Description

Technical Field

[0001] The utility model belongs to the technical field of scale-inhibiting filter elements, and in particular relates to a scale-inhibiting carbon membrane composite filter element barrel. Background Art

[0002] Scale-inhibiting carbon membranes can block, remove scale, and filter substances in water that may cause fouling, and have been applied in actual water purification and scale prevention treatment. Antibacterial ultrafiltration filter elements are equipment components used for water purification. They use ultrafiltration membrane technology to effectively filter and block tiny impurities in water. At the same time, they are equipped with an antibacterial coating to inhibit, sterilize, and ultrafilter water. For example, scale-inhibiting carbon rod filter elements, carbon rod composite filter elements, and filter element components for quality-separation ultrafiltration water purifiers manufactured by Huizhou Yinjia Environmental Protection Technology Co., Ltd.

[0003] However, during actual use, when water with a certain pressure enters the anti-scaling carbon rod filter element or other filter elements, this type of filter element product will have a greater impact on the anti-scaling carbon rod filter element or other filter elements, reducing the scale inhibition ability of the anti-scaling carbon rod filter element, and sometimes even causing the water inlet end of the anti-scaling carbon rod filter element or other filter elements to be cracked or damaged, resulting in a significant reduction in the service life of the anti-scaling carbon rod filter element or other filter elements; in addition, when the water impact force is too large, the antibacterial layer on the surface of the filter element will detach or peel off, causing the filter element to lose its antibacterial effect and even cause water pollution. Therefore, we propose a composite filter element barrel that can effectively reduce water impact and has both scale inhibition and antibacterial properties. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a scale-inhibiting and antibacterial composite filter cartridge barrel that can overcome the above problems or at least partially solve the above problems.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a scale-inhibiting carbon membrane composite filter cartridge barrel, comprising: cover connectors installed at both ends of the outer barrel shell, the cover connectors having a right cover connector and a left cover connector, the right cover connector being connected to an external water inlet pipe, the left cover connector being connected to an external water outlet pipe, the external water inlet pipe being able to divert external water into the outer barrel shell, and the external water outlet pipe being used to discharge water in the outer barrel shell,

[0006] The outer barrel shell is provided with a disc, a carbon membrane, a perforated partition assembly and a filter core in sequence. The disc is installed in the outer barrel shell near the right cover connector. The carbon membrane can prevent scale from flowing into the outer barrel shell.

[0007] The filter core has an antibacterial layer on its surface, which can effectively inhibit the water that permeates from the filter core and the water in the outer barrel shell.

[0008] The perforated partition assembly is a detachable perforated partition assembly. Through the detachable perforated partition assembly, the scale inhibition effect of the carbon membrane body on the water retained in the front section of the outer barrel shell can be improved, and the lateral impact of the water in the front section of the outer barrel shell on the filter core can be reduced, thereby preventing the antibacterial layer on the surface of the filter core from detaching or peeling off due to excessive impact force.

[0009] Furthermore, it also includes: a sealing ring member, wherein the sealing ring member includes a left sealing ring member and a right sealing ring member, the left sealing ring member is mounted on the inner side wall of the left cover connecting member, and the right sealing ring member is mounted on the inner side wall of the right cover connecting member.

[0010] There are annular concave areas on the outside of both ends of the outer barrel shell. The annular concave area on the outside of the left end of the outer barrel shell matches and corresponds to the left sealing ring part on the inner wall of the left cover connector, and the annular concave area on the outside of the right end of the outer barrel shell matches and corresponds to the right sealing ring part on the inner wall of the right cover connector, so as to prevent side leakage of water from occurring at the connection area between the cover connector and the outer barrel shell.

[0011] Preferably, the sealing ring is made of silicone.

[0012] Furthermore, the disc is made of composite ceramic material and has a through hole. The position of the through hole corresponds to the position of the end of the external water inlet pipe on the right cover connector, so that water passing through the external water inlet pipe can flow smoothly into the outer barrel shell.

[0013] Furthermore, the disc has hemispherical grooves, and the number of the hemispherical grooves is an integer greater than one.

[0014] An integer number greater than one of the hemispherical grooves is evenly distributed on the disc with the through hole on the disc as the center. The hemispherical grooves can weaken the impact force of the water flowing into the outer barrel shell through the external water inlet pipe, extend the residence time of the water in the carbon membrane body at the rear of the disc, and improve the scale inhibition ability and service life of the carbon membrane body at the rear of the disc.

[0015] Preferably, the carbon membrane body comprises a composite microfiltration membrane body and a filtration kit, and the filtration kit is sleeved on the outer surface of the composite microfiltration membrane body.

[0016] Furthermore, the composite microfiltration membrane body is made of organic-inorganic hybrid slightly soluble scale-inhibiting solid material, polyurethane and activated carbon, and the composite microfiltration membrane body is a scale-inhibiting activated carbon composite microfiltration membrane body.

[0017] The filter kit is a leaky filter kit with an antibacterial layer coated on its surface. The filter kit is detachably mounted on the outside of the composite microfiltration membrane body to inhibit bacteria and filter water passing through the composite microfiltration membrane body.

[0018] Furthermore, the perforated baffle assembly comprises an upper baffle and a lower baffle that are detachably connected. The upper baffle is arranged at the bottom of the carbon membrane body, and the lower baffle is located outside the upper baffle. There is a gap between the upper and lower baffles. A filter core is provided on the outer side of the rear section of the lower baffle. The outer diameter of the upper baffle matches the outer diameter of the bottom of the carbon membrane body.

[0019] There is a C-shaped through hole in the area near the outer boundary of the upper partition. When water enters the upper partition through the carbon membrane body, the C-shaped through hole can reduce the lateral impact of the water in the front section of the outer barrel shell on the lower partition and the filter element in the rear section of the lower partition.

[0020] There is a '3'-shaped through hole near the center of the lower partition. The lower partition is located outside the inlet end of the filter core. The outer diameter of the lower partition matches the outer diameter of the inlet end of the filter core.

[0021] When water passes through the upper partition and enters the lower partition, the '3'-shaped through holes can evenly distribute the water, reducing the impact of water on the filter element and preventing the antibacterial layer on the surface of the filter element from detaching or peeling off due to excessive impact.

[0022] Preferably, the upper partition and the lower partition are both made of composite ceramic material.

[0023] Furthermore, the filter core has filtering micropores on the surrounding side surfaces, and the bottom of the filter core has no holes. The filter core is arranged in the area of ​​the outer barrel shell adjacent to the left cover connector. The water filtered and antibacterial by the filter core can flow out from the external water outlet pipe on the left cover connector.

[0024] Furthermore, it also includes: a branch pipe joint, the outer barrel shell has a perforation on the side, the perforation is located on the side of the outer barrel shell adjacent to the left cover connector, the branch pipe joint is detachably arranged in the perforation on the side of the outer barrel shell, and is used to laterally divert water in the outer barrel shell after being filtered and sterilized by the filter core;

[0025] The branch pipe joint is provided with a water outlet pipe 1, which can realize lateral water outlet or leakage.

[0026] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the existing technology: the utility model uses ceramic disc parts to slow down the impact of water on the carbon membrane body, thereby improving the scale inhibition ability and service life of the carbon membrane body. There is an antibacterial layer on the outer surface of the filter core, which effectively inhibits the water permeating from the filter core and the water at the rear end of the outer barrel shell. At the same time, the device also uses a detachable perforated partition group to further improve the scale inhibition effect on the water retained in the front end of the outer barrel shell, and reduce the lateral impact of the water at the front end of the outer barrel shell on the filter core, thereby preventing the antibacterial layer on the surface of the filter core from detaching or peeling off due to excessive impact force.

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0037] Example 1:

[0038] Reference Figures 1-6A scale-inhibiting carbon membrane composite filter cartridge barrel, comprising: cover connectors mounted at both ends of an outer barrel shell 2, the cover connectors comprising a right cover connector 1 and a left cover connector 3, the right cover connector 1 being connected to an external water inlet pipe 4, the left cover connector 3 being connected to an external water outlet pipe 5, the external water inlet pipe 4 being capable of diverting external water into the outer barrel shell 2, the external water outlet pipe 5 being used to discharge water from the outer barrel shell 2;

[0039] The outer barrel shell 2 is provided with a disc 7, a carbon membrane body 8, a perforated partition assembly 9 and a filter core 10 in sequence. The disc 7 is installed in the outer barrel shell 2 near the area of ​​the right cover connector 1. The disc 7 is made of composite ceramic material and has a through hole on the disc 7. The position of the through hole corresponds to the position of the end of the external water inlet pipe 4 on the right cover connector 1, so that the water passing through the external water inlet pipe 4 can flow smoothly into the outer barrel shell 2.

[0040] The carbon membrane body can prevent scale from flowing into the outer barrel shell;

[0041] The carbon membrane body 8 comprises a composite microfiltration membrane body 81 and a filter kit 82. The filter kit 82 is mounted on the outer surface of the composite microfiltration membrane body 81 to improve the water shock resistance of the composite microfiltration membrane body 81 and the filtration performance of the carbon membrane body 8.

[0042] The composite microfiltration membrane body 81 is made of organic-inorganic hybrid slightly soluble anti-scaling solid material, polyurethane and activated carbon.

The detachable perforated partition assembly 9 can improve the scale inhibition effect of the carbon membrane body 8 on the water retained in the front section of the outer barrel shell 2, and reduce the lateral impact of the water in the front section of the outer barrel shell 2 on the filter core 10, thereby preventing the antibacterial layer on the surface of the filter core 10 from detaching or peeling off due to excessive impact force;

[0045] The filter element 10 has an antibacterial layer on its surface, which can effectively inhibit the water that permeates from the filter element 10 and the water in the rear end of the outer barrel shell 2. The antibacterial layer can be made of silver ion paint.

[0046] The filter core 10 has filtration micropores on the surrounding side, and no holes on the bottom of the filter core 10.

[0047] When the composite filter cartridge is in use, water enters the disc member 7 in the outer barrel shell 2 through the external water inlet pipe member 4 on the right cover connector 1, then enters the carbon membrane member 8 through the disc member 7 and flows out of the carbon membrane member 8. The carbon membrane member 8 can block, remove scale and filter dirt in the water, and block impurities in the water, allowing water to flow only out of the carbon membrane member 8, thereby achieving the effect of scale prevention and filtration of water.

[0048] Subsequently, the water passing through the carbon membrane body 8 passes through the perforated partition assembly 9 and then enters the filter core 10. When the water permeates out of the filter core 10 and remains in the outer barrel shell 2, the antibacterial layer on the surface of the filter core 10 can effectively inhibit the growth of bacteria in the water in the outer barrel shell 2; then, the water can flow out through the external water outlet pipe 5 on the left cover connector 3 for people to use.
