Description

Technical Field

[0001] This utility model relates to the field of water purification membrane technology, and in particular to a water purification membrane cleaning device. Background Technology

[0002] Water purifier membranes are the core components of water purifiers. They remove impurities, bacteria, viruses, heavy metals and other harmful substances from water through physical filtration or membrane separation technology. According to filtration precision, they can be divided into ultrafiltration membranes, nanofiltration membranes and reverse osmosis membranes (RO membranes). Different membrane technologies have their own advantages and disadvantages, and the selection should be based on water quality requirements, operating costs and ease of maintenance.

[0003] In existing technologies, water purification membranes need to be cleaned regularly. However, most of the cleaning of water purification membranes is done manually, which is time-consuming, labor-intensive, and inconvenient.

[0004] Therefore, we propose a water purification membrane cleaning device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where cleaning water purification membranes mostly relies on manual cleaning, which is time-consuming, labor-intensive, and inconvenient. Therefore, this invention proposes a water purification membrane cleaning device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The water purification membrane cleaning device includes: The box has a water inlet pipe fixed on the top inner wall, multiple nozzles at the bottom of the water inlet pipe, and the top of the water inlet pipe extends to the outside of the box and connects to the water supply pipe. A control panel is embedded in the top of the box. The first rotating shaft and the second rotating shaft are rotatably connected to the inner walls of the two sides of the box body, respectively. The outer wall of the second rotating shaft is provided with a guide groove. The second rotating shaft is slidably fitted with a sliding sleeve through the guide groove. The outer wall of the second rotating shaft is threaded with an adjusting sleeve. The adjusting sleeve and the sliding sleeve are rotatably connected. The opposite sides of the first rotating shaft and the sliding sleeve are provided with positioning parts for installing the water purification membrane. The cleaning mechanism, located inside the housing, is used to scrub the surface of the water purification membrane.

[0007] In one possible design, the cleaning mechanism includes two guide plates fixed to the inner wall of one side of the housing, a fixed plate fixed to the outer wall of the first rotating shaft, and a cleaning plate disposed inside the housing. One side of the cleaning plate has two L-shaped guide blocks integrally formed, which are slidably connected to the two guide plates respectively. The other side of the cleaning plate is provided with bristles. A roller is rotatably connected to one side of the cleaning plate. One side of the fixed plate has multiple protrusions integrally formed in a ring, which cooperate with the roller. Hooks are fixed to one side of the cleaning plate and one side of the inner wall of the housing, and a tension spring is provided between the two hooks.

[0008] In one possible design, the positioning element includes a connecting sleeve fixed to one end of the sliding sleeve or one end of the first rotating shaft. A plurality of positioning blocks are integrally formed on one side of the connecting sleeve and distributed in a ring. A sealing ring is sleeved on the outer side of the plurality of positioning blocks.

[0009] In one possible design, a door is hinged to one side of the box, a drain pipe is fixedly connected to one side of the box, and a baffle is provided on the bottom inner wall of the box.

[0010] In one possible design, a connecting block is fixed to the inner wall of one side of the housing, a plug rod is inserted through the surface of the connecting block, and a plug hole is opened on the outer wall of the second rotating shaft, with the bottom end of the plug rod located in the plug hole.

[0011] In one possible design, a shield and a motor are fixed to one side of the outer wall of the housing, with the motor located inside the shield and the output shaft of the motor and the first rotating shaft coaxially fixed.

[0012] In this application, during use, open the box door, insert the insertion rod into the insertion hole to prevent the second rotating shaft from rotating, and facilitate the adjustment of the sliding sleeve. Then, hold the water purification membrane with your left hand and align one end of the water purification membrane with the positioning component on the first rotating shaft, specifically, aligning the positioning block with the sealing ring. Then, rotate the adjusting sleeve with your right hand. The adjusting sleeve causes the sliding sleeve and positioning component to slide, so that the other end of the water purification membrane aligns with the positioning block and sealing ring. The sealing ring prevents impurities from flowing into the water purification membrane. After the water purification membrane is installed, remove the insertion rod to facilitate the rotation of the second rotating shaft. Then close the box door and use the water supply pipe to feed water in... Water is filled into the pipe, and the water flow is sprayed out through the nozzle to rinse the surface of the water purification membrane. The motor is started using the control panel. The motor drives the first rotating shaft, positioning component, water purification membrane, sliding sleeve and second rotating shaft to rotate synchronously. The rinsing water flow, together with the bristles, cleans the outer wall of the water purification membrane. At the same time, the first rotating shaft drives the fixed plate and protrusion to rotate, which in turn pushes the cleaning plate to slide laterally a certain distance. Under the pull of the tension spring, the cleaning plate and bristles can move back and forth, improving the cleaning effect on the water purification membrane. The rinsed water flows out from the drain pipe, which can be connected to a pipe to guide the water flow elsewhere. To clean the brush bristles, separate the tension spring from the hook on the cleaning plate, then move the cleaning plate away from the guide plate to remove it. Then clean the impurities attached to the brush bristles.

[0013] Beneficial effects: In this utility model, the water purification membrane cleaning device can automatically flush and clean the water purification membrane through the setting of positioning parts, first rotating shaft and second rotating shaft and other structures. It is simple and convenient to operate and saves people's energy. In this utility model, the water purification membrane cleaning device, through the setting of structures such as guide plate, guide block and cleaning plate, allows people to easily disassemble the cleaning plate to clean and maintain the impurities attached to the bristles, ensuring the cleaning effect on the subsequent water purification membrane. This invention can automatically rinse and clean the water purification membrane. It is simple and convenient to operate, saving people's energy. It also allows people to easily disassemble the cleaning plate to clean and maintain the impurities attached to the bristles, ensuring the cleaning effect on the subsequent water purification membrane.
