Problems solved by technology

[0006] The object of the present invention is to provide a shock absorbing assembly that prevents damage to the film membrane and a filter membrane group using the shock absorbing assembly, so as to solve the problem that when the film shakes, the position clamped by the positioning ring on the film film is subject to great stress. High-frequency jitter damages the strength and quality of this part of the film

Embodiment 1

[0051] Such as Figure 1-Figure 7 As shown, the shock absorbing assembly for preventing damage to the film of the present invention includes a positioning ring 1, a shock absorbing assembly is arranged on the side wall of the positioning ring 1, and the shock absorbing assembly includes a telescopic rod 2 connected in sequence and an elastic Assembly, one end of the telescopic rod 2 is connected to the outer wall of the positioning ring 1, and the other end of the telescopic rod 2 is connected to the elastic component, and the telescopic direction of the elastic component is parallel to the axis of the positioning ring 1.

[0052] On the permeable pipe, the 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 at the same time, the elastic component is far away from the lifting rod 2 One end of each is in contact with a soft film, such as Figure 7 shown.

[0053] When the film shak...

Embodiment 2

[0055] This embodiment is based on Embodiment 1, and further explains the elastic component.

[0056] Such as Figure 1-Figure 7 As shown, the present invention prevents the damping assembly of the film from being damaged. The elastic assembly includes a damping spring 3. Contact blocks 4 are arranged at both ends of the damping spring (3). The damping spring 3 The axis of the shaft is parallel to the axis of the positioning ring 1, its side wall is connected with the end of the telescopic rod 2 away from the positioning ring 1, and its other end is connected with the contact block 4.

[0057] When the film swings towards the positioning ring 1, the end of the side wall of the film film close to the positioning ring 1 contacts the contact block 4, and compresses the damping spring 3, and then buffers by compressing the shock absorbing spring 3 to reduce the position on the film film. The stress on the part where the ring is clamped.

[0058] Due to the setting of the shock-a...

Embodiment 3

[0063] This embodiment is based on the first embodiment, and further explains the telescopic rod 2 .

[0064] Such as Figure 1-Figure 7 As shown, the present invention prevents the damping assembly of the film film from being damaged. The telescopic rod 2 includes a fixed cylinder 5 and a screw rod 6 that are sequentially connected and coaxial. The bottom of the fixed cylinder 5 is connected with the positioning ring 1. One end of the screw rod 6 is inserted into the central hole of the fixing cylinder 5 and threadedly connected with the central hole of the fixing cylinder 5, and the other end of the screw rod 6 is connected with the elastic component.

[0065] The setting of the telescopic rod is convenient for adjusting the contact position of the film film and the shock absorbing assembly according to needs. The adjustment of the axial length of the telescopic rod can be completed by rotating the screw rod 6 .

[0066] Further, a force spring 7 is arranged in the central...

Abstract

The invention discloses a damping assembly for preventing damage of a film membrane and a filtering membrane assembly utilizing the damping assembly. The damping assembly comprises a positioning ring,wherein the side wall of the positioning ring is provided with a damping assembly body, the damping assembly body comprises a telescopic rod and two elastic assemblies which are successively connected with each other, one end of the telescopic rod is connected with the outer wall of the positioning ring, the other end of the telescopic rod is connected with the elastic assembly, the two elastic assemblies are coaxial, one end of each elastic assembly is connected with the telescopic rod, and a telescopic axis of the elastic assembly is parallel to the axis of the positioning ring. When a filmmembrane jitters, due to the arrangement of the elastic assemblies, the jittering amplitude of a part, close to the positioning ring, of the film membrane is alleviated and buffered, the stress applied to the part, clamped by the positioning ring, of the film membrane is reduced, and the strength quality of the clamped part of the film membrane is improved, so that the film membrane can successfully filter water, and the sealing performance between the positioning ring and the film membrane is improved.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a shock-absorbing assembly for preventing damage to a film membrane and a filter membrane group using the shock-absorbing assembly. 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...
