Description

Technical Field

[0001] This utility model belongs to the field of chemical raw material extraction technology, and in particular relates to a chemical raw material sampling and extraction device. Background Technology

[0002] A chemical raw material sampling and extraction device is a specialized piece of equipment used to automatically or semi-automatically collect representative samples from raw materials such as liquids, solid particles, and gases during chemical production, storage, or transportation, according to scientific sampling standards and specifications. Its core function is to avoid the errors and safety risks that may exist in manual sampling, such as contact with toxic and harmful raw materials, by precisely controlling the sampling quantity, sampling location, and sampling frequency. At the same time, it ensures that the extracted samples can accurately reflect the key indicators such as the composition, purity, and impurity content of the overall raw materials, providing a reliable basis for subsequent quality testing, component analysis, compliance verification, such as compliance with industry standards or safe production requirements, and production process adjustments.

[0003] However, in the use of existing devices, because their extraction rods are not designed with an extension function, it is difficult to flexibly adjust the length and working coverage according to specific extraction needs. As a result, during the raw material extraction operation, the device can only work on fixed and specific locations, making it difficult to effectively cover raw materials at different depths and in different areas, thus reducing extraction efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a chemical raw material sampling and extraction device. By setting up a lifting part, it solves the problem that the extraction rod is not designed with an extension function, making it difficult to flexibly adjust the length and working coverage according to specific extraction needs. As a result, the device can only work on fixed and specific locations during raw material extraction, making it difficult to effectively cover raw materials at different depths and in different areas, thus reducing extraction efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a chemical raw material sampling and extraction device, comprising a first sleeve section, and further comprising: a lifting part disposed on the first sleeve section; a sampling part disposed on the first sleeve section; the lifting part comprising a lifting assembly mounted on the first sleeve section; and a limiting assembly mounted on the lifting assembly; the lifting assembly comprising two single-sided racks disposed on the inner wall of the first sleeve section, a second sleeve section slidably connected inside the first sleeve section, the second sleeve section having two U-shaped frames, each U-shaped frame having a gear rotatably connected thereto; a third sleeve section slidably connected inside the second sleeve section, the bottom of the third sleeve section having a double-sided rack fixedly connected thereto, both gears meshing with the double-sided racks and the two single-sided racks; the second sleeve section slides on the inner wall of the first sleeve section, and the third sleeve section slides inside the second sleeve section, both being subject to limiting sliding treatment to prevent the third sleeve section and the second sleeve section from rotating or excessively sliding.

[0006] Furthermore, the sampling section includes a sampling component disposed on the third sleeve section; and a winding component disposed on the first sleeve section.

[0007] Furthermore, the limiting component includes several limiting holes formed on the outer wall of the third sleeve. A mounting frame is fixedly connected to the outer wall of the second sleeve. A pressing plate is rotatably connected to the mounting frame. A limiting rod is fixedly connected to the pressing plate. A reset component is provided on the pressing plate. The bottom end of the limiting rod extends into the corresponding limiting hole and slides through it. The reset component includes a telescopic rod fixedly connected to the mounting frame. The other end of the telescopic rod is fixedly connected to the pressing plate. A spring is wound around the outer wall of the telescopic rod. One end of the spring is fixedly connected to the mounting frame, and the other end is fixedly connected to the pressing plate. The several limiting holes on the outer wall of the third sleeve are adapted to the limiting rod on the mounting frame of the second sleeve. The pressing plate drives the limiting rod to insert into the corresponding limiting hole, locking the relative position of the two sleeve sections and achieving length fixation. The telescopic rod in the reset component cooperates with the spring to automatically push the limiting rod back to its original position and lock it in place after the pressing plate is released, ensuring reliable limiting.

[0008] Furthermore, the sampling assembly includes two clamps fixedly connected to the third sleeve section, with a sampling tube fitted onto each clamp. A support frame is fixedly connected to the inner wall of the sampling tube, and a sealing ring is provided at the top of the sampling tube. A pull rod is slidably connected to the support frame, and a sealing piston is fixedly connected to the bottom end of the pull rod. The sealing piston is adapted to the sampling tube. An elastic element is provided on the outer wall of the pull rod, and the top ends of the pull rod extend beyond the sampling tube and the sealing ring and are slidably connected to them. The elastic element includes a second spring wound around the outer wall of the pull rod. One end of the second spring is fixedly connected to the support frame, and the other end of the second spring is fixedly connected to the sealing piston. The two clamps on the third sleeve section can securely fix the sampling tube, ensuring the stability of the tube body during sampling. The support frame on the inner wall of the sampling tube provides sliding support for the pull rod. The sealing piston at the bottom end of the pull rod is adapted to the sampling tube, and together with the top sealing ring, it can ensure the sealing of the sampling tube and prevent sample leakage.

[0009] Furthermore, the winding assembly includes a winding frame fixedly connected to the outer wall of the first sleeve, a winding roller rotatably connected to the winding frame, two knobs sleeved on the outer wall of the winding roller, a lifting rope wound around the outer wall of the winding roller, the bottom end of the lifting rope being fixedly connected to a pull rod, and both ends of the winding roller extending outside the winding frame. The winding frame on the outer wall of the first sleeve provides stable rotational support for the winding roller. By rotating the knobs at both ends of the winding roller, the lifting rope on its outer wall can be wound or unwound, thereby pulling the pull rod of the sampling assembly and realizing convenient operation of the sealing piston.

[0010] This utility model has the following beneficial effects: 1. By setting up a lifting part, the length of the extraction device can be adjusted in actual use. First, press down one end of the pressing plate. With the help of the mounting frame, a rocker effect is formed. The pressing end compresses the telescopic rod and the spring to store force. The other end drives the limit rod to lift up, releasing the lock on the limit hole of the third sleeve. At this time, the second sleeve is pulled out, which drives the gear in the U-shaped frame to move outward. The gear meshes with the rack on one side of the inner wall of the first sleeve and rotates counterclockwise. It pushes the meshing rack on both sides upward. Since the rack on both sides is connected to the third sleeve and the third sleeve slides in the second sleeve, the third sleeve moves outward synchronously with the second sleeve to adjust. After the length is appropriate, the pressing plate is released. Under the reset thrust of the telescopic rod and the spring, the pressing end lifts up and the other end drives the limit rod to re-insert into the limit hole of the third sleeve. By limiting the third sleeve, the second sleeve is fixed simultaneously, realizing the rapid adjustment and stable locking of the device length to meet the sampling needs of different depths. 2. By setting up a sampling section and adjusting the length of the extraction rod, the sampling tube is placed into the chemical raw material at a specified depth for sampling. During sampling, the knob on the winding roller is turned, causing the winding roller to drive the lifting rope to wind up. The lifting rope pulls the pull rod and sealing piston inside the sampling tube upwards, while simultaneously compressing the second spring on the outer wall of the support frame. The sealing piston moves upwards, opening the bottom of the sampling tube, allowing the chemical raw material to enter the tube and complete the sampling. After sampling, the knob is released, and the winding roller drives the lifting rope to rotate freely. Under the reset thrust of the second spring, the pull rod drives the sealing piston to approach the liquid inlet of the sampling tube and reseal it to prevent liquid leakage. This design enables convenient control of the sampling operation and safe retention of the sampled medium.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-6 As shown, this utility model is a chemical raw material sampling and extraction device, including a first sleeve 1, and also includes: a lifting part 2, which is disposed on the first sleeve 1; and a sampling part 3, which is disposed on the first sleeve 1.

[0017] The lifting unit 2 includes a lifting assembly 21, which is mounted on the first sleeve 1; and a limiting assembly 22, which is mounted on the lifting assembly 21. The lifting assembly 21 includes two single-sided racks 211 disposed on the inner wall of the first sleeve 1. A second sleeve 212 is slidably connected inside the first sleeve 1. Two U-shaped frames 213 are disposed on the second sleeve 212, and gears 214 are rotatably connected to each of the two U-shaped frames 213. A third sleeve 215 is slidably connected inside the second sleeve 212. A double-sided rack 216 is fixedly connected to the bottom of the third sleeve 215. Both gears 214 mesh with the double-sided rack 216 and the two single-sided racks 211. The second sleeve 212 slides inside the first sleeve 1. The third sleeve 215 slides inside the second sleeve 212, and both are subject to limiting sliding treatment. The limiting component 22 includes several limiting holes 221 opened on the outer wall of the third sleeve 215. The outer wall of the second sleeve 212 is fixedly connected to a mounting frame 222. A pressing plate 223 is rotatably connected to the mounting frame 222. A limiting rod 224 is fixedly connected to the pressing plate 223. A reset component is provided on the pressing plate 223. The bottom end of the limiting rod 224 extends into the corresponding limiting hole 221 and slides through the corresponding limiting hole 221. The reset component includes a telescopic rod 225 fixedly connected to the mounting frame 222. The other end of the telescopic rod 225 is fixedly connected to the pressing plate 223. The outer wall of the telescopic rod 225 is wound with a spring. Spring 226, one end of which is fixedly connected to the mounting frame 222, and the other end of which is fixedly connected to the pressing plate 223. By setting the lifting part 2, if the length of the extraction device needs to be adjusted in actual use, the following steps can be taken: First, press down on one end of the pressing plate 223. With the help of the mounting frame 222, a rocker effect is formed. The pressed end will compress the telescopic rod 225 and spring 226 above, so that they accumulate elastic potential energy to support subsequent reset. At the same time, the other end of the pressing plate 223 will, with the cooperation of the mounting frame 222, drive the limiting rod 224 on it to lift up, so as to release the lock on the corresponding limiting hole 221 on the third sleeve 215. At this time, the third sleeve 215 can slide freely and then be pulled outward. The second sleeve 212 synchronously drives the rotating gears 214 inside its two U-shaped frames 213 to move outward. Since the two gears 214 mesh with the two single-sided racks 211 fixed to the inner wall of the first sleeve 1, during the outward movement of the gears 214 driven by the second sleeve 212, the two gears 214 will rotate counterclockwise relative to each other through the meshing action with the single-sided racks 211, thereby generating an upward thrust on the double-sided racks 216 that are meshing on one side. Since the double-sided racks 216 are connected to the third sleeve 215, and the third sleeve 215 slides inside the second sleeve 212, when the second sleeve 212 moves outward, it relies on the transmission cooperation of the single-sided racks 211, gears 214, and double-sided racks 216.The third sleeve 215 can be adjusted outwards synchronously with the second sleeve 212. Once the length is adjusted to the appropriate position, the pressing plate 223 can be released. At this time, under the restoring force of the telescopic rod 225 and spring 226, the pressed end of the pressing plate 223 will lift up, and the other end, in cooperation with the mounting frame 222, will drive the limiting rod 224 to re-insert into the corresponding limiting hole 221 on the third sleeve 215. By limiting the third sleeve 215, the second sleeve 212, which is connected to it, can be fixed simultaneously, thereby achieving rapid adjustment and stable locking of the extraction device length to meet sampling requirements at different depths.

[0018] The sampling unit 3 includes a sampling assembly 31, which is mounted on the third sleeve 215; and a winding assembly 32, which is mounted on the first sleeve 1. The sampling assembly 31 includes two clamps 311 fixedly connected to the third sleeve 215, and a sampling tube 312 is fitted onto the two clamps 311. A support frame 313 is fixedly connected to the inner wall of the sampling tube 312. A sealing ring 314 is provided at the top of the sampling tube 312. A pull rod 315 is slidably connected to the support frame 313. A sealing piston 316 is fixedly connected to the bottom end of the pull rod 315. The sealing piston 316 is adapted to the sampling tube 312. An elastic element is provided on the outer wall of the pull rod 315. The top ends of the pull rods 315 extend to the outside of the sampling tube 312 and the sealing ring 314 and are slidably connected to them. The winding assembly 32 includes a winding frame 321 fixedly connected to the outer wall of the first sleeve 1. A winding roller 322 is rotatably connected to the winding frame 321. Two knobs 323 are sleeved on the outer wall of the winding roller 322. A lifting rope 324 is wound around the outer wall of the winding roller 322. The bottom end of the lifting rope 324 is fixedly connected to the pull rod 315. Both ends of the winding roller 322 extend to the outside of the winding frame 321. The elastic element includes a second spring 317 wound around the outer wall of the pull rod 315. One end of the second spring 317 is fixedly connected to the support frame 313. The other end of spring 317 is fixedly connected to the sealing piston 316. After the sampling section 3 is set and the length of the extraction rod is adjusted, it can be used to put the sampling tube 312 into the chemical raw material at a specified depth for sampling. During sampling, simply turn the knob 323 on the winding roller 322 to make the winding roller 322 drive the lifting rope 324 wound around the outer wall to wind up. Since the other end of the lifting rope 324 is connected to the pull rod 315 sliding inside the sampling tube 312, the pull rod 315 will drive the sealing piston 316 on it to move up during the winding process of the lifting rope 324. At the same time, in conjunction with the support frame 313 inside the sampling tube 312, the spring 317 on its outer wall is compressed. 7. To accumulate energy and provide power for subsequent reset, as the sealing piston 316 gradually moves upward, the bottom of the sampling tube 312 will be gradually opened, and the chemical raw materials can enter the sampling tube 312 to complete the sampling operation. After the sampling is completed, simply loosen the knob 323 on the winding roller 322 to allow the winding roller 322 to drive the lifting rope 324 to rotate freely. At this time, the pull rod 315 connected to the lifting rope 324 will be driven by the reset thrust of the spring 317 to move the sealing piston 316 closer to the liquid inlet of the sampling tube 312 and reseal it, effectively preventing liquid leakage after sampling. Through this design, convenient control of the sampling operation and safe retention of the sampling medium can be achieved.

[0019] A specific application of this embodiment is as follows: In actual use, if it is necessary to adjust the length of the extraction device, the following steps can be taken: First, press down on one end of the pressing plate 223. With the help of the mounting frame 222, a rocker effect is formed. The pressed end will compress the telescopic rod 225 and the spring 226 above, allowing them to accumulate elastic potential energy to support subsequent reset. At the same time, the other end of the pressing plate 223 will, with the cooperation of the mounting frame 222, cause the limiting rod 224 on it to tilt up, thereby releasing the third sleeve 215. With the upper limit hole 221 locked, the third sleeve 215 can slide freely. Then, the second sleeve 212 is pulled outward, which will simultaneously drive the rotating gears 214 inside its two U-shaped frames 213 to move outward. Since the two gears 214 mesh with the two single-sided racks 211 fixed on the inner wall of the first sleeve 1, during the process of the second sleeve 212 driving the gears 214 to move outward, through the meshing action with the single-sided racks 211, the two gears 214 will move in opposite directions. As the clock hand rotates, it generates an upward thrust on the double-sided racks 216 that are meshing close to each other. Because the double-sided racks 216 are connected to the third sleeve 215, and the third sleeve 215 slides inside the second sleeve 212, when the second sleeve 212 moves outward, the third sleeve 215 can move outward synchronously with the second sleeve 212 through the transmission cooperation of the single-sided rack 211, gear 214, and double-sided racks 216. Once the length is adjusted to the appropriate position, the pressing plate can be released. 223. At this time, the pressing plate 223 will be pushed up by the resetting force of the telescopic rod 225 and the spring 226, and the other end will be driven by the mounting frame 222 to re-insert the limiting rod 224 into the corresponding limiting hole 221 on the third sleeve 215. By limiting the third sleeve 215, the second sleeve 212 connected to it can be fixed simultaneously, thereby realizing the rapid adjustment and stable locking of the length of the extraction device to meet the sampling requirements of different depths.After the extraction rod length is adjusted, it can be used to place the sampling tube 312 into the chemical raw material at a specified depth for sampling. During sampling, simply turn the knob 323 on the take-up roller 322 to cause the take-up roller 322 to drive the lifting rope 324 wound around the outer wall to take up the sample. Since the other end of the lifting rope 324 is connected to the pull rod 315 sliding inside the sampling tube 312, during the take-up process of the lifting rope 324, the pull rod 315 will drive the sealing piston 316 on it to move upward. At the same time, in conjunction with the support frame 313 inside the sampling tube 312, the spring 317 on its outer wall is compressed to accumulate energy and provide power for subsequent resetting. As the sealing piston 316 gradually moves upward, the bottom of the sampling tube 312 will be gradually opened, allowing the chemical raw material to enter the sampling tube 312 and complete the sampling operation. After sampling, simply loosen the knob 323 on the take-up roller 322, allowing the take-up roller 322 to drive the lifting rope 324 to rotate freely. At this time, the pull rod 315 connected to the lifting rope 324 will, under the reset thrust of the spring 317, drive the sealing piston 316 to approach the liquid inlet of the sampling tube 312 and reseal it, effectively preventing liquid leakage after sampling. This design enables convenient control of the sampling operation and safe retention of the sampled medium.
