Description

Technical Field

[0001] The utility model relates to the technical field of gas equipment detection, in particular to a gas filter sealing detection device. Background Art

[0002] Gas filters are widely used in metallurgy, chemical industry, petroleum, papermaking, medicine, food, mining, electricity, cities, households and other gas-using fields. Gas filters are an indispensable device on the pipeline for conveying medium. They are usually installed at the inlet end of pressure reducing valves, pressure relief valves, positioning valves or other equipment to eliminate impurities in the medium, protect the normal use of valves and equipment, and reduce equipment maintenance costs.

[0003] The gas filter is a gas equipment with high safety requirements. Usually, the various pipes of the gas filter are connected by welding. In order to detect the quality of the welds and ensure that the gas filter can withstand greater pressure, air tightness testing is required during the production process. The existing testing equipment cannot achieve rapid clamping of the gas filter. The air tightness test requires the gas filter to be immersed in liquid to observe whether bubbles are generated or leaks occur. After the test is completed, the surface of the gas filter is moist. Direct removal will not only easily cause pollution to the working area, but also easily lead to rust on the filter surface. Utility Model Content

[0014] The beneficial effects of the utility model are:

[0015] The gas filter sealing detection device seals and clamps the gas filter, immerses it in liquid, and transmits airflow to the inside to maintain a certain air pressure inside. By observing whether bubbles are generated, it is judged whether gas leakage can be avoided within a certain air pressure. After the detection is completed, the mobile air drying equipment can dry the surface of the gas filter to avoid surface corrosion caused by excessive water stains. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0021] like Figure 1-3 A gas filter sealing detection device shown in the figure comprises a soaking box 1, a mounting seat 2, a first oil cylinder 3, a clamping assembly 4, a guide rail 5 and an air drying device 6, wherein the mounting seat 2 is fixedly arranged on the outside of one end of the soaking box 1, the first oil cylinder 3 is installed on the outside of the mounting seat 2, the clamping assembly 4 is fixedly arranged on the telescopic end of the first oil cylinder 3, the guide rail 5 is fixedly arranged on both sides of the soaking box 1, the air drying device 6 is clamped on the inner side of the top of the guide rail 5, and the clamping assembly 4 comprises a lifting seat 41, a guide seat 42, a clamping seat 43, The second oil cylinder 44, the fixed plug 45, the air pump pipe 46 and the movable plug 47, the lifting seat 41 is fixedly arranged at the telescopic end of the first oil cylinder 3, the guide seat 42 is fixedly arranged at one end of the top of the lifting seat 41, the clamping seat 43 is clamped in the guide seat 42, the second oil cylinder 44 is fixedly arranged inside one side of the lifting seat 41, the fixed plug 45 is fixedly arranged at the outer bottom end of the lifting seat 41, the air pump pipe 46 is installed at the tail of the fixed plug 45, and the movable plug 47 is fixedly arranged at the inner bottom of the clamping seat 43.

[0022] Specifically, the air drying equipment 6 includes a support plate 61, an air guide cover 62 and an air intake pipe 63. The support plate 61 is clamped on the inner side of the top of the guide rail 5, the air guide cover 62 is fixedly arranged on the inner side of the top of the support plate 61, and the air intake pipe 63 is fixedly arranged on the outer side of the support plate 61 and is located at the rear of the air guide cover 62. A guide block is fixedly arranged at the bottom of the support plate 61, and a guide groove matching with it is opened at the top of the guide rail 5. An air guide strip inclined downward is laterally fixed to the inner side of the air guide cover 62. The movable plug 47 is concentrically arranged with the fixed plug 45, and the ends of the movable plug 47 and the fixed plug 45 are conical structures. An air intake hole is opened in the middle of the fixed plug 45. The telescopic end of the second oil cylinder 44 is fixed to the inner side of the clamping seat 43, and a connecting rod connected to the telescopic end of the second oil cylinder 44 is fixedly arranged on the inner side of the clamping seat 43.

[0023] In this embodiment, the first oil cylinder 3 and the second oil cylinder 44 are both in an extended state. After aligning the two ends of the gas filter with the fixed plug 45 and the movable plug 47 respectively, the second oil cylinder 44 contracts, thereby causing the clamping seat 43 to move backward and contract, and the movable plug 47 to move backward. The ends of the fixed plug 45 and the movable plug 47 are both conical structures, which are convenient for inserting into the interior of the two ends of the gas filter and effectively sealing. A guide adjustment card is provided on one side of the top of the clamping seat 43 and is arranged in the guide seat 42 to support and ensure that the clamping seat 43 runs horizontally. After the clamping is completed, the first oil cylinder 3 contracts to immerse the gas filter in the liquid inside the immersion box 1, and inflate the interior of the gas filter through the air pump and the air pump pipe 46 to generate high pressure inside the gas filter. Observe whether bubbles are generated at the connection position when the gas filter is in the internal high-pressure state. If no leakage occurs in the high-pressure state for a period of time, it means that the use needs are met.

[0024] Furthermore, the first oil cylinder 3 extends out to take the clamped gas filter away from the immersion box 1, and pushes the support plate 61 in the guide rail 5 to move the air guide cover 62 to both sides of the gas filter. Then the blower starts, and the high-speed airflow enters the air inlet pipe 63 through the connecting pipe. Then, under the action of the air guide cover 62 and the air guide strips inclined downward inside it, the high-speed airflow acts on the surface of the gas filter at an angle downward to blow off the water stains remaining on the surface, thereby facilitating the removal of the workpiece and reducing the risk of rust on the workpiece surface.
