Description

Technical Field

[0001] The utility model relates to the technical field of ultrafiltration membranes, in particular to an ultrafiltration membrane cleaning device. Background Art

[0002] Ultrafiltration membrane refers to an artificial permeable membrane used in the ultrafiltration process. It is generally made of polymer materials such as cellulose acetate, cellulose acetate esters, polyethylene, polysulfones and polyamides. It is generally pre-made into various types of membrane components such as tubular, plate, roll, capillary, and then assembled together for use to increase the filtration area and facilitate maintenance. Ultrafiltration membrane is a polymer semi-permeable membrane used in the ultrafiltration process that can separate polymer colloids or suspended particles of a certain size from the solution. Ultrafiltration membranes will adhere to more impurities after use, and in order to ensure efficiency next time, they need to be cleaned.

[0003] The existing ultrafiltration membrane cleaning device includes a soaking tank and a cleaning tank. After the ultrafiltration membrane body is placed in the soaking tank and soaked for a period of time, it is moved to the cleaning tank and rinsed with a large amount of clean water to achieve a cleaning effect.

[0004] However, the existing cleaning method can only clean one ultrafiltration membrane body at a time. After it is moved to the cleaning tank after soaking, there is no ultrafiltration membrane body that needs to be cleaned in the soaking tank. Since the ultrafiltration membrane body needs to be soaked for a certain period of time, this method results in low cleaning efficiency and cannot clean multiple ultrafiltration membrane bodies at the same time. Therefore, an efficient ultrafiltration membrane cleaning device is needed. Utility Model Content

[0007] As an improvement, a first drain valve connected to the first cleaning chamber is provided at the bottom end of the left outer wall of the cleaning box, and a second drain valve connected to the second cleaning chamber is provided at the bottom end of the right outer wall of the cleaning box to facilitate the discharge of cleaning water.

[0008] As an improvement, a vibration plate located at the bottom of the connecting valve is slidably provided in the first cleaning chamber and the second cleaning chamber, and a plurality of ultrasonic transducers connected to the bottom surface of the vibration plate are provided at the bottom of the first cleaning chamber and the second cleaning chamber to promote the cleaning efficiency of the cleaning water and improve the cleaning effect.

[0009] As an improvement, an ultrasonic generator electrically connected to the ultrasonic transducer is fixedly provided on the rear outer wall of the cleaning box, and the ultrasonic generator works in conjunction with the ultrasonic transducer.

[0010] As an improvement, the front outer wall of the cleaning box is provided with a transparent observation window cooperating with the first cleaning cavity and the second cleaning cavity, and the transparent observation window facilitates observation of the release status of the soaking liquid.

[0011] As an improvement, a control panel is provided in the center of the front outer wall of the top plate, and the control panel facilitates the operator to control the device.
