Technical Field
[0001] This utility model belongs to the field of separation equipment technology, specifically relating to a liquid volume detection and discharge mechanism for a compressor unit separation tank. Background Technology
[0002] During the operation of the gas-liquid separator, gas and liquid need to be separated in the separation tank. The separated gas is discharged through the exhaust port, while the separated liquid is accumulated in the separation tank and discharged through the drain pipe. Therefore, in order to prevent the separation operation from being affected by excessive liquid accumulation in the separation tank, it is necessary to measure the liquid level in the separation tank through a liquid level measuring mechanism (such as a magnetic float liquid level gauge) to prevent the problem of excessive liquid in the separation tank.
[0003] In existing technologies, taking magnetic level gauges as an example, most of the time, workers still rely on visual observation of the level gauge's flip plate value during use. This method is not very accurate, and during long-term separation operations, it cannot be guaranteed that workers will not miss or become fatigued, which may lead to workers not being able to drain the liquid in the separation tank in time, resulting in excessive liquid accumulation in the tank and affecting the separation work. Utility Model Content
[0004] In view of this, the present invention provides a liquid level detection and discharge mechanism for a compressor unit separator tank. Its purpose is to enable the drain pipe to automatically discharge the liquid in the separator tank after the liquid reaches a specified height, without requiring the staff to constantly monitor the liquid level gauge, thus reducing the workload of the staff.
[0005] The technical solution adopted in this utility model is as follows:
[0006] A liquid level detection and discharge mechanism for a compressor unit separator tank includes a tank body and a drain pipe. A liquid storage cavity is formed inside the tank body. The drain pipe passes through the bottom of the tank body and communicates with the liquid storage cavity, discharging liquid from the cavity through the drain pipe. A drain valve is provided on the drain pipe. The mechanism also includes a measuring mechanism installed along the vertical height of the liquid storage cavity. The measuring mechanism includes:
[0007] The main pipeline is vertically installed on one side of the tank body, and a floating cavity is provided inside the main pipeline, which extends along the length of the main pipeline;
[0008] The liquid guiding section is connected between the main pipeline and the tank body, and its two ends are respectively connected to the liquid storage cavity and the floating cavity. The liquid guiding section guides the liquid in the liquid storage cavity into the floating cavity.
[0009] A magnetic float is movably disposed within the floating cavity. When liquid is injected into the floating cavity, the magnetic float floats within the floating cavity.
[0010] The length of the floating cavity is equal to the height of the liquid storage cavity, and a magnetic switch is provided at the top of the main pipeline. The magnetic switch is electrically connected to the drain valve through a control unit.
[0011] As a preferred technical solution, the liquid guiding part includes a low-level conduit and a high-level conduit, wherein the low-level conduit is connected between the bottom of the floating cavity and the bottom of the liquid storage cavity, and the high-level conduit is connected between the top of the floating cavity and the top of the liquid storage cavity.
[0012] Furthermore, both the high-level conduit and the low-level conduit are fitted with flanges, which fix the high-level conduit and the low-level conduit to the tank body.
[0013] Furthermore, both the high-position conduit and the low-position conduit are provided with a filter section at one end connected to the floating cavity, and the filter section includes two filter screens arranged opposite each other.
[0014] Furthermore, the surface of the filter screen is recessed towards the floating cavity.
[0015] Furthermore, it also includes:
[0016] A label plate is installed on the side of the main pipeline away from the tank body and extends along the length of the main pipeline. The label plate is provided with scale lines distributed along the length of the floating cavity.
[0017] A magnetic flip panel is movably installed inside the signboard, and several magnetic flip panels are arranged in an array along the length of the signboard.
[0018] Furthermore, the bottom of the main pipeline is provided with an installation flange, and the interior of the installation flange is provided with a drain pipe, wherein the drain pipe is connected to the floating cavity, and the liquid in the floating cavity is discharged by the drain pipe.
[0019] Furthermore, the main pipe is a transparent pipe.
[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0021] By using a magnetic float and a magnetic control switch, when the liquid level reaches a preset height, the magnetic float and the magnetic control switch contact each other, prompting the control unit to send an electrical signal to open the drain valve and initiate the automatic discharge process. As liquid continues to be discharged from the storage cavity, the liquid level gradually decreases, and the magnetic float descends synchronously. When the liquid level drops to a specific level, the magnetic float disengages from the magnetic control switch, the control unit receives a stop signal, and the drain valve immediately closes, thus terminating the liquid discharge operation. The entire operation requires no manual intervention, achieving automatic detection and discharge of liquid within the separator tank, ensuring the safe and stable operation of the separator tank.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] In existing technologies, taking magnetic level gauges as an example, their operation typically relies on operators visually observing the level readings. However, this method is not very accurate. During prolonged separation operations, it's impossible to guarantee that operators won't miss readings or become fatigued. This could lead to insufficient liquid drainage from the separation tank, resulting in excessive liquid accumulation and hindering the smooth progress of the separation process.
[0029] Example 1: Therefore, in order to solve the above problems and realize the function of automatically discharging the liquid in the separator, this utility model discloses a liquid volume detection and discharge mechanism for the separator of a compressor unit, see reference. Figures 1-3 The system includes a tank body 1 and a drain pipe 3. The tank body 1 has a liquid storage cavity on its inner side. The drain pipe 3 passes through the bottom of the tank body 1 and is connected to the liquid storage cavity. The liquid in the liquid storage cavity is discharged by the drain pipe 3. Specifically, the drain pipe 3 is equipped with a drain valve. The system also includes a measuring mechanism 2 installed along the vertical height of the liquid storage cavity. The measuring mechanism 2 includes a main pipe 4, a liquid guiding part 5, and a magnetic float 12.
[0030] The main pipe 4 is vertically arranged on one side of the tank body 1. A floating cavity 11 is opened inside the main pipe 4, and the floating cavity 11 extends along the length of the main pipe 4. The liquid guiding part 5 is connected between the main pipe 4 and the tank body 1, and the two ends of the liquid guiding part 5 are respectively connected to the liquid storage cavity and the floating cavity 11. The liquid guiding part 5 guides the liquid in the liquid storage cavity into the floating cavity. The magnetic float 12 is movably arranged in the floating cavity 11. When liquid is injected into the floating cavity 11, the magnetic float 12 floats in the floating cavity 11.
[0031] In this embodiment, the liquid guiding part 5 can guide the liquid in the storage cavity into the floating cavity 11. As the liquid level in the storage cavity rises, more liquid is guided into the floating cavity 11. At this time, the magnetic float 12 will move upward along the floating cavity 11 of the main pipe 4 as the liquid level in the storage cavity rises. The current liquid level in the storage cavity can be determined based on the upward height of the magnetic float 12, so as to achieve the purpose of measuring the liquid level in the tank 1.
[0032] To facilitate staff observation of the position of the magnetic levitation element 12, the main pipe 4 is a transparent pipe.
[0033] Furthermore, the length of the floating cavity 11 is equal to the height of the liquid storage cavity, and a magnetic control switch is provided at the top of the main pipe 4. The magnetic control switch is electrically connected to the drain valve through the control unit.
[0034] When the liquid storage cavity is filled with liquid, the liquid level rises to the top of the cavity. At this point, the magnetic float 12 also rises to the top of the floating cavity 11, allowing the magnetic switch to contact it. When the magnetic switch contacts the float 12, it sends an electrical signal to the control unit, which then opens the drain valve, allowing the drain pipe 3 to discharge the liquid from the storage cavity, thus achieving automatic discharge. This design ensures that excess liquid is promptly discharged when the liquid level in the storage cavity reaches a preset height, preventing overflow.
[0035] When the liquid level in the storage cavity decreases, the magnetic float 12 in the floating cavity 11 will descend along with the liquid level. Since the contact between the magnetic float 12 and the magnetic control switch is based on the liquid level, when the liquid level drops to a certain level, the magnetic float 12 will disengage from the magnetic control switch. At this time, the control unit no longer receives the signal to open the drain valve, the drain valve closes, and liquid discharge stops.
[0036] It should be noted that the magnetic switch can be a reed switch, the drain valve can be a solenoid valve, and the control unit can be a component with transmission function, such as a microcontroller. The above components are existing technologies and will not be described in detail below.
[0037] Example 2: Based on Example 1, in order to improve the accuracy of liquid level measurement, refer to... Figure 2 and Figure 3 The liquid guiding part 5 includes a low-level conduit and a high-level conduit, wherein the low-level conduit is connected between the bottom of the floating cavity 11 and the bottom of the liquid storage cavity, and the high-level conduit is connected between the top of the floating cavity 11 and the top of the liquid storage cavity.
[0038] In this embodiment, by setting up low-level and high-level conduits, liquid can be simultaneously guided from the top and bottom of the liquid storage cavity to the floating cavity 11. This helps the magnetic float 12 to float more smoothly as the liquid level rises, avoiding the impact of liquid flow or uneven buoyancy caused by liquid inflow from one side, which affects the normal floating of the magnetic float 12, thereby improving the accuracy of liquid level measurement.
[0039] Meanwhile, in order to improve the connection stability between the liquid guiding part 5 and the tank body 1, flanges 6 are fitted on both the high-level conduit and the low-level conduit. The flanges 6 fix the high-level conduit and the low-level conduit to the tank body 1. In a specific embodiment, the flanges 6 and the tank body 1 can be fastened with bolts or other connecting parts. This fixing method is firm and reliable, which can effectively prevent the conduit from being displaced or loosened due to liquid flow impact, vibration and other factors during equipment operation, ensuring the stability and continuity of the liquid guiding process, and thus ensuring the normal operation of the entire liquid volume detection and discharge mechanism.
[0040] Example 3: Based on Example 2, the liquid in the tank 1 contains metallic impurities. If these metallic impurities come into contact with the magnetic float 12, they will be adsorbed onto the magnetic float 12, which will have an adverse effect on the magnetism and buoyancy of the magnetic float 12. Therefore, in order to prevent impurities in the liquid in the tank 1 from entering the floating cavity 11, the high-level conduit and the low-level conduit are both provided with a filter section at one end connected to the floating cavity 11, and the filter section includes two filter screens arranged opposite to each other.
[0041] In this embodiment, when the liquid in the storage cavity flows to the floating cavity 11 through the conduit, impurities in the liquid are intercepted by the filter screen, preventing impurities from entering the floating cavity 11 and depositing at the bottom or adsorbing on the surface of the magnetic float 12, thus affecting the buoyancy and smooth movement of the magnetic float 12. This is intended to maintain the accuracy of the magnetic float 12 in reflecting the liquid level height, while also reducing the damage of impurities to the internal structure of the entire measuring mechanism 2 and extending the service life of the equipment.
[0042] In one embodiment, to enhance the filtration effect, the surface of the filter screen is recessed towards the floating cavity 11. This recessed design helps increase the contact area between the filter screen and the liquid, allowing the liquid to come into greater contact with the filter screen surface as it passes through, thereby improving the interception efficiency of impurities. Simultaneously, the recessed structure can also increase the liquid flow rate to some extent, enabling the liquid to enter the floating cavity 11 more quickly, which helps improve the response speed to changes in the liquid level within the storage cavity.
[0043] Example 4: Based on Example 1, to facilitate workers' intuitive observation of the liquid level, an indicator plate 7 and a magnetic flip plate 8 are also included. The indicator plate 7 is installed on the side of the main pipe 4 away from the tank 1, and the indicator plate 7 extends along the length direction of the main pipe 4. The indicator plate 7 has scale lines distributed along the length direction of the floating cavity 11. The magnetic flip plate 8 is movably installed inside the indicator plate 7, and several magnetic flip plates 8 are arrayed along the length direction of the indicator plate 7.
[0044] In this embodiment, when the magnetic float 12 moves up and down with the liquid level in the floating cavity 11, the magnetic field of the magnetic float 12 will cause the magnetic flip plate 8 at the corresponding position to flip due to the principle of buoyancy and based on the magnetic coupling effect. By observing the correspondence between the flipped position of the magnetic flip plate 8 and the scale line on the marking plate 7, the staff can intuitively read the liquid level height, which is convenient for the staff to monitor the liquid level in the tank 1 in real time.
[0045] In a specific implementation, the staff can paint different colors, such as red and white, on the two sides of the magnetic flip plate 8. Initially, the white side faces the staff. When the liquid level rises, the magnetic flip plate 8 changes from white to red. When the liquid level falls, the magnetic flip plate 8 turns back to white. The junction of the red and white magnetic flip plates 8 is the actual height of the medium liquid level in the container, thereby improving the intuitiveness of the current liquid level.
[0046] Example 5: Based on Example 1, in order to facilitate the discharge of accumulated liquid in the floating cavity 11, the bottom of the main pipe 4 is provided with a mounting flange 9, and the inside of the mounting flange 9 is provided with a drain pipe 10, wherein the drain pipe 10 is connected to the floating cavity 11, and the liquid in the floating cavity 11 is discharged by the drain pipe 10.
[0047] When the equipment is under maintenance or not used for a long time, a small amount of liquid may remain in the floating cavity 11. This liquid can be drained through the drain pipe 10 to prevent the liquid from remaining for a long time, which could lead to the growth of bacteria, corrosion of the equipment, or affect the normal operation of the magnetic float 12.
[0048] Understandably, the mounting flange 9 is assembled at the bottom of the main pipe 4 to seal the floating cavity 11. When the mounting flange 9 is removed, the floating cavity 11 can be opened to facilitate the removal of the magnetic float 12.
[0049] In summary, based on Examples 1 to 5, the working steps of the liquid level detection and discharge mechanism for the compressor unit separator tank are as follows:
[0050] The liquid level in the storage cavity is monitored by the rising height of the magnetic float 12 in the main pipeline 4. When the liquid level reaches a preset height, the magnetic float 12 contacts the magnetic control switch, triggering the control unit to send an electrical signal, opening the drain valve, and initiating the automatic discharge process. As the liquid in the storage cavity is discharged, the liquid level gradually decreases, and the magnetic float 12 descends accordingly. When the liquid level drops to a certain level, the magnetic float 12 disengages from the magnetic control switch, the control unit receives a stop signal, the drain valve closes, and the liquid discharge stops. The entire process requires no manual intervention, achieving automatic detection and discharge of liquid in the separator, ensuring the safe and stable operation of the separator.
