[0023] Embodiment one

[0024] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 And Figure 7 A kind of no-baffle high efficiency filter, including frame body 100 and glass fibre filter element 105,

[0025] Two groups of upper ear plates 101 are symmetrically arranged on the upper four corners of the outer wall of frame body 100,

[0026] Upper ear plate screw groove 102 is arranged in upper ear plate 101 respectively,

[0027] Two groups of lower ear plates 103 are symmetrically arranged on the lower four corners of the outer wall of frame body 100 and vertically inward of two groups of upper ear plates 101,

[0028] Lower ear plate screw groove 104 is arranged in lower ear plate 103 respectively,

[0029] The upper end face of the frame body 100 is stacked with a first fixed net 106 and a second fixed net 111,

[0030] A fiber filter screen 109 is clamped between the first fixed net 106 and the second fixed net 111,

[0031] The outer walls of the four corners of the first fixed net 106 and the second fixed net 111 are respectively provided with a first fixed net ear plate 107 and a second fixed net ear plate 112,

[0032] The first fixed net ear plate 107 and the second fixed net ear plate 112 are respectively provided with a first fixed net ear plate through hole 108 and a second fixed net ear plate screw groove 113,

[0033] The upper ear plate 101, the first fixed net ear plate 107, and the second fixed net ear plate 112 are fixed by the upper ear plate screw groove 102, the first fixed net ear plate through hole 108, and the second fixed net ear plate screw groove 113 through the upper bolt 114,

[0034] The lower end face of the frame body 100 is provided with a third fixed net 115,

[0035] The outer wall of the third fixed net 115 is symmetrically provided with a third fixed net ear plate 116 which is used in cooperation with the lower ear plate 103,

[0036] The third fixed net ear plate 116 is respectively provided with a third fixed net ear plate screw groove 117,

[0037] The lower ear plate 103 and the third fixed net ear plate 116 are fixed by the lower ear plate screw groove 104 and the third fixed net ear plate screw groove 117 through the lower bolt 118.

[0038] The glass fiber filter core 105 is filled into the frame body 100, the four edges of the glass fiber filter core 105 abut against the inner wall of the frame body 100, and the two surfaces of the glass fiber filter core 105 respectively abut against the opposite surfaces of the first fixed net 106 and the third fixed net 115.

[0039] The working principle is:

[0040] (1) Fill the glass fiber filter core 105 into the frame body 100, and clamp the fiber filter screen 109 between the first fixed net 106 and the second fixed net 111;

[0041] (2) The upper ear plate 101, the first fixed net ear plate 107, and the second fixed net ear plate 112 are tightly fixed by the upper bolt 114 through the upper ear plate screw groove 102, the first fixed net ear plate through hole 108, and the second fixed net ear plate screw groove 113;

[0042] (3) The lower lug 103 and the third fixed net lug 116 are fixed by the lower bolt 118 through the lower lug screw slot 104 and the third fixed net lug screw slot 117.

[0043] When the glass fiber filter core 105 and the fiber filter screen 109 need to be replaced, the upper bolt 114 is directly unscrewed, the first fixed net 106 and the second fixed net 111 are moved away from the frame body 100, the glass fiber filter core 105 is replaced with a new one, and the first fixed net 106 and the second fixed net 111 are separated to replace the new fiber filter screen 109.

[0044] Example Two

[0045] On the basis of Example One, the baffle-free high-efficiency filter further comprises a circular hollow grommet 110 arranged between the opposite surfaces of the first fixed net lug 107 and the second fixed net lug 112 and sleeved on the upper bolt 114; wherein the circular hollow grommet 110 is made of metal or rubber or nylon.

[0046] The above design can play the role of fastening the gasket and realize the relative fastening of the first fixed net lug 107 and the second fixed net lug 112. At the same time, when the fiber filter screen 109 adopts a crimped fiber filter screen, it can prevent the fiber filter screen 109 from being compressed during assembly (so that it has a certain filtering and adsorbing space) and reduce the filtering efficiency.

[0047] In addition, preferably, the first fixed net 106, the first fixed net lug 107, and the first fixed net lug through hole 108 are integrally formed of alloy stainless steel; the second fixed net 111, the second fixed net lug 112, and the second fixed net lug screw slot 113 are integrally formed of alloy stainless steel; and the third fixed net 115, the third fixed net lug 116, and the third fixed net lug screw slot 117 are integrally formed of alloy stainless steel.

[0048] The above design is durable, long in service life, and has a certain toughness strength, and accordingly plays a role in enhancing the strength of the frame body 100 after assembly.

[0049] In addition, preferably, the frame body 100, the first fixed net 106, the second fixed net 111, and the third fixed net 115 are the same size and do not block the incoming / outgoing air, ensuring efficient filtering function.

[0050] The baffle-free high-efficiency filter of the structure is suitable for use in new air system, medicine, coating, semiconductor, large-scale breeding farm, dust-free workshop, and other filtering systems or equipment.
