Description

Technical Field

[0001] The utility model relates to the technical field of gas monitoring, in particular to an exhaust gas monitoring device. Background Art

[0002] Due to a large amount of dust generated during the production process, the cement industry is listed as a highly polluting industry. Therefore, continuous monitoring of exhaust gas is required in the space of cement processing.

[0003] The gas monitoring equipment in cement production often needs to adapt to the actual situation at different stages or positions. However, most of the existing gas monitoring devices are fixedly installed in a certain place. During use, the gas monitoring equipment cannot be adjusted in position, resulting in its inability to adapt to the changes in the production line, inaccurate monitoring data, and limitations. For this reason, we propose an exhaust gas monitoring device to solve the existing problems. Content of the Utility Model

[0004] The purpose of the utility model is to propose an exhaust gas monitoring device for the problems existing in the background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An exhaust gas monitoring device includes a lifting rod, an outer sleeve, a gas tank, a mounting frame, and a gas monitor. Inside the mounting frame, there are a gas tank and a pressure pump. At the upper end of the mounting frame, there are an outer sleeve and a gas monitor. A hose is arranged at the suction end of the gas monitor, and a suction nozzle is arranged at one end of the hose. Inside the outer sleeve, there are an inner sleeve and a lifting rod sleeved and installed. Universal wheels are arranged at the four corners of the lower end of the mounting frame. A pressurizing pipe is connected and installed between the gas tank and the pressure pump, and a connecting pipe passing through the outer sleeve is arranged at the output end of the gas tank.

[0006] Preferably, the mounting frame is in the shape of a flat U-shaped groove, and both the gas tank and the pressure pump are located inside the U-shaped groove. A pair of symmetrically distributed handles are arranged at one end of the mounting frame. The groove structure inside the U-shaped groove mounting frame can be used for the installation and storage of the gas tank and the pressure pump, facilitating the installation of the equipment. When moving the equipment, it is convenient to apply pushing and pulling forces by grasping the handles.

[0007] Preferably, a control component is arranged inside the connecting pipe, and the control component includes a pressure gauge and a pressure relief valve. The control component inside the connecting pipe facilitates understanding the pressure situation inside the gas tank and relieving the pressure inside the outer sleeve through the pressure relief valve.

[0008] Preferably, a check valve is arranged inside the pressurizing pipe. The check valve enables the pressure medium to flow only unidirectionally into the gas tank when the pressurizing pipe conveys the pressure medium, preventing the high pressure inside the gas tank from flowing back through the pressurizing pipe.

[0009] Preferably, the hose is connected to the lifting rod, and a filter screen is arranged inside the suction nozzle. One end of the hose follows the lifting rod to adjust the height. When the suction nozzle sucks gas, the filter screen intercepts dust in the environment to prevent the dust from entering the hose.

[0010] Preferably, a first sliding sleeve through which the inner sleeve slides is embedded in the inner wall of the upper end of the outer sleeve, and a second sliding sleeve through which the lifting rod slides is embedded in the inner wall of the upper end of the inner sleeve. The lifting rod is longitudinally slidably guided inside the inner sleeve through the second sliding sleeve, and the inner sleeve is longitudinally slidably guided inside the outer sleeve through the first sliding sleeve.

[0011] Preferably, limiting blocks are arranged at the lower ends of both the inner sleeve and the lifting rod. The outer diameter of the limiting block at the lower end of the lifting rod is larger than the inner diameter of the second sliding sleeve, and the outer diameter of the limiting block at the lower end of the inner sleeve is larger than the inner diameter of the first sliding sleeve. The lower end of the lifting rod is prevented from completely disengaging from the second sliding sleeve through the limiting block, and the inner sleeve is prevented from completely disengaging from the first sliding sleeve through the limiting block.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. In the present utility model, the suction nozzle of the gas monitoring device is installed on the lifting rod. The lifting rod is slidably installed inside the inner sleeve, and the inner sleeve is slidably installed inside the outer sleeve. Under the adjustment of the internal air pressure, the inner sleeve and the lifting rod can move longitudinally, thereby adjusting the horizontal position of the suction nozzle. Combined with the universal wheels at the bottom, the device is convenient to move, can flexibly meet the needs of waste gas monitoring, and can be effectively adjusted, making it convenient to use.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1-4 shown, an exhaust gas monitoring device proposed by the present invention includes a lifting rod 2, an outer sleeve 4, a gas tank 7, a mounting rack 8, and a gas monitor 12. A gas tank 7 and a pressure pump 10 are arranged inside the mounting rack 8. An outer sleeve 4 and a gas monitor 12 are arranged at the upper end of the mounting rack 8. A hose 3 is arranged at the suction end of the gas monitor 12, and a suction nozzle 1 is arranged at one end of the hose 3.

[0021] The mounting rack 8 is in the shape of a horizontally placed U-shaped groove, and both the gas tank 7 and the pressure pump 10 are located inside the U-shaped groove. A pair of symmetrically distributed handles 13 are arranged at one end of the mounting rack 8.

[0022] The hose 3 is connected to the lifting rod 2, and a filter screen 14 is arranged inside the suction nozzle 1.

[0023] Based on the implementation steps of Embodiment 1: The gas monitor 12 sucks gas through the hose 3. When passing through the suction nozzle 1, the suction force acts on the outside, sucking the gas in the surrounding environment. The dust in the exhaust gas is intercepted by the filter screen 14, and the exhaust gas is detected by the gas monitor 12 to understand the pollution situation of the exhaust gas, and the production is adjusted according to the detection situation.

[0024] As Figures 1-4 shown, compared with Embodiment 1, an exhaust gas monitoring device proposed by the present invention further includes: an inner sleeve 17 and a lifting rod 2 are sleeved and installed inside the outer sleeve 4. Universal wheels 9 are arranged at the four corners of the lower end of the mounting rack 8. A pressurizing pipe 11 is connected between the gas tank 7 and the pressure pump 10. A connecting pipe 5 penetrating through the outer sleeve 4 is arranged at the output end of the gas tank 7. A control assembly 6 is arranged inside the connecting pipe 5, and the control assembly 6 includes a pressure gauge and a pressure relief valve;

[0025] A one-way valve 19 is arranged inside the pressurizing pipe 11;

[0026] A sliding sleeve one 16 through which the inner sleeve 17 slides is embedded and installed on the inner wall of the upper end of the outer sleeve 4, and a sliding sleeve two 18 through which the lifting rod 2 slides is embedded and installed on the inner wall of the upper end of the inner sleeve 17;

[0027] Limit blocks 15 are arranged at the lower ends of both the inner sleeve 17 and the lifting rod 2. The outer diameter of the limit block 15 at the lower end of the lifting rod 2 is larger than the inner diameter of the sliding sleeve two 18, and the outer diameter of the limit block 15 at the lower end of the inner sleeve 17 is larger than the inner diameter of the sliding sleeve one 16.

[0028] In this embodiment, the pressure pump 10 conveys pressurized gas into the inside of the gas tank 7. The gas tank 7 stores pressurized gas. When it is necessary to adjust the detection position of the gas monitor 12, the gas tank 7 conveys the pressurized gas into the inside of the outer sleeve 4 through the connecting pipe 5. The pressure acts on the inner sleeve 17 and the lifting rod 2, so that the lifting rod 2 longitudinally slides inside the inner sleeve 17 through the second sliding sleeve 18;

[0029] It is worth noting that in order to solve the problem of limited height, the inner sleeve 17 longitudinally slides inside the outer sleeve 4 through the first sliding sleeve 16, and the socket part is set by itself according to needs. It has a socket structure and a lifting structure controlled by pressure, occupying less space. The horizontal position of the suction nozzle 1 can be adjusted. During the process of waste gas monitoring, it adapts to the detection needs of different requirements. When the position of the suction nozzle 1 is adjusted through the universal wheel 9, it is convenient for the movement of the device, adapts to the changes in the production line, the detection data is more accurate, and it avoids the problem that the detection data has limitations for the detection of a single position. During the process of gas monitoring, the suction nozzle 1 can be adjusted to different positions to suck and detect gases at different horizontal heights, providing reference value for the monitoring data.
