Description

Technical Field

[0001] This utility model relates to the field of water treatment membrane application technology, and in particular to a post-treatment water tank for hollow fiber membrane fibers that uniformly mixes glycerol. Background Technology

[0002] In the field of water treatment membrane applications, during the production and preparation stage of hollow fiber membrane fibers, to prevent structural pore collapse and shrinkage during drying and storage, which could lead to severe flux attenuation and significant fluctuations in other properties, a certain concentration of glycerol aqueous solution is typically used to soak the membrane fibers. Glycerol, as a pore-retaining and wetting agent, remains in the membrane fiber pore structure, providing support and thus maintaining the membrane fiber's performance. Current technology involves adding glycerol and water in a specific ratio to a soaking tank and mixing them.

[0003] For example, Chinese patent application number CN201821562355.X describes a continuous production device for post-processing of hollow fiber membranes. The frame includes, from front to back, a pure water rinsing zone, a glycerol rinsing zone, and a drying zone. The lower end of a movable support allows the fiber membrane filaments to be hung, enabling automatic cyclic movement along a circulating track, sequentially passing through each processing step. However, during production, the presence of moisture in the membrane filaments causes the concentration of the glycerol aqueous solution to continuously decrease, requiring the addition of fresh glycerol at intervals. Due to production limitations, some of this added glycerol settles at the bottom of the tank, resulting in a post-processing solution concentration lower than required for production. Furthermore, the concentration varies, with lower concentrations at the surface and higher concentrations at the bottom. This uneven concentration affects the stability of the post-processing effect and also causes problems for subsequent drying and packaging processes. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a post-treatment water tank for hollow fiber membrane fibers that can uniformly mix glycerol, so as to solve the technical problem that the existing technology causes uneven concentration of the post-treatment solution due to the presence of moisture in the membrane fibers themselves during the production process, which affects the stability of the post-treatment effect of the membrane fibers.

[0005] To achieve the above objectives, this utility model provides a post-treatment water tank for uniformly mixing hollow fiber membrane fibers, comprising a tank body, an outlet at the lower end of the tank body, and supporting beams evenly distributed within the tank body. The post-treatment water tank further includes:

[0006] A material placement frame, wherein the material placement frame has an open structure and a bundle of hollow fiber membrane filaments is placed inside, and the material placement frame is placed on the supporting crossbeam;

[0007] Aeration pipes are laid at the bottom of the water tank.

[0008] A mixing mechanism for circulating the glycerol-containing treatment solution within the water tank.

[0009] Furthermore, the upper port of the material placement frame is provided with a height-adjustable pressure plate, which abuts against the bundled hollow fiber membrane filaments.

[0010] Furthermore, the aeration port of the aeration pipe is located below the supporting crossbeam, and an aeration gap is provided between the aeration pipe and the material placement frame.

[0011] Furthermore, the hybrid mechanism includes:

[0012] A circulation pump, which is installed outside the water tank body;

[0013] The water inlet pipe has one end connected to the water outlet and the other end connected to the inlet of the circulation pump.

[0014] The water outlet pipe has one end connected to the outlet of the circulating pump and the other end extending to the upper port of the water tank.

[0015] Furthermore, there are several aeration pipes, which are spaced apart at the bottom of the water tank.

[0016] Furthermore, the outlet is positioned between the intervals of the aeration pipes.

[0017] Furthermore, several of the aforementioned aeration pipes are connected to an air compressor or other air source via air inlet pipes.

[0018] Furthermore, the bottom of the water tank is equipped with casters.

[0019] The beneficial effects of this invention are as follows: This invention utilizes a hollow fiber membrane post-treatment water tank that ensures uniform mixing of glycerol. During use, a mixing mechanism drives the circulation of the glycerol-containing treatment liquid, guaranteeing a certain degree of mixing between glycerol and water. Aeration pipes also aerate the glycerol-containing treatment liquid within the tank. In autumn and winter when temperatures are low, viscous glycerol tends to settle at the bottom of the tank. The aeration process causes the glycerol at the bottom of the tank to churn, and combined with the circulation of the glycerol-containing treatment liquid by the mixing mechanism, this allows the glycerol to move more actively, further enhancing the uniform mixing effect of glycerol in the treatment liquid.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0029] An embodiment of this utility model proposes a post-treatment water tank for hollow fiber membrane fibers to uniformly mix glycerol, such as... Figure 1-4As shown, the system includes a water tank body 1, with a water outlet 2 at the lower end of the water tank body 1. Supporting crossbeams 3 are evenly distributed inside the water tank body 1. The post-treatment water tank also includes:

[0030] Material placement frame 4, which has an open structure and contains bundles of hollow fiber membrane filaments 5, is placed on the supporting beam 3.

[0031] Aeration pipe 6 is laid at the bottom of the water tank 1;

[0032] A mixing mechanism for circulating the glycerol-containing treatment solution in the water tank 1.

[0033] In this embodiment, the upper port of the material placement frame 4 is provided with an adjustable height pressure plate 7. The pressure plate 7 abuts against the bundled hollow fiber membrane filaments 5. By adjusting the installation height of the pressure plate 7 on the material placement frame 4, the bundled hollow fiber membrane filaments 5 with different placement amounts can be pressed and limited, avoiding incomplete soaking due to the bundled hollow fiber membrane filaments 5 floating upwards.

[0034] In this embodiment, the aeration port of the aeration pipe 6 is located below the supporting beam 3, and an aeration gap is set between the aeration pipe 6 and the material placement frame 4 to avoid the material placement frame 4 affecting the aeration effect, ensuring that all membrane fibers are immersed in the post-treatment liquid and ensuring the treatment effect.

[0035] In this embodiment, the mixing mechanism includes:

[0036] Circulation pump 8 is installed on the outside of the water tank 1;

[0037] Water inlet pipe 9, one end of which is connected to water outlet 2, and the other end of which is connected to the inlet of circulating pump 8;

[0038] The water outlet pipe 10 has one end connected to the outlet of the circulating pump 8, and the other end extends to the upper port of the water tank 1.

[0039] In this embodiment, as Figure 3 As shown, there are several aeration pipes 6, which are spaced apart at the bottom of the water tank 1, so that multiple material placement frames 4 can be placed in the material placement frame 4, thereby improving the production efficiency of fiber membrane filaments.

[0040] In this embodiment, the outlet 2 is placed between the intervals of the aeration pipes 6 to avoid the aeration pipes 6 affecting the circulation effect of the glycerol-containing treatment liquid.

[0041] Working process and principle: In this embodiment, during use, bundles of hollow fiber membrane filaments 5 are placed in the feeding frame 4 and pressed against the bundles of hollow fiber membrane filaments 5 by the pressure plate 7. Glycerin-containing treatment liquid is introduced into the water tank 1 until the feeding frame 4 is submerged in the glycerin-containing treatment liquid. The circulating pump 8 in the mixing mechanism drives the glycerin-containing treatment liquid to be drawn out from the outlet 2 and discharged back into the water tank 1, so that the circulating glycerin-containing treatment liquid is sprayed into the water tank 1 again, thereby ensuring the mixing effect of glycerin and water in the glycerin-containing treatment liquid to a certain extent.

[0042] Simultaneously, aeration is introduced into the glycerol-containing treatment solution within the water tank 1 via aeration pipe 6. During the autumn and winter seasons when temperatures are low, viscous glycerol settles at the bottom of the water tank 1. The aeration process causes the glycerol at the bottom of the water tank 1 to churn, which, combined with the circulation of the glycerol-containing treatment solution by the mixing mechanism, allows the glycerol to move more actively, further enhancing the uniformity of the glycerol mixing in the treatment solution.

[0043] In this embodiment, as Figure 1 , Figure 2 As shown, several aeration pipes 6 are connected to an air compressor or other air source via air inlet pipes 11. Aeration is applied to the glycerol-containing treatment liquid through multiple aeration pipes 6, which can form an aeration cover on the material placement frame 4.

[0044] In this embodiment, as Figure 1 , Figure 2 As shown, the bottom of the water tank 1 is equipped with casters 12, which can be easily and conveniently pushed to the designated area or the direction of the post-treatment water tank can be adjusted at any time according to production needs and site conditions.

[0046] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
