Description

Technical Field

[0001] This utility model relates to the field of MBR membrane production technology, and in particular to an integrated online cleaning and testing device for MBR membranes. Background Technology

[0002] MBR ultrafiltration membranes are microporous filtration membranes with a rated pore size range of 0.001-0.02 micrometers. Belonging to the category of polymer separation membranes, they combine membrane separation units with biological treatment units and are applied in wastewater treatment and water resource reuse. They primarily employ flat sheet membranes and hollow fiber membrane structures. During use, MBR membranes require cleaning, necessitating an integrated online cleaning and testing device. This online cleaning device directly cleans the membrane modules during the treatment process and is mainly used in municipal wastewater treatment, industrial wastewater treatment, and greywater reuse systems. Its core function is to remove surface fouling through automated or semi-automated methods to maintain treatment efficiency.

[0003] Current integrated online cleaning and testing devices for MBR membranes can basically meet people's needs, but there are still some problems, as follows: When cleaning the MBR membrane, if the water does not flow, the cleaning efficiency of the MBR membrane is not high enough, and the medicine cannot be completely mixed with the water. Utility Model Content

[0004] The purpose of this invention is to provide an integrated online cleaning and testing device for MBR membranes, which solves the problem that existing integrated online cleaning and testing devices for MBR membranes are difficult to agitate water.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an integrated online cleaning and testing device for MBR membranes, including support legs;

[0006] A support rod is installed at the bottom of the support leg, a water tank is installed at the top of the support leg, a water outlet is installed at one end of the water tank, and a valve is installed at the top of the water outlet.

[0007] A bracket is installed at the top of the water tank, a lifting mechanism is installed at the top of the bracket, a lifting plate is installed at the bottom of the lifting mechanism, and an MBR membrane is installed at the bottom of the lifting plate.

[0008] A water quality sensor is installed at the bottom of the water tank. A stirring mechanism is installed inside the water tank, and the stirring mechanism includes a servo motor installed on one side of the water tank, with a rotating wheel installed on one side of the servo motor.

[0009] In use, the MBR membrane is first positioned at the bottom of the lifting plate. The cylinder then operates to extend and retract the telescopic push rod, which is fixed to the top of the lifting plate via a mounting plate. The extension and retraction of the push rod raises and lowers the lifting plate, which in turn raises and lowers the MBR membrane positioned at the bottom. The MBR membrane can then enter the water tank. Water and chemicals are then mixed inside the tank, allowing the MBR membrane to soak and be cleaned. A water quality sensor monitors and detects the water quality inside the tank. After cleaning, the cylinder operates to discharge the MBR membrane, and a valve controls the outlet, allowing water to be discharged.

[0010] Furthermore, a transmission belt is installed on the outer side of the rotating wheel, a connecting rod is installed on one side of the bottom end of the rotating wheel, a rotating shaft is installed on one side of the top end of the rotating wheel, and a rotating disk is installed on one side of the rotating shaft. The rotation of the rotating wheel can drive the rotating disk to rotate, the rotation of the rotating disk can drive the stirring blade to rotate, and the rotation of the stirring blade can stir the water.

[0011] Furthermore, a stirring blade is installed on one side of the rotating disk, and the stirring blades are arranged at equal intervals on one side of the rotating disk. The rotation of the stirring blades can stir the water.

[0012] Furthermore, the lifting mechanism includes a cylinder mounted on the top of the bracket, and a telescopic push rod is mounted on the bottom of the cylinder. A mounting plate is mounted on the bottom of the telescopic push rod, and guide rods are mounted on both sides of the top of the lifting plate. The lifting mechanism can adjust the height of the lifting plate.

[0013] Furthermore, the guide rod is telescopic and is symmetrically distributed about the central axis of the lifting plate, and can guide the lifting plate to move up and down.

[0014] Furthermore, a limiting structure is installed at the bottom end of the lifting plate, and the limiting structure includes a fixed plate installed at the bottom end of the lifting plate. Positioning rods pass through both ends of the fixed plate, and a limiting plate is installed on one side of the positioning rod. A threaded rod is installed on one side of the limiting plate. The limiting structure can limit the position of the MBR membrane.

[0015] Furthermore, the outer side wall of the threaded rod is uniformly provided with external threads, and the inner side wall of the fixing plate is uniformly provided with internal threads that cooperate with the external threads. The threaded rod and the fixing plate are threadedly connected, and the rotation of the threaded rod can drive the limiting plate to move.

[0016] Furthermore, the limiting plate has a slider at its top and the lifting plate has a slider at its bottom, forming a sliding structure, and the limiting plate can slide at the bottom of the lifting plate.

[0017] Furthermore, the limiting plates are symmetrically distributed about the central axis of the lifting plate, and the limiting plates are L-shaped, which can fix the MBR membrane.

[0018] Furthermore, an MBR membrane is installed at the bottom of the lifting plate, and the MBR membranes are arranged at equal intervals at the bottom of the lifting plate.

[0019] The integrated online cleaning and testing device for MBR membranes provided by this utility model has the following advantages: the water can be stirred by the stirring mechanism to improve the cleaning effect of the water on the MBR membrane; the MBR membrane can be limited and fixed by the limiting structure; and the MBR membrane can be raised and lowered by the lifting mechanism.

[0020] By installing a rotating wheel on one side of the servo motor, the servo motor drives the rotating wheel to rotate. When the rotating wheel rotates, it drives the rotating wheel at the bottom to rotate via a transmission belt. At the same time, the rotation of the rotating wheel at the bottom can drive the rotation of the connecting rod, which in turn drives the rotating wheel on the other side to rotate. The rotating wheel at the top then drives the rotating disk to rotate along the shaft. The rotation of the rotating disk can drive the stirring blade to rotate, which can agitate the water inside the water tank and make the water flow. The flowing water can improve the cleaning effect of the MBR membrane, thereby achieving the purpose of the integrated online cleaning and testing device for MBR membranes, which facilitates water agitation.

[0021] A fixed plate is installed at the bottom of the lifting plate. The fixed plate and the threaded rod form a threaded connection. Tightening the threaded rod can drive it to move. The movement of the threaded rod can drive the movement of the limiting plate. The limiting plate is L-shaped. The movement of the limiting plate can clamp the MBR membrane in the middle and limit the position of the MBR membrane, which facilitates the installation and removal of the MBR membrane. The positioning rod passes through the fixed plate and can guide the movement of the limiting plate. In this way, the online cleaning and testing integrated device for MBR membranes can be used to limit the position of the MBR membrane. Attached Figure Description
