Description

Technical Field

[0001] This utility model relates to the technical field of UF membrane cleaning devices, and in particular to a UF membrane cleaning device with a circulating cleaning function. Background Technology

[0002] UF membranes can be divided into inorganic and organic membranes based on their materials. Organic membranes are mainly made of polymer materials, such as cellulose acetate, aromatic polyamides, polyethersulfone, and polyvinylidene fluoride. Among inorganic membranes, ceramic ultrafiltration membranes are widely used in household water purifiers. Ceramic membranes have a long lifespan and are corrosion-resistant, but the water may have an earthy taste, affecting the palatability. They are also prone to clogging and difficult to clean. UF membranes, or ultrafiltration membranes, have a rated pore size range of 0.01 microns and are widely used in water filtration. Household water purifiers typically use UF hollow fiber membranes. To enable UF membranes to be reused, they can be cleaned and regenerated.

[0003] Announcement No.: CN220444536U A high-efficiency UF membrane cleaning device includes a housing. Two drive cylinders are vertically and symmetrically arranged on the outer wall of the housing. Each drive cylinder has a connecting block at its output end. A top cover is provided on one side of each connecting block. A reduction motor is mounted on the upper surface of the top cover. The output shaft of the reduction motor passes through the interior of the top cover and is connected to a transmission rod. A fixed plate is provided on the outer wall of the transmission rod. A movable plate is located above the fixed plate and near the top cover. Limiting holes are provided on the inner walls of both the fixed plate and the movable plate. This invention uses a reduction motor to drive the transmission rod to rotate. Through a sliding groove on the movable plate, and with the cooperation of connecting parts, the movable plate can rotate, ensuring the normal movement of the UF membrane and cleaning it. An ultrasonic generator can generate ultrasonic waves, producing high-frequency vibrations per second, achieving high-efficiency cleaning of the UF membrane. However, in use, the dirt washed off the UF membrane tends to accumulate and settle on the bottom surface inside the cleaning cylinder, affecting the use of the cleaning device, requiring improvement. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0005] This utility model adopts the following technical solution: a UF membrane cleaning device with a circulating cleaning function, including a mounting base, on the surface of which a liquid storage tank, a circulating pump and a cleaning cylinder are fixedly mounted. An inlet pipe and a drain pipe are fixedly mounted on the surface of the cleaning cylinder. A first motor is fixedly mounted on the bottom surface of the cleaning cylinder. A first rotating rod is fixedly mounted on the output end of the first motor. A fan blade, a scraper and a cleaning brush are fixedly mounted on the surface of the first rotating rod. A cylinder cover is installed on the top of the cleaning cylinder. A second motor is fixedly mounted on the surface of the cylinder cover. A second rotating rod is fixedly mounted on the output end of the second motor. A support plate is fixedly mounted on the bottom end of the second rotating rod. An upper fixed plate and a lower fixed plate are slidably connected to the surface of the second rotating rod. Limiting holes are formed on the lower surface of the upper fixed plate and the upper surface of the lower fixed plate. A fan-shaped groove is formed on the surface of the lower fixed plate. A convex ring is fixedly mounted on the inner wall of the cleaning cylinder, and the lower fixed plate is located above the convex ring.

[0006] Preferably, the outlet of the storage tank is connected to the inlet of the circulation pump, and the outlet of the circulation pump is connected to the inlet pipe of the cleaning cylinder. Here, by connecting the storage tank, the circulation pump, and the cleaning cylinder, a closed-loop circulation system is formed, enabling the reuse of the cleaning solution, reducing waste and operating costs. Furthermore, the circulation pump provides continuous and stable pressure, ensuring uniform distribution of the cleaning solution within the cleaning cylinder and improving cleaning efficiency.

[0007] Preferably, the scraper and cleaning brush are circumferentially distributed on the surface of the first rotating rod, and are arranged in an alternating pattern, with the fan blade positioned above the scraper and cleaning brush. This arrangement facilitates cleaning the bottom of the cleaning drum using the scraper and cleaning brush, allowing impurities and dirt to be discharged along with the cleaning fluid from the drain pipe, thus preventing impurities and dirt from settling at the bottom of the cleaning drum.

[0008] Preferably, a filter screen is fixedly installed inside the fan-shaped groove. This allows for the filtration of impurity particles washed off the UF membrane, preventing large particles from entering the drain pipe and causing blockage.

[0009] Preferably, an ultrasonic generator is fixedly installed at the bottom of the cleaning cylinder. Two sets of ultrasonic generators are distributed on either side of the first motor. Here, the ultrasonic generators generate a cavitation effect through high-frequency vibration, which can rapidly decompose dirt on the UF membrane surface.

[0010] Preferably, a connecting block is fixedly installed on the side of the cylinder cover, and a cylinder is fixedly installed on the surface of the cleaning cylinder. The output end of the cylinder is fixedly connected to the bottom surface of the connecting block, and there are two sets of cylinders, which are symmetrically distributed on the surface of the cleaning cylinder. Here, the cylinders make the opening and closing of the cylinder cover more convenient, increase the degree of automation, and reduce the intensity of manual operation. In addition, when the cylinder cover is opened, the lower and upper fixed plates can be lifted upwards by the support plate, which not only facilitates the removal of the UF components but also makes it easier for personnel to clean the filter screen in the fan-shaped groove.

[0011] Preferably, a sealing strip is fixedly installed on the bottom surface of the cylinder cover, and a sealing groove is formed on the top of the cleaning cylinder, with the sealing strip inserted inside the sealing groove. Here, the sealing strip inserted inside the sealing groove can effectively prevent the cleaning fluid from leaking, maintain the pressure and liquid environment inside the cleaning cylinder, and ensure the stability of the cleaning process. At the same time, the sealing structure can also reduce the entry of external contaminants into the cleaning cylinder, improving the cleanliness and durability of the equipment.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, a closed-loop circulation system is formed by connecting the liquid storage tank, the circulating pump, and the cleaning cylinder. The cleaning liquid can be reused, which greatly reduces the waste of cleaning liquid and operating costs. The first motor drives the first rotating rod to rotate, and the fan blades installed on the first rotating rod agitate the cleaning liquid. The scraper and cleaning brush are arranged alternately to perform mechanical cleaning, which can efficiently remove dirt from the bottom of the cleaning cylinder and prevent dirt from accumulating at the bottom of the cleaning cylinder. The filter screen installed in the fan-shaped groove on the lower fixed plate can effectively filter the sewage liquid and prevent large particles of impurities from entering the drain pipe and causing blockage.

[0014] 2. In this utility model, the cylinder cover is automatically opened and closed by two sets of symmetrically distributed cylinders, which reduces the intensity of manual operation and improves the convenience of operation. The sealing strip and the sealing groove work together to ensure that the liquid environment inside the cleaning cylinder is completely sealed, effectively preventing the cleaning fluid from leaking and blocking external pollutants from entering the cleaning cylinder. The convenient opening and closing of the cylinder cover also makes it easy for personnel to clean the filter screen and remove components, greatly improving the equipment maintenance efficiency and operational safety.
