[0029] Further, the quick release member 3 includes a mounting groove 31 opened on the upper cover plate 13, a pressing strip 32 arranged in the mounting groove 31, the pressing strip 32 being provided with fastening holes 33 on the surface, and a screw rod 34 arranged on the upper end of the filter element 14; after the screw rod 34 on the upper end of the filter element 14 penetrates through the fastening holes 33, the screw rod 34 is screwed with the pressing strip 32 through a nut, the pressing strip 32 is arranged in multiple groups, the fastening holes 33 arranged on the pressing strip 32 are aligned with the central axis of the water inlet hole 21, a sealing strip 35 is arranged on the lower side of the pressing strip 32, and the diameter of the filter element 14 is smaller than the groove width of the mounting groove 31;

[0030] Reference Figure 4 The upper cover plate 13 is movably arranged on the inner wall of the cylinder body 1, the upper cover plate 13 provides sealing and water outlet passage, prevents the filter element 14 from shaking, and ensures that the filtered fluid can only be discharged from the water outlet hole 22, a plurality of groups of mounting grooves 31 are longitudinally arranged on the upper side of the upper cover plate 13, the cross section of the mounting groove 31 is in the shape of a "convex" character, the pressing strip 32 is movably arranged in the mounting groove 31, the pressing strip 32 presses the upper end of the filter element 14 to prevent shaking, and the multiple groups of filter elements 14 are connected as a whole, and reference Figure 5 The "convex" shape of the mounting groove 31 can ensure that the pressing strip 32 can be embedded in the mounting groove 31, but will not penetrate through the mounting groove 31, the fastening holes 33 are arranged on the surface of the pressing strip 32, the screw rod 34 of the filter element 14 is connected through the fastening holes 33, the pressing strip 32 is pressed and deformed when the nut is screwed, the gap is filled, and the sealing performance is enhanced, the number and spacing of the fastening holes 33 on each pressing strip 32 are consistent with the longitudinal arrangement of the water inlet hole 21, it is ensured that the screw rod 34 of each filter element 14 can accurately penetrate through the fastening holes 33 of the pressing strip 32, the pressing strip 32 can simultaneously fix all the filter elements 14, the number of the fastening holes 33 of the pressing strip 32 is not fixed, but is determined by the number of layers in the longitudinal direction of the water inlet hole 21, the length of the pressing strip 32 must be sufficient to accommodate all the fastening holes 33, the arrangement of the filter elements 14 determines the number and spacing of the fastening holes 33, which determines the length of the pressing strip 32 and the size of the mounting groove 31, and the diameter of the filter element 14 is smaller than the groove width of the mounting groove 31;

[0031] The filter element 14 can freely rotate in the mounting groove 31 to provide space for replacement operation, the segmented fixing of the pressing strip 32 facilitates individual replacement, each group of pressing strips 32 only fixes a small number of filter elements 14 arranged in the longitudinal direction, rather than pressing all 110 filter elements 14 as a whole, the nut of the pressing strip 32 corresponding to the filter element 14 is loosened, since the diameter of the filter element 14 is smaller than the width of the mounting groove 31, the filter element 14 can be rotated in the groove to threadedly separate from the butt joint ring 23, and directly pulled out upward, when a new filter element 14 needs to be installed, only reverse operation is needed, the new filter element 14 is inserted, rotated to threadedly engage, and the corresponding pressing strip 32 is pressed again.

[0032] In reuse, 110 filter cartridges 14 lower end is fastened by screwing on the lower cover plate 12 butt joint ring 23, need to tighten, and the lower end of the filter cartridge 14 bottom contact to the upper side of the lower cover plate 12, ensure that all filter cartridges 14 height uniform, through the bottom rigid connection to limit the position of filter cartridge 14, install the upper cover plate 13, the screw rod 34 of the upper end of the filter cartridge 14 penetrates the installation slot 31 and protrudes, provides a fixed fulcrum for the pressing strip 32, at the same time, the "convex" shaped installation slot 31 limits the moving direction of the pressing strip 32, aligns the fastening hole 33 with the screw rod 34 of the filter cartridge 14, embeds into the installation slot 31, tightens the nut, forces the pressing strip 32 to move downward, extrudes the sealing strip 35, eliminates the risk of vibration of the filter cartridge 14 through double-end fixation, the downward pressure of the pressing strip 32 deforms the sealing strip 35, ensures that the fluid can only be discharged from the center water outlet hole 22, the fluid is guided by the inclined surface of the water inlet hole 21 of the lower cover plate 12, uniformly enters 110 filter cartridges 14, and the filtered fluid is discharged from the water outlet hole 22 in a directional manner.

[0033] Various embodiments, with reference to Figure 6 A top buckle type gland 36 is provided to replace the pressing strip 32, and the application scenarios are: low-pressure filtration systems, and places where filter cartridges 14 need to be frequently and quickly replaced.

[0034] The bottom of the filter cartridge 14 remains unchanged, the lower end of the filter cartridge 14 is still screwed by internal threads on the butt joint ring 23 of the lower cover plate 12, and the top end of the filter cartridge 14 is no longer provided with a screw rod 34, but is provided with a protrusion 37 at the top edge, and the pressing strip 32 on the upper cover plate 13 is replaced by a buckle type gland 36 which is independently provided for each group of longitudinally arranged filter cartridges 14 and can be flipped open, a clamping groove 38 matching the contour of the top of the filter cartridge 14 is formed on the lower side of the gland 36, one end of the gland 36 is rotatably connected to the side edge of the installation slot 31 at the corresponding position through a hinge, and a quick buckle is installed at the other end, which can be locked / loosened by simply pulling.

[0035] However, when the gland 36 is locked, the edge of the clamping groove 38 can press the upper surface of the protrusion 37, and the side surface of the protrusion 37 is constrained from moving radially by the wall of the clamping groove 38, and a sealing strip 35 can also be attached to the lower side of the gland 36.

[0036] The lower end of the filter cartridge 14 is screwed on the bottom butt joint ring 23. The protrusion 37 at the top end of the filter cartridge 14 protrudes upward, lifts the free end of the gland 36 at the corresponding position, puts all the flanges of the filter cartridges 14 in the clamping groove 38 area below the gland 36, presses down the free end of the gland 36, tightens the buckle, and the lower side of the gland 36 is pressed, the edge of the clamping groove 38 presses the flange of the filter cartridge 14, and the sealing strip 35 is deformed to achieve sealing.

[0037] To open the buckle gland 36 of the longitudinal row where the filter cartridge 14 needs to be replaced, only need to pull the buckle and lift the free end. Pinch the flange at the top end of the filter cartridge 14 to be replaced and rotate it to unscrew. After replacing the new filter cartridge 14, close the gland 36 and tighten the buckle.

[0038] The compression strip 32, nut, screw 34 are eliminated, and the opening / closing of the gland 36 is much faster than screwing a nut or removing a compression cap, truly "quick release", no tools required. But the mechanical strength of the gland 36 and the buckle itself is not strong enough to withstand the jacking force under high pressure, the high pressure fluid acting on the inside of the filter element 14 will produce a huge upward thrust, the buckle may be deformed, broken or accidentally pop open, the compression force provided by the buckle is usually less than that of a bolt fastening. At high working pressure, the sealing strip 35 may not be compressed enough or be "blown open", resulting in leakage.

[0039] Finally, it should be pointed out that the methods and devices described in detail above are only embodiments, those skilled in the art can modify these embodiments in different ways, as long as they do not deviate from the scope of the present application.
