multiple groups of branch pipes, and the branch pipes being fixedly connected to a delivery ring;

[0006] The conveying ring is threadedly connected to a plurality of nozzle bodies;

[0007] A plurality of pressure reducing pipes are connected between the conveying ring and the main conveying pipe.

[0008] Preferably, an inner sealing ring is movably clamped inside the joint body, and the inner sealing ring is clamped between the output pipe of the spraying device and the joint body.

[0009] Preferably, a first pressing ring is provided on the output pipe of the spraying device, and an outer sealing ring is movably clamped between the first pressing ring and the joint body.

[0010] Preferably, a threaded port is provided on the conveying ring, a threaded pipe is provided on the spray head body, and the threaded pipe is threadedly connected inside the threaded port.

[0011] Preferably, a second pressing ring is fixedly connected to the threaded pipe.

[0014] Through the design of the main conveying pipe, branch pipes, conveying ring and multiple groups of spray head bodies, the spray head structure of the anti-corrosion mortar spraying device facilitates the transmission of the anti-corrosion mortar conveyed by the output pipe of the spraying device and the joint body and the spraying by the spray head bodies. When the anti-corrosion mortar adheres to the inner wall of the pipeline, pipeline repair is realized.

[0022] By providing a nozzle structure of an anti-corrosion mortar spraying device in the embodiments of the present application, the problems that when the current annular nozzle conveys mortar, after some branch pipelines are blocked, some nozzles will fail, resulting in uneven spraying, and moreover, the internal pipeline conveying form of the annular nozzle is single, which easily leads to unstable pressure and further reduces the spraying effect are solved.

[0023] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific implementation manners.

[0024] An embodiment of the present utility model discloses a nozzle structure of an anti-corrosion mortar spraying device. As shown in the attached Figures 1-4 figure, it includes a spray equipment output pipe 1 and a joint body 2 threadedly connected to the spray equipment output pipe 1. An inner sealing ring 201 is movably clamped inside the joint body 2. The inner sealing ring 201 is clamped between the spray equipment output pipe 1 and the joint body 2. A first compression ring 101 is provided on the spray equipment output pipe 1. An outer sealing ring 102 is movably clamped between the first compression ring 101 and the joint body 2;

[0025] When the spray equipment output pipe 1 and the joint body 2 are docked, through the design of the inner sealing ring 201, when the spray equipment output pipe 1 and the joint body 2 are tightened, the inner sealing ring 201 is extruded to form a preliminary seal. At the same time, the first compression ring 101 will also extrude the outer sealing ring 102 with the joint body 2 to form a secondary seal at the connection position of the spray equipment output pipe 1 and the joint body 2, ensuring the stable connection and good sealing performance of the spray equipment output pipe 1 and the joint body 2.

[0026] The joint body 2 is provided with a main conveying pipe 3. A plurality of groups of branch pipes 4 are provided on the main conveying pipe 3.

[0027] The device is designed with a main conveying pipe 3, branch pipes 4, a conveying ring 5 and multiple groups of nozzle bodies 6, which facilitates the transmission of the anticorrosive mortar conveyed by the output pipe 1 of the spraying device and the joint body 2 and the ejection by the nozzle bodies 6. When the anticorrosive mortar adheres to the inner wall of the pipeline, the pipeline repair is realized.

[0028] Multiple groups of decompression pipes 7 are connected between the conveying ring 5 and the main conveying pipe 3. The set decompression pipes 7 reduce the pressure of the traditional conveying mode of the main conveying pipe 3 and the branch pipes 4. On the one hand, it prevents the inability to spray when the branch pipes 4 are blocked. On the other hand, it ensures the stable pressure before each nozzle body 6, so that the anticorrosive mortar is evenly sprayed and the adsorption effect of the pipeline is good.

[0029] The conveying ring 5 is provided with a threaded port 501, and the nozzle body 6 is provided with a threaded pipe 601. The threaded pipe 601 is threadedly connected in the threaded port 501.

[0030] Through the design of the threaded port 501 and the threaded pipe 601, the device makes the disassembly and assembly of the nozzle body 6 convenient, so that the nozzle body 6 is easy to maintain. At the same time, with the cooperation of the design of the second compression ring 602 and the secondary sealing ring 603, when the nozzle body 6 is installed and tightened, the second compression ring 602 squeezes the secondary sealing ring 603, so that the sealing performance between the nozzle body 6 and the conveying ring 5 is good.
