Description

Technical Field

[0001] This utility model belongs to the field of gas leak detection technology, specifically relating to a device for detecting gas leaks in chemical processes. Background Technology

[0002] Chemical process gas leak detection devices are used to monitor gas leaks in real time during production. Common detection methods include infrared sensors, catalytic combustion sensors, and electrochemical sensors. The device captures changes in gas concentration through sensors and transmits the data to the monitoring system so that leaks can be detected and measures can be taken in a timely manner.

[0003] Chinese patent publication number CN221611167U discloses a device for detecting leaks of chemical process gases. The device includes a detection shell with a cover fitted to its top and a vent at its bottom. A folding cylinder is fixedly connected to the outer side of the bottom of the detection shell corresponding to the vent. A rubber cover communicating with the folding cylinder is fixedly connected to its bottom. An annular support plate is fixedly connected to the inner wall of the detection shell, and a test strip is mounted on the top of the annular support plate. Pressure rods are symmetrically installed on the top of the inner wall of the cover, and a pressure block is fixedly connected to the bottom of each pressure rod. The bottom of the pressure block contacts the top of the test strip. This device for detecting leaks of chemical process gases has a reasonable structural design, is easy to use, and can be adapted to leak detection of different gases and equipment. It has a good range of applications and practicality, low manufacturing cost, and good performance, fully meeting the needs of users.

[0004] However, the current detection device has the following problems: In winter conditions, the gas flow rate is relatively slow, which will cause the gas leak detection to take a long time to confirm the existence of the gas leak. The delayed detection of gas leaks seriously affects the speed and effectiveness of emergency response. Therefore, we propose a device for detecting gas leaks in chemical processes. Utility Model Content

[0005] The purpose of this invention is to provide a device for detecting gas leaks in chemical processes. This device addresses the problem in related technologies where, under winter conditions, the gas flow rate is inherently slow, leading to a prolonged time required to confirm the existence of a gas leak. This delayed detection of gas leaks severely impacts the speed and effectiveness of emergency response.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A device for detecting leaks of chemical process gases includes a detection housing. A housing cover is bolted to the side of the detection housing. An annular support plate is fixedly connected to the inner wall of the detection housing. A test strip is placed on the top of the annular support plate. Two connecting rods are fixedly connected to the inner wall of the housing cover. A pressure block is fixedly connected to the bottom of each of the two connecting rods. A handle is fixedly connected to the top of the housing cover. A vent is provided at the bottom of the detection housing. A fanning device for accelerating the flow rate is provided on the side of the detection housing. The fanning device includes a motor. The side of the motor is fixedly connected to the side of the detection housing. A track column is fixedly connected to the output shaft of the motor. A slide rail is fixedly connected to the inner wall of the detection housing. A track rod is slidably connected to the inner wall of the slide rail. A T-shaped rod is fixedly connected to the top of the track rod. Several swing rods are fixedly connected to the side of the T-shaped rod.

[0008] The fanning device also includes a fixed rod that is fixedly connected to the inner wall of the detection shell, and fanning blades are rotatably connected to the circumferential surfaces of several fixed rods.

[0009] The end of the track rod away from the slide rail is spherical, and the spherical end of the track rod is in contact with the inner wall of the track column. Several swing rods are in contact with several fan-shaped plates.

[0010] The top of the T-shaped rod is equipped with a dehumidification device, which includes an L-shaped rod. The bottom of the L-shaped rod is fixedly connected to the top of the T-shaped rod. Several squeezing rods are fixedly connected through the side of the L-shaped rod. Two dehumidification blocks are fixedly connected to the inner wall of the detection shell, and two collection grooves are fixedly connected to the inner wall of the detection shell.

[0011] The dehumidifying block is located on the movement trajectory of the extrusion rod, and the collection trough is located below the dehumidifying block.

[0012] A gap is provided between the T-shaped rod and the detection shell, and the test paper is located on the movement trajectory of the pressure block.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This invention utilizes a fan-driven device to coordinate the track column, slide rail, track rod, T-shaped rod, swing rod, fixed rod, and fan-driven plate. The left and right movement of the T-shaped rod drives the left and right movement of the swing rod, which in turn drives the left and right movement of the fan-driven plate. The left and right movement of the fan-driven plate can accelerate the gas flow rate, preventing the detection device from taking too long to determine the gas leak and affecting the speed of emergency response.

[0015] This invention utilizes a dehumidification device that coordinates the L-shaped rod, the squeezing rod, the dehumidifying block, and the collection tank. When the cover 2 is closed, the dehumidifying block absorbs moisture from the air, preventing it from contacting the test strip and causing it to become damp, thus affecting the test results. Simultaneously, the left-right movement of the T-shaped rod causes the L-shaped rod to move left-right, which in turn causes the squeezing rod to move left-right. This squeezing action compresses the dehumidifying block, drawing moisture into the collection tank. This prevents the dehumidifying block from becoming saturated after prolonged use, reducing its dehumidification capacity and causing the test strip to become damp. Furthermore, this design improves the effectiveness of the dehumidifying block. Attached Figure Description

Detailed Implementation

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figure 1 - Figure 5As shown, a device for detecting leaks of chemical process gases includes a detection housing 1. A housing cover 2 is bolted to the side of the detection housing 1. An annular support plate 3 is fixedly connected to the inner wall of the detection housing 1. A test strip 4 is placed on the top of the annular support plate 3. Two connecting rods 5 are fixedly connected to the inner wall of the housing cover 2. A pressure block 6 is fixedly connected to the bottom of each connecting rod 5. A handle 7 is fixedly connected to the top of the housing cover 2. A vent 10 is provided at the bottom of the detection housing 1 to facilitate gas passage for detection. A fanning device 8 for accelerating the flow rate is provided on the side of the detection housing 1. The fanning device 8 includes a motor 81, which is fixedly connected to the side of the detection housing 1. The motor 81 outputs... The output shaft is fixedly connected to a track column 82, the inner wall of the detection housing 1 is fixedly connected to a slide rail 83, the inner wall of the slide rail 83 is slidably connected to a track rod 84, the top of the track rod 84 is fixedly connected to a T-shaped rod 85, the side of the T-shaped rod 85 is fixedly connected to several swing rods 86, the fanning device 8 also includes a fixed rod 87 fixedly connected to the inner wall of the detection housing 1, and fanning plates 88 are rotatably connected to the circumferential surface of several fixed rods 87. The end of the track rod 84 away from the slide rail 83 is spherical. The spherical design can move better in the slot than other shapes, and the spherical end of the track rod 84 contacts the inner wall of the track column 82. Several swing rods 86 contact several fanning plates 88.

[0025] Based on the above structure, the detection shell 1 is placed in a location where leakage may occur. After placing the test paper 4, the shell cover 2 is closed, and the motor 81 is started. The output shaft of the motor 81 rotates, causing the track column 82 to rotate. The rotation of the track column 82 causes the track rod 84 to move left and right along the interior of the track column 82. The left and right movement of the track column 82 causes the T-shaped rod 85 to move left and right. The left and right movement of the T-shaped rod 85 causes the swing rod 86 to move left and right. The left and right movement of the swing rod 86 causes the fan-shaped plate 88 to move left and right. The left and right movement of the fan-shaped plate 88 can accelerate the gas flow rate, avoiding the detection device needing a long time to determine the gas leak, which would affect the speed of emergency response.

[0026] like Figure 1 - Figure 5As shown, a dehumidification device 9 is provided at the top of the T-shaped rod 85. The dehumidification device 9 includes an L-shaped rod 91. The bottom of the L-shaped rod 91 is fixedly connected to the top of the T-shaped rod 85. Several squeezing rods 92 are fixedly connected through the side of the L-shaped rod 91. Two dehumidification blocks 93 are fixedly connected to the inner wall of the detection shell 1. Two collection grooves 94 are fixedly connected to the inner wall of the detection shell 1. The dehumidification blocks 93 are located on the movement trajectory of the squeezing rods 92. The collection grooves 94 are located below the dehumidification blocks 93. The water droplets absorbed by the dehumidification blocks 93 can flow into the collection grooves 94 to prevent the squeezed water from directly contacting the test paper 4. There is a gap between the T-shaped rod 85 and the detection shell 1. This setting can prevent the T-shaped rod 85 from hitting the detection shell 1 during left and right movement, causing damage to the parts. The test paper 4 is located on the movement trajectory of the pressure block 6.

[0027] According to the above structure, when the cover 2 is closed, due to the high humidity in the air during winter, the dehumidifying block 93 will absorb the moisture in the air, preventing the moisture in the air from contacting the test paper 4 and causing the test paper 4 to become damp, thus affecting the test results of the test paper 4; at the same time, the left and right movement of the T-shaped rod 85 drives the left and right movement of the L-shaped rod 91, which in turn drives the left and right movement of the squeezing rod 92. The left and right movement of the squeezing rod 92 will squeeze the dehumidifying block 93, causing the moisture in the dehumidifying block 93 to flow into the collection tank 94 through squeezing, preventing the dehumidifying block 93 from becoming saturated after long-term absorption, reducing its dehumidification capacity and causing the test paper 4 to become damp; it can also improve the use effect of the dehumidifying block 93.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
