Description

Technical Field

[0001] This utility model relates to the field of chemical safety production technology, specifically to a protective device for chemical safety production pipelines. Background Technology

[0002] As a pillar industry, chemical production plays a crucial role in my country's national economy. The main characteristics of chemical enterprises are the production of flammable, explosive, toxic, and high-temperature / high-pressure products. Chemical production processes generate a large number of chemical liquids and gases, thus requiring the use of numerous pipelines.

[0003] When a pipeline operates for an extended period, the amount of solid particles and impurities that accumulate gradually increases. If there are no devices in the pipeline to prevent the accumulation of solid particles and impurities, these particles and impurities will deposit and scale at various locations within the pipeline, making it difficult to clean the inside of the pipeline. This causes the inner diameter of the pipeline to continuously shrink, resulting in pipeline blockage. In severe cases, the material inside the pipeline may even be unable to flow, leading to production interruption. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] As attached Figure 2 and attached Figure 4 As shown, a protective device for pipelines in chemical safety production includes two sets of pipes 1 and a set of connecting sleeves 2. The ends of the two sets of pipes 1 are respectively installed inside the two ends of the connecting sleeves 2, and a filter plate 3 is installed inside one end of the connecting sleeves 2.

[0028] With the above structure, the two sets of pipes 1 are connected by the connecting sleeve 2, and the filter plate 3 is fixedly installed inside the connecting sleeve 2 to block solid particles and impurities. The connecting sleeve 2 is divided into two sections and is connected by threads. By separating the two sections of the connecting sleeve 2, it is convenient to replace the filter plate 3 and clean the solid particles and impurities accumulated inside the connecting sleeve 2. The specific structure is as follows:

[0029] Combined with appendix Figure 2 and attached Figure 3 As shown, threaded connecting pipes 4 are installed at both ends of the connecting sleeve 2. The pipe 1 passes through the inside of the threaded connecting pipe 4. A threaded sleeve 5 is rotatably installed on the outside of the pipe 1. The threaded sleeve 5 is installed on the outside of the threaded connecting pipe 4 with the thread. A sealing gasket is provided between the end of the pipe 1 and the inside of the threaded connecting pipe 4.

[0030] With the above structure, pipe 1 is inserted into threaded connecting pipe 4, and threaded sleeve 5 is installed on the outside of threaded connecting pipe 4 with thread, which drives pipe 1 to move into threaded connecting pipe 4. The sealing gasket makes the pipe 1 and threaded connecting pipe 4 sealed.

[0031] As attached Figure 2 and attached Figure 5 As shown, a mounting guide hole 6 is provided on one side wall of the connecting sleeve 2 away from the filter plate 3. An L-shaped tube 7 is installed through the mounting guide hole 6. The part of the L-shaped tube 7 located on the outside of the connecting sleeve 2 is fitted with a mounting plate 15. Two sets of bolts 16 are installed through the mounting plate 15. The outside of the connecting sleeve 2 is provided with threaded holes 17 for inserting the bolts 16. After the L-shaped tube 7 is inserted into the connecting sleeve 2 through the mounting guide hole 6, the mounting plate 15 is attached to the outside of the connecting sleeve 2. The two sets of bolts 16 are respectively inserted through the mounting plate 15 and installed into the corresponding threaded holes 17, thus fixing and sealing the L-shaped tube 7 on the connecting sleeve 2.

[0032] As attached Figure 5 and attached Figure 6 As shown, the L-shaped tube 7 has a rotating shaft 8 and a rotating shaft 11 passing through its two ends respectively. The ends of the rotating shaft 8 and the rotating shaft 11 located inside the L-shaped tube 7 are equipped with meshing bevel gears 10 and 14. The end of the rotating shaft 8 located outside the L-shaped tube 7 is equipped with a handwheel 9. The end of the rotating shaft 11 located outside the L-shaped tube 7 is equipped with a lever 12. The side of the lever 12 near the filter plate 3 is equipped with a cleaning brush 13 for cleaning the filter plate 3. The axis of the lower half of the L-shaped tube 7 is on the same straight line as the axis of the connecting sleeve 2, so that the lever 12 rotates around the axis of the connecting sleeve 2, which facilitates the comprehensive cleaning of the filter plate 3.

[0033] With the above structure, rotating the handwheel 9 drives the rotating shaft 8 and the bevel gear 10 to rotate. The bevel gear 10 meshes with the bevel gear 14, driving the rotating shaft 11 to rotate. The rotating shaft 11 drives the lever 12 to rotate. The cleaning brush 13 on the lever 12 cleans the filter plate 3, preventing solid particles and impurities from accumulating on the filter plate and clogging it.

[0034] Example 2

[0035] Based on Example 1, please refer to the appendix. Figure 1 The outer side of the connecting sleeve 2 is covered with a protective cover 18. The protective cover 18 is a round tube formed by rotating and connecting two sets of cover bodies with the same structure. The two ends of the protective cover 18 are clamped on the outside of the pipe 1. The corresponding sides of the two sets of cover bodies in the protective cover 18 are respectively connected to connecting plates 19. Multiple sets of bolts 20 pass through the two sets of connecting plates 19 for fixed connection.

[0036] The protective cover 18 has a U-shaped groove 21 between a set of covers and a connecting plate 19, through which the rotating shaft 8 passes, so that the protective cover 18 can be installed on the outside of the connecting sleeve 2 without affecting the cleaning of the filter plate 3.

[0037] With the structure described in Embodiment 2, the protective cover 18 is placed on the outside of the connection between the pipe 1 and the connecting sleeve 2 to protect the connection between the pipe 1 and the connecting sleeve 2, preventing accidental contact that could loosen the connection between the pipe 1 and the connecting sleeve 2 and cause product leakage.
