Description

Technical Field

[0001] The present invention relates to the technical field of static pressure liquid level gauges, and more particularly to a floating pressure guiding device of a static pressure liquid level gauge and a use method thereof. Background Art

[0002] In steel enterprises, turbid ring hot water pools are generally used to collect hot wastewater in production. Turbid ring hot water pools contain more impurities, and the liquid level height is also a place that needs attention in normal production. Turbid ring hot water pools are unmanned and are automatically pumped and replenished. The automatic pumping and replenishment depends on the data of the liquid level meter to judge. When the liquid level meter detection data is wrong, it will directly affect the liquid level height of the turbid ring hot water pool. Ultrasonic level meters, radar level meters or static pressure level meters are generally used to detect the liquid level height of the turbid ring hot water pool. However, there will be the following problems: the steam mist generated by the turbid ring hot water pool will adhere to the ultrasonic level meter or radar level meter. The probe of the level gauge affects the normal echo of the level gauge, causing distortion of the detected liquid level. This can easily lead to the pool liquid level being too low, directly affecting production, or the liquid level being too high, causing overflow waste, and direct overflow discharge will cause environmental problems. Using a static pressure level gauge can solve the above problems, but it brings another problem. Since the turbid ring hot water pool contains more impurities, the bottom probe of the static pressure level gauge is very easy to be blocked. The static pressure level gauge is based on the pressure difference formed by the pool liquid level height on the pool bottom liquid gauge probe, and the pressure difference value is converted into a linear current signal to reflect the liquid level height. When the bottom probe is blocked, it will directly affect the detection results. Therefore, it is necessary to propose a new device to solve the above problems. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a floating pressure-guiding device for a hydrostatic level gauge and a method of use, in which a floating portion drives a hose connected to a probe of the hydrostatic level gauge at the bottom of the pool, thereby effectively preventing the probe of the hydrostatic level gauge from being blocked.

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

[0005] A floating pressure-guiding device for a static pressure level gauge includes a static pressure level gauge and a pressure-guiding device connected to the static pressure level gauge. The pressure-guiding device includes a floating portion and a hose. The floating portion is maintained above the liquid surface. The bottom end of the hose is connected to the bottom end of the static pressure level gauge, and the top end of the hose is connected to the floating portion. A water inlet is also provided at the top end of the side of the hose for making the liquid level in the hose the same as the pool water level.

[0006] The principle behind this invention is that the hose isolates the sensor at the bottom of the hydrostatic level gauge from the pool bottom, preventing debris from clogging the gauge. Furthermore, because the liquid level within the hose is the same as the pool water level, the hydrostatic level gauge can also detect the pool water level by detecting the water pressure within the hose. Specifically, because the hose's water inlet is located at the top, away from the pool bottom, impurities in a turbid hot water pool will settle to the bottom under gravity. Therefore, the hose's water inlet is located away from impurities, significantly reducing the risk of clogging the hydrostatic level gauge.

[0007] In one embodiment, an auxiliary tube is installed on the side of the hose, connected to the hose's water inlet, with the opening of the auxiliary tube facing downward. This additional auxiliary tube, with its opening facing downward, helps ensure that the hose is always filled with pool water. It's easy to understand that if only the water inlet is located at the top of the hose's side, impurities in the pool could still enter the hose. However, by installing a downward-facing auxiliary tube at the water inlet, even if impurities enter the auxiliary tube, they will sink out of the tube under the action of their own gravity.

[0008] In one embodiment, a filter is provided at the bottom end of the auxiliary pipe. The filter serves to restrict the entry of impurities into the auxiliary pipe. Because the hose and auxiliary pipe are immersed in pool water for extended periods, floating impurities may still enter the hose through the auxiliary pipe and accumulate at the sensor probe. The filter provided on the auxiliary pipe effectively prevents impurities from entering the auxiliary pipe.

[0009] In one embodiment, the floating pressure-guiding device of the static pressure level gauge further includes an air blowing device, comprising an air supply device and an air blowing pipe. The top end of the air blowing pipe is connected to the air supply device, the bottom end of the air blowing pipe is connected to the auxiliary pipe, and the bottom end of the air blowing pipe is directed toward the filter. Specifically, when the filter is completely covered with impurities, the air supply device is activated, and the air blowing pipe blows high-pressure air toward the filter, thereby clearing the impurities from the filter.

[0010] In one embodiment, a detection sensor is provided at the top end of the hose. The detection sensor is in contact with the liquid surface in the hose to detect whether the liquid level in the hose is normal.

[0011] In one embodiment, an installation chamber is provided at the bottom end of the hose, and a probe of the static pressure level gauge is provided in the installation chamber.

[0012] In one embodiment, the floating portion is a float.

[0013] A method for using a floating pressure guiding device of a static pressure level gauge is provided, and the specific steps are as follows:

[0014] Place the probe of the static pressure level gauge in the installation chamber at the bottom of the hose, and place the installation chamber and the hose in the turbid ring hot water pool. The installation chamber drives the probe to sink to the bottom of the turbid ring hot water pool. At the same time, the hose is entirely in the pool water. The top of the hose is driven by the floating part to float on the liquid surface of the turbid ring hot water pool. The pool water flows into the hose through the auxiliary pipe and fills the hose. At this time, the liquid surface in the hose is flush with the liquid surface of the turbid ring hot water pool. The static pressure level gauge obtains the liquid level of the turbid ring hot water pool by measuring the liquid level in the hose.

[0015] In one embodiment, the air supply device is activated regularly or irregularly, and high-pressure air is blown out through the air blowing pipe toward the filter screen of the auxiliary pipe, thereby blowing out impurities deposited on the filter screen.

[0016] In one embodiment, when the detection sensor fails to detect the liquid level in the hose, the air supply device is automatically activated for 30-60 seconds, and compressed air is blown out of the filter screen of the auxiliary pipe through the air blowing pipe to blow out the impurities deposited on the filter screen;

[0017] If the detection sensor detects liquid in the hose again, the air supply device is stopped;

[0018] If the detection sensor still cannot detect the liquid in the hose after 60 seconds of starting the air supply device, an alarm will be issued.

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

[0020] The present invention separates the probe from the pool bottom environment through a hose. The hose serves to isolate the sensor at the bottom of the static pressure level gauge from the pool bottom, preventing debris from clogging the static pressure level gauge. At the same time, since the liquid level in the hose is the same as the pool water level, the static pressure level gauge can also know the pool water level by detecting the water pressure in the hose, effectively solving the problem of probe clogging of the static pressure level gauge.

[0023] The present invention is described in detail below with reference to 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 perspective of the drawings. They are only for the convenience of description and cannot be understood as limitations on the technical solution.

[0025] The probe 3 of the existing static pressure level gauge 2 at the bottom of the pool is often blocked, which makes it very difficult to automatically control the liquid level of the turbid ring hot water pool 1 by the static pressure level gauge 2. In fact, the degree of automation is not high and manual maintenance is often required. The present invention focuses on the reason why the probe 3 of the static pressure level gauge 2 is blocked. It is because there are many impurities in the turbid ring hot water pool 1. Moreover, under the action of gravity, the impurities will settle at the bottom of the pool and cover the probe 3. However, there are relatively few impurities near the liquid level of the turbid ring hot water pool 1. Therefore, the present invention provides a floating pressure guide device for a static pressure level gauge, such as Figure 1 As shown, it includes a hydrostatic liquid level gauge 2 and a pressure-guiding device connected to the hydrostatic liquid level gauge 2. The pressure-guiding device includes a floating portion 5 and a hose 4. The floating portion 5 is maintained above the liquid surface. The bottom end of the hose 4 is connected to the bottom end of the hydrostatic liquid level gauge 2. The top end of the hose 4 is connected to the floating portion 5. A water inlet is also provided at the top end of the side of the hose 4 to make the liquid level in the hose 4 the same as the pool water level.

[0026] The basic principle of the present invention is to separate the probe 3 from the pool bottom environment via a hose 4. The hose 4 serves to isolate the sensor at the bottom of the hydrostatic level gauge 2 from the pool bottom, preventing debris from clogging the hydrostatic level gauge 2. Furthermore, because the liquid level within the hose 4 is the same as the pool water level, the hydrostatic level gauge 2 can also detect the pool water level by detecting the water pressure within the hose 4. Specifically, because the water inlet of the hose 4 is located at the top, away from the pool bottom, impurities in the turbid hot water pool 1 will settle to the pool bottom under the action of gravity. Therefore, the water inlet end of the hose 4 of the present invention is far away from impurities, greatly reducing the risk of clogging the hydrostatic level gauge 2.

[0027] In addition, since the water inlet of the hose 4 is small, the possibility of impurities in the turbid ring hot water pool 1 entering the hose 4 is also small, which effectively prevents impurities from being deposited on the probe 3 and causing blockage.

[0028] Furthermore, as attached Figure 1 As shown, an auxiliary tube 6 is installed on the side of the hose 4, connected to the water inlet of the hose 4, with the opening of the auxiliary tube 6 facing downward. The present invention provides an additional auxiliary tube 6 on the hose 4, with its opening facing downward, which helps ensure that the hose 4 is always filled with pool water. It is easy to understand that if the water inlet is only provided at the top of the side of the hose 4, impurities in the pool may still enter the hose 4. However, the present invention provides an auxiliary tube 6 with a downward-facing opening at the water inlet. Even if impurities enter the auxiliary tube 6, they will sink out of the auxiliary tube 6 under the action of their own gravity.

[0029] It should be noted that the length of the auxiliary tube 6 should not be too long, and 10-15 cm is sufficient. It is easy to understand that if the auxiliary tube 6 is too long, the bottom of the auxiliary tube 6 will still be close to the area at the bottom of the pool where there are more impurities. When the pool water flows into the auxiliary tube 6 and the hose 4, it is easy to suck in the impurities together.

[0030] Furthermore, a filter screen 7 is provided at the bottom end of the auxiliary tube 6. The filter screen 7 is designed to restrict the entry of impurities into the auxiliary tube 6. Because the hose 4 and the auxiliary tube 6 are immersed in pool water for extended periods, floating impurities may still enter the hose 4 through the auxiliary tube 6 and accumulate near the sensor probe 3. The filter screen 7 provided on the auxiliary tube 6 of the present invention effectively prevents impurities from entering the auxiliary tube 6.

[0031] Furthermore, the floating pressure-guiding device of the static pressure level gauge also includes an air blowing device, which includes an air supply device 9 and an air blowing pipe 10. The top end of the air blowing pipe 10 is connected to the air supply device 9, and the bottom end of the air blowing pipe 10 is connected to the auxiliary pipe 6. The bottom end of the air blowing pipe 10 is directed toward the filter 7. Specifically, when the filter 7 is completely covered with impurities, the air supply device 9 is activated, and the air blowing pipe 10 blows high-pressure air toward the filter 7, thereby clearing the impurities from the filter 7.

[0032] It is easy to understand that since the impurities are attached to the outer surface of the filter 7, when the air pipe 10 on the inner surface side of the filter 7 blows out high-pressure air, all the impurities attached to the outer surface of the filter 7 can be blown away, thereby preventing the impurities from obstructing the flow of pool water into the auxiliary pipe 6 and the hose 4.

[0033] Furthermore, a detection sensor 8 is provided at the top end of the hose 4 . The detection sensor 8 is in a state of just contacting the liquid surface in the hose 4 to detect whether the liquid level in the hose 4 is in a normal state.

[0034] The detection sensor 8 described in the present invention is a conventional sensor used to detect the presence of liquid. The sensor 8 is positioned at the top of the hose 4 to detect whether the liquid level within the hose 4 is flush with the liquid level within the turbid ring hot water tank 1 when the float 5 is functioning properly. It will be readily understood that the position of the detection sensor 8 is based on the slightly lower liquid level within the hose 4 when the float 5 propels the hose 4 within the turbid ring hot water tank 1. In other words, the detection sensor 8 needs to be in contact with the liquid surface. If the detection sensor 8 fails to detect the liquid level, it indicates that the liquid level within the hose 4 is lower than that within the turbid ring hot water tank 1.

[0035] In the present invention, an installation chamber 11 is provided at the bottom end of the hose 4 , and the probe 3 of the static pressure level gauge 2 is provided in the installation chamber 11 ; the floating portion 5 is a float.

[0036] A method for using a floating pressure guiding device of a static pressure level gauge is provided, and the specific steps are as follows:

[0037] Place the probe 3 of the static pressure level gauge 2 in the installation chamber 11 at the bottom end of the hose 4, and place the installation chamber 11 and the hose 4 in the turbid ring hot water pool 1. The installation chamber 11 drives the probe 3 to sink to the bottom of the turbid ring hot water pool 1. At the same time, the hose 4 is entirely in the pool water. The top of the hose 4 is driven by the floating part 5 to float on the liquid surface of the turbid ring hot water pool 1. The pool water flows into the hose 4 through the auxiliary pipe 6 and fills the hose 4. At this time, the liquid surface in the hose 4 is flush with the liquid surface of the turbid ring hot water pool 1. The static pressure level gauge 2 obtains the liquid level height of the turbid ring hot water pool 1 by measuring the liquid level height in the hose 4.

[0038] Furthermore, the air supply device 9 is started regularly or irregularly, and high-pressure air is blown out to the filter screen 7 of the auxiliary pipe 6 through the air blowing pipe 10, thereby blowing out the impurities deposited on the filter screen 7.

[0039] Furthermore, when the detection sensor 8 fails to detect the liquid level in the hose 4, the air supply device 930-60s is automatically activated, and compressed air is blown out through the air blowing pipe 10 toward the filter 7 of the auxiliary pipe 6, blowing out the impurities deposited on the filter 7;

[0040] If the detection sensor 8 detects the liquid in the hose 4 again, the air supply device 9 is stopped;

[0041] If the detection sensor 8 still cannot detect the liquid in the hose 4 after starting the air supply device 960s, an alarm will be issued.

[0042] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
