Description

Technical Field

[0001] The present invention relates to the technical field of gas sensors, and in particular to a gas sensor capable of reducing oil fume pollution in an oil fume environment. Background Art

[0002] Gas sensors are devices that detect ambient gas components and convert them into electrical signals. They are widely used in fields such as oil fume monitoring and industrial safety. The complex composition of oil fume, grease particles, organic volatiles, and combustion products in oil fume environments places higher demands on sensor performance. Common types include semiconductor, infrared, and electrochemical sensors.

[0003] Gas sensors used in oil fume environments usually need to focus on preventing pollution and clogging: by installing oil filters or regularly cleaning the optical windows to reduce the adhesion of oil fume on the sensor surface. Oil fume usually contains grease particles, organic vapors (such as aldehydes and ketones) and combustion products (such as carbon monoxide and nitrogen oxides). These components will affect the performance and life of the sensor.

[0004] At present, when using gas sensors in an oil fume environment, a large amount of oil will quickly adhere to the oil filter, and the dust in the air will also be adsorbed on the oil filter, making the air flow inside the gas sensor poor, thereby affecting the sensitivity of the gas sensor. In the existing technology, most of them are achieved by frequently replacing or cleaning the oil filter. There are many disadvantages in this process. For example, when replacing the oil filter, it is easy for the oil fume to contaminate the gas sensor. When cleaning the oil filter, it is difficult to effectively clean the mesh of the oil filter. At the same time, the above methods are not timely, which will affect the sensitivity and accuracy of the sensor. In addition, when replacing and cleaning the oil filter, the gas sensor needs to be turned off, which affects the continuity of the detection data. In addition, improper restart operation may easily cause false alarms or erroneous data. Summary of the Invention

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0031] Example:

[0032] Reference Figures 1-6 , a gas sensor that can reduce oil fume pollution in an oil fume environment, includes a shell 1, and also includes: a fixing ring 3, fixedly connected to the inner wall of the shell 1, and a sensor probe 4 is fixedly connected to the fixing ring 3; a first oil filter 6, fixedly connected to the end of the shell 1, and a gas acceleration mechanism is provided between the first oil filter 6 and the sensor probe 4, for driving the gas to flow in the direction of the sensor probe 4; a circulation pipe 7, connected to the side wall of the shell 1, and a second oil filter 8 is fixedly connected to the end of the circulation pipe 7; a horizontal axis 13, rotatably connected between the shell 1 and the gas acceleration mechanism, and a first cleaning component is provided between the horizontal axis 13 and the circulation pipe 7, for cleaning the side of the second oil filter 8 away from the shell 1 Cleaning, a linkage assembly 14 is provided between the horizontal axis 13 and the gas acceleration mechanism, which is used to drive the horizontal axis 13 to rotate in different directions according to the rotation direction of the gas acceleration mechanism, wherein a second cleaning assembly is provided between the horizontal axis 13 and the first oil filter 6, which is used to clean the side of the first oil filter 8 away from the outer shell 1; a mesh cleaning mechanism is provided between the outer shell 1 and the second oil filter 8 and between the gas acceleration mechanism and the first oil filter 6, which is used to clean the meshes of the first oil filter 6 and the second oil filter 6, a threaded column 2 is fixedly connected to the outer shell 1, and the threaded column 2 is hollow, a connecting line 5 is fixedly connected to the sensor probe 4, and the connecting line 5 passes through the inside of the outer shell 1 to the hollow part of the threaded column 2.

[0033] In this embodiment, by adjusting the rotation direction of the gas acceleration mechanism, the flow direction of the gas in the outer shell 1 can be adjusted, so that the first oil filter 6 or the second oil filter 8 can be cleaned by driving the first cleaning component or the second cleaning component, and then the mesh cleaning mechanism is driven to deeply clean the mesh of the first oil filter 6 or the second oil filter 8. In this process, not only the stability of the gas flow can be guaranteed, but also the oil in the mesh can be prevented from entering the outer shell 1, thereby ensuring the continuity of the gas sensor detection, and at the same time improving the sensitivity and accuracy of the sensor probe 4.

[0034] Reference Figure 3 and Figure 4The gas acceleration mechanism includes a mounting base 9 fixedly connected to the inner wall of the outer shell 1, and a driving motor 10 is fixedly connected to the side of the mounting base 9 close to the first oil filter 6. The side of the mounting base 9 close to the sensor probe 4 is rotatably connected to an intake fan 11 connected to the drive motor 10, and a driving bevel gear 12 is fixedly connected to the shaft of the intake fan 11, wherein the mounting base 9 is located between the first oil filter 6 and the sensor probe 4. When the drive motor 10 rotates forward, the external gas flows from the first oil filter 6 to the outer shell 1, and then flows to the outside through the second oil filter 8. When the drive motor 10 rotates reversely, the external gas flows from the second oil filter 8 to the outer shell 1, and then flows to the outside through the first oil filter 6.

[0035] In this embodiment, when the driving motor 10 drives the air intake fan 11 to rotate, the flow direction of the gas can be adjusted according to the rotation direction of the air intake fan 11, while increasing the speed of the gas flow, improving the response speed of the sensor detection, ensuring the accuracy of the detection, and reducing the deposition of oil on the sensor surface, thereby extending the service life of the sensor.

[0036] Reference Figure 1 and Figure 4 The first cleaning component includes a first reciprocating screw 15 and a limit rod 17 rotatably connected between the circulation pipe 7 and the outer shell 1 in a symmetrical position, and a first slider 16 is slidably connected to the first reciprocating screw 15 and the limit rod 17, wherein a first bevel gear set 21 that meshes with each other is provided between the first reciprocating screw 15 and the horizontal shaft 13, and a protrusion matching the first reciprocating screw 15 is provided inside the first slider 16 near the first reciprocating screw 15, and a connecting ring 18 is fixedly connected between the two groups of first sliders 16, and a first cleaning member 19 that fits the second oil filter 8 is fixedly connected to the first slider 16 and the connecting ring 18, and the first cleaning member 19 is arranged at an angle.

[0037] In this embodiment, when the gas flows into the housing 1 from the first oil filter 6 and is discharged from the second oil filter 8, the bevel gear 12 is driven to drive the horizontal shaft 13 close to the side of the first bevel gear set 21 to rotate. At this time, under the action of the first reciprocating screw 15, the first cleaning member 19 is driven to move back and forth along the surface of the second oil filter 8, thereby cleaning the second oil filter 8. Since the gas in the housing 1 is discharged from the second oil filter 8 at this time, the oil stains in the mesh of the second oil filter 8 can be avoided from being blocked by the movement of the first cleaning member 19. When the gas flows in the opposite direction, the first cleaning member 19 stops moving, thereby ensuring the stability of the gas flow.

[0038] Reference Figure 2-Figure 4The second cleaning assembly includes a second reciprocating screw 22 rotatably connected to the outer wall of the shell 1 on the side away from the first bevel gear set 21, a second bevel gear set 23 that meshes with each other is provided between the second reciprocating screw 22 and the horizontal shaft 13, a second slider 24 is provided on the second reciprocating screw 22, and the end of the second reciprocating screw 22 away from the second bevel gear set 23 is fixedly connected to the driving wheel 26, the first oil filter 6 is rotatably connected to the rotating shaft 27, the rotating shaft 27 is fixedly connected to the driven wheel 28, a belt 29 is sleeved between the driven wheel 28 and the driving wheel 26, and the rotating shaft 27 is fixedly connected to the second cleaning member 30 that fits the first oil filter 6, wherein the second cleaning member 30 is located between the belt 29 and the first oil filter 6, the rotating shaft 27 is located at the center of the first oil filter 6, and the size of the second cleaning member 30 matches the size of the first oil filter 6.

[0039] In this embodiment, when the gas enters the housing 1 through the second oil filter 8 and is discharged through the first oil filter 6, the driving bevel gear 12 drives the horizontal shaft 13 close to the side of the second bevel gear set 23 to rotate, thereby driving the second reciprocating screw 22 to rotate, and drives the second cleaning member 30 to rotate along the first oil filter 6 through the driving wheel 26, the driven wheel 28 and the belt 29 to clean the oil stains on the surface of the first oil filter 6. At the same time, this method can always maintain the cleanliness of the first oil filter 6 and the second oil filter 8, thereby ensuring the stability of the gas flow, while reducing the disassembly frequency of the first oil filter 6 and the second oil filter 8, improving the continuity and stability of gas detection, and extending the service life of the first oil filter 6 and the second oil filter 8.

[0040] Reference Figure 3-Figure 5 The linkage assembly 14 includes a driven bevel gear 141 and a center disk 142 rotatably connected to the driven bevel gear 141. The center disk 142 is connected to the horizontal shaft 13. A cavity 143 is opened between the driven bevel gear 141 and the center disk 142. The side of the driven bevel gear 141 near the cavity 143 is fixedly connected with multiple groups of ratchet teeth 144 in an annular array. The side of the center disk 142 near the ratchet teeth 144 is rotatably connected with multiple groups of rotating rods 145. An elastic member 146 is fixedly connected between the rotating rod 145 and the center disk 142. When the drive motor 10 rotates forward, the rotating rod 145 near the side of the first bevel gear set 21 meshes with the ratchet teeth 144, and the ratchet teeth 144 on the other side rotate along the end of the rotating rod 145. When the drive motor 10 rotates reversely, the rotating rod 145 near the side of the second bevel gear set 23 meshes with the ratchet teeth 144, and the ratchet teeth 144 on the other side rotates along the end of the rotating rod 145.

[0041] In this embodiment, when the driving bevel gear 12 rotates, the driven bevel gear 141 is driven to rotate. During this process, the ratchet 144 in the driven bevel gear 141 on one side engages with the rotating rod 145, and the ratchet 144 in the driven bevel gear 141 on the other side rotates along the outside of the rotating rod 145. That is to say, at this time, the horizontal axis 13 on one side rotates, and the horizontal axis 13 on the other side is in a stopped state, so that the first oil filter 6 or the second oil filter 8 at the exhaust position can be cleaned according to the oil pollution condition on the surface of the first oil filter 6 and the second oil filter 8. At the same time, the clogging of the mesh of the first oil filter 6 or the second oil filter 8 can be avoided.

A driving disk 36 is fixedly connected to the end portion, and a plurality of second cleaning heads 37 are fixedly connected to the side of the driving disk 36 away from the second telescopic rod 35, wherein the size of the driving disk 36 is smaller than the size of the circulation pipe 7, and the second cleaning head 37 matches the mesh of the second oil filter 8. It also includes a first hydraulic rod 20 fixedly connected between the first slider 16 and the circulation pipe 7, and the first hydraulic rod 20 is connected to the first telescopic rod 31 through a pipeline. It also includes a second hydraulic rod 25 fixedly connected between the second slider 24 and the outer wall of the outer shell 1, and the second hydraulic rod 25 is connected to the second telescopic rod 35 through a pipeline.
