Description

Technical Field

[0001] The present invention relates to the technical field of liquid level measurement, and more specifically, to a liquid level measurement anti-blocking device and a use method thereof. Background Art

[0002] The static pressure level gauge measures the liquid level based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. Static pressure level gauges are widely used in industrial production, but when static pressure level gauges are used to measure the level of liquids with a lot of impurities, they are prone to clogging. For example, when the static pressure level gauge is used on a wire production line, the following problems are prone to occur: the sludge in the pool often clogs the pressure-taking hole of the static pressure level gauge, and when the detection is inaccurate, the pool needs to be drained and the sludge needs to be cleaned, but the draining of the pool to clean the sludge must be done when the production is stopped, and it cannot be cleaned during production, so cleaning the sludge will greatly affect production efficiency; there are many pools in the factory area, and static pressure level gauges are used, but the failure rate of clogging the pressure-taking hole is high, which greatly affects production. Therefore, it is necessary to propose an anti-clogging device to solve the above problems. Summary of the invention

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a liquid level measurement anti-clogging device and a method of use, which realizes automatic cleaning of the pressure taking hole of the static pressure level gauge through a vibration motor and a purge ring, thereby improving the accuracy of liquid level measurement, reducing the workload of manual maintenance of the static pressure level gauge, and helping to improve work efficiency.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A liquid level measurement anti-clogging device comprises a vibration module and a purge module, wherein the vibration module comprises a first vibration motor, the first vibration motor is arranged on the side of the probe rod of the static pressure level gauge, and the first vibration motor is 50-70 mm away from the bottom of the probe rod, and the purge module comprises a first purge ring, the first purge ring is arranged on the side of the probe rod and is located 100-150 mm above the first vibration motor; the first purge ring is evenly provided with a plurality of purge rods inclined toward a pressure taking hole at the bottom of the probe rod, and the purge rod is provided with a main purge hole facing the pressure taking hole.

[0006] In one of the embodiments, the first purge ring is also evenly provided with auxiliary purge holes for downward purge, and the purge direction of the auxiliary purge holes is parallel to the probe rod.

[0007] In one of the embodiments, the vibration module further includes a second vibration motor, which is disposed on a side of the probe rod and is located 100-150 mm above the first purge ring.

[0008] In one embodiment, the purge module also includes a second purge ring, which is arranged on the side of the probe rod and is located 80-100 mm above the second vibration motor; the second purge ring is evenly provided with downward first auxiliary purge holes, and the purge direction of the first auxiliary purge holes is parallel to the probe rod.

[0009] In one embodiment, the diameter of the second purge ring is greater than or equal to the diameter of the first purge ring.

[0010] In one embodiment, the second purge ring is also evenly provided with second auxiliary purge holes that are inclined outward and downward.

[0011] In one embodiment, the first auxiliary purge hole is located outside the secondary purge hole.

[0012] A method for using a liquid level measurement anti-blocking device, the specific steps are as follows:

[0013] The first vibration motor, the first purge ring, the second vibration motor and the second purge ring are fixedly installed on the side of the probe rod from bottom to top, wherein the purge rod of the first purge ring faces the pressure-taking hole at the bottom of the probe rod, and the main purge hole of the purge rod faces the pressure-taking hole;

[0014] When the pressure-taking hole of the probe rod is blocked, start the first vibration motor and the second vibration motor to vibrate out the sludge in the pressure-taking hole, and then blow out high-pressure gas through the main purge hole of the first purge ring to blow out the sludge in the pressure-taking hole, and blow out high-pressure gas through the auxiliary purge hole of the first purge ring to disperse the sludge around the probe rod; the first auxiliary purge hole and the second auxiliary purge hole of the second purge ring both blow out high-pressure gas to disperse the sludge around the probe rod and the first purge ring.

[0015] In one embodiment, when the pressure-taking hole of the probe rod is blocked, the second purge ring and the second vibration motor are first started to blow away the sludge around the first purge ring and the probe rod, forming an environment with less sludge near the pressure-taking hole of the probe rod, and the second purge ring continuously blows out high-pressure gas;

[0016] Start the first vibration motor to shake out the sludge blocked in the pressure-taking hole of the probe rod, then start the first purge ring, aim the purge rod at the pressure-taking hole, blow out the shaken-out sludge, and blow out high-pressure gas through the auxiliary purge hole of the first purge ring to further disperse the sludge.

[0017] In one embodiment, when the second purge ring is started, the second vibration motor is first started to vibrate the entire probe rod to initially disperse the sludge around the probe rod, and the dispersed sludge is blown away in cooperation with the second purge ring;

[0018] Then turn off the second vibration motor, start the first vibration motor, shake out the sludge blocked in the pressure-taking hole of the probe rod, start the first purge ring, blow away the shaken-out sludge, then stop the first vibration motor and the second purge ring, and maintain the first purge ring to continuously blow out high-pressure gas.

[0019] In summary, the present invention has the following beneficial effects:

[0020] The present invention can be divided into two sets of vibration and purge devices, namely a first vibration motor and a first purge ring which are closer to the pressure taking hole, and a second vibration motor and a second purge ring which are farther away from the pressure taking hole. The first vibration motor and the first purge ring are directly aimed at the pressure taking hole to remove the sludge in the pressure taking hole, while the second vibration motor and the second purge ring are mainly aimed at the probe rod itself to separate the probe rod from the surrounding sludge, ensuring that after the sludge in the pressure taking hole is removed, a relatively clean environment is maintained near the pressure taking hole, thereby realizing automatic cleaning of the pressure taking hole of the static pressure level gauge, improving the accuracy of liquid level measurement, reducing the workload of manual maintenance of the static pressure level gauge, and being conducive to improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 It is a structural schematic diagram of the present invention.

[0022] In the figure: 1-probe rod, 2-pressure taking hole, 3-first vibration motor, 4-first purge ring, 5-second vibration motor, 6-second purge ring, 7-main purge hole, 8-secondary purge hole, 9-second auxiliary purge hole, 10-first auxiliary purge hole. DETAILED DESCRIPTION

[0023] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] It is worth noting that the directional words such as "upper" and "lower" involved in this article are all relative to the viewing angle of the drawings and are only for the convenience of description and cannot be understood as limitations on the technical solution.

[0025] The bottom of the straight-rod static pressure level gauge is a probe rod 1, which extends to the bottom of the pool, wherein there is a pressure hole 2 at the bottom of the probe rod 1, and the liquid in the pool enters the probe rod 1 through the pressure hole 2, and the liquid level is measured based on the principle that the measured liquid static pressure is proportional to the height of the liquid. However, the pool generally contains other impurities, and as the impurities precipitate at the bottom of the pool, the impurities will also flow into the pressure hole 2, eventually causing the pressure hole 2 to be blocked. If the static pressure level gauge is only taken out, the sludge in the pressure hole 2 is cleaned, and then the static pressure level gauge is placed in the pool, the pressure hole 2 will still be blocked soon, because the height of the sludge is higher than the height of the pressure hole 2, and the sludge flows into the pressure hole 2 together with the water to cause blockage. Therefore, the existing treatment method is generally to remove all the sludge at the bottom of the pool when stopping production, but the sludge cannot be removed during production, and the sludge in the pressure hole 2 of the static pressure level gauge can only be frequently cleaned.

[0026] In response to the above problems, Figure 1 As shown, the present invention provides a liquid level measurement anti-clogging device, including a vibration module and a purge module, the vibration module including a first vibration motor 3, the first vibration motor 3 is arranged on the side of the probe rod 1 of the static pressure level gauge, and the first vibration motor 3 is 50-70mm away from the bottom of the probe rod 1, the purge module includes a first purge ring 4, the first purge ring 4 is arranged on the side of the probe rod 1, and is located 100-150mm above the first vibration motor 3; the first purge ring 4 is evenly provided with a plurality of purge rods inclined toward the pressure taking hole 2 at the bottom of the probe rod 1, and the purge rod is provided with a main purge hole 7 facing the pressure taking hole 2.

[0027] Specifically, the first vibration motor 3 is arranged on the side of the probe rod 1. Under natural conditions, the silt deposited at the bottom of the pool will cover the bottom of the probe rod 1, and the silt will contact the probe rod 1. The function of the vibration motor of the present invention is to make the probe rod 1 vibrate itself, shake off the silt around the probe rod 1, and loosen the silt blocking the pressure hole 2 at the same time.

[0028] The vibration motor of the present invention needs to be used in conjunction with a purge ring. The first vibration motor 3 initially shakes out the sludge in the pressure taking hole 2, and the sludge still remains in the pressure taking hole 2. The purge rod of the first purge ring 4 is directed toward the pressure taking hole 2, and high-pressure gas is blown into the pressure taking hole 2 to blow out the loosened sludge, thereby automatically cleaning the sludge clogged in the pressure taking hole 2.

[0029] In the present invention, the first purge ring 4 is also evenly provided with auxiliary purge holes 8 for downward purge, and the purge direction of the auxiliary purge holes 8 is parallel to the probe rod 1 .

[0030] Specifically, the first purge ring 4 includes two types of purge holes. The function of the main purge hole 7 is to blow out the sludge in the pressure taking hole 2. Therefore, the purge rod needs to be inclined toward the pressure taking hole, and the number of purge rods is greater than or equal to the number of pressure taking holes 2; the purge direction of the auxiliary purge hole 8 is parallel to the rod body of the probe rod 1, and is used in conjunction with the vibration motor. After the sludge in the pressure taking hole 2 is blown out, high-pressure gas is blown out from the auxiliary purge hole 8 to further blow away the sludge around the pressure taking hole 2, ensuring that there is no sludge near the pressure taking hole 2.

[0031] It should be noted that the structure of the first purge ring 4 is an annular purge tube, which is connected to an external gas source through a gas pipeline, wherein the purge rod can be directly connected to the first purge ring 4, that is, the external gas source provides high-pressure gas to the main purge hole 7 and the auxiliary purge hole 8 at the same time, and the gas pressure blown out from the main purge hole 7 and the auxiliary purge hole 8 is the same.

[0032] Furthermore, the vibration module further comprises a second vibration motor 5 , which is arranged on the side of the probe rod 1 and is located 100-150 mm above the first purge ring 4 .

[0033] Specifically, the first vibration motor 3 and the second vibration motor 5 are arranged on the side of the probe rod 1 from bottom to top. The function of the first vibration motor 3 is not exactly the same as that of the second vibration motor 5. Specifically, the first vibration motor 3 is closer to the pressure taking hole 2 at the bottom of the probe rod 1, which is beneficial to shake and loosen the silt blocked in the pressure taking hole 2, while the second vibration motor 5 is farther from the bottom of the probe rod 1, and has less effect on vibrating the silt blocked in the pressure taking hole 2, but has a greater effect on vibrating the probe rod 1 as a whole, thereby separating the probe rod 1 from the surrounding silt.

[0034] Furthermore, the purge module also includes a second purge ring 6, which is arranged on the side of the probe rod 1 and is located 80-100 mm above the second vibration motor 5; the second purge ring 6 is evenly provided with downward first auxiliary purge holes 10, the purge direction of the first auxiliary purge holes 10 is parallel to the probe rod 1, and the first auxiliary purge holes 10 are located on the outside of the secondary purge hole 8, and the second purge ring 6 is also evenly provided with second auxiliary purge holes 9 obliquely outward and downward.

[0035] Specifically, the present invention can be divided into two sets of vibration and purge devices, namely a first vibration motor 3 and a first purge ring 4 which are closer to the pressure taking hole 2, and a second vibration motor 5 and a second purge ring 6 which are farther away from the pressure taking hole 2. The first vibration motor 3 and the first purge ring 4 are directly aimed at the pressure taking hole 2 to remove the sludge in the pressure taking hole 2, while the second vibration motor 5 and the second purge ring 6 are mainly aimed at the probe rod 1 itself to separate the probe rod 1 from the surrounding sludge, thereby ensuring that after the sludge in the pressure taking hole 2 is removed, a relatively clean environment is maintained near the pressure taking hole 2.

[0036] Among them, the second purge ring 6 is also an annular purge tube, which is connected to an external gas source through a gas pipeline. It should be noted that the gas source of the second purge ring 6 and the gas source of the first purge ring 4 are two independent gas sources. The gas pressure blown out by the second purge ring 6 needs to be greater than the gas pressure of the first purge ring 4. This is because the second purge ring 6 is the farthest from the bottom of the probe rod 1, and the gas blown out by the second purge ring 6 needs a greater pressure to reach the bottom of the probe rod 1.

[0037] In the present invention, the second purge ring 6 includes two types of purge holes, namely a first auxiliary purge hole 10 whose purge direction is parallel to the probe rod 1 and a second auxiliary purge hole 9 obliquely outward and downward, both of which cooperate with the second vibration motor 5 to separate the rod body of the probe rod 1 from the surrounding sludge.

[0038] It should be noted that the diameter of the second purge ring 6 is greater than or equal to the diameter of the first purge ring 4. Preferably, the diameter of the second purge ring 6 is greater than the diameter of the first purge ring 4. Since the second purge ring 6 is located above the first purge ring 4, and both blow high-pressure gas to the bottom of the probe rod 1, in order to prevent the second purge ring 6 from affecting the first purge ring 4 from blowing out the sludge in the pressure-taking hole 2, the diameter of the second purge ring 6 is greater than or at least equal to the diameter of the first purge ring 4.

[0039] It should be noted that the vibration motor and the purge ring of the present invention are both detachably connected to the probe rod 1 .

[0040] The present invention also provides a method for using a liquid level measurement anti-clogging device, the specific steps of which are as follows:

[0041] The first vibration motor 3, the first purge ring 4, the second vibration motor 5 and the second purge ring 6 are fixedly installed on the side of the probe rod 1 from bottom to top, wherein the purge rod of the first purge ring 4 faces the pressure-taking hole 2 at the bottom of the probe rod 1, and the main purge hole 7 of the purge rod faces the pressure-taking hole;

[0042] When the pressure-taking hole 2 of the probe rod 1 is blocked, start the first vibration motor 3 and the second vibration motor 5 to vibrate out the sludge in the pressure-taking hole 2, and then blow out high-pressure gas through the main purge hole 7 of the first purge ring 4 to blow out the sludge in the pressure-taking hole 2, and blow out high-pressure gas through the auxiliary purge hole 8 of the first purge ring 4 to disperse the sludge around the probe rod 1; the first auxiliary purge hole 10 and the second auxiliary purge hole 9 of the second purge ring 6 both blow out high-pressure gas to disperse the sludge around the probe rod 1 and the first purge ring 4.

[0043] It should be noted that the purge ring and the vibration motor are not activated at the same time, the first purge ring 4 and the second purge ring 6 may not be activated at the same time, and the first vibration motor 3 and the second vibration motor 5 may not be activated at the same time. The vibration motor can be started first to form a relatively clean environment on the side of the rod body of the probe rod 1, and then the purge ring can be activated to blow away the surrounding sludge and blow out the sludge in the pressure taking hole 2; the purge ring can also be started first, especially the second purge ring 6, to blow away the sludge around the rod body, and then the vibration motor can be started to shake out the sludge in the pressure taking hole 2.

[0044] Specifically, when the pressure-taking hole 2 of the probe rod 1 is blocked, the second purge ring 6 and the second vibration motor 5 are first started to blow away the sludge around the first purge ring 4 and the probe rod 1, forming an environment with less sludge near the pressure-taking hole 2 of the probe rod 1, and the second purge ring 6 continuously blows out high-pressure gas;

[0045] Start the first vibration motor 3 to shake out the sludge blocked in the pressure hole 2 of the probe rod 1, then start the first purge ring 4, aim the purge rod at the pressure hole 2, blow out the shaken sludge, and blow out high-pressure gas through the auxiliary purge hole 8 of the first purge ring 4 to further disperse the sludge.

[0046] It should be noted that the second vibration motor 5 vibrates continuously for 10-60 seconds, and the first auxiliary purge hole 10 and the second auxiliary purge hole 9 of the second purge ring 6 continuously blow high-pressure gas to the bottom of the probe rod 1. The second vibration motor 5 cooperates with the second purge ring 6 to blow away the silt around the rod body of the probe rod 1, and form a relatively clean space around the probe rod 1 that is larger than the diameter of the second purge ring 6, to prevent the surrounding silt from entering the pressure taking hole 2 again and causing blockage when the silt in the pressure taking hole 2 is cleaned; the first vibration motor 3 vibrates continuously for 60-120 seconds to loosen the silt blocked in the pressure taking hole 2 and initially shake it out, and then blows out high-pressure gas through the main purge hole 7 of the first purge ring 4 to blow out the silt.

[0047] It should be noted that the purge rod needs to be used in conjunction with the first vibration motor 3. Because the purge rod is facing the pressure taking hole 2, if the first vibration motor 3 is not started, the purge rod cannot blow out the sludge in the pressure taking hole 2. It is necessary to wait for the first vibration motor 3 to start for a period of time before starting the purge rod to blow high-pressure gas directly toward the pressure taking hole 2. The high-pressure gas impacts the fluffy sludge and blows the sludge away or out, so that the pressure taking hole 2 is no longer blocked.

[0048] It should be noted that the second purge ring 6 can continue to blow out high-pressure gas after being started to maintain a clean environment around the rod body of the probe rod 1, and can also be closed after a period of time to save energy.

[0049] For example, when the second purge ring 6 is started, the second vibration motor 5 is started first to vibrate the entire probe rod 1, initially shaking off the sludge around the probe rod 1, and then the second purge ring 6 is used to blow off the shaken sludge;

[0050] Then, the second vibration motor 5 is turned off, and the first vibration motor 3 is started to shake out the sludge blocked in the pressure-taking hole 2 of the probe rod 1, and the first purge ring 4 is started to blow away the shaken-out sludge, and then the first vibration motor 3 and the second purge ring 6 are stopped, and the first purge ring 4 is maintained to continuously blow out high-pressure gas.

[0051] It should be noted that the first purge ring 4 can also be closed after a period of time, such as 60-120 seconds, to save energy. When the pressure-taking hole 2 is blocked again, the vibration motor and the purge ring are started again.

[0052] The present invention uses specific embodiments to illustrate the use method of the present invention.

[0053] The first vibration motor 3, the first purge ring 4, the second vibration motor 5 and the second purge ring 6 are fixedly installed on the side of the probe rod 1 from bottom to top. Specifically, the first vibration motor 3 is 50 mm away from the bottom of the probe rod 1, the first purge ring 4 is 100 mm away from the first vibration motor 3, the second vibration motor 5 is 100 mm away from the first purge ring 4, and the second purge ring 6 is 100 mm away from the second vibration motor 5, wherein the purge rod of the first purge ring 4 faces the pressure-taking hole 2 at the bottom of the probe rod 1, and the main purge hole 7 of the purge rod faces the pressure-taking hole 2;

[0054] When the liquid level of the pool is in doubt, the second vibration motor 5 is started first. After the second vibration motor 5 continues to vibrate for 30 seconds, the second purge ring 6 is activated to blow away the sludge around the rod body. After the second purge ring 6 is activated for 10 seconds, the second vibration motor 5 is stopped to maintain the second purge ring 6 to continuously blow out high-pressure gas.

[0055] Then start the first vibration motor 3. After the first vibration motor 3 continues to vibrate for 50 seconds, activate the first purge ring 4 to blow out the fluffy sludge in the pressure hole 2. The liquid level of the pool measured by the static pressure level gauge is consistent with the actual height. After the first purge ring 4 is activated for 20 seconds, stop the first vibration motor 3 and the second purge ring 6. After the first purge ring 4 is activated for 120 seconds, stop the first purge ring 4.

[0056] Repeat the above operation every half an hour to achieve automatic cleaning of the pressure taking hole 2.

[0057] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
