Technical Field

[0001] The utility model belongs to the technical field of warning devices, and particularly relates to a chemical equipment failure warning device. Background Technique

[0002] Chemical equipment refers to various machinery and devices used in chemical industrial production, mainly including chemical machinery and chemical static equipment. Chemical equipment plays a crucial role in the chemical production process, helping to convert raw materials into finished products. Chemical equipment can be divided into two categories: chemical dynamic equipment and chemical static equipment. The main functional components of chemical dynamic equipment are moving machinery, such as various pumps, compressors, and fluid conveying machinery, etc.; while the main functional components of chemical static equipment are static or machinery with very little movement, such as containers, reactors, heat exchangers, etc.

[0003] In existing chemical equipment, there are often many problems related to the transportation of chemical gases. Generally, chemical gases are transported through pipelines, and there are many joints in the transportation pipelines. Such joints are extremely prone to leakage of chemical gases. In the existing technology, in order to monitor the leakage situation at the joints, personnel will set up detection and warning devices at the pipeline joints. The most commonly used one is to install a cover at the joint of the chemical gas pipeline and then install sensors to detect gas leakage, so as to give an early warning of the leakage in a timely manner. However, during the actual installation of the existing detection devices, the applicant found that the existing detection cover structures are customized according to the diameter of the pipeline and cannot be fixedly installed and used on chemical gas pipes with different diameters. The installation versatility of the entire cover structure is poor. In order to solve the above-mentioned problems, a chemical equipment failure warning device is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a chemical equipment failure warning device in order to solve the above-mentioned problems.

A chemical gas detection sensor is hermetically connected to one of the covers. Connecting plates are welded on both side walls of the two covers, and the connecting plates on the two covers can be fixedly connected together by bolts. Semi-circular grooves are opened on the inner walls at both ends of the cover. A convex strip is constructed on the outer wall of the semi-circular sealing plate, and the convex strip is adaptively clamped with the groove. A semi-circular groove is opened at the center of the semi-circular sealing plate, and the diameter of the semi-circular groove has multiple size options according to the outer diameter of the pipeline.

[0006] In a preferred embodiment, the chemical gas detection sensor can be selected and adapted according to different chemical gases.

[0007] In a preferred embodiment, the inner and outer diameters in the middle of the cover are larger than those at both ends.

[0008] In a preferred embodiment, a first sealing gasket is provided between the connecting seams of the connecting plates on the two cover bodies.

[0009] In a preferred embodiment, a second sealing gasket is provided between the connecting seam of the rib and the clamping groove.

[0010] In a preferred embodiment, a third sealing gasket is provided at the combined docking connection of the two semi-circular sealing plates.

[0011] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0012] 1. In the present utility model, by adjusting the semi-circular sealing plates with semi-circular grooves of different diameters, the cover body can be installed and used with chemical gas pipes of different diameters, and at the same time, it can also be used to fix the reducer joint of the chemical pipeline, improving the versatility and practicality of the structure.

[0013] 2. In the present utility model, sealing gaskets are provided at the connections between the cover body, the semi-circular sealing plates and the chemical gas pipe, so as to form a sealed space inside the cover body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] The following will be combined with Figures 1-3 to give a detailed description of a chemical equipment fault warning device according to an embodiment of the present utility model.

[0020] Embodiment:

[0021] A chemical equipment fault warning device provided by an embodiment of the present utility model, as shown in reference to Figures 1 to 3 , includes two symmetrical cover bodies 1 and four semi-circular sealing plates 2. A chemical gas detection sensor 3 is installed on one of the cover bodies 1. Connecting plates 4 are welded on both side walls of the two cover bodies 1. The connecting plates 4 on the two cover bodies 1 can be fixedly connected together by bolts. Semi-circular grooves 5 are provided on the inner walls at both ends of the cover body 1. Convex strips 6 are formed on the outer wall of the semi-circular sealing plate 2. The convex strips 6 are adaptively clamped with the grooves 5. A semi-circular groove 7 is provided at the center of the semi-circular sealing plate 2. The diameter of the semi-circular groove 7 has multiple size options according to the outer diameter of the chemical gas pipeline. In this structure, personnel can select a semi-circular sealing plate 2 with a suitable semi-circular groove 7 according to the diameter of the chemical gas pipeline to be monitored and warned. Then, the convex strip 6 of the semi-circular sealing plate 2 is clamped with the groove 5 of the cover body 1. Then, the two cover bodies 1 are combined, and the connecting plates 4 are locked together by bolts. At this time, the two semi-circular sealing plates 2 can be butted and combined together to seal both ends of the cover body 1, so that the joint of the chemical gas pipeline is inside the cover body 1. In this way, when chemical gas leaks at the joint, the gas fills the cover body 1 fully. In this way, the chemical gas detection sensor 3 can detect the chemical gas leakage and give an alarm in time to play a warning role;

[0022] In the above structure, by adjusting the semi-circular sealing plates 2 with different diameters of semi-circular grooves 7, the cover body 1 can be installed and used with chemical gas pipes of different diameters. At the same time, it can also be used to fix the reduced-diameter joint of the chemical pipeline, improving the versatility and practicability of the structure.

[0023] As shown in reference to Figures 1 to 3 , the chemical gas detection sensor 3 can be adapted according to different chemical gases. There are various chemical gases, so the gas detection sensors are also different. The chemical gas detection sensor 3 in this application is just one of them. Which sensor to use specifically is determined by the gas being transported.

[0024] It should be noted that: the chemical gas detection sensors 3 involved in this application all adopt existing gas detection sensors, which are all publicly available equipment.

[0025] As shown in reference to Figures 1 to 3 , the inner and outer diameters of the middle of the cover body 1 are larger than those of both ends. At this time, the structure is convenient for the cover body 1 to adapt to the protrusion of the pipeline flange connection, ensuring the adaptability of the cover body 1.

[0026] As shown in reference to Figures 1 to 3As shown in the figure, a first sealing gasket 8 is provided between the connection seams of the connecting plates 4 on the two cover bodies 1, a second sealing gasket 9 is provided between the connection seams of the convex strips 6 and the clamping grooves 5, and a third sealing gasket 10 is provided at the combined docking joint of the two semi-circular sealing plates 2. The above structure makes the space inside the cover body 1 form a sealed space. In this way, when chemical gas leaks, gas overflow can be avoided as much as possible, forming a protective structure to prevent toxic chemical gas from polluting the environment and harming the human body.

[0027] It should be noted that the early warning monitoring device disclosed in the above embodiment is applied to the air pipe leakage early warning of chemical equipment and belongs to the field of chemical equipment monitoring and early warning equipment.

[0028] The implementation principle of a chemical equipment fault early warning device according to an embodiment of the present application is as follows: During use, personnel select a semi-circular sealing plate 2 with an adapted semi-circular groove 7 according to the diameter of the chemical gas delivery pipe to be monitored and warned. Then, the convex strip 6 of the semi-circular sealing plate 2 is snapped into the clamping groove 5 of the cover body 1. Then, the two cover bodies 1 are combined and the connecting plates 4 are locked together by bolts. At this time, the two semi-circular sealing plates 2 can be butt-jointed and combined together to seal the two ends of the cover body 1, so that the joint of the chemical gas delivery pipe is inside the cover body 1. In this way, when chemical gas leaks at the joint, the gas fills the cover body 1 at this time, so that the chemical gas detection sensor 3 can detect the chemical gas leakage and give an alarm in time to play a role of early warning.

[0029] Moreover, sealing gaskets are provided at the connection joints between the cover body 1, the semi-circular sealing plate 2 and the chemical gas pipe, so that the space inside the cover body 1 forms a sealed space. In this way, when chemical gas leaks, gas overflow can be avoided as much as possible, forming a protective structure to prevent toxic chemical gas from polluting the environment and harming the human body.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
