Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1 to 6 This utility model is an ultrafiltration machine combining an ultrafiltration membrane and a carbon filter cartridge. By using the carbon filter cartridge body 3 in conjunction with the ultrafiltration membrane cartridge 4, the filtration effect is improved.

[0027] Specifically, there is a housing 1 and a housing 2 connected to its left end face; the interior of the housing 1 is provided with three carbon filter elements 3 arranged in a ring, and the interior of the housing 2 is provided with an ultrafiltration membrane cartridge 4. A sealing frame 7 is provided between the carbon filter elements 3 and the ultrafiltration membrane cartridge 4. The side of the sealing frame 7 is provided with a flow port 701 at the position corresponding to the carbon filter elements 3. The left ends of the multiple carbon filter elements 3 are respectively fixed in the adjacent flow ports 701. The side walls of the housing 1 and the housing 2 are fixed with mounting strips 6. The mounting strips 6 are provided to facilitate the installation of the housing 1 and the housing 2.

[0028] The operation process of this embodiment is as follows: With the above structure, when the liquid is inside the housing 1, the liquid inside the housing 1 will be compressed into the carbon filter body 3, and the impurities in the liquid will be filtered through the carbon filter body 3. The filtered liquid will flow into the housing 2, and at the same time, the liquid will pass through the surface of the ultrafiltration membrane cartridge 4 and enter the interior of the ultrafiltration membrane cartridge 4, thereby improving the filtration efficiency.

[0029] Furthermore, a drain pipe 102 is fixedly connected to the right end face of the housing 1, and a water inlet pipe 101 is fixedly connected to the surface wall of the housing 1. When it is necessary to filter the liquid, the water inlet pipe 101 is opened and the drain pipe 102 is closed. At this time, the liquid can be poured in from the inside of the water inlet pipe 101, so that the liquid can be forced into the carbon filter body 3.

[0030] Example 2

[0031] Please see Figure 2 and Figure 5 Based on Example 1, the use of the snap ring 5 facilitates the disassembly of housing 1 and housing 2, enabling the replacement or cleaning of the ultrafiltration membrane cartridge 4.

[0032] Specifically, the outer side of the sealing frame 7 is fitted with two sealing rings 702 arranged left and right. The two sealing rings 702 abut against the inner walls of the housing 1 and the housing 2 respectively. A snap ring 5 is provided at the position between the housing 1 and the housing 2, and the snap ring 5 is locked to the protrusion at the port position of the housing 1 and the housing 2.

[0033] The operation process of this embodiment is as follows: When it is necessary to disassemble the ultrafiltration membrane cartridge 4 inside the housing 2, the buckle ring 5 can be removed from the housing 1 and the housing 2, so that the housing 1 and the housing 2 can be separated. At this time, the ultrafiltration membrane cartridge 4 inside the housing 2 can be removed, so as to replace or clean the ultrafiltration membrane cartridge 4. Since the sealing ring 702 abuts against the housing 1 and the housing 2 respectively, the sealing work is improved.

[0034] Example 3

[0035] Please see Figure 4 and Figure 6 Based on Example 1, the use of the outer screw cylinder 402 in conjunction with the assembly screw tube 202 facilitates the installation of the ultrafiltration membrane cartridge 4.

[0036] Specifically, a sleeve 403 is fitted on the right end face of the ultrafiltration membrane cartridge 4. Multiple spacers 404 are fixed on the surface of the sleeve 403 in a ring-shaped evenly distributed manner, and the spacers 404 abut against the inner side wall of the housing 2. A positioning frame 401 is fitted on the left end face of the ultrafiltration membrane cartridge 4. An outer screw cylinder 402 that communicates with the inside of the ultrafiltration membrane cartridge 4 is fixed on the left end face of the positioning frame 401. An inner screw tube 201 is fixedly connected to the left end face of the housing 2. An assembled screw tube 202 that is fixedly connected to the inner screw tube 201 is provided inside the housing 2. The outer screw cylinder 402 is spirally arranged inside the assembled screw tube 202.

[0037] The operation process of this embodiment is as follows: With the above structure, when it is necessary to install the ultrafiltration membrane cartridge 4, the sleeve 403 and the positioning frame 401 are directly sleeved on both ends of the ultrafiltration membrane cartridge 4. At the same time, the sleeve 403 and the positioning frame 401 seal the end face of the ultrafiltration membrane cartridge 4, and make the outer screw 402 on the end face of the positioning frame 401 connected to the inside of the ultrafiltration membrane cartridge 4. At this time, the outer screw 402 is rotated inside the assembly screw tube 202, so that the ultrafiltration membrane cartridge 4 can be installed, while passing through the spacer 404.
