Description

Technical Field

[0001] The utility model relates to water treatment equipment, in particular to a water treatment component using a microporous polytetrafluoroethylene filter tube. Background Art

[0002] With the development of modern manufacturing, the reuse of water resources is gaining increasing attention. Environmental protection also requires that wastewater be treated to meet standards before it can be discharged. There are many types of water treatment equipment, including cartridge-type water purifiers, reverse osmosis water purifiers, ultraviolet disinfection water purifiers, aeration tanks, activated sludge treatment equipment, and membrane separation technology. Membrane separation technology uses membrane separation technology to separate harmful substances from wastewater. The advantage of membrane separation technology is its high efficiency, capable of removing harmful substances such as heavy metals and organic matter from water, and is suitable for seawater desalination. Our company's patented invention, ZL201310257509.X microporous polytetrafluoroethylene filter tube and its manufacturing and use methods, is a filter material suitable for membrane separation water treatment equipment. Although it is currently used, due to the need to increase the filtration area as much as possible, the filter tubes are usually spaced close to each other, which makes it very troublesome to connect the filter tubes to the fixed pipe joints. If there is any negligence, the filter tubes and the fixed pipe joints will easily fall off. A small water treatment equipment has hundreds of filter tubes. Once a filter tube falls off, the untreated water at that location will mix with other treated water at the fallen pipe joint, causing the entire water treatment equipment to fail. Utility Model Content

[0003] The utility model aims to provide a water treatment component using a microporous polytetrafluoroethylene filter tube, which has the advantages of reliable filter tube connection and convenient assembly and disassembly.

[0004] In order to achieve the above technical requirements, the technical solution adopted by the present invention is characterized in that it includes a disc-shaped base and a cover plate matched with the base, and the base and the cover plate are fixed by screws, and a plurality of positioning holes are formed on the base, and the positioning holes are small holes formed on the outer end surface of the base through which the microporous filter tube can pass, and a large hole is formed on the matching surface, and a tapered hole transitions between the small hole and the large hole, and a pipe joint with a through hole in the middle is inserted into the positioning hole, and the front end of the pipe joint is tapered, and the size of the taper is the same as that of the tapered hole, and an outward flange is formed at the rear end of the pipe joint, and a microporous filter tube made of polytetrafluoroethylene is sleeved on the outside of the pipe joint, and the tail end of the microporous filter tube is flattened and fused into a closed state. When the cover plate is fixed to the base, the cover plate presses the flange, and the tapered section at the front end of the pipe joint and the tapered hole press the microporous filter tube sleeved on the pipe joint into the tapered hole, and a water outlet hole is formed on the cover plate, which is opposite to each through hole of the pipe joint, for water filtered by the microporous filter tube to flow out.

[0005] Two annular grooves are formed on the outer circumferential surface of the pipe joint.

[0006] The taper of the conical hole is 30 degrees.

[0007] The base has 51 positioning holes in total.

[0008] The screws are self-tapping screws.

[0009] The base and the cover plate are each formed with 3-4 overlapping connection holes for fixing the water treatment components.

[0010] According to the above scheme, a water treatment component using a microporous polytetrafluoroethylene filter tube is manufactured. When installing the microporous filter tube, first select a microporous filter tube of corresponding specifications (including the size of the micropores, the inner and outer diameters of the tube, the length, etc.) according to the needs, flatten the tail end and fuse it. The front end of the microporous filter tube passes through the positioning hole from the outlet end of the base, and the pipe joint is inserted into the hole at the front end of the microporous filter tube. The pipe joint with the filter tube is inserted back into the positioning hole. Each positioning hole is filled with the pipe joint with the filter tube. Finally, close the cover plate, fix the base and the cover plate together with self-tapping screws, press the cover plate against the flange of the pipe joint, and push the pipe joint into the positioning hole, so that the tapered section at the front end of the pipe joint and the conical hole squeeze and fix the microporous filter tube together. This structure allows the filter tube and the pipe joint to be plugged in without being carried out on the base, leaving more space and allowing them to be plugged in place. As the cover is installed and tightened, the microporous filter tube on the pipe joint is pressed into the conical hole by the pipe joint, thereby ensuring the sealing and connection reliability of the water treatment component. The replacement of the microporous filter tube is also very convenient, so that the water treatment equipment can operate normally for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be further described below with reference to the accompanying drawings and through embodiments.

[0024] Figure 1 、 Figure 2 、 Figure 3 The structure diagram of the water treatment component using a microporous polytetrafluoroethylene filter tube is shown in the figure. It includes a disc-shaped base 1 such as Figure 4 、 Figure 5 、 Figure 6 As shown in FIG. 1 and the cover plate 2 corresponding to the base 1 Figure 7 、 Figure 8 、 Figure 9 As shown, the base 1 and the cover 2 are fixed by self-tapping screws 3. There are 51 positioning holes 4 on the base 1. The positioning holes 4 are small holes 6 for the microporous filter tube 5 to pass through and large holes 7 on the mating surface. The small holes 6 and the large holes 7 are transitioned by a conical hole 8. The taper R of the conical hole 8 is 30 degrees. A pipe joint 10 with a through hole 9 in the middle is inserted into the positioning hole 4. Figure 10As shown, the front end of the pipe joint 10 is tapered, the size of the taper being the same as the taper R of the tapered hole 8. The rear end of the pipe joint 10 is provided with an outward flange 11, and the outer circumferential surface of the pipe joint 10 is provided with two annular grooves 12. These grooves serve to store the extruded material from the microporous filter tube 5 and increase friction when the pipe joint 10 is pressed against the microporous filter tube 5, thereby preventing the filter tube 5 from falling off. A polytetrafluoroethylene microporous filter tube 5 is sleeved on the outside of the pipe joint 10, and the tail end of the microporous filter tube 5 is flattened and fused into a closed state. When the cover plate 2 is fixed to the base 1, the cover plate 2 presses the flange 11 of the pipe joint 10, forcing the pipe joint 10 into the positioning hole 4. The tapered section 13 at the front end of the pipe joint 10 and the tapered hole 8 press the microporous filter tube 5 sleeved on the pipe joint 10 into the tapered hole 8, as shown in FIG. Figure 3 As shown. The cover plate 2 is provided with a water outlet hole 14 corresponding to each through hole 9 of the pipe joint 10, for the water filtered by the microporous filter tube 5 to flow out. The base 1 and the cover plate 2 are each provided with three overlapping connection holes 15 for fixing the water treatment component. When installing the microporous filter tube 5, first pass the front end of the microporous filter tube 5 through the positioning hole 4 from the outer end face of the base 1, and insert the pipe joint 10 into the hole at the front end of the microporous filter tube 5 until it reaches the root of the pipe joint 10. Figure 11 As shown, insert the pipe joint 10 with the microporous filter tube 5 back into the positioning hole 4 in the direction of the arrow. All 51 positioning holes 4 are filled with pipe joints 10 with filter tubes 5. Finally, close the cover 2 and fix the base 1 and the cover 2 together with self-tapping screws 3. Figure 1 、 Figure 2 shown.
