Description

Technical Field

[0001] The utility model relates to the technical field of blockage detection and positioning of material conveying pipelines, in particular to a blockage point detection and positioning structure of a long material conveying pipeline. Background Art

[0002] In material transportation, pipeline blockage is a long-standing problem, which seriously affects the efficiency and stability of material transportation.

[0003] The traditional method of detecting pipeline blockage mainly relies on pressure sensors to monitor the gas source pressure. Under normal working conditions, the gas source pressure should be maintained at around 2.5 atmospheres. However, when a blockage occurs inside the pipeline, the gas source pressure will become abnormal, usually manifested as a pressure increase.

[0004] For long-distance material transportation pipelines, the blockage problem is particularly difficult. Since the pipeline length may reach one or two hundred meters, once a blockage occurs, it becomes very difficult to accurately locate the blockage point. The traditional disassembly inspection method is time-consuming and laborious, and may cause damage to the pipeline system. In addition, new failure points may be introduced during the disassembly and reinstallation process, increasing maintenance costs.

[0005] At present, there is no effective automated solution in the industry to quickly and accurately detect and locate pipeline blockages. Most existing methods rely on manual inspections and feedback from pressure sensors. Although this method can detect the occurrence of blockages, it cannot accurately point out the specific location of the blockage, resulting in low maintenance efficiency.

[0006] Therefore, how to quickly and accurately detect and locate the blockage point in the material conveying pipeline has become a technical problem to be solved by the utility model. Utility Model Content

[0007] The technical problem solved by the utility model is to provide a blockage point detection and positioning structure for a long material conveying pipeline in view of the defects existing in the above-mentioned prior art, so as to solve the problem that the blockage point in the material conveying pipeline cannot be detected quickly and accurately proposed in the above-mentioned background technology.

[0008] In order to solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0009] A blockage point detection and positioning structure for a long material conveying pipeline comprises a material conveying pipeline, a compressed air pipeline, a solenoid valve mechanism, a material pipe and a material bin;

[0010] More than three solenoid valve mechanisms are evenly distributed in the length direction between the feeding pipeline and the compressed air pipeline;

[0011] The solenoid valve mechanism comprises a first solenoid valve and a pipeline, wherein the first solenoid valve for controlling the on-off of the pipeline is arranged on the pipeline, one end of the pipeline is connected to the feeding pipeline, and the other end of the pipeline is connected to the compressed air pipeline, and the compressed air pipeline is connected to a compressed air source;

[0012] On the feeding pipeline, a material pipe communicating with the feeding pipeline is arranged between two adjacent solenoid valve mechanisms, and the material pipe is connected to the material bin in an on-off manner through the second solenoid valve.

[0013] As a further solution of the present invention, the compressed air pipe is an air pipe made of PU material.

[0014] As a further solution of the utility model, additional joints are evenly distributed on the compressed air pipeline to facilitate maintenance and replacement.

[0015] As a further solution of the utility model, each additionally installed joint is equipped with a first solenoid valve for remotely controlling the on and off of the airflow.

[0016] As a further solution of the utility model, the feeding pipe is made of stainless steel and is provided with a smooth inner wall coating to reduce resistance during material transportation.

[0017] As a further solution of the utility model, the pipeline in the solenoid valve mechanism is made of flexible material to adapt to different bends and angles between the feeding pipeline and the compressed air pipeline.

[0018] Compared with the prior art, the beneficial effects of the utility model are: for the detection of blockage points in long material conveying pipelines, the blockage points can be quickly and accurately located through changes in airflow, avoiding the need for manual inspections and reliance on pressure sensor feedback structures that are complex, time-consuming and labor-intensive, and helping to improve maintenance efficiency.

[0027] Embodiment 1:

[0028] This embodiment provides a blockage point detection and positioning structure for a long material conveying pipeline, and describes in detail how to use the structure to quickly and accurately detect and locate blockage points in the material conveying pipeline.

[0029] The blockage point detection and positioning structure of this embodiment includes a feed pipe 1, a compressed air pipe 2, a plurality of solenoid valve mechanisms 3, and a plurality of material pipes 4 and a material bin 5. The feed pipe 1 is made of stainless steel, and a smooth inner wall coating is provided inside to reduce the resistance of the material during transportation and improve the transportation efficiency. The compressed air pipe 2 adopts a PU air pipe with good pressure resistance and flexibility. In the length direction between the feed pipe 1 and the compressed air pipe 2, more than 3 solenoid valve mechanisms 3 are evenly distributed. Each solenoid valve mechanism 3 includes a first solenoid valve 6 and a pipeline 7, one end of the pipeline 7 is connected to the feed pipe 1, and the other end is connected to the compressed air pipe 2. The compressed air pipe 2 is also connected to a compressed air source 8 to provide stable compressed air.

[0030] In order to facilitate maintenance and replacement, additional connectors are evenly distributed on the compressed air pipeline 2, and each connector is equipped with a first solenoid valve 6 for remotely controlling the on and off of the airflow. This not only improves the reliability of the system, but also facilitates daily maintenance.

[0031] During normal operation, materials are transported through the feeding pipe 1. When a blockage occurs, a conventional pressure sensor may only detect the occurrence of the blockage, but cannot accurately locate the location of the blockage point. However, the structure of this embodiment can quickly and accurately detect and locate the blockage point.

[0032] The specific operation is as follows: First, starting from the power source of compressed air, gradually blow compressed air to each solenoid valve mechanism 3. Before blowing, make sure that all first solenoid valves 6 are in a closed state. Then, open each solenoid valve (i.e., the first solenoid valve 6 and the second solenoid valve 9) in turn, and blow compressed air again after each opening. By observing and monitoring the changes in airflow, the location of the blockage point can be determined.

[0033] For example, when a solenoid valve is opened, if the airflow suddenly weakens or the pressure drops significantly, it can be preliminarily determined that the feeding pipeline 1 near the first solenoid valve 6 is blocked. In this way, the specific location of the blockage point can be quickly located, thereby avoiding the cumbersome process of disassembling the entire pipeline for inspection in the traditional method. The blockage point detection and positioning structure of this embodiment not only improves the accuracy and efficiency of blockage point detection, but also reduces maintenance costs and reduces new fault points that may be introduced during disassembly and reinstallation.

[0034] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
