Description

Technical Field

[0001] This utility model belongs to the technical field of membrane concentration devices, specifically a segmentable membrane concentration device. Background Technology

[0002] A segmented membrane concentration unit is a device based on membrane separation technology. Its core function is to achieve efficient separation, concentration, and purification of solutes in a liquid mixture by combining membrane modules with different structures or functions in segments. It utilizes the selective permeability of membranes (such as reverse osmosis membranes and nanofiltration membranes) to separate solvents (such as water) from solutes (such as salts, organic matter, colloids, etc.) in a solution. The segmented design allows the liquid to gradually pass through membranes with different pore sizes or functions in different membrane segments, thereby improving separation efficiency.

[0003] In existing segmented membrane concentration devices, suspended solids, colloids, organic matter, salts and other substances in the feed solution will gradually be adsorbed or deposited on the membrane surface and in the pores, forming a filter cake layer or gel layer. Protein molecules will accumulate on the membrane surface, resulting in a significant decrease in membrane flux and reducing the efficiency of the device. When the membrane needs to be replaced, the entire device needs to be disassembled, which is time-consuming and labor-intensive, further reducing the efficiency of the device. Summary of the Invention

[0004] The purpose of this invention is to provide a segmentable membrane concentration device that enables uninterrupted filtration during membrane replacement, thereby improving the device's working efficiency. It can also open up the upper and lower sides of the membrane to prevent the fibers in the fiber membrane from becoming entangled or folded due to water flow impact or pressure fluctuations, thus affecting the membrane flux and service life.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A segmentable membrane concentration device is provided, comprising a base, the base including a base plate, a concentration mechanism mounted on the upper surface of the base, the concentration mechanism including a first connecting pipe, a second connecting pipe, a third connecting pipe, and a fourth connecting pipe.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In use, the liquid to be concentrated is added through the feed pipe. After entering the first connecting pipe, the liquid first passes through the first membrane. A support frame is inserted inside the connecting shell, and the first membrane is mounted on the surface of the support frame. There are three support frames. When the membrane needs to be replaced, simply pull out the right-side support frame, install the new membrane on it, and push it back into place. Then pull out the left-side support frame, remove the old membrane, and push it back into place. During the pulling and pulling of the three support frames, the gap between the support frames and the connecting shell is filled by a sealing ring to prevent leakage. The replacement process does not affect filtration. This invention enables uninterrupted filtration during membrane replacement, improving the device's working efficiency.

[0013] When using this invention, first pinch the connecting rods on the top and bottom sides, then put the membrane on the surface of the moving plate. At this time, the left and right sides of the membrane are stretched open. Then, release the connecting rods, and the elastic block fixedly connected to the moving plate will retract. Pull the moving plate up and down to stretch the top and bottom sides of the membrane, thus preventing the fibers in the fiber membrane from getting tangled and folded due to water flow impact or pressure fluctuations, which would affect the membrane flux and service life.

The right connecting shell 301 is fixedly connected to the outer wall of the third connecting pipe 203 and the fourth connecting pipe 204.

A support mechanism 4 is installed on the surface of the support frame 304. The support mechanism 4 includes an elastic block 401. The surface of the elastic block 401 is fixedly connected to the surface of the support frame 304. The liquid to be concentrated is added from the feed pipe 205. After the liquid enters the first connecting pipe 201, it first passes through the first membrane. The support frame 304 is inserted inside the connecting shell 301. The first membrane is installed on the surface of the support frame 304. The membrane material is a nanofiltration membrane. There are three support frames 304. When the membrane needs to be replaced, simply pull out the right support frame 304, install the new membrane on the support frame 304, and push it back to its original position. Then pull out the left support frame 304, remove the original membrane on the support frame 304, and push it back to its original position. During the process of pulling out the three support frames 304, the gap between the support frame 304 and the connecting shell 301 is filled by the sealing ring 303 to prevent leakage. The replacement process will not affect filtration.

[0025] A foot 102 is fixedly connected to the lower surface of the base 101. A connecting plate 103 is fixedly connected to the left side surface of the base 101. A first groove 104 is formed inside the base 101. A heating plate 6 is fixedly connected to the inner wall of the first groove 104. The heating plate 6 generates heat during use, which can control the temperature and improve the concentration speed.

The support frame 304 is fixedly connected to a movable plate 402, and the movable plate 402 is fixedly connected to a connecting rod 403. In use, the connecting rods 403 on the upper and lower sides are pinched first, and then the membrane is placed on the surface of the movable plate 402. At this time, the left and right sides of the membrane are spread apart, and the connecting rods 403 can be released. The elastic block 401 fixedly connected to the movable plate 402 retracts, and the movable plate 402 is pulled up and down to spread the upper and lower sides of the membrane. This prevents the fibers in the fiber membrane from getting tangled and folded due to water flow impact or pressure fluctuations, which would affect the membrane flux and service life. A cleaning mechanism 5 is installed on the right side surface of the connecting plate 103. The cleaning mechanism 5 includes a cylinder 501.

When it is necessary to clean the inside of the fourth connecting pipe 204, the cylinder 501 is activated, causing the push plate 502 fixed at the telescopic end of the cylinder 501 to push towards the pipe cover 207, thus pushing out the residual material inside the fourth connecting pipe 204.

[0026] Working principle: The liquid to be concentrated is added through the feed pipe 205. After entering the first connecting pipe 201, the liquid first passes through the first membrane. A support frame 304 is inserted inside the connecting shell 301. The first membrane is installed on the surface of the support frame 304, and there are three support frames 304. When the membrane needs to be replaced, simply pull out the right support frame 304, install the new membrane on it, and push it back into place. Then pull out the left support frame 304, remove the old membrane from it, and push it back into place. The process of pulling out the three support frames 304 is repeated. During the process, the gap between the support frame 304 and the connecting shell 301 is filled by the sealing ring 303 to prevent leakage. The replacement process will not affect filtration. First, pinch the connecting rods 403 on the upper and lower sides, and then put the membrane on the surface of the moving plate 402. At this time, the left and right sides of the membrane are stretched open. Then, the connecting rods 403 can be released, and the elastic block 401 fixedly connected to the moving plate 402 will retract. Pull the moving plate 402 up and down to stretch the upper and lower sides of the membrane. This prevents the fibers in the fiber membrane from getting tangled and folded due to water flow impact or pressure fluctuations, which would affect the membrane flux and service life.
