Problems solved by technology

Since the end of the soft film membrane close to the permeable pipe is clamped and fixed by the positioning rings on both sides, when the soft film film shakes, the part of the film film clamped by the positioning ring is subject to great stress, resulting in long-term and high-frequency vibration. Damage the strength and quality of this part of the soft film membrane, which is not conducive to the smooth filtration of water by the soft film membrane, but also easily reduces the sealing between the positioning ring and the soft film membrane

Embodiment 1

[0047] Such as Figure 1-Figure 6 As shown, a kind of cushioning device for film film of the present invention and a sewage filtration module with the buffering device include a positioning ring 1, and a vibration-damping ring 2 is set on the side wall of the positioning ring 1, and the vibration-damping ring The axis of 2 is concentric with the axis of positioning ring 1, and elastic members 3 are arranged on the end faces of vibration damping ring 2.

[0048] On the permeable pipe, two adjacent positioning rings 1 fix and clamp the film between them, so the positioning ring 1 is located between the two adjacent film films, and the elastic member 3 is far away from the damping ring One end of 2 is in contact with the corresponding film.

[0049] When the film shakes, due to the setting of the elastic member 3, it reduces the shaking amplitude of the part of the film close to the positioning ring, and buffers the shaking, reducing the stress on the part of the film clamped by...

Embodiment 2

[0051] This embodiment is based on the first embodiment, and further explains the installation of the damping ring 2 .

[0052] Such as Figure 1-Figure 6 As shown in the present invention, a buffer device for film film and a sewage filtration module with the buffer device, an annular groove 4 is arranged on the side wall of the positioning ring 1, and the axis of the annular groove 4 is aligned with the positioning ring 1 The axes coincide, and the diameter of the groove bottom of the annular groove 4 is consistent with the inner diameter of the damping ring 2, and the end of the damping ring 2 near the axis is inserted into the annular groove 4.

[0053] The setting of the annular groove 4 enables the vibration damping ring 2 to be fixed on the side wall of the annular groove 4, so as to prevent the vibration damping ring 2 from moving along the axis of the positioning ring 1, and then the contact surface between the vibration damping ring 2 and the positioning ring 1 Slidi...

Embodiment 3

[0063] This embodiment is based on Embodiment 1, and further explains the elastic member 3 .

[0064] Such as Figure 1-Figure 6 As shown, the present invention is a cushioning device for a film film and a sewage filtration module with the buffering device, and the elastic member 3 is an air bag, or a rubber strip, or a combination of the above two.

[0065] Further, the end of the elastic member 3 away from the damping ring 2 protrudes outward into a hemispherical surface 10 .

[0066] Further, each end surface of the vibration damping ring 2 is provided with 12 elastic pieces 3 .

[0067] Due to the setting of the elastic member 3, the vibration amplitude of the film film is reduced; therefore, in order to improve the effect of shaking off the slag deposited on the surface in order to improve the aeration of the film film, the vibration frequency of the film film can be increased, and then the original aeration effect can be maintained.

Abstract

The invention discloses a buffering device for flexible sheet membranes and a wastewater filtering module with same, which comprise a positioning ring, wherein a shock-absorbing ring sheathes the sidewall of the positioning ring, the axis of the shock-absorbing ring is concentric with the axis of the positioning ring, and elastic parts are arranged on the end surfaces of the shock-absorbing ring.On a water-permeable pipe, a flexible sheet membrane located in between is fixed and clamped by two adjacent positioning rings, so the positioning ring is located between two adjacent flexible sheet membranes; and moreover, the ends, which are far from the shock-absorbing ring, of the elastic parts are in contact with the corresponding flexible sheet membrane. When the flexible sheet membrane shakes, due to the arrangement of the elastic parts, the shake amplitude of the portion, which is close to the positioning rings, of flexible sheet membrane is decreased and the shaking of the flexible sheet membrane is buffered, consequently, the stress applied on the portion, which is clamped by the positioning rings, of the flexible sheet membrane is decreased, the strength quality of the clamped portion of the flexible sheet membrane is increased, the flexible sheet membrane can smoothly filter water, and the tightness between the positioning rings and the flexible sheet membrane is increased.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a buffer device for soft film membranes and a sewage filtration module equipped with the buffer device. Background technique [0002] Ultrafiltration membrane is one of the earliest polymer separation membranes developed. Ultrafiltration membrane is a microporous filtration membrane with consistent pore size and rated pore size below 0.01 micron. Appropriate pressure is applied to one side of the ultrafiltration membrane to screen out solute molecules smaller than the pore size to separate particles with a molecular weight greater than 500 Daltons (atomic mass units) and a particle size greater than 10 nanometers. [0003] Ultrafiltration membranes are widely used in industry and have become one of the new chemical unit operations. Used in separation, concentration, purification of biological products, pharmaceutical products and food industry; also used in terminal trea...
