Description

Technical Field

[0001] The utility model relates to the technical field of samplers, in particular to a synchronous multi-level depth sampler. Background Technique

[0002] Acetic anhydride is an organic compound with the chemical formula (CH3CO)2O, and it is the anhydride of acetic acid. The reaction between acetic anhydride and water is a hydrolysis reaction. Hydrolysis refers to the chemical reaction of a compound with water to produce a new compound. Acetic anhydride and water undergo a hydrolysis reaction to form acetic acid. The hydrolysis reaction is usually carried out under heating conditions because temperature can affect the reaction rate and the thoroughness of the reaction. Generally speaking, the hydrolysis reaction of acetic anhydride and water is very slow at room temperature, while the reaction is faster under heating conditions. The specific reaction temperature depends on the concentration of the reactants, the reaction time, and the reaction conditions.

[0003] In the sampling operation during the reaction process of the existing sampler for acetic anhydride reaction liquid, synchronous multi-level depth sampling cannot be achieved, the sampling efficiency is low, the sampling is inconvenient, and after sampling, the reaction liquid often adheres to the outer side wall of the sampler, resulting in waste of resources, low utilization rate, and poor practicability. For this reason, we propose a synchronous multi-level depth sampler. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a synchronous multi-level depth sampler, which can achieve synchronous multi-level depth sampling, has a higher sampling efficiency, is convenient for sampling, and can scrape the reaction liquid adhered to the outside of the sampler, avoiding waste of resources, having a higher utilization rate, and having a higher practicability, and can effectively solve the problems in the background technique.

[0005] To achieve the above object, the utility model provides the following technical solution: A synchronous multi-level depth sampler includes a sampler;

[0006] An accommodation cavity is provided inside the sampler, three uniformly distributed sampling containers are provided inside the accommodation cavity, two adjacent sampling containers are fixedly adjacent through a connecting vertical rod, a cavity is provided inside the sampling container, a sampling assembly is provided inside the cavity, a connecting column is fixedly connected to the bottom end of the lowermost sampling container, the connecting column is connected to an adjusting assembly, sealing assemblies are provided at the bottom ends of the upper two sampling containers, and a limiting assembly is provided on the upper side of the lowermost sampling container;

[0007] The setting of three uniformly distributed sampling containers can sample the reaction liquid simultaneously, can achieve synchronous multi-level depth sampling, has a higher sampling efficiency, and is convenient for sampling.

[0008] Further, the sampling assembly includes a telescopic hose, a liquid extraction pump, and a connecting diversion pipe. A liquid extraction pump is fixedly arranged inside the inner cavity of the sampling container. The liquid inlet at the right end of the liquid extraction pump is communicated with the liquid outlet of the telescopic hose. The telescopic hose passes through the sampling container and extends into the sampler. The liquid outlet at the top of the liquid extraction pump is communicated with the liquid inlet of the connecting diversion pipe. A limiting disc is fixedly connected to the top of each sampling container. The connecting diversion pipe passes through the middle of the limiting disc and extends into the sampler. Two uniformly distributed sampling ports are arranged on the outer side of the sampler.

[0009] By adjusting the assembly to align the telescopic hose with the sampling port, starting the liquid extraction pump, and guiding the reaction liquid into the sampler through the telescopic hose and the connecting diversion pipe, each sampling assembly can perform sampling synchronously, achieving multi-stage deep sampling.

[0010] Further, the sealing assembly includes a connecting bottom plate and a sealing plate. The bottoms of the two upper sampling containers are fixedly connected with connecting bottom plates through fastening bolts. The outer ends of the connecting bottom plates are fixedly connected with sealing plates, and the sealing plates are slidably connected to the inner wall of the sampler.

[0011] The arrangement of the connecting bottom plate and the sealing plate makes the sealing plate correspond to the position of the sampling port when not sampling, keeping the inside of the sampler sealed. When sampling, the sealing assembly will move synchronously with the sampling container, opening the sampling port for sampling.

[0012] Further, the limiting assembly includes a limiting disc, a limiting vertical rod, and a braking plate. A limiting vertical rod is fixedly connected to the upper side of the lowermost limiting disc. The top of the limiting vertical rod is fixedly connected with a braking plate, and the braking plate is slidably connected to the inner wall of the braking groove opened on the inner wall of the sampler. The total height of the limiting assembly is the same as the height that the adjusting assembly can adjust.

[0013] When the adjusting assembly adjusts the sampling container to move downward, the braking plate slides horizontally in the braking groove along with it until it reaches the critical position, and the braking plate is clamped at the end of the braking groove. At this time, the telescopic hose is aligned with the sampling port, and the lowermost telescopic hose corresponds to the reaction liquid, enabling synchronous sampling, which is convenient and efficient for sampling.

[0014] Further, the adjusting assembly includes a rectangular groove, a U-shaped connecting frame, and a cylindrical compression spring. A vertically distributed rectangular groove is opened at the upper end of the sampler. The inside of the rectangular groove is slidably connected to the upper side of the U-shaped connecting frame. A cylindrical compression spring is fixedly connected to the middle of the upper side of the U-shaped connecting frame. The top of the cylindrical compression spring is fixedly connected to the middle of the upper side of the rectangular groove. The lower side of the U-shaped connecting frame is fixedly sleeved outside the connecting column, and a scraping assembly is arranged inside the U-shaped connecting frame.

[0015] Push the U-shaped connecting frame downward. The lower side of the U-shaped connecting frame can move the connecting column downward, so that the sampling container at the bottom drives the two sampling containers on the upper side to move downward simultaneously. Move to the position where the telescopic hose is aligned with the sampling port and reach the braking position at the same time. The three telescopic hoses can extract the reaction liquid. After sampling, stop pushing the U-shaped connecting frame. The cylindrical compression spring will stretch the U-shaped connecting frame upward to reset and stop sampling.

[0016] Furthermore, the scraping assembly includes a sliding frame, a connecting frame, scraping rings, auxiliary chutes, auxiliary sliders, pneumatic push rods and telescopic guide rods. The sliding frame is slidably connected to the inner side of the U-shaped connecting frame. The lower side of the sliding frame is fixedly connected to the connecting frame. Scraping rings are fixedly connected to the right ends of both the sliding frame and the connecting frame. Each scraping ring is slidably sleeved on the outside of the sampler. Auxiliary chutes are provided on the inner side wall of the U-shaped connecting frame. Auxiliary sliders are slidably arranged inside the auxiliary chutes. The auxiliary sliders are fixedly connected to the inner side of the sliding frame. The top of the sliding frame is fixedly connected to the pneumatic push rod and the telescopic guide rod respectively. The tops of the pneumatic push rod and the telescopic guide rod are fixedly connected to the inner side of the U-shaped connecting frame.

[0017] By controlling the pneumatic push rod, the sliding frame and the connecting frame can be pushed to move downward simultaneously. The auxiliary sliders can move up and down in the auxiliary chutes to assist in guiding the movement of the sliding frame. The telescopic guide rods play a role in guiding the vertical direction. Thus, the three scraping rings can scrape up and down synchronously to scrape off the reaction liquid adhering to the outside of the sampler, avoiding waste of resources, having a high utilization rate and high practicability.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows: This synchronous multi-stage depth sampler has the following advantages:

[0019] 1. Through the arrangement of three evenly distributed sampling containers, the reaction liquid can be sampled simultaneously, realizing synchronous multi-stage depth sampling, with high sampling efficiency and convenient sampling.

[0020] 2. By pushing the U-shaped connecting frame downward, the lower side of the U-shaped connecting frame can move the connecting column downward, so that the sampling container at the bottom drives the two sampling containers on the upper side to move downward simultaneously. Move to the position where the telescopic hose is aligned with the sampling port and reach the braking position at the same time. The three telescopic hoses can extract the reaction liquid. After sampling, stop pushing the U-shaped connecting frame. The cylindrical compression spring will stretch the U-shaped connecting frame upward to reset and stop sampling.

[0021] 3. By controlling the pneumatic push rod, the sliding frame and the connecting frame can be pushed to move downward simultaneously. The auxiliary sliders can move up and down in the auxiliary chutes to assist in guiding the movement of the sliding frame. The telescopic guide rods play a role in guiding the vertical direction. Thus, the three scraping rings can scrape up and down synchronously to scrape off the reaction liquid adhering to the outside of the sampler, avoiding waste of resources, having a high utilization rate and high practicability.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-5 , this embodiment provides a technical solution: a synchronous multi-stage depth sampler includes a sampler 1;

[0030] An accommodation cavity is provided inside the sampler 1. Three evenly distributed sampling containers 11 are provided inside the accommodation cavity. Adjacent two sampling containers 11 are fixedly connected adjacent to each other through a connecting vertical rod 12. A cavity is provided inside the sampling container 11. A sampling component 2 is provided inside the cavity. A connecting column 13 is fixedly connected to the bottom end of the lowermost sampling container 11. The connecting column 13 is connected to an adjusting component 5. Sealing components 3 are provided at the bottom ends of the upper two sampling containers 11. A limiting component 4 is provided on the upper side of the lowermost sampling container 11;

[0031] The setting of three uniformly distributed sampling containers 11 enables simultaneous sampling of the reaction solution, achieving synchronous multi-level deep sampling with relatively high sampling efficiency and convenience.

[0032] Among them, the sampling assembly 2 includes a telescopic hose 21, a liquid extraction pump 22, and a connecting and guiding pipe 23. A liquid extraction pump 22 is fixedly arranged inside the inner cavity of the sampling container 11. The right end liquid inlet of the liquid extraction pump 22 is communicated with the liquid outlet of the telescopic hose 21. The telescopic hose 21 passes through the sampling container 11 and extends into the sampler 1. The top liquid outlet of the liquid extraction pump 22 is communicated with the liquid inlet of the connecting and guiding pipe 23. A limiting disc 41 is fixedly connected to the top of each sampling container 11. The connecting and guiding pipe 23 passes through the middle of the limiting disc 41 to the inside of the sampler 1. Two uniformly distributed sampling ports 24 are arranged on the outer side of the sampler 1.

[0033] By adjusting the assembly 5 to align the telescopic hose 21 with the sampling port 24, starting the liquid extraction pump 22, and guiding the reaction solution into the sampler 1 through the telescopic hose 21 and the connecting and guiding pipe 23, each sampling assembly 2 can perform sampling synchronously, achieving multi-level deep sampling.

[0034] The sealing assembly 3 includes a connecting bottom plate 31 and a sealing plate 32. The bottom ends of the two upper sampling containers 11 are fixedly connected with connecting bottom plates 31 through fastening bolts. The outer ends of the connecting bottom plates 31 are fixedly connected with sealing plates 32. The sealing plates 32 are slidably connected to the inner wall of the sampler 1.

[0035] The setting of the connecting bottom plate 31 and the sealing plate 32 makes the sealing plate 32 correspond to the position of the sampling port 24 when not sampling, keeping the inside of the sampler 1 in a sealed state. When sampling, the sealing assembly 3 will move synchronously with the sampling container 11 to open the sampling port 24 for sampling.

[0036] The limiting assembly 4 includes a limiting disc 41, a limiting vertical rod 42, and a braking plate 43. A limiting vertical rod 42 is fixedly connected to the upper side of the lowermost limiting disc 41. The top of the limiting vertical rod 42 is fixedly connected with a braking plate 43. The braking plate 43 is slidably connected to the inner wall of the braking groove opened on the inner wall of the sampler 1. The total height of the limiting assembly 4 is the same as the height that the adjusting assembly 5 can adjust.

[0037] When the adjusting assembly 5 adjusts the sampling container 11 to move downward, the braking plate 43 slides horizontally in the braking groove until it reaches the critical position, and the braking plate 43 is clamped at the end of the braking groove. At this time, the telescopic hose 21 is aligned with the sampling port 24, and the lowermost telescopic hose 21 corresponds to the reaction solution, enabling synchronous sampling with high convenience and efficiency.

[0038] The adjusting assembly 5 includes a rectangular groove 51, a U-shaped connecting frame 52 and a cylindrical compression spring 53. A vertically distributed rectangular groove 51 is opened at the upper end of the sampler 1. The inside of the rectangular groove 51 is slidably connected to the upper side of the U-shaped connecting frame 52. A cylindrical compression spring 53 is fixedly connected to the middle of the upper side of the U-shaped connecting frame 52. The top of the cylindrical compression spring 53 is fixedly connected to the middle of the upper side of the rectangular groove 51. The lower side of the U-shaped connecting frame 52 is fixedly sleeved outside the connecting column 13. A scraping assembly 6 is provided inside the U-shaped connecting frame 52.

[0039] Push the U-shaped connecting frame 52 downward. The lower side of the U-shaped connecting frame 52 can move the connecting column 13 downward, so that the sampling container 11 at the bottom drives the two sampling containers 11 on the upper side to move downward simultaneously until the telescopic hose 21 is aligned with the sampling port 24 and reaches the braking position. The three telescopic hoses 21 can extract the reaction liquid. After sampling is completed, stop pushing the U-shaped connecting frame 52. The cylindrical compression spring 53 will stretch the U-shaped connecting frame 52 upward to reset and stop sampling.

[0040] The scraping assembly 6 includes a sliding frame 61, a connecting frame 62, scraping rings 63, auxiliary sliding grooves 64, auxiliary sliders 65, pneumatic push rods 66 and telescopic guide rods 67. The sliding frame 61 is slidably connected inside the U-shaped connecting frame 52. The lower side of the sliding frame 61 is fixedly connected to the connecting frame 62. Scraping rings 63 are fixedly connected to the right ends of both the sliding frame 61 and the connecting frame 62. Each scraping ring 63 is slidably sleeved outside the sampler 1. Auxiliary sliding grooves 64 are opened on the inner side wall of the U-shaped connecting frame 52. Auxiliary sliders 65 are slidably arranged inside the auxiliary sliding grooves 64. The auxiliary sliders 65 are fixedly connected to the inner side of the sliding frame 61. The top of the sliding frame 61 is fixedly connected to the pneumatic push rod 66 and the telescopic guide rod 67 respectively. The tops of the pneumatic push rod 66 and the telescopic guide rod 67 are fixedly connected to the inner side of the U-shaped connecting frame 52.

[0041] By controlling the pneumatic push rod 66, the sliding frame 61 and the connecting frame 62 can be pushed to move downward simultaneously. The auxiliary slider 65 can move up and down in the auxiliary sliding groove 64 to assist in guiding the movement of the sliding frame 61. The telescopic guide rod 67 plays a role in guiding in the vertical direction, so that the three scraping rings 63 can scrape up and down synchronously to scrape off the reaction liquid adhered to the outside of the sampler 1, avoiding waste of resources, having a high utilization rate and high practicability.

[0042] The working principle of a synchronous multi-stage depth sampler provided by the present utility model is as follows: The setting of three uniformly distributed sampling containers 11 enables simultaneous sampling of the reaction liquid, achieving synchronous multi-stage depth sampling with relatively high sampling efficiency and convenience. By adjusting the component 5 to align the telescopic hose 21 with the sampling port 24 and starting the liquid extraction pump 22, the reaction liquid is diverted into the sampler 1 through the telescopic hose 21 and the connecting diversion pipe 23. Each sampling component 2 samples simultaneously, realizing multi-stage depth sampling. The connecting bottom plate 31 and the sealing plate 32 are provided. When not sampling, the sealing plate 32 corresponds to the position of the sampling port 24, keeping the inside of the sampler 1 sealed. When sampling, the sealing component 3 moves synchronously with the sampling container 11 to open the sampling port 24 for sampling. When the adjusting component 5 adjusts the sampling container 11 to move downward, the brake plate 43 slides horizontally in the brake groove until it reaches the critical position, and the brake plate 43 is clamped at the end of the brake groove. At this time, the telescopic hose 21 is aligned with the sampling port 24, and the lowermost telescopic hose 21 corresponds to the reaction liquid, enabling synchronous sampling, which is convenient and efficient. Pushing the U-shaped connecting frame 52 downward, the lower side of the U-shaped connecting frame 52 can move the connecting column 13 downward, so that the lowermost sampling container 11 drives the two upper sampling containers 11 to move downward simultaneously until the telescopic hoses 21 are aligned with the sampling ports 24 and reach the braking position. The three telescopic hoses 21 can extract the reaction liquid. After sampling is completed, stop pushing the U-shaped connecting frame 52, and the cylindrical compression spring 53 will stretch the U-shaped connecting frame 52 upward to reset and stop sampling. By controlling the pneumatic push rod 66, the sliding frame 61 and the connecting frame 62 can be pushed to move downward simultaneously. The auxiliary slider 65 can move up and down in the auxiliary chute 64 to assist in guiding the movement of the sliding frame 61, and the telescopic guide rod 67 plays a role in guiding the vertical direction. Thus, the three scraping rings 63 can scrape up and down synchronously to scrape off the reaction liquid adhering to the outside of the sampler 1, avoiding resource waste, with high utilization rate and high practicability.

[0043] The above are only embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
