Description

Hollow fiber membrane cleaning device

technical field

The utility model relates to the technical field of cleaning devices, in particular to a hollow fiber membrane cleaning device.

Background technique

During the production of hollow fiber membranes, some solvents or additives will remain in the hollow fiber membranes, and the remaining solvents and other substances that must be removed need to be removed, especially the solvents that are harmful to the human body in the inner cavity must be cleaned. At present, the cleaning method used is to use a large amount of ultrafiltration water or reverse osmosis water to continuously soak and rinse the hollow fiber membrane for a long time. Since the inner diameter of some hollow fiber membranes is relatively small, the Solvents are still difficult to clean. The equipment takes a long time to clean, consumes a large amount of cleaning agent, has a complex structure, and has high operating costs.

Utility model content

The technical problem to be solved by the utility model is: in order to overcome the above-mentioned problems, provide a hollow fiber membrane cleaning device with simple structure, convenient use and clean cleaning.

The technical solution adopted by the utility model to solve the technical problem is: a hollow fiber membrane cleaning device, including a box body, a water inlet and a water discharge port connected with the box body, and left inlets on both sides of the bottom of the box body. The air hole and the right air inlet and the air compressor connected with the left air inlet and the right air inlet, the pipeline arranged in the box is connected between the left air inlet and the right air inlet, the said At least one discharge hole is opened on the pipeline.

In order to allow more gas to be discharged, the air outlet holes have three rows, and the number of each row is 10-20.

The beneficial effects of the utility model are: the hollow fiber membrane cleaning device of the utility model adopts the connection between the air compressor and the pipeline. It circulates in the inner cavity of the hollow fiber membrane, so that the impurities and residual solvents in the hollow fiber membrane can be cleaned. The design and structure of this device are simple, easy to use, and low in cost.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the structural representation of the utility model.

Among the figure 1. casing, 11. water inlet, 12. drain, 2. left air inlet, 3. right air inlet, 4. air compressor, 5. pipeline, 51. air outlet.

Detailed ways

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

The hollow fiber membrane cleaning device as shown in Figure 1 comprises a casing 1, a water inlet 11 is provided on the upper edge of the casing 1, a drain 12 is provided at the bottom of the casing 1, and a water outlet 12 is respectively opened on both sides of the bottom of the casing 1. There are left air inlet 2 and right air inlet 3, the left air inlet 2 and the right air inlet 3 communicate with the air compressor 4 arranged on the outside of the box body 1, the left air inlet 2 and the right air inlet 3 The pipes 5 arranged in the inner cavity of the box body 1 are connected between them, and the pipes 5 are provided with three air outlet holes 51, the number of each air outlet hole 51 is 15, and the distance between two adjacent air outlet holes 51 is equal.

The working principle of the hollow fiber membrane cleaning device of the utility model: inject liquid into the box body 1 through the water inlet 11, put the hollow fiber membrane into the liquid, and then turn on the air compressor 4, which generates air from the left The air hole 2 and the right air inlet 3 enter, and the air is uniformly and quickly discharged from the air outlet 51 on the pipe 5, and the circulating flow of liquid flows into the inner cavity of the hollow fiber membrane, thereby cleaning the inner cavity of the hollow fiber membrane.

Inspired by the above-mentioned ideal embodiment according to the utility model, and through the above-mentioned description content, relevant staff can completely make various changes and modifications within the scope of not deviating from the technical idea of the utility model. The technical scope of this utility model is not limited to the content in the description, but must be determined according to the scope of the claims.
