Description

Technical Field

[0001] This utility model relates to a sampler for macromonomers in water-reducing agents. Background Technology

[0002] Because the water-reducing agent has a high solidification point, after each reaction and post-processing sampling, the residual material will cause the sampling valve and pipeline to condense. Steam is needed to bake the pipeline before it can be used again. This increases the amount of steam used, reduces work efficiency, increases labor costs, and also poses safety risks. Utility Model Content

[0003] The purpose of this invention is to provide a sampler for macromonomers in water-reducing agents, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a sampler for macromonomers of water-reducing agents, including a pump outlet pipeline connected to a pump, characterized in that: it also includes a sampling pipeline connected to the pump outlet pipeline, the sampling pipeline is equipped with a heat-insulating ball valve, and heat-tracing pipes are respectively closely attached to the sampling pipeline and the pump outlet pipeline, the heat-tracing pipes are connected to the heat-insulating ball valve, and the outer sides of the heat-tracing pipes and the pump outlet pipeline are provided with heat insulation layers.

[0005] Preferably, there are two heat tracing pipes, namely a first heat tracing pipe and a second heat tracing pipe. One end of the first heat tracing pipe is located at the upper part of the pump outlet pipeline, and the end of the first heat tracing pipe is connected to the interface end of the heat-insulating ball valve. One end of the second heat tracing pipe is connected to the outlet end of the heat-insulating ball valve, and the middle part of the second heat tracing pipe is wrapped around the outside of the sampling pipeline. The other end of the second heat tracing pipe is pulled to the lower part of the pump outlet pipeline.

[0006] Preferably, the second heat tracing pipe is spirally wound around the outside of the sampling pipe.

[0007] Preferably, the heat tracing pipe is a flexible metal hose.

[0008] Preferably, the insulation layer is insulation cotton.

[0009] Preferably, the outer side of the insulation layer of the pump outlet pipeline is provided with an aluminum cladding.

[0010] Preferably, both ends of the insulated ball valve are connected to the sampling pipeline via flanges.

[0011] Preferably, the sampling pipeline includes a first sampling tube and a second sampling tube connected to the tail of the first sampling tube. The first sampling tube is inclined downward at a 45-degree angle to the material tube, and the opening of the second sampling tube faces downward.

[0012] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages:

[0013] This utility model provides a sampler for large monomers of water-reducing agents. The original sampling valve is replaced with an insulated ball valve with a feedback signal. Heat tracing pipes are designed on the pump outlet pipeline, the insulated ball valve, and the sampling pipeline. These pipes heat the pump outlet pipeline (using 3 barg steam) upstream of the insulated ball valve, then connect to the insulated ball valve, and continue to the sampling pipeline downstream of the insulated ball valve. Finally, they return to the pump outlet pipeline upstream of the insulated ball valve. This ensures effective heat tracing of the pump outlet pipeline, sampling pipeline, and insulated ball valve, maintaining a temperature sufficient to keep residual materials in a liquid state. This prevents condensation of residual materials within the sampling valve and pipeline, reduces steam consumption, and lowers labor intensity. Attached Figure Description

[0022] Example

[0023] refer to Figure 1 , Figure 2 and Figure 3 A sampler for macromonomers of water-reducing agents includes a pump outlet pipeline 1 connected to a pump and a sampling pipeline 2 connected to the pump outlet pipeline 1. The sampling pipeline 2 is equipped with an insulated ball valve 3. The sampling pipeline 2 and the pump outlet pipeline 1 are respectively provided with heat tracing pipes that are tightly attached to the sampling pipeline 2 and the pump outlet pipeline 1. The heat tracing pipes are metal flexible hoses and are connected to the insulated ball valve 3. The outer sides of the heat tracing pipes and the pump outlet pipeline 1 are provided with heat insulation layers.

[0024] There are two heat tracing pipes: a first heat tracing pipe 41 and a second heat tracing pipe 42. One end of the first heat tracing pipe 41 is located at the upper part of the pump outlet pipeline 1, and the end of the first heat tracing pipe 41 is connected to the interface end 31 of the heat-insulating ball valve 3. One end of the second heat tracing pipe 42 is connected to the outlet end 32 of the heat-insulating ball valve 3, and the middle part of the second heat tracing pipe 42 is wrapped around the outside of the sampling pipeline 2. The other end of the second heat tracing pipe 42 is pulled to the lower part of the pump outlet pipeline 1.

[0025] The second heat tracing pipe 42 is spirally wound around the outside of the sampling pipe 2. This structure increases the contact area between the heat tracing pipe and the sampling pipe 2, thus improving the heat tracing effect.

[0026] The insulation layer is made of insulating cotton; the outer side of the insulation layer of pump outlet pipeline 1 is covered with aluminum foil. With this structure, the insulation layer can insulate the heat tracing pipeline and pump outlet pipeline 1, ensuring heat conduction and preventing burns.

[0027] Both ends of the insulated ball valve 3 are connected to the sampling pipeline 2 via flanges 5. This structure facilitates the disassembly and installation of the insulated ball valve 3.

[0028] The sampling line 2 includes a first sampling tube 21 and a second sampling tube 22 connected to the tail of the first sampling tube 21. The first sampling tube 21 is inclined downward at a 45-degree angle to the material tube, and the opening of the second sampling tube 22 faces downward. With this structure, the first sampling tube 21 is inclined at a 45-degree angle to the material tube, which can prevent material accumulation.

[0029] It also includes a DCS system (not shown in the figure) connected to the insulated ball valve 3; wherein, the DCS system is used to control the opening degree of the insulated ball valve 3, thereby ensuring that the insulated ball valve 3 is in the closed state after sampling, preventing the insulated ball valve 3 from being not closed completely during sampling, which would lead to material leakage.

[0030] During operation, the first heat tracing pipe 41 heats the pump outlet pipe 1 at the front end of the insulated ball valve 3 (using 3 barg steam), and then connects to the interface end 31 of the insulated ball valve 3. The second heat tracing pipe 42 is led out from the outlet end 32 of the insulated ball valve 3 and traces to the first sampling pipe 21 at the rear end of the insulated ball valve 3. Finally, it returns to the pump outlet pipe 1 at the front end of the insulated ball valve 3. This ensures that the pump outlet pipe 1, the sampling pipe 2, and the insulated ball valve 3 can be effectively heated. The temperature is sufficient to keep the internal residual material in a liquid state, thereby preventing the residual material from condensing in the sampling valve and pipe, reducing steam consumption, and reducing labor intensity.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
