Abstract
Description
Technical Field
[0001] This application relates to the field of chemical sampling technology, specifically to a buffer pipeline for raw material sampling and preparation. Background Technology
[0002] In the chemical industry, a long buffer pipeline is required between chemical raw material storage tanks and application sites because the flow rate of samples is relatively high, while the required flow rate of raw materials at the application site is relatively low. Therefore, this long buffer pipeline is needed to slow down the delivery of raw materials. Excessive length of the buffer pipeline increases the material usage, thereby increasing production costs and reducing the economic efficiency of chemical production. In view of this, this utility model provides a buffer pipeline for raw material sampling and preparation. Summary of the Invention
[0003] This utility model provides a buffer pipeline for raw material sampling and processing to solve the problem of insufficient buffering effect of existing chemical buffer pipelines.
[0004] This utility model discloses a raw material sampling and processing buffer pipeline, which is set between the raw material outlet end and the raw material usage end. It includes a main pipeline and two buffer pipelines of equal length. A flow divider is included at the connection between the main pipeline and the first buffer pipeline. The inlets of the first buffer pipeline and the second buffer pipeline are respectively located at different positions on the main pipeline. The outlets of the first buffer pipeline and the second buffer pipeline are staggered on the main pipeline. The flow divider is configured to split half of the flow of the main pipeline into the first buffer pipeline or the second buffer pipeline.
[0005] In this invention, a buffer pipeline is used in raw material collection and processing, specifically a pipeline that transports raw materials from the outlet to the user. It comprises two buffer pipelines of equal length. A diverter is installed in the main pipeline to separately divert half of the raw material flow in the main pipeline to the first buffer pipeline, allowing the other half to automatically enter the second buffer pipeline. In other words, the flow in the main pipeline is first divided into two parts, which are then buffered and slowed down in the two buffer pipelines. Because the first and second buffer pipelines are independent and their inlets are staggered at different locations on the main pipeline, the two buffer pipelines work together to slow down the flow entering the main pipeline twice, thus achieving a sufficient buffering effect. The use of two buffer pipelines not only shortens the length of the original main pipeline for automatic speed reduction, saving pipeline space, but also improves the economic efficiency of chemical production.
[0006] Optionally, the first buffer pipe and the second buffer pipe are arc-shaped pipes or irregularly shaped pipes including at least one C-shaped bend.
[0007] In this design, the first and second buffer pipelines are configured as arc-shaped or irregularly shaped pipe structures containing at least one C-bend to reduce the footprint of the buffer pipelines and the overall pipeline footprint, thereby further improving the economic efficiency of the pipeline design.
[0008] Optionally, the main pipeline, the first buffer pipeline, and the second buffer pipeline all include insertion flow meters.
[0009] In this design, insertion flow meters are installed in the main pipeline and two buffer pipelines to detect the flow rate of raw materials in different pipelines, thereby visualizing the pipeline flow. In addition, the pipeline monitoring can also diagnose the pipeline patency based on the flow parameters of different pipelines, thereby determining whether the pipeline needs maintenance or cleaning, thus providing convenience for pipeline monitoring and pipeline cleaning.
[0010] Optionally, the inlets of both the first buffer pipeline and the second buffer pipeline include one-way valves.
[0011] In this design, one-way valves are installed at the inlets of the first and second buffer pipelines to prevent the raw material from flowing back into the buffer pipelines.
[0012] Optionally, the main pipeline may also include a pump body.
[0013] In this design, a pump body is installed on the main pipeline to facilitate automatic extraction of raw materials from the outlet, and also to facilitate control of the head of the main pipeline.
[0014] Optionally, both the first buffer line and the second buffer line include a damper at their front ends.
[0015] In this design, the damper is used to control the flow rate of the first and second buffer pipes, and at the same time, to handle any foam or bubbles that may be generated inside the pipes.
[0016] Optionally, a cleaning pipeline is also included, which is configured to be connected in parallel with the first buffer pipeline and the second buffer pipeline, respectively.
[0017] Because the flow rate of raw materials decreases in the downstream section of the buffer pipeline, some easily settled components in the raw materials are more likely to gradually adhere to the pipe wall. Over time, the buffer pipeline will be blocked by these settled components. Therefore, this design includes a cleaning pipeline for convenient periodic cleaning of the first and second buffer pipelines. When cleaning is not required, the cleaning pipeline is connected in parallel with the buffer pipeline and left idle. When cleaning is required, both buffer pipelines can be closed, or one of the buffer pipelines can be closed to control the continued operation of a single buffer pipeline.
[0018] Optionally, the cleaning pipeline includes: an inlet pipe, a control valve, an outlet pipe, a clean water tank, and a wastewater tank. The inlet pipe and the outlet pipe are both used to connect to the first buffer pipeline and the second buffer pipeline at a preset angle. The inlet end of the inlet pipe is connected to the clean water tank, and the outlet end of the outlet pipe is connected to the wastewater tank. The control valve is respectively located on the inlet pipe and the outlet pipe. The flow direction of the cleaning pipeline is opposite to that of the first buffer pipeline and the second buffer pipeline.
[0019] This design proposes a cleaning pipeline system comprising an inlet pipe, an outlet pipe, a clean water tank, and a wastewater tank. Liquid from the clean water tank enters the buffer pipeline, cleans the buffer pipeline, and then exits through the outlet pipe into the wastewater tank. The cleaning fluid in the cleaning pipeline flows in the opposite direction to the raw material flow in the original buffer pipeline. This reverse flow effectively dissipates and impacts impurities deposited and adhering to the pipe walls, improving the cleaning effect.
[0020] Optionally, the liquid outlet pipe includes a section of drain pipe, and the drain pipe is equipped with a drain valve.
[0021] In this design, a drain pipe is installed to discharge the cleaned particulate impurities from the drain valve, preventing impurities from entering the sewage tank and burdening the sewage treatment process inside the tank, thus further improving the practicality of the cleaning pipeline.
[0022] Optionally, the drain pipe is a V-shaped pipe, and the drain valve is connected to the bottom end of the drain pipe.
[0023] In this design, a V-shaped drain pipe is installed, allowing impurities to settle at the bottom of the V-shaped pipe by their own gravity, which facilitates drainage and also helps filter impurities.
[0024] The beneficial effects of this utility model are:
[0025] The installation of a double-buffered pipeline allows the material in the main pipeline to be buffered and slowed down twice, improving buffering efficiency, saving the floor space of the buffer pipeline, and enhancing the practicality of buffering and slowing down and the economy of chemical production.

[0034] The technical solutions in the embodiments of the application will now be clearly and completely described with reference to the accompanying drawings. Furthermore, the phrases "in one embodiment" or "in one embodiment" appearing throughout this specification do not necessarily refer to the same embodiment. Moreover, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.
[0035] In the chemical industry, a long buffer pipeline is required between chemical raw material storage tanks and application sites because the flow rate of samples is relatively high, while the required flow rate of raw materials at the application site is relatively low. Therefore, this long buffer pipeline is needed to slow down the delivery of raw materials. Excessive length of the buffer pipeline increases the material usage, thereby increasing production costs and reducing the economic efficiency of chemical production. In view of this, this utility model provides a buffer pipeline for raw material sampling and preparation.
[0036] The present application will now be described in detail with reference to the accompanying drawings and embodiments.
[0037] This utility model discloses a buffer pipeline for raw material sampling and processing, which is set between the raw material outlet end and the raw material usage end. It includes a main pipeline 1 and two buffer pipelines of equal length. A diverter is included at the connection between the main pipeline 1 and the first buffer pipeline 2. The inlets of the first buffer pipeline 2 and the second buffer pipeline 3 are respectively set at different positions on the main pipeline 1. The outlets of the first buffer pipeline 2 and the second buffer pipeline 3 are staggered on the main pipeline 1. The diverter is configured to split half of the flow of the main pipeline 1 into the first buffer pipeline 2 or the second buffer pipeline 3.
[0038] like Figure 1 As shown, in this utility model, the buffer pipeline is used in the raw material collection and processing, that is, the pipeline that transports the raw material from the raw material outlet to the raw material usage end. Specifically, it includes two buffer pipelines of equal length, and the flow direction of the main pipeline 1 is as follows: Figure 1As indicated by the white arrow in the middle. A distributor is installed in the main pipeline 1 to divert half of the raw material flow from the main pipeline 1 to the first buffer pipeline 2 (e.g., Figure 1 (As indicated by the black arrow in the middle), causing the other half to automatically enter the second buffer pipe 3 (such as...). Figure 1 (As indicated by the black arrow in the middle), the flow rate of main pipeline 1 is first divided into two parts, which are then buffered and slowed down in two buffer pipelines. Because the first buffer pipeline 2 and the second buffer pipeline 3 are independent of each other, and their inlets are staggered at different locations on main pipeline 1, the flow rate entering main pipeline 1 is slowed down twice through the cooperation of the two buffer pipelines, thus achieving a sufficient buffering effect. Setting up two buffer pipelines not only shortens the original pipe length for automatic speed reduction on main pipeline 1, saving pipework, but also improves the economics of chemical production.
[0039] The aforementioned first buffer pipe 2 and second buffer pipe 3 are arc-shaped pipes or irregularly shaped pipes including at least one C-shaped bend.
[0040] In this design, the first buffer pipe 2 and the second buffer pipe 3 are set as arc-shaped or irregular pipe structures containing at least one C-bend. On the one hand, the arc-shaped or C-bend structure can change the conveying direction of the raw materials in the pipe multiple times and be buffered multiple times by the inner wall of the pipe, which is conducive to sufficient speed reduction. On the other hand, this type of buffer pipe can reduce the footprint of the buffer pipe and the footprint of the entire pipeline, further improving the economy of the pipeline design.
[0041] Alternatively, the first buffer pipe 2 and the second buffer pipe 3 mentioned above can be configured as an arc-shaped structure and a C-shaped bend structure respectively, or the two structures can be the same and belong to one of the two structures mentioned above. This embodiment does not impose specific restrictions on this. Figure 1 The above is just one of the three options mentioned above.
[0042] In addition, in specific implementation, the main pipeline 1, the first buffer pipeline 2, and the second buffer pipeline 3 can all be equipped with insertion flow meters 4. Because the insertion flow meters 4 are installed in the main pipeline 1 and the two buffer pipelines, the flow rate of the raw materials in different pipelines can be detected, so as to visualize the pipeline flow. In addition, in pipeline monitoring, the unobstructed condition of the pipeline can be diagnosed based on the flow parameters of different pipelines, thereby determining whether the pipeline needs maintenance or cleaning, thus providing convenience for pipeline monitoring and pipeline cleaning.
[0043] In some embodiments, the feed inlets of the aforementioned first buffer pipeline 2 and second buffer pipeline 3 both include a one-way valve 5.
[0044] In this embodiment, a one-way valve 5 is installed at the inlet of the first buffer pipe 2 and the second buffer pipe 3 to prevent the backflow of raw materials in the buffer pipe of the first buffer pipe or the second buffer pipe, that is, to control the unidirectional flow of materials in the pipe.
[0045] Alternatively, a pump body for suction of materials can be installed on the main pipeline 1. In this embodiment, a pump body is installed on the main pipeline 1 to facilitate automatic extraction of raw materials from the outlet. Furthermore, when it is necessary to control the head of the outlet material, the head of the main pipeline 1 can be controlled by adjusting the output parameters of the pump. Since the corresponding head may vary under different conveying environments, a pump body is installed to meet actual needs. It should be noted that this invention does not specifically limit the pump body; a pump body with an appropriate structure can be selected according to the type of raw material being conveyed.
[0046] In other embodiments, in order to improve the control of the raw material flow rate by the aforementioned first buffer pipeline 2 and second buffer pipeline 3, a damper 6 is included at the front end of both the aforementioned first buffer pipeline 2 and second buffer pipeline 3.
[0047] In this embodiment, the damper 6 functions to control the flow rate of the first buffer pipe 2 and the second buffer pipe 3. When raw material flows into the buffer pipe at a certain speed and passes through the damper 6, the structure of the damper 6 causes the raw material to collide with it, thereby reducing the flow rate of the raw material. In addition, the damper 6 can also break up any foam or bubbles that may be generated in the buffer pipe, preventing these bubbles from affecting the pressure of the conveyed material in the pipe.
[0048] What can be implemented is that the aforementioned damper 6 can be as follows: Figure 2 , Figure 3 , Figure 4 The three structures shown can be connected to the first buffer pipe 2 and the second buffer pipe 3 by flange connection or by direct insertion from the outside of the pipe, with a sealing structure. This embodiment does not impose specific restrictions on this.
[0049] In some embodiments, the buffer pipeline disclosed in this utility model may further include a cleaning pipeline 7, which is configured to be connected in parallel with the first buffer pipeline 2 and the second buffer pipeline 3, respectively. Because the flow rate of the raw material in the later section of the buffer pipeline decreases, some easily settled components in the raw material are more likely to gradually adhere to the pipe wall. Over time, the buffer pipeline will be blocked by these settled components. Therefore, the cleaning pipeline 7 is provided in this design to facilitate the periodic cleaning of the first buffer pipeline 2 and the second buffer pipeline 3. When cleaning is not required, the cleaning pipeline 7 is connected in parallel with the buffer pipeline and is left stationary. When cleaning is required, both buffer pipelines can be closed, or one of the buffer pipelines can be closed to control the continued operation of a single buffer pipeline.
[0050] Specifically, the aforementioned cleaning pipeline 7 includes: an inlet pipe 71, a control valve, an outlet pipe 72, a clean water tank, and a wastewater tank. The inlet pipe 71 and the outlet pipe 72 are both used to connect with the first buffer pipeline 2 and the second buffer pipeline 3 at a preset angle. The inlet end of the inlet pipe 71 is connected to the clean water tank, and the outlet end of the outlet pipe 72 is connected to the wastewater tank. The control valves are respectively installed on the inlet pipe 71 and the outlet pipe 72. The flow direction of the cleaning pipeline 7 is opposite to the flow direction of the first buffer pipeline 2 and the second buffer pipeline 3.
[0051] like Figure 5 As shown, where Figure 5 The arrangement of the cleaning pipeline 7 is illustrated using only the second buffer pipeline 3 as an example. In this embodiment, a cleaning pipeline 7 is proposed, comprising an inlet pipe 71, an outlet pipe 72, a clean water tank, and a wastewater tank. This allows liquid from the clean water tank to enter the buffer pipeline, and after flushing and cleaning the buffer pipeline, it is discharged from the outlet pipe 72 into the wastewater tank. The cleaning fluid flow direction of the cleaning pipeline 7 is opposite to the raw material flow direction of the original buffer pipeline, such as... Figure 5 The direction indicated by the black arrow in the middle indicates the direction of flow in the cleaning pipeline. Figure 5 The white arrows indicate the flow direction of the raw material in the main pipeline 1. Because the opposite flow rate can effectively impact impurities deposited and attached to the pipe wall, it can improve the cleaning effect. The inlet pipe 71 and outlet pipe 72 can be connected perpendicularly to or cross-connected to the main pipeline 1; this embodiment does not impose specific limitations on this.
[0052] In some embodiments, the aforementioned outlet pipe 72 further includes a drain pipe 8, on which a drain valve 9 is provided.
[0053] In this embodiment, a drain pipe 8 is provided that intersects with the outlet pipe 72, and the drain pipe 8 is positioned relatively low relative to the main pipeline 1, which facilitates the sedimentation of impurities in the pipe within the drain pipe 8. When impurities in the pipe pass through the drain pipe 8, they settle in the drain pipe 8 under their own weight, and then the sedimented impurities containing particles are discharged from the drain valve 9, preventing impurities from entering the sewage tank and burdening the sewage treatment in the sewage tank, thus further improving the practicality of the cleaning pipeline 7.
[0054] Alternatively, the aforementioned drain pipe 8 can be configured as a V-shaped pipe, with the drain valve 9 connected to the bottom end of the drain pipe 8.
[0055] like Figure 6 As shown, in this design, a V-shaped drain pipe 8 is installed, which helps impurities settle at the bottom of the pipe, facilitating drainage and also aiding in the filtration of impurities. However, it should be noted that the angle of this V-shaped pipe needs to be controlled; an obtuse angle is generally preferred. An angle that is too small can easily cause blockages and is also inconvenient to clean.
[0056] It should be noted that the raw materials or materials mentioned in the foregoing embodiments can be liquid or gaseous, and the specific choice can be made according to the requirements of the actual pipeline. This embodiment does not impose specific limitations on this. In addition, the necessary control valves of the main pipeline 1, the first buffer pipeline 2, the second buffer pipeline 3, and the entire related pipeline system that are not shown in the accompanying drawings can be supplemented according to the actual use process. The accompanying drawings are only for schematic analysis of the principle.
[0057] Finally, all the above embodiments belong to the same inventive concept. The descriptions of each embodiment have different focuses. Where the description of a particular embodiment is not exhaustive, please refer to the descriptions of other embodiments. The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to mutually.
[0058] The above embodiments merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
