Description

An anti-clogging device for coal-water slurry sampling points Technical Field

[0001] This application relates to the field of coal-water slurry production testing, and in particular to an anti-clogging device for coal-water slurry sampling points. Background Technology

[0002] Currently, in the coal-to-methanol process, sampling and testing of coal-water slurry is a crucial means to ensure its fluidity and quality. Commonly used coal-water slurry sampling points are prone to clogging. Structurally, these points suffer from technical defects such as the accumulation of particulate impurities in the slurry at the sampling port and blockages inside the sampling pipe due to coal slurry sedimentation. These defects prevent normal sampling, affecting the timeliness and accuracy of test results, and consequently negatively impacting production control. Summary of the Invention

[0003] To address the aforementioned issues, this application provides an anti-clogging device for coal-water slurry sampling points, which can prevent clogging at the sampling points.

[0004] To achieve the objectives of this application, the following technical solution is provided:

[0005] This application provides an anti-clogging device for a coal-water slurry sampling point, including a coal-water slurry main pipe. The bottom end of the coal-water slurry main pipe is connected to a flushing water pipe. The flushing water pipe includes an outer pipe and an inner pipe. The inner pipe is installed inside the outer pipe, and a fluid cavity is provided between the outer pipe and the inner pipe. A plurality of nozzles are connected to the inner wall of the inner pipe. One end of the plurality of nozzles is connected to the inside of the fluid cavity. A water inlet is opened on the outer wall of the outer pipe. One end of the water inlet is connected to a water inlet pipe. The bottom end of the outer wall of the inner pipe is connected to a water outlet pipe. One end of the water outlet pipe extends to the outside of the outer pipe and is connected to a one-way valve mechanism.

[0006] In one possible implementation, the water inlet pipe includes a horizontal pipe, one end of which is connected to a flushing water pressure controller, and one end of which is connected to a flushing water control valve.

[0007] The beneficial effect of adopting the above-mentioned further solution is that the flushing water pressure controller can adjust the pressure of the flushing water to keep it within a suitable range. The flushing water control valve can control the on / off of the flushing water. The two work together to accurately control the pressure and flow rate of the flushing water according to the actual situation of the coal-water slurry main pipe, ensuring the flushing effect while avoiding damage to the pipeline due to excessive pressure.

[0008] In one possible implementation, the flushing water pressure controller is configured as an adjustable pressure reducing valve, and the flushing water control valve is configured as an electromagnetic control valve.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, by using an adjustable pressure reducing valve as the flushing water pressure controller, the flushing water pressure can be flexibly adjusted according to actual needs to adapt to the flushing requirements of water-coal slurry under different working conditions. The electromagnetic control valve, as the flushing water control valve, can quickly respond to control signals and accurately control the on / off time of the flushing water, achieving automated control.

[0010] In one possible implementation, the one-way valve mechanism includes a valve body, an internal water-passing plate installed on one side of the valve body, a spring connected to one side of the water-passing plate, and a sealing ball connected to one end of the spring.

[0011] The beneficial effect of adopting the above-mentioned further solution is that when flushing water flows into the valve body from the outlet pipe, the water pressure pushes the sealing ball to compress the spring, causing the water to flow out through the water passage plate. When the flushing water stops flowing out, the spring pushes the sealing ball to block the conical wall inside the valve body, thus sealing the outlet pipe and preventing air from entering the pipe.

[0012] In one possible implementation, the inner wall of the valve body is provided with a conical wall, one side of which contacts the sealing ball.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by setting the conical wall, the diameter of the end near the water-passing plate is increased, thereby providing flow space for flushing water. At the same time, the diameter of the end away from the water-passing plate is reduced, thereby facilitating the sealing ball to seal the valve body.

[0014] In one possible implementation, the coal-water slurry main pipe includes a pipe body, the bottom surface of which has an interface, the interior of which communicates with the top of the inner pipe.

[0015] The beneficial effect of adopting the above-mentioned further scheme is that it provides a stable connection channel for the flow of coal-water slurry. This connection method ensures that the coal-water slurry can be transferred from the main pipe to the inside of the flushing water pipe until it is discharged by the sampling valve.

[0016] In one possible implementation, a sampling valve is provided at the bottom end of the flushing water pipe, and the top end of the sampling valve is connected to the bottom end of the inner pipe.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, after rinsing is completed, the sampling valve can be easily opened for water-coal slurry sampling. The sampling valve can effectively control the sampling process, prevent water-coal slurry leakage when not sampling, and also facilitate operators to perform sampling operations as needed.

[0018] In one possible implementation, the orientation of all of the nozzles remains tilted downwards.

[0019] The beneficial effect of adopting the above-mentioned further scheme is that by spraying the flushing water downwards at a certain angle, the sampling point area at the bottom of the coal-water slurry main pipe can be better flushed. The downward-sloping nozzle can utilize gravity to enhance the flushing force of the flushing water on the coal-water slurry, loosening and flushing away the coal-water slurry accumulated at the bottom, more effectively preventing sampling point blockage, and improving the flushing efficiency and effect of the anti-clogging device.

[0020] In one possible implementation, one end of the outlet pipe is connected to a baffle, which is located inside the inner pipe.

[0021] The beneficial effect of adopting the above-mentioned further solution is that by connecting the baffle, it is easy to block one end of the water outlet pipe, thereby preventing the coal-water slurry flowing inside the inner pipe from entering the water outlet pipe and ensuring that the sampling valve can smoothly discharge the coal-water slurry.

[0022] This anti-clogging device for coal-water slurry sampling points, through the coordinated use of a flushing water pipe, an outlet pipe, and a one-way valve mechanism, can periodically flush the sampling pipeline, effectively preventing the coal-water slurry from depositing in the short-circuit joint and at the sampling port, thus improving sampling efficiency. The fluid cavity between the outer and inner pipes of the flushing water pipe, combined with multiple nozzles, allows the flushing water flowing in from the inlet to be evenly sprayed into the coal-water slurry main pipe. This effectively flushes the coal-water slurry near the sampling point, preventing it from accumulating, drying, and causing blockages, ensuring smooth coal-water slurry sampling. The inner pipe connects to the outlet pipe and the one-way valve mechanism, allowing for timely discharge of flushed water and preventing accumulation within the device. Attached Figure Description

[0032] Example 1

[0033] Figures 1-5 illustrate an anti-clogging device for a coal-water slurry sampling point provided in an embodiment of this application. The device includes a coal-water slurry main pipe 100, with a flushing water pipe 200 connected to the bottom end of the main pipe 100. The flushing water pipe 200 includes an outer pipe 2001 and an inner pipe 2002. The inner pipe 2002 is installed inside the outer pipe 2001, and a fluid cavity 2003 is provided between the outer pipe 2001 and the inner pipe 2002. A plurality of nozzles 2004 are connected to the inner wall of the inner pipe 2002, with one end of each nozzle 2004 communicating with the interior of the fluid cavity 2003. The outer wall of the inner pipe 2001 has an inlet 2005, one end of which is connected to an inlet pipe 400. The bottom of the outer wall of the inner pipe 2002 is connected to an outlet pipe 500, one end of which extends to the outside of the outer pipe 2001 and is connected to a one-way valve mechanism 600. The fluid cavity 2003 between the outer pipe 2001 and the inner pipe 2002 of the flushing water pipe 200, in conjunction with multiple nozzles 2004, allows the flushing water flowing in from the inlet 2005 to be evenly sprayed into the interior of the coal-water slurry main pipe 100 through the nozzles 2004. This effectively flushes the coal-water slurry near the sampling point, preventing it from accumulating and drying at the sampling point and causing blockages, thus ensuring the smooth progress of coal-water slurry sampling. The inner pipe 2002, connected to the outlet pipe 500 and the one-way valve mechanism 600, can promptly discharge the flushed water, preventing its accumulation inside the device.

[0034] In one possible implementation, as an embodiment of this utility model, the water inlet pipe 400 further includes a horizontal pipe 4001. One end of the horizontal pipe 4001 is connected to a flushing water pressure controller 4002, and the other end of the flushing water pressure controller 4002 is connected to a flushing water control valve 4003. The flushing water pressure controller 4002 can adjust the pressure of the flushing water to keep it within a suitable range. The flushing water control valve 4003 can control the on / off state of the flushing water. The two work together to accurately control the pressure and flow rate of the flushing water according to the actual situation of the coal-water slurry main pipe 100, ensuring the flushing effect while avoiding damage to the pipe due to excessive pressure. The flushing water pressure controller 4002 is an adjustable pressure reducing valve, and the flushing water control valve 4003 is an electromagnetic control valve. Using an adjustable pressure reducing valve as the flushing water pressure controller 4002 allows for flexible adjustment of the flushing water pressure according to actual needs, adapting to the flushing requirements of coal-water slurry under different working conditions. The electromagnetic control valve as the flushing water control valve 4003 can quickly respond to control signals and accurately control the on / off time of the flushing water, realizing automated control.

[0035] As an embodiment of this utility model, the one-way valve mechanism 600 further includes a valve body 6001. A water-passing plate 6002 is installed on one side of the interior of the valve body 6001. A spring 6003 is connected to one side of the water-passing plate 6002. A sealing ball 6004 is connected to one end of the spring 6003. When flushing water flows into the valve body 6001 from the water outlet pipe 500, the water pressure pushes the sealing ball 6004 to compress the spring 6003, causing the water to flow out through the water-passing plate 6002. When the flushing water stops flowing out, the spring 6003 pushes the sealing ball 6004 to block the conical wall of the inner wall of the valve body 6001, thus sealing the water outlet pipe 500. This helps prevent air from entering the pipe. The inner wall of the valve body 6001 is provided with a conical wall, one side of which contacts the sealing ball 6004. The conical wall increases the diameter of the end near the water-passing plate 6002, providing flow space for the flushing water. At the same time, it reduces the diameter of the end away from the water-passing plate 6002, making it easier for the sealing ball 6004 to seal the valve body 6001.

[0036] As one embodiment of this utility model, the coal-water slurry main pipe 100 further includes a pipe body 1001. An interface 1002 is provided on the bottom surface of the pipe body 1001. The interior of the interface 1002 communicates with the top end of the inner pipe 2002, providing a stable connection channel for the flow of coal-water slurry. This connection method ensures that the coal-water slurry can be transferred from the main pipe to the flushing water pipe 200 until it is discharged by the sampling valve 300. The bottom end of the flushing water pipe 200 is equipped with a sampling valve 300, the top end of which communicates with the bottom end of the inner pipe 2002. After flushing is completed, the sampling valve 300 can be easily opened to sample the coal-water slurry. The sampling valve 300 can effectively control the sampling process, preventing leakage of coal-water slurry when not sampling, and also facilitating sampling operations by operators as needed.

[0037] In one embodiment of this utility model, the nozzles 2004 are all tilted downwards, so that the flushing water is sprayed downwards at a certain angle, which can better flush the sampling point area at the bottom of the coal-water slurry main pipe 100. The downward tilting nozzles can utilize gravity to enhance the flushing force of the flushing water on the coal-water slurry, loosening and washing away the coal-water slurry accumulated at the bottom, more effectively preventing the sampling point from clogging, and improving the flushing efficiency and effect of the anti-clogging device.

[0038] As an embodiment of this utility model, a baffle is further connected to one end of the water outlet pipe 500. The baffle is located inside the inner pipe 2002. By connecting and using the baffle, it is convenient to block one end of the water outlet pipe 500, thereby preventing the coal-water slurry flowing inside the inner pipe 2002 from entering the water outlet pipe 500, and ensuring that the sampling valve 300 can smoothly discharge the coal-water slurry.

[0039] Specifically, the working principle of this anti-clogging device for coal-water slurry sampling points is as follows: During use, the coal-water slurry flows within the pipe body 1001 of the coal-water slurry main pipe 100, and its bottom interface 1002 is connected to the top of the inner pipe 2002 of the flushing water pipe 200. When it is necessary to prevent clogging of the sampling point, the horizontal pipe 4001 of the inlet pipe 400 introduces flushing water, and the flushing water pressure controller 4002 adjusts the pressure. Specifically, the flushing water pressure controller 4002 is an adjustable pressure reducing valve, and the flushing water control valve 4003 controls the on / off state. Specifically, the flushing water control valve 4003 is an electromagnetic control valve, so that flushing water with appropriate pressure and flow rate flows from the inlet 2005 of the outer pipe 2001 into the fluid cavity 2003, and then is sprayed into the interior of the coal-water slurry main pipe 100 through several downward-sloping nozzles 2004. The gravity enhances the flushing force, effectively flushing the coal-water slurry near the sampling point and preventing accumulation and clogging. After rinsing, the water flows into the one-way valve mechanism 600 through the outlet pipe 500, which is connected to the bottom of the outer wall of the inner pipe 2002. The water pressure pushes the sealing ball 6004 to compress the spring 6003, and the water flows out through the water plate 6002. When the rinsing water stops, the spring 6003 pushes the sealing ball 6004 to block the conical wall inside the valve body 6001, preventing air from entering. After rinsing is completed, the sampling valve 300, which is connected to the bottom of the rinsing water pipe 200 and the bottom of the inner pipe 2002, is opened to sample the coal-water slurry. At the same time, the baffle connected to one end of the outlet pipe 500 inside the inner pipe 2002 prevents the coal-water slurry from flowing into the outlet pipe 500, ensuring that the sampling valve 300 can smoothly discharge the coal-water slurry.

[0040] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. This application is not limited to the exact structures described above and illustrated in the accompanying drawings, and it should not be considered that the specific implementation of this application is limited to these descriptions. For those skilled in the art, various changes and modifications made without departing from the concept of this application should be considered to fall within the protection scope of this application.
