Description

Technical Field

[0001] This utility model relates to the technical field of gas sampling devices, and in particular to a gas sampling device for petrochemical refining. Background Technology

[0002] Oil refining is a process that distills crude oil or other oils without altering their molecular structure. During oil refining, crude oil must undergo a series of processing steps to obtain various useful petroleum products. Generally, it refers to the cracking of crude oil into fuels suitable for internal combustion engines, such as kerosene, gasoline, diesel, and heavy oil, and the production of chemical raw materials, such as alkenes and aromatics. Modern oil refineries are typically combined oil and chemical processes. These processes often generate large amounts of harmful gases. To ensure that emissions meet standards, these gases are collected and tested, thus requiring a gas sampling device for petrochemical refining.

[0003] According to the patent application CN219511910U, "This utility model discloses an environmentally friendly gas sampling device for chemical refining, comprising a mobile base and an electrical box. The electrical box is fixedly installed on the upper surface of the mobile base near the rear end, and a gas detection control console is fixedly installed on the upper surface of the mobile base near the other end. A gas processing tank is fixedly installed on the upper surface of the mobile base to one side of the gas detection control console. A transmission pulley is movably installed at the front end of the mobile base, and a winding frame is fixedly installed on the upper surface of the front end of the mobile base. A suction pipe is wound onto the surface of the winding frame, and a stepper motor is fixedly installed on the rear surface of the mobile base. This environmentally friendly gas sampling device for chemical refining eliminates the need to hold the suction pipe during prolonged sampling and allows the suction end of the suction pipe to be inserted into deeper and narrower spaces for gas sampling."

[0004] Regarding the above description, the applicant believes the following problems exist: During sampling, the end of the suction tube can be clamped at the extension rod clamp to avoid prolonged hand-holding. For deep and narrow spaces, the stepper motor is activated, driving the threaded shaft and the first bevel gear to rotate, causing the threaded sleeve block of the extension rod to move towards the front end of the sleeve. Simultaneously, the first bevel gear drives the second bevel gear, the drive shaft, and the drive pulley to rotate synchronously. The rotating drive pulley drives the driven pulley of the winding frame to rotate via a belt, releasing the suction tube on the winding frame, allowing the extension rod to continuously send the suction tube into the target space for sampling. However, this device has shortcomings; it cannot automatically organize the wound suction tube. Before each sampling, the operator needs to manually organize the tube, increasing the operation steps and time costs, reducing sampling efficiency, and increasing labor intensity.

A limit rod is fixedly connected to the inner side of the connecting plate, and a sliding block is slidably connected to the outside of the limit rod. A rotating block is rotatably connected to the inside of the sliding block. An air suction pipe is provided on the outside of the take-up roller.

[0007] Preferably, a groove is provided at the corresponding position of the reciprocating rod and the rotating block, and the rotating block is slidably connected inside the reciprocating rod.

[0008] Preferably, a through hole is provided at the corresponding position of the connecting plate and the reciprocating rod, and the reciprocating rod is rotatably connected inside the connecting plate.

[0013] The beneficial effects of this invention are as follows: A motor drives the take-up roller to rotate, which in turn moves the connecting belt outside the reciprocating rod.

This design achieves automatic arrangement and winding of the suction pipe, simplifies the operation steps, and effectively reduces the labor burden. Attached Figure Description

[0020] Please see Figures 1-4This utility model provides an embodiment of a gas sampling device for petrochemical refining, comprising a base plate 1; a support plate 21 and a fixing assembly; a gas detection control console 4 is fixedly connected to the top of the base plate 1; an electrical box 5 is fixedly connected to the end of the top of the base plate 1 near the gas detection control console 4; a gas processing tank 6 is fixedly connected to the end of the top of the base plate 1 away from the gas detection control console 4; a handle 7 is fixedly connected to the outside of the base plate 1; casters 8 are fixedly connected to the bottom of the base plate 1; a connecting pipe 9 is fixedly connected to the outside of the gas detection control console 4; and the support plate 21 is fixedly connected to the end of the top of the base plate 1 away from the gas detection control console 4. A motor 22 is fixedly connected to the outside of the support plate 21. A take-up roller 23 is fixedly connected to the output end of the motor 22. A connecting belt 25 is connected to the outside of the take-up roller 23. A reciprocating rod 210 is connected to the end of the connecting belt 25 away from the take-up roller 23. A spring 26 is fixedly connected to the top of the base plate 1 near the support plate 21. A support rod 211 is fixedly connected to the top of the base plate 1 near the spring 26. A top plate 27 is fixedly connected to the top of the spring 26. A connecting plate 28 is fixedly connected to the top of the top plate 27. A limit rod 29 is fixedly connected to the inner side of the connecting plate 28. A sliding block 21 is slidably connected to the outside of the limit rod 29. 2. A rotating block 213 is rotatably connected inside the sliding block 212. An air suction pipe 24 is provided outside the winding roller 23. When the air suction pipe 24 needs to be released or wound up, the winding roller 23 is driven to rotate by the motor 22, causing the winding roller 23 to drive the connecting belt 25 to rotate outside the reciprocating rod 210. At this time, the reciprocating rod 210 drives the sliding block 212 outside the rotating block 213 to continuously reciprocate outside the limiting rod 29, thereby pulling out the air suction pipe 24 neatly. At the same time, the spring 26 pushes the top plate 27 to slide outside the support rod 211, thereby keeping the air suction pipe 24 in a relatively taut state; the reciprocating rod 210 and the rotating block 213 A sliding groove is provided at the corresponding position, and the rotating block 213 is slidably connected to the inside of the reciprocating rod 210. Due to the reciprocating rod 210, the sliding block 212 outside the rotating block 213 can reciprocate outside the limiting rod 29. A through hole is provided at the corresponding position of the connecting plate 28 and the reciprocating rod 210, and the reciprocating rod 210 is rotatably connected to the inside of the connecting plate 28. Due to the connection plate 28, the rotation of the reciprocating rod 210 is stabilized. A through hole is provided at the corresponding position of the top plate 27 and the support rod 211, and the top plate 27 is slidably connected to the outside of the support rod 211. Due to the top plate 27, it is beneficial to provide an installation base for other components.

[0021] Please see Figure 4In this embodiment, the fixing component includes a placement block 31, which is fixedly connected to the top of the sliding block 212. A support rod 32 is fixedly connected to the top of the placement block 31, and a fixing plate 33 is fixedly connected to the top of the support rod 32. A second spring 34 is fixedly connected to the bottom of the fixing plate 33, and a pressure plate 35 is fixedly connected to the bottom of the second spring 34. A first rotating roller 36 is rotatably connected to the bottom of the pressure plate 35, a second rotating roller 37 is rotatably connected to the top of the placement block 31, and a push rod is fixedly connected to the top of the pressure plate 35. 38. Due to the spring 26, it is beneficial to cooperate with the rotating roller 37 to make the suction pipe 24 slide out quickly; the pressure plate 35 and the support rod 32 are provided with through holes at corresponding positions, and the pressure plate 35 is slidably connected to the outside of the support rod 32. Due to the support rod 32, it is convenient to slide the pressure plate 35; the fixed plate 33 and the push rod 38 are provided with through holes at corresponding positions, and the push rod 38 is slidably connected to the inside of the fixed plate 33. Due to the push rod 38, it is beneficial to pull the pressure plate 35 to slide outside the support rod 32.

[0022] When the suction pipe 24 needs to be released during operation, the suction pipe 24 is pulled, causing the second spring 34 to push the rotating roller 36 at the bottom of the pressure plate 35 to contact the suction pipe 24. The rotating roller 36 cooperates with the second rotating roller 37 to reduce the friction force of the suction pipe 24 sliding out. The motor 22 drives the take-up roller 23 to rotate, causing the take-up roller 23 to drive the connecting belt 25 to rotate outside the reciprocating rod 210. At this time, the reciprocating rod 210 drives the sliding block 212 outside the rotating block 213 to continuously reciprocate outside the limit rod 29, so that the suction pipe 24 is pulled out neatly. At the same time, the first spring 26 pushes the top plate 27 to slide outside the support rod 211, so that the suction pipe 24 is kept in a relatively taut state.

[0023] Through the above steps, the take-up roller 23 is driven to rotate by motor 22. The take-up roller 23 then drives the connecting belt 25 to move outside the reciprocating rod 210. As the connecting belt 25 moves, the reciprocating rod 210 causes the sliding block 212 outside the rotating block 213 to slide back and forth on the limiting rod 29. During this process, the suction pipe 24 is neatly pulled out. Simultaneously, the force of the spring 26 pushes the top plate 27 to slide outside the support rod 211, ensuring that the suction pipe 24 remains relatively taut. This design achieves automatic arrangement and winding of the suction pipe 24, simplifying the operation steps and effectively reducing the labor burden.
