Description

Technical Field

[0001] The utility model relates to the technical field of liquid density detection devices, in particular to a liquid density component analysis sampling device. Background Art

[0002] In the field of industrial control, there are various sampling devices, such as density, pressure, flow, liquid level, component analysis, etc., especially the accuracy and stability of density and component sampling are extremely important. The accuracy of density and component values is related to the stable operation of the entire system. For example, in lime slurry desulfurization system and SNCR urea denitrification system, too high density of lime slurry is not conducive to desulfurization, but will increase the wear of the conveying pipeline and conveying pump, and sharply increase the production and operation costs. A suitable density value is particularly critical.

[0003] The existing sampling and analysis method is to manually use a sampling bucket and a sampling rope. The sampling bucket is placed in the liquid to be sampled, and then the sampling rope is pulled to sample. The existing sampling method has obvious defects:

[0004] 1. Manual sampling is required, which is dangerous and the sampler may fall into the solution pool easily;

[0005] 2. Most solution pools or solution tanks have agitators, which prevent the sampling bucket from being placed in the middle of the sampling pool for sampling. If the sampling bucket is placed in the middle of the solution pool, it is easy to be entangled by the agitator, thus triggering a greater safety accident.

[0006] 3. The samples taken are greatly affected by human factors, and the samplers may be careless and obtain inaccurate samples;

[0007] 4. The sampling interval cannot be accurately spaced, and the real-time density value cannot be obtained in time.

[0008] After searching the relevant Chinese utility model patents, it is known that the authorization announcement numbers "CN217059811U" and "CN219914971U" disclose a liquid density detection device and an easy-to-clean sampling device. To ensure the accuracy of each sampling and analysis data, the analysis device needs to be cleaned after each analysis. However, both the liquid density detection device and the easy-to-clean sampling device need to be disassembled before cleaning, which is not conducive to multiple sampling and analysis, that is, the cleaning steps are relatively cumbersome. Utility Model Content

[0009] The purpose of the present utility model is to solve at least one of the technical problems existing in the prior art and to provide a liquid density component analysis sampling device, which can solve the problem that the existing analysis sampling device needs to be disassembled before it can be cleaned, and when multiple sampling and analysis are performed, it needs to be disassembled and cleaned back and forth to ensure the accuracy of the sampling analysis data.

[0010] To achieve the above-mentioned object, the present utility model provides the following technical solutions: a liquid density component analysis sampling device, comprising a solution tank;

[0011] The sampling and analysis component is arranged on the solution tank, and includes a sampling pipe, a sampling valve, a second connecting ring, a threaded hole, an external threaded ring, a first connecting ring, a density detector, a circular ring and a detection pipe. The sampling pipe is adhered to the solution tank, and the sampling valve is installed on the sampling pipe;

[0012] The cleaning assembly is set on the density detector. The cleaning assembly includes a water inlet pipe, a flushing valve, a connecting pipe, a sample outlet pipe and a drain valve. The sample outlet pipe is connected to the lower side of the density detector, and the drain valve is installed on the sample outlet pipe.

[0013] Preferably, the second connecting ring is installed on the output end of the sampling valve, and the threaded hole is opened inside the second connecting ring.

[0014] Preferably, the surface of the external threaded ring is threadedly connected to the inner surface of the threaded hole, and the external threaded ring is adhered to the connecting ring 1.

[0015] Preferably, the inner surface of the connecting ring 1 is rotatably connected to the outer surface of the circular ring, and the circular ring is adhered to the detection pipe.

[0016] Preferably, the detection pipe is arranged on the density detector, and the connecting pipe is adhered to the detection pipe.

[0017] Preferably, the connecting pipe is installed on the output end of the flush valve, and the water inlet pipe is installed on the input end of the flush valve.

[0018] Preferably, the solution tank is filled with liquid to be sampled, a sampling bucket is provided inside the liquid to be sampled, and a sampling rope is connected to the upper end of the sampling bucket.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] (1) The liquid density component analysis sampling device is provided with a flushing valve in the cleaning assembly. When the density detector needs to be cleaned, it is only necessary to open the flushing valve and then inject clean water into the water inlet pipe to clean the analysis sampling device. The cleaning is very simple.

[0021] (2) The liquid density component analysis sampling device, by setting the connection relationship between the external threaded ring and the threaded hole in the sampling and analysis component, can quickly disassemble the analysis sampling device when the analysis sampling device is not in use, thereby avoiding accidental contact with the analysis sampling device when taking the liquid inside the solution tank, resulting in damage to the analysis sampling device, thereby improving the safety of the analysis sampling device.

[0033] See also Figure 1-5 , the utility model provides a technical solution: a liquid density component analysis sampling device, comprising a solution tank 1;

[0034] The sampling and analysis assembly is arranged on the solution tank 1, and includes a sampling pipe 18, a sampling valve 17, a second connecting ring 16, a threaded hole 15, an external threaded ring 14, a first connecting ring 13, a density detector 12, a circular ring 8 and a detection pipe 9. The sampling pipe 18 is adhered to the solution tank 1, and the sampling valve 17 is installed on the sampling pipe 18;

[0035] The cleaning assembly is arranged on the density detector 12. The cleaning assembly includes a water inlet pipe 5, a flushing valve 6, a connecting pipe 7, a sample outlet pipe 10 and a drain valve 11. The sample outlet pipe 10 is connected to the lower side of the density detector 12, and the drain valve 11 is installed on the sample outlet pipe 10.

[0036] The second connecting ring 16 is installed on the output end of the sampling valve 17 , and the threaded hole 15 is provided inside the second connecting ring 16 .

[0037] The surface of the external threaded ring 14 is threadedly connected to the inner surface of the threaded hole 15, and the external threaded ring 14 is adhered to the connecting ring 13.

[0038] The inner surface of the connecting ring 13 is rotatably connected to the outer surface of the circular ring 8, and the circular ring 8 is adhered to the detection pipe 9.

[0039] The detection pipe 9 is arranged on the density detector 12 , and the connecting pipe 7 is adhered to the detection pipe 9 .

[0040] The connecting pipe 7 is installed on the output end of the flushing valve 6 , and the water inlet pipe 5 is installed on the input end of the flushing valve 6 .

[0041] The solution tank 1 contains a liquid 4 to be sampled, and a sampling barrel 2 is located inside the liquid 4 to be sampled. The upper end of the sampling barrel 2 is connected to a sampling rope 3.

[0042] During sampling and testing at this stage, first, the sampling bucket 2 is placed inside the liquid to be sampled 4, and the sampling rope 3 is pulled to take out the liquid to be sampled 4 inside the solution tank 1, and then the density component of the liquid to be sampled 4 is tested.

[0043] When sampling is required in the utility model, first, the connecting ring 13 is rotated by an external force, and the rotation of the connecting ring 13 drives the external threaded ring 14 to rotate and be installed inside the threaded hole 15.

[0044] Secondly, close the flushing valve 6 and the drain valve 11, and then start the sampling valve 17. The liquid to be sampled 4 inside the starting solution tank 1 of the sampling valve 17 flows into the detection pipe 9 through the sampling pipe 18, and finally enters the interior of the density detector 12. After a certain amount of liquid to be sampled 4 enters, the sampling valve 17 is closed to stop sampling, and the density detector 12 is started to analyze the composition of the liquid to be sampled 4.

[0045] When it is necessary to clean the density detector 12, first, open the drain valve 11, and let the liquid to be sampled 4 inside the density detector 12 flow out of the interior of the density detector 12 through the sample outlet pipe 10. After the liquid to be sampled 4 flows out of the interior of the density detector 12, open the flushing valve 6 and inject water into the water inlet pipe 5. The water flows through the connecting pipe 7 to the detection pipe 9, and then to the density detector 12, and finally flows out through the sample outlet pipe 10, thereby cleaning the analysis and sampling device.

[0046] By setting the flushing valve 6 in the cleaning assembly, when the density detector 12 needs to be cleaned, it is only necessary to open the flushing valve 6 and then inject clean water into the water inlet pipe 5 to clean the analysis and sampling device, which is very easy to clean.

[0047] By setting the connection relationship between the external threaded ring 14 and the threaded hole 15 in the sampling and analysis component, the analysis and sampling device can be quickly disassembled when not in use, avoiding accidental contact with the analysis and sampling device when taking out the liquid inside the solution tank 1, thereby improving the safety of the analysis and sampling device.

[0048] Working principle:

[0049] When sampling is required in the utility model, first, the connecting ring 13 is rotated by an external force, and the rotation of the connecting ring 13 drives the external threaded ring 14 to rotate and be installed inside the threaded hole 15.

[0050] Secondly, close the flushing valve 6 and the drain valve 11, and then start the sampling valve 17. The liquid to be sampled 4 inside the starting solution tank 1 of the sampling valve 17 flows into the detection pipe 9 through the sampling pipe 18, and finally enters the interior of the density detector 12. After a certain amount of liquid to be sampled 4 enters, close the sampling valve 17 to stop sampling and start the density detector 12.

[0051] When the density detector 12 needs to be cleaned, first, open the drain valve 11, and let the liquid to be sampled 4 inside the density detector 12 flow out of the density detector 12 through the sample outlet pipe 10. After the liquid to be sampled 4 flows out of the density detector 12, open the flushing valve 6 and inject water into the water inlet pipe 5. The water flows through the connecting pipe 7 to the detection pipe 9, and then to the density detector 12, and finally flows out through the sample outlet pipe 10.

[0052] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
