Description

Technical Field

[0001] The utility model belongs to the technical field of gas detection devices, and in particular relates to a gas detection device for safe production in chemical industry. Background Art

[0002] During the entire production operation process in the chemical workshop, the production is confined to a workshop with limited space. Some toxic and harmful gases and fine dust particles will be generated during the production process and float in the chemical workshop. The ventilation capacity of the entire chemical workshop is limited, so the monitoring and detection of harmful gases are very important. In the existing technology, the gas safety detection device is set in a fixed area in the chemical workshop to detect the concentration of harmful gases in the chemical workshop. The gas detection device collects and analyzes harmful gases in the air through sensors. The sensor is an important component for analyzing harmful gases and has high sensitivity. However, the sensor is in the closed environment of the chemical workshop for a long time and is easily blocked by dust particles in the chemical workshop, resulting in false alarms or missed alarms of the detection device, which may seriously cause safety accidents.

The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0024] Example 1: Reference Figure 1-Figure 7 A chemical production safety gas detection device includes: a detection box body 1 equipped with an exhaust fan 11, which is used to draw gas outside the detection box body 1 into the detection box body 1; a fixed cover 12, which is connected to the detection box body 1 at the exhaust fan 11, the exhaust fan 11 is located in the fixed cover 12, and a barrel cover 13 is fixedly connected to the fixed cover 12; an installation cover 2, one end of which is inserted into the barrel cover 13, and a first filter screen 24 and a second filter screen 26 are respectively installed on the installation cover 2, and the installation cover 2 is fixedly connected to the first filter screen 24 with a collection box 27, which is used to collect foreign matter dropped from the first filter screen 24; a motor 33, which is installed on the barrel cover 13, and a protrusion 34 is installed on the output end of the motor 33, which is used to move the installation cover 2 to drop foreign matter on the first filter screen 24;

[0025] The mounting cover 2 includes an inserting tube 23, a flanged cover 21, and a connecting tube 25. The flanged cover 21 is flanged outward from one end of the inserting tube 23. A first filter 24 is fixedly connected to the inserting tube 23. A second filter 26 is mounted on the connecting tube 25. The connecting tube 25 is threadedly connected to the end of the inserting tube 23 away from the flanged cover 21. A collection box 27 is fixedly connected to the inserting tube 23. A slot 131 is formed on the tube cover 13, and the collection box 27 slides in the slot 131.

[0026] A plurality of buckles 22 are fixedly connected to the circumference of the inner wall of the flange cover 21, and a fixing ring 132 is fixedly connected to the outer circumference of the end of the barrel cover 13 away from the fixed cover 12, and the buckles 22 correspond to the fixing ring 132;

[0027] A plurality of springs 133 are fixedly connected to the circumference of the fixing ring 132 , and the springs 133 correspond to the front wall of the flange cover 21 ;

[0028] When the device is in use, the connecting tube 25 is rotatably connected to one end of the inserting tube 23, and then the connecting tube 25 and the inserting tube 23 are inserted into the tube cover 13 together, and the flanged cover 21 is pushed so that the flanged cover 21 is pressed against the spring 133, and the buckle 22 is clamped on the fixing ring 132, so that the mounting cover 2 is stably installed in the tube cover 13;

[0029] When the detection box body 1 is in use, the exhaust fan 11 draws gas into the detection box body 1 for gas detection, and the first filter 24 provided on the mounting cover 2 can block dust and collect it through the collection box 27 provided below;

[0030] The motor 33 is activated at a set time interval, driving the protrusion 34 to push the flange cover 21 on the installation cover 2, causing the installation cover 2 to slide into the barrel cover 13 and compress the spring 133. When the protrusion 34 moves away from the installation cover 2, the installation cover 2 rebounds, causing the dust on the first filter 24 to fall further into the collection box 27.

[0031] The second filter 26 can further filter the dust in the gas, further improving the detection of the gas by the detection box body 1;

[0032] After using for a period of time, the first filter 24 and the second filter 26 can be quickly cleaned by pulling the mounting cover 2 out of the barrel cover 13, which is very convenient to use.

[0033] Therefore, compared with the existing technology, this device, announcement number: CN221445770U, named as an existing technology of a gas detection device for chemical production safety, can not only effectively filter the dust in the gas, but also quickly clean the first filter 24 and the second filter 26, and through the set motor 33, it can further facilitate the cleaning of the first filter 24 and the second filter 26 in use, further improving the filtering effect.

[0035] The height of the motor 33 can be adjusted by rotating the threaded rod 35 , thereby facilitating the insertion of the mounting cover 2 into the barrel cover 13 .

[0036] Example 3: Reference Figure 3 , a chemical production safety gas detection device, which is basically the same as Example 2, further comprising: the buckle 22 and the spring 133 are respectively set to 6;

[0037] This ensures that the mounting cover 2 is evenly stressed and the connection is more stable.

[0038] The connecting plate 32 is located on both sides of the slide groove 31 and is fixedly connected to the limiting blocks 36 for limiting the connecting plate 32 in the slide groove 31 to prevent the connecting plate 32 from shaking on the mounting frame 3.

[0039] The present invention can not only effectively filter the dust in the gas, but also quickly remove the first filter 24 and the second filter 26 from the barrel cover 13 for cleaning. Moreover, through the provided motor 33, it can further facilitate the cleaning of the first filter 24 and the second filter 26 in use, thereby further improving the filtering effect.
