Description

Technical Field

[0001] This utility model mainly relates to the field of liquid level gauge technology, specifically a fixed cleaning device for membrane tank liquid level gauges. Background Technology

[0002] In industrial fields such as water treatment, wastewater treatment, and chemical production, membrane separation technology has become a core treatment process due to its advantages of high efficiency, low energy consumption, and ease of operation. As a key component of the membrane separation system, the accurate monitoring and stable control of the internal liquid level in the membrane tank directly affects the operating efficiency, separation effect, and service life of the membrane modules. Hydrostatic level gauges are widely used in membrane tank level monitoring scenarios due to their simple and reliable measurement principle (based on the linear relationship between liquid static pressure and liquid level), moderate cost, and strong adaptability. By directly contacting the water body with the detection probe to sense pressure signals, they provide core data support for membrane tank influent and effluent control, equipment linkage, and other related functions.

[0003] However, during the operation of the membrane tank, there are dynamic conditions such as water flow, aeration and stirring, equipment vibration and air pressure fluctuation. Traditional hydrostatic level gauges mostly use simple bracket suspension or single pipe fixation, lacking targeted anti-shake positioning design. At the same time, the level gauge's conveyor line lacks effective limit fixation, and is prone to swinging with the water flow and rubbing against external objects, which not only aggravates signal interference, but may also cause cable wear and breakage, increasing the risk of equipment failure.

[0004] In addition, the membrane tank water contains a large amount of suspended solids, colloidal particles, microorganisms and chemical residues. The detection probe of the hydrostatic level gauge is immersed in the water for a long time, and scale, biofilm adhesion and pollutant deposition are easily formed on the surface. The existing cleaning methods mainly rely on manual periodic disassembly and cleaning or shutdown rinsing, which is cumbersome and labor-intensive. Utility Model Content

[0005] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. It mainly provides a membrane tank level gauge fixing and cleaning device to solve the technical problems mentioned in the background.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A membrane tank level gauge fixing and cleaning device includes a membrane tank, a fixing frame is installed at the top of one side of the membrane tank, and the fixing frame is used to fix a hydrostatic level gauge and a fixing cylinder. The hydrostatic level gauge includes a detection probe, and the detection probe is located inside the cleaning mechanism set inside the fixing cylinder. The detection probe is connected to the level gauge body through a conveyor line, and a clamping plate mechanism for limiting the conveyor line is installed inside the fixing cylinder.

[0007] Preferably, the fixing frame includes a frame body, and the level gauge body is fixedly installed on the top outer side of the frame body, and the inner side of the frame body is connected to the fixing cylinder through a connecting plate.

[0008] Preferably, the fixed cylinder includes an inner cylinder body, and a protective cylinder is fixedly disposed on the outer side of the inner cylinder body.

[0009] Preferably, the cleaning mechanism includes a spray cylinder, and the inner side of the spray cylinder is provided with several sets of spray heads for spraying the detection probe. The spray cylinder is connected to a water supply pipe, and a valve is installed on the water supply pipe.

[0010] Preferably, the clamping plate mechanism includes a clamping plate, and an elastic layer is provided on the side of the clamping plate that contacts the conveyor line. The clamping plate is connected to a handle provided on the outside of the protective cylinder via a drive rod, and a number of springs for applying thrust to the drive rod are provided inside the protective cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The static pressure level gauge and the fixed cylinder are rigidly fixed by the fixing frame. The double-layer structure of the inner cylinder and the protective cylinder of the fixed cylinder provides a stable installation environment for the detection probe, effectively resisting the interference of dynamic conditions such as water flow in the membrane tank and equipment vibration, and avoiding measurement errors caused by probe offset or shaking. At the same time, the clamping plate mechanism uses spring thrust to make the elastic layer fit tightly against the conveyor line, realizing flexible limit of the conveyor line, preventing the cable from swinging and rubbing damage with the water flow, and ensuring the stability of signal transmission. The cleaning mechanism inside the fixed cylinder uses multiple spray heads on the inside of the spray cylinder to spray and clean the detection probe 360°, which can effectively remove scale, biofilm and pollutant deposits on the probe surface. This replaces the traditional manual disassembly and cleaning or shutdown rinsing method, reduces the cumbersome operation and labor intensity, and extends the service life of the level gauge. The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0017] Please refer to the appendix carefully. Figure 1-4 A membrane tank level gauge fixing and cleaning device is provided. A fixing frame 2 is installed on the top of one side of the membrane tank 1. The fixing frame 2 is used to fix a hydrostatic level gauge 3 and a fixing cylinder 4. The fixing frame 2 includes a frame body, which is fixedly connected to the top of the membrane tank 1. The hydrostatic level gauge 3 is fixedly installed on the top of the outer side of the frame body. The inner side of the frame body is connected to the fixing cylinder 4 through a connecting plate.

[0018] The hydrostatic level gauge 3 includes a detection probe 31, which is connected to the level gauge body via a conveyor line 32. The hydrostatic level gauge 3 is existing technology and will not be described in detail.

[0019] The fixed cylinder 4 includes an inner cylinder 41. An impurity screen can be installed at the bottom of the inner cylinder 41. The screen is detachably connected to the inner cylinder 41. A protective cylinder 42 is fixedly installed on the outside of the inner cylinder 41. A connecting plate is fixedly connected to the outside of the protective cylinder 42. The bottom end of the protective cylinder 42 can be detachably connected to the water collection bucket through a flange or a buckle. The water collection bucket is used to collect wastewater generated during the cleaning process, and a wastewater discharge pipe for discharging wastewater is connected to the drain interface at the bottom of the water collection bucket.

[0020] The detection probe 31 is located inside the cleaning mechanism 5 inside the fixed cylinder 4. The cleaning mechanism 5 includes a spray cylinder 51, which is fixedly connected to the inner wall of the inner cylinder 41. Several sets of spray heads are provided inside the spray cylinder 51 for spraying the detection probe 31. The spray tilt angle of the spray head can be adjusted according to the size of the detection probe 31 so that the spray head is located at the part of the detection probe 31 that needs to be cleaned. The spray cylinder 51 is connected to the water supply pipe 52, and a valve is installed on the water supply pipe 52. The water supply pipe 52 is connected to an external water supply device, so that water is supplied to the inside of the spray cylinder 51 through the water supply pipe 52, so that the liquid is sprayed out from the spray head.

[0021] The fixed cylinder 4 is equipped with a clamping plate mechanism 6 for limiting the position of the conveyor line 32. The clamping plate mechanism 6 includes a clamping plate 61, and an elastic layer 62 is provided on the side of the clamping plate 61 that contacts the conveyor line 32. The elastic layer 62 can be made of rubber, thereby providing a certain degree of protection for the conveyor line 32 during the clamping process. The clamping plate 61 is connected to a handle provided on the outside of the protective cylinder 42 via a drive rod 63. The outer end of the handle is connected to the drive plate, and a gripper is provided on the outside of the drive plate for gripping. The gripper can be moved by the drive plate when the hand is gripping it. The gripper is set at the upper end of the membrane tank 1 for easy gripping operation. A limiting rod is set on the outside of the fixing frame 2 to limit the movement direction of the drive plate. A nitrile rubber sealing ring is set at the penetration point between the drive rod 63 and the protective cylinder 42. Several sets of springs 64 are set inside the protective cylinder 42 to apply thrust to the drive rod 63. Mounting plates are set on both sides of the drive rod 63. The mounting plates are located inside the protective cylinder 42. A limiting slide rod is set inside the protective cylinder 42 to limit the movement direction of the mounting plate. The springs 64 apply thrust to the drive rod 63 through the mounting plates.

[0022] The fixing frame 2 and the fixing cylinder 4 are detachably connected to the membrane tank 1, which facilitates the separation of the fixing cylinder 4 from the membrane tank 1 in the later stage, so as to clean the inner wall of the fixing cylinder 4.

[0023] The specific operating procedure of this utility is as follows: First, fix the frame of the fixing frame 2 to the preset installation position at the top of one side of the membrane tank 1. Fix the liquid level gauge body to the top of the outer side of the fixing frame 2. Connect the protective cylinder 42 of the fixing cylinder 4 to the inner side of the fixing frame 2 through the connecting plate, so that the axis of the inner cylinder 41 is perpendicular to the horizontal plane.

[0024] Take out the detection probe 31 of the hydrostatic level gauge 3 and put it into the inner cylinder 41 of the fixed cylinder 4. Slowly lower the detection probe 31 along the axis of the inner cylinder 41 to the preset monitoring depth to ensure that the probe is completely immersed below the liquid surface of the membrane pool 1 and that the bottom is not less than 10cm away from the bottom of the inner cylinder 41. Organize the conveyor line 32 connected to the detection probe 31 along the frame of the fixed frame 2 to avoid the cable from getting tangled or bending too much. Then connect the other end of the conveyor line 32 to the signal interface of the level gauge body to complete the electrical wiring connection.

[0025] During the placement of the conveyor line 32, the gripper is operated to pull the drive rod 63 outward through the grip of the clamping plate mechanism 6. At this time, the drive rod 63 drives the clamping plate 61 to move away from the conveyor line 32. The spring 64 is compressed and generates elastic force. After the conveyor line 32 is placed, the gripper is slowly released, and the spring 64 releases its elastic force to push the drive rod 63 to reset, so that the elastic layer 62 on the clamping plate 61 is tightly attached to the surface of the conveyor line 32, realizing the flexible limitation of the conveyor line 32. After the equipment is started, the hydrostatic level gauge 3 monitors the liquid level of the membrane tank 1 in real time through the detection probe 31. The data is transmitted to the level gauge body for processing and display via the conveyor line 32. The clamping plate mechanism 6 continuously limits the conveyor line 32 to avoid cable swaying caused by water flow disturbance.

[0026] When the detection probe 31 needs to be cleaned, connect the bottom of the protective cylinder 42 to the water collection hopper. The bottom of the water collection hopper is equipped with a wastewater outlet pipe. After the above operation is completed, connect the water supply pipe 52 to the water pump system, open the valve on the water supply pipe 52, and clean water is sprayed onto the surface of the detection probe 31 at a 30°-45° angle through the spray head of the spray cylinder 51. The wastewater generated by the spraying enters the inside of the water collection hopper and is discharged through the wastewater outlet pipe.

[0027] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
