Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment equipment technology, specifically to an improved online membrane tube cleaner. Background Technology
[0002] Ceramic membrane cleaning tanks play a vital role in water treatment, including the treatment of various domestic and process water, as well as the purification of industrial wastewater. They effectively remove impurities, pathogens, and organic matter from water, ensuring the safety of the effluent.
[0003] In related technologies, during the long-term continuous operation of ceramic membrane equipment, minute changes such as valve opening and closing actions, backwash pressure, and pump operation can lead to qualitative changes and variations in the set water filling time. This can result in the ceramic membrane cleaner failing to be fully replenished with water, requiring manual opening of the overflow valve periodically to check for full replenishment. If backwashing continues without full replenishment for an extended period, compressed air from the cleaning tank supplying backwash fluid to the ceramic membrane cleaner can directly enter the ceramic membrane cleaner, damaging the ceramic membrane tubes. To address these issues, an improved online membrane tube cleaner is proposed. Utility Model Content
[0004] In view of this, the present invention provides an improved online membrane tube cleaner. The present invention uses an upper tuning fork switch to detect the high liquid level in the tank, thereby controlling the water inlet pipe to stop supplying water to the tank. It uses a lower tuning fork switch to detect the low liquid level in the tank, thereby controlling the water inlet pipe to supply water to the ceramic membrane cleaning tank. When the pressure inside the ceramic membrane cleaner to be backwashed is unbalanced, the exhaust valve can be automatically opened and closed to release the gas in the ceramic membrane cleaner to equalize its internal pressure, thereby avoiding the damage to the ceramic membrane due to pressure loss in the ceramic membrane cleaner to be backwashed. Thus, when the liquid level in the ceramic membrane cleaner is insufficient, water can be replenished in a timely manner.
[0005] To solve the above-mentioned technical problems, this utility model provides an improved online membrane tube cleaner, including a detachable sealing cover on the top of the ceramic membrane cleaning tank, a backwash pipe on one side of the bottom of the ceramic membrane cleaning tank, an upper tuning fork switch on the upper part of the ceramic membrane cleaning tank, a lower tuning fork switch on the lower part of the ceramic membrane cleaning tank, an exhaust valve connected to one side of the top of the sealing cover, multiple lifting components on the outer surface of the sealing cover, and a drain valve at the bottom of the ceramic membrane cleaning tank.
[0006] A flow meter for measuring the flow rate of the backwash pipe is installed at the top of the backwash pipe outlet.
[0007] An inspection window is provided in the middle of the ceramic membrane cleaning tank to check the liquid level inside the tank.
[0008] Each lifting assembly includes a groove installed on the outer top wall of the ceramic membrane cleaning tank. The groove is used to connect the ceramic membrane cleaning tank to a rotating shaft. The rotating shaft is horizontally installed through the groove. The rotating shaft is used to drive the connecting rod to swing and rotate. The connecting head is rotatably installed in the middle of the rotating shaft. The connecting head is used to connect the rotating shaft to the connecting rod. The connecting rod is installed at the upper part of the connecting head. The connecting rod is used to connect the connecting head to the lifting ring. The lifting ring is installed at the top of the connecting rod, which facilitates the lifting of the ceramic membrane cleaning tank.
[0009] The bottom of the ceramic membrane cleaning tank is equipped with multiple connecting blocks, which are used to connect the legs of the ceramic membrane cleaning tank. Each connecting block has a leg at its bottom, which is used to support and fix the ceramic membrane cleaning tank.
[0010] An air inlet pipe is connected to the center of the sealing cover. The air inlet pipe is used to replenish air into the ceramic membrane cleaning tank. A water inlet pipe is located next to the air inlet pipe. The water inlet pipe is used to replenish water into the ceramic membrane cleaning tank. The water inlet pipe is connected to the ceramic membrane cleaning tank. A silencer is located next to the air inlet pipe. The silencer is used to reduce the noise of the ceramic membrane cleaning tank during operation, thereby improving the comfort of the working environment, reducing noise interference to operators, and extending the service life of the equipment. The silencer is connected to the ceramic membrane cleaning tank.
[0011] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:
[0012] 1. The upper tuning fork switch detects the high liquid level in the tank, thereby controlling the water inlet pipe to stop supplying water to the tank. The lower tuning fork switch detects the low liquid level in the tank, thereby controlling the water inlet pipe to supply water to the ceramic membrane cleaning tank. When the pressure inside the ceramic membrane cleaner to be backwashed is unbalanced, the exhaust valve can be automatically opened and closed to release the gas inside the ceramic membrane cleaner to equalize its internal pressure, thereby preventing the ceramic membrane from being damaged due to pressure loss inside the ceramic membrane cleaner to be backwashed. Thus, when the liquid level in the ceramic membrane cleaner is insufficient, water can be added in a timely manner, improving the automation efficiency of the equipment.
[0013] 2. The lower liquid level chamber can prevent the liquid in the storage chamber from flowing down too quickly, which would reduce the speed of the liquid level detection signal. Therefore, when the liquid level drops to the lower liquid level chamber, the low liquid level can be detected quickly. Then, when the lower tuning fork switch detects the low liquid level alarm, the water inlet pipe will automatically replenish water to the ceramic membrane cleaning tank.
[0014] 3. The silencer can reduce the noise of the ceramic membrane cleaning tank during operation, thereby improving the comfort of the working environment, reducing noise interference to operators, and extending the service life of the equipment. Attached Figure Description

Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0021] like Figure 1-4As shown: This embodiment provides an improved online membrane tube cleaner, including a detachable sealing cover 101 on the top of a ceramic membrane cleaning tank 100. Multiple sealing buckles are provided on the outer surface of the sealing cover 101. The upper part of the sealing buckles is connected to the sealing cover 101, and the lower part of the sealing buckles is fixed to the tank body of the ceramic membrane cleaning tank 100. A backwash pipe 102 is provided on one side of the bottom of the ceramic membrane cleaning tank 100, and is welded to the bottom of the ceramic cleaning tank. An external flange is provided externally. An upper tuning fork switch 301 is provided on the upper part of the ceramic membrane cleaning tank 100, and is fixed to the upper pipe wall of the ceramic membrane cleaning tank 100. The upper tuning fork switch 301 is also used to detect the high liquid level at the upper part of the ceramic membrane cleaning tank 100, thereby stopping the liquid supply to the ceramic membrane cleaning tank 100 when the liquid level is high. A lower tuning fork switch 303 is provided on the lower part of the ceramic membrane cleaning tank 100, and is used to detect the high liquid level at the upper part of the ceramic membrane cleaning tank 100. At a low liquid level of 100, an exhaust valve 103 is connected to one side of the top of the sealing cover 101. The exhaust valve 103 can remove air from the tank, which helps to ensure uniform pressure distribution across the entire ceramic membrane surface. This not only improves the filtration efficiency of the ceramic membrane but also increases water production, thereby enhancing the overall performance of the cleaner. During the cleaning process, if the pressure inside the tank exceeds the set range, the exhaust valve 103 will automatically release gas to prevent equipment damage or accidents. The bottom of the exhaust valve 103 has an exhaust pipe that is threadedly connected to the sealing cover 101. The outer surface of the sealing cover 101 is equipped with multiple lifting components 200, which facilitate the lifting and movement of the ceramic membrane cleaning tank 100. A drain valve 107 is located at the bottom of the ceramic membrane cleaning tank 100. The drain valve 107 is used to drain the water inside the ceramic membrane cleaning tank 100. The drain valve 107 is a manual ball valve and is welded to the bottom of the ceramic membrane cleaning tank 100 via a connecting pipe.
[0022] In use, connect the backwash pipe 102 to the backwash port of the ceramic membrane cleaner to be cleaned. The upper tuning fork switch 301 detects the high liquid level in the ceramic membrane cleaning tank 100, and the PLC controls the water inlet pipe 105 to stop supplying water to the ceramic membrane cleaning tank 100 or the air inlet pipe 104 to supply air. The lower tuning fork switch 303 detects the low liquid level in the ceramic membrane cleaning tank 100, and the PLC controls the water inlet pipe 105 to supply water or the air supply pipe to supply air. When the pressure inside the ceramic membrane cleaner to be backwashed becomes unbalanced, the exhaust valve 103 automatically opens and closes, thereby releasing pressure. The gas inside the tank is released to equalize the internal pressure, thereby preventing pressure loss and damage to the ceramic membrane in the ceramic membrane cleaner to be backwashed. The vent on the side of the ceramic membrane, combined with the exhaust valve 103, allows the tank to quickly return to equilibrium. This allows for timely replenishment of water when the liquid level in the ceramic membrane cleaner is insufficient, improving the automation efficiency of the equipment. The automatic control principle of the valves and water pump installed on the water inlet pipe 105 and air inlet pipe 104 is relatively mature in the existing technology. Therefore, those skilled in the art are clear about the self-closing principle of the water pump and valve controlled by PLC, and will not be elaborated on here.

[0030] like Figure 1 , 2 As shown in Figure 4: The bottom of the ceramic membrane cleaning tank 100 is provided with multiple connecting blocks 400. The connecting blocks 400 can be welded and fixed to the tank wall of the ceramic membrane cleaning tank 100.
