Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-6 , a sampling and detection device for safe production of liquid chemical raw materials, comprising a sampling box 1, wherein a liquid chemical raw material sampling structure 5 and a cleaning mechanism 6 are arranged inside the sampling box 1;

[0031] The liquid chemical raw material sampling structure 5 includes a fixed plate 501, a liquid pump 502, a plug-in plate 503, a storage box 504, a fixed base 505, a limit slide 506, a spring 507, a sliding sleeve 508, a clamping ring 509, a limit ring 510, a material injection hose 511, a connecting pipe 512, a universal rotary joint 513 and a liquid chemical raw material sample tank 514. The sampling box 1 is fixedly installed with a fixed plate 501 inside, a liquid pump 502 is fixedly installed on the top of the fixed plate 501, a plug-in plate 503 is plugged into the bottom of the fixed plate 501, and a storage box 504 is fixedly installed at the bottom of the plug-in plate 503. Four fixed bases 505 are fixedly installed inside the storage box 504, each of which has a plurality of fixed bases 505. A liquid chemical raw material sample tank 514 is inserted into the interior of each fixed base 505, and six limit slide bars 506 are fixedly installed inside the storage box 504. A spring 507 is sleeved on the outside of each limit slide bar 506, and a sliding sleeve 508 is slidably connected to the outside of each limit slide bar 506. A clamping ring 509 is fixedly installed between every two sliding sleeves 508. A limit ring 510 is fixedly installed on the outside of each liquid chemical raw material sample tank 514, and a filling hose 511 is fixedly installed on the left side of the liquid pump 502. Four connecting pipes 512 are fixedly installed on the outside of the filling hose 511, and a universal rotating joint 513 is provided at the bottom of each connecting pipe 512.

[0032] Furthermore, the cleaning mechanism 6 includes a plug-in hole 601, a cleaning pipe 602, a liquid storage tank 603, a water injection pump 604, an equipment box 605, a cleaning wastewater collecting hose 606, a first pipe joint 607 and a wastewater collecting tank 608. A plug-in hole 601 is opened on the left side of the sampling box 1, a cleaning pipe 602 is fixedly installed on the inner left wall of the sampling box 1, a liquid storage tank 603 is fixedly installed inside the sampling box 1, a water injection pump 604 is fixedly installed inside the sampling box 1, a equipment box 605 is fixedly installed inside the sampling box 1, a cleaning wastewater collecting hose 606 is fixedly installed inside the equipment box 605, four first pipe joints 607 are fixedly installed on the outside of the cleaning wastewater collecting hose 606, and a wastewater collecting tank 608 is fixedly installed inside the sampling box 1.

[0033] Specifically, when it is necessary to clean the pipeline of the liquid chemical raw material sampling structure 5, the water injection pump 604 will transport the cleaning liquid in the liquid storage tank 603 to the extraction head 4 through the cleaning pipe 602, and then return it to the cleaning wastewater collection hose 606 through the extraction head 4, and finally discharge it into the wastewater collection tank 608. This process is fully automated and does not require human intervention, which greatly saves cleaning time and reduces the complexity of cleaning.

[0034] Furthermore, a connecting hose 2 is fixedly installed on the left side of the sampling box 1, a handle 3 is fixedly installed on the end of the connecting hose 2 away from the sampling box 1, a suction head 4 is fixedly installed on the end of the handle 3 away from the connecting hose 2, two carrying straps 7 are fixedly installed on the back of the sampling box 1, and a box door is movably installed on the front of the sampling box 1.

[0035] Specifically, the presence of the carrying strap 7 allows the staff to carry the sampling box 1, reducing the pressure of carrying heavy objects, especially in a working environment that requires frequent movement. The combined design of the connecting hose 2, the handle 3 and the extraction head 4 allows the user to easily extract liquid chemical raw materials from the container, and the design of the box door facilitates the maintenance of the internal components of the sampling box 1.

[0036] Furthermore, a partition is fixedly installed inside the storage box 504, wherein two fixed bases 505 are fixedly installed on the inner bottom wall of the sampling box 1, and the other two fixed bases 505 are fixedly installed on the top of the partition, six limiting slide bars 506 are respectively located at the top and bottom of the partition, and four liquid chemical raw material sample tanks 514 are respectively located at the top and bottom of the partition.

[0037] Specifically, four liquid chemical raw material sample tanks 514 are reasonably placed and fixed inside the sampling box 1, and six limiting slide bars 506, together with springs 507, sliding sleeves 508 and clamping rings 509, form a flexible clamping system to ensure the stability of the liquid chemical raw material sample tanks 514 inside the sampling box 1.

[0038] Furthermore, the tops of three of the springs 507 are fixedly connected to the inner top wall of the storage box 504 , the tops of another three springs 507 are fixedly connected to the bottom of the partition, and the bottoms of the six springs 507 are fixedly connected to the tops of the six sliding sleeves 508 , respectively.

[0039] Specifically, the function of the spring 507 is to facilitate the fixation of the liquid chemical raw material sample tank 514. When the liquid chemical raw material sample tank 514 needs to be disassembled, the clamping ring 509 is lifted upward, the spring 507 contracts, and the clamping ring 509 is separated from the outside of the liquid chemical raw material sample tank 514. At this time, the liquid chemical raw material sample tank 514 is lifted upward to realize the disassembly of the liquid chemical raw material sample tank 514.

[0040] Furthermore, second pipe joints are fixedly installed on the tops of the four liquid chemical raw material sample tanks 514, and the four second pipe joints are threadedly connected to the four universal rotating joints 513 respectively. The right side of the connecting hose 2 passes through the left side of the sampling box 1 and is connected to the liquid pump 502. Two first electric control valves are fixedly installed inside the injection hose 511, and second electric control valves are fixedly installed inside the four connecting pipes 512.

[0041] Specifically, the first electric control valve and the second electric control valve control the pipeline of the liquid chemical raw material sampling structure 5, so that the chemical raw materials can enter the interior of four liquid chemical raw material sample tanks 514 at one time. By accurately controlling the opening and closing of the first electric control valve and the second electric control valve, it can be ensured that each liquid chemical raw material sample tank 514 receives the same volume of liquid chemical raw material, thereby ensuring the accuracy and consistency of sampling.

[0042] Furthermore, the plug hole 601 and the cleaning pipe 602 are both compatible with the extraction head 4, and a first delivery pipe connected to the cleaning pipe 602 is fixedly installed on the top of the water injection pump 604, and a second delivery pipe connected to the liquid storage tank 603 is fixedly installed on the bottom of the water injection pump 604. The four first pipe joints 607 are respectively compatible with the four universal rotating joints 513.

[0043] Specifically, when cleaning the pipeline of the liquid chemical raw material sampling structure 5, it is first necessary to pass the sampling head 4 through the plug hole 601 on the left side of the sampling box 1 and insert it into the cleaning pipe 602;

[0044] Next, start the water injection pump 604, extract the cleaning liquid from the liquid storage tank 603 through the second delivery pipe at the bottom, and deliver the cleaning liquid to the cleaning pipe 602 through the first delivery pipe at the top. At this time, the cleaning liquid enters the pipeline of the liquid chemical raw material sampling structure 5 through the extraction head 4, and starts to circulate and clean the entire sampling path. After passing through the sampling path, the cleaning liquid flows back to the cleaning wastewater collection hose 606 through the first pipe joint 607 and the universal rotating joint 513, and is finally collected in the wastewater collection tank 608.

[0045] Furthermore, the top of the cleaning wastewater collection hose 606 passes through the inner top wall of the equipment box 605 and is connected to the wastewater collection box 608. The right sides of the liquid storage tank 603 and the wastewater collection box 608 are respectively fixed with an injection pipe and a drainage pipe, and the inside of the injection pipe and the drainage pipe are fixed with switch control valves.

[0046] Specifically, when sampling different types of liquid chemical raw materials, the sampling and detection device provides an efficient and safe operation process. First, a chemical raw material is sampled through the liquid chemical raw material sampling structure 5. The specific steps are as follows:

[0047] Step 1: Use the extraction head 4 to extract the required liquid chemical raw materials from the container;

[0048] Step 2: The extracted raw materials are sent into the injection hose 511 through the connecting hose 2 and the liquid pump 502, and then distributed to four liquid chemical raw material sample tanks 514 through the connecting pipe 512 and the universal rotating joint 513. In this process, the first electric control valve and the second electric control valve can accurately control the flow of the raw materials to ensure that each liquid chemical raw material sample tank 514 receives an accurate sample amount;

[0049] Step 3: After sampling is completed, the liquid chemical raw material sample tank 514 containing the sample is removed and prepared for cleaning;

[0050] Next, the cleaning mechanism 6 is used to thoroughly clean the pipeline of the liquid chemical raw material sampling structure 5 to prevent cross contamination between different batches or types of chemical raw materials. The cleaning steps are as follows:

[0051] Step 1: Insert the extraction head 4 into the cleaning pipe 602 through the plug hole 601;

[0052] Step 2: Start the water injection pump 604 to deliver the cleaning liquid in the liquid storage tank 603 to the cleaning pipe 602 through the first delivery pipe;

[0053] Step 3: The cleaning liquid enters the pipeline of the liquid chemical raw material sampling structure 5 through the extraction head 4, and circulates to clean the entire system;

[0054] Step 4: The cleaned wastewater flows back to the wastewater collection tank 608 through the cleaning wastewater collection hose 606 and the first pipe joint 607;

[0055] After cleaning, install the new liquid chemical raw material sample tank 514 into the sampling box 1, and start sampling another chemical raw material, which greatly saves time, improves work efficiency, and ensures that each sampling is thoroughly cleaned to avoid the risk of cross contamination.

[0056] Furthermore, there are four clamping rings 509 , which are respectively sleeved on the outside of four liquid chemical raw material sample tanks 514 , and respectively fit with the limiting rings 510 on the outside of the four liquid chemical raw material sample tanks 514 .

[0057] Specifically, the combined use of the clamping ring 509 and the limiting ring 510 can ensure that the liquid chemical raw material sample tank 514 is stably fixed inside the sampling box 1, reducing the risk of leakage or damage of the liquid chemical raw material sample tank 514 due to shaking, and improving the safety of the sampling process. The clamping function of the clamping ring 509 simplifies the installation and disassembly process of the liquid chemical raw material sample tank 514, and there is no need for additional manual adjustment of the fixing device, thereby improving work efficiency.

[0058] In summary, the sampling and detection device for safe production of liquid chemical raw materials realizes automatic extraction and injection of samples through the liquid chemical raw material sampling structure 5, reduces direct contact of workers and improves safety; specifically, the sampling box 1 is provided with components such as a liquid pump 502, an injection hose 511 and a connecting pipe 512. The liquid pump 502 extracts liquid chemical raw materials through the connecting hose 2 and the extraction head 4, and then distributes them to four liquid chemical raw material sample tanks 514 through the injection hose 511 and four connecting pipes 512. The universal rotating joint 513 at the bottom of each connecting pipe 512 ensures that the liquid chemical raw material sample tank 514 can be removed from the sampling box 1. At the same time, the design of the clamping ring 509 and the limit ring 510 ensures the safe placement and fixation of the liquid chemical raw material sample tank 514; this process avoids the risks brought by manual operation, and also speeds up the sampling speed and improves efficiency.

[0059] In addition, the sampling and detection device for safe production of liquid chemical raw materials can quickly and effectively complete the cleaning work after sampling by setting up a cleaning mechanism 6, so as to prevent cross contamination between different batches or types of chemical raw materials; the cleaning mechanism 6 includes a cleaning pipe 602, a liquid storage tank 603, a water injection pump 604 and a cleaning wastewater collection hose 606, etc. When in use, the cleaning liquid in the liquid storage tank 603 is transported to the extraction head 4 through the cleaning pipe 602 by the water injection pump 604, and then refluxed to the cleaning wastewater collection hose 606 through the extraction head 4, and finally discharged into the wastewater collection tank 608. This process is fully automated and does not require manual intervention, which greatly saves cleaning time and reduces the complexity of cleaning. In addition, since the cleaning system is independent, it can be ensured that the cleaning liquid is cleaned after each sampling. It can be thoroughly cleaned and avoid the risk of cross contamination. This automated cleaning mechanism not only simplifies the cleaning steps, but also improves the continuity and efficiency of the overall work, and solves the problem of inconvenience in actual operation when facing multiple batches and different types of chemical raw materials sampling. First, workers need to manually inject the sampled chemical raw materials into the sample tank, which not only increases the risk of workers contacting dangerous chemical raw materials, but also poses a safety hazard. Secondly, in order to avoid cross contamination, a new detection sampler needs to be replaced after each sampling, or the sampler needs to be manually cleaned. The process is cumbersome and time-consuming, which affects work efficiency. Therefore, the chemical industry has an urgent need for the improvement and innovation of sampling and detection devices to achieve safer, more efficient and convenient sampling operations.
