Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, and more specifically to an automatic lamination backwashing filtering device which is convenient for replacing a filter element. Background Art

[0002] The fully automatic laminated filter is the same as other filters, which is composed of a filter housing and a filter element. The filter housing material is generally plastic, stainless steel, or plastic-coated carbon steel, and there are many shapes. The filter element is in the shape of a hollow cylinder, which is composed of many annular plastic sheets with micron-grade regular triangle grooves on both sides assembled on a central frame.

[0003] The existing fully automatic laminated filter has a fixed height during installation, and the pipes to be connected need to be changed by themselves for alignment and connection, which is troublesome to install and has low applicability. The existing patent is a fully automatic laminated backwashing filter device. The patent authorization number CN215310567 provides a liftable base frame at the bottom of the backwashing filter body, which is driven and lifted by threaded engagement, so that the height of the utility model can be adjusted by the staff to facilitate the connection and installation of the pipes.

[0004] When the laminated filter element needs to be replaced, the filter element needs to be removed and then the pressing lock nut is turned. Since the pressing lock nut and the mounting frame are screwed together, it is cumbersome to disassemble and assemble the laminated elements. For example, the filter element in patent authorization number CN215310567 usually adopts the pressing nut crimping method. Therefore, we propose an automatic laminated backwashing filter device that is easy to replace the filter element to solve the above-mentioned problems. Utility Model Content

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0031] Example:

[0032] See also Figure 1-6 , an automatic lamination backwashing filter device for easy replacement of filter elements, comprising a connector 1, a cover 2 installed on the top of the connector 1, a clamp 3 installed between the cover 2 and the connector 1, a mounting frame 4 installed on the inner side of the cover 2 and a lamination body 5 sleeved on the outer side of the mounting frame 4, a guide notch 6 is symmetrically opened on the top of the mounting frame 4, and a positioning hole 7 is opened below the guide notch 6;

[0033] The top of the mounting frame 4 is detachably connected with a clamping cover 8, the inner side of the clamping cover 8 is fixedly connected with a connecting frame 9, both ends of the connecting frame 9 are fixedly connected with guide posts 10, and the guide posts 10 are slidably connected with a positioning claw 11 which is arranged in a C-shaped structure and the bottom end of which is engaged with the positioning hole 7, and one side of the positioning claw 11 is provided with a spring 12 which is sleeved on the outside of the guide post 10, and one end of the spring 12 is in contact with the positioning claw 11;

[0034] The top of the compression cover 8 is detachably connected with a cover 15;

[0035] It should be noted that when the automatic laminated backwashing filter device which is convenient for replacing the filter element is used, the clamp 3 is first removed, then the cover shell 2 is removed, and then the mounting frame 4 is removed together with the laminated body 5 as a whole. The cover 15 is removed, and the positioning claw 11 is moved toward the guide column 10 to make the bottom end of the positioning claw 11 disengage from the positioning hole 7, so that the clamping cover 8 is removed, and the laminated body 5 is removed and replaced. Then, the bottom end of the positioning claw 11 is abutted against the bottom of the guide notch 6. Under the action of the downward pressure, the positioning claw 11 cooperates with the guide column 10 to slide and compress and deform the spring 12. The positioning claw 11 is guided by the guide notch 6 to correspond to the positioning hole 7, and then the elastic force of the spring 12 is used to make it engage, and then the cover 15 is installed. The operation is very convenient and the replacement of the laminated body 5 can be completed quickly.

[0036] like Figure 3 , Figure 5 As shown, a boss is integrally formed on the upper surface of the compression cover 8, and a sealing rubber ring 14 is embedded on the outer wall of the boss and is connected to the inner wall of the bottom opening of the cover 15;

[0037] It should be noted that by using the sealing rubber ring 14 to fill the gap at the junction of the pressing cover 8 and the cover 15, it is possible to prevent unretained impurities from seeping through, while at the same time improving the bonding force between the pressing cover 8 and the cover 15 so that it is not easy to fall off.

[0038] like Figure 3 As shown, the lower surface of the compression cover 8 abuts against the laminate body 5 at the top end of the mounting frame 4;

[0039] It should be noted that the stacked body 5 is guaranteed to have an interception effect on impurities in water.

[0040] like Figure 6 As shown, a guiding slope is provided at the bottom of the positioning claw 11;

[0041] It should be noted that, by abutting the inclined surface at the bottom end of the positioning claw 11 with the bottom of the guide notch 6, the positioning claw 11 cooperates with the guide column 10 to slide and compress and deform the spring 12 under the action of downward pressure. The positioning claw 11 is guided by the guide notch 6 to correspond to the positioning hole 7, and then the elastic force of the spring 12 is used to engage it, which facilitates the assembly of the compression cover 8.

[0042] like Figure 5 As shown, the top side wall of the positioning claw 11 fits with the inner wall of the connecting frame 9;

[0043] It should be noted that the stability of the positioning claw 11 during the sliding process is ensured, thereby ensuring that the bottom end of the positioning claw 11 can be accurately docked with the positioning hole 7.

[0044] like Figure 5 As shown, a shift block 13 is integrally formed on the top of the positioning claw 11, and the shift block 13 is arranged in a right-angled triangle structure, and an anti-skid convex tooth is integrally formed on the inclined surface of the shift block 13, and a plurality of anti-skid convex teeth are arranged at equal distances;

[0045] It should be noted that the disassembly of the pressing cover 8 is facilitated by providing the shifting block 13 .

[0046] During use: first remove the clamp 3 and then the cover shell 2, then remove the mounting frame 4 together with the laminate body 5 as a whole, remove the cover 15, and move the positioning claw 11 and the guide column 10 toward each other to make the bottom end of the positioning claw 11 disengage from the positioning hole 7, thereby removing the clamping cover 8, remove and replace the laminate body 5, and then abut the bottom end of the positioning claw 11 against the bottom of the guide notch 6, and under the action of the downward pressure, the positioning claw 11 cooperates with the guide column 10 to slide and compress and deform the spring 12, guide the positioning claw 11 through the guide notch 6 to make it correspond to the positioning hole 7, and then use the elastic force of the spring 12 to make it engage, and then install the cover 15.

[0047] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
